Abstract: A connector has a housing (30) with side-by-side cavities (31). A resiliently deformable lock (40) is formed in each cavity (31) for locking terminal fittings (10) in the respective cavities (31). Locks (40) of adjacent cavities (31) are coupled by coupling pieces (51) to enhance the strength of the locks (40).

Abstract: A connector includes a housing (10) and a retainer (40) that can be moved from a partial locking position to a full locking position in the housing (10). Terminal fittings (30) can be inserted into the housing (10) when the retainer (40) is at the partial locking position. However, the retainer (40) locks the terminal fittings (30) when the retainer is moved to the full locking position. Pairs of partial locks (50° F., 50 R) prevent the retainer (40) from moving loosely from the partial locking position toward the full locking position. Pairs of full locks (51° F., 51 R) prevent the retainer (40) from moving loosely from the full locking position toward the partial locking position.

Abstract: A retainer (40) has left and right pivotally displaceable locking pieces (47) and is held at a partial locking position on a housing (30) by the engagement of engageable portions (50) at the leading ends of the locking pieces (47) with partial locking projections (31) on the housing (30). Thus, even if the retainer (40) is pushed inadvertently, such a push is restricted by the contact of the contact surfaces with the restricting surfaces (37). Pressable portions (55) of the locking pieces (47) can be pressed while holding the opposite side surfaces of the retainer (40) by fingers. This causes the locking pieces (47) to displace pivotally outward and the engageable portions (50) disengage from the restricting surfaces (37). Thus, the retainer (40) can be pushed to a full locking position.

Abstract: A connector has a housing (10) formed with cavities (11) for receiving male terminal fittings (40). Each cavity (11) has a receiving surface (16) substantially normal to an inserting direction of the male terminal fitting (40), and each male terminal fitting (40) has a contact surface (50) substantially normal to the inserting direction. The inserted male terminal fitting (40) is stopped at a front-limit position by bringing the contact surface (50) thereof into contact with the receiving surface (16) in the cavity (11) substantially in the same direction as the inserting direction of the male terminal fitting (40). Thus, the male terminal fitting (40) can be stopped at a proper insertion position.

Abstract: Reinforcements (19) bulge out toward the center of a tab insertion opening (14) from corners of an opening edge of the tab insertion opening (14) extending along a partition wall (18) of a connector housing (10). The partition wall (18) is made thicker and stronger by the reinforcements (19). Thus, the partition wall (18) is prevented from damage and/or deformation even if a tab (21a) or the like strikes against the partition wall. The partition wall (18) is made thicker only at the ends of the side edge of the tab insertion opening (14) extending along the partition wall (18). Thus, an opening area of the tab insertion opening (14) still is substantially rectangular and the insertion of the tab (21a) is not hindered.

Abstract: A connector is capable of being miniaturised, whilst inadvertent pushing in of a retainer is prevented. A housing main body 2 into which female terminal fittings are inserted has a retainer insertion groove 23 formed on a side face thereof, a retainer 14 being inserted into this retainer insertion groove 23. The retainer 14 is maintained in a temporary stopping position which allows the insertion of the female terminal fittings into cavities thereof. After that, the retainer 14 is pushed further in and maintained in a main stopping position where is engages stepped members of the female terminal fittings. When the retainer 14 is in the temporary stopping position, the posterior end (relative to the direction of insertion) of this retainer 14 is inside the housing main body 2. As a result, the retainer 14 is not pushed inadvertently into the main stopping position while, for example, the connector is being transported to a site where the female terminal fittings are to be inserted.

Abstract: A connector has a housing (20) with cavities (26) for receiving terminals (10). A lock (30) projects is provided in each cavity (26) and has a forwardly tapered locking surface (32) that is sloped to project more forward at the base than at the top. The connector also has a retainer (50) with a restricting plate (53) to prevent displacement of the locks (30) toward deformation spaces (36). Push-up protrusions (60) of the restricting plate (53) slip under the lower surfaces of the locks (30) as the retainer (50) is pushed towards a full locking position and push the locks (30) up towards cavities (26). A cam action of the sloped locking surfaces (32) pushes the female terminals (10) forward and against front walls (27).

Each arm has a resiliently movable free end portion positioned to releasably engage the protrusion when the contact is in the contact cavity at which the spring arm is positioned. The end portion of each arm and the stop for each contact cavity are spaced apart to receive the contact protrusion therebetween. The arm is resiliently movable to permit insertion and removal of the contact through the open end.

Abstract: The invention is directed to a terminal stabilization device utilizing primary latching reinforcement that is operable in an electrical connector assembly and includes a first housing unit having a contact member extending outwardly from a base surface of the first housing unit, a plurality of fingers protruding from the base surface of the first housing unit, a second housing unit having a contact member support positioned on the second housing unit to cradle the contact member, the contact member support having a plurality of engagement members extending therefrom, wherein when the upper housing unit and the lower housing unit are joined, the contact member, the fingers, and the engagement members form a receptacle for said terminal and said terminal is stabilized in position.

Abstract: A connector has a housing (10) with a cavity (11) and a resiliently deformable lock (13) for locking a female terminal fitting (30) in the cavity (11). The lock (13) has a base (25) and a projection (26) that projects into the cavity (11) from the base (25). Both side surfaces (25b) of the base (25) are formed by a mold that is moved forward to open, and notches (17a) are formed in the front surface of the female housing (10) by this mold. The notches (17a) extend more outward than inner side surfaces (11b) of the cavity (11) with respect to the widthwise direction. Both side surfaces (26c) of the projection (26) are formed by a mold moved backward to open. The projection (26) is narrower than the base (25).

Abstract: A connector housing (30) has a cavity (31) and a resiliently deformable lock (40) cantilevers forwardly from a wall (35) of the cavity (31) for engaging a locking surface (24) of a terminal fitting (10) inserted into the cavity (31). A base end of the lock (40) has a thinned portion (52). A backward pulling force on the female terminal fitting (10) creates a compressive force on the lock (40) in the longitudinal direction. Thus, the lock (40) undergoes such a resilient deformation at the thinned portion (52) that the length (L1) of the lock (40) becomes shorter than its natural length (L0). Buckling strength is enhanced by as much as the lock (40) is shortened and, as a result, a force for locking the female terminal fitting (10) is enhanced.

Abstract: A female housing (10) has cavities (11) into which female terminal fittings (30) are insertable from behind. A lock (13) projects forward from its base end and is restorable after being temporarily resiliently deformed by the female terminal fitting (30) being inserted, thereby engaging and locking the female terminal fitting (30) in the cavity (11). Maneuverable recesses (24) maneuverable by a disengagement jig (60) from front are provided at positions on the front surface of each lock (13) retracted from the locked terminal fitting (30) and within a width range of a locking surface of the lock (13) engageable with the terminal fitting (30) and located more toward the base end of the locking portion than the locking surface.

Abstract: In a connector including a housing and a contact held in the housing for being brought into contact with a connection object, the contact includes a contacting portion surrounded by a wall portion to which a locking portion connected. The housing has a displaceable housing lance. The wall portion has first and second side walls faced to each other with a space left therebetween. The locking portion extends from the first wide wall towards the second side wall and has an extending end. The second side wall has a locking/holding portion holding the extending end. Thus, the locking portion is adapted to be engaged with the housing lance.

Abstract: A hermaphroditic connector is provided having a housing with a rear end configured to receive a cable. A socket is provided on the front end of the housing and extends forwardly therefrom. The socket includes a shroud and a socket tongue formed on the housing and defining a pocket opening onto a front face of the socket. The shroud and socket tongue are configured to mate with another hermaphroditic connector having a similar shape. The socket includes at least one blocking member in the opening in the front face to interfere with foreign objects that may inadvertently come into contact with the enclosed conductive member. The blocking member may include ribs and/or beveled corner inserts provided in the pocket and extending at least partially along the length of the socket. A contact is held within the pocket and is configured to join a power, signal or ground cable.

Abstract: A terminal fitting (30) is provided for insertion into a female housing (10) from behind. The terminal fitting (30) has an outer wall (37) with a cut-away portion (44) that permits entrance of a lock (13). Thus, the outer wall (37) is divided into a front portion and a rear portion. A locking projection (52) with which the lock (13) is engageable for locking is provided by causing a front cut end of the cut-away portion (44) to project outward. The lock (13) is engageable with a front cut end surface (44a) of the cut-away portion (44) including the locking projection (52).

Abstract: Provided is a connector designed for double retention of a terminal fitting, which inhibits flexure of a flexible lance retaining the terminal fitting by pushing a front holder from a temporary retention position into a full retention position. The connector includes at least any one of abutting planes of a retaining protrusion and a retention arm performing temporary retention of the front holder, as an element to strengthen retention when pushing force is applied to the front holder. Specifically, said abutting plane is formed as an inclined plane with an angle in a direction of generating bites upon application of pushing force. And the connector is designed to effectuate release of retention by means of inserting a retention release jig from a front side of the connector housing.

Abstract: A connector has male and female housings (10, 40) that are connectable with one another. A moving plate (30) is movable in the male housing (10) from a first position to a second position during the connection process. A resistance arm (36) on the moving plate (30) must deflect to pass an abutting surface (21) on the male housing (10) during connection, and a lock arm (46) on the female housing (40) must deflect to pass a locking section (25) of the male housing (10) during connection. Resistance forces for deflecting the resistance arm (36) and the lock arm (46) reach peaks substantially simultaneously and before terminal fittings of the housings (10, 40) engage.

The carrier comprises a housing, means for managing and securing terminated cable assemblies to the carrier, such as a combination of a clip and a cross-clip, and means for fastening a header onto the housing. The carrier provides controlled impedance and allows for quick and easy access to the header and the terminated cable assemblies in the event that replacement is necessary.

Abstract: A tamper resistant pin connection for use in a plasma arc cutting apparatus is provided that comprises a plurality of locking fingers within a hollow internal channel of a housing that secure a negative lead gas carrying pin within the housing. The pin comprises a first collar with a shoulder disposed thereon, and accordingly, the locking fingers engage the shoulder to secure the pin within the housing. The pin further comprises a second collar that blocks access to the locking fingers through a first portion of the hollow internal channel such that the locking fingers cannot be accessed to disengage the pin. Further, the pin is recessed within a second portion of the hollow internal channel to prevent further access to the pin for a tamper resistant pin connection.

Abstract: Cavities (21) into which terminal fittings (10) are insertable from behind are arranged at upper and lower stages in a housing (20), and locks (28) are provided at the lower surfaces of the respective cavities (21). Each lock (28) is formed by cutting a partition wall (22) partitioning the upper and lower cavities (21) or a bottom wall (23) of the housing (20), and includes an arm (29) supported at both front and rear ends. A locking section (30) engageable with an engaging edge (15) of the corresponding terminal fitting (10) is provided on the upper surface of each arm portion (29) to project into the cavity (21). When the terminal fitting (10) is inserted into the cavity (21), the locking section (30) is pushed by the terminal fitting (10) to resiliently deform the arm (29) into a substantially arched shape with its coupled portions at the front and rear ends as supporting points.

Abstract: A terminal fitting (1) has connecting portion (5) with an engaging portion (14) to be engaged with a resin lock (13) of a connector (3). The engaging portion (14) projects with a step from an upper wall (12) to ensure a large engaging area with the resin lock (13). An outer edge (14A) of the engaging portion (14) is closer to the resin lock (13) than an inner edge (14B) thereof. Thus, when the terminal fitting (1) is pulled back in withdrawing direction, a force acts to move the leading end of the resin lock (13) from the outer edge (14A) of the engaging portion (14) toward the inner edge (14B). Therefore, the terminal fitting (1) is difficult to disengage from the resin lock (13), and a large engaging force is secured.

Abstract: A connector has a housing (10) with cavities (11) for receiving terminal fittings (21). Each cavity (11) has a lock (12) with a fastening portion (13) for locking the terminal fitting (21). A jig contact portion (14) is formed at the side of the fastening portion (13). A withdrawing jig (J) comes into sliding contact with the jig contact portion (14) to deform the lock (12) away from the terminal fitting (21) to cancel the locked state. The front end (14F) of the jig contact portion (14) is more backward than the front end (13F) of the fastening portion (13). Thus, a stroke of the sliding-contact accompanied by frictional resistance between the withdrawing jig (J) and the jig contact portion (14) is shortened, and frictional resistance is reduced during the insertion of the withdrawing jig (J).

Abstract: A connector has a housing (10) with cavities (11) for receiving terminal fittings (40). Locks (17) lock the terminal fittings (40) in the cavities (11) and serve also as partition walls (20) between cavities (11) for the miniaturization of the connector. Upside-down insertion preventing portions (46) are provided on the terminal fittings (40), but are disposed so as not to interfere with the corresponding lock (17). The upside-down insertion preventing portions (46) also do not interfere with the lock (17) of the adjacent cavity (11) even if both the upside-down insertion preventing portion (46) and the lock (17) are near the front end and are on opposite sides. Since the upside-down insertion preventing portions (46) and the locks (17) are near the front end, inserting resistance is low and an earlier detection of upside-down insertion is realized.

Abstract: Properly inserted terminal fittings (40) are engaged and locked by locks (20) returned to their free states. A retainer (30) mounted into a housing (10) then enters deformation spaces (26) for the locks (20). The retainer (30) presses and deforms the locks (20) from their free states toward the terminal fittings (40). Thus, areas of engagement of the locks (20) and the terminal fittings (40) are increased. Additionally, the degree of the resilient deformation of the locks (20) in the inserting process of the terminal fittings (40) is low and resistance acting when the terminal fittings (40) are inserted is suppressed.

Abstract: An electrical connector includes a socket connector engagable with a plug connector. The plug connector slides into a recess of the socket connector and is securely guided and aligned with connection terminals during insertion. Complementary joining parts on the inside of the recess and the outer surface of the socket connector engage, prevent the socket connector from damaging the connection terminals in the recess, and securely guide the socket connector during insertion and reuse.

Abstract: A female terminal fitting (1) has a rectangular tubular connecting portion (5) for connection with a male tab (4). First and second contacts (9C, 18) are provided respectively on first and second opposed walls (23, 17) of the connecting portion (5). The contacts (9C, 18) resiliently contact and hold the male tab (4). The first contact (9C) is provided at the leading end of a resilient contact piece (9). An engaging edge (25) projects from one side of a base (9A) of the resilient contact piece (9) and is fit into a locking hole (26) formed in a sidewall (15) to position the base (9A) of the resilient contact piece (9) and prevent it from being raised.

Abstract: Apparatus, methods and articles of manufacture for terminal position assurance are shown, comprised of a housing with pin contact and terminal position assurance means. The terminal position assurance means, as it is installed within the housing, provides a tab that engages a finger within the housing, thereby driving the finger into a recess within the pin contact, and so seating the pin contact within the housing. If more than one pin contact is within the housing, more than one tab and finger are provided. The terminal position assurance means further contains a recess for retrieval so it may be retrieved in the event of maintenance, disassembly, etc. on the connector.

Abstract: A terminal fitting (30) has a rectangular tubular main body (31) with a ceiling wall (33), first and second sidewalls (34, 35) extending down from the opposite sides of the ceiling wall (33), a bottom wall (36) projecting from the first sidewall (34) to face the ceiling wall (33), and an outer wall (37) projecting from the second side wall (35) and placed on the outer side of the bottom wall (36). A front-portion holding piece (50) projects from a front portion (37a) of the outer wall (37) and engages a front-portion holding groove (51) in the first sidewall (34). A restrictable projection (70) is provided at the rear end of the front-portion holding piece (50), and engages a restricting groove (71) of the front-portion holding groove (51) for restricting an opening deformation of the outer wall (37).

Abstract: A connector has a housing (20) with cavities (25) for receiving terminal fittings (10). A resiliently deformable lock (30) extends along a wall (25A) of each cavity (25) and is configured for locking the terminal fitting in the cavity (25). An elongated projection (31) is formed at a widthwise center position of the upper surface of each lock (30) and an escaping groove (34) is formed in the wall (25A) of each cavity (25) for receiving the elongated projection (31) when the lock (30) deforms. The elongated projection (31) reinforces the lock (30) and provides a large engaging area with the terminal fitting (10). Additionally, the escaping groove (34) provides a necessary a deformation permitting space (35) for the thicker lock (30) without increasing the height of the housing (20).

Abstract: A connector comprises a housing main body 27, a stopper having a flexibility, and a spacer 29. The housing main body is provided with a deflection restricting means 37 which with said spacer 29 in contact with said stopper 35, restricts said stopper 35 from being deflected in the installation direction of said spacer 29 onto said housing main body 27.

Abstract: A connector housing has a terminal insertion opening (32) formed on a front wall (30) of a cavity (23) formed in a tower part (21). A tapered guide surface (33) is formed on a front peripheral edge of the terminal insertion opening (32). An open groove (35) is formed forward of the lance (27) on a lower portion of the peripheral edge of the terminal insertion opening (32). A retainer (40) for unremovably doubly locking a female terminal can be mounted in the tower part (21). An auxiliary plate (60) projects from a lower portion of a peripheral edge of each window hole (43) of the retainer (40). A supplementary tapered guide surface (33A) is formed on a surface of an upper end of the auxiliary plate (60). A jig insertion hole (64) is formed on the auxiliary plate (60). When the retainer (40) is mounted in a main locking position, the auxiliary plate (60) fits into a cut-off portion of the peripheral edge of the terminal insertion opening (32).

Abstract: A female terminal fitting (30) is provided for insertion into a female housing (10) from behind. A rear end of an outer wall (37) of the female terminal fitting (30) extending along widthwise direction is embossed to project out, thereby forming a locking projection (52) with a vertex (A) at its front end. The female terminal fitting (30) is inserted into the female housing (10) and a lock (13) in the female housing (10) engages the locking projection (52). The locking projection (52) is more outward than an imaginary triangular pyramid (X) formed by connecting the vertex (A) at the front end, a pair of base end points (B) at the rear edge, and an outward-projecting end point (C).

Abstract: A connector has a housing (11) with a cavity (12) for receiving a rectangular tube (Ta) of a terminal fitting (T). A lock (13) is formed on a surface of the cavity (12) for engaging the terminal fitting (T). The cavity (11) has a first guiding surface (14a) at a corner adjacent a surface of the cavity (12) opposed to the lock (13) for narrowing the width of a cavity (12). A retainer (21) engages a lower surface of the lock (13) for pressing the lock (13) and the terminal fitting (T) up into the first guiding surface (14a) to prevent shaking of the terminal fitting (T) in the cavity (12).

Abstract: A retainer (40) has left and right pivotally displaceable locking pieces (47) and is held at a partial locking position on a housing (30) by the engagement of engageable portions (50) at the leading ends of the locking pieces (47) with partial locking projections (31) on the housing (30). Thus, even if the retainer (40) is pushed inadvertently, such a push is restricted by the contact of the contact surfaces with the restricting surfaces (37). Pressable portions (55) of the locking pieces (47) can be pressed while holding the opposite side surfaces of the retainer (40) by fingers. This causes the locking pieces (47) to displace pivotally outward and the engageable portions (50) disengage from the restricting surfaces (37). Thus, the retainer (40) can be pushed to a full locking position.

Abstract: A connector has a housing (20) and a retainer (40) with a pair of side pieces (42). The side pieces (42) are fitted into retainer mount recesses (31) in the opposite side surfaces of the housing (20). Dovetail grooves (34) and dovetail projections (46) are provided between the side pieces (42) of the retainer (40) and the housing (20). Thus, disengagement of the side pieces (42) from the retainer mount recesses (31) can be prevented, thereby preventing the retainer (40) from being detached from the housing (20) while operating the retainer (40).

Abstract: A connector has a housing (40) with cavities (41) and resiliently deformable locks (43) that project into the cavities (41). Terminal fittings (10) are insertable into the cavities (41) and deform the locks (43) in a deforming direction (DD) that intersects the inserting and withdrawing directions (IWD) of the terminal fitting (10). The locks (43) then restore and locking surfaces (64) of the locks (43) lock the terminal fittings (10) in the cavities (41). Each locking surface (64) has an upper locking surface (58) furthest into the cavity (41) and a lower locking surface (61). The lower locking surface (61) is at an obtuse angle to the withdrawing direction of the terminal fitting (10), whereas an angle of the upper locking surface (58) to the withdrawing direction is smaller than the angle of the lower locking surface (61).

Abstract: A connector housing (10) has a wide cavity group (11L) and a narrow cavity group (11S). A front holder (30) is mounted to the front of the housing (10), but corresponds only to the narrow cavity group (11S). Thus, the front holder (30) has a small area as compared to a front holder corresponding to all the cavities. Accordingly, a degree of shrinkage of the front holder (30) during resin molding is suppressed, thereby making a dimensional variation of the front holder (30) smaller. As a result, displacements between the smaller cavities (12S) and the portions of the front holder (30) corresponding to the smaller cavities (12S) are suppressed.

Abstract: A connector (1) is configured in a manner that two stages of insulation housings (23) are disposed therein each of which is additionally provided with common terminal chambers (28) each capable of housing a crimp-style terminal or a crimped terminal (25) or a press contact terminal (26) thereby to house the crimped terminals (25) and the press contact terminals (26) in a mixed manner within the connector. The common terminal chambers (28) of each of the insulation housings (23) are formed by partition walls (29) erected from a base plate portion (27), and the crimped terminal (25) or the press contact terminal (26) is inserted from the upper opening of each of the common terminal chambers (28).

Abstract: A rear holder 4 is inserted into a housing 3 from a rear end surface 24 at a provisional locking position in which the rear holder 4 is inserted into the housing 3 halfway and an insertion of connecting terminals is allowed, as well as at a sufficiently inserted complete locking position at which the inserted connecting terminals are locked. Within the housing 3, there are formed two rows of terminal accommodating holes 28 each accommodating respective connecting terminals. The rear holder 4 is formed in a substantially plate-like shape and includes a main body 41 which is inserted into slits 29 of the housing 3 and locking arms 45 which are inserted into respective terminal accommodating holes 28. A width of a locking arm 45 is slightly smaller than that of a terminal accommodating hole 28. Windows 37 are formed in the outer wall 21 of the housing 3 such that the terminal accommodating holes 28 are communicated with external through the windows 37.

Abstract: A connector includes a housing, a front holder, a provisionally-retaining member and a completely-retaining member. The housing includes a plurality of terminal receiving chambers in which metal terminals are accommodated and a plurality of elastic retaining arm portions for respectively retaining the metal terminals. The front holder is attached to the housing in a completely-retaining position through a provisionally-retaining position. The front holder prevents the elastic deformation of the elastic retaining arm portions in the completely-retaining position. The front holder allows the elastic deformation of the elastic retaining arm portions in the provisionally-retaining position. The provisionally-retaining member retains the front holder to the housing in the provisionally-retaining position. The completely-retaining member retains the front holder to the housing in the completely-retaining position.

Abstract: A connector housing (20) has cavities (21) and locks (31) for engaging terminal fittings (10) inserted into the cavities (21). Each lock (31) has an arm (32) and a locking section (33) that projects up from the arm (32). A mold-removal hole (35) is formed in a front wall (27) and in the arm (32). A tab insertion hole (28) is formed in the front wall (27) above the mold-removal hole (35) for receiving a tab terminal (T), and a guide surface (29) is formed at the front edge of the tab insertion hole (28) for guiding the tab (T). Upwardly narrowed portions (38) narrowed are formed on the locking section (33) and have a height overlapping the height of the guide surface (29). Portions of the mold-removal hole (35) corresponding to the narrowed portions (38) define an M-shaped when viewed from the front.

Abstract: A rubber plug (30) is disposed on a rear surface of a male housing (10). A plug hold-down plate (40) for holding down the rubber plug (30) is disposed on a rear surface of the rubber plug (30). A holder (50) can be held at a temporary locking position apart from a rear surface of the plug hold-down plate (40) and a main locking position at which the holder (50) contacts the rear surface of the plug hold-down plate (40). If a mounted male terminal fitting (2) is pulled out, with the holder (50) held at the temporary locking position, the plug hold-down plate (40) holds down the rubber plug (30). Thus the rubber plug (30) can be prevented from moving rearward.

Abstract: A terminal fitting (20) has a bottom wall (25) and first and second sidewalls (26) bent angularly from the sidewalls (26). A locking hole (28) is formed in the bottom wall (28) and extends to the sidewalls (26). A pair of notches (29) is formed in each sidewall (26) and communicates with the locking hole (28). Areas (26A) of each sidewall (26) between the respective pair of notches (29) is substantially planar and has a bottom edge substantially at the same height as the lower surface of a bottom wall (25).

Abstract: A side spacer structure in a connector has lances respectively attached from side portions of a connector housing having a plurality of terminal receiving chambers to the connector housing and used for temporarily retaining terminals inserted into terminal receiving chambers, and securing portions for securing the terminal in a state for operation. In a position where a side spacer is temporarily retained in the connector housing, a recess portion is formed in a region of the branch plate of the side spacer inserted into the connector housing, the region facing the lower portion of the terminal receiving chamber.

Abstract: A connector has a housing (20) with a receptacle (22) and locks (24) for engaging male terminal fittings (10) in the housing (20). A retainer (30) is mounted in the receptacle (22) and has a preventing plate (31) that projects into a deformation permitting spaces (25) for preventing resilient deformation of locks (24) and doubly locking the terminal fittings (10) in the housing (20). A mating housing (60) can be fit into the receptacle (22) and pushes the retainer (30) back to a pushed-in position while resiliently compressing a spring (43). When the housing (60) is withdrawn from the receptacle (22), the retainer (30) is pushed back by a resilient restoring force of the spring (43). During this time, insertion holes (32) of the retainer (30) move along tabs (12) of the terminal fittings (10) for automatically correcting misalignment.

When the housing (60) is withdrawn from the receptacle (22), the retainer (30) is pushed back by a resilient restoring force of the spring (43). During this time, insertion holes (32) of the retainer (30) move along tabs (12) of the terminal fittings (10) for automatically correcting misalignment.

Abstract: A housing (10) is formed with resin locks (15) that cantilever forward along inner walls of cavities (13) into which terminal fittings (30) can be inserted, and a mold-removal space (17) extends from the resin locks (15) to the front end surface of the housing (10). A loose movement restricting member (20) is fit into the mold-removal space (17) and contacts the terminal fittings (30) to restrict loose movement of the terminal fittings (30). The width of the mold-removal space (17) can be set freely because a part separate from the housing (10) is fitted into the mold-removal space (17) for restricting the loose movements of the terminal fittings (30). Therefore, the resin locks (15) can be wide and sufficiently strong.

Abstract: A holder-equipped connector with a downsized connector housing is provided, which includes: a terminal; a connector housing provided with a lance to primarily lock the terminal; and a holder to hold the terminal, wherein a relief portion to secure a bending amount of the lance, being bent when the terminal is attached to the connector housing, is provided on a basewall of the connector housing. The relief portion is a groove provided from a front opening of the connector housing to a vicinity of a root of the lance linearly in a terminal inserting direction.

Abstract: A housing (31) has cavities (32A), and a lance for locking terminal fittings (20) in the cavities (32A). A region of a lower wall (33) of the housing (31) forward from the lance (37) is formed as an open part (38). Thus, it is possible to make the entire lower wall (33) thin, and the housing (31) can be inserted into a smaller through-hole (19). A rib (39) projects between the open parts (38) of adjacent cavities (32A) and (32A) to increase a distance water would have to creep between the cavities (32A) and (32A). Therefore if a connector (30) is exposed to water, it is possible to prevent a short circuit between the cavities (32A) and (32A).

Abstract: An elastic portion (24) is provided at a bottom surface of a fitting hole (22) formed in a housing (21) of a female connector (20). When a housing (31) of a male connector (30) reaches a reference position (B) during a connector-fitting operation, a bottom surface of the housing (31) contacts a distal end portion (24b) of the elastic portion (24), and presses and displaces this distal end portion (24b) downward. Because of a reaction force produced as a result of this displacement, the elastic portion (24) keeps on urging the housing (31) of the male connector (30) in a direction (upward) of fitting of a lock portion (33) into a lock portion-retaining portion (33).
