Abstract: A terminal fitting (10) has a main body (11) and stabilizer (17) for preventing upside-down insertion stands up from a surface of the main body (11). Elongated projections (50) extend from a surface of the main body (11) opposite the stabilizer (17). If the male terminal fitting (10) is inserted upside down, the elongated projections (50) contact a bottom wall (24B) at the entrance of a cavity (24) during the insertion to shift the male terminal fitting (10) transversely. Thus, the stabilizer (17) is caught deeply by a ceiling wall (24C) at the entrance. As a result, the male terminal fitting (10) is prevented from any further insertion.

Abstract: A connector has a housing (10) with cavities (11) into which terminal fittings (30) are insertable. Locks (13) in the housing (10) deform during insertion of the terminal fittings (30) into the cavities (11), but then resiliently restore to lock the terminal fittings (30) in the cavities (11). Lowered portions (12a) of a bottom wall (12) of the housing (10) face the locks (12) and prevent the locks (13) from being excessively deformed. The bottom surface of each lock (13) has a convex arcuate surface (13c) and each lowered portion (12a) of the bottom wall (12) has a recess (12b) substantially conforming to the convex arcuate surface (13c) to accommodate the convex arcuate surface (13c) when the lock (13) deforms.

Abstract: A connector has a housing (1) and retainer mount hole (8) is open in the housing (1) from its bottom surface over to its opposite side surfaces. Upon being moved from a partial locking position to a full locking position, A retainer (7) can be moved from a partial locking position to a full locking position and is guided obliquely forward by guides (22-25). Thus, the retainer (7) can be constantly guided to a specified position regardless of a variation in the fitted position of the retainer (7) in the retainer mount hole (8) along forward and backward directions. Since the retainer (7) and terminal fittings (4) can constantly have a proper positional relationship, a problem of a varying function of the retainer (7) to detect the insufficiently inserted states of the terminal fittings (4) due to a variation in the fitted position of the retainer (7) can be solved.

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 including a connector housing with a retainer attachment hole that receives and stabilizes a retainer as it is inserted into the connector housing. The retainer attachment hole extends into an anterior face of the connector housing. Male terminal fittings inserted into the connector housing are maintained therein by a removal preventing member of the retainer that is inserted into the retainer attachment hole. Guiding members formed on the retainer enter the retainer attachment hole before the removal preventing member enters therein. Consequently, the retainer is stabilized and maintained in position relative to the connector housing while it is being attached to the retainer attachment hole.

Abstract: A connector has a housing (20) formed with cavities (21) for receiving terminal fittings (10). A retainer insertion hole (27) is formed in the bottom surface of the housing (20) over the entire width, and a retainer (40) provided with fasteners (44) is insertable into the retainer insertion hole (27). Locking pieces (45) at the opposite ends of the retainer (40) engage in insertion grooves (29) formed in side surfaces of the housing (20). The insertion grooves (29) cut the outer side surfaces of the cavities (21) at the opposite ends, and the locking pieces (45) serve as side walls of the cavities (21) when the retainer (40) is mounted.

Abstract: A connector housing (10) has cavities (23) and a retainer insertion hole (27) that crosses the cavities (23). A retainer (30) can be held at a partial or full locking position in the retainer insertion hole (27). The retainer (30) has pairs of resilient locks (33) and fixed locks (35) for the corresponding cavities (23). The resilient locks (33) project into the cavities (23) when the retainer (30) is at the partial locking position while the fixed locks (35) project into the cavities,(23) when the retainer (30) is at the full locking position. The resilient locks (33) are wider than the cavities (23) and hence continue engaging the terminal fittings (10) while the retainer (30) is moved from the partial locking position to the full locking position. Thus, the terminal fittings (10) are locked doubly by the fixed locks (33) and parts of the resilient locks (33) when the retainer (30) is at the full locking position.

Abstract: The invention provides a waterproof connector in which a seal is maintained around a bolt without having to increase the number of components. A bolt 39 is passed through a through hole 36 of a bolt attachment member 35, this bolt 39 being passed from a countersunk hole 46 of a grommet 40 attached so as to cover a posterior face of a female housing 30. A nut 26 of a male housing 20 is fastened to this bolt 39, this fastening the two housings 20 and 30 together. A circular sealing member 50 is formed in a manner whereby it adjoins a central hole 47 of a base face 46A of the countersunk hole 46, a shaft 39A of the bolt 39 passing through this sealing member 50 in a manner whereby it fits tightly therewith. The sealing member 50 fits into a housing hole 53 of the bolt attachment member 35.

Abstract: To improve the sealing function of a waterproof connector provided with a collective rubber stopper. Male terminal fittings 21 at ends of electric wires 20 are pushed through electric wire through holes 33 of a collective rubber stopper 30, widening these electric wire through holes 33 while they are being pushed therethrough, and are inserted into corresponding cavities 16. Inner lips 35 of the rubber stopper 30 fit resiliently with outer circumference faces of the electric wires 20, thereby sealing each cavity 16. A ring-shaped groove 37 is formed concentrically around each electric wire through hole 33 at a posterior face of the rubber stopper 30. Inner portions of these grooves 37 form comparatively thin cylindrical members 38, these fitting tightly with the outer circumference of the electric wires 20.

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 (30) has a substantially box-shaped main body (31) with a base plate (36), first and second side plates (37, 38) projecting from the base plate (36), and outer and inner projecting plates (39, 40) projecting from the side plates (37, 38). The outer projecting plate (39) has a recess (50) for receiving a lock when the terminal fitting (30) is inserted into a cavity of a housing. The recess (50) is rectangular and an opening edge thereof is continuous over the entire periphery. A holding piece (51) projects from an edge of the inner projecting plate (40) and fits into the recess (50) for keeping the box shape of the main portion (31).

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 housing (10) has cavities (23) and a retainer insertion hole (27) that crosses the cavities (23). A retainer (30) can be held at a partial or full locking position in the retainer insertion hole (27). The retainer (30) has pairs of resilient locks (33) and fixed locks (35) for the corresponding cavities (23). The resilient locks (33) project into the cavities (23) when the retainer (30) is at the partial locking position while the fixed locks (35) project into the cavities (23) when the retainer (30) is at the full locking position. The resilient locks (33) are wider than the cavities (23) and hence continue engaging the terminal fittings (10) while the retainer (30) is moved from the partial locking position to the full locking position. Thus, the terminal fittings (10) are locked doubly by the fixed locks (33) and parts of the resilient locks (33) when the retainer (30) is at the 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 (20; 50) with cavities (23) for receiving terminal fittings (10; 60). At least a portion of each cavity (23) is rectangular and is dimensioned to receive a rectangular tube portion (11) of the terminal fitting (10; 60). At least one corner of the rectangular tube (11) defines an engaging recess (17; 61). At least one L-shaped lock (29; 51) is cantilevered forward adjacent each cavity (23) and is resiliently deflectable diagonally away from the rectangular portion of the respective cavity (23) in response to insertion of the terminal fitting (10; 60) into the respective cavity (23). The lock (29; 51) returns resiliently after proper insertion of the terminal fitting (10; 60) to engage the recess (17; 61).

Abstract: Follower pins 12 of a female housing 10 are fitted into cam grooves 35 of a lever 30 supported by axles on a male housing 20. These two housings 10 and 20 can be fitted together or separated by means of pivoting the lever 30 between a starting position, and an ending position. An upper supporting member 40 is formed at a right side of a hood 23, and a lower supporting member 44. When the lever 30 is pivoted to the starting position or the ending position, a tip thereof is supported by the supporting member 40 or 44, respectively, thereby protecting this tip from contact with other components, etc. The supporting members 40 and 44 protrude into dead space relative to the position of the housing 20. Consequently, no extra space is required when the housing 20 is placed in position, yet the lever 30 has increased length and angle of travel.

Abstract: A waterproof connector is provided with a moving support plate without requiring an increase in size of the connector. A moving plate (40) has a shape whereby a side wall (42) protrudes upwards from circumference edges of a base plate (41) having maintaining holes (44) adapted to receive tabs (24) of male terminal fittings. This moving plate (40) can be inserted in a movable manner within a hood (22) of male housing (20). A first sealing ring (51), for sealing the space between the moving plate (40) and an outer circumference face of the female housing (10), is formed on an attachment base of an inner circumference face of an anterior end (42A) of the side wall (42). A second sealing ring (52), for sealing the space between the moving plate (40) and in inner circumference face of the posterior end (42B) of the side wall (42). These sealing rings (51) and (52) are formed in a unified manner, by means of two-component molding, on the moving plate (40).

Abstract: A cover (50) is installed on a rear side of a female housing (21) of a female connector (20) to be fitted on a male connector (10). A shaft hole (73) of a lever (70) is fit on a shaft (51) that projects from a front end of the cover (50). Thus the lever (70) can be rotated around the shaft (51). The lever (70) has a cam groove (74) that engages a follower pin (17) of the male connector (10). The follower pin (17) penetrates into the cam groove 74 with the rotation of the lever (70). A lever accommodation portion (40) is formed on upper and lower walls of a female-side hood part (23). The lever (70) is accommodated in the lever accommodation portion (40), and is sandwiched between a wall (41) and an accommodation wall (42) without forming a gap therebetween. A reinforcing wall (43) connects a front end of the wall (41) and that of the accommodation wall (42) to each other.

Abstract: The invention provides a waterproof connector in which a seal is maintained around a bolt without having to increase the number of components. A bolt 39 is passed through a through hole 36 of a bolt attachment member 35, this bolt 39 being passed from a countersunk hole 46 of a grommet 40 attached so as to cover a posterior face of a female housing 30. A nut 26 of a male housing 20 is fastened to this bolt 39, this fastening the two housings 20 and 30 together. A circular sealing member 50 is formed in a manner whereby it adjoins a central hole 47 of a base face 46A of the countersunk hole 46, a shaft 39A of the bolt 39 passing through this sealing member 50 in a manner whereby it fits tightly therewith. The sealing member 50 fits into a housing hole 53 of the bolt attachment member 35.

Abstract: A rubber stopper is provided at a rear end of a housing. A receiving tool-insertion opening is formed on a bottom surface of a cavity of the housing such that the receiving tool-insertion opening is located immediately forward from the rubber stopper. A receiving portion is projectingly formed on a lower part of a pressure die. When the housing accommodating a pressure-connection terminal is placed on the lower part, the receiving portion projects upward through the receiving tool-insertion opening, and the apex of a mountain portion is located in the vicinity of an insertion hole of the rubber stopper. When a pressure tool installed on an upper part of the pressure die moves downward, a front end of an electric wire is pressed against and connected with a pressure blade. As a result, the electric wire projecting from the rubber stopper is stretched downward. In this case, a root portion of the electric wire is received with the receiving portion.
