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 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 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 (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 (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 (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 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 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 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.

Abstract: A female housing is provided with cavities (41) into which terminal fittings are insertable, and locks (43) provided in the cavities (41) and resiliently engageable with the terminal fittings being inserted to lock the terminal fittings. Openings (64) formed by removing a mold for forming locking surfaces (58) of the locks (43) engageable with the female terminals are so formed in the female housing as to be open forward. Each lock (43) is supported at both front and rear ends, and a section thereof projecting more forward than the locking surface (58) is connected with side surfaces (64b, 64c) of the circumferential surfaces of the corresponding opening (64) extending along a deforming direction of the lock (43).

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: 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 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: Female terminal fittings (30) are insertable from behind into cavities (11) in a female housing (10). A slanted guide surface (22) is formed at the peripheral rear edge of each cavity (11) for guiding the female terminal fitting (30) into the cavity (11) and is slanted at an obtuse angle to an inserting direction of the female terminal fitting (30). A stabilizer-inserting groove (20) is formed in a surface of the cavity (11) and has an open rear end into which a stabilizer (47) of the female terminal fitting (30) is insertable. A preventing surface (27) is provided at the peripheral rear edge of the cavity (11) and abuts the stabilizer (47) when the female terminal fitting (30) is inserted in an improper posture. An angle of the preventing surface (27) to the inserting direction is less than an angle of the slanted guide surface (22).

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: The invention allows, in a connector having a moving plate provided at the anterior of a connector housing, a retainer to be attached to this connector housing from the anterior. A retainer attachment hole 17, for allowing a retainer 40 to be attached, is formed at an anterior end face of a connector housing 10. A window hole 36 is formed in a moving plate 30, at least a portion of the retainer 40 protruding towards the anterior from this window hole 36. Consequently, the retainer 40 can be pushed in, and other operations can be performed thereto, from the anterior of the moving plate 30. That is, the retainer 40 can be attached from the anterior to the connector housing 10.

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 female terminal fitting (10) has a tubular main body (11) with front and rear ends and a bottom wall (13). A fold (20) is folded back from the front end of the bottom wall (13) and a resilient contact piece (18) extends back from the fold (20) to face the bottom wall (13). A bulge (23) on the resilient contact piece (18) includes a contact (25) for contacting a tab (T) of a male terminal fitting (M). The contact (25) is pressed by the tab (T) so that the resilient contact piece (18) is deformed with the fold (20) as a supporting point and an extending end (26) thereof contacts the bottom wall (13). The resilient contact piece (18) has a front narrowed portion (29) between the fold (20) and the contact (25) and a rear narrowed portion 30 between the contact (25) and the extending end (26).
