Abstract: A terminal is formed by bending a plate of electrically conductive metal and is received in a connector housing. The terminal includes a box-shaped body part, a terminal contact part provided on a front side of the body part, and an electrical wire connecting part provided on a rear side of the body part. When the plate before bending is viewed from the thickness direction, a conductor section having a cross-section having constant width and thickness extends from the terminal contact part to the electrical wire connecting part.

Abstract: An upper face plate constituting a box part of a female terminal is flared outward in a free state before the female terminal is inserted in the cavity, and is formed as a spring plate that is bent and deflected inward by being pressed inward from the outside while accumulating a spring force. A stabilizer is disposed on the free end of the upper face plate. A cavity of a connector housing includes a stabilizer guide that presses back the upper face plate to the regular position by sliding on the stabilizer while the female terminal is being inserted. Accordingly, rattling of the terminal is prevented after the terminal is inserted in the cavity of the connector housing while suppressing enlargement of the outside dimensions of the terminal.

Abstract: A terminal includes a box-shaped body part including a pair of a first side wall and second side wall which are raised from both side ends of a bottom wall, a top wall extended from the first side wall, and an auxiliary wall extended from the second side wall. The top wall includes a first slit opening on a side end face of the top wall. The auxiliary wall includes a second slit opening on a side end face of the auxiliary wall. A stabilizer is formed by a portion on a front side of a separating portion formed by the second slit. A stabilizer reinforcing section is formed by a portion on a front side of a separating portion formed by the first slit. An engagement section is formed by a portion on a rear side of the separating portion formed by the first slit of the top wall.

Abstract: A connector is provided which includes a housing in which a terminal is accommodated, and a retainer which is mounted on the housing to prevent movement of the terminal in the direction of detachment. A retainer insertion hole is provided on the housing to insert the retainer, and a provisional locking projection and a final locking projection are provided which extend into the retainer insertion hole. A guide portion is provided in the retainer which is flexibly deformed by interference from the provisional locking projection and the final locking projection, and a locked portion is formed, which is a locking hole opened in the guide portion. The locked portion and the provisional locking projection are temporarily locked during the insertion process, and the locked portion and the final locking projection are locked at the end of the insertion process.

Abstract: A connector provided with a female-type metal terminal fitting, includes a case portion including a bottom plate portion, first and second side plate portions, and an upper plate portion, a lance engaging portion formed at a rear end portion of the upper plate portion so as to engage with a lance, a biasing portion integrated in the case portion, a wire connecting portion provided so as to be extended to a rear side of the case portion, and a spring supporting plate portion laminated on an inner face of the upper plate portion. A rear end portion of the spring supporting plate portion is recessed toward inside of the case portion further than the rear end portion of the upper plate portion. The biasing portion is extended from the spring supporting plate portion.

Abstract: To provide a connector in which a lance beak part will not be broken, even though a large load is applied by a front holder. A locking lance is provided, at its distal end, with a lance beak pad which is adapted to be caught by a lock releasing jig for releasing lock of the locking lance with respect to a terminal, and a locking projection which is continued from the lance beak part and erected from a terminal end of the lance beak part. When a projected part is inserted into e deflection space in a state where the locking lance is deflected, a lower face of the projected part overrides an upper face of the lance beak part, and a distal end of the projected part comes into contact with a vertical face of the locking projection which is erected from the lance beak part.

Abstract: A connector includes: a terminal including a box part which covers a terminal-contact spring, a crimped part which holds a core wire, and a concave part formed between the box part and the crimped part; and a housing integrally including an insertion port from which the terminal is inserted, an accommodation chamber in which the terminal is accommodated, an band which constitute a part of the accommodation chamber and is put into a double end-supported state so that the elastic band is pressed and elastically deformed by the box part of the terminal when the terminal is inserted in the housing from the insertion port, a lance which protrudes from an intermediate part of the band to engage the concave part of the terminal, and a reinforcement part which protrudes from the lance toward a bottom side of the housing to enter in the concave part of the terminal.

Abstract: To provide a connector in which a lance beak part will not be broken, even though a large load is applied by a front holder. A locking lance 41 is provided, at its distal end, with a lance beak part 43 which is adapted to be caught by a lock releasing jig for releasing lock of the locking lance 41 with respect to a terminal 12, and a locking projection 42 which is continued from the lance beak part 43 and erected from a terminal end of the lance beak part 43. When a projected part 51 is inserted into a deflection space 44 in a state where the locking lance 41 is deflected, a lower face 54a of the projected part 51 overrides an upper face 41c of the lance beak part 43, and a distal end of the projected part 51 comes into contact with a vertical face 41d of the locking projection 42 which is erected from the lance beak part 43.

Abstract: A terminal cover has first and second pieces (10, 30) that can be united into a tubular shape. A resilient lock piece (13) is formed on the first piece (10) and engages a lock (41) of the second piece (30) to lock the two pieces (10, 30) in a united state. The first piece (10) is formed with restrictions (17) projecting in a manner to restrict displacements of the first and second pieces (10, 30) in a resilient deforming direction of the resilient lock piece (13) by engaging the second piece (30).

Abstract: A connector (F) has a housing (10) for accommodating a terminal fitting (30) connected with wire (W). A seal (98) is mounted on the wire (W) and fits in a mounting portion (15) in the rear of the housing (10). A holder (50) is mounted on the housing (10) from behind to press the seal (98) and to prevent the seal (98) from coming out. The holder (50) has a wire insertion hole (55) for receiving the wire (W). The seal (98) has a main body (96) and a shake preventing portion (94). The main body (96) closely contacts the outer surface of the wire W and the inner surface of the mounting portion (15). The shake preventing portion (94) closely contacts the outer surface of the wire (W) and the inner surface of the wire insertion hole (55) of the holder (50).

Abstract: A connector has a housing (12) and a frame (15). The housing (12) has a wall (58) and a lock (19) that is resiliently deformable outward in the thickness direction of the wall (58). The lock (19) engages an interlocking portion (18) in the frame (15) when the housing (12) and the frame (15) are connected properly. A bracket (16) is inserted into a deformation area (62) for the lock (19) to prevent deformation of the lock (19). Thus, the lock (19) remains engaged with the interlocking portion (18) even if a force acts in a direction to separate the housing (12) and the frame (15).

Abstract: A terminal fitting (10) has a rectangular tube (13) with opposed first and second side plates (15, 16). A upper plate (17) is bent from the first side plate (15) into contact with the second side plate (16). A standing portion (23) stands up from the second side plate (16) and a pressing portion (25) is bent from the standing portion (23) and placed on the outer surface of the upper plate (17) to prevent the upper plate (17) from lifting. The pressing portion (25) is formed within a projecting range of the standing portion (23) to improve a yield of a punching operation from a metal plate.
