Abstract: A retainer inserted from one side face of a housing is equipped with projections which penetrate from the side of hooked grooves of female terminal fittings, and insert portions which penetrate into bending spaces of lances from the side. When female terminal fittings are partially inserted into chambers of the housing, the insert portions of the retainer contact against the side faces of lances which are bent into the bending spaces, and the projections contact against the side face of connecting parts of the female terminal fittings. Further movement of the retainer is prevented and the partial insertion is detected. When the retainer is properly inserted, the projections are fit on the hooked grooves to be directly locked, and the insert portions are inserted in the bending spaces to prevent bending of the lances to be indirectly locked. Therefore, the female terminal fittings are triply and strongly locked, including the hooking of the barb parts of the terminal fittings by the lances.

Each terminal fitting (10) has a lock engaging projection (17) for engaging a lock (22) of the housing (20). Each terminal fitting (10) also has a step (14) and a retainer engaging projection (15) formed continuously with the step (14). The lock engaging projection (17) interferes with a lock (46) of a retainer (40) that is being displaced to a full locking position even if the female terminal fitting (10) is left lightly inserted without reaching the position where the retainer engaging projection (15) interferes with the locking projection (46). Thus, an insufficient insertion can be detected even when the female terminal fitting (10) is left even more lightly inserted.

Abstract: A TPA (terminal position assurance) and CPA (connector position assurance) combining structure for a connector in a vehicle wiring system connector set. The TPA/CPA combining structure is a CTPA (connector/terminal position assurance) member movably mounted on a specially formed connector latch on the first connector's housing between TPA preset, TPA set/CPA preset, and CPA set positions. The CTPA member responds to a complete terminal installation in the first connector housing by becoming movable from TPA preset to TPA set, externally verifying terminal installation and securing a terminal latching member on the housing from unintended release. The TPA set position is also a CPA preset position in which the TPA-assured first connector is ready to receive a mating connector, a portion of which releases the CTPA member from CPA preset to allow movement to a final CPA set condition verifying full connector mating.

Abstract: A connector has means for preventing terminal fittings from being inserted in an inverted manner, and in which nothing protrudes from outer faces of these terminal fittings. Cut-away portions 17 are formed at a ceiling side of anterior ends of left and right side plates 11B of a box-shaped member 11 of a terminal fitting 10. Protrusions 34 are formed within a cavity 24 at anterior ends of left and right wall faces thereof, in locations somewhat removed from a wall face having a lance 26 formed thereon. These protrusions 34 are capable of fitting into the cut-away portions 17. When the terminal fitting 10 is correctly inserted, the protrusions 34 fit into the cut-away portions 17, and the terminal fitting 10 is pushed into a correct position and is retained by the lance 26. When the terminal fitting 10 is inserted in an inverted manner, the anterior end of the box-shaped member 11 strikes against the protrusions 34 before the terminal fitting 10 reaches the correct position.

Abstract: A connector (F) includes two partial locks (41) for holding a terminal retainer (15) in a partial locking position with respect to a housing (Fh) and two full locks (42) for holding the terminal retainer (15) in a full locking position.

The partial locks (41) are on opposite sides of the housing (Fh) and are spaced longitudinally. Similarly, the full locks (42) are on opposite sides of the housing (Fh) and are spaced apart longitudinally. The spaced disposition of the locks (41, 42) stabilizes the retainer (15) in response to forces exerted longitudinally of the terminal fittings (5).

Abstract: Male and female connector housings 10 and 20 are latched in a fitted state by a locking arm 40 engaging with a stopping member 16. An upper face of an operating member 44 at a posterior end of the locking arm 40 forms an inclined face 50, this face 50 being inclined gradually downwards towards the anterior. An anterior end of the inclined face 50 rises abruptly upwards, forming a counteracting wall 51. In the case where the two housings 10 and 20 are to be separated, a finger F presses the operating member 44, causing the locking arm 40 to incline and release the lock. The upper face of the operating member 44 is concave, with the contacting wall 51 at its anterior end. Consequently, the location for placing the finger F during the pressing operation is clearly defined, and the finger is prevented from sliding forwards during the pressing operation. As a result, the pressing operation of the operating member 44, that is, the lock-releasing operation, can be performed smoothly.

Abstract: An electrical connector assembly including a housing accommodating electrical terminals, a structure for locking each electrical terminal inside of the housing, a lid, a structure for maintaining the terminals in place including a locking body, and a structure for fixing the lid and the housing. The housing includes holes accommodating the electrical terminals and on which a structure for coupling the lid to the housing is included, so that there is a separation between the lid and the housing thereby allowing the wiring to pass to an outside through opposing ends of the lid. The locking body includes flanges that extend inside the housing, and mount the locking body inside the housing in a first position in which the locking body is partially outside of the housing. The flanges allow the locking body to be located at a second position where the locking body is placed completely inside the housing.

Abstract: A connector is provided, which includes a connector housing and a front holder, wherein the connector housing has an insertion slot for receiving the front holder therein, a terminal receiving chamber for receiving the terminal therein, and a resilient locking arm which is resiliently deformed when pushed by the terminal and is resiliently recovered when the terminal is fully inserted into the terminal receiving chamber. The resilient locking arm has a detection end which is lowered toward the insertion slot when the resilient locking arm is resiliently deformed and is lifted toward the terminal receiving chamber when the resilient locking arm is recovered. The front holder has a holder end facing the detection end, and a stopper which stops the front holder at a provisional locking position where the holder end is spaced apart from the detection end and is pushed into the insertion slot when the front holder passes through the provisional locking position.

Abstract: A male housing (10) has a receptacle (12) that surrounds a tower (11) provided with cavities (13). A retainer (20) is mounted on the front of the tower (11). The bottom surface of the retainer (20) has a longitudinal groove (41) with a catch surface (42), and a jig insertion groove (40) is formed in a bulging portion (22) at the bottom end of the rear surface of the retainer (20). An upwardly sloped guide surface (51) is formed in the bottom surface of the receptacle (12) and aligns with the jig insertion groove (40). A jig (45) having a hook (47) at one end is provided to detach the retainer (20). The hook (47) of the jig (45) is inserted through the jig insertion groove (40) and moves up along the guide surface (51) to enter the longitudinal groove (41) and face the catch surface (42). The jig (45) then is pulled back to detach the retainer (20).

Abstract: A horizontally inserted retainer is mounted in a housing, and can be moved between a temporary locked position which allows insertion and removal of female terminal fittings and a final locked position which retains the female terminal fittings in the housing. A front stop plate with insertion openings is provided on the retainer, and the insertion openings are offset from housing chambers containing female terminal fittings when the retainer is in the temporary locked position. A continuity test is carried out by inserting a test probe through the insertion openings when the retainer is in the temporary locked position. Since only a portion of the front rim of the female terminal fitting is accessible through the insertion opening, the test probe contacts the portion of the front rim and does not enter deeply into the female terminal fitting.
