Abstract: A rectangular tube (10) of a terminal fitting (T) includes a lid plate (16) extending substantially at a right angle from the extending end of a right side plate (15) and formed with a locking hole (20) extending over the entire width. A front plate (19F) is cantilevered from the right side plate (15) and arranged before the locking hole (20). A rear plate (19R) is cantilevered from the right side plate independently of the front plate (19F) and is behind and adjacent to the locking hole (20). A retracted portion (21) is formed over the entire width at the rear plate (19R), retracted inwardly of the rectangular tube (10) from the front plate (19F) to provide a height difference within the range of an engagement margin with a locking projection (34) and capable of facing a rear end of the locking projection (34).

Abstract: A terminal fitting (T) includes a locking plate (19) extending from a first side plate (17) and a stabilizer (22) projecting from a second side plate (18). A cutout (35) is formed at the extending end edge of the locking plate (19) and engages the stabilizer (22) to restrict relative displacements of the locking plate (19) and the second side plate (18) to define a first linking portion (27) that links the base plate (16) and a first contact piece (23). A second linking portion (28) links the second side plate (18) and a second contact piece (24). A restricting portion (36) is formed on the locking plate (19) and restricts displacement of the second contact piece (24) away from the first plate-like contact piece (23).

Abstract: It is aimed not to increase contact resistance between a wire and a wire crimping portion even upon being subjected to a thermal cycle. A gold plating layer is formed on a base metal (20) via a nickel plating layer (21) in a terminal contact portion (11) to be held in contact with a mating terminal. A tin plating layer (23) is formed on the base metal (20) without via the nickel plating layer (21) in a wire crimping portion (12) to be crimped and connected to a core (15) of an insulated wire (14).

Abstract: Rear engageable surfaces (16B) of engageable portions (16) face communicating portions (37) and are inclined to produce forces for pushing another housing (11) forward in a connecting direction with one housing (21) upon receiving resilient restoring forces of leg portions (51) when a pair of connectors (10, 20) reach a properly connected state. A fitting portion (27) of the second connector (20) is formed with slanted surfaces (46) inclined to reduce the width of the fitting portion (27) toward the back side of the fitting portion (27). The slanted surfaces 46 and the first connector (10) are set to come into contact at a position where a clearance is defined before the first connector (10) in the connecting direction with the second connector (20).

Abstract: A object of the present invention is to enable a double-locking of female terminals without making a whole connector larger in size or complicating a structure thereof while maintaining fine waterproof function. A female connector C1 includes a female housing 12 for retaining a female terminal 10 and a seal member holder 16. The seal member holder 16 retains a seal member 14 having through holes 14a. When the seal member holder 16 is completely attached to the female housing 12, the seal member 14 comes in close contact with a front surface of the female housing 12. In this state, a male terminal 20 of a male connector C2 fits into the female terminal 10 so that a projecting portion 25 of the connector C1 comes in close contact with an inner surface of the through hole 14a to make terminals waterproof individually.

Abstract: A female connector (F) is provided with an outer housing (10) in the form of a bottomed tube, a spring member (50) to be accommodated in the outer housing (10), and an inner housing (30) to be accommodated in the outer housing (10) to sandwich the spring member (50) between the inner housing (30) and a back wall (12) of the outer housing (10) and adapted to hold female terminal fittings (80). The inner housing (30) is pushed by a male connector (M) to move toward the back wall (12) and is floating-supported between the back wall (12) and the male connector (M) via the spring member (50) to move in connecting directions when the male connector (M) is fitted into the outer housing (10) to be locked therein. Upon an occurrence of vibration, the inner housing (30) is capable of moving while following movements of the outer housing (10).

Abstract: A cover (20) has opposed halves (21) with butting walls (28). An engaging projection (27) is formed in an accommodation concavity (30) rearward from an edge (29) of the butting wall (28). A portion between the engaging projection (27) and the edge (29A) on a bottom surface of the accommodation concavity (30) defines a temporary holding surface (32) which is contacted by a connection portion (26B) of a locking arm (26) on the opposed half (21). The temporary holding surface (32) stabilizes the posture of each half (21) before the locking arm (26) rides over the engaging projection (27). Thus, halves (21) do not incline and the connection operation is accomplished smoothly.

Abstract: One 20 of a pair of connector housings 10, 20 connectable with each other is provided with a slider 40. The other connector housing 10 is provided with main follower pins 17 and auxiliary follower pins 18 located at different positions from the main follower pins 17. The slider 40 is formed with main cam grooves 44 for guiding the main follower pins 17 until the connection of the two connector housings 10, 20 is completed and auxiliary cam grooves 48 engageable with the auxiliary follower pins 18 at a desired timing within a period from an intermediate stage of the connection of the two connector housings 10, 20 to a completing timing of the connection.

Abstract: An attempt to fit an improper combination of housings (10, 30) together brings a projection (32R) of the wrong housing (30) into abutting engagement with an interference portion (15) in a fitting recess (12). Abutment surfaces (15a, 32Ra) are inclined in directions to move an inner peripheral surface of the fitting recess (12) towards an outer peripheral surface of the wrong housing (30). Therefore, the fitting recess (12) cannot deform and spread out, and the fitting of the wrong housing (30) cannot proceed by force.

Abstract: A connector includes a housing (130) with a cavity (131) and a lock (133) that is resiliently deformable along a deformation direction (DD). A terminal fitting (110) is insertable into and withdrawable from the cavity (131) along inserting and withdrawing directions (IWD) and is configured to be locked by the lock (133). A jig (160) can be slid linearly into a jig insertion space (148) between the terminal fitting (110) and the lock (133) for disengaging the lock (133) from the terminal fitting (110).
