  • Patent number: 11201433
    Abstract: A lever-type connector (10) includes wires (24), a housing (14), a cover (32), a lever (16) and a binding band (44). The lever (16) is mounted on the housing (14) for rotation between connection start and connection end positions. The cover (32) includes a wire draw-out portion (34) for bending the wires (24) pulled from the housing (14) and a wire fixing portion (36) for fixing the wires (24) to the wire draw-out portion (34). The wire fixing portion (36) includes a first side wall (38) on an inner side, a second side wall (40) on an outer side and a bottom wall (42) between the first and second side walls (38, 40). Contact of the lever (16) with the second side wall (40) stops rotation at the connection start position. The bottom wall (42) includes two band insertion holes (46) through which the binding band (44) is inserted.

  • Patent number: 11139608
    Abstract: A connector is provided with a body cover and a lid cover for covering a wire. A tightening member is to be wound along a surface of the body cover. A first part and a second part are provided on the surface of the body cover while being spaced apart in a circumferential direction. A recess is provided between the first and second parts in the body cover, and a pressing portion is stretched from the first part toward the second part in the tightening member. A coupling is to be received into the recess in the lid cover, and a pressed portion is arranged outwardly of a virtual straight line connecting the first and second parts in the coupling. The pressing portion presses the pressed portion toward an inner surface of the recess.

  • Patent number: 9698514
    Abstract: A connector (10) includes a female housing (20) for accommodating female terminals (24) and a retainer (40) mountable in female housing (20). The retainer (40) includes a retaining portion (41) that retains the female terminals (24) by being inserted into a retainer mounting hole (27) in the female housing (20). Locks (46) are adjacent to the retaining portion (41) in a direction intersecting an inserting direction of the retaining portion (41) while standing up from bases (45) integral to the retaining portion (41). The locks (46) resiliently deform by moving onto partial locking projections (30) and full locking projections (31) formed in the female housing (20), and resiliently restore to engage the partial locking projections (30) and the full locking projections (31). The lock pieces (46) are separated from the retaining portion (41).

  • Patent number: 9543697
    Abstract: A connector has a slider (60) with a base (61) extending along a width direction and to be inserted below a lock arm (17). Two arms (62) project from opposite widthwise ends of the base (61). A coupling (63) couples projecting end parts of the arms (62) and faces an upper surface side of the lock arm (17). A deflectable initial position holding portion (76) is provided on the base (61) and is configured to regulate a movement of the slider (60) to a connection position by resiliently locking an initial position holding receiving portion (25) of a housing main body (11) at an initial position. A connection position holding portion (64) is provided on the coupling (63) and is configured to regulate a detachment of the slider (60) by contacting a connection position holding receiving portion (23) of the lock arm (17) at the connection position.

  • Patent number: 9515410
    Abstract: In the process of connecting first and second housings (10, 90), a slider (60) is kept at an advanced position by locking a resilient stopper (76) and a stopper receiving portion (25), and springs (80) accumulate spring forces. The resilient stopper (76) and the stopper receiving portion (25) are released as the housings (10, 90) are connected and the slider (60) is moved to a retracted position while being biased by the springs (80). The resilient stopper (76) projects from a base end (52) to a tip (51) and has a first support (54) at the base end (52) to function as a support of deflection when starting deflection in the process of connecting the first and second housings (10, 90) and a second support (58) closer to the tip (51) than the base end (52) to function as a support of deflection following the first support (54).

  • Patent number: 9484684
    Abstract: A connector includes a first housing (10) with a terminal accommodating portion (11) surrounded by a peripheral wall (17), a second housing (60) connectable to the first housing (10), and a detector (40) to detect a connected state of the housings (10, 60) based on whether the detector (40) moves from an initial position to a detection position in a space between the terminal accommodating portion (11) and the peripheral wall (17). An opening (22) extends circumferentially in a part of the peripheral wall (17) and exposes the detector (40). Deformation regulating portions (23, 53) are formed on the peripheral wall (17) and the detector member (40) and permit movements of the detector (40) between the initial position and the detection position and regulate deformation of the peripheral wall (17) to enlarge an opening width of the opening (22) by being fit to each other.
