  • Patent number: 11133622
    Abstract: A connector (10) includes a housing (20) and a separate connection detecting member (60). The connection detecting member (60) has a flexible and cantilevered locking lance (66). The housing (20) has a locking portion (38) with an opening and capable of locking the connection detecting member (60) by a projection (70) of the locking lance (66) coming into contact with an inner wall of the locking portion (38). The connection detecting member (60) is relatively displaceable between a connection assurance position and a connection assurance release position. When the connection detecting member (60) is displaced from the connection assurance release position to the connection assurance position, the projection (70) of the locking lance (66) slides against the inner wall of the locking portion (38) and the locking lance (66) is displaced resiliently to release the locking of the connection detecting member (60).

  • Publication number: 20210288439
    Abstract: A connector 1 includes a first housing 10 having a first lock portion 17, a second housing 50 having a second lock portion 52 to be locked to the first lock portion 17 and connectable to the first housing 10, and a CPA latch 30 relatively movable with respect to the first lock portion 17. The CPA latch 30 is movable to a release position where a locked state of the first lock portion 17 and the second lock portion 52 is releasable, a connection assurance position where a connected state of the first housing 10 and the second housing 50 is assured by the CPA latch 30 moving over a locking portion 70 of the first lock portion 17 and the second lock portion 2 from the release position, and an operation stop position where a separating operation is stopped by the CPA latch 30 being locked to the second lock portion 52 while the first housing 10 and the second housing 50 are being separated.

  • Patent number: 11114801
    Abstract: A connector (10) includes a housing (20) and a connection detecting member (60) that is displaceable between a connection assurance position and a connection assurance release position. The connection detecting member (60) is mountable on the housing (20) and pushed from a pre-assembling position to the connection assurance release position. First arms (74) are on sides of the connection detecting member (60). Two first guide grooves (44) and two second guide grooves (48) are in the side walls (42) of the housing (20) and extend along a sliding direction of the connection detecting member. First claws (76) of the first arms (74) are in the first guide grooves (44) at the connection assurance position and the connection assurance release position, and are in the second guide grooves (48) at the pre-assembling position. The first arms (74) deflect by pushing the connection detecting member (60) to the connection assurance release position.

  • Patent number: 11081835
    Abstract: A connector (10) has a wire, a rubber plug (60) fit on an outer surface of the wire and a housing 20 including a forwardly-open plug accommodating portion (22). The rubber plug (60) is sandwiched between an inner peripheral surface of the plug accommodating portion (22) and the outer surface of the wire. A retainer holds the rubber plug 60 in the plug accommodating portion (22) by being mounted on the plug accommodating portion (22) from the front. The retainer includes deflecting pieces (35) relatively displaceable with respect to the outer surface of the wire and fixing pieces (36) relatively undisplaceable with respect to the wire. The housing (20) includes push-in pieces (25) for pushing the deflecting pieces (35) into the outer surface of the wire. The wire is held in the retainer by the deflecting pieces (35) pushed into the surface of the wire and the fixing pieces (36).
