  • Publication number: 20210249819
    Abstract: A connector locking mechanism includes a housing that includes an arm having a locking member for locking on one side and a working end on the other side and a CPA member, movably built in between a non-mating position and a complete mating position, having an arm pressing projection and an inclined surface. When mating, a mating connector is inserted into a mating opening, one side of the arm swivels on the leg portion as a fulcrum by the arm pressing projection to approach the mating connector, and the locking member is locked with the locking projection. When releasing mating, the CPA member is moved to the non-mating position, the inclined surface contacts the working end of the arm, the arm swivels moving away from the housing of the mating connector, and the locking member is released from the locking projection of the mating connector.

  • Publication number: 20210167550
    Abstract: An electrical connection device includes a pair of connectors, namely a first connector and a second connector. The first connector includes a housing main body portion, a lock arm, and a cantilever portion. The second connector includes a lock receiving portion and an abutting portion. When the pair of connectors are in the unfitted state, the cantilever portion is located between the housing main body portion and the lock arm so as to be capable of supporting the lock arm. The abutting portion comes into contact with the cantilever portion when the pair of connectors are fitted together, and therefore the cantilever portion undergoes elastic displacement to a position that allows the lock arm to flex toward the housing main body portion.

  • Patent number: 10923849
    Abstract: A connector includes a housing including an accommodation passage and a retainer insertion space, and a retainer including an insertion wall extending along the connector mating direction and a locking claw protruding from a rear portion thereof toward an accommodation passage direction. In the housing, a locking protrusion is provided at a rear portion of the retainer insertion space. When the retainer is inserted into the retainer insertion space from a connector mating front side, the locking claw gets over the locking protrusion to be engaged therewith, and thus a pre-locked position at which detachment of the retainer to the front side is prevented is obtained. When the retainer is moved in a widthwise direction, a full-locked position at which the locking claw engages with a step in the rear portion of the connector terminal, and detachment of the connector terminal toward the rear side is prevented is obtained.
