  • Patent number: 10559923
    Abstract: An electrical connection device includes a first connector (C1) having a first housing (10), a second connector (C2) having a second housing (20) for receiving the insertion of the first housing (10), and a connection detecting tool (30). The first housing (10) includes a housing body (12), a lock (14) having a tool restraining portion (14d) and a displacement restricting portion (16) for blocking an insertion allowing displacement of the lock (14). The connection detecting tool (30) is held at an operating position to resiliently deform the displacement restricting portion (16) to allow the insertion allowing displacement. The tool restraining portion (14d) restrains the connection detecting tool (30) at the operating position so as not to be separable while allowing the separation of the connection detecting tool (30) from the operating position as the lock (14) resiliently returns to a lock position.

  • Publication number: 20200044379
    Abstract: A connector includes a housing (10) having a terminal accommodation chamber (11) formed therein, and a first terminal fitting (12) can be inserted into the terminal accommodation chamber (11). A retainer (20) can be assembled to the housing (10) at a temporary locking position and at a final locking position, and a terminal holding member (30) can be assembled to the housing (10). A second terminal fitting (40) is attached to the terminal holding member (30). Interference parts (24, 26) are formed in the retainer (20) and the terminal holding member (30), respectively. The interference parts do not interfere with each other when the retainer (20) is in the final locking position. However, the interference parts interfere with each other to prevent the terminal holding member (30) from being assembled to the housing (10) when the retainer (20) is in the temporary locking position.

  • Patent number: 10476193
    Abstract: It is aimed to detect a mounted state of a second terminal fitting in a terminal unit in which the second terminal fitting is mounted in a terminal holding member. A connector includes an interfering projection (25) formed on a retainer (21). When a second terminal fitting (50) of a terminal unit (30) is properly mounted in a terminal holding member (31), the retainer (21) is displaceable from a partial locking position to a full locking position without the interfering projection (25) interfering with the second terminal fitting (50). When the second terminal fitting (50) is improperly mounted in the terminal holding member (31), the interfering projection (25) interferes with the second terminal fitting (50), thereby restricting a displacement of the retainer (21) to a full locking position.
