Patent number: 9197015Abstract: A connector includes a spring portion, a lock member and a movable member. When the movable member is forced to be moved from a non-operation position to an operation position, an operation portion of the movable member operates an operated portion of the lock member to move a lock portion of the lock member from a lock position to an unlock position. When the movable member is held at the operation position, a front end of the spring portion presses a pressed portion of the movable member to move the movable member towards the non-operation position. When the movable member is released, the movable member is moved back from the operation position to the non-operation position so that the operation portion stops to operate the operated portion to move the lock portion back to the lock position.Type: GrantFiled: December 13, 2013Date of Patent: November 24, 2015Assignee: Japan Aviation Electronics Industry, LimitedInventors: Yukitaka Tanaka, Chikara Kawamura
