Claims

[Claims for Utility Model Registration] A locking arm is provided on one side of a pair of connector housings that are fitted facing each other, and an arm locking portion is provided on the other, and when both housings are fitted, the locking arm and the arm In an electrical connector in which both housings are primarily locked by engagement with a locking portion, a locking spring is attached to one of the pair of connector housings, a locking spring locking portion is provided to the other,
The lock spring has a pair of elastic arms that extend diagonally so that the front ends close to each other, and an insertion guide that is bent outward from the distal ends of the pair of elastic arms so as to open each other. is formed as a substantially diamond-shaped protrusion with chevron-shaped slopes on both sides, and when both housings are fitted together, the lock spring engaging portion is guided by the insertion guide, opens the pair of elastic arms, and enters into the lock spring. When the housings are next locked, when the peaks of the chevrons on both sides of the lock spring locking portion are located on the outside of the pair of elastic arms, a force acts in a direction that prevents the fitting of both housings due to the repulsive force of the elastic arms. . A double locking mechanism for an electrical connector, characterized in that when reaching the inside of a pair of elastic arms, a force is applied in a direction that promotes fitting of both housings due to the elastic return force of the elastic arms.
