Piece c is placed to face the top plate b, and a flat male terminal d is received between and in contact with the top plate b to close an electric circuit, and the locking protrusion c 1 of the elastic contact piece c is connected to the male terminal d. The connection state between the two is locked by engaging with the locking hole d1 of the two.

In order to achieve the above object, the present invention comprises an electrical contact part and a wire connection part, and the electrical contact part has a contact plate with a bent side wall on a substrate, and a contact plate with a bent side wall is provided between the substrate and the contact plate. A terminal fitting that receives a terminal fitting and is separated by a slit in the board and has a locking protrusion and a locking claw for the housing, and the locking piece is attached to the bottom wall of a terminal accommodating chamber in which the terminal fitting is accommodated. A housing is provided with a displacement allowing recess for the housing, an engaging portion for the locking pawl, and an elastic locking arm for the terminal fitting, and the terminal fitting is temporarily locked to the housing by the elastic locking arm. In this state, the lock plate engages with the mating terminal fitting while being displaced by the displacement allowing recess, and then at the final locking position where the locking claw engages with the locking part, the lock plate is not displaced. We adopted a configuration that prevents this.
