型化が図れる利点もある。 As described above, the present invention comprises: an earth terminal plate disposed on the surface of a cover that adheres to the opening of the body of an electrical device; a lead plate connected to the earth terminal plate and provided on the back surface of the cover; It comprises an inner frame in which a guide hole is bored, and a ground terminal plate arranged on the back side of the inner frame.
A substantially L-shaped contact spring piece is formed to extend from one side end of the lead plate so as to be arranged in parallel with the lead plate, and when the cover is attached to the body, the free end of this contact spring piece is attached to the middle frame. The contact spring piece is loosely inserted into the guide hole from the front side of the inner frame, and the end surface of the free end of the contact spring piece is pressed and slid against the surface of the inner frame of the ground terminal plate facing the guide hole to make elastic contact. By loosely inserting the free end of the spring piece into the guide hole of the middle frame arranged inside the body from the front side of the middle frame, when the body and cover are attached, the free end of the spring piece can be connected to the ground terminal board. In addition, by bringing the end surface of the free end of the contact spring piece into elastic contact with the surface of the ground terminal plate by pressurizing it, the surface of the ground terminal plate can be brought into contact with the end face of the free end of the contact spring piece. This cleans the surface of the ground terminal board, allowing a reliable connection between the ground terminal board and the lead plate. By forming the letter-shaped contact spring pieces to extend, the storage space can be made smaller than in the conventional case where the contact spring pieces are made to protrude from the lead plate. Another advantage is that it can be made smaller.
