As shown in the drawing, the second bending section 516 further includes an extending section 517 and an abutting section 518, the extending section 113 extends toward the inner wall of the side of the connection plate 511 to which the conductive sheet is connected, and the abutting section 518 is configured to abut against the inner wall of the side, transmitting the acting force and the reactive force. In order to facilitate deformation of the conductive sheet, the extension 517 extends toward the inner wall of the connection plate 511, so that a movable gap 519L is formed between the contact portion 518 and the inner wall of the connection plate 511, preferably, the movable gap 519L is smaller than or equal to 1/2H, H is the thickness of the insertion piece 52, and after the insertion piece 52 is inserted, L disappears, and the contact portion 518 contacts with the inner wall.
