A first groove 13 and a second groove 14 extending in the longitudinal direction are respectively provided on two lateral sides of the top surface of the insulating body 10. The first folded portion 417 and the second folded portion 427 are respectively locked in the first groove 13 and the second groove 14. The first folded portion 417 and the second folded portion 427 have a C-shaped structure. Referring to the sixth figure, the bottom edges of the first long wall 41 and the second long wall 42 are respectively provided with a first hook 418 and a second hook 428 bent inwardly. The first hook 418 and the second hook 428 are respectively fixed to two sides of the bottom of the insulating body 10 by riveting. The metal casing 40 is fixed to the insulating body 10 by the first and second folded portions 417 and 427 and the first and second hooks 418 and 428. Referring to the seventh figure, the metal casing 40 further includes a connecting portion 43 connected to the first and second long walls 41 and 42. A top surface of the insulating body 10 is provided with a receiving groove 15 extending in the lateral direction. The connecting portion 43 is received in the receiving groove 15. The insulating body 10 is further provided with a protruding portion 16 protruding into the receiving groove 15, and the protruding portion 16 clamps the connection portion 43 so as to prevent the metal casing 40 from shaking.
