The bottom wall 621 is provided with a limiting abutting portion 6211 protruding from the upper cover casing 61. The second sidewall 622 is provided with a latching hole 6221 corresponding to the latching projection 6121 of the first sidewall 612. The second positioning latching portion 624 is provided with a through hole 625 at a position connecting the bottom wall 621. After the metal casing and the mask casing are assembled, the buckle boss 6121 and the snap hole 6221 are mutually engaged to achieve stable assembly of the upper mask casing 61 and the lower mask casing 62. The first positioning latching portion 614 and the second positioning latching portion 624 are engaged with the front end surface of the insulative housing 1 , and the locking piece 55 of the metal housing 5 is engaged with the second fixed positioning portion 624 through the through hole 625 . The limit resisting portion 6211 is pressed against the rib 44 below the insulating base 4. Therefore, the insulative housing 1, the insulating base 4, the metal outer casing 5, and the mask housing 6 are stably held. Due to the outward resilience, the grounding spring 54 is in stable contact with the upper mask housing 61, achieving a reliable electrical connection. [0024] Since the grounding elastic piece 54 extends obliquely outward at a certain angle, after the metal casing and the mask casing are assembled, the grounding elastic piece 54 is pressed by the upper mask casing 61 and received in the recessed portion 111. The grounding spring 54 will ensure stable contact with the upper mask housing 61 under the effect of the outward resilience. Therefore, the problem that the metal casing 5 and the mask casing 6 are poorly conducted will be better improved.
