[0042] The multiple conductive terminals 20 are all arranged on the insulating body 10, and each conductive terminal 20 has a contact portion 21 and a welding portion 22. The contact portion 21 extends into the insertion cavity 11 to contact and conduct with the cable, and the welding portion 22 extends out of the insulating body 10; in the present embodiment, the multiple conductive terminals 20 are respectively arranged and fixed in the corresponding terminal slots 16, and each contact portion 21 passes through the lateral opening of the terminal slot 16 and extends into the insertion cavity 11, and the multiple conductive terminals 20 are arranged side by side and inserted and fixed in the corresponding terminal slots 16 from bottom to top, and the assembly is stable and reliable.

[0043] The two grounding plates 30 are respectively arranged inside the two ends of the insulating body 10, and each grounding plate 30 extends an elastic hook 31 that is locked with a buckle hole on the side of the end of the cable. Specifically, the grounding plate 30 is formed by stamping a metal sheet, and the grounding plate 30 includes a base 32. The bases of the two grounding plates 32 are fixed on the insulating body 10 and respectively abut against the left and right sides of the side cover 40. The elastic hook 31 extends from the base 32. The elastic hook 31 includes a connecting section 311, an elastic section 312, a pressing section 313 and a hook head 314. The connecting section 311, the elastic section 312 and the pressing section 313 are successively integrally formed and bent and connected. The hook head 314 is buckled with the buckle hole, and the hook head 314 and the pressing section 313 surround a limit groove 301. Furthermore, a fixing portion 33 extends from the outer side of the base 32, and the fixing portion 33 is inserted from the bottom to the top into the fixing hole 15 for fixing, which has a simple structure and is easy to assemble.
