Each of the terminals 2 includes a terminal implantation section 21, a terminal fitting section 22, and a terminal connection section 23. The terminals 2 are assembled into the insulating body 1 from back to front, wherein the terminal implantation sections 21 are implanted into the terminal accommodating grooves 104, the terminal fitting sections 22 are exposed out of the insulating body 1, and the terminal connection sections 23 are correspondingly welded and fixed to the butting circuit board 30;
