The opening 13 is provided for the contact portion 21 of the conductive terminal 2 to project forward. The opening 13 includes an upper opening 131 and a lower opening 132 having a width larger than the upper opening 131 in a transverse direction. The upper end opening 131 is provided with stoppers 1311 on both lateral sides. The stop portions 1311 are formed extending from both lateral sides of the side wall 14 into the opening 13.

Referring to fig. 5 to 8, the conductive terminal 2 includes the contact portion 21 exposed out of the opening 13, the receiving portion 22 blocked inside the opening 13, the bent connection portion 24 blocked on the blocking wall 11, the U-shaped elastic portion 25 received in the receiving slot 10, and the soldering foot 26 exposed out of the rear of the receiving slot 10. The contact portion 21 protrudes in a U-shape from the opening 13. A pivoting part 23 is provided between the contact part 21 and the accommodating part 22. The receiving portion 22 is larger in lateral dimension than the pivot portion 23. The receiving portion 22 includes a flat plate portion 223 extending horizontally, a front wall 221 located at the front end of the flat plate portion 223 and stopped at the stop portion 1311, stop portions 222 located at both sides of the flat plate portion 223 and extending vertically downward and protruding from both sides of the receiving portion 22 and abutting against the stop portion 1311 to limit the contact portion 21 from protruding excessively forward, and a convex hull 2221 arranged on the stop portions 222.

The convex hull 2221 is located in the horizontal portion 2222 and the vertical portion 2223. The convex hull 2221 is provided to protrude from the stopper 222 toward both sides. Based on this design, when the contact portion 21 is pressed by the outside to deflect, the convex hull 2221 can contact the inner wall of the side wall 14 in both the horizontal direction and the vertical direction. And the contact is point contact, when the external pressing is cancelled, the conductive terminal 2 is easy to rebound. The bent connecting portion 24 connects the contact portion 21 and the U-shaped elastic portion 25.
