The first frame 313 defines the flat plate portion 31 attached to the two longitudinal ends of the side wall 11, and the second frame 314 connects the two ends of the two first frames 313. The first frame 313 is attached to the top surface of the sidewall 11. The first holding portion 311 continues to extend downward and penetrates through the bottom surface of the insulating housing 1, so as to form a first pin 312, and the first holding portion 311 and the first pin 312 are not on the same vertical plane. The second frame 314 is partially embedded in the end wall 12, and the first holding portion 311 is formed by bending and extending downward from the inner edge of the second frame 314.

The insulating body 1 is provided with a key portion 14 connected between the two side walls 11. The metal frame 3 is provided with a key plate 34 attached to the top surface of the key portion 14. The key plate 34 extends downward from its side edge to form a second holding portion 341, and the second holding portion 341 is attached to the side surface of the key portion 14. The second holding portion 341 continues to extend downward and penetrates through the bottom surface of the insulating housing 1, so as to form a second pin 342, and the second holding portion 341 and the second pin 342 are not on the same vertical plane. In this embodiment, the second holding portion 341 extends downward from one side edge of the key plate 34, and the other side edge is not provided with the second holding portion attached to the side surface of the key portion 14.
