The other row of the terminal slots115penetrate through a front end of a lower surface of the insulating body1. A middle of a rear surface of the isolating wall114is recessed inward to form a fastening slot117. The fastening slot117is formed between the two rows of the terminal slots115.

Two sides of an upper portion of the insulating body1are recessed inward to form two insertion slots12extending to two tops of the two clamping grooves111. Two sides of a lower portion of the insulating body1are recessed inward to form the other two insertion slots12extending to two bottoms of the two clamping grooves111. The insertion slots12of the insulating body1are communicated with the two clamping grooves111.
