The terminal base 2 is provided with a plurality of signal terminals and a plurality of signal terminals. A plurality of conductive terminals 21 formed by grounding terminals, and one side of the terminal base 2 is bent downward to form a plurality of buckle blocks 22 that can be buckled to the positioning grooves 10, and at least one side of the buckle blocks 22 is formed with A resisting block 23 abuts against the concave wall 13, and between the adjacent buckle blocks 22 or the resisting blocks 23, each recess is provided for the abutting protrusions 14 to extend into abutting a proximity groove twenty four.
