Above, preventing the welded portion of the first conductive terminal 21b from being deformed upward and the grounded metal piece 5b contact. In addition, the positioning posts 151b, 152b on the third insulating member 13b can position the third insulating member 13b relative to the first insulating member 11b and the second insulating member 12b. The limiting block 126b of the second insulating member 12b can position the outer shielding case 3b relative to the combined body 6b.

The above is only the embodiment of the present invention, and is not intended to limit the embodiments of the present invention. Those skilled in the art can make corresponding modifications or modifications in accordance with the main idea and spirit of the present invention. The scope shall be subject to the scope of protection required by the scope of application for patent application.
