The two grounding legs 52b are extended, and the two grounding legs 52b can be soldered to a circuit board, so that the grounding metal piece 5b can be further provided with an additional grounding circuit.

The above is only a preferred 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 a very convenient manner according to the main idea and spirit of the present invention. The scope of protection shall be subject to the scope of protection required by the scope of application for patents.
