As a preferred embodiment, the outer surface of the plastic body corresponds to the second connection end setting of the ground terminal There is terminal groove, the second connection end is contained in terminal groove.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Scheme is understood：

By the way that the first connecting pin of ground terminal is electrically connected on pcb board, second connection end is covered on the plastic cement External surface；The shielding shell is coated on outside plastic body, and the shielding shell corresponds to and screw hole is offered at second connection end；Institute Screw-driving is stated in screw hole and being crimped in the second connection end of the ground terminal, the ground terminal is through screw and screen Cover shell electric connection；In this way, the earthing mode for efficiently solving existing cable connector is complicated, occupied space is big and It is electrically connected insecure problem.

More clearly to illustrate the architectural feature of the utility model and effect, come below in conjunction with the accompanying drawings with specific embodiment pair The utility model is described in detail.
