Figure 1 , 2 As shown in Figures 3 and 4, the shielding assembly includes a contact 1, a cable 4, an insulating member 2 and the shielding member. The connection relationship between the contact 1, the cable 4 and the insulating member 2 can be realized by using the existing technology. Specifically, one end of the contact 1 is a plug-in end and the other end is a wiring end. The cable 4 is crimped to the wiring end of the contact 1. The insulating member 2 is coated on the outside of the contact 1. Locking holes are provided on the opposite sides of the insulating member 2. A first opening and closing structure 21 rotatably provided on the insulating member 2 is provided at one end of the locking hole.
