2. The ground terminal guard of claim 1, further comprising a first closing-in sleeve, one end of the first closing-in sleeve being in communication with the mounting port, the other end of the first closing-in sleeve being configured to allow at least a portion of the ground terminal to pass into the receiving cavity; the first binding off sleeve pipe is close to be provided with the opening on the lateral wall of installing port one end, just the opening with the socket joint intercommunication becomes integrative, the opening makes the protective housing can round protective housing with first binding off sheathed tube junction rotates.

3. The ground terminal guard of claim 2, further comprising a second closing-in sleeve, wherein one end of the second closing-in sleeve is in communication with one end of the first closing-in sleeve away from the mounting opening, the other end of the second closing-in sleeve is used for a wire harness to pass out, a bending opening is formed in a side wall of the second closing-in sleeve, which is close to the first closing-in sleeve, and the bending opening enables the second closing-in sleeve to be bent at the bending opening.

4. The bonding terminal protection device according to claim 3, further comprising a glue winding fixing strip, wherein one end of the glue winding fixing strip is arranged at one end of the second closing sleeve far away from the first closing sleeve, and the other end of the glue winding fixing strip is provided with a glue stopping protrusion.

5. The ground terminal guard of claim 4, wherein the diameter of the second sleeve decreases in sequence from an end of the second sleeve proximate the first sleeve toward an end of the second sleeve distal the first sleeve.

6. The ground terminal shield of claim 5 wherein a reinforcing rib is provided at a junction of said shield shell and said first crimp sleeve.

7. The ground terminal guard of any one of claims 3 to 6, wherein the socket, the opening and the bent opening are all on the same side, and a projection of the socket toward the receiving cavity is located in the receiving cavity; the projection of the notch towards the first closing-in sleeve is positioned in the first closing-in sleeve; and the projection of the bending opening towards the second closing-in sleeve is positioned in the second closing-in sleeve.

8. The ground terminal shield of any one of claims 4-6 wherein said shield shell, said first closing-in sleeve, said second closing-in sleeve, and said glue-wrap securing strip are integrally formed.

9. The ground terminal guard of any one of claims 1 to 6, wherein a second clamping groove and a third clamping groove are further disposed in the accommodating cavity, the second clamping groove and the third clamping groove are located on two opposite sides of the first clamping groove, the second clamping groove is used for clamping the first insulating baffle of the ground mounting seat, and the third clamping groove is used for clamping the second insulating baffle of the ground mounting seat.

10. The ground terminal guard of any one of claims 1 to 6, wherein the socket has a shape that matches the shape of the ground mount.
