[0076] When the grounding socket assembly 1 and the grounding plug assembly 2 are connected, the plug 21 and the limit platform 23 must pass through the guide sleeve 13, and then the limit platform 23 and the guide sleeve 13 are restrained against each other by the rotation of the rotating shaft 22, so that the grounding socket assembly 1 and the grounding plug assembly 2 are connected, thereby realizing the line-to-ground connection, effectively preventing the grounding plug assembly 2 from being separated, and greatly improving the safety and stability of the insulating plug-in grounding device. When disassembling, the grounding socket assembly 1 and the grounding plug assembly 2 can be separated by rotating the rotating shaft 22, which is very convenient to use.

[0077] The incoming line connection assembly 11 includes an open socket 114, a connecting pipe 112, a rubber sealing sleeve 113 and an incoming line lead-in wire 111.

[0078] After the incoming lead-in wire 111 is inserted into the connecting tube 112, it is crimped with a crimping tool to complete the installation of the incoming lead-in wire 111. After installation, the incoming lead-in wire 111 and the connecting tube 112 are integrally injection molded with the rubber sealing sleeve 113, which greatly improves the safety of the grounding socket assembly 1. Preferably, the contact surface between the insulating cover 12 and the rubber sealing sleeve 113 is pre-coated with sealant, and after the connecting tube 112 and the open socket 114 are connected and tightened, the sealing insulation performance of the connection can be guaranteed.

[0079] The open socket 114 is provided with a plug-in hole 1141, into which the plug 21 is inserted, and at least one elastic opening groove is provided on the side of the open socket 114, which is connected to the plug-in hole 1141; the elastic opening groove includes a circular groove 1143 and a straight groove 1142, and the straight groove 1142 extends inward from the end of the open socket 114 in a direction away from the plug 21 and is connected to the circular groove 1143. When the plug 21 is inserted into the open socket 114, the elastic opening groove plays the role of elastic connection, realizes power connection, increases the conductive effect, and enhances the conductive performance.

[0080] The outer surface of the open socket 114 has a rotation-stopping step 1144, and the inner wall surface of the insulating cover 12 has a rotation-stopping groove 122, and the rotation-stopping step 1144 fits and matches with the rotation-stopping groove 122. When the open socket 114 is inserted into the insulating cover 12, the rotation-stopping step 1144 fits and matches with the rotation-stopping groove 122, which plays a role in positioning and rotation-stopping, so that the open socket 114 cannot rotate in the insulating cover 12, so that the grounding plug assembly 2 will not drive the rotation of the open socket 114 when rotating, and ensure that the open socket 114 will not sway or shake after being in the insulating cover 12.

[0081] The grounding socket assembly 1 also includes a rain skirt 14, which is made of silicone rubber and is injection molded.
