[0006] Further, lead pins are provided on the side wall of the upper installation seat, and sleeves are provided on the lead pins and are placed in the installation groove.

[0007] Further, a second conductive busbar, a third conductive busbar, a fourth conductive busbar, and a fifth conductive busbar are provided on one side of the lower installation seat, wiring nuts are provided on the second conductive busbar, the third conductive busbar, the fourth conductive busbar, and the fifth conductive busbar, and a plurality of bolts are provided on the other side of the lower installation seat.

[0008] Advantages of the Utility Model

[0009] The sealing groove is arranged inside the flange, and the sealing groove and the sealing ring are specifically designed. Then, after adding the A&B glue mixed in proportion and passing through the UV furnace for sealing, and installing the sealing ring at the same time, it can better and stably be compatible with the high-voltage power signal transmission of various different specifications of circuits, with good high-voltage high-sealing performance, effectively avoiding the risk of current and signal interference during use, and can be horizontally promoted to the designs of other similar wall-through connectors.
