[0006] The connection end comprises a connection head, one end of which is connected to a heat shrink tube, a mounting groove is provided inside the connection head, a sealing member is installed in the mounting groove, and a positioning groove is provided at the other end of the connection head, a terminal is installed in the positioning groove;

[0007] A limiting ring is fixedly connected inside the connecting pipe, and sealing pads are symmetrically arranged on both sides of the limiting ring.

[0008] Furthermore, the two connecting ends are both threadedly connected to the connecting pipe.

[0009] Furthermore, the sealing member comprises a sealing ring, a conical hole is provided inside the sealing ring, two convex rings are fixedly connected to the side surface, and positioning rings are symmetrically fixedly connected to both ends.

[0010] Furthermore, the terminal is a hexagonal column made of copper, and a fixing groove is opened on its side. A fixing bolt is installed in the fixing groove, and the fixing bolt is threadedly connected to the terminal.

[0011] Furthermore, the binding posts are divided into male binding posts and female binding posts.

[0012] Furthermore, the male terminal has a wiring hole at one end and a protrusion fixed at the other end; the female terminal also has a wiring hole at one end and a groove matched with the protrusion at the other end.

[0013] The advantages of the utility model compared with the existing technology are: the utility model can make the heat shrink tube stably adhere to the surface of the wire by heating the heat shrink tube, thereby fixing the connecting end and the wire, and can effectively improve the stability of the connection between the two wires when combined with the connecting tube. The setting of the seal and the sealing pad can effectively prevent external moisture from contacting the connection of the wire, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS
