[0051] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0052] When in use, firstly, the second bolt 18 is screwed off, and the upper insulating shell 2 is removed from the top of the lower insulating shell 1, and the fixed connection between the upper positioning block 5 and the lower positioning block 4 is released, and the upper positioning block 5 is temporarily separated from the top of the lower positioning block 4;

[0053] Then, the insulation layer of the butt-joined ends of the connecting cable 6 and the overhead composite cable 7 to be butt-joined is stripped, and then the butt-joined ends of the connecting cable 6 and the overhead composite cable 7 are respectively passed through the lower positioning block 4 and the annular core sealing plate 801 and the inside of the insulating transparent hard tube 3, and the butt-joined ends are made to contact, and then the upper positioning block 5 is engaged with the top of the lower positioning block 4, and fixedly connected with the first bolt 15, the lower positioning block 4 and the upper positioning block 5 are fixedly connected, and the threaded grooves 12 on the inner walls of the lower positioning block 4 and the upper positioning block 5 will tightly bind the surfaces of the insulation layers of the connecting cable 6 and the overhead composite cable 7;

The annular sealing plate 801 moves and the annular sealing plate 801 also drives the inner cone cover 906 to move, and causes the inner cone cover 906 to move to the inside of the insulating transparent rigid tube 3. The inner cone cover 906 moves horizontally, and the movable rod 905 that contacts the inclined surface of the inner cone cover 906 is continuously squeezed and displaced. The movement of the movable rod 905 synchronously drives the arc-shaped clamping plates 904 to move. Several arc-shaped clamping plates 904 shrink in an annular shape to centrally clamp the connecting cable 6 and the overhead composite cable 7, so that the butt ends are relatively and completely in direct contact.

[0056] Finally, fill the inside of the insulating transparent hard tube 3 with 704 glue through the glue injection hole 30.
