Multiple groups of first wire structures 2 are fixedly connected to the side surface of the connector 1. The first wire structure 2 includes an insulating sleeve 21, a winding layer 22, a connection block 23, a connection card slot 24, a heat dissipation through hole 25, and multiple groups of second wire structures 3. The connection block 23 is arranged between multiple groups of second wire structures 3. Multiple groups of second wire structures 3 are twisted together. The winding layer 22 is wound on the outside of multiple groups of second wire structures 3. The insulating sleeve 21 is sleeved on the surface of the winding layer 22. The connection card slot 24 is opened on the side surface of the connection block 23. The second wire structure 3 is stuck inside the connection card slot 24. The heat dissipation through hole 25 is opened in the middle of the connection block 23.

[0034] Among them, during use, multiple groups of second wire structures 3 are stranded on the surface of the connection block 23, and the second wire structures 3 are stuck inside the connection card slots 24. At the same time, according to the number of stranded second wire structures 3, a connection block 23 with a corresponding number of connection card slots 24 can be used. The connection block 23 supports the second wire structures 3, improves the stability of the second wire structures 3, and at the same time prevents the second wire structures 3 from directly contacting each other, reducing the influence of the heat generated during the transmission of the second wire structures 3 on other second wire structures 3 and improving the transmission safety of the second wire structures 3.

[0035] In addition, a winding layer 22 is wound around the surface of multiple groups of second wire structures 3 to tightly fix the second wire structures 3 on the surface of the connection block 23. Then, an insulating sleeve 21 is coated on the surface of the winding layer 22 to improve the safety of cable use.

[0036] Participate Figure 4 and Figure 5 Moreover, the second wire structure 3 includes a metal strip 31, a heat - melt mylar 32, an insulating tape 33, and copper wires 34. There are two groups of copper wires 34, and each group of copper wires 34 is stranded by single - strand or multi - strand. The insulating tapes 33 are respectively coated on the surfaces of the two groups of copper wires 34, and the two groups of insulating tapes 33 are stranded together. The heat - melt mylar 32 is coated on the outside of the two groups of insulating tapes 33, and the metal strip 31 is coated on the surface of the heat - melt mylar 32. The cable sealant 35 is filled in the gaps where the insulating tapes 33 are stranded.

[0037] Specifically, the insulating tape 33 is pressed on the surface of the copper wire 34 to protect the copper wire 34. Then, the two groups of copper wires 34 with insulating tapes 33 are stranded together, and then the cable sealant 35 is filled in the stranded gaps to improve the sealing, insulation, weather resistance, flame retardancy, and wear resistance of the copper wire 34. Then, the heat - melt mylar 32 is coated on the surface of the cable sealant 35, and then the metal strip 31 is coated on the surface of the heat - melt mylar 32. The metal strip 31 reduces the resonance problem caused by cable attenuation and improves the transmission stability of the cable.

[0038] The working principle of the present utility model: To facilitate the long - distance transmission of the cable and ensure the stability during the transmission process, two groups of copper wires 34 with insulating tapes 33 are stranded together, then the cable sealant 35 is filled in the stranded gaps, then the heat - melt mylar 32 is coated on the surface of the cable sealant 35, and then the metal strip 31 is coated on the surface of the heat - melt mylar 32. The metal strip 31 reduces the resonance problem caused by cable attenuation and improves the transmission stability of the cable. At the same time, by stranding the second wire structures 3 on the surface of the connection block 23, direct contact between multiple groups of second wire structures 3 is avoided, the safety of the metal strip 31 is improved, and at the same time, the heat dissipation capacity of the cable is improved.
