Description

Technical Field

[0001] The utility model relates to the technical field of connecting wires, in particular to a connecting wire that is resistant to high temperature rupture. Background Art

[0002] With the rapid development of modern society and the continuous advancement of science and technology, people are paying more and more attention to the safety issues of various electronic products, and the quality and functional requirements of electronic products are also getting higher and higher. The importance of connecting cables as a carrier for data and power exchange between devices, devices and machines, and machines and machines is self-evident.

[0003] The connecting wire is an important carrier for data and power exchange and has a wide range of applications. However, when the existing connecting wire is in a high temperature environment, the external high temperature plus the temperature generated by the connecting wire itself will cause the overall heating of the connecting wire to be serious and easy to break, thereby shortening the service life of the connecting wire. Therefore, a connecting wire that resists high temperature breakage is urgently needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a high temperature rupture resistant connecting wire in order to solve the problems that the existing connecting wires generate heat seriously and are easy to rupture when in a high temperature environment, thereby shortening the service life.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: it includes four wire cores, each of which is wrapped with an insulating layer on the outside, a metal shielding layer is arranged on the outside of the insulating layer, a heat dissipation filler is arranged between the metal shielding layer and the insulating layer, a heat dissipation layer is arranged on the outside of the metal shielding layer, a flame retardant layer is arranged on the outside of the heat dissipation layer, an anti-rupture reinforcement layer is arranged on the outside of the flame retardant layer, a water-blocking layer is arranged on the outside of the anti-rupture reinforcement layer, a high-temperature protective cover is arranged on the outside of the water-blocking layer, and a number of heat dissipation micropores are evenly opened on the outer wall of the anti-high-temperature protective cover.

[0006] Furthermore, the heat dissipation layer is filled with heat dissipation aluminum wire mesh.

[0007] Furthermore, the flame retardant layer is a polymerizable flame retardant resin layer, and six reinforcing ribs are evenly distributed inside the flame retardant layer, and the reinforcing ribs are made of metal steel material.

[0008] Furthermore, the interior of the anti-rupture reinforcement layer is cross-woven with metal steel wires.

[0009] Furthermore, the high temperature resistant protective sleeve is made of butyl rubber material.

[0010] Beneficial effects: 1. By setting up heat dissipation fillers and heat dissipation layers, the connecting wire can dissipate heat quickly and evenly in a high temperature environment. A number of heat dissipation micropores are evenly opened on the outer wall of the high temperature protective sleeve to achieve better heat dissipation effect and avoid expansion due to excessive temperature.

[0011] 2. The high temperature protection sleeve is made of butyl rubber, which has excellent heat resistance, aging resistance, chemical resistance and other functions. It can improve the high temperature resistance of the connecting line. The flame retardant layer and anti-rupture reinforcement layer can enhance the fire resistance and toughness of the connecting line to prevent rupture due to external force.

[0012] 3. When water vapor enters the connecting wire from the heat dissipation micropores, the water-blocking layer can effectively block and absorb the water vapor to prevent the connecting wire from getting damp. BRIEF DESCRIPTION OF THE DRAWINGS
