Description

Technical Field

[0001] The utility model belongs to the technical field of cross-linked automotive wire materials, and particularly relates to a high-temperature resistant cross-linked automotive wire material structure of high polymers. Background Art

[0002] Cross-linked automotive wire materials mainly refer to wire insulation materials processed by cross-linking technology. Cross-linking technology is an important means to improve the heat resistance of materials. It can transform thermoplastic materials from a linear polymer structure into a three-dimensional network polymer, thereby improving the mechanical properties, heat resistance, and liquid resistance of materials. Through cross-linking treatment, the heat resistance of these materials is significantly improved, thus meeting the requirements of the automotive electrical system for the heat resistance of wires.

[0003] The existing cross-linked automotive wire material structures have the following problems in application:

[0004] 1. In the actual use process of traditional cross-linked automotive wire material structures, a heat insulation material structure is usually covered on one side of the wire. However, since the vehicle is long-term exposed outdoors, the wires inside the cross-linked automotive wire will be affected by the external environment. Therefore, the high-temperature resistance effect is poor during use.

[0005] 2. When most cross-linked automotive wire material structures are applied, the cables inside the cross-linked automotive wire are often complex and intertwined. Therefore, fixing parts are used to fix the positions of the cables. Once the fixed cables are extruded by external forces, the wire cores are easily damaged during application. Summary of the Utility Model

[0014] 1.

[0028] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail the structure of a high-molecular heat-resistant cross-linked automotive wire material of the present utility model with reference to the accompanying drawings.

[0029] As Figures 1-5 shown, a structure of a high-molecular heat-resistant cross-linked automotive wire material of the present utility model includes a wire core 1. A first heat insulation sleeve 2 and a second heat insulation sleeve 3 are provided outside the wire core 1. The first heat insulation sleeve 2 and the second heat insulation sleeve 3 are symmetrically distributed. A bonding surface 12 is provided on the side surfaces of the first heat insulation sleeve 2 and the second heat insulation sleeve 3. Due to the installation of the bonding surface 12, the first heat insulation sleeve 2 and the second heat insulation sleeve 3 can be spliced and fixed. Heat insulation blocks 4 are provided outside the first heat insulation sleeve 2 and the second heat insulation sleeve 3. By installing the first heat insulation sleeve 2, the second heat insulation sleeve 3, and the heat insulation blocks 4 outside the wire core 1, internal heat insulation and external heat insulation can be achieved, and a double heat insulation effect can be realized during use, with stronger heat insulation performance.

[0030] A second voltage-resistant block 8 is provided outside the first heat insulation sleeve 2, and a first voltage-resistant block 7 is provided outside the second heat insulation sleeve 3. The first voltage-resistant block 7 and the second voltage-resistant block 8 are symmetrically distributed. By installing the first voltage-resistant block 7 and the second voltage-resistant block 8 outside the wire core 1, the wire core 1 can be prevented from being damaged during application.

[0031] A plug board 9 is provided on the side surface of the first voltage-resistant block 7, and a slot 10 is opened on the side surface of the second voltage-resistant block 8. The plug board 9 is embedded inside the slot 10. Due to the provision of the plug board and the slot 10, it is convenient to splice and fix the first voltage-resistant block 7 and the second voltage-resistant block 8.

[0032] An insulating layer 13 is provided outside the first voltage-resistant block 7 and the second voltage-resistant block 8, and heat insulation blocks 4 are provided outside the insulating layer 13. The heat insulation blocks 4 are annularly distributed. Due to the provision of the insulating layer 13, current can be effectively isolated, the risk of electric shock can be reduced, and thus people's safety can be protected.

[0033] A wrapping layer 5 is provided outside the heat insulation blocks 4, and a shielding layer 6 is provided outside the wrapping layer 5. Due to the provision of the shielding layer 6, the electromagnetic field inside the cable can be effectively isolated from the external electromagnetic field, preventing interference of the external electromagnetic field with the signals inside the cable.

[0034] An outer protective sleeve 11 is provided outside the shielding layer 6. There are three sets of wire cores 1. Since the outer protective sleeve 11 is provided and has the functions of moisture-proof and waterproof, it can effectively prevent moisture and humidity from entering the cable interior.

[0035] The working principle of the high-molecular heat-resistant cross-linked automotive wire material structure: When using this material, first, in order to prevent the wire and cable from being damaged when pulled or extruded externally, a structure for preventing extrusion is installed outside the wire core 1. By installing a first pressure-resistant block 7, a second pressure-resistant block 8, an insertion plate 9, and a slot 10 outside the wire core 1, before packaging the wire core 1, the first pressure-resistant block 7 and the second pressure-resistant block 8 are directly attached to the outside of the wire core 1. An insertion plate 9 is provided outside the first pressure-resistant block 7, and a slot 10 is opened on the side of the second pressure-resistant block 8. Then the insertion plate 9 is directly inserted into the slot 10, so that the first pressure-resistant block 7 and the second pressure-resistant block 8 can be spliced. Therefore, when applied, the wire core 1 can be prevented from being damaged, and the protection effect is stronger when being extruded externally. Secondly, in order to better insulate the wire material for automotive cross-linking, a double heat-insulating structure is installed. By installing a first heat-insulating sleeve 2, a second heat-insulating sleeve 3, an adhesive surface 12, and a heat-insulating block 4 outside the wire core 1, the first heat-insulating sleeve 2 and the second heat-insulating sleeve 3 are first sleeved outside the wire and cable. Since there is an adhesive surface 12 on the side of the first heat-insulating sleeve 2 and the second heat-insulating sleeve, the heat-insulating sleeve can be installed outside the wire core 1. Then an insulating layer 13 is provided outside the pressure-resistant block structure. Secondly, a heat-insulating block 4 is also installed outside the insulating layer 13, so that internal temperature insulation and external temperature insulation can be achieved, and the effect of double temperature insulation can be realized during use, and the heat-insulating performance is stronger. Finally, a wrapping layer 5 is installed outside the heat-insulating block 4. A shielding layer 6 is also installed outside the wrapping layer 5, and an outer protective sleeve 11 is also installed outside the shielding layer 6, so as to better protect the wire and cable.
