Description

Technical Field

[0001] The utility model relates to the technical field of household wiring harnesses, and more specifically to a high temperature resistant wiring harness component. Background Art

[0002] The main function of the home wiring harness is to connect various electrical appliances in the home to realize the transmission of electricity and power. It is like a "bridge" between electrical appliances, allowing them to operate normally. The home wiring harness can also protect the wires to prevent them from being damaged or short-circuited. Without the home wiring harness, our home electrical system will become chaotic and the electrical appliances will not work properly.

[0003] The existing high temperature resistant wire harness assembly has a relatively simple structure, which is easy to accumulate heat and cannot effectively dissipate heat, thus reducing the high temperature resistance of the wire harness assembly. In addition, due to the simple structure, the wire harness assembly is easily damaged when impacted, and cannot protect the internal wires, and has poor impact resistance. In view of this, we propose a high temperature resistant wire harness assembly. Utility Model Content

[0027] Furthermore, the heat dissipation group 2 includes a glass fiber sleeve 201 sleeved on the circumferential outer wall of the insulating sleeve 102. The glass fiber material has the effects of low density, light material, corrosion resistance, anti-aging and high temperature resistance.

The circumferential outer walls of the multiple butyl rubber tubes 202 are provided with heat-resistant rubber layers 203. The side wall adhesive of the heat-resistant rubber layer 203 is connected to the side wall of the polypropylene strip 204. When the household wire harness works for a long time, the heat generated by the core 101 is transferred to the glass fiber sleeve 201 through the insulating sleeve 102. The glass fiber sleeve 201 transfers the heat to the multiple butyl rubber tubes 202 and the multiple polypropylene strips 204. Part of the heat is absorbed by the butyl rubber tube 202, and the other part of the heat is transferred to the external space through the polypropylene strip 204. Through the mutual cooperation of the multi-layer structure, heat absorption and heat dissipation are performed, so that the high temperature resistance effect of the wiring harness assembly is good;

[0029] It is worth noting that, in order to make the protection object of the wiring harness assembly clear, the insulating sleeve 102 and the wire core 101 are existing household electrical wire products.

[0030] In addition, in order to make the glass fiber sleeve 201 have better heat resistance and anti-aging effects, the glass fiber sleeve 201 is formed by pressing a glass fiber material mixed with an adhesive, and has a thickness of 1.5 mm.

[0031] Finally, in order to make the polypropylene strip 204 have better heat absorption and heat dissipation effects, the polypropylene strip 204 is made of thermoplastic plastic material, which is made of propylene through polymerization reaction. The cross-section of the polypropylene strip 204 is a combination of semicircular and trapezoidal shapes.

[0032] Working principle: When the device is needed to work, the heat generated by the wire core 101 is transferred to the glass fiber sleeve 201 through the insulating sleeve 102. The glass fiber sleeve 201 transfers the heat to multiple butyl rubber tubes 202 and multiple polypropylene strips 204. Part of the heat is absorbed by the butyl rubber tubes 202, and the other part of the heat is transferred to the external space through the polypropylene strips 204.
