Description
Technical Field
[0001] This utility model relates to the field of electronic wire harness technology, and in particular to multi-level thermal insulation electronic wire harnesses. Background Technology
[0002] Electronic wire harnesses refer to a combination of wires and connectors used to connect and transmit electrical signals, power signals, and control signals. Existing electronic wire harnesses have poor thermal insulation performance. When used in low-temperature environments such as cold storage and refrigerated trucks, the outer wrapping layer of the electronic wire harness is prone to hardening and brittleness, which shortens the service life of the surface wrapping layer of the electronic wire harness, making it prone to cracking and damage, thus affecting its service life. Therefore, multi-level thermal insulation electronic wire harnesses are designed to solve the above problems. Utility Model Content
[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a multi-level thermal insulation electronic wire harness.

The left and right ends of the wire harness body are electrically connected to connectors. The wire harness body includes a core wire, a thermal insulation layer, an antifreeze layer, a heat insulation layer, and an insulating layer. The core wire is located on the innermost side of the wire harness body. The thermal insulation layer is wrapped around the core wire. An antifreeze layer is applied to the outer surface of the thermal insulation layer. A heat insulation layer is fixed to the outer surface of the antifreeze layer with adhesive. An insulating layer is fixed to the outer surface of the heat insulation layer with adhesive.

The wire harness positioning components include a fixing sleeve, a mounting plate and bolt holes. The mounting plate is fixedly provided at the bottom of the fixing sleeve, and bolt holes are provided at the four corners of the upper surface of the mounting plate.
[0010] Preferably, the diameter of the central through hole of the fixing sleeve is equal to the outer diameter of the wire harness body.
[0011] Preferably, there are three wire harness positioning components. The two wire harness positioning components near the connector are fixed on the wire harness body, and the wire harness positioning component in the center of the wire harness body slides on the wire harness body.
[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

It exhibits excellent heat resistance and oxidation resistance, and its electrical insulation properties are comparable to those of silicone rubber, ensuring insulation performance. However, due to its enhanced resistance to chemical corrosion, it may be more suitable for use in certain special environments. Furthermore, fluorosilicone rubber does not harden at low temperatures, ensuring the flexibility of the wire harness body 1 and guaranteeing its service life.

This double insulation ensures the normal use of the wire harness at low temperatures and guarantees the service life of the wire harness.
[0015] 3. This utility model incorporates wire harness positioning components. Three wire harness positioning components are connected to the wire harness body. When connecting two components, the two wire harness positioning components closest to the connector are bolted to the two electrical components respectively, ensuring the stability of the connector connecting the electronic components. This prevents the connector from detaching from the components when the wire harness body is pulled. Furthermore, by sliding the wire harness positioning component in the center of the wire harness body 1, the center of the wire harness body is fixed in a suitable position, increasing the stability of the connection between the two components and enhancing its practicality.
