Problems solved by technology

Therefore, the outer layer of aramid knitted mesh tube and the inner layer of glass fiber braided tube in the wire harness protective sleeve are fixed together after being soaked in polyurethane solution and silicone resin and then cured. The protective sleeve is impact resistant, and since the coating of the harness protective sleeve does not completely cover the mesh of the braided mesh, it is not waterproof

Description

technical field [0001] The invention belongs to auto parts, and in particular relates to a new energy automobile wiring harness protective cover and a preparation method thereof. Background technique [0002] The wire harness refers to the contact terminal (connector) punched from copper and the wire and cable after crimping, and then plastic insulator or metal shell on the outside, and then bundled with wire harness to form a connected circuit component. The new energy vehicle wiring harness is the main body of its circuit network. The wiring harness is directly exposed to moisture or high temperature environment, which will not only affect the transmission of the wiring harness signal, but even burn the wiring harness, causing safety accidents. Therefore, it is necessary to protect the automotive wiring harness. [0003] At present, the wiring harnesses of new energy vehicles are mostly protected by protective sleeves such as multi-hole bellows, braided tubes, and winding...
