Heat shrinkable tube is also a commonly used protective material. It is a special heat shrinkable sleeve made of polyolefin. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer of hot melt adhesive. The material has the characteristics of insulation, corrosion resistance, wear resistance, etc. The inner layer has the advantages of low melting point, waterproof sealing and high adhesion. At present, the double-arm heat shrinkable tube is widely used, which is mainly used in the connection point of the wire harness, focusing on Sealed and waterproof. At the same time, tape is the most basic and widely used wire harness protective material, which has the characteristics of temperature resistance, wear resistance, oil resistance, insulation, etc.
When the engine wiring harness is assembled, the bellows are connected by snaps, and the fixing of the wiring harness branch is completed by the wire tie. The function of the wire tie is to fasten the wire harness and make it firmly and reliably fixed on the cylinder block or bracket to prevent the wire harness from vibrating. , displacement or interference and damage the wiring harness.
