[0002] Electronic wiring harness generally refers to a low-voltage electronic wire group, which builds a bridge of communication between two or more isolated circuits so that current can flow and realize the functions of various electronic components. It is an indispensable component in various electrical and electronic equipment. The composition of complex wiring harnesses also needs to be supplemented with: tape, cable ties, casing, sheath, labels, etc.

[0003] The Chinese utility model with patent announcement number CN216084374U discloses an electronic wiring harness protective cover, including an upper outer plate, one end of which is connected to an adjustment spring; a lower outer plate, which is fixedly connected to the lower end of the adjustment spring, and the upper outer plate and the lower outer plate are both semi-circular arc structures. Compared with the existing device, the electronic wiring harness protective cover can be used for electronic wiring harnesses of different sizes by adjusting the distance through the arc-shaped upper outer plate and the lower outer plate, and the adjustment spring has a certain elasticity and will not be over-extruded, resulting in electronic wiring harness crushing; the protective cover can be fixed in position by the set fastening ring, and the fastening ring is made of a material with elastic deformation ability, which can be deformed in conjunction with the upper outer plate and the lower outer plate, and is convenient to use. The inner diameter of the fastening ring can be adjusted by the set fastening bolt, so as to fix the wiring harness, and the fastening bolt can be directly passed through the connector when used. However, there are some problems in the use process: multiple wire harnesses gathered together for a long time working easily causes high temperature and greatly reduces the service life of the wire harnesses. Therefore, an electronic wire harness protective cover is proposed to solve the above problems. Utility Model Content
