2. Use and fixation of automobile nylon cable ties. These wire harnesses are fixed on the automobile sheet metal by automobile wire ties. The safety and reliability of the wire harness fixing is very important to the electrical safety of the whole vehicle. With the increase of vehicle engine functions, the wiring in the car cab and the engine need to communicate in real time, and more and more wiring harnesses need to be connected to the engine. The engine is a vibrating part and the vehicle body also vibrates, so the wiring harness arranged on the car will also vibrate. Therefore, the fixing stability of the wire harness depends not only on the ability of the wire tie to fix the wire harness, but also on the stability of the wire tie on the vehicle body. However, the connection structure of the traditional automobile wire harness tie and the body is too simple, and the tie is easy to loosen relative to the body, which causes the wiring harness and the tie to shake as a whole, which seriously affects the stability of the harness fixation. In view of the above-mentioned shortcomings, a new type of automobile wire tie has been developed, which not only improves the stability of the wire harness tie on the car body, there is no looseness between the wire harness tie and the car body, and reduces the shaking of the wire tie relative to the car body. , To ensure the stability of the wiring harness, and improve the flexibility of the connection.
