Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage ignition cables, and particularly relates to a high-voltage ignition cable. Background Art

[0002] When a new energy vehicle starts and is powered on, the voltage is relatively high, and a high-voltage ignition cable is required. Ordinary high-voltage ignition cables cannot be disassembled. If there is a problem inside, the whole cable can only be replaced, which is very wasteful and the replacement is relatively slow. Moreover, as the requirements for vehicle performance are getting higher and higher, the voltage of the vehicle is also getting larger. The large voltage brings heat stress to the cable, and it is easy to generate heat during use.

[0003] For example, a high-voltage ignition cable for a new energy vehicle with quick connection provided in the Chinese patent application with the application number 202221191301.3 includes a conductor and a cooling layer. The conductor is inserted into the inside of the cooling layer. An insulating layer is wrapped around the outside of the conductor. A talcum powder layer is provided on the outer wall of the insulating layer. And the conductor is inserted into the inner wall of the cooling layer through the talcum powder layer. And the cooling layer includes a fireproof layer. And a first reinforcing rib is provided inside the fireproof layer. And the outer wall of the fireproof layer is connected to an outer layer through a supporting surface. And a cooling water cavity is formed between the outer layer and the fireproof layer. And water inlets and outlets are provided at both ends of the outer layer. The cable conducts electricity through the conductor. And when it is damaged, the conductor can be directly pulled out. When replacing the cable, it is not necessary to replace the whole cable, and only the conductor needs to be replaced, reducing material waste. And by passing water through the cooling layer, the problem of conductor heating can be effectively solved.

[0004] However, the following problems still exist in this technical solution: In this technical solution, the conductor is immersed in cooling water. Over time, the cooling water is likely to corrode the outer surface of the conductor, resulting in damage to the conductor. Summary of the Utility Model
