Nowadays, electric vehicles are very common in society. Especially in recent years, new energy electric vehicles have made a breakthrough in sales and even have the opportunity to surpass traditional fuel vehicles. Compared with fuel vehicles, electric vehicles are special, with the characteristics of high voltage and high current. They are usually equipped with power supply systems with more than 300V and current of more than 200A. This is completely different from the traditional car only equipped with 12 / 24V power supply system. The safety measures of high-voltage distribution box, high-voltage line and connector of electric vehicle have become the safety aspects that need to be paid attention to.

High voltage line of electric vehicle refers to the component of connecting circuit formed by punching copper contact terminal (so-called connector) and wire (cable) after crimping, wrapped with plastic compression insulator or external metal shell, etc. In terms of function, there are two kinds of power lines carrying the power of driving actuator (actuator) and signal lines transmitting sensor input commands. Power lines are divided into low-voltage harness and high-voltage harness.
