New energy vehicle connector is one of the main categories of connectors.In recent years, with the development of new energy vehicles in China, it is gradually separated from the traditional high voltage and high current and the traditional low voltage automobile connector.

Compared with the traditional high-voltage and high-current connectors, the working conditions of the new energy vehicle connectors are more complex and changeable, and the reliability requirements of the connectors are higher.

Compared with traditional low-voltage automotive connectors, the increased voltage level (the current mainstream system voltage is higher than 300V DC) increases the risk of electric shock injury to human body and puts forward higher requirements for safety.

The safety of new energy vehicle connectors; As a result, the insulation and protection requirements of the product are improved compared to traditional low-voltage plug-ins.

The role of the NEV connector is mainly to ensure the high voltage interconnect system of the car, that is, to build a bridge where the internal circuit is blocked or isolated to allow the current to flow.

The composition of the connector for new energy vehicles can usually be divided into three parts: the auxiliary structure, such as the shell and seal part, the insulation part and the conductive contact pair.

The function of connection and conduction can be realized through the coordination and mutual cooperation between the plug sleeve and the socket sleeve.

High-voltage connectors are mainly used in high-voltage and high-current circuits of new energy vehicles, and act at the same time as conductive cables.

It transmits the energy from the battery pack to various parts of the vehicle system through different circuits, such as the battery pack, the motor controller, and the DCDC body power unit (such as the converter and charger).

The use environment of new energy vehicle connectors

Because metal materials have better mechanical strength than plastic. Therefore, in some harsh environments, metal connectors are more suitable.

For example, special vehicles, muck trucks and electrical connections are not protected when laying out the entire vehicle.

At this point, metal connectors are slightly superior to plastic connectors in terms of environmental impact and mechanical strength.

New energy vehicle connector shielding method

With regard to shielded connectors, since the housing of metal connectors is used for shielding, it forms a carrier for shielding protection.

In general, metal connectors provide better shielding than plastic connectors and are more compact in appearance.
