A battery connector is something that allows current to pass through this part to a given part, it can only carry current (AC and DC), not information flow. 

Depending on the type and model of the connector, the function is different.

The power battery connector is also known as the power connector, the power battery plug and the power battery socket. It generally refers to a device that connects two active devices to transmit current. The function of the power battery connector is very simple: when it is blocked in the circuit or Between the isolated circuits, a bridge of communication is set up, so that the current can flow and the circuit can achieve the predetermined function. The form and structure of the power battery connector are ever-changing, with the application object, power, application environment, etc. Connectors Different forms of connectors.

The safe and reliable operation of the battery connector is the core component to ensure the normal operation of the electric vehicle power system. The safety, reliability and environmental protection of the power battery connector are the main points of the power battery connector design.

1. Components of the battery connector

The basic components of a battery connector are:

①Contact ②Insulator ③Shell ④Accessory

1.1. Contacts

The important component of the battery connector is the contact piece, which generally consists of a male contact piece and a female contact piece to form a contact pair, and the electrical connection is completed by the insertion of the female contact piece and the male contact piece. Contacts are usually cylindrical, square column shape and flat shape, the material is brass, phosphor bronze. When performing the insertion operation, the elastic, deformable part is the female contact part.

The male contact part is a rigid structure and has a cylindrical, square or flat shape. The metal materials of the positive contacts are brass and phosphor bronze.

The female contact is an important part of the contact pair. When it is inserted into the male contact, it relies on the elastic force generated by the elastic structure to form a close contact with the male contact to complete the electrical connection. The structure of the female contact is matched with the structure of the male contact, there are cylindrical (split, necked), tuning fork, cantilever beam (longitudinal slot), folded (longitudinal slot, 9-shaped) ), box-shaped (square jack) and hyperboloid spring jacks, etc.

The reliability of the contact of the power battery connector is related to the contact resistance between the contact pairs of the connector. Generally, the smaller the resistance of the electronic connector, the better, which can reduce the power loss caused by the contact resistance, and also reduce the heating of the contact point and the contact Too much heat will increase the contact resistance value. In addition, if the heat dissipation is not good, the excessive heat will soften the metal, accelerate the oxidation and wear of the metal surface, and reduce the quality of the connector. If it is serious, If it is serious, it will cause the connection Plastic shell softening deformation, aging and so on.

1.2. Insulators

Insulators are also commonly referred to as substrates or plugs. The purpose is to arrange the contacts according to the required position and space, so that the metal contacts maintain a certain spatial distance, so as to ensure the insulation performance between the contacts and the housing. The material of the insulator is very strict, and good insulation resistance, withstand voltage performance and ease of processing are the basic requirements for selecting materials to be processed into insulators.

1.3. Shell

The shell, which is the outer cover of the connector, is mainly used to provide mechanical protection for the built-in insulating mounting plate and latch, and to provide position calibration for the connector to be fixed to the device when the insertion action is performed. The shell can also effectively prevent the erosion of moisture and corrosive liquids, and prevent the entry of dust.

1.4. Accessories

Accessories are divided into structural accessories and installation accessories. Structural accessories such as clamping rings, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Structural accessories play the role of positioning and sealing. Installation accessories such as screws, nuts, bolts, spring rings and other accessories, most of which have standard parts and common parts. The installation accessories are mainly used to install the connector on a certain platform and play a fastening role.
