power battery connector Performance and contact resistance test .The power battery connector is also known as the power battery connector, plug and socket, generally refers to the device connecting two active devices to transmit current. The function of the power battery connector is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. The form and structure of the power battery connector are ever-changing. With the different application objects, power, application environment and so on, there are different types of connectors.
The safe and reliable operation of the power battery connector is the core device to ensure the normal operation of the power system of the electric vehicle. The power battery connector is an indispensable part of the power system of the electric vehicle. The safety, reliability and environmental protection of the power battery connector are the key points of the design of the power battery connector.
The basic structural parts of the connector of the power battery include the contact, insulator, shell (depending on the variety) and accessories, and the contact is the core part of the connector to complete the electrical connection function. Generally, the contact pair is composed of positive contact and negative contact, and the electric connection is completed by inserting the negative and positive contact.
