What is the structure and function of the contacts of an automotive connector?

I. How is the structure and role of automotive connector contacts? Contacts as a new energy vehicle electrical connectors by one of the four basic structural components, its main role is to be blocked in the circuit 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. Contacts, is the new energy electric vehicle connectors to complete the electrical connection function of the core parts. Generally by the positive and negative contacts composed of contact pairs, through the negative and positive contacts of the insertion and completion of the electrical connection. Positive contact is a rigid part, its shape is cylindrical (round pin), square cylindrical (square pin) or flat (insert). Positive contacts are generally made of brass, phosphor bronze. Negative contact parts that jack is the key parts of the contact pair, it relies on the elastic structure of the new energy electric vehicle connector with the elastic deformation occurs when the connector insertion and closure of the elastic force and the positive contact parts to form a close contact, complete the connection. New energy vehicle electrical connector jack structure of many kinds, there are cylinder type (split slot, indentation), tuning fork type, cantilever beam type (longitudinal slotted), folded type (longitudinal slotted, 9-shaped), box (square jack) and hyperbolic wire spring jacks and so on.
