AUPINS electrical connectors are used to connect electrical signals between devices, components, equipment, and systems. They use electrical signals and mechanical forces to connect and disconnect circuits, transmit signals or electromagnetic energy, including electrical signals such as high-power electrical energy and data signals. They are widely used in communications, aerospace, computers, automobiles, industry, and other fields.

The functions of various types of connectors are different, which leads to differences in the design and manufacturing requirements of different types of connectors. Generally speaking, AUPINS electrical connectors need to meet the requirements of good contact and reliable operation. Among them, the transmission of high-power electrical energy also requires low contact resistance, high current carrying capacity, low temperature rise, and high electromagnetic compatibility; the transmission of high-speed data signals requires good circuit impedance continuity, small crosstalk, low delay, and high signal integrity.AUPINS electrical connector consists of a contact, an insulator, a shell, and accessories. The contact is the core component of the connector, and the electrical connection is achieved by the insertion of male and female contacts. The male contact is a rigid part, usually made of brass or phosphor bronze, while the female contact is a jack, which is elastically deformed by the elastic structure when the pin is inserted, and forms a close contact with the male contact. The insulator acts as an insulator between the contacts and between the contacts and the housing. The housing is the outer shell of the connector, providing protection and alignment during mating.
