What are connectors? What are the main materials that connectors are made of?

Connector is a commonly used component in electronic equipment, which can connect different parts or lines together so that they can properly transmit electrical signals and electrical energy. Connectors are widely used in various electronic devices, such as TVs, computers, cell phones, automobiles, medical devices, etc. They not only connect various devices inside the body, but also connect various sensors, displays, keyboards, etc. outside the body. Connectors are mainly composed of shells, connectors, terminals, seals and so on. Shell is the main part of the connector, it protects the internal components from damage, and play a role in the mechanical protection of the connector. Shell is usually made of metal or plastic materials. Metal shell connector has high strength and corrosion resistance, widely used in military, aerospace and other fields; while the plastic shell connector has a lighter weight and good insulation properties, widely used in consumer electronics, medical equipment and other fields. The connector is an important part of the connector, which determines how the connector is inserted and removed and the shape of the plug. The connector is usually made of metal material with high strength and conductivity. There are many types of connectors, the common ones are circular connectors, rectangular connectors, bayonet connectors, board-to-board connectors and so on. Each type of connector has a different shape and number of plugs, so you need to choose the appropriate connector for your specific connection needs. Terminals are another important component of connectors, which are used to connect wires in a circuit. Terminals are usually made of copper or copper alloys and have good electrical conductivity and corrosion resistance. Terminals are also available in a variety of shapes, commonly pin-type terminals, screw-type terminals, crimp-type terminals and so on. The selection of terminals should be based on the type of connector and the use of the environment to choose the appropriate type and material. Seal is an important part of the connector, it is used to protect the connector from water, dust, oil and other external environment. Seals are usually made of silicone, rubber and other materials with good sealing and high temperature resistance. There are also various types of seals, such as O-rings, U-rings, bidirectional seals and so on.
