What is a terminal connector? What is its function?

A terminal connector, also known as a terminal block, is a type of electrical connector used to connect wires or cables to electrical or electronic equipment to transmit current or signals. It consists of a series of metal contacts that accept a set of wires or cables. Terminal connectors can be categorized into different types, including screw terminals, spring terminals, and crimp terminals. Screw terminals are a common type of terminal connector that makes an electrical connection through a spiral-shaped contact. Wires or cables are inserted into the terminal connector through the interface and the spiral contact is screwed to clamp the wires or cables. Spiral terminals are typically used in low power circuits for applications where the wire or cable is inserted and removed less frequently. Spring terminals use a spring-loaded contact mechanism to make an electrical connection by compressing the wire or cable. When a wire or cable is inserted into a spring terminal, the spring contact mechanism automatically opens and clamps the wire or cable after insertion. Spring terminals are typically used in high power circuits for applications where wires or cables need to be inserted and removed frequently. Crimp terminals use a pressure contact mechanism to make an electrical connection by pressing the wire or cable into a through-hole in the terminal connector. Crimp terminals are typically used in high power circuits for applications that require high reliability and long life. Terminal connectors offer many advantages, such as ease of installation, ease of maintenance, and space savings. They are also reusable, allowing terminal connectors to be used for multiple connections and disconnections. Terminal connectors can be widely used in industrial control systems, electric power systems, automotive electronics, avionics, medical equipment, communication equipment and other fields. In short, terminal connector is a simple, reliable and easy-to-use electrical connector that can provide a stable and safe electrical connection. It is widely used in various electronic devices and electrical equipment.
