What are power cord terminals? What are the main types of terminals?

A power cord terminal is a type of power cord connector that is used to connect a power cord to a device or power outlet for the transmission of electrical energy. It is usually made of metal or electrically conductive material and has the function of fixing and conducting electricity. There are many types of power cord terminals, the following will introduce several of the common types of terminals. Plug Type Terminal: The plug type terminal is one of the most common power cord terminals used to connect devices and power outlets. It usually consists of two or more metal pins that match the jacks on an electrical outlet. Plug type terminals are characterized by easy unplugging and are commonly used in household appliances, computers and their peripherals. Socket type terminal: Socket type terminal is the matching connector of plug type terminal, used to receive plug type terminal. It is usually installed in the power outlet, with a matching plug jack, used to insert the plug and establish an electrical connection with it. The shape and specifications of the socket type terminals vary from place to place, such as the international common European standard, American standard and British standard sockets. Screw terminals: Screw terminals use threads to hold the power cord and clamp the wire to the terminal by turning a screw. It is usually made of metal material, has a reliable connection performance, commonly used in industrial equipment, electronic instruments and other occasions that require a solid connection. Spring Type Terminals: Spring type terminals utilize the elasticity of the spring to clamp the wires to the terminal without the need for screws. It has convenient connection and disassembly characteristics, widely used in audio equipment, automotive electronics, communications equipment and other fields. Quick-Plug Terminal: Quick-Plug Terminal adopts a specially designed connection method, which can quickly plug and unplug the power cord without additional tools. It usually consists of a plastic shell and metal contacts, and is widely used in electronic products, lighting equipment, power tools and so on. Leaded Terminals: Leaded terminals are usually composed of a piece of copper wire or conductor, and are used to connect the power input or output of equipment. It is often used in welding, brazing and other processes, through the welding or insertion of other connectors to achieve the transmission of electrical energy. pcb terminals: pcb terminals are specially used for printed circuit board (pcb) on the connector. It is usually fixed by soldering or inserting into holes on the PCB, and is used to connect the circuit board to other devices or components. In addition to the common power cord terminals mentioned above, there are many other types of terminals, such as fixed terminals, crimp terminals, snap terminals, etc., which play an important role in different industries and applications. The design and selection of these terminals need to take into account current capacity, contact reliability, protection and other requirements to ensure the safety and reliability of power transmission.
