Various classifications and application scenarios of PCB terminals

Wiring terminal is one of the branches of the whole connector, but its main characteristics are the same. It mainly gives play to its main performance through connection, and plays a relatively large role in different fields. For example, in the power industry, wiring terminal is mainly a plug-in connection equipment, which is mainly used for control and connection. It is also very convenient to use. In the development of the world, China's development is rapid.



Wiring terminal: it is a basic accessory used to realize electrical connection. It is a fixed part connecting the end points or contacts between wires, appliances and control boards, which is called wiring terminal.



PCB wiring terminal: Generally speaking, it is an accessory product for PCB circuit board to realize electrical connection. It is divided into the category of connector in industry.



In addition, PCB terminals also have some aliases: because their shape is generally in the shape of continuous row, they are also known as wiring row, terminal post, terminal row, terminal block, terminal block and so on.



The function of PCB terminal block is to ensure that the electrical connection is firm, safe and beautiful, and improve the convenience and rapidity of electrical installation and maintenance.



In industry, wiring terminals are widely used on PCB circuit boards. The specific types are as follows:



1. PCB plug-in terminal block



It is formed by inserting and connecting two parts. One part compresses the wire and then inserts it into the other part. This part is welded to PCB board and is suitable for automatic electrical connection system.



2. PCB direct welding terminal



Using the lifting principle of wire clamp body, the welding foot and wire clamp body are divided into two parts. The shell is firm and the needle distance is accurate. It is suitable for power supply industry, controller field, access control system, etc.



3. PCB fence type terminal block



It can realize safe, reliable and effective connection, especially in the environment of high current and high voltage.



4. PCB spring type terminal block



It is a new type of wiring terminal using spring device. It has been widely used in lighting, elevator lifting control, instruments and meters, power supply, chemistry and automobile power.
