Various classifications and application scenarios of PCB wiring terminals

Terminal blocks are one of the branches of the entire connector, but their main characteristics are the same, mainly through connection to achieve their main performance. They play a significant role in different fields. For example, in the power industry, terminal blocks are mainly a plug and play type connection device, mainly used for control and connection, and are also very convenient to use. In the development of the world, China's development is rapid.

Terminal block: It is a basic accessory used to achieve electrical connections, and is the fixed part that connects the endpoints or contacts between wires, appliances, and control boards.

PCB wiring terminal: Generally speaking, it is a type of accessory product for PCB circuit boards to achieve electrical connections, and is classified as a connector in industry.

In addition, there are some nicknames for PCB wiring terminals: they are also known as wiring strips, terminals, terminal blocks, terminal blocks, and so on, because their appearance is generally in a row shape.

The function of PCB wiring terminals is to ensure the electrical connection is firm, safe, beautiful, and to improve the convenience and speed of electrical installation and maintenance.

Terminal blocks are widely used on PCB circuit boards in industry, with the following specific types:

1. PCB plug-in terminal blocks

It is composed of two parts that are plugged and connected, with one part compressing the wire and then inserting it into the other part. This part is welded to the PCB board and is suitable for automated electrical connection systems.

2. PCB direct soldering terminal blocks

Using the lifting principle of the wire clamp body, the welding foot and the wire clamp body are divided into two parts. The shell is sturdy and reliable, with precise needle spacing, suitable for the power supply industry, controller field, access control systems, and so on.

3. PCB fence type terminal blocks

It is able to achieve safe, reliable, and effective connections, especially in environments with high currents and voltages, which are widely used.

4. PCB spring type terminal blocks

It is a new type of wiring terminal that utilizes spring type devices and has been widely used in lighting, elevator lifting control, instruments, power supply, chemistry, and automotive power.
