The classification of wiring terminals can be distinguished in several ways, and there are three more common methods at present. According to the raw materials of the terminals, such as copper terminals, and according to the functions of the terminals, such as printed circuit board terminals, the last one is the classification that is more familiar to the market and divided according to the connection form of the terminal. There are mainly the following categories.
1. Pluggable terminal block
is made up of two parts plug-in connection, one part presses the wire tightly, and then plugged into the other part, this part is soldered to the PCB board. The mechanical principle of this connection bottom and this anti-vibration design ensure the long-term airtight connection of the product and the reliability of the finished product. Mounting ears can be added at both ends of the socket. The mounting ears can protect the tabs to a large extent and prevent the tabs from being arranged poorly. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body. The socket can also have assembly buckle and lock buckle. The assembly buckle can be more firmly fixed to the PCB board, and the locking buckle can lock the mother body and the socket after the installation is completed.
Various socket designs can be matched with different mother body insertion methods, such as horizontal, vertical or inclined to the printed circuit board, etc., and different methods can be selected according to customer requirements. You can choose either metric wire gauge or standard wire gauge, which is currently the most popular terminal type on the market.
2. Spring type terminal block
is a new type of terminal using spring-loaded devices, which has been widely used in the world's electrical and electronic engineering industries: lighting, elevator lifting control, instrumentation, power supply, chemistry and automobile power, etc.
3. Rail type terminal block
The use of crimping and unique thread self-locking design makes the wiring connection reliable and safe. The appearance design of this series of terminal blocks is beautiful and generous, and can be equipped with a variety of accessories, such as short-circuit strips, identification strips, baffles, etc.
4. Barrier terminal block
is able to achieve safe, reliable and effective connection, especially in the use of high current, high voltage environment is more widely used.
