Terminals can be divided into European terminal series, plug-in terminal series, barrier terminal series, spring terminal series, track terminal series, through-wall terminal series, photoelectric coupling terminal series, etc.

The plug-in series terminal block is made up of two parts plug-in connection, one part presses the wire tightly, and then plugs into the other part, this part is soldered to the PCB board. The mechanical principle of the connection bottom and the 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.

A variety of socket designs can be matched with different matrix insertion methods, such as horizontal, vertical or inclined to the printed circuit board, etc., and different methods can be selected according to customer requirements. Either metric wire gauge or standard wire gauge can be selected.  
Pluggable terminal blocks are the most cost-effective form of existing wiring technology. 

Barrier series terminal blocks are able to realize safe, reliable and effective connection, especially in high current and high voltage environment.  
Spring-type terminal is a new type of terminal that utilizes spring-loaded devices. It has been widely used in the world's electrical and electronic engineering industries: lighting, elevator elevator control, instrumentation, power supply, chemical and automotive power, etc.  

Rail-mounted terminal blocks adopt reliable screw connection technology, electronic tolerance technology and the latest electrical connection technology, and are widely used in power electronics, communications, electrical control and power supplies.  

Rail-type series terminal blocks adopt crimping and unique thread self-locking design, which makes the wiring connection reliable and safe. The appearance design of this series of terminal blocks is beautiful and generous, and it can be equipped with a variety of accessories, such as short-circuit strips, identification strips, baffles, etc.
