Different Types of Terminal Block Connectors
A terminal is an interface used in electricity. It can be said that through the use of terminal blocks, we are able to make better use of our electrical. Although the terminal block seems to be very simple in this way, in fact, if we want to use the terminal block well, we need to understand the classification of the terminal block, so that we can use the terminal block better and correctly. Then, let's introduce the classification of terminal blocks to you, so that everyone can use the terminal blocks connectors better.
Terminals can be divided into:
- Plug-in terminal block
- Barrier terminal block
- Spring terminal block
- Din rail terminal block
- Through-wall terminal block
Plug-in terminal block
It consists of two parts plug-in connection, one part presses the wire, and then plugs into the other part, which is soldered to the PCB board. The mechanical principle of the bottom connection 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 poorly arranged. At the same time, this socket design can ensure that the socket can be inserted into the mother correctly. Receptacles can also have assembly snaps and locking snaps. The assembly buckle can be used to more firmly fix 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 mother insertion methods, such as: horizontal, vertical or inclined to the printed circuit board, etc., and different methods can be selected according to customer requirements. Available in both metric and standard wire gauges, it is the best-selling terminal type on the market today.
Barrier terminal block
It can realize safe, reliable and effective connection, especially in the environment of high current and high voltage.
Spring terminal block
Spring terminal is a new type of terminal using spring device, which has been widely used in the world's electrical and electronic engineering industries: lighting, elevator control, instrumentation, power, chemistry and automotive power.
Din rail terminal block
The use of crimping wire and unique thread self-locking design makes the wiring connection reliable and safe. The design of this series of terminal blocks is beautiful and elegant, and can be equipped with a variety of accessories, such as short-circuit strips, identification strips, baffles, etc.
H-type through-wall terminal block
Using screw connection wire technology, the insulating material is PA66 (flame retardant grade: UL94, V-0), and the connector is made of high-quality high-conductive metal material. H-type through-wall terminal blocks can be installed side by side on panels with a thickness of 1mm to 10mm, and can automatically compensate for the distance between the panel thickness adjustment to form a terminal block with any number of poles, and isolation plates can be used to increase air gaps and creepage distance. The through-wall terminal block can be firmly installed in the rectangular reserved hole on the panel without any tools, and the installation is extremely convenient. equipment, electrical control cabinets, etc. With good insulation performance and high protection level, users only need to directly connect the external wiring to work, eliminating many unnecessary wiring steps.
In above we have introduced the different classifications of terminal blocks. I believe that you can understand from the above that different terminals are not only different in shape, but also have different advantages in use. Therefore, it is recommended that you understand the classification of different terminals, so that we can use the terminals better according to our own situation. Correct use of terminal blocks can also prevent the safety of our electrical use.
