What are the main types of terminal blocks

The terminal is an accessory product used to realize electrical connection, which is part of the connector. In a narrow sense, a terminal refers to a piece of metal enclosed in insulating plastic, with holes at both ends for inserting wires. The broad term terminal refers to a connector, which is also called a terminal block.

There are many types of terminal blocks and rich models. Among them, the common types of terminals are as follows:

1. Pluggable terminal blocks

It consists 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 this connection bottom and this anti-vibration design ensure the long-term airtight connection of the product and the reliability of the finished product.

2. Barrier terminal block

It is able to realize safe, reliable and effective connection, especially in the use environment of high current and high voltage, which is widely used.

3. Spring type terminal

It 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 elevator control, instrumentation, power supply, chemistry and automobile power, etc.

4. Rail-type terminal blocks

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.

5. Wall-through terminal

Using screw connection technology, the insulation material is PA66 (flame retardant grade: UL94, V-0), and the connector is made of high-quality and highly conductive metal materials.
