Are there any requirements for the use environment of the terminal block?


A terminal is a type of connector created to facilitate wire connection. It is usually composed of insulating parts, conductive parts, solder legs and other parts, and there are shrapnel for spring-type terminals.

The termination is a process design and it is recommended to consider termination in the following cases: 

1. Due to factors such as debugging and maintenance, the wire at this position needs to be dismantled frequently. For example, two wires sometimes need to be connected and sometimes they need to be disconnected. At this point, they can be connected by terminals or disconnected at any time without soldering or twisting together, which is very convenient and fast. 

2. An enterprise electrical box or circuit board, etc., as a country as a whole, needs to be electrically connected with other external control circuit systems. Using the PCB terminal block on the circuit board makes it easier to detect the wire when there are some faults in the circuit, and it will not be time-consuming and laborious to remove the wire from the circuit board. 

3. Points of the same equipotentiality need to be connected to a large number of wires. There are holes at both ends of the terminal to be inserted into the wire, there are screws to fasten or loosen, and it is suitable for a large number of wire interconnections. In the power industry, there are special terminal blocks, junction boxes, covered terminals, single-layer, double-layer, current, voltage, Ordinary, damaged, etc. 

4. Due to the large diameter of the wire, it is inconvenient to connect with the screw terminal. The plug-in terminal is connected with the crimping frame, and the crimping frame can be connected with the large wire diameter to protect the wire from damage. 

5. When the current is large, it is necessary to increase the electrical connection of the contact area. Tb series high-current terminal blocks can meet the requirements of high-current wiring. 

6. Multiple wires need to be connected to the same terminal. Because the same terminal has multiple jacks, it is convenient for wires to be connected.

It has been nearly a hundred years since the invention and development of the terminal block in China. From the earliest combined terminal to the present various plug-in, direct welding, barrier, spring-type and even bare terminals, we have formed in the field of connectors. A complete electrical system interface information technology management system has been established. The scope of its use ability has also been expanded to many different fields such as rail urban transportation, security lighting, elevator power enterprise control, medical service equipment, etc., and various learning situations. In view of the convenient installation of terminal blocks and stable electrical equipment performance, it is gradually gaining the trust of students who know more about customers.
