What exactly are terminal blocks?

The electrical connection is the function of the terminal block. It can also be said that the terminal block is actually a kind of connector, which is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires, and there are screws for tightening. Fixed or loose, such as two wires, sometimes need to be connected, sometimes need to be disconnected, then you can use the terminal to connect them, and can be disconnected at any time, without having to weld or twist them together, very convenient fast.

The terminal block is an accessory product used to realize electrical connection, and it is classified as a connector in the industry. With the increasing degree of industrial automation and the increasingly strict and precise requirements of industrial control, the demand for terminal blocks is gradually increasing. The rapid development of the electronics industry has made the use of terminal blocks more and more extensive and more and more types. The terminal blocks can be divided into WUK terminal blocks, European terminal block series, plug-in terminal block series, transformer terminal blocks, building wiring terminals, fence type terminal blocks series, spring type terminal block series, track type terminal block series, through-wall Type terminal series, photocoupler terminal series, 110 terminal, 205 terminal, 250 terminal, 187 terminal, OD2.2 ring terminal, 2.5 ring terminal, 3.2 ring terminal, 4.2 ring terminal, 2 ring terminal , 6.4 ring terminals, 8.4 ring terminals, 11 ring terminals, 13 ring terminal flag series terminals and sheath series, various ring terminals, tubular terminals, terminal blocks, copper strip iron strip (2-03, 4-03, 4-04, 6-03, 6-04) etc. At present, the most widely used are PCB board terminals, hardware terminals, nut terminals, and spring terminals.

The plastic insulating material and conductive parts of the terminal are directly related to the quality of the terminal, and they determine the insulation performance and conductivity of the terminal respectively. Failure of any terminal will lead to failure of the entire system engineering.
As an accessory product for precision operation, the quality of motion control terminals is always concerned by customers, and how to effectively check and prevent them has become a topic of concern.
