What is a Terminal Block Plug?

What is a terminal block plug? Terminal plugs are accessories for electrical connection.
Terminal block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors.
Introduction to terminal plug:
Terminal block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. In addition to PCB board terminals, the most widely used ones are hardware terminals, nut terminals, spring terminals and so on.

Definition of terminal plug
Terminal blocks are used to facilitate the connection of wires. It’s actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert wires, and there are screws for tightening or loosening. For example, two wires need to be connected sometimes and disconnected sometimes. At this time, they can be connected with terminals, and can be disconnected at any time without having to weld them or twist them together, which is very convenient and quick, and is suitable for a large number of wire interconnections. In the power industry, there are special terminal blocks and terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, common, breakable, etc. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass.

Classification of terminal plugs
Terminal blocks can be divided into: European terminal block series;
Plug-in terminal series; Transformer terminal;
Building wiring terminals; fence terminal series; spring terminal series;
Rail-type terminal series; through-wall terminal series; photoelectric coupling terminal series, etc.

Reference standards for terminal plugs
skills requirement:
There should be no obvious defects in appearance, such as weld lines, shrinkage cavities, inconsistent colors, etc.
Shake the product, the screws should not fall off.
The pin is integrated with the plastic part and cannot be pulled out easily.
The pins should be arranged neatly without skewing.
Can be smoothly inserted into the circuit board with the corresponding number of holes.
When mated with mating, the tightness is appropriate.
Continuity test should meet the requirements.
The number of effective holes in the open combination mold is 2-24P
