What is the difference between a connector and a terminal block?

Connectors and terminals are relatively common electronic components. They have similarities and many differences. In order to help

you understand in depth, this article will summarize the relevant knowledge of connectors and terminal blocks. If you are interested in

what this article is about to cover, then continue reading.

by definition

Connectors generally refer to electrical connectors, which are the general term for all connectors, and transmit current or signals through

the docking of yin and yang poles; terminals are also called terminal blocks.

The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic, with holes at

both ends for inserting wires.


From the scope of belonging

Terminals are part of the connector.

Connector is a general term. Generally, the common connectors we see usually include two parts: plastic shell and terminal.The shell

is plastic and the terminals are metal.


From practical application

Terminal block is a kind of connector, generally belongs to rectangular connector.

In the electrical or electrical field: Connectors and connectors are the same type of product. It is generally understood as an electronic

component that can be quickly connected by inserting or twisting one end of the male connector into one end of the female connector

without using tools. A terminal is generally understood as an electronic product that requires the use of certain tools, such as screwdrivers

and cold press pliers, to connect two connection points together. They are commonly used for power input and output.

There are many specific classifications of connectors, such as rectangular connectors, circular connectors, stepped connectors, etc.

Terminal block is a kind of connector, generally a rectangular connector, and the scope of use of the terminal block is relatively simple.

It is generally used in the field of electronics and electrical, and is used for internal and external connections of PCB circuit boards, printed

boards, and power distribution cabinets.

Terminal blocks are used more and more, and there are more and more types. At present, in addition to PCB board terminals, hardware

terminals, nut terminals, spring terminals, etc. are widely used. In the power industry, there are special terminal blocks and terminal boxes,

all of which are terminal blocks, single-layer, double-layer, current, voltage, etc.

Generally speaking, electronic components such as "connectors", "connectors", and "terminals" are different application forms of the same

concept. They are based on different application industries, application products and application locations. Commonly known by various

names. In the current connector market, the survival of the fittest and the pursuit of cost performance have led to continuous improvement

of the technical level of high-quality connectors, and some connectors have also been eliminated.
