What is the conceptual difference between terminal blocks, plastic connectors and connectors?

1. Wiring terminal

In order to facilitate wiring, it came into being as an accessory product to realize electrical connection. The metal conductor is encapsulated in an insulating plastic part, with holes at both ends, into which wires can be inserted.

For example, if there are two wires, sometimes they need to be connected and sometimes they need to be disconnected. At this time, they can be connected and disconnected at any time through the terminals, which is very convenient and quick, without welding or twisting them together.



2. Plastic connector also known as connector connector, is a component that electronic engineering and technical personnel often touch. Also known as plugs and sockets, they generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals.

3. Plastic connector

The connector is a positioning connector used to connect electronic circuits. It consists of plug-ins and connectors, which can usually be completely separated. The connector is similar to a switch, it can realize the conversion of the connected circuit by changing its contact state. The essential difference is that the connector has only two states of plugging and unplugging, and cannot be converted on the main body, while the switch can realize the circuit conversion on the main body. There is a fixed correspondence between the contacts of the connector.
