What is the conceptual difference between terminal blocks and connectors?

1. Terminal blocks

In order to facilitate wire connection, it is a kind of accessory product used to realize electrical connection. It is to encapsulate the metal conductor in the insulating plastic part, and both ends have holes for inserting the wire.

For example, if there are two wires that sometimes need to be connected and sometimes need to be disconnected, then they can be connected with terminal blocks and can be disconnected at any time without welding or winding them together, which is very convenient and fast.

2. Connector

A connector is a positioning connector for connecting electronic circuits. It is composed of two parts: a connector and a connector. Generally, they can be completely separated. The similarities between the connector and the switch are that the purpose of the connected circuit conversion is realized through the change of its contact state. The essential difference is that the connector has only two states of insertion and removal, which cannot realize the conversion on the body, while the switch can realize the circuit conversion on the body. There is a fixed correspondence between the contact of connectors.
