What are the conceptual differences among terminal blocks, connectors, and plugs?
A connector is a positioning joint used to connect electronic circuits. It consists of two main parts: the plug and the socket, which can usually be completely separated from each other. Like switches, connectors achieve circuit switching by altering their contact states. The essential difference, however, is that connectors have only two states—inserted and removed—and cannot perform circuit switching directly within their own body, whereas switches can switch circuits right on their own body. The contacts of a connector maintain a fixed, corresponding relationship with each other.

1. Terminal block
Born out of the need for convenient wire connections, this is a component product designed to facilitate electrical connections. It consists of a metal conductor encased in an insulating plastic housing, with holes at both ends that allow wires to be inserted.
For example, suppose you have two wires that sometimes need to be connected and other times need to be disconnected. In such cases, you can use terminal blocks to connect them—and you can disconnect them at any time without having to solder or wrap them together. It’s convenient and quick.
2. Connector
Also known as connector plugs, these are components frequently encountered by electronic engineering technicians. They are also referred to as plugs and sockets and generally refer to electrical connectors—devices that connect two active components to transmit current or signals.
