The electronic industry often uses the words connector, connector and terminal, which have their own characteristics and uses:

Connector: A connector is a component that connects two devices or electronic circuits so that current or signals can flow from one device to the other. Connectors can be designed in various ways, including circular and rectangular shapes, and are usually detachable to facilitate the connection and disconnection between devices. There are many kinds of connectors, such as USB connectors and audio plugs.

Plug-in usually refers to the combination of PlugandSocket for electrical connection. A plug is a part of a plug-in and can be inserted into another part, namely a socket, to establish an electrical connection. This connection is usually used to transmit power or signals. In daily life, our common power plugs and sockets are examples of connecting plug-ins.

Terminal: A terminal is an electrical component used to connect wires, which provides a convenient method for connecting wires. Terminals can be simple screw terminals or more complex types, such as spring-loaded terminals. Terminals are usually used to fix and protect wires to ensure the stable connection of wires.

To sum up, connector is a broader concept and can be used for various types of electrical connections. Connector refers to the combination of plug and socket, which is mainly used to establish and disconnect the connection. Terminals are specific parts for connecting wires, which are usually used for fixing and connecting wires.
