1. Connectors, also called pin and socket connectors. They are a component that electronic engineering technicians often come into contact with. In China, they are also called pin and socket, plug and socket. They generally refer to electrical connectors. That is, devices that connect two active devices to transmit current or signals.

2. Connector pin are accessories used to achieve electrical connections, which are industrially classified as connectors. connector pin are used to facilitate the connection of wires. They are actually a piece of metal sealed in insulating plastic with holes at both ends for inserting wires. connector pin blocks can be divided into WUK connector pins, stretch connector pin series, plug-in connector pin series, etc.

3. Pin and socket are positioning connectors for connecting electronic circuits. They are composed of two parts, namely plug-ins and connectors. Under normal conditions, they can be completely separated. The similarity between switches and pin and socket is that the purpose of converting the connected circuit is achieved by changing the contact state of their contact pairs. Therefore, pin and socket can also be called connectors.

Distinguish connectors, connector pin blocks, and pins and sockets in terms of their scope:

1. "Connector = pins and sockets" is the first category, and connector pin blocks are just one of the "connector" categories.

2. Connector pins are part of connectors. Connector is a general term. In fact, the connectors we often see usually include two major parts: plastic shell and connector pin. The plastic shell is mostly plastic and plays a protective role, while the connector pin is metal and plays a conductive role. Distinguish connectors, connector pin blocks, and pins and sockets in actual application:

Electrical connectors are referred to as connectors, also called pins and sockets. They are a subdivision of electronic components and are mainly used for connections between circuits. In industrial production, line connections can be said to be everywhere, so the scope of use of connectors is of course very wide and is used in various industries.
