In its essence, the connector consists of two parts, namely the plug and the connector. Usually, the connector can be completely separated.

The connector is a relay station in the circuit harness.

The connector generally refers to the connection unit between various electronic components. Although the scope of the connector has not been clearly defined, it usually does not include electrical high voltage, high current electrical appliances or electrical connectors, and electrical switches are not included.

In Japan, most people in the industry directly use Connectoer's transliteration, sometimes called serials.

Connectors are also called connectors. Also known as connectors and sockets in China, generally refers toElectrical connector. That is, a device that connects two active devices to transmit current or signal.

The basic performance of the connector can be divided into three categories: mechanical performance, electrical performance and environmental performance. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095. It takes one insertion and one extraction as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle is used as the judgement basis.

Terminals are a kind of accessory products used to realize electrical connections, which are industrially classified as connectors. With the increasing degree of industrial automation and stricter and more precise requirements for industrial control, the amount of wiring terminals has gradually increased. With the development of the electronics industry, the scope of use of terminal blocks is increasing, and there are more and more types. In addition to PCB terminals, the most widely used terminals include hardware terminals, nut terminals, spring terminals and so on.

The terminal block is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert the wires. There are screws for fastening or loosening, such as two wires. Sometimes Need to connect, sometimes need to disconnect, then you can use the terminal to connect them, and can be disconnected at any time, without having to weld or twist them together, very convenient and quick. Moreover, it is suitable for a large number of wire interconnections. In the power industry, there are special terminal blocks and terminal boxes, all of which are connected terminals, single-layer, double-layer, current, voltage, ordinary, breakable, etc. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass.
