What is the difference between the connector and the socket and the terminal block?

For those who have just started to contact the connector, the concept difference between the "connector", "socket" and "terminal" may not be known in the early stage.

The difference between the three:

First, distinguish the difference between "connector", "socket" and "terminal" from the concept

1. Connectors are a large class, a component that electronic engineering technicians often touch. Most of them refer to electrical connectors that connect two electronic components with components to transmit current or signals.

2. The socket is a positioning joint for connecting electronic circuits. It is composed of two parts. The plug and the connector can be completely separated under normal conditions, so the socket can also be called a connector.

3. The terminal block is a kind of accessory product used to realize electrical connection. It is applied for the convenience of connecting the wires. In fact, it is a piece of metal sealed in an insulating plastic with holes at both ends for inserting wires. The terminal blocks can be divided into plug-in type terminals and European-style terminals.

Second, distinguish the difference between "connector", "socket" and "terminal" from practical applications

1. Electrical connectors are referred to as connectors, also called sockets, and are a subdivision of electronic components, mainly used in the connection between circuits and circuits. In the current electronic industry production, the connector connection of the connector can be said to be ubiquitous, so the connector is widely used, and can be applied indirectly in various industries.

2. There are many types of connector specific classifications, such as rectangular connectors, stepped connectors, circular connectors, and the like. The terminal block is a kind of connector, generally belongs to a rectangular connector, and the terminal block is also used in a single range, and is generally used in the field of electronic and electrical, and is used for connecting internal and external lines of PCB circuit boards, power distribution cabinets, and printed boards. .

3. The use of terminal blocks is increasing, and the types are increasing. In addition to the PCB board terminals, there are also the most widely used hardware terminals, spring terminals, nut terminals and so on. In the power industry, there are special terminal blocks, terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, and so on.

In general, the electronic components of "connector", "socket" and "terminal" are different application expressions belonging to the same concept, which are popular according to different application industries, application products and application locations. It is called a variety of different names. The current connector market is the survival of the fittest, and the pursuit of cost-effectiveness has made the quality of high-quality connector technology continue to improve, and some connectors are being eliminated.

Third, distinguish the difference between "connector", "socket" and "terminal" from the scope of attribution
