What Are The Concepts, Scopes And Application Differences Of Connectors, Terminal Blocks And Heavy-duty Connectors?

Here is a detailed introduction to the differences between the three:

1. First, distinguish the conceptual differences between heavy duty electrical contacts, terminal blocks and heavy duty industrial connector. See the technical article sharing for details. Please click heavy duty male female connector, terminal blocks and heavy duty multi pin connectors.

①heavy connector, that is, CONNECTOR. Also known as heavy duty cable connectors. It is a component that electronic engineering technicians often come into contact with. In China, it is also called heavy power connector, plug and socket. It usually refers to an electrical connector. That is, a device that connects two active devices to transmit current or signals.

②The connection plug-in is a positioning connector that connects electronic circuits, consisting of a plug-in and a connector. Generally, it can be completely separated. The similarity between switches and connectors is that the purpose of the connector's conversion is to achieve the purpose of converting the connector circuit through. The essential difference is that the plug-in has only two states of insertion and removal. The switch can realize the conversion of the body circuit, while the connector cannot realize the conversion of the body.

③Terminal, English name Terminal. It is an accessory product used to achieve electrical connection, which is divided into connector categories in industry. Terminal blocks are used to facilitate wire connection. In fact, it is a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires. Terminal blocks can be divided into WUK terminal blocks, European terminal block series, plug-in terminal block series, etc.

2. Distinguish connectors, terminal blocks, and plug-in connectors from the scope of belonging

① Connector = Connector is a category, terminal block is just a type of connector in the connector category. What is the difference between connectors and connectors?

Connectors are the connection between wires; connectors are the connection between wires and boards and boxes. In real life, people often refer to the same thing vaguely.

② Terminals are part of connectors. Connectors are a general term. In fact, the connectors we often see usually include plastic shells and terminals. Housing is mostly plastic, which plays a protective role. Terminal is metal, which plays a conductive role.

③ In the field of electrical engineering and electrical engineering: connectors, plug-ins, and plug-ins are the same product. Generally speaking, it is a kind of thing that can be quickly connected without tools, common heads and mother heads, and can be inserted or tightened by hand. Generally speaking, terminal blocks refer to things that require tools, such as screwdrivers and cold-pressing pliers, and are usually used for power input and output. The English name is terminal.

3. Distinguish connectors, terminal blocks, and connectors. Practical application of electrical connectors is called connectors, also known as connectors. It is a subdivision of electronic components and is 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. Connectors are specifically divided into rectangular connectors, circular connectors, trapezoidal connectors, etc. Terminal blocks are a type of connector, generally belonging to rectangular connectors.

The scope of use of terminal blocks is also relatively single. They are generally used in the field of electronics and electrical, and are used for internal and external connections of PCB circuit boards, printed boards, and distribution cabinets. The scope of use of terminal blocks is increasing, and there are more and more types. At present, in addition to PCB board terminals, there are also hardware terminals, nut terminals, spring terminals, etc. In the power industry, there are special terminal blocks and terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, ordinary, breakable, etc. Generally speaking, connectors, terminal blocks, and connectors are all concepts of different application expressions, and they are popular according to different actual applications.
