What Are The Differences Between Connectors, Terminal Blocks, And Heavy-duty Connectors?
1. Conceptual differences
①Heavy Duty Connector. It is a component that electronic engineering technicians often come into contact with. It is also called heavy duty 12 volt connectors, plug, and socket in China. It generally refers to 12v heavy duty connector. That is, a device that connects two active devices to transmit current or signals.
②heavy duty crimp connectors is a heavy duty waterproof electrical connectors that connects electronic circuits. It consists of two parts, namely the plug-in and heavy duty 2 pin connector. Generally, it can be completely separated. The similarity between the switch and the heavy duty connector 16 pin is that the change in the contact state of its contact pair realizes the purpose of the circuit connected by the switch. The essential difference is that the heavy duty connector 5 pin can only be plugged in and out, the switch can realize circuit switching on its main body, and the connector cannot realize switching on the main body. There is a fixed correspondence between the contact pairs of the connector.
③Terminal, English name Terminal. It is an accessory product used to realize electrical connection, which is classified as a connector in industry. Terminals are used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic, with holes at both ends, into which the wires can be inserted. Terminals can be divided into WUK terminals, European terminal series, plug-in terminal series, etc.
Second, distinguish from the scope of ownership.
① "Connector = connector" is a category, and the terminal is just one of the categories of "connector". The connector is the connection between the lines; it is the connection between the connector and the circuit board and the box. In practice, it is often classified into one category.
② The terminal is part of the connector. Connector is a general term. In fact, common connectors usually include two parts: the shell and the terminal. The shell is mostly plastic, which plays a protective role, and the terminal is metal, which plays a conductive role.
③ In the field of electrical engineering and electrical engineering:
Connectors, connectors and connectors are the same product. Generally speaking, it is something that can be quickly connected by inserting or twisting the male and female heads by hand without tools.
Terminals, in a popular understanding, are things that require tools, such as screwdrivers and cold press pliers, to connect two things together. Generally used for power input and output. The English name is Terminal.
Third, the difference in practical applications
Electrical connectors, referred to as connectors, are a subdivision of electronic components, mainly used for connections between circuits. In industrial production, line connections can be said to be ubiquitous, so the scope of use of connectors is of course very wide, and they are used in various industries.
Connectors can be divided into many categories, such as rectangular connectors, circular connectors, stepped connectors, etc. Terminal blocks are a type of connector, generally belonging to rectangular connectors. The application range of terminals is relatively simple, generally used in the field of electronics and electrical, for internal and external connections of PCBs, printed boards, and distribution cabinets.
The applications and types of terminals are increasing. At present, in addition to PCB terminals, there are also hardware terminals, nut terminals, spring terminals, etc. It is widely used. In the power industry, there are special terminal blocks and junction boxes, all of which are single-layer, double-layer, current, voltage, ordinary and easy-to-break terminals.
Generally speaking, "connector", "terminal block" and "connector" are different application manifestations of the same concept, named according to different practical applications.
