The difference between connectors, plug-in device and terminals.

It is often encountered that some customers confuse connectors, connectors and terminals. Some customers think these three are the same concept. Here I would like to share with you the relevant knowledge of these three so that you can understand them more clearly. Connections and distinctions.


A. Question: What are the concepts of “connector“, “plug-in device” and “terminal“?


  1. Connectors, generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals (electrical signals or optical signals). Its function is very simple: in an electrical circuit, it creates a communication bridge between blocked or isolated circuits, thereby allowing current to flow and the circuit to perform its intended function.


  1. Plug-in devicerefers to an electrical connector, which is a positioning joint that connects electronic circuits. It consists of two parts: plug-in and connector. Under normal conditions, they can be completely separated, so the plug-in devicecan also be called a connector.


  1. Terminalblocks are supporting products for electrical connections. It is used to facilitate the connection of wires. It’s actually a piece of metal sealed with insulating plastic. There are holes on both ends for plug-in connections. Terminalblocks can be divided into plug-in terminal blocks, European-style terminal blocks, etc.


B. Question: Is there any affiliation between “connector”, “plug-in device” and “terminal”?


  1. Connectorsand plug-in deviceare the first category and are a general term. The difference is that the connector is the connection between wires, and the plug-in device is the connection between wires, boards, and boxes. In life, they are often vaguely referred to as the same type. Products and terminal blocks are one such product.


  1. The three connection methods have a common understanding. Plug-indeviceand connectors are electronic components that can be quickly connected by plugging, unplugging or twisting male and female connectors without using tools. Terminal require the use of some tools, such as screwdrivers, cold press pliers, etc., to connect two connection points in electronic products. They are generally used for the input and output of power supplies.

    C. Question: How are “connector”, “plug-in device” and “terminal” used?


    1. Connectorsare mainly used for connections between circuits. They are the core basic components necessary for electrical connections in circuit systems. The main application areas of connectorsare smart homes, automobiles, communications, computers and peripherals, industry, military and aerospace. With development, the scope of application will become wider and wider, and it is basically used in various industries.


    1. Terminals are currently the most widely used PCB board terminals. In addition, there are hardware terminals, nutterminals, spring terminals, etc. There are many types of connectors, including circularconnectors, rectangular connectors, ladder connectors, terminal blocks, etc. It is generally a rectangular connector. The application range of terminal blocks is relatively simple. Generally used in the electronic and electrical fields, for internal and external connections of PCB circuit boards, printed boards and power distribution cabinets.


    In fact, connectors, plug-in device, and terminals are different application forms of the same concept, and are colloquially called more connector-related industry information and.
