What is the difference between connectors, terminals, and pin jacks?

　　The concept distinction of connectors, terminals, and pin jacks:

　　1. Connector, also called pin jack connector. It is a component that electronic engineering technicians often touch. Also known as pin jacks, plugs and sockets in China. Generally refers to electrical connectors. That is, a device that connects two active devices, carrying current or a signal.

　　2. Terminal is an accessory product used to realize electrical connection, which is divided into the category of connector in industry. The terminal 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, and wires can be inserted. Terminals can be divided into WUK terminals, stretch terminal series, plug-in terminal series and so on.

　　3. The pin jack is a positioning connector for connecting electronic circuits. It is composed of two parts, namely the plug-in and the connector, which can be completely separated under normal conditions. The change of the contact state of the contact pair realizes the conversion purpose of the connected circuit. Therefore, the pin jack can also be called a connector.

　　Distinguish connectors, terminals, and pin jacks in the scope of attribution:

　　1. "Connector = pin jack" is the first category, and the terminal block is only one of the "connector" categories.

　　2. The terminal is part of the connector. Connector is a general term. In fact, the commonly seen connectors usually include two parts: plastic shell and terminal. The plastic shell is mostly plastic, which plays a protective role, and the terminal is metal, which is used for conduction. The practical application distinction of connectors, terminals, and pin jacks:

　　Electrical connectors are referred to as connectors, also known as pin jacks, which are a subdivision of electronic components and are mainly used for the connection between circuits. In industrial production, line connections can be said to be ubiquitous, so connectors are of course widely used in various industries.

　　The use of terminal blocks is increasing, and there are more and more types. Precise PCB board terminals, hardware terminals, precision terminals, motor terminals, connector terminals, relay terminals, terminals on audio and electronic parts, etc. In the power industry, there are special terminal blocks and terminal boxes, all of which are terminal blocks and single-layer terminals. , double layer, current, voltage, normal, can be broken and so on. Dongguan Jingcheng Industry provides various types of pin jack connection application solutions, including connector pin jacks, spring clips, pick and place pads and pogo pins. Our battery connector products include shrapnel, floating battery interconnect system (FBIS) and pogopin, with a variety of options to meet the changing needs of smartphones.
