1. The concept of distinguishing between connectors, terminals and connectors:

1. Connector, also called connector connector. It is a component often contacted by electronic engineering technicians. It is also called connector, plug and socket in China. Generally refers to electrical connectors. That is, a device that connects two active devices and transmits current or signals.

2.Terminal is a kind of accessory product used to realize electrical connection. It is industrially divided into the category of connector. The terminal is used to facilitate the connection of the wires. It is actually a piece of metal sheet enclosed in an insulating plastic. There are holes at both ends to insert the wires. Terminal blocks can be divided into WUK terminal blocks, tensile terminal blocks, plug-in terminal blocks and so on.

3. The connector is a positioning connector for connecting electronic circuits. It consists of two parts, namely the plug and the connector, which can be completely separated under normal conditions. The same thing between the switch and the connector lies in the contact of the contact The change of state achieves the purpose of switching the connected circuit. Therefore, the connector can also be called a connector.

2. Differentiate connectors, terminals, and connectors on the scope of attribution:

1, "connector = connector" is the first category, and the terminal is only one of the "connector" category.

2, the terminal is part of the connector. Connector is a general term. In fact, the connector we commonly see usually includes two parts: rubber shell and terminal. The plastic shell is mostly plastic, which plays a protective role, and the terminals are metal, which is universal.

Three, the actual application of connectors, terminal blocks, connectors are distinguished:

Electrical connector is short for connector, also called connector, is a subdivision field of electronic components, mainly used for the connection between circuits. In industrial production, line connections can be said to be ubiquitous, so the range of use of connectors is of course very wide and is used in various industries.

The range of use of terminals is more and more, and more and more types. At present, Dongguan Heju Precision PCB terminal, hardware terminal, precision terminal, motor terminal, connector terminal, relay terminal, terminal on audio and electronic components, etc. The box is full of terminal blocks, single layer, double layer, current, voltage, ordinary, breakable and so on.
