what are the conceptual scope and application differences between connectors, terminals and connectors?

some practitioners who have just entered the connector industry cannot distinguish the conceptual differences between "connector", "wiring terminal" and "connector", the differences in scope of ownership, and the differences in practical applications.

here are the differences between the three:

1. first, distinguish the concepts of "connector", "connector" and "connector"

①connector, i.e. CONNECTOR。 also called connector connector. it is a component that electronic engineering technicians often contact. it is also called connectors, plugs and sockets in china. generally refers to electrical connectors. that is, the device connecting two active devices to transmit current or signals.

②a connector is a positioning connector connecting electronic circuits. it is composed of two parts, namely, the plug-in and the connector. generally, it can be completely separated. the same thing between the switch and the connector is to achieve the purpose of converting the circuit connected to the circuit through the change of the contact state of the contact pair. the essential difference is that the connector only has two states: the plug-in is inserted and removed. the switch can realize the circuit conversion on its body, while the connector cannot realize the conversion on the body. there is a fixed correspondence between the contact pair of the connector. therefore, the connector can also be called a connector.

③terminal, english name Terminal (terminal). it is an accessories product used to realize electrical connections, and is industrially divided into the category of connectors. the wiring terminal is used to facilitate the connection of wires. it is actually a piece of metal sealed in insulating plastic. there are holes at both ends to insert the wires. the terminals can be divided into WUK wiring terminals, european-style wiring terminal series, plug-in and unplugged wiring terminal series, etc.

2. distinguish between "connector", "connector" and "connector" from the scope of ownership

①“connector =connectors are the first category, and terminals are just one of the "connectors" categories.

what is the difference between connectors and connectors?

the connector is the connection between wires and wires; the connector is the connection between wires and boards and boxes. in real life, people often refer to the same thing vaguely.

②the terminals are part of the connector. connector is a general term. in fact, the connectors we usually see usually include rubber shells ( housing） and terminal ( terminal） two parts. housing most of them are plastic, which plays a protective role. terminal it is a metal that acts as a conduction.

③in the electrician and electrical fields:

connectors, plug-ins, and plug-ins are the same product. in layman's terms, it is the kind of thing that can be quickly connected without tools, with the male and female heads inserted or twisted by hand.

in layman's terms, it is the kind of thing that requires tools, such as screwdrivers and cold pressing pliers to connect two things together. it is generally used for power input and output. english name Terminal (terminal).

3. distinguish the actual application of "connector", "wiring terminal" and "connector"

electrical connectors are referred to as connectors, also known as connectors. they 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 the scope of use of connectors is of course very wide and is used in various industries.

connectors are divided into many categories, such as rectangular connectors, circular connectors, step-type connectors, etc. the terminal block is a type of connector, which generally belongs to rectangular connectors. the use range of terminal strips is also relatively simple, and is generally used in the electronic and electrical fields. PCB the internal and external connections of circuit boards, printed boards and distribution cabinets.

the use of terminals is increasing, and there are also increasing types. except for the most widely used ones PCB in addition to the board terminals, there are hardware terminals, nut terminals, spring terminals, etc. in the power industry, there are special terminal strips and terminal boxes, which are all wiring terminals, single-layer, double-layer, current, voltage, ordinary, and breakable.

in general, "connector", "connector" and "connector" are different application forms that belong to the same concept and are commonly referred to according to different practical applications.
