1、 First, distinguish the conceptual differences between "connector", "wiring terminal", and "connector"
① Connector, also known as CONNECTOR. Also known as plug-in connectors. It is a component that electronic engineering technicians often come into contact with. Also known as connectors, plugs, and sockets in China. Generally refers to electrical connectors. A device that connects two active devices to transmit current or signals.
② A connector is a positioning connector that connects electronic circuits, consisting of two parts: a connector and a connector. Generally, they can be completely separated. The similarity between a switch and a connector is that they change the contact state of their contact pairs to achieve the purpose of converting the circuit they are connected to. The essential difference is that the connector only has two states: insertion and removal, and the switch can convert the circuit on its body, However, connectors cannot achieve conversion on the ontology, and there is a fixed correspondence between the contact pairs of connectors. Therefore, connectors can also be called connectors.
③ Terminal, also known as Terminal in English. It is a type of accessory product used to achieve electrical connections, which is classified as a connector in industry. Terminal blocks are used for the convenience of connecting wires. They are actually a piece of metal enclosed in insulating plastic, with holes at both ends for inserting wires. Wiring terminals can be divided into WUK wiring terminals, European wiring terminal series, plug-in wiring terminal series, etc.
2、 Distinguish between "connectors", "wiring terminals", and "connectors" based on their scope of ownership
① "Connector=connector" is the first major category, and wiring terminals are just one type of "connector" category
What is the difference between connectors and connectors?
A connector is a connection between wires; A connector is a connection between wires, boards, and boxes. In real life, people often refer vaguely to the same thing.
② The terminal is part of the connector. A connector is a general term, which usually includes two parts: a housing and a terminal. Housing is mostly made of plastic for protective purposes, while terminal is made of metal for conductivity purposes.
③ In the field of electricians and electrical engineering:
Connectors, connectors, and connectors are the same product. Simply put, it is the type of thing that can be quickly connected to a male or female head with just one insert or twist of the hand without the need for tools.
Terminal blocks, in layman's terms, are the type of devices that require tools such as screwdrivers and cold press pliers to connect two components together. They are generally used for power input and output. The English name is Terminal.
3、 Distinguish the practical applications of "connectors", "wiring terminals", and "connectors"
Electrical connectors, also known as connectors or connectors, are a sub field of electronic components mainly used for connecting circuits. In industrial production, line connections can be said to be ubiquitous, so the range of use of connectors is certainly very wide, applied in various industries.
There are many specific categories of connectors, such as rectangular connectors, circular connectors, stepped connectors, etc. Terminal blocks are a type of connector, generally belonging to rectangular connectors. The scope of use of terminal blocks is also relatively limited, generally used in the field of electronics and electrical engineering, for the internal and external wiring of PCB circuit boards, printed boards, and distribution cabinets.
The use range and variety of wiring terminals are increasing. At present, the most widely used terminals are not only PCB board terminals, but also hardware terminals, nut terminals, spring terminals, etc. In the power industry, there are specialized terminal blocks and terminal boxes, all of which are wiring terminals, single-layer, double-layer, current, voltage, ordinary, interruptible, etc.
Overall, "connector", "terminal block", and "connector" are different forms of application that belong to the same concept, and are commonly referred to according to different practical applications.
