The difference between connectors, terminals, connector assembly
Understand the difference between "connector", "terminal" and "connector assembly". This article is enough. If you haven't read a similar article before, don't miss it now. As a connector industry practitioner, if the difference between the three is unclear, I am afraid it will be ridiculed.
Some practitioners in the connector industry can't distinguish between the concept of "connector", "terminal" and "connector assembly", the difference in attribution, and the difference in practical application... Konnra electron explains the differences in detail here:
First, distinguish the concept difference between "connector", "terminal" and "connector assembly"
1.Connector, also known as the connector assembly connector. It is a component that electronic engineering technicians often come into contact with. Domestically known as connector assembly, plugs and sockets. Generally refers to electrical connectors. That is, a device that connects two active devices to transmit current or signals.
2.Connector assembly is a kind of positioning joint that connects electronic circuits. It consists of two parts, namely plug-in and connector. Under normal conditions, it can be completely separated. The same thing about switch and connector assembly lies in the contact state of the contact pair. Change, realize the conversion purpose of the connected circuit, and the essential difference is that the plug connector can only be inserted and removed in two states, the switch can realize the circuit conversion on the body, and the connector assembly can not realize the conversion on the body. There is a fixed correspondence between the contact pairs of the connector assembly, so the connector assembly can also be called a connector.
Second, distinguish the "connector", "terminal", "connector assembly" from the scope of attribution
1 "Connector = connector assembly" is the first major category. The terminal block is only the difference between a connector assembly and a connector in the "connector" category. The connector is a wire-to-wire connection; the connector assembly is a wire and a board. The connection to the box. People in real life often blur the same thing.
2.Terminal is part of the connector. The connector is a general term. In fact, the connectors we usually use usually include two parts, housing and terminal. Housing is mostly plastic, plays a protective role, terminal is a metal, which acts as a conduction.
Third, distinguish the "connector", "terminal", "connector assembly" practical application
The electrical connector is simply referred to as a connector, also known as a connector assembly. It is a subdivision of electronic components and is mainly used for the connection between circuits and circuits. In industrial production, the line connection can be said to be ubiquitous, so the range of use of the connector is of course very extensive, and it is applied in various industries.
The connector is divided into many categories, such as a rectangular connector, a circular connector, a stepped connector, etc., and the terminal block is a type of connector, generally belonging to a rectangular connector. The terminal block is also used in a single range, and is generally used in the field of electronic and electrical, and is used for connecting internal and external wiring of PCB circuit boards, printed boards and power distribution cabinets.
The use of terminal blocks is increasing and the variety is increasing. At present, in addition to PCB board terminals, there are also hardware terminals, nut terminals, spring terminals, etc. In the power industry, there are special terminal blocks, terminal boxes, all of which are terminal blocks, single-layer, double-layer , current, voltage, normal, breakable, etc.

3.Terminal block - Terminal terminal. It is an accessory product for electrical connection, which is industrially divided into connectors. The terminal block is used to facilitate the connection of the wire. It is actually a piece of metal that is sealed inside the insulating plastic. There are holes at both ends to insert the wire. The terminal blocks can be divided into WUK terminal blocks, European terminal blocks series, and plug-in terminal blocks.

3 In the electrical and electrical fields: connectors, connectors, connector assembly are the same product. Generally understood, it is the kind of thing that can be quickly connected by a male or female head with a tool or a screw. The terminal block, which is commonly understood, is the kind of thing that needs to be connected with two tools by a tool such as a screwdriver or a cold press pliers, which is generally used for power input and output.

In general, the "connector", "terminal" and "connector assembly" are different application expressions belonging to the same concept, and are commonly referred to according to different practical applications. The differences between "connectors", "terminals" and "connector assembly" are introduced here. To learn more about the technical aspects of connectors, please visit our industry news.
