Connector and Terminal Concept and Practical Application Field

Connector and Terminal Concept and Practical Application Field


Yesterday I saw an article about connector connectors and terminals in the connector forum, which caused many readers' questions about the relationship between connectors, connectors and terminals! As a direct supplier of electronic connector manufacturers - KENHON Science and technology, relying on the cooperation experience with many large-scale connector manufacturers at home and abroad, today, we share with you the connector connector and terminal concept, the scope of attribution and practical application areas:


First, distinguish the conceptual difference between "connector", "terminal" and "connector"


1, the connector, that is, CONNECTOR. Also called the connector connector. It is a component that electronic engineering technicians often come into contact with. Domestically referred to as connectors, plugs and sockets. Generally refers to electrical connectors. That is, a device that connects two active devices to transmit current or signals.


2. The connector is a positioning connector for connecting electronic circuits. It is composed of two parts, namely, an insert, and a connector, which can be completely separated under normal conditions. The same place of the switch and the connector is the contact through the contact pair thereof. The change of state realizes 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 thereof, and the connector cannot be realized on the body. Conversion, the contact pair of the connector has a fixed correspondence, therefore, the connector can also be called a connector.


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


Second, distinguish the "connector", "terminal", "connector" from the scope of attribution


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


What is the difference between a connector and a connector? A connector is a wire-to-wire connection; a connector is a wire-to-board connection. In real life, people often blur the same thing.


2. The terminal is part of the connector. Connectors are a general term. In fact, the connectors we usually use usually include two parts: housing and terminal. Housing is mostly plastic, it plays a protective role, terminal is metal, and it is universal.


3. In the field of electrical and electrical:


Connectors, connectors, and connectors are the same product. Generally understood, it is the kind of stuff that can be quickly connected by the male and female hands without a tool.


Terminals, commonly understood, are the kind of tools that can be used to connect two Dongdong tools with tools such as screwdrivers and cold-pressing pliers. They are generally used for power input and output. English name Terminal (terminal).


Third, the practical application of distinguishing "connector", "terminal block", "connector"


The electronic connector is referred to as a connector, also called a connector, and is a subdivision of electronic components, 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 lines of PCB circuit boards, printed boards, and power distribution cabinets.


Wiring terminals are used more and more, and the types are 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.


In general, "connectors", "terminals", and "connectors" are different application manifestations that belong to the same concept and are commonly referred to by different practical applications.
