Connectors are electronic components that connect the flow of electricity and electrical signals.
Connectors usually refer to electromechanical components that connect conductors (wires) to appropriate mating components to connect and disconnect current or signals. They serve as electrical connections between devices and components, components and mechanisms, systems and subsystems. and signal transmission devices. Also known as connectors, plugs and sockets, they were born from the manufacturing techniques of fighter jets. Aircraft in battle must be refueled and repaired on the ground, and the time spent on the ground is an important factor in the outcome of a battle.

From the perspective of the connection function achieved, the connector can realize the connection between printed circuits, backplanes, equipment, etc. The main implementation methods are divided into four categories: first, the connection of IC components or components to printed circuit boards, typically such as IC sockets; second, the connection of printed circuit boards to printed circuit boards, typically such as printed circuit connectors; third The first is the connection between baseboards, typically such as cabinet-type connectors; the fourth is the connection between equipment and equipment, typically such as circular connectors. The highest market shares are products for printed circuit board interconnection and device interconnection.
Connectors are easy to mass produce, easy to repair, easy to upgrade, and improve design flexibility. They are widely used in aerospace, communications and data transmission, new energy vehicles, rail transit, consumer electronics, energy, medical and other fields. The rapid development of product technology in application fields and the rapid growth of the market have strongly driven the development of connector technology. So far, connectors have developed into serialized and specialized products with complete product categories, rich varieties and specifications, diverse structural types, professional direction subdivisions, obvious industry characteristics, and standard system specifications.

Connectors support connectors in various fields of modern society. Next, we introduce the functional characteristics of connectors and the technology and production processes that support them.

Connector usage areas
Connectors are not only used in smartphones, computers and other items that are closely related to our lives, but also have a wide range of applications in all electronic-related terminal equipment. Because connectors need to cope with various design styles and uses, there are many types of connectors. What kind of connection effect will be produced by using connectors? Let’s take a computer as an example to illustrate.

First, there are the memory slots. It is mounted on the PCB board in the computer case and is used to connect the memory card to the slot.
Secondly, it is a connector used on the PCB board inside the computer. The circuit is composed of multiple PCBs according to different functions. Connectors are required to connect these PCBs. In addition, connectors are also needed to connect the LCD screen and keyboard to the PCB board.
Finally there are the IO connectors. This is a connector used to connect computer hosts and printers, mobile devices, televisions, etc. to external devices.
In addition, there are card holder connectors for connecting various cards, such as SD card holders.

Advantages and Necessities of Connectors
So, why do you need to use connectors?
For example, when connecting the internal PCB board of the equipment, although the circuit can be connected directly, this will require a long working time. Moreover, disassembly and other work during repairs are time-consuming. But using connectors to connect, you can quickly and easily “connect” and “detach” them. Therefore, mass production, division of labor production, repair and maintenance work can be easily realized. The interface between peripheral machinery and the network is naturally the same. With the evolution of various devices, the convenience of “connection” and “detachment” of connectors is indispensable.

Connector construction accessories
So, what is the structure of the connector?
The connector is composed of a plug and a socket and functions as a pair. Plugs and sockets are composed of energized terminals, an insulator made of plastic to maintain the insulation function between the terminals, and shell parts to protect it.
The most critical terminal in the connector component is made of copper alloy material with high electrical conductivity. One side is an inelastic plug terminal, and the other side is a socket terminal processed with an elastic structure, which can tightly combine the plug and the socket. The jack is brought into contact with the plug, and the elastic structure of the connector is used to make it fit tightly, completing the connection or transmitting power and signals.
