Rectangular connectors, also called Headers, Male Pins, are widely used components in a variety of industries due to their simple structure, standard size, and easy installation. This article introduces the application fields and working principles of these connectors in detail.

Application Fields

Rectangular connectors, or male pins, are mainly used for PCB (Printed Circuit Board) connection and communication. They are widely used in various electronic products such as automobiles, computers, communications, and consumer products, as well as military and industrial applications. Not only applicable to the connection of two PCBs, they are also used for the connection between a circuit board and a module board or an upper and lower cover. The advantages of these connectors are that they are small, lightweight and have a wide variety of applications.

Heat sinks, fans and other related components are usually connected to the power board with rectangular headers. The module boards of cars also have connectors installed on them, mainly for communications between components such as USB, Ethernet, WiFi, and other wired and wireless signals. In addition, rectangular connectors are also used in office automation equipment, medical equipment, office equipment, electronic consumer products and production devices.

Working Principle

The male headers are composed of two parts, namely the terminal and the housing. The housing is a relatively simple component and is usually made of plastic or metal material. It can hold the terminal and the corresponding circuit board according to the size of the terminal. The terminals are the electrical contacts that transmit the current in the circuit, usually made of copper or other conductive materials. The pins in the housing are usually hollow and can be filled with rubber or other materials to keep the terminals in place and to ensure a good electrical connection.

In the actual application process, the rectangular connector is first soldered to the circuit board and then inserted into the corresponding rectangular socket. The terminals of the rectangular socket are equipped with an elastic pressing device, which can firmly grasp each terminal of the male headers. When the connection is completed, the signal is transmitted through the terminals, and the current passes through the terminals of the housing to power the circuit.

Conclusion

Rectangular connectors are a kind of universal and widely used components in the electronics industry. Their simple structure, standard sizes, and easy installation make them suitable for a variety of electric connection applications. This article introduces the application fields and working principles of male pins in detail. With this article, engineers, hardware designers, technicians and other can have a better understanding about rectangular connectors and their various applications.
