Rectangular Connectors - Headers, Male Pins, is a type of electrical connector most common use with integrated circuits. It has two main units, the Header and the Male Pin, and is designed to allow easy connection and disconnection of two components. This article will discuss the application fields and working principles of this type of connectors.

Application Fields

Rectangular Connectors - Headers, Male Pins are most commonly used in the automotive, medical, military, and consumer electronics industries. These connectors are used for a wide range of applications including audio and video equipment, automotive electrical systems, communications and networking, computers, data storage, power distribution, printers, and medical equipment. In addition, headers and male pins are also used to join motherboards and daughterboards, mechanical parts and PCBs, and provide electrical connections between components.

Working Principle

The rectangular form factor of these connectors allows them to be easily attached and disconnected from any size female socket or male pin. The Header is the larger of the two units and consists of plastic pins and receptacles called “header pins” or “headers”. The pins on the header are generally terminated with metal contact spring fingers that provide electrical contact when the header is inserted into a mating socket or male pin. The pins are then locked in place by latches, screws, and other locking mechanisms.

The Male Pin is the smaller of the two units and typically consists of metal contacts and spring fingers. When the male pin is inserted into the header, the contacts on the male pin will press against the contacts of the header and form an electrical connection between the components. The contacts are held in place either by latching mechanisms or spring tension.

In addition to these two main components, rectangular connectors may also include additional components such as terminal blocks, junction blocks, and other accessories. Terminal blocks are used to provide power to the header and male pin, while junction blocks connect the header and male pin together to form one complete unit. These additional components can provide additional features such as increased electrical contacts, increased current carrying capacity, signal recovery, or ground connections.

Conclusion

Rectangular Connectors - Headers, Male Pins are an important type of electrical connectors with a wide range of applications in various industries. They are easy to attach and disconnect, and provide reliable electrical connections between two components. In addition to the two main units, a variety of additional components may be used to provide additional features. This article has discussed the application fields and working principles of this type of connector.
