Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are separated into two major categories: headers and receptacles. Headers, sometimes referred to as pins, stands, or posts, are a set of male-pin connections which are designed to mate with a receptacle connector. Receptacles, also known as sockets, are the female-pin counterparts of headers.

Application Field

Rectangular connectors are used mainly in telecommunications systems, industrial markets, automobiles, solar panels and consumer devices. They are used in networks for high-speed and large volume data flows.Moreover, rectangular connectors can be used for mating to daughter boards, backplanes, flex cable systems and other interconnects.

Rectangular connectors are by far the most used connector family over a wide range of applications such as LAN/WAN equipment, routers, servers, storage equipment, telecom equipment, power supplies, industrial controllers, computers, and more.

Working Principle

The two main components of rectangular connectors:headers and receptacles , both aim to ensure a reliable connection with an electrical system. When the two plastic housing are mated,the electrical contacts come into contact and create an electrical circuit.The principle of conducting relies on the contact elements, which are either metal to metal, copper for gold plating or copper for a nickel barrier.

The Rectangular connectors generally consist of a male pin side and a female receptacle side that can be mated together using a latch. Some of these connectors have locking mechanisms that prevent accidental un-mating, thus providing additional security between the two circuits. The design of the metal contacts must ensure the reliable contact between the two mating parts.

The basic design of rectangular connectors includes two metallic pins that are placed into positions within a plastic housing. This ensures a sound electrical connection while being easy to install and remove. Additionally, most headers and receptacles have similar wiring, with the female connector providing power to the male connector.

Conclusion

Rectangular Connectors - Headers, Receptacles, Female Sockets, are essential for any electrical connection and are popular choices for a variety of applications due to their ease of use, low cost, and various wire paths on a single connector. From consumer electronics to solar energy applications, rectangular connectors are increasingly used to enable reliable and cost-effective data transfer.
