Introduction

Rectangular connectors are a type of electrical connector used for joining two cables, cords, or other components. They are commonly found in both commercial and residential applications, providing a safe and reliable way to transmit electrical energy. There are a wide variety of rectangular connectors available, including headers, receptacles, and female sockets.

Headers

Headers are rectangular connectors with two or more contacts on a single row, which can be connected together with wire or a jumper. They are commonly used in computers for data and power transmission, such as in USB cables. Headers can also be used in other applications, such as industrial equipment, lighting, audio/video, and consumer electronics.

Receptacles

Receptacles are rectangular connectors with two or more cavities that can house various pins, blades, or other contacts. They are commonly used in power distribution, such as connecting an appliance’s power cord to a wall outlet. Receptacles are also commonly used in industrial control systems and other applications requiring various types of signal or power connections.

Female Sockets

Female sockets are rectangular connectors with multiple contacts on one side that fit over blades, pins, or other device contacts. They are often used in data, audio/video, and other applications requiring a secure connection. Female sockets can also be used in power distribution, providing a reliable connection for high-current applications.

AR Application Field and Working Principle

AR connectors, also known as AR headers, are a type of rectangular connector specifically designed for military and aerospace applications. These connectors are characterized by their robust construction and high current, power, and voltage ratings, making them ideal for applications requiring a reliable connection in extreme conditions. They are frequently used in avionics, radar systems, satellites, and various other control systems.

AR connectors feature an integral locking mechanism that can help to reduce signal loss and enhance transfer efficiency. The primary components of an AR connector are the male and female rectangular elements, which feature several blade connectors and blades that are mated together using built-in, interlocking lids. Once mated, these two elements provide a secure connection and help to prevent accidental disconnection, making them ideal for high-durability applications.

AR connectors also feature contacts that are plated with corrosion-resistant nickel and gold to ensure a long-lasting connection over time. In addition, AR connectors feature a waterproof design to protect against dust, dirt, and moisture. This helps to ensure a reliable connection even in the toughest of environments.

Conclusion

Rectangular connectors are widely used in a variety of applications and offer many advantages over other types of connectors. Headers, receptacles, and female sockets provide a reliable connection for transmitting and distributing power, as well as for carrying data signals. And AR connectors are specifically designed for military and aerospace applications, featuring robust construction and high current, power, and voltage ratings.

No matter the application, rectangular connectors provide a safe and reliable way to transmit and distribute electrical energy.
