Rectangular Connectors - Headers, Male Pins, such as 451-10-238-00-005000 connector, are ubiquitous in modern electrical and electronic applications, from lighting fixtures to communications equipment and automotive systems. These robust connectors are designed to make terminating and interconnecting wire harnesses easier and more reliable. To understand how and why these connectors are so widely used, it is important to understand their application field and working principle.

Application Field

Rectangular Connectors - Headers, Male Pins, such as 451-10-238-00-005000, are commonly used in automotive, industrial control, and medical equipment applications. Their precise design, low contact resistance, and reliable interconnections make them perfect for operating conditions with shocks, vibration, and heat. For example, they are often used to connect switches, sensors, controls, and other signals in automotive engine control systems.

Rectangular Connectors are also widely used in commercial electronic equipment, such as computers, communication systems, and audio/visual equipment. They provide reliable connections with a minimum of wiring, enabling smaller, lighter, and more efficient products. The same qualities make them attractive for use in consumer electronics products such as TVs, radios, stereo systems, and mobile phones. Because of their superior performance, Rectangular Connectors are also frequently used in aerospace and military applications, where their robust design and high reliability are essential.

Working Principle

Rectangular Connectors - Headers, Male Pins, such as 451-10-238-00-005000, use a specialized two-piece contact design. Each contact is composed of an insulator housing and a metal contact. The insulator housing provides support for the contact and enables the required circuit layout. The contact is made of an electrically conductive material, such as brass or phosphor bronze, and the contact surface is plated with gold or silver. A spring bias holds the contact in place, providing superior physical and electrical connection.

The contact arrangement of a Rectangular Connector is designed to provide a reliable connection in the presence of vibration, shocks, and static electricity. To ensure a stable electrical connection, the contact insert should fit in the insert opening of the housing. The contact insert should be pressed firmly against the contact spring, thus ensuring a secure electrical connection. Once the contact is fully inserted and locked, the contact spring provides full electrical continuity with minimal resistance.

To ensure the secure connection of a Rectangular Connector, the contact surface must be clean and free of oxide or tarnish. To maintain a secure connection, the contact spring should be checked and serviced periodically. Proper buffing and cleaning of the contact surface helps to minimize contact resistance and current leakage.

Conclusion

Rectangular Connectors - Headers, Male Pins, such as 451-10-238-00-005000, are widely used in a variety of electrical and electronic applications due to their robust design, low contact resistance, and reliable interconnections. These connectors use a specialized two-piece contact design, made of an insulator housing and a metal contact. The contact arrangement is designed to provide a reliable connection in the presence of vibration, shocks, and static electricity. To ensure the secure connection of a Rectangular Connector, the contact surface must be clean and free of oxide or tarnish.
