When it comes to the variety of connectors used in electrical engineering, few products offer unmatched versatility and reliability as the 87224-4. This 3-pin rectangular connector, also known as a header connector, is designed for applications where durability is critical and high-performance to survive harsh environments. With its versatile design and low contact resistance, 87224-4 connectors have become a popular choice in a wide range of industrial and military applications. In this article, we will explore the various features and applications of 87224-4 connectors, as well as their common construction and working principle.

Overview of 87224-4 Rectangular Connectors

87224-4 connectors are 3-pin rectangular header connectors that are commonly used in a variety of industrial and military applications. The connectors feature a versatile design with a rugged, durable construction that is designed to withstand the rigors of harsh environments. The connectors feature three straight-wire contacts that are either screw-in or push-in type, depending on the application. The connectors also feature a low-contact-resistance rating of 40 milliohms, allowing them to maintain a secure signal connection while providing excellent durability and reliability. Additionally, 87224-4 connectors are designed with a keyed mating system that makes it easier to install and remove.

Construction and Working Principle of 87224-4

The construction of 87224-4 connectors features a molded plastic body with an internal ground plane. The body is designed with cutouts for two spring-loaded retention clips that hold the connector in place, ensuring a secure connection that can withstand the rigors of harsh conditions. The three straight-wire contacts are soldered to the internal ground plane at the back of the connector, allowing for optimal connection. The contacts are also designed with a step-down structure, which allows them to remain securely in place despite shocks and vibration.

The working principle of 87224-4 connectors is simple, yet effective. At one end, the pins of the connector are inserted into the corresponding entry points of the mating device. Once the pins are firmly in place, the mating device\'s contacts are then soldered to the internal ground plane at the back of the connector. This ensures a strong connection between the 87224-4 connector and the mating device, allowing for a reliable and durable signal connection.

Common Applications and Features of 87224-4

Due to their rugged construction and low contact resistance rating, 87224-4 connectors are commonly used in a wide variety of industrial and military applications. Their versatility make them ideal for use in applications such as industrial control panels, automotive diagnostic systems, and even some medical equipment. Additionally, 87224-4 connectors are designed to meet the demanding requirements of the MIL-DTL-83723 specification, ensuring that they can be relied on in the most extreme and hazardous environments.

87224-4 connectors also feature a unique keyed mating system designed to make installation and removal easier. The keyed system, which is designed into the connector, ensures that the plug is inserted into the mating device correctly, reducing the risk of incorrectly wired connections. Additionally, 87224-4 connectors feature a unique "Push-On" design that allows for quick and easy installation without the need for soldering.

Conclusion

The 87224-4 is a popular 3-pin rectangular header connector used for a variety of industrial and military applications. Its rugged construction and low contact resistance make it an ideal choice for harsh environments, while its versatile design allows it to meet the demanding requirements of the MIL-DTL-83723 specification. The connector also features a unique keyed mating system that makes installation and removal easier. With its versatile design and low contact resistance, 87224-4 connectors have become a popular choice for a wide range of applications.
