Rectangular Connectors (also known as Headers, Receptacles, Female Sockets) are a type of connector commonly used in electronic applications. The 76342-422LF model is a widely used example, used in connection and power applications. This article outlines the application field and operation principles of this product.

Application Field

The 76342-422LF model is most widely used for power and connection applications. It is designed to offer a secure, reliable connection. This means it can be used in a variety of applications, including:

• Low-voltage PCB connections
• High-density PCB connections
• Interconnections between main power and main control boards
• High-voltage power connections
• Data connections between different electronic devices

The 76342-422LF is also ideal for applications where cost and space are key considerations. It features a low profile design, light weight, and offers excellent cost-to-performance ratio.

Due to its relatively small size (25.4mm x 15.24mm), it is often the recommended choice for tight-fitting, confined spaces; particularly where larger connectors would be impractical. The 76342-422LF is therefore often the go-to option for applications such as hand-held devices.

Working Principle

The 76342-422LF model works by providing two points of contact for a secure electrical connection. It is made up of two parts; the receptacle which has female pins, and the header, which has male pins. When the pins on the header and receptacle are aligned, a secure connection is made — this is the basis of the product\'s working principle.

The header and receptacle have \'teeth\' which securely latch together when in place, and the receptacle\'s plastic housing seals off the connection from external elements, preventing any interference from dust particles or moisture. The header also features embossment for positive lock ensuring a reliable connection.

This connector system can be produced with a range of different pitches, depending on the application. For example, when used in a small, hand-held device, a 0.5mm pitch may be preferred for the tightest fit possible. For power applications, a 2.54mm pitch may suffice.

To ensure the strongest connection, the receptacle material is made of UL 94V-0 rated natural Polypropylene while the header is made of Copper Alloy with gold plated contacts. This combination ensures a strong, corrosion-resistant connection with excellent electrical performance.

The 76342-422LF is designed with durability in mind, and is rated for use up to 3A, 250V and 10,000 cycles. The gold plated contacts and corrosion-resistant design ensures the component can be relied on for a long life of reliable service.

These features, combined with the product\'s low-profile, lightweight design make it the obvious choice for cost-sensitive applications where a secure connection is needed in a confined space.

To conclude, the 76342-422LF Rectangular Connector is a widely used product offering a strong, reliable connection with excellent electrical performance. It is often the go-to choice for applications where cost and space are key considerations. Its two-point contact system ensures a secure electrical connection in a wide variety of application areas, while its gold plating and corrosion-resistant materials ensure a long life of reliable service.
