78280-430

Rectangular Connectors - Headers, Male Pins are widely used in various electronic applications. Among them, the 78280-430 connector is one of the most popular connectors for headers and male pins. This article will discuss in detail the application field and working principle of 78280-430 connectors.

Application Field

78280-430 vertical board-to-board connectors are mainly used in the electronic industry, such as electronic test equipment and automotive transportation. The connector provides easy plug-in/plug-out of electronic boards and devices with its SMT-based design. It is also used for bottom-side connection of mobile phones, electronic cameras, monitors, and other multi-layer mounted PCBs with space limitation.

The 78280-430 connector has an extremely wide range of applications and is suitable for computer peripherals and digital products, such as computers, game consoles, optical disc drives, scanners, and digital cameras.

Working Principle

78280-430 connectors are designed with a two-piece system consisting of a housings and contacts. There are different contact pitches available for these connectors namely 2.54mm, 4.2mm and 2.0mm for those with dual-row halves. The contacts are made from a single piece of heat treated phosphor bronze and feature a 3-finger contact mechanism for reliable electrical connection.

When the two-piece connector is plugged into the PCB, the header contact surface is impossible to move and maintain its position. At the same time, it has a certain clearance for the heat of welding and welding gas. The SMT retention feature provides a positive and self-locking feature that prevents accidental disconnection.

The 78280-430 is also designed with a fully insulated housing which prevents leakage and electric shock when it is plugged in. The connector also has a metal shell which shields it from electromagnetic interference. The outer shell also helps to enhance the shockproof ability of the connector and minimize any kind of dust or other foreign particles from entering into the connector.

Conclusion

78280-430 is a highly used connector for headers and male pins. It is mainly used in the electronic industry and provides an easy plug-in/plug-out connection. Its two-piece system is designed with a contact surface that prevents accidental disconnection and also has a metal shell to protect it from electromagnetic interference. Therefore, 78280-430 connectors are the ideal choice for a variety of electronic applications.
