1658043-3 Application Field and Working Principle

Rectangular connectors are widely used in a variety of industries, most prominently in the automotive, industrial, consumer and medical sectors. The 1658043-3 rectangular connector is a type of edge connector designed specifically for microcomputers and other embedded systems. It is designed to provide a reliable and secure connection between a motherboard and daughtercard. This article will discuss the application field and working principle of the 1658043-3 rectangular connector.

Application Field

The 1658043-3 is designed for use in edge connection applications. It is particularly well-suited for applications such as mezzanine boards, memory modules, and small circuit boards. It features high-reliability and improved performance compared to pin-to-pin connectors, which is beneficial in applications with heavy usage and long life cycles. It is also ideal for applications that require thermal or power dissipation, as the connector’s overall surface area is larger than a pin-to-pin connector.The 1658043-3 is often selected for applications that require a high degree of versatility and reliability, such as in telecommunications equipment, microcomputers, embedded systems, and industrial control boards. Its compact design makes it suitable for use in confined spaces, while its resistance to corrosion and other environmental factors ensures its durability and long life.

Working Principle

The 1658043-3 is designed to provide a secure connection between a motherboard and a daughtercard. It consists of an array of metal terminal pins, which are inserted into the edge connector’s receptacle. The connector\'s receptacle is then secured to the bottom of the daughtercard with screws. The daughtercard is then connected to the board via the male counterparts of the terminal pins.Electrical signals pass between the device and the daughtercard via the terminal pins, which provide a secure connection. The 1658043-3 connector features a gold plating that enhances its overall conductivity, and a key line that keeps the connector correctly inserted into its mating receptacle. The connector also features two isolators to prevent short circuits between the mating boards.

Conclusion

The 1658043-3 rectangular connector is a reliable and high-performance edge connector designed for microcomputer and embedded system applications. It offers increased versatility, strength, and resistance to corrosion and environmental factors. Its ability to provide secure and reliable connection between a motherboard and daughtercard makes it ideal for a number of industries and applications.
