Backplane connectors are a family of specialized connectors designed to facilitate the connection of electronic devices in electronic systems. The MMH25-029 is an example of such a connector. This article discusses the application field and working principle of the MMH25-029.

Application Field of the MMH25-029

The MMH25-029 is a backplane connector designed for use in the telecommunications industry. It is particularly useful for applications requiring high quadrant connection density and superior performance when harsh environmental conditions are present. It is suitable for use in cellular base stations, telecommunications equipment, and other industrial applications. The connector is also RoHS (restriction of hazardous substances) compliant, making it a good choice for users seeking to adhere to environmental requirements.

Working Principle of the MMH25-029

The MMH25-029 is an 84-position backplane connector. It features four quadrants with 24 positions per quadrant. Each quadrant is made up of 3 x 8 pin configurations and offers both center-to-center and side-to-side mating options. The connector is designed to ensure reliable transmission of high-frequency electrical signals and power up to 200 Amps.

The connector includes two sets of dielectric columns, also known as insulator columns. These columns form the interface between the mating elements and the connector body. The dielectric columns provide support for the contacts and ensure quality insulation between the contacts and the housing. The columns also ensure proper alignment between the housings when mated.

The design of the MMH25-029 includes a variety of features to ensure reliable performance. These include a durable, stainless steel springs designed to provide corrosion resistance and reliable electrical contact. The stainless steel spring arms act as spring loaded contacts that maintain contact force and provide secure contact retention even in harsh environmental conditions. The MMH25-029 also features a thermoplastic contact holder that is designed to provide superior EMC performance.

Conclusion

The MMH25-029 is a specialized, 84-position backplane connector designed for use in the telecommunications industry. It is suitable for applications requiring high quadrant connection density and superior performance in harsh environmental conditions. The connector features two sets of dielectric columns, stainless steel springs, and a thermoplastic contact holder to ensure reliable performance. It is also RoHS compliant, making it a good choice for users seeking to adhere to environmental requirements.
