Backplane connectors are used for connecting to a backplane in an electronic system. They are designed to facilitate the flow of information between devices such as computers, routers, and switches. The 51940-078 backplane connector falls into the specialized class of connectors and has its own unique characteristics with respect to application field and working principle.

The Application Field of the 51940-078 Backplane Connector

The 51940-078 backplane connector is optimally used for high-speed data transmission in backplane applications where large numbers of I/O connections are necessary. It is designed to achieve high speeds and provides high noise immunity for reliable signal integrity. Its extreme vibration and shock resistance make it an ideal choice for automotive and aerospace applications. The asymmetrical design of this backplane connector eliminates any crosstalk concerns and offers the highest possible performance.

The connector is suitable for excess temperature environments (up to 105C). The unique designed contact system allows increased current rating and also prevents any risk of system overheating, making it an optimal choice for power applications. The dust shutter is designed in such a way that it protects the contact cavity while also having good accessibility. These features make it suitable for power, hybrid and intelligent applications. 

Working Principle of the 51940-078 Backplane Connector

The 51940-078 backplane connector is based on a push-pull mating method. It features two rigid plastic connectors which are inserted into a counter contact holder. An adjustable latch locks into the counter contact holder adopting a latching performance and a wire retention screw secures the contacts. The contact alignment happens in a 3-point-position in a way to ensure that the L-C contacts remain secure when the connector is mated.

The contact-retention clip is designed to securely hold the contacts in the connector housing while providing a stable connection between the contacts and the backplane. It also ensures a low-resistance connection between the two and eliminates any risks of contact corrosion. The high-quality insulation within the connector keeps the electrical signals separate from each other and ensures an efficient transmission of electricity from one device to another.

The gold plated contact area enhances the performance of the connector and ensures a reliable transmission of signals between contacts. This gold layer also offers excellent electrical conductance which results in better signal transmission and accuracy.

Conclusion

The 51940-078 backplane connector, with its unique application field and working principle, is an ideal choice for high-speed data transmission in backplane applications. Its dust shutter, adjustable latch, and contact-retention clip make it suitable for a wide range of applications such as automotive, aerospace and power applications. The gold plating of contact area provides an efficient and reliable transmission of electricity from one device to another. All of these features of the 51940-078 backplane connector make it an optimal choice for backplane applications.
