Introduction

Backplane connectors are devices used to link printed circuit boards or other mechanical components together, form a circuit path which can carry electrical signals from one board to another. Housings are products used to protect the contacts within the backplane connectors, providing support, strain relief and grounding. Model 516-056-000-351 backplane connector housing is one of the many products made to achieve such purpose. This article will discuss the application fields and the working principle of this type of housing.

Application Fields

Model 516-056-000-351 backplane connector housing is used for general purpose applications that have press fit contacts, such as boards and wires. It is suitable for applications that require low temperatures, higher shock and vibration ratings, and electro-magnetic interference (EMI) shielding. Because of its compatibility with a wide range of materials, it is widely used in industrial and medical applications.The applications involving Model 516-056-000-351 backplane connector housing can also be used in the telecommunications industry due to its low contact resistance rating, reliable signal transmission, and highly stable performance. Its usually used in setups requiring a high number of connections such as in public switching networks and access networks.In addition, Model 516-056-000-351 backplane connector housing is commonly utilized in the aerospace and defense industry, as it is able to withstand high temperatures and extreme conditions while still providing consistent and reliable results. These housings can endure harsh environmental conditions such as exposure to sand, rain, humidity, and extreme temperatures without degrading in performance.

Working Principle

Model 516-056-000-351 backplane connector housing is a two-piece connector designed to deliver reliable performance even in the presence of extreme conditions. The housing is made from brass and offers a secure and reliable means of signal transmission. The housing consists of two parts: a base and a cover, which provide strain relief and shielding for the pins/contacts within the backplane.The base and the cover are held by an insert that provides the electrical and mechanical connection. The housing is designed to ensure proper mating of the pin contacts and to provide a secure mechanical connection between the board and the housing. This results in high reliability and low insertion and extraction forces, which eliminates the need of extra mechanical components such as tools or screws.The contact area is designed to ensure reliable electrical performance in the presence of extreme conditions such as high electromagnetic interference (EMI) fields and high vibration. The contact area is designed with an open slot, allowing for a free contact of the pins, while still ensuring that the pins are properly secured. The housing also provides mounting pins to hang the housing from the board.

Conclusion

Model 516-056-000-351 backplane connector housing is designed for use in general-purpose applications with press fit contacts, and its suitable for applications requiring high reliability and low contact resistance rating. It offers reliable electrical performance in harsh environmental conditions, such as exposure to radiation, temperature variations, humidity, and shock, vibration, sand, and rain. The housing is composed of two parts, a base and a cover, that provide strain relief and shielding for the pins/contacts within the backplane. The contact area of the housing is designed with an open slot to ensure reliable electrical performance and the mounting pins provide a secure connection between the board and the housing.
