50295-5128H

Backplane connectors are specialized electrical connectors designed to be large and reliable enough to be used in backplanes and other challenging electrical connection applications. The 50295-5128H is an example of a backplane connector designed to meet the rigorous MIL-STD-1760E specification.

Application Field

Backplane connectors, such as the 50295-5128H, are usually used in high-speed connection applications, such as in computers, telecom systems and avionics. They are designed to meet the strict requirements for low insertion force (LIF), high-density packaging and reliability. The 50295-5128H, for example, is designed to meet the MIL-STD-1760E specification, which requires that the connector be able to support high-speed signal transmission, be shock- and vibration-resistant, and be electronically and thermally compatible with the systems they will be used in.

Working Principle

Backplane connectors such as the 50295-5128H are designed to provide reliable signal transmission between devices. To meet this requirement, the connectors are designed to make electrical contact with the mating interface while maintaining integrity throughout the connection. This is done by using a contact system that includes a ferrule, contact pins or contacts, and shell.

The 50295-5128H, for example, uses a two-piece contact system consisting of contact pins and a ferrule. The contact pins are inserted into plated holes in a printed circuit board (PCB). Then, the ferrule is crimped over the contact pins to ensure reliable electrical contact. The ferrule is made of metal, usually copper alloy, for electrical conductivity and durability. Finally, a plastic shell is placed over the ferrule to protect the contact system from environmental elements, such as moisture, dust, and debris.

Conclusion

The 50295-5128H is an example of a backplane connector designed to meet the MIL-STD-1760E specification. It is used in high-speed connection applications, such as in computers, telecom systems and avionics. The connector works by making electrical contact with the mating interface while maintaining integrity throughout the connection, using a two-piece contact system consisting of contact pins and a ferrule. A plastic shell is then placed over the contact system to protect it from environmental elements.
