Backplane Connectors - Hard Metric, Standard

17051332403 Application Field and Working Principle

The 17051332403 backplane connectors are high-speed, high-density connectors designed for computer backplanes, system boards, and chassis applications. They are available in hard metric and standard form factors. This article will discuss the application field and working principle of 17051332403 and their related terms.

Application Field

The 17051332403 backplane connectors are mainly used in computer backplanes, system boards, and chassis applications. The hard metric version can be used in backplanes with up to 16 ports and is capable of passing up to 32A at 500V. The standard version can be used in applications with up to 24 ports at up to 30A. The connectors can also be used for other purposes, such as high-speed data transfers, and are also suitable for signal or power applications.

Working Principle

The 17051332403 backplane connectors primarily follow the “Radial Design” principle. This principle states that connectors should be designed with the contact spring tips installed along a certain radius. This ensures that all of the contacts will be evenly loaded, which improves both reliability and performance. The contact arrangement can also be changed to accommodate different port numbers. Additionally, the contact arrangement can be changed according to the application. The connectors can also be easily replaced in the field, as the entire connector can be removed from the board with a simple twist.

The contacts are designed to be crimp or solder terminated. They are made from gold plated beryllium copper (BeCu) and are pre-loaded onto the PCB by a snap-on mechanism. This is done to ensure that the contacts are firmly secured in place. The contacts can be loaded with up to 32A at 500V, making them ideal for power or signal applications. The connectors also feature low-skew characteristics, which helps improve signal integrity.

The 17051332403 backplane connectors also feature a “Floating Spacer” design. This design ensures that the contacts are firmly held in place, even in vibration-prone environments. The spacer also provides a certain amount of flexibility, which helps to reduce the amount of movement between the contacts and the board. This results in improved signal integrity.

The 17051332403 backplane connectors feature a flange on the housing for easy mounting. Additionally, the housing is also designed to provide EMC shielding to ensure that signals and power are shielded from external sources. This helps to reduce the amount of electromagnetic interference that can be encountered in high-frequency applications.

Conclusion

In conclusion, the 17051332403 backplane connectors are designed for applications with up to 16 or 24 ports and are capable of passing up to 32A at 500V. They feature a radial design that helps ensure contact loading is evenly distributed, as well as a “Floating Spacer” design to ensure contact stability. The housing also provides EMC shielding to ensure signal and power integrity. The connectors can also be easily replaced in the field with a simple twist.
