Method for a side-swipe low-profile fan connector

Disclosed is a method for a side-swipe low-profile fan connector. Benefits include improved thermal performance.

Background

              Conventionally, fan height has not been an issue for servers. As less than or equal to 2U (3.5-inch) systems are becoming common, conventional methods of connecting hot-swap fans are limiting design success.

Description

              The disclosed method is a low-profile connector for hot swap fans in a computer system. Components include a surface-mount contact plate, contact fingers, and a contact safety guard (see Figure 1).

              Contact fingers on the side of the fan are mounted to the fan assembly. The signal, and power wires are soldered to the fingers. A PCB board underneath the fan bay housing provides the circuitry to interface the fan power and signals to the rest of the computer system. A contact plate is either surface mounted to the PCB board or through-hole mounted and provides the contacts for the contact fingers to touch as the fan is inserted into the fan bay. A contact safety guard is provided to prevent the user from electrocution when the fan is hot-swapped. As the fan assembly is inserted into the fan bay, guide rails ensure proper alignment of the contact fingers, and the contact fingers slide up the contact plate and onto the contacts that provide wipe and, ultimately, the electrical contact.

Advantages

      The disclosed method provides advantages, including:
