Abstract

Disclosed is a method for a new sheet metal hinge joint that prevents the loss of internal air pressure when components (e.g. power supplies, fans, server blades) are removed from the server. Benefits include a solution that requires no additional parts and is easy to assemble.

Low-Cost, Low-Profile Sheet Metal Hinge Joint

Disclosed is a method for a new sheet metal hinge joint that prevents the loss of internal air pressure when components (e.g. power supplies, fans, server blades) are removed from the server. Benefits include a solution that requires no additional parts and is easy to assemble.

Background

Current implementations consist of a ridged body, a moving body, and a pivot pin. The pivot pin, and the sheet-metal geometry required to support the pivot pin, increase manufacturing costs and take up valuable space. In addition, the pivot pin can be difficult to install and retain.

General Description

The disclosed method consists of a ridged body and a moving body. The ridged body contains a T-slot and retention slot cut outs that accept a pivot element and a retention element on the moving body (see Figures 1 and 2). When the ridged body and the moving body are held perpendicular to each other, the pivot element is inserted into the T-slot on the ridged body. The moving body is then moved back until the retention element is allowed to enter the retention slot. The moving body is then rotated toward the ridged body. 

This sub-assembly is placed into a larger assembly that constrains the motion of the moving body, so that the angle of the moving body to the ridged body does not exceed 60o.  The moving body freely rotates from 0o to 60o with the retention element preventing the parts from
falling apart.
