Press nut designs to minimize stack thickness

Abstract:

The described embodiments relate to embedding a threaded insert into a thin-walled housing. A recess can be formed with a machining tool that forms a recess in a thickened portion of the thin-walled housing. In some embodiments, the recess can be formed along one of the walls of the thin-walled housing in a location having highly a constrained amount of space available. Once the recess is formed a threaded insert can be pressed into the recess. An interference fit can be utilized to lodge the press-nut securely within the recess. Alternatively, a retaining member can be positioned across a front portion of the recess to trap the threaded insert between the retaining member and a rear surface of the recess.
