One-Screw Assembly of Power Supply Enclosures

      Disclosed is a design for cost reduced assembly and disassembly
of power supplies, using the bare minimum quantity of mounting screws
of ONE.

      This disclosure describes an innovative method to join chassis
and covers.  It allows to couple two enclosure parts using ONE SCREW
only.  This results in a fast and reliable assembly and disassembly
process, while simultaneously all technical requirements are
fulfilled.

      Flanges on chassis and brackets on covers guaranty - together
with the one screw - a closely sealed power supply (Fig. 1).  The
cover slides onto the tabs of the chassis and is finally secured by a
single screw.  Sufficient sealing is achieved by the overlapping of
tabs and brackets.

Benefits of this innovative design are:
  o  ONE tread only to the chassis
  o  ONE hole only to the cover - which both safe parts manufacturing
      cost
  o  ONE screw only required - which is the minimum needed for safety
      reasons.
  o  ONE mounting direction only - which allows assembly automation
or
      use of robotics.

      Cost savings can be realized with this design during parts base
cost, mounting, maintenance and disassembly.

Figs. 2a and 2b show details of alternative bracket designs at the
cover.
