INTERLOCKING FRAME AND SLIDE-ON COVER FOR ELECTRONICS ENCLOSURE

FOR ELECTRONICS ENCLOSURE

        � � � � � A method and apparatus, according to the principles of the invention, creates an electrical contact for EMI suppression of an electronics enclosure by retaining the front edge of a slide‑on cover.

        � � � � � The cover is placed onto the frame (see Figures 1 and 2) from the top or rear of the unit (see Figures 3 and 4).� As the cover is slid forward to the final assembly position, the front flange of the cover slides beneath hooks/catches stamped into the front flange of the frame (see Figures 5 and 6), creating pressure between the cover and the frame.� The cover is also trapped and is not free to move.� Bumps may be added to either part to create the electrical contact points for the EMI enclosure.
