Apparatus for mounting electronic circuits in electric power equipment enclosures

1. Field of the Invention A pair of circuit boards, or electrically insulative panel members on which the circuit boards are mounted, have side edges which slide into aligned longitudinally extending slots in a pair of facing, spaced apart cantilevered free sections of a pair of planar legs of a bracket secured to a panel in an electric power equipment enclosure. A terminal portion of one free section diverges outward to form a camming surface against which a complimentary camming surface on a rearward edge of a tab on the associated side edge of the panel member bears to spread the free section apart until the tab passes into the slot and the terminal portion snaps over the tab and engages a latching surface on the forward edge of the tab to latch the panel member to the bracket. The panel member is released by lifting the diverging terminal portion of the one free section to clear the latching surface and sliding the panel member out of the slots.
