Resilient Cover Magnet Ground Plate

Ground plate 8 is resilient and thus provides a reliable electrical ground path between machine frame 5 and its cover 6.

Magnetic latch A magnetically latches cover 6 with respect to machine frame 5 and for this purpose includes a stacked series of metal plates 2 and magnets 3 secured to baseplate 4 by rivet 1. Plate 8 has two screw holes 8A, and baseplate 4 has corresponding holes for two screws (not shown) to secure plate 8 and baseplate 4 to machine frame 5. Rivet 1 loosely extends through metal plates 2 and magnets 3 so as to permit metal plates 2 and magnets 3 to move in and out, as well as pivot about rivet 1. Bracket 11 is fixed on cover 6 and contacts the ends of plates 2 when cover 6 is closed on frame 5 and latch A is effective.

Plate 8 is a magnetic material such a stainless or carbon steel, and its surface 9 is magnetically attracted to plates 2. Plate 8 has two narrow spring arms 10 that cause surface 9 to maintain constant contact with plates 2, assuring a continuous ground path from cover 6 through bracket 11 and latch A to machine frame 5.
