Abstract

A non-conductive, tool-actuated, slam latch is designed for use in conjunction with polymeric covers. The latch is self-locking and is made of a non-conductive material to eliminate electrostatic discharge. In addition, the latch is self-restoring when the cover is closed. The latch is secured to the cover 11 with a flat head screw 12 that bottoms out in the thread seat, thus allowing clearance between the latch and the cover 11 for free rotation. Upon closing the cover 11, the striker plate 13, located on the processor frame, makes contact with the helical surface 14, resulting in latch actuation in a counterclockwise rotation, and applies tension to the strap 15.

Non-Conductive Tool Actuated Slam Latch

A non-conductive, tool-actuated, slam latch is designed for use in conjunction with polymeric covers. The latch is self-locking and is made of a non-conductive material to eliminate electrostatic discharge. In addition, the latch is self- restoring when the cover is closed. The latch is secured to the cover 11 with a flat head screw 12 that bottoms out in the thread seat, thus allowing clearance between the latch and the cover 11 for free rotation. Upon closing the cover 11, the striker plate 13, located on the processor frame, makes contact with the helical surface 14, resulting in latch actuation in a counterclockwise rotation, and applies tension to the strap 15. As the striker plate 13 passes over the edge of the helical surface 14, the strap 15 reverses its rotation, thus locking the striker plate 13 behind the helical surface 14. To unlock, the operator uses an Allen wrench by turning the mechanism clockwise, resulting in the reversal of the above-noted action to take place.
