ABSTRACT:
In order to provide a secure housing assembly for an electronic lock, while also providing protection against electrostatic discharge, a conductive plate-based housing assembly is configured to be installed within either a door mortise, or as an escutcheon housing mountable to the exterior of the door. For either installation, the same metallic plate sub-assembly is employed as both a support structure for a circuit board of the lock's electronic circuitry and as a wall of the protective housing. Since the circuit board's ground conductor layer is electrically connected to the metallic plate via conductive mounting standoffs, the lock circuitry is protected against damage due to electrostatic discharge when a key is inserted into a keyway of the lock.
