ABSTRACT:
Interlock means are described for protecting against the surreptitious entry into, and tampering with security type communication systems. A connector interlock plate is provided which prevents the removal of an access cover on the electronic device cabinet without the first removal of a standard cable connector assembly. Concurrently, removal of the cable assembly actuates an electrical switch which destroys the confidential information being stored and processed within the device.
