Abstract:

A locking security arrangement is provided for both mounting an electronic component on and locking the component to a bracket assembly. A threaded shaft removably mounted on a tumbler of a lock assesmbly by threaded engagement in an aperture is inserted through a non-circular aperture in the bracket assembly. The shaft is advanced into a threaded aperture in a housing of the electronic component until a non-circular portion of a housing of the lock assembly approaches and then enters the non-circular aperture. A key inserted in the tumbler permits continued rotation of the threaded shaft through rotation of the tumbler relative to the lock assembly housing in response to turning movement of key, to continue advancing the threaded shaft into the threaded aperture in the housing of the electronic component until the non-circular portion of the housing of the lock assembly is completely seated within the non-circular aperture. With the key then removed from the tumbler, unauthorized removal of the electronic component is prevented. However, authorized removal of the component is accomplished by inserting the key in the tumbler and rotating the tumbler in a direction to withdraw the threaded shaft from the threaded aperture in the component housing.
