Abstract

Disclosed is an assembly for determining if the cover of a computer system is installed or removed and for determining if the system is in a fully locked, secure condition or in an unlocked condition. The assembly includes a molded plastic carrier, a first switch operated by the rotation of a keylock, and a second switch operated by the installation or removal of the cover.

Electromechanical Security Assembly

      Disclosed is an assembly for determining if the cover of a
computer system is installed or removed and for determining if the
system is in a fully locked, secure condition or in an unlocked
condition.  The assembly includes a molded plastic carrier, a first
switch operated by the rotation of a keylock, and a second switch
operated by the installation or removal of the cover.

      The Figure is an isometric view of the security assembly, as
viewed from above and behind.  A first switch 10 and a second switch
12 are held in place by pins 14, which are integral portions of a
molded plastic carrier 16.  Each pin 14 has an interference rib which
is deformed as the associated switch 10 or 12 is pressed into place.
This kind of deformation assures that sufficient pressure is
developed to hold the switch in place.  Carrier 16 also includes a
number of locating features 18, which allow the security assembly to
be snapped into place within a chassis of the computing system.

      A cam 20 rotates in the directions of arrow 22 with a keylock
assembly (not shown), which provides a security function, such as
locking the cover in place on the computing system.  The rotation of
the keylock and cam 20 in either direction between a locked, secure
position and an unlocked position operates the first switch 10.

      The cover assembly of the computing system includes a front
cover 24 having an inward-extending pin 26.  As the cover assembly is
moved into place on the computing system in the rearward direction of
arrow 28,...
