Abstract

Disclosed is a method that allows the decorative portion or a keylock mechanism to be mounted to the front bezel while the switch is mounted to the computer frame. This enhances the appearance since the keylock mechanism does not have to locate through an oversized hole, but mount directly to the bezel via a tight hole. Since there is no straight conductive path between the mechanical and electrical portions of the keylock, then problems with electrostatic discharge have been eliminat- ed.

Docking Keylock/Switch for Computers

      Disclosed is a method that allows the decorative portion or a
keylock mechanism to be mounted to the front bezel while the switch
is mounted to the computer frame.  This enhances the appearance since
the keylock mechanism does not have to locate through an oversized
hole, but mount directly to the bezel via a tight hole.  Since there
is no straight conductive path between the mechanical and electrical
portions of the keylock, then problems with electrostatic discharge
have been eliminat- ed.

      The docking keylock is accomplished by mounting the lock (1) to
the bezel (2) and the three-position rotary switch (5) to the frame
(4).  A plastic interposer (3) is mounted to the threaded portion of
the lock. The interposer has a keyed hole which mates with the stem
of the rotary switch, but allows front to rear movement.  This is
required since the frame slides to the rear for access.

      Since the frame is removed for service, it is also made secure
by an extension on the interposer (3) that protrudes thru a slot (10)
in the frame.  When the keylock is in the lock or secure position,
the interposer extension is trapped by the narrowed portion of the
slot.

      Another advantage of the interposer allowing front to rear
movement is that it is not tolerance sensitive, allowing for varying
slot (10) shown in frame (4).  Frame (4) is configured for three
positions.  The first allows access to the machine electr...
