Replaceable Battery Feature

      Disclosed is a method for using a pluggable battery holder as a
battery backup for printed circuit cards to save data and functions
during power failures.

      The Figure shows a battery (1) with a connector (2) attached to
it by means of a snap on device (3) which has wires attached to the
connector (2).  The connector shown is a standard "D" shell,however
any type of connector could be used.

      A molded plastic snap together housing (4) is used to enclose
the battery for protection and for aesthetic reasons.  Both halves of
the snap together housing are identical, saving tooling dollars and
assembly time.  Although a 9 volt battery is shown, the housing can
be designed for any type of battery.  Note that the housing can be
separated for battery replacement.

      To use the pluggable battery holder as a battery backup, a
mating connector is installed on a printed circuit card.  The battery
holder is plugged into the mating connector and retained by means of
two thumbscrews (5).

      If shielding is required for EMC reasons, the battery is
covered with a dielectric material, wrapped with copper foil and the
seams are soldered prior to enclosing the battery with the snap
together housing.
