CENTRAL VACUUM SYSTEM MOUNTING FLANGE AND HOSE CUFF FOR USE WITH STANDARD ELECTRICAL OUTLETS

摘要

A mounting plate having an orienting portion facilitates orienting the vacuum
connection opening of the mounting plate with respect to an anticipated
orientation of a
receptacle and electrical box. The orienting portion is optionally releasably
attachable to
the main body of the mounting plate which main body comprises the vacuum
connection
opening. The mounting plate is mounted prior to installation of the electrical
receptacle in
the electrical box. The orienting portion of the mounting plate facilitates
orienting the
vacuum connection opening in a known orientation with respect to an
anticipated
orientation of the electrical receptacle when inserted in the electrical box.
After
installation of the inlet valve and the electrical receptacle, a hose cuff
having standard
electrical terminals oriented with respect to the vacuum connection of the
hose cuff may be
simultaneously inserted into the electrical receptacle and the vacuum
connection opening.
The electrical terminals in the hose cuff are oriented with respect to the
vacuum connection
in a second known orientation corresponding to the first known orientation
such that the
electrical terminals mate with the electrical receptacle which has been
installed in the
electrical box when the vacuum connection opening receives the vacuum
connection. In
this manner, a hose cuff utilizing standard electrical terminals may be mated
with an
electrical terminal without interfering with the electrical box. Furthermore,
because the
orienting portion is releasably attached to the main body, the orienting
portion can be
removed to avoid interference with other trades.
