Housing Insert for Connector Keying

      Disclosed is the use of a flexible insert, pressed into an
aperture in a housing covering a port connector, to provide a keying
surface mating with a keying feature of cable connector to ensure
that an attached cable is installed correctly.

      As shown in the Figure, a housing 1 of a peripheral unit 2,
which may be, for example a liquid crystal display, includes a
housing aperture 3 over a port connector 4.  Various electrical
signals are provided to unit 2 by means of a cable 5 from another
unit.  Cable 5 is connected to unit 2 by means of a cable connector
6, which includes a keying feature 7 on one side to prevent the cable
from being installed incorrectly, as in a displaced or inverted
orientation.

      A flexible steel insert 8 is installed within housing aperture
3 to mate with keying feature 7 as cable connector 6 is inserted
through an aperture 9 within insert 8 to mate with port connector 4 .
This aperture 9 includes a keying surface 10 mating with keying
feature 7.  Insert 8 is an integral stamped and formed part including
a pair of centrally extending strap sections 11, joined at each end
by an end section 12.  Each end section 12 includes a pair of lanced
and formed barbs 13.  Strap sections 11 are formed into a convex
shape, projecting outward centrally.

      When insert 8 is installed in aperture 3, central pressure is
applied to strap sections 12, so that these sections flatten or
deflect...
