Bussbar Interconnection System (Captive)

      Disclosed is a mechanical device which prevents the undetection
of cross threaded hardware in bussbar to bussbar or bussbar to
component connections.

      Fig. 1 illustrates the exploded hardware consisting of a
polycarbonate housing, bellville stack, ferrule, red polycarbonate
indicator flat and spring.  During assembly of this captive hardware,
the indicator flag is snapped around the ferrule, then slipped under
the ferrule lip.  The bellville stack is placed within the ferrule
and the bolt is inserted through the bellville stack and ferrule.
The assembly is then placed into the housing which is followed by the
spring.  The spring is retained in the housing via retractable tabs
which are molded into the housing (retractable tabs are not shown).
The captive hardware assembly is then snapped into a retaining ring
which is attached to the bussbar (retaining ring not shown).

      Fig. 2 illustrates the disengaged hardware assembly mounted to
a bussbar.  Note the indicator flag protruding through the slot in
the housing.  This provides visual orientation of the bolt.

      Fig. 3 illustrates engagement of the captive hardware.  During
engagement, the bolt is threaded into a captive nut (captive nut not
shown) which is attached to the mating bussbar or component.  During
this operation the captive hardware is drawn towards the bussbar,
including the indicator flag, which is being drawn by the ferrule.
