Blind Alignment Method for Component Installation

      Disclosed is a blind alignment method for easily and accurately
installing components or subassemblies into a machine chassis.  The
components automatically make electrical connections as they are
installed.  Assembly and service are simplified and adjustments are
eliminated.

      Components such as power supplies and card cages may be
installed into a mating machine chassis using the blind alignment
method.

      The machine chassis 10 (Fig. 1) has a fixed internal bulkhead
11 with two alignment pins for each component.  One pin is the
primary alignment pin 12 and the other is the secondary alignment pin
13.  Each component 14 (Fig. 2) has a mating hole 15 for the primary
alignment pin and a slot 16 for the secondary alignment pin.

      The diameter, vertical position and horizontal position of the
primary alignment pin are tightly controlled with tolerances.  The
diameter, vertical position and horizontal position of the mating
hole in the component are toleranced in a similar manner.

      Only the diameter and vertical position of the secondary
alignment pin are tightly controlled.  The diameter and vertical
position of the mating slot in the component are also controlled
similarly.

      As the components are slid into the machine chassis, the
alignment pins enter the mating hole and slot in the component.  This
locates and aligns the component with the machine chassis.  As t...
