Electrically coupling an avionics line replaceable unit with an avionics test station
First Claim
1. A system of a type having an avionics rack, on an aircraft, for containing a plurality of avionics line replaceable units, and furtherhaving a first rack/line replaceable unit connector, said plurality of avionics line replaceable units comprising a first avionics replaceable unit, coupled to said avionics rack, the improvement comprising:
- a test unit adapter having a second rack/line replaceable unit connector, a test unit adapter/test station connector, and a rigid electrical connection between two printed circuit boards, disposed therebetween;
said test unit adapter is disposed outside of said aircraft;
a second avionics line replaceable unit, having an avionics line replaceable unit rear blind mating connector thereon, which has a predetermined configuration so as to be readily mated with said first rack/line replaceable unit connector, said predetermined configuration further configured so as to be readily mated to said second rack/line replaceable unit connector; and
, a test station coupled to said test unit adapter, said test station for testing said second avionics line replaceable unit.

Abstract
An avionics test unit adapter for interfacing between an avionics test station and an avionics line replaceable unit, where the test unit adapter is blind mated with both. The test unit adapter has therein at least two rigid circuit cards used for signal distribution or transmission. The two rigid circuit cards being rigidly coupled to each other through an edge connector while each circuit card is mounted within the test unit adapter with the ability to float therein in at least three orthogonal directions.
