Abstract: A birdcage-shaped harness assembly adaptable for electrically connecting a bulkhead support structure with a rotatable gimbal support structure. In order to avoid excessive torsional forces from acting on the harness, a plurality of conductor portions are bundled together and pre-compressed in length between the support structures. When assembled, the conductor portions of the harness assembly form a birdcage-shaped dynamic bundle wherein the middle of the conductor portions bow away from conductor portions on the opposite side of the bundle. This pre-compression creates a birdcage-shaped configuration that allows the bundle to bend as the conductor portions straighten. This occurs when the gimbal rotates relative to the bulkhead. The bending motion creates relatively little damage to the conductor strands as compared the excessive torsion forces affecting conventional loop-shaped wire harness assemblies.
