Method and Apparatus for Measuring Cable Assembly Flexibility

Method:

    Cable assemblies are routed in manufacturing operations. Routing requires the cable be malleable and easily routed and maneuvered (workable) by operators as they install these in areas with space constraints. This embodiment allows for a determination of cable flexibility within an application.

    There are two parts to this invention. One is a novel process/methodology and the other hardware,
1) Process/Methodology:


Flex the cable assembly on a fixture which ensures a specific bend radius to a specific point/angle. The force is applied perpendicular to the plane of the cable loop and displacing the cable a specified distance/angle
2) Hardware: Fixture will ensure a set loop on the cable assembly and secure the cable so that the displacement force if applied at the radius of the loop. See below Figure.

    Cable assembly is placed in the adjustable fixture. The fixture ensures the loop of the cable is 2X the minimum bend radius of the part. The loop secured in the fixture such that the bend point (moment arm) is exactly 50% of the diameter of the bulk cable. The angle in the fixture is adjusted to 30 degrees measured relative the plane of the loop. The force is then applied perpendicular to the loop until the 30 degree point is reached. The displacement result measured.
