Abstract: A family of retainer clip holders can each be adjusted to properly position a retainer clip at a desired location on a wire harness. In the past, it has sometimes been complicated to properly position a retainer clip holder relative to the base, and mount the holder base on a jig for assembling wire harnesses. There have typically been too many fixtures required on the jig. Thus, the prior art has attempted to assemble the retainer clips by individually tailoring hundreds of retainer clip holders for the particular orientation demanded by the particular retainer clip application. The inventive family of retainer clip holders allows the selection of the proper adjustable retainer clip holders and the adjustment of that retainer clip holder to accommodate the particular retainer clip application demanded. In this way, the invention replaces the hundreds of previously required holders with seven basic tools.

A support is connected to the first end of the swing arm and has an axis spaced from and substantially parallel to the axis of rotation. The support cooperates with the swing arm to permit the swing arm to pivot toward and away from the stator. A detent finger, located in the swing arm cooperates with the stator to hold the stator against rotation when the swing arm is in a predetermined angular position, and maintains the stator in a fixed position relative to the swing arm during a centrifuge operation. Finally, a detent cam assembly resists pivotal movement of the swing arm when the swing arm is in the predetermined angular position.
