Contact Retention Test Machine and Hood Assembly
This machine is fully automatic in its operation with mechanical cam operated functions. The machine is designed and built to automatically load test the contact spring tines for max. and mm. retention force through dead weight. The contacts of various sizes are vibratory bowl fed into a mechanical escapement head into the contact nest on the cam operated index table. All of the components handling the contacts are quickly interchangeable. They are fitted so that no adjustments are required for the various contact sizes, escapement, nests, pin length stops and the test pins with weights. The top plate indexes and the bottom plate is cammed up and down and holds the test pins and the max. and mm. weights. The machine is programmed to eject the contacts within tolerance into their container and the contacts that are above and below tolerances into their respective reject containers.
