ABSTRACT:
The present invention presents an improved clip and an improved block wherein the material requirements for the clip are reduced and transmission performance for the assembly is improved. The present invention also presents a method of manufacturing the improved clip. The clips are of the type generally referred to in the art as 66 type clips. The clip of this invention has an oval opening with parallel sides between the base and that portion of the clip which holds the wire; and the oval aperture is flanked by arm portions of diverging width from the top of the aperture to the bottom of the aperture. In other words, the sides of the arms adjacent to the aperture are parallel, and the sides of the arms remote from the aperture diverge outwardly. This makes the arms thicker in width as they approach and join the base. This construction achieves the important advantage of a tapered beam element, which is well known to result in superior stress distribution than beams whose thickness is uniform. The design of the tapered arm portions of the present invention thereby produces equal or slightly higher normal forces than the prior art 66 clips with approximately 25 percent less material. Also, when displaced by a terminated wire, the clip of the present invention provides higher normal force than the prior art clip described in U.S. Pat. No. 5,127,845, which has greater material content.
