Abstract

Customer setup (CSU) systems that have external cables with "D"-style connectors A must have CSU thumbscrews. Using push-in, pull-out thumbscrews B with molded plugs C easily allows a person to change thumbscrews without the use of tools. Some computer systems use customer-pluggable, external "D"-type cables with thumbscrews to retain the cable in its mating connector (Fig. 1). Sometimes, this thumbscrew must be changed due to damaged threads or because a different thread size is wanted. Using the push-in, pull-out CSU thumbscrew B, and molded plugs C, a person can change by simply pulling out the old thumbscrew and pushing in the replacement thumbscrew. As shown in Fig. 2, thumbscrew B has a groove 10, a boss 12 and a relatively small diameter screw threaded end 14.
