Abstract

This article describes a method to make it possible to remove the socket end of the IPI or the DFCI cable from a panel installation and abut it to the plug end of another IPI or another DFCI cable. On panel installations, the IPI and DFCI cables require shorter stud lengths on the socket end of the cable to prevent the thumbscrew from bottoming out on the mating stud on the panel. When the cable is removed and abutted to another cable the stud is not long enough and the ends are not positively retained. This method shortens the thumbscrew for panel installation and lengthens the thumbscrew for cable abutment. In Fig.

IPI and DFCI Cable Thumbscrew Spacer

This article describes a method to make it possible to remove the socket end of the IPI or the DFCI cable from a panel installation and abut it to the plug end of another IPI or another DFCI cable. On panel installations, the IPI and DFCI cables require shorter stud lengths on the socket end of the cable to prevent the thumbscrew from bottoming out on the mating stud on the panel. When the cable is removed and abutted to another cable the stud is not long enough and the ends are not positively retained. This method shortens the thumbscrew for panel installation and lengthens the thumbscrew for cable abutment. In Fig. 1, the molded plastic spacer A is installed on the cable by sliding the center slot over the cable B and sliding the spacer along the cable until the flat surface of the spacer rests on top of the connector C and the counter bore in the spacer fits over the cable- retaining collar of the connector. One set of holes on either end of the spacer align with the holes on both ends of the connector. The two female thumbscrews D are inserted through the holes in the ends of the spacer A and the connector C and pushed through the connector until they snap through the internal retaining ring of the connector C.

The two knurled stud nuts E are pressed into the threaded hole of the thumbscrew D to a total length of 52 mm. In Fig. 2, the thumbscrews B are shortened and lengthened (raised and lowered) by rotati...
