Abstract: For the purposes of connecting and joining conductive traces on printed circuit boards, the stripped ends of a flexible multi-conductor flat cable are inserted into metallized openings in the printed circuit boards. The cables are cut to length and their ends are stripped of insulation and supported in an injection molded bar member. Those ends are desirably not to be bent in storage and transportation.
