Abstract: A inner jacket member 1 having slit elements 1a is inserted into an outer jacket member 2. An inner jacket member pressing portion, 4, 13 for closing or dilating the inner jacket member 1 is formed within said outer jacket member 2 in such a manner as to be opposite the front end portions 1b of the split elements 1 a. A male terminal 7, 8 to be contacted with an electric part, such as the leadless IC or the like, under pressure is disposed at a tail end of either of the outer and inner jacket members 2 and 1.

Abstract: In a flat cable connecting system comprising pinching a multiple core flat cable between a connector cover and a connector substrate having contacts to cause the contacts to pierce through an insulator of the multiple core flat cable and, in conjunction therewith, to catch hold of and electrically connect conductors within the insulator of the multiple core flat cable, the improvement comprises forming in the insulator perforations for dividing the conductors into conductor segments extending in one direction and conductor segments extending in the other direction, and causing different signal contacts of the connector substrate to catch hold of and electrically connect the respective conductor segments at their terminals on the perforation sides, thereby forming different signal lines with the perforations as boundaries.
