Abstract
Abstract A strain relief component for applying strain relieving forces to a multi-conductor flat cable at a location remote from that at which the individual ones of the cable conductors are connected to the electrical contacts of a termination connector, the strain relieving forces being applied with resilient members carried on cover parts fixedly connected to the termination connector.

Claim 1
Independent Claim
309 words
For use with an electrical connector of the type receptive of flat cable having a plurality of conductors, said connector including an elongated insulator body having a plurality of conductor receptive channels and a plurality of electrical contacts carried one each in the respective ones of said channels for electrically connecting an associated one of the cable conductors therewith, a cable strain relief component fittable to said connector and comprising a pair of cover parts each having an elongated panel segment and embodying means for fixedly securing said panel segments to said insulator body at opposite sides of such body, said securing means holding said cover parts panel segments in disposition overlaying said channels and spaced therefrom; resilient members carried on each of the respective cover parts and when said panel segments are fixedly secured to said insulator body extending into resiliently yieldable engagement with said cable on opposite side faces thereof at a location remote from said contacts and thereby applying at such remote location oppositely directed strain-relieving bias forces to the cable, and resilient members being substantially elongatedly coextensive with said panel segments and extending laterally relatively of said panel segments from a location of adjacency therewith in courses of convergence with and having termini at the opposite faces of said cable at said remote location; cover part side skirts carried at opposite ends of the panel segments, the skirts of one part being alignable with those of the other part to define cover side walls othogonal to said panel segments, said side skirts of each cover part being fixed to the opposite ends of its panel segment and further extend alongside the respective opposite ends of the associated resilient member but spaced a distance therefrom; and complementary engageable latch means carried on the cover parts for latching such parts together to define a unitary enclosure structure.
