A feedthrough coaxial cable connector includes a tubular mandrel body dimensioned to be pressed between a foil-bonded dielectric core and other elements of an outer conductor of the prepared end of the cable. The body has cable engagement surface which defines a knife edge projection therearound for engaging an outer conductor of the cable by creating shear stresses therein without actually shearing the outer conductor. A tubular shank portion extends from the cable engagement surface portion to a radial wall portion, and a jack engagement portion is coaxial about the exposed central conductor. The jack engagement portion achieves a tight friction fit upon a jack and may be formed as an inside compression collet. A radial compression providing structure causes an inside surface region of the outer conductor to bear directly against and bend over the knife edge portion. Preferably, a slideable shell is slideably positionable generally away from a connector end facing the outer surface of the jack to enable the jack engagement portion of the connector to slide over the outer surface of the jack, and slideably positionable toward the connector end so as to radially compress the radially diverging jack engagement portion against the outer surface of the jack to secure the connector thereto. A kit of parts including an expendable installation tool enables proper assembly of the cable connector without special skills or tools.

Feed through coaxial cable connector

Articles including a thin laminar heating element composed of a sintered conductive polymer, and electrodes attached to the heating element so that current flows in the plane of the element. The article can be placed between and in contact with two substrates, and then heated to join the two substrates together. Preferably at least one of the substrates is polymeric and becomes melt-fused to the article.
