摘要： An automatic cable assembly testing apparatus and procedure. The connectors at each end of a cable assembly are isolated from the cable and from a test source. Each connector is then injected with a plurality of test frequencies and the leakage currents sensed for each of these tests. The leakage current for a particular test is compared against a corresponding reference level and pass/fail lamps are used to provide a visual indication of the test results. The sequence of tests for each end of a cable assembly over a range of frequencies can either be accomplished either automatically or manually. The preferred embodiment illustrates a microprocessor based controller for operating the system.

摘要： A flexible shielded cable. The cable includes an elongate flexible metal conductor and a layer of a flexible dielectric material disposed about the conductor. The cable has a flexible metallic shield positioned about the dielectric with the shield including a copper foil having overlapping edges and a copper braid about the foil. A layer of metal bonds together the overlapping edges, bonds the braid and the foil and closes the openings of the braid. A method of forming a metallic shield is also disclosed.

摘要： A radiating air-dielectric coaxial cable for plenum applications comprises an inner conductor; a non-halogenated dielectric spacer around the inner conductor; and a single, continuous, outer conductor surrounding the dielectric spacer in direct contact therewith. The outer conductor has apertures along its length for the passage of electromagnetic radiation. At least one layer of inert, flame-retardant barrier tape is wrapped over the outer surface of the outer conductor so as to cover each of the radiating apertures of said outer conductor to prevent the dielectric spacer from flowing out through the radiating apertures when the dielectric material is melted. A jacket of halogenated, highly flame-retardant polymer is extruded over the wrapped layer of barrier tape.
