摘要： A method of making a flexible coaxial cable is provided. The method comprises advancing a cable core comprising a conductor and an expanded foam dielectric surrounding the conductor along a predetermined path of travel, directing an elongate strip of copper onto the advancing cable core and bending the copper strip into a generally cylindrical form so as to loosely encircle the core. Opposing longitudinal edges of the thus formed copper strip are then moved into abutting relation and a longitudinal weld is formed joining the abutting edges to thereby form an electrically and mechanically continuous tubular copper sheath loosely surrounding the cable core. The cable core and the surrounding sheath are simultaneously advanced while the tubular sheath is deformed into an oval configuration loosely surrounding the core. The longitudinal weld of the advancing sheath is then directed against a scarfing blade and weld flash from the sheath is scarfed from the sheath. The advancing copper sheath is sunk onto the advancing cable core to form the coaxial cable. A polymer composition may be extruded around the copper sheath to form a protective jacket surrounding the coaxial cable and may be bonded thereto. The present invention also includes a flexible coaxial cable having excellent electrical and bending properties.

摘要： PROBLEM TO BE SOLVED: To provide a low noise coaxial cable which can perform a high speed signal transmission, does not damage flexibility, and easily performs a terminal processing. SOLUTION: This cable 10 comprises: an inner conductor 2; a dielectric layer 3 which covers the circumference of inner conductor 2; a plastically deformable semi-conductive layer 4 which is formed around the dielectric layer 3; an outer conductor layer 5 which is formed around the semi-conductive layer 4; and a jacket 6 which is covered around the outer conductor layer 5. The outer conductor layer 5 is inserted into the semi-conductive layer 4 so as to be brought into close contact with the dielectric layer 3.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a foam coaxial cable effectively by regulating the thickness of a silicone oil coating applied to the surface around an insulated conductor. SOLUTION: In this method, after a coating of a waterproof silicone oil 6 is formed around an insulated conductor 1 produced by foaming a cellular plastic coating 12 around a conductor 11, a hollow cylindrical outer conductor 3 is formed around it by means of coating coaxially with the conductor 11. In this case, the coating of the silicone oil 6 is formed by a process where an air flow, whose flow velocity can be regulated by a regulator 4, with fine particles of the silicone oil 6 suspended in this air flow, is sprayed to the surface around the insulated conductor 1 and at the same time the particle amount of the silicone oil 6 suspended in the air flow is moderated by the control of the regulator 4 so that the thickness of the coating can be adjusted.

摘要： The present invention is an improved cable for use in accurate signal transmission where limited space may be available for cable termination to a backplane or other interface. The cable of the present invention employs highly effective insulation materials of whatever diameter may be required along the majority of its length, but reduces the diameter of such materials at connective ends of the cable. As a result, very accurate, high speed signal transmission is provided while allowing high density cable attachment at input/output ports. Further, the present invention provides an improved method for rapidly and accurately constructing a cable with changed diameter along its length.
