Connector and coaxial cable with molecular bond interconnection

Abstract

A coaxial connector in combination with a coaxial cable is provided with an inner conductor supported coaxial within an outer conductor, a polymer jacket surrounding the outer conductor. A unitary connector body with a bore is provided with an overbody surrounding an outer diameter of the connector body. The outer conductor is inserted within the bore. A molecular bond is formed between the outer conductor and the connector body and between the jacket and the overbody. An inner conductor end cap may also be provided coupled to the end of the inner conductor via a molecular bond.

1 . A coaxial connector-cable assembly, comprising:
 a coaxial cable including an inner conductor, an outer conductor surrounding the inner conductor, and a dielectric material separating the inner conductor from the outer conductor, each of the inner and outer conductors having an end portion;   a coaxial connector including an inner contact in electrical connection with the inner conductor of the cable and connector body, the connector body having a bore with an inner diameter;   wherein a welded seam is located between the end portion of the outer conductor of the cable and the inner diameter of the bore of the connector body.   
     
     
         2 . The assembly defined in  claim 1  wherein the seam is located along an electrical interconnection between the outer conductor of the cable and the connector body. 
     
     
         3 . The assembly defined in  claim 1 , wherein the seam directly contacts the end portion of the outer conductor. 
     
     
         4 . The assembly defined in  claim 1 , wherein the seam directly contacts the inner diameter of the bore of the connector body. 
     
     
         5 . The assembly defined in  claim 1 , wherein the seam is created by a laser beam that is oriented generally parallel with the inner and outer conductors of the cable. 
     
     
         6 . A coaxial connector for interconnection with a coaxial cable with a solid outer conductor, comprising:
 a monolithic connector body with a bore; and   an overbody of polymeric material on an outer diameter of the connector body;   wherein the overbody is directly molded onto the connector body and extends from a cable end of the connector body.   
     
     
         7 . The connector of  claim 6 , wherein the overbody includes an alignment cylinder of a connection interface at a connector end of the connector. 
     
     
         8 . The connector of  claim 6 , wherein the overbody includes a plurality of longitudinal support ridges extending from an outer diameter of the overbody to less than an inner diameter of a coupling nut dimensioned to seat upon the support ridges. 
     
     
         9 . The connector of  claim 8 , wherein the coupling nut is retained on the support ridges between a flange of the overbody and an outward extending retention spur proximate a cable end of at least one of the support ridges. 
     
     
         10 . The connector of  claim 6 , wherein the inner diameter of the overbody extending from the cable end of the connector body is provided as a friction surface with an interference fit upon an outer diameter of a jacket of the coaxial cable. 
     
     
         11 . The connector of  claim 10 , wherein the friction surface is provided as a series of spaced apart annular peaks of a contour pattern of the inner diameter of the overbody.
