Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
342 words
A connector for making electrical connection between a conductor and a jacketed electrically conductive shield on a communication cable, said connector comprising: a resilient plate-like conductive first jaw having a base portion, and A relatively flexible elongate symmetrically tapered projecting portion extending from said base portion and terminating in a smaller end, said elongate projecting portion being arcuate about an axis transverse to the width thereof to form a cylindrically concave contact surface adapted for engagement with the inner surface of said shield and having a multiplicity of linear spaced slits oblique to and extending inwardly from its converging edges to form triangular barbs, with each of said barbs being curved to protrude from said contact surface with the point thereof directed generally away from said smaller end; a resilient plate-like second jaw having a base portion, and an elongate symmetrically tapered projecting portion extending from said base portion and terminating in a smaller end, the projecting portion of said second jaw being domed to define a concave contact surface adapted for engagement with the outer surface of the jacket on said communication cable in aligned opposed relationship with said contact surface of said first jaw and having a multiplicity of linear spaced slits oblique to and extending inwardly from its converging edges to form triangular barbs, with each of said barbs being curved to protrude from said concave contact surface with the point thereof directed generally away from the smaller end, the projecting portion of said second jaw being of essentially the same length as the projecting portion of said first jaw and being sufficiently wide to extend over the projecting portion of said first jaw along each converging edge by approximately the width of said barbs formed on said second jaw; and means coupled only between said base portions for connecting said first jaw to said conductor and to said second jaw, and for pressing said jaws into contact with a section of the jacketed shield to engage said barbs and to deflect the projecting portion of said first jaw.
Claim 2
Dependent Claim
342 words
A connector for making electrical connection between a conductor and a jacketed electrically conductive shield on a communication cable, said connector comprising: a resilient plate-like conductive first jaw having a base portion, and A relatively flexible elongate symmetrically tapered projecting portion extending from said base portion and terminating in a smaller end, said elongate projecting portion being arcuate about an axis transverse to the width thereof to form a cylindrically concave contact surface adapted for engagement with the inner surface of said shield and having a multiplicity of linear spaced slits oblique to and extending inwardly from its converging edges to form triangular barbs, with each of said barbs being curved to protrude from said contact surface with the point thereof directed generally away from said smaller end; a resilient plate-like second jaw having a base portion, and an elongate symmetrically tapered projecting portion extending from said base portion and terminating in a smaller end, the projecting portion of said second jaw being domed to define a concave contact surface adapted for engagement with the outer surface of the jacket on said communication cable in aligned opposed relationship with said contact surface of said first jaw and having a multiplicity of linear spaced slits oblique to and extending inwardly from its converging edges to form triangular barbs, with each of said barbs being curved to protrude from said concave contact surface with the point thereof directed generally away from the smaller end, the projecting portion of said second jaw being of essentially the same length as the projecting portion of said first jaw and being sufficiently wide to extend over the projecting portion of said first jaw along each converging edge by approximately the width of said barbs formed on said second jaw; and means coupled only between said base portions for connecting said first jaw to said conductor and to said second jaw, and for pressing said jaws into contact with a section of the jacketed shield to engage said barbs and to deflect the projecting portion of said first jaw.
Claim 3
Dependent Claim
268 words
A connector useful in making an electrical connection between a conductor and a jacketed electrically conductive shield on a communication cable, said connector comprising: a resilient plate-like conductive first jaw having a base portion and a relatively flexible elongate tapered projecting portion extending from the base portion and terminating in a smaller end, said elongate projecting portion being arcuate about an axis transverse to the width thereof to form a cylindrically concave contact surface adapted for engagement with the inner surface of said shield and having a plurality of spaced slits formed along each edge and extending inwardly from said edges away from the base portion at an angle of between 15* to 45 * with the edge to form triangular barbs, with each of said barbs being curved to protrude from said contact surface with the point thereof directed generally away from said smaller end; a resilient plate-like second jaw having a base portion and a projecting portion extending from the base portion and defining a contact surface adapted for engagement with the outer surface of the jacket on said communication cable in aligned opposed relationship with said contact surface of said first jaw, said projecting portion of said second jaw being wider than corresponding portions of the projecting portion of said first jaw; and means coupled only between said portions for connecting said first jaw to said conductor and to said second jaw and for pressing said jaws into contact with a section of the jacketed electrically conductive shield to engage said barbs with said shield and to deflect the projecting portion of said first jaw.
Claim 4
Dependent Claim
268 words
A connector useful in making an electrical connection between a conductor and a jacketed electrically conductive shield on a communication cable, said connector comprising: a resilient plate-like conductive first jaw having a base portion and a relatively flexible elongate tapered projecting portion extending from the base portion and terminating in a smaller end, said elongate projecting portion being arcuate about an axis transverse to the width thereof to form a cylindrically concave contact surface adapted for engagement with the inner surface of said shield and having a plurality of spaced slits formed along each edge and extending inwardly from said edges away from the base portion at an angle of between 15* to 45 * with the edge to form triangular barbs, with each of said barbs being curved to protrude from said contact surface with the point thereof directed generally away from said smaller end; a resilient plate-like second jaw having a base portion and a projecting portion extending from the base portion and defining a contact surface adapted for engagement with the outer surface of the jacket on said communication cable in aligned opposed relationship with said contact surface of said first jaw, said projecting portion of said second jaw being wider than corresponding portions of the projecting portion of said first jaw; and means coupled only between said portions for connecting said first jaw to said conductor and to said second jaw and for pressing said jaws into contact with a section of the jacketed electrically conductive shield to engage said barbs with said shield and to deflect the projecting portion of said first jaw.
Claim 5
Dependent Claim
104 words
The connector of claim 2 wherein the projecting portion of said second jaw is tapered toward a smaller end opposite the base portion thereof, and has a multiplicity of linear spaced slits oblique to and extending inwardly from its converging edges to form triangular barbs positioned along its converging edges, each of said barbs being curved to protrude from said contact surface with the point Thereof directed generally away from said smaller end; and the projecting portion of said second jaw is wider than the corresponding projecting portion of said first jaw by approximately the width of said barbs formed on said second jaw.
Claim 6
