Abstract
A coaxial cable of the present invention comprises a center conductor, a dielectric surrounding the center conductor, a shielding tape surrounding the dielectric, a braided metal surrounding the shielding tape, and an outer jacket surrounding the braided metal. The shielding tape comprises: (i) a first shielding layer bonded to a first separating layer; (ii) a second shielding layer bonded to the first separating layer and a second separating layer; and (iii) a third shielding layer bonded to the second separating layer.
Claims20
A coaxial cable comprising:
- a conductor;
- a dielectric surrounding the conductor;
- a shielding tape surrounding the dielectric, the shielding tape manufactured by a method including:
- exposing a first surface of a first separating layer to a first corona discharge;
- applying a first adhesive to at least one of the exposed first surface of the first separating layer or a first surface of a first shielding layer;
- pressing the first surface of the first shielding layer against the first surface of the first separating layer after application of the first adhesive;
- exposing a second surface of the first separating layer to a second corona discharge;
- applying a second adhesive to at least one of the exposed second surface of the first separating layer or a first surface of a second shielding layer;
- pressing the first surface of the second shielding layer against the second surface of the first separating layer after application of the second adhesive;
- exposing a first surface of a second separating layer to a third corona discharge;
- applying a third adhesive to at least one of the exposed first surface of the second separating layer or a first surface of a third shielding layer;
- pressing the first surface of the third shielding layer against the first surface of the second separating layer after application of the third adhesive;
- exposing a second surface of the second separating layer to a fourth corona discharge;
- applying a fourth adhesive to at least one of the exposed second surface of the second separating layer or a second surface of the second shielding layer;
- and
- pressing the second surface of the second shielding layer against the second surface of the second separating layer after application of the fourth adhesive;
- a braided metal surrounding the shielding tape;
- and
- an outer jacket surrounding the braided metal.

- a dielectric surrounding the conductor;
- a shielding tape surrounding the dielectric, the shielding tape manufactured by a method including:
- activating a first surface of a first separating layer to etch the first surface of the first separating layer;
- applying a first adhesive to at least one of the etched first surface of the first separating layer or a first surface of a first shielding layer;
- pressing the first surface of the first shielding layer against the first surface of the first separating layer after application of the first adhesive;
- activating a second surface of the first separating layer to etch the second surface of the first separating layer;
- applying a second adhesive to at least one of the etched second surface of the first separating layer or a first surface of a second shielding layer;
- pressing the first surface of the second shielding layer against the second surface of the first separating layer after application of the second adhesive;
- activating a first surface of a second separating layer to etch the first surface of the second separating layer;
- applying a third adhesive to at least one of the etched first surface of the second separating layer or a second surface of the second shielding layer;
- pressing the second surface of the second shielding layer against the first surface of the second separating layer after application of the third adhesive;
- activating a second surface of the second separating layer to etch the second surface of the second separating layer;
- applying a fourth adhesive to at least one of the etched second surface of the second separating layer or a first surface of a third shielding layer;
- and
- pressing the first surface of the third shielding layer against the second surface of the second separating layer after application of the fourth adhesive, wherein, after the pressing steps, the first and second separating layers and the first, second and third shielding layers form a lamination in which the first, second and third shielding layers are individually separated from each other by the first and second separating layers.
