Abstract

A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by ultrasonic welding is provided with a monolithic connector body with a bore. An annular flare seat is angled radially outward from the bore toward a connector end of the connector, the annular flare seat open to the connector end of the connector. An inner conductor cap is provided for interconnection with an inner conductor of the coaxial cable by ultrasonic welding. The ultrasonic welding of each of the inner and outer conductor interconnections may be performed via inner conductor and outer conductor sonotrodes which are coaxial with one another, without requiring the cable and or connector to be removed from their fixture.

First claim

I claim:

1. A coaxial cable-connector assembly comprising:
a. a coaxial cable comprising an elongate inner conductor and an elongate outer conductor circumferentially surrounding the inner conductor, and an elongate dielectric layer interposed between the inner conductor and the outer conductor, wherein the outer conductor has a leading end; and
b. a coaxial connector comprising:
an inner contact having a first end electrically connected to the inner conductor of the coaxial cable, and a second distal end;
a connector body having a first end that surrounds the leading end of the coaxial cable and a cylindrical distal end that surrounds the second distal end of the inner contact;

wherein an electrical path is formed between the leading end of the outer conductor on the coaxial cable and the cylindrical distal end, and wherein a circumferential welded seam is located along the electrical path.

2. The assembly defined in claim 1 , wherein the circumferential welded seam is formed directly between the leading end of the coaxial cable and the first end of the connector body.

3. The assembly defined in claim 1 , further comprising an overbody that circumferentially overlies the connector body.

4. The assembly defined in claim 1 , wherein the coaxial connector presents a standard 7/16 DIN male interface.

5. The assembly defined in claim 1 , wherein the outer conductor has a smooth profile.

6. A coaxial cable-connector assembly comprising:
a. a coaxial cable comprising an elongate inner conductor and an elongate outer conductor circumferentially surrounding the inner conductor, and an elongate dielectric layer interposed between the inner conductor and the outer conductor, wherein the outer conductor has a leading end; and
b. a coaxial connector comprising:
an inner contact having a first end electrically connected to the inner conductor of the coaxial cable, and a second distal end;
an outer conductive member having a first end that surrounds the leading end of the coaxial cable and a cylindrical distal end that surrounds the second distal end of the inner contact;

wherein an electrical path is formed between the leading end of the outer conductor on the coaxial cable and the cylindrical distal end, and wherein a circumferential welded seam is located along the electrical path.

7. The assembly defined in claim 6 , wherein the circumferential welded seam is formed directly between the leading end of the coaxial cable and the first end of the outer conductive member.

8. The assembly defined in claim 6 , further comprising an overbody that circumferentially overlies the outer conductive member.

9. The assembly defined in claim 6 , wherein the coaxial connector presents a standard 7/16 DIN male interface.

10. The assembly defined in claim 6 , wherein the outer conductor has a smooth profile.

11. A coaxial cable-connector assembly comprising:
a. a coaxial cable comprising an elongate inner conductor and an elongate outer conductor circumferentially surrounding the inner conductor, and an elongate dielectric layer interposed between the inner conductor and the outer conductor, wherein the outer conductor has a leading end; and
b. a coaxial connector comprising:
an inner contact having a first end electrically connected to the inner conductor of the coaxial cable, and a second distal end;
an outer conductive member having a first end that surrounds the leading end of the coaxial cable and a cylindrical distal end that surrounds the second distal end of the inner contact;

wherein an electrical path is formed between the leading end of the outer conductor on the coaxial cable and the cylindrical distal end, and wherein a molecular bond is located along the electrical path.

12. The assembly defined in claim 11 , wherein the molecular bond is formed directly between the leading end of the coaxial cable and the first end of the outer conductive member.

13. The assembly defined in claim 11 , further comprising an overbody that circumferentially overlies the outer conductive member.

14. The assembly defined in claim 11 , wherein the coaxial connector presents a standard 7/16 DIN male interface.

15. The assembly defined in claim 11 , wherein the outer conductor has a smooth profile.
