Abstract

A coaxial connector for coaxial cable includes a body with a bore; a sidewall of the bore provided with a cable stop projecting radially inward at least to an inner diameter of the outer conductor; an annular contact groove proximate a cable end side of the cable stop; a contact seated within the contact groove; the contact configured to bias between the contact groove and an outer diameter of the outer conductor; an outer conductor section proximate a cable end side of the contact groove with an inward projecting outer conductor thread; an inner diameter of the outer conductor section greater than the outer diameter of the outer conductor; and a transition at the cable end side of the outer conductor section to a jacket section with an inward projecting jacket thread. An inner diameter of the jacket section is greater than an outer diameter of the jacket.

Claims

1. A coaxial connector for coaxial cable with an inner conductor and a solid outer conductor;

a polymer jacket upon the outer conductor, the coaxial connector comprising;

a body with a bore;

a sidewall of the bore comprising;

a cable stop projecting radially inward at least to an inner diameter of the outer conductor;

an annular contact groove proximate a cable end side of the cable stop;

a contact seated within the contact groove;

the contact configured to bias between the contact groove and an outer diameter of the outer conductor;

an outer conductor section proximate a cable end side of the contact groove with an inward projecting outer conductor thread;

an inner diameter of the outer conductor section greater than the outer diameter of the outer conductor;

a transition at the cable end side of the outer conductor section to a jacket section with an inward projecting jacket thread;

an inner diameter of the jacket section greater than an outer diameter of the jacket.

2. The connector of claim 1, further including an outer conductor lip projecting towards the cable end of the bore from an inner diameter of the cable stop;

the outer conductor lip forming an annular cable groove open to the cable end of the bore.

3. The connector of claim 2, further including a ramp surface on the outer conductor lip.

4. The connector of claim 1, further including an insulator supporting an inner contact configured to couple with the inner conductor.

5. The connector of claim 4, wherein the insulator extends towards the cable end of the bore, under the contact groove.

6. The connector of claim 5, wherein a cable end of the insulator is formed as a plurality of fingers.

7. The connector of claim 1, wherein the outer conductor thread is a self tapping thread.

8. The connector of claim 7, wherein the outer conductor thread has a cable end face and a connector end face;

the connector end face arranged with a slope, with respect to the outer conductor section, that is steeper than the cable end face.

9. The connector of claim 1, wherein the outer conductor thread is formed with a plurality of longitudinal grooves breaking the outer conductor thread continuity.

10. The connector of claim 1, wherein the contact is a circular helical coil spring.

11. The connector of claim 1, wherein the contact is ring with a U-shaped cross section.

12. The connector of claim 1, wherein the contact is a ring with a plurality of spring fingers extending inward.

13. The connector of claim 1, wherein a connector end side of the contact groove has a ramp surface angled towards a connector end of the body.

14. The connector of claim 1, further including an annular gasket groove proximate the cable end of the bore.

15. The connector of claim 14, wherein a connector end side of the gasket groove has a ramp surface angled towards a connector end of the body.

16. The connector of claim 1, wherein a crimp section on an outer diameter of the body corresponds longitudinally to at least a portion of each of the outer conductor section and the jacket section.

17. The connector of claim 1, wherein a crimp section on an outer diameter of the body corresponds longitudinally with the contact groove.

18. A method for installing a coaxial connector upon a coaxial cable with an inner conductor and a solid outer conductor;

a polymer jacket upon the outer conductor, comprising the steps of;

removing a portion of the jacket from an end of the coaxial cable;

inserting the end of the coaxial cable into a bore of a body until a leading edge of the outer conductor contacts an inward projecting outer conductor thread of an outer conductor section of the bore;

threading the outer conductor thread onto the outer conductor until the jacket contacts an inward projecting jacket thread of a jacket section of the bore;

threading the outer conductor thread onto the outer conductor and the jacket thread into the jacket until the leading edge of the outer conductor passes under a contact seated in a contact groove and abuts a cable stop projecting radially inward.

19. The method of claim 18, wherein the threading of the outer conductor thread upon the outer conductor deforms the outer conductor.

20. The method of claim 18, wherein the threading of the outer conductor thread upon the outer conductor cuts into the outer diameter of the outer conductor.
