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 (30)

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.
