Abstract

A connector for a conduit having an annular corrugated outer casing includes a clamping member which fits over an end of the casing, a ring split in one place along its circumference which fits into a corrugation trough, a housing having a conically bevelled clamping surface for engaging an inner surface of the last corrugation of the cable, and cooperating threaded portions on the clamping member and housing. Threading of the housing over the clamping member serves to draw and hold the conically bevelled clamping surface and a clamping surface of the split ring together against opposite surfaces of the outer conductor of the cable.

Claims

1. A connector assembly for a conduit having an annularly corrugated outer casing, comprising:

a clamping member which includes a pressing surface;

a housing having a bevelled clamping surface positioned to engage an end of a last corrugation of said conduit;

a split ring positioned adjacent the last corrugation; and

means on said housing and said clamping member for releasably securing said housing to said clamping member,

wherein when the clamping member is secured to the housing by said releasably securing means, the pressing surface presses said split ring against said last corrugation, whereupon the last corrugation is caused to engage the bevelled clamping surface, and the last corrugation is thereby clamped between the split ring and the bevelled clamping surface.

2. A connector assembly as claimed in claim 1, wherein said releasably securing means comprises threaded surfaces on said housing and said clamping member.

3. A connector assembly as claimed in claim 1, wherein said threaded surface on said clamping member is on an exterior surface of said clamping member, and wherein said threaded surface on said housing is on an interior surface of said housing.

4. A connector assembly as claimed in claim 1, wherein said split ring is fitted in the last trough on an exterior of the casing, the last corrugation being a peak.

5. A connector assembly as claimed in claim 1, wherein the bevelled surface forms an obtuse angle with the longitudinal axis of the connector assembly in the direction of insertion.

6. A connector assembly as claimed in claim 1, wherein said beveled surface forms a section of a cone.

7. A connector assembly as claimed in claim 1, wherein said clamping member is fitted over one end portion of the casing which includes said last corrugation.

8. A connector assembly as claimed in claim 1, wherein said beveled clamping surface engages an inside surface of said last corrugation.

9. A connector assembly as claimed in claim 1, wherein said housing further includes a tapered camming surface positioned so as to cause said split ring to radially compress as said ring is pressed into the connector housing in order to prevent rotation of the ring around the conduit.

10. A connector assembly as claimed in claim 1, wherein said bevelled clamping surface is a surface of a discrete part formed separately from the interior surface of the housing, and wherein said surface is continuous around an entire circumference of the conduit.

11. A connector assembly as claimed in claim 1, wherein said conduit is a coaxial cable and said casing is an annularly corrugated outer conductor concentrically spaced from a solid inner conductor by a dielectric, and wherein said housing is made of a conductive material.

12. A connector assembly as claimed in claim 11, wherein said bevelled clamping surface is formed as an integral part of an interior surface of the housing and is continuous around an entire circumference of the cable to ensure electrical contact between the housing and the outer conductor.

13. A connector assembly as claimed in claim 11, wherein said housing further includes an inner contact which engages said inner conductor when said outer conductor is clamped between said clamping surface and said split ring.

14. A connector assembly as claimed in claim 11, wherein said releasably securing means comprises threaded surfaces on said housing and said clamping member.

15. A connector assembly as claimed in claim 11, wherein said threaded surface on said clamping member is on an exterior surface of said clamping member, and wherein said threaded surface on said housing is on an interior surface of said housing.

16. A connector assembly as claimed in claim 11, wherein said split ring is fitted in the last trough on an exterior of the outer conductor, the last corrugation being a peak.

17. A connector assembly as claimed in claim 11, wherein the bevelled surface forms an obtuse angle with the longitudinal axis of the connector assembly in the direction of insertion.

18. A connector assembly as claimed in claim 11, wherein said beveled surface forms a section of a cone.

19. A connector assembly as claimed in claim 11, wherein said clamping member is fitted over one end portion of the outer conductor which includes said last corrugation.

20. A connector assembly as claimed in claim 11, wherein said beveled clamping surface engages an inside surface of said last corrugation.

21. A connector assembly as claimed in claim 11, wherein said housing further includes a tapered camming surface positioned so as to cause said split ring to radially compress as said ring is pressed into the housing in order to prevent rotation of the ring around the cable.

22. A connector assembly as claimed in claim 11, wherein said bevelled clamping surface is a surface of a discrete part formed separately from the interior surface of the housing, and wherein said surface is continuous around an entire circumference of the cable to ensure electrical contact between the housing and the outer conductor.

23. A connector assembly as claimed in claim 22, wherein said interior surface of said housing includes a shelf for positioning said discrete part.

24. A connector assembly as claimed in claim 22, wherein said releasably securing means comprises threaded surfaces on said housing and said clamping member.

25. A connector assembly as claimed in claim 22, wherein said threaded surface on said clamping member is on an exterior surface of said clamping member, and wherein said threaded surface on said housing is on an interior surface of said housing.
