Abstract

A two-piece cable connector includes a connector body and a threaded nut or compression fitting that attaches at a first end of the connector body. Two series of rings are interleaved with tapered sides adjacent each other, with the rings being fitted inside the connector body outside a portion of a mandrel. Two plastic rings are fitted adjacent the series of rings at the first end of the connector body. The threaded nut or compression fitting drives the plastic rings against each other and the inboard ring against the series of rings in wedging engagement, thus creating an interference fit among the grounded connector body, the series of rings, a ground sheath of a coaxial cable, and the mandrel. The two plastic rings form a seal protecting the inside of the cable connector from the environment.

Claims

AMENDED CLAIMS [received by the International Bureau on 31 August 2005 (31.08.05);
Claims 1 and 18 are replaced by amended claims 1 and 18, new claims 30-38 have been added, remaining claims unchanged (4 pages) ]
1. A cable connector, comprising: a connector body having a cavity therein; a mandrel fitted inside said cavity for receiving a prepared coaxial cable end at an end of said connector body; a first plurality of rings fitted between a portion of said mandrel and said connector body and a second plurality of rings fitted between said portion of said mandrel and said connector body, said first plurality of rings and said second plurality of rings having wedge-shaped cross-sections; said first plurality of rings and said second plurality of rings being interleaved with one another so that adjacent surfaces of first plurality of rings and said second plurality of rings are in tapered relationship with each other; at least one of said first plurality of rings being of electrically conductive material; a first sealing ring having a wedge-shaped cross section adjacent to one of said second plurality of rings and in tapered relationship with said one of said second plurality of rings, said first sealing ring being closer to said end of said connector body than said first and second pluralities of rings; a second sealing ring adjacent said first sealing ring, said second sealing ring being closer to said end of said connector body than said first sealing ring, and said second sealing ring having a surface in tapered relationship with a tapered surface of said first sealing ring; and driving means, attached to said connector body at said end of said connector body, for driving said second sealing ring into wedging engagement with said first sealing ring, thereby driving said first sealing ring to drive said first and second pluralities of rings into wedging engagement with each other.
2. A cable connector according to claim 1, wherein said first plurality of rings are gapped.
13. A cable connector according to claim 1, wherein said mandrel is of plastic.

17. A cable connector according to claim 1, further comprising a thrust bearing disposed between said second plurality of rings and a wall of said cavity of said connector body.
18. A method for constructing a cable connector, comprising the steps of: providing a connector body having a cavity therein; providing a mandrel fitted inside said cavity for receiving a prepared coaxial cable end at an end of said connector body; providing a first plurality of rings fitted between a portion of said mandrel and said connector body and a second plurality of rings fitted between said portion of said mandrel and said connector body, wherein said first plurality of rings and said second plurality of rings have wedge-shaped cross-sections, and wherein at least one of said first plurality of rings are of electrically conductive material; interleaving said first plurality of rings and said second plurality of rings with one another so that adjacent surfaces of first plurality of rings and said second plurality of rings are in tapered relationship with each other; providing a first sealing ring having a wedge-shaped cross section adjacent to one of said second plurality of rings and in tapered relationship with said one of said second plurality of rings, said first sealing ring being closer to said end of said connector body than said first and second pluralities of rings; providing a second sealing ring adjacent said first sealing ring, said second sealing ring being closer to said end of said connector body than said first sealing ring,
16
27. A method according to claim 18, further comprising providing a plurality of spring leafs biasing between a collet in said connector and said mandrel.
28. A method according to claim 18, wherein said mandrel is of plastic and said plurality of spring leafs and said mandrel are one-piece.
29. A method according to claim 18, further comprising the step of preventing an exposed center conductor in said prepared cable end from making electrical contact with any grounded portions of said cable connector while connecting said coaxial cable end to said cable connector.
30. A cable connector, comprising: a connector body having an inner cavity; a mandrel fitted inside said cavity for receiving a prepared coaxial cable end at an end of said connector body; a plurality of inner rings operatively associated with at least one outer ring, said inner and outer rings located within the inner cavity and being interleaved with one another so that the side surfaces of adjacent rings are in a wedging relationship; and a compression member operatively engaged to said connector body for driving said inner and outer rings into wedging engagement with each other whereby at least one of said rings forms a continuous seal with the coaxial cable.
31. A cable connector according to claim 30, wherein said inner rings have a substantially wedge-shaped cross-section.
32. A cable connector according to claim 30, wherein at least one of said inner rings is composed of electrically conductive material.
33. A cable connector according to claim 30, further including a means for attaching the connector to an equipment port.
17
34. A cable connector according to claim 33, further including a conductive pin electrically engaging the center conductor of coaxial cable.
35. A cable connector according to claim 34, wherein the conductive pin includes a collet for receiving an end of the center conductor of the coaxial cable.
36. A cable connector according to claim 34, further including an insulator to electrically isolate the conductive pin from the connector body.
37. A method for installing a cable connector on a cable, comprising the steps of: providing a connector body having a cavity therein; providing a mandrel fitted inside said cavity for receiving a prepared coaxial cable end at an end of said connector body; providing a plurality of inner rings operatively associated with at least one outer ring located within the inner cavity; interleaving said inner and outer rings with one another so that adjacent side surfaces of said rings are in wedging relationship with each other; and driving said inner and outer rings into wedging engagement with each other.
38. A method according to claim 37, further comprising the step of providing at least one of said rings that is circular and composed of a deformable material whereby upon driving said inner and outer rings into wedging engagement, said deformable ring forms a continuous seal with the cable.
