Abstract

An end connector for coaxial cable, attached thereto by a compression crimp urging engagement between a threaded inner wall of an outer sleeve of the connector and utilizing a deformable O-ring captively positioned between a backside of a ground conductor plate and an inner edge of an inwardly flanged shoulder portion of a connector nut. Upon connection of the connector of the present invention to its mating connector, pressure applied to the ground plate platform deforms the O-ring, thereby urging improved electrical contact between ground plate platforms of respective connectors while preventing introduction of unwanted contaminants into the conductor.

Claims

1. An end connector for a coaxial cable, comprising:

radially inner and outer spaced generally cylindrical sleeves, open at a first end, the inner sleeve being sized to receive at the first end an inner conductor and an annular dielectric of the coaxial cable, the outer sleeve being sized to receive an outer conductor and an insulating jacket of the coaxial cable, and

coupling means for coupling connectors having an inner and an outer surface, the inner surface formed to captively accept a matingly corresponding outer surface of a mating connector, the coupling means being attached to the radially inner and outer spaced sleeves at their second ends,

an annular conductive surface integral to the inner sleeve, disposed at the second end of the inner sleeve and extending radially outwardly in a plane essentially perpendicular to the axis about which the inner and outer sleeves are disposed, the annular conductive surface having a first planar side and a second planar side the first planar side being positioned for contact with a corresponding, inner conductive surface of the mating connector

an O-ring disposed about the inner sleeve adjacent to the second planar side of the annular conductive surface and the inner surface of the coupling means, the O-ring forming an environmental seal therebetween upon coupling by the coupling means with the corresponding mating connector, which coupling means compresses the second planar side of the annular conductive surface and the O-ring into a sealed arrangement with the coupling means, and

means for affixing the end connector to the coaxial cable.

2. The end connector of claim 1 wherein the outer perimeter of the annular conductive surface extends backwardly toward the first end of the inner sleeve opposite the annular surface in a manner so as to be perpendicular, at any given point, to the annular surface, thereby forming an annular groove about the inner sleeve said groove defined on three sides by the exterior of the inner sleeve, the annular surface and the backwardly extending portion.

3. The end connector of claim 2 wherein the O-ring is disposed within the annular groove.

4. The end connector of claim 1 wherein the O-ring is formed of a pliable material resistant to and recoverable from deformation, said material is also resistant to deterioration from exposure to environmental elements.

5. The end connector of claim 1 wherein the affixing means comprises an inner surface of the outer sleeve having screw-type threads disposed thereon, said threads, when compressed onto the insulating jacket of the coaxial cable, create an environmental seal.

6. The end connector of claim 5 wherein the threads are disposed along substantially the entire length of the inner surface of the outer sleeve.

7. The end connector of claim 1 wherein the end connector is attached to the coaxial cable by a compression-type crimp.

8. The end connector of claim 7 wherein the compression-type crimp is applied uniformly along substantially the entire length of the outer surface of the outer sleeve.

9. An end connector for a coaxial cable, comprising:

radially inner and outer spaced generally cylindrical sleeves, open at a first end, the inner sleeve being spaced to receive at the first end an inner conductor and an annular dielectric of the coaxial cable, the outer sleeve being sized to receive an outer conductor and an insulating jacket of the coaxial cable, and

coupling means for coupling connectors having an inner and outer surface, the inner surface formed to captively accept a matingly corresponding outer surface of a mating connector, the coupling means being attached to the radially inner and outer spaced sleeves at their second end,

an annular conductive surface integral to the inner sleeve, disposed at the second end of the inner sleeve and extending radially outwardly in a plane essentially perpendicular to the axis about which the inner and outer sleeves are disposed, wherein the outer perimeter of the annular conductive surface extends backwardly toward a cable insertion end of the outer sleeve in a manner so as to be generally perpendicular to the annular surface; and

means for affixing the end connector to the coaxial cable.

10. The end connector of claim 9 further comprising a deformable O-ring disposed about the inner sleeve adjacent to the annular conductive surface.

11. The end connector of claim 10 wherein the O-ring is located within an annular groove defined on three sides by the exterior of the inner sleeve, the annular surface and the backwardly extending portion.

12. The end connector of claim 10 wherein the O-ring is formed of a pliable material resistant to and recoverable from deformation, said material is also resistant to deterioration from exposure to environmental elements.

13. The end connector of claim 9 wherein the affixing means comprises an inner surface of the outer sleeve having screw-type threads disposed thereon, said threads, when compressed onto the insulating jacket of the coaxial cable, create an environmental seal.

14. The end connector of claim 13 wherein the threads are disposed along substantially the entire length of the inner surface of the outer sleeve.

15. The end connector of claim 9 wherein the end connector is attached to the coaxial cable by a compression-type crimp.

16. The end connector of claim 15 wherein the compression-type crimp is applied uniformly along substantially the entire length of the outer surface of the outer sleeve.
