Abstract

The connector has a nut section and a pin section which screw together. An internal support sleeve within the nut section of the connector floats relative to that section until the pin section of the connector has been fully screwed into the nut section. When a prepared coaxial cable has been inserted into the nut section, and said nut section has been screwed tightly onto the pin section, firm electrical contact will be made to the cable.

Claims

1. A coaxial entrance connector comprising:

a. a pin section adapted to contact the internal conductor of a coaxial cable comprising;

i. spring-loaded conductive jaws adapted to close upon and frictionally engage the internal conductor; and

ii. jaw actuating means within said pin section for closing said jaws upon said internal conductor; and

b. a nut section joined to said pin section to make electrical contact with the outer jacket of a coaxial cable comprising;

i. a body;

ii. a cavity internal to said body;

iii. a substantially tubular first opening at one end of said body extending into said cavity through which a coaxial cable can be passed;

iv. a substantially tubular second opening into said body having internal threads therein which coact with external threads on said pin section to join the pin section to the nut section;

v. a compressible ferrule within said cavity adapted to be clamped onto the outer conductive jacket of a coaxial cable and to make electrical contact with said outer conductive jacket;

vi. a substantially cylindrical support sleeve extending from said cavity through said compressible ferrule and into said first opening;

vii. means for clamping said compressible ferrule onto the outer jacket of a coaxial cable inserted through said first opening into said cavity and onto said support sleeve, whereby the outer jacket of the cable will be sandwiched between said compressible ferrule and said support sleeve; and

viii. a washer-like section on the end of said support sleeve within said cavity having external threads thereon adapted to be screwed through said internal threads of said second opening for preventing said support sleeve from sliding out of said cavity through said first opening while allowing for free rotation of said support sleeve.

2. The coaxial entrance connector of claim 1 further comprising means for sealing said cavity when a coaxial cable has been passed through said first opening.

3. The coaxial entrance connector of claim 2 wherein said means for sealing said cavity comprises a rubber ring adapted to be compressed onto the outer jacket of a coaxial cable.

4. The coaxial entrance connector of claim 3 wherein said rubber ring is constructed of a conductive rubber and is adapted to contact the outer jacket of a coaxial cable passed through said opening and thereby seal said first cavity and prevent the introduction of RFI at said first opening.

5. The coaxial entrance connector of claim 1 wherein said pin section further comprises a substantially tubular conductive portion spaced from and adapted to surround the internal conductor of a coaxial cable.

6. The coaxial entrance connector of claim 5 wherein said outer conductive portion of said pin section has a flat face adapted to contact a flat face of said support sleeve thereby forming a metal-to-metal seal.

7. The coaxial entrance connector of claim 6 wherein said metal-to-metal seal extends for 360* around the internal conductor of a coaxial cable, whereby the introduction of RFI at said seal is precluded.

8. The coaxial entrance connector of claim 1, wherein said jaw actuating means comprises a substantially cylindrical, spring-loaded insulating member having a central bore therein, the bore having an internal bevelled portion into which said jaws extend, said jaws comprising a split, conductive tube whereby external pressure on said insulating portion causes said jaws to close.

9. The coaxial entrance connector of claim 8, wherein said jaws have ridged internal surfaces adapted to frictionally engage an internal conductor of a coaxial cable when said jaws are closed thereon.

10. The coaxial entrance connector of claim 8, wherein said support sleeve is adapted to actuate said spring-loaded jaws.
