Abstract
Abstract A plug inner conductor for connection to a tubular inner conductor of a coaxial cable is disclosed. The plug inner conductor includes a spreading sleeve having a slot formed therein which permits the effective diameter of the sleeve to be increased. A clamping cone is inserted through the spreading sleeve and has a shape which will cause the clamping cone to place a radially outward force on the spreading sleeve as the clamping cone is moved axially through the spreading sleeve. The clamping cone is coupled to an inner conductor sleeve in such a manner that the clamping cone is moved axially with respect to the inner conductor sleeve as the inner conductor sleeve is rotated.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A plug inner conductor for connection to a tubular inner conductor of a coaxial cable, said plug inner conductor comprising: a spreading sleeve having a slot formed therein which permits the effective diameter of said sleeve to be increased; a clamping cone inserted through said spreading sleeve, the shape of said spreading sleeve and said clamping cone being such that said clamping cone places a radially outward force on said spreading sleeve, and thereby tends to increase the effective diameter of said spreading sleeve, as said clamping cone is moved axially through said spreading sleeve; an inner conductor sleeve; means for coupling said inner conductor sleeve to said clamping cone in such a manner that said clamping cone is moved axially with respect to said inner conductor sleeve as said inner conductor sleeve is rotated with respect to said clamping cone; and a compression spring located between confronting radial surfaces of said inner conductor sleeve and said spreading cone.
Claim 2
Dependent Claim
159 words
A plug inner conductor for connection to a tubular inner conductor of a coaxial cable, said plug inner conductor comprising: a spreading sleeve having a slot formed therein which permits the effective diameter of said sleeve to be increased; a clamping cone inserted through said spreading sleeve, the shape of said spreading sleeve and said clamping cone being such that said clamping cone places a radially outward force on said spreading sleeve, and thereby tends to increase the effective diameter of said spreading sleeve, as said clamping cone is moved axially through said spreading sleeve; an inner conductor sleeve; means for coupling said inner conductor sleeve to said clamping cone in such a manner that said clamping cone is moved axially with respect to said inner conductor sleeve as said inner conductor sleeve is rotated with respect to said clamping cone; and a compression spring located between confronting radial surfaces of said inner conductor sleeve and said spreading cone.
Claim 3
Dependent Claim
26 words
The plug inner conductor of claim 1, wherein said spreading sleeve has an inner taper which mates with an outer taper formed in said clamping cone.
Claim 4
Dependent Claim
32 words
The plug inner conductor of claim 1, wherein said spreading sleeve has a faceted surface formed on a front edge thereof to facilitate insertion of said clamping cone into said coaxial cable.
Claim 5
Dependent Claim
34 words
The plug inner conductor of claim 1, further including a front contact surface formed on said inner conductor sleeve which limits the distance said inner conductor sleeve may be inserted into said coaxial cable.
Claim 6
Dependent Claim
16 words
The plug inner conductor of claim 1, wherein said spreading sleeve has a roughened outer surface.
Claim 7
Dependent Claim
21 words
The plug inner conductor of claim 1, further including a screwdriver recess formed in the rear end of said clamping cone.
Claim 8
Dependent Claim
21 words
The plug inner conductor of claim 1, further including a wrench socket formed in the rear end of said clamping cone.
Claim 9
Dependent Claim
29 words
The plug inner conductor of claim 1, wherein said coupling means comprises internal and external threads formed on mating portions of said inner conductor sleeve and said clamping cone.
Claim 10
Dependent Claim
32 words
The plug inner conductor of claim 8, wherein said clamping cone has a faceted surface formed on a front edge thereof to facilitate insertion of said clamping cone into said coaxial cable.
