Coaxial cable connector
First Claim
1. A connector for coupling the end of a coaxial cable to a threaded port wherein the coaxial cable has an axial conductor, a coaxial layer of a dielectric surrounding the conductor, an electrically conductive grounding sheath surrounding the dielectric layer, and a protective outer jacket surrounding the grounding sheath, said connector comprising:
- (a) a connector subassembly comprising;
i) a nut having an axial conduit with an internally threaded leading end and a trailing end;
ii) a tubular shank having an axial conduit, a leading end with a flange thereon disposed concentrically within said axial conduit of said nut, and a trailing end extending rearwardly from said trailing end of said nut, said tubular shank having an annular shoulder on an outer surface thereof disposed rearwardly of and adjacent to said trailing end of said nut, and an annular barb disposed on said outer surface adjacent to said trailing end; and
iii) a slotted body portion having a generally cylindrical shape with a leading end, a trailing end, an axial conduit therebetween, and a plurality of slots extending forwardly from said trailing end, and a first annular locking groove in an outer surface of said body portion; and
iv) a first “
O”
ring disposed between said flange on said tubular shank and said trailing end of said nut; and
(b) a compression sleeve non-releasably attached to said slotted body portion of said connector subassembly, said compression sleeve being a substantially cylindrical member having a leading end, a trailing end and an axial conduit therebetween, said axial conduit having an annular ridge adjacent the leading end thereof that matingly engages said first annular locking groove on said outer surface of said slotted body portion and non-releasably attaches said compression sleeve to said connector subassembly.

Abstract
A compression-type coaxial cable connector having a leading end, a trailing end and integral construction is described. The connector includes a nut at the leading end of the connector, a tubular shank having a flange on a leading end thereof and a barb concentrically disposed on a trailing end, a slotted body portion and a compression sleeve slidably attached to the body portion forming the trailing end of the connector. The connector, and each of the components associated therewith, has an axial conduit coextensive with the length thereof. When the prepared end of a coaxial cable is inserted into the trailing end of the connector conduit and advanced through the conduit into the body portion, the shank separates the outer protective jacket and conductive braid of the cable from the dielectric core and interposes the barbed portion of the tubular shank therebetween. Subsequent advancement of the compression sleeve over the body portion, with the assistance of a compression tool, compresses the cable jacket and braid in two locations providing secure attachment. Following compression, further advancement of the compression sleeve is stopped when an annular ridge within the compression sleeve engages a groove in the outer surface of the slotted body portion, thereby providing a stable mechanical connection between the cable and connector. A first “O” ring disposed between the tubular shank and the nut, and a second “O” ring disposed between the slotted body portion and compression sleeve, provide a moisture seal. The construction of the slotted body portion and the compression sleeve minimizes the possibility of installation errors.
