Universal crimping connector
First Claim
1. A multi-stage connector for mechanically and electrically connecting a cable having a first electrically conductive member to a second electrically conductive member, said connector comprising:
- a connector body;
an outer sleeve member extending from an end of said connector body for insertion of an end of said cable therein;
a first crimping member having a first inner crimping surface portion including a first inner diameter at least as great as an outer diameter of said outer sleeve member and disposed in outer surrounding and slidably engaging relation to said outer sleeve member; and
a second crimping member having a second inner crimping surface portion at least partially overlying said first crimping member wherein slidable axial advancement of said second crimping surface portion and said first crimping surface portion with respect to said outer sleeve member will impart inward radial deformation to said outer sleeve member into crimping engagement with an external surface of said cable.

Abstract
A coaxial cable TV connector is made up of one or more crimping members having inner crimping surface portions which are preassembled onto a crimpable sleeve member of a connector body, the sleeve having an external tapered portion into which the coaxial cable is inserted so that the crimping ring(s) can be preassembled onto the sleeve and axially advanced to cause inward radial deformation of the sleeve into sealed engagement with an outer surface of the coaxial cable, and each size of connector assembly is conformable for use with more than one size of cable.

8. In a connector for connecting a coaxial TV cable to a terminal wherein said cable has an outer resilient jacket, inner and outer spaced electrically conductive portions and wherein said connector has a fastener for connection to said terminal and a body provided with inner and outer concentric sleeve members with axially spaced sealing ribs on an inner surface of said outer sleeve member for insertion of said inner electrically conductive portion within said inner sleeve member and insertion of said outer electrically conductive portion and said jacket between said inner sleeve members and said outer sleeve member, the improvement comprising:
-
a first crimping member having a first inner crimping surface portion including a first inner diameter at least as great as an outer diameter of said outer sleeve and a leading end portion disposed in outer surrounding and slidably engaging relation to a trailing end portion of said outer sleeve member; and a second crimping member having a second inner crimping surface portion extending rearwardly from a first diameter at least as great as an outer diameter of said first crimping member to a second diameter less than said outer diameter of said first crimping member but greater than said inner diameter of said outer sleeve member wherein slidable axial advancement of said second crimping member and said first crimping member with respect to said outer sleeve member will impart progressive inward radial deformation to said first crimping member and resultant inward radial deformation of said sealing ribs into sealed engagement with said outer resilient jacket. - View Dependent Claims (9, 10, 11)

12. A fitting for connecting a cable having an electrically conductive member to another electrically conductive member, said fitting comprising:
-
an outer sleeve member of a continuous cylindrical configuration sized for insertion of an end of said cable therein, said sleeve member having a thin-walled portion of substantially uniform diameter and a relatively thick portion tapering away from said thin-walled portion; an inner sleeve member in inner spaced concentric relation to said outer sleeve member; and a cylindrical crimping member having at least one inner crimping surface portion dimensioned to advance over said sleeve member, said inner crimping surface portion disposed in close-fitting slidable engagement with said outer sleeve member whereupon axial advancement of said crimping member along said outer sleeve member will impart inward radial deformation to said outer sleeve member into sealed engagement with an external surface portion of said cable. - View Dependent Claims (13, 14, 15, 16, 17)

18. A connector for connecting a coaxial TV cable to a terminal wherein said cable has an outer resilient jacket, inner and outer spaced electrically conductive portions and wherein said connector has a fastener for connection to said terminal and a body provided with inner and outer concentric sleeve members with axially spaced sealing ribs on an inner surface of said outer sleeve member for insertion of said inner electrically conductive portion within said inner sleeve member and insertion of said outer electrically conductive portion between said inner sleeve member and said outer sleeve member, the improvement comprising:
said outer sleeve member having a thin-wailed sleeve portion and a relatively thick-walled sleeve portion tapering from said thin-walled portion toward an entrance end for insertion of said cable; and
an annular crimping member having a first inner tapered annular surface portion at least as great as an outer diameter of said outer sleeve member and disposed in outer surrounding relation to said outer sleeve member, and a second inner tapered annular surface portion converging rearwardly from said first inner tapered annular surface portion wherein slidable axial advancement of said crimping member with respect to said outer sleeve member will impart inward radial deformation to said outer sleeve member into sealed engagement with an external surface of said cable.- View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
