Bulge-type coaxial cable termination assembly
First Claim
1. A cable termination assembly for connecting a cable having an electrically conductive member to another electrically conductive member comprising:
- a connector body having a sleeve member of a generally cylindrical configuration, an end of said cable extending concentrically within said sleeve member, and said sleeve member having an external wall surface portion of generally convex configuration adjacent to one end thereof; and
a cylindrical compression member having an inner annular surface slidable over said sleeve member, said inner annular surface portion engageable with said external wall surface portion of said sleeve member wherein axial advancement of said compression member along said sleeve member will impart inward radial deformation to said sleeve member and force an internal wall surface portion of said sleeve member into a radially inwardly bowed configuration as it contracts into engagement with an external surface portion of said cable.

Abstract
A cable termination assembly is made up of a connector body having a thin-walled outer sleeve with generally convex surface portion toward its entrance end which enables its use with a number of different compression member configurations to effect positive sealed engagement with one end of a cable, exemplary compression members including an inner connector sleeve-engaging wall surface which is of uniform diameter throughout its substantial length, one with a slight concavity at its leading end to facilitate preassembly onto the connector sleeve, and one with a combination of concave and convex surface portions.

11. A fitting for connecting a cable having an electrically conductive member to another electrically conductive member, said fitting comprising:
-
a thin-walled sleeve member of a continuous cylindrical configuration sized for axial insertion of an end of said cable therein, said sleeve member provided with an external convex surface portion thereon and internal sealing rings; and a cylindrical compression member having an inner concave annular surface portion adapted to overlie said external convex surface portion in preassembled relation to said sleeve member, and said compression member further having a first inner surface portion of substantially uniform diameter in trailing relation to said concave surface portion wherein axial advancement of said compression member along said sleeve member forces said first inner surface portion to move into engagement with said external convex surface portion will impart inward radial deformation to said sealing ribs into inwardly bowed configuration as said ribs are contracted into sealed engagement with said cable. - View Dependent Claims (12, 13, 14, 15)

16. A cable termination assembly for connecting a coaxial cable to a terminal wherein said cable has an outer resilient jacket, inner and outer spaced electrically conductive portions and wherein a connector body has a fastener for connection to said terminal and 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 having a first external wall surface portion of a uniform diameter and a second external wall surface portion of generally convex configuration substantially coextensive with said sealing ribs; and an annular compression member having an inner liner of a substantially uniform diameter corresponding to said diameter of said first external wall surface portion wherein slidable axial advancement of said compression member with respect to said outer sleeve member will impart inward radial deformation to said external wall surface portion and force said axially spaced sealing ribs into inwardly bowed configuration as said ribs are contracted into sealed engagement with an external surface of said cable. - View Dependent Claims (17, 18, 19, 20, 21)
