Bulge-type coaxial cable connector

A cable termination assembly for connecting a coaxial cable to a terminal wherein said cable has an outer resilient jacket, inner and outer spaced concentric electrically conductive portions and wherein a connector body has a fastener for connection to said terminal and inner and outer concentric sleeve members having an entrance end with axially spaced sealing ribs on an inner surface of said outer sleeve member adjacent to said fastener and away from said entrance end for insertion of said inner electrically conductive portion within said inner sleeve member and insertion of said outer concentric 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 axially spaced away from said entrance end;
• 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 convex wall surface portion and force said sealing ribs into inwardly bowed configuration as said sealing ribs are contracted into sealed engagement with an external surface of said cable.

In a connector for connecting a coaxial cable to a terminal wherein said cable has an outer resilient jacket, a dielectric layer, inner and outer spaced concentric electrically conductive portions, an extension tip on said inner spaced electrically conductive portion, the improvement comprising:

• said connector having a fastener for connection to said terminal and a body provided with an annular centering guide and inner and outer concentric sleeve members with a slotted ferrule at one end of said inner concentric sleeve member for insertion of said inner electrically conductive portion and dielectric layer within said inner sleeve member and insertion of said outer electrically conductive portion in said jacket between said inner and outer sleeve members;
• said outer concentric sleeve member terminating in a generally convex surface portion at one end opposite to an entrance end thereof and in outer concentric relation to said ferrule;
• and
• a compression member having an inner annular surface portion of a diameter substantially corresponding to said outer sleeve member and movable into surrounding relation to said outer sleeve member and whereupon axial advancement of said compression member along said outer sleeve member will impart inward radial deformation to said generally convex surface portion into sealed engagement with said ferrule after said extension tip has advanced into engagement with said centering guide.
