Compression pressure indicator
First Claim
1. A compression pressure indicator, comprising:
- a compression member;
means for exerting pressure on the compression member in an axial direction;
the compression member being made of a material adapted to be deformed when subjected to pressure to form a seal between surfaces formed by the pressure means in contact with said compression member, the compression member including an indication portion extending from one end thereof and further including a collapsible portion adapted to receive pressure axially from one portion of the pressure means, said pressure means completely surrounding the compression member, the collapsible portion and the indication portion being constructed so as to form a V-shaped channel therebetween, the collapsible portion upon being subjected to a predetermined excessive pressure by said pressure means collapses allowing the compression member to move and fill the V-shaped channel such that at least part of the indication portion is urged out of the pressure means to provide a visual indication that further pressure is not required.

Abstract
A compression pressure indicator includes a compression member which is disposed within a termination and is constructed such that when exposed to a pressure above a predetermined pressure a portion of the compression member protrudes from the termination thus indicating that optimum pressure has been applied inside the termination. The compression member includes an indicator portion and a collapsible portion, the collapsible portion being shaped such that when exposed to a pressure above the predetermined pressure, the collapsible portion collapses thus allowing relative movement between the indicator portion and pressure extending member such that the indicator portion protrudes a predetermined distance from an end of the pressure exerting member.

10. A termination, comprising:
-
a compression member; means for focusing deformation of the compression member; and means for axially driving the compression member against the focusing means so as to deform the compression member; the compression member having a ring-type shape and having an indicator portion at one end thereof, the driving means having a ring-type shape and having an internal diameter on a portion thereof large enough to allow at least part of the indicator portion to be concentrically disposed within the driving means so as to allow the indicator portion to extend therefrom, the compression member having a collapsible portion therein having a strength less than that of the focusing means and said portion of the driving means, the collapsible portion and the indicator portion being constructed so as to form a V-shaped channel therebetween such that when the compression member is pressurized beyond a predetermined amount by movement of the driving means toward the focusing means the collapsible portion collapses against the driving means allowing the compression member to move and thereby fill the V-shaped channel and cause the indicator portion to move at least partially outside of said portion of the driving means. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
