Abstract
Abstract A tubing connector having an explosion chamber adapted to grip the connector firmly to the tubing after a charge within the chamber is exploded. One form of the invention provides a ferrule on the connector so that expansion of the explosion chamber deforms the tubing wall into gripping contact with the ferrule. An annular sealing member may be provided between the ferrule and tubing wall, and the ferrule surface may be rippled. An O-ring seal may also be provided whereby the expanded chamber forces the seal into sealing engagement with the connector and tubing wall.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
An explosion connector attachable to a tubular member comprising the combination of: a body member having a connecting fitting; an explosion chamber connected with the body member and expandable into circumferential gripping relationship with the tubular member; explosive means within the chamber to expand the chamber; and said chamber being annularly disposed around the outside of the tubular member and including a relatively nondeformable outer wall and a relatively deformable inner wall in which the inner wall is deformed into gripping relatioNship with the tubular member upon actuation of the explosive means.
Claim 2
Dependent Claim
92 words
An explosion connector attachable to a tubular member comprising the combination of: a body member having a connecting fitting; an explosion chamber connected with the body member and expandable into circumferential gripping relationship with the tubular member; explosive means within the chamber to expand the chamber; and said chamber being annularly disposed around the outside of the tubular member and including a relatively nondeformable outer wall and a relatively deformable inner wall in which the inner wall is deformed into gripping relatioNship with the tubular member upon actuation of the explosive means.
Claim 3
Dependent Claim
35 words
The invention of claim 1 and further including an annular seal between the chamber and the tubular member whereby expansion of the chamber forces the seal into sealing engagement between the chamber and tubular member.
Claim 4
Dependent Claim
45 words
The invention of claim 1 and further including an O-ring seal positioned between the chamber and tubular member and in abutting relationship with the body member whereby deformation of the inner wall forces the seal into sealing engagement with the tubular member and body member.
Claim 5
Dependent Claim
30 words
The invention of claim 1 wherein the tubular member is deformable, and the body member includes a ferrule aligned along the tubular member on the opposite side from the chamber.
Claim 6
Dependent Claim
30 words
The invention of claim 4 wherein the ferrule is positioned inside of the tubular member whereby expansion of the chamber forces the tubular member into gripping relationship with the ferrule.
Claim 7
Dependent Claim
32 words
The invention of claim 4 wherein the ferrule surface adjacent the tubular wall is formed with an uneven surface and the tubular member is deformed into conforming relationship with the ferrule surface.
Claim 8
Dependent Claim
11 words
The invention of claim 6 wherein the ferrule surface is rippled.
Claim 9
Dependent Claim
18 words
The invention of claim 4 and further including an annular seal positioned between the ferrule and tubular member.
Claim 10
Dependent Claim
25 words
The invention of claim 6 and further including an annular seal positioned between the ferrule and tubular member, said seal conforming to the ferrule surface.
Claim 11
Dependent Claim
45 words
The invention of claim 4 and further including an O-ring seal positioned between the chamber and tubular member and in axial abutment with the body member whereby expansion of the chamber forces the O-ring seal into sealing engagement with the tubular member and body member.
