Abstract
Abstract An electrically conductive joint between a conductor and a connector includes a metallic tube and a crimp in the tube to secure a conductor therein. The crimp has a V-shaped outer portion and a substantially V-shaped inner portion including converging walls and a truncated apex with the angle of the inner and outer V-shaped portions being substantially the same. The conductor is secured within the tube in a substantially gas impervious relationship for use in pneumatically operated probe carrying fixtures for testing printed circuit boards.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
An electrically conductive joint between a conductor and a connector, comprising: (a) a metallic tube including a seamless ferrule adjacent to one end to receive a conductor; (b) a crimp in said tube to secure said conductor within said ferrule; (c) said crimp including a substantially V-shaped outer crimp portion; and (d) said crimp including an inner crimp portion of substantially V-shaped and having converging walls and a truncated apex, said inner crimp portion engaging said outer crimp portion except in the area of said truncated apex; (e) whereby said conductor is secured within said tube in a substantially gas impervious relationship.
Claim 2
Dependent Claim
102 words
An electrically conductive joint between a conductor and a connector, comprising: (a) a metallic tube including a seamless ferrule adjacent to one end to receive a conductor; (b) a crimp in said tube to secure said conductor within said ferrule; (c) said crimp including a substantially V-shaped outer crimp portion; and (d) said crimp including an inner crimp portion of substantially V-shaped and having converging walls and a truncated apex, said inner crimp portion engaging said outer crimp portion except in the area of said truncated apex; (e) whereby said conductor is secured within said tube in a substantially gas impervious relationship.
Claim 3
Dependent Claim
33 words
The joint set forth in claim 1 wherein: said conductor is formed of a malleable material flowable under pressure and which flows into a sealing relationship in the area of said truncated apex.
Claim 4
Dependent Claim
28 words
The joint set forth in claim 1 wherein: said tube has a substantially circular open end receiving said conductor and said crimp is spaced from said open end.
Claim 5
Dependent Claim
23 words
The joint set forth in claim 1 wherein: said truncated apex has a reverse curve which is concave with respect to said conductor.
Claim 6
Dependent Claim
35 words
The joint as set forth in claim 1 wherein: said conductor is formed of a malleable material flowable under pressure and which flows into a vacuum sealing relationship in the area of said truncated apex.
Claim 7
Dependent Claim
97 words
An electrically conductive joint between a conductor and a connector, comprising: (a) a metallic tube having an open seamless end to receive said conductor; (b) a crimp in said tube set back from said open end and including a substantially V-shaped outer crimp portion; (c) an inner crimp portion of substantially V-shape and having converging walls and a truncated apex of reverse curvature which is concave to said conductor, said conductor being secured between said outer crimp portion and said truncated apex; (d) whereby said conductor is secured within said crimp in a substantially gas impervious relationship.
Claim 8
Dependent Claim
97 words
An electrically conductive joint between a conductor and a connector, comprising: (a) a metallic tube having an open seamless end to receive said conductor; (b) a crimp in said tube set back from said open end and including a substantially V-shaped outer crimp portion; (c) an inner crimp portion of substantially V-shape and having converging walls and a truncated apex of reverse curvature which is concave to said conductor, said conductor being secured between said outer crimp portion and said truncated apex; (d) whereby said conductor is secured within said crimp in a substantially gas impervious relationship.
Claim 9
Dependent Claim
123 words
An electrically conductive joint between a conductor and a connector, comprising: (a) a metallic tube having an open seamless end to receive a conductor; (b) a crimp in said tube set back from said open end and including a substantially V-shaped outer portion having outer arms and an outer apex; (c) an inner crimp portion of substantially V-shape and including inner arms and a truncated inner apex; said conductor being secured between said inner and outer apexes; (d) said inner arms being bent back approximately one hundred and eighty degrees and said inner and outer arms extending parallel to one another for at least a portion of said crimp; (e) whereby said conductor is secured within said crimp in substantially gas impervious relationship.
Claim 10
Dependent Claim
123 words
An electrically conductive joint between a conductor and a connector, comprising: (a) a metallic tube having an open seamless end to receive a conductor; (b) a crimp in said tube set back from said open end and including a substantially V-shaped outer portion having outer arms and an outer apex; (c) an inner crimp portion of substantially V-shape and including inner arms and a truncated inner apex; said conductor being secured between said inner and outer apexes; (d) said inner arms being bent back approximately one hundred and eighty degrees and said inner and outer arms extending parallel to one another for at least a portion of said crimp; (e) whereby said conductor is secured within said crimp in substantially gas impervious relationship.
