Abstract
Abstract The containment, splicing, or termination of the line is achieved by selective crimping along a housing. In a preferred form, the housing comprises a crimp barrel having a series of axially displaced apertures formed therein. A line, e.g. a wire, is inserted in the barrel, and a force is applied in registration with each aperture to deform the barrel and the line so that the deformed portion of the barrel maintains the deformed portion of the line against the aperture. The line scrapes against edges of the aperture to form a tight joint.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
208 words
A mechanical connection comprising, in combination: a generally tubular, deformable housing said housing forming a line passageway therein, said housing having first and second end openings therein adapted for the admittance of at least one line, said passageway being of slightly larger diameter than said lines to be admitted; at least one aperture formed in said housing and axially spaced from said end openings, said aperture intersecting said line passageway and having a sharp tapered edge formed at said intersection between said aperture and said line passageway; said aperture being an excision extending through the exterior of said housing and being formed along an axis transverse to and laterally spaced from the exterior of said housing, at least one line axially disposed in said housing passageway; non-perforating deformations formed in said housing such that a point of said housing opposite each of said aperture is deformed inwardly and the portion of said line in registration therewith is deformed such that said line projects into said aperture and engages an interface of said aperture with said housing, and said point of said housing oposite each of said apertures is deformed to a distance from said aperture which is less than the diameter of said line disposed within said housing.
Claim 2
Dependent Claim
208 words
A mechanical connection comprising, in combination: a generally tubular, deformable housing said housing forming a line passageway therein, said housing having first and second end openings therein adapted for the admittance of at least one line, said passageway being of slightly larger diameter than said lines to be admitted; at least one aperture formed in said housing and axially spaced from said end openings, said aperture intersecting said line passageway and having a sharp tapered edge formed at said intersection between said aperture and said line passageway; said aperture being an excision extending through the exterior of said housing and being formed along an axis transverse to and laterally spaced from the exterior of said housing, at least one line axially disposed in said housing passageway; non-perforating deformations formed in said housing such that a point of said housing opposite each of said aperture is deformed inwardly and the portion of said line in registration therewith is deformed such that said line projects into said aperture and engages an interface of said aperture with said housing, and said point of said housing oposite each of said apertures is deformed to a distance from said aperture which is less than the diameter of said line disposed within said housing.
Claim 3
Dependent Claim
12 words
The joint of claim 1 wherein said housing comprises a splice barrel.
Claim 4
Dependent Claim
29 words
The joint according to claim 2 wherein first and second line ends are axially disposed in opposite ends of said splice barrel and crimped whereby a splice is provided.
Claim 5
Dependent Claim
23 words
A joint according to claim 2 wherein said lines comprise electrically insulated wires and insulation is scraped from said wire at said interface.
Claim 6
Dependent Claim
172 words
A mechanical connection device comprising: a generally tubular housing forming a line passageway therein said housing having first and second end openings therein adapted for the admittance of at least one line, said passageway being of slightly larger diameter than said lines to be admitted; said housing having at least one axially spaced aperture formed in said housing and axially spaced from said openings, said aperture being an ercision extending through the exterior of said housing and being formed along an axis transverse to and laterally spaced from the exterior of said housing said aperture intersecting said line passageway and having a sharp tapered edge formed at said intersection between said aperture and said line passageway; said housing being further defined as being deformable whereby a portion of said housing opposite said aperture may be indented in registration with said aperture such that a line contained within said housing line passageway is deformed so as to provide for the engagement of said line at the interface of said aperture and said housing.
Claim 7
Dependent Claim
172 words
A mechanical connection device comprising: a generally tubular housing forming a line passageway therein said housing having first and second end openings therein adapted for the admittance of at least one line, said passageway being of slightly larger diameter than said lines to be admitted; said housing having at least one axially spaced aperture formed in said housing and axially spaced from said openings, said aperture being an ercision extending through the exterior of said housing and being formed along an axis transverse to and laterally spaced from the exterior of said housing said aperture intersecting said line passageway and having a sharp tapered edge formed at said intersection between said aperture and said line passageway; said housing being further defined as being deformable whereby a portion of said housing opposite said aperture may be indented in registration with said aperture such that a line contained within said housing line passageway is deformed so as to provide for the engagement of said line at the interface of said aperture and said housing.
