Abstract
Abstract A method for bonding a copper terminal member to an aluminum electrical conductor wire. The copper member, having a point at one end, is driven with its pointed end into the terminal end of the aluminum wire, so that a cold weld is produced between the aluminum and copper which forms a good electrical connection.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
75 words
A method of making an electrical connection with a solid aluminum conductor which comprises forcing an electrical conducting metal member having a tapered portion into said solid aluminum conductor, so that the surface of said tapered portion which penetrates into the interior of said solid aluminum conductor is scraped clean by the friction of such forced penetration and forms thereby a cold welded joint with the contiguous substantially non-oxidized surface of said solid aluminum conductor.
Claim 2
Independent Claim
75 words
A method of making an electrical connection with a solid aluminum conductor which comprises forcing an electrical conducting metal member having a tapered portion into said solid aluminum conductor, so that the surface of said tapered portion which penetrates into the interior of said solid aluminum conductor is scraped clean by the friction of such forced penetration and forms thereby a cold welded joint with the contiguous substantially non-oxidized surface of said solid aluminum conductor.
Claim 3
Dependent Claim
19 words
A method as defined in claim 1, wherein said metal member has a hardness greater than said aluminum conductor.
Claim 4
Dependent Claim
13 words
A method as defined in claim 2, wherein said metal member is copper.
Claim 5
Dependent Claim
27 words
A method as defined in claim 2, wherein said metal member has a coating thereon of a metal selected from the group consisting of tin and indium.
Claim 6
Dependent Claim
22 words
A method as defined in claim 2, wherein said metal member is selected from the group consisting of steel, brass and bronze.
Claim 7
Dependent Claim
43 words
A method as defined in claim 3, said aluminum conductor and said copper member being in the form of wires, the diameter of the copper wire being smaller than the diameter of the aluminum wire and said tapered portion thereof forming a point.
Claim 8
Dependent Claim
41 words
A method as defined in claim 6, said aluminum wire having an end face, said pointed portion of said copper wire being forced into said aluminum wire through its end face in a direction along the length of said aluminum wire.
Claim 9
Dependent Claim
12 words
An electrically conductive joint made by the method defined in claim 1.
Claim 10
Dependent Claim
37 words
An electrically conductive termination device comprising a copper wire cold welded at one end to an aluminum wire by the method defined in claim 6, and terminal connecting means on the other end of said copper wire.
