Abstract
Abstract A method of connecting an electrical lead to an electrode is provided wherein the connection is mechanically tight and is protected from chemical attack. The electrical lead and a slug of electrically conductive material are compressed within a hole in the electrode to provide a tight mechanical connection. Insulating material is added to fill the remainder of the hole and a second insulating material is installed over the area of the connection to protect the area from chemical attack.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
An electrical connection between an electrical cable and an electrode comprising: an electrode, said electrode having an end having a hole drilled axially; an electrical cable, said electrical cable having insulation, said insulation being stripped from a portion of said electrical cable to form said electrical connection; an annular slug of an electrically conductive material, said annular slug being disposed about said stripped portion of said electrical cable and said stripped portion of said electrical cable and said annular slug being disposed within said hole within said electrode, said annular slug being compressed within said hole; a first insulating material filling said hole within said electrode and extending therefrom; and at least one layer of a second insulating material placed about the portion of said electrode enclosing said electrical connection to protect said electrode about said electrical connection from chemical attack.
Claim 2
Dependent Claim
141 words
An electrical connection between an electrical cable and an electrode comprising: an electrode, said electrode having an end having a hole drilled axially; an electrical cable, said electrical cable having insulation, said insulation being stripped from a portion of said electrical cable to form said electrical connection; an annular slug of an electrically conductive material, said annular slug being disposed about said stripped portion of said electrical cable and said stripped portion of said electrical cable and said annular slug being disposed within said hole within said electrode, said annular slug being compressed within said hole; a first insulating material filling said hole within said electrode and extending therefrom; and at least one layer of a second insulating material placed about the portion of said electrode enclosing said electrical connection to protect said electrode about said electrical connection from chemical attack.
Claim 3
Dependent Claim
34 words
The electrical connection of claim 1, wherein said hole in said electrode has an innermost portion, said innermost portion of said hole being threaded whereby the mechanical strength of said electrical connection is increased.
Claim 4
Dependent Claim
15 words
