Abstract From the Canadian patent

An improved form of battery cable is produced through the use of a battery terminal member which has a copper tube projecting from the end thereof. The multistrand electrically conductive cable is cut to the desired length, the end is stripped and inserted into the copper tube and the copper tube is crimped into a diamond-shaped crimp to form a substantially solid mass of the cable strands therein. Then, a plastic sleeve is heat shrunk over the copper tube and a portion of the cable sheath to form a corrosion-free connection.
