  • Multiple penetration aluminum connector and method
    Patent number: 3973824
    Abstract: An aluminum sleeve connector is applied to an aluminum conductor using multiple deep penetrations of the connector wall into the conductor. The penetrations are sufficient to at least fill the void volume between the connector and conductor in the transverse cross-section in which they lie. Each penetration causes plastic flow in the extruded material of the connector and in the conductor at their interface to minimize spring back and causes shearing at the interface to remove any oxide or other insulative coating.
