Abstract
A contact body is disclosed, comprising at least two contact sheets having opposing surfaces and a projection extending outward from one surface of each contact sheet, wherein the projection defines a depression on the opposite surface of the contact sheet, a projection of one contact sheet being disposed within a depression of an adjacent contact sheet to form a projection-depression coupling, and the projection-depression coupling being deformed to form a positive lock. A method and apparatus of connecting contact sheets to form a contact body are also disclosed, that provide for deforming projection-depression couplings formed in two or more interlocking sheets to form positive locks by which assemblies of sheets are formed. The apparatus includes crimping devices that crimp projection-depression couplings located in the interior area of the interlocked sheets and projection-depression couplings located adjacent the side edges of the interlocked sheets, again to form positive locks by which assemblies of sheets are formed.
