Abstract:
A flat resistor,comprising the following separate generally flat components assembled into a stack in the following order:a first flat metal outer plate having a plurality of assembly tabs bent transversely therefrom,a first thin flat outer electrical insulator having alignment slots therein for receiving said tabs with an alignment fit,a first thin flat sheet metal electrical resistance element separate from said first insulator and having oversized slots therein for receiving said tabs with a clearance fit for obviating any engagement between said tabs and said first resistance element,a first thin flat inner electrical insulator separate from said first electrical resistance element and having alignment slots therein for receiving said tabs with an alignment fit,a metal midplate having oversize slots therein for receiving said tabs with a clearance fit,a second thin flat inner insulator having alignment slots therein for receiving said tabs with an alignment fit,a second thin flat sheet metal resistance element separate from said second inner insulator and having oversize slots therein for receiving said tabs with a clearance fit for obviating any engagement between said tabs and said second resistance element,a second thin flat outer insulator separate from said second electrical resistance element and having alignment slots therein for receiving said tabs with an alignment fit,and a second metal outer plate having alignment slots therein for receiving said tabs with an alignment fit,said tabs on said first outer plate being bent into secure engagement with said second outer plate for compressing and retaining the stack of said components.
