Abstract:
1. A low profile double impedance bond for connection to opposite sides of a pair of insulated breaks on a pair of rails, the impedance bond comprising a rectangular enclosure configured for placement intermediate the pair of rails and attachable to ties supporting the rails, the enclosure including a bottom plate portion, the impedance bond further comprising a first coil assembly and a second coil assembly, each of the coil assemblies mounted to the bottom plate portion, each of the coil assemblies having a stacked UI core with a first coil and a second coil wound around the stacked UI core, each coil having a winding of copper sheet material with two ends and a pair of terminals straps soldered to the ends of the copper sheet material, each of the terminal straps having a rectangular cross-section and having a solder portion and a terminal connection portion, one of the terminal straps configured as a rail connection terminal strap and extending out of the end of the enclosure and the other configured as a centertap connection terminal strap and extending in an inboard direction for electrical connection with the other centertap connection terminal straps, the rail connection terminal strap extending out of the enclosure having its solder portion positioned proximate the core and having the winding of the copper sheet material extending over said terminal strap thereby providing structural support.
