US Patent 7645962 Portable grounding mat with improved terminal

This invention relates to a portable grounding mat, and more particularly to a mat specifically designed to protect electrical workers by providing a zone of equi-potential. The mat has a flexible base to which is attached at least one conductive element laid out in a grid pattern. A novel terminal that electrically connects the mat to a power source has an inner core to provide an electrical load path and an outer casing to provide a mechanical load path, resulting in a superior mat design.
