ABSTRACT:
A wrist strap can be connected through the fabric of a cleanroom garment by means of an inexpensive, removable connector comprising two molded plastic parts that can be interconnected to entrap the fabric. Protruding from a reservoir in the first of the two plastic parts is an open tube of open-cell foam which is filled with an electrically conductive gel. The foam tube protrudes from the reservoir and, when the two plastic parts are interconnected, the foam tube is compressed and transmits a squeezing force to the conductive gel, thus forcing a portion of the conductive gel through the exposed open end of the foam tube into the entrapped fabric and against an electrode in the second of the two plastic parts. This completes an electrical connection between that electrode and an electrode in the first plastic part at the base of the reservoir. The conductive gel may also be carried in a collapsible cup which is biased to force the conductive gel through the fabric to complete the electrical connection.
