Abstract
Abstract A terminal construction for a thermoelectric element. A thermally and electrically conductive cap is provided with a recess, against the bottom of which is welded woven wire screening. Powdered thermoelectric material is pressed into the recess, through the screening and against the bottom of the recess, interlocking mechanically with the mesh and forming a permanent thermal and electrical connection to the cap.
