Abstract
The invention discloses an arrangement for mechanically and electrically contacting a glow wire of a thermal radiation source, comprising a glow wire made of refractory metal having at least one flat connection surface to be contacted, a contact surface on which the glow wire is contacted, and a contacting means which connects the glow wire to the contact surface. The invention also relates to a method for producing the contact according to the invention. The problem addressed by the invention, of providing a reliable and enduringly stable mechanical and electrical contact of glow wires made of refractory metals, is solved in that the flat connection surface has at least two perforations and/or at a circumferential edge of the connection surface of the glow wire at least two recesses are formed, wherein the contacting means is integrally connected to the contact surface at the location of the perforations and/or recesses and forms both an electrical and a mechanical connection to the glow wire at the location of the perforations and/or recesses by means of a flange-like design of the contacting means above the connection surface of the glow wire.
