Abstract:
1. A testing apparatus for detecting a contact deficiency of an electrically conductive connection comprising a plurality of electrically conductive system elements having insulated and metallic components for conducting signals or energy, the testing apparatus comprising: a measuring chamber; a heat radiator; a thermal (image) acquisition unit; and a thermal (image) reproduction unit; wherein in the measuring chamber the system components of the electrically conductive connection are positioned, wherein the system components are connected to one another in an electrically conductive fashion; wherein the heat radiator is capable of being supplied with energy; wherein the transferred thermal radiation of the heat radiator can be emitted into the measuring chamber and the thermal radiation can be directed toward the region of the system elements, such that a thermal field of the insulated and the metallic system components of these connected system elements is generated, wherein the thermal (image) acquisition unit is adapted for optically capturing the generated thermal field emitted by the heated insulated and metallic system components of said connected system elements and for realizing a signal conversion into a thermal image of the connected system elements; wherein the thermal (image) reproduction unit is adapted for realizing a visual reproduction of the converted thermal image; and wherein the thermal (image) acquisition unit and the thermal (image) reproduction unit are connected in an information technological manner.
