Patent ID: 7066039

Claim:
A testing device, comprising: a component including an electrical conductor, where the component is composed at least partially of an electrically non-conductive material and includes an attachment eyelet which is composed of electrically non-conductive material; a contact element which is embedded in the non-conductive material of the attachment eyelet and which contact element includes electrically conductive contact cutting parts embedded in the electrically non-conductive material of the attachment eyelet, wherein the contact element forms an annular disk around a hole and a material of a predetermined thickness formed of plastic is present surrounding the contact element; a base body containing an electrical conductor; a mechanical attachment device containing a screw which can be screwed into the base body through the attachment eyelet, and an electrical connection between the respective conductors is made through the screw when the screw is tightened through the electrically conductive contact cutting parts; and a testing circuit for testing the electrical connection.
