<p>The invention relates to an electrical contact stud (1), a cap nut (12) made of plastics material, an electrical contact system for fastening an electrical contact and a method for fastening an electrical contact to a workpiece (11) to be painted. The invention is characterised in that a cap nut (12), which can be economically produced, made of plastics material, which does not necessarily have to be electrically conducting, is used for fastening an electrical contact shoe (21). As a plastics material nut can be designed as self-securing, the required maximum torques for producing the contact are relatively small, in particular, for example 8 Nm, whereby fastening an electrical contact is made possible even with thin sheets of metal with sheet metal thicknesses of less than 0.6 mm without deformations. The cap nut (12) made of plastics material serves in a first step as a seal against the penetration of paint into the electrical contact region and in a second step for fastening a contact shoe (21).</p> |
