The present invention relates to a method of securing connection tags to electrical conductors in thermal foils and the like in which a contact plate is riveted in place near a hole passing through plastic layers (1, 2) and a metal part (3). In this method the contact plate (9) is riveted in place near a hole (4) passing through the plastic layers and a metal foil (3) arranged adjacent to the layers (1, 2), by means of a hollow rivet (6) which is passed through the hole. On the opposite side of the hole the rivet has been bent around an upset (8) at the lower edge of the hole, the hole (4) having been made with the aid of a mandrel (5), suitably hot and at least partly conical in shape, so that the upper edge of the hole is flanged to a recessed sealing surface for the rivet (6), the central part has been formed to an exposed cylindrical metal contact surface (7) against the rivet (6), and the lower side to a sealing upset (8), preferably reinforced at the edge, increasing the contact pressure and hermetically sealing the area around the contact surface. |
