Abstract: A pair of confronting and spaced contact surfaces of a predetermined conductive material are electrically interconnected by a spring-type contact that is between the surfaces. The contact has an anchored end secured to one of the surfaces, an opposite free end, and a plurality of blades unitary with and extending between the ends and each having a bowed section engaging a respective contact surface. These bowed sections of the contact extend in opposite directions toward the contact surfaces and form contact points engageable with the respective contact surfaces. A coating on each of the contact points is of a material matched to the conductive material of the contact surfaces.

Abstract: The invention relates to a contact spring (1) which has lamellae (8, 9) in the direction of a respective contact area (2, 3), it being possible to bring the lamellae (8, 9) into contact with the contact areas (2, 3) by means of contact points (6, 7), wherein the invention provides that at least one of the contact points (6, 7) has a coating, with the respective material of the coating being matched to the material of the contact area (2, 3).

Abstract: The invention relates to a carrier (1) for holding an electronic device, in particular an antenna amplifier of a vehicle, having at least one printed circuit board (9), the electronic device being able to be attached to a vehicle component, in particular a vehicle window (12), by means of the carrier (1) which is composed of an electrically nonconductive material, there being provision according to the invention for the carrier (1) to be embodied in a planar fashion and to have latching means as well as spring means which interact therewith and have the purpose of securing the printed circuit board (9) to the carrier (1), as well as at least one recess for holding a contact element in order to make electrical contact with a contact face of the printed circuit board (9) by means of a corresponding contact face (13) on the vehicle component.

Abstract: A coupler for a coaxial plug and connectable with a cable, especially an antenna coupler with an outer conductive sleeve comprised entirely or partly of metal and formed by bending from a blank whose basic shape is produced by stamping or punching from steel metal.

Abstract: A plug for a coaxial connector and cable, especially an antenna plug, in which the outer conductive sleeve is formed entirely or partly of metal by punching, stamping, cutting or the like from sheet metal and is then bent into the sleeve shape, provided around an insulator and contact pin and held around that insulator by plastic deformation.
