Abstract: A high frequency plasma ignition device for the ignition of a fuel/air mixture in a combustion chamber of an internal combustion engine, having a series resonant circuit of an electric inductor and an electric capacitor connected in series, and a high frequency generator with a first electrical terminal and a second electrical terminal for the resonant excitation of the series resonant circuit, a first electrical contact point being provided in which one end of the capacitor and one end of the inductor are connected to one another electrically. An electrical connecting device connects the high-frequency generator to the inductor and to the capacitor such that an output signal of the high-frequency generator is applied to the series resonant circuit. An electric voltage is applied across the capacitor for igniting a plasma between free ends of a first and second electrode. An electric voltage is further applied to maintain the plasma after ignition.

Abstract: A contact spring having a free contact end for producing an electrical contact between the free contact end and a contact surface, the contact spring formed from N contact spring metal sheets and N?1 spacer elements. The contact spring metal sheets are fixed in a clamping region with a spacer element between two adjacent contact spring metal sheets, are at a distance from each other in a spring region around the thickness of the spacer elements, extend parallel to each other up to the free contact end in a freely elastic manner, and end in a common plane on the free contact end. In the spring region, the contact spring metal sheets have at least one bend with a pre-determined angle between the longitudinal axis of the contact spring metal sheets before the bend and the longitudinal axis of the contact spring metal sheets after the bend.

Abstract: The invention relates to a coaxial plug for connecting to a high-frequency transmission line. The housing of the coaxial plug has two slits arranged opposite each other, extending from the plug-side end in the axial direction, and both arranged and designed to form an axial abutment for receiving a BNC pin. A latching fork is arranged on the housing with two latching prongs tangentially overlapping an axial slit of the housing between the abutment and the plug-side end. Each BNC pin is held between a latching prong and an abutment of the axial slit, creating a locked connection between the coaxial plug and the BNC coaxial socket. The latching fork is pivotably arranged between a locking position in which the latching prongs tangentially overlap the axial slits, and a clearing position in which the latching prongs clear the axial slits over the entire length thereof.
