PCT No. PCT/DE91/00813 Sec. 371 Date Oct. 23, 1992 Sec. 102(e) Date Oct. 23, 1992 PCT Filed Oct. 17, 1991 PCT Pub. No. WO92/13354 PCT Pub. Date Aug. 6, 1992.The fastening arrangement for electrical connection to an ignition coil includes a housing; an epoxy resin circuit board in the housing and having a plurality of conductor paths electrically insulated from each other, each of which are provided with at least two ends having a bore hole for electrical connection to the primary windings; and a connection plug including elements for easily securing it to the housing and a plurality of electrical contacts extending from an exterior side of the plug and into the housing on an interior side. The housing is provided with a recess to accommodate the connection plug and a guide groove in the recess in which a projecting guide element of an outer peripheral flange of the connecting plug is pressed to fix the connection plug to the housing. The electrical contacts are electrically insulated from each other and each of them includes a pin on its interior end. The pins of the electrical contacts project through respective bore holes in the conductor paths and are soldered with the respective conductor paths so that the connection plug and the printed circuit board form a primary plug unit for making electrical connection to the ignition coil.
