    • To eliminate welded or soldered connections between the fine or thin secondary wire (18, 18a) of an ignition coil and the high-voltage terminal plug, the high-voltage terminal arrangement includes a tubular stub (19) having a conical opening (29) therein, within which the end portion (18a) of the secondary wire can be placed, preferably in form of twisted-together loops (28), and the connection is effected by a screw machine part (30) in form of a conical plug, press-fitted within the conical opening, and making electrical connection with the twisted wire, while being retained securely within the stub (19). After insertion, the plug, the primary and secondary windings, and the core can all be molded or potted by being surrounded with a plastic injection molding or a potting compound. The twisted wire ends can be pre-tinned, and the surface of the plug smooth; or the surface of the plug can be knurled, stippled or ridged to bite through magnet wire insulation.
    • 为了消除点火线圈的精细或细二次线(18,18a)与高压端子插头之间的焊接或焊接连接,高压端子装置包括具有锥形开口(29)的管状短截线(19) 其中可以放置二次线的端部(18a),优选地以双绞线圈(28)的形式,并且该连接由锥形塞形式的螺旋机器部件(30)实现, 压配合在锥形开口内,并且与绞合线电连接,同时牢固地保持在短截线(19)内。 在插入之后,插头,初级和次级绕组以及芯子都可以通过塑料注射成型或灌封化合物包围来模制或灌封。 绞线末端可以预先镀锡,并且插头的表面光滑; 或者插头的表面可以滚花,刻点或脊状咬合通过电磁线绝缘。
