The invention relates to an interrupter lever for ignition systems for operating internal combustion engines with a break contact on one side and a bushing on the other End, while a deflector and a breaker spring riveted to its central portion are, at the free end of a connecting cable and a post insulator are attached.

Such interrupter levers can be pivoted in the distributor housing to adjust the ignition point Interrupter determines which one with the primary current feedthrough through the distributor housing connected by a flexible cable that carries the primary current of the ignition coil via the breaker spring forwards to the breaker lever and to the breaker contact attached to it. To the Connection of the cable to the breaker spring and the housing bushing were previously two uses soldered cable lugs at the cable ends. On the spring there was another one with the cable lug Post insulator made of insulating disks riveted to isolate the spring opposite an abutment for the spring bent out of the breaker plate was used. This made the Cable connection to the spring is relatively complicated and expensive.

This connection to the interrupter spring is significantly simplified if, according to the Invention the connection cable by a hollow rivet in a known manner with the interrupter spring directly electrically connected and the post insulator made of plastic through Syringes is attached and encloses the junction. Appropriately, it essentially has the Form of a flat disc, in the middle of which the tubular rivet is located and from which the connecting cable and the Interrupter springs are led out radially and one side of which rests on the interrupter spring, while the other side has a cylindrical support extension which is coaxial with the washer and the tubular rivet having.

In the drawing, an embodiment of the subject matter of the invention is shown, namely in

F i g. 1 an interrupter spring with connection cable,

F i g. 2 the same spring in a longitudinal section through the connection point on an enlarged scale and in

F i g. 3 shows a complete breaker device on a breaker plate in the plan view of FIG above.

An interrupter spring is denoted by 10. At one end a connection cable 11 is attached. A hollow rivet 12 (FIG. 2), the

is inserted through a hole in the interrupter spring 10 and, when riveting, connects the cable core 11 ' to the interrupter spring 10 in an inseparable and electrically conductive manner. The rivet head of the hollow rivet is arched over the cable core in such a way that it is secured against deflection. A post insulator 13, which surrounds the connection point, is injection-molded from thermoplastic material. It is essentially in the form of a flat disc with the tubular rivet in the center and from which the connecting cable and the interrupter spring are led out radially and one side of which rests on the interrupter spring, while the other side is cylindrical and coaxial with the disc and the tubular rivet Approach 14 has.

In Fig. 3, a breaker plate is designated by 25. A plate 15 is fastened to it with a bent-up support 15 'for a fixed breaker contact 16 and a bearing pin 17 for a pivotable breaker lever 18, at the free end of which a breaker contact 19 is fastened, while in the middle section of the lever a deflector 20 and the breaker spring 10 are riveted. At one end of the interrupter spring 10 is corresponding to F i g. 1 and 2, the connecting cable 11 is attached, which is connected to a cable lug 23 in an electrically conductive manner. The support insulator 13 is used for insulation, which rests on an abutment 15 ″ bent at right angles from the contact carrier 15 and engages with the projection 14 in a hole in the abutment isolated.
