ignition coil

The innovation relates to an ignition coil.

An ignition coil according to the innovation contains a hollow housing and an insulating cover which encloses the housing and is characterized in that the lid is molded around a conductive clip that engages with their Ends extending through the inner and outer surfaces of the lid.

The innovation will be explained in more detail below with reference to the drawings, in which:

In Pig. 1 and 2, an ignition coil is shown, which has a hollow housing 11, which at its open end by means an insulating cover 12 is closed. At the other end of the housing 11 away from the lid 12, an insulating support member IJ is provided and between A laminated iron core 14 is arranged on the cover 12 and the insulating part support part IJ. On one

primary and secondary windings of the ignition coil. The cover 12 has two conductive terminals 16, 17 on two opposite sides to a centrally arranged high-voltage terminal l8. One end of the primary winding and the secondary winding lor ignition coil is connected to terminal 16, while the other end of the primary winding is applied to terminal 17 ;. The other end of the secondary winding is over the core 14 with the high voltage clamp 18 connected. During operation, the terminal 17 is connected to a direct current source. The clamp 16 is grounded via a contact breaker and the high-voltage terminal 18 is in turn connected to the spark plugs an internal combustion engine applied via an ignition distributor.

The cover 12 is pressed out of a synthetic resin in such a way that the terminals 16, 17 are first inserted into a mold and the cover 12 is then pressed out around the terminals 16, 17. The clamps ΐβ, 17 are fixed in the cover in that either a shoulder 19 or a bore 21 is provided (Fig. J5 and 4) through which the synthetic resin flows. The terminals 16, 17 contain a plate part 22 which extends outwardly out of the cover and onto which a known base connection can be placed. Furthermore, the terminals 16, 17 have a hook part 2j5 ₅ which extends inwardly into the ignition coil and to which the lines from the windings of the ignition coil are connected in the manner described.

As in the Pig. 5 and 6 are the clamps 16, 17 also formed with a pear of plate coils.
