Definitions
- the present invention relates to an ignition coil with a coil former, which has a wire winding.
- Such ignition coils are well known in engine electronics, in particular for the automotive industry. Problems always arise from contacting the beginning and end of the wire winding, in particular, so that the primary connection in the engine compartment itself can be simplified later.
- connection device is coupled to the coil body according to the characterizing part of claim 1, the connection device itself having connection elements for the beginning and end of the wire winding. If this ignition coil with connection device is later installed in an engine, a simple contact can be made via a plug.
- the connecting elements preferably consist of contact springs which have a clamping piece for the beginning and end of the wire winding. As a rule, the contact springs will consist of a material that is customary for power conduction. After the winding has been produced, the beginning and end of the winding wire and possibly also a ground wire are inserted into the clamping pieces, these are clamped and welded. This defines the start and end of the wire so that the winding can no longer change. In addition, a low-electrical contact is produced in this way. The contact springs pull through the connection device and end as connector lugs in a connector opening.
- connection device is coupled to the coil former in a simple manner.
- a detent spring is molded onto the coil body to fix the connection device.
- this detent spring is T-shaped, it runs downward away from the coil former, then has an offset and engages under the connecting device in the position of use. It is determined by the crossbar of the T, which in the end position engages behind a locking edge on the connection device.
- a latching cam can also be formed on the coil body, which engages behind a corresponding latching pawl on the connection device in the position of use.
- a guide channel delimited by two guide strips is provided for guiding the locking cam.
- connection device is guided opposite the coil body between a strip and a lower surface of the coil body, the strip and lower surface being one enter into a positive connection with a rail on the connection device.
- the rail and lower surface should be wedge-shaped, the wedges having opposing rising surfaces.
- FIG. 1 shows a longitudinal section through an ignition coil with a connecting device and the inventive contacting of the primary connection and the primary winding;
- FIG. 2 shows a front view of the ignition coil according to FIG. 1;
- FIG. 3 shows a partially shown bottom view of the ignition coil with connection device and contact according to FIG. 1;
- FIG. 4 shows a longitudinal section through an ignition coil housing according to the invention
- FIG. 5 shows a bottom view of the ignition coil housing corresponding to FIG. 4;
- FIG. 6 shows a side view of a connection device according to the invention
- FIG. 7 shows a top view of the connection device according to FIG. 6.
- - k - Figure 8 is a plan view of another embodiment of a connection device;
- FIG. 9 shows a longitudinal section through an ignition coil with a connection device corresponding to FIG. 8.
- an ignition coil 1 is coupled to a connection device 2.
- the ignition coil 1 has a coil body 3 which is covered with a winding 4.
- a detent spring 5 protrudes downward from the coil body 3 and serves to hold the connection device 2.
- the detent spring 5 is T-shaped, the stem of the T being connected to the bobbin 3, but then being bent so that the crossbar 6 of the T again runs approximately parallel to the underside 7 of the bobbin 3.
- a foot 8 of the detent spring 5 also strikes a bar 9, which rests in the use position according to Figure 1 of a wedge-shaped rail 10 of the connection device 2.
- This bar 9 is also assigned a wedge-shaped lower surface 11 on the coil body 3, which together with the bar
- connection device 9 forms a form-fitting holder of the rail 10.
- connection device 2 is guided to the catch spring 5, a catch edge 12 (see in particular FIG. 3) engaging behind the crossbar 6 in the end position. In this way, the connection device 2 is fixed to the coil body 3.
- Two contact springs 13 and 14 lead out of the connecting device on both sides. At the end, these have contact springs 13 and 14, a clamping piece 15, into which, in the position of use of the connecting device 2 according to FIGS. 1 to 3, a beginning 16 and an end 17 of the winding wire are inserted. In the present embodiment, a ground wire is still in the clamping piece 15 of the contact spring 14
- connection device 2 is shown in greater detail in FIGS. 6 and 7.
- connection device 2 has handles 20 on the side. Furthermore, it can be seen that the contact springs 13 and 14 are guided next to one another in the housing 19 (shown in dashed lines). They end with connector lugs in a connector opening 21 (see FIG. 2). This ensures reliable contacting.
- connection device 2a is likewise inserted with a wedge-shaped rails 10 between a corresponding strip and lower surface (shown separately in this exemplary embodiment). Furthermore, the spool body 2a is formed with a locking cam 23 which, when the connecting device 2a is inserted, passes through a guide channel 24 and then engages behind a locking pawl 25.
- the guide channel 24 is laterally delimited by two guide strips 26 and 27.
- a separate clamping piece 15a is also provided in the center for a ground wire, this clamping piece 15a in turn having its own
- Plug lug 22a is assigned in the plug opening 21.
