Definitions

  • the invention relates to an arrangement with an ignition coil having an iron core projecting on both sides of the coil body and an ignition coil switching device.
  • An arrangement of ignition coils is known from DE-OS 27 20 065, in which the coil elements and the control elements of an electronic ignition system are arranged in a one-piece housing made of die-cast.
  • the internal structure of the die-cast housing is adapted to the shape of the elements mounted in it, which is why only elements with very specific dimensions can be inserted into the housing.
  • the ignition coil is also known to mount the ignition coil on the distributor, the coil housing being fastened either to the cap or to the housing of the distributor, but at least being made in one piece with one of the two.
  • an ignition coil switching device with the characterizing features of the main claim has the advantage that an all-round enclosed space can be formed in a simple manner by using a very simply constructed holder which is essentially of cross-sectional design the electrical connecting lines and the associated connections can be arranged protected against contact.
  • a heat-conducting connection between the cooling plate of the ignition coil switching device and the iron core of the ignition coil is created via the side walls of the holder. The heat generated can thus be optimally dissipated and radiated.
  • the upwardly open space of the holder is preferably closed with a protective cover serving as a contactor.
  • the protective cover can consist of an electrically insulating material.
  • the connecting lines between the ignition coil and the ignition coil switching device can be designed as stable busbars which are particularly short and simple in the case of directly opposite connection terminals.
  • Figure 2 is a side view of that shown in Figure 1
  • Figure 3 is a top view of the arrangement shown in Figure 1.
  • FIG. 1 the end face of a holder 1 and an ignition coil 2 can be seen.
  • the holder 1 encompasses the egg core 3, which is partially shown in FIG.
  • the holder 1 is shown in section in the lower area, so that there the bottom 4 is visible.
  • the bottom 4 connects its two side walls 5, 6 (FIG. 3), so that the holder 1 essentially forms a U-shaped part.
  • a cooling plate 9 is screwed, which is part of an ignition coil switching device 10, the components of which are arranged in the interior 11.
  • the connection between the side walls 5, 6 and the cooling plate 9 takes place via screws 12, 13.
  • the interior 11 is thus completely closed off from the cooling plate 9 in the region of the end face 8.
  • the top of the arrangement is covered by a protective cover 14, which serves as a contactor.
  • the interior 11 is thus closed on all sides, specifically by the holder 1 with its side walls 5, 6 and with its base 4, by the iron core 3, by the cooling plate 9 and by the protective cover 14.
  • FIG. 3 shows two busbars 15, which run from the ignition coil control device 10 to the connections 16 the ignition coil 2.
  • An ignition coil plug 17 and a three-ply connector plug 18 leading to the ignition coil switching device 10 protrude from the upper side for connecting corresponding lines.
  • the conventional holder 1 engages around the iron core 3 in the form of an angle 19, 20 and is connected to the iron core 3 by means of through rivets 21, 22. Good heat transfer between the iron core 3 and the cooling plate 9 is thus achieved via the holder 1 made of die-cast aluminum.

Abstract

Boîtier comportant une bobine d'allumage présentant un noyau en fer doux faisant saillie des deux côtés sur le corps de la bobine, et un appareil de connexion de bobine d'allumage, dans lequel, grâce à l'utilisation d'un support d'une construction très simple, dont la section est en forme générale de ''U'', un espace intérieur fermé de tous côtés peut être formé de manière simple, la plaque de refroidissement de l'appareil de connexion formant le prolongement du recouvrement. Cette construction permet, d'une part, que la chaleur formée soit évacuée de façon optimale et, d'autre part, que l'appareil de connexion, aussi bien que la bobine d'allumage, soient protégés.
