Definitions
- the present invention relates to an ignition coil, in particular for an internal combustion engine of a motor vehicle, according to the preamble of claim 1.
- a coil is known from document EP-A-0 253 939.
- Such a coil generally comprises at least one magnetic assembly of the closed circuit type, each comprising a central magnetic core around which are coaxially arranged two coils of plastic material carrying the primary and secondary windings, this assembly being integrated in an overmolded housing.
- a magnetic flux return circuit which constitutes the metal frame thereof. Synthetic resin, poured inside the housing secures and electrically insulates between them the various elements constituting the ignition coil.
- the assembly of the primary assembly in the secondary assembly must be carried out precisely so that the spacings in all directions between primary and secondary are perfectly dimensioned.
- Another problem to be resolved is to keep the primary assembly in place in the secondary so that, when the resin is injected into the housing, the primary assembly retains its position relative to the secondary assembly.
- the present invention as defined in claim 1, solves these problems.
- FIG. 1 represents an exploded view of the various elements of an ignition coil 1 for an internal combustion engine of a motor vehicle.
- this is a coil enabling the 4 spark plugs corresponding to the 4 cylinders of the engine to be supplied.
- Each magnetic circuit is closed and has a primary winding 2 wound around a reel 3.
- a central magnetic core 4 of rectangular outline and generally composed of cut and laminated magnetic sheets is housed inside the reel 3.
- the secondary assembly S is held in lift on and around the primary assembly P.
- each of these terminals is intended to be conventionally connected, by an appropriate cable, to a spark plug associated with each cylinder of the engine.
- Each high-voltage terminal B1, B2, B3, B4 comprises a high-voltage pad 30 which is fixed by screwing in a connection plate 28, previously inserted in a groove 26 of the coil 5. On one end of this connecting plate 28, the end of the secondary winding is welded.
- the low-voltage connection is effected by a connection assembly consisting of a precut link bar 61 which is inserted into a connector 60.
- the primary P and secondary S assemblies being assembled one inside the other, the two magnetic circuits M1 and M2 thus formed are introduced into the housing 7 of a housing 8 made of insulating material.
- a magnetic flux return circuit 9 the general U shape of which can be seen, consisting of cut and laminated magnetic sheets, is incorporated by molding in the housing 8.
- the magnetic flux return circuits 9 constitute the metal frame of the housing 8.
- FIG. 3 showing the secondary assembly S which consists of the coil 5 made by molding plastic material having at each of its ends a flange 20,21 and over the entire outer periphery of the tubular means constituting the secondary coil 5, a plurality of discs 22 compartmentalizing said spool.
- Two wires, wound on the spool 5, constitute the secondary windings 6.
- the discs 22 make it possible to maintain the wires constituting the windings 6 stacked over a large thickness.
- the secondary winding 5 comprises a tubular housing 56 intended to receive the primary assembly P.
- each primary assembly P is shown ready to be assembled with the corresponding secondary assembly S by entering them in the direction indicated by the arrows F1, F2.
- Each primary coil 3 has two end flanges 40,41.
- the flange 40 on the flange 40 are provided in material complementary means comprising two bosses 50, 51 of generally rectangular shape, a lateral part 52 of which protrudes from each of the vertical walls of the flange 40.
- the walls of the flange 41 of the primary coil 3 cooperate with the walls of the housing 56, then pass through the redents 57 , 58 thanks to their elasticity, immobilizing in translation the primary assembly P.
