Description
La présente invention concerne une bobine d'allumage, en particulier pour moteur à combustion interne de véhicule automobile.The present invention relates to an ignition coil, in particular for an internal combustion engine of a motor vehicle.
De manière connue en soi, le secondaire d'une telle bobine produit une tension très élevée permettant d'engendrer un arc électrique aux électrodes des bougies d'allumage, enflammant ainsi le mélange comburant contenu dans les cylindres du bloc moteur.In a manner known per se, the secondary of such a coil produces a very high voltage making it possible to generate an electric arc at the electrodes of the spark plugs, thus igniting the oxidizing mixture contained in the cylinders of the engine block.
Habituellement, une seule bobine commande l'ensemble des bougies d'allumage par l'intermédiaire, par exemple, d'un distributeur mécanique, généralement du type à doigt tournant.Usually, a single coil controls all of the spark plugs via, for example, a mechanical distributor, generally of the rotating finger type.
Une telle installation présente l'inconvénient de nécessiter un faisceau de câbles haute-tension permettant de relier d'une part, le secondaire de la bobine d'allumage au distributeur, d'autre part, le distributeur à chacune des bougies d'allumage.Such an installation has the disadvantage of requiring a bundle of high-voltage cables making it possible to connect on the one hand, the secondary of the ignition coil to the distributor, on the other hand, the distributor to each of the spark plugs.
En dehors du coût d'un tel faisceau, celui-ci est l'objet de fuites électriques générant des ondes radioélectriques parasites qui peuvent être acceptables avec l'utilisation d'un distributeur mécanique mais qui perturbent de manière importante l'ensemble du système d'allumage lorsque ce dernier est réalisé à l'aide de modules électroniques.Apart from the cost of such a beam, it is the subject of electrical leaks generating parasitic radio waves which may be acceptable with the use of a mechanical distributor but which significantly disturb the entire system d ignition when the latter is carried out using electronic modules.
De manière à supprimer ces inconvénients, on a déjà proposé d'associer individuellement à chaque bougie d'allumage une bobine.In order to eliminate these drawbacks, it has already been proposed to associate individually with each spark plug a coil.
La présente invention se rapporte plus particulièrement à une telle bobine dite monocylindre qui comporte un ensemble magnétique à circuit fermé, comprenant un noyau magnétique central autour duquel sont disposés coaxialement deux bobineaux en matière plastique portant les enroulements primaire et secondaire, cet ensemble étant intégré dans un boîtier surmoulé en matière plastique. De la résine synthétique, coulée à l'intérieur du boîtier solidarise et isole électriquement entre eux les différents éléments constituants la bobine d 'allumage.The present invention relates more particularly to such a so-called single-cylinder coil which comprises a closed circuit magnetic assembly, comprising a central magnetic core around which are coaxially arranged two plastic coils carrying the primary and secondary windings, this assembly being integrated in a molded plastic housing. Synthetic resin, poured inside the case, secures and electrically insulates between them the different components of the ignition coil.
L'un des problèmes à résoudre sur une bobine d'allumage de ce type est la réalisation de la connectique haute-tension qui permet la liaison entre l'extrémité du bobinage secondaire et la bougie d'allumage correspondante et notamment l'organe de sortie haute-tension qui se trouve en contact direct avec la bougie d'allumage à laquelle est associée la bobine.One of the problems to be solved on an ignition coil of this type is the realization of the high-voltage connection which allows the connection between the end of the secondary winding and the corresponding spark plug and in particular the output member. high voltage which is in direct contact with the spark plug with which the coil is associated.
Ce problème est partiellement résolu par le document GB-A-2 199 193 qui décrit une bobine conforme au préambule de la revendication 1.This problem is partially solved by document GB-A-2 199 193 which describes a coil conforming to the preamble of claim 1.
Ce document ne décrit pas toutefois de moyens rationnels permettant d'assurer le positionnement de l'ensemble de liaison haute-tension dans le boîtier et la fixation du guide haute-tension dans la potence.This document does not however describe rational means for ensuring the positioning of the high-voltage connection assembly in the housing and the fixing of the high-voltage guide in the bracket.

Cet insert 30 comprend une embase 31 sur l'une des faces de laquelle est ménagé un bossage 32 au centre duquel est agencée une fente 33. L'embase 31, le bossage 32 et la fente 33 sont de forme générale rectangulaire.This
L'embase 31 se prolonge, d'une part, par une patte 34 dont l'extrémité 35 est chanfreinée et présente une section de forme générale trapézoïdale, d'autre part, par une languette 36 dont l'extrémité 3 est pliée à angle droit et se situe sur la face opposée de l'embase 31 par rapport à la patte 34.The

Les figures 10 et 11 illustrent une telle bobine constituée notamment d'un boîtier 50 surmoulé en plastique et un connecteur 51 permettant l'alimentation basse-tension de la bobine.Figures 10 and 11 illustrate such a coil consisting in particular of a
Le circuit magnétique est fermé et comporte un enroulement primaire 52, bobiné autour d'un bobineau 53. Un noyau magnétique 54 de section rectangulaire et composé généralement de tôles magnétiques découpées et feuilletées est logé à l'intérieur du bobineau 53.The magnetic circuit is closed and has a
Autour de cet ensemble, coaxialement au bobineau primaire 53, est disposé un bobineau secondaire 55 autour duquel est bobiné un enroulement secondaire 56.Around this assembly, coaxial with the

L'insert haute-tension 30, décrit plus haut, est introduit par l'extrémité 35 de sa patte 34 dans une fente prévue à cet effet dans le bobineau secondaire 55. Sur l'extrémité 37 de la languette 36 de l'insert 30 on vient souder l'extrémité du bobinage secondaire 56.The high-

A cet effet, aux quatre coins du rectangle ainsi constitué, sur la face supérieure 58, sont ménagées 4 fraisures 59a, 59b, 59c, 59d au centre desquelles sont prévus des trous 60a, 60b, 60c, 60d traversant le boîtier 50 et le circuit magnétique de retour de flux 59 desdites fraisures sont destinées à recevoir les vis de fixation (non représentées) de l'ensemble de la bobine.For this purpose, at the four corners of the rectangle thus formed, on the
Avant coulage d'une résine synthétique à l'intérieur du boîtier pour immobiliser et isoler les différents constituants, on réalise l'ensemble de liaison haute-tension.Before pouring a synthetic resin inside the housing to immobilize and isolate the various constituents, the high-voltage connection assembly is produced.
Suivant l'invention, cet ensemble de liaison haute-tension est constitué d'un ressort 61 qui est introduit dans le guide haute-tension 25 jusqu'à ce qu'il vienne en butée contre sa languette 27 (figure 4).According to the invention, this high-voltage connection assembly consists of a
Ce ressort 61 venant en contact direct avec la bougie d'allumage associée à la bobine assure donc la transmission de la haute-tension, et constitue l'organe de sortie haute-tension.This
Le guide haute-tension 25 équipé du ressort 61 est introduit dans le logement 3 de la potence haute-tension 1 et est fixé dans celle-ci par encliquetage de la patte 27 du guide 25 dans la fente 20,21 (figures 2 et 3) du débouché 14 de la potence 1.The high-
Cet ensemble de liaison haute-tension ainsi réalisé est positionné dans le boîtier sur le bobineau secondaire 55 déjà mis en place.This high-voltage connection assembly thus produced is positioned in the housing on the secondary winding 55 already installed.
Ce positionnement est assuré, d'une part, par pénétration des pions 12 et 13 de la barrette 7 de la potence 1 dans des logements correspondants prévus à cet effet dans le bobineau secondaire 55, d'autre part, par pénétration de l'extrémité amincie 29 de la patte 28 du guide 25 dans la fente 33 de l'insert haute-tension 30.This positioning is ensured, on the one hand, by penetration of the
L'ensemble haute-tension étant ainsi positionné dans le logement 57 du boîtier 50 on coule de la résine synthétique qui le remplit jusqu'à un niveau N proche de celui de la face 62 du boîtier 50.The high-voltage assembly is thus positioned in the
On s'arrange pour que ce niveau N soit toujours supérieur au niveau N′ correspondant à l'extrémité du ressort 61 dans le guide haute-tension 25.It is arranged so that this level N is always greater than the level N ′ corresponding to the end of the
Suivant l'invention, le durcissement de la résine immobilise tous les constituants à l'intérieur du boîtier 50 et en particulier le ressort 61.According to the invention, the hardening of the resin immobilizes all the constituents inside the
On a ainsi réalisé notamment avec le ressort 61 une liaison haute-tension présentant de nombreux avantages : plus de pièce d'usure, résistance aux vibrations, fixation aisée.A high-voltage connection has thus been produced in particular with the
On remarquera que, lorsque la bobine est fixée sur la culasse du moteur, la face 62 du boîtier 50 présentant la résine se trouve en bas comme illustré sur la figure 11 et se trouve donc naturellement protégée contre les agressions.It will be noted that, when the coil is fixed on the cylinder head of the engine, the
