Description

La présente invention concerne les connecteurs électriques et, plus particulièrement, un connecteur antiparasité pour moteur électrique par exemple du type de ceux utilisés à bord des véhicules automobiles terrestres, et un procédé de fabrication d'un tel connecteur.The present invention relates to electrical connectors and, more particularly, a suppressor connector for an electric motor, for example of the type used on board land motor vehicles, and a method of manufacturing such a connector.

Comme on le sait, les moteurs électriques à courant continu à collecteur et balais sont générateurs de parasites dans des gammes de fréquences et avec des intensités qui perturbent la réception des émissions radioélectriques captées par les récepteurs radiophoniques qui équipent habituellement les véhicules automobiles terrestres. Classiquement, pour filtrer ces parasites, on utilise des circuits électriques constitués de self-inductances et de condensateurs, dont on équipe les moteurs électriques et qui sont très souvent montés sur la plaque porte-balais du moteur.As is known, direct current electric motors with collector and brushes generate parasites in frequency ranges and with intensities which disturb the reception of radioelectric emissions received by the radio receivers which are usually fitted to land motor vehicles. Conventionally, to filter these parasites, electrical circuits are used which consist of self-inductors and capacitors, with which the electric motors are fitted and which are very often mounted on the brush holder plate of the motor.

Les composants électroniques utilisés et leur localisation font qu'ils sont encombrants et gênants et que de la sorte ils nuisent à la réduction de l'encombrement général des moteurs et grèvent le coût de leur fabrication.The electronic components used and their location mean that they are bulky and annoying and that in this way they harm the reduction in the overall dimensions of the motors and increase the cost of their manufacture.

EP-A-0 363 724 décrit un connecteur antiparasité pour moteur électrique du type comprenant notamment un corps électriquement isolant dont la paroi extérieure est pourvue de passages pour des broches conductrices destinées à assurer une jonction électrique, ce corps comprenant une chambre intérieure qui est destinée à recevoir au moins un composant électronique dans laquelle pénètre au moins partiellement une partie interne des broches, au moins un orifice pour le passage d'un câble électrique destiné à assurer la jonction électrique avec la partie interne des broches, ces broches se présentant avec deux branches parallèles disposées relativement au corps de manière à avoir cette partie interne faite seulement d'une partie des branches et une partie externe faite du reste des branches, ce corps étant surmoulé sur la partie interne des broches après raccordement électrique du composant électronique destiné à occuper la chambre intérieure et du câble aux branches.EP-A-0 363 724 describes a suppressor connector for an electric motor of the type comprising in particular an electrically insulating body, the outer wall of which is provided with passages for conductive pins intended to provide an electrical connection, this body comprising an inner chamber which is intended receiving at least one electronic component into which at least partially penetrates an internal part of the pins, at least one orifice for the passage of an electric cable intended to ensure the electrical junction with the internal part of the pins, these pins being with two parallel branches arranged relative to the body so as to have this internal part made only of a part of the branches and an external part made of the rest of the branches, this body being overmolded on the internal part of the pins after electrical connection of the electronic component intended to occupy the interior chamber and the cable to the branches.

Le but de l'invention est de remédier aux inconvénients exposés ci-dessus à l'aide d'un connecteur perfectionné auquel sont incorporés des composants électroniques d'un circuit de filtrage des parasites engendrés par le collecteur et les balais d'un moteur électrique à courant continu.The object of the invention is to remedy the drawbacks exposed above using an improved connector which incorporates electronic components of a circuit for filtering parasites generated by the collector and the brushes of an electric motor. direct current.

A cet effet, l'invention a pour objet un connecteur antiparasité pour moteur électrique, du type précité, caractérisé en ce que le corps comprend au moins un logement qui est destiné à recevoir un autre composant électronique et qui débouche d'une part à l'aplomb de la partie interne de l'une des broches et d'autre part sur la paroi extérieure du corps, et en ce que le corps est surmoulé sur la partie interne des broches avant insertion du composant électronique dans le logement.To this end, the invention relates to a suppressor connector for an electric motor, of the aforementioned type, characterized in that the body comprises at least one housing which is intended to receive another electronic component and which opens on the one hand to the plumb of the internal part of one of the pins and on the other hand on the external wall of the body, and in that the body is overmolded on the internal part of the pins before insertion of the electronic component in the housing.

L'invention a aussi pour objet un procédé pour la fabrication d'un connecteur antiparasité pour moteur électrique comprenant notamment un corps électriquement isolant dont la paroi extérieure est pourvue de passages pour des broches métalliques de préférence plates destinées à assurer une jonction électrique, du type indiqué auparavant. Ce procédé est remarquable en ce qu'on découpe dans une planche métallique des broches qui se présentent à la manière d'un H avec deux branches parallèles reliées par un pont transversal frangible sécable, on raccorde électriquement à une même partie de ces deux branches parallèles un composant électronique et un câble électrique, on surmoule sur cette partie des deux branches parallèles destinées à former une partie interne des broches un corps électriquement isolant qui forme une chambre où est logé ce composant électronique et un orifice pour ce câble et qui emprisonne cette partie interne en laissant apparents le reste des branches et le pont formant ensemble une partie externe et qui ménage au moins un logement qui débouche d'une part à l'aplomb de la partie interne de l'une des branches et d'autre part sur la paroi extérieure du corps, on insère un autre composant électronique dans le logement en assurant le raccordement électrique à l'une de ces branches et on sépare le pont du reste des branches apparents, ces opérations d'insertion et de séparation pouvant être simultanées ou permutées.The subject of the invention is also a method for manufacturing a suppressor connector for an electric motor, comprising in particular an electrically insulating body, the outer wall of which is provided with passages for preferably flat metal pins intended to provide an electrical junction, of the type indicated before. This process is remarkable in that one cuts out of a metal board pins which are presented in the manner of an H with two parallel branches connected by a frangible frangible transverse bridge, one electrically connects to the same part of these two parallel branches an electronic component and an electric cable, one overmoulds on this part of the two parallel branches intended to form an internal part of the pins an electrically insulating body which forms a chamber where this electronic component is housed and an orifice for this cable and which traps this internal part leaving visible the rest of the branches and the bridge together forming an external part and which provides at least one housing which opens on the one hand directly above the internal part of one of the branches and on the other hand, on the external wall of the body, another electronic component is inserted into the housing, ensuring the electrical connection to one of these branches and the bridge is separated from the rest of the visible branches, these insertion and separation operations being able to be simultaneous or swapped.

La fabrication des connecteurs électriques et, en particulier, de ceux qui sont associés à des moteurs électriques à courant continu du type de ceux utilisés à bord des véhicules automobiles terrestres étant bien connus dans la technique, on ne décrira dans ce qui suit que ce qui concerne directement ou indirectement l'invention. Pour le surplus, l'Homme du Métier du secteur technique considéré puisera dans les solutions classiques courantes à sa disposition pour faire face aux problèmes particuliers auxquels il est confronté.The manufacture of electrical connectors and, in particular, those associated with direct current electric motors of the type used on board land motor vehicles being well known in the art, only what relates directly or indirectly to the invention will be described in the following. For the rest, the skilled person in the technical sector considered will draw on the current conventional solutions at his disposal to deal with the particular problems with which he is confronted.

Dans ce qui suit, un même numéro de référence identifie toujours un même élément homologue quel que soit le mode de réalisation ou sa variante d'exécution.In what follows, the same reference number always identifies the same homologous element whatever the embodiment or its variant of execution.

Pour la commodité de l'exposé, on décrira successivement chacun des constituants d'un connecteur antiparasité selon l'invention avant d'en exposer la fabrication et au besoin la mise en oeuvre.For the convenience of the description, each of the components of a suppressor connector according to the invention will be described successively before setting out the manufacture and, if necessary, the implementation.

Comme on le voit en examinant en particulier les Figures 1, 2 et 3 du dessin, un connecteur antiparasité pour moteur électrique selon l'invention comprend, essentiellement, un corps 10 et des broches 20.As can be seen by examining in particular FIGS. 1, 2 and 3 of the drawing, a suppressor connector for an electric motor according to the invention essentially comprises a body 10 and pins 20.

Un tel connecteur est destiné à être raccordé électriquement à un câble conducteur 30 afin d'être utilisé sur une plaque porte-balais 40 d'un moteur électrique à courant continu de tout type courant classique, par exemple du genre de ceux montés à bord des véhicules automobiles terrestres pour entraîner, par exemple, des groupes motoventilateurs ou des lève-vitres.Such a connector is intended to be electrically connected to a conductive cable 30 in order to be used on a brush holder plate 40 of a direct current electric motor of any conventional current type, for example of the type of those mounted on board land motor vehicles for driving, for example, fan units or window regulators.

Le corps 10, fait en un matériau électriquement isolant approprié, est délimité par une paroi 100 extérieure. Cette paroi extérieure 100 est définie par deux faces 101 opposées, deux flancs 102 opposés et deux côtés 103 opposés.The body 10, made of a suitable electrically insulating material, is delimited by an outer wall 100. This outer wall 100 is defined by two opposite faces 101, two opposite sides 102 and two opposite sides 103.

De préférence, le corps 10 se présente à la manière d'un arc d'anneau dont les deux côtés opposés 103 sont courbes au moins partiellement, l'un convexe et l'autre concave. Comme cela est illustré sur le dessin, le côté 103 concave est pourvu de préférence d'un méplat 1030.Preferably, the body 10 is in the form of a ring arc, the two opposite sides 103 of which are at least partially curved, one convex and the other concave. As illustrated in the drawing, the concave side 103 is preferably provided with a flat 1030.

Comme on le voit sur le dessin, dans le corps 10 sont ménagés des passages 11 destinés à recevoir les broches 20, une chambre 12 intérieure destinée à recevoir au moins un composant électronique d'un circuit d'antiparasitage de tout type classique approprié tel que, par exemple, une self inductance 120, ainsi qu'au moins un logement 13 qui débouche, d'une part à l'aplomb de la partie interne de l'une des broches 20, comme on le comprendra par la suite, et, d'autre part sur la paroi extérieure 100 du corps 10. Chaque logement 13 est destiné à recevoir un autre composant électronique du circuit d'antiparasitage tel que par exemple un condensateur 130, comme on le comprendra par la suite. Le corps 10 présente aussi au moins un orifice 14 pour la traversée du câble électrique 30.As can be seen in the drawing, in the body 10 are formed passages 11 intended to receive the pins 20, an interior chamber 12 intended to receive at least one electronic component of a suppressor circuit of any suitable conventional type such as , for example, a self-inductance 120, as well as at least one housing 13 which opens, on the one hand directly above the internal part of one of the pins 20, as will be understood below, and, on the other hand on the outer wall 100 of the body 10. Each housing 13 is intended to receive another electronic component of the interference suppression circuit such as for example a capacitor 130, as will be understood later. The body 10 also has at least one orifice 14 for crossing the electric cable 30.

De préférence, comme on le voit sur le dessin, la paroi extérieure 100 du corps 10 est munie d'une gorge 1010 sur l'une des faces 101 et les logements 13 y débouchent, ainsi que deux rainures 1020 disposées, chacune, sur l'un des flancs opposés 102.Preferably, as can be seen in the drawing, the outer wall 100 of the body 10 is provided with a groove 1010 on one of the faces 101 and the housings 13 open therein, as well as two grooves 1020, each arranged on the 'one of the opposite sides 102.

Les broches 20 se présentent initialement à la manière d'un H avec deux branches 21 parallèles reliées momentanément par un pont 22 transversal, frangible sécable. Ces broches 20 de préférence plates sont disposées relativement au corps 10 de manière à avoir une partie 201 interne faite seulement d'une partie des branches 21, et une partie 202 externe faite du reste des branches 21 et du pont 22.The pins 20 are initially presented in the manner of an H with two parallel branches 21 momentarily connected by a transverse bridge 22, frangible breakable. These preferably flat pins 20 are arranged relative to the body 10 so as to have an internal part 201 made only of part of the arms 21, and an external part 202 made of the rest of the arms 21 and of the bridge 22.

Le câble 30 est de tout type classique, par exemple avec une gaine 31 isolante et des conducteurs 32 s'il y a lieu aussi isolés individuellement. Ce câble est, de préférence surmoulé dans le corps.The cable 30 is of any conventional type, for example with an insulating sheath 31 and conductors 32 if necessary also individually insulated. This cable is preferably overmolded in the body.

Les jonctions électriques des composants électroniques et du câble avec les broches sont assurées de toute manière classique courante par exemple par contact, soudage, sertissage, etc.The electrical connections of the electronic components and of the cable with the pins are ensured in any conventional conventional manner, for example by contact, welding, crimping, etc.

Comme on le voit, de préférence, les logements débouchent dans la gorge, l'orifice est situé sur l'une des faces et les passages sont situés sur l'un des côtés et de préférence le côté concave.As can be seen, preferably, the housings open into the groove, the orifice is located on one of the faces and the passages are located on one of the sides and preferably the concave side.

Pour fabriquer un connecteur antiparasité selon l'invention, on découpe d'abord dans une planche métallique appropriée les broches 20 avec leur configuration en H. Cette découpe est obtenue par toute technique classique et est éventuellement associée à une opération de mise en forme obtenue simultanément ou au cours d'une autre opération, par exemple pour faire en sorte que les parties interne et externe des broches ne soient pas coplanaires, comme illustré.To make a noise-suppressing connector according to the invention, the pins 20 are first cut out with an H-shaped configuration. This cutting is obtained by any conventional technique and is possibly associated with a shaping operation obtained simultaneously or during another operation, for example to ensure that the internal and external parts of the pins are not coplanar, as illustrated.

Ceci fait, on raccorde électriquement à une même partie des deux branches parallèles qui constitueront la partie interne, un composant électrique et les conducteurs du câble, comme illustré. Ensuite par tout processus connu, on surmoule sur cette partie des deux branches parallèles qui est raccordée électriquement au composant électronique et au câble, le corps en un matériau électriquement isolant approprié de manière à former une chambre où est logé ce composant électronique et un orifice pour la traversée du câble. Comme on le voit, ce corps emprisonne la partie interne des broches et laisse apparents le reste des branches et le pont qui forment, ensemble, la partie externe tout en observant qu'au cours de cette opération de surmoulage on ménage les logements qui débouchent d'une part à l'aplomb de la partie interne de l'une des branches, et de préférence des deux branches, et d'autre part sur la paroi extérieure du corps. Ces logements sont obtenus de toute manière appropriée à l'aide de noyaux mobiles ou non, disposés dans l'empreinte d'un moule.This done, it is electrically connected to the same part of the two parallel branches which will constitute the internal part, an electrical component and the conductors of the cable, as illustrated. Then by any known process, the body is molded on this part of the two parallel branches which is electrically connected to the electronic component and to the cable, in an electrically insulating material so as to form a chamber in which this electronic component is housed and an orifice for the cable crossing. As we can see, this body traps the internal part of the pins and leaves visible the rest of the branches and the bridge which together form the external part while observing that during this overmolding operation the housings which open out are cleaned. on the one hand vertically to the internal part of one of the branches, and preferably of the two branches, and on the other hand to the external wall of the body. These housings are obtained in any suitable manner using movable or non-movable cores, arranged in the imprint of a mold.

Ceci fait, on insère un autre composant électronique dans chacun des logements en assurant le raccordement électrique à la branche correspondante située à l'aplomb du logement qui débouche face à celle-ci.This done, we insert another component electronics in each of the housings by ensuring the electrical connection to the corresponding branch located directly above the housing which opens facing it.

Ensuite, on sépare le pont frangible sécable des branches afin de supprimer le court-circuit électrique que formait ce pont entre les deux branches des broches.Next, the frangible breakable bridge is separated from the branches in order to eliminate the electric short circuit formed by this bridge between the two branches of the pins.

Il est clair que les opérations d'insertion des composants dans les logements et la séparation du pont des branches peuvent être simultanées ou assurées dans un ordre permuté.It is clear that the operations of inserting the components into the housings and the separation of the bridge from the branches can be simultaneous or ensured in a permuted order.

On voit donc que grâce à l'invention, on a fabriqué un connecteur électrique antiparasité qui résout en particulier une des difficultés liée à la mise en place en particulier des condensateurs qui sont relativement fragiles et délicats à mettre en oeuvre, et qui notamment résistent mal aux contraintes de pression et de température qui se manifestent lors d'un surmoulage du corps sur les broches et le câble. En effet grâce à l'invention, ces composants électroniques sont associés physiquement et électriquement au connecteur seulement après l'opération de surmoulage.It can therefore be seen that, thanks to the invention, an anti-interference electrical connector has been manufactured which in particular solves one of the difficulties linked to the installation in particular of the capacitors which are relatively fragile and delicate to implement, and which in particular resist poorly pressure and temperature constraints that manifest themselves when the body is overmolded on the pins and the cable. In fact thanks to the invention, these electronic components are physically and electrically associated with the connector only after the overmolding operation.

Comme on le voit sur la Figure 4, un tel connecteur est associé à la plaque 40 porte-balais dans laquelle sont notamment ménagés une ouverture 41 centrale destinée à laisser libre passage à une partie du moteur tel le collecteur, des couloirs 42 destinés à recevoir des balais ou charbons à base de graphite, et des raccords électriques 43. Cette plaque porte-balais est de tout type classique.As can be seen in FIG. 4, such a connector is associated with the brush holder plate 40 in which there are in particular a central opening 41 intended to allow free passage to a part of the motor such as the manifold, corridors 42 intended to receive graphite-based brushes or carbon brushes, and electrical fittings 43. This brush-holder plate is of any conventional type.

La jonction électrique d'un connecteur antiparasité selon l'invention à une telle plaque porte-balais est faite de toute manière appropriée par exemple par enfichage dans un socle convenablement adapté, par soudage, par sertissage, etc.The electrical connection of a suppressor connector according to the invention to such a brush holder plate is made in any suitable manner, for example by plugging into a suitably adapted base, for example welding, crimping, etc.

Ce qui précède met bien en lumière les particularités de l'invention ainsi que l'intérêt qu'elle offre et les avantages qu'elle procure.The above clearly highlights the particular features of the invention as well as the interest it offers and the advantages it provides.
