Description

La présente invention a pour objet un procédé de fabrication d'un enroulement d'un fil émaillé sur un corps de bobine, constitué, par exemple, d'une ou plusieurs parties en matière plastique moulée. Selon une manière connue, les deux extrémités du fil émaillé sont solidarisées, chacune avec une cosse de raccordement permettant d'établir une liaison électrique avec un circuit extérieur par un simple enfichage de fils dénudés. Comme cela est bien connu aussi, les cosses de raccordement sont enfichées dans des logements appropriées sur une des parties du corps de bobine, et en général, recouverts de coiffes.The present invention relates to a method of manufacturing a winding of an enameled wire on a coil body, consisting, for example, of one or more parts of molded plastic. In a known manner, the two ends of the enameled wire are secured, each with a connection lug making it possible to establish an electrical connection with an external circuit by simply plugging in bare wires. As is also well known, the connection lugs are plugged into appropriate housings on one of the parts of the coil body, and in general, covered with caps.

Le but de l'invention est un procédé de fabrication permettant l'utilisation de machines de bobinage automatiques et évitant la nécessité d'interventions artisanales, telles que notamment le brasage de fis émaillés sur les cosses. Un autre but de l'invention est une cosse adaptée à ce procédé, ainsi qu'une partie de corps de bobine agencée pour recevoir cette cosse.The object of the invention is a manufacturing process allowing the use of automatic winding machines and avoiding the need for artisanal interventions, such as in particular the brazing of enameled fis on the lugs. Another object of the invention is a terminal adapted to this method, as well as a part of the coil body arranged to receive this terminal.

Suivant l'invention, le procédé est caractérisé en ce qu'on enfile, en entaillant l'émaillage, chaque extrémité du fil émaillé de l'enroulement dans une double fente, d'une cosse de raccordement enfichée dans un logement à fentes latérales de la partie de corps de bobine, et en ce qu'on coupe chaque extrémité libre du fil de l'enroulement, notamment sur une des arêtes de la double fente de la cosse.According to the invention, the method is characterized in that one threads, by cutting the enameling, each end of the enameled wire of the winding in a double slot, with a connection lug inserted in a housing with lateral slots of the coil body part, and in that each free end of the winding wire is cut, in particular on one of the edges of the double slot of the terminal.

Suivant l'invention également, une cosse de raccordement constituée d'une base et d'au moins une lame de ressort pour l'application d'un fil dénudé sur cette base, adapté à ce procédé, est caractérisée en ce qu'elle comprend, du côté opposé à la dite lame de ressort, une partie recourbée en direction approximativement parallèle à cette base, cette partie étant taillée et cintrée pour définir une double fente entre les arêtes latérales de la base et les arêtes latérales de la partie recourbée qui se rétrécit jusqu'à un écartement plus faible que le diamètre du fil émaillé utilisé pour l'enroulement.According to the invention also, a connection terminal consisting of a base and at least one spring leaf for the application of a bare wire on this base, suitable for this process, is characterized in that it comprises , on the side opposite to said leaf spring, a curved part in a direction approximately parallel to this base, this part being cut and curved to define a double slit between the lateral edges of the base and the lateral edges of the curved part which narrows to a spacing smaller than the diameter of the enameled wire used for winding.

L'invention est expliquée ci-dessous par rapport à un exemple d'une forme d'exécution représentée au dessin annexé. La figure 1 de ce dessin représente une coupe d'une partie de corps de bobine équipée d'une cosse de raccordement. Les figures 2, 3, et 4 représentent respectivement une vue du dessous de la cosse seule et deux vues en coupe de la figure 2. La figure 5 représente une variante des éléments représentés à la figure 1, recouverts d'une coiffe.The invention is explained below with respect to an example of an embodiment shown in the accompanying drawing. Figure 1 of this drawing shows a section of a coil body part equipped with a connection lug. Figures 2, 3, and 4 respectively show a bottom view of the terminal alone and two sectional views of Figure 2. Figure 5 shows a variant of the elements shown in Figure 1, covered with a cap.

A la figure 1, un corps de bobine 1 solidarisé avec un mandrin dont l'axe est repéré par 2, est surmonté d'un logement 3 à fentes latérales 18. Les fentes 18 se trouvent dans un plan perpendiculaire à l'axe de bobinage ou du mandrin 2. Dans le logement 3 est enfichée une cosse composée d'une base 4, et d'un ensemble de deux lamelles élastiques 5, recourbées. Chaque ensemble de lamelles 5 présente deux ouvertures 6 dans le prolongement de la base à travers laquelle des conducteurs appartenant à un circuit extérieur peuvent être enfilés. Du côté opposé, la cosse présente une partie recourbée, approximativement parallèle à la base 4 et un ergot 8, prévu pour s'engager avec une partie du logement 3, en l'occurrence un trou 9 de ce logement 3. De cette manière, la cosse est fixée par rapport au logement 3 et surtout par rapport aux fentes 18 de ce logement.In FIG. 1, a coil body 1 secured to a mandrel whose axis is marked by 2, is surmounted by a housing 3 with lateral slots 18. The slots 18 lie in a plane perpendicular to the winding axis or of the mandrel 2. In the housing 3 is inserted a terminal composed of a base 4, and of a set of two elastic strips 5, curved. Each set of strips 5 has two openings 6 in the extension of the base through which conductors belonging to an external circuit can be threaded. On the opposite side, the terminal has a curved part, approximately parallel to the base 4 and a lug 8, designed to engage with part of the housing 3, in this case a hole 9 in this housing 3. In this way, the terminal is fixed relative to the housing 3 and especially relative to the slots 18 of this housing.

Comme cela est visible sur les figures 2, 3, et 4, la cosse est conçue pour le raccordement de deux fils dénudés 10 à travers les ouvertures 6. La partie recourbée 7 est taillée et cintrée pour définir une double fente entre les arêtes 11 de la base et les arêtes latérales 12 de la partie recourbée 7. Chacune de ces fentes se rétrécit jusqu'à un écartement plus faible que le diamètre du fil émaillé utilisé. Dès que la cosse est enfichée dans le logement 3, les fentes 18 de celui-ci se trouvent dans le prolongement de la double fente entre les arêtes 11 et 12. Toutefois, les fentes 18 présentent une profondeur limitée telle que le fil émaillé introduit dans la double fente 11, 12 reste localisé dans la zone de serrage efficace de cette dernièreAs can be seen in Figures 2, 3, and 4, the terminal is designed for the connection of two bare wires 10 through the openings 6. The curved part 7 is cut and curved to define a double slot between the edges 11 of the base and the lateral edges 12 of the curved part 7. Each of these slots narrows to a spacing smaller than the diameter of the enameled wire used. As soon as the terminal is inserted into the housing 3, the slots 18 of the latter are located in the extension of the double slot between the edges 11 and 12. However, the slots 18 have a limited depth such that the enameled wire introduced into the double slit 11, 12 remains located in the area of effective clamping of the latter

Lors du procédé de fabrication de l'enroulement, deux cosses sont enfilées dans deux logements 3 du corps de bobine 1, situés de préférence dans un même plan perpendiculaire à l'axe de bobinage 2. Le début du fil émaillé est inséré, à travers les fentes 18 d'un premier logement, dans la double fente de la cosse entre les arêtes 11 et 12 jusqu'à ce qu'il se blesse et se coince, en dénudant ainsi l'âme de cuivre sous la couche d'émail. L'extrémité libre du bout de fil émaillé est coupée, par exemple, sur l'arête vive 11; ensuite, le fil est bobiné sur le corps de bobine 1, et à la fin du bobinage, le fil est inséré dans la double fente entre les arêtes 11 et 12 de l'autre cosse et coupé sur une des arêtes vives 11. L'enroulement est ainsi terminé, sans nécessiter aucune intervention artisanale, tels qu le brasage. Le raccordement à des circuits extérieurs est réalisé au moyen de fils isolés dénudés enfilés à travers les ouvertures 6 et retenus par les arêtes d'extrémité vives des lames 5.During the winding manufacturing process, two lugs are threaded into two housings 3 of the coil body 1, preferably situated in the same plane perpendicular to the winding axis 2. The start of the enameled wire is inserted through the slots 18 of a first housing, in the double slot of the terminal between the edges 11 and 12 until it is injured and wedged, thus stripping the copper core under the enamel layer. The free end of the end of the enameled wire is cut, for example, on the sharp edge 11; then, the wire is wound on the coil body 1, and at the end of winding, the wire is inserted into the double slot between the edges 11 and 12 of the other terminal and cut on one of the sharp edges 11. The winding is thus completed, without requiring any artisanal intervention, such as brazing. The connection to external circuits is carried out by means of stripped insulated wires threaded through the openings 6 and retained by the sharp end edges of the blades 5.

La figure 5 représente une variante d'une cosse selon la figure 2, insérée dans un logement 13 d'une partie de corps de bobine et protégée par une coiffe 14 en matière isolante.FIG. 5 represents a variant of a terminal according to FIG. 2, inserted in a housing 13 of a part of the coil body and protected by a cap 14 made of insulating material.

Le logement 13 comprend ici un téton 15, maintenu au moyen de deux traverses 16. Le téton 15 sert d'une part de partie du logement 13 retenant l'ergot d'arrêt 8 de la cosse, et d'autre part de limiteur pour le déplacement des lames de ressort 5. En effet, lorsque la bobine doit être détachée d'un circuit extérieur, une lame de ressort 5 est soulevée, par exemple au moyen d'un tournevis inséré à travers un trou 17. Afin d'éviter que lors d'une telle manipulation, la lame de ressort 5 ne soit déformée en dépassant la limite élastique, son déplacement est limité par le téton 15. Le téton 15 s'étend dans le prolongement des fentes 18. De ce fait, il sert, en outre, de guide pour le fil émaillé lorsque celui-ci est enfilé dans les fentes 18 et inséré dans la double fente entre les arêtes 11 et 12 de la cosse.The housing 13 here comprises a stud 15, held by means of two crosspieces 16. The stud 15 serves on the one hand as a part of the housing 13 retaining the stop lug 8 of the terminal, and on the other hand as a limiter for the movement of the spring blades 5. In fact, when the coil must be detached from an external circuit, a spring leaf 5 is lifted, for example by means of a screwdriver inserted through a hole 17. In order to avoid that during such manipulation, the spring leaf 5 is not deformed by exceeding the elastic limit, its movement is limited by the stud 15. The stud 15 extends in the extension of the slots 18. Therefore, it serves , in addition, a guide for the enameled wire when the latter is threaded into the slots 18 and inserted into the double slot between the edges 11 and 12 of the terminal.
