De plus, les pattes étant soudées il est impossible de retirer le moteur pas à pas sans endommager les pattes et par conséquent cette technique rend difficile un éventuel remplacement du moteur en cas de défaillance de ce dernier.To achieve the mounting of a stepping motor on a printed circuit board is conventionally welded lugs subject to the stepper motor on conductive tracks of the circuit board. This technique is performed during the assembly process by a welding step. However, this technique is not easy to implement and requires expensive equipment. In addition, the legs being welded it is impossible to remove the stepper motor without damaging the legs and therefore this technique makes it difficult to replace the motor in case of failure of the latter.

DESCRIPTION DETAILLEE DE L'INVENTION En se reportant principalement aux figures 1 et 2, on voit illustré un exemple de réalisation du dispositif de connexion 1. A la figure 1 quatre dispositifs de connexion 1 sont disposés sur la face inférieure du boitier d'un moteur pas à pas 2. A la figure 2, on voit représenté un agrandissement d'un dispositif de connexion 1 de la figure 1. Chaque dispositif de connexion 1 comporte une partie inférieure 3 apte à être solidarisée au moteur 2. Dans l'exemple de réalisation des figures annexées l'assujettissement est réalisé lors de la fabrication du dispositif de connexion qui constitue l'extrémité de la connectique du moteur 2. Toutefois dans d'autres modes de réalisation chaque dispositif de connexion 1 pourra être réalisé indépendamment du moteur 2 est être fixé sur la connectique du moteur par tout moyen approprié et notamment par soudure . Chaque dispositif de connexion 1 comporte en outre une partie comprimable 4, apte à être insérée dans une ouverture 5 prévue dans la carte 6. C'est cette partie 4 particulièrement qui va assurer le blocage du dispositif de connexion 1 sur la carte 6 ainsi que la liaison électrique entre le moteur pas à pas 2 et les bornes de la carte 6 du circuit imprimé.DETAILED DESCRIPTION OF THE INVENTION Referring mainly to FIGS. 1 and 2, an exemplary embodiment of the connection device 1 is illustrated. In FIG. 1, four connection devices 1 are arranged on the lower face of the case of an engine. FIG. 2 shows an enlargement of a connection device 1 of FIG. 1. Each connecting device 1 comprises a lower part 3 adapted to be secured to the motor 2. In the example of FIG. embodiment of the appended figures the fastening is achieved during the manufacture of the connection device which constitutes the end of the connection of the motor 2. However in other embodiments each connection device 1 may be made independently of the engine 2 is to be fixed on the connection of the engine by any appropriate means and in particular by welding. Each connection device 1 further comprises a squeezable portion 4, adapted to be inserted into an opening 5 provided in the card 6. It is this part 4 particularly that will ensure the locking of the connection device 1 on the card 6 as well as the electrical connection between the stepper motor 2 and the terminals of the card 6 of the printed circuit.
A cet effet la structure de la partie comprimable 4 est prévue pour être insérée dans une ouverture 5 dont le diamètre est légèrement inférieur à celui de la partie comprimable 4 dans son état non comprimé. L'insertion de la partie comprimable 4 dans l'ouverture 5 engendre la compression de cette partie 4 qui une fois introduite exerce une pression sur la paroi 7 de l'ouverture 5 créant une liaison mécanique suffisante au maintien du dispositif de connexion 1 sur la carte 6.For this purpose the structure of the compressible part 4 is intended to be inserted into an opening 5 whose diameter is slightly smaller than that of the compressible part 4 in its uncompressed state. The insertion of the compressible part 4 in the opening 5 causes the compression of this part 4 which once introduced exerts a pressure on the wall 7 of the opening 5 creating a sufficient mechanical connection to maintain the connection device 1 on the card 6.
Pour obtenir cet effet de compression on prévoit selon le mode de réalisation avantageux des figures 1 à 4 que la partie comprimable 4 comprend plusieurs bras 8. Ces bras 8 relient la partie inférieure 3 à une partie supérieure 9. Les bras 8 délimitent un espace vide 10 en direction duquel les bras 8 se déforment lors de la mise en compression de la partie compressible 4.To obtain this compression effect is provided according to the advantageous embodiment of Figures 1 to 4 that the compressible portion 4 comprises a plurality of arms 8. These arms 8 connect the lower portion 3 to an upper portion 9. The arms 8 define an empty space 10 in the direction of which the arms 8 deform during compression of the compressible part 4.
On prévoit un nombre de bras 8 égal à quatre pour chaque dispositif de connexion 1 toutefois leur nombre ainsi que les dimensions de ces bras 8 pourront varier en fonction des caractéristiques de compression recherchées pour la partie compressible 4 ; ainsi dans d'autres modes de réalisation le nombre de bras pourrait être compris entre 2 et 6. De manière à faciliter l'introduction de la partie comprimable 4 dans l'ouverture 5, c'est-à-dire à limiter la pression nécessaire à son introduction, tout en conservant, une fois introduite dans l'ouverture 5, un contact constant, on prévoit que les bras 8 de la partie compressible 4 sont bombés en direction de l'extérieur.There is a number of arms 8 equal to four for each connection device 1, however, their number and the dimensions of these arms 8 may vary depending on the desired compression characteristics for the compressible part 4; thus in other embodiments the number of arms could be between 2 and 6. In order to facilitate the introduction of the compressible part 4 in the opening 5, that is to say to limit the necessary pressure at its introduction, while maintaining, once introduced into the opening 5, a constant contact, it is expected that the arms 8 of the compressible portion 4 are curved towards the outside.
Selon le mode de réalisation des figures annexées la partie comprimable 4 est métallique, de cette manière la partie comprimable assure directement la liaison électrique entre le moteur 2 et une piste métallique 12 ménagée dans la paroi 7 de l'ouverture 5. Avantageusement l'ensemble du dispositif de connexion 1 sera réalisé en une seule pièce métallique.According to the embodiment of the appended figures, the compressible part 4 is metallic, in this way the compressible part directly ensures the electrical connection between the motor 2 and a metal track 12 formed in the wall 7 of the opening 5. Advantageously all of the connection device 1 will be made of a single metal part.
Le dispositif de connexion 1 comprend une partie supérieure 9, cette partie facilite le positionnement du dispositif de connexion 1 par apport à l'ouverture 5. De manière avantageuse on prévoit que cette partie supérieure soit allongée et présente un bord arrondi 11 permettant un guidage du dispositif dans l'ouverture 5 de la carte 6.The connection device 1 comprises an upper part 9, this part facilitates the positioning of the connection device 1 by supplying the opening 5. advantageously it is expected that this upper part is elongate and has a rounded edge 11 for guiding the device in the opening 5 of the card 6.
En se reportant cette fois plus particulièrement aux figures 3 et 4 on voit réalisé l'assemblage entre le moteur pas à pas 2 et la carte 6 par le biais des différents dispositifs de connexion 1, la liaison entre les composants est fiable et réversible. Pour accroître la liaison mécanique on prévoit de manière optionnelle des plots de blocage 13 qui coopèrent avec des trous 14 ménagés dans la carte 6 en venant s' encliqueter dans les trous 14. Cette solution permet également de limiter d'éventuels efforts de traction sur les dispositifs de connexion 1 et constitue une garantie supplémentaire du maintien de l'assemblage du moteur pas à pas 2 sur la carte 6.Referring this time more particularly to FIGS. 3 and 4, the assembly between the stepping motor 2 and the card 6 is seen through the various connection devices 1, the connection between the components is reliable and reversible. In order to increase the mechanical connection, it is optionally possible to provide locking studs 13 which cooperate with holes 14 formed in the card 6 by coming into the holes 14. This solution also makes it possible to limit any possible traction forces on the pins. connection devices 1 and is an additional guarantee of maintaining the assembly of the stepping motor 2 on the card 6.
D'autres caractéristiques de l'invention auraient également pu être envisagées par l'homme du métier sans pour autant sortir du cadre de l'invention définie par les revendications ci-après.Other features of the invention could also have been envisaged by those skilled in the art without departing from the scope of the invention defined by the claims below.
Notamment dans un autre mode de réalisation le dispositif comprendra une partie compressible réalisée dans un matériau compressible avec un revêtement métallique assurant la liaison électrique. Dans ce mode de réalisation la partie compressible sera réalisée avec des bras délimitant un espace libre ou à partir d'une forme pleine notamment en forme d'ogive sans espace libre intérieur . In particular in another embodiment the device will comprise a compressible portion made of a compressible material with a metal coating providing the electrical connection. In this embodiment the compressible part will be made with arms delimiting a free space or from a solid form including ogival form without free space inside.
