Abstract

Process consists on cutting off from a band pairs of symmetrical conductive elements (2,3) with connecting parts (2b,3b) around the axis and contacting parts (2a,3a) extending externally. Then the assembly is folded (I) in a U-shape with connecting part projecting downwards and contacting parts projecting upwards. Finally plastic insulator (7) is placed (II) around a pair of conductive elements. Independent claims are also included for a fuse carrier and a whole band of fuse carriers obtained by this process.

Description

La présente invention concerne un procédé de fabrication en série de modules porte-fusible, ainsi que des barrettes de modules porte-fusible.The present invention relates to a process for mass production of fuse holder modules, as well as strips of fuse holder modules.

L'invention s'applique d'une manière générale dans tous les cas où un ou plusieurs fusibles doivent être installés sur une carte à circuit imprimé. L'invention est applicable plus particulièrement, mais non exclusivement, aux mini-fusibles utilisés dans le domaine de l'industrie automobile et destinés à être installés sur une carte électronique, par exemple sur une carte électronique d'un calculateur embarqué dans un véhicule automobile ou encore sur un circuit imprimé de puissance dit circuit PCB, comportant des pistes conductrices et des trous métallisés.The invention is generally applicable in all cases where one or more fuses must be installed on a circuit board printed. The invention is applicable more particularly, but not exclusively for mini-fuses used in industry automotive and intended to be installed on an electronic card, for example on an electronic card of a computer on board a motor vehicle or on a power circuit said PCB circuit, comprising conductive tracks and metallized holes.

Les mini-fusibles doivent être démontables et accessibles aux réparateurs pour pouvoir être facilement remplacés en cas de besoin. Une première technique connue pour installer le ou les fusibles sur une carte à circuit imprimé consiste à prévoir, pour chaque fusible, deux contacts qui sont implantés dans des trous du circuit imprimé et soudés dans leurs trous respectifs. L'ensemble est ensuite placé dans une enveloppe en matière plastique comportant des moyens de guidage du ou des fusibles à installer sur la carte à circuit imprimé. Le ou les fusibles sont installés sur ladite carte après soudage sur cette dernière du ou des contacts destinés à recevoir les fusibles. Une telle technique connue nécessite un nombre d'opérations relativement grand (mise en place de chacun des contacts, soudage de ceux-ci sur la carte à circuit imprimé et branchement de chacun des fusibles dans les contacts y associés), opérations qui ne sont pas toujours facilement automatisables. En outre, cette technique interdit le montage des fusibles en tant que composants CMS (composants à montage en surface).Mini-fuses must be removable and accessible to repairers so that they can be easily replaced if necessary. A first known technique to install the fuse (s) on a card printed circuit consists in providing, for each fuse, two contacts which are installed in holes in the printed circuit and soldered in their respective holes. The whole is then placed in an envelope plastic material comprising means for guiding the fuse or fuses install on the printed circuit board. The fuse (s) are installed on said card after welding on the latter of the contact or contacts intended for receive the fuses. Such a known technique requires a number relatively large operations (establishment of each of the contacts, soldering of these on the printed circuit board and connection of each of the fuses in the associated contacts), operations which are not not always easy to automate. In addition, this technique prohibits mounting the fuses as SMD components (components with surface mounting).

Une autre technique connue consiste à insérer à force les contacts dans des logements respectifs d'un boítier en matière plastique, de telle façon que les broches de connexion respectivement associées aux contacts fassent saillie sur une face du boítier. Ensuite, le boítier est présenté devant la carte à circuit imprimé et les broches saillantes des contacts sont insérées dans les trous métallisés de la carte à circuit imprimé et soudées auxdits trous par exemple par soudage à la vague. Les fusibles peuvent être branchés dans les contacts du boítier avant ou après l'opération de soudage des broches de connexion dans les trous métallisés de la carte à circuit imprimé.Another known technique consists in forcibly inserting the contacts in respective housings of a plastic housing, such so that the connection pins respectively associated with the contacts protrude from one side of the housing. Then the case is presented in front the printed circuit board and the protruding pins of the contacts are inserted into the metalized holes of the printed circuit board and soldered to said holes, for example by wave welding. The fuses can be plugged into the housing contacts before or after the welding operation connection pins in the metallic holes of the circuit board printed.

Là encore, cette technique connue comporte un nombre d'opérations relativement important (insertion de chaque contact dans son logement respectif du boítier, branchement de chaque fusible, etc) et elle interdit le montage du boítier en tant que composant CMS.Again, this known technique involves a number of operations relatively important (insertion of each contact in its housing respective case, connection of each fuse, etc.) and it prohibits mounting the housing as a CMS component.

En outre, dans ces deux techniques connues, lorsque plusieurs fusibles ont une borne reliée électriquement à un même pôle d'une source de tension continue, il faut prévoir sur la carte à circuit imprimé une piste de puissance capable de véhiculer une intensité de courant relativement importante. La piste de puissance doit donc avoir une épaisseur et/ou une largeur de cuivre relativement importante. Or, il n'est ni rationnel ni économique de donner à la couche de cuivre de la plaque à circuit imprimé une épaisseur importante, dans la mesure où les autres pistes conductrices du circuit imprimé transportent usuellement des intensités de courant nettement plus faible que celles de la piste de puissance et ne nécessitent pas une épaisseur de cuivre si importante. D'autre part, une piste de puissance de grande largeur occupe beaucoup de place sur une carte à circuit imprimé, au détriment des autres pistes conductrices, dont les trajets pourraient être plus simples et plus courts, et au détriment des dimensions totales de la carte à circuit imprimé qui, sans cela, pourrait être réduite.Furthermore, in these two known techniques, when several fuses have a terminal electrically connected to the same pole of a source DC voltage, a track must be provided on the printed circuit board of power capable of carrying a relatively current intensity important. The power track must therefore have a thickness and / or a relatively large copper width. However, it is neither rational nor economical to give the copper layer of the printed circuit board a significant thickness, insofar as the other conductive tracks of the printed circuit usually carry current intensities significantly lower than those of the power track and do not require not such a large thickness of copper. On the other hand, a track of wide power occupies a lot of space on a board printed circuit, to the detriment of other conductive tracks, including journeys could be simpler and shorter, and at the expense of total dimensions of the printed circuit board which otherwise could be scaled down.

La présente invention a donc pour but de remédier aux inconvénients de la technique antérieure exposés ci-dessus.The object of the present invention is therefore to remedy the drawbacks of the prior art set out above.

A cet effet, l'invention fournit un procédé de fabrication en série de modules porte-fusible, caractérisé en ce qu'il comprend les étapes consistant :

  • a) à découper clans une bande de métal conducteur une succession de paires de pièces conductrices, une paire étant prévue pour chaque module porte-fusible, chaque pièce conductrice comportant une partie de contact, destinée à l'établissement d'une liaison électrique et mécanique détachable avec une patte de connexion d'un fusible, et une partie de connexion destinée à l'établissement d'une liaison électrique avec une carte à circuit imprimé, le découpage étant effectué de telle façon que les deux pièces conductrices de chaque paire de pièces conductrices soient disposées symétriquement de part et d'autre de l'axe médian longitudinal de la bande de métal conducteur et s'étendent transversalement par rapport audit axe, les parties de connexion des deux pièces conductrices de chaque paire s'étendant l'une vers l'autre vers ledit axe médian longitudinal, tandis que les parties de contact des deux pièces conductrices de chaque paire s'étendent dans des directions opposées, et de telle façon que des éléments de shuntage soient ménagés dans la région médiane de la bande de métal conducteur, chaque élément de shuntage reliant entre elles quatre pièces conductrices appartenant à deux paires adjacentes de pièces conductrices ;
  • b) à plier en U la bande de métal conducteur autour de deux lignes de pliage parallèles à l'axe médian longitudinal de ladite bande, de telle façon que les éléments de shuntage restent dans le plan de la bande, que les parties de contact des pièces conductrices se dressent perpendiculairement audit plan d'un côté de celui-ci et que les parties de connexion desdites pièces conductrices soient en saillie de l'autre côté dudit plan ;
  • c) à adjoindre à la bande de métal conducteur pliée en U des supports en matière isolante moulée, de telle façon que chaque support emprisonne partiellement une paire de pièces conductrices, les deux parties de contact et les deux parties de connexion de ladite paire restant exposées, et chaque élément de shuntage restant exposé entre deux supports adjacents, grâce à quoi on obtient une succession de modules porte-fusible, reliés les uns aux autres au moins par les éléments de shuntage.
    • To this end, the invention provides a process for mass production of fuse holder modules, characterized in that it comprises the steps consisting:
  • a) cutting from a strip of conductive metal a succession of pairs of conductive parts, a pair being provided for each fuse holder module, each conductive part comprising a contact part, intended for establishing an electrical and mechanical connection detachable with a connection lug of a fuse, and a connection part intended for establishing an electrical connection with a printed circuit board, the cutting being carried out in such a way that the two conductive parts of each pair of parts conductive are arranged symmetrically on either side of the longitudinal median axis of the conductive metal strip and extend transversely with respect to said axis, the connecting parts of the two conductive parts of each pair extending one towards the other towards said longitudinal median axis, while the contact parts of the two conductive parts of each pair extend in directions opposite sections, and in such a way that shunt elements are provided in the middle region of the conductive metal strip, each shunt element connecting together four conductive parts belonging to two adjacent pairs of conductive parts;
  • b) bending the strip of conductive metal in a U around two fold lines parallel to the longitudinal central axis of said strip, so that the shunt elements remain in the plane of the strip, that the contact parts of the conductive parts stand perpendicular to said plane on one side thereof and the connection parts of said conductive parts project from the other side of said plane;
  • c) adding to the strip of conductive metal folded in a U supports of molded insulating material, so that each support partially traps a pair of conductive parts, the two contact parts and the two connection parts of said pair remaining exposed , and each shunt element remaining exposed between two adjacent supports, whereby a succession of fuse holder modules is obtained, connected to each other at least by the shunt elements.

    • le découpage de la bande de métal conducteur est effectué de telle façon que chaque élément de shuntage comporte une partie centrale située sur l'axe médian longitudinal de la bande et quatre barrettes obliques reliant ladite partie centrale respectivement auxdites quatre pièces conductrices ;

    • l'adjonction des supports est effectuée par insertion de la bande dans les supports qui ont été préalablement moulés ;
    • le moulage de chaque support est effectué de telle façon que deux parois de guidage sont formées d'un seul tenant avec le support, les deux parois de guidage se dressant perpendiculairement audit plan de la bande à l'extérieur des branches du U formées respectivement par les parties de contact de la paire de pièces conductrices partiellement emprisonnées dans le support, pour servir de guide à un fusible lors de son branchement dans lesdites parties de contact ;

    • au cours de l'opération de segmentation les éléments de shuntage sont partiellement éliminés de telle façon que subsistent seulement les parties des éléments de shuntage reliant entre elles les pièces conductrices qui sont situées d'un même côté de l'axe médian longitudinal de la bande de métal conducteur ;

    L'invention fournit également un module porte-fusible et une barrette de modules porte-fusible obtenus par le procédé présentant une ou plusieurs des caractéristiques indiquées ci-dessus.The invention also provides a fuse holder module and a strip. fuse holder modules obtained by the process having one or more many of the features listed above.

    L'invention fournit également une barrette de modules porte-fusible du type comprenant un support en matière isolante portant plusieurs paires de pièces conductrices, une paire par module porte-fusible, chaque pièce conductrice comportant une partie de contact, qui est destinée à l'établissement d'une liaison électrique et mécanique détachable avec une patte de connexion d'un fusible, et une partie de connexion qui est destinée à l'établissement d'une liaison électrique avec une carte à circuit imprimé, lesdites paires de pièces conductrices étant espacées le long de l'axe médian longitudinal de la barrette de telle façon que l'une des deux pièces conductrices de chaque paire se trouve d'un côté dudit axe médian et que l'autre pièce conductrice se trouve de l'autre côté dudit axe médian, caractérisée en ce que la barrette contient un élément de shuntage qui relie électriquement toutes les pièces conductrices situées d'un côté dudit axe médian longitudinal.The invention also provides a strip of fuse holder modules of the type comprising a support of insulating material carrying several pairs of conductive parts, one pair per fuse holder module, each conductive part comprising a contact part, which is intended for establishing a detachable electrical and mechanical connection with a connection lug of a fuse, and a connection part which is intended establishing an electrical connection with a printed circuit board, said pairs of conductive parts being spaced along the median axis longitudinal of the bar so that one of the two pieces conductive of each pair is on one side of said median axis and that the other conductive part is on the other side of said median axis, characterized in that the bar contains a shunting element which connects electrically all conductive parts located on one side of said axis longitudinal median.

    Grâce à la présente invention, les deux pièces conductrices (contacts) de chaque module porte-fusible sont emprisonnées dans un support en matière isolante. En conséquence, les deux pièces conductrices ou contacts de chaque module porte-fusible, qu'ils soient individuels ou qu'ils fassent parti d'une barrette de modules porte-fusible, n'ont pas besoin d'être insérées individuellement dans des trous d'une carte à circuit imprimé ou dans un logement d'un boítier commun à plusieurs fusibles, ce qui simplifie déjà les opérations de mise en place des fusibles sur une carte à circuit imprimé.Thanks to the present invention, the two conductive parts (contacts) of each fuse holder module are trapped in a support insulating material. As a result, the two conductive parts or contacts of each fuse holder module, whether individual or from a strip of fuse holder modules, do not need to be individually inserted into holes in a printed circuit board or in a housing of a common box with several fuses, which simplifies already the operations of installation of fuses on a circuit board printed.

    En outre, comme déjà indiqué plus haut, selon la manière dont l'opération de pliage est effectuée, l'invention permet d'obtenir des modules porte-fusible individuels ou des barrettes de modules porte-fusible constituant soit des composants à piquer sur une carte à circuit imprimé, soit des composants CMS. Ceci offre de plus larges possibilités quant aux techniques utilisables pour l'implantation des modules porte-fusible ou des barrettes de modules porte-fusible sur une carte à circuit imprimé. En outre, les modules porte-fusible peuvent être conditionnés de façon à être utilisables par des machines automatiques d'implantation de composants sur des cartes à circuit imprimé.Furthermore, as already indicated above, depending on how the folding operation is carried out, the invention makes it possible to obtain modules individual fuse holders or fuse holder modules constituting either components to be stitched onto a printed circuit board, either CMS components. This offers wider possibilities for techniques that can be used to install fuse holder modules or strips of fuse holder modules on a printed circuit board. In in addition, the fuse holder modules can be packaged so as to be usable by automatic component implantation machines on printed circuit boards.

    Si on le désire, les fusibles peuvent être facilement mis en place de manière automatique sur les modules porte-fusible avant l'opération de segmentation de la bande. Ceci facilite donc le travail du fabricant des cartes électroniques.If desired, the fuses can be easily fitted from automatically on the fuse holder modules before the operation of strip segmentation. This therefore facilitates the work of the manufacturer of the e-cards.

    Enfin, dans le cas où le procédé selon l'invention conduit à une barrette de modules porte-fusible qui contient un élément de shuntage reliant électriquement toutes les pièces conductrices situées d'un même côté de l'axe médian longitudinal de la bande de métal conducteur, qui est aussi l'axe médian longitudinal de la barrette de modules porte-fusible, il est alors possible de se passer d'une piste conductrice de puissance sur la carte à circuit imprimé, ou d'en réduire sensiblement la longueur. Cela permet aussi de réduire au moins une dimension de la carte à circuit imprimé et de simplifier éventuellement le trajet des autres pistes conductrices, voire de réduire la longueur de certaines d'entre elles si elles devaient auparavant contourner la piste de puissance pour éviter toute interférence avec elle.Finally, in the case where the method according to the invention leads to a strip of fuse holder modules which contains a shunt element electrically connecting all the conductive parts located in the same side of the longitudinal center line of the conductive metal strip, which is also the longitudinal median axis of the fuse holder module strip, it is then possible to do without a power conducting track on the printed circuit board, or to significantly reduce its length. That also reduces at least one dimension of the circuit board printed and possibly simplify the route of other tracks conductive, or even reduce the length of some of them if they previously had to bypass the power track to avoid any interference with it.

    En se référant maintenant à la figure 1, on peut voir un tronçon d'une bande 1 (représentée en traits mixtes) en métal conducteur, par exemple à base de cuivre, dans laquelle a été découpée une succession de paires de pièces conductrices 2 et 3 qui sont espacées le long de la bande 1. Chaque pièce conductrice 2 ou 3 comporte une partie de contact 2a ou 3a et une partie de connexion 2b ou 3b.Referring now to Figure 1, we can see a section a strip 1 (shown in broken lines) of conductive metal, by example based on copper, from which a succession of pairs of conductive parts 2 and 3 which are spaced along the strip 1. Each conductive part 2 or 3 has a contact part 2a or 3a and a connection part 2b or 3b.

    Les parties de contact 2a et 3a de chaque paire de pièces conductrices 2 et 3 sont destinées à établir une liaison électrique et mécanique détachable respectivement avec les deux pattes de connexion d'un fusible comme on le verra plus loin. De préférence, les parties de contact 2a et 3a sont découpées en forme de lyre plate. Une telle forme en lyre plate permet d'obtenir une forte pression de serrage pour un faible déplacement, donc un bon contact électrique avec les pattes de connexion du fusible et une forte force de maintien desdites pattes de connexion entre les deux branches de chaque partie de contact en forme de lyre plate. Les parties de connexion 2b et 3b de chaque paire de pièces conductrices 2 et 3 sont destinées à établir une liaison électrique avec une carte à circuit imprimé comme on le verra également plus loin.The contact parts 2a and 3a of each pair of parts conductors 2 and 3 are intended to establish an electrical connection and mechanical detachable respectively with the two connection tabs of a fuse as we will see later. Preferably, the parts of contact 2a and 3a are cut in the shape of a flat lyre. Such a form in flat lyre provides high clamping pressure for low displacement, therefore good electrical contact with the connection lugs of the fuse and a strong holding force of said connection tabs between the two branches of each contact part in the form of a flat lyre. The connection parts 2b and 3b of each pair of conductive parts 2 and 3 are intended to establish an electrical connection with a circuit board printed as we will also see later.

    Les deux pièces conductrices 2 et 3 de chaque paire de pièces conductrices sont disposées symétriquement de part et d'autre de l'axe médian longitudinal 4 de la bande de métal conducteur 1 et elles s'étendent transversalement par rapport audit axe. Les parties de connexion 2b et 3b des deux pièces conductrices 2 et 3 de chaque paire s'étendent l'une vers l'autre vers l'axe médian longitudinal 4, tandis que les parties de contact 2a et 3a des deux pièces conductrices 2 et 3 de chaque paire s'étendent dans des directions opposées, chacune vers un côté longitudinal respectif de la bande 1.The two conductive parts 2 and 3 of each pair of parts conductive are arranged symmetrically on either side of the axis longitudinal median 4 of the conductive metal strip 1 and they extend transversely to said axis. Connection parts 2b and 3b of the two conductive parts 2 and 3 of each pair extend one towards the other towards the longitudinal median axis 4, while the contact parts 2a and 3a of the two conductive parts 2 and 3 of each pair extend in opposite directions, each toward a respective longitudinal side of the band 1.

    Le découpage de la bande 1 est en outre effectué de telle façon que des éléments de shuntage 5 soient ménagés dans la région médiane de la bande 1 entre les paires de pièces conductrices 2, 3. Chaque élément de shuntage 5 relie entre elles quatre pièces conductrices appartenant à deux paires adjacentes de pièces conductrices 2, 3.The cutting of the strip 1 is also carried out in such a way that shunt elements 5 are provided in the middle region of the strip 1 between the pairs of conductive parts 2, 3. Each element of shuntage 5 connects four conductive parts belonging to two adjacent pairs of conductive parts 2, 3.

    De préférence, chaque élément de shuntage 5 comporte une partie centrale 5a située sur l'axe 4, et quatre barrettes obliques 5b à 5e, qui relient la partie centrale 5a respectivement à quatre pièces conductrices 2 et 3 appartenant à deux paires adjacentes de pièces conductrices. La partie centrale 5a de chaque élément de shuntage 5 peut avoir par exemple une forme circulaire ou annulaire, avec un trou 6 en son milieu, tous les trous 6 étant régulièrement espacés le long de l'axe 4 et pouvant servir, de façon connue en soi, à l'entraínement pas à pas de la bande 1.Preferably, each shunting element 5 has a part central unit 5a located on axis 4, and four oblique bars 5b to 5e, which connect the central part 5a respectively to four conductive parts 2 and 3 belonging to two adjacent pairs of conductive parts. The part central unit 5a of each shunting element 5 may for example have a circular or annular shape, with a hole 6 in the middle, all holes 6 being regularly spaced along axis 4 and being able to serve, so known per se, to the step-by-step training of the band 1.

    Après avoir été découpée comme décrit en référence à la figure 1, la bande 1 peut être ensuite soumise à un traitement contre l'oxydation et enroulée sous la forme d'une galette et stockée temporairement en attendant d'être soumise aux autres opérations qui seront décrites plus loin. Le procédé de traitement contre l'oxydation et les appareils pour sa mise en oeuvre son bien connus et n'ont pas besoin d'être décrits.After having been cut as described with reference to FIG. 1, the strip 1 can then be subjected to an oxidation treatment and rolled up in the form of a pancake and temporarily stored in waiting to be subjected to the other operations which will be described more far. The oxidation treatment process and apparatuses for its its well known implementation and need not be described.

    La bande 1 découpée et éventuellement traitée contre l'oxydation est ensuite amenée à passer successivement à travers un poste de pliage I, un poste II de moulage par injection ou d'insertion, un poste III d'insertion de composant et enfin un poste IV de segmentation comme montré dans la figure 2. Bien que dans la figure 2 les postes I à IV soient représentés relativement proches les uns des autres pour la commodité du dessin, ces différents postes peuvent en réalité se trouver à une distance substantiellement plus grande les uns des autres.The strip 1 cut and possibly treated against oxidation is then brought successively through a folding station I, a post II for injection molding or insertion, a post III for inserting component and finally an IV segmentation post as shown in the figure 2. Although in figure 2 the stations I to IV are represented relatively close to each other for the convenience of drawing, these different stations can actually be at a distance substantially larger from each other.

    Dans le poste I, la bande 1 est pliée en U autour de deux lignes de pliage parallèles à l'axe médian longitudinal de la bande comme montré dans la figure 3. Au cours de cette opération de pliage, les éléments de shuntage 5 restent dans le plan de la bande, tandis que les parties de contact 2a et 3a des pièces conductrices 2 et 3 se dressent perpendiculairement audit plan d'un côté de celui-ci. Les parties de connexion 2b et 3b font saillie de l'autre côté dudit plan, par exemple perpendiculairement à celui-ci lorsque les parties 2b et 3b sont destinées à être plantées dans des trous métallisés d'une carte à circuit imprimé. In station I, the strip 1 is folded into a U around two lines of folding parallel to the longitudinal median axis of the strip as shown in figure 3. During this folding operation, the elements of shuntage 5 remain in the band plane, while the parts of contact 2a and 3a of the conductive parts 2 and 3 stand up perpendicular to said plane on one side thereof. The parts of connection 2b and 3b project from the other side of said plane, for example perpendicular to it when parts 2b and 3b are intended to be planted in metallized holes on a printed circuit board.

    Dans un mode de réalisation de l'invention, le poste II est un poste de moulage par injection dans lequel des supports 7 en une matière thermoplastique isolante sont moulés sur la bande 1. Dans le mode de réalisation représenté sur la figure 2, à chaque arrêt de la bande 1 dans le poste II, il est formé à chaque fois un seul support 7 sur ladite bande, cette dernière étant alors avancée à chaque fois d'un pas correspondant au pas des paires des pièces conductrices 2, 3 le long de la bande 1. Toutefois, il va de soi que le poste de moulage pourrait être agencé pour former simultanément plusieurs supports 7 sur la bande 1 à chaque arrêt de celle-ci dans le poste II. Dans ce dernier cas, la bande 1 est avancée à chaque fois d'un pas correspondant à un multiple du pas des pièces conductrices 2, 3 le long de la bande 1.In one embodiment of the invention, station II is a injection molding in which supports 7 made of a material insulating thermoplastic are molded on the strip 1. In the mode of embodiment shown in FIG. 2, at each stop of the strip 1 in the station II, a single support 7 is formed each time on said strip, this last being then advanced each time by a step corresponding to the step pairs of conductive parts 2, 3 along the strip 1. However, it will of course the molding station could be arranged to form simultaneously several supports 7 on the strip 1 at each stop thereof in post II. In the latter case, band 1 is advanced each time times of a step corresponding to a multiple of the step of the conductive parts 2, 3 along strip 1.

    Dans un autre mode de réalisation de l'invention, le poste II est un poste d'insertion, dans lequel la bande 1 est insérée dans des supports qui sont semblables aux supports 7 et qui ont été préalablement moulés en une matière thermoplastique isolante.In another embodiment of the invention, station II is a insertion station, in which the strip 1 is inserted into supports which are similar to the supports 7 and which have been previously molded in one insulating thermoplastic material.

    Lors de l'opération de moulage ou d'insertion, dans le poste II, chaque paire de pièces conductrices 2, 3 est partiellement emprisonnée dans le support 7 en matière isolante, de telle façon que les deux parties de contact 2a et 3a et les deux parties de connexion 2b et 3b de la paire de pièces conductrices 2, 3 restent exposées et que chaque élément de shuntage 5 reste exposé entre deux supports adjacents 7, comme montré dans les figures 2, 4 et 6. Dans le mode de réalisation de la figure 2, on obtient alors une succession de modules porte-fusible 8, qui ont chacun leur propre support 7 et qui sont reliés les uns aux autres par les éléments de shuntage 5.During the molding or insertion operation, in station II, each pair of conductive parts 2, 3 is partially trapped in the support 7 of insulating material, so that the two parts of contact 2a and 3a and the two connection parts 2b and 3b of the pair of conductive parts 2, 3 remain exposed and that each element of shunt 5 remains exposed between two adjacent supports 7, as shown in Figures 2, 4 and 6. In the embodiment of Figure 2, we then obtains a succession of fuse holder modules 8, which each have their own support 7 and which are connected to each other by the elements shunt 5.

    Cependant, dans le cas où plusieurs supports 7 sont adjoints par moulage ou par insertion en une seule opération sur la bande 1 dans le poste II, les supports 7 peuvent être alors aussi reliés entre eux par au moins une liaison 9 en matière isolante, venue de moulage avec les supports 7, comme on le verra plus loin en référence aux figures 7 à 10. Dans ce dernier cas, le procédé selon l'invention permet de former des barrettes 10 comportant chacune plusieurs modules porte-fusible 8. However, in the case where several supports 7 are added by molding or insertion in a single operation on the strip 1 in the station II, the supports 7 can then also be interconnected by at at least one connection 9 made of insulating material, molded with the supports 7, as will be seen below with reference to FIGS. 7 to 10. In the latter case, the method according to the invention makes it possible to form strips 10 each comprising several fuse holder modules 8.

    Au cours de l'opération de moulage des supports 7, deux parois de guidage 11 et 12 peuvent être aussi formées d'un seul tenant avec chaque support 7. Comme cela est plus particulièrement visible dans les figures 5 et 6 et également dans les figures 7, 8, 12 et 13, les deux parois de guidage 11 et 12 formées sur chaque support 7 se dressent perpendiculairement au plan de la bande 1 à l'extérieur des branches du U formées respectivement par les parties de contact 2a et 3a de la paire de pièces conductrices 2, 3 partiellement noyées dans le support 7.During the molding operation of the supports 7, two walls of guide 11 and 12 can also be formed in one piece with each support 7. As is more particularly visible in Figures 5 and 6 and also in FIGS. 7, 8, 12 and 13, the two guide walls 11 and 12 formed on each support 7 stand perpendicular to the plane of the strip 1 outside the branches of the U formed respectively by the contact parts 2a and 3a of the pair of conductive parts 2, 3 partially embedded in the support 7.

    Les deux parois 11 et 12 sont destinées à servir de guide pour un fusible ou mini-fusible 13 de type connu, lorsque celui-ci est mis en place sur le module porte-fusible 8 dans le poste III. Chaque fusible 13 a, de façon connue, un corps 14 en une matière isolante et de forme approximativement parallèlépipédique, sur une face duquel font saillie deux pattes planes de connexion 15 et 16. A l'intérieur du corps 14 est noyé un élément conducteur qui est relié électriquement aux pattes 15 et 16 et qui est calibré pour fondre lorsqu'il est parcouru par un courant ayant une intensité prédéterminée. La largeur de l'intervalle entre les deux branches de chaque partie de contact 2a ou 3a en forme de lyre, à l'endroit où cet intervalle est le plus étroit, est dimensionnée de façon à avoir une valeur légèrement plus petite que l'épaisseur des pattes de connexion 15 et 16 du fusible 13.The two walls 11 and 12 are intended to serve as a guide for a fuse or mini-fuse 13 of known type, when the latter is fitted on the fuse holder module 8 in station III. Each fuse 13 has, known manner, a body 14 of an insulating material and of shape approximately parallelepiped, on one side of which two protrude flat connection lugs 15 and 16. Inside the body 14 is embedded a conductive element which is electrically connected to lugs 15 and 16 and which is calibrated to melt when it is traversed by a current having a predetermined intensity. The width of the gap between the two branches of each lyre-shaped contact part 2a or 3a, where this interval is the narrowest, is dimensioned so as to have a value slightly smaller than the thickness of the connection lugs 15 and 16 of the fuse 13.

    Chacune des deux parois de guidage 11 et 12 a, lorsqu'elle est vue en bout, c'est-à-dire dans la direction d'insertion d'un fusible 13 entre elles, la forme d'un canal en U peu profond, de telle façon que le fusible 13 soit guidé sur quatre faces lorsqu'il est inséré entre les parois de guidage 11 et 12 du module porte-fusible 8, tout en permettant la manipulation du fusible 13 à l'aide d'une pince.Each of the two guide walls 11 and 12 a, when viewed in end, that is to say in the direction of insertion of a fuse 13 between them, the shaped like a shallow U-shaped channel, so that fuse 13 is guided on four sides when inserted between the guide walls 11 and 12 of the fuse holder module 8, while allowing the manipulation of the fuse 13 using pliers.

    Au cours de l'opération de moulage des supports 7, une autre paroi 17 peut être également formée d'un seul tenant avec chaque support 7 de manière à se dresser perpendiculairement au plan de la bande de métal conducteur, entre les deux parties de contact 2a et 3a de chaque paire de pièces conductrices 2 , 3, comme cela est plus particulièrement visible dans la figure 5 et également dans les figures 7, 8, 12 et 13. Cette paroi 17 est destinée à servir de butée pour limiter la profondeur d'insertion du fusible 13 dans le module porte-fusible 8, comme cela est notamment visible dans la figure 5.During the molding operation of the supports 7, another wall 17 can also be formed integrally with each support 7 of so as to stand perpendicular to the plane of the metal strip conductor, between the two contact parts 2a and 3a of each pair of conductive parts 2, 3, as is more particularly visible in Figure 5 and also in Figures 7, 8, 12 and 13. This wall 17 is intended to serve as a stop to limit the insertion depth of the fuse 13 in the fuse holder module 8, as can be seen in particular in Figure 5.

    Dans le poste IV, la bande 1 découpée, pliée et munie de supports 7 moulés pour les modules porte-fusible 8 est segmentée à l'aide d'un outil de coupe approprié. Dans le mode de réalisation de la figure 2 où les supports 7 sont indépendants les uns des autres et reliés entre eux seulement par les éléments de shuntage 5, l'opération de segmentation peut alors simplement consister à éliminer complètement par découpage les éléments de shuntage 5. On obtient alors des modules porte-fusible 8 individuels comme celui représenté sur les figures 12 et 13, chaque porte-fusible individuel 8 étant éventuellement garni d'un fusible 13 si un tel fusible y a été inséré au cours du passage du module porte-fusible dans le poste III.In station IV, the strip 1 cut, folded and provided with supports 7 molded for the fuse holder modules 8 is segmented using a suitable cut. In the embodiment of Figure 2 where the supports 7 are independent of each other and linked together only by the shunting elements 5, the segmentation operation can then simply consist of completely eliminating the shunting elements 5. We then obtain individual 8 fuse holder modules like the one shown in Figures 12 and 13, each individual fuse holder 8 being possibly fitted with a fuse 13 if such a fuse was inserted there during the passage of the fuse holder module in station III.

    Sur la figure 12, on peut voir que le fusible 13 est retenu dans le module porte-fusible 8 par deux ergots d'encliquetage 18 et 19 situés sur les faces internes mutuellement opposées des parois de guidage 11 et 12, à l'extrémité supérieure de celles-ci. Ces ergots d'encliquetage 18 et 19 peuvent être formés d'un seul tenant avec les parois 11 et 12 lors de l'opération de moulage dans le poste II.In FIG. 12, it can be seen that the fuse 13 is retained in the fuse holder module 8 by two snap pins 18 and 19 located on the mutually opposite internal faces of the guide walls 11 and 12, at the upper end of these. These snap pins 18 and 19 can be formed in one piece with walls 11 and 12 when the molding operation in station II.

    Les modules porte-fusible individuels 8 ainsi obtenus peuvent être par exemple livrés en vrac, en bande alvéolée, en tube, etc..., ou encore, ils peuvent être collés avec un pas d'espacement prédéfini p sur une bande souple 21 recouverte d'une couche adhésive comme montré sur la figure 14. La bande 21 garnie de modules 8 est ensuite enroulée sous la forme d'une galette utilisable dans un processus de pose automatique de composants sur une carte à circuit imprimé.The individual fuse holder modules 8 thus obtained can be for example delivered in bulk, honeycomb, tube, etc., or can be pasted with a predefined spacing step p on a strip flexible 21 covered with an adhesive layer as shown in FIG. 14. The strip 21 furnished with modules 8 is then wound up in the form of a wafer usable in an automatic component installation process on a printed circuit board.

    Dans un autre mode de réalisation de l'invention, lorsque les supports 7 des modules porte-fusible 8 sont aussi reliés entre eux par au moins une liaison 9 en matière isolante, par exemple deux liaisons 9, comme montré sur les figures 7, 9 et 10, l'opération de segmentation peut être effectuée en coupant les deux liaisons 9 et l'élément de shuntage 5 entre deux modules porte-fusible 8 adjacents, tous les n modules porte-fusible, n étant un nombre entier prédéterminé. Dans ces conditions, on obtient des barrettes 10 comportant chacune n modules porte-fusible 8, par exemple trois modules porte-fusible comme montré dans la figure 7. Dans ce cas, le nombre n est égal à trois, mais il va de soi qu'il pourrait être plus petit ou plus grand que trois.In another embodiment of the invention, when the supports 7 of the fuse holder modules 8 are also connected to each other by at least one connection 9 made of insulating material, for example two connections 9, as shown in figures 7, 9 and 10, the segmentation operation can be carried out by cutting the two links 9 and the shunt element 5 between two adjacent fuse holder modules 8, all n fuse holder modules, n being a predetermined whole number. Under these conditions, we obtains bars 10 each comprising n fuse holder modules 8, by example three fuse holder modules as shown in figure 7. In this case the number n equals three, but it stands to reason that it could be more small or larger than three.

    Dans la barrette 10 représentée sur la figure 7, tous les éléments de shuntage 5 ont été complètement éliminés par découpage afin de rendre les modules porte-fusible 8 électriquement indépendants les uns des autres.In the bar 10 represented in FIG. 7, all the elements of shuntage 5 have been completely removed by cutting to make them fuse holder modules 8 electrically independent from each other.

    En choisissant un outil de coupe approprié, il est également possible de faire en sorte que chaque élément de shuntage 5 ne soit coupé que partiellement, comme montré dans la figure 8. Dans ce cas, dans la barrette 10 obtenue après segmentation, seules subsistent les parties des éléments de shuntage 5 reliant entre elles les pièces conductrices qui sont situées d'un même côté de l'axe médian longitudinal de la bande de métal conducteur, par exemple, les pièces conductrices 2 comme montré dans la figure 8. Etant donné que dans ce cas les supports 7 des divers modules porte-fusible 8 constituant la barrette 10 restent reliés entre eux par une partie des éléments de shuntage 5 après segmentation de la bande et découpage des éléments de shuntage, les liaisons 9 situées entre les supports 7 adjacents du même côté de l'axe médian longitudinal que les parties restantes des éléments de shuntage 5 peuvent être omises comme montré dans les figures 8 et 11. Cela permet non seulement d'économiser de la matière isolante, mais également de faciliter l'opération de segmentation, puisqu'il n'y a plus qu'une seule liaison 9 à couper entre deux modules porte-fusible 8 adjacents pour détacher les barrettes 10 les unes des autres.By choosing an appropriate cutting tool, it is also possible to make sure that each shunt element 5 is cut only partially, as shown in figure 8. In this case, in the bar 10 obtained after segmentation, only the parts of the elements remain bridge 5 connecting together the conductive parts which are located on the same side of the longitudinal central axis of the metal strip conductor, for example, the conductive parts 2 as shown in the Figure 8. Since in this case the supports 7 of the various modules fuse holder 8 constituting the bar 10 remain interconnected by a part of the shunting elements 5 after segmentation of the strip and cutting of the shunt elements, the connections 9 located between the supports 7 adjacent to the same side of the longitudinal median axis as the remaining parts of shunt elements 5 can be omitted as shown in Figures 8 and 11. This not only saves insulating material, but also to facilitate the operation of segmentation, since there is only one link 9 left to cut between two adjacent fuse holder modules 8 for detaching the bars 10 each other.

    La forme de réalisation de la barrette 10 de modules porte-fusible 8 représentée dans la figure 8 est particulièrement intéressante dans le cas où les fusibles 13 installés sur la barrette 10 sont destinés à être reliés électriquement à une même borne d'une source de courant. Dans ce cas, pour relier entre elles toutes les parties de connexion 2b de la barrette 10, il n'est plus nécessaire de prévoir une piste de puissance sur la carte à circuit imprimé sur laquelle la barrette 10 est destinée à être montée, et il suffit de connecter l'une des parties de connexion 2b de la barrette au circuit imprimé.The embodiment of the strip 10 of fuse holder modules 8 shown in Figure 8 is particularly interesting in the case where the fuses 13 installed on the strip 10 are intended to be connected electrically at the same terminal of a current source. In that case, to connect together all the connection parts 2b of the strip 10, it no longer need to provide a power track on the circuit board printed on which the bar 10 is intended to be mounted, and it suffices to connect one of the connection parts 2b of the strip to the circuit printed.

    Dans les exemples de réalisation décrits ci-dessus, après l'opération de pliage de la bande 1 de métal conducteur, les parties de connexion 2b et 3b des pièces conductrices 2 et 3 s'étendent perpendiculairement au plan de la bande 1 comme cela est notamment visible dans les figures 3 et 5. Dans ce cas, après segmentation de la bande, on obtient des modules porte-fusible 8 ou des barrettes 10 de modules porte-fusible 8 sous la forme de composants électriques destinés à être plantés dans des trous métallisés d'une carte à circuit imprimé, comme la carte 22 partiellement représentée en traits mixtes dans la figure 5. Toutefois, si on le désire, les deux parties de connexion 2b et 3b peuvent être cintrées comme cela est représenté en traits mixtes dans la figure 3 pour la partie de connexion 2b, de telle façon que l'on obtienne, après segmentation de la bande, des modules porte-fusible 8 ou des barrettes 10 de modules porte-fusible 8 sous la forme de composants électriques à montage en surface (composants CMS).In the embodiments described above, after the operation for folding the strip 1 of conductive metal, the connection parts 2b and 3b of the conductive parts 2 and 3 extend perpendicular to the plane of the strip 1 as can be seen in particular in FIGS. 3 and 5. In this case, after segmentation of the strip, fuse holder modules are obtained 8 or strips 10 of fuse holder modules 8 in the form of electrical components intended to be planted in metallized holes a printed circuit board, such as card 22 partially shown in phantom in Figure 5. However, if desired, the two parts connection 2b and 3b can be bent as shown in dashed lines in figure 3 for connection part 2b, so that we obtain, after segmentation of the strip, fuse holder modules 8 or strips 10 of fuse holder modules 8 in the form of surface mount electrical components (SMD components).

    Il est du reste bien entendu que les modes de réalisation de l'invention qui ont été décrits ci-dessus ont été donnés à titre d'exemple purement indicatif et nullement non limitatif, et que de nombreuses modifications peuvent être apportées par l'homme de l'art sans pour autant sortir du cadre de l'invention. C'est ainsi notamment que l'opération de mise en place des fusibles 13 dans les modules porte-fusible 8 (poste III) et l'opération de segmentation de la bande 1 (poste IV) ne sont pas nécessairement effectuées sur la même chaíne de production que celle qui effectue le pliage de la bande 1 (poste I) et le moulage des supports 7 (poste II). En effet, après l'opération de moulage, la bande 1 munie des supports 7 pourrait être par exemple enroulée sous la forme d'une galette et temporairement stockée sous cette forme.It is, of course, moreover that the embodiments of the invention which have been described above have been given by way of example purely indicative and in no way limitative, and that many modifications can be made by those skilled in the art without, however, depart from the scope of the invention. This is how the operation of installation of fuses 13 in fuse holder modules 8 (station III) and the band 1 segmentation operation (item IV) is not necessarily carried out on the same production line as that which performs the folding of the strip 1 (station I) and the molding of the supports 7 (station II). Indeed, after the molding operation, the strip 1 provided with the supports 7 could for example be rolled up in the form of a pancake and temporarily stored in this form.
