Description

ELEMENT DE FUSIBLE ET SON PROCEDE DE FABRICATION FUSE ELEMENT AND MANUFACTURING METHOD THEREOF
La présente invention se rapporte à la technologie des fusibles. Elle concerne, plus particulièrement, un élément de fusible plat - ou en plaquette - destiné, notamment, à réagir à des surcharges de courant faibles mais de longue durée. L'invention concerne aussi un procédé de fabrication d'un tel élément de fusible.The present invention relates to fuse technology. It relates, more particularly, to a flat - or blown fuse element - intended, in particular, to react to low current overloads but of long duration. The invention also relates to a method of manufacturing such a fuse element.
Il est connu, pour réaliser ce type de fusible, de déposer une parcelle d'un métal à bas point de fusion, tel que l'étain, désignée par l'expression "point M", au centre d'un ruban d'argent qui réagit, de manière classique aux fortes surcharges de courant (courts-circuits) mais reste insensible aux faibles surcharges de longue durée.To make this type of fuse, it is known to deposit a piece of a metal with a low melting point, such as tin, designated by the expression "point M", in the center of a silver ribbon. which reacts, in a traditional way to strong current overloads (short-circuits) but remains insensitive to weak overloads of long duration.
Lorsqu'un courant de faible surcharge circule dans le ruban d'argent pendant une durée importante, sa température s'élève progressivement jusqu'à faire fondre la parcelle d'étain. L'alliage de l'argent et de l'étain produit un eutectique ayant un point de fusion beaucoup plus faible que l'argent mais une résistance électrique suffisante pour provoquer la fusion du ruban à cet endroit. Typiquement, cette structure "point M" permet que la fusion intervienne à une température de 200 à 300 °C, alors que la température de fusion normale de l'argent est de 962 °C.When a current of low overcharge flows in the silver ribbon for a long time, its temperature rises gradually until the tin plot melts. The alloy of silver and tin produces an eutectic having a melting point much lower than silver but an electrical resistance sufficient to cause the melting of the ribbon there. Typically, this "M-point" structure allows the melting to take place at a temperature of 200 to 300 ° C., while the normal silver melting temperature is 962 ° C.
Les documents CH 587 559, US 4 134 094 et GB 2 120 027, par exemple, décrivent des réalisations de ce type.The documents CH 587 559, US 4,134,094 and GB 2,120,027, for example, describe embodiments of this type.
La présente invention a pour but de fournir une structure d'élément de fusible en plaquette qui, notamment, améliore l'efficacité de l'effet du "point M" et simplifie fortement sa fabrication.The object of the present invention is to provide a blown fuse element structure which, in particular, improves the effectiveness of the "M point" effect and greatly simplifies its manufacture.
Pour atteindre ce but, l'élément de fusible selon l'invention est constitué d'une plaquette comportant au moins trois parties coplanaires et de même épaisseur réunies par soudage, à savoir: - une partie métallique centrale comportant une portion à point de fusion élevé et une portion à bas point de fusion noyée dans la portion à point de fusion élevé, etTo achieve this object, the fuse element according to the invention consists of a plate comprising at least three coplanar parts and of the same thickness joined by welding, namely: a central metal part comprising a portion with a high melting point and a portion with a low melting point embedded in the portion with a high melting point, and
- deux parties métalliques latérales à point de fusion élevé. II peut être avantageux d'adopter une structure dans laquelle la plaquette comporte, en série, une pluralité de parties centrales disposées chacune entre deux parties latérales.- two lateral metal parts with high melting point. It may be advantageous to adopt a structure in which the plate comprises, in series, a plurality of central parts each arranged between two lateral parts.
Dans une première forme de réalisation avantageuse, la partie centrale est constituée d'un noyau à bas point de fusion et d'une gaine à point de fusion élevé entourant le noyau.In a first advantageous embodiment, the central part consists of a core with low melting point and a sheath with high melting point surrounding the core.
Dans une deuxième forme de réalisation avantageuse, la partie centrale est constituée d'un faisceau de brins à bas point de fusion et d'une matrice à point de fusion élevée entourant les brins.In a second advantageous embodiment, the central part consists of a bundle of strands with a low melting point and a matrix with a high melting point surrounding the strands.
L'élément de fusible selon l'invention comporte encore les principales caractéristiques suivantes:The fuse element according to the invention also has the following main characteristics:
- la portion à bas point de fusion de la partie centrale comporte essentiellement de l'étain;- the portion with a low melting point of the central part essentially comprises tin;
- la portion à bas point de fusion est un alliage étain-argent ou étain- zinc comprenant de 80 à 98% d'étain; - la portion à bas point de fusion occupe de 15 à 60% en poids de la partie centrale;the portion with a low melting point is a tin-silver or tin-zinc alloy comprising from 80 to 98% tin; - the portion with low melting point occupies 15 to 60% by weight of the central part;
- la portion à point de fusion élevé de la partie centrale est en cuivre ou en argent;- the high melting point portion of the central part is made of copper or silver;
- les parties latérales sont en cuivre ou en argent; et - de façon particulièrement avantageuse, les parties latérales sont en cuivre et la portion à point de fusion élevé de la partie centrale est en argent.- the side parts are made of copper or silver; and - particularly advantageously, the lateral parts are made of copper and the high melting point portion of the central part is made of silver.
Le procédé selon l'invention est caractérisé en ce que les parties de l'élément de fusible sont formées et réunies par laminage. De manière avantageuse, la partie centrale peut soit provenir d'un fil gainé possédant une âme à bas point de fusion entourée d'une gaine à point de fusion élevé, soit provenir d'un fil composite formé d'un faisceau de brins à bas point de fusion noyés dans une matrice à point de fusion élevé. D'autres caractéristiques et avantages de la présente invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel :The method according to the invention is characterized in that the parts of the fuse element are formed and joined by rolling. Advantageously, the central part can either come from a sheathed wire having a core with low melting point surrounded by a sheath with high melting point, or come from a composite wire formed by a bundle of strands at low melting point embedded in a high melting point matrix. Other characteristics and advantages of the present invention will emerge from the description which follows, given with reference to the appended drawing, in which:
- les figures 1 et 2 représentent deux modes de réalisation de l'élément de fusible, etFIGS. 1 and 2 represent two embodiments of the fuse element, and
- la figure 3 représente un élément de fusible à plusieurs parties centrales.- Figure 3 shows a fuse element with several central parts.
On se référera, tout d'abord, à la figure 1 qui montre, en 10, un élément de fusible se présentant sous la forme d'une mince plaquette allongée ayant, typiquement, une longueur de 10 à 100 mm, une largeur de 2 à 15 mm et une épaisseur de 0.02 à 0.5 mm. Cette plaquette comporte généralement, de manière classique, des encoches ou des trous qui en réduisent la section de façon à optimiser la fonction court-circuit du fusible.First of all, reference is made to FIG. 1 which shows, at 10, a fuse element in the form of a thin elongated plate having, typically, a length of 10 to 100 mm, a width of 2 to 15 mm and a thickness of 0.02 to 0.5 mm. This plate generally comprises, in a conventional manner, notches or holes which reduce the section thereof so as to optimize the short-circuit function of the fuse.
La plaquette 10, découpée dans une bande, comporte trois parties coplanaires, juxtaposées dans le sens de sa longueur et réunies par soudage, à savoir: - une partie centrale 12 ayant, typiquement, une longueur de 2 à 10 mm, etThe plate 10, cut from a strip, has three coplanar parts, juxtaposed in the direction of its length and joined by welding, namely: - a central part 12 having, typically, a length of 2 to 10 mm, and
- deux parties latérales 14.- two side parts 14.
Les parties latérales 14 sont réalisées en un métal présentant une bonne conductivité électrique et un point de fusion élevé, tel que le cuivre et l'argent. Dans le mode de réalisation de la figure 1 , la partie centrale 12 est constituée d'un noyau 16, à section grossièrement rectangulaire, et d'une gaine 18 entourant le noyau. Celui-ci occupe 15 à 60 % en poids de la partie centrale 12, la gaine 18 en occupant donc 40 à 85 %. Le noyau 16 est essentiellement formé d'un métal à bas point de fusion, avantageusement de l'étain. A titre indicatif, il peut s'agir d'un alliage étain- argent ou étain-zinc comprenant de 80 à 98% d'étain.The side parts 14 are made of a metal having good electrical conductivity and a high melting point, such as copper and silver. In the embodiment of FIG. 1, the central part 12 consists of a core 16, of roughly rectangular section, and of a sheath 18 surrounding the core. This occupies 15 to 60% by weight of the central part 12, the sheath 18 therefore occupying 40 to 85%. The core 16 is essentially formed from a metal with a low melting point, advantageously tin. As an indication, it can be a tin-silver or tin-zinc alloy comprising from 80 to 98% tin.
La gaine 18 est essentiellement formée d'un métal présentant une bonne conductivité électrique et un point de fusion élevé, tel que le cuivre et l'argent.The sheath 18 is essentially formed from a metal having good electrical conductivity and a high melting point, such as copper and silver.
Selon le mode de réalisation représenté à la figure 2, la plaquette 10 comporte toujours une partie centrale 12 et deux parties latérales 14. Celles-ci sont identiques à celles de la réalisation de la figure 1 , mais la partie centraleAccording to the embodiment shown in Figure 2, the plate 10 always has a central portion 12 and two side portions 14. These are identical to those of the embodiment of Figure 1, but the central portion
12 est constituée d'un faisceau de brins 20 à bas point de fusion répartis dans une matrice 22 à point de fusion élevé.12 consists of a bundle of strands 20 with a low melting point distributed in a matrix 22 with a high melting point.
Les brins 20 occupent 15 à 60 % en poids de la partie centrale 12, la matrice 22 en occupant donc 40 à 85 %.The strands 20 occupy 15 to 60% by weight of the central part 12, the matrix 22 therefore occupying 40 to 85%.
Les brins 20 sont de même nature que le noyau 16 et la matrice 22 de même nature que la gaine 18. Ainsi est réalisé, selon deux modes différents illustrés par les figures 1 et 2, un élément de fusible dans lequel le "point M" est intimement intégré dans sa portion en cuivre ou argent sensible aux fortes surcharges de courant.The strands 20 are of the same nature as the core 16 and the matrix 22 of the same nature as the sheath 18. Thus is produced, according to two different modes illustrated by Figures 1 and 2, a fuse element in which the "point M" is intimately integrated into its copper or silver portion sensitive to strong current overloads.
On notera que, selon un mode de réalisation particulièrement avantageux de l'invention, les deux parties latérales sont en cuivre, alors que la portion à point de fusion élevé de la partie centrale est en argentIt will be noted that, according to a particularly advantageous embodiment of the invention, the two lateral parts are made of copper, while the portion with a high melting point of the central part is made of silver
Grâce à cette structure qui augmente considérablement les surfaces de contact entre l'étain et l'argent ou le cuivre, la formation de l'eutectique à bas point de fusion intervient plus rapidement que dans le cas des structures de l'art antérieur, utilisant une parcelle d'étain simplement déposée sur le fusible. L'efficacité du "point M" s'en trouve fortement améliorée. La quantité de matière nécessaire est donc réduite, ce qui abaisse le prix de revient du fusible. De plus, l'élément sensible ne comportant plus la bosse que constitue la parcelle d'étain, il est plus facile à manipuler. La fabrication de l'élément de fusible décrit ci-dessus fait appel aux techniques de laminage, bien connues de l'homme de métier. On se contentera donc d'indiquer que l'on part de deux bandes de cuivre ou d'argent destinées à constituer les parties latérales 14 et, pour réaliser la partie centrale 12, soit d'un fil gainé possédant une âme en étain entourée d'une gaine d'argent ou de cuivre, soit d'un fil composite formé d'un faisceau de brins d'étain noyés dans une matrice d'argent ou de cuivre. Le laminage permet alors de souder les deux bandes et le fil en les écrasant puis de les laminer jusqu'à l'épaisseur demandée. La bande qui résulte de ces opérations est finalement découpée dans le sens de sa largeur pour obtenir les plaquettes telles que représentées sur les figures.Thanks to this structure which considerably increases the contact surfaces between tin and silver or copper, the formation of the eutectic at low melting point occurs more quickly than in the case of the structures of the prior art, using a piece of tin simply placed on the fuse. The efficiency of the "M point" is greatly improved. The amount of material required is therefore reduced, which lowers the cost price of the fuse. In addition, the sensitive element no longer comprising the bump that constitutes the parcel of tin, it is easier to handle. The manufacture of the fuse element described above uses rolling techniques, well known to those skilled in the art. It will therefore be sufficient to indicate that one starts from two bands of copper or silver intended to constitute the lateral parts 14 and, to produce the central part 12, either of a sheathed wire having a tin core surrounded by '' a silver or copper sheath, or a composite wire formed of a bundle of strands of tin embedded in a matrix of silver or copper. The rolling then welds the two strips and the wire by crushing them and then laminates them to the required thickness. The strip which results from these operations is finally cut in the width direction to obtain the plates as shown in the figures.
Lorsque la structure laminée comporte du cuivre à l'extérieur et de l'argent à l'intérieur, il est intéressant de noter qu'à leur jonction avec la partie centrale en argent 12, les deux parties latérales en cuivre 14 ont des extrémités convexes. Cela résulte simplement du fait que l'argent de la partie centrale est moins dur que le cuivre ou l'argent des parties latérales. Lors du laminage, celles-ci empiètent donc sur la partie centrale.When the laminated structure has copper on the outside and silver on the inside, it is interesting to note that at their junction with the central silver part 12, the two lateral copper parts 14 have convex ends. . This is simply due to the fact that the silver in the central part is less hard than copper or the silver in the side parts. During rolling, they therefore encroach on the central part.
On se référera, pour terminer, à la figure 3 qui montre une plaquette 10' selon l'invention comportant plusieurs parties centrales 12, au nombre de trois dans le mode de réalisation représenté, insérées chacune entre deux parties latérales 14. Les parties centrales 12 peuvent être constituées soit, comme montré sur la figure 3, d'un noyau 16 et d'une gaine 18 l'entourant soit, comme montré sur la figure 2, d'un faisceau de brins 20 répartis dans une matrice 22. Une telle structure peut être préférée pour certaines applications, notamment du fait qu'elle permet une réponse plus rapide aux surcharges . Finally, reference is made to FIG. 3 which shows a plate 10 ′ according to the invention comprising several central parts 12, three in number in the embodiment shown, each inserted between two lateral parts 14. The central parts 12 may consist either of, as shown in FIG. 3, a core 16 and a sheath 18 surrounding it, or, as shown in FIG. 2, of a bundle of strands 20 distributed in a matrix 22. Such a structure may be preferred for certain applications, in particular because it allows a faster response to overloads.
