Description
COMPOSANT ELECTRIQUE COMPORTANT DES FILS DE RACCORDEMENT EN FORME DEELECTRICAL COMPONENT HAVING CONNECTING WIRES IN THE FORM OF
PIEDS L'invention se situe dans le domaine de l'assemblage de circuits imprimés comportant des composants électriques et peut être utilisée pour le mode de réalisation nécessaire à cet effet des composants qui ont une forme cylindrique et qui sont munis d'au moins deux fils de raccordement; des composants correspondants peuvent être par exemple des résistances, des condensateurs et FEET The invention is in the field of assembling printed circuits comprising electrical components and can be used for the embodiment necessary for this purpose of components which have a cylindrical shape and which are provided with at least two wires connection; corresponding components can be for example resistors, capacitors and
des parasurtensions remplis de gaz.surge arresters filled with gas.
Lorsque l'on équipe des plaquettes à circuits imprimés on se dispense depuis peu de mettre les fils de raccordement des composants électriques à braser aux pistes conductrices d'une plaquette à circuits imprimés dans des trous des pistes conductrices, mais on pose les composants munis de raccords appropriés sur les pistes conductrices vierges. Afin de pouvoir monter de manière stable aussi des composants cylindriques comportant deux fils de raccordement axialement en saillie sur des plaquettes à circuits imprimés, il est déjà connu de couder les fils de raccordement de 180 en direction du composant dans un plan commun de telle manière que, lorsque l'on utilise le composant dans un circuit à couche, le vecteur poids du composant passe par le centre du plan délimité par les extrémités des fils de raccordement (DE 25 08 702 A). Pour des composants cylindriques relativement longs, les tronçons des fils de raccordement qui forment chacun un pied ont aussi une longueur relativement grande. A partir d'un composant électrique cylindrique comportant deux fils métalliques de raccordement montés sur les côtés frontaux et constitués d'un fil métallique de section transversale circulaire, les fils métalliques de raccordement étant coudés de manière que leurs extrémités libres s'étendant parallèlement l'une à l'autre forment deux côtés opposés d'un rectangle et ainsi des pieds permettant de placer le composant à l'horizontale de manière stable, I'invention vise à assurer par des pieds aussi courts que possible la stabilité du composant When equipping printed circuit boards, it has recently been dispensed with putting the connection wires of the electrical components to be soldered to the conductive tracks of a printed circuit board in holes in the conductive tracks, but the components fitted with appropriate fittings on the blank conductor tracks. In order to be able to stably mount also cylindrical components having two axially projecting connection wires on printed circuit boards, it is already known to bend the connection wires 180 in the direction of the component in a common plane so that , when the component is used in a layer circuit, the weight vector of the component passes through the center of the plane delimited by the ends of the connection wires (DE 25 08 702 A). For relatively long cylindrical components, the sections of the connecting wires which each form a foot are also relatively long. From a cylindrical electrical component comprising two metallic connection wires mounted on the front sides and constituted by a metallic wire of circular cross section, the metallic connection wires being bent so that their free ends extending parallel to the one to the other form two opposite sides of a rectangle and thus feet allowing the component to be placed horizontally in a stable manner, the invention aims to ensure by the feet as short as possible the stability of the component
indépendamment de sa longueur.regardless of its length.
On y parvient, suivant l'invention, par le fait que les zones coudées des fils métalliques de raccordement s'étendent parallèlement aux faces frontales du composant et que les extrémités libres sont aplaties et ont une surface de According to the invention, this is achieved by the fact that the bent zones of the metallic connection wires extend parallel to the front faces of the component and that the free ends are flattened and have a surface of
support d'environ 1 à 10 mm2.support of approximately 1 to 10 mm2.
En donnant ce genre de forme aux fils de raccordement, les pieds peuvent être placés sur les faces frontales du composant, donc dans les zones dans By giving this kind of shape to the connection wires, the feet can be placed on the front faces of the component, therefore in the areas in
lesquelles les fils de raccordement sont de toute façon raccordés au composant. which the connection wires are in any case connected to the component.
L'aplatissement des extrémités libres des fils de raccordement habituellement de section transversale circulaire, qui peut être obtenu par exemple en les soumettant à un écrasement, sert à agrandir la surface de contact et à améliorer la résistance mécanique de la jonction par brasage recherchée entre les fils de The flattening of the free ends of the connection wires, usually of circular cross section, which can be obtained for example by subjecting them to crushing, serves to enlarge the contact surface and to improve the mechanical resistance of the desired solder junction between the son of
raccordement et la plaquette à circuits imprimés. connection and printed circuit board.
Un exemple de réalisation du nouveau composant est représenté aux figures 1 à 3. Au dessin: les figures 1 et 2 sont deux vues de ce que l'on appelle un "parasurtenion sous verre", donc d'un parasurtension comportant un isolant en verre, deux électrodes et deux fils de raccordement, et la figure 3 représente une partie d'un fil de raccordement, en soi de section An exemplary embodiment of the new component is shown in FIGS. 1 to 3. In the drawing: FIGS. 1 and 2 are two views of what is called a “surge protector under glass”, therefore of a surge protector comprising a glass insulator , two electrodes and two connection wires, and FIG. 3 represents a part of a connection wire, per se of section
transversale circulaire, aplati dans la zone du pied. transverse circular, flattened in the foot area.
Les figures 1 et 2 représentent ce que l'on appelle un parasurtension 1 sous verre qui est constitué d'un isolant 2 en verre, des deux électrodes 3 et 4 et des fils 5 et 6 de raccordement et qui est disposé sur une plaquette 11 à l'aide des fils 5 et 6 de raccordement. A cet effet, les deux fils 5 et 6 de raccordement qui sont soudés axialement aux électrodes 3 et 4 et qui sont en cuivre facile à couder, sont coudés deux fois. Les fils de raccordement sont d'abord coudés dans la même direction, perpendiculairement à l'axe du parasurtension 1 sous verre, si bien que les fils de raccordement se trouvent dans des plans s'étendant parallèlement aux faces frontales de l'isolant. Dans ces plans, les fils de raccordement sont de nouveau coudés, si bien que l'on obtient dans ce plan deux tronçons de fils qui font un angle a entre eux. Le tronçon 7 du fil 6 de raccordement représente en quelque sorte une branche supérieure et le tronçon 9 du fil 6 de raccordement une branche inférieure, de même, le fil 5 de Figures 1 and 2 show what is called a surge protector 1 under glass which consists of an insulator 2 made of glass, two electrodes 3 and 4 and connecting wires 5 and 6 and which is arranged on a plate 11 using connection wires 5 and 6. For this purpose, the two connecting wires 5 and 6 which are welded axially to the electrodes 3 and 4 and which are made of copper which is easy to bend, are bent twice. The connection wires are first bent in the same direction, perpendicular to the axis of the surge arrester 1 under glass, so that the connection wires are in planes extending parallel to the front faces of the insulation. In these planes, the connecting wires are bent again, so that in this plane two sections of wires are obtained which form an angle a between them. The section 7 of the connecting wire 6 somehow represents an upper branch and the section 9 of the connecting wire 6 a lower branch, likewise, the wire 5
raccordement comporte une branche 8 supérieure et une branche 10 inférieure. connection comprises an upper branch 8 and a lower branch 10.
Les deux branches 9 et 10 supérieures, qui forment en même temps les "pieds" au sens de l'invention, s'étendent parallèlement l'un a l'autre et forment ainsi deux côtés opposés d'un rectangle au-dessus duquel est posé le parasurtension 1 sous verre constitué de l'isolant 2 et des électrodes 3 et 4. Le centre de gravité du limiteur projeté sur la plaquette 11 se trouve à l'intérieur de la surface The two upper arms 9 and 10, which at the same time form the "feet" within the meaning of the invention, extend parallel to each other and thus form two opposite sides of a rectangle above which is placed the surge protector 1 under glass consisting of the insulator 2 and the electrodes 3 and 4. The center of gravity of the limiter projected on the wafer 11 is located inside the surface
rectangulaire délimitée par les branches 9 et 10 inférieures. rectangular bounded by the lower branches 9 and 10.
Suivant la figure 3, chaque fil de raccordement est muni a son extrémité 31 libre d'un aplatissement 32, afin d'assurer une surface de brasage suffisamment grande lorsqu'on le pose sur une piste conductrice de la plaquette 11. Cet aplatissement 32 et la longueur des branches 9 et 10 inférieures peuvent être choisis de manière que la surface de support soit d'au moins 1 mm2, According to FIG. 3, each connection wire is provided at its free end 31 with a flattening 32, in order to ensure a sufficiently large soldering surface when it is placed on a conductive track of the wafer 11. This flattening 32 and the length of the lower branches 9 and 10 can be chosen so that the support surface is at least 1 mm2,
avantageusement d'environ 4 mmn.preferably about 4 mmn.
