Abstract
Description
La présente invention concerne un condensateur å diélectrique film plastique (1) comportant deux électrodes de sortie (2) pourvues de conducteurs (33 aptes à etre soudés sur circuits imprimés.The present invention relates to a plastic film dielectric capacitor (1) comprising two output electrodes (2) provided with conductors (33 capable of being soldered on printed circuits.
Dans les dispositifs connus de ce genre, la température à laquelle est soumis le diélectrique durant l'opération de soudure directe sur circuit imprimé est telle que les diélectriques film plastique ne peuvent être utilisés pour ce type de soudure sans etre détruits.In known devices of this kind, the temperature to which the dielectric is subjected during the direct soldering operation on a printed circuit is such that the plastic film dielectrics cannot be used for this type of soldering without being destroyed.
Pour être soudés sur circuits imprimés sans être détruits par le passage en température, les condensateurs à diélectrique film plastique doivent avoir leur élement capacitif protégé par un enrobage isolant (boitier, résine époxy, surmoulage, ruban adhésif, etc...) et les deux électrodes de sortie de celui-ci reçoivent des fils conducteurs qui seront soudés en travers de trous percés sur le circuit imprimé qui les porte.To be soldered on printed circuits without being destroyed by the passage in temperature, the plastic film dielectric capacitors must have their capacitive element protected by an insulating coating (case, epoxy resin, overmolding, adhesive tape, etc ...) and both its output electrodes receive conductive wires which will be soldered through holes drilled on the printed circuit which carries them.
La présente invention se propose de remédier à ces inconvénients et, pour ce faire, elle a pour objet un condensateur à diélectrique film plastique qui se caractérise en ce que les conducteurs (3) sont constitués par deux pièces métalliques recouvrant les électrodes de sortie (2) et reliées entre elles par l'intermédiaire d'un matériau de protection (4) lequel enveloppe complètement l'élement capacitif (1).The present invention proposes to remedy these drawbacks and, to do this, it relates to a plastic film dielectric capacitor which is characterized in that the conductors (3) consist of two metal parts covering the output electrodes (2 ) and interconnected by means of a protective material (4) which completely envelops the capacitive element (1).
Grâce à cette disposition, il n'est plus nécessaire de percer des trous dans le circuit imprimé pour recevoir les fils conducteurs ni de positionner les fils conducteurs dans les trous. Le condensateur.Thanks to this arrangement, it is no longer necessary to drill holes in the printed circuit to receive the conductive wires or to position the conductive wires in the holes. The capacitor.
peut etre soudé sur le circuit par report à plat grâce à ces deux conducteurs (3).can be soldered on the circuit by flat transfer thanks to these two conductors (3).
De préférence les pièces métalliques (3) qui font office de conducteurs sont constituées de profilé à section en U dont les branches sont tournées l'une vers l'autre.Preferably, the metal parts (3) which act as conductors are made up of a U-shaped section whose branches are turned towards each other.
Selon un mode particulier de réalisation les deux pièces métalliques (3) faisant office de conducteurs peuvent recevoir par soudure des fils soudés sur chacune d'elles soit axialement soit radialement.According to a particular embodiment, the two metal parts (3) acting as conductors can receive by welding welded wires on each of them either axially or radially.
On obtient ainsi un condensateur à fils de sorties axiales ou radiales plus économique à fabriquer que l'état de l'art.A capacitor with axial or radial output leads is thus obtained which is more economical to manufacture than the state of the art.
Un mode d'exécution de la présente invention sera décrit ci-après à titre d'exemple nullement limitatif en référence aux dessins annexes dans lesquels la figure 1 est une vue en coupe selon ligne I I de la figure 3 d'un condensateur conforme à l'invention la figure 2 est une vue en coupe selon la ligne II Il de la figure
I la figure 3 est une vue de dessus du condensateur visible sur la figure 1 la figure 4 est une vue analogue à la figure 2 montrant un condensateur bobiné.An embodiment of the present invention will be described below by way of nonlimiting example with reference to the accompanying drawings in which Figure 1 is a sectional view along line II of Figure 3 of a capacitor according to l invention 2 is a sectional view along line II II of the figure
I Figure 3 is a top view of the capacitor visible in Figure 1 Figure 4 is a view similar to Figure 2 showing a wound capacitor.
)Telle qu'elle est représentée sur les dessins annexés, l:invention comprend un élement capacitif (1), la liaison entre les couches est assurée selon l'état de l'art par projection de grains de métal en fusion (schopage) (2), cette projection constitue les deux électrodes de sortie de l'élement capacitif sur lesquelles on rapporte par soudure électrique ou collage par colle conductrice les deux conducteurs constitués par les pièces métalliques à profil en "U" (3), le matériau d'enrobage (4) isole et protège complètement la partie active de 1 'élement capacitif.) As shown in the accompanying drawings, the invention comprises a capacitive element (1), the connection between the layers is ensured according to the state of the art by projection of grains of molten metal (schopage) ( 2), this projection constitutes the two output electrodes of the capacitive element on which the two conductors made up of metal parts with a "U" profile (3), the coating (4) completely isolates and protects the active part of the capacitive element.
Les deux conducteurs métalliques (3) sont rapportés par soudure elec- trique ou par colle conductrices contre les deux électrodes de sortie (2). La surépaisseur apportée par ces deux conducteurs métalliques est mise à profit pour réaliser un enrobage de l'élement capacitif (1) à l'aide d'un matériau (4) qui viendra le protéger jusqu'au niveau supérieur de l'épaisseur des deux conducteurs métal- liques. De la même, la longueur de ces deux conducteurs métalliques sera légèrement supérieure à la longueur de l'élement capacitif de manière à créer entre les conducteurs métalliques (3) et l'élement capacitif (î) un espace qui sera occupé par le matériau de protection. The two metallic conductors (3) are attached by electrical welding or by conductive adhesive against the two output electrodes (2). The extra thickness provided by these two metal conductors is used to make a coating of the capacitive element (1) using a material (4) which will protect it up to the upper level of the thickness of the two. metallic conductors. Likewise, the length of these two metallic conductors will be slightly greater than the length of the capacitive element so as to create between the metallic conductors (3) and the capacitive element (î) a space which will be occupied by the material of protection.
