Description
<Desc/Clms Page number 1>
Filtre antiparasites La présente invention a pour objet un filtre antiparasites. Ce filtre est caractérisé par le fait que son boîtier est blindé.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution ,de l'objet de l'invention.
La fig. 1 est une vue en perspective du filtre. La fig. 2 est une coupe du boîtier du filtre ; et, la fig. 3 représente le schéma électrique de ce filtre.
Le filtre représenté comprend deux conducteurs principaux 1 et 2 portant chacun une cosse d'entrée 3, et une cosse de sortie 4. Deux bobines 5, avec noyaux, de même que deux bobines 6, sans fer, sont montées chacune en série sur les conducteurs 1 et 2 respectivement. Ces deux conducteurs sont court- circuités par deux condensateurs 8 montés en série. Leur point commun 9 est relié par un condensateur 10 à la masse du boîtier désignée par 11.
Les différents organes de ce filtre, à l'exception des extrémités des conducteurs 1 et 2 portant les cosses sont enfermés dans un boîtier cubique comprenant une enveloppe extérieure 12 en bakélite, une enveloppe intermédiaire métallique 13 constituant l'a masse du boîtier à laquelle est relié le condensateur 10, et une enveloppe intérieure 1.4, isolante, en matière plastique par exemple. L'enveloppe métallique 13 est reliée à une barrette métallique 15 destinée à être fixée à la masse de l'appareil sur lequel est monté le filtre.
L'expérience a montré que, grâce au blindage que constitue l'enveloppe métallique 13 du boîtier, et grâce à l'emploi des bobines sans fer 6, le filtre atteint une haute efficacité tout en étant de dimensions très réduites. C'est ainsi que le boîtier du filtre représenté est un cube d'environ 25 rnm d'arête.

Interference filter The present invention relates to a interference filter. This filter is characterized by the fact that its housing is shielded.
The appended drawing represents, by way of example, an embodiment of the subject of the invention.
Fig. 1 is a perspective view of the filter. Fig. 2 is a section through the filter housing; and, FIG. 3 shows the electrical diagram of this filter.
The filter shown comprises two main conductors 1 and 2 each carrying an input terminal 3, and an output terminal 4. Two coils 5, with cores, as well as two coils 6, without iron, are each mounted in series on the conductors 1 and 2 respectively. These two conductors are short-circuited by two capacitors 8 connected in series. Their common point 9 is connected by a capacitor 10 to the mass of the case designated by 11.
The various members of this filter, with the exception of the ends of the conductors 1 and 2 carrying the lugs are enclosed in a cubic box comprising an outer shell 12 in bakelite, an intermediate metal shell 13 constituting the mass of the box to which is connected the capacitor 10, and an inner envelope 1.4, insulating, in plastic for example. The metal casing 13 is connected to a metal bar 15 intended to be fixed to the ground of the device on which the filter is mounted.
Experience has shown that, thanks to the shielding formed by the metal casing 13 of the housing, and thanks to the use of iron-free coils 6, the filter achieves high efficiency while being of very small dimensions. Thus, the filter housing shown is a cube of about 25 mm edge.
