Description

L'invention concerne un dispositif à filtre électrique, et plus particulièrement un dispositif comprenant une borne électrique qui comporte une partie cylindrique de montage, et un filtre tubulaire cylindrique monté sur cette partie de la borne, ce filtre comportant un contact intérieur qui est relié électriquement à la borne. The invention relates to an electrical filter device, and more particularly to a device comprising an electrical terminal which comprises a cylindrical mounting part, and a cylindrical tubular filter mounted on this part of the terminal, this filter comprising an internal contact which is electrically connected. at the terminal.

Le filtre comporte normalement un contact extérieur qui doit être connecté, par exemple, à une plaque de masse à travers laquelle la borne et le filtre passent, cette connexion servant également souvent au montage mécanique de la borne et du filtre sur la plaque de masse. The filter normally has an external contact which must be connected, for example, to a ground plate through which the terminal and the filter pass, this connection also often serving for the mechanical mounting of the terminal and the filter on the ground plate.

Cependant, étant donné la nature souvent fragile et la faible dimension du filtre, on rencontre fréquemment des difficultés lors du montage de la borne et du filtre d'une manière sûre des points de vue mécanique et électrique, et sans provoquer de détérioration du filtre. However, given the often fragile nature and the small size of the filter, difficulties are frequently encountered when mounting the terminal and the filter in a mechanical and electrical manner, and without causing deterioration of the filter.

L'invention concerne un dispositif du type décrit ci-dessus, caractérisé par le fait qu'il comporte un élément tubulaire de montage, conducteur du courant électrique et comprenant une première partie de diamètre relativement faible, dans laquelle le filtre est logé et qui est reliée électriquement à un contact extérieur de ce filtre, et une seconde partie de diamètre relativement grand, coaxiale à la borne et au filtre et partant de la premiére partie à un point situé au-delà d'une extrémité du filtre. Une matière d'enrobage, électriquement isolante, remplit au moins partiellement l'espace compris entre la seconde partie de l'élément de montage et le filtre. The invention relates to a device of the type described above, characterized in that it comprises a tubular mounting element, conductive of the electric current and comprising a first part of relatively small diameter, in which the filter is housed and which is electrically connected to an external contact of this filter, and a second part of relatively large diameter, coaxial with the terminal and with the filter and starting from the first part at a point situated beyond one end of the filter. An electrically insulating coating material at least partially fills the space between the second part of the mounting element and the filter.

L'élément de montage du dispositif selon l'invention facilite la mise en place de ce dernier dans un trou d'une plaque de masse, alors que la matière d'enrobage rend le dispositif rigide et assure la protection du filtre
L'invention sera décrite plus en détail en regard du dessin annexe à titre d'exemples nullement limitatifs et sur lequel
- la figure 1 est une vue en perspective éclatée du dispositif selon l'invention;
- la figure 2 est une coupe longitudinale du dispositif de la figure 1 assemblé et monté dans un trou d'une plaque de masse ; et
- la figure 3 est une coupe longitudinale d'une variante du dispositif selon l'invention.The mounting element of the device according to the invention facilitates the positioning of the latter in a hole in a ground plate, while the coating material makes the device rigid and protects the filter.
The invention will be described in more detail with reference to the accompanying drawing by way of non-limiting examples and in which
- Figure 1 is an exploded perspective view of the device according to the invention;
- Figure 2 is a longitudinal section of the device of Figure 1 assembled and mounted in a hole in a ground plate; and
- Figure 3 is a longitudinal section of a variant of the device according to the invention.

Le dispositif selon l'invention3 représenté sur la figure 1, comprend une borne électrique 1 se présentant sous la forme d'une broche cylindrique qui comporte, à une extrémité, une première partie 2 de contact, une partie intermédiaire 3 de montage dont le diamètre est inférieur à celui de la première partie 2 de contact, et une seconde partie 4 de contact dont le diamètre est inférieur à celui de la partie 3 de montage et qui est située à l'autre extrémité de la borne. Le dispositif comprend également un filtre tubulaire 5 comportant des contacts intérieur et extérieur (par exemple comme décrit dans le brevet français nO 70/44 195) et un élément tubulaire 6 de montage, conducteur du courant électrique. Le dispositif comporte également, de manière facultative, un adaptateur 7 de borne.L'élément 6 de montage comporte une première partie 8 de diamètre relativement faible et une seconde partie 9 de diamètre relativement grand. Les parties 8 et 9 sont reliées l'une à l'autre par une partie intermédiaire 10 de diamètre moyen, la jonction entre les parties 9 et 10 constituant un épaulement annulaire extérieur 11 tourné vers la partie 8. The device according to the invention3 shown in Figure 1, includes an electrical terminal 1 in the form of a cylindrical pin which comprises, at one end, a first contact part 2, an intermediate mounting part 3 whose diameter is less than that of the first contact part 2, and a second contact part 4 whose diameter is less than that of the mounting part 3 and which is located at the other end of the terminal. The device also comprises a tubular filter 5 comprising interior and exterior contacts (for example as described in French patent no. 70/44 195) and a tubular mounting element 6, conductive of the electric current. The device also optionally includes a terminal adapter 7. The mounting element 6 comprises a first part 8 of relatively small diameter and a second part 9 of relatively large diameter. The parts 8 and 9 are connected to each other by an intermediate part 10 of average diameter, the junction between the parts 9 and 10 constituting an external annular shoulder 11 turned towards the part 8.

Comme représenté sur la figure 2, lors de l'assemblage, le filtre 5 est monté sur la partie 3 de montage de la borne 1 de manière qu'un contact intérieur 12 de ce filtre 5 soit relié électriquement, par exemple soudé, à la partie 3 de montage de la borne 1 et qu'une extrémité du filtre 5 porte contre l'épaulement 13 formé entre les parties 2 et 3 de la borne 1. L'élément 6 de montage est ensuite mis en place sur le filtre 5 qui se loge dans la partie 8 de cet élément 6 de montage, ladite partie 8 étant reliée électriquement, par exemple soudée, à un contact extérieur 14 du filtre 5. L'élément 6 de montage est placé de manière que sa partie 9 soit coaxiale à la borne 1 et au filtre 5 et qu'elle dépasse de l'extrémité adjacente du filtre 5 (comme montré clairement sur la figure 2).Si cela est nécessaire, l'adaptateur 7 est ensuite montre sur la borne 1, comme représenté, cet adaptateur 7 comprenant une partie 15 de contact de diamètre demandé. As shown in FIG. 2, during assembly, the filter 5 is mounted on the mounting part 3 of the terminal 1 so that an internal contact 12 of this filter 5 is electrically connected, for example welded, to the part 3 for mounting the terminal 1 and that one end of the filter 5 bears against the shoulder 13 formed between the parts 2 and 3 of the terminal 1. The mounting element 6 is then placed on the filter 5 which is housed in part 8 of this mounting element 6, said part 8 being electrically connected, for example welded, to an external contact 14 of the filter 5. The mounting element 6 is placed so that its part 9 is coaxial with terminal 1 and to filter 5 and that it protrudes from the adjacent end of filter 5 (as clearly shown in Figure 2). If necessary, the adapter 7 is then shown on terminal 1, as shown, this adapter 7 comprising a contact portion 15 of requested diameter.

L'espace compris entre les parties 9 et 10 de l'élément de montage, d'une part, et le filtre 5, la borne I et, le cas échéant et comme représenté, l'adaptateur 7, d'autre part, est ensuite rempli au moins partiellement d'une matière d'enrobage 16, électriquement isolante qui, lorsqu'elle a durci, rend le dispositif relativement rigide. The space between parts 9 and 10 of the mounting element, on the one hand, and the filter 5, the terminal I and, if necessary and as shown, the adapter 7, on the other hand, is then at least partially filled with an electrically insulating coating material 16 which, when it has hardened, makes the device relatively rigid.

Le dispositif peut ensuite être monté dans un trou 100 réalisé, par exemple, dans une plaque conductrice 101 de masse, la partie 10 de l'élément 6 de montage se logeant dans le trou 100 et l'épaulement 11 de cet élément 6 de montage portant contre une surface de la plaque 101. L'élément 6 de montage peut être relié à la plaque 101 par une soudure. Cet élément 6 de montage assure alors la connexion électrique nécessaire entre le contact extérieur 14 du filtre 5 et la plaque 101 de masse.  The device can then be mounted in a hole 100 made, for example, in a conductive plate 101 of mass, the part 10 of the mounting element 6 being housed in the hole 100 and the shoulder 11 of this mounting element 6 bearing against a surface of the plate 101. The mounting element 6 can be connected to the plate 101 by a weld. This mounting element 6 then provides the necessary electrical connection between the external contact 14 of the filter 5 and the ground plate 101.

La figure 3 représente une variante du dispositif selon l'invention, analogue à la forme de réalisation montrée sur les figures 1 et 2. Les éléments communs aux deux formes de réalisation portent les mêmes références numériques. Les différences essentielles entre les deux formes de réalisation sont que la borne ne comporte que deux parties 2 et 4, la partie 4 de contact constituant également la partie de montage du filtre 5. L'élément 6 de montage comporte une autre seconde partie 17 de diamètre relativement grand, partant de la première partie 8, mais en sens opposé à celui de la première seconde partie citée 9. Cette autre seconde partie 17 est également remplie, au moins partiellement, de matière 16 d'enrobage. La jonction entre la seconde partie 17 et la première partie 8 de l'élément 6 de montage est réalisée de manière à former un rebord annulaire extérieur 18 au moyen duquel le dispositif peut être fixé dans un trou d'une plaque de masse (non représentée), comme montré pour la forme de réalisation représentée sur les figures 1 et 2. FIG. 3 represents a variant of the device according to the invention, analogous to the embodiment shown in FIGS. 1 and 2. The elements common to the two embodiments have the same numerical references. The essential differences between the two embodiments are that the terminal has only two parts 2 and 4, the contact part 4 also constituting the mounting part of the filter 5. The mounting element 6 has another second part 17 of relatively large diameter, starting from the first part 8, but in opposite direction to that of the first second part cited 9. This other second part 17 is also filled, at least partially, with coating material 16. The junction between the second part 17 and the first part 8 of the mounting element 6 is produced so as to form an external annular rim 18 by means of which the device can be fixed in a hole in a ground plate (not shown ), as shown for the embodiment shown in Figures 1 and 2.

Il va de soi que de nombreuses modifications peuvent être apportées au dispositif décrit et représenté sans sortir du cadre de l'invention.  It goes without saying that numerous modifications can be made to the device described and shown without departing from the scope of the invention.
