Description
Le brevet principal revendique un dispositif destiné à réaliser si multandment l'étanchéitd et l'ancrage d'un cabale électrique,par exemple sur une armoire, un coffret, ou analogue, qu'il pénètre, constitué par un corps tubulaire dans lequel passe le cable et qui est en deux parties venant se visser l'une sur l'autre, I'une comportant un moyen tel que garn iture d'étanchéité, l'autre un moyen tel que douille à fentes, destiné à réaliser l'ancrage du cabale, ce dispositif étant caractérisé en ce que la douille d'ancrage à fentes et la garniture d'Stanchéité sont disposées en face l'une de l'autre, et au serrage, sont en contact l'une avec l'autre, ce qui, lors du serrage par vissage l'une sur l'autre des deux parties du corps tubulaire, renforce l'action exercée sur la garniture d'étanchéité et sur la douille d'ancrage par l'action réciproque de l'une sur l'autre. The main patent claims a device intended to achieve so multandment the sealing and anchoring of an electric cabal, for example on a cabinet, a box, or the like, which it penetrates, constituted by a tubular body in which the cable and which is in two parts coming to be screwed one on the other, one comprising a means such as a seal, the other a means such as a slotted sleeve, intended to anchor the cabale, this device being characterized in that the slotted anchoring sleeve and the sealing gasket are arranged opposite one another, and when clamped, are in contact with each other, this which, during tightening by screwing one on the other of the two parts of the tubular body, reinforces the action exerted on the sealing gasket and on the anchoring sleeve by the reciprocal action of one on the 'other.
Conformément à la prdsente addition, la partie du corps recevant la bague d'étanchéité est prolongée par une partie conique dans laquelle vient se loger une bague métallique, de forme correspondante, éventuellement fendue. In accordance with the present addition, the part of the body receiving the sealing ring is extended by a conical part in which is housed a metal ring, of corresponding shape, possibly split.
Ces dispositions suivant l'invention permettent,lors du vissage l'une sur l'autre des deux parties du dispositif, de réaliser de façon efficace et sans effort considérable, aussi bien la mise à la masse du blindage du câble qu'un ancrage supplémentaire de ce dernier. These arrangements according to the invention allow, when screwing one on the other of the two parts of the device, to achieve effectively and without considerable effort, both the grounding of the cable shielding and an additional anchoring of the last.
On a décrit ci-après, uniquement à titre d'exemple, une forme de réalisation du dispositif suivant la présente addition, toutes autres formes, proportions et dispositions, pouvant etre adoptées sans sortir du cadre de cette addition. We have described below, only by way of example, an embodiment of the device according to this addition, all other shapes, proportions and arrangements, which can be adopted without departing from the scope of this addition.
Au cours de cette description, on se réfère au dessin ci-joint sur lequel - la Fig. 1 montre, partie en coupe longitudinale, partie en vue extérieure,
untel dispositif, - les Fig. 2 et 3 montrent, l'une en bout, l'autre partie en coupe, partie en
vue extérieure, la bague de mise à la masse et d'ancrage supplémentaire,
dans une première forme de réalisation, - les Fig. 4 et 5 sont des vues, analogues aux Fig. 2 et 3, d'une autre forme
de réalisation de cette bague. During this description, reference is made to the attached drawing in which - FIG. 1 watch, part in longitudinal section, part in external view,
such and such a device, - Figs. 2 and 3 show, one at the end, the other part in section, part in
external view, the earthing and additional anchoring ring,
in a first embodiment, - Figs. 4 and 5 are views, similar to FIGS. 2 and 3, of another form
of making this ring.
Comme décrit dans le brevet principal, le dispositif est constitué de deux parties tubulaires A, B, dans lesquelles passe le câble 1 et qui se vissent l'une dans l'autre. Dans la partie B est logée la douille cylindrique d'ancrage d, à fentes d1. La partie A reçoit, par sa portée conique al, la garniture d'étanchéité a disposée en face de la douille fendue d. As described in the main patent, the device consists of two tubular parts A, B, through which the cable 1 passes and which are screwed into one another. In part B is housed the cylindrical anchoring sleeve d, with slots d1. Part A receives, by its conical bearing al, the seal has disposed opposite the split bushing d.
Conformément à la présente addition, la portée conique al se prolonge par une portée conique a2 de conicité différente de celle de la porte al. Dans cette portée conique a2 vient se loger une bague m.étallique e. La conicité de cette bague est légErementdifférentede celle de la portée a2 dans le cas d'un cible armé d'un feuillard ; elle lui est égale dans le cas d'un câble armé d'une tresse. In accordance with the present addition, the tapered seat al is extended by a tapered seat a2 with a different taper than that of the door al. In this conical bearing a2 is housed a metal ring e. The taper of this ring is slightly different from that of the range a2 in the case of a target armed with a strap; it is equal to it in the case of a cable armed with a braid.
La bague e est pleine, comme le montrent les Fig. 2 et 3 dans le cas d'un cabale armé d'une tresse ; dans le cas d'un cible armé d'un feuillard la bague présente, comme le montrent les Fig. 4 et 5, des fentes f radiales, partielles ou totales comme la fente représentée en f . Enfin, la bague e comporte en outre une surface d'appui g sur laquelle vient reposer la garniture d'étanchéité a
La mise à la masse du blindage (feuillard ou tresse) du cible 1 est obtenue par pincement de celui-ci entre la bague métallique e et le crible lui-meme. Dans le cas d'un blindage constitué par une tresse, la mise à la masse est complétée par la prise de la tresse, repliée préalablement sur la bague e , entre cette bague et le corps A, également métallique.The ring e is full, as shown in Figs. 2 and 3 in the case of a cabal armed with a braid; in the case of a target armed with a strip the ring present, as shown in Figs. 4 and 5, radial f, partial or total slots such as the slot shown in f. Finally, the ring e further comprises a bearing surface g on which the seal comes to rest a
The grounding of the shielding (strip or braid) of the target 1 is obtained by pinching the latter between the metal ring e and the screen itself. In the case of a shield consisting of a braid, the earthing is completed by taking the braid, folded beforehand on the ring e, between this ring and the body A, also metallic.
-Les faibles conicité de la portée a2 et de la surface correspondante de la bague e permettent d'exercer une pression importante sur le blindage pour un effort axial obtenu par vissage du chapeau B, rnoddrés même dans le cas d'un cable armé d'un feuiliard, grâce à la présençe de fentes dans la douille e favorisant sa deformation Cette disposition assure une mise à la masse sare et également un renforcement de l'ancrage du cable, ancrage deà réalisé par la douille fendue d. -The low taper of the range a2 and the corresponding surface of the ring e allow to exert a significant pressure on the shielding for an axial force obtained by screwing the cap B, rnoddrés even in the case of a cable armed with a strip, thanks to the presence of slots in the socket e promoting its deformation This arrangement ensures a grounding sare and also a strengthening of the anchoring of the cable, anchoring from made by the split socket d.
En raison de l'appui par la surface s de la bague e sur laquelle vient reposer la garniture d'étanchéité a il se produit, lors du vissage des deux parties du dispositif l'une sur l'autre, une action réciproque de la bague e et de la garniture a qui se traduit par une poussée exercée sur la bague e favorable à l'ancrage supplémentaire réalisé par cette bague. Due to the support by the surface s of the ring e on which the seal comes to rest there is, when the two parts of the device are screwed on one another, a reciprocal action of the ring e and of the lining a which results in a thrust exerted on the ring e favorable to the additional anchoring produced by this ring.
Par ailleurs, l'existence de fentes totales dans la bague e favorise la déformation de la bague meme pour un effort modéré. Furthermore, the existence of total slots in the ring e promotes deformation of the ring even for moderate effort.
Bien entendu l'invention n'est en aucune façon limitée à la forme de réalisation décrite et représentée, mais peut donner lieu à de nombreuses variantes. Il en est ainsi, notamment, de la valeur des conicités conférées aux divers éléments du dispositif ainsi que des différences de conicité que peuvent présenter les surfaces en contact de ces différents éléments. Of course, the invention is in no way limited to the embodiment described and shown, but can give rise to numerous variants. This is the case, in particular, with the value of the conicities imparted to the various elements of the device as well as the differences in conicity which the surfaces in contact with these various elements may exhibit.
