Description

La présente invention concerne d'une manière générale les boítiers de raccordement pour câbles coaxiaux destinés à la distribution de signaux haute fréquence, et, plus particulièrement, de signaux de télévision.The present invention relates generally connection boxes for coaxial cables intended for the distribution of high frequency signals, and, more especially television signals.

Un boítier connu est décrit, par example, dans le document FR-A-2 191 296.A known case is described, for example, in document FR-A-2 191 296.

Eu égard à l'obligation qu'il y a de plus en plus fréquemment d'assurer en un même point de raccordement la distribution de signaux de provenances très diverses, tels que par exemple des signaux en provenance d'antennes hertziennes, de satellites, ou de câbles, il est souhaitable de pouvoir élargir au mieux, jusqu'au point terminal d'utilisation, le spectre des fréquences nécessaires, et d'assurer avec un rendement optimal la transmission des signaux du câble coaxial d'arrivée au câble coaxial de départ.Having regard to the obligation that there is more and more frequently to ensure at the same connection point distribution of signals from a wide variety of sources, such as for example signals from radio antennas, satellites, or cables, it is desirable to be able to widen as far as possible, up to the terminal point of use spectrum of necessary frequencies, and ensure with a optimal performance the transmission of coaxial cable signals of the coaxial cable.

La présente invention a pour objet un boítier de raccordement répondant à ce but.The present invention relates to a housing of connection meeting this goal.

Ce boítier de raccordement est caractérisé par les caractéristiques de la revendication 1.This connection box is characterized by the characteristics of claim 1.

Ainsi l'enveloppe externe du boítier de raccordement suivant l'invention assure par elle-même le blindage nécessaire ; elle assure également par elle-même la mise à la masse de l'ensemble, et, notamment, celle du blindage du câble coaxial d'arrivée.Thus the outer casing of the connection box according to the invention ensures by itself the shielding necessary ; it also ensures by itself the mass of the assembly, and in particular that of the cable shield coaxial arrival.

Mais, conjointement, la pièce en matière isolante prévue suivant l'invention en aval de la borne de connexion reconstitue, avantageusement, autour de la partie dénudée de l'âme du câble coaxial d'arrivée, une gaine isolante, qui, sensiblement en liaison avec la partie diélectrique de ce câble coaxial d'arrivée, est favorable à une bonne continuité d'impédance pour l'ensemble, et, donc, à une bonne adaptation d'impédance du câble coaxial de départ par rapport au câble coaxial d'arrivée.But, jointly, the piece of insulating material provided according to the invention downstream of the connection terminal advantageously reconstructs around the stripped part of the core of the incoming coaxial cable, an insulating sheath, which, substantially in connection with the dielectric part of this cable coaxial arrival, is favorable for good continuity of impedance for the whole, and, therefore, to a good adaptation impedance of the starting coaxial cable with respect to the cable coaxial arrival.

Préférentiellement, la tête de la vis de serrage de la borne de connexion, qui est en pratique métallique, intervient à frottement dans une cheminée appartenant à l'enveloppe externe.Preferably, the head of the clamping screw of the connection terminal, which is in practice metallic, intervenes friction in a chimney belonging to the envelope external.

Ainsi, l'étanchéité du blindage se trouve assurée quelle que soit la longueur de vissage de cette vis de serrage, au bénéfice d'un maintien des qualités de ce blindage.Thus, the sealing of the shielding is ensured whatever the screwing length of this clamping screw, for the benefit of maintaining the qualities of this armor.

En outre, il est ainsi avantageusement possible de connecter et de déconnecter le câble coaxial d'arrivée sans nuire aux qualités de ce blindage.Furthermore, it is thus advantageously possible to connect and disconnect the incoming coaxial cable without harm the qualities of this shield.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels :

  • la figure 1 est une vue en coupe longitudinale d'un boítier de raccordement suivant l'invention ;
  • la figure 2 en est une vue partielle en coupe transversale, suivant la ligne II-II de la figure 1, avant le serrage de l'âme du câble coaxial d'arrivée ;
  • la figure 3 en est une autre vue partielle en coupe transversale, suivant la ligne III-III de la figure 1, après ce serrage.
    • The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended schematic drawings in which:
  • Figure 1 is a longitudinal sectional view of a connection box according to the invention;
  • Figure 2 is a partial view in cross section along the line II-II of Figure 1, before tightening the core of the incoming coaxial cable;
  • Figure 3 is another partial view in cross section along the line III-III of Figure 1, after this tightening.

    • Tel qu'illustré sur la figure 1, le boítier de raccordement 10 suivant l'invention est destiné à permettre le raccordement, à un câble coaxial d'arrivée 11, d'un câble coaxial de départ 12, pour la distribution de signaux haute fréquence, et, plus précisément, de signaux de télévision.As illustrated in Figure 1, the housing of connection 10 according to the invention is intended to allow the connection, to an incoming coaxial cable 11, of a cable starting coaxial 12, for high signal distribution frequency, and more specifically, of television signals.

    De manière connue en soi, le câble coaxial d'arrivée 11 comporte, successivement, de l'intérieur vers l'extérieur, une âme centrale 13, qui est métallique, une gaine isolante 14 interne, qui forme un diélectrique, une tresse métallique 15 intermédiaire, qui forme un blindage, et une gaine isolante 16 externe, qui assure le protection de l'ensemble.In a manner known per se, the incoming coaxial cable 11 comprises, successively, from the inside to the outside, a central core 13, which is metallic, an insulating sheath 14 internal, which forms a dielectric, a metallic braid 15 intermediate, which forms a shield, and an insulating sheath 16 external, which ensures the protection of the whole.

    Le câble coaxial de départ 12 a une constitution identique.The starting coaxial cable 12 has a constitution identical.

    Le boítier de raccordement 10 suivant l'invention comporte, globalement, une enveloppe externe 18, qui forme un blindage, et qui présente, d'une part, une entrée 20, pour l'engagement du câble coaxial d'arrivée 11, et, d'autre part, une sortie 21, pour l'enfichage du câble coaxial de départ 12.The connection box 10 according to the invention comprises, overall, an outer envelope 18, which forms a shielding, and which has, on the one hand, an input 20, for the engagement of the incoming coaxial cable 11, and, on the other hand, an output 21, for plugging in the starting coaxial cable 12.

    L'entrée 20 permet le raccordement de l'enveloppe externe 18 au blindage du câble coaxial d'arrivée 11, c'est-à-dire à sa tresse métallique 15, celle-ci étant dûment retournée en doigt de gant à cet effet sur la gaine isolante 16 externe après avoir été dénudée.Input 20 allows connection of the enclosure external 18 to the shield of the incoming coaxial cable 11, that is to say to its metal braid 15, this being duly returned as a thermowell for this purpose on the outer insulating sheath 16 after being naked.

    Dans la forme de réalisation représentée, l'axe de cette entrée 20 s'étend en oblique par rapport à celui de la sortie 21.In the embodiment shown, the axis of this entry 20 extends obliquely to that of the exit 21.

    Conjointement, la sortie 21 comporte, de manière classique, une broche 22, métallique, dans l'axe d'une douille 23, également métallique, pour coopération avec un embout 24 dont est muni, de manière également classique, à son extrémité, le câble coaxial d'arrivée 11, avec, entre la broche 22 et la douille 23, une masse en matière isolante 25.At the same time, exit 21 includes, so classic, a pin 22, metallic, in the axis of a socket 23, also metallic, for cooperation with a nozzle 24 which is provided, also conventionally, at its end, the incoming coaxial cable 11, with, between pin 22 and the socket 23, a mass of insulating material 25.

    Suivant des dispositions décrites plus en détail ultérieurement, la douille 23 de la sortie 21 est dûment raccordée à l'enveloppe externe 18.According to arrangements described in more detail subsequently, the socket 23 of the outlet 21 is duly connected to the outer casing 18.

    Dans l'enveloppe externe 18 intervient, tout d'abord, de manière usuelle, une borne de connexion 26, pour le raccordement de l'âme centrale 13 du câble coaxial d'arrivée 11. In the outer envelope 18, first of all, in the usual way, a connection terminal 26, for the connection of the central core 13 of the incoming coaxial cable 11.

    Suivant l'invention, cette borne de connexion 26 comporte un siège 27, métallique, qui, disposé sensiblement dans l'axe de l'entrée 20, est destiné à recevoir cette âme centrale 13, et qui est raccordé à la broche 22 de la sortie 21, et une vis de serrage 28, qui, suivant des dispositions décrites plus en détail ultérieurement, est accessible de l'extérieur.According to the invention, this connection terminal 26 comprises a seat 27, metallic, which, disposed substantially in the axis of the entrance 20, is intended to receive this soul central 13, and which is connected to pin 22 of the output 21, and a clamping screw 28, which, according to arrangements described in more detail later, is accessible from outside.

    Dans la forme de réalisation représentée, le siège 27 est en V.In the embodiment shown, the seat 27 is in V.

    Plus précisément, il est formé par la tranche d'un flasque 29 présentant une creusure en V, dont la concavité est tournée vers la vis de serrage 28, et dont l'arête est en pratique inclinée par rapport à l'axe de celle-ci, en étant sensiblement dans l'alignement de l'axe de l'entrée 20.More specifically, it is formed by the edge of a flange 29 having a V-shaped recess, the concavity of which is facing the clamping screw 28, and the edge of which is in practice inclined with respect to the axis thereof, being substantially in alignment with the axis of entry 20.

    Dans la forme de réalisation représentée, le siège 27 est en outre d'un seul tenant avec la broche 22 de la sortie 21.In the embodiment shown, the seat 27 is also integral with pin 22 of the outlet 21.

    Plus précisément, le flasque 29 qui le forme constitue l'une des ailes d'une pièce en équerre 30 dont l'autre aile 31 porte à son dos la broche 22.More precisely, the flange 29 which forms it constitutes one of the wings of a square piece 30 of which the other wing 31 has pin 22 on its back.

    Dans l'enveloppe externe 18 intervient, en outre, suivant l'invention, en aval du siège 27 par rapport à l'entrée 20, une pièce en matière isolante 32, qui, dans le prolongement de ce siège 27, forme un logement 34 pour l'extrémité de l'âme centrale 13 du câble coaxial d'arrivée 11, cette pièce en matière isolante 32 comportant, pour la définition de ce logement 34, une embase 35, fixe, et un couvercle 36, mobile, sur lequel porte, en pratique, la vis de serrage 28, par son fût 37.In the outer envelope 18, moreover, according to the invention, downstream of the seat 27 relative to the inlet 20, a piece of insulating material 32, which, in the extension of this seat 27, forms a housing 34 for the end of the core central 13 of the incoming coaxial cable 11, this part in insulating material 32 comprising, for the definition of this housing 34, a base 35, fixed, and a cover 36, movable, on which bears, in practice, the clamping screw 28, by its was 37.

    Dans la forme de réalisation représentée, la pièce en matière isolante 32 est accolée au siège 27, et, plus précisément, au flasque 29 formant celui-ci.In the embodiment shown, the part in insulating material 32 is attached to the seat 27, and, more specifically, the flange 29 forming it.

    Par son embase 35, elle est d'un seul tenant avec la masse en matière isolante 25 de la sortie 21, et, dans la forme de réalisation représentée, la pièce en équerre 30 est encastrée en surface dans l'ensemble par son aile 31. By its base 35, it is in one piece with the mass of insulating material 25 from outlet 21, and, in the form embodiment shown, the square part 30 is recessed on the surface as a whole by its wing 31.

    Dans la forme de réalisation représentée, le couvercle 36 de la pièce en matière isolante 32 est articulé transversalement à son embase 35 du côté de celle-ci opposé au siège 27, et il est en pratique d'un seul tenant avec cette embase 35.In the embodiment shown, the cover 36 of the piece of insulating material 32 is articulated transversely to its base 35 on the side thereof opposite the seat 27, and it is in practice in one piece with this base 35.

    Plus précisément, dans cette forme de réalisation, l'embase 35 forme, latéralement, deux flasques 38, qui encadrent le flasque 29 formant le siège 27, et entre lesquels se débat, pour son guidage, le couvercle 36.More specifically, in this embodiment, the base 35 forms, laterally, two flanges 38, which frame the flange 29 forming the seat 27, and between which struggles, for its guidance, the cover 36.

    Ainsi qu'on le notera, le logement 34 que forme la pièce en matière isolante 32 n'a ainsi qu'un seul accès, celui qui, tourné vers l'entrée 20, permet d'y introduire l'âme centrale 13 du câble coaxial d'arrivée 11.As will be noted, the housing 34 formed by the piece of insulating material 32 thus has only one access, that which, facing entrance 20, allows the introduction of the soul control unit 13 of the incoming coaxial cable 11.

    Dans la forme de réalisation représentée, la vis de serrage 28 est métallique, et, pour la continuité du blindage formé par l'enveloppe externe 18, sa tête 40 intervient à frottement dans une cheminée 41 appartenant à cette enveloppe externe 18.In the embodiment shown, the screw clamp 28 is metallic, and for the continuity of the shielding formed by the outer casing 18, its head 40 acts at friction in a chimney 41 belonging to this envelope external 18.

    Conjointement, le fût 37 de cette vis de serrage 28 est en prise à vissage avec une douille 43, qui, appartenant elle aussi à l'enveloppe externe 18, fait saillie sur la surface interne de celle-ci, dans l'axe de la cheminée 41, et à l'aplomb du couvercle 36 de la pièce en matière isolante 32.Together, the barrel 37 of this clamping screw 28 is in screw connection with a socket 43, which, belonging also to the outer casing 18, protrudes from the internal surface thereof, in the axis of the chimney 41, and directly above the cover 36 of the piece of insulating material 32.

    Pour former un blindage, l'enveloppe externe 18 est, par exemple, en métal.To form a shield, the outer envelope 18 is, for example, metal.

    Mais, en variante, elle peut également être en matière synthétique dûment métallisée.But, as a variant, it can also be in terms of duly metallized synthetic.

    Dans la forme de réalisation représentée, cette enveloppe externe 18 est en deux parties 18A, 18B, à savoir, une partie 18A, qui forme par elle-même la douille 43 prévue pour la vis de serrage 28 de la borne de connexion 26, et une partie 18B, qui forme par elle-même la douille 23 de la sortie 21, et, de préférence, ces deux parties 18A, 18B sont dûment solidarisées l'une à l'autre, par exemple par des moyens de vissage ou des moyens d'encliquetage non visibles sur les figures. In the embodiment shown, this outer envelope 18 is in two parts 18A, 18B, namely, a part 18A, which by itself forms the socket 43 provided for the clamping screw 28 of the connection terminal 26, and a part 18B, which in itself forms the socket 23 of the outlet 21, and preferably these two parts 18A, 18B are duly joined together, for example by means of screwing or latching means not visible on the figures.

    Si désiré, les parties 18A, 18B de l'enveloppe externe 18 forment, en outre, conjointement, au niveau de l'entrée 20, un serre-câble 44, pour le serrage du câble coaxial d'arrivée 11.If desired, parts 18A, 18B of the outer shell 18 also form, jointly, at the entrance 20, a cable clamp 44, for tightening the incoming coaxial cable 11.

    En service, le couvercle 36 de la pièce en matière isolante 32 vient, sous l'action de la vis de serrage 28, enfermer totalement dans le logement 34 prévu à cet effet l'extrémité de l'âme centrale 13 du câble coaxial d'arrivée 11.In service, the cover 36 of the workpiece insulator 32 comes under the action of the clamping screw 28, completely enclose in the housing 34 provided for this purpose the end of the central core 13 of the incoming coaxial cable 11.

    Conjointement, sous cette même action, cette âme centrale 13 se trouve dûment connectée au siège 27, et, donc, dûment reliée par celui-ci à la broche 22 de la sortie 21.Jointly, under this same action, this soul control unit 13 is duly connected to seat 27, and therefore duly connected by it to pin 22 of output 21.

    Bien entendu, la présente invention ne se limite pas à la forme de réalisation décrite et représentée, mais englobe toute variante d'exécution.Of course, the present invention is not limited to the embodiment described and shown, but encompasses any variant of execution.
