Abstract

The connection comprises a screw fitting mounted at each end of the tube, comprising a threaded conical base (4) and a sleeve (1) which is pierced by a hole of the diameter of the cable conductor (9). The hole in the sleeve is aligned with the point of the cone such that the cable conductor is retained between the outside of the cone and the inside of the apertured section of the sleeve. The connection for an electrical discharge tube comprises a screw fitting mounted at each end on an extension of the tube itself. Each connection includes a threaded conical base (4) and a sleeve (1) which is pierced by a hole of the diameter of the conductor (9) of the supply cable (10). The hole in the sleeve is aligned with the point of the cone such that the cable conductor is retained between the outside of the cone and the inside of the apertured section of the sleeve. A few millimeters of the conductor are stripped of insulation in order to fit into the connection within the sleeve. The sleeve may be formed by a metal cylinder with the wall being externally ridged.

Description

La présente invention a pour objet un dispositif de connexion à vis pour tubes lumineux à décharge. The present invention relates to a screw connection device for gas discharge tubes.

II a pour objet de permettre le raccordement des câbles électriques destinés à assurer l'alimentation haute tension des tubes d'éclairage à décharge et en particulier des tubes de ce type utilisés à l'extérieur. Its purpose is to enable the connection of electrical cables intended to ensure the high voltage supply of discharge lighting tubes and in particular tubes of this type used outside.

Les tubes d'éclairage à décharge, couramment désignés sous le nom de "tube néon" malgré le fait que le gaz qu'ils contiennent varie en fonction de la couleur de la lumière obtenue, sont extrêmement répandus en particulier pour la réalisation d'enseignes lumineuses. Gas discharge tubes, commonly referred to as "neon tubes" despite the fact that the gas they contain varies according to the color of the light obtained, are extremely common, especially for the production of signs. bright.

Lorsqu'un gaz raréfié est soumis à une différence de potentiel, il s'ionise spontanément et devient ainsi conducteur. Le passage du courant électrique excite les électrons des couches périphériques des atomes du gaz raréfié qui, lorsqu'ils retombent à leur position d'équilibre, émettent de la lumière. A l'inverse de la lumière engendrée par le rayonnement des corps chauds, qui comporte un spectre de fréquence continu, cette lumière froide est composée de quelques raies d'émissions monochromatiques, caractéristiques du gaz utilisé. C'est ainsi que certains tubes à décharge émettent sur une seule raie visible, par exemple rouge dans le cas du néon, ou jaune dans le cas de la vapeur de sodium. When a rarefied gas is subjected to a potential difference, it spontaneously ionizes and thus becomes conductive. The passage of the electric current excites the electrons of the peripheral layers of the atoms of the rarefied gas which, when they fall back to their equilibrium position, emit light. In contrast to the light generated by the radiation of hot bodies, which has a continuous frequency spectrum, this cold light is composed of some lines of monochromatic emissions, characteristic of the gas used. Thus some discharge tubes emit on a single visible line, for example red in the case of neon, or yellow in the case of sodium vapor.

Ces tubes, pour fonctionner, doivent être alimentés sous haute tension, cette tension pouvant dépasser 5000 volts pour les tubes de grande longueur. C'est la raison pour laquelle, outre le fait que ce matériel est souvent installé dans des lieux publics, les connexions électriques doivent être particulière ment sûres et fiables. These tubes, to function, must be supplied with high voltage, this voltage being able to exceed 5000 volts for the tubes of great length. That is why, besides the fact that this material is often installed in public places, the electrical connections must be particularly safe and reliable.

Jusqu'à un passé récent, le raccordement des câbles s'effectuait au moyen de bornes de types variés, par soudure ou par épissure. Until recently, cable connections were made by means of terminals of various types, by welding or splicing.

La norme européenne EN 50107, obligatoire depuis le 1 er janvier 1999 précise dans ses textes qu'à partir du 1 er mars 2000, l'utilisation des électrodes à connexion à vis est obligatoire, aussi bien pour des installations situées à l'intérieur que pour celles situées à l'extérieur. Par ailleurs, toutes les connexions aux tubes à décharge doivent être protégées au moyen de manchons isolants. The European standard EN 50107, mandatory since January 1, 1999 specifies in its texts that from March 1, 2000, the use of electrodes with screw connection is mandatory, both for indoor installations and for those outside. In addition, all connections to the discharge tubes must be protected by means of insulating sleeves.

Le dispositif selon la présente invention a pour but de proposer un système de connexion pour tubes à décharge conforme aux dernières normes en vigueur, tout en étant particulièrement facile à mettre en oeuvre. The device according to the present invention aims to provide a connection system for discharge tubes according to the latest standards in force, while being particularly easy to implement.

II est constitué d'un connecteur à vis monté dans le prolongement du tube à décharge, à chacune de ses extrémités, et comportant une embase conique filetée et un manchon taraudé pourvu d"un perçage adapté à la section de l'âme du câble électrique à raccorder et disposé de manière à se trouver en face de la pointe du cône de l'embase. It consists of a screw connector mounted in the extension of the discharge tube, at each of its ends, and comprising a threaded conical base and a threaded sleeve provided with a bore adapted to the section of the core of the electric cable. to be connected and arranged so as to face the tip of the cone of the base.

Sur les dessins annexés, donnés à titre d'exemples non limitatifs de formes de réalisation de l'objet de l'invention: la figure 1 représente, vue de côté, l'extrémité d'un tube à décharge équipé du connecteur revendiqué, la figure 2 montre le connecteur avec manchon entièrement dévissé, la figure 3 est une coupe axiale agrandie du manchon, La figure 4 représente dans les mêmes conditions un connecteur avec câble électrique raccordé et la figure 5 montre une variante du connecteur avec capot isolant. Le dispositif, figures 1 à 5, est formé d'un manchon creux 1 taraudé se vissant sur un embout 2 métallique monté à l'extrémité du tube d'éclairage 3. In the accompanying drawings, given by way of non-limiting examples of embodiments of the subject of the invention: FIG. 1 represents, viewed from the side, the end of a discharge tube equipped with the claimed connector; Figure 2 shows the connector with fully unscrewed sleeve, Figure 3 is an enlarged axial section of the sleeve, Figure 4 shows in the same conditions a connector with electrical cable connected and Figure 5 shows a variant of the connector with insulating cover. The device, FIGS. 1 to 5, is formed of a threaded hollow sleeve 1 screwed onto a metal end-piece 2 mounted at the end of the lighting tube 3.

L'embout 2 est constitué de deux éléments solidaires coaxiaux au tube 3 : une embase filetée 4 connectée électriquement à l'électrode 5 interne du tube, et une pointe conique 6. The tip 2 consists of two integral elements coaxial with the tube 3: a threaded base 4 electrically connected to the inner electrode 5 of the tube, and a conical tip 6.

Le manchon creux 1 consiste en un cylindre métallique à paroi latérale 7 externe striée, pourvu d'un fond perpendiculaire à l'axe du connecteur comportant un perçage 8 à bords évasés dont le diamètre est déterminé pour permettre le passage du conducteur 9 du câble électrique 10. Lorsque le manchon 1 est vissé sur l'embout 2, ce perçage se trouve face à la pointe conique 6. The hollow sleeve 1 consists of a metal cylinder with striated outer side wall 7, provided with a bottom perpendicular to the axis of the connector having a bore 8 with flared edges whose diameter is determined to allow the passage of the conductor 9 of the electric cable. 10. When the sleeve 1 is screwed on the tip 2, this hole is opposite the conical tip 6.

Afin d'éviter de perdre le manchon 1 durant les opérations de connexion, son taraudage et le filetage de l'embout 2 pourront avantageusement être agencés d'une manière connue de façon à ce que le manchon 1 puisse être aisément vissé ou dévissé à la main, mais qu'il ne puisse pas être séparé de l'embout sans outillage. In order to avoid losing the sleeve 1 during the connection operations, its tapping and the threading of the tip 2 may advantageously be arranged in a known manner so that the sleeve 1 can be easily screwed or unscrewed to the hand, but that it can not be separated from the bit without tools.

La connexion du câble 10 s'effectue, après l'avoir dénudé sur quelques millimètres, en desserrant préalablement le manchon 1, puis en enfilant le conducteur 9 du câble dans le perçage 8 de manière à ce que les brins du conducteur soient écartés par la pointe conique 6 de l'embout 2 et viennent se loger entre celle-ci et la paroi interne du manchon 1. Ce dernier est alors vissé fermement, éventuellement au moyen d'une pince, de façon à ce que les brins du conducteur 9 soient serrés entre le fond du manchon 1 et la pointe conique de l'embout 2. The connection of the cable 10 is made, after having stripped a few millimeters, by previously loosening the sleeve 1 and then threading the conductor 9 of the cable in the bore 8 so that the strands of the conductor are separated by the cone tip 6 of the nozzle 2 and are housed between it and the inner wall of the sleeve 1. The latter is then screwed firmly, possibly by means of a clamp, so that the strands of the driver 9 are tightened between the bottom of the sleeve 1 and the conical tip of the tip 2.

L'isolation de la connexion peut s'effectuer au moyen d'une gaine thermo rétractable ou non de type connu. Cependant, selon une variante d'exécution, le connecteur pourra être recouvert d'un capot isolant 11 solidaire de l'embout 2 et comportant une partie amovible 12 permettant d'avoir accès au manchon 1. The insulation of the connection can be effected by means of a heat shrinkable sheath or not of known type. However, according to an alternative embodiment, the connector may be covered with an insulating cover 11 integral with the endpiece 2 and having a removable portion 12 for access to the sleeve 1.

Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.The positioning of the various constituent elements gives the object of the invention a maximum of useful effects that had not been obtained so far by similar devices.
