Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention a pour objet un connecteur de câble électrique pour tubes lumineux à décharge.  The present invention relates to an electrical cable connector for discharge light tubes.

Il 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 allow the connection of electrical cables intended to supply high voltage to discharge lighting tubes and in particular tubes of this type used outside.

Les tubes d'éclairage à décharge sont extrêmement répandus en particulier pour la réalisation d'enseignes lumineuses. 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 particulièrement sûres et fiables.  Discharge lighting tubes are extremely widespread, in particular for the production of illuminated signs. To operate, these tubes must be supplied with high voltage, this voltage being able to exceed 5000 volts for very long tubes. This is why, in addition to the fact that this equipment is often installed in public places, the electrical connections must be particularly safe and reliable.

La norme européenne EN 50107, obligatoire depuis le 1er 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

Figure img00010001

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 screw connection electrodes is mandatory, both for indoor installations and for those located outside. In addition, all connections to the tubes to
Figure img00010001

discharge must be protected by insulating sleeves.

Il existe de nombreux systèmes de connexion pour tubes à décharge. A titre d'exemples, on peut citer le brevet ? EP 0 911 915 qui décrit un dispositif constitué d'un écrou de serrage se vissant sur une tige filetée solidaire du tube lumineux et qui comporte un canal recevant le câble à raccorder, ce canal présentant un tronçon axial et un tronçon radial qui se raccordent l'un à l'autre. There are many connection systems for discharge tubes. As examples, one can quote the patent? EP 0 911 915 which describes a device consisting of a tightening nut screwing onto a threaded rod integral with the light tube and which comprises a channel receiving the cable to be connected, this channel having an axial section and a radial section which are connected to each other.

Le brevet No FR 2 777 122 fait état d'un connecteur du même type constitué d'une seule pièce conductrice coiffant l'extrémité du tube à décharge et comportant une borne à vis à perçage axial.  Patent No FR 2,777,122 describes a connector of the same type consisting of a single conductive piece covering the end of the discharge tube and comprising a screw terminal with axial drilling.

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

L'embase 1 est constituée d'un élément fileté en matière synthétique isolante scellé à l'extrémité du tube à décharge 2 et comportant un filetage 5 permettant de monter l'embout 3 métallique.  The base 1 consists of a threaded insulating synthetic element sealed at the end of the discharge tube 2 and comprising a thread 5 allowing the metal end piece 3 to be mounted.

L'embout 3 comporte une extrémité conique 6 et une extrémité opposée taraudée 7 permettant sa fixation sur l'embase 1. Il comporte un canal central 8 axial borgne recevant la tige de connexion 9 métallique raccordé à l'électrode 10 du tube à décharge 2, le contact électrique entre cette tige et l'embout 3 étant assuré grâce à un ressort 11 s'enfilant sur la tige de connexion et se logeant dans le canal 8.  The end piece 3 has a conical end 6 and an opposite tapped end 7 allowing it to be fixed on the base 1. It has a central blind axial channel 8 receiving the metal connection rod 9 connected to the electrode 10 of the discharge tube 2 , the electrical contact between this rod and the end piece 3 being ensured by means of a spring 11 threading on the connection rod and being housed in the channel 8.

Le manchon creux 4 consiste en un cylindre métallique à paroi latérale 12 externe striée, pourvu d'un fond perpendiculaire à l'axe du connecteur comportant un perçage 13 à bords évasés disposé face à la partie conique 6 de l'embout 3, et dont le diamètre est déterminé pour permettre le passage du conducteur 14 du câble électrique 15.  The hollow sleeve 4 consists of a metal cylinder with a striated external side wall 12, provided with a bottom perpendicular to the axis of the connector comprising a bore 13 with flared edges disposed opposite the conical part 6 of the end piece 3, and of which the diameter is determined to allow the passage of the conductor 14 of the electric cable 15.
