Description

La présente invention concerne un connecteur pour tube cathodique, principalement prévu pour les récepteurs de télévision en couleurs.The present invention relates to a connector for cathode ray tube, mainly intended for color television receivers.

Ce type de connecteur est destiné à assurer respectivement les liaisons électriques entre les différents circuits reliés à la carte imprimée et les éléments inclus dans le tube, cathodes pour fonctions rouge, bleue, verte, grilles 1 et 2, filaments 1 et 2.This type of connector is intended to ensure respectively the electrical connections between the different circuits connected to the printed circuit board and the elements included in the tube, cathodes for red, blue, green functions, grids 1 and 2, filaments 1 and 2.

On sait que les éléments précités inclus dans le tube doivent être orotégés contre les surtensions. A cet effet, on adjoint a ces connecteurs des éclateurs indépendants ou intégrés, dont la décharge en cas de surtension assure la protection requise.It is known that the aforementioned elements included in the tube must be orotected against overvoltages. To this end, independent or integrated spark gaps are added to these connectors, the discharge of which in the event of an overvoltage provides the required protection.

Il existe actuellement plusieurs types de connecteurs pour tubes cathodiques. On citera parmi ceux-ci deux types représentant deux techniques différentes.There are currently several types of connectors for cathode ray tubes. Among these are two types representing two different techniques.

Suivant le premier type, le connecteur est constitué par une pièce isolante moulée,en forme générale de bague, à l'inté- de laquelle sont disposées, isolées les unes des autres par des cannelures longitudinales, ou dans des alvéoles ,les pièces conductrices prévues pour être au contact des broches du tube. Dans ce cas,la protection recherchée est obtenue au moyen d'éclateurs indépendants de la bague ou prévus directement dans ou sur le circuit imprimé concerné.According to the first type, the connector consists of a molded insulating part, generally in the form of a ring, inside which are arranged, isolated from each other by longitudinal grooves, or in cells, the conductive parts provided to be in contact with the pins of the tube. In this case, the protection sought is obtained by means of spark gaps independent of the ring or provided directly in or on the printed circuit concerned.

Suivant un autre type, le connecteur est constitué par une pièce formant boîtier, dans lequel sont inclus à la fois les pièces de contact et leurs éclateurs correspondants, convenablement isolés et disposés de manière à assurer les liaisons requises et la protection recherchée.According to another type, the connector is constituted by a part forming a housing, in which are included both the contact parts and their corresponding spark gaps, suitably insulated and arranged so as to provide the required connections and the desired protection.

La fabrication d'un tel connecteur est complexe;le montage des éclateurs à l'intérieur du boîtier est délicat, de plus le coût en est élevé et l'encombrement relativement important.The manufacture of such a connector is complex; the mounting of the spark gaps inside the housing is delicate, moreover the cost is high and the dimensions relatively large.

La présente invention a pour objet un connecteur à éclateurs incorporés constituant un perfectionnement apporté aux connecteurs du premier type précité,et dont la fabrication est simplifiée, le coût diminué et l'encombrement réduit par rapport aux connecteurs du second type indiqué ci-dessus.The subject of the present invention is a connector with incorporated spark gaps constituting an improvement made to the connectors of the first type mentioned above, and the manufacture of which is simplified, the cost reduced and the bulk reduced compared to the connectors of the second type indicated above.

A cet effet, sur la paroi extérieure de la bague constituant le connecteur est prévue une ceinture incluant des logements destinés à recevoir les différents éclateurs et leur masse commune.For this purpose, a belt is provided on the outer wall of the ring constituting the connector, including housings intended to receive the different spark gaps and their common mass.

Ces éclateurs peuvent être du type obtenu par surmoulage d'une bande continue d'un matériau conducteur approprié, convenablement ajourée dont ils sont ensuite détachés mécaniquement et simultanément. L'écartement nécessaire,fonction de la tension, est réalisé pour chaque éclateur par découpe, avec simultanément élimination des parties inutiles de la bande.These spark gaps can be of the type obtained by overmolding a continuous strip of a suitable conductive material, suitably perforated from which they are then mechanically and simultaneously detached. The necessary spacing, depending on the voltage, is made for each spark gap by cutting, simultaneously eliminating unnecessary parts of the strip.

Suivant une variante avantageuse, la bague peut en outre être pourvue à sa périphérie d'un bossage formant logement prévu pour recevoir la broche de la grille de focalisation ainsi que le moyen contact destiné à relier cette dernière au circuit d'alimentation correspondant, cette disposition étant possible lorsque la broche de la grille G3 est suffisamment distante des autres broches les plus proches.According to an advantageous variant, the ring can also be provided at its periphery with a boss forming a housing provided for receiving the pin of the focusing grid as well as the contact means intended to connect the latter. to the corresponding supply circuit, this arrangement being possible when the pin of the gate G3 is sufficiently distant from the other nearest pins.

On décrira ci-après une forme de réalisation d'un connecteur suivant l'invention en se référant au dessin annexé donné à titre indicatif, dans lequel :

  • La figure 1 représente schématiquement en perspective un connecteur selon l'invention,
  • La figure 2 représente vu de dessous l'ensemble du connecteur avec pièces de contact et éclateurs associés ,
  • La figure 3 représente de profil, en vue agrandie, la disposition d'une pièce de contact et de son éclateur associé.
  • Les figures 4 et 5 représentent respectivement en élévation coupe et en plan une variante suivant laquelle une disposition particulière est prévue pour le logement et la connexion de la broche reliée à la grille de focalisation G3.
An embodiment of a connector according to the invention will be described below with reference to the appended drawing given for information, in which:
  • FIG. 1 diagrammatically shows in perspective a connector according to the invention,
  • FIG. 2 represents seen from below the whole of the connector with associated contact parts and spark gaps,
  • Figure 3 shows in profile, in enlarged view, the arrangement of a contact piece and its associated spark gap.
  • Figures 4 and 5 show respectively in sectional elevation and in plan a variant according to which a particular arrangement is provided for the housing and the connection of the pin connected to the focusing grid G3.

Sur la figure 1, la référence 1 désigne le corps du connecteur en matière isolante moulée, en forme générale de bague oblongue,à l'intérieur de laquelle sont disposées les pièces conductrices au contact des broches du tube cathodique. Ces pièces connues en elles-mêmes sont représentées figure 2.In FIG. 1, the reference 1 designates the body of the connector made of molded insulating material, generally in the form of an oblong ring, inside which the conductive parts are arranged in contact with the pins of the cathode-ray tube. These parts, known in themselves, are shown in FIG. 2.

La référence 2 désigne une partie venue de moulage ceinturant la baguent qui inclut les logements prévus pour les différents éclateurs. Dans cet exemple, ceux-ci sont constitués de la manière suivante : la bande métallique 3 solidaire des différentes parties 4 relie à la masse les éclateurs proprement dits constitués respectivement par les extrémités libres en regard des parties 4 et 5 (visibles sur la figure 3) maintenues à la très faible distance requise par la pièce isolante surmoulée 6. L'extrémité opposée des parties 5 est prévue pour pénétrer dans la carte imprimée de liaison aux circuits, par un trou prévu à cet effet, et conjointement avec une pièce de contact assurant la liaison électrique avec la broche correspondante du tube cathodique.The reference 2 designates a part molded around the ring which includes the housing provided for the different spark gaps. In this example, these are constituted in the following manner: the metal strip 3 integral with the different parts 4 connects to the ground the spark gaps proper constituted respectively by the free ends opposite the parts 4 and 5 (visible in FIG. 3 ) kept at the very short distance required by the overmolded insulating part 6. The opposite end of the parts 5 is provided to penetrate the printed circuit connection card, through a hole provided for this purpose, and jointly with a contact part ensuring the electrical connection with the corresponding pin of the cathode ray tube.

La référence 7 désigne des nervures dont la pièce 2 est pourvue pour former les différents logements des éclateurs.The reference 7 designates ribs which the part 2 is provided to form the different housings of the spark gaps.

La représentation donnée sur la figure est bien entendu schématique, l'espace libre entre les pièces 6 et les nervures 7 étant évidemment, dans la pratique, réduit de manière à permettre la mise en place requise mais sans jeu.The representation given in the figure is of course schematic, the free space between the parts 6 and the ribs 7 being obviously, in practice, reduced so as to allow the required positioning but without play.

La référence 8 désigne une partie excentrée de la bague prévue pour loger une partie correspondante excentrée du culot du tube, cette dernière constituant elle-même logement pour le connecteur de focus .The reference 8 designates an eccentric part of the ring provided for housing a corresponding eccentric part of the base of the tube, the latter itself constituting housing for the focus connector.

La référence 9 désigne un moyen détrompeur supplémentaire de la bague par rapport au culot du tube, ayant en outre pour fonction d'assurer l'isolement parfait des pièces de contact qui lui sont contigües.The reference 9 designates an additional polarizing means of the ring relative to the base of the tube, further having the function of ensuring perfect isolation of the contact parts which are contiguous to it.

La référence 10 désigne des moyens d'accrochage du connecteur sur la carte imprimée de liaison aux circuits. Ces moyens d'accrochage, en forme de double harpon, constituent un moyen détrompeur destiné à éviter toute erreur lors de la mise en place sur la carte imprimée. En outre, ils assurent la bonne tenue du connecteur sur la carte imprimée lors de l'opération de soudure au bain ,ou ultérieurement, en cas de démontage de la carte imprimée par rapport au tube.The reference 10 designates means for attaching the connector to the printed circuit connection card. These attachment means, in the form of a double harpoon, constitute a polarizing means intended to avoid any error during the positioning on the printed card. In addition, they ensure the good behavior of the connector on the printed card during the soldering operation in the bath, or later, in case of dismantling of the printed card with respect to the tube.

Dans l'exemple représenté les moyens 10 sont disposés sur la partie excentrée 8 de la bague 1, mais ils pourraient bien entendu être disposés en d'autres points.In the example shown the means 10 are arranged on the eccentric part 8 of the ring 1, but they could of course be arranged at other points.

La figure 3 représentfe une vue agrandie, de profil, de la disposition d'un contact et de l'éclateur associé faisant partie de l'ensemble des éclateurs mis en place simultanément dans leurs logements respectifs où ils sont maintenus par encliquetage.FIG. 3 represents an enlarged view, in profile, of the arrangement of a contact and of the associated spark gap forming part of the set of spark gaps set up simultaneously in their respective housings where they are held by snap-fastening.

rar glissement des extrémités de chacune des parties 5 des éclateurs respectivement le long des extrémités des pièces de contact correspondantes (comme représenté sur la figure 3), on obtient une superposition de ces pièces deux à deux suffisante pour que lors de la mise en place dans les trous prévus 3 cet effet dans la carte imprimée, la solidarisation par soudure des dites nièces avec la carte ouisse être effectuée en une seule onération.rar sliding of the ends of each of the parts 5 of the spark gaps respectively along the ends of the corresponding contact parts (as shown in FIG. 3), one obtains a superposition of these parts two by two sufficient so that during the positioning in the holes provided for this purpose in the printed card, the joining by welding of said nieces with the card can be carried out in a single oneration.

Les formes adoptées pour les parties surmoulées 6 entourant les éclateurs sont prévues de telle sorte qu'après mise en place de l'éclateur on obtienne une étanchéité suffisante pour protéger de la pénétration de la poussière et, dans une certaine mesure, du ruissellement, sans toutefois empécher l'évacuation de l'ozone dégagé par le fonctionnement de l'éclateur, pour laquelle sont prévues de petites ouies latérales 11.The shapes adopted for the overmolded parts 6 surrounding the spark gaps are provided so that after fitting the spark gap, a sufficient seal is obtained to protect from the penetration of dust and, to a certain extent, runoff, without however, prevent the evacuation of the ozone released by the operation of the spark gap, for which small lateral vents 11 are provided.

On décrira maintenant la variante prévue pour le logement de la grille G3 illustrée par les figures 4 et 5.We will now describe the variant provided for housing the grid G3 illustrated in FIGS. 4 and 5.

Suivant cette variante, il est possible d'inclure également dans le connecteur le moyen de connexion de la grille G3 au circuit d'alimentation correspondant lorsque la broche reliée à cette dernière est suffisamment distante des autres broches les plus proches, comme c'est le cas par exemple pour certains culots de tubes.According to this variant, it is possible to also include in the connector the means of connection of the grid G3 to the corresponding supply circuit when the pin connected to the latter is sufficiently distant from the other nearest pins, as is the case for example for certain tube caps.

On obtient ainsi un connecteur permettant d'assurer toutes les connexions requises pour un tel tube, avec le maximum de sécurité.A connector is thus obtained making it possible to ensure all the connections required for such a tube, with the maximum of security.

Sur les figures 4 et 5 ,les éléments identiques à ceux des figures 1 et 3 portent les mêmes références que sur ces dernières.In FIGS. 4 and 5, the elements identical to those of FIGS. 1 and 3 have the same references as on the latter.

Sur la figure 4, la référence 12 désigne un moyen de contact pour l'une des broches et son éclateur associé.In FIG. 4, the reference 12 designates a contact means for one of the pins and its associated spark gap.

A la périphérie du connecteur 20 en matière isolante est prévu un bossage perforé 21 dans lequel est maintenu en place un moyen de contact tel qu'à lame, pénétrant par l'extrémité 22, tandis que la broche reliée à la grille G3 du tube est insérée dans ce bossage par l'extrémité 23. La partie 23 guide mécaniquement et dans un sens la broche de la grille G3 en réaction avec la force d'application du contact à lame reliant celle-ci au circuit d'alimentation.At the periphery of the connector 20 made of insulating material is provided a perforated boss 21 in which is held in place a contact means such as a blade, penetrating through the end 22, while the pin connected to the grid G3 of the tube is inserted into this boss by the end 23. The part 23 mechanically guides and in one direction the pin of the grid G3 in reaction with the force of application of the blade contact connecting the latter to the supply circuit.

Le moyen de connexion de la grille G3 au circuit d'alimentation peut aussi bien être un contact à lame relié à celui- ci par l'intermédiaire d'un conducteur à haut isolement, avec interposition d'éclateur et résistante indépendants, qu'un connecteur du type à éclateur et résistance incor- porés .The means of connection of the grid G3 to the supply circuit can be either a blade contact connected to the latter via a conductor with high insulation, with interposition of spark gap and independent resistors, as well as type connector spark gap and resistance incor- p gilding.
