Abstract
Description
L'invention se rapporte à un système de déviation des faisceaux électroniques pour tube à rayons cathodiques, et plus particulièrement à l'assemblage de ses éléments constitutifs et à sa fixation sur le col du tube.The invention relates to a system for deflecting electron beams for cathode ray tubes, and more particularly to the assembly of its constituent elements and to its attachment to the neck of the tube.
Un tel système de déviation est généralement constitué d'une paire de bobines de déviation verticale, d'une paire de bobines de déviation horizontale et d'un anneau de forme sensiblement tronconique en matériau magnétique destiné à concentrer le flux créé par les bobines. Les deux paires de bobines de déviation sont isolées électriquement par un séparateur, généralement en matière plastique, lequel permet en outre d'améliorer la rigidité mécanique du dispositif de déviation, de fixer les bobines les unes par rapport aux autres et d'ajuster l'ensemble sur le col du tube. Le séparateur est constitué d'un corps principal, en une ou plusieurs parties, sensiblement en forme d'entonnoir, et d'une partie arrière flexible épousant le col du tube et destinée à fixer la position du système de déviation selon l'axe longitudinal du tube; cette fixation est généralement opérée grâce à un collier de serrage disposé au-dessus de la partie arrière flexible.Such a deflection system generally consists of a pair of vertical deflection coils, a pair of horizontal deflection coils and a ring of substantially frustoconical shape made of magnetic material intended to concentrate the flux created by the coils. The two pairs of deflection coils are electrically insulated by a separator, generally made of plastic, which also makes it possible to improve the mechanical rigidity of the deflection device, to fix the coils relative to each other and to adjust the together on the neck of the tube. The separator consists of a main body, in one or more parts, substantially in the form of a funnel, and a flexible rear part conforming to the neck of the tube and intended to fix the position of the deflection system along the longitudinal axis. tube; this fixing is generally effected by means of a clamping collar placed above the flexible rear part.
Dans le cas ou les bobines sont en forme de selle, l'assemblage des différents éléments constitutifs du système de déflexion se déroule de la façon suivante:
- les bobines de déflexion horizontale sont d'abord disposées à l'intérieur du séparateur et généralement maintenues à sa place par clipsage et/ou collage
- les bobines de déflexion verticales sont ensuite disposées sur la partie externe du séparateur; la fixation de leur partie avant est souvent réalisée en introduisant cette partie dans un logement prévu sur le séparateur
- enfin l'anneau en matériau ferromagnétique vient sur les bobines de déflexion verticale qu'il recouvre partiellement
- le corps principal et l'anneau arrière amovible comportent des moyens de verrouillage permettant de les solidariser l'un à l'autre
- l'anneau arrière amovible comporte des moyens de maintien de la partie arrière des bobines de déflexion verticale En outre, l'anneau arrière assure le maintien de l'arrière des bobines de déflexion verticale en venant le recouvrir grâce à des moyens disposés sur la périphérie du dit anneau. L'invention sera mieux comprise à l'aide des dessins, parmi lesquels:
- les figures 1 et 2 représente des systèmes de déflexion selon l'état de la technique
- la figure 3 représente un système de déflexion selon l'invention
- la figure 4 est la représentation de face dans le plan XY de l'anneau arrière du séparateur
- la figure 5 est une vue en coupe suivant un plan contenant l'axe Z du dispositif de déflexion assemblé
- la figure 6 est une vue en coupe suivant le plan YZ de l'anneau arrière du séparateur
- les figures 7A et 7B représentent de face et en coupe les moyens permettant le maintien en position de l'anneau en matériau ferromagnétique
- les figures 8A et 8B représentent de face et en coupe les moyens permettant le maintien de la partie arrière des bobines de déflexion verticale
- the horizontal deflection coils are first placed inside the separator and generally held in place by clipping and / or gluing
- the vertical deflection coils are then placed on the external part of the separator; the fixing of their front part is often carried out by introducing this part into a housing provided on the separator
- finally the ring of ferromagnetic material comes on the coils of vertical deflection which it partially covers
- the main body and the removable rear ring include locking means making it possible to secure them to one another
- the removable rear ring includes means for holding the rear part of the vertical deflection coils In addition, the rear ring maintains the rear of the vertical deflection coils by covering it by means arranged on the periphery of the said ring. The invention will be better understood using the drawings, among which:
- Figures 1 and 2 show deflection systems according to the state of the art
- FIG. 3 represents a deflection system according to the invention
- Figure 4 is the front view in the XY plane of the rear ring of the separator
- Figure 5 is a sectional view along a plane containing the Z axis of the assembled deflection device
- Figure 6 is a sectional view along the plane YZ of the rear ring of the separator
- FIGS. 7A and 7B show from the front and in section the means allowing the ring in ferromagnetic material to be held in position
- FIGS. 8A and 8B show from the front and in section the means allowing the rear part of the vertical deflection coils to be maintained
Dans un autre mode de réalisation connu, représenté à la figure 2, le maintien en position des bobines de déflexion verticale et de l'anneau en matériau ferromagnétique est accompli grâce à une couronne 13, venant se fixer sur des rails 10 disposés sur la partie sensiblement cylindrique du séparateur 2; ce séparateur est par ailleurs muni des pieds, dont les logements 11 sont représentés sur la figure, ainsi que d'une couronne élastique 14 permettant la fixation du dispositif de déflexion 1 sur le col du tube grâce à un collier de serrage disposé autour de 14. La couronne 13 vient glisser dans les rails 10 jusqu'à plaquer les bobines de déflexion verticale contre l'avant du séparateur; une étape de collage de la couronne 13 vient parfaire l'immobilisation de l'ensemble. Ce dispositif ne peut cependant être utilisés de façon fiable que pour l'assemblage de bobines de déflexion verticale de type toroïdal, c'est-à-dire bobinées sur l'anneau en matériau ferromagnétique; Dans ce cas la couronne 13 maintien mécaniquement à la fois les bobines de déflexion verticales et l'anneau en matériau ferromagnétique. Dans le cas de bobines en forme de selle, comme représentées sur la figure 1, les bobines 4 s'étendent le long de l'axe Z sur une longueur supérieure à celle de l'anneau 5; un dispositif comme représenté dans la figure 2 ne pourrait pas assurer le maintien mécanique de l'anneau 5.In another known embodiment, represented in FIG. 2, the maintenance in position of the vertical deflection coils and the ring of ferromagnetic material is accomplished by means of a
La figure 3 est une illustration d'un dispositif de déflexion selon l'invention : le séparateur comporte deux parties distinctes l'une de l'autre, un corps principal 26 dont au moins une partie est de forme évasée et une partie arrière 20 venant se solidariser à la précédente par des moyens décrits plus loin; différents moyens sont solidaires de la partie arrière 20 :
- des
bras 21 s'étendent longitudinalement vers la partie évasée du séparateur pour venir effleurer l'anneau en matériau ferromagnétique 5 - des pattes flexibles 22 recouvrent la partie arrière des
bobines 25 de déflexion verticale - des pattes flexibles 23, disposées sur la périphérie de la partie de 20 la plus éloignée de l'avant du séparateur, sont recouvertes d'un anneau de
serrage 24; l'ensemble permet la fixation du dispositif de déflexion sur le col du tube.
-
arms 21 extend longitudinally towards the flared part of the separator to touch the ring offerromagnetic material 5 -
flexible tabs 22 cover the rear part of thecoils 25 of vertical deflection -
flexible tabs 23, disposed on the periphery of the part furthest from the front of the separator, are covered with aclamping ring 24; the assembly allows the fixing of the deflection device on the neck of the tube.
Dans un mode de réalisation de l'invention, la partie arrière amovible, de forme sensiblement annulaire 20 est représentée de face à la figure 4. La même pièce est représentée à la figure 5, en coupe radiale suivant l'axe AA passant par les pattes flexibles 22, lorqu'elle est mise en place dans le système de déflexion 1. La solidarisation du corps principal 26 et de la partie arrière amovible 22 s'opère grâce à des pattes flexibles 60, disposées sur la périphérie interne de 22 et s'étendant vers la partie évasée du séparateur; ces pattes 60 sont munies d'ouvertures venant s'encliqueter sur des ergots 61 disposés sur la surface interne 62 de la partie principale 2 du séparateur. Les ergots sont disposés de telle façon que l'encliquetage des pattes 60 et des ergots 61 s'effectue lorsque la partie arrière 22 vient en butée sur le corps principal 2, ceci afin d'optimiser la rigidité mécanique de l'ensemble. Pour maintenir en place l'arrière des bobines de déflexion verticale 25, des pattes flexibles 22 sont disposées sur la périphérie externe de la partie 20 de manière à recouvrir partiellement ces bobines. Comme illustré en détail par les figure 8A et 8B, ces pattes comportent en outre sur leur surface interne une protubérance 30 destinée à exercer une pression sur l'arrière des bobines 25 afin de les maintenir, sans les endommager, plaquées contre le corps du séparateur. Les pattes 22 sont réparties de façon homogène sur la périphérie de la couronne 20; dans un mode de réalisation de l'invention, ces pattes sont au nombre de 6, réparties régulièrement tous les 60°.In one embodiment of the invention, the removable rear part, of substantially
Pour réaliser le maintien de l'anneau en matériau ferromagnétique 5, la partie arrière 20 du séparateur possède des bras 21, disposés sur sa périphérie et s'étendant vers la partie évasée du séparateur. La longueur de ces bras est telle que ces derniers viennent au contact de l'anneau 5, compte tenu des tolérances admissibles sur la longueur du dit anneau, lorsque l'anneau est en butée sur l'avant du dispositif de déflexion. Ces bras sont au nombre minimum de 3 pour éviter tout basculement de l'anneau 5. Dans un mode de réalisation de l'invention on a choisi d'immobiliser l'anneau 5 grâce à 4 bras répartis régulièrement sur la périphérie externe de la partie arrière 20, tous les 90°.To hold the
Pour optimiser le rapport entre les poids de matière et la rigidité mécanique des bras 21, ces derniers peuvent avoir une section en forme de U comme indiqué sur la figure 6 montrant en coupe longitudinale la partie arrière 20 du séparateur.To optimize the ratio between the material weights and the mechanical rigidity of the
Pour parfaire le maintien de l'anneau en matériau ferromagnétique, il est possible de procéder à une phase de collage. Pour cela, comme indiqué sur la figure 6, et plus en détail sur les figures 7A et 7B, l'extrémité des bras 21 possèdent une ouverture 40 destinée au passage de la colle devant faire adhérer l'extrémité du bras à l'arrière de l'anneau 5; la forme en U participe au guidage de la colle vers l'extrémité 40.To complete the retention of the ferromagnetic material ring, it is possible to carry out a bonding phase. For this, as indicated in FIG. 6, and in more detail in FIGS. 7A and 7B, the end of the
Dans un mode de réalisation préférentiel, la fixation du dispositif de déflexion sur le col du tube est réalisé par un collier de serrage 24 disposé au dessus des pattes flexibles 23. Comme indiqué sur la figure 5, la flexibilité des pattes 23 est realisée au niveau de l'attache 50 de ces pattes à la périphérie interne de l'anneau arrière 20 : la forme de ces attaches est sensiblement en forme de esse. Cette forme spécifique présente l'avantage suivant lors du réglage du système de déflexion sur le col du tube:
- la position le long de l'axe Z une fois fixée par le serrage du
collier 24, il est souvent nécessaire de basculer le système de déviation dans le plan XZ et/ou dans le plan YZ afin d'optimiser le positionnement des axes des champs avec l'axe du canon à électrons et l'axe principal Z du tube - la
zone 50 permet d'absorber les contraintes liées au basculement du système de déflexion sans les transmettre aux pattes 23 : de cette façon la position en Z du système de déflexion ne subit pas de modification pendant le réglage final de sa position sur le col du tube.
- the position along the Z axis once fixed by tightening the
collar 24, it is often necessary to tilt the deflection system in the XZ plane and / or in the YZ plane in order to optimize the positioning of the field axes with the axis of the electron gun and the main axis Z of the tube - the
zone 50 makes it possible to absorb the stresses linked to the tilting of the deflection system without transmitting them to the legs 23: in this way the Z position of the deflection system does not undergo any modification during the final adjustment of its position on the neck of the tube.
