Description
La présente invention concerne le domaine des câbles électriques, et en particulier les câbles électriques à âme conductrice souple. L'invention concerne également les transformateurs haute tension qui sont équipés de câbles électriques haute tension pour par exemple alimenter électriquement des composants électriques à l'intérieur d'un appareil électronique, tel qu'un téléviseur.The present invention relates to the field of cables electrical cables, and in particular electrical cables with conductive core flexible. The invention also relates to high transformers voltage which are fitted with high voltage electrical cables for par example electrically supply electrical components to inside an electronic device, such as a TV.
Dans le domaine des transformateurs haute tension, la connexion électrique entre les sorties hautes tension du transformateur et les câbles électriques haute tension de sortie était pendant longtemps un problème technique délicat à résoudre.In the field of high voltage transformers, the electrical connection between the high voltage outputs of the transformer and the high voltage output electrical cables was for a long time a delicate technical problem to solve.
On connaít récemment par le brevet européen n° 0 236 642 une solution simple et satisfaisante à ce problème. Il s'agit d'introduire dans le boítier isolant du transformateur des pastilles souples en silicone chargé de poudre conductrice qui constituent une interface de connexion électrique entre les sorties haute tension des enroulements du transformateur et les câbles haute tension de sortie. Il suffit d'enfoncer les extrémités des conducteurs dans les pastilles en silicone chargé de poudre conductrice pour assurer la connexion électrique entre ces conducteurs.We know recently from the European patent n ° 0 236 642 a simple and satisfactory solution to this problem. This is to introduce in the insulator box of the transformer, flexible silicone pads loaded with conductive powder which constitute a connection interface between the high voltage outputs of the windings of the transformer and high voltage output cables. Just press the ends of the conductors in the silicone pellets charged with conductive powder to ensure the electrical connection between these conductors.
Cette solution ne peut être mise en oeuvre de manière fiable que si les conducteurs qui sont enfoncés dans les pastilles conductrices sont suffisamment rigides pour être assemblés de façon amovible (et répétitive en cas de besoin) dans les pastilles conductrices de connexion. Les câbles utilisés selon ce brevet antérieur sont à âme rigide. This solution cannot be reliably implemented only if the conductors which are embedded in the conductive pads are rigid enough to be removably assembled (and repetitive if necessary) in the conductive pads of connection. The cables used according to this earlier patent have a core rigid.
Cependant, il peut être souhaitable voire avantageux dans certaines circonstances d'utiliser des câbles à âme souple au lieu des câbles à âme rigide. C'est par exemple le cas lorsque le transformateur haute tension est utilisé dans un emplacement réduit (à l'intérieur d'un poste de télévision par exemple), car les câbles souples sont plus maniables que les câbles rigides. De plus, étant donnée la haute tension (pouvant aller jusqu'à 50 Kvolts), les normes de sécurité exigent que le boítier isolant du transformateur comporte des cheminées de sécurité qui séparent, d'une part les points de connexion (pastilles conductrices par exemple) entre les sorties haute tension des enroulements du transformateur et les extrémités des câbles haute tension de sortie, et d'autre part le milieu environnant, d'une certaine distance se traduisant par la hauteur des cheminées. Les câbles haute tension sortant de ces cheminées augmentent plus ou moins l'encombrement du transformateur dans le prolongement des cheminées selon la souplesse des câbles. Plus les câbles sont souples, plus on peut réduire l'encombrement supplémentaire du transformateur haute tension causé par les câbles de sortie.However, it may be desirable or even advantageous in certain circumstances of using flexible core cables instead of rigid core cables. This is for example the case when the transformer high voltage is used in a reduced location (inside a television set for example), because flexible cables are more easier to handle than rigid cables. In addition, given the high voltage (up to 50 Kvolts), safety standards require that the transformer insulator box has safety chimneys which separate, on the one hand the connection points (conductive pads by example) between the high voltage outputs of the windings of the transformer and the ends of the high-voltage output cables, and on the other hand the surrounding environment, from a certain distance translating by the height of the chimneys. The high voltage cables coming out of these chimneys more or less increase the size of the transformer in the extension of the chimneys according to the flexibility of the cables. More the cables are flexible, the more the space can be reduced additional high voltage transformer caused by the cables of exit.
Il peut être envisagé d'associer à l'âme souple d'un câble dénudé une cosse électrique sertie sur la gaine du câble, afin de permettre l'utilisation du câble souple dans les transformateurs haute tension munis de pastilles conductrices de connexion. Mais la cosse électrique crée un encombrement radial au câble qui peut être genant dans certaines techniques, notamment celle du clipsage de câble selon le brevet européen n° 0 236 642.It can be envisaged to associate with the flexible core of a cable stripped an electrical terminal crimped on the sheath of the cable, in order to allow the use of flexible cable in high transformers voltage fitted with conductive connection pads. But the pod electric creates a radial space in the cable which can be annoying in certain techniques, in particular that of cable clipping according to the European Patent No. 0 236 642.
La présente invention a pour objet de proposer une solution simple et efficace permettant de rigidifier l'âme conductrice souple des câbles électriques pour être utilisée notamment dans des transformateurs haute tension munis de pastilles conductrices de connexion.The object of the present invention is to propose a solution simple and effective to stiffen the flexible conductive core of electric cables to be used in particular in high voltage transformers fitted with conductive pads of connection.
L'invention a également pour objet un procédé de fabrication d'un connecteur rigide pour câble électrique à âme conductrice souple. The invention also relates to a manufacturing process a rigid connector for electric cable with flexible conductive core.
L'invention a en outre pour objet un câble électrique à âme souple dont au moins une extrémité est rigidifiée d'une façon particulière.The invention further relates to an electric cable with a core flexible with at least one end rigidified in a way particular.
L'invention a encore pour objet un transformateur haute tension équipé de câbles électriques souples dont une extrémité de l'âme est rigidifiée de façon à permettre son enfoncement aisé dans les pastilles conductrices de connexion du transformateur.The invention also relates to a high transformer tension fitted with flexible electrical cables, one end of the core is stiffened so as to allow its easy insertion into the conductive transformer connection pads.
Le procédé de fabrication d'un connecteur associé à un câble électrique à âme conductrice souple, selon l'invention, consiste à dénuder une extrémité du câble en enlevant la gaine plastique de protection autour de l'âme conductrice souple, à fixer à l'extrémité dénudée du câble en butée axiale contre la gaine, un disque métallique qui a un diamètre inférieur ou égal au diamètre de la gaine et qui est muni d'un trou central traversé par l'âme conductrice souple, et à rigidifier l'âme conductrice souple par une soudure conductrice qui rend également l'âme solidaire du disque métallique.The method of manufacturing a connector associated with a cable electric with flexible conductive core, according to the invention, consists of strip one end of the cable by removing the plastic sheath protection around the flexible conductive core, to be fixed at the end stripped of the cable in axial abutment against the sheath, a metal disc which has a diameter less than or equal to the diameter of the sheath and which is provided with a central hole through which the flexible conductive core passes, and stiffen the flexible conductive core by a conductive weld which makes also the soul attached to the metal disc.
Selon l'invention, on fournit un câble électrique à âme conductrice souple entourée par une gaine isolante en matière plastique. Le câble comporte une extrémité dénudée par enlèvement de la gaine autour de l'âme, un disque métallique de diamètre inférieur ou égal au diamètre de la gaine et qui est pourvu d'un trou central traversée par l'âme du câble, le disque étant en butée axiale contre la gaine. Un dépôt de soudure conductrice sur l'âme dénudée rigidifie l'âme tout en la rendant solidaire mécaniquement du disque métallique.According to the invention, an electrical cable with a core is provided flexible conductor surrounded by an insulating plastic sheath. The cable has a stripped end by removing the sheath around the core, a metal disc with a diameter less than or equal to diameter of the sheath and which is provided with a central hole through which the cable core, the disc being in axial abutment against the sheath. A deposit of conductive solder on the stripped core stiffens the core while mechanically joining the metal disc.
De préférence, le disque comporte des picots sur la surface orientée vers la gaine et qui s'enfoncent dans la gaine pour assurer le maintien au moins provisoire du disque sur le câble. Les picots peuvent être obtenus par estampage du disque et peuvent être régulièrement répartis sur un cercle concentrique au trou central du disque. Avantageusement, le trou central est délimité par un col tronconique qui assure le centrage du disque autour de l'âme et renforce la cohésion mécanique de l'ensemble une fois recouvert de soudure. Preferably, the disc has pins on the surface oriented towards the sheath and which sink into the sheath to ensure the at least temporary maintenance of the disc on the cable. The pins can be obtained by stamping the disc and can be regularly distributed on a circle concentric with the central hole of the disc. Advantageously, the central hole is delimited by a frustoconical neck which ensures the centering of the disc around the core and strengthens the cohesion mechanical assembly once covered with solder.
Selon l'invention, on obtient un transformateur haute tension comportant un bobinage enfermé dans un boítier isolant, des pastilles souples conductrices dans lesquelles sont enfoncés les conducteurs de sortie du bobinage, et des câbles souple haute tension dont les extrémités dénudées sont rigidifiées comme indiqué ci-dessus pour être enfoncées aisément dans les pastilles conductrices.According to the invention, a high voltage transformer is obtained comprising a winding enclosed in an insulating housing, pellets flexible conductive in which the conductors of output of the winding, and flexible high voltage cables whose stripped ends are stiffened as shown above to be easily inserted into the conductive pads.

l'invention apparaítront à l'étude de la description détaillée d'un exemple
de réalisation particulier non limitatif et illustré sur des dessins annexés :
La figure 1 montre un transformateur haute tension du type
décrit dans le brevet européen n° 0 236 642 avec des câbles haute
tension à âme souple. Le transformateur 1 peut être utilisé pour
alimenter le tube cathodique d'un téléviseur et comporte un circuit
magnétique 2, un bobinage 3 à plusieurs enroulements, et des broches 4
de connexion électrique entre le bobinage 3 et un autre composant
électrique non représenté. Le bobinage 3 comporte deux sorties haute
tension dont l'une alimente, via un bloc potentiométrique non représenté
les grilles du tube cathodique non représenté, et dont l'autre alimente
l'anode du tube cathodique. Des câbles souples haute tension 5 et 6
assurent l'alimentation en hautes tensions issues des deux sorties du
bobinage 3.Figure 1 shows a high voltage transformer of the type
described in European Patent No. 0 236 642 with high cables
tension with flexible core.
Le bobinage 3 comporte une enveloppe protectrice en résine
qui comporte deux cheminées 7, 8 de sécurité destinées à recevoir les
extrémités dénudées rigidifiées 5a et 6a des câbles 5 et 6
respectivement (la rigidification des extrémités dénudées est décrite ci-après).
La hauteur des cheminées 7, 8 est déterminée en fonction de la
haute tension de sortie correspondante. Chaque cheminée 7, 8 comporte
intérieurement à son embase une pastille souple 9 en silicone chargé de
poudre conductrice permettant la connexion électrique entre une sortie
haute tension 10 du bobinage 3 et l'extrémité rigidifiée 5a du câble 5
correspondant. La connexion électrique entre la sortie 10 et l'extrémité
dénudée 5a du câble 5 se fait par enfoncement de l'extrémité 5a et du
conducteur de sortie 10 dans la pastille conductrice 9.Winding 3 has a protective resin casing
which has two
Avantageusement, dans la face inférieure de la pastille
conductrice 9 est enfoncée également l'extrémité d'un conducteur 11
issue d'une résistance de charge 12 dite "bleeder". Il en est de même
pour la pastille conductrice non représentée liée à la cheminée 8.Advantageously, in the underside of the
Afin d'assurer le maintien mécanique des câbles haute tension
5, 6 dans les cheminées 7, 8 contre les mouvements d'arrachements, et
par voie de conséquence assurer la qualité de connexion électrique, on
associe à chaque câble 5, 6 un clip 13, 14 qui coopère avec les
extrémités 15, 16 des cheminées 7, 8 par enclipsage.To ensure the mechanical maintenance of
On se réfère maintenant aux figures 2a et 2b pour expliquer
plus en détail la réalisation des extrémités rigidifiées 5a, 6a des câbles
souple haute tension 5, 6.We now refer to Figures 2a and 2b to explain
in more detail the making of the
Le câble souple 20 comporte une âme conductrice souple 21
toronnée multibrins et une gaine isolante 22 en matière plastique souple
entourant coaxialement l'âme conductrice souple 21. Une extrémité du
câble 20 est dénudée par enlèvement de gaine 22 autour de l'âme
conductrice souple 21. Un disque métallique 23 plat de faible épaisseur
présente un diamètre inférieur ou égal au diamètre de la gaine 22 et un
trou central 24 délimité par un col tronconique 25, ainsi que plusieurs
picots 26 obtenus par estampage du disque 23. Les picots 26 sont de
préférence répartis régulièrement sur un trajet circulaire concentrique au
trou central 24 et dirigés perpendiculairement au plan du disque dans
une direction à l'opposé du col tronconique 25.The
On enfile axialement l'âme conductrice souple 21 du câble 20
dans le trou central 24. Le disque 23 avec ses picots 26 dirigés
axialement se rapproche de la gaine 22 du câble 20. Les picots 26
s'enfoncent ensuite axialement dans la gaine 22 jusqu'à ce que le disque
23 soit en butée axiale contre la gaine 22 (la distance séparant la gaine
22 et le disque 23 sur la figure 2b est artificiellement dessinée pour
mieux distinguer ces deux éléments). L'enfoncement des picots dans la
gaine 22 permet une bonne fixation du disque 23 sur le câble 20, le col
tronconique 25 permettant de centrer le disque 23 autour de l'âme
conductrice souple 21.The flexible
On dépose ensuite une soudure conductrice, par exemple au
moyen d'un brasage à l'aide d'un alliage étain-plomb sur l'âme
conductrice souple 21. La soudure à l'état liquide chaud s'infiltre par
capillarité dans les espaces disponibles du toron multibrins constituant
l'âme conductrice souple et recouvre le col tronconique 25, si bien qu'au
refroidissement de la soudure, d'une part on obtient une extrémité
conductrice 27 rigidifiée du câble 20 issue de l'âme conductrice souple
21 et d'autre part un soudage rendant solidaire le disque métallique 23
et l'extrémité conductrice 27. Le connecteur ainsi obtenu sous forme
d'un T est très résistant au flambement, ce qui améliore les
caractéristiques mécaniques à l'enfoncement amovible du câble 20 dans
la pastille conductrice 9.A conductive solder is then deposited, for example at
using solder-lead alloy on the core
flexible conductive 21. Welding in the hot liquid state seeps through
capillarity in the available spaces of the multi-stranded strand constituting
the flexible conductive core and covers the

diamètre de la gaine 22 du câble 20 permet l'utilisation du système de
clipsage 13 à 16 tel que montré à la figure 1.The choice of the diameter of the
