Description

"Fixation d'un élément sensible å la température."
L'invention concerne la fixation d'un élément sensible å la température & un constituant pouvant être chauffé.
"Attachment of a temperature sensitive element."
The invention relates to the attachment of a temperature sensitive element & a heatable component.

Des éléments sensibles å la température sont connus sous de nombreuses formes et avec de nombreuses dimensions. Les éléments envisagés sont du type thermocouple, sont vulnérables et de dimensions tres faibles (d'une longueur aussi faible que quelques millimètres et d'un diamètre de moins de 1 mm). Un problème que posent ces éléments sensibles à la température est leur fixation contre un constituant (une surface) ou å proximité d'un constituant destinés à être soumis b une mesure de température. Il est connu de percer un trou dans le constituant et de fixer l'élément sensible à la température dans ce trou à l'aide d'une colle. Pour diverses raisons, cela peut être non seulement désavantageux, mais aussi difficile. On cite, par exemple, l'obtention de la colle correcte. Celle-ci doit avoir de bonnes propriétés de conduction de chaleur et d'isolation électrique et, en outre elle ne doit pas soumettre l'élément lui-même a des efforts. De plus, la fixation de constituants par une colle dans la fabrication en série présente souvent des inconvénients. Temperature sensitive elements are known in many forms and with many dimensions. The elements envisaged are of the thermocouple type, are vulnerable and of very small dimensions (of a length as short as a few millimeters and of a diameter of less than 1 mm). One problem with these temperature sensitive elements is their attachment to or near a component (surface) intended to be subjected to temperature measurement. It is known to drill a hole in the component and to fix the temperature-sensitive element in this hole using an adhesive. For various reasons, this can be not only disadvantageous, but also difficult. We cite, for example, obtaining the correct glue. This must have good heat conduction and electrical insulation properties and, moreover, it must not subject the element itself to stresses. In addition, the fixing of constituents by an adhesive in mass production often has drawbacks.

L'invention vise å fournir une fixation d'un élément sensible à la température, telle que l'élément soit exempt de contrainte, ctest-å-dire qu'aucune pression n'est exercée sur l'élément å partir de l'extérieur et que l'élément est bien positionné par rapport au constituant chauffe, de sorte que les dimensions sont reproductibles. The invention aims to provide a fixation of a temperature-sensitive element, such that the element is free of stress, that is to say that no pressure is exerted on the element from the outside. and that the element is well positioned relative to the heating component, so that the dimensions are reproducible.

La fixation conforme a l'invention est caractérisée en ce que l'élément sensible & la température, y compris au moins une partie de ses fils de raccordement, est entouré d'une feuille en matériau électriquement isolant et conducteur de la chaleur, 4'élément sensible à la température étant fixé å la feuille dans un boîtier conducteur de la chaleur, au moins l'un des fils de raccordement entourés de la feuille étant serré entre des parties de boîtier et l'élément sensible å la température entouré de la feuille étant enfermé sans contrainte dans le boîtier, boîtier qui présente une surface de contact serrée å conduction de chaleur contre le constituant pouvant être chauffé. The binding according to the invention is characterized in that the temperature-sensitive element, including at least part of its connection wires, is surrounded by a sheet of electrically insulating and heat-conducting material, 4 ' temperature sensitive element being affixed to the sheet in a heat conductive housing, at least one of the connecting wires surrounded by the foil being clamped between housing parts and the temperature sensitive element surrounded by the foil being enclosed without constraint in the housing, the housing which has a tight heat conduction contact surface against the heatable component.

De préférence, le boîtier est muni d'au moins une languette repliée pour serrer les fils de raccordement. Preferably, the housing is provided with at least one folded tab for tightening the connection wires.

Dans ce cas, l'élément sensible & la température peut venir se situer dans un évidement de la languette ou dans un creux du boîtier de façon å être enfermé sans contrainte. In this case, the temperature-sensitive element may come to be located in a recess in the tongue or in a hollow in the housing so as to be enclosed without constraint.

L'invention sera mieux comprise å l'aide de la.  The invention will be better understood using the.

description suivante d'un exemple de réalisation représenté dans le dessin annexé. Dans ce dessin:
La figure 1 est une vue en plan de l'élément sensible å la température, fixé sur un constituant chauffé,
La figure 2 est une coupe transversale suivant la ligne II-II de la figure 1 et
La figure 3 représente un détail d'une fixation légèrement modifiée de l'élément.
Following description of an exemplary embodiment shown in the accompanying drawing. In this drawing:
FIG. 1 is a plan view of the temperature-sensitive element, fixed on a heated component,
Figure 2 is a cross section along line II-II of Figure 1 and
Figure 3 shows a detail of a slightly modified attachment of the element.

Sur les figures, la référence 1 indique l'élément sensible a la température muni de fils de raccordement électrique 2. L'élément sensible å la température avec ses fils de raccordement est entouré d'une feuille 3 ayant de bonnes propriétés d'isolation électrique et de conduction de chaleur, par exemple une feuille "Kapton". Cet ensemble est fixé dans une espèce de boîtier 4 en matériau bien conducteur de la chaleur, par exemple l'aluminium. Le boîtier est muni d'une languette repliée 5 serrant les fils de raccordement entourés de la feuille. La languette 5 présente un évidement 6 dans lequel est situé l'élément sensible å la température 1, de sorte que, en aucune façon, des parties du boîtier sont en contact avec l'élément, c'est-å-dire que l'élément est enfermé sans contrainte dans le boîtier. In the figures, the reference 1 indicates the temperature-sensitive element provided with electrical connection wires 2. The temperature-sensitive element with its connection wires is surrounded by a sheet 3 having good electrical insulation properties and heat conduction, for example a "Kapton" sheet. This assembly is fixed in a kind of housing 4 made of a material which is a good conductor of heat, for example aluminum. The housing is provided with a folded tab 5 tightening the connection wires surrounded by the sheet. The tongue 5 has a recess 6 in which the temperature-sensitive element 1 is located, so that, in no way, parts of the housing are in contact with the element, that is to say that the element is enclosed without constraint in the housing.

De toute évidence, il est également possible, au lieu d'utiliser un évidement dans la languette, de ménager dans le bottier un creux 7 (voir figure 3) servant de logement & l'élément. Une autre possibilité est de diviser le boîtier en deux parties entre lesquelles sont serrés les fils de raccordement, l'élément sensible b la température étant placé dans un creux ou évidement du boiter.  Obviously, it is also possible, instead of using a recess in the tongue, to provide a hollow 7 in the case (see FIG. 3) serving as housing and the element. Another possibility is to divide the housing into two parts between which the connection wires are clamped, the temperature-sensitive element being placed in a hollow or recess in the housing.

De plus, le boîtier 4 présente une surface de contact 8 (par exemple annulaire) fixée contre la surface d'un constituant chauffé 9. A cet effet, le boitier est muni, de part et d'autre de la surface de contact, d'une languette 10 sur laquelle est tendu un fil 11 en acier å ressorts. Les extrémités 12 de chaque fil sont montées derrière une partie de paroi 14 du constituant chauffé 9 en les contournant par une ouverture 13. In addition, the housing 4 has a contact surface 8 (for example annular) fixed against the surface of a heated component 9. For this purpose, the housing is provided, on either side of the contact surface, d 'a tongue 10 on which is stretched a wire 11 of spring steel. The ends 12 of each wire are mounted behind a wall part 14 of the heated component 9, bypassing them through an opening 13.

Dans le mode de réalisation selon les figures, les extrémités 15 des fils de raccordement de l'élément sensible å la température sont reliées å des fils isolés 16 pour un autre raccordement électrique. Dans ces conditions, les liaisons 17 entre les fils sont également entourées de la feuille 3. Les fils isolés 16 sont également fixés au boitier 4, et cela au moyen de languettes repliées 18.  In the embodiment according to the figures, the ends 15 of the connection wires of the temperature-sensitive element are connected to insulated wires 16 for another electrical connection. Under these conditions, the connections 17 between the wires are also surrounded by the sheet 3. The insulated wires 16 are also fixed to the housing 4, and this by means of folded tabs 18.
