Abstract

The straight line potentiometer includes several resilient grips which are situated at opposite ends of a line of a carrier. The line is perpendicular to a transverse axis formed by toes on the ends of resilient lugs. The grips engage lateral sectors of a slider in a riding arrangement. The slider has a central offset portion which is inserted between the lugs of the carrier. The offset portion is recessed. The resilient grips are in two pairs facing each other. The grips are in the same plane as the toes.

PERFECTIONNEMENTS APPORTES A UN POTENTIOMETRE RECTILIGNE  IMPROVEMENTS TO A RECTILINEAR POTENTIOMETER

L'invention se rapporte à des perfectionnements apportés à un potentio-  The invention relates to improvements made to a potentio-

mètre rectiligne du type miniature et de ceux utilisés dans les appareils électroniques, lesdits perfectionnements apportant une fiabilité plus grande,  rectilinear meter of the miniature type and of those used in electronic devices, said improvements bringing greater reliability,

une simplicité de montage et un meilleur coût de fabrication.  simplicity of assembly and better manufacturing cost.

Les potentiomètres rectilignes conventionnels comprennent en général un boîtier pourvu d'une ouverture longitudinale de chaque côté de laquelle  Conventional rectilinear potentiometers generally include a housing provided with a longitudinal opening on each side of which

se trouve au moins une piste électro-conductrice d'un côté et une électro-  there is at least one electrically conductive track on one side and an electrically

résistive de l'autre, parallèles entre elles, ainsi qu'un support,avec une tige ou appendice de commande,susceptible d'un déplacement rectiligne le long de ladite ouverture, ledit support comportant une ou plusieurs pièces électro-conductrices ou curseurs qui établissent des ponts électriques  resistive on the other, parallel to each other, as well as a support, with a control rod or appendage, capable of rectilinear displacement along said opening, said support comprising one or more electrically conductive parts or sliders which establish electric bridges

entre différents points desdites pistes.  between different points of said tracks.

Dans une solution connue de l'état de la technique,la liaison dudit support du curseur au boîtier du potentiomètre s'effectue à partir de deux pattes élastiques appartenant audit support, en forme de fourche, terminées,chacune d'elles, par une griffe, qui se rapprochent lorsqu'elles sont introduites dans ladite ouverture longitudinale et, une fois la face interne de cette dernière dépassée, se séparent de manière à rester retenues par les bords  In a solution known from the prior art, the connection of said cursor support to the potentiometer housing is effected by two elastic tabs belonging to said support, in the form of a fork, each terminated by a claw. , which approach when they are introduced into said longitudinal opening and, once the internal face of the latter exceeded, separate so as to remain retained by the edges

intérieurs de ladite ouverture longitudinale.  interiors of said longitudinal opening.

L'accouplement de la pièce électro-conductrice, qui constitue le curseur, sur lesdites pattes en forme de fourche, est réalisée par ancrage sur des zones planes de fixation, des deux côtés des pattes, opération qui doit s'effectuer à partir d'une robotique de précision, à cause de ses dimensions réduites, ce qui accroît le coût du produit pour garantir une fabrication  The coupling of the electrically conductive part, which constitutes the cursor, on said fork-shaped legs, is carried out by anchoring on flat fixing zones, on both sides of the legs, operation which must be carried out from precision robotics, because of its reduced dimensions, which increases the cost of the product to guarantee manufacturing

correcte du potentiomètre.potentiometer correct.

Néamoins, sur ledit potentiomètre rectiligne, il arrive que si, pour une quelconque intervention sur le circuit, ou pendant l'opération d'ancrage du curseur, lesdites pattes se rejoignent, ou sont déformées à cause de la chaleur, leurs griffes peuvent pénétrer, du moins en partie, dans l'ouverture  Nevertheless, on said rectilinear potentiometer, it happens that if, for any intervention on the circuit, or during the anchoring operation of the cursor, said legs join, or are deformed because of the heat, their claws can penetrate, at least in part, in the opening

sable le fonctionnement du potentiomètre. Et si on essaye de débloquer ledit support en agissant sur lui pour corriger une anomalie, on peut détruire  sand the operation of the potentiometer. And if we try to unlock the said support by acting on it to correct an anomaly, we can destroy

ledit curseur à cause de sa fragilité résultant de ses faibles dimensions.  said cursor because of its fragility resulting from its small dimensions.

La fixation desdites pattes, sur une partie desquelles se fixe le curseur par ancrage, n'est pas dans n'importe quel des cas effective ou sûre et impose dans la plupart des cas des coûts de fabrication onéreux pour obtenir -2-  The fixing of said legs, on a part of which the cursor is fixed by anchoring, is not in any case effective or safe and imposes in most cases expensive manufacturing costs to obtain -2-

un potentiomètre fini adéquate.an adequate finite potentiometer.

L'objet de l'invention consiste à solutionner lesdits inconvénients à partir d'un potentiomètre rectiligne dont les perfectionnements consistent essentiellement à doter le curseur d'une portion, par exemple présentant une inflexion rentrante, qui vient s'intercaler, lors du montage, entre les pattes en forme de fourche du support, empêchant la jonction desdites pattes et leur passage dans l'ouverture du boîtier. Ainsi ledit curseur possède des appendices, de sens opposés, qui pénètrent entre les paires de crochets élastiques du support, avec une action perpendiculaire à celle des griffes ou pattes en forme de fourche, le temps nécessaire pour que lesdits crochets montent sur les bords correspondants du curseur, le retenant fermement sans la nécessité d'effectuer un quelconque type d'ancrage, avec une économie  The object of the invention consists in solving said drawbacks from a rectilinear potentiometer, the improvements of which essentially consist in providing the cursor with a portion, for example having a re-entrant inflection, which is inserted during assembly, between the fork-shaped legs of the support, preventing the junction of said legs and their passage through the opening of the housing. Thus said cursor has appendages, in opposite directions, which penetrate between the pairs of elastic hooks of the support, with an action perpendicular to that of the claws or legs in the form of a fork, the time necessary for said hooks to mount on the corresponding edges of the slider, holding it firmly without the need to perform any type of anchoring, with economy

conséquente dans le coût et une simplicité de mise en place.  consistent in cost and simplicity of installation.

Les caractéristiques et les avantages de l'invention vont apparattre  The characteristics and advantages of the invention will become apparent

plus clairement à la lecture de la description détaillée qui suit d'un mode  more clearly on reading the following detailed description of a mode
