Abstract

Cette invention se rapporte à un actionneur linéaire, destiné à être utilisé par exemple au cours du réglage d'articles de meubles, du type comprenant un logement (1) ayant un moteur électrique réversible (2), qui entraîne une broche (4) par l'intermédiaire d'une transmission (3). Sur la broche, il y a un écrou de broche (5), entouré par un tube extérieur (8). L'écrou (5) ne peut tourner et se déplace ainsi dans la direction longitudinale lorsque la broche (4) est mise en rotation. Dans une piste de guidage (13), est montée une carte de circuit imprimé (12) sur laquelle est construit un système de positionnement capacitif. Les capteurs capacitifs (14) du système de positionnement sont activés par le bloc d'activation (15), monté sur l'écrou de broche (5). Simultanément, l'écrou de broche et le bloc d'activation (15), servent à actionner les contacts d'arrêt d'extrémité (16, 17) montés également sur la carte de circuit imprimé (12), lorsque l'écrou de broche (5) atteint une position d'extrémité lors de sa migration sur la broche (4).
