Abstract

L'invention concerne un appareil anti-coincement de poignée de stockage d'énergie de disjoncteur universel, comprenant un corps de disjoncteur, un mécanisme d'actionnement monté sur un côté du corps de disjoncteur, et une poignée de stockage d'énergie montée sur la paroi latérale externe d'un côté du mécanisme d'actionnement. La poignée de stockage d'énergie est mise en rotation pour stocker manuellement de l'énergie dans le mécanisme d'actionnement. Le mécanisme d'actionnement comprend un arbre rotatif en forme de V. Une extrémité de l'arbre rotatif en forme de V fait saillie depuis la paroi latérale sur un côté du mécanisme d'actionnement. Une extrémité de l'arbre rotatif en forme de V est emmanchée avec un cliquet lié à la poignée de stockage d'énergie. Un crampon lié au cliquet est disposé sur le côté de la poignée de stockage d'énergie faisant face au cliquet. La rotation de la poignée de stockage d'énergie fait tourner le cliquet par l'intermédiaire du crampon. Une structure anti-coincement empêchant le crampon et le cliquet de se coincer est disposée entre le crampon et le cliquet. La structure anti-coincement comprend une plaque anti-coincement. Lorsque la poignée de stockage d'énergie se trouve dans un état initial, la plaque anti-coincement sépare le crampon du cliquet.
