Abstract (en)
[origin: CN112490028A] An electrical switching unit (2) having separable contacts includes a switching device (4) including a control lever (18) mechanically coupled to a movable electrical contact (8) and a ballistic lever(26) mounted on the control lever (18) and configured to be displaced to a deployed position to cooperate with a support (24) to prevent the control lever from exiting the position thereof (18). Theswitching device comprises a fixed bearing (30) mounted around the control lever. The bulletproof rod includes a contact portion (28) that contacts an edge of the bearing when the bulletproof rod is in its rest position and that is displaced along the edge when the control rod is rotated about the bearing. The bearing includes, on the edge, a guide portion (34) in the form of a cam configured to push the bulletproof rod into its deployed position.
Abstract (fr)
Un appareil de commutation électrique (2) à contacts séparables, comprend un dispositif de commutation (4) comportant: un levier de commande (18) couplé mécaniquement à un contact électrique mobile (8) et un levier anti-rebond (26), monté sur le levier de commande (18) et configuré pour se déplacer vers une position déployée pour coopérer avec une butée (24) pour empêcher le levier de commande de quitter sa position.Le dispositif de commutation comporte un palier fixe (30) monté autour du levier de commande. Le levier anti-rebond comporte une portion de contact (28) qui est en contact contre un bord du palier lorsque le levier anti-rebond est dans sa position de repos et qui se déplace le long dudit bord lorsque le levier de commande tourne autour du palier. Le palier comporte, sur ledit bord, une portion de guidage (34) en forme de came configurée pour pousser le levier anti-rebond vers sa position déployée.
