| Zusammenfassung: | When the pyrotechnical cartridge or motor (5) is actuated by electrical ignition from its head (5c), it pushes back the insulating piston (3) which separates by shearing the intermediary connection portion (1b) of the destructible lead (1) and pushes it back into the bore (1e) with the rod (9) of which the conic end (9a) wedges into the plug (10) for forming brake. The fuse cartridges (13) cut off safely the circuit. Application to electric circuit shut off, for example under the effect of overcurrent detectors.
Lorsque la cartouche ou moteur pyrotechnique (5) est mis en action par allumage electrique a partir de sa tete (5c), elle repousse le piston isolant (3) qui separe par cisaillement la partie intermediaire de liaison (1b) du conducteur destructible (1) et la repousse dans l'alesage (1 e) avec la tige (9) dont l'extremite conique (9a) vient se coincer dans le bouchon (10) pour former frein. Les cartouches fusibles (13) coupent alors le circuit en toute securite. Application a la coupure de circuits electriques, par exemple sous l'effet de detecteurs de surintensite. |
