    摘要: An adjusting knob assembly (1) includes a knob member (3) having a knob (7) and an axially extending shaft (15). A support bracket (5) has an aperture (23) defined in part by a gapped ring section (25) formed by a pair confronting arcuate fingers (27). The shaft (15) and the aperture have complimentary, longitudinally extending, circumferentially distributed flat surfaces (17; 33, 35), which provide discrete angular positions for the shaft (15) when the complimentary flat surfaces (17; 33, 35) are in register. Preferably, the gap (29) between the confronting fingers (27) is sized, and the arcuate fingers (27) have a compliance sufficient that the shaft (15) may be passed laterally through the gap (29) and snapped into the aperture (23). Any one of a plurality of interchangeable cam members (43) can be press fit on to the end of the shaft (15).

    摘要: Die Erfindung befaßt sich mit einer Einstellvorrichtung für Auslöser elektrischer Schaltgeräte mit einem äußeren und einem inneren Einstellorgan. Das innere Einstellorgan (40) trägt einen radial abstehenden federnden Rastarm (43), der mit ortsfesten Rastnuten zusammenwirkt. Zur Verbindung mit dem äußeren Einstellorgan (60) ist eine unterbrochene Ringschnappverbindung (46, 51, 64, 65) vorgesehen, die so ausgebildet ist, daß sowohl exzentrische Kräfte als auch von dem federnden Rastarm hervorgerufene unsymmetrische Spreizkräfte und ein Drehmoment übertragen werden können. Hierzu dienen zwei in der Längsachse (56) des Rastarmes (43) hintereinanderliegende größere Zapfen (64) mit einer etwa rechtwinkligen Hinterschneidung und zwei zwischen diesen Zapfen angeordnete kleinere, mit radialen Vorsprüngen versehene Zapfen (65). Diese Vorsprünge besitzen Flanken (73, 74), die in parallel zur Längsachse (54) der Einstellvorrichtung verlaufenden Ebenen (55) liegen. Die Einstellorgane sind im Spritzgußverfahren aus Kunststoff als komplette Teile hergestellt.

    摘要: The present invention discloses a thermal adjustable tripping device for a miniature circuit breaker, which is mounted in a base (101) of the miniature circuit breaker. The thermal adjustable tripping device comprises: a tripping mechanism (106), a thermal deformation element (107) and an adjusting mechanism (102). The tripping mechanism is provided with an extending tripping rod (161). The thermal deformation element is arranged close to the tripping rod and a gap is reserved between the thermal deformation element and the tripping rod. The adjustment mechanism adjusts a distance of the gap between the tripping rod and the thermal deformation element. A current in a loop accessed by the miniature circuit breaker enables the thermal deformation element to generate heat and deform, and the deformed thermal deformation element moves towards the tripping rod, contacts with the tripping rod and pushes the tripping rod to trigger the tripping mechanism to trip. The adjusting mechanism adjusts the distance between the thermal deformation element and the tripping rod so as to adjust a setting current in the loop. The present invention uses a rigid element to adjust a distance between a thermal deformation element and a tripping rod, which can ensure that the distance between the thermal deformation element and the tripping rod is constant in each operation. The tripping device of the present invention is applicable to an electric motor.
