Abstract
The utility model discloses a circuit breaker with an adjustable rated breaking current and aims to provide a circuit breaker of which the rated breaking current can be adjusted so as to adapt to different circuits. The circuit breaker comprises a base and a housing, wherein the housing is buckled on the base, a potentiometer is arranged on the housing, a rotating shaft is arranged on the potentiometer, the rotating shaft is connected with a knob, an annular connection plate is sheathed outside the rotating shaft, and a plurality of wiring terminals extending along the direction perpendicular to the rotating shaft are arranged at the outer circumference of the annular connection plate. The main purpose of the utility model is to provide a circuit breaker of which the rated breaking current can be adjusted so as to adapt to different circuits.
Description
Technical field
The utility model relates to a kind of circuit breaker of regulating rated interrupting current.
Background technology
At present, in the modern production field of circulation, circuit breaker be a kind of overload and during short circuit automatically the blocking-up short circuit to protect the electric equipment of short circuit and load equipment.It is very extensive that circuit breaker is used, but the turn-off current of normal circuit breaker fix, can not regulate as required, versatility is poor, has brought inconvenience to the user.
Chinese patent Granted publication number: 201490125U, at on 05 26th, 2010 Granted publication day, a kind of low-voltage circuit breaker is disclosed, it is combined by wind circuit breaker processed and refrigeration circuit breaker, the wind circuit breaker handle connecting rod processed lower right corner is shaped with a small gap, the refrigeration circuit breaker handle lower left corner is shaped with a protrusion, and small gap and protrusion coincide.The weak point of its existence is, the rated interrupting current of circuit breaker is fixed, and can not regulate as required, and versatility is poor.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art, a kind of circuit breaker of regulating rated interrupting current to be provided, can regulating the different circuit of rated interrupting current adaptation of circuit breaker.
To achieve these goals, the utility model is by the following technical solutions: a kind of circuit breaker of regulating rated interrupting current, comprise base, shell, described shell is buckled on the base, be provided with potentiometer at described shell, be provided with rotating shaft at potentiometer, rotating shaft links to each other with knob, outside described rotating shaft, be arranged with annular tab, be provided with the binding post that extend perpendicular to rotor shaft direction on some edges at the outer circumference surface of described annular tab.Rotating shaft is linked to each other with knob, thereby be the rated current of regulating circuit breaker for the ease of the user by regulator potentiometer, adapt to the demand of different user.Be arranged with annular tab outside described rotating shaft, the outer circumference surface of annular tab is provided with the binding post that extend perpendicular to rotor shaft direction on some edges, is for the ease of wiring, makes things convenient in the potentiometer access circuit breaker.
As preferably, described knob is provided with scale.Knob be provided with scale be convenient to the user according to scale on the standard figures rated current of regulating circuit breaker, adapt to the needs of different circuit.
As preferably, described binding post and annular tab are integrated.Binding post and annular tab are made as integrated, are convenient to processing, reduced the technique of processing, provide cost savings.
Therefore, the utlity model has following beneficial effect: the rated interrupting current that can regulate circuit breaker adapts to different circuit.
