Description
Technical field
The present invention relates to electrical technology.
Technical background
Miniature circuit breaker is conventional electrical equipment, and circuit plays a part overload protection and short-circuit protection.Circuit breaker has two kinds of operating states, conducting and disconnections.Along with technical development and the market demand, the state of circuit breaker needs strange land centralized monitor.Circuit breaker manufacturer provides the auxiliary switch module that can match can realize this demand, but the auxiliary switch module that manufacturer provides has 2 weak points, and one is that volume is large, the space of the modulus width taken; Two is that cost is high.
Summary of the invention
The technical problem that the present invention solves is, for deficiency of the prior art, provides a kind of safe, small and exquisite, economic circuit breaker.
Another technical problem that the present invention solves is, provide a kind of with low cost, for detecting the transducer of circuit-breaker status.
The technical scheme that the present invention solve the technical problem employing is, circuit breaker, circuit breaker, comprise shell and shift fork, shift fork has compressing tablet, on shell, the position of shift fork is provided with extending bore, and extending bore is provided with state sensor, and described state sensor comprises fixed part, two electrodes and metal elastic part, one end of metal elastic part is formed with an electrode and is electrically connected, and the other end is in the zone of action of the compressing tablet of shift fork; Another electrode is provided with in the range of movement of metal elastic part.
The fixed part of described transducer comprises two fixed axis arranged side by side, respectively corresponding extending bore and connecting hole; Metal elastic part and electrode are arranged at the fixed axis corresponding to extending bore.Described metal elastic part is coiling wire on one of the electrodes or the torque spring of sheet metal formation, and the range of movement of one end of metal elastic part is limited by another electrode, and this electrode is arranged on the side, elastic force direction of elastomeric element.
When shift fork is in ON position, metal elastic part and two electrode contacts, when shift fork is in OFF position, metal elastic part and an electrode contact;
Or, when shift fork is in ON position, metal elastic part and an electrode contact, when shift fork is in OFF position, metal elastic part and two electrode contacts.
The present invention also provides a kind of breaker state sensor, and comprise fixed part, two electrodes and metal elastic part, electrode is arranged on fixed part, and one end of metal elastic part is fixed on fixed part, is formed be electrically connected with an electrode; The other end is movable end, and the side, elastic force direction of elastomeric element is provided with another electrode.
The invention has the beneficial effects as follows, by the external circuits with Electrode connection, the location status of shift fork can be detected accurately, and then the operating state of circuit breaker detected, especially, transducer major part of the present invention is arranged on circuit breaker internal by the extending bore that circuit breaker is own, therefore there is the advantage of compact, and its structure is simple, failure rate is low, relative to like product, there is advantage significantly with low cost.
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.

Fig. 2,3 is the present invention's schematic diagrames under two states.Wherein a is the schematic diagram under profile status, and b is stereoscopic-state schematic diagram.
Fig. 4 is scheme of installation of the present invention.
The abc tri-width figure of Fig. 5 is the appearance schematic diagram of the circuit breaker being provided with transducer.
Embodiment
See Fig. 1 ~ 4.
Thinking of the present invention is, because the position of shift fork 4 and the state of circuit breaker are one to one, can by the circuit state of shift fork 4 control electrode, short circuit/the off state of electrode in other words, make the operating state of circuit breaker and the short circuit/off state of two electrodes form corresponding relation, the operating state of circuit breaker can be detected by the circuit state of detecting electrode.
Circuit breaker of the present invention is with state sensor 7, and transducer comprises fixed part 1, two electrodes 2 and metal elastic part 3, and metal elastic part 3 is metal torque spring.State sensor 7 is arranged on the connecting hole of circuit breaker by bolt 8.Two electrodes are arranged on fixed part 1, and one end of torque spring 3 is stiff end, is fixed on fixed part 1, or torque spring cover on one of the electrodes, is formed with this electrode and is electrically connected; The other end is movable end; The scope of activities of metal torque spring 3 covers the two kinds of positions making two electric pole short circuits and open circuit.
The fixed part of transducer comprises two fixed axis arranged side by side, respectively corresponding extending bore and connecting hole; Metal elastic part and electrode are arranged on the fixed axis corresponding to extending bore.
Circuit breaker of the present invention comprises shell 5 and shift fork 4, shift fork 4 has compressing tablet 6, the position of shell 1 upper shift fork 4 is provided with extending bore, extending bore is provided with state sensor, described state sensor comprises fixed part 1, two electrodes 2 and metal elastic part 3, one end of metal elastic part 3 is formed with an electrode and is electrically connected, and the other end is in the zone of action of the compressing tablet of shift fork 4; Another electrode is provided with in the range of movement of metal elastic part 3.Fixed part comprises two fixed axis 11,12 arranged side by side, respectively corresponding extending bore 21 and connecting hole 22; Metal elastic part and electrode are arranged at the fixed axis corresponding to extending bore.Connecting hole is that normal circuit breaker is had by oneself, for being linked together by two parts shell of circuit breaker, being generally riveted joint, namely defining connecting hole.Two fixed axis are separately positioned on two holes, ensure that transducer can not produce rotation and cause operational failure.
Compressing tablet alleged by the present invention refers to a part of shift fork, and usual and shift fork is integrated, and as shown in Figure 2 b, it is the structure of circuit breaker self, shift fork and compressing tablet self not inventive point of the present invention.
Concrete, described metal elastic part 3 is coiling wire on one of the electrodes or the torque spring of sheet metal formation, the range of movement of its one end is limited by another electrode, this electrode is arranged on the side, elastic force direction of elastomeric element, when spring is not subject to the power beyond transducer, due to flexible relation, keep all forming circuit with two electrodes and be connected, in other words, short-circuit condition.When spring is subject to external force skew, two electrode open circuits.The pressure that the arrow of Fig. 1 b represents from compressing tablet spring an is departed from electrode.
When the shift fork 4 being provided with the circuit breaker of transducer is in ON position, metal elastic part 3 and two electrode contacts, when shift fork 4 is in OFF position, metal elastic part 3 and an electrode contact;
Or, when shift fork 4 is in ON position, metal elastic part 3 and an electrode contact, when shift fork 4 is in OFF position, metal elastic part 3 and two electrode contacts.
