Abstract
The present invention relates to a circuit breaker which comprises a shell which is internally provided with an operating mechanism, a lock frame, a trip mechanism, a moving contact, a static contact, and a magnetic ring. Two sides in the shell are provided with a wiring terminal and a wiring board. The lock frame is hinged in the shell and comprises a lock part matched with the operating mechanism and an action part matched with trip mechanism. The trip mechanism comprises a trip coil and iron which is hinged in the shell and is arranged in a strip shape. One end of the iron is matched with the trip coil, and the other end of the iron is matched with the action part of the lock frame. The iron is also provided with an elastic piece which applies force to the iron. The force allows one end of the trip coil corresponding to the iron has the trend of separating from the trip coil. The technical scheme of the invention has the advantages of simple and compact structure and high tripping action sensitivity.

By using technique scheme, when tripping coil exceedes elastic component to the active force of profound ferrum to the suction of profound ferrum correspondence tripping coil one end, profound ferrum just rotates around its hinged place, make profound ferrum correspondence snap close frame one end that the operating member of snap close frame is carried out action, and then the snap close of snap close frame is not separated with operating mechanism, just reach dropout purpose.Therefore, technical solution of the present invention, there is simple and compact for structure, the higher technique effect of trip action sensitivity.
The present invention is arranged further: described magnet ring is placed in the middle part of described housing and is positioned at the lower position of described operating mechanism, described tripping coil is that vertical direction is arranged on described magnet ring relative to moving contact opposite side, the hinge point of described profound ferrum is placed in position between described snap close frame and de-mouth coil, described profound ferrum correspondence snap close frame one end arranges the bent over arms of direction, oriented snap close frame side bending, and described bent over arms matches with the operating member of described snap close frame setting.
By using technique scheme so that structure is simpler compact, and further increases trip action sensitivity.
The present invention is arranged further: being provided with in described housing and profound ferrum correspondence is taken off mouth coil one end carry out spacing spacing block set, described spacing block set is placed in described profound ferrum and relatively takes off mouth coil opposite side position.
By using technique scheme, by spacing block set, profound ferrum is carried out spacing, further improve trip action sensitivity.
The present invention is arranged further: described tripping coil includes that yoke and coil, described yoke are fixed by welding in described housing.
By using technique scheme so that structure is more firm.
The present invention is arranged further: described tripping coil is provided with lubricating cup.
By using technique scheme, improve the performance of chopper.
The invention will be further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the closure state structure chart of the embodiment of the present invention；
Fig. 2 is the A portion enlarged drawing of Fig. 1；
Fig. 3 is the malfunction structure chart of the embodiment of the present invention.
Detailed description of the invention
nullSee accompanying drawing 1 to accompanying drawing 3，Chopper disclosed by the invention，Including housing 1，Operating mechanism 2 it is provided with in housing 1、Snap close frame 3、Tripping mechanism 4、Moving contact 5、Static contact 6 and magnet ring，Both sides in housing 1 are also respectively provided with binding post 7 and patch panel 8，Described snap close frame 3 is hinged to be arranged in housing 1，Described snap close frame 3 includes the latch part 301 matched with operating mechanism 2 and the operating member 302 matched with tripping mechanism 4，Described tripping mechanism 4 includes tripping coil，Described tripping mechanism 4 also includes the profound ferrum 402 being hinged in described housing 1，The described elongated setting of profound ferrum 402，Match setting with described tripping coil in described profound ferrum 402 one end，The other end of described profound ferrum 402 matches with the operating member 302 of snap close frame 3 setting，Described profound ferrum 402 is additionally provided with the elastic component 10 that profound ferrum 402 imposes active force，Described active force make the corresponding tripping coil one end of profound ferrum 402 have with tripping coil from trend.The present embodiment is preferred, and described elastic component 10 is set to torsion spring.Operating mechanism 22 includes handle 201, tripping 202, instruction lever 203 and the small rack 204 arranged in linkage.By using technique scheme, when the suction of tripping coil tripping coil one end corresponding to profound ferrum 402 exceedes elastic component 10 to the active force of profound ferrum 402, profound ferrum 402 just rotates around its hinged place, make profound ferrum 402 corresponding snap close frame 3 one end that the operating member 302 of snap close frame 3 is carried out action, and then the snap close of snap close frame 3 is not separated with operating mechanism 2, just reach dropout purpose.Therefore, technical solution of the present invention, there is simple and compact for structure, the higher technique effect of trip action sensitivity.
