Fig. 6 is the view that moves to the action bars of open position when stator and mover fuse each other in the middle of the electric wire circuit breaker with trip gear of the embodiment of the present invention from off-position.
With reference to figure 1, comprise shut-down mechanism 100, locking component 200, stator 300, mover 400 and link component 500 according to the trip gear of one embodiment of the invention.
As shown in Fig. 2 to Fig. 6, comprise housing 20, interrupter 30, shut-down mechanism 100, locking component 200, stator 300, mover 400 and link component 500 according to the electric wire circuit breaker 1 with trip gear of one embodiment of the invention.
Herein, interrupter 30 is known in the field and will be described in detail.
Shut-down mechanism 10 is suitable for stator 400 to rotate to opening/closing or dropout position.
Shut-down mechanism 100 is included in the action bars 110 rotating between opening/closing or dropout position and the first elastic component 120 that action bars 110 is back to open position.
The rotating shaft of the inner upper end that is coupled to housing 20 described below is set in the lower end of action bars 110.
Upper end at action bars 110 arranges the knob about the rotating shaft of action bars 110 lower ends, and this button can be rotated to opening/closing or dropout position.
That is to say, in the time that action bars 110 is rotated to open position, the removable contact 410 of mover 400 described below contacts with the fixed contact of stator 300.
On the other hand, in the time that action bars 110 is rotated to off-position, the removable contact 410 of mover 400 separates with the fixed contact 310 of stator 300.
The first elastic component 120 is connected to the upper end of action bars 110 at one end thereof place, and is connected to the longitudinal end of the 4th connecting rod 540 described below at its lower end.
Certainly, the first elastic component 120 directly can be connected to an end of mover 400.
Herein, nail 210 is set to rotate in relative direction, and with the multi-joint link component 500 rotating to position latching or off-position is interlocked.
For this reason, action bars 110 can further comprise breech lock 230, and described breech lock 230 is for promoting in a clockwise direction and rotating lock keeper 220, or for keeping and the latch mode of breech lock keeper 220 during breech lock 230 normal runnings.
Action bars 110 can further comprise for applying elastic force and makes nail 210 be back to the 3rd spring (not shown) in home position, and make breech lock keeper 220 be back to the 4th spring (not shown) in home position for applying elastic force.
Herein, the 3rd spring can be the helical spring that applies compression stress.The 4th spring can be the torsionspring that is connected to the rotating shaft of breech lock keeper 220.
That is to say, as shwon in Figures 5 and 6, in the time that in the state that stator 300 and mover 400 fuse each other, action bars 110 rotates to off-position, stator 210 interlocks with the third connecting rod 530 by rotation in a clockwise direction described below.
Then, the breech lock keeper 220 interlocking with action bars 110 rotates in a clockwise direction, to discharge from action bars 110.
Because action bars 11 in this state is released, so the action bars 110 being discharged by the elastic force of the first elastic component 120 is back to open position.
Herein, stator 300 is set to corresponding to relative vertical direction, thereby its vertical direction does not contact.
In the time of the abnormal current producing, mover 400 rotates to stator 300 and opening/closing or dropout position.
For this purpose, the rotating shaft that is formed on an end of the main body 2 of mover 400 is rotatably connected to housing 20 at one end thereof place, thereby and the relative end of rotating shaft optionally form and the Limited Current that contacts of stator 300.
The rear end of fixed contact 310 protrudes to be used as arc runner (not shown).
In the time that mover 400 and stator fuse each other, multi-joint link component 500 interlocks with rotating to the action bars 110 of off-position, to discharge locking component 200.
Herein, link component 500 comprises first connecting rod 510, and first connecting rod 510 is connected to mover 400 at its longitudinal end place, when rotating to off-position when action bars 110 and action bars 110 interlock.
First connecting rod 510 and second connecting rod 520 longitudinal end connected to one another are bent upwards.
Under this state, in the time that stator 300 and mover 400 fuse each other, first connecting rod 510 and second connecting rod 520 are interlocked with one another, laterally stretch to be rotated to the action bars 110 of off-position.
In the time of second connecting rod 520 extending transversely, the longitudinal end transverse rotation of third connecting rod 530, and the end that the other end of third connecting rod 530 can promote locking component 200 is to discharge locking component 200.
Can be provided for applying second elastic component 600 of compression stress to second connecting rod 520 in the lower end of third connecting rod 530.
In the time that action bars 110 rotates to open position, the second elastic component 600 applies for making first connecting rod 510, second connecting rod 520 and third connecting rod 530 be back to the compression stress in their home position.
On the contrary, in the time of stator 300 and mover 400 normal running, because link component 500 rotates together with the rotation of mover 400, so not perturbation operation bar 110 of link component 500.
That is to say to only have in the time that the fixed contact of stator 300 and the removable contact 410 of mover 400 fuse each other, link component 500 just interlocks with action bars 110.
Be provided with the 4th connecting rod 540 in a side of mover 400, the longitudinal end of mover 400 is rotationally attached to the 4th connecting rod 540.
Thereby the first elastic component 120 is connected to respectively the other end and the action bars 110 of the 4th connecting rod 540 and applies tension force at its opposed end place.
When mover 400 and stator 300 fuse each other, the 4th connecting rod 540 rotates the open position of predetermined angle to action bars 110, to change the stagger angle of the first elastic component 120.
As a result, even the fusion each other due to the abnormality of electric wire circuit breaker 1 of the contact between mover 400 and stator 300, the present invention also can keep the open position of action bars 110.
Therefore, even if user also can easily identify the abnormality of contact and also can reduce accident risk in the time of action bars incorrect.
Although above and disclose some embodiment, should be understood that, under the premise without departing from the spirit of the present invention, can make various improvement, modification, be out of shape and be equal to embodiment.Therefore, scope and spirit of the present invention should only limit by claims and the equivalent thereof enclosed.
That is to say, should be understood that, these embodiment that provide only limit the present invention by any way for illustrating and being not used in, and scope of the present invention is only passed through enclosed claims restriction.All fall into scope of the present invention according to all improvement that draw in claims and equivalent thereof, modification and distortion.
