Please refer to Fig. 1-4, wherein Fig. 1 is the structural representation of circuit breaker closing conjunction state provided by the embodiment of the utility model
Figure；Fig. 2 is the structural schematic diagram of part-structure in breaker shown in Fig. 1；Fig. 3 is the exploded view of part-structure shown in Fig. 2, Fig. 4
It is the structural schematic diagram of breaker off-state provided by the embodiment of the utility model.Breaker includes insulation shell 1 and sets
In in the insulation shell 1 static contact 3, moving contact 4, electromagnetic unlocking device 5 and breaker operating mechanism 7.
The operating mechanism 7 of the breaker is moved including handle 71, the drive rod 72 being connected on the handle 71, with described
The lever 73 of the connection of contact 4, lock 75, the connection lever 73 for being coaxially disposed with the lever 73 and being connect by shaft 74
With the reset spring 76 of the lock 75.The lever 73 is equipped with sliding slot 731, and the lock 75 is equipped with catching groove 751, in institute
When stating reset spring 76 and being in original state, the sliding slot 731 constitutes a lock groove 7A, the drive rod with the catching groove 751
72 one end far from the handle 71 are locked in the lock groove 7A, and the directed force F of the drive rod 72 is by the locking
The constraint of slot 7A is divided into the first component F1 acted on the lever 73 and acts on the second component F2 on the lock 75,
After the catching groove 751 of the lock 75 and the drive rod 72 are threaded off, the reset spring 76 generates elastic deformation, in institute
It states under the effect of 76 elastic force of reset spring, the moving contact 4 is rotated with the lever 73 to realize the static contact 3 and the dynamic touching
First 4 separated movement, and the relatively described sliding slot 731 of the drive rod 72 slides.
Wherein, the insulation shell 1 is equipped with the opening 11 as 71 channel of handle, and the handle 71 is configured to
Limitedly be pivoted on the static contact 3 on the insulation shell 1 and the moving contact 4 be in closed state closed position and
Corresponding between the separated open position of the static contact 3 and the moving contact 4, and the handle 71 and the drive rod 72 connect
Connect to form toggle mechanism, the fixed pin B decentraction of the joint A of the toggle mechanism and the handle 71, the shaft 74 with it is described
Insulation shell 1 is fixed, and (for example, fixation hole (not shown) can be arranged in the insulation shell 1, it is solid that the shaft 74 is fixed on this
Determine in hole), the static contact 3 is fixed in the main body of the electromagnetic unlocking device 5.
As shown in Figure 1, when breaker is in normal condition (breaker there is no serious overload or short circuit and
When the failures such as under-voltage), since the drive rod 72 is locked in the lock groove 7A far from one end of the handle 71, so as to
To make the drive rod 72 that the lever 73, the lock 75 and the moving contact 4 be driven to revolve by stirring the handle 71
Turn to realize 4 closing or opening of the static contact 3 and the moving contact.
When serious overload or short circuit and the failures such as under-voltage occur for breaker, the electromagnetic unlocking device 5 is powered.It is logical
After electricity, the ram of the electromagnetic unlocking device 5 hit it is described lock 75 make it is described lock 75 the catching groove 751 with it is described
