Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode the present invention will be described in detail：
As shown in Figure 1,1 can be equipped with draw bar 2 in pedestal, draw bar 2 be set in shaft 4, and draw bar 2 is equipped with pusher dog 18,
Microswitch 43 is also fixed on pedestal 1, microswitch 43 is set to 18 lower section of pusher dog, and draw bar 2 is equipped with driving piece 8.Base
It is set in seat 1 there are two spring coupling part 29, sets that there are two spring connecting pole 21, each pair of spring coupling part 29 and bullets on draw bar 2
Spring 3 is connected between spring connecting pole 21.
As shown in Fig. 2, draw bar 2 is equipped with pusher dog 18 and three driving pieces 8, draw bar 2 passes through draw bar rotation sky 19
It is set in shaft 4.
As shown in figure 3, pedestal 1 is equipped with base location hole 16, shaft 4 is set in base location hole 16.Pedestal 1 is equipped with
Two spring coupling parts 29.
As shown in figure 4,5 top of support element is equipped with threaded hole 11,5 bottom of support element is equipped with kidney ellipsoid interconnecting piece 24, oval
It is equipped with cylindrical transition portion 23 between 5 main body of 24 top of shape interconnecting piece and support element, sets that there are two limits on 5 body floor of support element
Position boss 15.
As shown in figure 5, being equipped with round connecting cavity 39 in holder 42,39 top both sides of connecting cavity are equipped with edge sealing 40, edge sealing 40
It is equipped with positioning groove, positioning groove coordinates with the positive stop lug boss 15 on support element 5.The kidney ellipsoid interconnecting piece 24 of support element 5 is set
In connecting cavity 39, the cylindrical transition portion 23 of support element 5 is located at the centre of the edge sealing 40 of both sides.Pedestal 1 is equipped with lock chamber 25,
5 top of support element is set in the lock chamber 25 of pedestal 1, and 25 top of lock chamber is equipped with circular hole, passes through between support element 5 and pedestal 1
Screw is attached.
As shown in fig. 6, set on holder 42 there are three thermal element 41, three thermal elements 41 respectively with three bimetallic elements 26
Connection, the end corresponding with driving piece 8 of bimetallic element 26 are equipped with adjustable actuator 36, and bimetallic element 26 is not heated
When, actuator 36 is detached with driving piece 8.
In conjunction with Fig. 5 and Fig. 6, the kidney ellipsoid interconnecting piece 24 of support element 5 is after the intermediate insertion circle connecting cavity 39 of edge sealing 40
It rotates a certain angle, the positioning groove on edge sealing is positioned with the clamping of positive stop lug boss 15 on support element 5, and support element 5 is installed
It on holder 42, then will be attached between pedestal 1 and support element 5, that is, complete the installation of pedestal 1 and holder 42.
It specifically combines shown in Fig. 6, when breaker normal operation, since the active force of spring 3 makes draw bar 2 be located at freely
Position, pusher dog 18 is in not contact condition with microswitch 43, while actuator 36 is also at not contact condition with driving piece 8,
At this point, the output signal of microswitch 43 is normally opened signal.
In the case of breaker is in sustained overload, i.e., when actual current is more than rated current in circuit, breaker thermal member
41 persistent fever of part makes to be bent to draw bar 2 after bimetallic element 26 is heated, and the actuator 36 of 26 end of bimetallic element drives
Driving piece 8 on draw bar 2 makes draw bar 2 overcome active force 4 rotation around the shaft of spring 3, when draw bar 2 rotates certain angle
When spending, pusher dog 18 touches microswitch 43, at this point, the output signal of microswitch C is normally closed signal.
After fault clearance, bimetallic element 26 automatically resets, and so that 8 stress of driving piece of draw bar 2 is eliminated, in spring
Under 3 active force, draw bar 2 is made to be restored to initial position, same pusher dog 18 also returns to initial position, at this point, pusher dog 18
With microswitch 43 in contact condition, the output signal of microswitch C do not switch to normally opened signal by normally closed signal.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made in any form
Limitation, it is every according to the technical essence of the invention to any simple modification, equivalent change and modification made by above example,
In the range of still falling within technical solution of the present invention.
