Dynamic movable contact connector 620 moves.
Refering to Fig. 3, when kick, i.e., locking part 640 is connected to the connecting hole 621 and fixing piece 630 of movable contact connector 620
Kick hole 632 in when, the distance of the oscillation center O of locking part 640 to drive connection part 610 is equal to or more than drive connection part
610 kick outer wall 612 to the distance of the oscillation center O of drive connection part 610, wherein locking part 640 to oscillation center O away from
With a distance from for locking part 640 away from part nearest oscillation center O to oscillation center O.Due to locking part 640 to oscillation center O
Distance be equal to or more than kick outer wall 612 to the distance of oscillation center O, and drive connection part 610 and movable contact connector 620
It is tensed by elastic component 650, therefore locking part 640 is with the disengaging storage tank 611 of movable contact connector 620 and along the kick of arc
Outer wall 612 moves upwards, and make the movable contact portion 723 being connected with movable contact connector 620 rapidly far from stationary contact portion 300 with
Complete kick.
When kick, fixing piece 630 is rotated counterclockwise in company with locking part 640 along oscillation center O.Suffered by fixing piece 630
When external force disappears, locking part 640 and movable contact connector 620 is driven to be rotated clockwise around oscillation center O, and finally will lock
Firmware 640 is fixed in lock-bit hole 631, and movable contact connector 620 returns in the storage tank 611 of drive connection part 610.
Fixing piece 630 further includes kick trigger arm 633, as shown in Figure 1 to Figure 3, when forcing in kick trigger arm 633, is dashed forward
Jumping trigger arm 633 drives fixing piece 630 is whole to be rotated in an anti-clockwise direction around oscillation center O, and locking part 640 is from fixing piece 630
Lock-bit hole 631 moves to kick hole 632 to move to kick position from lock-bit position, hereafter as described above, kick process occurs.
Second embodiment
Fig. 5 to Fig. 7 show the structural schematic diagram of second embodiment of the invention, and wherein Fig. 7 is the sectional view of Fig. 6, with aobvious
Show the structure and the course of work of fixing piece.Kick component 800 includes drive connection part 810, movable contact connector 820, fixes
Part 830 and locking part 840.The swing of drive connection part 810 is connected on shell comprising storage tank 811.Movable contact connector
820 are connected with movable contact portion 723 comprising connecting hole 821.
The swing of fixing piece 830 is connected on shell, including the first fixing piece 833 and the second fixing piece 834.First fixing piece
833 swings are connected on shell, have latch 833a.Second fixing piece 834 has the latch 833a phases with the first fixing piece 833
Corresponding card slot 834a.One end of first fixing piece 833 and one end of the second fixing piece 834 are rotatablely connected, the first fixing piece 833
It is respectively provided with latch 833a and card slot 834a with the other end of the second fixing piece 834, and locking part 840 is through at the second fixing piece
In the connecting hole 821 of the 834 connecting hole 834b and movable contact connector 820 with the sides card slot 834a.
Before kick, fixing piece 830 is located at lock-bit position, at this point, the latch 833a correspondence of the first fixing piece 833 is connected to the
In the card slot 834a of two fixing pieces 834, locking part 840 is lock onto in the storage tank 811 of drive connection part 810, and then will
Movable contact connector 820 is lock onto in the storage tank 811 of drive connection part 810.Drive connection part 810 drives movable contact when moving
Connector 820 moves, to which the movable contact portion 723 that driving is connected with movable contact connector 820 moves.
When kick, fixing piece 830 is located at kick position, and 833 stress of the first fixing piece is swung, the card of the first fixing piece 833
Tooth 833a is detached from the card slot 834a of the second fixing piece 834, and 840 pressing contact of locking part is detached from the storage tank of drive connection part 810
811, and then movable contact connector 820 is detached from from the storage tank 811 of drive connection part 810.
Drive connection part 810 further includes kick outer wall 812, and kick outer wall 812 connects storage tank 811.Kick outer wall 812 is in
Arc, and it is concentric with the oscillation center O of drive connection part 810.
In addition, the oscillation center O of drive connection part 810 is the oscillation center of the first fixing piece 833, i.e. drive connection part
810 and first fixing piece 833 suit on the same axis, the axle center of the axis is drive connection part 810 and the first fixing piece 833
Oscillation center O.One end of second fixing piece 834 is also rotatably socketed on the axis, unlike, the second fixing piece 834 is logical
A slot hole is crossed to be socketed on the axis.
It is tensed and is connected by an elastic component 850 between movable contact connector 820 and drive connection part 810.I.e. movable contact connects
One end of fitting 820 connects elastic component 850, and the other end connects movable contact portion 723, while connecting hole 821 is located at connection elastic component
850 one end.
The course of work of the present embodiment is：Before kick, the latch 833a of the first fixing piece 833 is stuck in the second fixing piece 834
Card slot 834a in, to locking part 840 is fixed in the storage tank 811 of drive connection part 810 when, locking part 840 to drive
The distance of the oscillation center O of follower link 810 is less than the kick outer wall 812 of drive connection part 810 to the pendulum of drive connection part 810
The distance of dynamic center O, the wherein distance of locking part 840 to oscillation center O are the part nearest away from oscillation center O of locking part 840
To the distance of oscillation center O.Since the distance of locking part 840 to oscillation center O is less than kick outer wall 812 to oscillation center O's
Distance, and stopped by kick outer wall 812 by locking part 840 between drive connection part 810 and movable contact connector 820 and will move
Contact connector 820 is fixed in storage tank 811.It will by the first fixing piece 833, the second fixing piece 834 and locking part 840
Drive connection part 810 and the relative position of movable contact connector 820 are fixed, and the movement of drive connection part 810 drives movable contact connection
Part 820 moves.
When kick, the latch 833a of the first fixing piece 833 is detached from the card slot 834a of the second fixing piece 834, locking part 840 to
The distance of the oscillation center O of drive connection part 810 is equal to or more than the kick outer wall 812 of drive connection part 810 to drive connection
The distance of the oscillation center O of part 810, wherein locking part 840 to oscillation center O distance be locking part 840 away from oscillation center O most
Close part to oscillation center O distance.Since the distance of locking part 840 to oscillation center O is equal to or more than kick outer wall 812
