A rotating turret 1235 is continued to rotate to the direction far from electromagnet mechanism 121.
Fig. 6 is please referred to, flap body 1242 includes the first mounting portion 1246, the second mounting portion 1247 and extension 1248.
First mounting portion 1246 is connect by extension 1248 with the second mounting portion 1247, in the present embodiment, the first mounting portion 1246, the
Two mounting portions 1247 and extension 1248 are integrally formed, to improve bonding strength.Grab 1243 is set on extension 1248,
In order to 1233 clampings that are open.One end of first rotary shaft 1244 pass through the first mounting portion 1246, and with the first mounting portion
1246 rotation connections, the other end passes through the second mounting portion 1247, and is rotatablely connected with the second mounting portion 1247, and turnover body can
It rotates relative to electromagnet mechanism 121.Second elastic component 1241 is connect with extension 1248, and extension 1248 is set to
The one end of one rotary shaft 1244 far from the second rotary shaft 1245.Specifically, the second elastic component 1241 is energy-stored spring, the second elasticity
Part 1241 is in tensional state always, and the second elastic component 1241 is provided to extension 1248 close to 1245 direction of the second rotary shaft
Pulling force.
In the present embodiment, the first rotary shaft 1244 and the second rotary shaft 1245 are located on same perpendicular, the first rotation
Axis 1244 is located at the surface of the second rotary shaft 1245, and extension 1248 is located at the first rotary shaft 1244 far from electromagnet mechanism
The oblique upper of 121 sides, the friendship of the first rotary shaft 1244, the second rotary shaft 1245 and extension 1248 and the second elastic component 1241
Point combination forms triangle, and the second elastic component 1241 provides pulling force obliquely to extension 1248, and pulling force is far from electromagnet
The component very little in the direction of mechanism 121, due to the clamping dynamic balance between the component and grab 1243 and opening 1233, so making
The clamping power obtained between grab 1243 and opening 1233 becomes smaller, so that clamping power will not cause the rotation of rotating member 1232
It influences, avoids since the excessive rotation of obstruction rotating member 1232 of clamping power is to influence the case where open circuit works.
Fig. 7 and Fig. 8 are please referred to, A point is the tie point of the second elastic component 1241 and extension 1248 in figure, and B point is first
The axle center of rotary shaft 1244, C point are the tie point of the second elastic component 1241 and the second rotary shaft 1245.Specifically, when circuit electricity
When stream is less than preset value, grab 1243 and opening 1233 are clamped, at this time work of the flap body 1242 in the second elastic component 1241
With lower by pulling force F1 obliquely, the direction of pulling force F1 is that pulling force F1 is made force analysis, is decomposed into from A from A point to C point
Point arrives the component F2 in the direction (direction abbreviation AB) of B point and the component F3 perpendicular to the direction AB, component F2 do not do work, component
F3 can pull the rotation acting of flap body 1242, at this time component F3 very little, so that between grab 1243 and opening 1233
Clamping power becomes smaller；When circuital current is more than preset value, electromagnet mechanism 121 generates magnetic force and adsorbs to rotating member 1232,
Since clamping power is small, so the magnetic force can overcome clamping power easily, so that grab 1243 and opening 1233 are detached from, rotating member
1232 overcome the elastic force of the first elastic component 1231 to rotate under magneticaction, and flap body 1242 is in the second elastic component
It is rotated under 1241 elastic force effect to the direction far from electromagnet mechanism 121, in the process, the direction of pulling force F1 occurs to turn
Dynamic, component F2 reduces, and component F3 increases, and component F3 is able to drive flap body 1242 to the direction far from electromagnet mechanism 121
Accelerate rotation, so that tripping mechanism 180 be pushed to rotate, so that moving contact 130 is separated with static contact 140, and then realizes circuit
Cutting.
In the present embodiment, the quantity of the second elastic component 1241 is two, and two elastic components are arranged at intervals at extension 1248
And second between rotary shaft 1245, to enhance the pulling force to extension 1248, and makes stress balance, it is not limited to this, the
The quantity of two elastic components 1241 can be one, or three, be not especially limited to the quantity of the second elastic component 1241.
Fig. 9 is please referred to, electromagnet mechanism 121 includes conductor wire snare 1211 and hydraulic component 1212.Conductor wire snare
