Subtract recirculation hole 111 described in multiple to be located on the center line.Subtract recirculation hole 111 to be located on center line i.e. positioned at the connecting plate 11
Middle part, avoid subtracting recirculation hole 111 and be located at side, electricity is exported to support ear 12 by connecting plate 11 to influence external conductor
Stream.
In the present embodiment, two support ears 12 are upwardly extended from the two sides of the connecting plate 11 respectively, then
After being bent to spacing compatible with 31 thickness of the turning end towards direction close to each other, bend straight up.By so curved
Folding increases the heat dissipation area of support ear 12.
Further, the both sides of the connecting plate 11 are equipped with arc notch 112, and the arc notch 112 is adjacent to the branch
Support the setting of 12 bottom of ear.The junction of support ear 12 bottom and connecting plate 11, especially close to the junction of external conductor one end electricity
Current density is big, and is conducive to electric current by two arc notch 112 and is flowed to the one end flowed back far from the circuit, further decreases this time
The electric current on road, to reduce the electrodynamic repulsion force of circuit generation.
There are many elasticity shelfs 40 and the matching relationship of contact body 30, in the present embodiment, the lower part of the turning end 31
Elastic force post 311 is respectively equipped on two side, the Elastic force post 311 is disposed in proximity to the side of the contact end 32；The elastic force
Frame 40 includes that 41, two elastic springs 43 of elastic plate and axis of elasticity 42,41 one end of the elastic plate correspond to the Elastic force post 311
If there are two section plate 411 is drawn, it is described draw assembly protrusion 4111 is respectively equipped on section plate 411；Two elastic springs 43 are distinguished
Setting is in assembly protrusion 4111；41 other end of the elastic plate is set there are two rotate ear 412, the axis of elasticity 42 and institute
Rotate ear 412 is stated to be rotatably assorted.
Wherein, 42 both ends of axis of elasticity and the other component of breaker are fixedly connected, the other end of elastic spring 43 also with
The other component of breaker is fixedly connected.Section plate 411 is drawn in the promotion of elastic spring 43, draws 411 one side of section plate with elastic plate 41
It is rotated around axis of elasticity 42, on the other hand, draws the Elastic force post 311 that section plate 411 pushes contact body 30, to drive moving contact to carry out
Divide-shut brake moves.
During divide-shut brake, moving contact moves breaker along different directions, in order to make the elastic spring 43 not
By the interference of the contact body 30, need to increase 43 plus protective device for elastic spring.
In the present embodiment, the elasticity shelf 40 further includes protection board 413, and the protection board 413 draws section plate 411 by described
End extends towards the bending of 43 direction of the elastic spring.It is tilted to 43 direction of elastic spring using protection board 413, thus will
That two elastic springs 43 cover, and do not allow after its stress and are subjected to displacement.
Preferably, the protection board 413 and draw between the angle of section plate 411 is 125 °~145 °.In this angular range,
