Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
Referring to Fig.1,2, the present embodiment includes upper contact tube 1 and static contact 7, and static contact 7 is set to upper 1 top of contact tube, on
It is equipped with dynamic fingertip 4 in contact tube 1, bus switching current device is equipped in upper contact tube 1, bus switching current device includes conduction
Band 2, lining 3, auxiliary moving contact 5, auxiliary static contact 6, reset spring 8, bracket 9 and sliding bar 10, conductive strips 2, are answered at lining 3
Position spring 8, bracket 9 and sliding bar 10 are set in upper contact tube 1, and 2 one end of conductive strips is connect with upper 1 inner wall of contact tube, the other end
It is connect with sliding bar 10, reset spring 8 is set to the lower section of lining 3 and is set on sliding bar 10, and bracket 9 is fixed on sliding bar 10
On, and one end is fixed on 8 upper end of reset spring, the other end is fixed on 8 lower end of reset spring, is fixed on conduction in the middle part of bracket 9
On 1 inner wall of pipe, dynamic fingertip 4 is set to upper 1 internal upper part of contact tube and connect with lining 3, and the top of sliding bar 10 is equipped with insulated column 11,
Insulated column 11 is set on sliding bar 10, and auxiliary moving contact 5 is set to the top of upper contact tube 1, and auxiliary static contact 6 is set to static contact 7
Bottom end；Assisting 5 top of moving contact is the cambered surface being recessed inwardly, and auxiliary moving contact 5 is set in insulated column 11 by sliding bar 10；
Auxiliary connecting rod 12 is equipped in static contact 7, static contact 7 is stretched out in 12 lower end of auxiliary connecting rod, and auxiliary static contact 6 is set under auxiliary connecting rod 12
End, the bottom end of auxiliary static contact 6 are outwardly projecting cambered surface, assist the protrusion cambered surface of static contact 6 and the recess of auxiliary moving contact 5
Cambered surface is coincide.
When disconnecting switch is closed a floodgate, upper contact tube 1 moves upwards under the action of actuating force, assists moving contact 5 with upper conduction
Pipe 5 is moved to auxiliary 6 direction of static contact together, arc burning is generated before auxiliary moving contact 5, auxiliary static contact 6 contact, auxiliary
During power-assist contact 5 moves upwards, auxiliary moving contact 5 is contacted and is withstood with auxiliary static contact 6, go up at this time contact tube 1 after
Continuous to move upwards, auxiliary moving contact 5 is moved downward with auxiliary static contact 6 relative to upper contact tube 1, the reset in upper contact tube 1
