Connector, and the connector is arranged on the pivot of switch shaft.
Herein advantageously, can more easily be oriented according to the pole case of the present invention, and adjacent pole case is mutual
Gap can reduce.Rotor bearing position is ensured with high degree of alignment and forms the synchronization of switch shaft simultaneously.Avoid tight
Gather the axial direction offsetting of switch shaft in the structure of formula breaker.It may thereby be ensured that the excessive stresses of part and its coupling elements.It is logical
Crossing accurate supporting reduces displacement and torque loss or friction loss.
In one kind extension design, connector is the first component of socket connection.
In another kind extension design, the first connector and the second connector are arranged in switch shaft on the outside of pole case
On mutually opposing end.First connector and the second connector can be designed to different.
In one kind extension design, the first component of grafting is arranged on the first end of switch shaft, and the of grafting
Two parts are arranged on the second end of switch shaft.
In one kind extension design, the first connector is socket, and the second connector is bearing pin, or the first connector
It is bearing pin, and the second connector is socket.
In one kind extension design, stud connector design is axisymmetric into the pivot on switch shaft.
In another kind extension design, pole case includes the first pole shell and the second pole shell, wherein, the first pole shell includes grafting
First component, and the second pole shell includes the second component of grafting.
At least one the first pole case according to the present invention and second according to the present invention are included according to the electric switch of the present invention
Pole case, wherein, the first pole case and the second pole case by its corresponding connector on the common pivot of switch shaft mutually
Connection.
