Go out) insulation, and each terminal 50 of stator winding 40 is conductively connected with corresponding connection terminal 30 by welding.It is fixed in welding
, it is necessary to which connection unit 1 is first fixed with stator winding 40 before the terminal 50 of sub- winding 40 and the connection terminal 30 of connection unit 1
Together, grab 70, and the mating holes corresponding to setting on each insulator are wholely set in the lower surface of body 10 for this, so as to
Stator winding is snapped on grab 70.
In addition, Fig. 1 also show insulation board 20, it will be secured between adjacent stator winding 40.
The problem of above-mentioned existing arrangement is first, due to connection unit 1 and the material character of insulator, the He of grab 70
Mating holes is more fragile, and is difficult to positioning alignment because size is smaller；Second, it is necessary to which additional process pastes insulation board
20, easily misplace；3rd, insulation board 20 easily drops between stator winding, so as to play the work for avoiding short circuit
With；4th, the material of insulation board 20 is paper, is easily broken.
Japanese patent application JPH09-182342A discloses a kind of motor stator, and it includes stator core and stator winding,
Stator core is made up of multistage segmentation iron core, and stator winding is respectively wound around on corresponding segmentation iron core.Adjacent stators winding it
Between short circuit prevented by resin by injection, and insert insulation board between adjacent stators winding, pressure during preventing resin by injection
Power causes stator winding to collapse.
Japanese patent application JP2008-043020A also discloses that a kind of motor stator, it include stator core and stator around
Group, insulation board is inserted between adjacent stators winding.
