The first buckle sheet is fixed in the wire passing groove and is arranged corresponding to the partial width of the wire passing groove, and the rest part of the wire passing groove except the first buckle sheet is used as a wire passing hole;
The second cramp, it is equipped with a plurality of, the second cramp is fixed in the remaining cramp inslot except that the wire casing with the mode of one-to-one and corresponds the whole width setting in cramp groove.
Optionally, the first buckle piece is arranged corresponding to half of the width of the wire passing groove, and the part of the wire passing groove corresponding to the other half of the width is used as the wire passing hole.
Optionally, the first button plate and the second button plate are welded in the button plate groove.
Optionally, a marking groove is formed at the bottom of the wire through hole.
Compared with the prior art, the technical scheme provided by the utility model has the following advantages:
the stator core of the explosion-proof motor provided by the utility model adopts one of the buckle piece grooves as the wire passing groove, one part of the wire passing groove is used for wire passing, the other part of the wire passing groove is still connected with the buckle piece, and the wire passing groove is used as the buckle piece groove and also has the function of a wire passing hole. Therefore, no wire through holes are required to be additionally formed in the stator punching sheet, and the used die can be suitable for other stator punching sheets without the wire through holes, so that the increase of the punching sheet cost is avoided; meanwhile, spot facing is not needed after lamination of the stator core is completed, so that redundant process and influence on machining efficiency are avoided.
