Therefore, the wire clamping hole is used for limiting the two enameled wires in the vertical direction, and the enameled wires can be prevented from loosening.

Preferably, the inner side of the boss is provided with a wire inlet groove communicated with the wire clamping hole.

Preferably, the wire inlet groove is trumpet-shaped from bottom to top. Therefore, the enameled wire enters the wire clamping hole from the wire inlet groove, so that the enameled wire is convenient to mount and plays a role in positioning and fixing the enameled wire.

Preferably, the wire clamping hole and the buckle are arranged in a staggered mode.

Furthermore, the fixed foot and the stator framework are of an integrated structure. Therefore, the fixing pins can be formed together when the stator framework is formed, and the production process of the stator framework is simplified.

Furthermore, the fixed foot and the stator framework are of a split structure. Therefore, the height and the position of the fixing foot can be adjusted according to actual conditions.

To sum up, the utility model discloses realize following beneficial effect:

1. the utility model has good reliability and consistency, and can realize automatic welding operation;

2. the utility model discloses the technology is retrencied, and the material is still less, and material and processing cost advantage are obvious.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to the motor winding and the stator frame in fig. 1, the motor winding 10 is installed in the stator frame 20, a plurality of fixing pins 30 extend from one end of the stator frame corresponding to the control board, two buckles 31 for respectively hanging two enameled wires in the wire ends of the enameled wires are arranged on the inner side of the fixing pins, and a clamping groove in the buckle is arranged on the outer side. Two buckles are located between two enameled wires, and two enameled wires are walked around the buckle from the bottom to the top and then are wriggled from outside to inside to converge. The clamping groove in the buckle can also be arranged on the inner side, but the clamping stability of the buckle with the structure is relatively poor. A boss 32 located above the buckle is arranged on the inner side of the fixing foot, a wire clamping hole 321 which penetrates through the boss from top to bottom is formed in the boss, two enameled wires in a group of enameled wire ends penetrate out of the wire clamping hole upwards, and the wire clamping hole is used for limiting the two enameled wires in the vertical direction. Referring to fig. 2, during welding, the enameled wire end passes through the insertion hole of the control plate 40, and after the control plate is loosened, the top of the fixing pin 30 automatically supports the control plate, so that the enameled wire end and the control plate can be automatically welded without being held by hands.

The buckle quantity on the fixed foot also can be one, and two enameled wires share a buckle, also can respectively be provided with a draw-in groove in the left and right sides of this buckle, if alright with separately two enameled wires.

Referring to fig. 3, a wire inlet slot 322 communicated with the wire clamping hole is formed on the inner side of the boss. The width of the wire inlet groove is slightly larger than the diameter of one enameled wire, and the two enameled wires enter the wire clamping holes successively. The enameled wire enters the wire clamping hole from the wire inlet groove, so that the enameled wire is convenient to mount and plays a role in positioning and fixing the enameled wire. The wire inlet groove 322 is trumpet-shaped from bottom to top, so that the enameled wire can conveniently enter the wire clamping hole.

The wire clamping holes in the bosses are arranged in a staggered mode with the buckles, so that the upper clamping points and the lower clamping points of the two enameled wires are staggered by an angle, and the enameled wires can be prevented from loosening.

The fixed foot and the stator framework are of an integrated structure and can also be of a split structure. If the stator framework is of an integrated structure, the fixing legs are formed together when the stator framework is formed, so that the production process of the stator framework is simplified; if the structure is a split structure, the height and the position of the fixing foot can be adjusted according to the actual situation.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention.
