Detailed Description
The invention will be further explained with reference to fig. 1 to 2, in which the broken lines represent folding lines and the solid lines represent boundary lines.
The utility model relates to an insulating part for stator, it includes the body, and the body is the polyester film component, and the shape of insulating part can be tailor and obtain. The body comprises a first insulating part 11 and a second insulating part 12, the first insulating part 11 and the second insulating part 12 are connected through two connecting parts 13, the two connecting parts 13 are arranged in parallel, and the two connecting parts 13 divide the area between the first insulating part 11 and the second insulating part 12 into three separated areas.
When the stator is wound, the main wire and the secondary wire (also called transition wire) need to be separated, and the main wire and the secondary wire exposed at two ends of the stator can be separated through the insulating piece. Two insulators are matched with one stator, the connecting part 13 is arranged in a tooth slot formed between adjacent teeth in the stator, the first insulating parts 11 of the two insulators are positioned on the same end face of the stator, and the second insulating parts 12 are positioned on the other cross section of the stator. The first insulating portions 11 are bent along the length direction thereof, so that the two first insulating portions 11 form a ring shape, i.e., an inner ring and an outer ring for separating the main line and the secondary line. The second insulating portion 12 is also bent in the same manner.
One side edge of the first insulating portion 11 for connecting with the connecting portion 13 is regarded as an inner edge, one side edge of the second insulating portion 12 for connecting with the connecting portion 13 is regarded as an inner edge, one side edge of the first insulating portion 11 opposite to the inner edge is regarded as an outer edge, and one side edge of the second insulating portion 12 opposite to the inner edge is regarded as an outer edge. The two ends of the inner edge are provided with sidelines inclined towards the direction of the outer edge, and the end part of the outer edge and the end part of the inner edge are in arc transition. The middle of the outer edge is formed with a concave V-shaped edge line to facilitate bending of the first and second insulating portions 11 and 12.
The first insulating portion 11 is arranged with a third insulating portion between the first and second insulating portions 11, 12 in the intermediate spacing areas, which can be folded up along its boundary line with the first insulating portion 11.
Since the outgoing line assembly after winding in the stator has three leads, but the winding has two main lines and two sub lines, the leads are connected with one main line and one sub line at the same time, and the leads are connected with one main line and one sub line at the same time, the main line and the sub line at the connection position of the leads cannot be completely separated only by the first insulating part 11 and the second insulating part 12 when the main lines and the sub lines need to be led out after the winding is completed. An insulating layer is formed by folding the third insulating part to separate the main line and the sub line at the lead wire connection position.
The third insulating portion includes a first folded portion 14 and two second folded portions 15, the two second folded portions 15 are arranged in parallel, the first folded portion 14 is located between the two second folded portions 15 and the first insulating portion 11, an intersection point of the first folded portion 14 and the two second folded portions 15 is formed as a circular hole, and a sum of widths of the two second folded portions 15 after being arranged in parallel is equal to a width of the first folded portion 14. The third insulating portion is folded twice to form a trough structure with the first folded portion 14 as a bottom and the second folded portion 15 and the first insulating portion 11 as walls, and the trough structure is used for placing a main line or a secondary line at a lead connection position.
The first insulating portion 11 is further arranged with a fourth insulating portion, which is located between the first insulating portion 11 and the second insulating portion 12 and which is located in one of the other two spaced areas, which can be folded up along its boundary line with the first insulating portion 11. The fourth insulation portion comprises a third folded portion 16 and a fourth folded portion 17, the third folded portion 16 being located between the fourth folded portion 17 and the first insulation portion 11. The fourth insulating part is folded twice to form a groove structure with the third folded part 16 as a bottom, the fourth folded part 17 and the first insulating part 11 as walls, and the groove structure is used for placing a main wire or a secondary wire at a lead connecting part.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
