In addition, the gap between two adjacent coils 112 before the combination of the segmented iron core 111 and the circle is larger, so that the insertion of the interphase insulating paper 113 is more convenient.
In an embodiment of the present application, referring to fig. 3, each of the two first folding edges 1132 is provided with an abutting portion 1134, so that when the inter-phase insulation paper 113 is installed, the two abutting portions 1134 elastically abut against the two adjacent packages 112 respectively, so as to eliminate a gap distance between the two adjacent packages 112, and achieve positioning of the inter-phase insulation paper 113 between the two adjacent packages 112; in addition, due to the arrangement of the two abutting portions 1134, the interphase insulating paper 113 is uniformly stressed between the two adjacent coils 112, so that the phenomenon of toppling over on one side is avoided, and the yield of the installation of the interphase insulating paper 113 is further improved. It is understood that, in other embodiments of the present application, when the gap between two adjacent packages 112 before the circle is closed is small, and the structural strength of the interphase insulating paper 113 is large, the abutting portion 1134 may be provided on only one of the first folding edges 1132, and the other first folding edge 1132 abuts against the corresponding package 112, which is not limited herein.

It is understood that, in other embodiments of the present application, the abutting portion 1134 may be disposed near an end of the first folding edge 1132 facing away from the first folding mark 1133, which also can improve the positioning reliability of the inter-phase insulation paper 113 between two adjacent packages 112.
In an embodiment of the present application, the inter-phase insulating paper 113 is formed by bending a piece of insulating paper, wherein the abutting portion 1134 is formed by bending a portion of the insulating paper connected to the first folding 1132, for example, the portion may be bent one or more times, that is, the abutting portion 1134 and the first folding 1132 are an integral structure, and the abutting portion may be formed by bending a piece of insulating paper along each folding line in sequence. It should be understood that, in other embodiments of the present application, the abutting portion 1134 may also be mounted on the first folding edge 1132 in a pasting manner, for example, one inter-phase insulating paper 113 is formed by pasting three kinds of insulating papers together, and other elastic structures may also be pasted on the first folding edge 1132, which is not limited herein.
In an embodiment of the present application, the thickness range of the inter-phase insulating paper 113 is 0.15mm to 0.35mm, for example, the thickness range may be 0.15mm, 0.2mm, 0.25mm, 0.3mm, or 0.35mm, and the thickness of the inter-phase insulating paper 113 is limited, so that the abutting portion 1134 and the inter-phase insulating paper 113 have high strength and elasticity, the abutting portion 1134 has a sufficient abutting force with the coil 112, and the inter-phase insulating paper 113 can abut and be positioned between two adjacent coils 112.
In an embodiment of the present application, referring to fig. 3, a portion of the insulating paper connected to the first folding edge 1132 is bent once to form an abutting portion 1134, the abutting portion 1134 is connected to the first folding edge 1132 in a V shape, specifically, the abutting portion 1134 and the first folding edge 1132 are bent in a V shape along a section perpendicular to the first folding edge 1133, that is, the abutting portion 1134 is bent reversely relative to the first folding edge 1132, and when the abutting portions 1134 are disposed on the two first folding edges 1132, the whole inter-phase insulating paper 113 is in a "W" shape. In this embodiment, the abutting portion 1134 and the first folding edge 1132 are connected in a V shape, so that the width between the abutting portion 1134 and the first folding edge 1132 is increased, the width of the whole interphase insulating paper 113 is further increased, the gap distance between two adjacent packages 112 is favorably eliminated, and the interphase insulating paper 113 is conveniently inserted between two adjacent packages 112 and is abutted and positioned. As can be seen from fig. 3, the gap between two adjacent coils 112 is also substantially V-shaped, so that when the abutting portion 1134 is connected to the first fold 1132 in a V-shape, the inclination direction of the abutting portion 1134 is similar to the inclination direction of the coil 112 toward the abutting portion 1134, which is favorable for the adhesion between the abutting portion 1134 and the coil 112. It is understood that, in other embodiments of the present application, the abutting portion 1134 may be reversely folded for a plurality of times, so as to increase the structural strength and the abutting elasticity of the abutting portion 1134, which is not particularly limited herein.
