Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an interphase insulating paper of a rotary electric machine used to insulate coils of different phases at a coil end portion of a stator. 2. Description of the Related Art In general, a stator (stator) in a rotating electric machine such as an AC generator for a vehicle generally has a stator core (stator core) having a plurality of slots, and coils at both axial ends of the stator core. And a polyphase coil mounted in the slot while forming an end portion. In a coil having such a multi-phase coil, interphase insulation is provided between coils of different phases at a coil end portion. As an interphase insulating paper for performing such interphase insulation, as shown in FIG. 6, a pair of interphase portions 80 arranged between coils of different phases at respective coil end portions,
81 and a pair of connecting portions 90 and 91 that are integrally connected to each other and are inserted and disposed in a slot, are known (see Japanese Patent Application Laid-Open No. 58-12549, etc.). ). In this interphase insulating paper, the interphase portions 80, 8
The distance between them is substantially equal to the axial length of the stator core. Here, the inter-phase portions 80 and 81 are connected to the connection portion 9.
The reason why they are integrally connected by 0 and 91 is that when the interphase insulating paper is mounted on the stator, the ease of handling of the interphase insulating paper is improved and the interphase insulating paper is reliably held between the coils of different phases. As described above, the inter-phase portions 80 and 81 and the connecting portion 9
The interphase insulating paper in which 0 and 91 are integrated is generally formed integrally by cutting and removing unnecessary portions of an insulating material (eg, a polyester film) in a sheet shape or the like. For example, both ends of the substantially rectangular sheet-shaped insulating material are left as a pair of interphase portions 80 and 81, and the two interphase portions 8 are formed.
The pair of inter-phase portions 80, 81 and the pair of inter-phase portions 80, 81 are cut and removed by cutting out unnecessary portions while leaving a pair of connection portions 90, 91 between the two inter-phase portions 80, 81. Part 8
A pair of connecting portions 90 and 91 for integrally connecting 0 and 81 are integrally formed. Further, as disclosed in Japanese Patent Application Laid-Open No. 58-186346, there is an interphase insulating paper in which both interphase portions formed separately are connected by a thread. [0007] The interphase insulating paper of the rotating electric machine is extremely expensive because it is necessary to use an insulating material having a heat resistance of about 200 ° C or more. For this reason, if the cost required for the interphase insulating paper can be suppressed, it will be possible to greatly contribute to the cost reduction of the rotating electric machine. However, when the interphase insulating paper is formed by cutting and removing the unnecessary portion by hollowing out the space between the phases as described above, the insulating material of the hollowed portion is wasted. For this reason, the material yield of the high-priced insulating material is deteriorated, and the cost of the interphase insulating paper is increased. On the other hand, according to the interphase insulating paper in which the interphase portions formed separately are connected by a thread, unnecessary portions that are wasted can be reduced. However, in this case, a step for fixing the yarn to the interphase part is separately required, and the productivity is reduced due to an increase in the number of steps. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has an object to provide an interphase insulating paper capable of improving the material yield of the insulating material and reducing the cost without lowering the productivity. It should be a technical task to be done. An interphase insulating paper of a rotating electric machine according to the present invention for solving the above-mentioned problems has a pair of interphase portions and a connecting portion for integrally connecting the interphase portions. Each of the inter-phase portions is mounted on a stator of a rotating electrical machine having a stator core having slots and polyphase coils mounted in the slots while forming coil end portions on both ends of the stator core. An interphase insulating paper disposed between the coils of different phases at the respective coil end portions and the connecting portion disposed in a state of extending straight in the slot, wherein the axial length of the stator core is The inter-phase portions facing each other at a distance shorter than the above, and the connecting portion that has at least a portion of the non-straight portion and integrally connects the inter-phase portions are unnecessary portions of an elastically deformable insulating material. Cutting and removing It is characterized by being formed more integrally. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The interphase insulating paper of a rotating electric machine according to the present invention comprises a stator core having a plurality of slots, and a plurality of slots mounted on the slots while forming coil end portions on both ends of the stator core. And a pair of inter-phase portions disposed between the coils of different phases at each of the coil end portions while being mounted on the stator. And a connecting portion which is disposed in the slot so as to extend straight and connects the two interphase portions integrally. The interphase insulating paper according to the present invention is characterized in that the interphase portions opposing each other at a distance shorter than the axial length of the stator core and the non-straight portion at least partially have the two interphase portions integrated. The greatest feature is that the above-mentioned connecting portion to be connected to is integrally formed by cutting and removing an unnecessary portion of an elastically deformable insulating material. As described above, the interphase insulating paper of the present invention is obtained by cutting and removing unnecessary portions of an elastically deformable insulating material.
The inter-phase portions facing each other at a distance shorter than the axial length of the stator core and a connecting portion having at least a part of the non-linear portion and integrally connecting the two phase portions are integrally formed. For this reason, the area of the unnecessary portion which is cut and removed and wasted becomes smaller as the distance between the two phases becomes shorter.
Therefore, the material yield of the insulating material can be improved, and the cost of the interphase insulating paper can be reduced. Further, the interphase insulating paper of the present invention can simultaneously form both interphase portions and a connecting portion for integrally connecting them by hollowing out a sheet-like insulating material into a predetermined shape. For example, it is not necessary to fix a yarn for connecting the inter-phase portions later, and the productivity is good. When the interphase insulating paper of the present invention is mounted on the stator of the rotating electric machine, the non-linear portion of the connecting portion is inserted and disposed in the slot of the stator core in a state where the non-linear portion is stretched straight by elastic deformation. The inter-phase portions are disposed between coils of different phases at the respective coil end portions. As the insulating material constituting the interphase insulating paper, any material can be used as long as it exhibits the required electric insulation and can be elastically deformed to such an extent that the non-straight portion of the connecting portion extends straight. Not limited. For example, silicon resin, nylon (66 nylon or the like) or polyimide can be used. The shape of the connecting portion is not particularly limited as long as it has a non-straight portion such as a curved portion or a bent portion in at least a part thereof. Here, the connecting portion before connecting to the stator of the rotating electric machine (the connecting portion in which the non-straight portion such as the curved portion or the bent portion has the same curved or bent shape. Hereinafter, the connecting portion before mounting. ) (The distance between both ends of the connecting portion before mounting: d), that is, the connecting portion (in a state after the non-straight portion is straightened to be mounted on the stator). In the following, the ratio (d / D) of the distance (d) between both ends of the connecting portion before mounting to the distance (D, d <D) connecting the both ends of the connecting portion after extension is reduced. The area of the unnecessary portion that is removed by being hollowed out between the portions can be reduced, and the material yield of the insulating material can be further improved. The distance (D) between both ends of the connecting portion after extension is substantially equal to the axial length of the stator core and is constant. Therefore, the value of (d / D) is 以下 or less, 以下 or less, 1 / or less,..., When the non-straight portion is stretched straight by elastic deformation. It is preferable to make the size as small as possible within a range that can prevent the occurrence of. In the case where a curved portion (which is constituted by an arc) is adopted as the non-straight portion of the connecting portion,
It is preferable to increase the curvature because the value of (d / D) can be reduced. On the other hand, when a bent portion is employed as the non-straight portion of the connection portion, it is preferable to reduce the bending angle because the value of (d / D) can be reduced. Further, when the non-straight portion is stretched straight due to elastic deformation, from the viewpoint of preventing the occurrence of cracks and the like, the connecting portion has corners where cracks and the like are likely to occur due to stress concentration at the time of elastic deformation. It is preferable to have a shape that does not have. For example,
When the non-straight portion is a bent portion, the bending point (bending tip) of the bent portion is rounded, or a part of the connecting portion is formed as a curved portion or a bent portion, and the other portion is formed as a straight portion. In this case, it is preferable that the boundary between the straight portion and the curved portion or the bent portion is rounded so that the straight portion and the bent portion or the curved portion are connected by a curved line. The non-straight portion of the connecting portion is as thin as possible (has a narrow width) within a range in which a necessary minimum strength can be secured so as to prevent the occurrence of cracks or the like when extending straight. )
It is particularly preferable to have a local narrow portion in a portion where the amount of deformation is large. The number of the connecting portions is not particularly limited, and may be one or two or more. The strength of the connecting portions is ensured, and the mounting workability when mounting the interphase insulating paper to the stator is improved. From the viewpoint of, it is preferable to use two (or three). The interphase insulating paper of the present invention is formed integrally by cutting and removing unnecessary portions of a sheet-like or film-like insulating material into a predetermined shape. For example, while leaving both ends of the substantially rectangular sheet-shaped insulating material as a pair of interphase portions, leaving a pair of connection portions between the two interphase portions, removing unnecessary portions such as hollowing out between the two interphase portions. Is cut and removed into a predetermined shape, whereby an interphase insulating paper including a pair of interphase portions and a pair of connecting portions that integrally connect both interphase portions can be integrally formed. Although there is no particular limitation on the method of cutting and removing unnecessary portions from an insulating material such as a sheet, it is preferable to use laser cutting that can cut with high accuracy even in a complicated shape.
