Problems solved by technology
Therefore, when the coil wire is fixed to the pin terminal by soldering, if thermal deformation occurs near the corner of the bobbin due to the heat of soldering, the coil wire may sink to the corner, and there is a possibility that Coil wire tension reduction
Such a decrease in the tension of the coil wire may lead to collapse of the winding of the coil wire wound on the bobbin, and may even cause a short circuit between the coil wire and the laminated core body.

Embodiment Construction
[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0032] figure 1 is a longitudinal sectional view showing the overall structure of the rotating electric machine according to this embodiment, figure 2 is equivalent to figure 1 The cross-sectional view of the II-II section in .
[0033] exist figure 1 and figure 2 Among them, the rotating electric machine 1 is an inner rotor type motor including a stator 2 and a rotor 3 , and the rotor 3 is provided inside the stator 2 . The stator 2 is arranged on the inner peripheral surface of the frame 4 in a manner opposite to the rotor 3 in the radial direction, and has: a laminated iron core body 5; a bobbin 6 through which the laminated iron core body 5 passes; and is wound on the bobbin 6 The coil wire7. In order to electrically insulate laminated core body 5 and coil wire 7 , bobbin 6 is made of an insulating material such as resin. On the axial side of the bobbin 6 (...

PROBLEM TO BE SOLVED: To prevent winding jumble of a coil wire of a bobbin. SOLUTION: A bobbin comprises: an inclined part 25 formed on a terminal surface 21 of a terminal stage part 18, so that a coil wire 7 is arranged from a winding end position P1 at a trunk part 17 to a winding start position P2 at a pin terminal 20 in a linear form. By the presence of the inclined part 25, a place where the coil wire 7 contacts a corner of the terminal surface 21 and is bent is eliminated so that the slump of the coil wire 7 caused by generation of heat deformation of the corner due to soldering heat does not occur when a coil wire terminal 7a is fixed to the pin terminal 20. Accordingly, reduction in tension of the coil wire 7 can be prevented and winding jumble of the coil wire 7 can be prevented. COPYRIGHT: (C)2012,JPO&INPIT
Description
technical field [0001] The present invention relates to a bobbin for winding a coil wire and a rotating electrical machine including the bobbin. Background technique [0002] In order to electrically insulate the coil wire and the laminated core body, a bobbin made of an insulating material such as resin is used. Conventionally, there is known a rotating electrical machine in which a coil wire is wound around a bobbin and used as a stator (for example, refer to Patent Document 1). In this rotating electrical machine, the end of the coil wire is wound around the pin terminal and fixed with solder at the end of winding. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 5-328653 [0004] In the conventional art described above, there is a portion where the coil wire contacts and bends the corner of the bobbin between the winding end position of the coil wire to the bobbin and the winding start position of the pin terminal. Therefore, when the coil wire is...
