【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this example In this case, the magnet wire of an AC motor, which is an example of a conductive wire, is connected to a printed circuit board. An example of wiring without contact with printed wiring will be given. First, the configuration is shown in Figure 1 (cross-sectional view of the AC motor) and Figure 2 (perspective view of the board). I will explain about it. The AC motor 10 includes a stator 14 fixed within a bracket 12 and a bracket. A rotor 16 rotatably disposed within the bracket 12 and a rotor 16 fixed within the bracket 12. The substrate portion 18 includes a The stator 14 includes a plurality of coils 22 formed by winding electric wire around a core 20 in the circumferential direction. They are arranged side by side. The rotor 16 rotates on a ball bearing 24 fixed within the bracket 12. A rotating shaft 26 is supported and rotatably arranged within the stator 14 . The board section 18 includes a board holder 28 fixed to the bracket 12 and a board holder 2 8, and a printed circuit board with printed wiring (pattern) 30 printed on the top surface. It consists of 32. The printed circuit board 32 is fitted into the board holder 28. Also, A lead wire 34 (not shown in FIG. 1) is connected to the printed wiring 30 on the top surface of the printed circuit board 32. ), or a magnet wire, which is an example of a conductive wire drawn out from the coil 22. The tip of 36 is soldered and fixed to round 38.

[0007] Next, the substrate section 18 will be explained. Of the printed circuit board 32, select a predetermined portion of the printed circuit board 32 that you do not want to come into contact with the magnet wire 36. Both sides of the lint wiring 30 (printed wiring in the direction in which the magnet wire 36 is stretched) Through-holes 40 are provided on both sides of 30. In addition, the outer peripheral edge of the printed circuit board 32 A plurality of notches 42 are carved in the. On the other hand, a plurality of hooks 44 are provided upwardly on the outer peripheral edge of the substrate holder 28. ing. The position of the hook 44 corresponds to the notch 42 of the printed circuit board 32. Therefore, when fitting the printed circuit board 32 into the board holder 28, the tip of the hook 44 is cut off. The printed circuit board 32 can be fixed to the board holder 28 by engaging with the notch 42 . Also, the upper surface of the board holder 28, when the printed circuit board 32 is fitted, is An upstanding piece 46 that can be inserted into the through hole 40 is provided at a position corresponding to the through hole 40 of the lint board 32. is erected upwards. Distance by which the standing piece 46 protrudes from the top surface of the printed circuit board 32 d (insulation distance) may be appropriately determined as necessary. There is a slot at the upper end of the standing piece 46. A groove 48, which is an example of a stop means, is carved in the direction in which the magnet wire 36 is stretched. Ru. The magnet wire 36 passes through this groove 48 and is stretched. It is prevented from shifting by the inner wall surface.

[0008] In order to form the substrate section 18 having the above configuration, first the printed circuit board 32 is The magnet wire 36 that is fitted into the holder 28 and then pulled out from the coil 22 is The magnet wire 36 is stretched through the groove 48 of each standing piece 46, and the tip of the magnet wire 36 is rounded. solder to the board 38. As a result, the magnet wire stretched between the standing pieces 46 36 is separated from the printed wiring 30 between the upstanding pieces 46, and is connected to an insulating tube or insulation tube. It is possible to insulate both without using a loop. Note that the lead wire 34 Connection is made by threading the lead wires 3 through each hole 50 after assembling the board 18. 4 After holding the position by its own elasticity and the frictional force acting on the lead wire 34, The tip of the wire 34 may be soldered to the round 38. Next, another embodiment will be described with reference to FIG. Note that the same components as in the previous embodiment The same reference symbols will be given to the materials, and the explanation will be omitted. In the previous embodiment, the upright piece 46 was formed into a plate (wall) shape (see FIG. 2). In this embodiment, the upright piece 46 is formed into a rod (pin) shape. As expected, it is erected A groove 48 is carved in the upper end of the piece 46 as a slip prevention means, and a magnet is inserted into the groove 48. A twine wire 36 is stretched.

[0009] In addition, although not shown, the board section 18 does not necessarily include the printed circuit board 32 and the board holder 2. It does not have to be a type that is divided into 8 parts. Furthermore, the board section 18 is connected to the printed circuit board 32. In the type that is divided into the board holder 28 and the board holder 28, the standing piece 46 of the printed circuit board 32 is The part to be inserted may be a notch instead of the through hole 40, or a combination of a through hole and a notch. It may be. Various preferred embodiments of the present invention have been described above, but the present invention is For example, but not limited to, conductive wires other than magnet wires of AC motors. Further modifications may be made without departing from the spirit of the invention. Of course, changes can be made.

[Effect of the idea]

When the holding mechanism of the conductive wire according to the present invention is used, at least one pair When a standing piece is provided, the upper part of the standing piece is separated from a predetermined part of the board, so a pair of standing pieces are provided. Just by stretching the conductive wire between the upper parts of the installation pieces, the conductive wire can be made non-contact with the specified part. Since wiring is possible, it is advisable to apply insulating tape or , there is no need to cover the conductive wire with an insulating tube. Therefore, it is easy to connect conductive wires. Wiring can be done without contacting the specified part of the board, improving the efficiency of assembly work. It has great effects, such as being able to
