And a coil is connected to the output terminal portion.
  According to the present invention, an insulating layer for insulating plate members from each other is not required separately from the exterior material, and can be configured at low cost.
-First embodiment-
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a plan view showing the overall configuration of the wiring sheet according to the first embodiment, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG. The wiring sheet 100 is used as, for example, a power supply line for an electric motor, and FIGS. 1 and 2 show a state before the use. The wiring sheet 100 includes a plurality of strip plates (three rows in the figure) bus bars 11 to 13 arranged in parallel at a predetermined distance, and a sheet film 2 covering the entire bus bars. The bus bars 11 to 13 are made of a conductive metal (such as copper). The sheet film 2 is made of an electrically insulating and flexible material such as a synthetic resin.
  As shown in FIG. 2, the sheet film 2 is bent at the central portion 2 a and covers the upper and lower surfaces of the bus bars 11 to 13, the intermediate portion 2 b of the bus bars 12 and 13, the intermediate portion 2 c of the bus bars 12 and 11, The upper side and the lower side are thermally welded at the end 2d of the film 2, respectively. As a result, the sheet film 2 is individually wrapped and laminated with the bus bars 11 to 13, and the bus bars are electrically insulated from each other by the sheet film 2. In addition, although the terminal part is provided in the edge part of the bus-bars 11-13 exposed from the sheet film 2, respectively, illustration of the terminal part is abbreviate | omitted in FIG.
  FIG. 3A is a diagram illustrating a usage state of the wiring sheet 100, and FIG. 3B is a cross-sectional view taken along the line bb of FIG. 3A. When the wiring sheet 100 is used, the sheet film 2 is bent between the bus bars 11 and 12 and between the bus bars 12 and 13. That is, valley folding is performed at the folding line L1 at the center of the intermediate portion 2c, and mountain folding is performed at the folding line L2 at the center of the intermediate portion 2b, and the bus bars 11 to 13 are laminated via the film 2 as shown in FIG. Thereby, the width W of the entire wiring sheet having the plurality of rows of bus bars 11 to 13 can be reduced, and the wiring sheet 100 can be easily attached as a power supply line to a narrow space.
According to 1st Embodiment, there can exist the following effects.
(1) The bus bars 11 to 13 arranged in parallel were individually encased by one sheet film 2 and then bent at the folding lines L1 and L2 to constitute the laminated wiring sheet 100. Thereby, since the bus bars 11 to 13 are laminated in a state where they are insulated by the sheet film 2, it is not necessary to separately provide an insulating layer other than the film 2, and can be configured at low cost.
(2) The width W of the wiring sheet 100 after bending can be set to the same level as the width of a single bus bar, and the wiring sheet 100 can be easily attached to a narrow space.
-Second Embodiment-
A second embodiment of the present invention will be described with reference to FIGS.
In 2nd Embodiment, the example which provides a terminal in the bus-bars 11-13 is shown. FIG. 4 is a plan view showing a configuration before bending of the wiring sheet 100 according to the second embodiment, and FIGS. 5A and 5B are a side view and a plan view showing the configuration after bending, respectively. It is. In addition, the same code | symbol is attached | subjected to the location same as FIGS. 1-3, and the difference with 1st Embodiment is mainly demonstrated below.
  As shown in FIG. 4, a plurality (three in the figure) of terminals 11 a to 13 a project from the edges of the bus bars 11 to 13 in the direction perpendicular to the folding lines L <b> 1 and L <b> 2 along the longitudinal direction. . The terminal 11 a of the bus bar 11 protrudes outward from the end 2 d of the film 2. On the other hand, the terminals 12a and 13a of the bus bars 12 and 13 are provided on folding lines L2 that are mountain-folded, respectively. A hole 21 that is slightly larger than the terminals 12a and 13a is previously opened in the intermediate portion 2b of the film 2 where the terminals 12a and 13a are located, and the terminals 12a and 13a are exposed from the film 2 through the holes 21.
  The terminals 11a to 13a of the bus bars 11 to 13 are alternately provided along the longitudinal direction of the bus bars 11 to 13, respectively. That is, in FIG. 4, terminals 13a, 12a, 11a, 13a,... Are provided in order from the left side, and the terminals 11a to 13a are provided at different positions in the longitudinal direction.
  When the sheet film 2 of FIG. 4 is bent along the folding lines L1 and L2, the terminals 11a to 13a of the bus bars 11 to 13 project from the one end of the film 2 in the same direction as shown in FIG. At this time, the positions of the terminals 11a to 13a of the bus bars 11 to 13 are shifted from each other in the longitudinal direction, and contact between the terminals 11a to 13a can be prevented.
  As described above, in the second embodiment, the terminals 11a to 13a are projected from the edges of the bus bars 11 to 13, and the holes 21 are opened in the sheet film 2 in accordance with the positions of the terminals 12a and 13a. . Thereby, the terminals 11a-13a protrude from the edge part of the film 2 in the state which bent the sheet | seat film 2, and the connection of the terminals 11a-13a, a cable, etc. is easy. Since the holes 21 are previously opened in the sheet film 2 in accordance with the positions of the terminals 12a and 13a, the bus bars 11 to 13 may be set in the sheet film 2 with the holes 21 as a reference when the wiring sheet 100 is manufactured. Manufacture of the sheet 100 is easy.
  4 and 5 show an example in which the terminals 11a to 13a are provided in the three rows of bus bars 11 to 13, the terminals can be provided in four rows of bus bars. 6 is a plan view showing a configuration before bending of the wiring sheet 100 having four rows of bus bars 11 to 14, and FIGS. 7A and 7B are diagrams showing the configurations before and after the bending, respectively. 6 is a sectional view taken along line VII-VII in FIG.
  Also in FIG. 6, holes 21 are opened in the sheet film 2 corresponding to the terminals 12 a and 13 a located in the intermediate portion 2 b that is mountain-folded. Moreover, in FIG. 6, the terminal 14a protrudes from the edge part of the bus bar 14, and the hole 21 is opened also in the center part 2a of the sheet film 2 corresponding to the terminal 14a. The terminals 11a to 14a are provided alternately along the longitudinal direction of the bus bars 11 to 14, respectively. Thus, when the sheet film 2 is bent, the terminals 11a to 14a protrude from the end portions of the sheet film 2 at different positions in the longitudinal direction, as shown in FIG.
  4 and 5, the sheet film 2 is folded at the center folding lines L1 and L2 of the intermediate portions 2b and 2c to stack the bus bars 11 to 13, but the positions of the folding lines L1 and L2 are centered. The bus bars 11 to 13 may be stacked while being shifted. For example, as shown in FIG. 8, the folding lines L1 and L2 may be translated to the bus bar 12 side, and the sheet film 2 may be folded along the folding lines L11 and L12. Thereby, when the sheet film 2 is bent as shown in FIG. 9A, a step is generated in the height of the terminals 11-13. For this reason, as shown in FIG.9 (b), the creeping distance S between the terminals 11-13 can be increased compared with what folded the sheet | seat film 2 by bending line L1, L2.
-Third embodiment-
A third embodiment of the present invention will be described with reference to FIGS.
In 3rd Embodiment, the example which attaches the sheet | seat 100 for wiring to an electric motor is shown. FIG. 10 is a plan view showing a configuration before bending of the wiring sheet 100 according to the third embodiment, and FIG. 11A is a diagram showing a usage state of the wiring sheet 100. FIG. ) Is a cross-sectional view taken along line bb of FIG. In addition, the same code | symbol is attached | subjected to the location same as FIG.
  In 3rd Embodiment, the bus-bars 11-13 are functioned as a feed line which guides the electric power for U phases, V phases, and W phases to the coil of a stator. For this reason, the number of terminals 11a to 13a corresponding to the coil 203 (FIG. 12) and the terminals 11b to 13b for power supply are provided at the edges of the bus bars 11 to 13. As shown in FIG. 10, the terminals 11 a to 13 a are alternately provided along the longitudinal direction, but the bus bars 11 to 13 extend only to the positions of the terminals 11 a to 13 a at the ends in the longitudinal direction. There are steps at the ends of ˜13.

The wiring sheet 100 described above is disposed on the outer peripheral end of the stator core 201, and the terminals 11 a to 13 a of the wiring sheet 100 are connected to one end of the coil 203. The other end portions of the coil 203 are connected to each other to be a neutral point.
  Three-phase alternating current from the inverter 206 is applied to the terminals 11b to 13b. As a result, a current flows through each coil 203 via the bus bars 11 to 13, a rotating magnetic field is generated around the rotor 205, and the rotor 205 rotates.
  As described above, in the third embodiment, the bus bars 11 to 13 of the wiring sheet 100 are configured as U-phase, V-phase, and W-phase bus bars, respectively, and the terminals 11a to 13a of the bus bars 11 to 13 are connected. Since it is connected to the coil 203, the three-phase alternating current from the inverter 206 can be applied to the coil 203. At this time, since the sheet film 2 is bent and the bus bars 11 to 13 are laminated, the axial length (width) of the entire wiring sheet when the wiring sheet 100 is arranged along the outer peripheral surface of the stator core 201 is Since it is short and relatively thin, the wiring sheet 100 can be easily arranged in a narrow space.
  The stator core 201 includes a stator 200 (stator) around which a plurality of coils 203 are wound, and a rotor 205 (rotor) that is rotatably supported inside the coil 203, and includes a terminal 11a of the wiring sheet 100. If the coil 203 is connected to ~ 13a (output terminal part) and the inverter 206 or the like is connected to the terminals 11b to 13b (input terminal part) to generate a rotating magnetic field in the coil 203, then the motor The electric motor may have any configuration.
  In the first to third embodiments, the substantially rectangular bus bars 11 to 13 are arranged in parallel to configure the wiring sheet 100. However, the shape of the bus bars 11 to 13 as plate members is not limited thereto. . The shape of the sheet film 2 as the exterior material may be any as long as it covers the entire surface of the plurality of bus bars 11 to 13 and encloses each of the bus bars 11 to 13 and electrically insulates them individually. In the second embodiment, the terminals 11a to 13a are provided as the terminal portions along the longitudinal direction of the bus bars 11 to 13, but the terminal portions may be provided at both ends of the bus bars 11 to 13.
  The sheet film 2 is folded at the intermediate portions 2b and 2c (folded portions) of the bus bars 11 to 13 and the bus bars 11 to 13 are stacked one by one, but only a part of the intermediate portions (for example, only the intermediate portion 2b). The sheet film 2 may be bent. That is, as the number of bus bars increases, the number of laminations also increases. Therefore, the sheet film 2 may be bent only at some intermediate portions in order to suppress the number of laminations. Although the hole 21 was previously opened as an opening in the intermediate portion b2 of the sheet film 2 to be folded, and the terminals 12a and 13a protruded from the hole 21, the configuration of the opening is not limited to that described above.
  In the said 3rd Embodiment, although the sheet | seat 100 for wiring was applied to the electric motor, the sheet | seat 100 for wiring can be applied similarly to another electric equipment. That is, the present invention is not limited to the wiring sheet of the embodiment as long as the features and functions of the present invention can be realized.
