  The electric motor 100 is provided with a wiring extraction unit 10 for extracting the three wirings 20 corresponding to each phase to the outside of the casing 4. The wiring extraction portion 10 is provided between the flange 6 and the flange cover 7. Each wiring 20 is taken out so as to extend in the Y-axis direction. The wirings 20 are arranged so as to be arranged with a certain interval in the X-axis direction.

  The wiring take-out portion 10 is provided with a resin-made holding member 30 and a pressing member 40 that sandwich each wiring 20. The flange 6, the holding member 30, the pressing member 40, and the flange cover 7 are attached to the case 5 while being stacked in the Z-axis direction.

  FIG. 2 shows an exploded state in which the flange cover 7 and the pressing member 40 are removed from the flange 6. The flange 6 is formed with an opening 61 in which the holding member 30 and the pressing member 40 are interposed. The opening 61 has a bottom surface on which the holding member 30 is placed and both side surfaces that come into contact with both sides of the holding member 30. A pair of positioning grooves 62 extending opposite to each other are opened on both side surfaces of the opening 61. The positioning groove 62 is disposed so as to extend in directions (X-axis direction and Z-axis direction) substantially orthogonal to the extending direction of the wiring 20 (Y-axis direction).

  3 and 4 show a state in which each wiring 20 is sandwiched between the holding member 30 and the pressing member 40. A pair of rail portions 38 extending in the Z-axis direction are formed on both sides of the holding member 30. A pair of rail portions 48 are formed on both sides of the pressing member 40. The holding member 30 and the pressing member 40 are restricted from moving in the extending direction (Y-axis direction) of the wiring 20 when the rail portions 38 and 48 engage with the positioning grooves 62 of the flange 6.

  One end 38A of the rail portion 38 is formed in a tapered shape. Thereby, when the holding member 30 is assembled to the flange 6, the rail portion 38 is smoothly inserted into the positioning groove 62 via the tapered tip 38 </ b> A.

  Three conductive plates 17 corresponding to each phase are interposed in the holding member 30. As shown in FIG. 7, each conductive plate 17 is fixed by being inserted into the fixed beam portion 55 of the holding member 30. The fixed beam portion 55 is formed in a beam shape extending in the X-axis direction. The conductive plate 17 is formed in a plate shape bent into an L shape. A conductive wire 21 of the wiring 20 is coupled to one end of the conductive plate 17 extending in the Y-axis direction by welding. A conductive wire 18 extending from the electromagnetic coil of the stator is coupled to the other end of the conductive plate 17 extending in the Z-axis direction by welding or caulking. The conductive wire 18 is coupled to the conductive plate 17 through a tapered hole 30 </ b> A formed in the holding member 30 and a hole 17 </ b> A formed in the bent portion of the conductive plate 17. When the electric motor 100 is operated, a drive current is supplied to the electromagnetic coil of the stator through the conductive wire 21, the conductive plate 17, and the conductive wire 18 of the wiring 20.

  The holding member 30 has two partition walls 56 that partition between the conductive wires 21 of the adjacent wirings 20. The partition wall 56 has a plate shape extending in the X-axis direction and the Z-axis direction, and one end of the partition wall 56 is connected to the fixed beam portion 55. When the electric motor 100 is operated, the drive current flowing through the conductive wire 21 and the conductive plate 17 of the wiring 20 is insulated by the partition wall 56 and the fixed beam portion 55.

  A plurality of lightening portions 57 and 58 are formed in the holding member 30 (see FIG. 7). A plurality of (here, five) lightening portions 50 are also formed in the pressing member 40. Thereby, the shape of the holding member 30 and the pressing member 40 is maintained at the time of molding of the resin holding member 30 and the pressing member 40.

  FIG. 5 shows an assembled state of the wiring take-out unit 10 in which the illustration of each wiring 20 is omitted. FIG. 6A is an enlarged view of a part of FIG. A gap 15 is provided between the end surface 36 of the holding member 30 and the end surface 46 of the pressing member 40 in a state where the wiring 20 is sandwiched between the holding member 30 and the pressing member 40. As described above, the holding member 30 and the pressing member 40 are formed so as not to contact each other, and the pressing force applied to the wiring 20 between the holding member 30 and the pressing member 40 is not limited.

  The holding member 30 is formed with a seal protrusion 35 protruding from the end surface 36 thereof. On the other hand, the pressing member 40 is formed with a seal recess 45 that opens to the end surface 46 thereof. The seal convex portion 35 and the seal concave portion 45 are arranged so as to extend in directions (X axis direction and Z axis direction) substantially orthogonal to the extending direction (Y axis direction) of the wiring 20. In the wiring extraction portion 10, the gap 15 is blocked by the seal convex portion 35 fitting into the seal concave portion 45. The seal convex portion 35 is formed so that both ends thereof protrude from the end surface of each rail portion 38. On the other hand, the seal recess 45 is formed so that both ends thereof open to the end surfaces of the rail portions 48. Thus, no gap is generated between the outside of the electric motor 100 and the opening 61 of the flange 6, and entry of foreign matters such as dust and dust into the electric motor 100 is suppressed.

  FIG. 7 is a cross-sectional view taken along the line AA in FIG. 5 and shows a state in which the wiring 20 is sandwiched between the holding member 30 and the pressing member 40 in the wiring extraction portion 10.

  The wiring 20 includes a conductive wire (stranded wire) 21 made of a plurality of wires, and a resin coating 22 surrounding the conductive wire 21. In FIG. 7, O indicates the center line of the wiring 20. In a free state where the wiring 20 is not subjected to external force, the coating 22 extends in a right cylindrical shape.

  As shown in FIG. 5, the holding member 30 has three holding grooves 31 that open to the end surface 36. The holding groove 31 has a semi-cylindrical holding surface (inner peripheral surface) 32 extending in the Y-axis direction. On the other hand, the pressing member 40 has a pressing groove 41 that opens in the end face 46. The holding groove 41 has a holding surface (inner peripheral surface) 42 having a semi-cylindrical shape extending in the extending direction (Y-axis direction) of the wiring 20 so as to face the holding surface 32. The holding surface 32 and the pressing surface 42 define a right cylindrical through hole extending in the extending direction of the wiring 20 (Y-axis direction). Since the wiring 20 is sandwiched between the holding groove 31 and the pressing groove 41, the coating 22 of the wiring 20 is compressed between the holding surface 32 and the pressing surface 42.

  As shown in FIGS. 5 and 6A, the holding member 30 has two first protrusions 33 protruding from the holding surface 32. The first protrusion 33 has a semicircular cross-sectional shape protruding in the radial direction (Z-axis direction) from the holding surface 32 (see FIG. 7), and is formed in a rib shape extending in the circumferential direction of the holding surface 32. . The two first protrusions 33 are arranged at intervals in the extending direction (Y-axis direction) of the wiring 20 and are provided as pressing portions (convex portions) that partially press the wiring 20.

  The pressing member 40 has one second protrusion 43 that protrudes from the pressing surface 42. The second protrusion 43 has a semicircular cross-sectional shape protruding in the radial direction (Z-axis direction) from the pressing surface 42 (see FIG. 7), and is formed in a rib shape extending in the circumferential direction of the pressing surface 42. . The second protrusion 43 is disposed near the central portion in the longitudinal direction of the pressing groove 41 and is provided as a pressing portion (convex portion) that partially presses the wiring 20.

  In the wiring take-out portion 10, each of the first protrusions 33 and the second protrusions 43 extends in the extending direction of the wiring 20 (Y-axis direction) as a configuration in which the wiring 20 sandwiched between the holding groove 31 and the holding groove 41 is curved. ) Are offset from each other. The second protrusion 43 is disposed so as to face the intermediate position of each first protrusion 33.

  When the electric motor 100 is assembled, after the holding member 30, each wiring 20, the pressing member 40, and the flange cover 7 are assembled to the flange 6, the flange 6 and the flange cover 7 are fastened via the bolts 3. At this time, as the pressing member 40 is attracted to the holding member 30 by the fastening force of each bolt 3, the first protrusion 33 and the second protrusion 43 form the outer circumference of the wiring 20 in the radial direction (Z-axis direction). ). The wiring 20 is bent at three locations of the wiring 20 by applying bending loads at different positions in the extending direction (Y-axis direction) of the wiring 20 by the first protrusions 33 and the second protrusions 43. . Since the second protrusions 43 are arranged so as to face the intermediate positions of the first protrusions 33, the wiring 20 has the second protrusions 43 and the first protrusions 33 that are equally spaced from each other as fulcrums. Effectively curved.

  Thus, in the assembled state of the electric motor 100, the wiring 20 is curved, and the curved portion of the wiring 20 becomes a resistance against the force by which the wiring 20 is pulled to the outside, and the wiring 20 is inserted between the holding groove 31 and the pressing groove 41. Is prevented from coming off.

  Note that the shape, the number, and the arrangement of the first protrusions 33 and the second protrusions 43 are not limited to the above-described configuration, and may be any as long as a bending load is applied to the wiring 20.

  According to the above 1st Embodiment, there exists an effect shown below.

The holding member 30 has a holding groove 31 that is recessed along the extending direction of the wiring 20, and the pressing member 40 has a holding groove 41 that is recessed along the extending direction of the wiring 20. Then, at least one of the holding groove 31 and the holding groove 41 is provided with a first protrusion 33 and a second protrusion 43 (pressing part) that press and curve the wiring 20.

  Based on the above configuration, the wiring 20 is pressed and curved by the first protrusion 33 and the second protrusion 43 (pressing portion) while being held between the holding member 30 and the pressing member 40. Therefore, the curved portion of the wiring 20 becomes a resistance against the force that pulls the wiring 20 to the outside, and the wiring 20 is prevented from coming off between the holding groove 31 and the holding groove 41.

  [5] The wiring extraction unit 10 includes a flange 6 and a flange cover 7 that are stacked on each other. The holding member 30 and the pressing member 40 are configured to be sandwiched between the flange 6 and the flange cover 7.

  The resin holding member 30 and the pressing member 40 are not directly fastened by screws or the like, but are sandwiched between the highly rigid metal flange 6 and the flange cover 7. Therefore, since the holding member 30 and the pressing member 40 are pressed at the contact surfaces with the flange 6 and the flange cover 7, it is possible to suppress the bias applied to the wiring 20. Thereby, the wiring 20 is effectively curved and the wiring 20 is prevented from coming off.

  As shown in FIG. 6B, the first protrusion 33 </ b> A is formed on the holding member 30 and the second protrusion is formed on the pressing member 40 as a pressing portion that partially presses in the circumferential direction of the wiring 20. 43A may be formed.

The second protrusion 43 </ b> A is disposed at the bottom (back part) of the pressing groove 41 and is formed in a linear shape extending in the X-axis direction so that its protruding end is parallel to the end surface 46 of the pressing member 40.

  In this case, the first protrusion 33A partially protrudes from the semi-cylindrical holding surface 32, and the second protrusion 43A partially protrudes from the semi-cylindrical holding surface 42. Therefore, the load which presses the wiring 20 between both can be made small. Thereby, the operation | work which attaches the holding member 40 on both sides of the wiring 20 in the holding member 30 can be performed easily. By arranging the first protrusion 33A and the second protrusion 43A so as to be arranged in the Z-axis direction in which the pressing member 40 is displaced with respect to the holding member 30 with the wiring 20 interposed therebetween, the wiring 20 is effectively curved. The wiring 20 is prevented from coming off.

  As shown in FIG. 6C, the first protrusion 33 </ b> B is formed on the holding member 30 and the second protrusion is formed on the pressing member 40 as a pressing portion that partially presses in the circumferential direction of the wiring 20. 43B may be formed. The first protrusion 33B is disposed at the bottom (back part) of the holding groove 31 and is formed in a wedge shape with a protruding end protruding in a square shape. The 2nd protrusion 43B is arrange | positioned at the bottom part (back part) of the pressing groove 41, and the protrusion end is formed in the wedge shape which protrudes squarely.

  In this case, the first protrusion 33B and the second protrusion 43B having a wedge shape bite into the coating 22 of the wiring 20, and the wiring 20 is prevented from coming off. By forming the protruding amount of the first protrusion 33B and the second protrusion 43B smaller than the thickness of the coating 22 of the wiring 20, the conductive line 21 of the wiring 20 is prevented from being damaged.
