  However, when the lead wire is bent when the lead wire member is disposed inside the drive unit, a load may be applied to the lead wire and a break may occur. Further, in the technology described in Patent Document 1, since the sensor terminal is formed narrow at the flexible portion, it is easy to use for a long time under vibration environment such as operation of the rotating electric machine. The strength of the bent portion may be insufficient to cause a break.

  Then, this invention provides the conducting-wire member which can suppress a disconnection, and a drive unit.

  The wire member of the present invention (for example, the wire member 70 in the embodiment) has a rotating electrical machine (for example, the generator 30 and the motor 40 in the embodiment) and a housing (for example, the housing 10 in the embodiment) for accommodating the rotating electrical machine A conductor member provided in a drive unit (for example, drive unit 1 in the embodiment), and one end connector portion (for example, internal connector portion 71 in the embodiment) connected to a mating connector provided in the housing And connecting the other end connector portion (for example, the external connector portion 72 in the embodiment) provided at the end opposite to the one end connector portion, the one end connector portion and the other end connector portion, Connecting portion (for example, a bending portion (for example, bending portions 74, 75, 76 in the embodiment) is formed in the portion (E.g., the connecting portion 73) in the embodiment, and the one end connector portion, the other end connector portion, and the connecting portion are a conductive wire (e.g., the conductive wire 81 in the embodiment) and a hard resin (e.g. , And the hard resin 82) in the embodiment.

  According to the present invention, since the conducting wire is fixed in advance by the hard resin at the bending portion, when arranging the conducting wire member inside the drive unit and connecting the one end connector portion to the mating connector, the conducting wire is used as in the prior art. It is possible to avoid the occurrence of bending work. As a result, the conductive wire is prevented from being loaded at the bending portion. Therefore, disconnection of the conducting wire can be suppressed.

  In the above conductor member, at least one of the one-end connector portion and the other-end connector portion is a connection terminal connected to the conductor and partially exposed from the hard resin (for example, connection in the embodiment) It is desirable that a terminal 83) be provided, and the bent portion be connected to the one connector portion.

  According to the present invention, as compared with the case where the bending portion is provided apart from the one end connector portion and the other end connector portion, the connection portion between the conducting wire and the connection terminal is closer to the bending portion. It is possible to suppress the disconnection of the conducting wire at the connection portion between the conducting wire and the connection terminal by suppressing the load from being applied.

  In the above-mentioned wire member, it is desirable that a plurality of the one-end connector portions be provided.

  According to the present invention, since the connecting portion is formed in a complicated shape as compared with the case where one end connector portion is provided, the above configuration suppresses the load applied to the conducting wire at the bent portion. , It can control the disconnection of the lead.

  In the above-described wire member, it is preferable that the connection portion be provided with a fixing portion (for example, a fixing portion 78 in the embodiment) fixed to the housing.

  According to the present invention, the conductor member can be easily positioned in the drive unit. Moreover, compared with the case where a conducting wire member is supported only by the one end connector part and the other end connector part, it becomes difficult to vibrate a conducting wire member. Therefore, the disconnection of the conducting wire can be more reliably suppressed under the vibration environment such as the operation of the rotary electric machine.

  The drive unit (for example, drive unit 1 in the embodiment) of the present invention detects at least one of the above-described wire member, the rotating electric machine, the housing, and the rotation angle and the rotation speed of the rotating machine. The resolver (for example, the first resolver 50 and the second resolver 60 in the embodiment) is provided, and the one end connector portion is connected to the resolver.

  According to the present invention, since the lead wire member in which the breakage of the lead wire is suppressed is provided, a highly reliable drive unit can be provided.

  In the drive unit described above, a first one of the rotating electrical machines (for example, the generator 30 in the embodiment), and a second coaxially arranged with the first rotating electrical machine and aligned in the axial direction of the first rotating electrical machine The rotary electric machine (for example, the motor 40 in the embodiment), the first rotary electric machine and the second rotary electric machine, and at least one of the rotation angle and the rotation speed of the first rotary electric machine The first rotary resolver (for example, the first resolver 50 in the embodiment) for detecting any one, and the second rotary electric machine disposed between the first rotary electric machine and the second rotary electric machine A second resolver (for example, the second resolver 60 in the embodiment) for detecting at least one of the rotation angle and the rotation speed of the first conductive member; A first one end connector portion (for example, the first internal connector portion 71A in the embodiment) connected to the solver, and a second one end connector portion (for example, the second interior in the embodiment) connected to the second resolver It is desirable that the connector portion 71B) is provided.

  According to the present invention, the conducting wire member connected to the first resolver and the second resolver is disposed between the first rotating electrical machine and the second rotating electrical machine. Here, even when the distance between the first rotating electrical machine and the second rotating electrical machine is narrow, it is possible to avoid the occurrence of the work of bending the conducting wire when arranging the conducting wire member as described above. Therefore, the distance between the first rotating electric machine and the second rotating electric machine is narrow, which is suitable for an axially miniaturized drive unit.

The flat extension portion 77 is provided with a fixing portion 78 fastened and fixed to the partition wall 14 of the first case 11.

FIG. 3: is sectional drawing which shows typically the structure of the conducting-wire member of embodiment.
As shown in FIG. 3, the internal connector portion 71, the external connector portion 72 and the connecting portion 73 are integrally formed of a plurality of conducting wires 81 and a hard resin 82 covering the plurality of conducting wires 81. The inner connector portion 71, the outer connector portion 72 and the connecting portion 73 are integrally formed by molding. In addition, the internal connector portion 71 and the external connector portion 72 are provided with connection terminals 83 which are connected to the plurality of conducting wires 81 and which are partially exposed from the hard resin 82. The connection terminal 83 of the internal connector 71 is electrically connected to the connection terminal of the signal extracting unit 54 (see FIG. 2). The connection terminal 83 of the external connector portion 72 is electrically connected to, for example, the connection terminal of the cable member described above. The plurality of conducting wires 81 are, for example, copper wires or the like. The plurality of conducting wires 81 connect the first conducting wire 81a connecting the connection terminal 83 of the first internal connector 71A and the connecting terminal 83 of the external connector 72, and the connection 83 of the second internal connector 71B and the external connector 72 And a second conducting wire 81 b connecting the terminal 83. Although two first conductors 81a and two second conductors 81b are illustrated in FIG. 3, the number of first conductors 81a and second conductors 81b is not particularly limited.

Here, with reference to FIG. 2, the shapes of the plurality of conducting wires 81 in the hard resin 82 will be described. In addition, in FIG. 2, in order to make it intelligible, one each of the 1st conducting wire 81a and the 2nd conducting wire 81b is illustrated.
As shown in FIG. 2, the first conducting wire 81 a extends radially outward from the connection portion with the connection terminal 83 (see FIG. 3) in the first internal connector portion 71 A, and enters the first bent portion 74. The first conducting wire 81a is bent toward the second resolver 60 in the axial direction in the first bending portion 74, and is further bent in the direction away from the second internal connector portion 71B in the circumferential direction. Then, the first conducting wire 81 a enters the planar extending portion 77.

  The second conducting wire 81 b extends radially outward from the connection terminal 83 (see FIG. 3) in the second inner connector portion 71 B, and enters the second bent portion 75. The second conducting wire 81b is bent toward the first resolver 50 in the axial direction in the second bending portion 75, and is further bent toward a direction approaching the first inner connector portion 71A in the circumferential direction. Then, after the second conducting wire 81b enters the first bent portion 74, the second conducting wire 81b enters the planar extending portion 77 in parallel with the first conducting wire 81a.

  The first conducting wire 81 a and the second conducting wire 81 b linearly extend radially outward in the planar extending portion 77. The first conducting wire 81 a and the second conducting wire 81 b enter the third bent portion 76 from the radial outer end of the plane extending portion 77. The first conducting wire 81 a and the second conducting wire 81 b extend in the circumferential direction at the third bending portion 76 and then bend toward the first resolver 50 in the axial direction. Furthermore, the first conducting wire 81a and the second conducting wire 81b are bent in the circumferential direction and then bent outward in the radial direction. The first conducting wire 81a and the second conducting wire 81b enter the external connector portion 72 and are connected to the connection terminal 83 (see FIG. 3).

  As described above, in the present embodiment, a configuration is adopted in which the internal connector portion 71, the external connector portion 72, and the connecting portion 73 are integrally formed of the conductive wire 81 and the hard resin 82 that covers the conductive wire 81. According to this configuration, since the conducting wire 81 is fixed in advance by the hard resin 82 at the bending portions 74, 75, 76, the conducting member 70 is disposed inside the drive unit 1 and the internal connector portion 71 is taken as the signal extracting portion 54, When connecting to 64, it is possible to avoid the occurrence of the work of bending the lead as in the prior art. Therefore, load applied to the conducting wire 81 at the bent portions 74, 75, 76 is suppressed, and disconnection of the conducting wire 81 can be suppressed. Further, since the work of connecting while twisting the lead 70 can be omitted, the working efficiency at the time of assembling the drive unit 1 can be improved.

  The bent portions 74, 75, 76 are connected to the internal connector portion 71 or the external connector portion 72. Therefore, as compared with the case where the bending portion is provided apart from the inner connector portion and the outer connector portion, the connecting portion between the conducting wire 81 and the connection terminal 83 is closer to the bending portion 74, 75, 76, so bending is performed. By suppressing load on the conducting wire 81 in the portions 74, 75, 76, disconnection of the conducting wire 81 at the connection portion between the conducting wire 81 and the connection terminal 83 can be suppressed.

  Moreover, the internal connector part 71 is provided with two or more. For this reason, as compared with the case where one internal connector portion is provided, the connecting portion 73 is formed in a complicated shape, so that the conductive wire 81 is prevented from being loaded at the bent portions 74, 75, 76 by the above configuration. As a result, disconnection of the conducting wire 81 can be suppressed.

  Further, the connecting portion 73 is provided with a fixing portion 78 which is fastened and fixed to the housing 10 (the partition portion 14 of the first case 11). For this reason, the conducting wire member 70 can be easily positioned in the drive unit 1. Further, the conductive member 70 is less likely to vibrate as compared with the case where the conductive member is supported only by the inner connector portion and the outer connector portion. Therefore, disconnection of the conducting wire 81 can be more reliably suppressed in a vibration environment such as when the generator 30 or the motor 40 operates.

  And according to this embodiment, by providing the conducting wire member 70, the highly reliable drive unit 1 in which the disconnection of the conducting wire 81 is suppressed can be provided.

  Furthermore, the drive unit 1 includes a generator 30 and a motor 40, and a first resolver 50 and a second resolver 60 disposed between the generator 30 and the motor 40. The conductor member 70 is connected to the first resolver 50 and the second resolver 60. For this reason, the wire member 70 is disposed between the generator 30 and the motor 40. Here, even when the distance between the generator 30 and the motor 40 is narrow, it is possible to avoid the operation of bending the conducting wire 81 when arranging the conducting wire member 70 as described above. Therefore, the distance between the generator 30 and the motor 40 is narrow, and it is suitable for the drive unit 1 miniaturized in the axial direction.

The present invention is not limited to the above-described embodiment described with reference to the drawings, and various modifications can be considered within the technical scope.
For example, although the drive unit 1 includes the generator and the motor in the above embodiment, the present invention is not limited to this. For example, the drive unit may include only one of the generator and the motor. The motor may be provided.

  Moreover, in the said embodiment, although the pair of internal connector parts 71 are provided in the conducting-wire member 70, one internal connector part may be provided and three or more may be provided. The same applies to the external connector section 72.

Moreover, in the said embodiment, although the external connector part 72 which comprises the other end part of the conducting-wire member 70 is provided in the outer side of the housing 10, it is not limited to this. The connector portion constituting the other end portion of the conducting wire member 70 may be configured to be connected to a connector provided in the housing 10, as with the internal connector portion 71.

  In addition, without departing from the spirit of the present invention, it is possible to replace components in the above-described embodiment with known components as appropriate.
