Detailed Embodiment

[0010] [Description of Embodiment of the Present Invention] First, embodiments of the present invention will be described by way of example.

[0011] The terminal block module of the present invention is as follows.

[0012] (1) A terminal block module fixed to the equipment housing of a rotating electric machine equipped with a temperature sensor, the terminal block module comprising: a connection member for electrically connecting an inner bus bar terminal inside the equipment housing and an outer bus bar terminal outside the equipment housing; a terminal block main body fixed to the equipment housing in a state of holding the connection member; an internal connector for a temperature sensor having an inner terminal for a temperature sensor supported by the terminal block main body so as to be located inside the equipment housing; and a wiring for a temperature sensor, at least a part of which is held inside the terminal block main body, connecting the inner terminal for a temperature sensor to a circuit from outside the equipment housing.

[0013] According to the present invention, if the terminal block main body for holding the connection member is fixed to the device housing, the internal connector for the temperature sensor is disposed within the device housing. If the temperature sensor is connected to the internal connector for the temperature sensor, the temperature sensor is connected to the wiring outside the rotating electric machine via the wiring for the temperature sensor. Therefore, it is possible to easily connect the temperature sensor installed in the rotating electric machine to the wiring outside the rotating electric machine.

[0014] (2) In the terminal block module of (1), it is also possible that the terminal block main body is a resin member formed by die molding with at least a part of the wiring for the temperature sensor as an insert part.

[0015] Thereby, passage of liquid along the wiring for the temperature sensor can be suppressed.

[0016] (3) In the terminal block module of (1) or (2), it is also possible that the terminal block main body supports the internal connector for the temperature sensor at a position facing the connector of the temperature sensor installed in the device housing.

[0017] Thereby, when the temperature sensor or the terminal block module is installed in the device housing, it is possible to easily connect the connector of the temperature sensor to the internal connector for the temperature sensor.

[0018] (4) In the terminal block module of any one of (1) to (3), it is also possible that the connection direction of the connector of the temperature sensor with respect to the internal connector for the temperature sensor is set along the rotation axis direction of the rotating electric machine.

[0019] Most of the various components of the rotating electric machine are assembled along the rotation axis direction of the rotating electric machine. If the connection direction of the temperature sensor with respect to the internal connector for the temperature sensor is along the rotation axis direction, their connection work can be easily performed.

[0020] (5) In the terminal block module of any one of (1) to (4), it is also possible that an external connector is further provided, the external connector having an outer terminal for the temperature sensor connected to the wiring for the temperature sensor and being supported by the terminal block main body so as to be connectable to a connector from outside the device housing. Thus, by connecting the connector from outside the device housing to the external connector, it is possible to easily connect the device of the rotating electric machine to the wiring for the temperature sensor.

[0021] (6) In the terminal block module of (5), it is also possible that the internal connector for the temperature sensor has an internal connector housing, the external connector has an external connector housing, the inner terminal for the temperature sensor, the outer terminal for the temperature sensor, and the wiring for the temperature sensor are integrally formed as a metal wiring member, and the terminal block body, the internal connector housing, and the external connector housing are parts integrally formed by resin through a mold, such that the inner terminal for the temperature sensor is located within the internal connector housing, the outer terminal for the temperature sensor is located within the external connector housing, and the wiring for the temperature sensor is disposed as an insert member in the terminal block body.

[0022] Thus, one end and the other end of the metal wiring member can be utilized as the terminals of the connector, and the terminal block body, the internal connector housing, and the external connector housing can be integrally formed by resin through a mold, thereby enabling easy manufacture of the terminal block module having each connector. Since the middle portion of the wiring for the sensor is disposed within the terminal block body, the water tightness is also excellent.

[0023] (7) In the terminal block module of (5) or (6), it is also possible that the connection direction of the outer connector with respect to the external connector is set to be along the direction from the outer peripheral side of the equipment housing toward the inner peripheral side.

[0024] Thus, it is easy to make the connection direction of the outer bus bar terminal with respect to the connection member and the connection direction of the outer connector with respect to the external connector coincide, and their connection operation can be easily performed.

[0025] (8) In the terminal block module of any one of (1) to (7), it is also possible that the terminal block body has an inner opening and an outer opening, the inner opening receives the inner bus bar terminal along the rotation axis direction of the rotary electric machine, the outer opening receives the outer bus bar terminal along the direction from the outer peripheral side of the equipment housing toward the inner peripheral side, and the connection member presses the inner bus bar terminal received through the inner opening against the outer bus bar terminal received through the outer opening. In this case, when the inner bus bar terminal is inserted into the inner opening along the rotation axis direction and the outer bus bar terminal is inserted into the outer opening from the outer peripheral side of the equipment housing toward the inner peripheral side, the inner bus bar terminal and the outer bus bar terminal can be easily connected.

[0026] (9) In the terminal block module of any one of (1) to (8), it is also possible that it further includes: an internal connector for the speed sensor, having an inner terminal for the speed sensor, and being supported by the terminal block body so as to be located within the equipment housing; and a wiring for the speed sensor, at least a part of which is held within the terminal block body and connects the inner terminal for the speed sensor to a circuit outside the equipment housing.

[0027] Thus, if the terminal block body that holds the connection member is fixed to the equipment housing, the internal connector for the speed sensor is arranged inside the equipment housing. If the speed sensor is connected to the internal connector for the speed sensor, the speed sensor is connected via the wiring for the speed sensor to the wiring outside the rotating electric machine. Therefore, it is possible to easily connect the wiring connected to the speed sensor installed inside the rotating electric machine to the wiring outside the rotating electric machine.

[0028] (10) In the terminal block module of (9), it is also possible that the terminal block body supports the internal connector for the temperature sensor and the internal connector for the speed sensor so as to face the same side in the rotating shaft direction of the rotating electric machine.

[0029] Thus, when the temperature sensor and the speed sensor are on the same side with respect to the terminal block module, it is easy to connect the temperature sensor to the internal connector for the temperature sensor and to connect the speed sensor to the internal connector for the speed sensor.

[0030] (11) In the terminal block module of (9) or (10), it is also possible that an external connector is further provided, and the external connector has an outer terminal for the temperature sensor connected to the wiring for the temperature sensor and an outer terminal for the speed sensor connected to the wiring for the speed sensor, and is supported by the terminal block body so as to be connectable to a connector from outside the equipment housing.

[0031] In this way, by connecting the connector from outside the equipment housing to the external connector, it is possible to easily connect the equipment outside the rotating electric machine to the temperature sensor and the speed sensor.

[0032] In addition, the wiring unit for a rotating electric machine according to the present invention is as follows.

[0033] (12) A wiring unit for a rotating electric machine includes a terminal block module according to any one of (1) to (11) and a coil end module, and the coil end module has: a coil end lead-out terminal connected to the coil wire of the rotating electric machine inside the equipment housing; a coil end holding portion that holds the coil end lead-out terminal; the temperature sensor thermally coupled to the coil wire; and a temperature sensor side connector connected to the temperature sensor, and the coil end holding portion holds the temperature sensor side connector at a position where it can be connected to the internal connector for the temperature sensor.

[0034] According to the present invention, the coil end lead-out terminal and the temperature sensor of the coil end module can be connected to external wiring by using the terminal block module.

[0035] In addition, the coil end module according to the present invention is as follows.

[0036] (13) A coil end module is installed inside the equipment housing of a rotating electric machine. The coil end module includes: a coil end lead-out terminal that is connected to the coil wire of the rotating electric machine inside the equipment housing; a coil end holding portion that holds the coil end lead-out terminal; a temperature sensor that is thermally coupled to the coil wire; and a temperature sensor side connector that is connected to the temperature sensor, and the coil end holding portion holds the temperature sensor side connector.

[0037] According to the present invention, since the coil end holding portion holds the temperature sensor side connector, it is easy to connect the temperature sensor to other wirings using the temperature sensor side connector.

[0038] [Details of Embodiments of the Present Invention] Hereinafter, specific examples of the terminal block module, the wiring unit for a rotating electric machine, and the coil end module of the present invention will be described with reference to the drawings. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0039] [Embodiment] Hereinafter, the terminal block module, the wiring unit for a rotating electric machine, and the coil end module of the embodiment will be described. In the present embodiment, an example in which the terminal block module, the wiring unit for a rotating electric machine, and the coil end module are installed in a mechatronic unit will be described.

[0040] [Overall Structure] For ease of explanation, the overall structure of the mechatronic unit will be described. Figure 1 is a perspective view showing the mechatronic unit 20. Figure 2 and Figure 3 is an exploded perspective view showing the mechatronic unit 20.

[0041] The mechatronic unit 20 is a unit in which a rotating electric machine 40 and a control device 30 for controlling the rotating electric machine 40 are integrated.

[0042] The rotating electric machine 40 is a rotating electric machine including an equipment housing 41, an armature 46, and an excitation 49. The rotating electric machine 40 can be either a motor or a generator.

[0043] The equipment housing 41 includes a bottomed cylindrical housing main body 42 and a cover portion 43. The armature 46 as a stator is housed inside the housing main body 42. The excitation 49 is arranged as a rotor inside the armature 46. Due to the magnetic field generated by the armature 46, the excitation 49 rotates, or due to the rotation of the excitation 49, the armature 46 generates an electromotive force.

[0044] The armature 46 includes a coil wire 46a. The coil wire 46a is a linear conductive member made of copper wire or the like. The coil wire 46a can also be wound around the armature core.

[0045] The control device 30 is, for example, an inverter device that drives and controls the rotating electric machine 40. It is assumed that the control device 30 is integrated with the device housing 41 of the rotating electric machine 40 by means of bolt fixing or the like.

[0046] An outer bus bar terminal 38 extends from the control device 30. The coil wire 46a is connected to the outer bus bar terminal 38 via the coil end module 50 and the terminal block module 70.

[0047] The coil end module 50 is located on the opening side of the housing main body 42 in the armature 46. The coil end module 50 has a coil end lead-out terminal 58 that is connected to the coil wire 46a inside the device housing 41. The coil end lead-out terminal 58 extends from the armature 46 toward the opening side of the housing main body 42. The coil end lead-out terminal 58 extends toward the terminal block module 70 side. The coil end lead-out terminal 58 is an example of an inner bus bar terminal inside the device housing 41.

[0048] The coil end module 50 may also have a structure that connects the ends of the plurality of coil wires 46a of the armature 46 to each other.

[0049] The terminal block module 70 is located beside the coil end module 50 in the direction of the rotation axis X of the rotating electric machine 40. The terminal block module 70 is mounted on the inside of the cover portion 43. An opening 43h is formed in a portion of the cover portion 43 on the control device 30 side with respect to the terminal block module 70. When the control device 30 is mounted on the rotating electric machine 40, the outer bus bar terminal 38 extends through the opening 43h toward the terminal block module 70.

[0050] The coil end lead-out terminal 58 and the outer bus bar terminal 38 are electrically connected via the terminal block module 70.

[0051] In the present embodiment, it is assumed that the rotating electric machine 40 is a rotating electric machine that can be used as a three-phase AC motor. Therefore, the rotating electric machine 40 has three coil end lead-out terminals 58, and the control device 30 has three outer bus bar terminals 38. The three coil end lead-out terminals 58 are respectively electrically connected to the three outer bus bar terminals 38 via the terminal block module 70.

[0052] In the following description, in the direction along the rotation axis X of the rotating electric machine 40, the cover portion 43 side may sometimes be referred to as the front side, and the opposite side may be referred to as the rear side. Further, in the direction orthogonal to the rotation axis X, the rotating electric machine 40 side may sometimes be referred to as the lower side, and the control device 30 side may be referred to as the lower side. Furthermore, the left-right direction may sometimes be referred to based on this up-down and front-back.

[0053] In addition, the rotary electric machine 40 is provided with a speed sensor 100. The speed sensor 100 is, for example, a sensor that detects the rotational speed of the excitation 49 (which is the rotor) by detecting the rotation angle of the excitation 49. The speed sensor 100 may also be a sensor known as a resolver.

[0054] In addition, the rotary electric machine 40 is provided with a temperature sensor 110. The temperature sensor 110 is a sensor that detects the temperature inside the rotary electric machine 40, for example, the temperature of the coil wire 46a.

[0055] The detection signal of the speed sensor 100 and the detection signal of the temperature sensor 110 are provided to the control device 30 described above. Thereby, the control device 30 can control the rotary electric machine 40 based on the detection signal of the speed sensor 100 and the detection signal of the temperature sensor 110.

[0056] The terminal block module 70 described above has an internal connector 74 for the speed sensor that is connected to the speed sensor 100 inside the device housing 41. In addition, the terminal block module 70 has a wiring for transmitting the detection signal of the speed sensor 100 to the outside. Therefore, the detection signal of the speed sensor 100 inside the device housing 41 can be easily output to the outside via the internal connector 74 for the speed sensor and this wiring. The structure of the internal connector 74 for the speed sensor and the wiring therefor may be configured separately from the terminal block module, or may be omitted.

[0057] In addition, the terminal block module 70 described above has an internal connector 76 for the temperature sensor that is connected to the temperature sensor 110 inside the device housing 41. In addition, the terminal block module 70 has a wiring for transmitting the detection signal of the temperature sensor 110 to the outside. Therefore, the detection signal of the temperature sensor 110 inside the device housing 41 can be easily output to the outside via the internal connector 76 for the temperature sensor and this wiring.

[0058] Hereinafter, the structure of each part will be described.

[0059] <Coil end module> Figure 4 is a perspective view showing the coil end module 50. In Figure 4 a part of the coil wire 46a extending from the armature 46 is shown. Figure 5 is a perspective view showing the part of the coil end module 50 where the temperature sensor 110 and the temperature sensor side connector 112 are assembled.

[0060] As Figures 2 to 5 shown, the coil end module 50 has a coil end lead-out terminal 58 and a coil end holding portion 52.

[0061] The coil end lead terminal 58 is connected to the coil wire 46a. The coil end holding portion 52 supports the coil end lead terminal 58 in a cantilever shape along the direction of the rotation axis X of the rotating electric machine 40.

[0062] More specifically, the coil end holding portion 52 is formed of an insulating member such as resin. Insertion holes 52h into which a plurality of coil wires 46a extending from the armature 46 can be inserted are formed in the coil end holding portion 52. Illustrated in Figure 4 is a part of the ends of the plurality of coil wires 46a.

[0063] The coil end holding portion 52 is formed in an arc shape so as to be able to be disposed on a part of the circumferential direction of the end face on the cover portion 43 side in the armature 46. The coil end holding portion 52 holds the relay bus bar 53. The relay bus bar 53 is a conductive member formed of a metal plate such as copper. The relay bus bar 53 has a connection end 53a that can be adjacently disposed to the coil wire 46a inserted into the insertion hole 52h. The end of the coil wire 46a inserted into the insertion hole 52h is electrically connected to the connection end 53a. For example, the coil wire 46a may also be joined to the connection end 53a. The joining may be Tig welding, laser welding, resistance welding, ultrasonic joining, soldering, or rivet joining.

[0064] The relay bus bar 53 has an intermediate connection portion that connects the plurality of connection ends 53a in a predetermined combination. Thus, the plurality of coil wires 46a connected to the connection ends 53a are electrically connected in a predetermined combination.

[0065] The coil end lead terminal 58 extends from the surface of the cover portion 43 in the coil end holding portion 52. As described above, three coil end lead terminals 58 extend from the coil end holding portion 52. The three coil end lead terminals 58 are positioned at intervals along an arc with the rotation axis X as the center of curvature. Each coil end lead terminal 58 is along the rotation axis X.

[0066] The coil end lead terminal 58 may also be connected to the connection end 53a connected to any one of the coil wires 46a via an intermediate connection portion. For example, the coil end lead terminal 58 may also be a metal plate portion integrally formed with the relay bus bar 53. The coil end lead terminal 58 may also be directly connected to the coil wire 46a.

[0067] The coil end lead terminal 58 is formed in an elongated plate shape. One main surface of the coil end lead terminal 58 faces the inside of the equipment housing 41, and the other main surface faces the outside of the equipment housing 41. Therefore, the coil end lead terminal 58 can be deformed in such a way that the tip end portion is displaced in the inner and outer circumferential directions of the equipment housing 41 with the base end portion cantilever-supported by the coil end holding portion 52 as the center.

[0068] In addition, the coil end module 50 has a temperature sensor 110 and a temperature sensor side connector 112.

[0069] The temperature sensor 110 is a temperature sensor thermally coupled to the above-mentioned coil wire 46a. The temperature sensor 110 being thermally coupled to the coil wire 46a means being in a state where the temperature change of the coil wire 46a can be detected by the temperature sensor 110. For example, the temperature sensor 110 can either be in direct contact with the coil wire 46a or in contact via a heat-conducting member such as copper. That is, the heat-conductive member that is the temperature measurement object of the temperature sensor 110 can either be the coil wire 46a itself, or the relay bus bar 53 joined to the above-mentioned coil wire 46a, or a heat-conductive relay member separately connected to the coil wire 46a from the relay bus bar 53, or a part where the coil wire 46a branches and leads out midway.

[0070] The temperature sensor 110 can also be, for example, a sensor in which a thermistor element is covered with resin. The maintenance of the contact state between the temperature sensor 110 and the coil wire 46a or the heat-conductive member can also be carried out through the following structure, for example.

[0071] The temperature sensor 110 can be held in a fixed position by the coil-end holding portion 52, and the heat-conductive member can be inserted into the coil-end holding portion 52 and held in a state of being in contact with the temperature sensor 110. In addition, the temperature sensor 110 and the heat-conductive member can be held in a state of being in contact with each other in the coil-end holding portion 52, and the heat-conductive member can be joined to the coil wire 46a by welding or the like. The heat-conductive member can also have a riveting piece, and the riveting piece is riveted to the temperature sensor 110.

[0072] As an example of the wiring, a wire 114 extends from the temperature sensor 110. A temperature-sensor-side connector 112 is connected to the end of the wire 114. The temperature-sensor-side connector 112 is connected to the temperature sensor 110 via the wire 114.

[0073] The coil-end holding portion 52 holds the temperature-sensor-side connector 112 in a position where it can be connected to the temperature-sensor internal connector 76 on the terminal block module 70 side.

[0074] Here, a connector holding portion 54 protrudes at a position near one end of the coil end holding portion 52. More specifically, the connector holding portion 54 protrudes from the surface of the coil end holding portion 52 facing the terminal block module 70 and at a position avoiding the coil wire 46a and the connection end 53a. The connector holding portion 54 protrudes along the rotation axis X. An inner connector receiving portion 55 is formed at the top end portion of the connector holding portion 54. The inner connector receiving portion 55 is formed in a box shape that opens on the side of the terminal block module 70. The inner peripheral surface of the inner connector receiving portion 55 is larger than the outer peripheral surface of the temperature sensor side connector 112, and the temperature sensor side connector 112 can move in a direction orthogonal to the rotation axis X within the inner connector receiving portion 55. A wire insertion groove 55g is formed from the peripheral wall to the bottom surface of the inner connector receiving portion 55. The wire 114 extending from the temperature sensor side connector 112 passes through the wire insertion groove 55g and is led toward the temperature sensor 110.

[0075] The temperature sensor side connector 112 is held by housing the base end portion of the temperature sensor side connector 112 in the inner connector receiving portion 55. In this state, the temperature sensor side connector 112 can move in a direction orthogonal to the rotation axis X within the range restricted by the inner surface of the inner connector receiving portion 55. In addition, the movement toward the armature 46 side in the direction along the rotation axis X is restricted by the bottom surface of the inner connector receiving portion 55.

[0076] The temperature sensor side connector 112 faces the terminal block module 70, and the temperature sensor side connector 112 and the temperature sensor internal connector 76 on the side of the terminal block module 70 can be connected by approaching and moving along the rotation axis X through the coil end module 50 and the terminal block module 70. At this time, according to the position error between the two connectors 112 and 76, the temperature sensor side connector 112 can move in a direction orthogonal to the rotation axis X.

[0077] A wire support portion 54P capable of supporting the wire 114 may be provided outside the inner connector receiving portion 55 in the connector holding portion 54. By supporting the wire 114 with the wire support portion 54P, it is possible to prevent the temperature sensor side connector 112 from easily falling off the inner connector receiving portion 55.

[0078] <Terminal block module> Figure 6 and Figure 7 is a perspective view showing the terminal block module 70. In Figure 6 and Figure 7 the coil end lead-out terminal 58 and the outer bus bar terminal 38 are indicated by a two-dot chain line. As Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the terminal block module 70 is a component fixed to the device housing 41. The terminal block module 70 has a connecting component 80 and a terminal block body 72.

[0079] The connecting component 80 is a component for electrically connecting the coil terminal lead-out terminal 58, which is an inner bus bar terminal, and the outer bus bar terminal 38 outside the device housing 41. The connecting component 80 may not necessarily have the main function of electrically connecting the coil terminal lead-out terminal 58 and the outer bus bar terminal 38, but rather play an auxiliary role. That is, for example, the connecting component 80 does not have to be a conductive path between the coil terminal lead-out terminal 58 and the outer bus bar terminal 38.

[0080] In the present embodiment, the connecting component 80 acts to hold the two terminals 58 and 38 in a more reliably electrically connected state by applying a force to the coil terminal lead-out terminal 58 towards the outer bus bar terminal 38.

[0081] Figure 8 It is a perspective view showing the connecting component 80. Figure 9 It is an exploded perspective view showing the connecting component 80. As Figures 6 to 9 shown, the connecting component 80 includes a support member 82, a biasing member 86, and a pressing piece 88.

[0082] The support member 82 has a bottom 83, on which the biasing member 86 is supported. For example, the support member 82 is formed by stamping a metal plate or the like. The support member 82 includes a bottom 83 and a pair of side plates 84. The bottom 83 is formed in a square plate shape. The pair of side plates 84 extend from both side portions of the bottom 83 towards one main surface side of the bottom 83. Positioning pieces 83a protrude from the front and rear edges of the bottom 83. The biasing member 86 on the bottom 83 is positioned on the bottom 83 in a state of being located between the pair of side plates 84 and the front and rear positioning pieces 83a.

[0083] A guide groove 84g extending in the extending direction of the side plate 84 is formed at the top end of the side plate 84. An anti-detachment piece 84a protrudes from the upper end of the rear side edge in the bottom 83. The movement direction and movement range of the pressing piece 88 are restricted by the guide groove 84g and the anti-detachment piece 84a.

[0084] The biasing member 86 is an elastic member such as a helical spring. The biasing member 86 may also be a leaf spring, a disc spring, rubber, etc. The biasing member 86 is supported on the bottom 83. The upper end portion of the biasing member 86 is located at a position farther from the bottom 83 than the anti-detachment piece 84a.

[0085] The pressing piece 88 is supported by the support member 82 so as to be movable in the approaching or separating direction with respect to the bottom 83. The pressing piece 88 is formed by stamping a metal plate or the like, for example.

[0086] In the present embodiment, the pressing piece 88 has a pressing plate portion 88a, a guiding portion 88g, and a hanging plate portion 88b.

[0087] The pressing plate portion 88a is a flat plate shape, and in this case, it is a square plate shape. The pressing plate portion 88a is located on the side opposite to the bottom 83 with respect to the biasing member 86. That is, the pressing plate portion 88a is located on the biasing member 86. The pressing plate portion 88a is orthogonal to the biasing direction of the biasing member 86, that is, parallel to the bottom 83. The biasing member 86 is interposed between the pressing plate portion 88a and the bottom 83 in a compressed state. When the pressing plate portion 88a approaches or separates from the bottom 83 with the expansion and contraction of the biasing member 86, the pressing plate portion 88a is positioned in the left - right direction by contacting the inner surfaces of the pair of side plates 84.

[0088] In addition, protrusions 88ap protrude from both sides of the pressing plate portion 88a. The protrusions 88ap move along the above - mentioned guiding groove 84g. When the pressing plate portion 88a moves, on the left and right sides of the pressing plate portion 88a respectively, the protrusions 88ap contact the two side edges of the guiding groove 84g, thereby positioning the pressing plate portion 88a in the front - rear direction.

[0089] The guiding portion 88g extends from the rear side of the peripheral edge of the pressing plate portion 88a, that is, the edge on the side of the coil - end module 50. The guiding portion 88g extends in such a way that it gradually approaches the bottom 83 side in a direction away from the pressing plate portion 88a. In the present embodiment, the guiding portion 88g forms a partial cylindrical shape from the rear edge of the pressing plate portion 88a and extends rearward and downward.

[0090] The hanging plate portion 88b extends from the top - end edge of the guiding portion 88g toward the bottom 83 side along the biasing direction of the biasing member 86. The hanging plate portion 88b covers the biasing member 86 from the side of the coil - end module 50.

[0091] Protrusions 88bp protrude from the upper parts of both side edges of the hanging plate portion 88b. The protrusions 88bp move up and down along the rear edge of the side plate 84 and contact the anti - detachment piece 84a from the bottom 83 side. By the protrusions 88bp contacting the anti - detachment piece 84a, the movement of the pressing piece 88 in the direction away from the bottom 83 is restricted.

[0092] By the movement of the pressing piece 88 being restricted by the protrusions 88ap, 88bp and the guiding groove 84g and the anti - detachment piece 84a, the supporting member 82 supports the pressing piece 88 so that it can reciprocate between a standby position and a proximity position closer to the bottom 83 than the standby position. In the present embodiment, the standby position is the position where the protrusion 88bp contacts the anti - detachment piece 84a from the bottom 83 side. The standby position is the position where the protrusion 88ap contacts the edge on the bottom 83 side in the guiding groove 84g.

[0093] The terminal block main body 72 is formed of resin or the like and is fixed to the lid portion 43 of the equipment housing 41 in a state of holding the above-described connection member 80.

[0094] More specifically, the terminal block main body 72 is formed in an elongated shape. A receiving recess 73 for receiving the connection member 80 is formed in the terminal block main body 72. In the present embodiment, in order to hold three connection members 80, the terminal block main body 72 is formed with three receiving recesses 73 arranged along the extending direction of the terminal block main body 72. A threaded fastening portion 71 serving as a mounting portion is integrally formed on the terminal block main body 72. The terminal block main body 72 is fixed to the lid portion 43 by being threadedly fastened via the threaded fastening portion 71.

[0095] The terminal block main body 72 has an inner opening 73h1 and an outer opening 73h2. Each receiving recess 73 opens at the inner opening 73h1 and the outer opening 73h2.

[0096] The inner opening 73h1 is an opening for receiving the coil end lead terminal 58 as an inner bus bar terminal along the rotation axis X. That is, the inner opening 73h1 opens on the extension line in front of the coil end lead terminal 58.

[0097] The outer opening 73h2 is an opening for receiving the outer bus bar terminal 38 along the direction from the outer peripheral side to the inner peripheral side of the equipment housing 41. That is, the outer opening 73h2 opens on the extension line of the outer bus bar terminal 38 extending from the control device 30 mounted on the rotating electric machine 40.

[0098] As will be described later, the coil end module 50 is mounted on the end portion of the armature 46 inside the housing main body 42. In addition, the terminal block module 70 is mounted on the lid portion 43. And when the lid portion 43 is mounted on the housing main body 42, as Figure 10 and Figure 11 shown, the coil end lead terminal 58 is guided to the pressing piece 88 through the inner opening 73h1. At this time, when the coil end lead terminal 58 is located below the pressing plate portion 88a, the top end portion of the coil end lead terminal 58 comes into contact with the guiding portion 88g. Since the coil end lead terminal 58 is supported in a cantilever shape, the coil end lead terminal 58 can be inclined so that the top end portion of the coil end lead terminal 58 is displaced upward. Thereby, the top end portion of the coil end lead terminal 58 can be guided by the guiding portion 88g and moved onto the pressing plate portion 88a.

[0099] Thereby, the coil end lead terminal 58 comes into a state opposite to the bottom portion 83 with respect to the biasing member 86.

[0100] When the control device 30 is installed on the rotating electric machine 40, the outer bus bar terminal 38 moves to the connecting member 80 through the outer opening 73h2. The outer bus bar terminal 38 is disposed on the opposite side of the urging member 86 with respect to the coil end lead-out terminal 58.

[0101] In a state where the control device 30 is installed on the rotating electric machine 40, the lower end position of the outer bus bar terminal 38 is set to a position where the urging member 86 can be compressed in consideration of the thickness of the coil end lead-out terminal 58 and the thickness of the pressing plate portion 88a. For example, it is set such that, in a state where the control device 30 is installed on the rotating electric machine 40, a gap smaller than the thickness of the coil end lead-out terminal 58 is formed between the lower end position of the outer bus bar terminal 38 and the pressing plate portion 88a.

[0102] In a state where the control device 30 is installed on the rotating electric machine 40, the lower end of the outer bus bar terminal 38 presses the urging member 86 downward via the coil end lead-out terminal 58 and the pressing plate portion 88a, causing the urging member 86 to be compressed. At this time, since the coil end lead-out terminal 58 is supported in a cantilever shape, it can tilt about the base end when pressed by the outer bus bar terminal 38.

[0103] In this state, due to the urging force of the urging member 86 to return to its original length, the pressing plate portion 88a tends to move upward. The coil end lead-out terminal 58 is pressed against the outer bus bar terminal 38 by this urging force. That is, in the completed state of the mechatronic unit 20, the urging member 86 always urges the coil end lead-out terminal 58 toward the outer bus bar terminal 38. Therefore, the coil end lead-out terminal 58 and the outer bus bar terminal 38 are held in a more reliably electrically connected state.

[0104] In the present embodiment, as described above, an example in which the pressing plate portion 88a of the pressing piece 88 is interposed between the urging member 86 and the coil end lead-out terminal 58 has been described. The pressing piece 88 may be omitted, and the urging member 86 may directly press the coil end lead-out terminal 58 toward the outer bus bar terminal 38.

[0105] As described above, the wiring unit 28 for a rotating electric machine is composed of the terminal block module 70 and the coil end module 50, and the wiring unit 28 for a rotating electric machine connects the coil wire 46a to the outer bus bar terminal 38 inserted from outside the equipment housing 41.

[0106] <Structure related to sensor wiring> The terminal block module 70 has a structure for leading out the speed sensor 100 inside the equipment housing 41 to the outside.

[0107] That is, the terminal block module 70 includes an internal connector 74 for a speed sensor and a wiring 60 for a speed sensor.

[0108] An extension portion 72E is integrally formed at one end of the terminal block body 72 by a mold. An internal connector 74 for a speed sensor is formed in the extension portion 72E.

[0109] The internal connector 74 for a speed sensor has an inner terminal 75 for a speed sensor, and is supported by the terminal block body 72 so as to be located within the device housing 41. The internal connector 74 for a speed sensor is a part configured to be able to connect to the speed sensor side connector 106 of the speed sensor 100.

[0110] More specifically, the internal connector 74 for a speed sensor has an internal connector housing 74a and an inner terminal 75 for a speed sensor. The internal connector housing 74a has a recess into which the speed sensor side connector 106 can be inserted. The inner terminal 75 for a speed sensor projects from the bottom of the recess of the internal connector housing 74a. By inserting and connecting the speed sensor side connector 106 into the internal connector housing 74a, the inner terminal 75 for a speed sensor is connected to the terminal on the speed sensor side connector 106 side.

[0111] The terminal block body 72 supports the internal connector 74 for a speed sensor at a position facing the speed sensor side connector 106 of the speed sensor 100 housed within the device housing 41. In the present embodiment, the connection direction of the speed sensor side connector 106 with respect to the internal connector 74 for a speed sensor is set to be along the rotation axis X.

[0112] Here, the speed sensor 100 has an annular main body portion 102, a connector support portion 104 that projects outward from a part of the circumferential direction of the annular main body portion 102, and a speed sensor side connector 106 supported at the tip of the connector support portion 104 (see Figure 13 ). In the annular main body portion 102, for example, the portion where the coil wire is wound is arranged in a ring shape. As the excitation 49 rotates, the current excited by the coil wire is output via the speed sensor side connector 106. In addition, the speed sensor 100 does not have to be the above structure, and may also be a speed sensor using an optical sensor, a magnetic sensor, or the like.

[0113] The annular main body portion 102 has a threaded fastening portion 103 as a mounting portion, and the annular main body portion 102 is mounted to the cover portion 43 using the threaded fastening portion 103. The speed sensor side connector 106 is located outside the annular main body portion 102. Here, the internal connector 74 for a speed sensor has a shape that is longer in the tangential direction of a circle centered on the rotation axis X on a plane orthogonal to the rotation axis X.

[0114] Both the terminal block module 70 and the speed sensor 100 are mounted on the cover portion 43. The position of the internal connector 74 for the speed sensor in the terminal block module 70 is a position opposed to the speed sensor side connector 106 in the mounted state on the cover portion 43. Further, the internal connector 74 for the speed sensor faces rearward along the rotation axis X, and the speed sensor side connector 106 faces forward along the rotation axis X. Therefore, in the state where the terminal block module 70 and the speed sensor 100 are mounted on the cover portion 43, the internal connector 74 for the speed sensor and the speed sensor side connector 106 face each other and are connected to each other along the rotation axis X.

[0115] At least a part of the wiring 60 for the speed sensor is held inside the terminal block body 72, and the wiring 60 for the speed sensor connects the inner terminal 75 for the speed sensor to the terminal of the outer connector which is a circuit from outside the equipment housing 41. Further, a plurality of wirings 60 for the speed sensor are provided corresponding to the plurality of inner terminals 75 for the speed sensor (only a part is illustrated in Figure 6 ).

[0116] The wiring 60 for the speed sensor may be a portion formed by stamping a metal plate such as copper into a linear shape, a metal wire, or a wire in which a metal wire is coated with resin. In the present embodiment, it is assumed that the wiring 60 for the speed sensor is a portion formed by stamping a metal plate such as copper into a linear shape.

[0117] Further, it is assumed that the terminal block body 72 is a resin member formed by die molding with at least a part of the wiring 60 for the speed sensor as an insert portion. The terminal block body 72 may also be a member having a through hole through which the wiring 60 for the speed sensor can pass, and is configured to fill the gap between the wiring and the through hole with a filling material or the like in a state where the wiring 60 for the speed sensor is disposed in the through hole.

[0118] Further, the terminal block module 70 has an external connector 78, and the external connector 78 has an outer terminal 79t1 for the speed sensor. The outer terminal 79t1 for the speed sensor is connected to the wiring 60 for the speed sensor. A plurality of outer terminals 79t1 for the speed sensor are provided corresponding to the number of the plurality of inner terminals 75 for the speed sensor. The external connector 78 is a portion supported by the terminal block body 72 so as to be able to connect to the outer connector 39 from outside the equipment housing 41.

[0119] More specifically, the external connector 78 has an external connector housing 78a and an outer terminal 79t1 for a speed sensor. The external connector housing 78a is a part integrally formed with the extension 72E of the terminal block body 72 by a mold, and has a recess into which the outer connector 39 can be inserted. The outer terminal 79t1 for a speed sensor projects from the bottom of the recess of the external connector housing 78a. The outer connector 39 is inserted and connected into the external connector housing 78a, so that the outer terminal 79t1 for a speed sensor is connected to the terminal on the side of the outer connector 39.

[0120] The terminal block body 72 supports the external connector 78 at a position facing the outer connector 39 on the side of the control device 30 mounted on the equipment housing 41. In the present embodiment, the control device 30 supports the outer connector 39 at a position beside the outer bus bar terminal 38. The outer connector 39 is supported toward the side of the rotary electric machine 40, that is, downward, and the connection direction of the outer connector 39 with respect to the external connector 78 is set to a direction orthogonal to the rotation axis X, which is the vertical direction here. That is, the connection direction of the outer connector 39 with respect to the external connector 78 is set to a direction along the direction from the outer peripheral side to the inner peripheral side of the equipment housing 41.

[0121] In a state where the rotary electric machine 40 is assembled, the control device 30 is mounted on the rotary electric machine 40. At this time, the outer connector 39 is inserted into the external connector 78 from above through the opening 43h of the cover portion 43. In a state where the control device 30 is mounted on the rotary electric machine 40, the outer connector 39 and the external connector 78 face each other and are connected to each other.

[0122] As described above, the speed sensor side connector 106 of the speed sensor 100 is connected to the internal connector 74 for a speed sensor, and the outer connector 39 is connected to the external connector 78. The inner terminal 75 for a speed sensor of the internal connector 74 for a speed sensor and the outer terminal 79t1 for a speed sensor of the external connector 78 are connected via the wiring 60 for a speed sensor. The above-mentioned internal connector 74 for a speed sensor, external connector 78, and wiring 60 for a speed sensor are integrally installed in the terminal block module 70. Therefore, the speed sensor 100 is connected to the control device 30 via the terminal block module 70.

[0123] The inner terminal 75 for a speed sensor, the outer terminal 79t1 for a speed sensor, and the wiring 60 for a speed sensor may also be integrally formed as a metal wiring member. For example, by stamping a metal plate such as copper, a metal wiring member in which the inner terminal 75 for a speed sensor, the wiring 60 for a speed sensor, and the outer terminal 79t1 for a speed sensor are connected in sequence may be formed.

[0124] As described above, the terminal block body 72, the inner connector housing 74a, and the outer connector housing 78a may also be components integrally formed from resin by a mold. In this case, it is also possible to form the inner terminal 75 for the speed sensor within the inner connector housing 74a, the outer terminal 79t1 for the speed sensor within the outer connector housing 78a, and the wiring 60 for the speed sensor as an insert part buried in the terminal block body 72 (here, the extension part 72E). Thus, the inner connector 74 and the outer connector 78 for the speed sensor can be easily integrally formed in the terminal block module 70. In addition, the terminal block body 72 may be formed by multiple moldings such as two-color molding or double molding.

[0125] In addition, the terminal block module 70 is provided with a structure for leading out the temperature sensor 110 within the equipment housing 41 to the outside.

[0126] That is, the terminal block module 70 includes an inner connector 76 for the temperature sensor and a wiring 62 for the temperature sensor.

[0127] An inner connector 76 for the temperature sensor is formed at the extension part 72E at one end of the terminal block body 72.

[0128] The inner connector 76 for the temperature sensor has an inner terminal 77 for the temperature sensor, and is supported by the terminal block body 72 so as to be located within the equipment housing 41. The inner connector 76 for the temperature sensor is a part configured to be able to connect to the temperature sensor side connector 112 of the temperature sensor 110.

[0129] More specifically, the inner connector 76 for the temperature sensor has an inner connector housing 76a and an inner terminal 77 for the temperature sensor. The inner connector housing 76a has a recess into which the temperature sensor side connector 112 can be inserted. The inner terminal 77 for the temperature sensor projects from the bottom of the recess of the inner connector housing 76a. By inserting and connecting the temperature sensor side connector 112 into the inner connector housing 76a, the inner terminal 77 for the temperature sensor is connected to the terminal on the temperature sensor side connector 112 side.

[0130] The terminal block body 72 supports the inner connector 76 for the temperature sensor at a position facing the temperature sensor side connector 112 of the temperature sensor 110 installed within the equipment housing 41. In the present embodiment, the connection direction of the temperature sensor side connector 112 with respect to the inner connector 76 for the temperature sensor is set to be along the direction of the rotation axis X.

[0131] As described above, the temperature sensor 110 is held by the coil end module 50, and the temperature sensor side connector 112 is also held by the coil end module 50. The temperature sensor side connector 112 faces the front side along the rotation axis X. The position where the temperature sensor side connector 112 is supported is the position on the outer peripheral side of the above-described speed sensor side connector 106. The internal connector 76 for the temperature sensor faces the rear side along the rotation axis X, and thus faces the temperature sensor side connector 112.

[0132] Moreover, in a state where the coil end module 50 is mounted on the armature 46 within the housing main body 42 and the terminal block module 70 is mounted on the cover portion 43, when the cover portion 43 is mounted on the housing main body 42, the temperature sensor side connector 112 and the internal connector 76 for the temperature sensor move closer to each other, and the two connectors 76, 112 are connected. At this time, the temperature sensor side connector 112 is supported by the connector holding portion 54 so as to be movable. Therefore, even if a position error occurs between the two connectors 76, 112, the temperature sensor side connector 112 can be displaced in the vertical or horizontal direction in accordance with the position of the internal connector 76 for the temperature sensor.

[0133] At least a part of the wiring 62 for the temperature sensor is held within the terminal block main body 72, and the wiring 62 for the temperature sensor connects the above-described inner terminals 77 for the temperature sensor to the wiring on the outer connector side which is a circuit from outside the equipment housing 41. In addition, a plurality of wirings 62 for the temperature sensor are provided corresponding to the plurality of inner terminals 77 for the temperature sensor respectively.

[0134] The wiring 62 for the temperature sensor may be a portion obtained by punching a metal plate such as copper into a linear shape, may be a metal wire, or may be an electric wire in which a metal wire is coated with resin. In the present embodiment, it is assumed that the wiring 62 for the temperature sensor is a portion obtained by punching a metal plate such as copper into a linear shape.

[0135] In addition, it is assumed that the terminal block main body 72 is a resin member formed by die molding with at least a part of the wiring 62 for the temperature sensor as an insert part. The terminal block main body 72 may also be a member having a through hole through which the wiring 62 for the temperature sensor can pass, and is configured to fill the gap between the wiring and the through hole with a filling material or the like in a state where the wiring 62 for the temperature sensor is disposed within the through hole.

[0136] In addition, the terminal block module 70 has an external connector 78, and the external connector 78 has an outer terminal 79t2 for the temperature sensor. The outer terminal 79t2 for the temperature sensor is connected to the above-described wiring 62 for the temperature sensor. A plurality of outer terminals 79t2 for the temperature sensor are provided corresponding to the number of the plurality of inner terminals 77 for the temperature sensor. The external connector 78 is a portion supported by the terminal block main body 72 so as to be able to connect to the outer connector 39 from outside the equipment housing 41.

[0137] More specifically, the external connector 78 has an external connector housing 78a and an outer terminal 79t2 for a temperature sensor. As described above, the external connector housing 78a is a connector housing having an outer terminal 79t1 for a speed sensor. The outer terminal 79t2 for a temperature sensor projects from the bottom of the recess of the external connector housing 78a. That is, in the present embodiment, the external connector 78 has an outer terminal 79t1 for a speed sensor and an outer terminal 79t2 for a temperature sensor, and is a connector for outputting both a detection signal of speed and a detection signal of temperature.

[0138] Moreover, by inserting and connecting the outer connector 39 into the external connector housing 78a, the outer terminal 79t2 for a temperature sensor is connected to the terminal on the outer connector 39 side.

[0139] As described above, the temperature sensor side connector 112 of the temperature sensor 110 is connected to the internal connector 76 for a temperature sensor, and the outer connector 39 is connected to the external connector 78. The inner terminal 77 for a temperature sensor of the internal connector 76 for a temperature sensor and the outer terminal 79t2 for a temperature sensor of the external connector 78 are connected via the wiring 62 for a temperature sensor. The above-mentioned internal connector 76 for a temperature sensor, external connector 78, and wiring 62 for a temperature sensor are integrally housed in the terminal block module 70. Therefore, the temperature sensor 110 is connected to the control device 30 via the terminal block module 70.

[0140] The above-mentioned inner terminal 77 for a temperature sensor, outer terminal 79t2 for a temperature sensor, and wiring 62 for a temperature sensor may also be integrally formed as a metal wiring member. For example, by stamping a metal plate such as copper, a metal wiring member in which the inner terminal 77 for a temperature sensor, the wiring 62 for a temperature sensor, and the outer terminal 79t2 for a temperature sensor are connected in sequence may be formed.

[0141] As described above, the terminal block main body 72, the internal connector housing 76a, and the external connector housing 78a may also be parts integrally formed of resin by a mold. In this case, it may also be formed in a state where the inner terminal 77 for a temperature sensor is located in the internal connector housing 76a, the outer terminal 79t2 for a temperature sensor is located in the external connector housing 78a, and the wiring 62 for a temperature sensor is filled as an insert part into the terminal block main body 72 (here, the extension part 72E). Thereby, the internal connector 76 for a temperature sensor and the external connector 78 can be easily integrally formed in the terminal block module 70. In addition, the terminal block main body 72 may also be formed by multiple moldings such as two-color molding (double mold).

[0142] In addition, in that the external connector 78 has an outer terminal 79t1 for a speed sensor, the external connector 78 is an example of an external connector for a speed sensor. Further, in that the external connector 78 has an outer terminal 79t2 for a temperature sensor, the external connector 78 is an example of a connector for a temperature sensor.

[0143] In the above-described embodiment, the external connector 78 is used as a connector for outputting two detection signals of temperature and speed, but the external connector may be divided into a connector having an outer terminal for a speed sensor and a connector having an outer terminal for a temperature sensor.

[0144] <Terminal of the control device> A description will be given of a terminal 32 extending from the control device 30 toward the rotating electric machine 40 side. Figure 12 is a perspective view showing the terminal 32. The control device 30 is a device that controls the rotating electric machine 40 and has an inverter control substrate. The control device 30 has a terminal 32 that connects the inverter control substrate and the rotating electric machine 40.

[0145] The terminal 32 has a base member 33, a plurality (three in this case) of outer bus bars 38, and a signal relay unit 36.

[0146] The base member 33 has a bottom plate portion 33a and a column portion 33b protruding from the bottom plate portion 33a toward the rotating electric machine 40 side. The bottom plate portion 33a is fixed to the housing of the control device 30 by screw fastening or the like.

[0147] The outer bus bar 38 is formed of a metal plate such as a copper plate. The outer bus bar 38 has an elongated plate-shaped intermediate portion and upper and lower end portions that bend and extend from both end portions of the elongated plate-shaped intermediate portion toward one main surface side of the plate-shaped intermediate portion. The upper end portion of the outer bus bar 38 is disposed on the bottom plate portion 33a and is connected to a bus bar 130 extending from the inverter control substrate by screw fastening or the like. The plate-shaped intermediate portion of the outer bus bar 38 extends along the front side surface of the column portion 33b. The lower end portion of the outer bus bar 38 is disposed so as to overlap the lower surface of the bottom plate portion 33a.

[0148] The signal relay unit 36 includes an outer connector 39, a substrate-side connector 37, and a wiring 36W that connects the two connectors. The wiring 36W is, for example, an electric wire. The outer connector 39 is supported by a connector support portion 35 located on one side portion of the base member 33. The connector support portion 35 is located on the outside in the direction in which the plurality of column portions 33b are arranged. The lower end portion of the connector support portion 35 faces the external connector 78 in the terminal block module 70. A box-shaped connector receiving portion 35R that opens downward is formed at the lower end portion of the connector support portion 35. The inner wall surface of the connector receiving portion 35R is larger than the outer side surface of the outer connector 39. Therefore, the connector receiving portion 35R supports the outer connector 39 in a state that allows the outer connector 39 to move in the front-back and left-right directions. The wiring 36W extends from the outer connector 39 upward through the connector receiving portion 35R to the bottom plate portion 33a.

[0149] A connector receiving portion 34R having the same structure as the above-described connector receiving portion 35R is provided on the bottom plate portion 33a. The substrate-side connector 37 is supported by the connector receiving portion 34R in a state that allows it to move in the up-down and left-right directions. Further, the connector 131 on the inverter control substrate side is connected to the substrate-side connector 37.

[0150] <Manufacturing Example of Mechatronic Unit> A manufacturing example of the mechatronic unit 20 will be described.

[0151] First, the coil end module 50 is attached to the end portions of the coil wires 46a of the armature 46 (see Figure 4 ). Thereby, the coil wires 46a are connected to each other in a predetermined combination. In addition, a part of the coil wire 46a is connected to the coil end lead-out terminal 58. The armature 46 can be inserted into the housing main body 42 either after the above-described coil end module 50 is attached or before the attachment.

[0152] In addition, as Figure 13 shown, the terminal block module 70 is attached to the cover portion 43 by screw fastening or the like. In this state, the internal connector 74 for the speed sensor and the internal connector 76 for the temperature sensor of the terminal block module 70 face backward along the rotation axis X. Further, the inner opening 73h1 of the terminal block main body 72 faces backward along the rotation axis X, and the outer opening 73h2 faces the opening 43h side, that is, the outside. Furthermore, the external connector 78 faces the opening 43h side, that is, the outside.

[0153] Next, while connecting the speed sensor side connector 106 to the internal connector 74 for the speed sensor, it is fixed to the cover portion 43 by screw fastening or the like. In the mounting state of the terminal block module 70 and the speed sensor side connector 106 with respect to the cover portion 43, the speed sensor side connector 106 and the internal connector 74 for the speed sensor are opposed along the rotation axis X. Therefore, if the speed sensor 100 is moved along the rotation axis X toward the cover portion 43, the connection of the two connectors 74 and 106 is facilitated.

[0154] It is also possible to connect the speed sensor side connector 106 and the internal connector 74 for the speed sensor, and mount the combination of the terminal block module 70 and the speed sensor 100 to the cover portion 43 by screw fastening or the like.

[0155] Regarding the mounting of the coil end module 50 to the armature 46 and the mounting of the terminal block module 70 or the speed sensor 100 to the cover portion 43, either can be performed first.

[0156] As described above, in the state where the speed sensor side connector 106 and the internal connector 74 for the speed sensor are connected, the terminal block module integrating the terminal block module 70 and the speed sensor 100 is used as the speed sensor integrated terminal block module 44 (refer to Figure 13 ).

[0157] And, as Figure 14 shown, the cover portion 43 is fixed to the housing main body 42 by screw fastening or the like so as to close the front side opening of the housing main body 42. At this time, the tip portion of the coil end lead-out terminal 58 is disposed on the connecting member 80 along the rotation axis X through the inner opening 73h1. The tip portion of the coil end lead-out terminal 58 is disposed above the pressing piece 88.

[0158] In addition, the temperature sensor side connector 112 is also connected to the internal connector 76 for the temperature sensor along the rotation axis X. At this time, the temperature sensor side connector 112 can move within the inner connector receiving portion 55. Therefore, even if a positional deviation occurs between the connectors 76 and 112, the temperature sensor side connector 112 can be displaced in accordance with the position of the internal connector 76 for the temperature sensor. Therefore, the connectors 76 and 112 are more reliably connected.

[0159] After that, the control device 30 is installed on the rotating electric machine 40 by means of screw fastening or the like. At this time, the terminal 32 is inserted into the rotating electric machine 40 through the opening 43h. The outer bus bar terminal 38 is pressed onto the upper surface of the coil end lead-out terminal 58 located on the connecting member 80 through the outer opening 73h2. The outer bus bar terminal 38 presses the biasing member 86 into the coil end lead-out terminal 58 by means of the top end portion of the coil end lead-out terminal 58. As a result, the coil end lead-out terminal 58 is tilted with the base end as a fulcrum, and the top end portion is displaced downward. Since the biasing member 86 is compressed, the top end portion of the coil end lead-out terminal 58 is pressed against the top end portion of the outer bus bar terminal 38 by the acting force of the biasing member 86 and maintained in this state.

[0160] In addition, the outer connector 39 moves toward the external connector 78 through the opening 43h and is connected to the external connector 78. As described above, the outer connector 39 is supported by the connector receiving portion 35R so as to be movable in a direction orthogonal to the connection direction. Therefore, even if a position shift occurs between the connectors 39 and 78, the outer connector 39 can be displaced in accordance with the position of the external connector 78. Therefore, the connectors 39 and 78 are more reliably connected.

[0161] <Effects, etc.> According to the terminal block module 70 configured as described above, if the terminal block main body 72 holding the connecting member 80 is installed and fixed to the equipment housing 41, the internal connector 76 for the temperature sensor is disposed within the equipment housing 41. And if the temperature sensor side connector 112 is connected to the internal connector 76 for the temperature sensor, the temperature sensor 110 is connected to the wiring outside the rotating electric machine 40 via the temperature sensor wiring 62. Therefore, it is possible to easily connect the temperature sensor 110 installed in the rotating electric machine 40 to the wiring outside the rotating electric machine 40.

[0162] In addition, if the terminal block main body 72 is a resin member formed by die molding with at least a part of the temperature sensor wiring 62 as an insert part, the passage of liquid along the temperature sensor wiring 62 can be suppressed.

[0163] In addition, the terminal block main body 72 supports the internal connector 76 for the temperature sensor at a position facing the temperature sensor side connector 112. Therefore, when the temperature sensor or the terminal block module 70 is installed in the equipment housing 41, the internal connector 76 for the temperature sensor can be easily connected to the temperature sensor side connector 112.

[0164] Most of the various components of the rotating electric machine 40 are assembled in the direction of the rotation axis X. If the connection direction of the temperature sensor side connector 112 with respect to the internal connector 76 for the temperature sensor is set along the rotation axis X, the assembly and connection operations of the terminal block module 70 and the like can be easily performed.

[0165] In addition, if the external connector 78 has an outer terminal 79t2 for a temperature sensor connected to the wiring 62 for the temperature sensor and is supported by the terminal block body so as to be connectable to the outer connector 39 outside the device housing 41, by connecting the outer connector 39 outside the device housing 41 to the external connector 78, it is possible to easily connect the control device 30 outside the rotary electric machine 40 to the wiring 62 for the temperature sensor.

[0166] In addition, in this case, if the inner terminal 77 for the temperature sensor, the outer terminal 79t2 for the temperature sensor, and the wiring 62 for the temperature sensor are integrally formed as a metal wiring member and the wiring 62 for the temperature sensor is disposed as an insert part in the terminal block body 72, it is possible to easily manufacture the terminal block module 70 having the connectors 39 and 76. In addition, since the middle part of the wiring 62 for the temperature sensor is disposed in the terminal block body 72, the water resistance is also excellent.

[0167] In addition, since the connection direction of the outer connector 39 with respect to the external connector 78 is set to be along the direction from the outer peripheral side to the inner peripheral side of the device housing 41, it is easy to make the connection direction of the outer bus bar terminal 38 with respect to the connection member 80 coincide with the connection direction of the outer connector 39, and their connection operation can be easily performed.

[0168] In addition, the terminal block body 72 has an inner opening 73h1 and an outer opening 73h2, and the connection member 80 presses the coil end lead-out terminal 58, which is an inner bus bar terminal received through the inner opening 73h1, against the outer bus bar terminal 38 received through the outer opening 73h2. Therefore, even without performing a screwing operation for connecting the terminals 58 and 38, the terminals 58 and 38 can be easily connected.

[0169] In addition, the terminal block module 70 further includes an internal connector 74 for a speed sensor and a wiring 60 for the speed sensor. Therefore, if the speed sensor 100 is connected to the internal connector 74 for the speed sensor, the speed sensor 100 is connected to the wiring outside the rotary electric machine 40 via the wiring 60 for the speed sensor. Therefore, it is possible to easily connect the wiring 60 connected to the speed sensor 100 installed in the rotary electric machine 40 to the wiring outside the rotary electric machine 40, and the processing operation of the wiring becomes easy.

[0170] In addition, the terminal block body 72 supports the internal connector 76 for the temperature sensor and the internal connector 74 for the speed sensor in such a manner that they face the same side in the rotational axis X direction, and in this case, they face the rear side. Therefore, when the temperature sensor 110 and the speed sensor 100 are located on the same side with respect to the terminal block module 70, it is easy to connect the temperature sensor 110 to the internal connector 76 for the temperature sensor, and it is easy to connect the speed sensor 100 to the internal connector 74 for the speed sensor.

[0171] In addition, the external connector 78 has an outer terminal 79t2 for the temperature sensor connected to the wiring 62 for the temperature sensor and an outer terminal 79t1 for the speed sensor connected to the wiring 60 for the speed sensor. Therefore, by connecting the outer connector 39 outside the equipment housing 41 to the external connector 78, it is possible to easily connect the control device 30 outside the rotary electric machine 40 to the temperature sensor 110 and the speed sensor 100.

[0172] In addition, the coil end holding portion 52 of the coil end module 50 holds the temperature sensor side connector 112. Therefore, it is easy to connect the temperature sensor 110 to other wirings using the temperature sensor side connector 112.

[0173] In particular, the coil end holding portion 52 holds the temperature sensor side connector 112 at a position where it can be connected to the internal connector 76 for the temperature sensor. Therefore, it is possible to easily connect the coil end lead-out terminal 58 of the coil end module 50 and the temperature sensor 110 to the external wiring via the terminal block module 70.

[0174] [Modification Example] The connecting member does not necessarily have to be the above structure. For example, the connecting member may also have a bus bar that relays and connects the coil end lead-out terminal 58 and the outer bus bar terminal 38. In this case, for example, one end portion of the bus bar may be fixed to the coil end lead-out terminal 58 by screw fastening, and the other end portion may be connected to the outer bus bar terminal 38 by screw fastening.

[0175] In addition, the respective structures described in the above-described embodiments and each modification example can be appropriately combined as long as they do not contradict each other. Description of Reference Numerals
