Prior patent literature

Patent document 1: japanese patent laid-open publication No. 2015-133873

In the wiring member for the rotating electric machine described in patent document 1, since the holding portion is not fixed to the surrounding member, when vibration is applied, the holding portion may swing to damage the connection portion between the lead and the coil end, or the holding portion may repeatedly collide against the stator core or the like to damage the holding portion. In particular, in a wiring member for a rotating electrical machine used for a rotating electrical machine mounted on a vehicle, vibration measures are required to be implemented that can suppress damage due to vibration, because the wiring member is affected by both vibration of a cable connected to an electrode of a terminal block and vibration of the rotating electrical machine.

Detailed Description

[ embodiment ]

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1(a) is a perspective view of a stator core to which a wiring member for a rotating electric machine according to an embodiment of the present invention is attached, and fig. 1(b) is an enlarged view of a main portion of fig. 1 (a). Fig. 2 is a plan view of the stator core and the wiring member for the rotating electric machine. The rotating electrical machine 10 using the wiring member 1 for a rotating electrical machine according to the present embodiment is mounted on a vehicle driven by electric power, such as an electric vehicle or a so-called hybrid vehicle. In the following description, the rotating electrical machine 10 is described as being used as a motor, but the rotating electrical machine 10 may also be used as a generator.

The rotating electric machine 10 includes a rotor (rotating element), not shown, and a stator (stator) 11 disposed so as to surround the rotor. The rotor is configured by embedding a plurality of magnets in a rotor core made of soft magnetic metal, and rotates together with a shaft inserted through a center portion. The stator 11 includes a stator core 111 formed of a soft magnetic metal and a plurality of coil pieces 112.

In the following description, a direction parallel to the rotation axis of the shaft is referred to as an axial direction, a direction passing through the rotation axis and perpendicular to the rotation axis is referred to as a radial direction, and a direction perpendicular to the axial direction and the radial direction is referred to as a circumferential direction. In the following description, for convenience of description, one of both axial sides of the stator core 111 on which the wiring member 1 for the rotating electric machine is disposed is referred to as an upper side, and the opposite side is referred to as a lower side. However, the upper side and the lower side are not particularly limited to the upper and lower sides in the vertical direction in the state of being mounted on the vehicle.

The stator core 111 integrally includes a cylindrical back yoke 111a and a plurality of teeth 111b (see fig. 2) protruding radially inward from the back yoke 111 a. Slots 111c are formed between the teeth 111b adjacent in the circumferential direction.

Each coil piece 112 is housed and held in a slot 111c of the stator core 111. The coil piece 112 is made of a conductive metal 112M having good conductivity such as copper or aluminum, and an electrically insulating coating layer 112I covering the surface of the conductive metal 112M. In the present embodiment, the conductive metal 112M is a rectangular single line having a rectangular cross section, and the coating layer 112I is formed of a paint coat. In the coil end 113 which is an end portion of the coil piece 112, the covering layer 112I is removed to expose the conductive metal 112M. The coil pieces 112 weld the coil ends 113 to each other, and constitute two sets of three-phase (U-phase, V-phase, and W-phase) stator coils whose power angle phases are deviated from a predetermined angle.

Each coil piece 112 is fixed to the stator core 111 by an adhesive (varnish) that flows into the slot 111c and is cured. As the adhesive used for fixing the coil pieces 112, a heat-resistant material that does not lose its adhesive force by heat of the rotating electric machine 10 is preferable, and a thermosetting resin can be used. Examples of the thermosetting resin used as the adhesive include epoxy resin, phenol resin, melamine resin, urea resin, unsaturated polyester resin, alkyd resin, and the like. By bonding and fixing the coil pieces 112 to the stator core 111, sliding friction of the coil pieces 112 due to vibration can be suppressed.

The rotating electric machine 10 includes a housing (not shown) that houses the stator 11, and a terminal block (not shown) that is fixed to the housing. The terminal block has three electrodes to which three-phase alternating current is supplied from a controller. The terminal block is fixed to the housing, for example.

The rotating electrical machine 10 includes the wiring member 1 for a rotating electrical machine according to the present embodiment. The wiring member 1 for the rotating electric machine is a member for connecting the coil ends 113 of the stator 11 and the electrodes of the terminal block. In the present embodiment, the wiring member 1 for the rotating electric machine is adhesively fixed to the upper surface of the stator core 111 as the fixed member. The wiring member 1 for a rotating electric machine will be described in detail below.

(Wiring member for rotating electric machine 1)

Fig. 3 to 5 are perspective views of the wiring member 1 for the rotating electric machine. The wiring member 1 for the rotating electric machine includes a plurality of lead wires 2 and a holding portion 3 for holding the plurality of lead wires 2.

In the present embodiment, the wiring member 1 for a rotating electrical machine includes 6 leads 2 and 3 terminals 4, and 3 electrodes of the terminal block and coil ends 113 of the coil pieces 112 of each phase are connected to each other. A so-called bus ring in which a lead wire is formed annularly is known as a wiring member for a rotating electrical machine, and unlike the bus ring, the wiring member 1 for a rotating electrical machine according to the present embodiment is an acyclic wiring member in which the lead wire 2 is not formed annularly. In addition, the 6 wires 2 have high rigidity to the extent that they can maintain their own shape.

The 6 wires 2 are composed of first and second U-phase leads 21 and 22, first and second V-phase leads 23 and 24, and first and second W-phase leads 25 and 26. Each lead 2 includes a conductor 2M made of a conductive metal and an electrically insulating coating layer 2I coating the surface of the conductor 2M. As the conductive metal, copper or a copper alloy, for example, can be suitably used. The conductor 2M is a single wire (a single metal conductor that is not a twisted wire), and in the present embodiment, a round wire having a circular cross section is formed into a predetermined shape by press working. However, the conductor 2M may be formed by a straight-angled single wire having a rectangular shape in cross section.

The 3 terminals 4 include a U-phase terminal 41, a V-phase terminal 42, and a W-phase terminal 43. U-phase terminal 41 includes a plate portion 411 connected to the U-phase electrode in the terminal block, and a pressure-bonding portion 412 for pressure-bonding one end portions of first and second U-phase leads 21 and 22 together. Bolt insertion holes 410 are formed in the plate portion 411, and the plate portion 411 is connected to the U-phase electrode in the terminal block by bolts (not shown) inserted through the bolt insertion holes 410. Similarly, the V-phase terminal 42 includes a plate portion 421 connected to the V-phase electrode in the terminal block, and a pressure-bonding portion 422 for pressure-bonding one end portions of the first and second V guide wires 23 and 24 together. Bolt insertion holes 420 are formed in the plate portion 421, and the plate portion 421 is connected to the V-phase electrode in the terminal block by bolts (not shown) inserted through the bolt insertion holes 420. Similarly, the W-phase terminal 43 includes a plate portion 431 connected to the W-phase electrode in the terminal block, and a pressure-bonding portion 432 that pressure-bonds together one end portions of the first and second W-phase leads 25 and 26. Bolt insertion holes 430 are formed in the plate portion 431, and the plate portion 431 is connected to the W-phase electrode in the terminal block by bolts (not shown) inserted through the bolt insertion holes 430.

At the other end portion (end portion on the opposite side of the terminal 4) of each lead 2, the covering layer 2I is removed within a predetermined length range, and a connection portion 5 where the conductor 2M is exposed is provided. The connection portion 5 is welded to the coil ends 113 of the corresponding coil pieces 112 by tig (tungsteninert gas) welding, which is one of welding methods by arc discharge using an Inert gas. The surface of the connection portion 5 facing the coil end 113 is formed into a flat surface by press working.

The holding portion 3 includes a plurality of holders 31 for holding the respective leads 2 in a predetermined wiring shape, and a resin molding portion 32 for molding a resin so as to cover a part of the plurality of holders 31. The plurality of brackets 31 are provided so as to sandwich the lead wires 2 from above and below. The plurality of holders 31 suppress positional displacement of the lead wires 2 due to resin pressure at the time of molding of the resin mold section 32, and serve to hold the lead wires 2 in a predetermined wiring shape. The resin mold 32 is provided at a plurality of positions (here, at 7 positions) so as to collectively cover a part of the plurality of holders 31 and a part of the lead wire 2 sandwiched by the holders 31, and has an effect of integrating the plurality of holders 31.

Further, the resin mold 32 may be provided so as to cover the entirety of the plurality of holders 31, and in this case, the lead 2 is covered with resin over a wide range, and there is a possibility that heat dissipation of heat generated in the lead 2 is reduced. As in the present embodiment, since resin mold 32 is provided so as to cover only a part of holders 31 and resin mold 32 is formed so as to be spaced apart from each other, holder 31 can be integrated with sufficient strength, and exposed portions of lead 2 can be increased, thereby improving heat dissipation from lead 2.

In order that the holder 31 is melt-integrated with the resin mold 32 at the time of molding of the resin mold 32, the holder 31 and the resin mold 32 are preferably formed of the same material. The holder 31 and the resin mold 32 are preferably formed of a rigid material for holding the lead 2. Specifically, a material formed of PPS (polyphenylene sulfide), for example, can be used for the holder 31 and the resin mold 32.

At least a part (1 in the example of the drawing) of the resin mold 32 provided at a plurality of positions is provided so as to collectively cover all of the 6 wires 2. Hereinafter, the resin mold part 32 collectively covering the plurality of leads 2 is collectively referred to as a batch mold part 321. The bulk mold portion 321 is a resin mold portion 32 formed at a position closest to the terminal 4 in the longer direction of each of the wires 2 among the plurality of resin mold portions 32.

(adhesive part)

As shown in fig. 4 to 6, in the wiring member 1 for a rotating electric machine according to the present embodiment, the holding portion 3 includes an adhesive portion 33 that is adhesively fixed to the stator core 111 as a fixed member. That is, the wiring member fixing structure for the rotating electric machine according to the present embodiment is a structure in which the holding portion 3 is adhesively fixed to a fixed member. Here, the case where the fixed member is the stator core 111 is described, but the fixed member is not limited to this, and may be a housing that houses the stator 11, for example. The fixed member may be an insulating plate or a metal plate disposed on the stator core 111.

By fixing the holding portion 3 to the stator core 111 as a fixed member by bonding, it is possible to suppress the wiring member 1 for the rotating electrical machine from being swung by vibration, and it is possible to suppress the holding portion 3 from being swung to damage the connection portion between the lead wire 2 and the coil end 113, and the holding portion 3 from being repeatedly collided with the stator core 111 to damage the holding portion 3.

In the present embodiment, the adhesive portion 33 is fixed to the stator core 111 by the adhesive 330. The adhesive portion 33 has an introduction hole 331 for introducing the adhesive 330 to the interface between the adhesive portion 33 and the stator core 111. The adhesive 330 is preferably a heat-resistant adhesive that does not lose its adhesive strength by heat of the rotating electric machine 10, and a thermosetting resin can be used. Further, as the adhesive 330, an adhesive of the same material as that used for fixing the coil pieces 112 to the stator core 111 is more preferably used. Accordingly, even when the adhesive 330 flows into the introduction hole 331 during the operation of flowing the adhesive into the slot 111c of the stator core 111, the two operations of bonding and fixing the coil pieces 112 of the stator core 111 and the wiring member 1 for the rotating electric machine are performed substantially simultaneously, and the operation can be simplified. In addition, it is also conceivable that the adhesive 330 is applied to the bottom surface of the adhesive portion 33 in advance, and in this case, the position of the wiring member 1 for the rotating electrical machine is fixed before the connection portion 5 of the lead 2 is welded, and thus adjustment of the welding position may be difficult. Further, as described above, since the adhesive 330 of the adhesive portion 33 needs to be applied by another operation different from the operation of adhering the coil piece 112, it takes a lot of time in the operation. As in the present embodiment, the structure in which the adhesive 330 is introduced through the introduction hole 331 makes it easy to weld the coil ends 113 to the connection portions 5 of the leads 2 and to bond and fix the wiring member 1 for a rotating electric machine to the stator core 111.

In the present embodiment, the adhesive portion 33 has an adhesive filling portion 332 formed in a concave shape on the bottom surface of the adhesive portion 33, and the introduction hole 331 is configured to introduce the adhesive 330 into the adhesive filling portion 332. This ensures the amount of the adhesive 330 that fills the space between the adhesive portion 33 and the stator core 111, thereby more firmly bonding and fixing the adhesive portion 33 to the stator core 111. The depth of the adhesive filling portion 332 may be sufficient to fill a sufficient amount of the adhesive 330 during fixing of the adhesive portion 33, and is preferably 1mm or more.

In the illustrated example, the case where the bonding portion 33 is provided at 4 is shown. Specifically, in the present embodiment, 4 adhesive filling portions 332 are formed on the bottom surface of the bracket 31 disposed on the lowermost side (the stator core 111 side), and 4 introduction holes 331 are formed so as to be opened upward (on the opposite side to the bottom surface) and allow the adhesive 330 to be introduced into each adhesive filling portion 332. By forming the plurality of adhesive portions 33, the wiring member 1 for the rotating electric machine can be more firmly fixed to the stator core 111. Further, by forming the introduction hole 331 so as to open upward, the adhesive 330 can be easily introduced into the introduction hole 331. Further, the adhesive portion 33 (the introduction hole 331 and the adhesive filling portion 332) may be formed in the resin mold portion 32, but it is more preferable to form the introduction hole 331 and the adhesive filling portion 332 in advance in the holder 31 which can be easily molded into a complicated shape because a metal mold used for molding is complicated.

The adhesive portion 33 is preferably provided on the extending side of the plurality of wires 2 connected to the coil end 113 side (the central axis side of the stator core 111) than the bulk mold portion 321. This can suppress an increase in size of the wiring member 1 for the rotating electric machine due to the provision of the adhesive portion 33. Further, since the adhesive 330 may be difficult to be accommodated in the housing of the stator core 111 if the adhesive 330 adheres to the outer peripheral surface of the stator core 111, it is necessary to suppress leakage of the adhesive 330 to the outer peripheral side of the stator core 111, but by providing the adhesive portion 33 on the central axis side of the stator core 111 compared to the bulk molding portion 321, leakage of the adhesive 330 to the outer peripheral side of the stator core 111 is difficult.

Further, in the holding portion 3, since the vicinity of the batch mold portion 321 is the heaviest, it is desirable to provide the adhesive portion 33 at least in the vicinity of the batch mold portion 321. In the adhesive portion 33 provided closest to the batch mold portion 32, it is desirable to increase the adhesive force as much as possible in order to suppress the peeling of the batch mold portion 321 against the vibration. Therefore, in the present embodiment, the adhesive filling portion 332 of the adhesive portion 33 provided closest to the batch molding portion 321 is maximized (the opening area and the volume of the adhesive filling portion 332 are maximized).

(method of manufacturing rotating electric machine 10)

In manufacturing the rotating electric machine 10, first, the coil pieces 112 are inserted into the slots 111c of the stator core 111, and the coil pieces 112 on the coil end 113 side are subjected to twisting processing to finish the shapes of the coil pieces 112. Then, the connection portion 5 of each lead wire 2 in the wiring member 1 for the rotating electric machine is welded to the corresponding coil end 113 by TIG welding.

Then, the adhesive is flowed into the slot 111c of the stator core 111, and the adhesive 330 is flowed into the adhesive filling portion 332 through the introduction hole 331, so that the stator 11 and the wiring member 1 for the rotating electric machine enter the thermostatic bath and are heated, thereby thermally curing the adhesive 330. Thereby, the coil pieces 112 are adhesively fixed to the stator core 111, and the wiring member 1 for the rotating electric machine is adhesively fixed to the stator core 111. The rotary electric machine 10 can be obtained by housing a stator 11 to which the wiring member 1 for a rotary electric machine is bonded and fixed in a housing, connecting the terminals 4 of the respective leads 2 to the corresponding electrodes of the terminal block, and housing a rotor manufactured by another method in the stator 11.

(modification example)

In the above-described embodiment, the adhesive filling portion 332 is formed in the holding portion 3, and as shown in fig. 7(a), a concave adhesive filling portion 332 may be formed in the upper surface of the stator core 111 as the member to be fixed. As shown in fig. 7(b), an adhesive filling portion 332 may be formed in both the holding portion 3 and the stator core 111.

Although not mentioned in the above embodiment, as shown in fig. 8(a), when the adhesive 330 is filled into the adhesive filling portion 332, an air hole 333 for releasing air in the adhesive filling portion 332 may be provided. This can suppress a filling failure of the adhesive 330 due to the failure to discharge air in the adhesive filling portion 332. Further, although the air hole 333 is provided so as to open upward in fig. 8(a), the air hole 333 may be provided so as to open laterally (in a direction perpendicular to the axial direction). In this case, however, in order to prevent the adhesive 330 from leaking from the air holes 333 to the outer peripheral side of the stator core 111, the air holes 333 are preferably formed so as to open radially inward. Air holes 333 can also be provided in the stator core 111.

Further, although the introduction hole 331 is formed so as to open upward in the above-described embodiment, the introduction hole 331 may be formed so as to open laterally (in a direction perpendicular to the axial direction), for example, as shown in fig. 8 (b). In this case, in order to suppress leakage of the adhesive 330 to the outer peripheral side of the stator core 111 when the adhesive is introduced into the introduction hole 331, the introduction hole 331 is preferably formed so as to open to the radially inner side. In addition, from the viewpoint of easy introduction of the adhesive 330, the introduction hole 331 is more preferably formed so as to open upward.

Although not mentioned in the above embodiment, a resin mold may be further provided so as to cover the stator core 111, the coil pieces 112, and a part of the wiring member 1 for the rotating electric machine, which are fixed members. In the present embodiment, since the holding portion 3 is adhesively fixed to the stator core 111 as the fixed member, it is possible to suppress the occurrence of positional deviation of the wiring member 1 for the rotating electrical machine due to resin pressure at the time of resin molding.

(operation and Effect of the embodiment)

As described above, the wiring member 1 for the rotating electric machine according to the present embodiment includes the holding portion 3 that holds the plurality of leads 2, and the holding portion 3 includes the adhesive portion 33 that is adhesively fixed to the fixed member (here, the stator core 111).

Thus, since the wiring member 1 for the rotating electrical machine is adhesively fixed to the fixed member (here, the stator core 111), it is possible to suppress damage to the connection portion between the lead wire 2 and the coil end 113 due to the vibration caused by the swinging of the holding portion 3, and damage to the holding portion 3 due to the repeated collision of the holding portion 3 against the stator core 111.
