Description

[Technical Field]

[0001] The disclosure herein relates to a power supply. [Background technology]

[0002] Patent Document 1 describes an inverter that includes a circuit board, a terminal block, and a case that houses them. The terminal block is fixedly installed near the top of the case, and the circuit board is located behind the terminal block. A fall prevention wall is provided on the top surface of the terminal block to prevent foreign objects from slipping off the terminal block. The case also has multiple service holes, which are openings that allow access to the terminal block, at positions facing the terminal block. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5287829 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, an opening is provided between a fall prevention wall and a wall opposite the fall prevention wall, connecting the upper side and the back side of the case. The length of the opening in the direction in which the fall prevention wall and the wall opposite the fall prevention wall are aligned is longer than the length between adjacent service holes. There is a risk that foreign matter that is not completely prevented by the fall prevention wall will come into contact with a circuit board placed at the back side of the case through the opening.

[0005] Therefore, an object of the present disclosure is to provide a power supply device that prevents foreign matter from coming into contact with a substrate. [Means for solving the problem]

[0006] A power supply device according to one aspect of the present disclosure includes: A first terminal block (91) and a second terminal block (92), a substrate (24A) provided at a position away from the first terminal block and the second terminal block in a direction perpendicular to the direction perpendicular to the direction in which the first terminal block and the second terminal block are arranged; a housing (60) having a bottom wall (61) on which a substrate is provided, a partition wall (63) on which a first terminal block and a second terminal block are provided at a position farther from the bottom wall in the perpendicular direction than the substrate, and a top wall (64) provided at a position farther from the partition wall in the perpendicular direction than the first terminal block and the second terminal block; a first service hole (64A) penetrating in the orthogonal direction is provided in a portion of the top wall that overlaps with the first terminal block in the orthogonal direction; a second service hole (64B) penetrating in the orthogonal direction is provided in a portion of the top wall that overlaps with the second terminal block in the orthogonal direction; a through-hole (63A) is provided in a portion of the partition wall between the first service hole and the second service hole, the through-hole penetrating in the perpendicular direction and not overlapping with the first service hole and the second service hole in the perpendicular direction; A part of the first terminal block is provided between the first service hole and the through hole, and a part of the second terminal block is provided between the second service hole and the through hole. 、 Further provided is a first conductive member (21B) and a second conductive member (22B) connected to the substrate, The first and second conductive members extend through the through holes from the second space (60B) between the bottom wall and the partition wall toward the first space (60A) between the partition wall and the top wall.

[0007] This makes it difficult for foreign matter to pass through the through-holes (63A), thereby preventing foreign matter from coming into contact with the substrate (24A).

[0010] Hereinafter, several embodiments for carrying out the present disclosure will be described with reference to the drawings. In each embodiment, parts corresponding to matters described in the preceding embodiment will be assigned the same reference numerals, and duplicated explanations may be omitted. In each embodiment, when only a part of the configuration is described, the other previously described embodiments may be applied to the other parts of the configuration.

[0011] In addition, it is not only possible to combine parts that are explicitly stated as being possible in each embodiment, but it is also possible to partially combine embodiments, embodiments and variants, and variants even if not explicitly stated, as long as there are no particular problems with the combination.

[0012] (First embodiment) A power supply system 1 and a power supply device 30 according to this embodiment will be described with reference to Figures 1 to 5. The power supply system 1 and the power supply device 30 are applied to electrically powered vehicles such as electric vehicles and plug-in hybrid vehicles.

[0013] <Power supply system and power supply equipment> As shown in FIG. 1, a power supply device 30 is included in a power supply system 1 of a vehicle. The power supply device 30 includes a battery pack 10 and a distribution module 20. The power supply system 1 includes the battery pack 10, the distribution module 20, a first vehicle load 41, a second vehicle load 42, an FrPCU 51, an FrMG 52, an RrPCU 53, and an RrMG 54. A DC power supply 70 and an AC power supply 80 are connected to the power supply system 1 from the outside. PCU stands for Power Control Unit. MG stands for Motor Generator. ECU stands for electronic control unit. Note that the FrMG 52 corresponds to the first motor, and the RrMG 54 corresponds to the second motor.

[0014] As a power supply path, the battery pack 10 and the distribution module 20 are electrically connected via conductive members such as a wire harness or a bus bar. The first vehicle load 41, the second vehicle load 42, the FrPCU 51, and the RrPCU 53 are electrically connected to the distribution module 20 via conductive members. The FrMG 52 is electrically connected to the FrPCU 51 via a conductive member. The RrMG 54 is electrically connected to the RrPCU 53 via a conductive member.

[0015] In the following description, the terms "lines" refer to conductive members such as wire harnesses and bus bars. The FrPCU 51 and RrPCU 53 are equipped with inverters and converters for power conversion. The on-off control of the switches included in these inverters and converters is controlled by the vehicle ECU. The FrPCU 51 and RrPCU 53 are controlled by the vehicle ECU.

[0016] The DC power output from the battery pack 10 is supplied to the first vehicle load 41, the second vehicle load 42, the FrPCU 51, and the RrPCU 53 via the distribution module 20. The FrPCU 51 and the RrPCU 53 convert the supplied DC power into AC power. Conversely, the FrPCU 51 and the RrPCU 53 convert the supplied AC power into DC power. The FrMG 52 and the RrMG 54 are motor generators for vehicle travel that provide propulsion force to the vehicle. The FrMG 52 is powered by the AC power supplied from the FrPCU 51. The RrMG 54 is powered by the AC power supplied from the RrPCU 53.

[0017] The front wheels rotate when the FrMG52 is powered. The rear wheels rotate when the RrMG54 is powered. The FrMG52 also generates regenerative power using the vehicle's propulsion force. The AC power generated by this regenerative power generation is converted into DC power by the FrPCU51. The RrMG54 also generates regenerative power using the vehicle's propulsion force. The AC power generated by this regenerative power generation is converted into DC power by the RrPCU53. This DC power is supplied to the first vehicle load 41 and the second vehicle load 42 via the distribution module 20. This DC power is supplied to the battery pack 10 via the distribution module 20.

[0018] For ease of notation, the DC power supplied from the battery pack 10 will be referred to as source power. Power generated by regenerative power generation and converted to DC power by the FrPCU 51 and RrPCU 53 will be referred to as regenerated power. The distribution module 20 serves to supply source power and regenerated power output within the vehicle to various electrical devices mounted on the vehicle. Furthermore, the distribution module 20 serves to supply charging power supplied from an external power source to various electrical devices mounted on the vehicle. Below, the components of the battery pack 10 and the distribution module 20 will be described individually.

[0019] <Battery pack> The battery pack 10 has an assembled battery 11, an SMR 12, a power relay 13, a battery ECU 14, and battery connectors 15A and 15B. The operation of the SMR 12 and the power relay 13 is controlled by the battery ECU 14. The output to the battery connectors 15A and 15B is controlled to be energized or cut off by the operation of the SMR 12 and the power relay 13. The output to the distribution module 20 is controlled to be energized or cut off by the operation of the SMR 12 and the power relay 13. In the drawings, the battery ECU 14 is abbreviated as "BAECU."

[0020] The battery pack 11 has a plurality of battery cells connected in series. A voltage corresponding to the potential difference between the positive terminal of the battery cell with the highest potential and the negative terminal of the battery cell with the lowest potential among the plurality of battery cells connected in series corresponds to the power supply voltage of the battery pack 11. The battery cells included in this battery pack 11 can be, for example, secondary batteries such as lithium-ion batteries.

[0021] One end of a first power supply line 10A is connected to the positive terminal of the battery cell with the highest potential among the multiple battery cells connected in series.

The battery ECU 14 communicates with an on-board ECU and a power supply ECU 26 (described later) via wiring (not shown). The battery ECU 14 controls the operation of the SMR 12 and the power supply relay 13 based on communication with these ECUs.

The other ends of the third power supply line 10C and the fourth power supply line 10D are connected to the second battery connector 15B. The connection and disconnection of each of these four power supply lines is controlled by outputting or not outputting a drive signal from the battery ECU 14 to the SMR 12 and the power supply relay 13.

The DC relays 23A and 23B are mechanical switches. The DC relays 23A and 23B are switches that switch between an ON state and an OFF state in response to a drive signal input from the power supply ECU 26. The DC-DC converter 24 reduces the supplied power to 12 V and supplies it to the second vehicle load 42. The AC-DC converter 25 converts AC power supplied from the AC power source 80 into DC power. In the drawings, the power supply ECU 26 is abbreviated as "PDECU." The power supply ECU 26 corresponds to an electrical component. The power supply ECU 26 may also be referred to as a control device.

[0052] As shown in FIGS. 4 and 5 , the terminal block unit 90 includes a first terminal block 91, a second terminal block 92, and a connecting wall 93.

[0053] The length of the first connecting wall 93A in the TD direction and the length of the second connecting wall 93B in the TD direction are set to a length that prevents foreign matter such as dust or dirt from moving toward the through-hole 63A due to vibrations or the like even if the foreign matter enters the inside of the housing 60.

[0054] The first terminal block 91 and the second terminal block 92 are integrally connected via a first connecting wall 93A and a second connecting wall 93B. An opening 94 opening in the TD direction is defined by the first terminal block 91, the second terminal block 92, the first connecting wall 93A, and the second connecting wall 93B. The through hole 63A is surrounded on all four sides by the first terminal block 91, the second terminal block 92, the first connecting wall 93A, and the second connecting wall 93B. As shown in FIG. 4 , the opening 94 and the through hole 63A overlap in the TD direction. The opening 94 and the through hole 63A communicate with each other in the TD direction. For example, the width of the opening 94 in the DP direction is equal to the width of the through hole 63A in the DP direction. Note that the width of the opening 94 and the width of the through hole 63A do not have to be equal. The width of the through hole 63A may be narrower than the width of the opening 94.

[0055] The first terminal block 91 includes a first support portion 91A, a first inner wall 91B, and a first outer wall 91C.

The first inner wall 91B corresponds to the first support wall.

[0056] A first inner wall 91B is provided at the end of the first support portion 91A on the second wall portion 62B side. A first outer wall 91C is provided at the end of the first support portion 91A on the fourth wall portion 62D side. The first inner wall 91B and the first outer wall 91C extend away from the first support portion 91A toward the cover 64. Between the first inner wall 91B and the first outer wall 91C, there are provided the first positive electrode branch line 21E, the first negative electrode branch line 22E, the conductive members of the FrPCU connector 28F, and a connecting member 100 that connects these together.

[0057] The second terminal block 92 includes a second support portion 92A, a second inner wall 92B, and a second outer wall 92C. The second support portion 92A is provided with a second positive branch line 21F, a second negative branch line 22F, and the conductive member of the RrPCU connector 28G. The second positive branch line 21F, the second negative branch line 22F, and the conductive member of the RrPCU connector 28G are connected and fixed to the second support portion 92A by a connecting member 100. The second inner wall 92B corresponds to the second support wall.

[0058] A second inner wall 92B is provided at the end of the second support portion 92A on the fourth wall portion 62D side. A second outer wall 92C is provided at the end of the second support portion 92A on the second wall portion 62B side. The second inner wall 92B and the second outer wall 92C extend away from the second support portion 92A toward the cover 64. Between the second inner wall 92B and the second outer wall 92C, there are provided the second positive electrode branch line 21F, the second negative electrode branch line 22F, and conductive members of the RrPCU connector 28G, as well as a connecting member 100 that connects these.

[0059] The cover 64 is also provided with a first service hole 64A that allows access to a coupling member 100 that couples the first branch lines 21E, 22E to the conductive members of the FrPCU connector 28F. The first service hole 64A is provided at a position on the cover 64 that overlaps with the first terminal block 91 in the TD direction. More specifically, the first service hole 64A is provided at a position on the cover 64 that overlaps with the coupling member 100 that couples the first branch lines 21E, 22E to the conductive members of the FrPCU connector 28F. The first service hole 64A is provided within the projection area of ​​the first terminal block 91 in the TD direction.

[0060] The cover 64 is provided with a second service hole 64B that allows access to a coupling member 100 that couples the second branch lines 21F, 22F to the conductive members of the RrPCU connector 28G. The second service hole 64B is provided at a position on the cover 64 that overlaps with the second terminal block 92 in the TD direction.

The second service hole 64B is provided within the projection area of ​​the second terminal block 92 in the TD direction.

[0061] As described above, the first service hole 64A, the second service hole 64B, and the through hole 63A are spaced apart in the DP direction. Furthermore, the first service hole 64A and the second service hole 64B do not overlap with the through hole 63A in the TD direction. The through hole 63A is located between the first service hole 64A and the second service hole 64B in the DP direction. The width of the through hole 63A in the DP direction is narrow enough to allow it to be located between the first service hole 64A and the second service hole 64B.

[0062] Service holes 64A and 64B are holes provided in cover 64 for a worker to perform wiring work. Power supply device 30 is assembled in a process separate from the vehicle assembly process, and then delivered to the vehicle assembly process, where assembly work is carried out. In the vehicle assembly process, power supply device 30 needs to be wired to external components. In order to perform this wiring work without removing the components of power supply device 30 from housing 60, first service hole 64A and second service hole 64B are provided in housing 60.

[0063] <Service holes and through holes> 4, a first terminal block 91 and a second terminal block 92 are provided on the partition wall 63. The first terminal block 91 is provided at a position on the partition wall 63 closer to the fourth wall portion 62D than the through-hole 63A. The second terminal block 92 is provided at a position on the partition wall 63 closer to the second wall portion 62B than the through-hole 63A.

[0064] A first edge 65A of the edge of first service hole 64A on the second service hole 64B side is located closer to the fourth wall 62D than a first inner surface 63B of the inner wall of through hole 63A on the fourth wall 62D side. A second edge 65B of the edge of second service hole 64B on the first service hole 64A side is located closer to the second wall 62B than a second inner surface 63C of the inner wall of through hole 63A on the second wall 62B side. The first service hole 64A is located at a position overlapping with the first terminal block 91 on the cover 64 in the TD direction. The second service hole 64B is located at a position overlapping with the second terminal block 92 on the cover 64 in the TD direction.

[0065] A first terminal block 91 is provided on the partition wall 63 so that the coupling member 100 that couples the first branch lines 21E, 22E and the FrPCU connector 28F can be accessed from the first service hole 64A. A second terminal block 92 is provided on the partition wall 63 so that the coupling member 100 that couples the second branch lines 21F, 22F and the RrPCU connector 28G can be accessed from the second service hole 64B.

[0066] Furthermore, a first inner wall 91B extends from the first support portion 91A toward the cover 64. The first inner wall 91B is provided closer to the second edge portion 65B than the first edge portion 65A. The first inner wall 91B is provided between the first service hole 64A and the through hole 63A. The height of the first inner wall 91B in the TD direction is set to a height that prevents foreign matter such as dust and dirt from moving into the interior through the first service hole 64A.

[0067] A second inner wall 92B extends from the second support portion 92A toward the cover 64. The second inner wall 92B is provided closer to the first edge portion 65A than the second edge portion 65B. The second inner wall 92B is provided between the second service hole 64B and the through hole 63A. The height of the second inner wall 92B in the TD direction is set to a height that prevents foreign matter from moving into the through hole 63A even if the foreign matter enters the interior through the second service hole 64B.

[0068] As described above, the substrate 24A is provided in the second space 60B. The substrate 24A is provided on the bottom wall 61. The second positive electrode line 21B and the second negative electrode line 22B are connected to the substrate 24A. The second positive electrode line 21B and the second negative electrode line 22B pass through the through-hole 63A and extend from the second space 60B to the first space 60A. The second positive electrode line 21B and the second negative electrode line 22B extend from the second space 60B toward the first space 60A, closer to the cover 64 than the second connecting wall 93B in the TD direction. The second positive electrode line 21B and the second negative electrode line 22B pass between the second connecting wall 93B and the cover 64 in the first space 60A and extend toward the first wall portion 62A.

[0069] The width of the opening of the through hole 63A in the DP direction is narrow enough to allow the second positive electrode line 21B and the second negative electrode line 22B to pass through. It can also be said that the length between the edges of the opening of the through hole 63A in the DP direction is short enough to allow the second positive electrode line 21B and the second negative electrode line 22B to pass through.

[0070] Furthermore, in the DP direction, the opening width of the opening 94 is narrower than the opening width of the through hole 63A. The first inner wall 91B is provided closer to the second wall portion 62B than the first inner surface 63B. The second inner wall 92B is provided closer to the fourth wall portion 62D than the second inner surface 63C. In other words, it can be said that the first inner wall 91B is provided closer to the center of the through hole 63A than the first inner surface 63B. It can also be said that the second inner wall 92B is provided closer to the center of the through hole 63A than the second inner surface 63C.

[0071] Furthermore, the first terminal block 91 and the second terminal block 92 may be provided with a lightening hole due to product design. In this case, there is a risk that foreign matter that has entered the interior through the service holes 64A, 64B may pass through the gap between the first terminal block 91 and the second terminal block 92 and the partition wall 63 and fall into the second space 60B through the through-hole 63A. To prevent such foreign matter from falling into the second space 60B, the first terminal block 91 and the second terminal block 92 are provided with a movement prevention wall 95 that contacts the partition wall 63 and can prevent the movement of foreign matter. In another embodiment, the first terminal block 91 and the second terminal block 92 may not be provided with a lightening hole. In that case, the first terminal block 91 and the second terminal block 92 may be provided so as to contact the partition wall 63.

[0072] <Action and effect> As described above, the terminal block unit 90 is provided in the first space 60A. The board 24A is provided in the second space 60B. The first terminal block 91 and the second terminal block 92 are provided on the partition wall 63, spaced apart in the DP direction. A first inner wall 91B extends from the first support portion 91A toward the cover 64. A second inner wall 92B extends from the second support portion 92A toward the cover 64.

[0073] A first service hole 64A is provided in the cover 64 at a position where the first terminal block 91 overlaps. A second service hole 64B is provided in the cover 64 at a position where the second terminal block 92 overlaps. A through hole 63A that opens in the TD direction is provided in the partition wall 63. The through hole 63A is provided between the first service hole 64A and the second service hole 64B in the DP direction. The first service hole 64A and the second service hole 64B do not overlap with the through hole 63A in the TD direction.

[0074] A first inner wall 91B, which is part of first terminal block 91, is provided between first service hole 64A and through hole 63A. A second inner wall 92B, which is part of second terminal block 92, is provided between second service hole 64B and through hole 63A. Through hole 63A is small enough to be provided between first service hole 64A and second service hole 64B.

[0075] A first inner wall 91B is provided between this through hole 63A and the first service hole 64A. A second inner wall 92B is provided between this through hole 63A and the second service hole 64B. This makes it difficult for foreign matter to pass through the through hole 63A. As a result, foreign matter is prevented from coming into contact with the board 24A housed in the second space 60B. Since foreign matter is prevented from coming into contact with the board 24A without increasing the number of parts, this also helps to prevent an increase in the physical size. This also leads to improved quality.

[0076] As described above, the first terminal block 91 and the second terminal block 92 are integrally connected via the first connecting wall 93A and the second connecting wall 93B. The through hole 63A is surrounded on all four sides by the first terminal block 91, the second terminal block 92, the first connecting wall 93A, and the second connecting wall 93B. This makes it difficult for foreign matter to pass through the through hole 63A from any direction. Accordingly, it becomes difficult for foreign matter to pass through the through hole 63A.

[0077] As explained above, first service hole 64A is provided within the projection area of ​​first terminal block 91 in the TD direction. Second service hole 64B is provided within the projection area of ​​second terminal block 92 in the TD direction. The width of the opening of first service hole 64A and the width of the opening of second service hole 64B are narrow enough for an operator to perform their work. This makes it difficult for foreign matter to enter the inside of housing 60. Foreign matter is less likely to pass through the narrow openings of first service hole 64A and second service hole 64B and into through-hole 63A.

[0078] As described above, the second positive electrode line 21B and the second negative electrode line 22B are connected to the substrate 24A. The second positive electrode line 21B and the second negative electrode line 22B extend from the second space 60B toward the first space 60A through the through hole 63A. The opening width of the through hole 63A in the DP direction is narrow enough to allow the second positive electrode line 21B and the second negative electrode line 22B to pass through. This makes it even more difficult for foreign matter to pass through the through hole 63A. This effectively prevents foreign matter from coming into contact with the substrate 24A housed in the second space 60B.

[0079] As described above, the positive electrode Fr line 29A, the negative electrode Fr line 29B, the positive electrode Rr line 29C, and the negative electrode Rr line 29D pass through the through hole 63A. The positive electrode Fr line 29A and the positive electrode Rr line 29C include the second positive electrode line 21B. The negative electrode Fr line 29B and the negative electrode Rr line 29D include the second negative electrode line 22B. The through hole 63A is provided between the FrPCU connector 28F and the RrPCU connector 28G in the DP direction.

[0080] The FrMG 52 connected to the FrPCU connector 28F and the RrMG 54 connected to the RrPCU connector 28G are provided in the same space in a vehicle, for example. Accordingly, the FrPCU connector 28F and the RrPCU connector 28G are sometimes provided adjacent to each other to ensure efficient wiring. In this case, the FrPCU connector 28F and the RrPCU connector 28G are provided adjacent to each other, separated by, for example, a tool clearance.

[0081] There may be a situation where a space sufficient to accommodate electrical components cannot be secured between the FrPCU connector 28F and the RrPCU connector 28G, resulting in a dead space. In this embodiment, a through-hole 63A is intentionally provided in this dead space. The second positive electrode line 21B and the second negative electrode line 22B pass through the through-hole 63A. In this way, this embodiment can utilize the dead space while preventing foreign matter from coming into contact with the circuit board 24A.

[0082] As described above, the first inner wall 91B is provided closer to the center of the through hole 63A than the first inner surface 63B. The second inner wall 92B is provided closer to the center of the through hole 63A than the second inner surface 63C. This makes it difficult for foreign matter to pass between the first inner wall 91B and the second inner wall 92B. Accordingly, it becomes difficult for foreign matter to pass through the through hole 63A.

[0083] (Second embodiment) 6, in the second embodiment, the terminal block unit 90 does not necessarily have to include the connecting wall 93. In the second embodiment, the first terminal block 91 and the second terminal block 92 are provided spaced apart in the DP direction. The second embodiment also provides the same effects as the first embodiment.

[0084] (Third embodiment) As shown in FIG. 7 , in the third embodiment, the power supply device 30 is provided with buffer materials 310 capable of suppressing vibrations to the terminal block unit 90. Examples of the buffer materials 310 include sponges and gel-like materials. The buffer materials 310 are provided between the partition wall 63 and the first terminal block 91 and between the partition wall 63 and the second terminal block 92. This suppresses transmission of vibrations to the terminal block unit 90. Accordingly, poor electrical connections between the first branch lines 21E and 22E and the FrPCU connector 28F are suppressed. Poor electrical connections between the second branch lines 21F and 22F and the RrPCU connector 28G are suppressed.

[0085] (Fourth embodiment) As shown in FIG. 8, in the fourth embodiment, the power supply device 30 is provided with an adhesive 410 capable of capturing foreign matter that has entered through the first service hole 64A and the second service hole 64B. Examples of the adhesive 410 include adhesive tape and a gel-like material. The adhesive 410 is provided between the partition wall 63 and the first terminal block 91, and between the partition wall 63 and the second terminal block 92. The foreign matter is likely to be captured by the adhesive 410 before passing through the through-hole 63A. This prevents the foreign matter from coming into contact with the substrate 24A. The adhesive 410 corresponds to a capturing member.

[0086] (Fifth embodiment) As shown in Fig. 9, in the fifth embodiment, the power supply device 30 is provided with a magnetic body 510 capable of capturing metallic foreign matter that has entered through the first service hole 64A and the second service hole 64B. The magnetic body 510 is provided between the partition wall 63 and the first terminal block 91, and between the partition wall 63 and the second terminal block 92. The metallic foreign matter is likely to be captured by the magnetic body 510 before passing through the through-hole 63A. This prevents the foreign matter from coming into contact with the circuit board 24A. The magnetic body 510 corresponds to a capturing member.

[0087] (Sixth embodiment) 10 , in the sixth embodiment, a first recess 611 recessed toward the bottom wall 61 is provided at a portion of the partition wall 63 facing the first terminal block 91, and a second recess 612 recessed toward the bottom wall 61 is provided at a portion of the partition wall 63 facing the second terminal block 92. Foreign matter is likely to be captured by the first recess 611 and the second recess 612 before passing through the through-hole 63A. This prevents the foreign matter from coming into contact with the substrate 24A. It can also be said that the first recess 611 and the second recess 612 form a capture structure 610 capable of capturing foreign matter.

[0088] (Seventh embodiment) As shown in FIG. 11 , in the seventh embodiment, the power supply device 30 is provided with a blocking member 710 that blocks the through-hole 63A and allows the second positive electrode line 21B and the second negative electrode line 22B to pass through. The blocking member 710 is formed, for example, primarily from a resin. For example, the second positive electrode line 21B and the second negative electrode line 22B are insert-molded into the blocking member 710. The blocking member 710 is provided to block the through-hole 63A. The blocking member 710 also serves as a wall that separates the first space 60A from the second space 60B. The blocking member 710 prevents foreign matter from passing between the first space 60A and the second space 60B. This prevents foreign matter that has entered the interior through the service holes 64A and 64B from contacting the substrate 24A provided in the second space 60B.

[0089] (Eighth embodiment) 12, in the eighth embodiment, a guide wall 810 capable of guiding foreign matter is provided on the partition wall 63. The guide wall 810 extends, for example, from the partition wall 63 toward the bottom wall 61. The substrate 24A is housed between the partition wall 63 and the guide wall 810 in the second space 60B. The guide wall 810 extends closer to the bottom wall 61 than the substrate 24A. This prevents foreign matter from coming into contact with the substrate 24A, since the foreign matter is guided along the guide wall 810 to the bottom wall 61 even if it passes through the through-hole 63A.

[0090] (Other embodiments) In the embodiments described so far, a configuration has been described in which the FrPCU connector 28F is provided on the first terminal block 91, and the RrPCU connector 28G is provided on the second terminal block 92. However, it is not necessary that the FrPCU connector 28F is provided on the first terminal block 91, and the RrPCU connector 28G is provided on the second terminal block 92. For example, the first load connector 28C may be provided on the first terminal block 91, and the second load connector 28D may be provided on the second terminal block 92. Note that the supply connectors 28 provided on the first terminal block 91 and the second terminal block 92 are not limited to this, and any combination may be used.
