[0003] [Patent Document 1] Japanese Patent Application Publication No. 2022-150994 Summary of the Invention [Problem to be solved by the invention]

[0004] In such an electric compressor, it is desirable to stably support the high-voltage harness and the low-voltage harness on the housing via brackets. [Means for solving the problem]

[0005] An electric compressor that solves the above problem comprises a compression unit that compresses a fluid, a motor that drives the compression unit, an inverter that drives the motor, a housing that accommodates the compression unit, the motor, and the inverter, a high-voltage connector that is provided in the housing and electrically connected to the inverter, a low-voltage connector that is provided in the housing and electrically connected to the inverter, and a bracket that is fixed to the housing, wherein a high-voltage harness connected to the high-voltage connector and a low-voltage harness connected to the low-voltage connector are supported on the housing via the bracket, and the bracket has a fixing plate portion fixed to the housing, a first fixing plate portion to which the high-voltage harness is attached, and a second fixing plate portion to which the low-voltage harness is attached, wherein the first fixing plate portion is bent from a first end of the fixing plate portion and extends away from the housing, and the second fixing plate portion is bent from the first fixing plate portion and extends toward the second end of the fixing plate portion.

[0006] According to this, the strength of the second mounting plate is easily ensured by the fixed plate and the first mounting plate. Therefore, the low-voltage harness can be stably supported on the housing via the bracket. Furthermore, because the fixed plate and the second mounting plate are bent from the first mounting plate, the fixed plate and the second mounting plate function as ribs for the first mounting plate. As a result, the strength of the first mounting plate is easily ensured. Therefore, the high-voltage harness, which is heavier than the low-voltage harness, can be stably supported on the housing via the bracket. As described above, the high-voltage harness and the low-voltage harness can be stably supported on the housing via the bracket.

[0007] In the above-described electric compressor, the first mounting plate portion has a first locking hole configured to be able to lock a first retaining clip that holds the high-voltage harness, and the second mounting plate portion has a second locking hole configured to be able to lock a second retaining clip that holds the low-voltage harness, and the first locking hole locks the first retaining clip so that the high-voltage harness is positioned on a surface of the first mounting plate portion that is located opposite the fixing plate portion, and the second locking hole locks the second retaining clip so that the low-voltage harness is positioned on a surface of the second mounting plate portion that is located opposite the fixing plate portion.

[0008] With this, the high-voltage harness can be attached to the first mounting plate simply by engaging the first retaining clip with the first locking hole, and the low-voltage harness can be attached to the second mounting plate simply by engaging the second retaining clip with the second locking hole. The high-voltage harness is arranged on the surface of the first mounting plate opposite the fixing plate, and the low-voltage harness is arranged on the surface of the second mounting plate opposite the fixing plate. Therefore, the high-voltage harness and the low-voltage harness can be stably supported on the housing via the bracket without interfering with each other.

[0009] In the above-described electric compressor, the first mounting plate portion has a connection portion that connects the fixed plate portion and the second mounting plate portion and is positioned opposite the high-voltage connector, and an extension portion that extends from the connection portion in a direction away from the fixed plate portion and the second mounting plate portion and in which the first locking hole is formed, and the first locking hole locks the first retaining clip so that the high-voltage harness is positioned relative to the first mounting plate portion in a bent state so that it extends from the high-voltage connector toward the connection portion and extends along the extension portion.

[0010] This allows the distance between the high-voltage connector and the first locking hole to be longer than when the first locking hole is formed in the connection portion, for example. Therefore, the high-voltage harness can be arranged on the first mounting plate in a bent state so as to extend from the high-voltage connector toward the connection portion and extend along the extension portion, making it easier to lock the first retaining clip into the first locking hole. This allows for better handling of the high-voltage harness.

[0011] In the electric compressor, the bracket may have a fixing plate rib formed by bending a side portion of the fixing plate. This allows the fixing plate rib to improve the strength of the fixing plate, which in turn makes it easier to ensure the strength of each of the first and second mounting plates, thereby enabling the high-voltage and low-voltage harnesses to be more stably supported on the housing via the bracket.

[0012] In the electric compressor, the bracket may have a first mounting plate rib formed by bending a side portion of the first mounting plate. This allows the first mounting plate rib to improve the strength of the first mounting plate, making it easier to ensure the strength of each of the first and second mounting plates, and therefore allowing the high-voltage and low-voltage harnesses to be more stably supported on the housing via the bracket.

[0013] In the electric compressor, the bracket may have a reinforcing rib formed by recessing a part of the bent portion of the first mounting plate portion relative to the fixed plate portion. This allows the reinforcing rib to improve the strength of the bent portion of the first mounting plate relative to the fixed plate, making it easier to ensure the strength of the first mounting plate.This allows the high-voltage harness and the low-voltage harness to be more stably supported on the housing via the bracket. [Effects of the Invention]

[0014] According to this invention, the high voltage harness and the low voltage harness can be stably supported on the housing via the bracket. [Brief explanation of the drawings]

[0016] An embodiment of an electric compressor will now be described with reference to Figures 1 to 6. The electric compressor of this embodiment is used in, for example, a vehicle air conditioner. <Outline of electric compressor> As shown in FIG. 1 , the electric compressor 10 includes a housing 11. The housing 11 is cylindrical. The housing 11 includes a discharge housing 12, a motor housing 13, and an inverter housing 14. The discharge housing 12, the motor housing 13, and the inverter housing 14 are connected to each other and arranged in this order in the axial direction of the housing 11. The discharge housing 12, the motor housing 13, and the inverter housing 14 are made of a metal material. The discharge housing 12, the motor housing 13, and the inverter housing 14 are made of, for example, aluminum.

[0017] The electric compressor 10 includes a compression unit 15, a motor 16, and an inverter 17. The motor 16 is housed in a motor housing 13. The compression unit 15 is housed in the housing 11 on the opposite side of the inverter housing 14 from the portion of the housing 11 in which the motor 16 is housed. The inverter 17 is housed in the inverter housing 14. Thus, the housing 11 houses the compression unit 15, the motor 16, and the inverter 17.

[0018] The compression unit 15 compresses the refrigerant as a fluid. The compression unit 15 is, for example, a scroll type having a fixed scroll (not shown) fixed to the housing 11 and an orbiting scroll (not shown) arranged opposite the fixed scroll. The motor 16 drives the compression unit 15. The inverter 17 drives the motor 16. The compression unit 15, motor 16, and inverter 17 are arranged in this order in the axial direction of the housing 11.

[0019] 1 and 2, the inverter housing 14 has a housing main body 18 and a connector connection portion 19. The housing main body 18 is cylindrical. The housing main body 18 is connected to the end of the motor housing 13 opposite the discharge housing 12. The connector connection portion 19 protrudes radially outward from a portion of the outer circumferential surface of the housing main body 18.

[0020] <High-voltage connector> The electric compressor 10 includes a high-voltage connector 20. The high-voltage connector 20 is provided in the inverter housing 14. Therefore, the high-voltage connector 20 is provided in the housing 11. The high-voltage connector 20 is provided on a surface of the connector connection portion 19 that faces the motor housing 13. The high-voltage connector 20 protrudes from the surface of the connector connection portion 19 that faces the motor housing 13. The high-voltage connector 20 is electrically connected to the inverter 17.

[0021] A high-voltage harness 21 is connected to the high-voltage connector 20. The high-voltage connector 20 is configured to be detachable from the high-voltage harness 21. When the high-voltage harness 21 is connected to the high-voltage connector 20, high-voltage DC power from the vehicle-side high-voltage battery is supplied to the inverter 17 via the high-voltage harness 21 and the high-voltage connector 20.

[0022] <Low voltage connector> The electric compressor 10 is equipped with a low-voltage connector 22. The low-voltage connector 22 is provided in the inverter housing 14. Therefore, the low-voltage connector 22 is provided in the housing 11. The low-voltage connector 22 is provided on a surface of the connector connection portion 19 that faces the motor housing 13. The low-voltage connector 22 protrudes from the surface of the connector connection portion 19 that faces the motor housing 13. When the connector connection portion 19 is viewed from the axial direction of the housing 11, the high-voltage connector 20 and the low-voltage connector 22 are arranged side by side with respect to the connector connection portion 19. The low-voltage connector 22 is electrically connected to the inverter 17.

[0023] A low-voltage harness 23 is connected to the low-voltage connector 22. The low-voltage connector 22 is configured to be detachable from the low-voltage harness 23. When the low-voltage harness 23 is connected to the low-voltage connector 22, low-voltage power from the vehicle-side low-voltage battery is supplied to the inverter 17 via the low-voltage harness 23 and the low-voltage connector 22. When the low-voltage harness 23 is connected to the low-voltage connector 22, a control signal from a vehicle ECU, which is a host ECU, is input to the inverter 17 via the low-voltage harness 23 and the low-voltage connector 22.

[0024] <Inverter operation> The inverter 17 includes, for example, a switching element that performs a switching operation to drive the motor 16, a filter element that reduces noise, etc. The inverter 17 also includes, for example, a control circuit that controls the switching operation of the switching element.

[0025] The inverter 17 is driven by power from the vehicle's low-voltage battery. The inverter 17 controls the switching operation of the switching elements based on control signals from the vehicle ECU. This causes the inverter 17 to be driven based on control signals from the vehicle ECU. The inverter 17 converts DC power from the vehicle's high-voltage battery into AC power through the switching operation of the switching elements. The AC power is then supplied to the motor 16, thereby driving the motor 16. In this way, the inverter 17 converts DC power into AC power and supplies it to the motor 16, thereby driving the motor 16.

[0026] <Mounting feet> The housing 11 is provided with mounting feet 24. The mounting feet 24 protrude from the outer peripheral surface of the discharge housing 12, for example. The mounting feet 24 are shaped like a rectangular tube. The inside of the mounting feet 24 is formed with bolt insertion holes 25 through which fixing bolts (not shown) can be inserted. The mounting feet 24 protrude from the outer peripheral surface of the discharge housing 12 so that, when viewed from the axial direction of the housing 11, the axial direction of the bolt insertion holes 25 is perpendicular to the axial direction of the housing 11. The electric compressor 10 is fixed to a target part on the vehicle side by threading a fixing bolt passing through the bolt insertion holes 25 of the mounting feet 24 into the target part on the vehicle side.

[0027] As shown in Figures 3 and 4, a base 26 protrudes from the surface of the mounting foot 24 opposite the housing 11 and closer to the motor housing 13. The base 26 is in the shape of a flat rectangular block. An internally threaded hole 27 is formed in the surface of the base 26 opposite the housing 11. The internally threaded hole 27 passes through the base 26 from the surface of the base 26 opposite the housing 11 to the inside of the mounting foot 24. The internally threaded hole 27 is positioned so as not to overlap with the bolt insertion hole 25 of the mounting foot 24 in the radial direction of the housing 11. The internally threaded hole 27 is formed in a position relative to the base 26 and the mounting foot 24 so as not to interfere with the bolt insertion hole 25.

[0028] <Bracket Overview> The electric compressor 10 includes a bracket 30. The bracket 30 is fixed to the housing 11. A high-pressure harness 21 connected to the high-pressure connector 20 and a low-pressure harness 23 connected to the low-pressure connector 22 are supported by the housing 11 via the bracket 30. The bracket 30 includes a fixing plate portion 31, a first mounting plate portion 41, and a second mounting plate portion 51. The bracket 30 is formed by pressing a single flat plate.

[0029] <Fixed plate part> 4, the fixing plate 31 has a first plate 32 and a second plate 33. In a plan view, the first plate 32 is a generally elongated plate. The fixing plate 31 is disposed relative to the mounting foot 24 with the longitudinal direction of the first plate 32 aligned with the axial direction of the bolt insertion hole 25 of the mounting foot 24.

[0030] A through hole 34 is formed in the first plate portion 32. The through hole 34 penetrates the first plate portion 32 in the thickness direction of the first plate portion 32. The fixing plate portion 31 is fixed to the base 26 by a bolt 35 passing through the through hole 34 and screwed into the female threaded hole 27 of the base 26. Therefore, the fixing plate portion 31 is fixed to the housing 11.

[0031] The second plate portion 33 extends from one side in the short direction of the first plate portion 32. The second plate portion 33 is continuous with one end of the first plate portion 32 in the long direction. When viewed from above, the second plate portion 33 has a generally elongated plate shape. The long direction of the second plate portion 33 is aligned perpendicular to the long direction of the first plate portion 32. The second plate portion 33 extends from one side in the short direction of the first plate portion 32 on the same plane as the first plate portion 32. The boundary between the first plate portion 32 and the second plate portion 33 is indicated by a two-dot chain line L1 in FIG. 4.

[0032] <Fixed plate rib> The fixing plate 31 has all sides bent in the same direction except for an end portion located opposite the second plate 33 in the longitudinal direction of the first plate 32. In this way, the bracket 30 has fixing plate ribs 36 formed by bending the sides of the fixing plate 31. The fixing plate 31 is fixed to the housing 11 so that the tips of the fixing plate ribs 36 face the housing 11. Therefore, the fixing plate ribs 36 are formed by bending the sides of the fixing plate 31 so that the tips of the fixing plate ribs 36 face the housing 11. In the following description, the end of the second plate 33 located opposite the first plate 32 may be referred to as the "first end 31a of the fixing plate 31." Furthermore, the end of the first plate 32 located opposite the second plate 33 may be referred to as the "second end 31b of the fixing plate 31."

[0033] <First mounting plate part> As shown in FIGS. 5 and 6 , the first mounting plate 41 has a connecting portion 42 and an extending portion 43. The connecting portion 42 is generally elongated and plate-shaped. One longitudinal end of the connecting portion 42 is continuous with an end of the second plate 33 located on the opposite side from the first plate 32. The connecting portion 42 is bent from the end of the second plate 33 located on the opposite side from the first plate 32. Therefore, the first mounting plate 41 is bent from the first end 31 a of the fixing plate 31. The connecting portion 42 is bent from the first end 31 a of the fixing plate 31 and extends in a direction perpendicular to the fixing plate 31. The bending direction of the first mounting plate 41 with respect to the first end 31 a of the fixing plate 31 is opposite to the bending direction of the fixing plate rib 36. The bracket 30 is disposed relative to the housing 11 so that the bending direction of the first mounting plate portion 41 relative to the first end 31a of the fixing plate portion 31 faces away from the housing 11. In this manner, the first mounting plate portion 41 is bent from the first end 31a of the fixing plate portion 31 and extends away from the housing 11. The boundary between the fixing plate portion 31 and the first mounting plate portion 41 is indicated by a two-dot chain line L2 in Figures 4 and 5.

[0034] The extending portion 43 extends from a side portion located in the short-side direction of the connecting portion 42. The extending portion 43 has a generally elongated plate shape. The longitudinal direction of the extending portion 43 coincides with the short-side direction of the connecting portion 42. The extending portion 43 is located on the same plane as the connecting portion 42.

[0035] <First mounting plate rib> 6, the side of the connecting portion 42 opposite the extending portion 43 is bent away from the fixing plate portion 31. In this way, the bracket 30 has a first fixing plate portion rib 44 formed by bending the side of the first fixing plate portion 41. The first fixing plate portion rib 44 is continuous with the fixing plate portion rib 36.

[0036] <First locking hole> 4 and 5, a first locking hole 45 is formed in the extension portion 43. Therefore, the first mounting plate portion 41 has the first locking hole 45. The first locking hole 45 is formed in an end portion of the extension portion 43 located on the opposite side from the connection portion 42. The first locking hole 45 penetrates the extension portion 43 in the thickness direction of the extension portion 43. The first locking hole 45 is configured to be able to lock a first retaining clip 61 that holds the high-voltage harness 21.

[0037] <Second mounting plate> As shown in FIG. 4, the second mounting plate 51 is generally elongated and plate-shaped. The second mounting plate 51 is continuous with the other longitudinal end of the connecting portion 42. The second mounting plate 51 is continuous with the end of the connecting portion 42 located on the opposite side from the fixing plate 31. The second mounting plate 51 is bent from the end of the connecting portion 42 located on the opposite side from the fixing plate 31 and extends toward the second end 31b of the fixing plate 31. Therefore, the second mounting plate 51 is bent from the first mounting plate 41 and extends toward the second end 31b of the fixing plate 31. The boundary between the first mounting plate 41 and the second mounting plate 51 is indicated by a two-dot chain line L3 in FIGS. 5 and 6.

[0038] 2, the connection portion 42 connects the fixed plate portion 31 and the second mounting plate portion 51 and is disposed in a position facing the high-voltage connector 20. The extension portion 43 extends from the connection portion 42 in a direction away from each of the fixed plate portion 31 and the second mounting plate portion 51.

[0039] <Second locking hole> 4, 5, and 6, the second mounting plate 51 has a second locking hole 52. The second locking hole 52 penetrates the second mounting plate 51 in the thickness direction of the second mounting plate 51. The second locking hole 52 is configured to be able to lock a second retaining clip 71 that holds the low-voltage harness 23.

[0040] <First retaining clip> 4, the first retaining clip 61 has a binding portion 62 and a snap-fit portion 63. The binding portion 62 and the snap-fit portion 63 are integrated with each other. The binding portion 62 is a binding band configured to be able to bind the high-voltage harness 21. The first retaining clip 61 holds the high-voltage harness 21 by binding the high-voltage harness 21 with the binding portion 62.

[0041] The snap-fit portion 63 has a plurality of elastically deformable locking pieces 63a. The locking pieces 63a are hook-shaped. The snap-fit portion 63 is generally umbrella-shaped. The snap-fit portion 63 can be forcibly passed through the inside of the first locking hole 45. When the snap-fit portion 63 passes through the inside of the first locking hole 45, each locking piece 63a is elastically deformed, and when the snap-fit portion 63 passes through the first locking hole 45, each locking piece 63a returns to its original shape before elastic deformation. As a result, each locking piece 63a is locked around the first locking hole 45 in the extension portion 43.

[0042] 2, 3, and 4, the first locking hole 45 locks the first retaining clip 61 so that the high-voltage harness 21 is disposed on the surface of the first mounting plate 41 that is located on the opposite side from the fixing plate 31. Specifically, the first locking hole 45 locks the first retaining clip 61 so that the high-voltage harness 21 is disposed relative to the first mounting plate 41 in a bent state so that it extends from the high-voltage connector 20 toward the connection portion 42 and extends along the extension portion 43. In this manner, the high-voltage harness 21 is attached to the first mounting plate 41.

[0043] <Second retaining clip> 4, the second retaining clip 71 has a binding portion 72 and a snap-fit portion 73. The binding portion 72 and the snap-fit portion 73 are integrated with each other. The binding portion 72 is a cable tie configured to be able to bind the low-voltage harness 23. The second retaining clip 71 holds the low-voltage harness 23 by binding the low-voltage harness 23 with the binding portion 72.

[0044] The snap-fit portion 73 has a plurality of elastically deformable locking pieces 73a. The locking pieces 73a are hook-shaped. The snap-fit portion 73 is generally umbrella-shaped. The snap-fit portion 73 can be forcibly passed through the inside of the second locking hole 52. When the snap-fit portion 73 passes through the inside of the second locking hole 52, each locking piece 73a elastically deforms, and when the snap-fit portion 73 passes through the second locking hole 52, each locking piece 73a returns to its original shape before elastic deformation. As a result, each locking piece 73a is locked around the second locking hole 52 in the second mounting plate portion 51.

[0045] 2, 3, and 4, the second locking hole 52 locks the second retaining clip 71 so that the low-voltage harness 23 is disposed on the surface of the second mounting plate 51 that is located on the opposite side from the fixing plate 31. In this manner, the low-voltage harness 23 is attached to the second mounting plate 51.

[0046] <Reinforcing rib> 5 and 6, the bracket 30 has a reinforcing rib 46. The reinforcing rib 46 is formed by recessing a portion of the bent portion of the first mounting plate portion 41 relative to the fixing plate portion 31. Specifically, the reinforcing rib 46 is formed by recessing a surface of the first mounting plate portion 41 located on the opposite side from the fixing plate portion 31 toward the second mounting plate portion 51 in a portion of the bent portion of the first mounting plate portion 41 relative to the fixing plate portion 31.

[0047] [Operation of the embodiment] Next, the operation of this embodiment will be described. The first mounting plate 41 is bent from the first end 31a of the fixing plate 31 and extends away from the housing 11. The second mounting plate 51 is bent from the first mounting plate 41 and extends toward the second end 31b of the fixing plate 31. Therefore, the strength of the second mounting plate 51 is easily ensured by the fixing plate 31 and the first mounting plate 41. Furthermore, because the fixing plate 31 and the second mounting plate 51 are bent from the first mounting plate 41, the fixing plate 31 and the second mounting plate 51 function as ribs for the first mounting plate 41. As a result, the strength of the first mounting plate 41 is easily ensured.

[0048] Furthermore, the strength of the fixing plate 31 is improved by the fixing plate ribs 36, which makes it easier to ensure the strength of each of the first mounting plate 41 and the second mounting plate 51. The strength of the first mounting plate 41 is improved by the first mounting plate ribs 44, which makes it easier to ensure the strength of each of the first mounting plate 41 and the second mounting plate 51. The strength of the bending portion of the first mounting plate 41 relative to the fixing plate 31 is improved by the reinforcing ribs 46, which makes it easier to ensure the strength of the first mounting plate 41.

[0049] Therefore, the low-voltage harness 23 is stably supported by the housing 11 via the bracket 30, and the high-voltage harness 21, which is heavier than the low-voltage harness 23, is also stably supported by the housing 11 via the bracket 30.

[0050] [Effects of the embodiment] The above embodiment can provide the following effects. (1) The first mounting plate 41 is bent from the first end 31a of the fixing plate 31 and extends away from the housing 11. The second mounting plate 51 is bent from the first mounting plate 41 and extends toward the second end 31b of the fixing plate 31. This configuration makes it easier for the fixing plate 31 and the first mounting plate 41 to ensure the strength of the second mounting plate 51. Therefore, the low-voltage harness 23 can be stably supported on the housing 11 via the bracket 30. Furthermore, because the fixing plate 31 and the second mounting plate 51 are bent from the first mounting plate 41, the fixing plate 31 and the second mounting plate 51 function as ribs for the first mounting plate 41. As a result, the strength of the first mounting plate 41 is easily ensured. Therefore, the high-voltage harness 21, which is heavier than the low-voltage harness 23, can be stably supported on the housing 11 via the bracket 30. As a result, the high-voltage harness 21 and the low-voltage harness 23 can be stably supported on the housing 11 via the bracket 30.

[0051] (2) The high-voltage harness 21 can be attached to the first mounting plate 41 simply by engaging the first retaining clip 61 with the first locking hole 45. The low-voltage harness 23 can be attached to the second mounting plate 51 simply by engaging the second retaining clip 71 with the second locking hole 52. The high-voltage harness 21 is arranged on the surface of the first mounting plate 41 opposite the fixing plate 31, and the low-voltage harness 23 is arranged on the surface of the second mounting plate 51 opposite the fixing plate 31. Therefore, the high-voltage harness 21 and the low-voltage harness 23 can be stably supported on the housing 11 via the bracket 30 without interfering with each other.

[0052] (3) The first locking hole 45 is formed in the extension portion 43. This allows the distance between the high-voltage connector 20 and the first locking hole 45 to be longer than when the first locking hole 45 is formed in the connection portion 42, for example. Therefore, the high-voltage harness 21 can be disposed on the first mounting plate portion 41 in a bent state so as to extend from the high-voltage connector 20 toward the connection portion 42 and extend along the extension portion 43, making it easier to lock the first retaining clip 61 into the first locking hole 45. This allows the high-voltage harness 21 to be easily handled.

[0053] (4) The bracket 30 has the fixing plate ribs 36 formed by bending the sides of the fixing plate 31. This allows the fixing plate ribs 36 to improve the strength of the fixing plate 31. As a result, the strength of each of the first mounting plate 41 and the second mounting plate 51 can be more easily ensured. Therefore, the high-voltage harness 21 and the low-voltage harness 23 can be more stably supported on the housing 11 via the bracket 30.

[0054] (5) The bracket 30 has first mounting plate ribs 44 formed by bending the sides of the first mounting plate 41. This allows the first mounting plate ribs 44 to improve the strength of the first mounting plate 41. As a result, the strength of each of the first mounting plate 41 and the second mounting plate 51 can be more easily ensured. Therefore, the high-voltage harness 21 and the low-voltage harness 23 can be more stably supported on the housing 11 via the bracket 30.

[0055] (6) The bracket 30 has a reinforcing rib 46 formed by recessing a portion of the first mounting plate 41 where it bends relative to the fixed plate 31. This allows the reinforcing rib 46 to improve the strength of the first mounting plate 41 where it bends relative to the fixed plate 31. As a result, the strength of the first mounting plate 41 is more easily ensured. Therefore, the high-voltage harness 21 and the low-voltage harness 23 can be more stably supported on the housing 11 via the bracket 30.

[0056] [Example of change] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0057] In the above embodiment, for example, the high-voltage harness 21 may be attached to the first mounting plate portion 41 by directly wrapping a cable tie around the first locking hole 45 .

[0058] In the above embodiment, for example, the low-voltage harness 23 may be attached to the second mounting plate portion 51 by directly wrapping a cable tie around the second fastening hole 52 .

[0059] In the above-described embodiment, the first attachment plate portion 41 may not have the extending portion 43. In this case, the first locking hole is formed in the connecting portion 42, for example. In the embodiment, the high-voltage harness 21 does not have to be bent and arranged relative to the first mounting plate 41 so as to extend along the extending portion 43. In this case, the first mounting plate 41 does not have the extending portion 43, and the first locking hole 45 is formed, for example, in the connection portion 42. The first locking hole 45 may lock the first retaining clip 61 so that the high-voltage harness 21 is arranged relative to the first mounting plate 41 so as to extend from the high-voltage connector 20 toward the connection portion 42 and bent and extend in the longitudinal direction of the connection portion 42.

[0060] In the above embodiment, the fixing plate ribs 36 may be formed by bending the sides of the fixing plate 31 so that the tips of the fixing plate ribs 36 face away from the housing 11 .

[0061] In the above embodiment, the bracket 30 may not have the fixing plate portion rib 36 . In the above embodiment, the first mounting plate rib 44 does not have to be continuous with the fixing plate rib 36 .

[0062] In the above embodiment, the first mounting plate rib 44 may be formed by bending the side of the connecting portion 42 opposite the extending portion 43 toward the fixing plate 31 side.

[0063] In the above embodiment, the bracket 30 may not have the first mounting plate portion rib 44. In an embodiment, the reinforcing rib 46 may be formed by recessing the surface of the first mounting plate portion 41 facing the fixing plate portion 31 toward the opposite side to the second mounting plate portion 51 in a portion of the bent portion of the first mounting plate portion 41 relative to the fixing plate portion 31.

[0064] In the above embodiment, the bracket 30 may not have the reinforcing rib 46 . In the above embodiment, the fixing plate 31 is fixed to the base 26, but this is not limitative. The key is that the fixing plate 31 only needs to be fixed to the housing 11, and the fixing position of the fixing plate 31 relative to the housing 11 is not particularly limited.

[0065] In the embodiment, the electric compressor 10 may be configured such that, for example, the inverter 17 is disposed radially outward of the housing 11. In other words, the compression unit 15, the motor 16, and the inverter 17 do not have to be disposed side by side in this order in the axial direction of the housing 11.

[0066] In the above-described embodiment, the compression unit 15 is not limited to a scroll type, but may be, for example, a piston type or a vane type. In the above embodiment, the electric compressor 10 constitutes a vehicle air conditioning system. However, the present invention is not limited to this. For example, the electric compressor 10 may be mounted on a fuel cell vehicle and may compress air, which serves as a fluid to be supplied to the fuel cell, using the compression unit 15.
