[0009] Fig. 1 is a configuration diagram of a power system 12 including a power supply device 10 (power device, holding structure, holding body, etc.). The power system 12 includes the power supply device 10 and a vehicle 14 (another power device). In the following explanation, the right side of the paper in Fig. 1 is defined as the front direction, the left side as the rear direction, the top side as the upward direction, and the bottom side as the downward direction, and the front-rear, up-down, and left-right directions of the power supply device 10 will be explained.

[0010] The power supply device 10 is a portable power device. The power supply device 10 includes a device body 16, a cable 18 (power line), and a connector 20 (power terminal). The device body 16 includes a housing 22, a front cover 24, and a rear cover 26 (lid member).

[0011] The housing 22 accommodates various components that constitute the power supply device 10. The front cover 24 is attached to a front wall 28 of the housing 22. The front cover 24 is rotatable forward relative to the front wall 28 around a rotation shaft portion 30 provided on the front wall 28.

[0012] A plurality of switches and a plurality of output terminals (not shown) are provided on the front wall 28 of the housing 22. A user can issue various instructions to the power supply device 10 by operating each switch. In addition, the plurality of output terminals can output power from the power supply device 10 to the outside. The power supply device 10 can output, for example, single-phase AC power (single-phase AC power) and three-phase AC power (three-phase AC power).

[0013] The cable 18 extends from the device body 16. In detail, as shown in FIG. 2 and FIG. 3, a communication hole 48 is provided in a rear wall 46 (fixing surface) of the device body 16. The rear wall 46 is formed in a rectangular shape when viewed from the back of the device body 16. The communication hole 48 communicates the inside and outside of the device body 16. The cable 18 extends from the inside of the device body 16 to the outside of the device body 16 through the communication hole 48. The communication hole 48 and the base end of the cable 18 are covered with a grommet 50 (covering portion). A connector 20 is provided at the tip (tip) of the cable 18. The connector 20 is a male connector. The male connector is also called a plug. The cable 18 is drawn out from the device body 16 to the outside through the communication hole 48. Therefore, the end of the cable 18 covered by the grommet 50 is actually the end of the portion of the cable 18 that is exposed to the outside through the rear wall 46 of the device body 16 .

[0014] The rear wall 46 of the housing 22 is provided with a cable housing portion 52 (power line housing portion), a connector holding portion 54 (holding portion), and a first support portion 56.

[0015] The cable housing portion 52 houses the cable 18. The cable housing portion 52 has an outer peripheral wall 58 and an inner peripheral wall 60. The outer peripheral wall 58 is an arc-shaped wall portion that protrudes rearward from the rear wall 46. The inner peripheral wall 60 is provided on the rear wall 46 on the inside of the outer peripheral wall 58. The inner peripheral wall 60 is an arc-shaped wall portion that protrudes rearward from the rear wall 46.

[0016] As described above, the base end of the cable 18 is located at the upper part of the rear wall 46. The cable housing 52 houses the cable 18 between the inner circumferential wall 60 and the outer circumferential wall 58 by winding the cable 18 between the inner circumferential wall 60 and the outer circumferential wall 58 a plurality of times.

[0017] The connector holding portion 54 is fixed to the rear wall 46. More specifically, the connector holding portion 54 is made of a resin material. The connector holding portion 54 has a main portion 62 and a fixing portion 64.

[0018] 2 and 3, the fixing portion 64 is disposed on the outer side of the cable housing portion 52 in the rear wall 46. The fixing portion 64 is disposed on the outer edge side of the rear wall 46. Specifically, the fixing portion 64 is disposed along one side 66 extending in the up-down direction (vertical direction) of the rear wall 46. Therefore, the fixing portion 64 extends in the up-down direction.

[0019] As shown in FIG. 4, the fixing portion 64 is fixed to the housing 22 by two metal bolts 68, 69 (fixing devices). More specifically, a recess 250 recessed forward is provided at a location on the side 66 side of the rear wall 46. Two protrusions 252 protrude forward from the bottom of the recess 250. The two protrusions 252 are cylindrical protrusions. The two protrusions 252 are provided at the bottom of the recess 250 with a gap between them in the up-down direction. The housing 22 has a metal frame 256. The two protrusions 252 protrude to the vicinity of the frame 256 of the housing 22.

[0020] As shown in FIGS. 2 to 4, the fixing portion 64 has a fixing portion main body 260. The fixing portion main body 260 is a block extending in the vertical direction. The fixing portion main body 260 is disposed in the recess 250 of the rear wall 46. The front surface of the fixing portion main body 260 contacts the bottom of the recess 250.

[0021] Two protrusions 262, 264 protrude forward from the front surface of the fixing part main body 260. The two protrusions 262, 264 have the same shape and size. The two protrusions 262, 264 are provided on the front surface of the fixing part main body 260 with a gap therebetween in the up-down direction. The protrusion 262 is an upper protrusion. The protrusion 264 is a lower protrusion. The length (protrusion length) of the two protrusions 262, 264 in the front-rear direction (second direction) is shorter than the length (plate thickness) of the fixing part main body 260 in the front-rear direction. In other words, the thickness of the fixing part main body 260 is greater than the length of the protrusions 262, 264.

[0022] The two protrusions 262, 264 are cylindrical protrusions. Therefore, an insertion hole 266 extending in the front-rear direction (second direction) is formed on the inside of the protrusion 262. An insertion hole 268 extending in the front-rear direction is formed on the inside of the protrusion 264. The two insertion holes 266, 268 have the same shape and size.

[0023] The two protrusions 262, 264 are inserted inside the two protrusions 252. By inserting the two protrusions 262, 264 into the two protrusions 252, the fixing portion main body 260 is disposed in the recess 250 of the rear wall 46.

[0024] Two fastener holes 270, 272 are formed in the fixing part main body 260. The two fastener holes 270, 272 have approximately the same shape and size. The two fastener holes 270, 272 are formed in the fixing part main body 260 with a gap therebetween in the up-down direction. The fastener hole 270 is an upper fastener hole. The fastener hole 272 is a lower fastener hole. The two fastener holes 270, 272 extend in the front-rear direction. The upper fastener hole 270 communicates with the insertion hole 266. The fastener hole 270 is formed coaxially with the insertion hole 266. The lower fastener hole 272 communicates with the insertion hole 268. The fastener hole 272 is formed coaxially with the insertion hole 268.

[0025] Fastener hole 272 is formed near main portion 62. Fastener hole 272 is formed near the connecting portion between fixing portion 64 and main portion 62. Main portion 62 protrudes from fixing portion 64. Therefore, part of fastener hole 272 extends to the connecting portion between fixing portion 64 and main portion 62. That is, the shape of fastener hole 272 is slightly different from the shape of fastener hole 270. However, in fastener hole 272, the depth dimension (tool path) when tool 290 is inserted is the same as the depth dimension (insertion depth) when tool 290 is inserted in fastener hole 270.

[0026] As described above, since the thickness of the fixing portion main body 260 is greater than the length of the two protrusions 262,264, the length of the two fixing tool holes 270,272 in the front-rear direction is greater than the length of the two insertion holes 266,268.

[0027] The inner diameter of the two fastener holes 270, 272 is larger than the inner diameter of the two insertion holes 266, 268. Therefore, in the fixed portion 64, the connection portions between the two fastener holes 270, 272 and the two insertion holes 266, 268 form steps. The two insertion holes 266, 268 are formed penetrating bottoms 271, 273 (abutment portions) of the two fastener holes 270, 272.

[0028] Two metal nuts 274, 276 are attached to the frame 256. The two nuts 274, 276 are crimped to the frame 256. The two nuts 274, 276 have the same shape and size. The nut 274 is attached to the frame 256 coaxially with the upper insertion hole 266. The nut 276 is attached to the frame 256 coaxially with the lower insertion hole 268.

[0029] A collar 278 (reinforcing portion) is inserted into the upper insertion hole 266. A collar 280 (reinforcing portion) is inserted into the lower insertion hole 268. The collars 278, 280 have the same shape and size. That is, the collars 278, 280 are the same type of collars. The collars 278, 280 are cylindrical members made of metal. The collars 278, 280 are made of a metal material that has at least one of strength and rigidity greater than that of the connector holding portion 54.

[0030] The fixing portion 64 is fixed to the housing 22 by two bolts 68, 69 screwed into nuts 274, 276. The two bolts 68, 69 have the same shape and size. That is, the two bolts 68, 69 are the same type of bolt. The bolt 68 has a threaded portion 282 (small diameter portion) and a head 284 (large diameter portion). The bolt 69 has a threaded portion 286 (small diameter portion) and a head 288 (large diameter portion). The outer diameters of the heads 284, 288 are larger than the outer diameters of the threaded portions 282, 286.

[0031] The outer diameter of the threaded portions 282, 286 is smaller than the inner diameter of the insertion holes 266, 268 and the collars 278, 280. The outer diameter of the heads 284, 288 is larger than the outer diameter of the insertion holes 266, 268 and the collars 278, 280. The outer diameter of the heads 284, 288 is also smaller than the inner diameter of the fastener holes 270, 272.

[0032] When the fixing portion 64 is fixed to the frame 256 of the housing 22, the bolt 68 is inserted into the fastener hole 270. The screw portion 282 is inserted through the insertion hole 266 and the collar 278. In this state, a tool 290 such as a hexagonal wrench is inserted into the fastener hole 270, and the head 284 is turned, so that the screw portion 282 and the nut 274 are screwed together. The head 284 abuts against the bottom 271 of the fastener hole 270, and the tip surface of the protruding portion 262 abuts against the nut 274, so that the bolt 68 fixes the fixing portion 64 to the frame 256. A washer 292 may be inserted between the head 284 and the bottom 271 of the bolt 68. This allows the fixing portion 64 to be effectively fixed to the frame 256 by the bolt 68.

[0033] Similarly, the bolt 69 is inserted into the fastener hole 272. The screw portion 286 passes through the insertion hole 268 and the collar 280. In this state, the tool 290 is inserted into the fastener hole 272, and the head 288 is turned, whereby the screw portion 286 and the nut 276 are screwed together. The head 288 abuts against the bottom 273 of the fastener hole 272, and the tip surface of the protruding portion 264 abuts against the nut 276, whereby the bolt 69 fixes the fixing portion 64 to the frame 256. Note that a washer 294 may be interposed between the head 288 and the bottom 273 of the bolt 69. This allows the fixing portion 64 to be effectively fixed to the frame 256 by the bolt 69.

[0034] The main portion 62 is connected to a lower end of the fixing portion 64. The main portion 62 and the fixing portion 64 are integrally formed. The main portion 62 holds the connector 20.

[0035] More specifically, the main portion 62 is connected to the lower end portion of the fixed portion main body 260. The lower fastener hole 272 is formed in a location on the lower end side of the fixed portion main body 260. Therefore, in the fixed portion main body 260, an outer periphery 296 that forms the fastener hole 272 is formed integrally with an outer periphery 298 (annular portion) of the main portion 62. The outer periphery 298 of the main portion 62 is formed in an annular shape.

[0036] The main part 62 is a cylindrical part with a bottom. A fitting recess 70 that fits with the connector 20 is formed on the inside of the outer periphery 298 of the main part 62. The fitting recess 70 opens toward the cable housing part 52. As shown in FIG. 7, communication holes 300, 302 that communicate with the outside are formed on the bottom of the fitting recess 70. The communication holes 300, 302 function as drainage holes for discharging liquid such as rainwater from the fitting recess 70 to the outside. In addition, a locking groove 304 that is recessed radially outward of the main part 62 is formed on the inner wall of the outer periphery 298 that forms the fitting recess 70. The locking groove 304 is a linear recess that is recessed radially outward from the fitting recess 70. The locking groove 304 is formed along the axial direction of the main part 62. The locking groove 304 communicates with the communication hole 300. By forming the locking groove 304, a step portion 306 (locking portion) is formed on the inner wall of the outer circumferential portion 298. The communication hole 300, the locking groove 304, and the step portion 306 are formed continuously along the axial direction of the main portion 62.

[0037] In the main portion 62, an opening end surface 72 (tip surface) where the fitting recess 70 opens is flat. In this case, the direction in which the connector 20 is inserted into and removed from the main portion 62 (first direction) and the direction in which the fixing portion 64 is fixed by the bolts 68, 69 (second direction) are mutually intersecting. That is, the first direction is an oblique direction when viewed from behind in Figures 2 and 3. The second direction is the front-rear direction as described above.

[0038] As shown in FIG. 2 and FIG. 3, the connector 20 has a grip 74 (holding portion), a connector body 76 (terminal body), and a fitting portion 78. The grip 74 is a handle that can be held by a user. The grip 74 is connected to a base end portion of the connector body 76. A tip surface 80 of the connector body 76 is flat. The fitting portion 78 is a tubular portion protruding from the tip surface 80 of the connector body 76. The fitting portion 78 is a tip portion of the connector 20. The fitting portion 78 fits into a fitting recess 70 formed in the main portion 62 of the connector holding portion 54. That is, in a state in which the cable 18 is accommodated in the cable accommodating portion 52, the fitting portion 78 of the connector 20 fits into the fitting recess 70, and the tip surface 80 of the connector body 76 abuts against the open end surface 72 of the main portion 62, whereby the connector 20 is held in the connector holding portion 54 (main portion 62).

[0039] As described above, since the main portion 62 is inclined in an oblique direction, when the connector 20 is held by the main portion 62, the base end (the end on the cable 18 side) of the connector 20 faces the corner portion 308 of the other side 307 facing the side 66 of the rear wall 46. Furthermore, when the connector 20 is held by the main portion 62, the connector 20 does not overlap the base end of the cable 18 and the grommet 50. Note that, as described above, the end of the cable 18 covered by the grommet 50 is the end of the part of the cable 18 that is exposed to the outside from the rear wall 46 of the device main body 16. Therefore, in reality, the end of the part of the cable 18 that is exposed to the outside and the grommet 50 do not overlap with the connector 20. Furthermore, when the connector 20 is held by the main portion 62 and the rear cover 26 covers a part of the rear wall 46, the mating portion (the opening end surface 72 and the tip surface 80) of the main portion 62 and the connector 20 is visible from the outside.

[0040] As shown in FIG. 1, when the rear cover 26 is closed, the connector holding portion 54 including the main portion 62 cannot be seen from the outside in a side view. When the rear cover 26 is closed, the communication holes 300, 302 cannot be seen from the outside. When the rear cover 26 is opened relative to the rear wall 46, the connector holding portion 54 including the main portion 62 can be seen from the outside. When the rear cover 26 is opened, the communication holes 300, 302 can be seen from the outside. In other words, the main portion 62 and the communication holes 300, 302 are provided at positions that are visible from the outside when the rear cover 26 is opened and are covered by the rear cover 26 when the rear cover 26 is closed. This makes it possible to prevent foreign matter from entering the inside of the connector holding portion 54.

[0041] 2 and 3, the first support portion 56 is provided at the upper end of the fixing portion 64. The first support portion 56 is a recess 310 onto which a portion of the cable 18 can be hooked. Therefore, the size of the recess 310 constituting the first support portion 56 is larger than the outer diameter of the cable 18. In a state in which the user removes the connector 20 from the main portion 62 and pulls out the cable 18 from the cable housing portion 52, the user hooks a portion of the cable 18 between the base end and the tip end of the cable 18 onto the first support portion 56.

[0042] A second support portion 82 is provided on the rear wall 46 so as to be adjacent to the first support portion 56. The second support portion 82 supports a portion of the cable 18 when the portion of the cable 18 is supported by the first support portion 56.

[0043] The rear cover 26 is rotatable relative to the rear wall 46 around a rotation shaft 84 provided on the rear wall 46. The rear cover 26 is provided with a surrounding portion 86 that surrounds a portion of the cable 18 when the rear cover 26 covers a portion of the rear wall 46 in a state in which a portion of the cable 18 is supported by the first support portion 56 and the second support portion 82. The surrounding portion 86 is a recess formed in a side portion of the rear cover 26.

[0044] As shown in FIGS. 1 to 6, the connector 20 further includes a release button 90 (input portion) and a latch portion 92. As shown in FIG.

[0045] The release button 90 is provided at the connecting portion between the connector body 76 and the grip 74. A part of the release button 90 protrudes to the outside from the connector 20. The latch portion 92 is a rod-shaped member (not shown). An engagement claw 104 (engagement portion) is formed at the tip of the latch portion 92. The engagement claw 104 is capable of protruding radially outward from the fitting portion 78. The latch portion 92 is capable of rotating around a rotation shaft portion (not shown) provided in the connector body 76.

[0046] The connector 20 is connected to a connector 120 (another power terminal) provided on the vehicle 14. That is, the connector 20 is detachable from the connector 120. In this case, detachable includes both a case in which the connector 20 can be attached to the connector 120 and a case in which the connector 20 can be detached from the connector 120.

[0047] Specifically, the connector 120 is a female connector that is connected to the connector 20, which is a male connector. A female connector is also called a receptacle. The connector 120 has a mounting recess 122 (fitting opening) into which the fitting portion 78 of the connector 20 is attached. The mounting recess 122 is provided with an engagement recess 124 (engaged portion) that is recessed radially outward. When a user inserts the fitting portion 78 of the connector 20 into the mounting recess 122, the engagement claw 104 of the latch portion 92 engages with the engagement recess 124. As a result, the connector 20 of the power supply device 10 is attached to the connector 120 of the vehicle 14.

[0048] Furthermore, when the user presses the release button 90, the latch portion 92 rotates about the rotation shaft portion. At this time, the engagement claw 104 moves away from the engagement recess 124 and retracts into the fitting portion 78. This releases the engagement between the engagement claw 104 and the engagement recess 124. The user can remove the connector 20 of the power supply device 10 from the connector 120 of the vehicle 14 by pulling the connector 20 while pressing the release button 90.

[0049] When the connector 20 is held by the main part 62, the engagement claw 104 is engaged with the stepped portion 306. When the user presses the release button 90 in this state, the latch portion 92 rotates about the rotating shaft portion, and the engagement claw 104 retracts into the fitting portion 78. This releases the engagement between the engagement claw 104 and the stepped portion 306. The user can remove the connector 20 from the main part 62 by pulling the connector 20 while pressing the release button 90.

[0050] 1, the vehicle 14 has a battery (not shown). Examples of the vehicle 14 include various vehicles such as a one-wheeled vehicle, a two-wheeled vehicle, a three-wheeled vehicle, and a four-wheeled vehicle equipped with a battery and a connector 120. Examples of the vehicle 14 include various vehicles such as an electric vehicle (electric automobile) and a hybrid vehicle equipped with a battery and a connector 120.

[0051] Next, the operation of the power supply device 10 according to this embodiment will be described.

[0052] First, the user rotates the rear cover 26 (see FIG. 1) of the power supply device 10 to expose the cable housing portion 52 and the connector holding portion 54 (see FIGS. 2 and 3) to the outside.

[0053] Next, the user removes the connector 20 from the connector holding portion 54. In this case, the user presses the release button 90 to release the locked state between the engagement claw 104 and the stepped portion 306. The user can remove the connector 20 from the main portion 62 by pulling the connector 20 while pressing the release button 90.

[0054] Next, the user removes the cable 18 from the cable housing portion 52. The user hooks a portion of the removed cable 18 onto the first support portion 56, and then returns the rear cover 26 to its original position. As a result, the portion of the cable 18 is supported by the first support portion 56 and the second support portion 82, and is surrounded by the surrounding portion 86.

[0055] Next, the user inserts the fitting portion 78 of the connector 20 into the mounting recess 122 of the connector 120 of the vehicle 14 (see FIG. 2). At this time, the engagement claw 104 of the latch portion 92 of the connector 20 is pressed by the inner wall of the mounting recess 122 and temporarily retracts into the fitting portion 78. When the fitting portion 78 moves toward the tip end and the engagement claw 104 faces the engagement recess 124, the engagement claw 104 is released from the pressing state by the inner wall of the mounting recess 122 and protrudes radially outward from the fitting portion 78 to engage with the engagement recess 124. As a result, the two connectors 20, 120 are connected.

[0056] Next, when the user presses a switch (not shown), the power supply device 10 starts up with DC power (low-voltage DC power) supplied from the battery of the vehicle 14. Next, when the user presses another switch (not shown), the power supply device 10 converts the other DC power (high-voltage DC power) supplied from the battery into AC power. The converted AC power is output (supplied) to the outside from an output terminal (not shown).

[0057] Thereafter, when the user operates another switch again, the power supply device 10 stops outputting AC power to the outside. Next, when the user operates a switch, the power supply device 10 stops driving.

[0058] Next, the user presses the release button 90 while holding the grip 74 of the connector 20. This causes the latch portion 92 to rotate, and the engagement between the engagement claw 104 and the engagement recess 124 is released. The user removes the connector 20 from the connector 120 of the vehicle 14 by pulling out the connector 20 while pressing the release button 90.

[0059] Then, the user opens the rear cover 26, removes the cable 18 from the first support portion 56, and stores the cable 18 in the cable storage portion 52. The user also inserts the connector 20 into the main portion 62. At this time, the user inserts the fitting portion 78 of the connector 20 into the fitting recess 70 of the main portion 62. The engagement claw 104 of the latch portion 92 of the connector 20 is pressed by the inner wall of the fitting recess 70 and temporarily retracts into the inside of the fitting portion 78. When the fitting portion 78 moves toward the tip end and the engagement claw 104 faces the locking groove 304, the engagement claw 104 is released from the state of being pressed by the inner wall of the fitting recess 70, protrudes radially outward from the fitting portion 78, and locks with the step portion 306. As a result, the connector 20 is held by the main portion 62. The user then returns the rear cover 26 to its original position.

[0060] 10 to 12 show a power supplying device 400 of a comparative example. In the power supplying device 400, the same components as those in the power supplying device 10 will be described with the same reference numerals.

[0061] In the power supply device 400, the connector 20 is larger than that in the power supply device 10. Therefore, when the connector 20 is held by the main portion 62, the connector 20 overlaps with the base end of the cable 18 and the grommet 50 in rear view in Fig. 10. The base end of the cable 18 and the grommet 50 cannot be seen.

[0062] Furthermore, in the power supply device 400, the fixing part 64 does not have fastener holes 270, 272. The insertion holes 266, 268 are formed penetrating the fixing part 64. Therefore, the lengths of the two insertion holes 266, 268 are different from each other. The lengths of the two collars 278, 280 disposed in the two insertion holes 266, 268 are also different from each other. The lengths of the two bolts 68, 69 are also different from each other. When the two bolts 68, 69 are screwed into the two nuts 274, 276, the heads 284, 288 abut against the rear surface of the fixing part main body 260.

[0063] In this way, in the power supply device 400 of the comparative example, the two collars 278, 280 have different lengths, and the two bolts 68, 69 have different lengths. Therefore, it is necessary to prepare collars 278, 280 and bolts 68, 69 of different shapes and sizes, which increases the cost of the power supply device 400. In addition, the lengths of the two insertion holes 266, 268 are different, which increases the manufacturing cost of the power supply device 400.

[0064] 2 and 3, in the power supply device 10 according to the present embodiment, the connector 20 does not overlap with the base end of the cable 18 and the grommet 50. The base end of the cable 18 and the grommet 50 can be seen.

[0065] In addition, in the power supply device 10 according to this embodiment, the two insertion holes 266, 268 have the same shape and size, and the two fastener holes 270, 272 have the same shape and size. This allows the manufacturing cost of the power supply device 10 to be reduced.

[0066] Furthermore, in the power supply device 10 according to this embodiment, the two collars 278, 280 have the same shape and size, and the two bolts 68, 69 have the same shape and size. This allows the cost of the power supply device 10 to be reduced.

[0067] This embodiment has the following advantages.

[0068] 2 and 3, the connector 20 that is not attached to the connector 120 can be suitably held by the connector holding portion 54. In addition, the direction in which the connector 20 is inserted into or removed from the main portion 62 (first direction) and the fixing direction of the fixing portion 64 by the bolts 68, 69 (second direction) intersect with each other, so that the fixing portion 64 does not interfere with the insertion or removal of the connector 20 into or removed from the main portion 62.

[0069] As shown in FIG. 4 , the connector holding portion 54 including the bolts 68, 69 can be easily fixed to the housing 22 by inserting the bolts 68, 69 into the fastener holes 270, 272, abutting the heads 284, 288 with a tool 290, and fixing the bolts 68, 69 to the frame 256 of the housing 22.

[0070] Since outer periphery 298 of main portion 62 and outer periphery 296 of fixing portion main body 260 which forms fastener holes 270, 272 are integrally formed, the strength of connector holding portion 54 can be ensured even when holes are formed in main portion 62 and fixing portion 64. Also, compared to a case where the insertion / removal direction (first direction) of connector 20 with respect to main portion 62 and the fixing direction (second direction) of fixing portion 64 by bolts 68, 69 coincide with each other, the amount of protrusion of connector 20 in the second direction in a state where connector 20 is held by connector holding portion 54 can be reduced.

[0071] The bolts 68, 69 inserted into the fastener holes 270, 272 can be easily fastened to the frame 256 by inserting a tool 290 into the fastener holes 270, 272 and abutting the tool 290 against the heads 284, 288 of the bolts 68, 69.

[0072] When the bolts 68, 69 are inserted into the fastener holes 270, 272 and the threaded portions 282, 286 are inserted into the insertion holes 266, 268, the bolts 68, 69 are fixed to the frame 256 using a tool 290, so that the heads 284, 288 come into contact with the bottoms 271, 273 of the fastener holes 270, 272. This allows the fixing portion 64 to be effectively fixed to the frame 256.

[0073] Since the length of fastener holes 270, 272 in the front-rear direction is greater than the length of insertion holes 266, 268 in the front-rear direction, the thickness of fixing portion 64 in the front-rear direction can be increased to ensure the strength of connector holding portion 54.

[0074] Even if the length of the insertion holes 266, 268 in the front-rear direction is shorter than the length of the fastener holes 270, 272 in the front-rear direction, the strength of the connector holding portion 54 can be ensured by providing the collars 278, 280.

[0075] Since the two fastener holes 270, 272 are disposed spaced apart from each other in the vertical direction, the two bolts 68, 69 are less likely to interfere with insertion and removal of the connector 20 into the main portion 62. In addition, the two bolts 68, 69 can more easily support loads in the vertical direction.

[0076] Since the two bolts 68, 69 have the same shape, the cost of fixing the connector holding portion 54 can be reduced.

[0077] Since the two insertion holes 266, 268 have the same shape, both the cost of manufacturing the connector holding portion 54 and the cost of fixing the connector holding portion 54 can be reduced.

[0078] The two fastener holes 270, 272 have the same depth dimension, which makes it possible to make the thickness of the fixing portion 64 uniform. This makes it possible to reduce the cost of manufacturing the fixing portion 64 while ensuring the strength of the fixing portion 64.

[0079] Since the front-rear direction is perpendicular to the rear wall 46 , the bolts 68 , 69 can be effectively fixed to the rear wall 46 .

[0080] Since the bolts 68 , 69 are disposed closer to the outer edge of the rear wall 46 than the main portion 62 , the bolts 68 , 69 can be effectively prevented from interfering with the insertion and removal of the connector 20 into the main portion 62 .

[0081] As shown in Figures 2 and 3, the connector 20 is held in the main portion 62 so that the base end of the connector 20 faces the corner 308 of the other side 307 of the rear wall 46, making it possible to hold a variety of connectors 20 inside the rear wall 46.

[0082] When viewed from behind the rear wall 46, the connector 20 held by the main portion 62 does not overlap with the base end of the cable 18, so that the state of the base end of the cable 18 can be easily visually confirmed from the outside.

[0083] The cable 18 extends to the outside of the power supply device 10 through a communication hole 48 that connects the inside and outside of the power supply device 10, so that when the connector 20 is attached to the connector 120, it becomes possible to transmit and receive electric power between the power supply device 10 and the vehicle 14.

[0084] Covering the communication hole 48 with the grommet 50 can prevent rainwater and the like from entering the inside of the power supply device 10. In addition, since the grommet 50 and the connector 20 held by the main portion 62 do not overlap when viewed from behind the rear wall 46, the state of the grommet 50 can be easily visually confirmed from the outside.

[0085] As shown in FIG. 6, by surrounding a portion of the cable 18 with the first support portion 56, the second support portion 82, and the surrounding portion 86, the cable 18 can be supported even if the cable 18 is thin.

[0086] As shown in Figures 2 and 3, the tip surface 80 of the connector body 76 and the opening end surface 72 of the main portion 62 are both flat, so that the mating portion 78 of the connector 20 can be effectively mated with the mating recess 70 of the main portion 62.

[0087] The effects of this embodiment will be further described.

[0088] As shown in FIG. 3, in this embodiment, the holding angle of the connector 20 with respect to the horizontal plane of the main part 62 and the distance between the fastening point of the bolt 69 in the fixing part 64 and the central axis of the main part 62 are optimized. Specifically, the distance between the central axis of the main part 62 and the fastening point of the bolt 69 is increased. This allows the inner diameter of the fastener holes 270, 272 to be increased, and the tool path for fastening the bolts 68, 69 to be secured. In addition, even if the collars 278, 280 are shortened, the wall thickness of the fixing part 64 required to secure the holding strength of the connector 20 in the main part 62 can be secured. Furthermore, it is possible to align the collars 278, 280 to a general-purpose length, and it is possible to reuse parts of other models of power supply devices. This allows the unit price of parts used in the power supply device 10 to be reduced.

[0089] As shown in FIG. 4, the length of the bolts 68, 69 and the collars 278, 280 can be shortened, and therefore the weight of each of the bolts 68, 69 and the collars 278, 280 can be reduced.

[0090] As described above, in this embodiment, the collars 278, 280 are unified into one type, and therefore, when the collars 278, 280 are set in a mold in the molding process of the connector holding portion 54, it is not necessary to check whether the collars 278, 280 of the correct length are attached to the set position. Also, since the collars 278, 280 are shorter, it becomes easier to mold the connector holding portion 54 by insert molding. Furthermore, since the collars 278, 280 are shorter, it becomes easier to outsert the collars 278, 280 after molding the connector holding portion 54.

[0091] As shown in FIG. 5, in this embodiment, the outer portion of the outer periphery 296 is tapered toward the rear, so that a clearance with the rear cover 26 can be ensured.

[0092] Furthermore, in this embodiment, since the first support portion 56 does not have a protrusion, the first support portion 56 can hold even a cable 18 with a large diameter.

[0093] Next, a modification of this embodiment will be described.

[0094] In this embodiment, the case where the power device is the power supply device 10 has been described. In this embodiment, the power device may be any device that can supply power to the outside. Therefore, instead of the power supply device 10, this embodiment can be applied to various power devices such as a portable inverter, a portable power supply, a battery power source, an electric vehicle, and a charger.

[0095] In the present embodiment, the main portion 62 and the fixing portion 64 are integrally formed. In the present embodiment, the main portion 62 and the fixing portion 64 may be formed separately from each other and connected to each other using a connecting means (not shown).

[0096] In this embodiment, the fixing portion 64 may be fixed to the housing 22 by three or more bolts 68, 69. In this case, three or more fastener holes 270, 272, etc. are formed in the fixing portion 64.

[0097] In this embodiment, the two fastener holes 270, 272 have slightly different shapes. In this embodiment, the two fastener holes 270, 272 only need to have the same depth dimension for inserting the tool 290. Therefore, the two fastener holes 270, 272 may have the same shape and size.

[0098] 2 and 3, the grommet 50 does not overlap with the connector 20 held by the main portion 62. In the present embodiment, it is sufficient that at least a portion (half or more) of the grommet 50 does not overlap with the connector 20 held by the main portion 62.

[0099] In this embodiment, a case has been described in which the communication hole 48 and the base end of the cable 18 are covered with the grommet 50. In this embodiment, the communication hole 48 and the base end of the cable 18 may be covered with a cover or a boot to prevent the intrusion of foreign matter such as rainwater.

[0100] In the present embodiment, a case has been described in which the cable 18 is extended outside the power supply device 10 and the connector 20 is connected to the tip of the cable 18. In the present embodiment, only the connector 20 may be exposed outside the power supply device 10, and the cable 18 may be connected to the connector 20.

[0101] In this embodiment, the connector holding portion 54 is fixed to the power supply device 10 by bolts 68 and 69. In this embodiment, the connector holding portion 54 may be fixed to the vehicle 14 by the bolts 68 and 69. Alternatively, in this embodiment, the connector holding portion 54 may be held by some kind of holding main body by the bolts 68 and 69. In this case, the holding main body may be a holding main body provided for fixing the connector holding portion 54. An example of such a holding main body is a support pole erected on the ground or the like. The connector 20 can be suitably held by the connector holding portion 54 fixed to such a holding main body or the like.

[0102] In addition to the above disclosure, the following notes are also disclosed.

[0103] (Appendix 1) A holding structure (10) that holds a power terminal (20) that is provided at an end of a power line (18) extending from an electric power device (10) and that is detachably provided to another power terminal (120) of another electric power device (14), the holding structure including a holding portion (54) that holds the power terminal so that the power terminal can be removably inserted when the power terminal is not attached to the other power terminal, the holding portion being fixed to a holding main body, which is either the electric power device, the other electric power device, or a holding main body, by a fixing device (68, 69), the holding portion having a main portion (62) that holds the power terminal and a fixing portion (64) that is formed integrally with the main portion and fixed to the holding main body by the fixing device, the main portion and the fixing portion being arranged such that a first direction that is a direction in which the power terminal is inserted or removed from the main portion and a second direction that is a direction in which the fixing portion is fixed to the holding main body by the fixing device intersect each other.

[0104] According to the present invention, the power terminal that is not attached to another power terminal can be suitably held by the holding part. Also, since the first direction and the second direction intersect, the fixing part does not interfere with the insertion and removal of the power terminal into and from the main part.

[0105] (Appendix 2) In the retaining structure described in Appendix 1, the fastener has a small diameter portion (282, 286) to be inserted into the retaining main body or the like, and a large diameter portion (284, 288) formed integrally with the small diameter portion and against which a tool (290) for fastening the fastener to the retaining main body or the like abuts, and the fastener has an inner diameter larger than the outer diameter of the large diameter portion, and may have a fastener hole (270, 272) formed so that the entire fastener can be inserted.

[0106] This makes it possible to easily fix the holding part including the fixing portion to the holding main body, etc. by inserting the fixing device into the fixing device hole, abutting the tool against the large diameter portion, and fixing the fixing device to the holding main body, etc.

[0107] (Appendix 3) In the holding structure described in Appendix 2, the outer periphery (298) of the main part and another outer periphery (296) of the fixing part that constitutes the fastener hole may be integrally formed.

[0108] Since the outer periphery of the main part and the other outer periphery constituting the fastener hole are integrally formed, the strength of the holding part can be ensured even when holes are formed in the main part and the fixing part. Also, compared to the case where the first direction and the second direction are the same, the amount of protrusion of the power terminal in the second direction when the power terminal is held by the holding part can be reduced.

[0109] (Appendix 4) In the retention structure described in Appendix 2 or 3, the inner diameter of the fastener hole may be larger than an outer diameter of the tool.

[0110] This makes it possible to easily fix the fastener inserted into the fastener hole to the holding main body, etc., by inserting a tool into the fastener hole and abutting the tool against the large diameter portion of the fastener.

[0111] (Appendix 5) In the retaining structure described in any one of Appendices 2 to 4, the fixing portion has an insertion hole (266, 268) that penetrates a bottom (271, 273) of the fastener hole and into which the small diameter portion is inserted, and the bottom of the fastener hole may be an abutment portion against which the large diameter portion abuts when the fastener is fixed to the retaining main body or the like.

[0112] With this configuration, when the fastener is inserted into the fastener hole and the fastener is fixed to the holding main body or the like using a tool with the small diameter portion inserted into the insertion hole, the large diameter portion abuts against the abutment portion, and as a result, the fastener can be effectively fixed to the holding main body or the like.

[0113] (Appendix 6) In the holding structure according to claim 5, a length of the fastener hole in the second direction may be greater than a length of the insertion hole in the second direction.

[0114] This makes it possible to increase the length of the fastener hole in the second direction compared to the length of the insertion hole in the second direction, thereby making it possible to increase the thickness of the fixing portion in the second direction and ensure the strength of the holding portion.

[0115] (Appendix 7) In the retaining structure described in Appendix 6, the retaining portion further has a reinforcing portion (278, 280) interposed between the insertion hole and the fastener, and the reinforcing portion may have at least one of strength and rigidity greater than that of the retaining portion.

[0116] With this, even if the length of the insertion hole in the second direction is shorter than the length of the fastener hole in the second direction, the strength of the holding portion can be ensured by providing the reinforcing portion.

[0117] (Appendix 8) In the holding structure according to any one of Supplementary Notes 2 to 7, the fixing portion may have two of the fastener holes, and two of the fasteners may be inserted into each of the two fastener holes.

[0118] This allows the holding section including the fixing portion to be fixed more firmly to the holding main body or the like.

[0119] (Appendix 9) In the retaining structure described in Appendix 8, the two fastener holes may be disposed spaced apart from each other in the vertical direction.

[0120] This makes it possible for the two fixing devices to be less likely to interfere with the insertion and removal of the power terminals from the main unit, and also makes it easier for the two fixing devices to support a vertical load.

[0121] (Appendix 10) In the holding structure according to appended claim 8 or 9, the two fasteners may have the same shape.

[0122] This makes it possible to reduce the cost of fixing the holding portion.

[0123] (Appendix 11) In the holding structure according to any one of appendices 8 to 10, the insertion holes of the two fastener holes may have the same shape.

[0124] This makes it possible to reduce both the cost of manufacturing the holding portion and the cost of fixing the holding portion.

[0125] (Appendix 12) In the holding structure according to any one of appendixes 8 to 11, the two fastener holes may have the same depth dimension.

[0126] This allows the thickness of the fixing portion to be uniform, which in turn allows the strength of the fixing portion to be ensured while reducing the cost of manufacturing the fixing portion.

[0127] (Appendix 13) In the holding structure described in any one of Supplementary Notes 1 to 12, the holding structure may further include a fixing surface (46) for fixing the fixing portion, and the second direction may be a direction perpendicular to the fixing surface.

[0128] This allows the fixing portion to be effectively fixed to the fixing surface of the holding structure.

[0129] (Appendix 14) In the holding structure described in Supplementary Note 13, the fixing portion may be disposed closer to an outer edge of the fixing surface than the main portion.

[0130] This effectively prevents the fixing portion from interfering with the insertion and removal of the power terminal from the main portion.

[0131] (Appendix 15) In the holding structure described in Appendix 14, the fixing surface may be formed in a rectangular shape, the fixing portion may be arranged on one side (66) of the rectangle, and the main portion may be arranged such that the end portion of the power terminal held by the main portion on the power line side faces a corner portion (308) of another side (307) opposite the one side.

[0132] This allows the power terminal to be held by the main part so that the end of the power terminal faces the corner of the other side, making it possible to hold a variety of power terminals inside the fixing surface.

[0133] (Appendix 16) In the holding structure described in any one of Appendices 13 to 15, the holding portion may be arranged so that, when viewed from the front of the fixing surface, the power terminal held in the main portion does not overlap with the end of the power line on the power device side.

[0134] This makes it possible to easily visually check the state of the end (proximal end) of the power line on the power device side from outside.

[0135] (Appendix 17) In the holding structure described in appendix 16, the power line may extend to the outside of the power device through a communication hole (48) that communicates between the inside and the outside of the power device.

[0136] This makes it possible to transfer power between the power device and the other power device when the power terminal is attached to another power terminal.

[0137] (Appendix 18) In the holding structure described in Appendix 17, the power device has a covering lid portion (50) that covers the communication hole, and the holding portion may be arranged so that the power terminal held in the main portion does not overlap with the covering lid portion when viewed from the front of the fixing surface.

[0138] In this way, by covering the communication hole with the cover part, it is possible to prevent rainwater, etc. from entering the inside of the electric power device. In addition, since the cover part and the power terminal held by the main part do not overlap when viewed from the front of the fixing surface, the state of the cover part can be easily visually confirmed from the outside.

[0139] (Appendix 19) In the holding structure described in any one of Appendices 13 to 18, the fixing surface may be a part of an outer surface of the power device, the fixing surface may be provided with a power line housing (52) that houses the power line and a cover member (26) that covers at least a part of the fixing surface, the cover member may be rotatable with respect to the fixing surface, the power line may be pulled out of the power line housing in a state in which the cover member is rotated with respect to the fixing surface, the fixing portion may be provided with a first support portion (56) that supports a part of the power line pulled out from the power line housing, the fixing surface may be provided with a second support portion (82) that supports another part of the power line when the part of the power line is supported by the first support portion, and the cover member may be provided with a surrounding portion (86) that surrounds a part of the power line when the cover member covers at least a part of the fixing surface in a state in which the part and the other part of the power line are supported by the first support portion and the second support portion.

[0140] With this, by surrounding a portion of the power line with the first support portion, the second support portion, and the surrounding portion, it is possible to support the power line even if the power line is thin.

[0141] (Appendix 20) In the holding structure described in any one of Appendices 1 to 19, the power terminal has a gripping portion (74) connected to a tip of the power line and grippable by a user, a terminal body (76) connected to the gripping portion, and a fitting portion (78) protruding from a tip face (80) of the terminal body and fitable into a fitting opening (122) of the other power terminal, and a fitting recess (70) that fits into the fitting portion is formed on the inside of the main portion, and both the tip face of the terminal body and an opening end face (72) of the main portion on which the fitting recess is formed may be flat.

[0142] With this, since the tip surface of the terminal body and the open end surface of the main portion are both flat, the fitting portion of the power terminal can be effectively fitted into the fitting recess of the main portion.

[0143] The present invention is not limited to the above disclosure, and various configurations can be adopted without departing from the gist of the present invention. [Explanation of symbols]
