As shown in FIGS. 1 and 2, the charging stand according to the present embodiment is a stand main body 1 standing on the ground where an electric vehicle is parked, and a power cable (hereinafter referred to as a charging cable) for charging the electric vehicle. ) 100 plugs 110 are provided with an outlet 20 that is plugged into and removed from the insertion port 20a.

  The stand body 1 is a rectangular tube with front, top and bottom surfaces opened by assembling three metal plates (left side plate 2, right side plate 3, back plate 4) formed in a long rectangular plate shape. The opening on the top surface is closed by a flat box-shaped cover 5. On the inner side surfaces of the left side plate 2 and the right side plate 3, a mounting plate made of a rectangular plate-like metal plate and having a substantially central portion in the left-right direction (horizontal direction) bent in a step shape along the vertical direction (vertical direction) 6 is attached in parallel with the back plate 4 (see FIGS. 2 and 3). That is, the inside of the stand main body 1 is divided into front and rear by the mounting plate 6, and an outlet unit 10 to be described later is housed in a space in front of the mounting plate 6, and an earth leakage breaker 200 to be described later and a power supply cable for power supply (see FIG. (Not shown) is housed (wired) in the space behind the mounting plate 6. A plurality of screw holes 6a for attaching the outlet unit 10 and the earth leakage breaker 200 are provided in the mounting plate 6 at regular intervals along the vertical direction and the horizontal direction.

  A rectangular plate-like upper panel 7A and lower panel 7B are attached to the uppermost and lowermost parts of the front surface of the stand body 1. In the stand body 1, four storage spaces 8 for storing the outlet units 10 are juxtaposed in the vertical direction in the front space from the lower end of the upper panel 7 </ b> A to the upper end of the lower panel 7 </ b> B.

  As shown in FIG. 8, the outlet unit 10 has a box-shaped casing 11 having an opening window 11a on the front surface, an outlet block 12 held in the casing 11, and a closed position for closing the opening window 11a (see FIG. 4). ) And an open position that opens the opening window 11a, and a door 13 that is rotatable in the horizontal direction, and a unit cover 16 made of a synthetic resin material that covers the top of the housing 11. As shown in FIG. 9, the housing 11 has a substantially central portion in the left-right direction of the back plate 11b bent in a step shape along the vertical direction (vertical direction), and the depth from the opening window 11a to the back plate 11b is large. The outlet block 12 is disposed at the corner on the large side (left side).

  The outlet block 12 has an outlet 20 provided with an insertion port 20a on the front surface of a rectangular box-shaped container 20b, and a fitting hole 21a into which the front end of the outlet 20 is fitted, and the outlet 20 is attached from the rear. A plate-shaped outlet panel 21 is provided. The outlet panel 21 is formed in a substantially hexagonal shape, and is attached to the left corner in the housing 11 so that the lower end is located rearward with respect to the upper end and the right end is located rearward with respect to the left end. Yes. The outlet 20 is housed in a space surrounded by the inner wall surface of the casing 11 and the outlet panel 21, and the outlet 20 a of the outlet 20 is exposed to the inner space of the casing 11 through the fitting hole 21 a of the outlet panel 21. . Note that the outlet 20 is well known in the art, and is used for connecting a blade receiver (not shown) for receiving a contact (plug blade) of the plug 110 inserted from the insertion port 20a and an external electric wire. A terminal (not shown) is housed in a container 20b made of an insulating material.

  Thus, since the outlet panel 21 is mounted in the housing 11 so that the lower end is located rearward with respect to the upper end and the right end is located rearward with respect to the left end, the outlet attached to the outlet panel 21 is provided. 20, the insertion / extraction direction of the plug 110 with respect to the insertion port 20 a obliquely intersects the opening window 11 a in the horizontal direction and the vertical direction, in other words, the direction of the insertion port 20 a (the normal direction of the front surface of the outlet 20) is the opening window 11 a. (See FIG. 1) so as to be inclined obliquely downward to the right with respect to the direction (normal direction of the opening surface of the opening window 11a).

  Here, as shown in FIG. 9, a terminal block 22 is attached to the back surface of the housing 11. This terminal block 22 is connected to a terminal of the outlet 20 through a through hole (not shown) through which one connection terminal penetrates the back plate 11b (actually, it is connected via an interlock device 23 described later). In addition, as will be described later, the electric wire connected to the secondary terminal of earth leakage breaker 200 is connected to the other connection terminal. That is, since the outlet 20 is housed in a space surrounded by the inner wall surface of the casing 11 and the outlet panel 21, the terminal block 22 is attached to the outside of the casing 11, and the terminals of the outlet 20 are connected to the outside via the terminal block 22. The connection work is facilitated by connecting the electric wires.

  The door 13 is formed in a flat rectangular box shape, and the left end is pivotally supported on the front left end of the housing 11 by a pair of upper and lower hinges 14 as shown in FIG. Moreover, the locking device 15 is attached to the back side of the door 13, and the key hole 15a of the locking device 15 is exposed on the front surface of the door 13 (see FIG. 1). Note that the lower end portion of the door 13 is notched in the horizontal direction, and a gap for pulling out the charging cable 100 from between the lower end of the door 13 and the lower end on the front side of the housing 11 when the door 13 is in the closed position. (Drawer outlet) is vacant (see FIG. 1).

  Further, the outlet unit 10 is provided with an interlock device 23. When the door 13 is not in the closed position, the power supply to the outlet 20 is turned off and the door 13 is in the closed position. Only the power supply to the outlet 20 is turned on. Such an interlock device 23 is well known in the art and has an actuator 23a that is pushed and driven by a U-shaped drive piece 13a provided on the back surface of the door 13 that rotates in the horizontal direction. When the actuator 23a is in the closed position, the actuator 23a is pushed by the drive piece 13a to close the power supply path to the outlet 20, and when the door 13 is not in the closed position, the actuator 23a is not pushed by the drive piece 13a. A power supply path to the outlet 20 is opened.

  The outlet unit 10 configured as described above is housed in the housing space 8 in the stand body 1 from the front side, and is fixed to the stand body 1 by screwing the housing 11 to the mounting plate 6. Is done. As described above, the four storage cavities 8 having the same dimensions are arranged in the vertical direction in the stand main body 1, and the outlet unit 10 can be stored in any of these four storage cavities 8. Here, a rectangular window hole 6 b is provided in the mounting plate 6 for each storage space 8, and the outlet unit 10 is mounted on the back surface of the housing 11 in a state where the outlet unit 10 is stored in the storage space 8. The terminal block 22 is inserted through the window hole 6b and exposed to the rear space (wiring space 9) of the mounting plate 6 (see FIGS. 10 to 12). However, in this embodiment, the case where the outlet unit 10 is stored in all the four storage spaces 8 is illustrated, but it is not always necessary to store the outlet unit 10 in all the four storage spaces 8, and at least 1 One outlet unit 10 may be stored in any one storage space 8.

  As shown in FIGS. 2 and 12, the earth leakage breaker 200 is attached to the rear surface of the side (left side in FIG. 12) that protrudes forward of the mounting plate 6 and is disposed in the wiring space 9. In this wiring space 9, a power cable (not shown) for supplying AC power from a commercial AC power source is inserted from the cable inlet 1 a on the bottom surface of the stand body 1 and wired up (see FIG. 7). And while the electric power cable wired by the wiring space 9 is connected to the primary side of the earth leakage breaker 200, the secondary side of the earth leakage breaker 200 is connected to one connection terminal of the terminal block 22 by the electric wire which is not illustrated, The other connection terminal of the terminal block 22 is connected to the terminal of the outlet 20 through the interlock device 23. The wiring work described above can be easily performed by simply removing the back plate 4 of the stand body 1.

  Next, the procedure for using the charging stand of this embodiment will be described. First, the door 13 is opened, and the plug 110 is plugged into the outlet 20 by inserting the contact of the plug 110 of the charging cable 100 into the insertion port 20a. At this time, since the direction of the insertion port 20a is arranged so as to be inclined obliquely downward to the right with respect to the direction of the opening window 11a, a space (space) necessary for inserting and removing the plug 110 in the housing 11 is provided. Sufficiently secured and the plug 110 can be easily inserted. Furthermore, rain water that falls into the housing 11 through the opening window 11a is not easily applied to the insertion port 20a even in rainy weather. Here, even if the outlet unit 10 is arranged close to the right side in the housing 11 and the outlet 20 is arranged so that the direction of the insertion port 20a is inclined to the lower left with respect to the direction of the opening window 11a. The same effect is produced. However, a right-handed person who is generally considered to be more likely to arrange the outlet 20 so that the insertion port 20a is tilted obliquely downward to the right from the position on the left side in the housing 11 as in the present embodiment. Has an advantage that the plug 110 can be easily inserted.

  After the plug 110 is plugged into the outlet 20, the door 13 is closed and the lock device 15 is locked using a key (not shown). Here, as in the case of the power pole described in Patent Document 1, when the outlet outlet of the outlet is almost directly facing the opening of the casing in which the outlet is stored, the plug is inserted into the outlet. The pull-out position of the plugged-in power cable and the position of the outlet of the outlet are substantially the same in the horizontal direction. For this reason, when multiple outlets are installed side by side in a vertical direction, the hanging power cable and the outlet of the lower outlet overlap each other when viewed from the front.Therefore, plug another power cable into the lower outlet. There is a problem that it becomes difficult to make a complicated connection. On the other hand, in this embodiment, each outlet 20 is disposed in the stand body 1 (in the outlet unit 10) so that the direction of the insertion port 20a is inclined obliquely downward to the right with respect to the direction of the opening window 11a. Therefore, the plug 110 is plugged into the upper outlet 20 and the charging cable 100 hanging from the opening window 11a and the outlet 20a of the lower outlet 20 do not overlap with each other when viewed from the front. The work of plugging and connecting the plug 110 of another charging cable 100 to 20 is facilitated.

  Furthermore, as shown in FIG. 1, a plurality (three) of cable holders (holding bodies) 40 are attached to the outer peripheral surface (right side surface in the present embodiment) of the stand main body 1. As shown in FIGS. 3 and 4, the cable holder 40 is formed by bending a strip-shaped metal plate into a bowl shape having a substantially U-shaped cross section, and aligning the longitudinal direction in the vertical direction and the groove at the rear. The right side plate 3 of the stand main body 1 is screwed in the vicinity of the storage space 8 in the second to fourth stages from the top so as to face.

  Thus, if the charging cable 100 drawn out of the stand body 1 (front) through the opening window 11a (drawing outlet) is fitted into the groove and held by the cable holder 40, the plug is connected to the upper outlet 20. The door 13 of the lower outlet unit 10 can be opened and closed without obstructing the charging cable 100 to which 110 is connected. Further, even when the charging cable 100 is inadvertently pulled, the cable holder 40 holds the charging cable 100, so that the tension applied to the plug 110 is relieved, and the plug 110 is inserted into the outlet 20a of the outlet 20. It can be prevented from coming off. Here, since the three cable holders 40 are arranged at positions shifted in the front-rear direction of the stand body 1 along the vertical direction, the plurality of charging cables 100 held by the cable holder 40 do not interfere with each other. It is. Furthermore, in the present embodiment, the cable holder 40 that is relatively below is disposed at a position closer to the front of the stand body 1 than the cable holder 40 that is relatively above, so that it is relatively below Since the cable holder 40 located at the front is positioned closer to the front of the stand body 1 than the charging cable 100 held by the cable holder 40 located relatively above (see FIG. 5), the cable holder 40 is relatively below. When the charging cable 100 is held by the cable holder 40 in the above, there is an advantage that the charging cable 100 held by the cable holder 40 relatively above does not get in the way.

  On the other hand, when charging of the electric vehicle is completed, the locking device 15 is unlocked, the door 13 is opened, and the plug 110 is pulled out from the insertion port 20 a of the outlet 20. Here, when the door 13 is open, the energization to the outlet 20 is turned off by the interlock device 23, so that it is possible to prevent an electric shock accident when the plug 110 is inserted into and removed from the insertion port 20a of the outlet 20. .

  As described above, according to the present embodiment, the outlet 20 is installed in the stand main body 1 (the outlet unit 10 of the outlet unit 10 so that the insertion / extraction direction of the plug 110 with respect to the insertion port 20a obliquely intersects the opening window 11a in the horizontal direction and the vertical direction. Since it is disposed in the housing 11), it is possible to suppress an increase in the size of the stand body 1 while ensuring a sufficient space for inserting and removing the plug 110 into and from the insertion port 20 a of the outlet 20. In addition, in the stand main body 1, the outlet 20 is disposed so as to be offset to the opposite side (left side in the present embodiment) of the left or right of the opening window 11a to the direction in which the insertion port 20a faces. Therefore, there is an advantage that a space for inserting and removing the plug 110 into and from the insertion port 20a of the outlet 20 can be further increased while suppressing an increase in the size of the stand body 1. When a plurality of outlets 20 are arranged in the stand body 1 along the vertical direction, the insertion / extraction direction of the plug 110 with respect to the insertion port 20a obliquely intersects the opening window 11a in the horizontal direction and the vertical direction. As a result, the plug 110 is plugged into the upper outlet 20 and the charging cable 100 hanging from the opening window 11a and the outlet 20a of the lower outlet 20 do not overlap with each other when viewed from the front. There is an advantage that the work of plugging and connecting the plug 110 of another charging cable 100 to the outlet 20 is facilitated. Further, a door 13 is provided for closing the opening window 11a so that the opening window 11a can be opened and closed, and the charging cable 100 having the plug 110 connected to the outlet 20 between the lower end of the door 13 and the lower end of the opening window 11a is pulled out of the stand body 1. In this case, it is possible to prevent rainwater from entering the opening window 11a by closing the door 13 with the door 13 and to provide the door even when the plug 110 is plugged into the outlet 20 by being provided with the outlet. 13 can be closed, and there exists an advantage that waterproofness improves.

  By the way, in this embodiment, since the insertion port 20a is inclined in the diagonally downward right direction, the insertion port 20a may not be directly visible unless the opening window 11a is viewed from below. Therefore, if a reflecting mirror is provided on the inner bottom surface of the housing 11 facing the insertion port 20a, the insertion port 20a reflected in the reflection mirror can be viewed from above the opening window 11a, and the contact of the plug 110 The workability at the time of inserting into the insertion port 20a can be improved.

  Further, since the inside of the opening window 11a becomes dark at night, for example, an illumination lamp La is installed on the inner top surface of the casing 11 as shown in FIGS. 13 (a) and 13 (b). The inside of the body 11 may be illuminated. At this time, if a reflecting mirror is provided not only on the inner bottom surface of the housing 11 but also on the inner side surface and the inner rear surface, the light emitted from the illumination light La (see solid arrows in FIGS. 13A and 13B). The space inside the opening window 11a can be efficiently illuminated by reflecting on the reflecting mirror (inner bottom surface, inner side surface, and inner back surface).

(Embodiment 2)
The present embodiment is characterized by the structure of the door 13 that closes the opening window 11a. Therefore, since the configuration other than the door 13 is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and illustration and description thereof are omitted.

  In the first embodiment, the lower end portion of the door 13 is all cut out to the left and right ends. On the other hand, in this embodiment, only the corner on the free end side (right side when viewed from the front) of the lower end portion of the door 13 is partially cut out, and this cut out portion is a power cable (charging). It becomes the outlet 18 of the cable 100) (see FIG. 14 and FIG. 15).

  That is, when the charging cable 100 of the plug 110 plugged into the outlet 20 is drawn straight out from the outlet in the horizontal plane, when the charging cable 100 is pulled, particularly from the cable holder 40 to the door 13. When the portion between them is pulled, tension is applied to the plug 110 and the plug 110 may come out of the insertion port 20a of the outlet 20, or the connection portion between the charging cable 100 and the plug 110 may be deteriorated.

  On the other hand, in this embodiment, as shown in FIG. 16, a straight line (broken line a in FIG. 16) connecting the outlet 18 and the insertion port 20a is the normal direction of the insertion port 20a in the horizontal direction (one point in FIG. 16). The outlet 18 is provided close to the right end so as to intersect the broken line (b). For this reason, the charging cable 100 is curved in the casing 11 of the outlet unit 10 (see FIG. 16), and the tension of the charging cable 100 is applied to the part of the outlet 18 of the door 13, which is compared with the first embodiment. Thus, the tension applied to the plug 110 can be relaxed, and the plug 110 can be prevented from being removed from the insertion port 20a of the outlet 20, and the connection portion between the charging cable 100 and the plug 110 can be prevented from being deteriorated.

  If a bushing (not shown) having elasticity is provided at the peripheral portion of the outlet 18 in the door 13, it is possible to prevent the outer skin (sheath) of the charging cable 100 from being damaged at the peripheral portion of the outlet 18. it can.
