The outlet unit 10 includes a housing 11, an outlet block 12, a door 13, a wiring cover 14, a ceiling cover 15 and the like as shown in FIGS. The housing 11 is formed in a box shape having an opening window 11A on the front surface by a metal plate. The door 13 is formed in a flat rectangular box shape, and is hinged so as to be rotatable in a horizontal direction (front-rear direction) between a closed position that closes the opening window 11A and an open position that opens the opening window 11A. The left end is pivotally supported by the front left end of the housing 11 by the portion 13A. Moreover, the locking device 16 is attached to the door 13, and the door 13 is locked by the locking device 16 when it is in the closed position. In addition, a notch (extraction port) 13 B from which the charging cable 200 is drawn is formed at the center in the left-right direction at the lower end of the door 13.
The outlet block 12 includes an outlet 120 provided with an insertion port (not shown) on the front surface, an outlet plate 12A that holds the outlet 120 and covers the front surface of the outlet 120, and a plug that opens at the center of the outlet plate 12A. And an outlet cover 12C for closing the opening 12B so as to be freely opened and closed. In the outlet plate 12A, the central portion where the plug insertion port 12B is opened projects forward, and screw insertion holes 120 are formed in the left and right ends of the central portion. The outlet cover 12C is formed in a substantially semi-disc shape, and is pivotally supported by the central portion of the outlet plate 12A at the straight portion. That is, the outlet cover 12C rotates between a closed position that covers the plug insertion opening 12B of the outlet plate 12A and an open position that opens the plug insertion opening 12B, and is further opened by the spring force of a torsion coil spring (not shown). It is elastically urged in the direction toward the closed position. However, the outlet cover 12C is provided with a lock claw 12F, and in the closed position, the rotation of the outlet cover 12C is restricted by the lock claw 12F engaging with the outlet plate 12A. Note that an engagement portion 12E that engages with an engaged portion (not shown) of the plug 201 provided at the tip of the charging cable 200 is provided on the inner surface of the outlet plate 12A. The plug 201 inserted and connected to the insertion port is prevented from being detached by the engagement between the engaging portion 12E and the engaged portion (see FIG. 5).
The outlet block 12 is screwed to a mounting plate 11B disposed on the upper rear side inside the housing 11 by screws (not shown) inserted through screw insertion holes 12D at both left and right ends. Here, the mounting plate 11B is disposed so as to be gradually lowered downward toward the rear. For this reason, the outlet 120 of the outlet 120 is also tilted downward with respect to a horizontal plane (a plane including front, rear, left and right). Further, the bottom plate (inner bottom plate) 11C inside the housing 11 is inclined so as to gradually rise upward toward the rear (see FIG. 4). In other words, rainwater that has entered the casing 11 through the opening window 11A is drained out of the casing 11 from the opening window 11A through the inner bottom plate 11C inclined forward.
Further, the outlet unit 10 is provided with an interlock device. When the door 13 is not in the closed position, the power supply to the outlet 120 is turned off by this interlock device, and only when the door 13 is in the closed position. Energization to the outlet 120 is turned on. Such an interlock device is well known in the art and includes an actuator 20 that is pushed by a drive piece 13C that protrudes rearward from the rear surface of the door 13. When the door 13 is in the closed position, the actuator 20 When the drive piece 13C is pushed to close the power supply path to the outlet 120, and the door 13 is not in the closed position, the actuator 20 is not pushed by the drive piece 13C to open the power supply path to the outlet 120.
By the way, a space (wiring space) in which a power supply line (not shown) to the outlet 120 is wired is provided on the back side of the housing 11. This wiring space is formed by a rectangular box-shaped wiring cover 14 that is screwed to the back surface of the housing 11. In addition, screw holes 11D and 11D are formed in the left and right ends of the rear surface of the housing 11 on the upper and lower sides of the screwing portion of the wiring cover 14, respectively.
The ceiling cover 15 is formed in a box shape having an open bottom surface, and is attached to the housing 11 so as to cover the top surface (upper surface) of the housing 11 and the wiring cover 14. A portion of the ceiling cover 15 that covers the wiring cover 14 is provided with an inlet (not shown) for drawing the power supply line into the wiring space (see FIG. 3). However, a wall 15 A that rises upward protrudes around the entrance opening in the ceiling cover 15. Further, a plurality of protrusions 15B along the left-right direction are arranged in the front-rear direction on the upper surface of the ceiling cover 15, and the protrusions 15B prevent rainwater that has entered from the front from moving backward (FIG. 3). reference).
A terminal block 17 is attached to the upper part of the back surface of the housing 11 covered with the wiring cover 14 (see FIG. 1). The terminal block 17 is a well-known screw type, and a three-pole terminal screw (not shown) including a grounding electrode is arranged in parallel on the front surface (rear surface in FIG. 1), and on the rear surface (front surface in FIG. 1). Three projecting terminal pieces 17A are introduced into the housing 11 through a rectangular window hole 11E formed on the back surface of the housing 11. Although not shown in the figure, the feeder line that is inserted from the entry port of the ceiling cover 15 is connected to the screw terminal of the terminal block 17, and the three terminal pieces 17A introduced through the window holes 11E are respectively connected by lead wires. It is connected to the terminal part of the outlet 120.
Here, since the outlet device (outlet unit 10) and the charging stand of this embodiment are usually installed outdoors, there is a high possibility that rainwater will enter the housing 11 when the door 13 is open. Therefore, in the present embodiment, a ridge portion 18 that protrudes forward from the upper and side portions of the peripheral edge of the opening window 11A on the front surface of the housing 11 is provided. The protrusion 18 includes a horizontal piece 18A that protrudes forward from the entire upper side of the rectangular opening window 11A, and a pair of

vertical pieces

18B and 18B that protrude forward from a part of the left and right sides of the opening window 11A. The horizontal piece 18A and the

vertical pieces

18B and 18B have a rising piece 18C that rises outward (in a direction away from the opening window 11A) from the front end. However, the range in which the protrusion 18 protrudes at the peripheral side of the opening window 11A is the upper part of the peripheral edge of the opening window 11A, for example, in this embodiment, the outlet block 12 as viewed from the front as shown in FIG. It is the range above the upper end of the plug insertion opening 12B. However, the range in which the protruding portion 18 protrudes (the upper portion at the periphery of the opening window 11A) is not necessarily the range shown in FIG. 13, and is, for example, a range about half from the top in the periphery side portion of the opening window 11A. It may be. In short, it may be in a range where the hand holding the plug 201 is difficult to hit when the plug 201 is inserted into and removed from the outlet of the outlet. In the present embodiment, the shape of the opening window 11A is rectangular (square), but other shapes such as a circle or an ellipse may be used, and in this case, the upper portion (for example, the periphery of the opening window 11A (for example, It is only necessary that the protrusion 18 protrudes only in the upper semicircle range). Moreover, the protrusion part 18 is formed in the dimension settled inside the door 13 when the door 13 exists in a closed position (refer FIG. 2).
Thus, the horizontal piece 18A and the

vertical pieces

18B, 18B of the ridge 18 become eaves, and the intrusion of rainwater from the opening window 11A into the housing 11 is suppressed. Here, when the protruding portion 18 protrudes from the front surface of the housing 11, there is a possibility that the operation of putting the hand into the housing 11 and inserting and removing the Bragg 201 into the insertion port of the outlet 120 may be difficult. However, in the present embodiment, as described above, the range in which the protruding portion 18 protrudes at the peripheral edge portion of the opening window 11A is limited to the upper portion at the periphery of the opening window 11A. Intrusion of rainwater into the housing 11 can be suppressed while suppressing the above. In the present embodiment, since the rising piece 18C is provided at the front end of the horizontal piece 18A and the

vertical pieces

18B and 18B, rain water applied to the horizontal piece 18A and the vertical piece 18B is blocked by the rising piece 18C. The water is drained from the left and right ends of the opening window 11A along the vertical piece 18B without dripping forward. Further, as already described, since the inner bottom plate 11C of the housing 11 is inclined so as to gradually fall downward toward the front, rainwater that has entered the housing 11 through the opening window 11A travels through the inner bottom plate 11C. Water is drained from the opening window 11 A to the outside of the housing 11. In addition, since the outlet 120 (outlet block 12) is disposed in a direction in which the plug 201 is inserted into the insertion port in a direction substantially parallel to the inner bottom plate 11C of the casing 11, the vertical direction of the casing 11 ( The inclination angle of the inner bottom plate 11C can be increased without increasing the dimension in the vertical direction), and drainage performance can be improved.
The outlet unit 10 configured as described above is attached to the inner side surfaces of the pair of stand

main bodies

1 and 1 using the

fixtures

3 and 3 and disposed in the storage space. That is, after the fixture 3 is attached to the inner surface of the stand body 1, the outlet unit 10 is stored in the storage space from the front. Then, the mounting screw 34 inserted through the screw insertion hole 31A of the unit side fixing portion 31 of the fixture 3 is fastened to the screw hole 11D on the back surface of the housing 11, whereby the unit side fixing portion 31 is fixed to the housing 11. The outlet unit 10 is attached to the stand

main bodies

1 and 1. Further, the back cover 5 made of a metal plate is screwed to the back cover fixing portion 32 of the fixture 3, whereby the back side of the storage space in which the outlet unit 10 is stored is closed by the back cover 5. When a plurality of outlet units 10 are stored in the storage space, a plurality (two in the illustrated example) of outlet units 10 are arranged in the vertical direction as shown in FIGS. 8 and 9. .
By the way, the outlet device according to the present invention does not necessarily need to be used in combination with the charging stand of the present embodiment, and may be installed embedded in an embedded hole provided in a building wall, for example. Further, the charging facility according to the present invention is not limited to the charging stand of the present embodiment. For example, the charging facility is configured such that the outlet device (outlet unit 10) is housed inside the gate pole, or is installed on the wall of the building. The outlet device (the outlet unit 10) may be stored in a box (box) side by side in the vertical and horizontal directions.
