FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. 4, and FIG. 7 is a view showing a state in which the charging connector is hung on the connector holder in the present embodiment. In FIG. 4, the cover 22 of the stand main body 20 is omitted.

  As shown in FIGS. 3 to 5, the connector holder 50 includes a substantially rectangular plate member 51, and first and second members protruding from the plate member 51 toward one side (side away from the stand body 20). 52 and 53, and the cylindrical part 54 which protrudes from the plate member 51 toward the other (stand main body 20 side).

  The first member 52 is a substantially rod-shaped member having a substantially U shape bent concavely at two locations, and can hold the charging connector 40 from below while surrounding the lower side of the charging connector 40. (See FIG. 7). In addition, the shape of the 1st member 52 will not be specifically limited if it is a substantially U shape, For example, the shape curved continuously concavely and circularly may be sufficient. Further, in the present embodiment, the cross-sectional shape of the first member 52 is a high-aspect-ratio rectangular shape (that is, a plate shape), but is not particularly limited thereto, for example, a low-aspect-ratio rectangular shape, It may be a polygonal shape or a circular shape.

  On the other hand, the second member 53 is a substantially bar-shaped member having a substantially inverted U shape bent in a convex shape at two locations, and can contact the charging connector 40 from above while surrounding the upper side of the charging connector 40. (See FIG. 7). The shape of the second member 53 is not particularly limited as long as it is a substantially inverted U shape, and may be, for example, a shape that is continuously curved in a convex shape and an arc shape. In the present embodiment, the cross-sectional shape of the second member 53 is a rectangular shape with a high aspect ratio (that is, a plate shape), but is not particularly limited to this, for example, a rectangular shape with a low aspect ratio, It may be a polygonal shape or a circular shape.

One end of the first member 52 is a free end, and the other end is connected to the plate member 51. Similarly, the second member 53 also has a free end at one end and is connected to the plate member 51 at the other end. In this embodiment, as shown in FIG. 4, the first member 52 and the second member 52 in the longitudinal direction Ds of the plate member 51 (that is, the insertion direction Ds of the charging connector 40 into the connector holder 50 shown in FIG. 2). The members 53 are arranged so as to be shifted (offset) from each other by a distance S ₀ . For this reason, when the charging connector 40 is held by the connector holder 50, the second member 53 comes into contact with the charging connector 40 on the front end side of the charging connector 40 with respect to the first member 52.

  In the present embodiment, the “rear end side” of the charging connector 40 is the side where the charging cable 30 is introduced in the charging connector 40, whereas the “front end side” of the charging connector 40 is the charging side. The connector 40 is on the opposite side to the rear end, for example, the side attached to the power supply inlet 72 of the vehicle 70.

  As shown in FIGS. 4 to 6, the cylindrical portion 54 has a cylindrical shape and is provided on the back surface 51 a of the plate member 51. A pin insertion hole 541 is formed on the peripheral surface of the cylindrical portion 54 so as to pass through in a direction orthogonal to the axial direction of the cylindrical portion 54. As shown in FIGS. 4 and 6, the connector holder 50 is fixed to the bracket 60 by inserting the pin 55 into the pin insertion hole 541.

  The bracket 60 for attaching the connector holder 50 to the frame 21 has a main body 61 and two flanges 62 as shown in FIGS. A holder mounting hole 611 into which the cylindrical portion 54 of the connector holder 50 is inserted is formed in the approximate center of the main body portion 61.

  The flange portion 62 extends from both sides of the main body portion 61 in a substantially L shape. A pin insertion hole 621 into which the above-described pin 55 is inserted is formed in the first surface 62 a bent from the main body 61 in the flange portion 62. On the other hand, a bolt insertion hole 622 is formed in the second surface 62 b that is further bent from the first surface 62 a in the flange portion 62. Bolts 63 for fixing the bracket 60 to the frame 21 are inserted into the bolt insertion holes 622.

  As shown in FIGS. 4 to 6, a long hole 211 is formed in the frame 21 of the stand body 20 at a position where the bracket 60 is attached. The long hole 211 extends along the vertical direction.

  The connector holder 50 described above is attached to the stand body 20 of the charging stand 10 as follows.

  That is, first, the bracket 60 is fixed to the frame 21 of the stand body 20 by bolt fastening. Specifically, after aligning the bolt insertion hole 622 of the bracket 60 with respect to the long hole 211 of the frame 21, the bolt 63 is inserted into the bolt insertion hole 622 and the long hole 211, and the bolt is inserted inside the frame 21. The bracket 60 is fixed to the frame 21 by screwing the nut 64 into the threaded portion 63.

  Next, the cylindrical portion 54 of the connector holder 50 is inserted into the holder mounting hole 611 of the bracket 60 through the holder insertion hole 221 formed in the cover 22 of the stand body 20. Instead of the holder insertion hole 221, a notch for allowing the tubular portion 54 of the connector holder 50 to pass through may be formed in the cover 22.

  Next, after the pin insertion hole 541 of the connector holder 50 and the pin insertion hole 621 of the bracket 60 are aligned, the pin 55 is inserted into the pin insertion holes 541 and 621 to fix the connector holder 50 to the bracket 60. Thus, the connector holder 50 is attached to the stand main body 20.

  When the charging connector 40 is hung on the connector holder 50 described above, the charging operator connects the tip of the charging connector 40 from the first member 52 toward the second member 53 as shown in FIG. Insert into holder 50. When the charging connector 40 is inserted until the tip of the charging connector 40 exceeds the second member 53, the charging operator places the charging connector 40 on the first member 52 and releases the charging connector 40. .

  Here, since the charging cable 30 has a solid structure in which an electric wire for supplying electric power is housed, the charging cable 30 is very heavy compared to the charging connector 40.

  Therefore, when the charging connector 40 is placed on the first member 52, the charging connector 40 is counterclockwise in the drawing with the first member 52 as a fulcrum, depending on the weight of the charging cable 30, as shown in FIG. The tip of the charging connector 40 is raised. In the present embodiment, the charging connector 40 is held by the connector holder 50 by pressing the tip of the charging connector 40 that has risen in this way by the second member 53.

  Thus, in the present embodiment, the charging connector 40 is held by hooking the tip of the charging connector 40 to the second member 53 using the weight of the charging cable 30. For this reason, since the charging connector 40 can be held as long as the first and second members 52 and 53 are in contact with the charging connector 40, it can be applied to various shapes of charging connectors, and the shape of the charging connector. The dependence on the battery connector is reduced, and the versatility of the connector holder with respect to the charging connector is improved.

  In the present embodiment, since the cylindrical portion 54 for attaching the connector holder 50 to the bracket 60 has a cylindrical shape, the angle of the pin insertion hole 541 of the cylindrical portion 54 with respect to the longitudinal direction Ds of the connector holder 50 is changed. Thus, the attachment angle α (see FIG. 4) of the connector holder 50 with respect to the frame 21 can be easily changed.

  Moreover, in this embodiment, since the hole for inserting the bolt 63 for attaching the bracket 60 to the frame 21 is the long hole 211 extending in the vertical direction, the attachment position of the connector holder 50 is set in the height direction. It can be adjusted easily.

  Furthermore, in this embodiment, since the connector holder 50 is positioned above the lead-out portion 201 of the charging cable 30 in the stand body 20, the charging cable 30 is not caught by the connector holder 50, and the operability is also good. is there.

  The embodiment described above is described for facilitating the understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

  In the present embodiment, the connector holder 50 has been described as being attached to the stand body 20 of the charging stand 10, but is not particularly limited thereto. For example, the connector holder 50 may be attached to a support stand different from the stand body 20, and the support stand may be installed in the vicinity of the stand body 20.
