It has support holes 47 . In this way, it is preferable to have the support portion 81 on the upper surface side of the connector housing portion 2 so that the support portion 81 is suspended and supported.

The cover member 43 of the embodiment has a substantially L-shape in a side view in order to cover the combined mounting member 41 and support member 42, and has a back side that avoids a string or band passed through the mounting member 41. A notch 48 is provided for this purpose. Further, on the front side of the cover member 43 of the example shown in FIG. 6, a convex portion 49 is formed that abuts on the case portion 20 in order to restrict the rotation of the case portion 20 in the left-right direction.

The case part 20 of the embodiment includes a left side case 201 forming a left side shape and a right side case 202 forming a right side shape. is screwed in.

8 to 10, the left case 201 and the right case 202 sandwich the rotating member 82 on their upper sides. The rotating member 82 is composed of a disc portion 83 and a shaft portion 84, and the upper surface of the disc portion 83 and the periphery of the shaft portion 84 are coated with resin or the like to facilitate rotation of the rotating member 82. In addition, the rotating member 82 is supported by inserting the bolt that forms the support portion 81 from below into the shaft portion 84 and fixing the bolt to the support hole 47 of the support member 42 of the mounting portion 40. It supports the case portion 20 that clamps the rotating member 82 .

A bearing 21 for receiving the shaft portion 11 of the holding portion 10 is provided inside the left case 201 and the right case 202 . In addition, inside the left case 201 and the right case 202, a plurality of restricting portions that restrict the rotation of the holding portion 10 are provided. As can be understood from FIG. 10, the first restricting portion 22 provided in the lower portion of the case portion 20 is arranged such that the opening portion 12 side of the holding portion 10 faces upward when the charging connector 91 is not held. to restrict rotation. Further, as can be understood from FIG. 11 , the second restricting portion 23 provided on the upper portion of the case portion 20 is arranged such that the opening portion 12 side of the holding portion 10 faces downward when the charging connector 91 is held. Restrict turning towards.

By the way, a gap is provided between the bearing 21 of the case portion 20 and the shaft portion 11 of the holding portion 10 inserted therein in order to smoothly rotate the holding portion 10 in the vertical direction. However, due to the presence of the gap, when inserting charging connector 91 into holding portion 10 , holding portion 10 is not fixed, which may cause a problem of difficulty in inserting charging connector 91 . Therefore, in the embodiment, when the charging connector 91 is inserted, the convex portion 24 is provided inside the case portion 20 so that the back surface of the holding portion 10 abuts to suppress the rotation of the holding portion 10 . By providing the convex portion 24 , it is possible to facilitate the insertion of the charging connector 91 into the holding portion 10 . The convex portion 24 is provided near the mating surfaces of the left case 201 and the right case 202 inside the case.

12 to 16, the shaft portion 11 is provided with a convex restricting portion 18, and the bearing 21 is provided with a convex restricting portion . The gap between the restricting portion 28 provided on the case portion 20 and the restricting portion 18 provided on the holding portion 10 allows the charging connector 91 to be connected to the holding portion 10 more than the state where the charging connector 91 is not connected to the holding portion 10 . It is configured to be narrower after the holding portion 10 has moved. Therefore, the state in which the charging connector 91 is inserted into the holding portion 10 and the holding portion 10 is rotated suppresses the rattling of the holding portion 10 more than the state in which the charging connector 91 is not inserted in the holding portion 10. .

The restricting portion 28 of the embodiment has a shape having a slope that gradually reduces the gap as it rotates from the pre-rotation position to the post-rotation position, but it may protrude only to the post-rotation position. Contrary to this example, the regulating portion 18 may have a sloped shape so that the gap gradually decreases as it rotates from the pre-rotation position to the post-rotation position.

A convex portion 25 is provided on the outside of the left case 201 and the right case 202 . As shown in FIG. 17, the convex portion 25 provided on the outside of the case abuts against the convex portion 49 on the inner side of the mounting portion 40 when rotating in the left-right direction, thereby restricting further rotation in the left-right direction. do. It should be noted that the rotation in the opposite direction may be restricted by getting over the convex portion 49 inside the mounting portion 40 .

As can be seen from FIG. 18, the holding portion 10 of the embodiment has an opening 12 for inserting the charging connector 91 on the front side, and inserts into the bearings 21 of the case portion 20 on both left and right sides. It has a shaft portion 11 that is Moreover, above the opening 12, there is a fitting portion 13 that fits into a claw portion provided above the charging connector 91 to prevent the charging connector 91 from coming off.

As understood from FIGS. 18 to 20, a slit 14 is provided in the rear portion of the opening 12 so that foreign matter can be discharged from the rear side. In addition, a rib 15 protruding forward is provided on the upper portion of the slit 14 in order to prevent water from entering the terminal portion of the inserted charging connector 91 or the like.

As can be seen from FIG. 19, the holding part 10 has a projecting part 16 on the back side. The projecting portion 16 of the embodiment has a substantially T-shape that is inverted upside down. The upper surface of the side extending in the left and right direction on the lower side of the projecting portion 16 abuts on the second restricting portion 23 of the case portion 20, thereby allowing the holding portion 10 to move downward while the charging connector 91 is held. It regulates rotation. In addition, the lower surface of the lower side of the projecting portion 16 that extends in the left and right direction contacts the first restricting portion 22 of the case portion 20, so that the upper surface of the holding portion 10 in the state in which the charging connector 91 is not held. It regulates the rotation in the direction.

21 to 23, between the projecting portion 16 provided on the outer surface of the holding portion 10 as a restricting portion and the second restricting portion 23 provided on the inner surface of the case portion 20. is narrower after charging connector 91 is connected to holding portion 10 and holding portion 10 moves than when charging connector 91 is not connected to holding portion 10 . Therefore, the rattling of the holding portion 10 can be suppressed more when the charging connector 91 is inserted into the holding portion 10 and the holding portion 10 is rotated than when the charging connector 91 is not inserted into the holding portion 10 .

More specifically, the vertically extending sides of the protruding portion 16 provided on the back surface of the holding portion 10 in the embodiment have a tapered shape in which the width becomes narrower toward the tip. On the other hand, second restricting portions 23 provided at the rear portion of the case portion 20 are provided at corresponding positions of the left case 201 and the right case 202, respectively. At the pre-rotation position, the protruding portion 16 is positioned away from the second restricting portion 23, and the distance between them decreases as the protruding portion 16 rotates. From the middle stage of the movement, the protruding portion 16 is sandwiched between the second restricting portions 23, but the gap between the tapered protruding portion 16 and the second restricting portion 23 becomes smaller, and the gap at the post-rotation position becomes smaller. becomes the smallest. The shape of the protruding portion 16 is not limited to a tapered shape, and may be any shape as long as the gap at the post-rotation position is the smallest.

In the above example, the vehicle charging connector holding device 1 includes the mounting portion 40, the case portion 20, and the holding portion 10. Alternatively, the holding portion 10 may be supported by the mounting portion 40 without the case portion 20 . Alternatively, the mounting portion 40 may be omitted, and the case portion 20 and the holding portion 10 alone may be configured so as to be directly supported by the eaves 98 of the house, the roof of the carport, or the ceiling (FIG. 24). reference).

By the way, it is also possible to provide a rotation restricting mechanism capable of both restricting the lateral rotation of the connector accommodating portion 2 and releasing the restriction. In this way, it is possible to cope with the case where it is desired to restrict the rotation in the horizontal direction and the case where the restriction is desired to be released. For example, in order to restrict the lateral rotation of the connector accommodating portion 2, the connector accommodating portion 2 may be held to prevent or restrict the rotation. In the examples shown in FIGS. 25 to 33, the support member 42 has a structure in which a regulation hole 88 is provided. Rotation of the case portion 20 is restricted by fitting a restriction pin 89 provided on the case portion 20 side into the restriction hole 88 .

In the embodiment, the case portion 20 is provided with a vertically movable restricting pin 89 . In the embodiment, when the charging connector 91 is inserted into the holding portion 10 and the rear side of the holding portion 10 moves upward, the holding portion 10 can push up the regulation pin 89 . When the regulating pin 89 is fitted into the regulating hole 88, the rotation of the case portion 20 is regulated. That is, the lateral rotation of the connector accommodating portion 2 is restricted. In some cases, even if the regulating pin 89 is lifted upward, the regulating pin 89 may not fit into the regulating hole 88. However, if the case portion 20 is rotated in this state, the regulating pin 89 may fit into the regulating hole 88. can.

Further, in the embodiment, the center of gravity of the holding portion 10 is positioned behind and below the shaft portion 11 of the holding portion 10 . Therefore, when the charging connector 91 is removed from the holding portion 10, the rear side of the holding portion 10 moves downward. As a result, the force pushing up the regulating pin 89 is released, so that the regulating pin 89 is pulled out of the regulating hole 88, and the restriction on the lateral rotation of the case portion 20 is automatically released. By removing the charging connector 91 from the holding portion 10 in this way, the restriction on the lateral rotation of the connector housing portion 2 is released, thereby enhancing the convenience.

In the embodiment, since three regulation holes 88 are provided so as to be shifted by 90 degrees around the support hole 47, the rotation of the case portion 20 can be regulated at positions shifted by 90 degrees (Fig. 31 to Fig. 31). 33). The number of regulation holes 88 may be further increased or decreased.

Although the present invention has been described above using the embodiments as examples, the present invention is not limited to the above-described embodiments, and various aspects are possible. For example, in the vehicle charging connector holding device, the case portion rotates horizontally and the holding portion rotates vertically, but the case portion rotates vertically and the holding portion rotates horizontally. may

Alternatively, one of the case portion and the holding portion (for example, only the holding portion) may rotate in the left-right direction and the up-down direction. In order to do so, for example, the rotating member of the case portion may be spherical and sandwiched between the left case and the right case. This allows the case portion to rotate in various directions with respect to the mounting portion.

After the connector accommodating portion rotates in the left-right direction, the rotating member may be made difficult to rotate or prevented from rotating in the opposite direction by abutting or fitting the restricting member on the rotating member of the case portion. By inserting the regulating member through an opening provided above the case portion, the regulating member may come into contact with the rotating member.

Also, the regulating member can be provided on the holding portion. When the holding portion holds the charging connector, the opening of the holding portion rotates downward, but the back side rotates upward. Therefore, it is difficult to rotate the rotating member by providing a restricting member above the back side so that the restricting member comes into contact with the lower surface of the rotating member while the charging connector is held by the holding portion. is also possible.

The configuration for adjusting the gap between the regulating portions before and after the charging connector is connected to the holding portion includes “the inner surface side portion of the case portion and the left and right side portions of the holding portion” and “the inner lower portion of the case portion and the holding portion.” provided on the inner surface of the case part and the outer surface of the holding part, such as "lower part", and provided in any place and in any shape as long as the gap between the restricting parts is smaller after rotation than before rotation. may be
