When the blade 52 is inserted into the blade insertion slot 25, the blade 52 comes into contact with the contact portions 41C and 42C. When the plug blade 52 is inserted backward from this state, the power supply inner door 41 and the grounding inner door 42 are opposed to the urging forces of the leaf springs 43 to 45 with the bottom portions 29A to 29C as the centers. It turns like a two-dot chain line inside. That is, the power supply inner door 41 and the grounding inner door 42 are each displaced to the open position. Accordingly, the plug blade 52 can be inserted behind the opening / closing portions 41B and 42B.

  On the other hand, when the plug blade 52 is removed from the plug blade insertion port 25, the power source for the power supply is applied by the urging force of the leaf springs 43 to 45 as the rear end portion of the plug blade 52 in the drawing moves forward from the opening / closing portions 41B and 42B. The inner door 41 and the grounding inner door 42 are displaced toward the closed position. When the rear end portion of the plug blade 52 moves forward from the front end surfaces of the open / close portions 41B and 42B, the power inner door 41 and the ground inner door 42 are displaced to the closed positions indicated by solid lines in the drawing. .

The configuration of the plug 50 will be described with reference to FIG.
As shown in FIG. 4A, the plug 50 includes a plug body 51 that is held by a cylindrical user that is long in the front-rear direction X, a plug blade 52 that protrudes forward from the plug body 51, and a plug. And a cable 53 connected to the front end portion of the body 51. The plug blade 52 includes a pair of power plug blades 52A arranged in the left-right direction Y, and a ground pin 52B disposed between the left and right directions Y of the two power plug blades 52A and below the plug blade 52A. . The power plug blade 52A is formed in a flat plate shape. The ground pin 52B is formed in a round pin shape.

  Above the rear end portion of the plug body 51, a position display portion 54 that indicates the positions of the power plug blade 52A and the ground pin 52B is provided. On both side surfaces of the central portion of the plug body 51 in the front-rear direction X, a planar grip portion 55 on which a user's finger is placed is provided. Below the center part of the plug body 51 in the front-rear direction X, a protrusion 56 is provided that protrudes downward in a spherical shape.

  The position display unit 54 is a rectangular protrusion extending along the front-rear direction X. When the position display unit 54 is positioned above the plug 50, the power plug blade 52A is arranged in the left-right direction Y, and the ground pin 52B is disposed below the power plug blade 52A.

  As shown in FIG. 4B, the protrusion 56 includes an inclined portion 57 that is inclined downward toward the front, a top portion 58 that extends forward from the lower end portion of the inclined portion 57, and a front end portion of the top portion 58. And an abutment portion 59 that inclines upward toward the front. A rear recessed portion 57 </ b> A that is recessed upward is provided in the central portion of the inclined portion 57 in the left-right direction Y. A front recessed portion 59 </ b> A that is recessed upward is provided in the central portion of the contact portion 59 in the left-right direction Y. These concave portions 57A and 59A are partitioned by a top portion 58.

  The rear recess 57A connects the rear side surface 57B that inclines so that the width in the left-right direction Y increases toward the rear, and the rear side surface 57B in the left-right direction Y at the front end of the rear side surface 57B, and in the vertical direction Z. And a connecting surface 57C extending along.

  The front recess 59A connects the pair of front side surfaces 59B facing each other in the left-right direction Y and extending along the up-down direction Z, and the front side surface 59B in the left-right direction Y at the rear end portion of the front side surface 59B and in the up-down direction Z. A contact surface 59C extending along the surface.

A mode of connecting the plug 50 to the outlet 10 will be described with reference to FIGS. 5 and 6.
As shown in FIG. 5A, the user adjusts the orientation of the plug 50 so that the position display unit 54 faces upward, and then moves the plug 50 toward the outlet 10. As shown in FIG. 5B, when the protrusion 56 of the plug 50 and the contact protrusion 31 of the support plate 30 are in contact, the support plate 30 is connected to the outlet body 20 and the support plate 30. With the CP as a fulcrum, the front end portion of the support plate 30 is bent so as to be displaced downward. That is, the support plate 30 is elastically deformed downward with the connection position CP as a fulcrum. When the plug 50 is further inserted from this state, as shown in FIG. 5C, after the protruding portion 56 gets over the top of the abutting protruding portion 31, the support plate 30 is displaced upward by the action of the restoring force. To do. At this time, the plug blade 52 is inserted into the plug blade insertion opening 25 (see FIG. 2) and the plug 50 is completely connected to the outlet 10.

  In this state, a slight gap is formed between the inner peripheral surface of the recess 24 and the outer peripheral surface of the plug body 51. Here, the “slight gap” is a gap that is so small that a user's finger cannot enter. Thereby, when inserting the plug 50 so that it may be in the state of FIG.5 (b) from FIG.5 (c), a user's finger | toe enters into the recess 24 is suppressed.

  As shown in FIG. 6, in the state where the plug 50 is connected to the outlet 10, that is, in the state shown in FIG. 5C, the contact protrusion 31 is accommodated in the front recess 59A. Specifically, as shown in FIG. 6A, the contact portion 34 of the contact protrusion 31 is in contact with the contact surface 59C. In addition, as shown in FIG. 6B, the contact protrusion 31 is disposed between the pair of front side surfaces 59B in the left-right direction Y and is close to each front side surface 59B. Specifically, the width T1 in the left-right direction Y of the front side surface 59B is substantially equal to the width T2 in the left-right direction Y of the two contact protrusions 31. Specifically, the width T1 of the front side surface 59B is slightly larger than the width T2 of the contact protrusion 31. Thereby, the support plate 30 fixes the plug 50. Specifically, the abutment protrusion 31 and the protrusion 56 are fixed to each other, thereby preventing the plug blade 52 from being removed from the plug blade insertion port 25 (see FIG. 2).

With reference to FIG. 7, a mode in which the plug 50 is removed from the outlet 10 will be described.
As shown in FIG. 7A, the user presses the front end portion of the support plate 30 downward. In this state, the engagement between the protrusion 56 and the contact protrusion 31 is substantially released. When the user pulls the plug 50 forward, the plug 50 is pulled out from the outlet 10 as shown in FIG. At this time, when the user removes his / her finger from the support plate 30, the support plate 30 is displaced upward by a restoring force.

In the present embodiment, the following effects can be achieved.
(1) In the present embodiment, when the plug 50 is connected to the outlet 10, the protrusion 56 of the plug 50 and the contact protrusion 31 of the support plate 30 abut. Thereby, even if a force is applied inadvertently in the direction in which the plug 50 is removed from the outlet 10 by hooking the cable 53 of the plug 50, the plug 50 can be prevented from being disconnected from the outlet 10.

  By the way, as a fixing portion for preventing the plug from being removed from the outlet, the plug blade is connected to the blade receiving member and then rotated by a predetermined angle so that the projection provided on the blade receiving member is inserted into the through hole provided in the plug blade. Therefore, a structure for preventing the plug from coming off from the outlet can be considered.

  Since the above structure generally assumes a case where the number of times of plug insertion / removal is small, for example, there are many cases where the number of times of plug insertion / removal guarantees about 100 times. Specifically, by inserting the plug blade, the blade receiver is elastically deformed, and the protrusion of the blade receiver enters the through hole of the plug blade. When this elastic deformation of the blade receiver is repeated, the springiness of the blade receiving member is lowered, so that the projection of the blade receiving member does not enter the through hole of the plug blade. As a result, the function of preventing the plug from being disconnected from the outlet may not be achieved while the plug is repeatedly inserted and removed. Therefore, the structure is unsuitable for applications in which the plug is frequently inserted and removed.

  In this respect, in this embodiment, the contact protrusion 31 is provided on the support plate 30 and the protrusion 56 of the plug 50 is fixed to the contact protrusion 31, thereby preventing the plug 50 from being disconnected from the outlet 10. To do. Thereby, the guaranteed frequency | count which can prevent removing a plug from an outlet socket can be increased compared with the retaining structure of the above-mentioned plug blade and blade receiving member.

  Further, in the configuration in which the protruding portion 23 is omitted from the outlet body 20, the wall body 5 and the support plate 30 may interfere with each other, so that the positioning of the outlet 10 with respect to the wall body 5 is difficult. In this respect, in the present embodiment, the outlet 10 can be easily positioned with respect to the wall 5 by inserting the protruding portion 23 into the opening 5A of the wall 5, and therefore the wall 5 and the support plate 30. Can be prevented from interfering with each other. Therefore, the outlet 10 can be easily attached to the wall 5.

  (2) In the present embodiment, when the protrusion 56 contacts the contact protrusion 31, the support plate 30 bends downward about the connection position CP. As a result, the contact protrusion 31 is displaced in a direction away from the protrusion 56. Therefore, since the projection 56 can easily get over the contact projection 31, the plug 50 can be easily inserted into the outlet 10.

  In addition, in a state where the plug 50 is connected to the outlet 10, the support plate 30 bends downward with the connection position CP as a fulcrum when the user presses the support plate 30 downward with a finger. As a result, the contact projection 31 of the support plate 30 moves in a direction away from the projection 56 of the plug 50, so that when the plug 50 is removed from the outlet 10, the contact projection 31 and the projection 56 are mutually connected. Interference can be suppressed. Thereby, since it is possible to omit providing a dedicated mechanism for moving the contact protrusion 31 in the direction away from the protrusion 56 on the support plate 30, the support plate 30 can be simplified. it can.

  (3) In the present embodiment, when the plug 50 is not connected to the outlet 10, the power inner door 41 and the ground inner door 42 cover the plug blade insertion opening 25, respectively. Therefore, it is possible to prevent foreign matters such as insects from entering the outlet 10 through the plug blade insertion opening 25.

  (4) In the present embodiment, the recess 24 is provided inside the projecting portion 23, so that the user's hand enters the recess 24 when the user connects the plug 50 to the outlet 10. Can be suppressed.

  (5) In this embodiment, the protrusion 10 is inserted into the opening 5 </ b> A of the wall 5, thereby positioning the outlet 10 with respect to the wall 5. That is, the opening 5A serves to both position the outlet 10 and expose the plug blade insertion opening 25 to the outside. Therefore, a dedicated opening hole for inserting the protruding portion 23 into the wall body 5 can be omitted, so that the shape of the wall body 5 can be simplified.

  (6) In this embodiment, it is formed so that the upper part of the projecting portion 23 has a curved shape and the lower part has a rectangular shape in plan view as viewed from the front. That is, the shape of the protruding portion 23 is asymmetrical in the vertical direction. Thereby, the direction of the outlet 10 can be easily visually recognized in the up-down direction Z. Therefore, the worker can easily perform the work of attaching the outlet 10 to the wall body 5.

  (7) In the present embodiment, the contact protrusion 31 of the support plate 30 is accommodated in the front recess 59 </ b> A of the protrusion 56 of the plug 50 in a state where the plug 50 is connected to the outlet 10. Thereby, the movement to the left-right direction Y of the plug 50 can be controlled.

  (8) According to the present embodiment, the position of the plug blade 52 can be confirmed by providing the plug 50 with the position display unit 54. Thereby, the operation | work which confirms the arrangement position of the plug blade 52 by an operator looking directly at the plug blade 52 can be abbreviate | omitted.

The support plate 30 has a second position for engaging the contact projection 31 with the projection 56 of the plug 50 as shown in FIG. 9 (a) and the support plate 30 as shown in FIG. 9 (b). The surface can be displaced between a first position where the surface contacts the front surface 23 </ b> A of the protrusion 23. That is, the support plate 30 can be rotated between the open position and the closed position with the shaft 61 as the rotation center. Hereinafter, the rotation direction of the support plate 30 is referred to as “opening / closing direction W”, the opening direction of the support plate 30 is referred to as “opening direction”, and the closing direction of the support plate 30 is referred to as “closing direction”.

  As shown in FIG. 9 (c), the support plate 30 is movable with the one end of the support plate 30 as a rotation center with respect to one end attached to the support portion 21A of the support plate 30 in the closed position. The tip part 74 which is an end protrudes to the other end side from the other end part of the protruding part 23. That is, when the support plate 30 is in the closed position, the upper end portion of the support plate 30 protrudes above the upper end portion of the protruding portion 23.

  With reference to FIG. 10, the aspect which connects the plug 50 to the electrical outlet 10 is demonstrated. In FIG. 10, the internal structure of the outlet 10 is omitted and only the door body 31 is shown as a cross-sectional structure. Further, the cable 53 of the plug 50 is omitted.

  As shown in FIG. 10A, the user displaces the support plate 30 from the closed position so that the support plate 30 is in the open position (hereinafter, “open operation”). In the state of the support plate 30, the plug 50 is brought into contact with the support plate 30 so that the protrusion 56 of the plug 50 is accommodated in the recess 71 of the support plate 30 as shown in FIG.

  In this state, the plug blade 52 is disposed at a position corresponding to the front-rear direction X with respect to the plug blade insertion opening 25 (see FIG. 3). Specifically, the tip of the ground pin 52B is inserted into the ground insertion port 25B (see FIG. 3). On the other hand, the power plug blade 52A is arranged in front of the power supply insertion port 25A (see FIG. 3). In this state, when the plug 50 is inserted backward, the plug blade 52 is inserted into the plug blade insertion port 25.

  In addition, the width in the left-right direction Y of the protrusion 56 is substantially equal to the width in the left-right direction Y of a portion in front of the contact protrusion 31 of the recess 71. Specifically, the width of the portion of the recess 71 is slightly larger than the width of the protrusion 56. Accordingly, when the plug 50 is about to move in the left-right direction Y with respect to the support plate 30 in a state where the protrusion 56 is accommodated in the recess 71, the protrusion 56 is formed on the side surface of the recess 71 in the left-right direction Y. Contact. As a result, the movement of the plug 50 in the left-right direction Y with respect to the support plate 30 is restricted.

  As shown in FIG. 10 (c), the support plate 30 is moved to the position shown in FIG. 10 (a) by moving the plug 50 rearward to bring the protrusion 56 into contact with the contact protrusion 31 of the support plate 30. It rotates so that it may become a position of an open direction rather than the open position shown. As shown in FIG. 10D, after the protrusion 56 has climbed over the top of the contact protrusion 31, the support plate 30 is rotated in the closing direction by the urging force of the spring member 62 (see FIG. 8). The rotation stops when the contact protrusion 31 is in contact with the plug body 51. At this time, the plug blade 52 is inserted into the plug blade insertion opening 25 (see FIG. 2) and the plug 50 is completely connected to the outlet 10.

  With reference to FIG. 11, a mode in which the plug 50 is removed from the outlet 10 will be described. In FIG. 11, the internal structure of the outlet 10 is omitted and only the door body 31 is shown as a cross-sectional structure. Further, the cable 53 of the plug 50 is omitted.

  As shown in FIG. 11A, the user moves the support plate 30 in the opening direction. In this state, the protrusion 56 and the contact protrusion 31 are disengaged. Then, as shown in FIG. 11 (b), when the user pulls the plug 50 forward, the plug 50 is pulled out from the outlet 10 as shown in FIG. 11 (c). At this time, when the user removes his / her finger from the support plate 30, the support plate 30 is rotated to the closed position by the urging force of the spring member 62 (see FIG. 8).

According to this embodiment, in addition to the effects (1) to (8) of the first embodiment, the following effects can be achieved.
(9) In this embodiment, since the support plate 30 can rotate between the closed position and the open position, the support plate 30 can be folded when the plug 50 is not inserted into the outlet 10. Therefore, it is possible to prevent the support plate 30 from being damaged by an inadvertent external force applied to the support plate 30.

  (10) In the present embodiment, when the support plate 30 is in the closed position, the distal end portion 74 of the support plate 30 protrudes upward (centrifugal side) from the protruding portion 23. This makes it easier to hook the user's finger on the tip 74. Therefore, the user can easily perform the opening operation.

  (11) In the present embodiment, the curved recess 72 is provided at the tip 74 of the support plate 30. This makes it easier for the user's finger to be hooked on the curved recess 72. Therefore, the user can perform the opening operation more easily.

  (12) In the present embodiment, the recess 71 is provided in the support plate 30. Therefore, when the plug 50 is inserted into the outlet 10, the projection 56 of the plug 50 is accommodated in the recess 71, whereby the plug blade 52 can be positioned in the left-right direction Y with respect to the plug blade insertion opening 25.

  (13) In the present embodiment, the shaft 61 is positioned in front of the front surface 23 </ b> A of the protruding portion 23, that is, the center of rotation of the support plate 30 is positioned in front of the protruding portion 23. Thereby, the shape for exclusive use for the surface of the support plate 30 to contact | abut with the front surface 23A of the protruding part 23 can be abbreviate | omitted. Therefore, the shape of the support plate 30 can be simplified.

  (14) As shown in FIG. 19, when the outlet body 110 is not provided with a protruding portion, it is difficult to position the outlet 100 with respect to the wall body 5. Therefore, when the outlet 100 is mounted at a position shifted upward with respect to the desired mounting position of the wall body 5, the support plate 120 comes into contact with the wall body 5. As a result, the aesthetics of the outlet 100 in a state where the outlet 100 is assembled to the wall 5 is deteriorated.

  Further, when the outlet 100 is attached at a position shifted downward with respect to a desired attachment position of the wall body 5, the attachment portion 130 serving as a center for rotating the support plate 120 in the outlet 100 comes into contact with the wall body 5. End up. As a result, the support plate 120 cannot be rotated from the closed position toward the open position.

  In this respect, in the present embodiment, since the outlet 10 is positioned with respect to the wall 5 of the charging stand 1 by the protrusion 23, the outlet 10 can be easily positioned at a desired mounting position of the wall 5. Thereby, position shift of outlet 10 to wall 5 can be controlled. As a result, it is possible to suppress a decrease in aesthetics of the outlet 10 when the outlet 10 is assembled to the wall body 5.

  In addition, since the outlet 10 is positioned with respect to the wall 5, the support portion 21 </ b> A and the shaft insertion portion 73 can be disposed in the opening 5 </ b> A of the wall 5. Therefore, it is possible to suppress the support plate 30 from being unable to rotate from the closed position toward the open position when the support portion 21A and the shaft insertion portion 73 are in contact with the wall body 5.
