The main body 2 outputs electric power for charging the storage battery 82, and the storage battery 82 is used as a power source for the movable body 8 (see FIG. 2). The plug 3 is configured to be connectable to the charging port of the battery 82. When the plug 3 is connected to the charging port of the battery 82, the body outputs electric power for charging, so that the electric power can be supplied to the battery 82 via the plug 3. When the plug 3 is not in use, the holding tool 54 holds the plug 3.

The movable body 8 includes a storage battery 82 and moves by using electric energy charged in the storage battery 82. In this embodiment, the movable body 8 is an electric vehicle, but in the present disclosure, for example, it may be Plug-in hybrid vehicles, electric pallets, electric two-wheeled vehicles, electric tricycles, four-wheeled off-road vehicles, etc. that operate by combining engine output and motor output. The "electric two-wheeled vehicle" here includes locomotives, electric locomotives, and electric-assisted locomotives. "Electric tricycles" include electric vehicles and electric-assisted tricycles. The movable body 8 also includes flying bodies, such as aircraft and aircraft.

As shown in FIG. 1, the main body 2 is attached to the mounting surface 71. The "mounting surface 71" referred to in the present disclosure means the surface to which the body 2 of the power supply device 1 is attached, and examples thereof may include the wall of a building, the surface of a column, and the attachment surface of a dedicated seat frame. Examples of buildings with installation surfaces 71 include homes, parking lots, offices, hospitals, welfare facilities, art galleries, museums, factories, warehouses, sports facilities, shops, schools, halls, studios, hotels, restaurants, transportation facilities, and agriculture facility. The mounting surface 71 may be along a vertical plane or may be inclined from the vertical plane. The mounting surface 71 is not limited to a flat surface, but may be a rough surface.

As shown in FIG. 3, the plug 3 includes: a plug body 31 with a handle 32; and a power terminal 38 that can be connected to a charging port. As described above, when the plug 3 is not in use, the plug 3 is held by the holder 54.

Hereinafter, the power supply device 1 according to this embodiment will be described in detail. In the following description, unless otherwise specified, the mounting surface 71 is described as a vertical plane, and the direction in which the mounting surface 71 faces (the direction orthogonal to the mounting surface 71 and away from the mounting surface 71) is defined as the forward direction. The direction opposite to the forward direction is called the backward direction. The forward and backward directions can be collectively referred to as the "front and rear directions". The two opposite directions that are orthogonal to the front-rear direction and extend along the horizontal plane are defined as the "left-right direction".

However, the definition of these directions is not intended to limit the use of the power supply device 1. In addition, the arrows indicating various directions in the drawings are shown for illustrative purposes only and are intangible.

As shown in FIG. 2, the power supply device 1 according to this embodiment is controlled by the control device 9. The control device 9 is a device different from the power supply device 1 and is a device for controlling various devices (including facilities) to be controlled. For example, the control device 9 is installed in a house, and the power supply device 1 is installed outside the house, but the control device 9 and the power supply device 1 can be installed at the same location. The control device 9 will be used to indicate the charging on The initial “charging command” and the “stop command” used to instruct charging to stop are output at least to the power supply device 1 according to this embodiment, so as to control the power supply device 1 and control the charging of the storage battery 82 through the power supply device 1.

The control device 9 and the power supply device 1 are configured to communicate with each other. The term "communicable" as used herein means that information can be directly or indirectly exchanged through a network, a repeater, etc. through an appropriate communication framework (such as a wired communication framework and a wireless communication framework). That is, the control device 9 and the power supply device 1 can exchange information with each other. In this embodiment, the control device 9 and the power supply device 1 can communicate with each other bidirectionally, and information transmission from the control device 9 to the power supply device 1 and information transmission from the power supply device 1 to the control device 9 are both possible.

The control device 9 according to this embodiment is configured to communicate with an information terminal 91 (such as a tablet, a smart phone, etc.) owned by a user, and can control the power supply device 1 based on an electrical signal from the information terminal 91.

As shown in FIG. 1, the power supply device 1 according to this embodiment includes a main body 2, a plug 3, a power cable 4, a plug holder 5, a drawing part 61, and a cable support 62.

(1.2.2) Ontology

The main body 2 is a part of a storage battery 82 for outputting rechargeable electric power to the movable body 8. In this embodiment, the main body 2 is connected to a power source (for example, a commercial AC power source) via a power connector (not shown) and receives electric power. The main body 2 includes a charging unit 21 (FIG. 2) and a casing 22 accommodating the charging unit 21.

The charging unit 21 outputs chargeable power to the storage battery 82 of the movable body 8. As shown in FIG. 2, the charging unit 21 includes a communication unit 211, a power control unit 212, a relay 213, a protection circuit 214, and a vehicle communication unit 215.

The communication unit 211 is configured to directly or indirectly communicate with the control device 9 via a network, a repeater, and the like. As the communication unit 211 and the control device 9 (specifically, the communication of the control device 9 The communication structure between units) adopts an appropriate communication structure such as a wireless communication structure or a wired communication structure. In this embodiment, the communication architecture between the communication unit 211 and the control device 9 is, for example, a wired communication architecture based on a communication standard such as a wired LAN (Local Area Network). The communication protocol in the communication between the communication unit 211 and the control device 9 is, for example, Ethernet (registered trademark), ECHONET Lite (registered trademark), etc.

The power supply control unit 212 is configured to control the power supply from the power supply device 1 to the movable body 8. Here, the power supply control unit 212 controls the power supply to the movable body 8 by driving the relay 213 according to the charging instruction and the stop instruction from the control device 9. Basically, when the communication unit 211 receives a charging instruction from the control device 9, the power supply control unit 212 turns on the relay 213 (conducting state), and allows the power supply from the power supply device 1 to the movable body 8 to charge the storage battery 82 . On the other hand, when the communication unit 211 receives a stop instruction from the control device 9, the power supply control unit 212 turns off the relay 213 (off state), and stops the power supply from the power supply device 1 to the movable body 8, thereby stopping the Charging of battery 82.

However, the control device 9 only controls the charging of the storage battery 82. For example, in a state where the storage battery 82 cannot be charged (for example, the storage battery 82 is in a fully charged state), the storage battery 82 will of course not be charged. Similarly, when the plug 3 is not connected to the movable body 8 and the power supply device 1 and the movable body 8 are not electrically connected, the battery 82 will naturally not be charged. Therefore, in a state where the storage battery 82 cannot be charged in this way, even if the charging command is received from the control device 9, the power supply control unit 212 will not turn on the relay 213, and the connection from the power supply device 1 to the movable body 8 is not allowed. electricity supply.

In this embodiment, the power control unit 212 mainly includes a computer system including a memory and a processor. That is, the function of the power control unit 212 is realized by a processor that executes a program recorded in the memory of the computer system. The program can be pre-recorded in the memory and can be passed through the telecommunication line It can be provided via the Internet (such as the Internet), or can be provided by recording in a non-transitory recording medium (such as a memory card).

The relay 213 is provided in the electric power supply path leading to the storage battery 82. Specifically, the relay 213 is provided between the power input side connection terminal of the power supply device 1 and the connection terminal of the power cable 4. Therefore, when the relay 213 is turned on (in its conducting state), power can be supplied from a power source (for example, an electric power system or a photovoltaic power generation facility) to the storage battery 82 of the movable body 8. On the other hand, when the relay 213 is turned off (in its off state), power is not supplied to the storage battery 82 of the movable body 8 from the power source. The relay 213 can be controlled by the power control unit 212, and can be a mechanical relay with mechanical contacts or a semiconductor relay without mechanical contacts. In this embodiment, for example, the relay 213 is realized by a mechanical relay.

The protection circuit 214 is a circuit for protecting the power supply device 1 and the movable body 8 by turning off the relay 213 when an abnormality (such as leakage current or overcurrent) is detected, for example. In addition to the relay 213, the protection circuit 214 may also include an element for cutting off the electric power supply to the movable body 8.

The vehicle communication unit 215 is configured to directly or indirectly communicate with the movable body 8 via a network, a repeater, and the like. As the communication architecture between the vehicle communication unit 215 and the movable body 8, an appropriate communication architecture such as a wireless communication architecture or a wired communication architecture is adopted. In this embodiment, the vehicle communication unit 215 can communicate based on at least a CPLT (Control Guide) signal to check the connection between the power supply device 1 and the movable body 8, the state of the movable body 8, and the like.

In the power supply device 1, as described above, the main body 2 is electrically connected to the plug 3 via the power cable 4. In the power supply device 1, when the plug 3 is connected to the movable body 8, the main body 2 is electrically connected to the movable body 8 via the power cable 4. Therefore, the main body 2 can supply electric power to the movable body 8 (the storage battery 82) via the power cable 4, and can communicate with the movable body 8.

The housing 22 is a box housing the charging unit 21. As shown in FIG. 1, in this embodiment, the housing 22 includes a housing body 23 and a cover portion 24.

In this embodiment, the holder 54 is attached to the holder fixing surface 522 of the frame 52 and is fixed to the holder fixing surface 522. The holding tool 54 includes a fixing plate 55, a fixing column 56 integrally provided on the fixing plate 55, a guiding part 57, and an engaging member 58 including a hooking hole 581.

The fixing plate 55 is fixed to the fixing surface 522 of the holder. In this embodiment, the outer shape of the fixing plate 55 is a rectangular plate shape. A plurality of through holes 551 are formed on the four corners of the fixing plate 55, and the fixing plate 55 is fixed to the frame 52 by screwing screws into the fixing surface 522 of the holder through the through holes 551.

The holding cylinder 56 is the part into which the plug 3 is inserted. The central axis 561 of the holding column 56 (see FIG. 5B) is orthogonal to the fixing plate 55. The end of the holding column 56 close to the fixing plate 55 is closed by the fixing plate 55, thereby forming a hollow cylindrical shape at the bottom. The holding cylinder 56 is a circular hollow cylinder in this embodiment. The central axis 561 of the holding column 56 (see FIG. 5B) is orthogonal to the holding fixture fixing surface 522.

The guiding part 57 is a part for guiding the plug 3 to be inserted into the holder 54 in one direction. The guide portion 57 is in contact with a part of the plug 3 to restrict the movement of the plug 3 in a direction other than the one direction (a direction intersecting the one direction). In this embodiment, the guiding direction of the guiding portion 57 is inclined with respect to the attachment surface 72. Therefore, in this embodiment, the guiding direction of the guiding portion 57 is also inclined with respect to the mounting surface 71.

In this embodiment, the guiding portion 57 is a groove formed in a part of the holding column 56, and the groove is parallel to the central axis 561 of the holding column 56. Therefore, in this embodiment, the "one direction" is parallel to the central axis 561 of the holding column 56 and is inclined with respect to the mounting surface 71, so as to extend downward and downward when extending outward with respect to the main body 2 in the left-right direction. Front extension. However, the “one direction” referred to in the present disclosure does not need to extend downward and forward when it extends outward relative to the main body 2 in the left-right direction, but may extend in a predetermined direction. Here, "predetermined direction" means from any position towards The direction of the position where the plug 3 is appropriately held with respect to the holding tool 54. In this embodiment, the "one direction" is along a straight line, but in the present disclosure, the "one direction" may be along a curve, such as a part of a spiral, an arc, etc.

Here, although the guiding portion 57 is formed in a part of the holding column 56 in this embodiment, for example, a guide parallel to the central axis 561 of the holding column 56 can be provided at a position different from the holding column 56. Guide rail, or a guide pin can be provided. Furthermore, the inner peripheral surface of the holding column 56 can be used as the guiding part 57, and the holding column 56 can also be used as the guiding part 57.

The engaging member 58 is a member having a hook hole 581 through which the hook portion 34 of the plug 3 is hooked. In this embodiment, the engaging member 58 is arranged on the holding cylinder 56 and is connected to the fixing plate 55 with screws. Therefore, the engaging member 58 is fixed to the holding column 56.

In this embodiment, the position where the engaging member 58 is set can be any position corresponding to the hooking portion 34 when the plug 3 is inserted into the holding post 56, and the engaging member 58 can be set in front of the holding post 56. Behind, or below. Furthermore, the hook hole 581 is a recess with a bottom surface in this embodiment, but it can also be a through hole.

As shown in FIG. 5A, the plug 3 is held by the plug holder 5. The user extends the guided portion 36 (the elongated protrusion 361) of the plug 3 along the guiding portion 57, and moves the plug 3 toward the holder 54 of the plug. Then, the plug 3 is guided by the guide part 57 to move in one direction, and the hook part 34 is hooked in the hook hole 581. Therefore, the plug 3 is held by the holder 54.

In this embodiment, the direction in which the guiding part 57 guides the plug 3 is inclined with respect to the mounting surface 71. Therefore, as shown in FIG. 6, the center 38c of the distal end of the power supply terminal 38 (see FIG. 3B) and the center 321 of the end of the handle 32 opposite to the terminal 38 on the longitudinal axis (hereinafter referred to as the rear end) The straight line S2 (sometimes referred to as the second straight line S2) is inclined with respect to the mounting surface 71. Therefore, even if the user holds the hand The handle 32 and the plug 3 into the holder 54 can also reduce the interference between the hand holding the handle 32 and the mounting surface 71. In FIG. 6, θ2 represents the angle of the straight line S2 with respect to the mounting surface 71. θ2 is, for example, greater than 0° and less than 90°. In particular, θ2 may be greater than or equal to 5° and less than or equal to 45°. Furthermore, θ2 may be greater than or equal to 10° and less than or equal to 20°.

The "center 38c of the distal end of the power terminal 38" in the present disclosure means the centroid of the distal surface of the power terminal 38. Therefore, in this embodiment, as shown in FIG. 3B, the center of the distal end of the power terminal 38 is the center between the distal surfaces of the two terminals 38a and 38b of the power terminal 38. If the power terminal 38 has three terminals, the center of the distal end of the power terminal 38 is the centroid of a pattern (triangle) formed by connecting the centers of the distal surfaces of the respective terminals. When the plural terminals are arranged in a straight line, the center of the distal end of the power terminal 38 is the center of a line segment formed by connecting the centers of the distal surfaces of the respective terminals. In the present disclosure, "the center 321 of the rear end of the handle 32" means the centroid of the outer shape of the rear end surface of the handle 32.

When the plug 3 is held by the holding tool 54, as shown in FIG. 6, the plug 3 is positioned between the first virtual plane H1 and the second virtual plane H2. The first virtual plane H1 is a virtual plane including the surface of the body 2 opposite to the mounting surface 71 (ie, the front surface 283). The second virtual plane H2 is a virtual plane including the mounting surface 71. In this embodiment, the second virtual plane H2 is the mounting surface 71 and is tangible. The first virtual plane H1 and the second virtual plane H2 are parallel in this embodiment, but they may also be non-parallel. When the plug 3 is positioned between the first virtual plane H1 and the second virtual plane H2, the storage performance when the plug 3 is held by the holder 54 can be improved.

Here, the term "located between" in the present disclosure includes the case where the first virtual plane H1 (or the second virtual plane H2) and the surface of the plug 3 are located in the same plane. However, in this embodiment, the plug 3 is close to the first virtual plane H1 and away from the second virtual plane H2.

Furthermore, in this embodiment, as shown in FIG. 7, the direction in which the guide portion 57 guides the plug 3 is inclined, so as to extend toward the body 2 from the plug holder 5 in the left-right direction.上extended. Therefore, when the user grasps the handle 32 and moves the plug 3 toward the holder 54 of the plug, the distal end 33 of the plug 3 can be moved when it is located above the handle 32. Therefore, the plug 3 can be moved without lifting the excessive power cable 4, and thus the ease of use can be improved.

At this time, in the state where the plug 3 is held by the holder 54, the second straight line S2 is inclined so as to extend upward as it extends from the plug holder 5 toward the main body 2. Therefore, the power cable 4 can be hung downward along the handle 32 of the plug 3, and the storage performance of the power cable 4 can be improved. The power cable 4 is supported by a cable support 62 provided on the bottom plate 232 of the main body 2.

(1.2.6) Withdrawal part and cable support

As shown in FIG. 1, the drawing-out part 61 is a part for drawing the power cable 4 connected to the charging unit 21 in the housing 22 to the outside of the housing 22. As shown in FIG. 5B, the withdrawing part 61 is provided on the bottom plate 232 of the housing 22. As shown in FIG. 5B, the shape of the extraction portion 61 is a cylindrical shape protruding downward from the bottom plate 232. However, the extraction part 61 may be a through hole formed in the bottom plate 232. The power cable 4 is passed through the drawing part 61 and the power cable 4 is led out from the bottom surface 27 of the body 2.

The center of the extraction portion 61 is located behind the center of the main body 2 in the front-rear direction. However, the extraction portion 61 may be provided at an arbitrary position in the front-rear direction with respect to the bottom surface 27 of the body 2.

The cable support 62 supports part of the power cable 4. In this embodiment, the cable support 62 is located on the side of the center of the extraction portion 61 opposite to the installation surface 71 in a direction orthogonal to the installation surface 71. That is, the cable support 62 is provided in front of the center of the withdrawing part 61. In this embodiment, "the cable support is located on the side opposite to the installation surface 71 from the center of the extraction portion 61 in a direction orthogonal to the installation surface 71" means: the connection portion 621 of the cable support 62 Between base plate 232 The boundary of is located on the side of the center of the extraction portion 61 opposite to the mounting surface 71. In this embodiment, the connecting portion 621 is linear along the vertical direction. However, in the disclosure herein, it may be inclined with respect to the vertical plane or formed in a stepped shape. Even in this case, it is still sufficient to position the upper end of the connecting portion 621 in front of the center of the withdrawing portion 61.

The cable support 62 includes a connecting part 621, a supporting part 622, and a restricting part 623. The connecting part 621 is a part that interconnects the supporting part 622 and the bottom plate 232. In this embodiment, the connecting portion 621 is formed by a pair of rods extending downward from the bottom plate 232, but can be inclined with respect to the vertical plane as described above. The supporting part 622 is a part supporting a part of the power cable 4. In this embodiment, the supporting part 622 extends forward from the lower end of the connecting part 621. The restricting portion 623 restricts the movement of the power cable 4 supported by the supporting portion 622. The restricting portion 623 protrudes upward from the front end of the supporting portion 622. As shown in FIG. 5B, the front end of the restricting portion 623 is tied on the same plane as the front surface 283 of the body 2. In short, the front end of the restricting portion 623 is positioned on the same plane as the first virtual plane H1.

Here, it is preferable that the front end of the restricting portion 623 is positioned at the same position as the first virtual plane H1 in the front-rear direction, or positioned behind the first virtual plane H1. Therefore, the interference of the cable support 62 can be reduced. In addition, the cable support 62 is disposed in front of the withdrawing part 61, so that the power cable 4 can be more easily placed on the support part 622 (for example, wrapped around the support part 622), and ease of use can be improved.

(2) Modifications

The above embodiment is only one of the various embodiments of the present disclosure. The embodiments can be modified in various ways according to the design, etc., as long as the purpose of cost disclosure can be achieved. Hereinafter, modification examples will be described.

In the power supply device 1 according to the above embodiment, the direction in which the guide portion 57 guides the plug 3 is inclined with respect to the mounting surface 71, but in Modification 1, as shown in FIG. 8, the direction D2 is along the mounting surface. Surface 71. However, in this modification 1, the plug 3 is held by the holder 54 in a state where the plug 3 is rotated about the axis S3 along the protruding direction D1 of the above-mentioned embodiment. The first straight line S1 that is the direction in which the handle 32 extends is inclined with respect to the mounting surface 71. Assuming that the first straight line S1 passes through the first position P1 and the second position P2, the distance A2 between the mounting surface 71 and the second position P2 is longer than the distance A1 between the mounting surface 71 and the first position P1. In this embodiment, the first position P1 is located near the center of the end of the distal end 33 on the length axis of the handle 32. In this embodiment, the second position P2 is located at the center 321 of the rear end on the length axis of the handle 32.

According to this modification, the first straight line S1 is inclined with respect to the mounting surface 71. Therefore, when the plug 3 is held by the holder 54, the straight line S2 passing through the center 38 c of the distal end of the power terminal 38 and the center 321 of the rear end of the handle 32 is inclined with respect to the mounting surface 71. Therefore, according to this modification, even if the guiding portion 57 has a structure to guide the plug 3 to the holder 54 along the mounting surface 71, the gripping handle 32 can be reduced when the user places the plug 3 on the holder 54 The interference between the hand and the mounting surface 71.

In the present disclosure, “guided along the mounting surface 71” may not mean guiding in parallel to the mounting surface 71, but may mean guiding in a direction slightly inclined with respect to the mounting surface 71.

(2.2) Modification 2

The difference between the power supply device 1A and the power supply device 1 according to the above-mentioned embodiment is that the plug holder 5A is provided on the left side surface 282 of the housing 22 (which is the left side surface of the main body 2). The plug holder 5A includes an attachment part 51 and a holder 54, which have the same structure as the attachment part 51 and the holder 54 of the plug holder 5. That is, in the power supply device 1 according to the above embodiment, the plug holder 5 is attached to the right side surface 281 of the housing 22 (which is the right side surface of the body 2), but in the power supply device 1A according to this modification, the plug The holder 5A is attached to the plug holder 5 by using The attachment portion 51 and the holding device 54 having the same structure as the holding portion 51 and the holding device 54 are attached to the left side surface 282. In short, the plug holder (5, 5A) can be attached to a selected surface of one surface and the other surface (which is the opposite surface in one direction of the body 2). Therefore, for example, the same attachment portion 51 and the same holder 54 can be used for the plug holder 5 attached to the right side surface 281 and the plug holder 5A attached to the left side surface 282, thereby saving inventory control and manufacturing costs.

As shown in FIGS. 10 to 12, the plug holder 5A includes an attachment portion 51, a holder 54, and an adjustment member 59. The attachment part 51 and the holding tool 54 have the same structure as the attachment part 51 and the holding tool 54 of the above embodiment.

The first member 591 is fixed to the frame 52 by using the fastener F2. Specifically, the first member 591 includes a first flat plate portion 5911 and a pair of first side plate portions 5912. The first flat plate portion 5911 has a rectangular shape. The surface of the first flat portion 5911 facing the attachment portion 51 serves as the first surface 592. The pair of first side plate portions 5912 protrude from both ends toward the second member 593 (the side of the first flat plate portion 5911 opposite to the attachment portion 51) in the first direction orthogonal to the thickness axis of the first flat plate portion 5911. Each first side plate portion 5912 has a triangular shape. As each first side plate portion 5912 moves in a second direction orthogonal to the thickness axis of the first flat plate portion 5911 and the first direction The first end portion extends to the second end portion, and each first side plate portion 5912 protrudes from the first flat plate portion 5911 more and more. Each of the pair of first side plate portions 5912 includes a pair of through holes 5913, and the fastener 595 passes through the pair of through holes 5913, respectively. The first flat portion 5911 includes a pair of through holes 5914 and 5914 at both ends in the second direction, and the fastener F2 passes through the through holes. The first member 591 is attached to the attachment part 51 by using the fastener F2 and the through hole 5914.

The second member 593 has a second surface 594. The second surface 594 is a surface facing at least a part of the surface of the holder 54. The second surface 594 is a surface (outer surface) on the thickness axis of the second member 593. The second surface 594 is flat and faces the fixing plate 55 of the holder 54. The second member 593 is fixed to the holder 54 by using the fastener F1. Specifically, the second member 593 includes a second flat plate portion 5931 and a pair of second side plate portions 5932. The second flat plate portion 5931 has a rectangular shape. The surface of the second flat portion 5931 facing the holder 54 serves as the second surface 594. The pair of second side plate parts 5932 protrude from both ends toward the first member 591 (the side of the second flat plate part 5931 opposite to the holder 54) in the first direction orthogonal to the thickness axis of the second flat plate part 5931. Here, the size of the first flat plate portion 5911 and the second flat plate portion 5931 is set so that the pair of second side plate portions 5932 can be disposed between the pair of first side plate portions 5912. Each second side plate portion 5932 has a triangular shape. As each second side plate portion 5932 extends from the first end to the second end in the second direction orthogonal to the thickness axis of the second flat plate portion 5931 and the first direction, each second side plate portion 5932 extends from the first end to the second end.

The second flat portion 5931 includes a pair of screw holes 5934 and 5934 corresponding to the fastener F1 at both ends in the second direction, respectively. The holder 54 is attached to the second member 593 by using the fastener F1 and the screw hole 5934.

In this modification, the fasteners 595, F1, and F2 are screws. The fasteners F1 and F2 may not be limited to screws, but may be, for example, pins, rivets, and the like. However, the attachment of the adjustment member 59 and the attachment portion 51 The connection and the attachment of the holding tool 54 and the adjustment member 59 can not only be realized by such fasteners, but also can be realized by, for example, joining, welding, assembling, hooking structure, snap fit structure, etc. .

The first member 591 and the second member 593 are coupled to each other so that the second surface 594 is inclined with respect to the first surface 592. Specifically, the first member 591 and the second member 593 are arranged so that the first end and the second end of the first member 591 in the second direction respectively face the second member 593 in the second direction. One end portion and the second end portion, so that the pair of second side plate portions 5932 and 5932 are disposed between the pair of first side plate portions 5912 and 5912. The fastener 595 is coupled to the screw hole 5933 by passing the through hole 5913 to couple the first member 591 and the second member 593 to each other. Therefore, the adjustment member 59 shown in FIG. 13 is obtained.

In the adjustment member 59, the second surface 594 is inclined with respect to the first surface 592. The angle θ3 between the second surface 594 and the first surface 592 satisfies the relationship of, for example, 0°<θ3<90°. In particular, in this modification example, θ3 is equal to 2*θ2.

The adjusting member 59 (the first member 591 and the second member 593) is made of the same material as the frame 52. Therefore, the rigidity of the adjustment member 59 (the first member 591 and the second member 593) is higher than the rigidity of the housing 22. The strength of the adjustment member 59 (the first member 591 and the second member 593) is higher than the strength of the housing 22. The first member 591 and the second member 593 of the adjusting member 59 are respectively formed by bending a metal plate. Examples of the metal plate referred to here may include steel plate, stainless steel plate, and aluminum plate. However, the adjustment member 59 may be made of synthetic resin. The adjustment member 59 may not be formed of a plate-shaped material, but may be formed of, for example, a wedge-shaped rubber material, synthetic resin, or the like. The adjustment member 59 may be formed by joining the first flat portion 5911 and the second flat portion 5931 by welding.

(2.3) Other modifications

Other modifications of the embodiment are listed below.

In the above-described embodiment, the mounting surface 71 is larger than the body 2 in the front-rear direction. However, in the present disclosure, such as a dedicated mount or the like, the mounting surface 71 may have the same size as the body 2 in the front-rear direction. Even in this case, when the mounting surface 71 is set to a surface (vertical surface) along a vertical plane (such as a wall surface, a hedge surface, a surface separated by a fence or a fence, and a surface separated by a net or mesh ) When adjacent, it can be similar to the above embodiment to reduce the interference between the hand and the vertical surface. Therefore, the ease of use can be improved even in this modification.

However, the holding tool 54 can be realized by forming a recess in the top plate 231 having a shape corresponding to the outer shape of the plug 3. In this case, the plug 3 is carried on the holder 54. However, in this disclosure, "bearing" is also included in the meaning of "holding".

In the above embodiment, the plug 3 is held by being inserted into the holder 54 in one direction. However, in the present disclosure, the structure of the holder 54 to hold the plug 3 is not limited to the structure that realizes the insertion operation. For example, in addition to the above-mentioned bearing structure, a hooking structure or the like may also be used.

In the above-mentioned embodiment, the guiding part 57 is included in the holding tool 54, but in the present disclosure, the holding tool 54 and the guiding part 57 may be separate components.

The plug holders 5 and 5A according to the present disclosure may be directly attached to the side plate 233 of the housing 22 or may be attached to the side plate 233 of the housing 22 with another member in between.
