(1) Outline As shown in FIGS. 2 to 4, the wiring device apparatus 10 according to this embodiment includes a wiring device 1 and a wiring device cover 2 that covers the wiring device 1 (hereinafter also simply referred to as “cover”). And.

  In the present embodiment, the wiring device 1 has a function of an outlet that is connected to a plug of an electric device and supplies electric power to the electric device. Here, as an outlet, a two-port outlet for an AC 100V with a grounding electrode and capable of connecting two plugs at the same time is illustrated. Moreover, in this embodiment, the wiring instrument apparatus 10 for outdoor attached to the outer wall of a building is illustrated as the wiring instrument apparatus 10. FIG. The building where the wiring device 10 is installed is, for example, a detached house, an apartment house, an office, a store, a nursing facility, or the like. That is, in this embodiment, the wiring device apparatus 10 is an outdoor outlet device.

  The wiring device apparatus 10 is attached to a construction surface (outer wall surface of a building) in a state where an electric wire is electrically connected to the wiring device 1. In this wiring device apparatus 10, electric power can be supplied from the wiring device 1 to the electric device by connecting the plug 100 (see FIG. 9) of the electric device to the wiring device 1. Here, the wiring device apparatus 10 is in a state in which the connection surface 311 in which the insertion hole 312 (see FIG. 4) into which the plug blades 102A and 102B (see FIG. 9) of the plug 100 are inserted in the wiring device 1 is directed downward. And attached to the construction surface 900 (see FIG. 9). Therefore, the plug 100 is connected to the wiring device 1 from below, and rainwater does not easily enter the wiring device 1 from the insertion hole 312 and the ground insertion hole 313.

  The wiring device apparatus 10 configured as described above is installed, for example, in a garage or the like, and is used for charging an electric vehicle. That is, when the plug 100 of the charging cable connected to the electric vehicle is connected to the wiring device apparatus 10, the electric power can be supplied from the wiring device 1 to the electric vehicle via the charging cable. Is possible. Here, the “electric vehicle” is a vehicle that has a storage battery and travels using electric energy stored in the storage battery. The electric vehicle is, for example, an electric vehicle that travels by the output of the electric motor or a plug-in hybrid vehicle that travels by combining the output of the engine and the output of the electric motor. The electric vehicle may be a senior car, a two-wheeled vehicle (electric motorcycle), a tricycle, an electric bicycle, or the like. Furthermore, the use of the wiring device apparatus 10 is not limited to the charging of the electric vehicle, and the wiring device apparatus 10 may be used for supplying power to various electric devices such as a lighting device and an electric tool.

  However, the wiring device apparatus 10 according to the present embodiment is an outlet apparatus that does not have a lock mechanism that prevents the plug 100 from coming off. Therefore, the wiring device apparatus 10 is suitable for an application in which the plug 100 is frequently inserted and removed, such as an electric vehicle, rather than an electric device that is used with the plug 100 connected for a long period of time, such as a water heater. .

(2) Overall Configuration Hereinafter, the overall configuration of the wiring device apparatus 10 according to the present embodiment will be described in detail.

  In the present embodiment, a direction perpendicular (orthogonal) to the horizontal plane in a state where the wiring apparatus device 10 is attached to the outer wall surface of the building which is the construction surface 900 is defined as the “vertical direction”. The description will be made assuming that the lower side (vertical direction) as viewed from the front is “lower”. Further, a direction that is orthogonal to the vertical direction and that is parallel to the construction surface 900 will be referred to as a “left-right direction”, and the right side when viewing the wiring device device 10 from the front will be described as “right”, and the left side will be described as “left”. Furthermore, the direction orthogonal to both the up-down direction and the left-right direction, that is, the direction orthogonal to the construction surface 900 is referred to as “front-rear direction”, and the wiring device device 10 side as viewed from the construction surface 900 is described as “front”. The arrows indicating “vertical direction”, “left / right direction”, and “front / rear direction” in the drawings are merely shown for the purpose of explanation, and are not accompanied by an entity.

  However, these directions are not intended to limit the direction of use of the wiring device apparatus 10. For example, when the wiring device 10 is attached to the floor instead of the wall surface, the “front-rear direction” is a direction perpendicular to the horizontal plane, and the “up-down direction” and the “left-right direction” are directions parallel to the horizontal plane. . Further, even when the wiring fixture device 10 is attached to the wall surface, the “left-right direction” can be obtained by attaching the wiring fixture device 10 to the wall surface in a direction (that is, sideways) in which the “vertical direction” is parallel to the horizontal plane. The direction is perpendicular to the horizontal plane.

(2.1) Configuration of Wiring Device First, the configuration of the wiring device 1 will be described with reference to FIGS. The wiring device 1 includes an outlet 3, a body 4 that holds the outlet 3, and a waterproof plate 5 that is attached to the rear surface of the body 4.

  The outlet 3 includes a case 30 and built-in components such as blade receiving members 14A and 14B (see FIG. 7) housed in the case 30. The case 30 is configured by combining three members of an inner cover 31, a first case 32, and a second case 33. The case 30 is made of urea resin, for example. The first case 32 and the second case 33 are combined and integrated in the front-rear direction so that the rear surface of the first case 32 is covered with the second case 33. The first case 32 and the second case 33 are combined with each other to form a box-shaped inner body having an opening on the lower surface. The inner cover 31 is combined with the first case 32 and the second case 33 so as to close the opening on the lower surface of the inner body (the first case 32 and the second case 33). The lower surface of the inner cover 31 constitutes a connection surface 311. The connection surface 311 is formed with an insertion hole 312 and a ground insertion hole 313 into which the plug blades 102A and 102B of the plug 100 and the ground plug blade 102C (see FIG. 9) are inserted. The internal configuration of the outlet 3 will be described in detail in the section “(3) Details of outlet”.

  The outlet 3 has a terminal portion 180 (see FIG. 7) for connecting an electric wire. Here, the terminal portion 180 is a wire insertion type fast-connection terminal to which an electric wire is connected by inserting the electric wire from a terminal hole 34 formed on the rear surface of the case 30 (second case 33). In the present embodiment, a total of three electric wires including a pair of power supply lines and a ground line (earth line) are connected to the outlet 3. Furthermore, the terminal part 180 has a feed terminal for feed wiring, and a maximum of six wires can be connected. A release operation hole 341 for inserting a jig such as a driver is formed on the side of the terminal hole 34 on the rear surface of the case 30. By inserting a jig such as a driver from the release operation hole 341, the electric wire holding state in the terminal portion 180 is released.

  In addition, the outlet 3 has an extension terminal plate 35 that constitutes a screw-type terminal for connecting a ground wire of an electric device. The extension terminal plate 35 is made of a conductive metal plate and is formed in a strip shape that is long in the vertical direction. The upper end portion of the extension terminal plate 35 is electrically connected to the ground electrode of the terminal portion 180 in the outlet 3 by being inserted from the rear surface of the case 30 (second case 33). The lower end portion of the extension terminal plate 35 is fixed to the rear surface of the body 4 by a pair of holding screws 36.

  The body 4 includes a rectangular frame-like frame body 41 that is long in the vertical direction, and a storage portion 42 that protrudes forward from the front surface of the frame body 41. The body 4 is made of, for example, ASA (Acrylate Styrene Acrylonitrile) resin. A ground terminal hole 411 is formed at a position corresponding to the lower end portion of the extension terminal plate 35 at the lower end portion of the frame body 41. The terminal screw 37 is fastened to the extension terminal plate 35 from the front surface of the frame body 41 through the ground terminal hole 411, whereby the extension terminal plate 35 and the terminal screw 37 constitute a ground terminal. That is, the grounding wire of the electric device can be electrically connected to the extension terminal plate 35.

  The front surface of the storage portion 42 is not parallel to the front surface of the frame body 41 but is inclined obliquely upward. Thereby, the protrusion amount of the accommodating part 42 from the front surface of the frame 41 becomes so large that it approaches the lower end edge of the accommodating part 42 in an up-down direction. In the present embodiment, the front surface of the storage portion 42 is not a flat surface but a curved surface that is curved so as to protrude obliquely upward. The inside of the storage part 42 is a cavity. A first opening 421 is formed on the lower surface of the storage portion 42, and a second opening 422 is formed on the rear surface of the storage portion 42.

  The outlet 3 is stored in the internal space of the storage unit 42. A pair of attachment pieces 331 for allowing the fixing screw 81 to pass through protrude from both side surfaces of the second case 33 in the left-right direction. The outlet 3 is fixed to the body 4 by a fixing screw 81. In a state where the outlet 3 is fixed to the body 4, the lower surface (connection surface 311) of the outlet 3 is exposed from the first opening 421 of the storage portion 42. In other words, the body 4 holds the outlet 3 with the connection surface 311 of the outlet 3 exposed.

  In this embodiment, the outlet 3 is held by the body 4 in an inclined state with respect to the vertical direction so that the connection surface 311 exposed from the first opening 421 faces slightly forward from the lower side (directly below) in the vertical direction. Has been. Here, not only the connection surface 311 but also the rear surface of the first case 32 and the front surface of the second case 33 are inclined with respect to the vertical direction, and the outlet 3 is held by the body 4 with the entire case 30 inclined. ing. Thereby, the insertion direction of the plug blades 102A and 102B and the ground plug blade 102C of the plug 100 connected to the wiring device 1 is slightly inclined with respect to the vertical direction. That is, the plug 100 is connected to the connection surface 311 from the diagonally forward rather than from below (directly below) in the vertical direction.

  The waterproof plate 5 is disposed so as to be sandwiched between the rear surface of the body 4 and the construction surface 900 (wall surface), and prevents rainwater from entering from the second opening 422 on the rear surface of the body 4. The waterproof plate 5 is formed in a rectangular plate shape that is slightly smaller than the frame 41 of the body 4. The waterproof board 5 is made of, for example, a soft vinyl chloride resin. Grooves 51 are formed in the outer peripheral portion of the front surface of the waterproof plate 5 along substantially the entire periphery except the lower portion. By fitting a rib 412 formed on the rear surface of the frame body 41 into the groove 51, rainwater can be prevented from entering the space between the waterproof plate 5 and the body 4. Furthermore, a rib 52 is formed on the outer peripheral portion of the rear surface of the waterproof board 5 along substantially the entire circumference. The rib 52 prevents rainwater from entering the space between the waterproof plate 5 and the construction surface 900. In addition, a through hole 54 is formed in the waterproof plate 5 at a position corresponding to the second opening 422.

  Here, the frame body 41 is formed with a pair of mounting holes 413 through which mounting screws are passed. In the waterproof plate 5, a pair of attachment holes 53 for passing attachment screws is formed at positions corresponding to the pair of attachment holes 413. Further, a decorative plate 82 for covering the lower mounting hole 413 of the pair of mounting holes 413 is attached to the front surface of the frame body 41. The decorative plate 82 is detachably attached to the front surface of the body 4. A circumferential groove 414 for attaching the cover 2 is formed on the front surface of the frame body 41 along the outer peripheral edge of the storage portion 42.

  With the configuration described above, in the wiring device 1, the body 4 and the waterproof plate 5 are attached to the construction surface 900 with a pair of mounting screws in a state where the outlet 3, the body 4, and the waterproof plate 5 are combined. At this time, the electric wire drawn out from the construction surface 900 is introduced into the internal space of the storage portion 42 through the through hole 54 and the second opening 422 and connected to the terminal portion 180 of the outlet 3 in the storage portion 42. . After the wiring device 1 is attached to the construction surface 900, the decorative plate 82 is attached to the body 4 so that the lower mounting screw of the pair of mounting screws is covered by the decorative plate 82. Furthermore, by attaching the cover 2 to the wiring device 1, the upper mounting screw of the pair of mounting screws is covered by the cover 2.

(2.2) Configuration of Wiring Device Cover Next, the configuration of the cover 2 will be described with reference to FIGS. 5 and 6. The cover 2 includes a cover main body 6 and a label member 7.

  The cover body 6 is formed in a box shape so as to cover the wiring device 1. In the present embodiment, openings are formed in the rear surface and the lower surface of the cover body 6. Specifically, the cover main body 6 integrally includes a main wall portion 60, a first side wall 61, and a second side wall 62. The main wall portion 60 covers the wiring device 1 from at least one of the front and upper sides. The first side wall 61 is adjacent to the main wall portion 60 and covers the wiring device 1 from the left side. The second side wall 62 is adjacent to the main wall portion 60 and covers the wiring device 1 from the right side. In the present embodiment, the main wall portion 60 includes a front wall 601 that covers the wiring device 1 from the front, and an upper wall 602 that covers the wiring device 1 from above.

  Here, the cover body 6 is configured not to cover the entire wiring device 1 but to cover a part of the wiring device 1. In the present embodiment, the cover body 6 is formed in a shape that covers at least the storage portion 42 in which the outlet 3 is stored in the wiring device 1 from the front, upper, left side, and right side. In other words, even when the cover body 6 is attached to the wiring device 1, the rear surface of the wiring device 1 and the lower surface of the storage portion 42 are not covered by the cover body 6 and are exposed from the cover body 6. Become.

  More specifically, the cover body 6 has a rear surface and a lower surface that are open, and is formed in a hollow rectangular parallelepiped shape that is long in the vertical direction. In the present embodiment, the thicknesses of the front wall 601, the upper wall 602, the first side wall 61, and the second side wall 62 are substantially the same dimensions. The front wall 601 is formed in a rectangular plate shape that is orthogonal to the front-rear direction and is long in the up-down direction. The upper wall 602 is configured to protrude rearward from the upper end edge of the front wall 601. The upper wall 602 is formed in a rectangular plate shape that is long in the left-right direction. The first side wall 61 is configured to protrude rearward from the left end edge of the front wall 601. The second side wall 62 is configured to protrude rearward from the right edge of the front wall 601. The left end edge of the upper wall 602 is connected to the upper end edge of the first side wall 61, and the right end edge of the upper wall 602 is connected to the upper end edge of the second side wall 62.

  In the present embodiment, both the connecting portion between the front wall 601 and the first side wall 61 and the connecting portion between the front wall 601 and the second side wall 62 are curved with a first radius of curvature. Further, the connecting portion between the front wall 601 and the upper wall 602, the connecting portion between the upper wall 602 and the first side wall 61, and the connecting portion between the upper wall 602 and the second side wall 62 are all the first. Curved with a radius of curvature of 2. The first radius of curvature is greater than the second radius of curvature.

  Here, each of the first side wall 61 and the second side wall 62 is substantially orthogonal to the front wall 601. That is, each of the first side wall 61 and the second side wall 62 is substantially orthogonal to the left-right direction. However, “orthogonal” used in the present disclosure is meant to include not only a state of intersecting strictly at 90 degrees but also a state of approximately orthogonal within a certain error range. On the other hand, the upper wall 602 is not parallel to the horizontal plane, but is slightly inclined toward the front side. That is, the upper wall 602 is slightly lowered forward, and a slope is provided on the upper surface of the cover body 6 so that rainwater does not collect.

  Further, the rear end portion of each of the first side wall 61 and the second side wall 62 is formed in a shape extending downward from the lower end edge of the storage portion 42. As a result, the vertical dimension of the cover body 6 is substantially the same as the vertical dimension of the body 4, and one of the body 4 and the cover body 6 when the wiring device device 10 is viewed from the lateral side. The experience is enhanced.

  Incidentally, the cover body 6 is made of a flame retardant resin containing a luster pigment. The “brilliant pigment” as used herein is a pigment that is made of, for example, metal powder (metal flakes), mica, titanium oxide, glass flakes, and the like and exhibits a metallic luster or pearly luster. In this embodiment, metal powder (aluminum flakes as an example) is used as the luster pigment, and the flame-retardant resin constituting the cover body 6 is colored in a metallic color. That is, the flame retardant resin constituting the cover body 6 is a so-called original (raw material coloring) resin that is colored at the raw material stage before molding by containing a bright pigment in a base material made of a translucent resin. is there. By using this kind of original resin, it is possible to achieve coloring such as a metallic color on the finished product (cover body 6) even without painting (painting-less). The base material of the flame retardant resin is, for example, polycarbonate.

  The term “flame retardant resin” as used herein refers to a resin that is not flammable but flammable when the resin flammability is classified into flammable and flame retardant (including non-flammable). is there. In the present embodiment, the cover main body 6 has a flame retardance of not less than flame retardant UL94 V-2. “UL94” is a standard for evaluation of flame retardancy established by UL (Underwriters Laboratories). UL94 standard grades include “HB” in horizontal combustion test, “V-2”, “V-1”, “V-0”, “5VA”, “5VB” in vertical combustion test. There is a grade. These six grades have the lowest flame retardancy of “HB”, in the order of “HB”, “V-2”, “V-1”, “V-0”, “5VB”, “5VA” Increases nature. That is, the cover body 6 having flame retardancy equal to or higher than UL94 V-2 is “V-2”, “V-1”, “V-0”, “5VB” and “5VA” except for “HB”. It will have any flame retardancy. A resin having flame retardancy of UL94 V-2 or higher has a property (self-extinguishing property) that burns in the atmosphere while being exposed to a flame but extinguishes when separated from the flame. In other words, the flame retardant resin used as the material of the cover body 6 preferably has a flame retardancy of “V-2” or higher in the UL94 standard when the thickness of the sample is, for example, 2.5 mm.

  Here, an affixing portion 604 for affixing the label member 7 is formed at the center in the left-right direction on the front surface 603 of the front wall 601. The affixing portion 604 is slightly recessed as compared to the left and right ends of the front surface 603 of the front wall 601. The affixing portion 604 is formed over substantially the entire length of the front wall 601 in the vertical direction. A gate mark 66 is located substantially at the center of the pasting portion 604. In other words, the gate mark 66 is provided on one surface (front surface 603) of the main wall 60 on the front wall 601 opposite to the wiring device 1. The gate mark 66 is a portion that becomes an entrance of the resin when the resin flows into the mold when the cover body 6 is molded.

  In addition, at least one surface of the cover main body 6 on the side opposite to the wiring device 1 in each of the first side wall 61 and the second side wall 62 is an uneven surface that is embossed. The “texture processing” referred to here is a process of applying a fine wrinkle pattern (texture) on the surface of the cover body 6 when the cover body 6 is formed. In the present embodiment, in the cover main body 6, the left side surface of the first side wall 61 (one surface on the side opposite to the wiring device 1) is composed of the uneven surface 611, and the second side wall 62 (on the side opposite to the wiring device 1). 1 surface) is formed of the uneven surface 621. Further, the front surface 603 of the front wall 601 and the upper surface of the upper wall 602 of the cover main body 6 are also formed of uneven surfaces that are similarly textured. Thereby, even if the cover main body 6 is unpainted (paint-less), it is possible to realize a texture similar to painting due to fine irregularities on the surface. However, since the sticking portion 604 of the front surface 603 of the front wall 601 is covered with the label member 7, it does not have to be an uneven surface.

  Moreover, the cover main body 6 has the 1st rib 63, the 2nd rib 64, and the hooking claw 65 as a structure for a coupling | bonding with the wiring appliance 1, as shown in FIG. The first rib 63 protrudes from the inner surface of the rear end portion of each of the first side wall 61 and the second side wall 62. The second rib 64 protrudes from the inner surface of the rear end portion of the upper wall 602. Each of the first rib 63 and the second rib 64 is formed in a shape extending along the peripheral edge of the opening on the rear surface of the cover body 6. The hooking claw 65 protrudes from the rear surface of the lower end portion of the front wall 601.

  The label member 7 has a thin plate shape and is attached to the attaching portion 604 of the cover body 6. That is, the label member 7 is attached to one surface (front surface 603) of the front wall 601 of the main wall portion 60 so as to cover the gate mark 66. The label member 7 may be affixed to the affixing part 604 with an adhesive or an adhesive tape, or may be affixed to the affixing part 604 with an adhesive or the like. The material of the label member 7 is resin, metal, paper, or the like.

  With the above-described configuration, the cover 2 can be attached to and detached from the wiring device 1 while the wiring device 1 remains attached to the construction surface 900. Here, the cover 2 is attached to the wiring device 1 by being slid downward while being pressed against the body 4 from the front. At this time, the first rib 63 and the second rib 64 fit into the circumferential groove 414 formed in the body 4, and the hooking claw 65 is hooked on the front end portion of the lower surface of the storage portion 42, thereby The cover 2 is joined. On the other hand, the cover 2 is slid upward with a jig such as a screwdriver inserted into the gap between the rear surface of the front wall 601 and the front surface of the storage portion 42 to release the hooking claw 65, thereby 2 is removed from the wiring device 1. Therefore, in the wiring device apparatus 10, it is possible to replace only the cover 2 without removing the wiring device 1 from the construction surface 900.

(3) Details of Outlet (3.1) Basic Configuration Next, the configuration of the outlet 3 will be described in detail. The outlet 3 is an outlet to which the plug 100 of the electrical device is connected. As shown in FIG. 9, the plug 100 includes a plug body 101, a pair of plug blades 102A and 102B serving as power supply electrodes, and a ground plug blade 102C serving as a ground electrode. The plug blades 102A and 102B and the ground plug blade 102C are provided so as to protrude from one surface of the plug body 101. Each of the plug blades 102A and 102B has a flat plate shape, and the grounding plug blade 102C has a cylindrical shape (round pin shape) having a hemispherical tip. The plug blades 102A and 102B face each other. Here, the protruding amount of the ground plug blade 102C from the plug body 101 is set larger by a predetermined amount L0 than the protruding amount of the plug blades 102A and 102B from the plug body 101.

  The following description will be made using “first direction Z”, “second direction Y”, and “third direction X” with reference to the insertion direction of the plug 100. The first direction Z is the insertion direction of the plug 100.

  The grounding member 14C has a first grounding piece 141C and a second grounding piece 142C that face each other in the third direction X. The ground member 14C is configured to be electrically connected to the ground plug blade 102C in a state where the ground plug blade 102C is sandwiched between the first ground piece 141C and the second ground piece 142C.

  The first ground piece 141C and the second ground piece 142C are arranged side by side in the third direction X so that the first ground piece 141C is opposite to the blade receiving members 14A and 14B. The grounding member 14C further includes a connecting piece 143C (see FIG. 1A) that connects the first grounding piece 141C and the second grounding piece 142C. The connecting piece 143C connects the ends of the first grounding piece 141C and the second grounding piece 142C opposite to the ground insertion hole 313 in the first direction Z.

  The first grounding piece 141 </ b> C includes a base 121, an inclined portion 122, and a guide portion 124. The second grounding piece 142C includes a base 131, an inclined portion 132, an intermediate portion 133, and a guide portion 134. Base portions 121 and 131 of the first ground piece 141C and the second ground piece 142C are connected by a connecting piece 143A. The first ground piece 141C and the second ground piece 142C are asymmetric in the third direction X.

  The bases 121 and 131 are opposed to each other and are disposed substantially parallel to the first direction Z. The inclined portions 122 and 132 protrude from the edge on the ground insertion hole 313 side of the base portions 121 and 131 toward the ground insertion hole 313. The inclined portions 122 and 132 are inclined with respect to the first direction Z so as to approach each other as the ground insertion hole 313 is approached. The intermediate portion 133 protrudes from the edge of the inclined portion 132 on the ground insertion hole 313 side toward the ground insertion hole 313. The intermediate part 133 is inclined with respect to the first direction Z so as to approach the first grounding piece 141C as it approaches the grounding insertion hole 313. The inclination angle of the intermediate part 133 with respect to the first direction Z is smaller than the inclination angle of the inclination part 132 with respect to the first direction Z. The guide part 124 protrudes from the edge on the ground insertion hole 313 side in the inclined part 122 toward the ground insertion hole 313. The guide part 134 protrudes toward the ground insertion hole 313 from the end edge of the intermediate part 133 on the ground insertion hole 313 side. The guide parts 124 and 134 are inclined with respect to the first direction Z so as to be separated from each other as they approach the ground insertion hole 313. The inclination angle of the guide part 124 with respect to the first direction Z is smaller than the inclination angle of the guide part 134 with respect to the first direction Z and larger than the inclination angle of the intermediate part 133 with respect to the first direction Z.

  Here, the dimensions of the first ground piece 141C and the second ground piece 142C in the first direction Z are set to be approximately equal. Specifically, in the first direction Z, the total size of the base 121 and the inclined portion 122 in the first ground piece 141C and the total size of the base 131 and the inclined portion 132 in the second ground piece 142C are substantially equal. In the first direction Z, the size of the guide portion 124 in the first ground piece 141C and the total size of the intermediate portion 133 and the guide portion 134 in the second ground piece 142C are substantially equal.

  According to this configuration, the distance between the first ground piece 141 </ b> C and the second ground piece 142 </ b> C in the third direction X is the connection between the inclined portion 122 and the guide portion 124, and the connection between the inclined portion 132 and the intermediate portion 133. It becomes the minimum in the ground electrode holding part 125 which consists of a part. That is, in the corner portion 136 formed by the connection portion between the intermediate portion 133 and the guide portion 134, the distance between the first ground piece 141C and the second ground piece 142C in the third direction X is not minimum. The distance between the first ground piece 141 </ b> C and the second ground piece 142 </ b> C in the ground electrode holding portion 125 is set to be smaller than the diameter of the ground plug blade 102 </ b> C. On the other hand, the distance between the first ground piece 141C and the second ground piece 142C at the edge on the ground insertion hole 313 side in the guide portions 124 and 134 is set to be larger than the diameter of the ground plug blade 102C.

  Next, the relative positional relationship between the blade receiving members 14A and 14B and the grounding member 14C will be described with reference to FIG. FIG. 10 is a cross-sectional view showing a part of the outlet 3, in which the periphery of the blade receiving member 14B is viewed from one side in the third direction X, and the periphery of the ground member 14C is in the second direction Y The cross section seen from one side is shown. Here, the relationship between the blade receiving member 14B and the grounding member 14C is illustrated, but the relationship between the blade receiving member 14A and the grounding member 14C is the same.

  Here, as a premise, the grounding plug blade 102C has a larger insertion amount from the connection surface 311 by a predetermined amount L0 than the plug blades 102A and 102B. That is, as described above, the protruding amount of the ground plug blade 102C from the plug body 101 is larger by the predetermined amount L0 than the protruding amount of the plug blades 102A and 102B from the plug body 101. Therefore, the amount of insertion from the connection surface 311 also has a difference of a predetermined amount L0 between the ground plug blade 102C and the plug blades 102A and 102B.

  The blade receiving member 14B is configured such that the plug blade 102B is sandwiched between the first blade receiving piece 141B and the second blade receiving piece 142B by the power supply electrode holding portion 115 located at the first distance L1 from the connection surface 311 in the first direction Z. Has been. Specifically, the power supply electrode holding portion 115 formed by the connection portion between the intermediate portion 113 and the guide portion 114 is located at a first distance L1 from the connection surface 311 in the first direction Z.

  The grounding member 14C is configured so that the grounding plug blade 102C is sandwiched between the first grounding piece 141C and the second grounding piece 142C at the grounding pole holding part 125 at the second distance L2 from the connection surface 311 in the first direction Z. ing. Specifically, the ground electrode holding portion 125, which includes the connecting portion between the inclined portion 122 and the guide portion 124, and the connecting portion between the inclined portion 132 and the intermediate portion 133, has a second distance from the connecting surface 311 in the first direction Z. It is in the position of L2.

  Here, with respect to the first distance L1 and the second distance L2, the following relationship is used by using a predetermined amount L0 which is a difference in insertion amount from the connection surface 311 between the ground plug blade 102C and the plug blades 102A and 102B. It is represented by That is, the second distance L2 is larger than a value (L1 + L0) obtained by adding a predetermined amount L0 to the first distance L1. That is, the predetermined amount L0, the first distance L1, and the second distance L2 have a relationship of “L2> L1 + L0”.

  In the first direction Z, the distance from the first ground piece 141C and the second ground piece 142C to the connection surface 311 is defined as a third distance L3. Similarly, in the first direction Z, a distance from the first blade receiving piece 141A and the second blade receiving piece 142A to the connection surface 311 is defined as a fourth distance L4. Then, with respect to the third distance L3 and the fourth distance L4, a predetermined amount L0 that is a difference in insertion amount from the connection surface 311 between the ground plug blade 102C and the plug blades 102A and 102B is used in the following relationship. expressed. That is, the third distance L3 is less than the value obtained by adding the predetermined amount L0 to the fourth distance L4 (L4 + L0) in both the first ground piece 141C and the second ground piece 142C. That is, the predetermined amount L0, the third distance L3, and the fourth distance L4 have a relationship of “L3 <L4 + L0”.

  Furthermore, in the present embodiment, the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 have a relationship of “L4 <L3 <L1 <L2”.

  The operation of connecting the plug 100 to the outlet 3 configured as described above will be described with reference to FIGS. 11A to 11C. 11A to 11C are schematic cross-sectional views showing a part of the outlet 3 as in FIG. 10, and illustrate the relationship between the blade receiving member 14B and the grounding member 14C.

  When the plug blade 102B and the ground plug blade 102C are inserted from the insertion hole 312 and the ground insertion hole 313, first, as shown in FIG. 11A, the ground plug blade 102C contacts the ground member 14C. In the state shown in FIG. 11A, the blade 102B is not in contact with the blade receiving member 14B. That is, since the third distance L3 is less than the value obtained by adding the predetermined amount L0 to the fourth distance L4 in both the first grounding piece 141C and the second grounding piece 142C, the plug blade 102B is connected to the blade receiving member 14B. Prior to contact, the ground plug blade 102C contacts the ground member 14C. At this time, even if the ground plug blade 102C is inclined with respect to the first direction Z due to the plug 100 being inserted at an angle, the ground plug blade 102C has the first ground piece 141C and the second ground piece. Any one of 142C contacts. However, in the state shown in FIG. 11A, since the grounding plug blade 102C has not reached the grounding electrode holding portion 125 of the grounding member 14C, neither the plug blade 102B nor the grounding plug blade 102C is held by the outlet 3. .

  When the plug blade 102B and the ground plug blade 102C are further inserted from the state shown in FIG. 11A, the plug blade 102B contacts the blade receiving member 14B, and then the plug blade 102B is connected to the blade receiving member 14B as shown in FIG. 11B. To the power supply electrode holding unit 115. Therefore, the plug blade 102B is sandwiched between the first blade receiving piece 141B and the second blade receiving piece 142B at the power supply electrode holding portion 115, and the blade receiving member 14B is connected to the plug blade 102B with a certain contact pressure. Electrically connected. However, in the state shown in FIG. 11B, the ground plug blade 102C does not reach the ground electrode holding portion 125 of the ground member 14C. That is, as described above, since the second distance L2 is larger than the value obtained by adding the predetermined amount L0 to the first distance L1, the plug blade 102B is reached before the ground plug blade 102C reaches the ground electrode holding portion 125. Reaches the power supply electrode holding unit 115.

  When the plug blade 102B and the ground plug blade 102C are further inserted from the state shown in FIG. 11B, the ground plug blade 102C reaches the ground electrode holding portion 125 of the ground member 14C as shown in FIG. 11C. Therefore, the grounding plug blade 102C is sandwiched between the first grounding piece 141C and the second grounding piece 142C at the grounding electrode holding part 125, and the grounding member 14C is electrically connected to the grounding plug blade 102C with a certain contact pressure. Connected. Here, from the state shown in FIG. 11B until the earthing plug blade 102C reaches the earthing pole holding part 125, the guide part 124 of the earthing member 14C is inclined with respect to the first direction Z. The force required to insert the plug 100 (insertion force) increases proportionally. Then, after the ground plug blade 102C reaches the ground electrode holding portion 125, the insertion force is reduced.

  As described above, in the outlet 3 according to the present embodiment, when the plug 100 is connected, first, the grounding plug blade 102C contacts the grounding member 14C. Thereafter, the plug blade 102B is sandwiched between the first blade receiving piece 141B and the second blade receiving piece 142B, and then the grounding plug blade 102C is sandwiched between the first grounding piece 141C and the second grounding piece 142C. .

  However, in the outlet 3, after the ground plug blade 102C contacts the ground member 14C, the plug blade 102B is sandwiched between the first blade receiving piece 141B and the second blade receiving piece 142B, and then the ground plug blade 102C is What is necessary is just the structure pinched | interposed between 1 C grounding piece 141C and 2nd grounding piece 142C. Therefore, it is not always necessary to set the distance from the power supply electrode holding portion 115, which is the connecting portion between the intermediate portion 113 and the guide portion 114, of the blade receiving member 14B to the connection surface 311 as the first distance L1. For example, when the blade receiving member 14B sandwiches the plug blade 102B at a position closer to the insertion hole 312 than the power pole holding portion 115, the distance from the connection surface 311 to this position is defined as the first distance L1, and “L2> The relationship of “L1 + L0” may be satisfied.

  Here, in the present embodiment, the connection surface 311 is a flat surface and does not have a structure for holding the plug body 101. That is, since the case 30 itself does not have a function of preventing the plug 100 from tilting, the plug 100 tends to tilt with respect to the first direction Z. Therefore, as described above, the grounding plug blade 102C comes into contact with either the first grounding piece 141C or the second grounding piece 142C, so that the grounding plug blade 102B comes into contact with the blade receiving member 14B before the grounding blade 102B comes into contact with the blade receiving member 14B. It is particularly useful for 102C to contact grounding member 14C.

(3.4) Door Block Next, the configuration of the door block 150 will be described in more detail with reference to FIGS. 12 and 13. The door body 15B is basically configured in common with the door body 15A and has a substantially symmetrical relationship in the second direction Y. Therefore, if “A” in the reference numerals is replaced with “B” in the description of the door body 15A, and the description of the orientation in the second direction Y is reversed, the door body 15B is described. The grounding door body 15C is basically the same configuration as the door body 15A. Therefore, in the following, among the door bodies 15A and 15B and the grounding door body 15C, the description of the same configuration as the door body 15A will be omitted as appropriate. Further, the elastic member 16B is basically in common with the elastic member 16A and has a substantially symmetrical relationship in the second direction Y. Therefore, if “A” in the reference numerals is replaced with “B” in the description of the elastic member 16A, and the description of the orientation in the second direction Y is reversed, the elastic member 16B is described. Further, the ground elastic member 16C is basically the same configuration as the elastic member 16A. Therefore, in the following, among the elastic members 16A and 16B and the ground elastic member 16C, the description of the same configuration as the elastic member 16A will be omitted as appropriate.

  The door body 15A is made of, for example, a synthetic resin. The door body 15A includes a plate-like support portion 151 extended along the first direction Z, and an opening / closing portion 152 protruding in the thickness direction of the support portion 151 from the end portion on the insertion hole 312 side of the support portion 151. Have. 15 A of door bodies are formed in the substantially L shape seeing from the 3rd direction X by the support part 151 and the opening-and-closing part 152. As shown in FIG. The support portion 151 is disposed on the opposite side of the first blade receiving piece 141A in the second direction Y from the second blade receiving piece 142A. The support portion 151 is configured to be rotatable about an end portion opposite to the insertion hole 312 as a fulcrum. The opening / closing part 152 is configured to be able to advance and retract with respect to the space between the insertion hole 312 and the blade receiving member 14 </ b> A as the support part 151 rotates. Accordingly, the door body 15A moves between a closed position that covers the blade receiving member 14A when viewed from the insertion hole 312 and an open position that exposes the blade receiving member 14A when viewed from the insertion hole 312.

  Further, the amount of protrusion of the opening / closing part 152 from the support part 151 is smaller as it approaches the insertion hole 312 in the first direction Z. As a result, the surface facing the insertion hole 312 forms an inclined surface 153 that is inclined with respect to the first direction Z. Further, the door body 15 </ b> A has a door stopper 154. The door stopper 154 is formed on the surface of the door body 15A opposite to the first blade receiving piece 141A in the second direction Y. The door stopper 154 is formed only on the door bodies 15A and 15B among the door bodies 15A and 15B and the ground door body 15C. The function of the door stopper 154 will be described in the column “(3.5) Abnormal opening prevention structure”.

  The elastic member 16A is made of, for example, a metal leaf spring. The elastic member 16A is disposed on the opposite side to the first blade receiving piece 141A in the second direction Y with respect to the support portion 151 of the door body 15A. The elastic member 16 </ b> A is fixed to the inner surface of the case 30. The elastic member 16A applies an elastic force to the door body 15A so as to push the support portion 151 toward the first blade receiving piece 141A.

  According to the above-described configuration, the door body 15A is positioned at the closed position by the elastic force of the elastic member 16A in a state where the plug blade 102A is not inserted into the insertion hole 312. Therefore, the insertion hole 312 is closed from the inside of the case 30 by the opening / closing part 152 of the door body 15A. In this state, when the plug blade 102A is inserted from the insertion hole 312, the tip of the plug blade 102A comes into contact with the inclined surface 153. When the plug blade 102A is further inserted from this state, the inclined surface 153 is pushed by the plug blade 102A, and the opening / closing part 152 is pushed out from the space between the insertion hole 312 and the blade receiving member 14A. The support portion 151 rotates while elastically deforming the elastic member 16A. Accordingly, the door body 15A moves from the closed position to the open position. On the other hand, when the plug blade 102A is removed, the door body 15A moves from the open position to the closed position by the elastic force of the elastic member 16A.

(3.5) Abnormal Opening Prevention Structure Next, a structure for preventing the “abnormal opening” of the blade receiving members 14A and 14B and the grounding member 14C will be described with reference to FIGS. 1A and 1B. FIG. 1A is a schematic perspective view showing a main part of the outlet 3 and omitting illustrations other than the inner cover 31, the first case 32, and the blade receiving block 140. FIG. 1B is a schematic perspective view showing the main part of the outlet 3 and omitting illustrations other than the inner cover 31 and the blade receiving block 140. The “abnormal opening” here means that the blade receiving members 14A and 14B and the grounding member 14C open beyond the movable range in the normal use of the wiring device apparatus 10. For example, in the state where the plug 100 is connected to the outlet 3, when a large external force is applied to the plug 100 in a direction crossing the first direction Z, the blade receiving members 14A, A large external force acts on 14B or the grounding member 14C. Specifically, when the plug 100 is pulled out with the power cord, so-called “unplugging”, or when a person's foot is caught on the power cord, the above-mentioned external force acts and “abnormally opens”. May occur. In particular, when the connection surface 311 is a flat surface and does not have a structure for holding the plug body 101 as in the present embodiment, the plug 100 tends to be inclined with respect to the first direction Z, so that “abnormal opening” is likely to occur. When the blade receiving members 14A and 14B and the grounding member 14C are “abnormally opened”, the blade receiving members 14A and 14B and the grounding member 14C may be plastically deformed, thereby hindering the function as an outlet. is there. In the present embodiment, the configuration described below is adopted as a countermeasure against such “abnormal opening”.

  That is, the blade receiving member 14A has a pair of stoppers 116 protruding from both end edges of the first blade receiving piece 141A in the third direction X, as shown in FIG. 1A. The pair of stoppers 116 are formed so as to protrude from the guide portion 114 of the first blade receiving piece 141A to both sides in the third direction X. The pair of stoppers 116 are set to dimensions that protrude at least from both edges in the third direction X of the door body 15A to both sides in the third direction X. The inner cover 31 of the case 30 is formed with a pair of restricting portions 314 that face the pair of stoppers 116 in the second direction Y. The pair of restricting portions 314 are opposed to the pair of stoppers 116 from the side opposite to the second blade receiving piece 142 </ b> A in the second direction Y. The pair of restriction portions 314 are disposed on both sides of the insertion hole 312 in the third direction X in the inner cover 31.

  Accordingly, the movable range of the first blade receiving piece 141A in the direction away from the second blade receiving piece 142A in the second direction Y is limited by the pair of stoppers 116 coming into contact with the pair of restricting portions 314. In other words, the movable range of the first blade receiving piece 141A in a direction away from the second blade receiving piece 142A in the second direction Y is defined by the clearance between the pair of stoppers 116 and the pair of regulating portions 314.

  Here, the pair of stoppers 116 is provided only on the first blade receiving piece 141A adjacent to the door body 15A in the second direction Y among the first blade receiving piece 141A and the second blade receiving piece 142A. That is, with respect to the second blade receiving piece 142A, the regulating wall 318 provided on the inner cover 31 of the case 30 faces from the opposite side to the first blade receiving piece 141A in the second direction Y. Therefore, even if there is no stopper for the second blade receiving piece 142A, the movable range in the direction away from the first blade receiving piece 141A is limited by contacting the restriction wall 318. On the other hand, with respect to the first blade receiving piece 141A, the door 15A, which is a movable member, is located on the opposite side of the second blade receiving piece 142A in the second direction Y, and therefore no restriction wall can be provided. . Therefore, with respect to the first blade receiving piece 141A, by providing a pair of stoppers 116 protruding from both end edges in the third direction X, the movable range in the direction away from the second blade receiving piece 142A is limited.

  Here, the inner cover 31 is formed with a protrusion 316 positioned between the one restricting portion 314 and the second blade receiving piece 142A. The protruding portion 316 is disposed between the one stopper 116 and the second blade receiving piece 142A, and in a state where the plug 100 is not connected to the outlet 3, the first blade receiving piece 141A and the second blade receiving piece. Preliminary opening is performed to form a predetermined gap with 142A. Since the preliminary opening is performed, the force required to insert the plug blade 102A into the blade receiving member 14A is smaller than when the preliminary opening is not performed. Similar pre-opening protrusions 316 are also provided for the blade receiving member 14B (see FIG. 1B).

  In the present embodiment, the configuration for preventing “abnormal opening” is applied to the door body 15A. That is, a door stopper 154 is formed on the surface of the door body 15A opposite to the first blade receiving piece 141A in the second direction Y, as shown in FIG. The door stopper 154 is formed so as to protrude from the surface of the support portion 151 opposite to the first blade receiving piece 141A. The inner cover 31 of the case 30 is formed with a door restricting portion 315 that faces the door stopper 154 in the second direction Y. The door restricting portion 315 faces the door stopper 154 from the side opposite to the first blade receiving piece 141A in the second direction Y.

  Accordingly, the movable range of the door body 15A in the direction away from the first blade receiving piece 141A in the second direction Y is limited by the door stopper 154 coming into contact with the door restricting portion 315. In other words, the movable range of the door body 15A in the direction away from the first blade receiving piece 141A in the second direction Y is defined by the clearance between the door stopper 154 and the door restricting portion 315.

  Incidentally, the outlet 3 includes a blade receiving member 14B which is a “second blade receiving member” separately from the blade receiving member 14A which is a “first blade receiving member”. However, the pair of stoppers 116 is provided only on the blade receiving member 14A of the blade receiving members 14A and 14B. The reason why the stopper is not provided in the blade receiving member 14B is as follows.

  That is, the outlet 3 is provided with a guide wall 317 as a means for preventing the plug 100 from tilting in the third direction X in a state where the plug 100 is connected. Specifically, as shown in FIG. 1B, the case 30 has a guide wall 317 for preventing the inclination of the plug blade 102B in the third direction X on at least one side of the blade receiving member 14B in the third direction X. have. In the present embodiment, a pair of guide walls 317 are provided on both sides of the blade receiving member 14 </ b> B in the third direction X in the inner cover 31. Thereby, the inclination in the third direction X of the plug blade 102B inserted from the insertion hole 312 is suppressed by the pair of guide walls 317. Since it is effective to arrange such a guide wall 317 at a position close to the blade receiving member 14B in the third direction X, if the stopper is provided on the blade receiving member 14B, the stopper interferes with the guide wall 317. It will be. Therefore, in the present embodiment, the pair of stoppers 116 is provided only on the blade receiving member 14A among the blade receiving members 14A and 14B.

  Moreover, in the wiring device apparatus 10 which concerns on this embodiment, the case 30 is comprised so that the 2nd direction Y may be attached to the construction surface 900 in the direction which cross | intersects with the construction surface 900. FIG. The blade receiving members 14A and 14B are arranged side by side in the second direction Y so that the blade receiving member 14A is on the construction surface 900 side. Furthermore, the first blade receiving piece 141A and the second blade receiving piece 142A are arranged side by side in the second direction Y so that the first blade receiving piece 141A is on the construction surface 900 side. Therefore, when a so-called “zipper removal” or a person's foot is caught on the power cord, the first blade receiving piece 141A in the blade receiving member 14A closer to the construction surface 900 of the blade receiving members 14A and 14B. A large external force acts on the. That is, in such a case, since the external force hardly acts on the first blade receiving piece 141B of the blade receiving member 14B far from the construction surface 900, the "abnormal opening" by the pair of stoppers 116 is prevented. Only the receiving member 14A is sufficient.

  On the other hand, the structure for preventing “abnormal opening” is applied to the door body 15B as in the door body 15A. That is, a door stopper 154 is formed on the surface of the door body 15B opposite to the first blade receiving piece 141B in the second direction Y. The door 15 </ b> B has a movable range in a direction away from the first blade receiving piece 141 </ b> B in the second direction Y when the door stopper 154 comes into contact with the door restricting portion 315. As a result, although the first blade receiving piece 141B itself of the blade receiving member 14B has no structure for preventing “abnormal opening”, the door body 15B has the first blade receiving piece 142B in a direction away from the second blade receiving piece 142B to some extent. The movable range of the one-blade receiving piece 141B is limited.

  Further, the configuration for preventing “abnormal opening” is applied to the grounding member 14C as well as the blade receiving member 14A. That is, as shown in FIG. 1A, the grounding member 14C has a pair of grounding stoppers 126 protruding from both end edges of the first grounding piece 141C in the second direction Y. The pair of ground stoppers 126 are formed so as to protrude from the guide portion 124 of the first ground piece 141C to both sides in the second direction Y. The pair of grounding stoppers 126 are set to dimensions that protrude at least from both edges in the second direction Y in the grounding door body 15C to both sides in the second direction Y. The case 30 is formed with a pair of grounding restriction portions 310 and 321 that face the pair of grounding stoppers 126 in the third direction X. The pair of grounding restriction portions 310 and 321 face the pair of grounding stoppers 126 from the opposite side to the second grounding piece 142C in the third direction X. The grounding restriction part 310 is composed of a part of the inner cover 31, and the grounding restriction part 321 is composed of a part of the first case 32.

  Accordingly, the movable range of the first ground piece 141C in the third direction X in the direction away from the second ground piece 142C is limited by the pair of ground stoppers 126 coming into contact with the pair of ground regulating portions 310 and 321. . In other words, the movable range of the first ground piece 141 </ b> C in the third direction X in the direction away from the second ground piece 142 </ b> C is defined by the clearance between the pair of ground stoppers 126 and the pair of ground regulating portions 310 and 321. .

  Here, the pair of grounding stoppers 126 is provided only on the first grounding piece 141C adjacent to the grounding door body 15C in the third direction X among the first grounding piece 141C and the second grounding piece 142C. That is, with respect to the second grounding piece 142C, the regulation wall 319 provided on the inner cover 31 of the case 30 faces from the opposite side to the first grounding piece 141C in the third direction X. Therefore, for the second grounding piece 142C, even if there is no stopper, the movable range in the direction away from the first grounding piece 141C is limited by contacting the restriction wall 319.

(4) Advantages As described above, the outlet 3 according to the present embodiment includes the case 30, the blade receiving member 14A, and the door body 15A. An insertion hole 312 is formed in the case 30. The blade receiving member 14A is housed in the case 30 and is electrically connected to the plug blade 102A inserted from the insertion hole 312 along the first direction Z. The door body 15A is housed in the case 30 and moves between a closed position that covers the blade receiving member 14A when viewed from the insertion hole 312 and an open position that exposes the blade receiving member 14A when viewed from the insertion hole 312. To do. The blade receiving member 14A includes a first blade receiving piece 141A and a second blade receiving piece 142A that are opposed to each other in a second direction Y orthogonal to the first direction Z. The blade receiving member 14A is configured to be electrically connected to the plug blade 102A with the plug blade 102A sandwiched between the first blade receiving piece 141A and the second blade receiving piece 142A. 15 A of door bodies are arrange | positioned with respect to the 1st blade receiving piece 141A on the opposite side to the 2nd blade receiving piece 142A in the 2nd direction Y, and between a closed position and an open position along the 2nd direction Y Is configured to move. The blade receiving member 14A further includes a pair of stoppers 116 protruding from both end edges of the first blade receiving piece 141A in the third direction X orthogonal to both the first direction Z and the second direction Y. The case 30 is formed with a pair of restricting portions 314 that face the pair of stoppers 116 in the second direction Y. 141 A of 1st blade receiving pieces are comprised so that the movable range of the direction away from the 2nd blade receiving piece 142A in the 2nd direction Y may be restrict | limited by a pair of stopper 116 contacting a pair of control part 314. Yes.

  According to this configuration, the movable range of the first blade receiving piece 141A in the direction away from the second blade receiving piece 142A in the second direction Y is limited by the pair of stoppers 116 coming into contact with the pair of restricting portions 314. . Therefore, in the state where the plug 100 is connected to the outlet 3, even if a large external force is applied to the plug 100 in the direction intersecting the first direction Z, the “abnormal opening” is unlikely to occur in the blade receiving member 14A. Therefore, there is an advantage that the reliability of the outlet 3 is not easily lowered. Moreover, since the door body 15A is provided, intrusion of foreign matter from the insertion hole 312 into the case 30 is prevented in a state where the plug 100 is not connected, and this also suppresses a decrease in the reliability of the outlet 3. It is done. Here, since the pair of stoppers 116 protrude from both end edges in the third direction X of the first blade receiving piece 141A, it is possible to prevent “abnormal opening” without interfering with the door body 15A.

  Moreover, it is preferable that the door stopper 154 is formed in the surface on the opposite side to 141 A of 1st blade receiving pieces in the 2nd direction Y among the door bodies 15A like this embodiment. In this case, the case 30 is preferably formed with a door restricting portion 315 facing the door stopper 154 in the second direction Y. In this case, the door body 15A is configured such that the movable range in the direction away from the first blade receiving piece 141A in the second direction Y is limited by the door stopper 154 coming into contact with the door restricting portion 315. Is preferred. According to this configuration, since “abnormal opening” is prevented even in the door body 15A, “abnormal opening” in the blade receiving member 14A is more than in the case where “abnormal opening” is prevented only by the blade receiving member 14A. Hard to occur. Therefore, there is an advantage that the reliability of the outlet 3 is less likely to be lowered. However, this configuration is not essential for the outlet 3, and the door stopper 154 and the door restricting portion 315 may be omitted as appropriate.

  In addition, as in the present embodiment, the outlet 3 is arranged side by side in the second direction Y with the “first blade receiving member” that is the blade receiving member 14A, and is the “first plug blade” that is the plug blade 102A. It is preferable to further include a second blade receiving member 14B that is electrically connected to another second plug blade 102B. In this case, the pair of stoppers 116 are preferably provided only on the blade receiving member 14A of the blade receiving member 14A and the blade receiving member 14B. In this case, the case 30 preferably has a guide wall 317 for preventing the plug blade 102B from tilting in the third direction X on at least one side of the blade receiving member 14B in the third direction X. According to this configuration, the inclination of the plug blade 102B in the third direction X can be prevented by the guide wall 317 provided on at least one side of the blade receiving member 14B. However, this configuration is not essential for the outlet 3, and the pair of stoppers 116 may be provided on both the blade receiving member 14A and the blade receiving member 14B.

  Further, as in the present embodiment, the case 30 is preferably configured to be attached to the construction surface 900 in a direction in which the second direction Y intersects the construction surface 900. In this case, the blade receiving member 14A and the blade receiving member 14B are preferably arranged side by side in the second direction Y so that the blade receiving member 14A is on the construction surface 900 side. In this case, it is preferable that the first blade receiving piece 141A and the second blade receiving piece 142A are arranged side by side in the second direction Y so that the first blade receiving piece 141A is on the construction surface 900 side. According to this configuration, when a so-called “wrinkle removal” or a person's foot is caught on the power cord, of the blade receiving members 14A and 14B, the first one in the blade receiving member 14A closer to the construction surface 900. A large external force acts on the blade receiving piece 141A. That is, in such a case, since the external force hardly acts on the first blade receiving piece 141B of the blade receiving member 14B far from the construction surface 900, the "abnormal opening" by the pair of stoppers 116 is prevented. Only the receiving member 14A is sufficient. However, this configuration is not essential for the outlet 3, and the blade receiving member 14A and the blade receiving member 14B may be arranged side by side in the second direction Y so that the blade receiving member 14B is on the construction surface 900 side. Good.

  Further, as in the present embodiment, the outlet 3 preferably further includes a grounding member 14C and a grounding door body 15C. The ground member 14 </ b> C is housed in the case 30 and is electrically connected to the ground plug blade 102 </ b> C inserted along the first direction Z from the ground insertion hole 313 formed in the case 30. The ground door 15 </ b> C is housed in the case 30, and is between a closed position that covers the ground member 14 </ b> C when viewed from the ground insertion hole 313 and an open position that exposes the ground member 14 </ b> C when viewed from the ground insertion hole 313. Moving. The grounding member 14C has a first grounding piece 141C and a second grounding piece 142C that face each other in the third direction X, and the grounding plug blade 102C is sandwiched between the first grounding piece 141C and the second grounding piece 142C. In this state, it is configured to be electrically connected to the ground plug blade 102C. The ground door 15C is disposed on the opposite side of the first ground piece 141C in the third direction X from the second ground piece 142C, and moves between the closed position and the open position along the third direction X. Is configured to do. In this case, it is preferable that the grounding member 14 </ b> C further includes a pair of grounding stoppers 126 that protrude from both end edges of the first grounding piece 141 </ b> C in the second direction Y. In this case, the case 30 is preferably formed with a pair of grounding restriction portions 310 and 321 facing the pair of grounding stoppers 126 in the third direction X. In this case, the movable range of the first ground piece 141C in the third direction X in the direction away from the second ground piece 142C is limited by the pair of ground stoppers 126 coming into contact with the pair of ground regulating portions 310 and 321. It is preferable that it is comprised. According to this configuration, in the state where the plug 100 is connected to the outlet 3, even if a large external force is applied to the plug 100 in the direction crossing the first direction Z, an “abnormal opening” occurs in the ground member 14C. Hateful. Therefore, there is an advantage that the reliability of the outlet 3 is not easily lowered. Moreover, since the ground door 15C is provided, intrusion of foreign matter from the ground insertion hole 313 into the case 30 is prevented when the plug 100 is not connected, and this also reduces the reliability of the outlet 3. Is suppressed. Here, since the pair of grounding stoppers 126 protrude from both end edges in the second direction Y of the first grounding piece 141C, “abnormal opening” can be prevented without interfering with the grounding door body 15C. However, this configuration is not essential for the outlet 3, and the pair of grounding stoppers 126 and the pair of grounding regulating portions 310 and 321 may be omitted as appropriate.
