(1) Overview As shown in FIGS. 2 to 4, the wiring equipment device 10 according to the present embodiment includes the wiring equipment 1 and the wiring equipment cover 2 (hereinafter, also simply referred to as “cover”) that covers the wiring equipment 1. And have.

In the present embodiment, the wiring device 1 has a function of an outlet (Outlet) to which a plug of the electric device is connected to supply electric power to the electric device. Here, as an outlet, an example is an AC 100V outlet with a grounding electrode, and a two-port type outlet capable of connecting two plugs at the same time. Further, in the present embodiment, as the wiring equipment device 10, an outdoor wiring equipment device 10 attached to an outer wall of a building is illustrated. The building in which the wiring equipment 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 the present embodiment, the wiring device device 10 is an outdoor outlet device.

The wiring equipment device 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 equipment 1. In the wiring appliance device 10, power can be supplied from the wiring appliance 1 to the electrical equipment by connecting the plug 100 of the electrical equipment (see FIG. 9) to the wiring appliance 1. Here, the wiring instrument device 10 is in a state in which the connection surface 311 in which the insertion holes 312 (see FIG. 4) into which the plug blades 102A and 102B (see FIG. 9) of the plug 100 are inserted is formed in the wiring instrument 1 is directed downward. Then, it is attached to the construction surface 900 (see FIG. 9). Therefore, the plug 100 is connected to the wiring device 1 from below, and rainwater is less likely to enter the wiring device 1 from the insertion hole 312 and the ground insertion hole 313.

The wiring equipment device 10 configured in this way is installed in, for example, 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 device 10, power can be supplied from the wiring device 1 to the electric vehicle via the charging cable, and the electric vehicle can be charged. Becomes possible. The "electric vehicle" referred to here is a vehicle having a storage battery and traveling by using the 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. Further, the electric vehicle may be a senior car, a two-wheeled vehicle (electric motorcycle), a tricycle, an electric bicycle, or the like. Further, the application of the wiring appliance device 10 is not limited to charging an electric vehicle, and the wiring appliance device 10 may be used for supplying electric power to various electric devices such as lighting appliances and electric tools.

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

(2) Overall Configuration The overall configuration of the wiring equipment device 10 according to the present embodiment will be described in detail below.

In the present embodiment, the direction perpendicular (orthogonal) to the horizontal plane in the state where the wiring equipment device 10 is attached to the outer wall surface of the building which is the construction surface 900 is defined as the "vertical direction", and the wiring equipment device 10 is The lower part (vertical direction) when viewed from the front is described as "lower part". Further, a direction orthogonal to the vertical direction and parallel to the construction surface 900 will be referred to as a "left-right direction", and the wiring fixture device 10 will be described as "right" on the right side and "left side" on the left side when viewed from the front. Further, a direction orthogonal to both the vertical direction and the horizontal direction, that is, a direction orthogonal to the construction surface 900 will be referred to as a "front-back direction", and the wiring fixture device 10 side as viewed from the construction surface 900 will be described as "front". The arrows indicating "vertical direction", "horizontal direction", and "front-back direction" in the drawings are shown for the sake of explanation only and do not involve any substance.

However, these directions are not intended to limit the directions in which the wiring device device 10 is used. For example, when the wiring equipment device 10 is mounted on the floor surface instead of the wall surface, the "front-back direction" is the direction perpendicular to the horizontal plane, and the "vertical direction" and the "left-right direction" are the directions parallel to the horizontal plane. .. Further, even when the wiring device device 10 is mounted on the wall surface, the "vertical direction" is the direction parallel to the horizontal plane (that is, the horizontal direction), and the wiring device device 10 is mounted on the wall surface, so that the "left-right direction" is changed. The direction is perpendicular to the horizontal plane.

(2.1) Configuration of Wiring Instrument First, the configuration of the wiring instrument 1 will be described with reference to FIGS. 2 to 6. The wiring device 1 has 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 has a case 30 and built-in parts 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, an inner cover 31, a first case 32, and a second case 33. The case 30 is made of, for example, urea resin. The first case 32 and the second case 33 are combined and integrated in the front-rear direction so as to cover the rear surface of the first case 32 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 (first case 32 and second case 33). The lower surface of the inner cover 31 constitutes a connecting surface 311. The connecting surface 311 is formed with an insertion hole 312 and a grounding insertion hole 313 into which the plug blades 102A and 102B of the plug 100 and the grounding plug blade 102C (see FIG. 9) are inserted. The internal configuration of the outlet 3 will be described in detail in the column of "(3) Details of the outlet".

The outlet 3 has a terminal portion 180 (see FIG. 7) for connecting an electric wire. Here, the terminal portion 180 is an electric wire insertion type quick connection terminal in which an electric wire is connected by inserting an electric wire through 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, a pair of power supply wires and a ground wire (earth wire), are connected to the outlet 3. Further, the terminal portion 180 has a feed terminal for feed wiring, and a maximum of six electric wires can be connected. A release operation hole 341 for inserting a jig such as a screwdriver 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 screwdriver from the release operation hole 341, the holding state of the electric wire in the terminal portion 180 is released.

Further, the outlet 3 has an extension terminal plate 35 constituting 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 long strip shape in the vertical direction. The upper end portion of the extension terminal plate 35 is electrically connected to the grounding 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 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 is composed of a rectangular frame-shaped frame 41 that is long in the vertical direction and a storage portion 42 that protrudes forward from the front surface of the frame 41. The body 4 is made of, for example, ASA (Acrylate Styrene Acrylonitrile) resin. At the lower end of the frame 41, a ground terminal hole 411 is formed at a position corresponding to the lower end of the extension terminal plate 35. The terminal screw 37 is tightened to the extension terminal plate 35 from the front surface of the frame 41 through the ground terminal hole 411, so that the extension terminal plate 35 and the terminal screw 37 form a ground terminal. That is, the ground 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 diagonally upward. As a result, the amount of protrusion of the storage portion 42 from the front surface of the frame body 41 increases as it approaches the lower end edge of the storage portion 42 in the vertical direction. In the present embodiment, the front surface of the storage portion 42 is not a flat surface, but a curved surface curved so as to be convex diagonally upward. The inside of the storage portion 42 is hollow. 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 mounting pieces 331 for passing the fixing screw 81 project from both side surfaces in the left-right direction of the second case 33. The outlet 3 is fixed to the body 4 by the fixing screw 81. With the outlet 3 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 the present embodiment, the outlet 3 is held by the body 4 in a state of being tilted in 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 done. Here, the outlet 3 is held by the body 4 in a state where the entire case 30 is tilted so that 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 tilted in the vertical direction. ing. As a result, the insertion directions of the plug blades 102A and 102B and the ground plug blade 102C of the plug 100 connected to the wiring device 1 are slightly inclined with respect to the vertical direction. That is, the plug 100 is connected to the connection surface 311 from diagonally forward, not from below (directly below) in the vertical direction.

The waterproof plate 5 is arranged 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 one size smaller than the frame 41 of the body 4. The waterproof plate 5 is made of, for example, a soft vinyl chloride resin. A groove 51 is formed on the outer peripheral portion of the front surface of the waterproof plate 5 along substantially the entire circumference except for the lower portion. By fitting the rib 412 formed on the rear surface of the frame body 41 into the groove 51, rainwater is prevented from entering the space between the waterproof plate 5 and the body 4. Further, ribs 52 are formed on the outer peripheral portion of the rear surface of the waterproof plate 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. Further, in the waterproof plate 5, a wire passage hole 54 for wire passage is formed at a position corresponding to the second opening 422.

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

According to the above-described configuration, in the wiring fixture 1, the body 4 and the waterproof plate 5 are attached to the construction surface 900 by 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 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 is 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 with the decorative plate 82. Further, when the cover 2 is attached 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 Cover for Wiring Equipment 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 on the rear surface and the lower surface of the cover body 6. Specifically, the cover main body 6 integrally has a main wall portion 60, a first side wall 61, and a second side wall 62. The main wall portion 60 covers the wiring fixture 1 from at least one of the front side and the upper side. 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 to cover a part of the wiring device 1 instead of covering the entire wiring device 1. In the present embodiment, the cover main body 6 is formed so as to cover at least the storage portion 42 in which the outlet 3 is housed among the wiring fixtures 1 from the front, the upper side, the left side, and the 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 open rear surfaces and lower surfaces, and is formed in a hollow rectangular parallelepiped shape long in the vertical direction. In the present embodiment, the thicknesses of the front wall 601 and 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 vertical direction. The upper wall 602 is configured to project rearward from the upper edge of the front wall 601. The upper wall 602 is formed in the shape of a rectangular plate long in the left-right direction. The first side wall 61 is configured to project rearward from the left edge of the front wall 601. The second side wall 62 is configured to project 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, 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 both curved with the 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 first. It is curved with a radius of curvature of 2. The first radius of curvature is larger 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, the term "orthogonal" used in the present disclosure means not only a state in which they intersect at exactly 90 degrees, but also a state in which they are substantially 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. That is, the upper wall 602 is slightly lowered forward, and a gradient is provided on the upper surface of the cover body 6 to the extent that rainwater does not collect.

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

By the way, the cover body 6 is made of a flame-retardant resin containing a bright pigment. The "brilliant pigment" referred to here is a pigment composed of, for example, metal powder (metal flakes), mica, titanium oxide, glass flakes, etc., and exhibits a metallic luster or a pearl-like luster. In the present embodiment, a metal powder (aluminum flakes as an example) is used as the bright pigment, and the flame-retardant resin constituting the cover body 6 is colored with a metallic color. That is, the flame-retardant resin constituting the cover body 6 is a so-called uncoated (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 uncoated resin, it is possible to realize coloring such as metallic color on the finished product (cover body 6) even if it is unpainted (paintless). The base material of the flame-retardant resin is, for example, polycarbonate.

Further, the "flammable resin" referred to here is a resin having flame retardancy rather than flammability when the flammability of the resin is classified into flammability and flame retardancy (including nonflammability). is there. In the present embodiment, the cover body 6 has a flame retardancy of UL94 V-2 or higher. "UL94" is a flame retardancy evaluation standard established by UL (Underwriters Laboratories). There are six UL94 standard grades: "HB" in the horizontal combustion test, "V-2", "V-1", "V-0", "5VA", and "5VB" in the vertical combustion test. There is a grade. These six grades have the lowest flame retardancy of "HB", and flame retardant in the order of "HB", "V-2", "V-1", "V-0", "5VB", and "5VA". The sex becomes high. That is, the cover body 6 having a flame retardancy of UL94 V-2 or higher is "V-2", "V-1", "V-0", "5VB" and "5VA" except for "HB". It will have one of the flame retardancy of. A resin having a flame retardancy of UL94 V-2 or higher has a property of burning in the atmosphere while being exposed to a flame, but extinguishing the fire when separated from the flame (self-extinguishing property). In other words, the flame-retardant resin used as the material of the cover body 6 preferably has a flame-retardant property of "V-2" or higher in the UL94 standard when the sample thickness is, for example, 2.5 mm.

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

Further, in the cover main body 6, at least one surface of each of the first side wall 61 and the second side wall 62 on the side opposite to the wiring device 1 is made of a textured (embossed) uneven surface. The "texture processing" referred to here is a process of forming a fine uneven wrinkle pattern (texture) on the surface of the cover body 6 at the time of molding the cover body 6. In the present embodiment, the left side surface (one surface on the side opposite to the wiring device 1) of the first side wall 61 of the cover main body 6 is composed of the uneven surface 611, and the second side wall 62 (the side opposite to the wiring device 1). One surface) is composed of an uneven surface 621. Further, among the cover main body 6, the front surface 603 of the front wall 601 and the upper surface of the upper wall 602 are also made of a similarly textured uneven surface. As a result, even if the cover body 6 is unpainted (paintless), it is possible to realize a texture similar to painting due to the 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.

Further, the cover main body 6 has a first rib 63, a second rib 64, and a hook claw 65 as a structure for connecting to the wiring device 1, as shown in FIG. The first rib 63 projects 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 projects 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 hook claw 65 projects 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 attachment portion 604 of the cover main 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 attached to the attachment portion 604 with an adhesive or an adhesive tape, or may be attached to the attachment portion 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 is still 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.

Further, the blade receiving member 14B has basically the same configuration as the blade receiving member 14A, and has a substantially symmetrical relationship in the second direction Y. Therefore, if "A" in the reference numeral is read as "B" in the description of the blade receiving member 14A and the description of the direction in the second direction Y is reversed, the blade receiving member which is the "second blade receiving member" is used. It becomes the explanation about 14B. Therefore, in the following, among the blade receiving members 14B, the same configuration as the blade receiving member 14A will be omitted as appropriate.

The pair of intermediate portions 113 are inclined with respect to the first direction Z so as to approach each other as they approach the insertion holes 312. The inclination angle of the intermediate portion 113 with respect to the first direction Z is smaller than the inclination angle of the inclined portion 112 with respect to the first direction Z.

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

The first grounding piece 141C and the second grounding piece 142C are arranged side by side in the third direction X so that the first grounding piece 141C is on the opposite side to the blade receiving members 14A and 14B. The grounding member 14C further has 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 on the opposite side of the grounding insertion hole 313 in the first direction Z.

The first grounding piece 141C has a base portion 121, an inclined portion 122, and a guide portion 124. The second grounding piece 142C has a base portion 131, an inclined portion 132, an intermediate portion 133, and a guide portion 134. In the first grounding piece 141C and the second grounding piece 142C, the bases 121 and 131 are connected to each other by the connecting piece 143A. The first grounding piece 141C and the second grounding piece 142C have an asymmetrical shape in the third direction X.

The bases 121 and 131 face each other and are arranged substantially parallel to the first direction Z. The inclined portions 122 and 132 project from the edge of the base portions 121 and 131 on the ground insertion hole 313 side 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 they approach the ground insertion hole 313. The intermediate portion 133 projects from the edge of the inclined portion 132 on the ground insertion hole 313 side toward the ground insertion hole 313. The intermediate portion 133 is inclined with respect to the first direction Z so that the closer to the ground insertion hole 313, the closer to the first ground piece 141C. The inclination angle of the intermediate portion 133 with respect to the first direction Z is smaller than the inclination angle of the inclined portion 132 with respect to the first direction Z. The guide portion 124 projects from the edge of the inclined portion 122 on the ground insertion hole 313 side toward the ground insertion hole 313. The guide portion 134 projects from the edge of the intermediate portion 133 on the ground insertion hole 313 side toward the ground insertion hole 313. The guide portions 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 portion 124 with respect to the first direction Z is smaller than the inclination angle of the guide portion 134 with respect to the first direction Z, and is larger than the inclination angle of the intermediate portion 133 with respect to the first direction Z.

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

According to this configuration, the distance between the first grounding piece 141C and the second grounding piece 142C in the third direction X is 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. It is minimized by the grounding electrode holding portion 125 composed of the portions. That is, in the corner portion 136 including the connecting portion between the intermediate portion 133 and the guide portion 134, the distance between the first grounding piece 141C and the second grounding piece 142C in the third direction X is not the minimum. The distance between the first grounding piece 141C and the second grounding piece 142C in the grounding electrode holding portion 125 is set to be smaller than the diameter of the grounding plug blade 102C. On the other hand, the distance between the first grounding piece 141C and the second grounding piece 142C at the edge of the guide portions 124 and 134 on the grounding insertion hole 313 side is set to be larger than the diameter of the grounding 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, showing a cross section of the periphery of the blade receiving member 14B as viewed from one of the third directions X, and the periphery of the grounding member 14C 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 same applies to the relationship between the blade receiving member 14A and the grounding member 14C.

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

The blade receiving member 14B is configured to sandwich the plug blade 102B between the first blade receiving piece 141B and the second blade receiving piece 142B in the power supply electrode holding portion 115 located at the first distance L1 from the connecting surface 311 in the first direction Z. Has been done. Specifically, the power supply pole holding portion 115 including the connecting portion between the intermediate portion 113 and the guide portion 114 is located at the position of the first distance L1 from the connecting surface 311 in the first direction Z.

The grounding member 14C is configured to sandwich the grounding plug blade 102C between the first grounding piece 141C and the second grounding piece 142C by the grounding electrode holding portion 125 located at the second distance L2 from the connecting surface 311 in the first direction Z. ing. Specifically, the grounding electrode holding portion 125 including 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 is a second distance from the connecting surface 311 in the first direction Z. It is in the position of L2.

Here, regarding 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 the 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 the value (L1 + L0) obtained by adding a predetermined amount L0 to the first distance L1. That is, the predetermined quantity L0, the first distance L1 and the second distance L2 have a relationship of “L2> L1 + L0”.

Further, in the first direction Z, the distance from the first grounding piece 141C and the second grounding piece 142C to the connecting surface 311 is defined as the third distance L3. Similarly, in the first direction Z, the distance from the first blade receiving piece 141A and the second blade receiving piece 142A to the connecting surface 311 is defined as the fourth distance L4. Then, for the third distance L3 and the fourth distance L4, the predetermined amount L0, which is the difference in the insertion amount from the connection surface 311 between the grounding 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 (L4 + L0) obtained by adding a predetermined amount L0 to the fourth distance L4 in both the first grounding piece 141C and the second grounding piece 142C. That is, the predetermined quantity 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 work 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, exemplifying 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, the ground plug blade 102C first comes into contact with the ground member 14C, as shown in FIG. 11A. In the state shown in FIG. 11A, the plug 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 attached to the blade receiving member 14B. The grounding plug blade 102C comes into contact with the grounding member 14C before the contact. At this time, even if the ground plug blade 102C is tilted with respect to the first direction Z due to the plug 100 being inserted at an angle, the ground plug blade 102C is a first ground piece 141C and a second ground piece. Contact any of 142C. However, in the state shown in FIG. 11A, since the ground plug blade 102C does not reach the ground electrode holding portion 125 of the ground member 14C, neither the plug blade 102B nor the ground 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 comes into contact with the blade receiving member 14B, and then, as shown in FIG. 11B, the plug blade 102B causes the blade receiving member 14B. Reach the power pole holding portion 115 of. Therefore, 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, and the blade receiving member 14B is in contact with the plug blade 102B to some extent. It is electrically connected. However, in the state shown in FIG. 11B, the grounding plug blade 102C has not reached the grounding electrode holding portion 125 of the grounding 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 before the ground plug blade 102C reaches the ground electrode holding portion 125. Reaches the power pole holding portion 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 by the grounding electrode holding portion 125, and the grounding member 14C is electrically connected to the grounding plug blade 102C with a certain amount of contact pressure. Is connected. Here, from the state shown in FIG. 11B until the grounding plug blade 102C reaches the grounding electrode holding portion 125, the guide portion 124 of the grounding member 14C is inclined with respect to the first direction Z. , The force (insertion force) required for inserting the plug 100 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, the ground plug blade 102C first comes into contact with the ground member 14C. After that, 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 grounding plug blade 102C comes into contact with the grounding 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 grounding plug blade 102C is the first. The configuration may be such that it is sandwiched between the 1 grounding piece 141C and the 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, to the connecting surface 311 in the blade receiving member 14B 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 supply electrode holding portion 115, the distance from the connection surface 311 to this position is set 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, when the grounding plug blade 102C comes into contact with either the first grounding piece 141C or the second grounding piece 142C, the grounding plug blade 102B comes into contact with the blade receiving member 14B. It is particularly useful for the 102C to come into contact with the 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 has basically the same configuration as the door body 15A, and has a substantially symmetrical relationship in the second direction Y. Therefore, if "A" in the reference numeral is read as "B" in the description of the door body 15A and the description of the direction in the second direction Y is reversed, the description of the door body 15B is obtained. Further, the grounding door body 15C also has basically the same configuration as the door body 15A. Therefore, in the following, among the door bodies 15A and 15B and the grounded door body 15C, the same configuration as the door body 15A will be omitted as appropriate. Further, the elastic member 16B has basically the same configuration as the elastic member 16A, and has a substantially symmetrical relationship in the second direction Y. Therefore, if "A" in the reference numeral is read as "B" in the description of the elastic member 16A and the description of the direction in the second direction Y is reversed, the description of the elastic member 16B is obtained. Further, the ground elastic member 16C also has basically the same configuration as the elastic member 16A. Therefore, in the following, among the elastic members 16A and 16B and the grounded elastic member 16C, 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-shaped support portion 151 extending along the first direction Z, and an opening / closing portion 152 protruding from the end of the support portion 151 on the insertion hole 312 side in the thickness direction of the support portion 151. Have. The door body 15A is formed by the support portion 151 and the opening / closing portion 152 in a substantially L shape when viewed from one of the third directions X. The support portion 151 is arranged on the side opposite to the second blade receiving piece 142A in the second direction Y with respect to the first blade receiving piece 141A. The support portion 151 is configured to be rotatable around an end portion opposite to the insertion hole 312 as a fulcrum. The opening / closing portion 152 is configured to be able to move forward and backward with respect to the space between the insertion hole 312 and the blade receiving member 14A as the support portion 151 rotates. As a result, the door body 15A moves between the closed position that covers the blade receiving member 14A as seen from the insertion hole 312 and the open position that exposes the blade receiving member 14A as seen from the insertion hole 312.

Further, the amount of protrusion of the opening / closing portion 152 from the support portion 151 becomes smaller as it approaches the insertion hole 312 in the first direction Z. As a result, the surface facing the insertion hole 312 constitutes an inclined surface 153 that is inclined with respect to the first direction Z. Further, the door body 15A has a door stopper 154. The door stopper 154 is formed on the surface of the door body 15A on the side 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 grounding door body 15C. The function of the door stopper 154 will be described in the column of "(3.5) Abnormal opening prevention structure".

The elastic member 16A is made of, for example, a metal leaf spring. The elastic member 16A is arranged on the side opposite 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 16A is fixed to the inner surface of the case 30. The elastic member 16A exerts an elastic force on 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, when the plug blade 102A is not inserted into the insertion hole 312, the door body 15A is positioned at the closed position due to the elastic force of the elastic member 16A. Therefore, the insertion hole 312 is closed from the inside of the case 30 by the opening / closing portion 152 of the door body 15A. In this state, when the plug blade 102A is inserted through the insertion hole 312, the tip end portion 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 portion 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. As a result, 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 due to the elastic force of the elastic member 16A.

(3.5) Abnormal Opening Prevention Structure Next, a structure for preventing "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 a main part of the outlet 3 and omitting illustrations other than the inner cover 31 and the blade receiving block 140. The term "abnormal opening" as used herein means that the blade receiving members 14A and 14B and the grounding member 14C open beyond the movable range in normal use of the wiring device device 10. For example, in a 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 intersecting the first direction Z, the blade receiving member 14A, from the plug blades 102A, 102B or the ground plug blade 102C, A large external force acts on the 14B or the grounding member 14C. Specifically, when the plug 100 is pulled out by holding the power cord, so-called "sliding", or when a person's foot is caught in the power cord, the above-mentioned external force acts and "abnormal opening" occurs. May occur. In particular, when the connection surface 311 is flat and does not have a structure for holding the plug body 101 as in the present embodiment, the plug 100 is likely to be tilted 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, which may interfere with the function as an outlet. is there. In this embodiment, as a countermeasure against such "abnormal opening", the configuration described below is adopted.

That is, as shown in FIG. 1A, 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. The pair of stoppers 116 are formed so as to project from the guide portion 114 of the first blade receiving piece 141A on both sides in the third direction X. The pair of stoppers 116 are set so as to project at least from both end edges of the third direction X in the door body 15A to both sides of the third direction X. The inner cover 31 of the case 30 is formed with a pair of regulating portions 314 facing the pair of stoppers 116 in the second direction Y. The pair of restricting portions 314 face the pair of stoppers 116 from the side opposite to the second blade receiving piece 142A in the second direction Y. The pair of regulating portions 314 are arranged on both sides of the insertion hole 312 in the third direction X in the inner cover 31.

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

Here, the pair of stoppers 116 are 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 regulation wall 318 provided on the inner cover 31 of the case 30 faces from the side opposite to the first blade receiving piece 141A in the second direction Y. Therefore, the movable range of the second blade receiving piece 142A in the direction away from the first blade receiving piece 141A is limited by coming into contact with the regulation wall 318 even if there is no stopper. On the other hand, regarding the first blade receiving piece 141A, since the door body 15A which is a movable member is located on the opposite side of the second blade receiving piece 142A in the second direction Y, a regulation wall cannot be provided. .. Therefore, with respect to the first blade receiving piece 141A, the movable range in the direction away from the second blade receiving piece 142A is limited by providing a pair of stoppers 116 protruding from both end edges in the third direction X.

Here, the inner cover 31 is formed with a protrusion 316 located between one of the regulating portions 314 and the second blade receiving piece 142A. The protrusion 316 is arranged between 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 142A A preliminary opening is performed to form a predetermined gap between the 142A and the 142A. Since the preliminary opening is performed, the force required for inserting the plug blade 102A into the blade receiving member 14A is smaller than that in the case where the preliminary opening is not performed. A similar protrusion 316 for preliminary opening is also provided for the blade receiving member 14B (see FIG. 1B).

Further, in the present embodiment, a configuration for preventing "abnormal opening" is also applied to the door body 15A. That is, as shown in FIG. 9, a door stopper 154 is formed on the surface of the door body 15A on the side opposite to the first blade receiving piece 141A in the second direction Y. The door stopper 154 is formed so as to project 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 facing the door stopper 154 in the second direction Y. The door restricting unit 315 faces the door stopper 154 from the side opposite to the first blade receiving piece 141A in the second direction Y.

As a result, the door body 15A is limited in the movable range in the direction away from the first blade receiving piece 141A in the second direction Y 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 second direction Y in the direction away from the first blade receiving piece 141A is defined by the clearance between the door stopper 154 and the door regulating portion 315.

By the way, the outlet 3 includes a blade receiving member 14B which is a "second blade receiving member" in addition to the blade receiving member 14A which is a "first blade receiving member". However, the pair of stoppers 116 are provided only on the blade receiving member 14A among the blade receiving members 14A and 14B. The reason why the blade receiving member 14B is not provided with the stopper is as follows.

That is, in the outlet 3, a guide wall 317 is provided as a means for preventing the plug 100 from tilting in the third direction X while the plug 100 is connected. Specifically, as shown in FIG. 1B, the case 30 has a guide wall 317 for preventing the plug blade 102B from tilting in 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 14B in the third direction X of the inner cover 31. As a result, the inclination of the plug blade 102B inserted through the insertion hole 312 in the third direction X 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 blade receiving member 14B is provided with a stopper, the stopper interferes with the guide wall 317. It will be. Therefore, in the present embodiment, the pair of stoppers 116 are provided only on the blade receiving member 14A among the blade receiving members 14A and 14B.

Further, in the wiring equipment device 10 according to the present embodiment, the case 30 is configured to be attached to the construction surface 900 in a direction in which the second direction Y intersects the construction surface 900. The blade receiving members 14A and 14B are arranged side by side in the second direction Y so that the blade receiving members 14A are on the construction surface 900 side. Further, 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, in the case of so-called "sliding" or when a person's foot is caught on the power cord, the first blade receiving piece 141A of the blade receiving member 14A which is closer to the construction surface 900 among the blade receiving members 14A and 14B. A large external force acts on the blade. That is, in such a case, since an external force hardly acts on the first blade receiving piece 141B of the blade receiving member 14B farther from the construction surface 900, the prevention of "abnormal opening" by the pair of stoppers 116 is the blade. Only the receiving member 14A is required.

On the other hand, with respect to the door body 15B, a configuration for preventing "abnormal opening" is applied as in the door body 15A. That is, the 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 movable range of the door body 15B in the direction away from the first blade receiving piece 141B in the second direction Y is limited by the contact of the door stopper 154 with the door restricting portion 315. As a result, although the first blade receiving piece 141B of the blade receiving member 14B itself does not have a structure for preventing "abnormal opening", the door body 15B makes the first blade receiving piece 142B away from the second blade receiving piece 142B to some extent. The movable range of the 1-blade receiving piece 141B is limited.

Further, as for the grounding member 14C, a configuration for preventing "abnormal opening" is applied as in the case of 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 grounding stoppers 126 are formed so as to project from the guide portion 124 of the first grounding piece 141C on both sides in the second direction Y. The pair of grounding stoppers 126 are set so as to project at least from both end edges of the second direction Y to both sides of the second direction Y in the grounding door body 15C. The case 30 is formed with a pair of grounding control portions 310 and 321 facing the pair of grounding stoppers 126 in the third direction X. The pair of grounding control units 310 and 321 face the pair of grounding stoppers 126 from the side opposite to the second grounding piece 142C in the third direction X. The ground control unit 310 is composed of a part of the inner cover 31, and the ground control unit 321 is a part of the first case 32.

As a result, the movable range of the first grounding piece 141C in the direction away from the second grounding piece 142C in the third direction X is limited by the contact of the pair of grounding stoppers 126 with the pair of grounding restricting portions 310 and 321. .. In other words, the movable range of the first grounding piece 141C in the direction X away from the second grounding piece 142C in the third direction X is defined by the clearance between the pair of grounding stoppers 126 and the pair of grounding restricting portions 310 and 321. ..

Here, the pair of grounding stoppers 126 are 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 side opposite to the first grounding piece 141C in the third direction X. Therefore, even if the second grounding piece 142C does not have a stopper, the movable range in the direction away from the first grounding piece 141C is limited by contacting the regulation wall 319.

According to this configuration, when the pair of stoppers 116 come into contact with the pair of regulating portions 314, 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. .. 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, "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 unlikely to decrease. Moreover, since the door body 15A is provided, foreign matter is prevented from entering the case 30 from the insertion hole 312 when the plug 100 is not connected, and this also suppresses a decrease in the reliability of the outlet 3.

Is preferable. According to this configuration, "abnormal opening" is prevented even in the door body 15A, so that "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. It is unlikely to occur. Therefore, there is an advantage that the reliability of the outlet 3 is less likely to decrease. However, this configuration is not essential for the outlet 3, and the door stopper 154 and the door regulation unit 315 may be omitted as appropriate.

Further, as in the present embodiment, the outlet 3 is arranged side by side with the "first blade receiving member" which is the blade receiving member 14A in the second direction Y, and is the "first plug blade" which 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, it is preferable that the pair of stoppers 116 are provided only on the blade receiving member 14A of the blade receiving member 14A and the blade receiving member 14B. In this case, it is preferable that the case 30 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 guide wall 317 provided on at least one side of the blade receiving member 14B can prevent the plug blade 102B from tilting in the third direction X. 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.

According to this configuration, when so-called "sliding" or when a person's foot is caught on the power cord, the first of the blade receiving members 14A and 14B, 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 an external force hardly acts on the first blade receiving piece 141B of the blade receiving member 14B farther from the construction surface 900, the prevention of "abnormal opening" by the pair of stoppers 116 is the blade. Only the receiving member 14A is required. However, this configuration is not essential for the outlet 3, and even if the blade receiving member 14A and the blade receiving member 14B are arranged side by side in the second direction Y so that the blade receiving member 14B is on the construction surface 900 side.
