　（１）概要
　本実施形態に係る配線器具装置１０は、図１～図３に示すように、配線器具１と、配線器具１を覆う配線器具用カバー２（以下、単に「カバー」ともいう）とを備えている。 (1) Outline As shown in FIGS. 1 to 3, the wiring device apparatus 10 according to the present 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.
　本実施形態において、配線器具１は、電気機器のプラグが接続されて電気機器への電力供給を行うコンセント（Outlet）の機能を有している。ここでは、コンセントとして、接地極付きの交流１００Ｖ用であって、２個のプラグを同時に接続可能な２個口タイプのコンセントを例示する。また、本実施形態では、配線器具装置１０として、建物の外壁に取り付けられる屋外用の配線器具装置１０を例示する。配線器具装置１０が設置される建物は、例えば戸建住宅、集合住宅、事務所、店舗又は介護施設等である。つまり、本実施形態では、配線器具装置１０は屋外用のコンセント装置である。 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 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.
　配線器具装置１０は、配線器具１に対して電線を電気的に接続した状態で、施工面（建物の外壁面）に取り付けられる。この配線器具装置１０においては、電気機器のプラグが配線器具１に接続されることによって、配線器具１から電気機器への電力供給が可能になる。ここで、配線器具装置１０は、配線器具１においてプラグの栓刃（又はピン）が差し込まれる挿入孔３１２（図３参照）及び接地挿入孔３１３（図３参照）が形成された接続面３１１を下方に向けた状態で、施工面に取り付けられる。そのため、プラグは、配線器具１に対して下方から接続されることになり、挿入孔３１２及び接地挿入孔３１３から配線器具１内部へ雨水が浸入しにくくなる。 The wiring device apparatus 10 is attached to a construction surface (outer wall surface of a building) in a state where electric wires are electrically connected to the wiring device 1. In the wiring device apparatus 10, the plug of the electric device is connected to the wiring device 1, so that power can be supplied from the wiring device 1 to the electric device. Here, the wiring device device 10 includes a connection surface 311 in which an insertion hole 312 (see FIG. 3) and a ground insertion hole 313 (see FIG. 3) into which the plug blade (or pin) of the plug is inserted in the wiring device 1 are formed. It is attached to the construction surface in a state of facing downward. Therefore, the plug 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.
　このように構成される配線器具装置１０は、例えばガレージ等に設置され、電動車両の充電に用いられる。つまり、電動車両と接続された充電ケーブルのプラグが、配線器具装置１０に対して接続されることにより、配線器具１から充電ケーブルを介して電動車両に電力供給可能になり、電動車両の充電が可能になる。ここでいう「電動車両」は、蓄電池を有し、蓄電池に蓄積された電気エネルギーを用いて走行する車両である。電動車両は、例えば、電動機の出力によって走行する電気自動車又はエンジンの出力と電動機の出力とを組み合わせて走行するプラグインハイブリッド車等である。また、電動車両は、シニアカー、二輪車（電動バイク）、三輪車又は電動自転車等であってもよい。さらに、配線器具装置１０の用途は電動車両の充電用に限らず、例えば照明器具及び電動工具等、各種の電気機器への電力供給に配線器具装置１０が用いられてもよい。 The wiring device apparatus 10 configured as described above is installed in, for example, a garage and used for charging an electric vehicle. That is, when the plug of the charging cable connected to the electric vehicle is connected to the wiring device apparatus 10, electric power can be supplied from the wiring device 1 via the charging cable to the electric vehicle. It becomes 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.
　ただし、本実施形態に係る配線器具装置１０は、プラグの抜け止めとなるロック機構を有しないコンセント装置である。そのため、配線器具装置１０は、例えば給湯器のように長期にわたってプラグを接続したままで使用される電気機器よりも、電動車両のようにプラグの抜き差しが頻繁に行われる用途に適している。 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 from coming off. Therefore, the wiring device apparatus 10 is suitable for an application in which the plug is frequently inserted and removed, such as an electric vehicle, rather than an electric device that is used with the plug connected for a long period of time, such as a water heater.
　（２）全体構成
　以下、本実施形態に係る配線器具装置１０の全体構成について詳しく説明する。 (2) Overall Configuration Hereinafter, the overall configuration of the wiring device apparatus 10 according to the present embodiment will be described in detail.
　本実施形態では、施工面である建物の外壁面に配線器具装置１０が取り付けられた状態での、水平面に対して垂直な（直交する）方向を「上下方向」とし、配線器具装置１０を正面から見て下方（鉛直方向）を「下方」として説明する。また、上下方向と直交し、かつ施工面に平行な方向を「左右方向」とし、配線器具装置１０を正面から見て右方を「右方」、左側を「左方」として説明する。さらに、上下方向と左右方向との両方に直交する方向、つまり施工面に直交する方向を「前後方向」とし、施工面から見て配線器具装置１０側を「前方」として説明する。図面中の「上下方向」、「左右方向」及び「前後方向」を示す矢印は説明のために表記しているに過ぎず、実体を伴わない。 In the present embodiment, the direction perpendicular to (orthogonal to) the horizontal plane in a state where the wiring apparatus device 10 is attached to the outer wall surface of the building that is the construction surface is defined as the “vertical direction”, and the wiring apparatus device 10 is viewed from the front. The downward direction (vertical direction) as viewed from the top is described as “downward”. In addition, a description will be given assuming that a direction orthogonal to the vertical direction and parallel to the construction surface is “left-right direction”, the right side when viewing the wiring device apparatus 10 from the front is “right”, and the left side is “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 will be referred to as “front-rear direction”, and the wiring device apparatus 10 side as viewed from the construction surface will be 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.
　ただし、これらの方向は配線器具装置１０の使用方向を限定する趣旨ではない。例えば、配線器具装置１０が壁面ではなく床面に取り付けられる場合には、「前後方向」は水平面に対して垂直な方向となり、「上下方向」及び「左右方向」は水平面に平行な方向となる。また、配線器具装置１０が壁面に取り付けられる場合でも、「上下方向」が水平面に平行な方向となる向き（つまり横向き）で、配線器具装置１０が壁面に取り付けられることにより、「左右方向」は水平面に垂直な方向となる。 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）配線器具の構成
　まず、配線器具１の構成について、図１～図５を参照して説明する。配線器具１は、本体ユニット３と、本体ユニット３を保持するボディ４と、ボディ４の後面に取り付けられる防水板５とを有している。 (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 a main unit 3, a body 4 that holds the main unit 3, and a waterproof plate 5 that is attached to the rear surface of the body 4.
　本体ユニット３は、ケース３０と、ケース３０内に収納される刃受部材等の内蔵部品とを有している。ケース３０は、内カバー３１、第１ケース３２及び第２ケース３３の３つの部材が組み合わされて構成されている。ケース３０は、例えばユリア樹脂製である。第１ケース３２及び第２ケース３３は、第１ケース３２の後面を第２ケース３３で覆うように、前後方向において組み合わされて一体化される。第１ケース３２及び第２ケース３３は、互いに組み合わされることによって、下面に開口を有する箱状の内ボディを構成する。内カバー３１は、内ボディ（第１ケース３２及び第２ケース３３）の下面の開口を塞ぐように第１ケース３２及び第２ケース３３と組み合わされる。内カバー３１の下面は、接続面３１１を構成する。接続面３１１には、プラグの栓刃（又はピン）が差し込まれる挿入孔３１２及び接地挿入孔３１３が形成されている。 The main unit 3 includes a case 30 and built-in components such as a blade receiving member 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 has an insertion hole 312 and a ground insertion hole 313 into which a plug blade (or pin) of the plug is inserted.
　本体ユニット３は、電線を接続するための端子部を有している。ここでは、端子部は、ケース３０（第２ケース３３）の後面に形成された端子孔３４から電線を差し込むことによって電線が接続される、電線差込式の速結端子である。本実施形態では、本体ユニット３に対して、一対の電源線及び接地線（アース線）の合計３本の電線が接続される。さらに、端子部は、送り配線用の送り端子を有しており、最大で６本の電線が接続可能である。ケース３０の後面における端子孔３４の側方には、ドライバ等の治具を挿入するための解除操作孔３４１が形成されている。解除操作孔３４１からドライバ等の治具が挿入されることで、端子部における電線の保持状態が解除される。 The main unit 3 has a terminal portion for connecting an electric wire. Here, the terminal portion is a wire insertion type fast connection terminal to which the 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 (ground line) are connected to the main unit 3. Furthermore, the terminal portion has a feed terminal for feed wiring, and a maximum of 6 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 screwdriver from the release operation hole 341, the holding state of the electric wire in the terminal portion is released.
　また、本体ユニット３は、電気機器の接地線を接続するためのねじ式端子を構成する延長端子板３５を有している。延長端子板３５は、導電性の金属板からなり、上下方向に長い帯状に形成されている。延長端子板３５の上端部は、ケース３０（第２ケース３３）の後面から差し込まれることによって、本体ユニット３内にて、端子部の接地極と電気的に接続される。延長端子板３５の下端部は、一対の保持ねじ３６によってボディ４の後面に固定される。 The main unit 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 within the main unit 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.
　ボディ４は、上下方向に長い矩形枠状の枠体４１と、枠体４１の前面から前方に突出した収納部４２とで構成されている。ボディ４は、例えばＡＳＡ（Acrylate Styrene Acrylonitrile）樹脂製である。枠体４１の下端部において、延長端子板３５の下端部に対応する位置には、接地端子孔４１１が形成されている。この接地端子孔４１１を通して、枠体４１の前面から端子ねじ３７が延長端子板３５に締め付けられることにより、延長端子板３５と端子ねじ３７とで接地用端子が構成される。つまり、延長端子板３５に対して、電気機器の接地線が電気的に接続可能となる。 The body 4 includes a rectangular 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. 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.
　収納部４２の前面は、枠体４１の前面に対して平行ではなく、斜め上方に向けて傾斜している。これにより、枠体４１の前面からの収納部４２の突出量は、上下方向において収納部４２の下端縁に近づく程に大きくなる。本実施形態では、収納部４２の前面は平面ではなく、斜め上方に凸となるように湾曲した湾曲面である。収納部４２の内部は空洞である。収納部４２の下面には第１開口部４２１が形成され、収納部４２の後面には第２開口部４２２が形成されている。 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.
　本体ユニット３は、収納部４２の内部空間に収納される。第２ケース３３の左右方向の両側面からは、固定ねじ８１を通すための一対の取付片３３１が突出している。本体ユニット３は、固定ねじ８１によってボディ４に固定される。本体ユニット３がボディ４に固定された状態で、収納部４２の第１開口部４２１からは、本体ユニット３の下面（接続面３１１）が露出する。言い換えれば、ボディ４は、本体ユニット３の接続面３１１を露出させた状態で、本体ユニット３を保持する。 The main unit 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 main unit 3 is fixed to the body 4 by a fixing screw 81. In a state where the main unit 3 is fixed to the body 4, the lower surface (connection surface 311) of the main unit 3 is exposed from the first opening 421 of the storage unit 42. In other words, the body 4 holds the main unit 3 with the connection surface 311 of the main unit 3 exposed.
　本実施形態では、本体ユニット３は、第１開口部４２１から露出する接続面３１１が鉛直方向の下方（真下）よりもやや前方を向くように、上下方向に対して傾いた状態でボディ４に保持されている。ここでは、接続面３１１だけでなく、第１ケース３２の後面及び第２ケース３３の前面も上下方向に対して傾斜するように、本体ユニット３はケース３０全体が傾いた状態でボディ４に保持されている。これにより、配線器具１に接続されるプラグの栓刃（又はピン）の挿入方向は、上下方向に対してやや傾斜した方向となる。つまり、プラグは接続面３１１に対して鉛直方向の下方（真下）からではなく、斜め前方から接続されることになる。 In the present embodiment, the main body unit 3 is attached to the body 4 in a state of being inclined 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. Is retained. 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. Has been. Thereby, the insertion direction of the plug blade (or pin) of the plug connected to the wiring device 1 is slightly inclined with respect to the vertical direction. In other words, the plug is connected to the connection surface 311 from diagonally forward rather than from below (directly below) in the vertical direction.
　防水板５は、ボディ４の後面と施工面（壁面）との間に挟まれるように配置され、ボディ４の後面の第２開口部４２２からの雨水の浸入を防止する。防水板５は、ボディ４の枠体４１よりも一回り小さい矩形板状に形成されている。防水板５は、例えば軟質塩化ビニル樹脂製である。防水板５の前面の外周部には、下部を除く略全周に沿って溝５１が形成されている。この溝５１に対して、枠体４１の後面に形成されたリブ４１２が嵌ることによって、防水板５とボディ４との間の空間への雨水の浸入が防止される。さらに、防水板５の後面の外周部には、略全周に沿ってリブ５２が形成されている。このリブ５２によって、防水板５と施工面との間の空間への雨水の浸入が防止される。また、防水板５のうち、第２開口部４２２に対応する位置には、通線用の通線孔５４が形成されている。 The waterproof board 5 is disposed so as to be sandwiched between the rear surface of the body 4 and the construction surface (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. In addition, a through hole 54 is formed in the waterproof plate 5 at a position corresponding to the second opening 422.
　ここで、枠体４１には、取付ねじを通すための一対の取付孔４１３が形成されている。また、防水板５において、一対の取付孔４１３に対応する位置には、取付ねじを通すための一対の取付孔５３が形成されている。さらに、枠体４１の前面には、一対の取付孔４１３のうち下方の取付孔４１３を覆うための化粧板８２が装着される。化粧板８２は、ボディ４の前面に対して着脱可能に装着される。また、枠体４１の前面には、収納部４２の外周縁に沿ってカバー２取付用の周溝４１４が形成されている。 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.
　上述した構成により、配線器具１は、本体ユニット３と、ボディ４と、防水板５とが組み合わされた状態で、ボディ４及び防水板５が一対の取付ねじによって施工面に取り付けられる。このとき、施工面から引き出された電線は、通線孔５４及び第２開口部４２２を通して、収納部４２の内部空間に導入され、収納部４２内の本体ユニット３の端子部に接続される。施工面への配線器具１の取り付け後、化粧板８２がボディ４に装着されることによって、一対の取付ねじのうち下方の取付ねじが化粧板８２によって覆われる。さらに、カバー２が配線器具１に取り付けられることによって、一対の取付ねじのうち上方の取付ねじがカバー２によって覆われる。 With the configuration described above, the wiring device 1 has the body unit 4, the body 4, and the waterproof plate 5 combined with each other, and the body 4 and the waterproof plate 5 are attached to the construction surface with a pair of mounting screws. At this time, the electric wire drawn out from the construction surface 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 of the main unit 3 in the storage portion 42. After the wiring device 1 is attached to the construction surface, 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）配線器具用カバーの構成
　次に、カバー２の構成について図４～図６Ｃを参照して説明する。カバー２は、カバー本体６と、ラベル部材７とを備えている。 (2.2) Configuration of Wiring Device Cover Next, the configuration of the cover 2 will be described with reference to FIGS. 4 to 6C. The cover 2 includes a cover main body 6 and a label member 7.
　カバー本体６は、配線器具１を覆うように、箱状に形成されている。本実施形態では、カバー本体６の後面及び下面には開口が形成されている。具体的には、カバー本体６は、主壁部６０と、第１側壁６１と、第２側壁６２と、を一体に有している。主壁部６０は、配線器具１を前方と上方との少なくとも一方から覆う。第１側壁６１は、主壁部６０に隣接し、配線器具１を左側方から覆う。第２側壁６２は、主壁部６０に隣接し、配線器具１を右側方から覆う。本実施形態では、主壁部６０は、配線器具１を前方から覆う前壁６０１と、配線器具１を上方から覆う上壁６０２とを含んでいる。 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.
　ここにおいて、カバー本体６は、配線器具１の全体を覆うのではなく、配線器具１の一部分を覆うように構成されている。本実施形態では、カバー本体６は、配線器具１のうち少なくとも本体ユニット３が収納された収納部４２を、前方、上方、左側方及び右側方の四方から覆う形状に形成されている。言い換えれば、配線器具１にカバー本体６が取り付けられた状態であっても、配線器具１の後面及び収納部４２の下面についてはカバー本体６にて覆われず、カバー本体６から露出した状態となる。 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 this embodiment, the cover main body 6 is formed in a shape that covers the storage portion 42 in which at least the main body unit 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.
　さらに詳しく説明すると、カバー本体６は、後面及び下面が開放されており、上下方向に長い中空の直方体状に形成されている。本実施形態では、前壁６０１、上壁６０２、第１側壁６１及び第２側壁６２の厚みは、略同等の寸法である。前壁６０１は、前後方向に対して直交し、上下方向に長い矩形板状に形成されている。上壁６０２は、前壁６０１の上端縁から後方に突出するように構成されている。上壁６０２は、左右方向に長い矩形板状に形成されている。第１側壁６１は、前壁６０１の左端縁から後方に突出するように構成されている。第２側壁６２は、前壁６０１の右端縁から後方に突出するように構成されている。そして、上壁６０２の左端縁は第１側壁６１の上端縁と繋がっており、上壁６０２の右端縁は第２側壁６２の上端縁と繋がっている。 More specifically, the cover body 6 is formed in a hollow rectangular parallelepiped shape that is open at the rear and lower surfaces and 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.
　本実施形態では、前壁６０１と第１側壁６１との間の連結部分及び前壁６０１と第２側壁６２との間の連結部分は、いずれも第１の曲率半径で湾曲している。また、前壁６０１と上壁６０２との間の連結部分、上壁６０２と第１側壁６１との間の連結部分及び上壁６０２と第２側壁６２との間の連結部分は、いずれも第２の曲率半径で湾曲している。第１の曲率半径は第２の曲率半径よりも大きい。 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 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 the first. Curved with a radius of curvature of 2. The first radius of curvature is greater than the second radius of curvature.
　ここで、第１側壁６１及び第２側壁６２の各々は、前壁６０１に対して略直交する。つまり、第１側壁６１及び第２側壁６２の各々は、左右方向に対して略直交する。ただし、本開示で用いる「直交」は、厳密に９０度で交わる状態だけでなく、ある程度の誤差の範囲内で略直交する状態も含む意味である。一方、上壁６０２は、水平面に対して平行ではなく、斜め前方に向けてやや傾斜している。つまり、上壁６０２はやや前下がりになっており、カバー本体６の上面に雨水が溜まらない程度の勾配を付与している。 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.
　さらに、第１側壁６１及び第２側壁６２の各々の後端部は、収納部４２の下端縁よりも下方まで延長された形状に形成されている。これにより、カバー本体６の上下方向の寸法は、ボディ４の上下方向の寸法と略同等となり、配線器具装置１０を左右方向の側方から見たときの、ボディ４とカバー本体６との一体感が高められている。 Furthermore, the rear end portions of each of the first side wall 61 and the second side wall 62 are 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.
　ところで、カバー本体６は、光輝性顔料を含有する難燃性樹脂からなる。ここでいう「光輝性顔料」とは、例えば金属粉（金属フレーク）、雲母、酸化チタン又はガラスフレーク等からなり、金属性の光沢又はパールのような光沢を発揮する顔料である。本実施形態では、光輝性顔料として金属粉（一例としてアルミフレーク）を用い、カバー本体６を構成する難燃性樹脂にメタリック色の着色を施している。つまり、カバー本体６を構成する難燃性樹脂は、透光性樹脂からなる基材に光輝性顔料を含有することで成形前の原料段階で着色された、いわゆる原着（原料着色）樹脂である。この種の原着樹脂を用いることで、無塗装（塗装レス）であっても、完成品（カバー本体６）にメタリック色等の着色を実現可能である。難燃性樹脂の基材は、例えばポリカーボネートである。 By the way, 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.
　また、ここでいう「難燃性樹脂」とは、樹脂の燃焼性について、可燃性と難燃性（不燃性を含む）とに分類したときに、可燃性ではなく難燃性を有する樹脂である。本実施形態では、カバー本体６は、難燃性ＵＬ９４　Ｖ－２以上の難燃性を有する。「ＵＬ９４」とは、ＵＬ（Underwriters Laboratories）社によって定められた難燃性の評価の規格である。ＵＬ９４規格のグレードとしては、水平燃焼試験での「ＨＢ」、垂直燃焼試験での「Ｖ－２」、「Ｖ－１」、「Ｖ－０」、「５ＶＡ」、「５ＶＢ」の計６つのグレードがある。これら６つのグレードは、「ＨＢ」の難燃性が最も低く、「ＨＢ」、「Ｖ－２」、「Ｖ－１」、「Ｖ－０」、「５ＶＢ」、「５ＶＡ」の順に難燃性が高くなる。つまり、ＵＬ９４　Ｖ－２以上の難燃性を有するカバー本体６は、「ＨＢ」を除いて、「Ｖ－２」、「Ｖ－１」、「Ｖ－０」、「５ＶＢ」及び「５ＶＡ」のいずれかの難燃性を有することになる。ＵＬ９４　Ｖ－２以上の難燃性を有する樹脂は、大気中において、炎にさらされる間は燃えるが炎から離されれば消火する性質（自己消火性）を有する。言い換えれば、カバー本体６の材料となる難燃性樹脂は、試料の厚みが例えば２．５ｍｍである場合のＵＬ９４規格において「Ｖ－２」以上の難燃性を有することが好ましい。 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 body 6 has a flame retardancy of flame retardancy UL94 V-2 or higher. “UL94” is a standard for evaluation of flame retardancy determined 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 6 grades have the lowest flame retardancy of “HB”, “HB”, “V-2”, “V-1”, “V-0”, “5VB”, “5VA” in this order. Increases nature. In other words, the cover body 6 having flame retardancy of UL94 V-2 or higher is “V-2”, “V-1”, “V-0”, “5VB” and “5VA” except for “HB”. It will have any flame retardancy. UL94 V-2 or more flame retardant resin has the property of self-extinguishing in the atmosphere when it is exposed to flame, but extinguishes when released 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.
　ここにおいて、前壁６０１の前面６０３における左右方向の中央部には、ラベル部材７を貼り付けるための貼付部６０４が形成されている。貼付部６０４は、前壁６０１の前面６０３における左右方向の両端部に比べて、僅かに窪んでいる。貼付部６０４は、前壁６０１の上下方向の略全長に亘って形成されている。貼付部６０４の略中心には、ゲート跡６６が位置する。言い換えれば、主壁部６０のうち前壁６０１における配線器具１とは反対側の一表面（前面６０３）には、ゲート跡６６が設けられている。詳しくは「（３）配線器具用カバーの製造方法」の欄で説明するが、ゲート跡６６は、カバー本体６の成形時において金型内に樹脂を流入する際の樹脂の入り口となる部分である。 Here, a pasting portion 604 for pasting 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. Details will be described in the section of “(3) Manufacturing method of cover for wiring device”, but the gate mark 66 is a portion serving as an entrance of the resin when the resin flows into the mold when the cover body 6 is molded. is there.
　また、カバー本体６のうち、少なくとも第１側壁６１及び第２側壁６２の各々における配線器具１とは反対側の一表面は、シボ加工（エンボス加工）された凹凸面からなる。ここでいう「シボ加工」は、カバー本体６の成形時において、カバー本体６の表面に細かい凹凸のしわ模様（シボ）を付ける加工である。本実施形態では、カバー本体６のうち、第１側壁６１の左側面（配線器具１とは反対側の一表面）が凹凸面６１１からなり、第２側壁６２の右側面（配線器具１とは反対側の一表面）が凹凸面６２１からなる。さらに、カバー本体６のうち、前壁６０１の前面６０３及び上壁６０２の上面についても、同様にシボ加工された凹凸面からなる。これにより、カバー本体６は、無塗装（塗装レス）であっても、表面の細かい凹凸によって塗装に類似する質感を実現可能である。ただし、前壁６０１の前面６０３のうち貼付部６０４については、ラベル部材７によって覆われるので、凹凸面である必要はない。 Further, at least one surface of the cover main body 6 on the opposite side 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 opposite to the wiring device 1) is composed of the uneven surface 611, and the right side surface of the second side wall 62 (what is the wiring device 1). The one surface on the opposite side is made up of an 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.
　また、カバー本体６は、配線器具１との結合用の構造として、図５に示すように第１リブ６３、第２リブ６４及び引掛爪６５を有している。第１リブ６３は、第１側壁６１及び第２側壁６２の各々における後端部の内側面から突出している。第２リブ６４は、上壁６０２の後端部の内側面から突出している。第１リブ６３及び第２リブ６４の各々は、カバー本体６の後面の開口の周縁に沿って延びた形状に形成されている。引掛爪６５は、前壁６０１の下端部の後面から突出している。 The cover body 6 has a first rib 63, a second rib 64, and a hooking claw 65 as a structure for coupling with the wiring device 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.
　ラベル部材７は、薄板状であって、カバー本体６の貼付部６０４に対して貼り付けられる。つまり、ラベル部材７は、ゲート跡６６を覆うように、主壁部６０のうち前壁６０１における一表面（前面６０３）に取り付けられる。ラベル部材７は、粘着剤又は粘着テープによって貼付部６０４に貼り付けられてもよいし、接着剤等で貼付部６０４に貼り付けられてもよい。ラベル部材７の材質は、樹脂、金属又は紙等である。 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.
　上述した構成により、カバー２は、配線器具１が施工面に取り付けられたままの状態で、配線器具１に対して着脱可能である。ここでは、カバー２は、ボディ４に対して前方から押し当てられた状態で下方にスライドさせられることにより、配線器具１に対して取り付けられる。このとき、第１リブ６３及び第２リブ６４が、ボディ４に形成された周溝４１４に嵌り込み、かつ引掛爪６５が収納部４２の下面の前端部に引っ掛かることによって、ボディ４に対してカバー２が結合される。一方、前壁６０１の後面と収納部４２の前面との隙間にドライバ等の治具を挿入して、引掛爪６５の引っ掛かりを解除した状態で、カバー２が上方にスライドさせられることにより、カバー２が配線器具１から取り外される。そのため、配線器具装置１０においては、配線器具１を施工面から取り外すことなく、カバー２のみ交換することが可能である。 With the configuration described above, 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. 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.
　（３）配線器具用カバーの製造方法
　次に、上述した構成のカバー２の製造方法について、図７を参照して説明する。図７では、金型９（ゲート部９０を含む）の一部の概略形状を想像線（２点鎖線）で示している。 (3) Manufacturing method of cover for wiring apparatus Next, the manufacturing method of the cover 2 of the structure mentioned above is demonstrated with reference to FIG. In FIG. 7, a schematic shape of a part of the mold 9 (including the gate portion 90) is indicated by an imaginary line (two-dot chain line).
　カバー２の製造方法は、カバー本体６を製造する工程として、少なくとも成形工程と、離型工程と、を有している。本実施形態では、カバー本体６は、射出成形によって成形される。 The method for manufacturing the cover 2 includes at least a molding process and a mold release process as processes for manufacturing the cover body 6. In the present embodiment, the cover body 6 is formed by injection molding.
　成形工程は、金型片９１，９２を含む複数の金型片を有する金型９を用いて、難燃性樹脂からなるカバー本体６を成形する工程である。この成形工程では、複数の金型片を組み合わせた状態で複数の金型片の間に生じる空洞内に、光輝性顔料を含有する難燃性樹脂を注入することで、難燃性樹脂からなるカバー本体６を成形する。離型工程は、成形工程後、複数の金型片をカバー本体６から離間させる工程である。 The molding step is a step of molding the cover body 6 made of a flame-retardant resin using the mold 9 having a plurality of mold pieces including the mold pieces 91 and 92. In this molding process, a flame retardant resin containing a glittering pigment is injected into a cavity generated between a plurality of mold pieces in a state where a plurality of mold pieces are combined, thereby comprising a flame retardant resin. The cover body 6 is molded. The mold release step is a step of separating the plurality of mold pieces from the cover body 6 after the molding step.
　ここで、成形工程においては、空洞のうちカバー本体６の主壁部６０に対応する位置にあるゲート部９０から、難燃性樹脂を注入する。本実施形態では、ゲート部９０は、主壁部６０の前面６０３における貼付部６０４の略中心に対応する位置に設けられている。そのため、成形されたカバー本体６においては、貼付部６０４の略中心に対応する位置に、ゲート跡６６が生じる。 Here, in the molding process, a flame retardant resin is injected from the gate portion 90 located at a position corresponding to the main wall portion 60 of the cover body 6 in the cavity. In the present embodiment, the gate portion 90 is provided at a position corresponding to the approximate center of the pasting portion 604 on the front surface 603 of the main wall portion 60. Therefore, in the molded cover body 6, a gate mark 66 is generated at a position corresponding to the approximate center of the pasting portion 604.
　ここにおいて、難燃性樹脂は、一般的に、可燃性樹脂に比べて流動性が低い。とくに、光輝性顔料を含有する難燃性樹脂においては、成形時に、例えばフローマーク及びウェルドライン等の成形不良を生じる可能性がある。本実施形態に係るカバー２の製造方法では、成形工程において、ゲート部９０をカバー本体６のうち主壁部６０に対応する位置に設けることで、主壁部６０から、隣接する第１側壁６１及び第２側壁６２への難燃性樹脂の流動状態を良くしている。これにより、カバー本体６の成形時に成形不良が生じにくくなる。 Here, the flame retardant resin is generally less fluid than the flammable resin. In particular, in a flame-retardant resin containing a luster pigment, molding defects such as flow marks and weld lines may occur during molding. In the manufacturing method of the cover 2 according to the present embodiment, in the molding step, the gate portion 90 is provided at a position corresponding to the main wall portion 60 in the cover body 6, so that the first side wall 61 adjacent from the main wall portion 60 is provided. And the flow state of the flame-retardant resin to the second side wall 62 is improved. Thereby, a molding defect becomes difficult to occur when the cover body 6 is molded.
　さらに、本実施形態に係るカバー２の製造方法では、複数の金型片９１，９２のうち、少なくとも第１金型片９１と、第２金型片９２との各々は、カバー本体６との対向面にシボ加工用の凹凸加工面を有している。第１金型片９１は、カバー本体６の第１側壁６１における配線器具１とは反対側の一表面（凹凸面６１１）に対向しており、カバー本体６との対向面に凹凸加工面９１１を有する。第２金型片９２は、カバー本体６の第２側壁６２における配線器具１とは反対側の一表面（凹凸面６２１）に対向しており、カバー本体６との対向面に凹凸加工面９２１を有する。そして、離型工程では、第１側壁６１及び第２側壁６２が対向する対向方向に沿って、第１金型片９１及び第２金型片９２の各々をカバー本体６から離間させる。つまり、離型工程において、第１金型片９１及び第２金型片９２を、凹凸面６１１，６２１に対して略直交する向き（図７に白抜き矢印で示す向き）に移動させることで、凹凸加工面９１１，９２１によって成形されたシボ（凹凸）が潰れにくくなる。 Furthermore, in the manufacturing method of the cover 2 according to the present embodiment, at least each of the first mold piece 91 and the second mold piece 92 among the plurality of mold pieces 91 and 92 is connected to the cover body 6. The opposing surface has a textured surface for embossing. The first mold piece 91 faces one surface (uneven surface 611) on the first side wall 61 of the cover body 6 opposite to the wiring device 1, and the uneven surface 911 faces the surface facing the cover body 6. Have The second mold piece 92 faces one surface (uneven surface 621) on the second side wall 62 of the cover body 6 opposite to the wiring device 1, and the uneven surface 921 faces the surface facing the cover body 6. Have In the mold release step, each of the first mold piece 91 and the second mold piece 92 is separated from the cover body 6 along the facing direction in which the first side wall 61 and the second side wall 62 face each other. That is, in the mold release step, the first mold piece 91 and the second mold piece 92 are moved in a direction substantially perpendicular to the concave and convex surfaces 611 and 621 (direction indicated by a white arrow in FIG. 7). The wrinkles (unevenness) formed by the uneven processed surfaces 911 and 921 are not easily crushed.
　さらに、金型９を構成する複数の金型片は、前壁６０１の前面６０３及び上壁６０２の上面との対向面にも、凹凸加工面を有している。そのため、前壁６０１の前面６０３及び上壁６０２の上面と対向する金型片についても、離型工程においては、前壁６０１の前面６０３及び上壁６０２の上面に対して略直交する向きに移動させることが好ましい。ただし、図７では、金型９を構成する複数の金型片のうち、前壁６０１の前面６０３及び上壁６０２の上面と対向する金型片の図示を省略している。 Furthermore, the plurality of mold pieces constituting the mold 9 have an uneven surface on the surface facing the front surface 603 of the front wall 601 and the upper surface of the upper wall 602. Therefore, the mold pieces facing the front surface 603 of the front wall 601 and the upper surface of the upper wall 602 also move in a direction substantially orthogonal to the upper surface of the front surface 603 of the front wall 601 and the upper wall 602 in the mold release process. It is preferable to make it. However, in FIG. 7, of the plurality of mold pieces constituting the mold 9, the illustration of the mold pieces facing the front surface 603 of the front wall 601 and the upper surface of the upper wall 602 is omitted.
　カバー本体６の製造時におけるカバー本体６の向きは、配線器具装置１０の使用方向に関係ない。そのため、配線器具装置１０の使用方向と同じ向きでカバー本体６が成形されてもよいし、例えば、前壁６０１が水平面に平行となる向きでカバー本体６が成形されてもよい。 The orientation of the cover body 6 at the time of manufacturing the cover body 6 is not related to the direction of use of the wiring device device 10. Therefore, the cover main body 6 may be molded in the same direction as the usage direction of the wiring device apparatus 10, or, for example, the cover main body 6 may be molded in a direction in which the front wall 601 is parallel to the horizontal plane.
　上述したような成形工程及び離型工程によって形成されたカバー本体６に対して、ゲート跡６６を覆い隠すように、貼付部６０４にラベル部材７が貼り付けられることにより、カバー２が完成する。 The cover 2 is completed by sticking the label member 7 to the sticking portion 604 so as to cover the gate mark 66 with respect to the cover main body 6 formed by the molding process and the releasing process as described above.

Are preferably provided with a textured surface 911 (or 921) for embossing on the surface facing the cover body 6. The first mold piece 91 faces one surface (uneven surface 611) on the first side wall 61 of the cover body 6 on the side opposite to the wiring device 1. The second mold piece 92 faces one surface (uneven surface 621) on the second side wall 62 of the cover body 6 on the opposite side to the wiring device 1. In this case, in the mold release step, each of the first mold piece 91 and the second mold piece 92 is separated from the cover body 6 along the facing direction in which the first side wall 61 and the second side wall 62 face each other. preferable. According to this manufacturing method, at least the first mold piece 91 and the second mold piece 92 move in a direction intersecting with the concavo- convex surfaces 611 and 621. (Unevenness) is not easily crushed. In particular, in the configuration in which the first side wall 61 and the second side wall 62 are substantially orthogonal to the front wall 601, the first mold piece 91 and the second mold piece 92 are substantially orthogonal to the concave and convex surfaces 611 and 621. Therefore, the formed wrinkles (unevenness) are less likely to be crushed. However, this configuration is not an essential configuration for the manufacturing method of the cover 2, and the uneven surfaces 611 and 621 may not be formed by the uneven processed surfaces 911 and 921.
