Description

本発明は、壁に埋設されて使用されるコンセントに関するものである。 The present invention relates to an outlet used by being embedded in a wall.

従来、この種のコンセントは種々市販されまた提案されている。例えば、特許文献１には、規格化された埋込ボックスに取付可能な寸法に形成された略箱形のボディ、このボディよりも大きい寸法に形成され開口面側からボディと結合されるカバーより成る器体と、カバーの前面に設けられ、形状が異なる複数種のプラグ端子（接触子）が挿入される２個の端子挿入孔（接触子挿入口）から成るコンセント口と、カバーの前面に設けられ、接地極を含む３つのプラグ端子が各々挿入される３個の端子挿入孔から成る３極型のコンセント口と、器体内に納装され埋込ボックスに配設された電線と接続される端子部と、器体内に挿入され、各コンセント口の端子挿入孔から挿入されるプラグ端子と接触導通するとともに端子部と電気的に接続される端子受け部（接触子受け部）とを備えたコンセントが開示されている。 Conventionally, various outlets of this type are commercially available and proposed. For example, Patent Document 1 discloses a substantially box-shaped body formed in a size that can be attached to a standardized embedding box, and a cover that is formed in a size larger than the body and is coupled to the body from the opening surface side. A receptacle body that is provided on the front surface of the cover, and that has two terminal insertion holes (contactor insertion ports) into which a plurality of types of plug terminals (contactors) of different shapes are inserted, and a front surface of the cover It is connected to a three-pole outlet port composed of three terminal insertion holes into which three plug terminals each including a grounding electrode are inserted, and an electric wire placed in the container and disposed in the embedded box. And a terminal receiving part (contact receiving part) electrically connected to the terminal part and electrically connected to the plug terminal inserted from the terminal insertion hole of each outlet port. Outlets are disclosed There.

そして、このコンセントは、コンセント口の各端子挿入孔を開閉自在に閉塞する扉をさらに備え、未使用時に扉で各端子挿入孔を閉塞することにより、各端子受け部の露出がないように構成されている。 The outlet further includes a door that can be freely opened and closed for each terminal insertion hole of the outlet port, and is configured so that each terminal receiving portion is not exposed by closing each terminal insertion hole with the door when not in use. Has been.

図１１は、上記と同様の扉を備える別のコンセントの外観図であり、（ａ），（ｂ）は扉で各端子挿入孔を閉めた状態を示す図、（ｃ），（ｄ）は各端子挿入孔に対し扉を開けた状態を示す図、図１２は同コンセントに使用される扉の正面図（ａ）、背面図（ｂ）、左側面図（ｃ）、下側面図（ｄ）および断面図（ｅ）である（例えば特許文献２など）。 FIG. 11 is an external view of another outlet provided with a door similar to the above, (a) and (b) are diagrams showing a state in which each terminal insertion hole is closed by the door, and (c) and (d) are The figure which shows the state which opened the door with respect to each terminal insertion hole, FIG. 12 is the front view (a), back view (b), left view (c), lower side view (d) of the door used for the outlet. ) And a sectional view (e) (for example, Patent Document 2).

この別のコンセントには、図１１，図１２に示すように、カバー２における一の接地極側の端子挿入孔２０ａおよび一対の電圧極側の端子挿入孔２０ｂ，２０ｂをそれぞれ閉塞するための一の接地極側の閉塞部６１および一対の電圧極側の閉塞部６２，６２を一体に有する枠状に形成された扉６がカバー２の背面側に設けられている。 As shown in FIG. 11 and FIG. 12, the other outlet is a plug for closing one ground electrode side terminal insertion hole 20a and a pair of voltage electrode side terminal insertion holes 20b, 20b in the cover 2, respectively. A door 6 formed in a frame shape integrally including a closing portion 61 on the ground electrode side and a pair of closing portions 62 and 62 on the voltage electrode side is provided on the back side of the cover 2.

このように構成されるコンセントでは、プラグの接地極側のプラグ端子を扉６の閉塞部６１における傾斜面６１ａに押し当てることにより、扉６を上側にスライドさせて、プラグの接地極側のプラグ端子、一対の電圧極側のプラグ端子をそれぞれ接地極側の端子受け部、一対の電圧極側の端子受け部に接続することができる。また、コンセントからプラグを抜いた場合には、扉６で端子挿入孔２０ａ，２０ｂ，２０ｂを閉塞することができる。

ところで、ＩＥＣやＧＢ規格には、扉に対し、φ１ｍｍのテストピンにより１Ｎで任意の３方向に負荷をかけたり、断面が１×３ｍｍのテストピンにより２０Ｎで連続した任意の３方向に負荷をかけたりする扉の性能試験があるが、コンセントの部品寸法ばらつきの許容範囲を拡げると、上記性能試験をクリアすることができないおそれが発生しうる。 By the way, in the IEC and GB standards, a load is applied to the door in any three directions at 1N with a φ1 mm test pin, or in any three directions that are continuous at 20 N with a test pin having a cross section of 1 × 3 mm. There is a door performance test, but there is a possibility that the performance test may not be cleared if the allowable range of variation in the size of the outlet parts is expanded.

図１３（ａ）に示すように、扉６が端子挿入孔２０ｂを正常に閉塞している状態ではなく、例えば、プラグの挿抜によるプラグ端子や端子受け部３１の削れた金属粉などが、異物となって、扉６とカバー２のリブ２０４との間に挟まったとすれば、図１３（ｂ）に示すように、テストピンＴＰが上記異物による隙間から端子受け部３１側に侵入しやすくなる。 As shown in FIG. 13 (a), the door 6 is not in a state of normally closing the terminal insertion hole 20b. If it is sandwiched between the door 6 and the rib 204 of the cover 2, the test pin TP is likely to enter the terminal receiving portion 31 side through the gap due to the foreign matter as shown in FIG. .

また、図１３（ｃ）に示すように、テストピンＴＰで扉６を押し開けて、テストピンＴＰを想像線の角度に倒したり、図１４に示すように、テストピンＴＰ２０を扉６に押し付けて矢印の方向に動かしたした場合にも、図１５に示すように隙間ができることにより、テストピンＴＰが端子受け部３１側に侵入しやすくなる。この問題は、扉６を閉める方向に付勢するコイルスプリングのばね圧を高くすれば解決可能となるが、プラグの挿入性が低下する別の問題が発生する。 Further, as shown in FIG. 13 (c), the door 6 is pushed open with the test pin TP, and the test pin TP is tilted to an imaginary line angle, or the test pin TP20 is pressed against the door 6 as shown in FIG. Even when it is moved in the direction of the arrow, the test pin TP can easily enter the terminal receiving portion 31 side by forming a gap as shown in FIG. This problem can be solved by increasing the spring pressure of the coil spring that urges the door 6 in the closing direction, but another problem that the plug insertion performance is lowered occurs.

本発明は、上記事情に鑑みてなされたものであり、テストピンで扉をこじ開けようとしても、扉を閉める方向に付勢する力を増強することなく、扉で内部を保護することができるコンセントを提供することを目的とする。 The present invention has been made in view of the above circumstances, and an outlet that can protect the inside with a door without increasing the force that biases the door in the closing direction, even if the door is opened with a test pin. The purpose is to provide.

本発明のコンセントは、正面に開口を有する箱状に形成され、一の接地極側電線の導体線を挿入するための一の接地極側電線挿入孔および一対の電圧極側電線の導体線をそれぞれ挿入するための一対の電圧極側電線挿入孔を少なくとも一組、底部となる背面部に有するボディと、このボディの開口を閉塞する形状に形成され、一の接地極側プラグ端子を挿入するための一の接地極側端子挿入孔および一対の電圧極側プラグ端子をそれぞれ挿入するための一対の電圧極側端子挿入孔を少なくとも一組、正面部に有するカバーと、前記ボディ内における前記接地極側端子挿入孔の背面側に設けられ、その接地極側端子挿入孔に挿入された接地極側プラグ端子と電気的に接続される接地極側端子受け部と、前記ボディ内における前記接地極側電線挿入孔の正面側に設けられ、その接地極側電線挿入孔に挿入された接地極側電線の導体線と電気的に接続されるとともに、前記接地極側端子受け部と電気的に接続される接地極側端子部と、前記ボディ内における前記一対の電圧極側端子挿入孔の背面側にそれぞれ設けられ、それら一対の電圧極側端子挿入孔に挿入された一対の電圧極側プラグ端子とそれぞれ電気的に接続される一対の電圧極側端子受け部と、前記ボディ内における前記一対の電圧極側電線挿入孔の正面側にそれぞれ設けられ、それら一対の電圧極側電線挿入孔に挿入された一対の電圧極側電線の導体線とそれぞれ電気的に接続されるとともに、前記一対の電圧極側端子受け部とそれぞれ電気的に接続される一対の電圧極側端子部と、前記接地極側端子挿入孔および前記一対の電圧極側端子挿入孔をそれぞれ閉塞するための一の接地極側閉塞部および一対の電圧極側閉塞部を一体に有する形状に形成され、前記カバーと前記接地極側端子受け部および前記一対の電圧極側端子受け部との間に介設される扉と、この扉を、前記カバーの正面部の内面に沿ってスライド自在に、前記接地極側端子挿入孔および前記一対の電圧極側端子挿入孔を閉塞する方向に付勢する付勢手段とを備え、前記電圧極側閉塞部は、閉塞するべき前記電圧極側端子挿入孔よりも大きい寸法に設定されており、当該電圧極側端子挿入孔を閉塞している場合に当該電圧極側端子挿入孔と対向する面に、少なくとも当該電圧極側端子挿入孔と同じ寸法に設定された凹部を有していることを特徴とする。 The outlet of the present invention is formed in a box shape having an opening on the front, and includes one grounding electrode side electric wire insertion hole and a pair of voltage electrode side electric wire conductors for inserting the conductor wire of one grounding electrode side electric wire. A body having at least one pair of voltage electrode-side electric wire insertion holes for insertion, respectively, on the back surface serving as the bottom, and a shape that closes the opening of the body, and inserting one ground electrode-side plug terminal A cover having at least one pair of voltage electrode side terminal insertion holes for inserting one ground electrode side terminal insertion hole and a pair of voltage electrode side plug terminals for the front part, and the grounding in the body A ground electrode side terminal receiving portion provided on the back side of the electrode side terminal insertion hole and electrically connected to the ground electrode side plug terminal inserted into the ground electrode side terminal insertion hole; and the ground electrode in the body Side wire insertion Grounding provided on the front side of the hole and electrically connected to the conductor wire of the grounding electrode side electric wire inserted into the earthing electrode side electric wire insertion hole and electrically connected to the grounding electrode side terminal receiving portion An electric terminal and a pair of voltage electrode side plug terminals respectively provided on the back side of the pair of voltage electrode side terminal insertion holes in the body and inserted into the pair of voltage electrode side terminal insertion holes A pair of voltage electrode side terminal receiving portions connected to each other and a pair of voltage electrode side wire insertion holes provided in front of the pair of voltage electrode side wire insertion holes in the body, respectively. A pair of voltage electrode terminals connected to the conductors of the voltage electrode wires and a pair of voltage electrode terminals receiving the pair of voltage electrode terminals, and inserting the ground electrode terminals Hole and said pair The cover, the ground electrode side terminal receiving portion, and the pair of voltage electrode side block portions are formed integrally with a ground electrode side block portion and a pair of voltage electrode side block portions. A door interposed between the voltage electrode side terminal receiving portion and the door, and the door is slidable along the inner surface of the front portion of the cover, so that the ground electrode side terminal insertion hole and the pair of voltage electrode side terminals Biasing means for biasing in the direction of closing the insertion hole, and the voltage electrode side closing portion is set to a size larger than the voltage electrode side terminal insertion hole to be closed, and the voltage electrode side terminal When the insertion hole is closed, the surface facing the voltage electrode side terminal insertion hole has at least a concave portion set to the same size as the voltage electrode side terminal insertion hole.

本発明によれば、扉をテストピンで押し開いた状態でそのテストピンを傾けても、テストピンを凹部によってこの底側に誘い込むことができる。別言すると、テストピンを電圧極側端子受け部側に入り込ませるには、テストピンが凹部周縁の段差を乗り越えるようにそのテストピンを操作しなければならないので、段差を乗り越えさせる必要のない従来の平板状の扉に比べて、テストピンを電圧極側端子受け部側に入り込ませ難くすることができる。これにより、テストピンで扉をこじ開けようとしても、付勢手段により扉を閉める方向に付勢する力を増強することなく、扉で内部を保護することができる。 According to the present invention, even if the test pin is tilted in a state where the door is pushed open by the test pin, the test pin can be guided to the bottom side by the recess. In other words, in order for the test pin to enter the voltage electrode terminal receiving part side, the test pin has to be operated so that it goes over the step at the periphery of the recess, so there is no need to go over the step. Compared to the flat door, the test pin can be made difficult to enter the voltage electrode terminal receiving portion side. Thereby, even if it tries to pry open a door with a test pin, an inside can be protected with a door, without strengthening the force biased in the direction which closes a door by a biasing means.

本実施形態では、左右一組の組立枠８が、いわゆる１個モジュール寸法の配線器具を取付枠に取り付ける役割を担うようになっており、ボディ１およびカバー２により構成される２個モジュール寸法の器体に対して二組４個使用されるようになっている。 In the present embodiment, a pair of left and right assembly frames 8 plays a role of attaching a so-called single module-sized wiring device to the mounting frame, and has a two-module size constituted by the body 1 and the cover 2. Two sets of four are used for the body.

次に、上記構成のコンセントの組立手順例について説明する。まず、ボディ１の収納室１０ａ内における治具挿通孔の正面側の所定位置に解除釦３２３を収納し、各接地極側電線挿入孔の正面側の所定位置に各鎖状ばね３２２を収納するとともに、ボディ１の各収納室１０ｂ内における治具挿通孔の正面側の所定位置に解除釦４２３を収納し、電圧極側電線挿入孔の正面側の所定位置に各鎖状ばね４２２を収納する。 Next, an example of an assembly procedure of the outlet having the above configuration will be described. First, the release button 323 is stored in a predetermined position on the front side of the jig insertion hole in the storage chamber 10a of the body 1, and each chain spring 322 is stored in a predetermined position on the front side of each grounding electrode side electric wire insertion hole. At the same time, the release button 423 is stored in a predetermined position on the front side of the jig insertion hole in each storage chamber 10b of the body 1, and each chain spring 422 is stored in a predetermined position on the front side of the voltage electrode side electric wire insertion hole. .

続いて、端子受け部３１および端子板３２１の一体部品を、それぞれを下および上にして収納室１０ａ内に収納するとともに、端子受け部４１および端子板４２１の各一体部品を、互いに隣接する収納室１０ｃおよび収納室１０ｂ内に収納する。 Subsequently, the integrated parts of the terminal receiving part 31 and the terminal plate 321 are stored in the storage chamber 10a with the respective parts downward and upward, and the integrated parts of the terminal receiving part 41 and the terminal plate 421 are stored adjacent to each other. It accommodates in the chamber 10c and the storage chamber 10b.

続いて、端子受け部３１，４１，４１にそれぞれ中枠５の窓孔５ａ，５ｂ，５ｂの位置を合わせながら、端子受け部３１の正面側先端部を窓孔５ａ内に入れて、中枠５をボディ１の正面側に載置する。 Subsequently, while aligning the positions of the window holes 5a, 5b, 5b of the middle frame 5 with the terminal receiving portions 31, 41, 41, respectively, the front end portion on the front side of the terminal receiving portion 31 is placed in the window hole 5a, 5 is placed on the front side of the body 1.

続いて、カバー２のリブ２０１内に扉６の閉塞部６１を填め込むとともに、カバー２のリブ２０３，２０３間に扉６の突起６３を填め込んで、カバー２のリブ２０１，２０２，２０２，２０３，２０３の端面上に扉６を載置する。この後、扉６の矩形孔６ａからカバー２のリブ２０３，２０３間にコイルスプリング７を収納する。 Subsequently, the closing portion 61 of the door 6 is fitted into the rib 201 of the cover 2, and the protrusion 63 of the door 6 is fitted between the ribs 203, 203 of the cover 2, so that the ribs 201, 202, 202, The door 6 is placed on the end surfaces of 203 and 203. Thereafter, the coil spring 7 is accommodated between the rectangular holes 6 a of the door 6 and the ribs 203 of the cover 2.

続いて、ボディ１およびカバー２の各開口縁部同士を合わせて、４つの組立枠８を用いて、ボディ１およびカバー２を固定する。これにより、コンセントの組立が完了する。そして、組立が完了したコンセントを従来と同様にして壁に埋設した後、図１０に示すように、プラグＰのプラグ端子Ｐ２，Ｐ２よりも長いプラグ端子Ｐ１を扉６の閉塞部６１における傾斜面６１ａに押し当てることにより、扉６を上側にスライドさせて、プラグ端子Ｐ１，Ｐ２，Ｐ２をそれぞれ端子受け部３１，４１，４１に接続することになる。 Subsequently, the opening edges of the body 1 and the cover 2 are aligned with each other, and the body 1 and the cover 2 are fixed using the four assembly frames 8. Thereby, the assembly of the outlet is completed. Then, after the assembled outlet is embedded in the wall in the same manner as in the prior art, the plug terminal P1 longer than the plug terminals P2 and P2 of the plug P is inclined on the closed surface 61 of the door 6 as shown in FIG. By pressing against 61a, the door 6 is slid upward to connect the plug terminals P1, P2, P2 to the terminal receiving portions 31, 41, 41, respectively.

本実施形態では、第１の特徴により、扉６とカバー２のリブ２０４との間に微小な異物が挟まっても、図９（ｂ）に示すように、扉６とカバー２のリブ２０２との間の隙間が狭くなるので、端子受け部４１側へのテストピンＴＰの侵入を防ぐことができる。 In the present embodiment, due to the first feature, even if a minute foreign matter is sandwiched between the door 6 and the rib 204 of the cover 2, as shown in FIG. Since the gap between them becomes narrow, it is possible to prevent the test pin TP from entering the terminal receiving portion 41 side.

また、第２の特徴により、図９（ｃ）に示すように、扉６をテストピンＴＰで押し開いた状態でそのテストピンＴＰを傾けても、テストピンＴＰを凹部６２０によってこの底側に誘い込むことができる。別言すると、テストピンＴＰを端子受け部４１側に入り込ませるには、テストピンＴＰが凹部６２０の段差を乗り越えるようにそのテストピンＴＰを操作しなければならないので、図１３（ｃ）のように段差を乗り越えさせる必要のない従来に比べて、テストピンＴＰを端子受け部４１側に入り込ませ難くすることができる。これにより、テストピンＴＰで扉６をこじ開けようとしても、コイルスプリング７により扉６を閉める方向に付勢する力を増強することなく、扉６で内部を保護することができる。また、テストピンＴＰを引けば、コイルスプリング７で付勢された扉６によって端子挿入孔２０ｂを閉塞することができるので、テストピンＴＰを端子受け部４１側に侵入させることができないようにすることができる。 Further, according to the second feature, as shown in FIG. 9C, even if the test pin TP is tilted in a state where the door 6 is pushed open by the test pin TP, the test pin TP is brought to the bottom side by the recess 620. I can invite you. In other words, in order for the test pin TP to enter the terminal receiving portion 41 side, the test pin TP must be operated so that the test pin TP gets over the step of the recess 620, as shown in FIG. Compared to the conventional case where it is not necessary to overcome the step, the test pin TP can be made difficult to enter the terminal receiving portion 41 side. Thereby, even if it tries to pry open the door 6 with the test pin TP, the inside can be protected by the door 6 without increasing the force for urging the door 6 in the closing direction by the coil spring 7. Also, if the test pin TP is pulled, the terminal insertion hole 20b can be closed by the door 6 biased by the coil spring 7, so that the test pin TP cannot be allowed to enter the terminal receiving portion 41 side. be able to.
