In addition, the outlet shown in FIG. 15 includes two outlets having different shapes in one container 1. That is, the outlet shown in FIG. 15 is provided with an outlet port including two insertion ports 22b and 22b in addition to an outlet port including three insertion ports 21a, 21b and 21c. Blade receiving springs 14e 'and 14e' are housed in portions corresponding to the insertion ports 22b and 22b, respectively. More specifically, blade receiving springs 14a 'and 14b' and terminals 14c 'and 14c' for connecting external wires to the voltage pole sections 12b and 12c in the body 10 of the outlet shown in FIG.

ところで、図12(a)に示したコンセントと図12(b)に示したコンセントとでは、定格の違い(定格電流の違い)に応じて、規定方向(図12では左右方向)に並設されている差込口21b,21cの間隔が異なり、対応する刃受ばね14a’,14b’、14a”,14b”間の間隔も異なっており、定格に合わせてそれぞれ専用の部品が必要なので、コストが高くなってしまう。なお、図13および図14に示したコンセントでは、カバー20の内底面から突設した押さえリブ25cが接続片13c’に当接することによりボディ10からの刃受ばね13a’の浮き上がりを防止することができるが、接続片13c’は刃受ばね13a’の一対のばね片の後端縁同士を連続一体に連結する連結片の側縁から側方へ延設されたものであるから、カバー20の内底面と接続片13c’との間の距離が比較的大きく、カバー20の内底面からの押さえリブ25cの突出寸法を大きくする必要があり、押さえリブ25cの機械的な強度が弱くなってしまうことがある。また、図15に示したコンセントでは、上述のリード板14h’,14iと刃受ばね14e’,14e’とを別部品としてかしめ固定により結合しているので、左右の刃受ばね14e’,14e’を共通部品とすることができるが、リード板14h’,14i’については左右で形状が異なっているので、それぞれ専用の部品を用意する必要がある。また、リード板14h’,14i’と刃受ばね14e’,14e’とを別体としているので、部品点数が多くなり、コストが高くなる。   Incidentally, the outlet shown in FIG. 12 (a) and the outlet shown in FIG. 12 (b) are juxtaposed in a specified direction (left and right in FIG. 12) according to the difference in rating (difference in rated current). The intervals between the insertion ports 21b and 21c are different, the intervals between the corresponding blade receiving springs 14a ', 14b', 14a ", 14b" are also different, and dedicated parts are required according to the rating. Becomes higher. In the outlet shown in FIGS. 13 and 14, the pressing rib 25 c protruding from the inner bottom surface of the cover 20 abuts on the connection piece 13 c ′ to prevent the blade receiving spring 13 a ′ from lifting from the body 10. However, since the connecting piece 13c ′ is extended from the side edge of the connecting piece that continuously connects the rear end edges of the pair of spring pieces of the blade receiving spring 13a ′ to the side, the cover 20 The distance between the inner bottom surface and the connecting piece 13c ′ is relatively large, and it is necessary to increase the protruding dimension of the pressing rib 25c from the inner bottom surface of the cover 20, so that the mechanical strength of the pressing rib 25c is weakened. It may end up. Further, in the outlet shown in FIG. 15, the above-described lead plates 14h ′ and 14i and the blade receiving springs 14e ′ and 14e ′ are combined as separate parts by caulking and fixed, so that the left and right blade receiving springs 14e ′ and 14e. 'Can be a common component, but the lead plates 14h' and 14i 'have different shapes on the left and right sides, and it is necessary to prepare dedicated components for each. Further, since the lead plates 14h 'and 14i' and the blade receiving springs 14e 'and 14e' are separated, the number of parts is increased and the cost is increased.

本発明は上記事由に鑑みて為されたものであり、その目的は、定格の違いに応じて規定方向の差込口の間隔が異なる他のコンセントと刃受ばねの共通化を図り低コスト化を図れるコンセントを提供することにある。   The present invention has been made in view of the above-mentioned reasons, and its purpose is to reduce the cost by using the blade receiving spring in common with other outlets in which the interval of the insertion port in the specified direction differs depending on the rating.

図2に示すように、ボディ10の上下両端部(図2の右上方を上とする)にはそれぞれ前方に向かって組立片10aが2枚ずつ突設され、各組立片10aには組立凹所として機能する組立孔10bがそれぞれ形成される。一方、カバー20の上下両側面には組立片10aに設けた組立孔10bに凹凸係合する組立凸部として機能する組立突起20aが2個ずつ突設される。組立突起20aは後面が傾斜面であって、組立片10aと組立突起20aとを位置合わせし、ボディ10とカバー20とを互いに押し付けると、組立突起20aに押されて組立片10aが撓み、その後、組立突起20aが組立孔10bに嵌入する。このように、組立時にはボディ10とカバー20とを互いに押し付けるだけの簡単な作業でボディ10とカバー20とを結合することができる。   As shown in FIG. 2, two assembly pieces 10a project from the upper and lower ends of the body 10 (the upper right side in FIG. 2 is the upper side), respectively, and each assembly piece 10a has an assembly recess. Assembly holes 10b functioning as places are formed. On the other hand, two assembly protrusions 20a functioning as assembly protrusions that engage with the assembly holes 10b provided in the assembly piece 10a are projected on both upper and lower side surfaces of the cover 20 each. The rear surface of the assembly protrusion 20a is an inclined surface. When the assembly piece 10a and the assembly protrusion 20a are aligned and the body 10 and the cover 20 are pressed against each other, the assembly protrusion 10a is pushed and the assembly piece 10a is bent. The assembly protrusion 20a is inserted into the assembly hole 10b. As described above, the body 10 and the cover 20 can be coupled by a simple operation of pressing the body 10 and the cover 20 together at the time of assembly.

ボディ10の内部は、仕切壁11によって3室に仕切られている。すなわち、ボディ10の内部には、中央部に設けた接地極用区画12aと、ボディ10の幅方向の両側部において長手方向の略全長に亘って設けられる2個の電圧極用区画12b,12cとが設けられる。接地極用区画12aには接地極用部材13が収納され、電圧極用区画12b,12cには電圧極用部材14,14が収納される。   The interior of the body 10 is partitioned into three chambers by a partition wall 11. That is, in the body 10, a grounding electrode section 12 a provided in the center portion and two voltage electrode sections 12 b and 12 c provided over substantially the entire length in the longitudinal direction on both sides in the width direction of the body 10. And are provided. A ground electrode member 13 is stored in the ground electrode section 12a, and voltage electrode members 14 and 14 are stored in the voltage electrode sections 12b and 12c.

接地極用部材13は、短冊状に形成された平栓刃を受ける刃受ばね13aと、刃受ばね13aとボディ10の後壁に開口する電線挿入口15から導入される外部電線を接続するための端子13bとをかしめピンにより一体に結合したものであって、平栓刃をボディ10の幅方向の中央部で受けるように接地極用区画12aに収納される。また、接地極用区画12bに収納される電圧極用部材14は、平栓刃を受ける刃受ばね14aと、ボディ10の後壁に開口する電線挿入口15から導入される外部電線を接続するための端子14c,とを一体に結合したものであり、接地極用区画12cに収納される電圧極用部材14は、平栓刃を受ける刃受ばね14aと、後述の導電板51とを一体に結合したものであり、接地極用区画12bには端子14cなども収納される。なお、刃受けばね14a,14bは図3(a)の下部に位置させる形で各電圧極用区画12b,12cにそれぞれ収納される。   The grounding electrode member 13 connects a blade receiving spring 13a that receives a flat plug blade formed in a strip shape, and an external electric wire introduced from the blade receiving spring 13a and an electric wire insertion port 15 that opens in the rear wall of the body 10. The terminal 13b is integrally coupled with the caulking pin, and is accommodated in the ground electrode section 12a so that the flat plug blade is received at the center in the width direction of the body 10. The voltage electrode member 14 housed in the ground electrode section 12b connects a blade receiving spring 14a that receives a flat plug blade and an external electric wire introduced from an electric wire insertion port 15 that opens in the rear wall of the body 10. The voltage electrode member 14 housed in the grounding electrode section 12c is integrally formed with a blade receiving spring 14a for receiving a flat plug blade and a conductive plate 51 to be described later. The terminal 14c is also accommodated in the ground electrode section 12b. The blade receiving springs 14a and 14b are housed in the voltage electrode sections 12b and 12c, respectively, so as to be positioned at the lower part of FIG.

刃受ばね13a,14a,14bは平栓刃を受けるものであるから、板ばねからなる2枚のばね片を対向させた形で配置し、両ばね片の間に平栓刃を挟持する。刃受ばね13a,14a,14bについては後述する。   Since the blade receiving springs 13a, 14a and 14b receive flat plug blades, two spring pieces made of leaf springs are arranged to face each other, and the flat plug blade is sandwiched between the two spring pieces. The blade receiving springs 13a, 14a, and 14b will be described later.

端子13b,14c,14cは、電線挿入口15を通して器体1の内部に導入された外部電線を板ばねのばね力を用いて鎖錠する速結端子であって、長方形状の基片16aの幅方向の一側縁からU字状の鎖錠片16bを2枚延設し、基片16aの幅方向の他側縁から各鎖錠片16bの先端側の脚片に対向するように押さえ片16cを2枚延設した構成を有する。鎖錠片16bの先端側の脚片は鎖錠片16bの基片16a側の脚片と押さえ片16cとの間に位置する。端子13b,14c,14cは、電線挿入口15を通して導入される外部電線が押さえ片16cの先端側から鎖錠片16bと押さえ片16cとの間に導入されるように配置される。鎖錠片16bの先端部は、先端に近い部位ほど押さえ片16c寄りに傾斜し、押さえ片16cには鎖錠片16bの先端と電線挿入口15との間である中間部において、鎖錠片16bに向かって凸となる形状に屈曲した部位が形成される。したがって、電線挿入口15を通して器体1の内部に導入された外部電線は、鎖錠片16bと押さえ片16cとの間で挟持されることにより端子13b,14cに電気的に接続され、さらに鎖錠片16bの先端縁が外部電線に食い込む鎖錠状態となって抜け止めがなされる。上述したように1枚の基片16aには鎖錠片16bと押さえ片16cとを2枚ずつ設けているから、それぞれ2本の外部電線を接続することができる。ボディ10を透明合成樹脂の成形品とすれば、電線挿入口15から器体1に挿入された電線が端子13b,14c,14cに適正に接続されているか否かを視認することが可能になり、結線作業の作業性が向上する。   The terminals 13b, 14c, and 14c are quick connection terminals that lock the external electric wires introduced into the body 1 through the electric wire insertion port 15 by using the spring force of the leaf springs. Two U-shaped locking pieces 16b are extended from one side edge in the width direction and pressed so as to face the leg pieces on the distal end side of each locking piece 16b from the other side edge in the width direction of the base piece 16a. It has a configuration in which two pieces 16c are extended. The leg piece on the distal end side of the locking piece 16b is located between the leg piece on the base piece 16a side of the locking piece 16b and the pressing piece 16c. The terminals 13b, 14c, and 14c are arranged such that an external electric wire introduced through the electric wire insertion port 15 is introduced between the locking piece 16b and the holding piece 16c from the distal end side of the holding piece 16c. The distal end portion of the locking piece 16b is inclined closer to the pressing piece 16c as the portion is closer to the distal end, and the holding piece 16c has a locking piece at an intermediate portion between the distal end of the locking piece 16b and the wire insertion port 15. A portion bent into a shape that protrudes toward 16b is formed. Therefore, the external electric wire introduced into the body 1 through the electric wire insertion port 15 is electrically connected to the terminals 13b and 14c by being sandwiched between the locking piece 16b and the holding piece 16c, and further connected to the chain. The distal end edge of the lock piece 16b is locked to bite into the external electric wire, and is prevented from coming off. As described above, since one base piece 16a is provided with two locking pieces 16b and two holding pieces 16c, two external wires can be connected to each. If the body 10 is made of a transparent synthetic resin, it is possible to visually check whether or not the electric wire inserted into the container 1 from the electric wire insertion port 15 is properly connected to the terminals 13b, 14c, and 14c. The workability of the wiring work is improved.

各端子13b,14c,14cにおける2枚の鎖錠片16bの間の部位には解除レバー17が配置される。解除レバー17は、ボディ10における上下方向の中央部に形成した挿通用スリット10dを通して一端部がボディ10から露出するレバー本体17aを有し、レバー本体17aの他端部にはボディ10の内部で定位置に支承される軸部17bが形成され、さらに軸部17bの両側面には1個の端子13b,14c,14cにおける2枚の鎖錠片16bに当接可能な2個の押し部17cが形成されている。挿通用スリット10dはボディ10の前端縁において開放されている。外部電線を端子13b,14c,14cに接続した状態において、解除レバー17を軸部17bの回りに回転させると(例えば、図3(b)において右側の解除レバー17を反時計方向に回転させるように起こすと)、鎖錠片16bの先端部が押し部17cによって押さえ片16cから離れる向きの力を受け、外部電線の鎖錠状態が解除され外部電線を器体1から容易に引き抜くことができるようになる。   A release lever 17 is arranged at a portion between the two locking pieces 16b in each terminal 13b, 14c, 14c. The release lever 17 has a lever main body 17a having one end exposed from the body 10 through an insertion slit 10d formed in the center in the vertical direction of the body 10, and the other end of the lever main body 17a is provided inside the body 10. A shaft portion 17b supported at a fixed position is formed, and two push portions 17c capable of contacting the two locking pieces 16b of one terminal 13b, 14c, 14c are formed on both side surfaces of the shaft portion 17b. Is formed. The insertion slit 10 d is opened at the front edge of the body 10. When the release lever 17 is rotated around the shaft portion 17b in a state where the external electric wires are connected to the terminals 13b, 14c, and 14c (for example, the right release lever 17 is rotated counterclockwise in FIG. 3B). ), The distal end portion of the locking piece 16b receives a force in a direction away from the pressing piece 16c by the pushing portion 17c, the locked state of the external electric wire is released, and the external electric wire can be easily pulled out from the body 1. It becomes like this.

また、カバー20には、上述した各刃受ばね13a,14a,14bに対応する部位に、それぞれカバー20の表裏に貫通した差込口21a,21b,21cが形成されている。差込口21aは図3(a)の上下方向に長い長方形状に開口しており接地極となる平栓刃が挿入される。さらに、差込口21b,21cは、平栓刃が挿入されるように長方形状に開口しており、図3(a)において差込口21aの下方に位置するとともに左右方向に並設される。両差込口22aは、下端側の距離が上端側の距離よりも小さくなるように傾斜している。しかして、本実施形態のコンセントには、差込口21aおよび差込口22aからなるコンセント口が設けられるのである。なお、本実施形態では、上記各平栓刃がプラグの接極子を構成し、図3(a)における左右方向が差込口21b,21cを並設した規定方向となっている。   The cover 20 is formed with insertion ports 21a, 21b, and 21c penetrating through the front and back surfaces of the cover 20 at portions corresponding to the blade receiving springs 13a, 14a, and 14b described above. The insertion port 21a is opened in a rectangular shape that is long in the vertical direction of FIG. 3A, and a flat blade serving as a grounding electrode is inserted. Furthermore, the insertion ports 21b and 21c are opened in a rectangular shape so that a flat plug blade can be inserted, and are positioned below the insertion port 21a in FIG. . Both insertion ports 22a are inclined so that the distance on the lower end side is smaller than the distance on the upper end side. Therefore, the outlet according to the present embodiment is provided with an outlet including the insertion port 21a and the insertion port 22a. In this embodiment, each of the flat plug blades constitutes a plug armature, and the horizontal direction in FIG. 3A is a prescribed direction in which the insertion ports 21b and 21c are arranged in parallel.

また、コンセント口に対応する部位には、それぞれ差込口21a,21b,21cに何も差し込まれていないときに差込口21a,21b,21cを閉塞する蓋体23aが配置される。すなわち、蓋体23aは、コンセント口の複数個の差込口21a,21b,21cを一括して開閉する。また、蓋体23aはカバー20の内周面との間に保持されるコイルばねからなる復帰ばね24aによりコンセント口を閉塞する向きに付勢されており、コンセント口は常時は蓋体23aにより閉塞され、ほこりなどの異物がコンセント口に入らないようにしてある。蓋体23aにはコンセント口を閉塞しているときに差込口21a,21b,21cに臨む傾斜面がそれぞれ形成されており、平栓刃を差込口21a,21b,21cに差し込むと、平栓刃から傾斜面が受ける力により蓋体23aが復帰ばね24aのばね力に抗して開放されるようになっている。   Moreover, the lid | cover body 23a which obstruct | occludes the insertion ports 21a, 21b, and 21c when nothing is inserted in the insertion ports 21a, 21b, and 21c is arrange | positioned in the site | part corresponding to an outlet port, respectively. That is, the lid 23a collectively opens and closes the plurality of outlets 21a, 21b, 21c of the outlet port. The lid body 23a is biased in a direction to close the outlet port by a return spring 24a made of a coil spring held between the inner peripheral surface of the cover 20 and the outlet port is normally closed by the lid body 23a. In order to prevent foreign objects such as dust from entering the outlet. The lid body 23a is formed with inclined surfaces facing the insertion ports 21a, 21b, 21c when the outlet port is closed, and when the flat plug blade is inserted into the insertion ports 21a, 21b, 21c, The lid 23a is opened against the spring force of the return spring 24a by the force received by the inclined surface from the plug blade.

カバー20の内底面であって各端子14c,14cに対応する部位には、それぞれ端子14c,14cの基片16aに当接してボディ10からの端子14c,14cの浮き上がりを防止する押さえリブ25a,25aが突設されている。   On the inner bottom surface of the cover 20 and corresponding to the terminals 14c, 14c, presser ribs 25a that abut against the base pieces 16a of the terminals 14c, 14c to prevent the terminals 14c, 14c from lifting from the body 10, respectively. 25a protrudes.

また、ボディ10の右側面の上部にはスイッチ取付用切欠28が形成されている。さらに、ボディ10の右側面の上部には、ボディ10とカバー20とを結合した状態においてカバー20の右側面よりも右側に突出するハンドル載せ台19cを右側方に延設してある。ハンドル載せ台19cにはシーソ動作するハンドル50が載置される。ハンドル50は、右端部に手操作される操作体50aを有し、操作体50aの左側面に軸部50bを有する形状に形成される。操作体50aは上下方向に揺動可能となるように、ハンドル載せ台19cに対して後面の一部を接触させている。また、軸部50bは、スイッチ取付用切欠28に挿通され、軸部50bの前面に形成した軸突部50cをスイッチ取付用切欠28の前縁に形成した軸用切欠28aに噛み合わせることにより、軸突部50cの回りに回動可能になっている。   A switch mounting notch 28 is formed in the upper part of the right side surface of the body 10. Further, a handle platform 19c that protrudes to the right side of the right side surface of the cover 20 in a state where the body 10 and the cover 20 are coupled is extended to the right side at the upper part of the right side surface of the body 10. A handle 50 that performs seesaw operation is placed on the handle platform 19c. The handle 50 has an operating body 50a that is manually operated at the right end, and is formed in a shape having a shaft portion 50b on the left side surface of the operating body 50a. A part of the rear surface of the operating body 50a is brought into contact with the handle platform 19c so that the operating body 50a can swing in the vertical direction. The shaft portion 50b is inserted into the switch mounting notch 28, and the shaft protrusion 50c formed on the front surface of the shaft portion 50b is engaged with the shaft notch 28a formed on the front edge of the switch mounting notch 28. It can turn around the shaft protrusion 50c.

また、接地極用区画12cに収納される上述の導電板51においてハンドル載せ台19cの近傍部位には固定接点52を設けている。一方、接地極用区画12cに収納される端子14cには支持板53を接続してあり、支持板53の一端部には固定接点52に対して離接する可動接点54を設けた開閉子55の一端縁を当接させている。開閉子55は、固定接点52に可動接点54を当接させる位置と可動接点54を離す位置との間で、上記一端縁の回りに回動可能になっている。開閉子55の回動範囲はボディ10の内部形状で規定される。   A fixed contact 52 is provided in the vicinity of the handle platform 19c in the conductive plate 51 accommodated in the ground electrode section 12c. On the other hand, a support plate 53 is connected to the terminal 14 c housed in the ground electrode section 12 c, and an opening / closing element 55 provided with a movable contact 54 that is separated from the fixed contact 52 at one end of the support plate 53. One edge is brought into contact. The switch 55 is rotatable around the one end edge between a position where the movable contact 54 is brought into contact with the fixed contact 52 and a position where the movable contact 54 is separated. The rotation range of the opening / closing element 55 is defined by the internal shape of the body 10.

ハンドル50の軸部50bと開閉子55との間には、コイルばねからなる反転ばね56が保持されており、ハンドル50の揺動に伴って反転ばね56が伸縮するようにしてある。すなわち、ハンドル50はハンドル載せ台19cとの関係で規定される2位置の間で揺動可能であって、ハンドル50の一方の位置から他方の位置に揺動させると中間位置において反転ばね56が最圧縮され、その位置を越えると反転ばね56が急速に伸長し、開閉子55の位置が反転するようになっている。この動作はシーソスイッチと同様である。   A reversing spring 56 made of a coil spring is held between the shaft portion 50 b of the handle 50 and the opening / closing element 55, and the reversing spring 56 expands and contracts as the handle 50 swings. That is, the handle 50 can be swung between two positions defined by the relationship with the handle mount 19c. When the handle 50 is swung from one position to the other position, the reversing spring 56 is at the intermediate position. When the maximum compression is achieved and the position is exceeded, the reversing spring 56 expands rapidly, and the position of the opening / closing element 55 is reversed. This operation is the same as that of the seesaw switch.

上述の構成により、ハンドル50を揺動させる操作を行うと、開閉子55が回動し可動接点54が固定接点52に対して離接するから、刃受ばね14bと端子14cとの間の電路を開閉することができる。   With the above-described configuration, when the operation of swinging the handle 50 is performed, the switch 55 rotates and the movable contact 54 is separated from the fixed contact 52. Therefore, the electric path between the blade receiving spring 14b and the terminal 14c is provided. Can be opened and closed.

Both the plate body 30 and the decorative plate 40 have a rectangular frame shape. The plate body 30 has an attachment opening 31 for attaching the container 1, and the decorative plate 30 is for exposing the front surface of the container 1. An exposure notch 42 for exposing the handle 50 is continuously formed in the upper right portion of the exposure opening 41. The back surface of the decorative plate 40 is provided with engagement legs 40a (see FIG. 4) that are respectively inserted into four coupling holes 30a provided in the peripheral portion of the plate body 30, and hooks provided at the front ends of the engagement legs 40a are engaged. The decorative plate 40 is coupled to the plate body 30 by engaging with the peripheral portion of the joint hole 30a. Further, the removal piece 30b extends on the lower edge of the plate body 30, and the removal groove 40b with which the removal piece 30b is engaged is formed on the lower edge of the decorative plate 40. The decorative plate 40 is attached to the plate body 30. In this state, the decorative plate 40 can be removed from the plate body 30 by inserting a tool such as a flathead screwdriver between the removal piece 30b and the removal groove 40b and using the tool as a lever.

器体1は施工時にはプレートボディ30に保持されるのであって、器体1をプレートボディ30と結合する構成として、ボディ10の左右両側部には外側面の一部(ボディ10の開口縁の一部から外側)に保持突片18が突設され、カバー20の上下両側面の一部(カバー20の上下両面の中央部)には保持凸部26が突設される。保持突片18は挿通用スリット10dに対応する部位で上下に2分されている。カバー20においてボディ10の保持突片18に対応する部位には、保持突片18と噛み合う切欠部27が形成され、カバー20の両側部において切欠部27以外の部位の後面と保持突片18の後面とが面一になるようにしてある。また、保持凸部26の前面は保持突片18の後面よりも前方に位置し、保持凸部26は後方に向かって突出寸法を小さくする断面形状に形成されている。   The body 1 is held by the plate body 30 at the time of construction. As a configuration in which the body 1 is coupled to the plate body 30, a part of the outer surface (the opening edge of the body 10 is formed on both the left and right sides of the body 10. Holding protrusions 18 project from a part to the outside, and holding projections 26 project from a part of the upper and lower side surfaces of the cover 20 (the central part of the upper and lower surfaces of the cover 20). The holding projecting piece 18 is vertically divided into two at a portion corresponding to the insertion slit 10d. A cutout 27 that meshes with the holding protrusion 18 is formed in a portion of the cover 20 corresponding to the holding protrusion 18 of the body 10, and the rear surface of the portion other than the cutout 27 and the holding protrusion 18 on both sides of the cover 20. It is designed to be flush with the rear surface. Further, the front surface of the holding convex portion 26 is positioned in front of the rear surface of the holding protruding piece 18, and the holding convex portion 26 is formed in a cross-sectional shape that reduces the protruding dimension toward the rear.

プレートボディ30は、図2および図4に示すように、左右一対の取付枠片32と、両取付枠片32の上下各端部間をそれぞれ連続一体に連結する連結片33とを有した矩形枠状であって、各取付枠片32の長手方向(図4の上下方向)の中央部には上下に長い長孔状の取付用孔32aが形成される。取付用孔32aは、施工面にプレートボディ30を固定するための取付ねじを挿入するために設けられている。例えば、施工面にボックスを埋め込んでおき、ボックスに設けたねじ孔に取付ねじを螺合させることによって、プレートボディ30を施工面に固定することができる。また、連結片33には、左右方向に延長され表裏に貫通する弾性付与孔34が形成されており、弾性付与孔34と取付用開口31との間に係止押さえ片35が形成される。したがって、係止押さえ片35は取付用開口31の内側面に直交する方向に可撓性を有することになる。取付用開口31の左右の両内側面の適所には係止受け片36が突設される。   As shown in FIGS. 2 and 4, the plate body 30 has a rectangular shape having a pair of left and right mounting frame pieces 32 and connecting pieces 33 that connect the upper and lower ends of both mounting frame pieces 32 continuously and integrally. An attachment hole 32a having a long hole shape is formed at the center in the longitudinal direction (vertical direction in FIG. 4) of each attachment frame piece 32 in the frame shape. The mounting hole 32a is provided for inserting a mounting screw for fixing the plate body 30 to the construction surface. For example, the plate body 30 can be fixed to the construction surface by embedding a box in the construction surface and screwing a mounting screw into a screw hole provided in the box. In addition, the connection piece 33 is formed with an elasticity imparting hole 34 extending in the left-right direction and penetrating the front and back, and a locking pressing piece 35 is formed between the elasticity imparting hole 34 and the mounting opening 31. Therefore, the locking pressing piece 35 has flexibility in a direction orthogonal to the inner surface of the mounting opening 31. Locking receiving pieces 36 protrude from appropriate positions on both the left and right inner side surfaces of the mounting opening 31.

プレートボディ30に器体1を装着するには、器体1をプレートボディ30の前方から取付用開口31の中に挿入する。ボディ10の後部が取付用開口31に挿入されると、ボディ10に設けた保持突片18の後面が係止受け片36の前面に当接して後方への移動が規制される。また、保持凸部26が係止押さえ片35を押圧することで、係止押さえ片35が外側に撓み、保持凸部26が係止押さえ片35を乗り越えると、係止押さえ片35の後面である係止面に保持凸部26の前面が当接することで器体1の前方への移動が規制される。すなわち、器体1がプレートボディ30に結合された状態において、器体1のボディ10とカバー20とが、プレートボディ30の係止受け片36と係止押さえ片35との間で挟持されることになるから、組立突起20aが何らかの原因(材料の熱収縮や破損など)で組立片10aに設けた組立孔10bから外れたとしても、ボディ10とカバー20とが外れることがない。その結果、ボディ10とカバー20との材料の選択の幅が広がる。   In order to attach the container 1 to the plate body 30, the container 1 is inserted into the mounting opening 31 from the front of the plate body 30. When the rear portion of the body 10 is inserted into the mounting opening 31, the rear surface of the holding projection piece 18 provided on the body 10 comes into contact with the front surface of the locking receiving piece 36, and the rearward movement is restricted. Further, when the holding convex portion 26 presses the locking pressing piece 35, the locking pressing piece 35 is bent outward, and when the holding convex portion 26 gets over the locking pressing piece 35, the rear surface of the locking pressing piece 35 is formed. When the front surface of the holding convex portion 26 comes into contact with a certain locking surface, the forward movement of the body 1 is restricted. That is, in a state where the container body 1 is coupled to the plate body 30, the body 10 and the cover 20 of the container body 1 are sandwiched between the locking receiving piece 36 and the locking pressing piece 35 of the plate body 30. Therefore, even if the assembly protrusion 20a is detached from the assembly hole 10b provided in the assembly piece 10a for some reason (such as heat shrinkage or damage of the material), the body 10 and the cover 20 are not detached. As a result, the range of selection of materials for the body 10 and the cover 20 is expanded.

ところで、図2に示すように、プレートボディ30に設けた取付用開口31の内側面において左右の取付用孔32aの近傍には位置決め突部37が突設されている。言い換えると、位置決め突部37の上下に隣接する部位には係止受け片36は形成されず、位置決め突部37と上下の係止受け片36との間には凹所が形成される。一方、図2に示すように、カバー20の左右両側面には位置決め突部37に係合する位置決め溝29が形成されている。位置決め溝29は、器体1の上下方向の中心位置に形成されている。すなわち、器体1をプレートボディ30に装着した状態で、取付用開口31の開口面内における上下方向の対称位置に位置決め突部37と位置決め溝29とが形成されることになる。   By the way, as shown in FIG. 2, positioning protrusions 37 are provided in the vicinity of the left and right mounting holes 32 a on the inner surface of the mounting opening 31 provided in the plate body 30. In other words, the latch receiving piece 36 is not formed at a position adjacent to the upper and lower portions of the positioning projection 37, and a recess is formed between the positioning projection 37 and the upper and lower latch receiving pieces 36. On the other hand, as shown in FIG. 2, positioning grooves 29 that engage with the positioning protrusions 37 are formed on the left and right side surfaces of the cover 20. The positioning groove 29 is formed at the center position in the vertical direction of the container 1. That is, the positioning projection 37 and the positioning groove 29 are formed at symmetrical positions in the vertical direction within the opening surface of the mounting opening 31 in a state where the container body 1 is mounted on the plate body 30.

ところで、上述の規定方向に並設された2つの差込口21b,21cそれぞれに対応して配置される刃受ばね14a,14bは、互いに対向し平栓刃を挟持する一対のばね片およびばね片の後端縁同士を連続一体に連結した連結片を有しており、右側に配置される刃受ばね14bは、連結片の後面に重ねて配置される支持片61に対して連結片が厚み方向に直交する面内で回動自在となるようにかしめ鋲71により結合されている。なお、支持片61は上述の導電板51の一部により構成されており、かしめ鋲71を挿通させる挿通孔62が形成されている。   By the way, the blade receiving springs 14a and 14b arranged corresponding to the two insertion ports 21b and 21c arranged in parallel in the prescribed direction are a pair of spring pieces and springs that face each other and sandwich the flat plug blade. The blade receiving spring 14b arranged on the right side is connected to the support piece 61 arranged on the rear surface of the connecting piece. It is connected by a caulking rod 71 so as to be rotatable in a plane orthogonal to the thickness direction. The support piece 61 is constituted by a part of the conductive plate 51 described above, and an insertion hole 62 through which the caulking rod 71 is inserted is formed.

ここにおいて、刃受ばね14bは、ボディ10内において図1(a),(b)に示すように配置されるものであるが、ボディ10に組み込む前に連結片の厚み方向に直交する面内で連結片を180度回転させると一対のばね片の前端部と他方の刃受ばね14aとの間隔が変わるように一対のばね片の形状を非対称に形成してある(連結片の長手方向に直交し連結片を2分する平面に対して非対称に形成されている)。したがって、刃受ばね14bにおいて一対のばね片の後端縁同士を連続一体に連結した連結片を厚み方向に直交する面内で180度回転させることにより、一対のばね片の前端部と他方の刃受ばね14aとの間隔を図1(c),(d)に示すように変えることができる。上述の図2〜図4にて説明した定格電流が10Aのスイッチ付きコンセントでは刃受ばね14bがボディ10内において図1(a),(b)に示すように収納され、図5および図6に示した定格電流が16Aのスイッチ付きコンセントでは刃受ばね14bが図1(c),(d)に示すように収納されており、後者の方が一対のばね片の前端部と他方の刃受ばね14aとの間隔が大きくなっている。しかして、本実施形態では、定格の違いに応じて規定方向の差込口21b,21cの間隔が異なる他のコンセントと刃受ばね14bの共通化を図ることができ、刃受ばね14bの部品コストを低減できて、低コスト化を図れる。なお、本実施形態では、規定方向に並設される刃受ばね14a,14bのうちの一方の刃受ばね14bを180度回転させることにより上記間隔を変えるようにしているが、規定方向に並設される刃受ばね14a,14bの少なくとも一方を180度回転できるように構成すればよい。   Here, the blade receiving spring 14b is arranged in the body 10 as shown in FIGS. 1 (a) and 1 (b), but before being incorporated in the body 10, it is in a plane perpendicular to the thickness direction of the connecting piece. When the connecting piece is rotated 180 degrees, the shape of the pair of spring pieces is formed asymmetrically so that the distance between the front end of the pair of spring pieces and the other blade receiving spring 14a changes (in the longitudinal direction of the connecting piece). It is formed asymmetrically with respect to a plane that is orthogonal and bisects the connecting piece). Accordingly, by rotating the connecting piece obtained by continuously and integrally connecting the rear end edges of the pair of spring pieces in the blade receiving spring 14b within a plane orthogonal to the thickness direction, the front end portion of the pair of spring pieces and the other end of the pair of spring pieces are rotated. The distance from the blade receiving spring 14a can be changed as shown in FIGS. 1 (c) and 1 (d). 2 to 4, the blade socket spring 14b is housed in the body 10 as shown in FIGS. 1 (a) and 1 (b). 1B, the blade receiving spring 14b is housed as shown in FIGS. 1 (c) and 1 (d). The latter is the front end of the pair of spring pieces and the other blade. The space | interval with the receiving spring 14a is large. Therefore, in this embodiment, it is possible to share the blade receiving spring 14b with other outlets having different intervals between the insertion ports 21b and 21c in the specified direction according to the difference in rating, and the components of the blade receiving spring 14b. Costs can be reduced and costs can be reduced. In the present embodiment, the interval is changed by rotating one blade receiving spring 14b of the blade receiving springs 14a and 14b arranged in parallel in the specified direction by 180 degrees. What is necessary is just to comprise so that at least one of the blade receiving springs 14a and 14b provided can be rotated 180 degree | times.

また、上述の刃受ばね13aは、端子13bの基片16aの前面に重ねて接続される接続片13cを有し、接続片13cの両端縁から前方へ向かう延設片13dが設けられているので、ボディ10からの刃受ばね13aの浮き上がりを防止するためにカバー20の内底面からボディ10側に突出する押さえリブ25bの突出寸法を従来に比べて小さくすることができる。すなわち、本実施形態では、刃受ばね13cの浮き上がりを防止する押さえリブ25bが各延設片13dの先端面にそれぞれ当接するようにすればよいから、カバー20の内底面からの押さえリブ25bの突出寸法を小さくすることができて押さえリブ25bの強度を確保しやすくなる。   The blade receiving spring 13a described above has a connection piece 13c that is connected to the front surface of the base piece 16a of the terminal 13b, and is provided with an extending piece 13d that extends forward from both end edges of the connection piece 13c. Therefore, in order to prevent the blade receiving spring 13a from being lifted from the body 10, the protruding dimension of the holding rib 25b protruding from the inner bottom surface of the cover 20 toward the body 10 can be reduced as compared with the conventional case. That is, in this embodiment, the holding ribs 25b that prevent the blade receiving springs 13c from lifting up may be brought into contact with the distal end surfaces of the extending pieces 13d. The projecting dimension can be reduced, and the strength of the holding rib 25b can be easily secured.

(実施形態2)
図7および図8に示す本実施形態のコンセントの基本構成は実施形態1にて説明した図2〜図4のスイッチ付きコンセントと略同じであり、スイッチに関する部材を備えておらず、刃受ばね14bが実施形態1と同様の支持片を有する導電板を介して端子14cに接続されている点などが相違する。
(Embodiment 2)
The basic configuration of the outlet of this embodiment shown in FIGS. 7 and 8 is substantially the same as the outlet with a switch of FIGS. 2 to 4 described in the first embodiment. The difference is that 14b is connected to the terminal 14c via a conductive plate having a support piece similar to that of the first embodiment.

また、本実施形態では、実施形態1にて説明したハンドル載せ台19cを設ける代わりに、ボディ10の右側面の上部にはカバー20との結合時にカバー20の右側面よりも右側に向かって第1の覆い片19aが突設され、第1の覆い片19aの基部付近には前方に向かって第2の覆い片19bが突設されており、第1および第2の覆い片19a,19bが、カバー20のスイッチ取付用切欠28に噛み合うので、ボディ10にカバー20を結合した状態では、スイッチ取付用切欠28は閉塞される。他の構成は実施形態1と同じである。
(実施形態3)
図9に示す本実施形態のコンセントの基本構成は実施形態2と略同じであり、1つの器体に形状の異なる2個のコンセント口を備えている点が相違する。すなわち、一方のコンセント口は、実施形態2と同様に差込口21a,21b,21cにより構成され、他方のコンセント口が2つの差込口22b,22bにより構成されている。また、ボディ10内には、差込口22b,22bに対応する部位に刃受ばね14e,14eが収納されている。
差込口22bは丸ピンと平栓刃との両方を挿入することが可能な形状であって、開口面が半円形状ないし半楕円形状に形成される。差込口22bは左右方向(上記規定方向と同じ方向)に並設されており、両差込口22bの最近接部位が上下方向の直線状に形成され、この直線状の部位に沿って平栓刃が挿入される。平栓刃を挿入する部位は丸ピンを挿入する部位よりも広幅に形成される。しかして、本実施形態のコンセントには、差込口22b,22bからなるコンセント口と、差込口21a,21b,2cからなるコンセント口とが設けられるのである。
Further, in this embodiment, instead of providing the handle platform 19c described in the first embodiment, the upper portion of the right side surface of the body 10 is positioned more rightward than the right side surface of the cover 20 when coupled to the cover 20. One cover piece 19a is projected, and a second cover piece 19b is projected forward near the base of the first cover piece 19a. The first and second cover pieces 19a, 19b are Since the switch 20 is engaged with the switch mounting notch 28 of the cover 20, the switch mounting notch 28 is closed when the cover 20 is coupled to the body 10. Other configurations are the same as those of the first embodiment.
(Embodiment 3)
The basic configuration of the outlet of the present embodiment shown in FIG. 9 is substantially the same as that of the second embodiment, and is different in that one outlet has two outlets having different shapes. That is, one outlet port is configured by the insertion ports 21a, 21b, and 21c similarly to the second embodiment, and the other outlet port is configured by the two insertion ports 22b and 22b. Further, in the body 10, blade receiving springs 14e and 14e are housed in portions corresponding to the insertion ports 22b and 22b.
The insertion port 22b has a shape into which both a round pin and a flat plug blade can be inserted, and the opening surface is formed in a semicircular shape or a semi-elliptical shape. The insertion ports 22b are arranged side by side in the left-right direction (the same direction as the specified direction), and the closest part of both insertion ports 22b is formed in a straight line in the vertical direction, and is flat along the straight line part. The blade is inserted. The part for inserting the flat plug blade is formed wider than the part for inserting the round pin. Thus, the outlet of the present embodiment is provided with an outlet port composed of the insertion ports 22b and 22b and an outlet port composed of the insertion ports 21a, 21b and 2c.

刃受ばね14eは、図10に示すように、平栓刃と丸ピンとの両方を受けることができるものであり、丸ピンを保持する部位は2枚のばね片142,142を対向させた形に配置し、両ばね片142,142の一方の側面に1枚のばね片141を対向させることにより、2枚のばね片142,142の側面と1枚のばね片141との間に平栓刃を保持する構成を採用している。なお、図11は金属部材から形成された刃受ばね14eの展開図であり、図11に示す基部140の中央部の上縁(前縁)からばね片141が延設され、基部140の両端部それぞれの上縁からばね片142が延設され、基部140の両側縁から端子14cの鎖錠片16bの側縁から側方へ延設された結合片16dにかしめ固定により接続可能なリード片143が延設されている。   As shown in FIG. 10, the blade receiving spring 14e is capable of receiving both a flat plug blade and a round pin, and a portion for holding the round pin is a shape in which two spring pieces 142 and 142 are opposed to each other. The flat spring plug is provided between the side surfaces of the two spring pieces 142 and 142 and the one spring piece 141 by making one spring piece 141 face one side surface of both spring pieces 142 and 142. The structure which holds a blade is adopted. 11 is a development view of the blade receiving spring 14e formed of a metal member. A spring piece 141 is extended from the upper edge (front edge) of the central portion of the base portion 140 shown in FIG. Spring pieces 142 are extended from the upper edges of the respective portions, and lead pieces connectable by caulking and fixing to coupling pieces 16d extending from both side edges of the base portion 140 to the side edges of the locking pieces 16b of the terminals 14c. 143 is extended.

また、本実施形態では、端子14c,14cに一端部が接続されるリード板14f,14gの他端部が刃受ばね14a,14bにおける連結片の後面に重ねて配置される支持片61を構成しており、刃受ばね14a,14bにおける連結片がかしめ鋲により支持片61,61に回動自在に結合されている。   Further, in the present embodiment, the support piece 61 is configured in which the other end portions of the lead plates 14f and 14g whose one end portions are connected to the terminals 14c and 14c are arranged so as to overlap the rear surfaces of the connecting pieces of the blade receiving springs 14a and 14b. The connecting pieces of the blade receiving springs 14a and 14b are rotatably coupled to the support pieces 61 and 61 by caulking hooks.

また、ボディ10の上部で上記規定方向に並設される刃受ばね14e,14eは、端子14c,14cに接続されるリード板143が連続一体に設けられ、且つ上記規定方向を左右方向とするとき左右対称の形状に形成されているので、部品点数の削減による低コスト化が図れ、また、リード板と刃受ばねとをかしめ固定する場合に比べて組立作業が容易になる。   Further, the blade receiving springs 14e and 14e arranged in parallel in the specified direction at the upper part of the body 10 are provided with a continuous lead plate 143 connected to the terminals 14c and 14c, and the specified direction is the left-right direction. Since it is sometimes formed in a symmetrical shape, the cost can be reduced by reducing the number of parts, and the assembling work is facilitated as compared with the case where the lead plate and the blade receiving spring are caulked and fixed.
