Description

本発明は、検出基板の取付構造に関するものである。 The present invention relates to a mounting structure for a detection board.

特許文献１に記載されているように、漏電検出回路や警報回路を組み込んだ検出基板を回路遮断器に備えることが知られている。ところで、基板にはコンデンサなどの電子回路や基板への入出線があるが、他の機構部などと干渉しないようにするために、基板は組付方向が定められている。組付作業時に、組付方向を間違えないようにする工夫として、基板を左右非対称な凹凸形状に形成するとともに、組み込みされる回路遮断器のベース部も基板に対応した形状とすることがなされている。 As described in Patent Document 1, it is known that a circuit breaker is provided with a detection board incorporating a leakage detection circuit and an alarm circuit. The board contains electronic circuits such as capacitors and input/output lines to the board, but the installation direction of the board is determined to prevent interference with other mechanical parts. In order to prevent the assembly direction from being incorrect during assembly work, the board is formed into an asymmetrical uneven shape, and the base part of the circuit breaker to be installed is also shaped to correspond to the board.

特開２００２－００８５１３号公報JP 2002-008513 A

ところで、このような形状とすると、検出基板を取り付けるためのスペースが大きくなりがちである。また、基板が複雑な形状であるため、がたつきなく固定できるように、基板の固定部の取付位置を考慮するのが手間であった。 However, this type of shape tends to require a large amount of space to install the detection board. Also, because the board has a complex shape, it is time-consuming to consider the installation position of the board's fixing part so that it can be fixed without rattling.

本件の発明者は、この点について鋭意検討することにより、解決を試みた。本発明が解決しようとする課題は、向きを間違えないように検出基板を回路遮断器に取り付けられるようにするとともに、検出基板をがたつきなく回路遮断器に取り付けられるようにすることである。 The inventor of this case has thoroughly investigated this issue and attempted to solve it. The problem that this invention aims to solve is to make it possible to attach a detection board to a circuit breaker in the correct orientation, and to make it possible to attach the detection board to the circuit breaker without rattling.

上記課題を解決するため、回路遮断器へ固定される方形状の検出基板の取付構造であって、検出基板の一辺と、その一辺の反対側に位置する辺に回路遮断器へ取り付けるための取付部を複数備え、複数の取付部の少なくとも１つの取付部は他の取付部と異なる形状であり、検出基板の一辺と、その一辺の反対側に位置する辺が、非線対称であることを特徴とする検出基板の取付構造とする。 To solve the above problem, the mounting structure for a rectangular detection board that is fixed to a circuit breaker is characterized in that the detection board has a plurality of mounting parts for mounting to the circuit breaker on one side and the side opposite the one side, at least one of the mounting parts has a shape different from the other mounting parts, and the one side of the detection board and the side opposite the one side are asymmetrical.

また、検出基板に切欠で構成した取付部を備え、回路遮断器に固定接触子を固定するベース部を備え、切欠に接続する被取付部を、ベース部から突出するように形成した突起部に備え、ベース部と検出基板の間に空間部を有するように、検出基板を突起部で支えることが可能な構成とすることが好ましい。 It is also preferable that the detection board is provided with an attachment portion formed of a notch, the circuit breaker is provided with a base portion for fixing the fixed contact, and the attachment portion connected to the notch is provided on a protrusion formed to protrude from the base portion, so that the detection board can be supported by the protrusion, with a space between the base portion and the detection board.

また、突起部がベース部の背面側から突出するように形成され、サブベース部が突起部に支えられた検出基板を覆うように形成され、検出基板を突起部で支えた状態でサブベース部と検出基板の間に空間を有することが可能な構成とすることが好ましい。 It is also preferable that the protrusions are formed to protrude from the rear side of the base, the sub-base is formed to cover the detection board supported by the protrusions, and a space is formed between the sub-base and the detection board when the detection board is supported by the protrusions.

本発明では、向きを間違えないように検出基板を回路遮断器に取り付けられるようにするとともに、検出基板をがたつきなく回路遮断器に取り付けられるようにすることが可能となる。 The present invention makes it possible to attach the detection board to the circuit breaker in the correct orientation, and also makes it possible to attach the detection board to the circuit breaker without rattling.

以下に発明を実施するための形態を示す。本実施形態の検出基板５０の取付構造は、回路遮断器１へ固定される方形状の検出基板５０を取り付けるものである。この取付構造は、検出基板５０の一辺と、その一辺の反対側に位置する辺に回路遮断器１へ取り付けるための取付部５１を複数備えている。また、複数の取付部５１の少なくとも１つの取付部５１は他の取付部５１と異なる形状であり、検出基板５０の一辺と、その一辺の反対側に位置する辺が、非線対称である。このため、向きを間違えないように検出基板５０を回路遮断器１に取り付けられるとともに、検出基板５０をがたつきなく回路遮断器１に取り付けることが可能となる。 The following is an embodiment of the invention. The mounting structure for the detection board 50 in this embodiment is for mounting a rectangular detection board 50 that is fixed to the circuit breaker 1. This mounting structure has multiple mounting parts 51 for mounting to the circuit breaker 1 on one side of the detection board 50 and the side opposite the first side. At least one of the multiple mounting parts 51 has a different shape from the other mounting parts 51, and the one side of the detection board 50 and the side opposite the first side are asymmetrical. This allows the detection board 50 to be mounted to the circuit breaker 1 in the correct orientation, and allows the detection board 50 to be mounted to the circuit breaker 1 without rattling.

実施形態の回路遮断器１は、可動接点２１、固定接点２２、可動接点２１を動作させるための動作機構部２３を収納するベース部１１を備えている。また、ベース部１１の開口部を覆い、ハンドルを露出するカバー部１２を備えている。更には、カバー部１２の反対端部に形成され、検出基板５０や配線を覆うサブベース部１３を備えている。図１から図３に示されていることから理解されるように、実施形態の回路遮断器１の大まかな外形はこのベース部１１、カバー部１２、サブベース部１３により構成されている。 The circuit breaker 1 of the embodiment includes a base portion 11 that houses a movable contact 21, a fixed contact 22, and an operating mechanism portion 23 for operating the movable contact 21. It also includes a cover portion 12 that covers the opening of the base portion 11 and exposes the handle. It also includes a sub-base portion 13 that is formed at the opposite end of the cover portion 12 and covers the detection board 50 and wiring. As can be seen from Figures 1 to 3, the general outer shape of the circuit breaker 1 of the embodiment is formed by the base portion 11, the cover portion 12, and the sub-base portion 13.

実施形態の取付構造では、ベース部１１の背面側に検出基板５０を固定させている。なお、サブベース部１３は検出基板５０を覆うようにベース部１１の背面側に取り付けられる。 In the mounting structure of the embodiment, the detection board 50 is fixed to the rear side of the base part 11. The sub-base part 13 is attached to the rear side of the base part 11 so as to cover the detection board 50.

図３から図６に示すことから理解されるように、実施形態の回路遮断器１に取り付けられる検出基板５０は方形状に形成されている。このため、検出基板５０が大きくなることを抑制することができる。また、実施形態の検出基板５０は、方形を成す四辺のうち、互いに向き合う位置にある二つの辺に複数の取付部５１を有している。この取付部５１を被取付部と接続することで検出基板５０を支えることができる。なお、図４に示す例では取付部５１は検出基板５０の上辺及び下辺に備えられているが、右辺および左辺には備えられていない。 As can be seen from Figs. 3 to 6, the detection board 50 attached to the circuit breaker 1 of the embodiment is formed in a rectangular shape. This makes it possible to prevent the detection board 50 from becoming large. Furthermore, the detection board 50 of the embodiment has multiple mounting portions 51 on two of the four sides that form a rectangle and are positioned to face each other. The detection board 50 can be supported by connecting the mounting portions 51 to the mounting portion. In the example shown in Fig. 4, the mounting portions 51 are provided on the upper and lower sides of the detection board 50, but not on the right and left sides.

複数の取付部５１の少なくとも１つの取付部５１が他の取付部５１と異なる形状であり、検出基板５０の一辺と、その一辺の反対側に位置する辺が、非線対称であるようにすれば、検出基板５０を上下若しくは左右反対の向きで被取付部に取り付けようとしても、取り付けることができない。したがって、適切な向きでのみ検出基板５０を取り付けることができる。なお、図４に示す例では、検出基板５０の上辺の右側に備えられている取付部５１の左右方向の長さが、他の取付部５１と異なる構成となっている。 If at least one of the multiple mounting parts 51 has a different shape from the other mounting parts 51 and one side of the detection board 50 and the side opposite that side are asymmetrical, the detection board 50 cannot be attached to the mounting part in the up-down or left-right reversed orientation. Therefore, the detection board 50 can only be attached in the appropriate orientation. In the example shown in Figure 4, the mounting part 51 on the right side of the upper side of the detection board 50 has a different left-right length from the other mounting parts 51.

また、図４に示す例では、検出基板５０の一辺における取付部５１の「位置」は、その一辺の反対側に位置する辺における取付部５１の「位置」と線対称となるようにしている。このため、被取付部の位置の調整が容易である。 In the example shown in FIG. 4, the "position" of the mounting part 51 on one side of the detection board 50 is linearly symmetrical to the "position" of the mounting part 51 on the side opposite that side. This makes it easy to adjust the position of the mounting part.

図４に示す例の取付部５１は切欠である。このため、検出基板５０が大きくなることを抑制することができる。この取付部５１に接続する部分は、ベース部１１から突出するように形成した突起部１４に備えられた被取付部である。図６及び図７に示す例から理解されるように、実施形態では、被取付部は、突起部１４の先端部に備えられた嵌合部１５であり、この嵌合部１５を検出基板５０の切欠に嵌合させている。なお、実施形態ではベース部１１から複数の突起部１４が突出するような構成としており、それらの突起部１４により、検出基板５０の一辺側の部分と、その一辺の反対側に位置する辺側の部分が支えられている。なお、図７に示すことから理解されるように、実施形態では嵌合部１５と嵌合部１５の間に検出基板５０を挟み込むようにして、検出基板５０を支持している。 The mounting portion 51 in the example shown in FIG. 4 is a notch. Therefore, it is possible to prevent the detection board 50 from becoming large. The portion connected to this mounting portion 51 is a mounting portion provided on the protrusion portion 14 formed to protrude from the base portion 11. As can be understood from the examples shown in FIG. 6 and FIG. 7, in the embodiment, the mounting portion is a fitting portion 15 provided on the tip portion of the protrusion portion 14, and this fitting portion 15 is fitted into the notch of the detection board 50. Note that in the embodiment, a configuration is adopted in which a plurality of protrusion portions 14 protrude from the base portion 11, and these protrusion portions 14 support a portion of one side of the detection board 50 and a portion of the side located opposite to that side. Note that, as can be understood from FIG. 7, in the embodiment, the detection board 50 is supported by sandwiching the detection board 50 between the fitting portions 15.

上記したように、実施形態では、ベース部１１から延びる複数の突起部１４により、検出基板５０が支持されるが、この時、ベース部１１と検出基板５０の間に空間部７１を有するように、検出基板５０を支えることができる（図８参照）。したがって、ベース部１１から検出基板５０に向けて熱が伝わることを抑制することができる。また、ベース部１１と検出基板５０の間の空間部７１に、基板に備えられた電子回路の部品などを配置することもできる。このようにしても、電子回路の部品などがベース部１１と接触することは回避することができるため、ベース部１１から熱が伝わり電子回路の部品などが故障・変形することを抑制することができる。 As described above, in the embodiment, the detection board 50 is supported by a plurality of protrusions 14 extending from the base portion 11, and at this time, the detection board 50 can be supported so that there is a space 71 between the base portion 11 and the detection board 50 (see FIG. 8). Therefore, it is possible to suppress the transfer of heat from the base portion 11 to the detection board 50. In addition, electronic circuit components provided on the board can be arranged in the space 71 between the base portion 11 and the detection board 50. Even in this way, it is possible to prevent the electronic circuit components from coming into contact with the base portion 11, and therefore it is possible to suppress the transfer of heat from the base portion 11 and the failure or deformation of the electronic circuit components.

また、実施形態では、突起部１４がベース部１１の背面側から突出するように形成されているが、サブベース部１３が突起部１４に支えられた検出基板５０を覆うように構成している。このため、検出基板５０がむき出しになることを回避することができる。 In addition, in the embodiment, the protrusion 14 is formed to protrude from the rear side of the base portion 11, but the sub-base portion 13 is configured to cover the detection board 50 supported by the protrusion 14. This makes it possible to prevent the detection board 50 from being exposed.

また、実施形態のサブベース部１３は、検出基板５０を突起部１４で支えた状態でサブベース部１３と検出基板５０の間に空間７３を有することを可能とする構成としている。このため、サブベース部１３側から検出基板５０に熱が伝わることを抑制することができる。 In addition, the sub-base portion 13 of the embodiment is configured to allow a space 73 to be formed between the sub-base portion 13 and the detection board 50 while the detection board 50 is supported by the protrusion portion 14. This makes it possible to suppress the transfer of heat from the sub-base portion 13 to the detection board 50.

以上、実施形態を例に挙げて本発明について説明してきたが、本発明は上記実施形態に限定されることはなく、各種の態様とすることが可能である。例えば、検出基板の三辺若しくは四辺に取付部を備えた構成とすることも可能である。 The present invention has been described above using examples of embodiments, but the present invention is not limited to the above-mentioned embodiments and can be implemented in various forms. For example, it is also possible to provide a configuration in which mounting portions are provided on three or four sides of the detection board.
