Description

本発明は、分電盤内に装着するブレーカの取付構造に関する。   The present invention relates to a structure for mounting a breaker mounted in a distribution board.

従来より、分電盤内においてブレーカを取付パネルへと固定するにあたっては、ねじを用いてブレーカを取付パネルに螺着する構造や、専用の弾性部材を利用して取り付ける構造が採用されている。また、ブレーカの一次側（電源接続側）がプラグ状に形成されているものにあっては、たとえば特許文献１に記載されているように、弾性を有する合成樹脂製の取付部材を用いてブレーカを取付パネルに取り付ける構造が一般的に採用されている。   Conventionally, in order to fix the breaker to the mounting panel in the distribution board, a structure in which the breaker is screwed to the mounting panel using a screw or a structure in which a dedicated elastic member is used is employed. Moreover, in the case where the primary side (power connection side) of the breaker is formed in a plug shape, for example, as described in Patent Document 1, a breaker is formed using an elastic synthetic resin mounting member. In general, a structure for attaching to a mounting panel is employed.

特開２００１−３２７００９号公報Japanese Patent Laid-Open No. 2001-327007

ここで、従来のブレーカ取付構造について、図６及び７に基づき説明する。
図６（ａ）は、ねじ３５を利用した取付構造を示す説明図であって、ブレーカ３１の基部には係止凹部３２、３２が設けられている。一方、取付パネル３３には、ブレーカ３１の係止凹部３２、３２に係止する鉤状の係止爪３４、３４が突設されている。そして、各係止爪３４を係止凹部３２に係止させた状態で、一方の係止爪３４をねじ３５により締着することによってブレーカ３１を取付パネル３３に固定する。
尚、ねじを利用する取付構造としては、ブレーカにねじ孔を有する取付片を設け、該取付片を取付パネルに螺着してブレーカを固定するような構造もある。 Here, a conventional breaker mounting structure will be described with reference to FIGS.
FIG. 6A is an explanatory view showing an attachment structure using the screw 35, and locking recesses 32, 32 are provided at the base of the breaker 31. On the other hand, hook-like locking claws 34, 34 that are locked to the locking recesses 32, 32 of the breaker 31 protrude from the mounting panel 33. The breaker 31 is fixed to the mounting panel 33 by fastening one locking claw 34 with a screw 35 in a state where each locking claw 34 is locked to the locking recess 32.
In addition, as an attachment structure using a screw, there is also a structure in which an attachment piece having a screw hole is provided in the breaker, and the attachment piece is screwed to an attachment panel to fix the breaker.

図６（ｂ）は、専用の弾性部材３６を利用した取付構造を示す説明図であって、取付パネル３３に設けられる一方の係止爪３４を係止凸部を有する弾性部材３６としている。したがって、ブレーカ３１を上方から挿入すれば、弾性部材３６の係止凸部とブレーカ３１の係止凹部３２とが係止し、ブレーカ３１が取付パネル３３に固定される。   FIG. 6B is an explanatory view showing a mounting structure using a dedicated elastic member 36, and one locking claw 34 provided on the mounting panel 33 is an elastic member 36 having a locking projection. Therefore, when the breaker 31 is inserted from above, the locking projection of the elastic member 36 and the locking recess 32 of the breaker 31 are locked, and the breaker 31 is fixed to the mounting panel 33.

図７は、合成樹脂製の取付部材４８を利用した取付構造を示す説明図である。
ブレーカ４１の前面側には、嵌合凸部４２が一体的に突設されており、背面側には、係止凹部（図示せず）が設けられている。一方、取付パネル４３には、係止凹部に係止する鉤状の係止爪４４が一体的に突設されている。また、取付パネル４３の前端面には後述する取付部材４８を挿入可能な切り欠き４５が設けられており、該切り欠き４５には挿入された取付部材４８を保持する保持片４６、４６が下方へと突設されている。さらに、切り欠き４５の後方には、係止突起４７が下方へと突設されている。 FIG. 7 is an explanatory view showing an attachment structure using an attachment member 48 made of synthetic resin.
On the front side of the breaker 41, a fitting convex portion 42 is integrally projected, and a locking concave portion (not shown) is provided on the rear side. On the other hand, the mounting panel 43 is integrally provided with a hook-like locking claw 44 that locks in the locking recess. Further, a notch 45 into which a mounting member 48 to be described later can be inserted is provided on the front end surface of the mounting panel 43, and holding pieces 46, 46 for holding the inserted mounting member 48 are provided below the notch 45. Projected to Further, behind the cutout 45, a locking projection 47 projects downward.

取付部材４８は、弾性を有する合成樹脂により形成されたものであって、その先端には係止突起４７と係止する係止部４９が設けられており、基端にはブレーカ４１の嵌合凸部４２が嵌合可能な嵌合凹部５０が設けられている。
そして、ブレーカ４１の係止凹部に取付パネル４３の係止爪４４を係止させた状態で、切り欠き４５に取付部材４８を挿入する。そして、嵌合凸部４２を嵌合凹部５０に嵌合させるとともに、係止突起４７と係止部４９とを係止させて、ブレーカ４１を取付パネル４３に固定する。 The mounting member 48 is formed of an elastic synthetic resin, and a locking portion 49 that locks the locking projection 47 is provided at the distal end, and the breaker 41 is fitted at the proximal end. A fitting recess 50 into which the projection 42 can be fitted is provided.
Then, the mounting member 48 is inserted into the notch 45 with the locking claw 44 of the mounting panel 43 locked in the locking recess of the breaker 41. Then, the fitting convex portion 42 is fitted into the fitting concave portion 50, and the locking projection 47 and the locking portion 49 are locked to fix the breaker 41 to the mounting panel 43.

しかしながら、ねじを利用してブレーカを取り付けるとなると、ねじの締め付け等に手間や時間がかかり、組立費のコストアップ等につながる。特に、分岐ブレーカのように回路数が多い場合は尚更である。
また、弾性部材を利用するとなると、取付パネルに対するブレーカの取り付け作業は簡単になるものの、取付パネルに専用の弾性部材を設置しなければならない。したがって、部品点数の増加や弾性部材の設置に係る手間等からコストアップとなる。さらに、専用の取付部材を用いるとなると、弾性部材を利用する場合と同様、部品点数の増加といった問題が生じる上、取付パネルに対して煩雑な加工を施さなければならない等といったように更なるコストアップが要求されることになる。さらにまた、合成樹脂製の取付部材に設けられた係止部とブレーカに設けられた係止突起との係止等によりブレーカを固定するため、ブレーカの取り付け後にガタつきが発生しやすいといった問題も抱えている。加えて、ガタつきが発生し、ねじによる固定に変更したい際には、ブレーカと取付パネルとの両方をねじ専用のものに交換しなければならない。したがって、取付パネルにブレーカを複数取り付けているような場合には、ガタつきが発生していないブレーカも含めてその全てを交換する必要があったり、交換したい箇所の取付パネルを煩雑な作業により切り取って交換する等極めて使い勝手が悪い。 However, if the breaker is attached using screws, it takes time and effort to tighten the screws, leading to an increase in assembly costs. This is especially true when the number of circuits is large, such as a branch breaker.
If an elastic member is used, the breaker can be easily attached to the mounting panel, but a dedicated elastic member must be installed on the mounting panel. Therefore, the cost increases due to the increase in the number of parts and the labor involved in installing the elastic member. Furthermore, if a dedicated mounting member is used, as with the case of using an elastic member, problems such as an increase in the number of parts occur, and the mounting panel must be subjected to complicated processing. Up is required. Furthermore, since the breaker is fixed by locking the locking portion provided on the synthetic resin mounting member and the locking protrusion provided on the breaker, there is a problem that rattling is likely to occur after the breaker is mounted. I have it. In addition, when rattling occurs and it is desired to change to fixing with screws, both the breaker and the mounting panel must be replaced with screws. Therefore, when multiple breakers are attached to the mounting panel, it is necessary to replace all of them, including those that do not rattle, or the mounting panel at the place where you want to replace is cut off by complicated work. It is very inconvenient to use.

そこで、本発明は、上記問題を解決すべくなされたものであって、ブレーカを簡単且つ確実に固定することができる上、コスト面においても有利で且つ合成樹脂製の部材同士の係合を利用した取り付け及びねじによる取り付けのどちらにも対応可能なブレーカ取付構造を提供しようとするものである。   Therefore, the present invention has been made to solve the above-described problem, and can easily and reliably fix the breaker, and is advantageous in terms of cost and uses the engagement between the members made of synthetic resin. Therefore, it is an object of the present invention to provide a breaker mounting structure that can be applied to both mounting and screw mounting.

Further, the fixed hook 11 is erected and fitted to the fitting convex portion 5, so that the sliding movement of the breaker 1 in the front-rear direction on the mounting panel 2 is locked, and the breaker 1 is fixed. When the fixed hook 11 is raised to the standing position, the locking step portion 15 provided on the shaft portion 14 is locked to the front end (folded portion) of the mounting panel 2. Further, when it is desired to remove the breaker 1, the fixed hook 11 may be tilted.

一方、固定フック１１を用いた嵌着による取り付けではブレーカ１にガタつきが発生した場合や、より確実（強固）に固定したい場合等には、ねじ１６を用いてブレーカ１を取り付けることも可能である。
そこで、ねじ１６を用いたブレーカ１の取付構造について、図４及び５を基に説明する。図４（ａ）は、ねじ１６によりブレーカ１を取付パネル２’に取り付ける様子を示す説明斜視図であり、図４（ｂ）は、ブレーカ１を取り付けた状態を示す説明斜視図である。また、図５（ａ）は、ねじ１６によりブレーカ１を取付パネル２’に取り付ける様子を示す説明断面図であり、図５（ｂ）は、ブレーカ１の底面を示す説明図である。 On the other hand, when the breaker 1 is loosely attached by the attachment using the fixing hook 11 or when it is desired to fix the breaker 1 more securely (strongly), the breaker 1 can be attached using the screw 16. is there.
Therefore, the mounting structure of the breaker 1 using the screw 16 will be described with reference to FIGS. FIG. 4A is an explanatory perspective view showing a state in which the breaker 1 is attached to the attachment panel 2 ′ with the screw 16. FIG. 4B is an explanatory perspective view showing a state in which the breaker 1 is attached. FIG. 5A is an explanatory cross-sectional view showing a state in which the breaker 1 is attached to the attachment panel 2 ′ with the screw 16, and FIG. 5B is an explanatory view showing the bottom surface of the breaker 1.

ねじ１６による取り付けを行う場合、図４及び５に示す如く、ブレーカ１において、取付片３は、ねじ止め部７側を前方へ突出させた状態とされる。ねじ止め部７には、ねじ１６を挿入可能な挿入孔８が穿設されている。   When mounting with the screw 16, as shown in FIGS. 4 and 5, in the breaker 1, the mounting piece 3 is in a state in which the screwing portion 7 side protrudes forward. An insertion hole 8 into which a screw 16 can be inserted is formed in the screwing portion 7.

また、ねじ１６による取り付けを行う場合、取付パネル２’が用いられる。取付パネル２’は、薄板状に形成された金属板であって、取付パネル２同様、ブレーカ１の底面に設けられた係止片６を嵌入可能な係止孔１２が穿設されている。加えて、ブレーカ１の係止片６を係止孔１２に係止させた状態において、取付片３の挿入孔８に対応する位置には、ねじ１６を挿通可能な挿通孔１７が穿設されている。尚、このような係止孔１２及び挿通孔１７を一組としたブレーカ１の取付機構は、取付パネル２’の左右方向に複数組設けられている。   Further, when the attachment with the screw 16 is performed, the attachment panel 2 'is used. The mounting panel 2 ′ is a metal plate formed in a thin plate shape, and, like the mounting panel 2, a locking hole 12 into which a locking piece 6 provided on the bottom surface of the breaker 1 can be fitted is formed. In addition, when the locking piece 6 of the breaker 1 is locked to the locking hole 12, an insertion hole 17 through which the screw 16 can be inserted is formed at a position corresponding to the insertion hole 8 of the mounting piece 3. ing. Note that a plurality of sets of attachment mechanisms for the breaker 1 including the locking holes 12 and the insertion holes 17 as a set are provided in the left-right direction of the mounting panel 2 ′.

ここで、ブレーカ１を取付パネル２’に取り付ける方法について説明する。
まず、図３に示す如く、取付片３を回動させ、ねじ止め部７を前方へと突出させた状態とする。そして、ブレーカ１の係止片６を取付パネル２’の所定の係止孔１２に嵌入させるとともに、嵌入状態にてブレーカ１を後方へとスライドさせ、係止片６を係止孔１２に係止させる。該係止により、挿入孔８と挿通孔１７とが対応するように位置決めされる。そこで、ねじを挿入孔８から挿入して取付パネル２’に螺着することによって、ブレーカ１の取付パネル２’上での前後方向へのスライド移動がロックされ、ブレーカ１は所定位置にて固定される。 Here, a method of attaching the breaker 1 to the attachment panel 2 ′ will be described.
First, as shown in FIG. 3, the mounting piece 3 is rotated and the screwing portion 7 is projected forward. Then, the locking piece 6 of the breaker 1 is fitted into the predetermined locking hole 12 of the mounting panel 2 ′, and the breaker 1 is slid rearward in the fitted state, and the locking piece 6 is engaged with the locking hole 12. Stop. By the locking, the insertion hole 8 and the insertion hole 17 are positioned so as to correspond to each other. Therefore, by inserting a screw from the insertion hole 8 and screwing it onto the mounting panel 2 ′, the sliding movement of the breaker 1 in the front-rear direction on the mounting panel 2 ′ is locked, and the breaker 1 is fixed at a predetermined position. Is done.

以上のようなブレーカ１の取付構造によれば、ブレーカ１に、一方側に嵌合凸部５を、他方側に挿入孔８を有するねじ止め部７をそれぞれ設けてなる取付片３を軸９を中心として回動可能に設けている。そして、図３に示すような回動操作によって、嵌合凸部５又はねじ止め部７のいずれかをブレーカ１の前面から前方へと突出した状態とすることができる。したがって、合成樹脂部材同士の嵌合・嵌着を利用した簡易な取り付けを行いたい場合、及びねじ１６による確実な取り付けを行いたい場合のどちらにも対応することができる。すなわち、状況に応じて作業現場で固定方法を選択することができ、極めて汎用性が高い上、取付態様に応じて専用の構造を備えたブレーカをそれぞれ用意する必要がないため、ブレーカ１の固定にかかる手間やコストを抑えることができる。
また、取付片３を、ブレーカ１に設けられた収納空間１０内に設置しており、取付片３の取り付けに使用しない側を収納空間１０内に収納するような構成としているため、取付パネル２、２’上にブレーカ１を隣接して複数取り付ける場合であっても、取付片３が邪魔になることはない。その上、取付片３の不用意な破損等を防止することもできる。 According to the mounting structure of the breaker 1 as described above, the mounting piece 3 formed by providing the breaker 1 with the fitting convex portion 5 on one side and the screwing portion 7 having the insertion hole 8 on the other side is provided on the shaft 9. Is provided so as to be rotatable around the center. And either the fitting convex part 5 or the screwing part 7 can be made into the state protruded ahead from the front surface of the breaker 1 by rotation operation as shown in FIG. Therefore, it is possible to cope with either simple attachment utilizing fitting / fitting of synthetic resin members or reliable attachment with the screw 16. In other words, the fixing method can be selected at the work site according to the situation, and since it is extremely versatile, it is not necessary to prepare each breaker with a dedicated structure according to the mounting mode. Can save time and cost.
Further, since the mounting piece 3 is installed in the storage space 10 provided in the breaker 1 and the side not used for mounting the mounting piece 3 is configured to be stored in the storage space 10, the mounting panel 2 Even when a plurality of breakers 1 are mounted adjacently on 2 ′, the mounting piece 3 does not get in the way. In addition, inadvertent damage to the mounting piece 3 can be prevented.

さらに、固定フック１１による取り付けを行うにあたっては、取付パネル２に設置された固定フック１１を起立させ、嵌合凸部５に嵌合させれば、ブレーカ１を固定することができる。一方、ブレーカ１を取り外したい場合には、固定フック１１を傾倒させればよい。すなわち、固定フック１１を起立させたり傾倒させたりするだけで、ブレーカ１の固定及び取り外しを行うことができるため、ブレーカ１を簡単な作業で且つ確実に取付パネル２に固定することができる。
さらにまた、固定フック１１を備える場合、取付パネル２の前端縁を下方へと湾曲するように形成することができる。このような構成とすることにより、取付パネル２の前端側がブレーカ１の二次側へ出っ張らないため、二次側接続端子４ｂ、４ｂへの電線結線等の邪魔とならないし、パネル前端により電線等を傷つける心配もない。 Further, when mounting with the fixing hook 11, the breaker 1 can be fixed by raising the fixing hook 11 installed on the mounting panel 2 and fitting it with the fitting convex portion 5. On the other hand, when it is desired to remove the breaker 1, the fixing hook 11 may be tilted. That is, since the breaker 1 can be fixed and removed simply by raising or tilting the fixing hook 11, the breaker 1 can be fixed to the mounting panel 2 with a simple operation.
Furthermore, when the fixing hook 11 is provided, the front edge of the mounting panel 2 can be formed to bend downward. By adopting such a configuration, the front end side of the mounting panel 2 does not protrude to the secondary side of the breaker 1, so that it does not obstruct the wire connection to the secondary side connection terminals 4b, 4b, etc. There is no worry about hurting.

またさらに、取付パネル２の湾曲部に窓部１３を設けるとともにその前端を後方へと折り曲げる一方、固定フック１１を窓部１３から前方へと突出するように設けることにより、固定フック１１の軸部１４を湾曲部内側にて支持することができる。したがって、取付パネル２に複雑な支持機構等を設けることなく、固定フック１１をスムーズに回動可能に支持することができる。
加えて、固定フック１１の軸部１４に係止段部１５を設け、固定フック１１が起立位置（嵌着状態）にある際に、係止段部１５と取付パネル２の前端とが係止するように構成しているため、起立位置を超えて固定フック１１を回動させてしまい、固定フック１１が破損してしまうといった事故等を防止することができる。 Further, the window portion 13 is provided in the curved portion of the mounting panel 2 and the front end thereof is bent backward, while the fixing hook 11 is provided so as to protrude forward from the window portion 13, thereby 14 can be supported inside the curved portion. Therefore, the fixing hook 11 can be smoothly supported without being provided with a complicated support mechanism or the like on the mounting panel 2.
In addition, a locking step portion 15 is provided on the shaft portion 14 of the fixed hook 11, and when the fixed hook 11 is in the standing position (fitted state), the locking step portion 15 and the front end of the mounting panel 2 are locked. Therefore, it is possible to prevent an accident or the like that the fixed hook 11 is rotated beyond the standing position and the fixed hook 11 is damaged.

また、ブレーカ１の取付態様に拘わらず、ブレーカ１の底面に設けられた係止片６を、取付パネル２に設けられた係止孔１２に嵌入させ、該嵌入状態にてブレーカ１を後方へとスライドさせることにより、ブレーカ１を係止状態にて所定の位置に設置することができる。したがって、取付パネル２に対するブレーカ１の固定を極めて確実なものとすることができる。
さらに、ねじ１６を用いた取り付けを行う場合にあっては、係止片６による係止により、取付片３の挿入孔８と取付パネル２の挿通孔１７とが自然と対応する位置に位置決めされるため、組立作業を極めてスムーズに行うことができる。 Regardless of the manner in which the breaker 1 is mounted, the locking piece 6 provided on the bottom surface of the breaker 1 is fitted into the locking hole 12 provided in the mounting panel 2, and the breaker 1 is moved rearward in the fitted state. The breaker 1 can be installed at a predetermined position in a locked state. Therefore, the breaker 1 can be fixed to the mounting panel 2 very reliably.
Furthermore, when mounting using the screw 16, the insertion hole 8 of the mounting piece 3 and the insertion hole 17 of the mounting panel 2 are positioned at positions corresponding to each other naturally by the locking by the locking piece 6. Therefore, the assembly work can be performed very smoothly.

なお、本発明のブレーカ取付構造に係る構成は、上記実施形態の態様に何ら限定されるものではなく、本発明の趣旨を逸脱しない範囲で、必要に応じて適宜変更することができる。   In addition, the structure which concerns on the breaker mounting structure of this invention is not limited to the aspect of the said embodiment at all, It can change suitably as needed in the range which does not deviate from the meaning of this invention.

たとえば、上記実施の形態では、一次側がプラグ形式（銅バーを挟むように一次側接続端子を差し込む形式）であるため、取付片を銅バー等の邪魔とならないよう二次側接続端子側に設けているが、取付片の設置位置は適宜変更可能であるし、複数の取付片を設けるような構成としても何ら問題はない。
また、取付片の回動方向についても、上記実施の形態では、左右方向を軸として上下方向に回動するものといるが、上下方向を軸に水平回動するような構成としてもよい。加えて、一の取付片に嵌合凸部とねじ止め部とを設けるのではなく、それぞれの機能部を有する二の取付片を、ブレーカから任意に突出可能に設けるような構成とすることも可能である。 For example, in the above embodiment, since the primary side is a plug type (a type in which the primary side connection terminal is inserted so as to sandwich the copper bar), the mounting piece is provided on the secondary side connection terminal side so as not to obstruct the copper bar or the like. However, the installation position of the mounting piece can be changed as appropriate, and there is no problem even if a plurality of mounting pieces are provided.
Also, with regard to the rotation direction of the mounting piece, in the above-described embodiment, the mounting piece rotates in the vertical direction about the left-right direction. However, the mounting piece may be configured to rotate horizontally about the vertical direction. In addition, instead of providing a fitting convex part and a screwing part on one mounting piece, it is also possible to provide a structure in which two mounting pieces having respective functional parts are provided so as to be able to arbitrarily protrude from the breaker. Is possible.

さらに、ブレーカ側から突設した凸部に嵌合・係合する構成であれば、固定フックの形状やその設置に係る構造等も適宜変更可能である。一方、固定フックを有する取付パネルの前端縁の形状も適宜設計変更可能で、上記実施の形態の如く湾曲させた後に折り曲げるものに限られず、その前端が後方または上方を向くまで湾曲させてもよいし、湾曲部や折り曲げ部等を設けなくともよい。また、ブレーカの底面に設けた係止片の数も上記実施の形態に記載のものに何ら限定されることはなく、取付パネルにブレーカを位置決めするような凸部・突片を（必要であれば、ブレーカ側に凹部を）設けるようにしてもよい。加えて、フックピンやねじによる固定のみで十分な場合には、係止片等の構成を設けなくともよい。   Furthermore, if it is the structure which fits and engages with the convex part protrudingly provided from the breaker side, the shape of a fixed hook, the structure concerning the installation, etc. can be changed suitably. On the other hand, the shape of the front end edge of the mounting panel having the fixing hook can be changed as appropriate, and is not limited to the one that is bent after being bent as in the above embodiment, but may be bent until the front end faces rearward or upward. However, it is not necessary to provide a curved portion or a bent portion. Further, the number of the locking pieces provided on the bottom surface of the breaker is not limited to the one described in the above embodiment, and a convex part / projection piece for positioning the breaker on the mounting panel (if necessary) For example, a recess may be provided on the breaker side).
