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を基に説明する。
図6(a)は、ねじ35を利用したブレーカ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が凹設されている。一方、取付パネル33には、ブレーカ31の係止凹部32、32に係止可能な鉤状の係止爪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 a breaker mounting structure using a screw 35, and locking recesses 32, 32 are formed in the base of the breaker 31. On the other hand, hook-like locking claws 34, 34 that can be 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 of the locking claws 34 with the screw 35 in a state where the locking claws 34 are locked in the locking recesses 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を利用したブレーカ取付構造を示す説明図であって、上記構造において取付パネル33に設けられている一方の係止爪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、係止爪34を一方の係止凹部32に係止させた状態でブレーカ31を上方から押し込めば、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 breaker mounting structure using a dedicated elastic member 36. In the above structure, one locking claw 34 provided on the mounting panel 33 is locked with a locking projection. The elastic member 36 is provided. Therefore, if the breaker 31 is pushed in from above while the locking claw 34 is locked to the one locking recess 32, the locking projection of the elastic member 36 and the locking recess 32 of the breaker 31 are locked, The breaker 31 is fixed to the mounting panel 33.

図7は、合成樹脂製の取付部材48を利用したブレーカ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、図示しない係止凹部が設けられている。また、取付パネル43には、係止凹部に係止可能な鉤状の係止爪44が一体的に突設されている。さらに、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L字状の保持片46、46が下方へと突設されている。加えて、取付パネル43の裏面側で、且つ、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 a breaker mounting structure using a mounting member 48 made of synthetic resin.
On the front side of the breaker 41, a fitting convex portion 42 is integrally projected, and on the back side, a locking concave portion (not shown) is provided. The mounting panel 43 is integrally provided with a hook-shaped locking claw 44 that can be locked 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 an L-shaped holding piece for holding the inserted mounting member 48 is provided in the notch 45. 46 and 46 project downward. In addition, a locking projection 47 protrudes downward on the back side of the mounting panel 43 and behind the notch 45.

一方、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、切り欠き45への挿入状態にて係止突起47と係止する係止部49が設けられている。また、基端には、切り欠き45への挿入状態にてブレーカ41の嵌合凸部42が嵌合する嵌合凹部50が設けられている。   On the other hand, the mounting member 48 is formed of an elastic synthetic resin, and a locking portion 49 that locks the locking protrusion 47 in the inserted state into the notch 45 is provided at the tip thereof. ing. The base end is provided with a fitting recess 50 into which the fitting protrusion 42 of the breaker 41 is fitted in the state of being inserted into the notch 45.

上述の如き構成を有するブレーカ取付構造によれば、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、嵌合凸部42が嵌合凹部50に嵌合するとともに係止突起47と係止部49とが係止するまで、取付部材48を切り欠き45へと挿入することによって、ブレーカ41を取付パネル43に固定する。   According to the breaker mounting structure having the above-described configuration, the fitting convex portion 42 is fitted into the fitting concave portion 50 in a state where the locking claw 44 of the mounting panel 43 is locked to the locking concave portion of the breaker 41. At the same time, the breaker 41 is fixed to the mounting panel 43 by inserting the mounting member 48 into the notch 45 until the locking projection 47 and the locking portion 49 are locked.

しかしながら、ねじを利用してブレーカを固定するとなると、ねじの締め付け等に手間や時間がかかることから、組立費のコストアップ等の要因となる。特に、分岐ブレーカのように回路数が多い場合には、固定するブレーカの数も多くなり、尚更である。また、弾性部材を用いた固定構造では、ブレーカの取付パネルへの取り付け作業自体は簡易となるものの、取付パネルに専用の弾性部材を設けなければならない。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、弾性部材を利用する場合以上に取付パネルに対して複雑な加工を施さなければならない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、取付部材を用いた固定構造では、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ある。加えて、ガタつきが生じたことから、ねじによる固定に変更したい場合には、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、取付パネルに複数のブレーカを取り付けているような場合には、ガタつきが生じていないブレーカも含めてその全てを交換する必要性があったり、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しなければならないといったように使い勝手の点においても問題を抱えている。
However, if the breaker is fixed using screws, it takes time and effort to tighten the screws, which causes an increase in assembly costs. In particular, when the number of circuits is large as in the case of a branch breaker, the number of breakers to be fixed increases, and so on. Further, in the fixing structure using the elastic member, although the work of attaching the breaker to the mounting panel itself becomes simple, a dedicated elastic member must be provided 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, problems such as an increase in the number of parts occur as in the case of using an elastic member, and the mounting panel must be processed more complicatedly than when an elastic member is used. There is a need for further cost increases such as inevitable. Furthermore, in the fixing structure using the mounting member, since the breaker is fixed by locking the locking portion provided on the mounting member and the locking projection provided on the breaker, rattling occurs after the breaker is mounted. There is also the problem of being easy to do. In addition, since rattling has occurred, if it is desired to change to fixing with screws, both the breaker and the mounting panel must be replaced with ones dedicated to screws. Therefore, when multiple breakers are attached to the mounting panel, it is necessary to replace all of them, including the breakers that do not rattle. There is also a problem in terms of usability, such as having to cut and replace.

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、コスト面においても有利である上、合成樹脂部材等を用いた係合による簡易な取り付け及びねじによる確実な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, which is advantageous in terms of cost, and by engagement using a synthetic resin member or the like. It is an object of the present invention to provide a breaker mounting structure that can handle both simple mounting and secure mounting with screws.

Therefore, by inserting the screw 20 from the screwing 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. can do.

一方、より簡易な取り付けで良い場合等には、係合爪6を利用してブレーカ1を取付パネル2に取り付けることも可能となっている。
そこで、係合爪6によりブレーカ1を取付パネル2に取り付ける方法について、図2〜5を基に説明する。図4(a)は、係合爪6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した斜視説明図であり、図4(b)は、ブレーカ1を取り付けた状態を示した斜視説明図である。また、図5は、ブレーカ1を取り付ける際の係合爪6の状態を示した説明図である。
On the other hand, the breaker 1 can be attached to the attachment panel 2 using the engaging claws 6 when simpler attachment is sufficient.
Therefore, a method for attaching the breaker 1 to the attachment panel 2 with the engaging claws 6 will be described with reference to FIGS. 4A is a perspective explanatory view showing a state in which the breaker 1 is attached to the mounting panel 2 by the engaging claws 6, and FIG. 4B is a perspective explanatory view showing a state in which the breaker 1 is attached. is there. FIG. 5 is an explanatory view showing a state of the engaging claw 6 when the breaker 1 is attached.

まず、取付片3を回転させて、図2に示す如く係合部5を機能位置に位置させる。係合部5が機能位置に位置すると、図5等に示す如く係合爪6がブレーカ1の底面から下方へと突出した状態となる。次に、ブレーカ1の掛止片11、11を所定の掛止孔14、14に嵌入させる。該嵌入状態にあっては、図5(a)に示す如く、ブレーカ1の底面から突出する係合爪6が取付パネル2の上面に押し付けられるとともにねじ止め部7が当接段部16に押し当てられるため、係合部5がその弾性により上方へと撓んだ状態となる。
そして、該嵌入状態にてブレーカ1を後方へとスライドさせ、各掛止片11を掛止孔14に掛止させると、係合爪6が前側の掛止孔14に嵌着する。つまり、図5(b)に示す如く、弾性力により係合爪6が上記撓み状態から下方に突出する通常状態へと復帰し、前側の掛止孔14の前縁に係合する。したがって、取付パネル2上でのブレーカ1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。尚、ブレーカ1を取り外したい際には、係合爪6を後方へと撓ませるとともに上方へと押し上げ、係合爪6と掛止孔14との係合を解除すれば、ブレーカ1は前方へとスライド可能となる。
First, the attachment piece 3 is rotated to place the engaging portion 5 in the functional position as shown in FIG. When the engaging portion 5 is located at the functional position, the engaging claw 6 protrudes downward from the bottom surface of the breaker 1 as shown in FIG. Next, the latching pieces 11 and 11 of the breaker 1 are fitted into predetermined latching holes 14 and 14. In the inserted state, as shown in FIG. 5A, the engaging claw 6 protruding from the bottom surface of the breaker 1 is pressed against the upper surface of the mounting panel 2 and the screwing portion 7 is pressed against the contact step portion 16. Therefore, the engaging portion 5 is bent upward due to its elasticity.
Then, when the breaker 1 is slid rearward in the fitted state and each latching piece 11 is latched in the latching hole 14, the engaging claw 6 is fitted in the latching hole 14 on the front side. That is, as shown in FIG. 5 (b), the engaging claw 6 returns from the bent state to the normal state protruding downward by the elastic force, and engages with the front edge of the front retaining hole 14. Therefore, 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. When the breaker 1 is desired to be removed, the breaker 1 is moved forward by bending the engagement claw 6 backward and pushing it upward to release the engagement between the engagement claw 6 and the latch hole 14. And slide.

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、一方側に係合部5を、他方側にねじ止め部7を夫々設けてなる取付片3を軸部9、9により回転可能に設けている。そして、図2に示すような回転操作によって、係合部5又はねじ止め部7のうちのいずれか一方をブレーカ1の収納空間10から突出した機能位置へと位置させることができる。したがって、弾性を有する合成樹脂部材による簡易な取り付けを行いたい場合、及びねじ20を用いた確実な取り付けを行いたい場合のどちらにもブレーカ1及び取付パネル2を交換することなく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、汎用性が極めて高い上、取付態様に応じて専用の構造を備えたブレーカや取付パネルを夫々用意したり交換したりする必要がなく、手間やコストを極力抑えることができる。加えて、取付パネル2やブレーカ1本体に特殊な加工を施す必要がないことから、ブレーカ1や取付パネル2を低コストで簡易に製造することができる。
また、取付片3を、ブレーカ1に設けた収納空間10内に設置しており、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上に複数のブレーカ1、1・・を隣接して取り付けるような場合であっても、取付片3が邪魔になることはないし、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 engaging portion 5 on one side and the screwing portion 7 on the other side can be rotated by the shaft portions 9 and 9. Provided. And either one of the engaging part 5 or the screwing part 7 can be located in the functional position which protruded from the storage space 10 of the breaker 1 by rotation operation as shown in FIG. Therefore, it is possible to cope with both the case where simple attachment using the elastic synthetic resin member is desired and the case where reliable attachment using the screw 20 is desired without exchanging the breaker 1 and the attachment panel 2. . In other words, the fixing method can be selected at the work site according to the situation, it is extremely versatile, and it is necessary to prepare and replace breakers and mounting panels with a dedicated structure according to the mounting mode. There is no problem, and labor and cost can be minimized. In addition, since it is not necessary to apply special processing to the mounting panel 2 and the breaker 1 main body, the breaker 1 and the mounting panel 2 can be easily manufactured at low 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 is stored in the storage space 10, a plurality of breakers are mounted on the mounting panel 2. Even when 1, 1,... Are attached adjacently, the attachment piece 3 does not get in the way, and inadvertent damage to the attachment piece 3 can be prevented.

さらに、係合部5側での係合によりブレーカ1を取り付ける場合には、係合部5を機能位置に位置させた状態で、掛止片11、11を掛止孔14、14に嵌入させた後、ブレーカ1を後方へとスライドさせるだけでよい。つまり、非常に簡易な操作でブレーカ1を取付パネル2に取り付けることができ、使い勝手が良い。さらにまた、取付片3を、弾性を有する合成樹脂により形成しているため、掛止片11、11を掛止孔14、14に嵌入させた際、係合爪6が上方へと撓んだ状態となる。したがって、ブレーカ1の後方へのスライド動作の支障にならない上、所定の掛止位置までスライドさせれば、係合部5の弾性力によって係合爪6が自動的に前側の掛止孔14に嵌入して掛止孔14の前縁に係合するため、取り付け作業を行うにあたって工具等を準備する必要が全くなく、極めて簡易な作業で取り付けを行うことができる。尚、ブレーカ1を取り外す場合にも、係合爪6を後方へと撓ませるとともに上方へと押し上げて、掛止孔14との係合状態を解除するだけでよく、何ら工具を必要としない。   Further, when the breaker 1 is attached by engagement on the engaging portion 5 side, the latching pieces 11 and 11 are fitted into the latching holes 14 and 14 with the engaging portion 5 positioned at the functional position. After that, it is only necessary to slide the breaker 1 backward. That is, the breaker 1 can be attached to the attachment panel 2 by a very simple operation, and it is easy to use. Furthermore, since the mounting piece 3 is made of a synthetic resin having elasticity, when the latching pieces 11 and 11 are fitted into the latching holes 14 and 14, the engaging claw 6 is bent upward. It becomes a state. Therefore, the sliding movement of the breaker 1 to the rear is not hindered, and if the sliding is performed to a predetermined latching position, the engagement claw 6 is automatically moved to the front latching hole 14 by the elastic force of the engagement portion 5. Since it is inserted and engaged with the front edge of the retaining hole 14, it is not necessary to prepare a tool or the like when performing the mounting operation, and the mounting can be performed with an extremely simple operation. Even when the breaker 1 is removed, it is only necessary to bend the engaging claw 6 backward and push it upward to release the engagement state with the retaining hole 14, and no tool is required.

またさらに、上記係合部5側での係合による取り付けではガタつきが生じる等の場合には、取付片3を回転操作してねじ止め部7を機能位置とし、ねじ20を用いて取り付ければよい。そして、ねじ20を用いた取り付けを行う場合、掛止片11、11を掛止孔14、14に嵌入させてブレーカ1を後方へとスライドさせれば、取付片3のねじ孔8と取付パネル2の丸孔15とが自然と対応する位置に位置決めされるため、取り付け作業を極めてスムーズに行うことができる。
加えて、取付片3の係合部5にはつまみ片13を、ねじ止め部7には突片12を夫々設けており、どちらも機能位置に位置した際にブレーカ1の前方へと突出するように設けているため、より容易に取付片3を回転操作することができる。また、取付片3も工具を用いることなくブレーカ1に着脱可能としている。したがって、たとえ取付片3が破損したとしても、取付片3のみを容易に交換することができるため、ブレーカ全体を交換しなければならないものと比較して、上記事態に迅速に対応可能である上、コスト面においても有利である。
Still further, in the case where rattling occurs due to the engagement by the engagement portion 5 side, the attachment piece 3 is rotated to make the screwing portion 7 a functional position and attached using the screw 20. Good. And when attaching using the screw 20, if the latching pieces 11 and 11 are inserted in the latching holes 14 and 14 and the breaker 1 is slid back, the screw hole 8 of the mounting piece 3 and the mounting panel Since the two round holes 15 are naturally positioned at the corresponding positions, the attaching operation can be performed very smoothly.
In addition, a knob piece 13 is provided on the engaging portion 5 of the mounting piece 3 and a projecting piece 12 is provided on the screwing portion 7, respectively, and both protrude to the front of the breaker 1 when positioned at the functional position. Thus, the mounting piece 3 can be rotated more easily. Further, the attachment piece 3 is also detachable from the breaker 1 without using a tool. Therefore, even if the mounting piece 3 is damaged, only the mounting piece 3 can be easily replaced. Therefore, compared to the case where the entire breaker must be replaced, the above situation can be dealt with quickly. This is also advantageous in terms of cost.

In addition, it is possible to adopt a configuration in which two attachment pieces having respective functions are provided so as to be arbitrarily protrudeable from the breaker, instead of providing the engagement part and the screwing part on one attachment piece. is there.

さらに、上記実施形態では、係合爪を掛止孔に係合させるような構成としているが、係合爪を丸孔に係合させるように構成しても何ら問題はない。その際、係合爪を有する係合部の機能位置を、ねじ止め部と同様、ブレーカの前方へと突出する位置とすることは当然可能である。
加えて、掛止片や掛止孔の数や大きさ、形状等も適宜変更可能であって、上記実施形態の如くブレーカの底面の前後に一対の掛止片を設けるのではなく、前側或いは後側のどちらかに一つ設けるような構成としてもよいし、係合部による係合やねじによる螺着のみで十分確実に固定可能である場合には、掛止片等を設けなくともよい。また、掛止片を取付パネルに、掛止孔をブレーカに設けることも可能である。
Furthermore, in the said embodiment, it is set as the structure which engages an engaging claw with a latching hole, However There is no problem even if it comprises so that an engaging claw may be engaged with a round hole.
