【発明が属する技術分野】
本発明は、各種電子機器を収納する電子機器の筐体接合構造に関する。
【0002】
【従来の技術】
従来、この種の筐体として、底面板と側面板を備えた筐体が知られており、2つの側面板を備える筐体では、底面板の隣合う2辺を上方に屈曲して側面板を形成したものがある。そして、このような筐体が、振動雰囲気や衝撃雰囲気中に晒され、側面板の厚さ方向に振動や衝撃を受けると、折曲部分を中心として側面板が振動し、側面板が変形したり、その折曲部分に亀裂が発生し、耐久性を損ねるという問題があった。
【0003】
そこで、これを防止するため、一般的には、隣合う側面板の縁を重ね合わせ、この重ね合わせた縁相互をビス止め等により接合する構造が用いられている。しかし、このような接合構造では、ビス止めを行うために、組立に必要な部品点数が増加すると共に、製作工数が増加するという問題がある。
【0004】
そこで、本発明は、振動や衝撃に対して強度的に優れ、組立てが容易な電子機器の筐体接合構造を提供することを目的とする。
【0005】
【課題を解決するための手段】
請求項1の発明は、隣合う一方と他方の側面板の縁部を接合する電子機器の筐体接合構造において、電子機器が取付けられる底面板の隣り合う二辺を、該底面板の厚さ方向一側に略90度に屈曲して前記一方と他方の側面板を前記底面板と一体に形成し、前記一方と他方の側面板と底面板との間には屈曲部が形成され、前記他方の側面板を前記一方の側面板より長く形成し、前記一方の側面板の縁部に係合部を設けると共に、前記他方の側面板の縁部に前記係合部を挟持する挟持部を設け、前記係合部は、前記一方の側面板の縁部に設けた突出片を前記他方の側面板側に屈曲形成してなり、前記挟持部は、前記突出片の外面に当接する前記他方の側面板の縁部の内面と、前記他方の側面板の縁部の一部を内側に屈曲すると共に外面が前記突出片の内面に当接する屈曲片とからなり、前記突出片を前記他方の側面板と前記屈曲片とにより抜け止め状態で挟着したものであり、挟持部が係合部を両側から挟むため、挟持部を設けた他方の面板は、その厚さ方向の一側及び他側に振れ止めされた構造となる。
【0006】
また、屈曲片と他方の面板の縁部と間に係合部を挟持するから、突出片の他側面に当接する屈曲片を加工するだけで、挟持部が得られる。さらに、突出片を他方の側面板と屈曲 片により抜け止め状態で挟着することにより、一方の側面板における屈曲部を中心とした振動を防止することができる。
【0007】
【発明の実施形態】
以下、本発明の実施例を添付図面を参照して説明する。図1ないし図3は本発明の一実施例を示し、筐体1はアルミニウムなどの金属材料からなり、底面板2の隣合う二辺を、該底面板2の厚さ方向一側にほぼ90度に屈曲形成して一方及び他方の側面板3,4を一体に形成し、これら側面板3,4と前記底面板2との間には折曲部5,6が形成される。そして、この例では、面板たる他方の側面板4を、面板たる一方の側面板3より長く形成している。また、面板たる前記底面板2には、図示しない電源等の電子機器が取付けられる。
【0008】
前記一方の側面板3の縁部3Fに、係合部たる突出片7を一体に設け、この突出片7を前記他方の側面板4側にほぼ90度に屈曲する。また、前記突出片7の外面7Gは、前記他方の側面板4の内面4Nに当接する。前記他方の側面板4の縁部4Fに長さ方向の切欠溝8,8を一対形成すると共に、この切欠溝8,8に挟まれた縁4F部分を内面側に切り起すようにして屈曲し、屈曲片9を形成し、この屈曲片9の先端側を前記他方の側面板4と平行に形成する。この屈曲片9の先端側の外面9Gは前記突出片7の内面7Nに当接し、前記他方の側面板4と前記屈曲片9により前記突出片7を挟持する。そして、前記他方の側面部4と前記屈曲片9により挟持部10を構成し、この挟持部10は側面部4の上方に形成されている。また、前記突出片7を前記他方の側面板4と前記屈曲片9により抜け止め状態で挟着することが好ましい。尚、図中11は、前記他方の側面板4の縁部4Fに形成した切欠であり、固定用や取付用のねじ(図示せず)が係合する。
【0009】
このように本実施例では、請求項1に対応して、隣合う一方と他方の側面板3,4の縁部3F,4Fを接合する電子機器の筐体接合構造において、底面板2の隣り合う二辺を、該底面板2の厚さ方向一側に略90度に屈曲して一方と他方の側面板3,4を底面板2と一体に形成し、一方と他方の側面板3,4と底面板2との間には屈曲部5,6が形成され、他方の側面板4を一方の側面板3より長く形成し、一方の側面板3の縁部3Fに係合部たる突出片7を設けると共に、他方の側面板4の縁部4Fに突出片7を挟持する挟持部10を設け、係合部は、一方の側面板3の縁部3Fに設けた突出片7を他方の側面板4側に屈曲形成してなり、挟持部10は、突出片7の外面7Gに当接する他方の側面板4の内面4Nと、他方の側面板4の縁部4Fの一部を内側に屈曲すると共に外面4Gが突出片7の内面7Nに当接する屈曲片9とからなり、突出片7を他方の側面板4と屈曲片9により抜け止め状態で挟着したものであるから、挟持部10が突出片4を両側から挟むため、挟持部10を設けた他方の側面板4は、その厚さ方向の一側及び他側に振れ止めされた構造となり、振動や衝撃を受けても、他方の側面板4が屈曲部5を中心として振動することがなく、振動や衝撃に対して優れた構造が得られる。
【0010】
また、突出片7の内面側または外面側に当接する屈曲片9を加工するだけで、挟持部10を得ることができ、その加工を容易に行うことができる。
【0011】
さらに、前記突出片7を前記他方の側面板4と前記屈曲片9により抜け止め状態で挟着することにより、一方の側面板3における屈曲部5を中心とした振動を防止することができる。また、屈曲片9を内面側に形成したから、他方の側面部4の外面4Gに突出部分を形成する必要がない。さらに、屈曲片9は縁部4Fの一部を切り起したものであるから、その加工が容易である。
【0012】
尚、本発明は上記実施例に限定されるものではなく本発明の要旨の範囲内において種々の変形実施が可能である。
【0013】
【発明の効果】
請求項1の発明は、隣合う一方と他方の側面板の縁部を接合する電子機器の筐体接合構造において、電子機器が取付けられる底面板の隣り合う二辺を、該底面板の厚さ方向一側に略90度に屈曲して前記一方と他方の側面板を前記底面板と一体に形成し、前記一方と他方の側面板と底面板との間には屈曲部が形成され、前記他方の側面板を前記一方の側面板より長く形成し、前記一方の側面板の縁部に係合部を設けると共に、前記他方の側面板の縁部に前記係合部を挟持する挟持部を設け、前記係合部は、前記一方の側面板の縁部に設けた突出片を前記他方の側面板側に屈曲形成してなり、前記挟持部は、前記突出片の外面に当接する前記他方の側面板の縁部の内面と、前記他方の側面板の縁部の一部を内側に屈曲すると共に外面が前記突出片の内面に当接する屈曲片とからなり、前記突出片を前記他方の側面板と前記屈曲片とにより抜け止め状態で挟着したものであり、振動や衝撃に対して強度的に優れ、組立てが容易な電子機器の筐体接合構造を提供することができる。

[Technical field to which the invention belongs]
The present invention relates to a housing joint structure for an electronic device that houses various electronic devices.
[0002]
[Prior art]
Conventionally, a casing having a bottom plate and a side plate is known as this type of casing. In a casing having two side plates, two adjacent sides of the bottom plate are bent upward to form a side plate. There is what formed. When such a casing is exposed to a vibration atmosphere or an impact atmosphere and receives vibration or impact in the thickness direction of the side plate, the side plate vibrates around the bent portion, and the side plate deforms. In addition, there is a problem that a crack occurs in the bent portion and the durability is impaired.
[0003]
Therefore, in order to prevent this, a structure is generally used in which the edges of adjacent side plates are overlapped and the overlapped edges are joined together by screws or the like. However, in such a joining structure, there are problems that the number of parts required for assembly increases and the number of manufacturing steps increases in order to perform screwing.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a housing joint structure for an electronic device that is excellent in strength against vibration and impact and that can be easily assembled.
[0005]
[Means for Solving the Problems]
The invention according to claim 1, in housing junction structure of an electronic device joining the edges of adjacent one and the other side face plate, two adjacent sides of the bottom plate in which the electronic device is attached, the thickness of the bottom surface plate The one side plate and the other side plate are formed integrally with the bottom plate by bending at about 90 degrees in one direction, and a bent portion is formed between the one side plate and the other side plate and the bottom plate, the other side surface plate is formed longer than the side plates of the one, provided with an engaging portion on the edge portion of the side surface plate of the one, the clamping portion for clamping said engaging portion on the edge portion of the other side surface plate provided, the engaging portion is a protruding piece provided on the edge of the one side surface plate becomes bent formed on the side surface plate side of the other, the clamping portion abuts the outer surface of the projecting piece the the projecting outer surface while bending the inner surface of the edge portion of the other side surface plate, a part of the edge portion of the other side surface plate on the inner side Consists of a bending piece in contact with the inner surface of, which the projecting piece was pinched by the retaining state by said bent piece and the other side plate, since the clamping portion to sandwich the engaging portion from both sides, The other face plate provided with the clamping portion has a structure in which the other face plate is steady on one side and the other side in the thickness direction.
[0006]
Further , since the engaging portion is sandwiched between the bent piece and the edge portion of the other face plate, the sandwiched portion can be obtained only by processing the bent piece that contacts the other side surface of the protruding piece. Further, by sandwiching the protruding piece between the other side plate and the bent piece in a state of retaining, the vibration around the bent portion of the one side plate can be prevented.
