Description

【０００１】
【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.

Further, the outer surface 7G of the protruding piece 7 is in contact with the inner surface 4N of the other side plate 4. A pair of notch grooves 8 and 8 in the length direction are formed in the edge portion 4F of the other side face plate 4, and the edge 4F portion sandwiched between the notch grooves 8 and 8 is bent so as to be cut and raised to the inner surface side. The bent piece 9 is formed, and the distal end side of the bent piece 9 is formed in parallel with the other side plate 4. The outer surface 9G on the distal end side of the bent piece 9 abuts on the inner surface 7N of the protruding piece 7, and the protruding piece 7 is sandwiched between the other side plate 4 and the bent piece 9. The other side surface portion 4 and the bent piece 9 constitute a clamping portion 10, and the clamping portion 10 is formed above the side surface portion 4. Further, it is preferable that the protruding piece 7 is sandwiched between the other side plate 4 and the bent piece 9 in a retaining state. In the figure, reference numeral 11 denotes a notch formed in the edge portion 4F of the other side face plate 4, and engages with a fixing screw (not shown).
[0009]
As described above, in this embodiment, corresponding to claim 1, in the housing joining structure of the electronic device for joining the edge portions 3F, 4F of the one side plate 3 and the other side plate 3, 4 adjacent to each other, The matching two sides are bent at approximately 90 degrees on one side in the thickness direction of the bottom plate 2 so that one and the other side plates 3 and 4 are formed integrally with the bottom plate 2, and the one and the other side plates 3, Bent portions 5 and 6 are formed between 4 and the bottom plate 2, the other side plate 4 is formed longer than one side plate 3, and a protrusion serving as an engaging portion at the edge 3 </ b> F of the one side plate 3. While providing the piece 7, the clamping part 10 which clamps the protruding piece 7 is provided in the edge part 4F of the other side plate 4, and the engaging part is provided with the protruding piece 7 provided in the edge part 3F of the one side plate 3 on the other side. bent formed become by the side plate 4 side, sandwiching portion 10 includes an inner surface 4N of the other side plate 4 in contact with the outer surface 7G of the projecting piece 7, on the other face 4 of the edge 4F Ri outer surface co when bent to the inner side part 4G is Do from the bent piece 9 abuts against the inner surface 7N projected piece 7, the projecting piece 7 in a state retained by the other side plate 4 and the bent piece 9 Since the sandwiching portion 10 sandwiches the projecting piece 4 from both sides, the other side plate 4 provided with the sandwiching portion 10 is structured to be steady on one side and the other side in the thickness direction. Thus, even when subjected to vibration or impact, the other side plate 4 does not vibrate around the bent portion 5, and an excellent structure against vibration or impact is obtained.
[0010]
Also, just to process the bending piece 9 abuts against the inner surface or the outer surface side of the collision piece 7, it is possible to obtain a clamping portion 10, it is possible to perform the processing easily.
[0011]
Furthermore, by pinched the previous SL projection piece 7 at the retaining state by the other side plate 4 and the bent piece 9, it is possible to prevent vibration around the bending portion 5 of one of the side plates 3 . Further, since the bent piece 9 is formed on the inner surface side, it is not necessary to form a protruding portion on the outer surface 4G of the other side surface portion 4. Further, since the bent piece 9 is obtained by cutting and raising a part of the edge 4F, the processing is easy.
[0012]
The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the present invention .
[0013]
