Description

本願は、電子機器筐体に関するものである。 The present application relates to an electronic device housing.

自動車工業製品において、車両の制御機器等の電子機器は、雨により被水する可能性のある位置または水没が懸念される位置に搭載される場合、筐体間で強固なシール機構を設けて被水から保護する必要がある。しかしながら、電子機器の内部のメンテナンスおよびリサイクルを行う際はケースを分解する必要があり、その分解作業に多くの工数をとられる。特に、液状ガスケットを用いて接合する場合、その接着力により分解し難いという問題がある。 In automotive industrial products, when electronic equipment such as vehicle control equipment is mounted in a location where it may be exposed to water due to rain or where there is a risk of submersion, a strong sealing mechanism must be provided between the casings. Must be protected from water. However, when performing internal maintenance and recycling of electronic devices, it is necessary to disassemble the case, and the disassembly work requires many man-hours. In particular, when joining using a liquid gasket, there is a problem in that it is difficult to disassemble due to its adhesive strength.

従来用いられる分解構造としては、特許文献１に示された方法がある。特許文献１に記載された電子機器筐体は、上下のケースのフランジ部分を液状ガスケットでシールした構造を持ち、ケースのフランジ間を固定するネジ以外に、一方に貫通したメネジを設け、他方に貫通穴を設けない部分を有している。分解時には、このメネジの部分にオネジを締め上げることにより貫通したメネジから突き出たオネジが他方のフランジに接触し、押し広げる力で対象ケースを分解することができる。 As a conventionally used decomposition structure, there is a method shown in Patent Document 1. The electronic device housing described in Patent Document 1 has a structure in which the flanges of the upper and lower cases are sealed with a liquid gasket, and in addition to the screws that fix the flanges of the case, there is a female screw that penetrates one side and a female screw that penetrates the other side. It has a portion without a through hole. During disassembly, by tightening the male screw onto this female thread, the male screw protruding from the female screw that penetrates comes into contact with the other flange, and the target case can be disassembled by the force of pushing it apart.

従来の分解構造の場合、分解時のみオネジが挿入されるため通常時はネジ穴がむき出しになっており、雨水等の被水によってネジ穴が錆びることがある。その場合、オネジが挿入し難くなって分解に手間がかかる。また、オネジが挿入できる場合でも、被締結物であるケースにメネジを設けることが前提となり、ケースの材料選定に制約を受ける。 In the case of conventional disassembly structures, the male screws are inserted only during disassembly, so the screw holes are exposed under normal conditions, and the screw holes may rust due to exposure to water such as rainwater. In that case, it becomes difficult to insert the male screw and it takes time to disassemble it. Further, even if a male screw can be inserted, it is assumed that a female screw is provided in the case to be fastened, and there are restrictions on the material selection of the case.

本願は、この様な問題点を解決するためになされたものであって、被水してもネジ穴が錆びることがなく、ケースを分解する時に容易にケース間を分離できる構造を持った電子機器筐体を得ること目的とする。 The present application was made to solve these problems, and the purpose of this application is to provide an electronic device with a structure that prevents the screw holes from rusting even when exposed to water, and that allows the cases to be easily separated when the cases are disassembled. The purpose is to obtain a device casing.

本願に係わる電子機器筐体は、第一のフランジを有する第一のケースと、前記第一のフランジとシール材を介して接着された第二のフランジを有する第二のケースと、を備え、前記第一のフランジと前記第二のフランジとの接合部の少なくとも一部に、前記第一のケースと前記第二のケースとを分解する分解用ネジ部が形成され、前記分解用ネジ部は、前記第一のフランジの底を有するネジ穴に設けられたメネジと、このメネジに締結されたオネジと、前記第二のフランジに設けられ前記オネジの頭を覆う蓋部とで構成され、前記蓋部には、前記オネジの軸方向にこのオネジの頭よりも小さい径の貫通穴が設けられたものである。 The electronic device housing according to the present application includes a first case having a first flange, and a second case having a second flange bonded to the first flange via a sealing material, A disassembly screw portion for disassembling the first case and the second case is formed in at least a part of the joint between the first flange and the second flange, and the disassembly screw portion is , consisting of a female screw provided in a screw hole having a bottom of the first flange, a male screw fastened to the female screw, and a lid portion provided on the second flange and covering the head of the male screw; The lid portion is provided with a through hole having a diameter smaller than the head of the male screw in the axial direction of the male screw .

本願によれば、前記第一のフランジと前記第二のフランジとの接合部の少なくとも一部に、前記第一のケースと前記第二のケースとを分解するネジ部が設けられており、このネジ部にオネジをメネジが締結された状態で設けられている。そのため、オネジがメネジのネジ穴を塞ぐように形成されているのでネジ穴が露出することなく、被水に対してネジ穴が錆びることがない。また、分解時に別途オネジを用意することはなく、締結されたオネジとメネジを使用して第一のケースと第二のケースの分解が可能である。 According to the present application, at least a part of the joint between the first flange and the second flange is provided with a threaded part for disassembling the first case and the second case, and A male thread and a female thread are connected to the threaded part. Therefore, since the male screw is formed to close the screw hole of the female screw, the screw hole is not exposed and does not rust due to exposure to water. Further, the first case and the second case can be disassembled using the fastened male and female screws without having to prepare a separate male screw during disassembly.

実施の形態１．
図１は、本願の実施の形態１による電子機器筐体の全体を各構成要素に分解した状態を示す斜視図である。図１において、電子機器筐体２０は、メネジ３が設けられた第一のフランジ２を有する第一のケース１と、貫通穴６ａとオネジ７ｂのネジの頭を覆う蓋部９に形成された貫通穴６ｂが設けられた第二のフランジ５を有する第二のケース４とで構成されている。また、第一のケース１の第一のフランジ２と第二のケース４の第二のフランジ５とはその接合部にシール材となる液状ガスケット８を挟んで構成されており、オネジ７ａの締付け力によって、シール材は第一のフランジ２と第二のフランジ５の接合部の全体に広がり、ケースの内部が封止されるシール構造となっている。また、分解時の分解のためのオネジ７ｂが設けられている。 Embodiment 1.
FIG. 1 is a perspective view showing a state in which the entire electronic device casing according to Embodiment 1 of the present application is disassembled into each component. In FIG. 1, an electronic device housing 20 includes a first case 1 having a first flange 2 provided with a female screw 3, and a lid portion 9 that covers the through hole 6a and the head of the male screw 7b. The second case 4 has a second flange 5 provided with a through hole 6b. In addition, the first flange 2 of the first case 1 and the second flange 5 of the second case 4 are configured with a liquid gasket 8 serving as a sealing material sandwiched between their joints, and the tightening of the male screw 7a Due to the force, the sealing material spreads over the entire joint between the first flange 2 and the second flange 5, creating a sealing structure in which the inside of the case is sealed. Further, a male screw 7b is provided for disassembly during disassembly.

図１では、電子機器筐体２０に格納される部品である電子機器、基板、ケーブルおよびコネクタ等についての図示を省略する。また、電子機器筐体２０の外部との接続についての図示も省略する。また、後述する図２から図５においても同様の扱いとする。なお、各図の中の符号は対応する部位は同一符号で表すものとする。
図２は、電子機器筐体２０の外観を示す斜視図である。また、図３は、図２のＡＡ断面となるネジ部の断面を示す模式図である。第一のフランジ２と第二のフランジ５の接合部には、筐体の締結用のネジ部１０ａと分解用のネジ部１０ｂとが設けられている。分解用のネジ部１０ｂは、少なくとも第一のフランジ２と第二のフランジ５の接合部の少なくとも一部に設けられる。オネジ７ｂの頭の上に、蓋部９があり、オネジ７ｂの頭よりも径の小さい貫通穴６ｂが設けられている。 In FIG. 1, illustrations of electronic devices, circuit boards, cables, connectors, and the like, which are components stored in the electronic device housing 20, are omitted. Further, illustrations of connections to the outside of the electronic device housing 20 are also omitted. Further, the same applies to FIGS. 2 to 5, which will be described later. Note that the same reference numerals are used to indicate corresponding parts in each figure.
FIG. 2 is a perspective view showing the external appearance of the electronic device housing 20. As shown in FIG. Further, FIG. 3 is a schematic diagram showing a cross section of the threaded portion taken along the line AA in FIG. 2. As shown in FIG. A threaded portion 10a for fastening the housing and a threaded portion 10b for disassembly are provided at the joint between the first flange 2 and the second flange 5. The threaded portion 10b for disassembly is provided at least in a portion of the joint between the first flange 2 and the second flange 5. A lid portion 9 is provided on the head of the male screw 7b, and a through hole 6b having a smaller diameter than the head of the male screw 7b is provided.

通常は、図３に示すように締結用のネジ部１０ａでは、オネジ７ａがメネジ３に締結された状態であり、分解用のネジ部１０ｂでも、オネジ７ｂがメネジ３に締結された状態となっている。電子機器筐体２０を分解するときは、まず、筐体のすべての締結用のネジ部１０ａのオネジ７ａをドライバ等の工具を使用してメネジ３から取り外す。つぎに、分解用のネジ部１０ｂに対し貫通穴６ｂを通して工具を使用し、オネジ７ｂの頭を緩める方向にネジを回す。オネジ７ｂの頭に設けられたフランジ部が蓋部９と接触し、蓋部９を押し上げる。この力が第一のケース１と第二のケース４とを分解する分解力として働き、第一のフランジ２と第二のフランジ５の間にある液状ガスケット８の接着力に打ち勝って電子機器筐体２０を分解することができる。
このように、ドライバ等の工具を使用して、簡単に電子機器筐体２０を分解することが可能である。 Normally, as shown in FIG. 3, in the threaded part 10a for fastening, the male thread 7a is fastened to the female thread 3, and in the threaded part 10b for disassembly, the male thread 7b is fastened to the female thread 3. ing. When disassembling the electronic device housing 20, first, the male screws 7a of all the fastening screw portions 10a of the housing are removed from the female screws 3 using a tool such as a screwdriver. Next, using a tool, insert the through hole 6b into the threaded part 10b for disassembly, and turn the screw in a direction to loosen the head of the male screw 7b. The flange portion provided on the head of the male screw 7b comes into contact with the lid portion 9 and pushes the lid portion 9 up. This force acts as a disassembly force to disassemble the first case 1 and the second case 4, and overcomes the adhesive force of the liquid gasket 8 between the first flange 2 and the second flange 5, thereby disassembling the electronic device case. The body 20 can be disassembled.
In this way, it is possible to easily disassemble the electronic device housing 20 using a tool such as a screwdriver.

以上のように、分解用のネジ部１０ｂは通常はオネジ７ｂがメネジ３に締結された状態であるため、メネジ３のネジ穴がむき出しの状態にならず、雨水等の被水による錆びに強い構造となっている。
また、オネジ７ａ、７ｂに防錆用のコーティングを施すことによって、被水による錆びの進行を抑えることができ、分解時の作業が容易になる。
また、図３に示すように、オネジ７ｂの頭に貫通穴６ｂよりも径の大きなフランジ部を有するネジを用いることにより、ネジの頭と工具とが篏合するために必要な貫通穴６ｂの径を確保することが容易となる。 As described above, the threaded part 10b for disassembly is usually in a state where the male thread 7b is fastened to the female thread 3, so the screw hole of the female thread 3 is not exposed, and it is resistant to rust due to rainwater etc. It has a structure.
Moreover, by applying a rust-preventing coating to the male screws 7a and 7b, it is possible to suppress the progress of rust due to exposure to water, and the work at the time of disassembly becomes easier.
In addition, as shown in FIG. 3, by using a screw having a flange portion with a larger diameter than the through hole 6b on the head of the male screw 7b, the through hole 6b necessary for the screw head and the tool to fit together can be formed. It becomes easy to secure the diameter.

また、図３に示すように、分解用のオネジ７ｂの頭に設けたフランジ部には摩擦低減材１１が塗布されており、オネジ７ｂのフランジ部と接触する蓋部９には接触する範囲に表面処理加工面１２が設けられている。このようにすることで、分解時にオネジ７ｂのフランジ部と蓋部９が接触するが、摩擦低減材により接触による傷付きが緩和される。また、分解時にオネジ７ｂのフランジ部と蓋部９が接触するが、蓋部９の接触面に摩擦を軽減する表面処理加工面１２を設けることにより接触による傷付きをより緩和できる。

Further, as shown in FIG. 3, a friction reducing material 11 is applied to the flange portion provided on the head of the male screw 7b for disassembly, and a friction reducing material 11 is applied to the contact area of the lid portion 9 that contacts the flange portion of the male screw 7b. A surface treatment surface 12 is provided. By doing so, the flange portion of the male thread 7b and the lid portion 9 come into contact during disassembly, but the friction reducing material reduces damage caused by the contact. Further, the flange portion of the male screw 7b and the lid portion 9 come into contact during disassembly, but by providing the surface treatment surface 12 that reduces friction on the contact surface of the lid portion 9, damage caused by contact can be further alleviated.

また、締結用のネジ部１０ａのメネジ３も、分解用のネジ部１０ｂのメネジ３も第一のフランジの側に設けられており、第二のフランジ５の側にメネジを切ることはなく、第二のケース４の材料選定にネジを切ることによる制約を受けることがない。例えば、アルミダイカスト、鉄または銅からなる板金、または、樹脂成型品を用いることが可能である。これにより軽量化および低コスト化を図ることが可能になる。 Further, both the female thread 3 of the threaded part 10a for fastening and the female thread 3 of the threaded part 10b for disassembly are provided on the first flange side, and there is no need to cut a female thread on the second flange 5 side. The material selection for the second case 4 is not restricted by cutting the thread. For example, it is possible to use aluminum die casting, a sheet metal made of iron or copper, or a resin molded product. This makes it possible to reduce weight and cost.

図４は、分解用のオネジ７ｂの頭にフランジ部を設けたことにより、ゴム等でできた吸着ビット１３を工具として使用し、搬送、吸着、ネジ締め、ネジ緩めをすることが可能となる例を示したものである。このような吸着ビット１３を用いることによって、電子機器筐体２０の組立および分解の作業の自動化、標準化が可能となる。
また、オネジ７ａとオネジ７ｂの頭にフランジ部を設けたことによりオネジに雨水等が溜まらない形状となっており、錆びにくい構造になっている。そのため、組立、分解時に、ネジの頭のフランジの平面でネジへの吸着ビット１３の吸着が可能になり、吸着ビット１３の径を小さく設定することが可能である。 FIG. 4 shows that by providing a flange part on the head of a male screw 7b for disassembly, a suction bit 13 made of rubber or the like can be used as a tool to transport, suction, screw tightening, and screw loosening. This is an example. By using such a suction bit 13, it becomes possible to automate and standardize the assembly and disassembly work of the electronic device housing 20.
Further, by providing flanges on the heads of the male screws 7a and 7b, the male screws have a shape that does not allow rainwater to accumulate, resulting in a structure that is resistant to rust. Therefore, during assembly and disassembly, the suction bit 13 can be suctioned to the screw by the plane of the flange of the screw head, and the diameter of the suction bit 13 can be set small.

図５は、電子機器筐体２０の分解用のネジ部１０ｂの構造を拡大した斜視図で示したものである。図５においてオネジ７ｂが締結されている第一のフランジ２の座面と第二のフランジ５に設けられた蓋部９との間に、開口部１４が第二のケース４の外に向けて設けられている。また、蓋部９には補強部となるリブ１５が設けられている。
このように開口部１４を設けることにより、オネジ７ｂと第二のフランジ５の間に雨水等が浸入した場合でも、開口部１４によって雨水等が排出され溜まることがない。
また、補強部となるリブ１５を設けることにより、分解時の第二のケース４、第二のフランジ５の変形、破損を防止することが可能になる。ただしリブの形、位置は図に限定されるものではなく、分解時のオネジ７ｂと蓋部９との接触による分解力に耐えられる構造であれば別の形状、位置でもよい。 FIG. 5 is an enlarged perspective view showing the structure of the screw portion 10b for disassembling the electronic device housing 20. As shown in FIG. In FIG. 5, an opening 14 is formed between the seat surface of the first flange 2 to which the male screw 7b is fastened and the lid 9 provided on the second flange 5, and is opened toward the outside of the second case 4. It is provided. Further, the lid portion 9 is provided with ribs 15 that serve as reinforcing portions.
By providing the opening 14 in this manner, even if rainwater or the like enters between the male screw 7b and the second flange 5, the rainwater or the like is discharged through the opening 14 and does not accumulate.
Further, by providing the rib 15 serving as a reinforcing portion, it becomes possible to prevent deformation and damage of the second case 4 and second flange 5 during disassembly. However, the shape and position of the ribs are not limited to those shown in the figure, and other shapes and positions may be used as long as the structure can withstand the disassembly force caused by the contact between the male screw 7b and the lid part 9 during disassembly.

なお、本願の実施の形態１では、第一のケース１を下に、第二のケース４を上にした状態で説明したが、上下左右等の向きについて制約はない。
また、分解用のネジ部１０ｂは１つとして説明したが、ケースの周囲の複数箇所に設けてもよい。締結用のネジ部１０ａについても７個として図示したが、個数に制約はない。
電子機器筐体は、第一のケースと第二のケースの２つとしたが、より複雑な形状を持ったものでも可能である。また、２つ以上の複数のケースに分割されている場合でも同様な構成が可能であり、同様な効果を奏することが可能である。 In addition, in Embodiment 1 of the present application, the first case 1 is described as being on the bottom and the second case 4 is on the top, but there are no restrictions on the orientation such as up, down, left, and right.
Further, although the explanation has been made assuming that there is one threaded portion 10b for disassembly, it may be provided at multiple locations around the case. Although seven screw portions 10a for fastening are shown in the figure, there is no restriction on the number.
Although there are two electronic device casings, the first case and the second case, it is also possible to use one with a more complicated shape. Furthermore, even when the system is divided into two or more cases, a similar configuration is possible and similar effects can be achieved.

本願は、例示的な実施の形態が記載されているが、実施の形態に記載された様々な特徴、態様、及び機能は特定の実施の形態の適用に限られるのではなく、単独で、または様々な組み合わせで実施の形態に適用可能である。
