Description
本発明は、電子機器収納ケースの連結構造に関し、詳しくは、機能別にユニット化された複数のユニットで構成される電子機器収納ケースの一体化構造に関する。 The present invention relates to a connecting structure of electronic device storage cases, and more particularly to an integrated structure of an electronic device storage case composed of a plurality of units unitized by function.
電子機器の一種に、光ファイバをセンサとして用い、光ファイバ内で発生する後方散乱光を利用して光ファイバに沿った温度分布を測定するように構成された温度分布測定装置がある。 As one type of electronic equipment, there is a temperature distribution measuring device configured to measure a temperature distribution along an optical fiber using an optical fiber as a sensor and using backscattered light generated in the optical fiber.
このような温度分布測定装置の機能ブロックは、たとえば光ファイバに測定用のパルス光を入射するとともに光ファイバ内で発生する後方ラマン散乱光をストークス光とアンチストークス光に分離する光分波器を含む光学系ブロックと、光ファイバに沿った温度分布測定が行われるように各部を制御するとともに光分波器で分離されたストークス光とアンチストークス光がそれぞれ光電変換された電気信号に基づきストークス光とアンチストークス光の強度比を求めて温度を算出することにより光ファイバに沿った温度分布を演算表示する電気信号制御処理部と、基準用光ファイバ部に大別できる。 The functional block of such a temperature distribution measuring device includes, for example, an optical demultiplexer that makes pulse light for measurement enter an optical fiber and separates back Raman scattered light generated in the optical fiber into Stokes light and anti-Stokes light. Stokes light based on an electric signal including the optical system block and the Stokes light and the anti-Stokes light separated by the optical demultiplexer, respectively, which are controlled so that the temperature distribution measurement along the optical fiber is performed. And an anti-Stokes light intensity ratio, and calculating the temperature, it can be broadly divided into an electric signal control processing section for calculating and displaying a temperature distribution along the optical fiber, and a reference optical fiber section.
そして、これら複数の機能ブロックはたとえば図４に示すように共通する１つのケース１０に収納され、１台の温度分布測定装置として構成されていた。 The plurality of functional blocks are housed in a common case 10 as shown in FIG. 4, for example, and are configured as a single temperature distribution measuring device.
特許文献１には、光ファイバ分布型温度測定装置に関連する技術が記載されている。
特許文献２には、所定の機能を有する複数のユニットを連結して構成する技術が記載されている。
Patent Document 1 describes a technique related to an optical fiber distributed temperature measuring device.
Patent Document 2 describes a technique in which a plurality of units having a predetermined function are connected and configured.
しかし、複数の機能ブロックを共通する１つの収納ケースに収納する従来の構成によれば、当初の製品化段階で収納ケースの収納容積が決まっていることから、当初の製品化後の改良により開発された大規模な回路を組み込んだり、当初の製品よりも大きな端子台などを組み込むことはできないという問題がある。 However, according to the conventional configuration in which a plurality of functional blocks are stored in a common storage case, the storage capacity of the storage case is determined at the initial commercialization stage. There is a problem that it is impossible to incorporate a large-scale circuit that has been manufactured or a terminal block larger than the original product.
開発された回路が既存の収納ケースに収納できない場合には、その都度、回路の大きさを加味した金型を作成し、開発された回路を収納できるケースを作ることはできるが、回路が大きくなって収納できなくなるごとに新しく金型を作成するためにはかなり高額のコストがかかることになり、金型費用を回収するためには大量の生産台数が必要になる。 If the developed circuit cannot be stored in the existing storage case, you can create a mold that takes into account the size of the circuit and create a case that can store the developed circuit. Every time it can no longer be stored, it takes a very high cost to create a new mold, and a large number of units are required to recover the mold cost.
本発明は、これらの課題を解決するものであり、その目的は、収納対象となる複数の機能ブロックの数に合わせて、所定の収納容積を有する収納ケースを必要な数だけ連結一体化することにより、拡張性に優れた低コストの電子機器収納ケースの連結構造を実現することにある。 The present invention solves these problems, and an object thereof is to connect and integrate as many storage cases having a predetermined storage capacity as necessary in accordance with the number of functional blocks to be stored. Thus, a low-cost electronic device storage case connection structure excellent in expandability is realized.

以下、本発明の実施の形態について、図面を用いて詳細に説明する。図１は本発明の一実施例を示す構成説明図である。図１において、３個の収納ケース２０ａ〜２０ｃは、所定の収納容積を有する直方体状の同一形状に形成されたものであり、上下面にはそれぞれ複数の通気部２１、２２が設けられている。これら収納ケース２０ａ〜２０ｃは隣接する側面が密着するように配列され、これら収納ケースの上下面それぞれは上部連結部材３０および下部連結部材４０を介してネジ止め固定されている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing the construction of an embodiment of the present invention. In FIG. 1, three storage cases 20a to 20c are formed in the same shape of a rectangular parallelepiped having a predetermined storage volume, and a plurality of ventilation portions 21 and 22 are provided on the upper and lower surfaces, respectively. . The storage cases 20 a to 20 c are arranged so that adjacent side surfaces are in close contact with each other, and the upper and lower surfaces of the storage cases are fixed with screws via the upper connecting member 30 and the lower connecting member 40.
たとえば収納ケース２０ａにおいて、上下面の一部には、通気部２１、２２としてそれぞれ奥行方向に沿って奥行方向と直交するように複数のスリットが等間隔に設けられている。前面および背面の上面近傍には内部に連通する複数のネジ穴２３が設けられ、前面および背面の下面近傍には内部に連通する複数のネジ穴２４が設けられている。 For example, in the storage case 20a, a plurality of slits are provided at equal intervals on a part of the upper and lower surfaces as the ventilation portions 21 and 22 so as to be orthogonal to the depth direction along the depth direction. A plurality of screw holes 23 communicating with the inside are provided in the vicinity of the upper surface of the front surface and the back surface, and a plurality of screw holes 24 communicating with the inside are provided in the vicinity of the lower surface of the front surface and the back surface.
上部連結部材３０は板金加工されたものであって、長手方向に沿って長手方向と直交する方向に複数の連結辺３１が設けられるとともに、長手方向に沿った両側辺の収納ケース２０の上面近傍に設けられているネジ穴２３に対応する位置には、収納ケース２０の上面内に挿入できるようにＬ字形に折り曲げられた複数の取付片３２が離散的に形成されている。そして、これら取付片３２には、収納ケース２０の前面および背面の上面近傍に設けられたネジ穴２３と重なり合うように、取付穴３３が設けられている。 The upper connecting member 30 is formed by sheet metal processing, and is provided with a plurality of connecting sides 31 in a direction perpendicular to the longitudinal direction along the longitudinal direction, and in the vicinity of the upper surface of the storage case 20 on both sides along the longitudinal direction. A plurality of attachment pieces 32 bent in an L shape so as to be inserted into the upper surface of the storage case 20 are discretely formed at positions corresponding to the screw holes 23 provided in the storage case 20. The attachment pieces 32 are provided with attachment holes 33 so as to overlap with the screw holes 23 provided in the vicinity of the upper surfaces of the front surface and the rear surface of the storage case 20.
下部連結部材４０も板金加工されたものであって、長手方向に沿って長手方向と直交する方向に複数の連結辺４１が設けられるとともに、長手方向に沿った両側辺の収納ケース２０の下面近傍に設けられているネジ穴２４に対応する位置には、収納ケース２０の下面内に挿入できるようにＬ字形に折り曲げられた複数の取付片４２が離散的に形成されている。そして、これら取付片４２には、収納ケース２０の前面および背面の下面近傍に設けられたネジ穴２４と重なり合うように、取付穴４３が設けられている。 The lower connecting member 40 is also processed by sheet metal processing, and is provided with a plurality of connecting sides 41 in a direction perpendicular to the longitudinal direction along the longitudinal direction, and in the vicinity of the lower surface of the storage case 20 on both sides along the longitudinal direction. A plurality of attachment pieces 42 bent in an L shape so as to be inserted into the lower surface of the storage case 20 are discretely formed at positions corresponding to the screw holes 24 provided in the storage case 20. The attachment pieces 42 are provided with attachment holes 43 so as to overlap the screw holes 24 provided in the vicinity of the lower surface of the front surface and the rear surface of the storage case 20.
これら３個の収納ケース２０ａ〜２０ｃは、以下のようにして上部連結部材３０および下部連結部材４０を介して連結一体化される。すなわち、はじめに、３個の収納ケース２０ａ〜２０ｃを隣接する側面が密着するように配列する。 These three storage cases 20a to 20c are connected and integrated through the upper connecting member 30 and the lower connecting member 40 as follows. That is, first, the three storage cases 20a to 20c are arranged so that the adjacent side surfaces are in close contact with each other.
次に、これら密着配列された３個の収納ケース２０ａ〜２０ｃの上面内部に上部連結部材３０の取付片３２を差し込み、取付片３２に設けられている取付穴３３を、収納ケース２０の前面および背面の上面近傍に設けられたネジ穴２３と重ね合わせる。そして、これら重ね合わせた上部連結部材３０の取付穴３３とネジ穴２３にたとえばネジ穴２３側から固定ネジ５０を螺入し、上部連結部材３０を収納ケース２０ａ〜２０ｃの上面にネジ止め固定する。 Next, the attachment pieces 32 of the upper connecting member 30 are inserted into the upper surfaces of the three storage cases 20a to 20c arranged in close contact, and the attachment holes 33 provided in the attachment pieces 32 are connected to the front surface of the storage case 20 and It overlaps with the screw hole 23 provided in the vicinity of the upper surface of the back surface. Then, a fixing screw 50 is screwed into the mounting hole 33 and the screw hole 23 of the overlapped upper connecting member 30 from the screw hole 23 side, for example, and the upper connecting member 30 is fixed to the upper surfaces of the storage cases 20a to 20c with screws. .
同様に、これら密着配列された３個の収納ケース２０ａ〜２０ｃの下面内部に下部連結部材４０の取付片４２を差し込み、取付片４２に設けられている取付穴４３を、収納ケース２０の前面および背面の下面近傍に設けられたネジ穴２４と重ね合わせる。そして、これら重ね合わせた下部連結部材４０の取付穴４３とネジ穴２４にたとえばネジ穴２４側から固定ネジ５０を螺入し、下部連結部材４０を収納ケース２０ａ〜２０ｃの下面にネジ止め固定する。 Similarly, the attachment pieces 42 of the lower connecting member 40 are inserted into the lower surfaces of the three storage cases 20a to 20c arranged in close contact, and the attachment holes 43 provided in the attachment pieces 42 are connected to the front surface of the storage case 20 and It overlaps with the screw hole 24 provided near the lower surface of the back surface. Then, the fixing screw 50 is screwed into the mounting hole 43 and the screw hole 24 of the overlapped lower connecting member 40 from the screw hole 24 side, for example, and the lower connecting member 40 is fixed to the lower surfaces of the storage cases 20a to 20c with screws. .
図２は図１の電子機器収納ケースの連結構造をバックボードに取り付けた構成説明図であり、図２は図３の部分拡大図である。図２および図３において、密着配列された３個の収納ケース２０ａ〜２０ｃは、上部連結部材３０および下部連結部材４０を挟み込むようにして製品固定用のネジ５０でバックボード６０に固定される。 FIG. 2 is an explanatory diagram of a configuration in which the connection structure of the electronic device storage case of FIG. 1 is attached to the backboard, and FIG. 2 is a partially enlarged view of FIG. 2 and 3, the three storage cases 20a to 20c arranged in close contact with each other are fixed to the backboard 60 with a product fixing screw 50 so as to sandwich the upper connecting member 30 and the lower connecting member 40 therebetween.
なお、収納ケース２０ａ〜２０ｃの前面には、たとえば所定の形状に板金加工されたフロントカバー７０が取り付けられる。 For example, a front cover 70 that is processed into a predetermined shape by sheet metal processing is attached to the front surfaces of the storage cases 20a to 20c.
バックボード６０には、たとえば電源ブロックが収納される収納ケース８０も固定されている。 A storage case 80 for storing, for example, a power supply block is also fixed to the backboard 60.
これらの構成により、３個の収納ケース２０ａ〜２０ｃの上面は上部連結部材３０で前面部と背面部をまたぐようにして連結固定され、下面は下部連結部材４０で前面部と背面部をまたぐようにして連結固定されるので、振動などによる収納ケース２０ａ〜２０ｃのねじれを抑制することができ、連結一体化された収納ケース２０ａ〜２０ｃの強度が増すことになる。 With these configurations, the upper surfaces of the three storage cases 20a to 20c are connected and fixed by the upper connecting member 30 so as to straddle the front surface portion and the back surface portion, and the lower surface is straddled between the front surface portion and the back surface portion by the lower connecting member 40. As a result, the torsion of the storage cases 20a to 20c due to vibration or the like can be suppressed, and the strength of the connected and integrated storage cases 20a to 20c is increased.
そして、密着配列された３個の収納ケース２０ａ〜２０ｃに対して上部連結部材３０および下部連結部材４０を隙間を生じないガタを持たないで差し込むことにより、強度の向上だけでなく配列された収納ケース２０ａ〜２０ｃ間の位置決め精度も向上し、バックボード６０に対してより正確な位置に取り付けることができる。 Then, by inserting the upper connecting member 30 and the lower connecting member 40 into the three storage cases 20a to 20c that are closely arranged without having a backlash that does not generate a gap, the storage is arranged as well as improving the strength. Positioning accuracy between the cases 20a to 20c is also improved, and the case 20a to 20c can be attached to the backboard 60 at a more accurate position.
なお、上部連結部材３０および下部連結部材４０は、長手方向に沿って長手方向と直交する方向に複数の連結辺３１および４１が設けられていることから、上部連結部材３０および下部連結部材４０を介して連結一体化した状態であっても収納ケース２０ａ〜２０ｃの放熱特性が損なわれることはない。 Since the upper connecting member 30 and the lower connecting member 40 are provided with a plurality of connecting sides 31 and 41 in the direction perpendicular to the longitudinal direction along the longitudinal direction, the upper connecting member 30 and the lower connecting member 40 are connected to each other. Even if it is connected and integrated, the heat dissipation characteristics of the storage cases 20a to 20c are not impaired.
さらに、上部連結部材３０および下部連結部材４０は、板金加工により形成されているので、電磁ノイズに対するシールド特性の向上が図れる。特に、フロントカバーが板金の場合にはフロントカバーと連結部品、バックボードと連結部品の固定ネジを増やすことにより多点結合となり、全体的に金属で覆われた構造を実現できノイズ特性が向上する。 Furthermore, since the upper connecting member 30 and the lower connecting member 40 are formed by sheet metal processing, it is possible to improve the shielding characteristics against electromagnetic noise. In particular, when the front cover is a sheet metal, by increasing the number of fixing screws between the front cover and the connecting parts and between the backboard and the connecting parts, a multi-point connection is realized, and a structure covered with metal as a whole can be realized and noise characteristics are improved. .
図２のように構成される電子機器収納ケースの連結構造には、分割可能な複数の機能ブロックで構成される電子機器、たとえば電気信号制御処理ブロックと光学系ブロックと基準光ファイバブロックとで構成される光ファイバ分布型温度測定装置を収納できる。 The electronic device storage case connection structure configured as shown in FIG. 2 includes an electronic device including a plurality of functional blocks that can be divided, for example, an electric signal control processing block, an optical system block, and a reference optical fiber block. An optical fiber distributed temperature measuring device can be accommodated.
光ファイバ分布型温度測定装置の収納にあたっては、第１の収納ケース２０ａには電気信号制御処理ブロックが収納され、第２の収納ケース２０ｂには光学系ブロックが収納され、第３の収納ケース２０ｃには基準光ファイバが収納される。そして、収納ケース８０には、光ファイバ分布型温度測定装置の各機能ブロックを駆動するための電源を供給する電源ブロックが収納される。 In storing the optical fiber distributed temperature measuring device, the first storage case 20a stores the electrical signal control processing block, the second storage case 20b stores the optical system block, and the third storage case 20c. Contains a reference optical fiber. The storage case 80 stores a power supply block that supplies power for driving each functional block of the optical fiber distributed temperature measuring device.
なお、電子機器収納ケースの連結構造に収納される電子機器は、光ファイバ分布型温度測定装置に限るものではなく、分割可能な複数の機能ブロックで構成されるその他の電子機器であってもよい。 The electronic device stored in the connection structure of the electronic device storage case is not limited to the optical fiber distributed temperature measuring device, and may be another electronic device configured by a plurality of functional blocks that can be divided. .
このような構成によれば、収納対象となる機能ブロックの数に合わせて所定の収納容積を有する収納ケースを必要な数だけ連結一体化すればよく、収納容積の大きさとして製品化後の改良により開発される可能性がある機能ブロックの最大の大きさを考慮しておくことにより拡張性に優れた低コストの電子機器収納ケースの連結構造が得られ、従来のように開発された回路が既存の収納ケースに収納できなくなってしまうことを回避できる。 According to such a configuration, a necessary number of storage cases having a predetermined storage capacity may be connected and integrated in accordance with the number of functional blocks to be stored, and the improvement of the storage capacity after the commercialization is achieved. By taking into account the maximum size of functional blocks that can be developed by a low-cost electronic device storage case connection structure with excellent expandability, a circuit developed as in the past can be obtained. It is possible to avoid being unable to be stored in the existing storage case.
また、所定の収納容積を有する収納ケースを標準化しておくことにより、各種電子機器の機能ブロックの収納ケースとして用いることができ、大量生産による収納ケースの低コスト化が図れる。 Further, by standardizing a storage case having a predetermined storage volume, it can be used as a storage case for functional blocks of various electronic devices, and the storage case can be reduced in cost by mass production.
以上説明したように、本発明によれば、拡張性に優れた低コストの電子機器収納ケースの連結構造を実現できる。 As described above, according to the present invention, it is possible to realize a low-cost electronic device storage case connection structure excellent in expandability.
