Description

この発明は、例えばハードディスクドライブケースの筺体と蓋体のシール部位のような一方の部材と他方の部材間におけるシール部位に、断面方形状の定型ガスケットを用いてシールするシール構造に関する。   The present invention relates to a sealing structure that seals a sealing portion between one member and the other member, such as a sealing portion of a housing and a lid of a hard disk drive case, using a fixed gasket having a rectangular cross section.

従来、ハードディスクドライブ等のＯＡ機器、携帯電話等の通信機器、クリーンルーム、食品工場および病院、等のシール部位においては、一方の部材と他方の部材間がガスケットでシール（密閉）されている。このシールは、外側からの塵埃や水分等の異物の侵入を防止したり、及び遮音のために行われる。
ガスケットは、例えば、ウレタンアクリレート系およびポリオレフィン系エラストマーを材料とし、その成形は、射出成形によってカバー（蓋体）と一体成形させる方法（例えば、特許文献１参照）、液状の材料をディスペンサーを操作しながら紐状に塗出する方法（例えば、特許文献２参照）および予め所定形状に形成されたガスケットをカバー（蓋体）へ貼り付ける方法（例えば、特許文献３参照）等がある。予め所定形状に形成されたガスケットをカバー（蓋体）へ貼り付ける方法の場合は、幅広のシートからプレス等によって所定形状に打ち抜きガスケットを形成した後、接着剤を塗布して貼り付ける方法や、樹脂フィルムへ所定形状を射出成形し、フィルムと反対側のガスケット面に接着剤を塗布し貼り付けた後、フィルムを剥がす方法がある。 Conventionally, in sealing parts such as OA equipment such as hard disk drives, communication equipment such as mobile phones, clean rooms, food factories and hospitals, one member and the other member are sealed (sealed) with a gasket. This sealing is performed to prevent intrusion of foreign matters such as dust and moisture from the outside, and for sound insulation.
The gasket is made of, for example, urethane acrylate type and polyolefin type elastomer, and is molded by a method of integrally molding with a cover (lid body) by injection molding (for example, refer to Patent Document 1), and operating a liquid material by operating a dispenser. There are, for example, a method of painting in a string shape (for example, see Patent Document 2), a method of sticking a gasket formed in a predetermined shape in advance to a cover (lid body) (for example, see Patent Document 3), and the like. In the case of a method of pasting a gasket formed in a predetermined shape on a cover (lid body), after forming a gasket into a predetermined shape by a press or the like from a wide sheet, a method of applying and bonding an adhesive, There is a method in which a predetermined shape is injection-molded on a resin film, an adhesive is applied to a gasket surface opposite to the film, and the film is peeled off.

定型ガスケットとは、予め一定形状をしたガスケットのことで、施工後固まる液状のコーキング材や液状のガスケット材など液状のものに対し、予めある定型をなしたガスケットという意味で定型ガスケットという。
従来の定型ガスケットは、通常、図９に示すように弾性体（例えば、ポリウレタン系の発泡体あるいは非発泡体）で形成されるガスケット材の原板（幅広のシート状）６からプレスにより所定形状の定型ガスケット４に打ち抜くことによって製造される。このような定型ガスケット４は、シール部位に装着してシーリングする。一方の部材と他方の部材を、ハードディスクドライブケース（以下、ＨＤＤケースという）の筺体と蓋体の場合で説明すると、例えば、図１０および図１１に示すように、ＨＤＤケース１の筺体２と蓋体３との間において蓋体３のシール部位３ａに定型ガスケット４が接着（粘着）剤５で接着されている。この定型ガスケット４は、筺体２と蓋体３との間に挟まれて圧縮してシーリングする。即ち、定型ガスケット４は、筺体２と蓋体３との間に介在してある程度圧縮され、気密性、防水性、防湿性、防塵性およびクッション性を確保するものである。 The fixed gasket is a gasket having a fixed shape in advance, and is called a fixed gasket in the meaning of a predetermined gasket with respect to a liquid material such as a liquid caulking material or a liquid gasket material that hardens after construction.
As shown in FIG. 9, a conventional fixed gasket is usually pressed into a predetermined shape by pressing from an original sheet (wide sheet shape) 6 of a gasket material formed of an elastic body (for example, polyurethane foam or non-foam). It is manufactured by punching into a fixed gasket 4. Such a fixed gasket 4 is attached to a seal portion and sealed. One member and the other member will be described in the case of a housing and lid of a hard disk drive case (hereinafter referred to as HDD case). For example, as shown in FIGS. 10 and 11, the housing 2 and lid of the HDD case 1 Between the body 3, the fixed gasket 4 is bonded to the seal part 3 a of the lid 3 with an adhesive (adhesive) agent 5. The fixed gasket 4 is sandwiched between the casing 2 and the lid 3 and compressed and sealed. That is, the fixed gasket 4 is interposed between the casing 2 and the lid 3 and is compressed to some extent, thereby ensuring airtightness, waterproofness, moistureproofness, dustproofness, and cushioning properties.

そのために定型ガスケットは、密度及び圧縮応力等が重要視される。密度及び圧縮応力が低すぎると、柔軟に成りすぎてガスケットのシール性、気密性、防水性、防湿性、防塵性及びクッション性、等が低下し、逆に高すぎると変形し難くなりシール面への追従性に欠け、それによりやはりシール性、気密性、防水性、防湿性、防塵性及びクッション性が低下するからである。この圧縮応力の調整は、定型ガスケットの断面形状を変えたり（例えば、特許文献４参照）、ガスケット材の組成配合や添加物等の処方を変えたり、密度を変えることで行うことが可能である。

If the density and compressive stress are too low, it becomes too flexible and the sealing performance, airtightness, waterproofness, moisture resistance, dustproofness and cushioning, etc. of the gasket will decrease. This is because the following performance is lacking, and thus the sealing performance, airtightness, waterproofness, moisture resistance, dustproofness and cushioning properties are lowered. The compression stress can be adjusted by changing the cross-sectional shape of the standard gasket (for example, see Patent Document 4), changing the composition of the gasket material, the prescription of additives, etc., or changing the density. .

前記したような射出成形によってカバー（蓋体）と一体成形させる方法や、液状の材料をディスペンサーを操作しながら紐状に塗出する方法で、ガスケットを形成すると、ガスケットの形状は断面椀型や断面だるま型となる。
しかしながら、予め所定形状に形成された定型ガスケットは、幅広のシート状に形成されたガスケット材の原板からプレスにより所定形状の定型ガスケットに打ち抜き形成することが多く、そのためガスケットの形状は、断面方形状（正方形および長方形）となり、断面方形状の定型ガスケットでは、圧縮量が断面方向に一定となるために、シール性を満足できない場合がある。例えば、ガスケット圧縮量に影響するガスケット厚さ、蓋体（カバー）および筺体（ベース）寸法がばらついた時、圧縮量が小さいと外部との遮断（シール性）が不十分であったり、圧縮量が大きいと蓋体（カバー）組み付け時にガスケットの反力に蓋体が負け変形を起こしたりする場合がある。かといって、圧縮応力を調整するためにガスケットの断面形状を変化させるには、打ち抜き形成する定型ガスケットでは限度があり、断面形状を変化させようとすれば、打ち抜き形成後に、断面形状を変化させる加工が必要となり、製造に手数がかかり、コストも高くなる課題がある。 When a gasket is formed by a method of integrally molding with a cover (lid) by injection molding as described above, or by applying a liquid material in a string shape while operating a dispenser, the shape of the gasket is a cross-sectional saddle shape or It becomes a cross-shaped daruma.
However, fixed gaskets that have been formed in a predetermined shape in advance are often formed by punching from a gasket material base plate that has been formed into a wide sheet shape into a fixed gasket of a predetermined shape by pressing. In the case of a fixed gasket having a square cross section, the amount of compression is constant in the cross sectional direction, and thus the sealing performance may not be satisfied. For example, when the gasket thickness, the lid (cover), and the housing (base) dimensions that affect the compression amount of the gasket vary, if the compression amount is small, the external insulation (sealability) may be insufficient, or the compression amount If it is large, the lid body may lose its deformation due to the reaction force of the gasket when the lid body (cover) is assembled. However, in order to change the cross-sectional shape of the gasket in order to adjust the compressive stress, there is a limit to the standard gasket that is punched and formed, and if the cross-sectional shape is to be changed, the cross-sectional shape is changed after the punching is formed. There is a problem that processing is necessary, man-hours are required for manufacturing, and costs are increased.

この発明は、このような課題を解決せんと提案されたものであり、その目的は、断面方形状の定型ガスケットを使用しても気密性、防水性、防湿性、防塵性、等のシール性およびクッション性が確保できるシール部位のシール構造の提供にある。   The present invention has been proposed to solve such problems, and its purpose is to achieve sealing properties such as airtightness, waterproofness, moistureproofness, dustproofness, etc., even if a fixed gasket having a square cross section is used. Another object of the present invention is to provide a seal structure for a seal portion that can ensure cushioning properties.

前記課題を解決するため、この発明のシール部位のシール構造は、一方の部材と他方の部材のシール部位間に断面方形状の定型ガスケットを介在させてシールするシール構造であって、
一方の部材と他方の部材のシール部位のうち、いずれか一方のシール部位が傾斜していることを特徴とする。
これにより断面方形状の定型ガスケットであっても、一方の部材と他方の部材のシール部位のうち、いずれか一方のシール部位が傾斜しているので、定型ガスケットは方形状の角部から圧縮されることになり、ガスケットのシール部位への接触面積は小さくなるが、圧縮応力の調整が可能となる。従って、ガスケットのシール部位への接触面積が小さくても、良好な気密性、防水性、防湿性、防塵性、等のシール性およびクッション性を得ることができる。 In order to solve the above-mentioned problem, the seal structure of the seal part of the present invention is a seal structure for sealing with a fixed gasket having a rectangular cross section between the seal part of one member and the other member,
One of the sealing portions of the one member and the other member is inclined.
As a result, even in the case of a regular gasket having a square cross section, one of the seal portions of the member and the other member is inclined, so that the regular gasket is compressed from the square corner. As a result, the contact area of the gasket with the seal portion is reduced, but the compression stress can be adjusted. Therefore, even if the contact area of the gasket to the seal portion is small, it is possible to obtain good sealing properties such as airtightness, waterproofness, moisture resistance, dustproofness, and cushioning properties.

また、この発明の前記断面方形状の定型ガスケットは、一方の部材と他方の部材の、いずれか一方の部材のシール部位に接着されていることを特徴とする。
これにより前記作用の他に、定型ガスケットの位置が確保され、定型ガスケットがシール部位に方形の角部から確実に圧縮されることになる。 Further, the fixed gasket having a square cross section according to the present invention is characterized in that it is bonded to a seal portion of one member of one member and the other member.
As a result, in addition to the above-described operation, the position of the fixed gasket is ensured, and the fixed gasket is reliably compressed from the square corner to the seal portion.

また、この発明の前記一方の部材と他方の部材のシール部位は、ハードディスクドライブケースの筺体と蓋体のシール部位であることを特徴とする。
これにより断面方形状の定型ガスケットにおいて、ＨＤＤケースにおける筺体と蓋体間のシール部位の、気密性、防水性、防湿性、防塵性、等のシール性およびクッション性を確保することができる。 Further, the seal part of the one member and the other member of the present invention is a seal part of the housing and lid of the hard disk drive case.
Thereby, in the fixed gasket having a rectangular cross section, it is possible to ensure sealing properties such as airtightness, waterproofness, moisture proofing, dustproofness, etc. and cushioning properties of the sealing portion between the housing and the lid in the HDD case.

この発明のシール部位のシール構造によれば、次のような効果を奏する。
（１）断面方形状の定型ガスケットであっても、一方の部材と他方の部材のシール部位のうち、いずれか一方のシール部位が傾斜しているので、定型ガスケットは、方形状の角部から圧縮されることになり、圧縮応力の調整が可能となり、定型ガスケットのシール部位への接触面積が小さくなっても、良好な気密性、防水性、防湿性、防塵性、等のシール性およびクッション性を得ることができる。
（２）これにより定型ガスケットは、幅広のシート状のガスケット材の原板から打ち抜き形成した断面方形状の定型ガスケットのままでシール目的を向上させた使用が可能となり、製造が容易となり、しかも経済性が向上する。 According to the seal structure of the seal part of the present invention, the following effects can be obtained.
(1) Even in the case of a regular gasket having a square cross section, one of the seal portions of the member and the other member is inclined, so that the regular gasket is formed from a square corner. Compressive stress can be adjusted, and even if the contact area to the seal part of the standard gasket is reduced, it has good airtightness, waterproofness, moistureproofness, dustproofness, etc. Sex can be obtained.
(2) As a result, the fixed gasket can be used with improved sealing purposes as it is with a fixed gasket with a square cross-section punched out from a wide sheet-shaped gasket material, making it easy to manufacture and economical. Will improve.

（３）定型ガスケットがシール部位に接着されているので、定型ガスケットの位置が確保され、断面方形状の定型ガスケットの角部からシール部位に圧縮されるのが確実に保証される。
（４）断面方形状の定型ガスケットにおいて、ＨＤＤケースにおける筺体と蓋体間のシール部位の、気密性、防水性、防湿性、防塵性、等のシール性およびクッション性を良好に確保することができる。 (3) Since the fixed gasket is bonded to the seal portion, the position of the fixed gasket is secured, and it is reliably ensured that the fixed portion is compressed from the corner of the fixed gasket having a rectangular cross section to the seal portion.
(4) In a fixed gasket having a rectangular cross section, it is possible to ensure good sealing and cushioning properties such as airtightness, waterproofness, moistureproofness, dustproofness, etc., at the sealing part between the housing and the lid of the HDD case. it can.

この発明のシール部位のシール構造は、一方の部材と他方の部材のシール部位間に断面方形状の定型ガスケットを介在させてシールするシール構造であって、一方の部材と他方の部材のシール部位のうち、いずれか一方のシール部位が傾斜している。   The seal structure of the seal part of the present invention is a seal structure that seals with a fixed gasket having a rectangular cross section between the seal part of one member and the other member, and the seal part of one member and the other member Of these, one of the seal portions is inclined.

定型ガスケットは、一方の部材と他方の部材のシール部位間に介在すればよく、いずれか一方の部材のシール部位に接着（粘着）されていても、非接着でもよいが、位置が固定し、シール性が確実に確保される点で接着されているのが好ましい。この定型ガスケットの接着は、一方の部材と他方の部材の、いずれのシール部位であってもよく、傾斜しているシール部位でも、他方の水平面のシール部位でもよい。使用する対象のシール部位によって好ましい方を選択する。例えば、一方の部材と他方の部材のシール部位が、ＨＤＤケースの筺体と蓋体のシール部位である場合は、蓋体のシール部位を傾斜させ、この傾斜したシール部位に定型ガスケットを接着することを選択できる。   The fixed gasket may be interposed between the seal parts of one member and the other member, and may be adhered (adhered) to the seal part of any one member or non-adhered, but the position is fixed, It is preferable to adhere in terms of ensuring sealing performance. The fixed gasket may be bonded to any one of the sealing portions of the one member and the other member, and may be an inclined sealing portion or the other horizontal sealing portion. The preferred one is selected according to the seal site to be used. For example, when the seal part of one member and the other member is the seal part of the housing and lid of the HDD case, the seal part of the lid is inclined and the fixed gasket is bonded to the inclined seal part. Can be selected.

定型ガスケット材の密度および圧縮応力が、低すぎると柔軟になりすぎてガスケットの気密性、防水性、防湿性、防塵性、等のシール性およびクッション性、等が低下し、逆に高すぎると変形し難くなりシール面への追従性に欠け、それによりやはり気密性、防水性、防湿性、防塵性、等のシール性やクッション性が低下するので、この発明で便用する定型ガスケットのガスケット材は、このような点から好ましい密度および圧縮応力のものを選択する。例えば、ガスケット材は、密度が５０〜１０００ｋｇ／ｍ３のポリウレタン系の発泡体あるいは非発泡体を例示できる。密度が、５０ｋｇ／ｍ３未満では、柔軟になりすぎてガスケットの気密性、防水性、防湿性、防塵性、等のシール性やクッション性、等が低下し、逆に１０００ｋｇ／ｍ３を超えると変形し難くなりシール面への追従性に欠け、それによりやはり気密性、防水性、防湿性、防塵性、等のシール性やクッション性が低下するからである。従って、この発明の断面方形状の定型ガスケットは、例えば、密度が５０〜１０００ｋｇ／ｍ３のポリウレタン系のシート状ガスケット材の原板を作製し、この原板から図９に示すように打ち抜き形成することができる。 If the density and compressive stress of the standard gasket material are too low, the gasket will become too flexible, and the gasket's airtightness, waterproofness, moisture proofing, dustproofness, etc. will deteriorate, and if it is too high, Since it becomes difficult to deform and lacks the ability to follow the sealing surface, the sealing performance and cushioning properties such as airtightness, waterproofness, moistureproofness, dustproofness, etc. are also reduced. A material having a preferable density and compressive stress is selected from these points. For example, the gasket material can be exemplified by a polyurethane foam or non-foam having a density of 50 to 1000 kg / m 3 . Density is less than 50 kg / m 3, gasket tightness too flexible, waterproof, moisture-proof property, dust resistance, sealing property and cushioning property etc., etc. is lowered, more than 1000 kg / m 3 in the opposite This is because it becomes difficult to deform and lacks the ability to follow the sealing surface, and as a result, the sealing properties and cushioning properties such as airtightness, waterproofness, moistureproofness, and dustproofness are lowered. Accordingly, the regular gasket having a square cross section of the present invention is produced by, for example, producing a polyurethane-based sheet-like gasket material having a density of 50 to 1000 kg / m 3 and punching it from the original plate as shown in FIG. Can do.

この発明のシール部位のシール構造は、ガスケット材の原板から打ち抜き形成した断面方形状の定型ガスケットのままで、シール性を向上させた使用が可能であるし、一方の部材と他方の部材のシール部位のうち、一方のシール部位を傾斜させるだけであるので構造も簡単となり、ＨＤＤ等のＯＡ機器、携帯電話等の通信機器に適用して最適となる。
以下では、一方の部材と他方の部材のシール部位として、ＨＤＤケースの筺体と蓋体のシール部位においてシール構造の実施例を説明する。 The seal structure of the seal portion of the present invention can be used with a fixed gasket having a square cross section formed by punching from the gasket material original plate, and can be used with improved sealing performance, and the seal between one member and the other member Since only one of the seal portions is inclined, the structure is simple, and it is optimally applied to OA devices such as HDDs and communication devices such as mobile phones.
In the following, an embodiment of the seal structure will be described in the seal part of the housing and lid of the HDD case as the seal part of one member and the other member.

本例の、ＨＤＤケース１は、筺体２と蓋体３とより構成され、筺体２のシール部位２ａは、外側に向かって上り傾斜面に形成され、蓋体３のシール部位３ａは水平面となっており、断面方形状の定型ガスケット４は、蓋体３の水平面のシール部位３ａに接着されている場合である。従って、本例の定型ガスケット４は、図７（ｂ）に示すように筺体２のシール部位２ａである下り傾斜面に角部から接触し圧縮される。 7A and 7B are cross-sectional explanatory views of an HDD case showing Embodiment 7 of the present invention, in which FIG. 7A shows the open state, and FIG. 7B shows the closed state.
In this example, the HDD case 1 is composed of a housing 2 and a lid 3, the seal part 2 a of the housing 2 is formed in an upward inclined surface toward the outside, and the seal part 3 a of the lid 3 is a horizontal plane. In this case, the fixed gasket 4 having a square cross section is bonded to the horizontal seal portion 3 a of the lid 3. Therefore, the fixed gasket 4 of this example contacts and compresses from the corner | angular part to the downward inclined surface which is the seal | sticker site | part 2a of the housing 2, as shown in FIG.7 (b).

図８はこの発明の実施例８を示すＨＤＤケースの断面説明図であり、（ａ）が開蓋状態を示し、（ｂ）が閉蓋状態を示す。
本例は、ＨＤＤケース１の筺体２と蓋体３の構成は実施例７と同様であるが、断面方形状の定型ガスケット４が筺体２のシール部位２ａである下り傾斜面に接着されている場合である。従って、本例の定型ガスケット４は、図８（ｂ）に示すように蓋体３のシール部位３ａである水平面に角部から接触し圧縮される。 8A and 8B are cross-sectional explanatory views of an HDD case showing Embodiment 8 of the present invention, in which FIG. 8A shows an open state, and FIG. 8B shows a closed state.
In this example, the structure of the housing 2 and the lid 3 of the HDD case 1 is the same as that of the seventh embodiment, but the fixed gasket 4 having a square cross section is bonded to the downward inclined surface which is the seal part 2a of the housing 2. Is the case. Therefore, the fixed gasket 4 of this example contacts the horizontal surface which is the seal part 3a of the lid 3 from the corner as shown in FIG.

傾斜面の傾斜角θは、１０度〜７０度の範囲が好ましく、２０度〜４５度の範囲が特に好ましい。傾斜角θが１０度未満では、定型ガスケット４の断面方向での圧縮量の変化が少なく、圧縮応力の変化による調整効果が少なく、７０度を超えると、ＨＤＤケース１で蓋体３のシール部位３ａを傾斜面とする場合には、蓋体３と筺体２が当たってしまい充分に定型ガスケット４を圧縮できないからである。   The inclination angle θ of the inclined surface is preferably in the range of 10 degrees to 70 degrees, and particularly preferably in the range of 20 degrees to 45 degrees. When the inclination angle θ is less than 10 degrees, the amount of compression in the cross-sectional direction of the fixed gasket 4 is small and the adjustment effect due to the change in compression stress is small. This is because when the inclined surface 3a is used, the lid 3 and the casing 2 come into contact with each other and the fixed gasket 4 cannot be sufficiently compressed.

以上の説明から一方の部材と他方の部材のシール部位のうち、一方のシール部位を傾斜させる場合の傾斜角でも、１０度〜７０度の範囲がよく、特に、２０度〜４５度の範囲が好ましいことが理解でき、例えば、ＨＤＤケース１の蓋体３のシール部位３ａのように傾斜角が７０度を超えると蓋体３と筺体２が当たってしまう、というように実施する対象部材によって使用不可の範囲が個別に生ずる、ことが理解できる。従って、傾斜角は、実施する対象部材によって１０度〜７０度の範囲で適宜選択するのがよい。   From the above description, the inclination angle in the case of inclining one of the sealing portions of one member and the other member is preferably in the range of 10 degrees to 70 degrees, and particularly in the range of 20 degrees to 45 degrees. It can be understood that it is preferable, for example, it is used depending on the target member to be implemented such that when the inclination angle exceeds 70 degrees, as in the seal part 3a of the lid 3 of the HDD case 1, the lid 3 and the housing 2 will hit each other. It can be understood that the impossible range occurs individually. Therefore, the inclination angle may be appropriately selected within the range of 10 to 70 degrees depending on the target member to be implemented.
