Description

【考案の詳細な説明】[Detailed description of the invention]

【0001】[0001]

【考案の属する技術分野】[Technical field to which the invention belongs]

この考案は、高密度半導体チップ製造現場等におけるクリーンルーム内で用い る純水等洗滌液、その他一般薬液等の流管路を司るフッ素樹脂製チューブの継手 として好適なチューブ継手に関する。 The present invention relates to a tube joint suitable as a joint for a fluororesin tube that controls a flow path of a cleaning liquid such as pure water used in a clean room at a high-density semiconductor chip manufacturing site or the like, and other general chemical liquids.

【0002】[0002]

【従来の技術】[Prior art]

この種のチューブ継手としては、従来、例えば実開平4−122882号公報 記載のものが有る。 As a tube joint of this type, there is a tube joint described in, for example, Japanese Utility Model Laid-Open No. 4-122882.

【0003】 この従来の技術は、チューブに変形部分を形成することで抜け止めを施したチ ューブ継手において、フッ素樹脂製のチューブの端部に外鍔と大径部とを形成す るとともに、前記大径部内に溝環を有する継手本体の挿着筒を挿入し、また前記 大径部に遊挿したリングの大部分を前記溝環内に挿入して前記継手本体の雄ネジ 部に螺入した袋ナットで前記リングを外鍔にきつく圧接することでチューブの抜 け止めを施すとともに、袋ナットの肩部の内面で前記チューブの中間部分を前記 挿着筒の端面にきつく圧接してチューブ屈折部を形成してなるチューブ継手であ る。According to this conventional technique, in a tube joint in which a deformed portion is formed in a tube to prevent the tube from coming off, an outer collar and a large diameter portion are formed at the end of the tube made of fluororesin, and Insert the insertion tube of the joint body having the groove ring in the large diameter portion, and insert most of the ring loosely inserted in the large diameter portion into the groove ring to screw it into the male screw portion of the joint body. Prevent the tube from coming off by pressing the ring tightly against the outer collar with the inserted cap nut, and press the middle part of the tube tightly against the end face of the insertion tube with the inner surface of the shoulder of the cap nut. It is a tube joint formed by forming a tube bending portion.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

この従来の技術におけるチューブに変形部分を形成するための熱作業の工程は 2回必要であり、時間がかかっていたし、加熱対流で加熱むらが起こると、外鍔 の形状が均等にならなくなり、締め付け時にアンバランスが起きて、安定な締め 付けができない場合があり、加熱に対する熟練が必要であった。 The process of heat work for forming a deformed portion in the tube in this conventional technique requires two times and takes time, and when heating unevenness occurs due to heating convection, the shape of the outer collar becomes uneven, There was a case where imbalance occurred during tightening, and stable tightening could not be achieved, so it required skill for heating.

【0005】 また、大径部を形成した後、金型を外して時間が経つとチューブ屈折部が徐々 に縮んできてしまい、挿着筒に充分入り込まなくなるので、大径部に熱が残って いるうちに素早く継手の挿着筒に押し込まなければならないので、機敏な作業が 必要であるという多くの問題点が有った。Also, after forming the large-diameter portion, when the mold is removed and time passes, the tube bending portion gradually contracts and does not sufficiently enter the insertion tube, so that heat remains in the large-diameter portion. Since it had to be quickly pushed into the fitting insertion tube while it was in progress, there were many problems that agile work was required.

【0006】 この他に実開昭62−86489号公報記載のもののように、チューブに先細 の拡径部を形成してその内側に保形リングを圧入し、拡径部斜面を袋ナットの斜 面部で継手本体に締め付けることでチューブの抜け止めを施したチューブ継手も 周知である。 ところが、この従来例は、チューブ拡径部とチューブとの連接屈折部分を継手 本体に締め付ける手段がないので、高温で継手からチューブやパイプが抜け易く 、しかも、継手としての気密液密性に乏しく、特に、チューブがフッ素樹脂製チ ューブのように外面滑性が大きい素材であるときは、チューブ抜けが多発すると 共に、袋ナットの経時的『ユルミ』も大となる。In addition to this, as described in Japanese Utility Model Laid-Open No. 62-86489, a tapered expanded portion is formed in a tube, and a shape-retaining ring is press-fitted inside the expanded portion, and the inclined surface of the expanded portion is slanted on the cap nut. A tube joint in which the tube is prevented from coming off by tightening the surface of the joint body is also well known. However, in this conventional example, since there is no means for tightening the joint refraction part of the tube expanded portion and the tube to the joint body, the tube or pipe can easily come out of the joint at high temperature, and the airtight liquid tightness of the joint is poor. Especially when the tube is made of a material with a large outer surface such as a tube made of fluororesin, the tube often comes off, and the "nut" of the cap nut over time also becomes large.

【0007】 さらに、この従来例を初めとして前記実開平4−122882号公報記載の従 来例は、高温下の使用中、使用時間の経過に伴い、筒体とかリングやチューブが 変形し、チューブ内面と他の部材との接面部分にスキマが生じる結果、僅かな液 溜りが生じて、いわゆる『死水』が貯溜したり、研摩用微細粒子が上記変形スキ マ部に引掛って堆積成長し、チューブが径小化してしまうという問題点が有った 。Furthermore, in the conventional example described in the above-mentioned Japanese Utility Model Laid-Open No. 4-122882, the tubular body, the ring, and the tube are deformed with the passage of time during use at high temperature, and the tube As a result of a gap occurring at the contact surface between the inner surface and another member, a small amount of liquid pool is created, so-called "dead water" is stored, and fine particles for polishing are caught in the deformed gap part and grow up. However, there was a problem that the diameter of the tube was reduced.

【0008】 この考案は、前記した各問題点を除去するために、継手本体の溝環に挿入した チューブ拡径部を袋ナットで継手本体にきつく締め付けることで、前記チューブ 拡径部に連接したチューブ屈折部を袋ナットの鋭角孔縁で継手本体の筒状部の鋭 角尖端にきつく圧接してチューブ抜け止め部と気密保持部とし、かつ、前記筒状 部尖端5Aの内周面を液溜り防止用面取り斜面5Bとすることで、死水溜りをな くすることを目的とする。In order to eliminate the above-mentioned problems, the present invention connects the expanded diameter portion of the tube inserted in the groove ring of the joint body to the expanded diameter portion of the tube by tightly tightening the cap nut with the joint main body. The tube bending portion is tightly pressed against the sharp tip of the tubular portion of the joint body with the sharp hole edge of the cap nut to form the tube retaining portion and the airtight holding portion, and the inner peripheral surface of the tubular tip 5A is liquid. The purpose is to eliminate dead water pools by forming chamfered slopes 5B for pooling prevention.

【0009】[0009]

【課題を解決するための手段】[Means for Solving the Problems]

上記したこの考案の目的は、フッ素樹脂製チューブの端部付近にチューブ拡径 部を形成してその屈折部を袋ナットで継手本体に締め付けることでチューブの抜 け止めを施すに当たり、チューブの拡径部の内周面に溝環を有する硬質樹脂製継 手本体の筒状部を挿入すると共に、前記チューブ拡径部の大部分を前記溝環内に 挿入し、この溝環の外側における継手本体の雄ねじ部に螺入した硬質の袋ナット でチューブ屈折部を袋ナットの肩部に鋭角形成した孔縁で継手本体の筒状部の尖 端にきつく圧接することで、チューブ抜け止め部と気密保持部とを形成するとと もに、前記筒状部尖端の内周面を変形防止用面取り斜面となしたことで達成でき た。 The above-mentioned object of the present invention is to expand the tube in order to prevent the tube from being pulled out by forming a tube expanded part near the end of the fluororesin tube and tightening the bent part to the joint body with a cap nut. While inserting the tubular part of the hard resin joint body that has a groove ring on the inner peripheral surface of the diameter part, insert most of the tube expanded diameter part into the groove ring, and insert the joint on the outside of this groove ring. With a hard cap nut screwed into the male thread of the main body, the tube bend part is tightly pressed against the tip of the tubular part of the joint body with a hole edge that forms an acute angle on the shoulder of the cap nut to form a tube retaining part. This can be achieved by forming an airtight holding portion and forming a chamfered slope for preventing deformation on the inner peripheral surface of the tip of the tubular portion.

【考案の実施の形態】[Embodiment of the invention]

本考案の実施の形態例について図面を参照して説明する。 先ず、この考案の基本形態は、図1から図5までの各図に示すように、ポリ・ テトラ・フルオロ・エチレン(PTFE)とか、通常PFAと称するフッ素樹脂 製チューブ1の端部付近を加熱した拡径治具Aに図2のように強引に圧入してチ ューブ拡径部2を作る。 An embodiment of the present invention will be described with reference to the drawings. First, as shown in each of FIGS. 1 to 5, the basic form of the present invention is to heat the vicinity of the end of a fluororesin tube 1 called polytetrafluorofluoroethylene (PTFE) or PFA. As shown in FIG. 2, the tube expanding portion 2 is forcibly press-fitted into the expanding jig A.

【0011】 そして、このチューブ拡径部2の内周面に図3のように溝環3を有するフッ素 樹脂やポリプロピレン等の硬質樹脂製継手本体4の筒状部5を図4のように挿入 すると同時に前記チューブ拡径部2の大部分を前記溝環3内に挿入する。Then, the tubular portion 5 of the joint body 4 made of a hard resin such as fluororesin or polypropylene having the groove ring 3 as shown in FIG. 3 is inserted into the inner peripheral surface of the expanded tube portion 2 as shown in FIG. At the same time, most of the tube expanded portion 2 is inserted into the groove ring 3.

【0012】 次いで、この溝環3の外側における継手本体4の雄ねじ部4aに図4、図5の ように螺入したフッ素樹脂やポリプロピレンなどで作った硬質の袋ナット6で前 記チューブ拡径部2に連接したチューブ屈折部2aをその外面から袋ナット6の 肩部6Aに鋭角形成した孔縁6aで継手本体4の筒状部5の鋭角尖端5Aに同図 5および図1のようにきつく圧接して、チューブ抜け止め部と気密保持部とを形 成する。[0012] Next, as shown in Figs. 4 and 5, a hard cap nut 6 made of fluororesin or polypropylene screwed into the male screw portion 4a of the joint body 4 on the outside of the groove ring 3 is used to expand the tube diameter. As shown in FIG. 5 and FIG. 1, the tube bending portion 2a connected to the portion 2 is formed on the shoulder portion 6A of the cap nut 6 at an acute angle from the outer surface thereof to the sharp edge 5A of the tubular portion 5 of the joint main body 4 by the hole edge 6a. The tube is tightly pressed to form the tube retainer and the airtight retainer.

【0013】 また、前記筒状部尖端5Aの内周面には、予じめ、変形防止用面取り斜面5B を形成して、尖端5A付近に薄肉部が生じないようにすることで、その内側曲り 変形を防ぎ、チューブ間とのスキマの発生を防いで液溜りが生じない図1のよう な本考案によるチューブ継手を構成できた。In addition, a chamfered chamfer 5B for preventing deformation is formed on the inner peripheral surface of the tip 5A of the tubular portion so that a thin portion is not formed near the tip 5A. A tube joint according to the present invention as shown in Fig. 1 was constructed in which bending deformation was prevented, gaps between tubes were prevented from occurring, and liquid pool did not occur.

【0014】[0014]

【実施例】【Example】

前述した各構成部材の材質は、チューブ1および継手本体4内を流動する流体 の種類に応じて適宜定めることができ、比較的にラフな使用条件下で実施する場 合は、チューブ1を除く他の部材を金属等の強靭材で形成すれば、その強度も大 となる。 また、超高密度半導体チップ製造現場のように、シビアな使用条件下で実施す る場合は、チューブ1を初めとして、各構成部材のすべてをPTFEまたはPF Aのようなフッ素樹脂で作ることで、高密度の超LSI(大規模集積回路)チッ プの製造時における半導体チップの洗滌液の流管路として充分対処できた。 The material of each component described above can be appropriately determined according to the type of fluid flowing in the tube 1 and the joint main body 4, and the tube 1 is excluded when carrying out under relatively rough use conditions. If the other member is formed of a tough material such as metal, the strength thereof is also increased. In addition, when carrying out under severe operating conditions, such as in ultra-high-density semiconductor chip manufacturing sites, all of the components including the tube 1 are made of fluororesin such as PTFE or PFA. , It could be used as a flow path for cleaning liquid of semiconductor chips when manufacturing high-density VLSI chips (large-scale integrated circuits).

【考案の効果】[Effect of the invention]

この考案は、以上のような形態を採用したので、以下に記載の効果を奏する。 継手本体4の溝環3に挿入したチューブ屈折部2aをその外面から袋ナット6 で継手本体4の筒状部5にきつく締め付けることで、前記チューブ屈折部2aを 袋ナット6の肩部6Aに鋭角形成した孔縁6aで継手本体4の筒状部5の尖端5 Bにきつく圧接して厳重なチューブ抜け止め部と気密保持部を形成できたので、 チューブ1は、継手本体4に対し、気密・液密を厳重に保ち、継手本体4に密着 結合しており、妄りに緩んだり、引き抜けることがなく、長期に亘り安全に使用 できたという第1の効果が有る。 Since the present invention adopts the above-described embodiment, the following effects can be obtained. The tube bending portion 2a inserted into the groove ring 3 of the joint body 4 is tightly tightened from its outer surface to the tubular portion 5 of the joint body 4 with the cap nut 6, so that the tube bending portion 2a is attached to the shoulder portion 6A of the cap nut 6. Since the sharp edge 5a of the tubular portion 5 of the joint body 4 was tightly pressed by the sharply formed hole edge 6a to form the strict tube retaining portion and the airtight holding portion, the tube 1 was It has a first effect that it can be used safely for a long period of time without being loosened or pulled out inadvertently because it is tightly air-tight and liquid-tight and tightly connected to the joint body 4.

【0016】 また、特に本発明では、継手本体4の筒状部尖端5Aの内周面に変形防止用面 取り斜面5Bを形成したので、高温下で使用しても、その温度サイクル等で筒状 部尖端付近の内向き曲り変形を防止でき、いわゆる死水溜りをなくすることがで きたので、純水等洗浄液を汚染もなく、超高密度LSIチップ成品の洗滌ルート に安心して適用できたという工業的効果も有る。Further, particularly in the present invention, since the chamfered slope 5B for preventing deformation is formed on the inner peripheral surface of the tip portion 5A of the tubular portion of the joint body 4, even if it is used at a high temperature, the tubular body may be subjected to a temperature cycle or the like. Since it is possible to prevent inward bending deformation near the tip of the shape and eliminate so-called dead water pool, cleaning solution such as pure water is not contaminated and it can be safely applied to the cleaning route of ultra-high density LSI chip products. There is also an industrial effect.
