Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure of a part mounting portion of a resin pipe with high sealability and enabling the secure and firm mounting of parts. <P>SOLUTION: A resin mounting port 2 is held by a metal restriction ring 3 and a connection port 9 and suppressed in deformation and reinforced. The restriction ring 3 is fitted onto the mounting port 2, engaged with an engagement part 2a, and firmly fixed to the resin pipe 1. The metal restriction ring 3 is firmly connected to the connection port 9 by using a fixing bolt 11. Thus, since the resin pipe 1, the restriction ring 3, and the connection port 9 are firmly fixed integrally with each other for less deformation, and the restriction ring 3 receives a reaction acting on an O-ring 8, the high sealability can be secured by eliminating a clearance between the inner peripheral surface of the mounting port 2 and the connection port 9. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、樹脂配管の部品取付け部構造に関し、さらに詳しくは、シール性が高く、確実かつ強固に部品の取付けが可能な樹脂配管の部品取付け部構造に関するものである。   The present invention relates to a component mounting part structure for resin piping, and more particularly, to a component mounting part structure for resin piping that has high sealing performance and enables reliable and strong component mounting.

近年、軽量化を図るためにエンジンのインテークマニホールドに樹脂が使用されるようになり（例えば、特許文献１参照）、また、燃料電池に使用される配管やマニホールドには、軽量化や内部を流通する流体によって金属イオンの溶出を防ぐ等の目的で、樹脂が使用されるようになり、樹脂配管の用途が広がりつつある。   In recent years, resin has been used in engine intake manifolds in order to reduce weight (see, for example, Patent Document 1), and in pipes and manifolds used in fuel cells, weight reduction and internal distribution are available. Resin is used for the purpose of preventing elution of metal ions by the fluid to be used, and uses of resin piping are expanding.

従来の樹脂配管におけるセンサ等の部品を取付ける構造は、例えば図４に示すような構造をしていた。この構造では、内周面にねじ溝を有し、樹脂配管１の内部と連通する連通孔４を有する取付け口２が樹脂配管１に突設され、この取付け口２にフランジ部９ａを有する筒状の金属製の接続ポート９が螺合されて固定されていた。接続ポート９には、樹脂配管１内を流通する流体の状態を検知する温度センサ、圧力センサ等の部品１２の一部が嵌着されて取付けられていた。   A conventional structure for mounting components such as sensors in resin piping has a structure as shown in FIG. 4, for example. In this structure, a mounting port 2 having a threaded groove on the inner peripheral surface and having a communication hole 4 communicating with the inside of the resin pipe 1 protrudes from the resin pipe 1, and a cylinder having a flange portion 9a in the mounting port 2 The metal connection port 9 was fixed by screwing. A part of a part 12 such as a temperature sensor or a pressure sensor for detecting the state of fluid flowing through the resin pipe 1 is fitted and attached to the connection port 9.

しかしながら、この構造では、樹脂製の取付け口２と金属製の接続ポート９との熱膨張率の違いによって、相互間にすき間が生じ、また、樹脂の経時的なクリープによって相互間にすき間が生じてシール性を確保できないという問題があった。   However, in this structure, a gap occurs between the resin attachment port 2 and the metal connection port 9 due to a difference in thermal expansion coefficient, and a gap occurs between the resin due to creep over time. As a result, there was a problem that the sealing performance could not be secured.

また、燃料電池のマニホールドのような樹脂配管では、内部を流通する流体に応じて使用できる樹脂が限定されるといった制約があり、高強度の樹脂が使用できない場合には、取付け口２に接続ポート９を強固に固定することができず、これに伴い、部品１２を確実、強固に樹脂配管１に取付けることができないという問題があった。   In addition, resin pipes such as fuel cell manifolds have a restriction that the resin that can be used is limited depending on the fluid flowing through the interior. When high-strength resin cannot be used, the connection port is connected to the attachment port 2. 9 cannot be firmly fixed, and accordingly, there is a problem that the component 12 cannot be securely and firmly attached to the resin pipe 1.

また、樹脂配管にセンサ等を取付けるための別の構造が提案されている（例えば、特許文献２参照）。この提案では、樹脂配管の外周部から外側にセンサが挿入される円筒部を膨出させ、この円筒部に周方向に形成されるスリットを設けて、円筒部に挿入されたセンサに設けられた溝部とスリットとに保持金具を嵌合させてセンサを円筒部に取付ける構造としている。   Another structure for attaching a sensor or the like to a resin pipe has been proposed (see, for example, Patent Document 2). In this proposal, a cylindrical portion into which a sensor is inserted is expanded from the outer peripheral portion of the resin pipe, and a slit formed in the circumferential direction is provided in the cylindrical portion, and the sensor is provided in the cylindrical portion. A holding metal fitting is fitted to the groove and the slit so that the sensor is attached to the cylindrical portion.

しかしながら、この構造では、円筒部にスリットを設けることによって、円筒部の剛性が低下し、部品を確実、強固に取付けるには不利な構造であった。
特開２００３−２５４１８１号公報 特開２００４−１７７２２３号公報 However, in this structure, providing the slit in the cylindrical portion reduces the rigidity of the cylindrical portion, which is a disadvantageous structure for securely and firmly attaching the components.

本発明の目的は、シール性が高く、確実かつ強固に部品の取付けが可能な樹脂配管の部品取付け部構造を提供することにある。   An object of the present invention is to provide a component mounting part structure for a resin pipe that has high sealing performance and enables reliable and strong component mounting.

上記目的を達成するため本発明の樹脂配管の部品取付け部構造は、樹脂配管に該樹脂配管内部と連通させて部品を取付けるための構造であって、前記樹脂配管の外周に突設され、前記樹脂配管内部と連通する連通孔を有する取付け口と、該取付け口の外周から突出する係合部と、該係合部に係合するとともに前記取付け口に外嵌される剛性のあるリング状の規制体と、フランジ部を有し前記部品が嵌着される剛性のある筒状の接続ポートとを備え、前記接続ポートは前記取付け口の内周面との間にＯリングを介在させて前記連通孔に嵌挿されるとともに、前記フランジ部が前記リング状の規制体に固定されることを特徴とするものである。   In order to achieve the above object, the resin pipe component mounting part structure of the present invention is a structure for mounting a component in a resin pipe in communication with the inside of the resin pipe, and projects from the outer periphery of the resin pipe. An attachment port having a communication hole communicating with the inside of the resin pipe, an engagement portion protruding from the outer periphery of the attachment port, and a rigid ring-like shape that engages with the engagement portion and is externally fitted to the attachment port A restricting body and a rigid cylindrical connection port having a flange portion to which the component is fitted, and the connection port includes an O-ring between the inner peripheral surface of the attachment port and the connection port. The flange portion is fixed to the ring-shaped regulating body while being inserted into the communication hole.

本発明の樹脂配管の部品取付け部構造によれば、樹脂配管の外周に突設され、樹脂配管内部と連通する連通孔を有する取付け口と、この取付け口の外周から突出する係合部と、この係合部に係合するとともに取付け口に外嵌される剛性のあるリング状の規制体と、フランジ部を有し部品が嵌着される剛性のある筒状の接続ポートとを備え、接続ポートは取付け口の内周面との間にＯリングを介在させて連通孔に嵌挿されるとともに、フランジ部がリング状の規制体に固定される構造としたので、樹脂製の取付け口が剛性のあるリング状の規制体と接続ポートとに挟まれて変形が抑制されるとともに、補強される構造となる。     According to the resin pipe component mounting portion structure of the present invention, a mounting port that protrudes from the outer periphery of the resin piping and has a communication hole communicating with the inside of the resin piping, and an engaging portion that protrudes from the outer periphery of the mounting port; A rigid ring-shaped restricting body that engages with the engaging portion and is externally fitted to the attachment port, and a rigid cylindrical connection port that has a flange portion and that is fitted with a component. The port is inserted into the communication hole with an O-ring interposed between the inner peripheral surface of the mounting port and the flange is fixed to the ring-shaped restricting body, so the resin mounting port is rigid. The structure is reinforced while being deformed by being sandwiched between the ring-shaped regulating body and the connection port.

リング状の規制体は、取付け口に外嵌され、取付け口の係合部と係合することによって、移動が抑えられるので、樹脂配管に対してリング状の規制体が強固に固定可能となる。また、リング状の規制体と接続ポートは、互いに剛性があり、固定ボルト等を用いて締結しても容易に変形せずに固定できるので、確実で強固に固定可能であり、これによって樹脂配管、リング状の規制体および接続ポートが一体的に強固に固定可能となり、変形しにくいものとなる。   Since the ring-shaped restricting body is externally fitted to the attachment port and engaged with the engaging portion of the attachment port, the movement is suppressed, so that the ring-shaped restricting member can be firmly fixed to the resin pipe. . In addition, the ring-shaped restricting body and the connection port are rigid to each other, and can be fixed without being easily deformed even when fastened with fixing bolts or the like, so that they can be fixed securely and firmly. The ring-shaped restricting body and the connection port can be firmly and integrally fixed, and are difficult to deform.

また、リング状の規制体がOリングに作用する反力を受けるので、取付け口の内周面と接続ポートとのすき間をなくして高いシール性を確保することができる。   In addition, since the ring-shaped restricting body receives a reaction force acting on the O-ring, the gap between the inner peripheral surface of the attachment port and the connection port can be eliminated to ensure high sealing performance.

このように、取付け口とのシール性が高く、強固に一体化して変形の少ない接続ポートに部品を取付けるので、高いシール性を保って、部品を確実、強固に取付けることが可能となる。   As described above, since the parts are attached to the connection port that has a high sealing property and is firmly integrated and less deformed, the parts can be securely and firmly attached while maintaining a high sealing property.

以下、本発明の樹脂配管の部品取付け部構造を図に示した実施形態に基づいて説明する。図１は実施形態の縦断面構造を示している。この樹脂配管１は、外周に樹脂配管１の内部と連通する連通孔４を有する取付け口２を突設し、取付け口２の上端には外側に突出するフランジ状の係合部２ａが設けられている。この樹脂配管１、取付け口２および係合部２ａは樹脂で一体成形されている。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a structure for mounting parts of resin pipes according to the present invention will be described based on the embodiments shown in the drawings. FIG. 1 shows a longitudinal sectional structure of the embodiment. The resin pipe 1 is provided with a mounting port 2 having a communication hole 4 communicating with the inside of the resin pipe 1 on the outer periphery, and a flange-like engaging portion 2 a protruding outward is provided at the upper end of the mounting port 2. ing. The resin pipe 1, the attachment port 2, and the engaging portion 2a are integrally formed of resin.

取付け口２には、この外周に密着するとともに、係合受部３ｄを係合部２ａと係合させる剛性のあるリング状の規制体として、金属製の規制リング３が嵌め込まれている。   A metal regulating ring 3 is fitted into the mounting port 2 as a rigid ring-shaped regulating body that is in close contact with the outer periphery and engages the engaging receiving portion 3d with the engaging portion 2a.

規制リング３が嵌め込まれた取付け口２の連通孔４には、上端にフランジ部９ａを有する筒状の金属製の接続ポート９が挿入され、介在するOリング８によって取付け口２の内周面と接続ポート９との間はシールされた状態となっている。   A cylindrical metal connection port 9 having a flange portion 9a at the upper end is inserted into the communication hole 4 of the mounting port 2 in which the restriction ring 3 is fitted, and the inner peripheral surface of the mounting port 2 by an intervening O-ring 8. The connection port 9 is sealed.

接続ポート９の上端のフランジ部９ａは、規制リング３の上面と当接し、ワッシャ１０を介装してフランジ部９ａに設けられた貫通孔９ｂを挿通し、規制リング３に設けられたボルト穴７に螺合する固定ボルト１１によって固定された構造となっている。   The flange portion 9a at the upper end of the connection port 9 is in contact with the upper surface of the restriction ring 3 and is inserted through a through hole 9b provided in the flange portion 9a with a washer 10 interposed therebetween. 7 is fixed by a fixing bolt 11 that is screwed onto the screw 7.

接続ポート９には、樹脂配管１の内部と連通する各種部品１２が取付けられる。例えば、樹脂配管１の内部を流通する流体の温度、圧力、流量、湿度、濃度等を感知するセンサが取付けられる。また、別の配管を取付けることもできる。   Various components 12 that communicate with the inside of the resin pipe 1 are attached to the connection port 9. For example, a sensor for sensing the temperature, pressure, flow rate, humidity, concentration, etc. of the fluid flowing through the resin pipe 1 is attached. Another pipe can be attached.

この構造では、樹脂製の取付け口２が、金属製の規制リング３および接続ポート９に挟まれて変形が抑制されるとともに補強されることになる。   In this structure, the resin attachment port 2 is sandwiched between the metal regulation ring 3 and the connection port 9 to suppress deformation and be reinforced.

規制リング３は、取付け口２の外周に密着して嵌め込まれ、規制リング３の係合受部３ｄは、取付け口２の上端の係合部２ａと係合することによって、規制リング３の移動を抑えるので、樹脂配管１に対して規制リング３が強固に固定可能となる。係合部２ａおよび係合受部３ｄの形状は、図１に示したものに限定されず、種々の形状を採用することができる。   The restriction ring 3 is fitted in close contact with the outer periphery of the attachment port 2, and the engagement receiving portion 3 d of the restriction ring 3 engages with the engagement portion 2 a at the upper end of the attachment port 2, thereby moving the restriction ring 3. Therefore, the regulation ring 3 can be firmly fixed to the resin pipe 1. The shapes of the engaging portion 2a and the engaging receiving portion 3d are not limited to those shown in FIG. 1, and various shapes can be adopted.

規制リング３と接続ポート９は、互いに金属製であり、固定ボルト１１を用いて固定しても容易に変形しないので、確実で強固な固定可能であり、これによって樹脂配管１、規制リング３および接続ポート９が一体化して強固に固定され、変形しにくい構造となる。規制リング３と接続ポート９との固定は、図１に示した固定ボルト１１に限定されず、他の固定手段を用いることができる。   Since the regulation ring 3 and the connection port 9 are made of metal and are not easily deformed even if they are fixed using the fixing bolts 11, they can be fixed securely and firmly. The connection port 9 is integrated and firmly fixed, and the structure is difficult to deform. The fixing of the restriction ring 3 and the connection port 9 is not limited to the fixing bolt 11 shown in FIG. 1, and other fixing means can be used.

また、Oリング８の半径方向外側に規制リング３が配置されているので、規制リング３がOリング８に作用する反力を受け、取付け口２の内周面と接続ポート９とのすき間をなくして高いシール性を確保することができる。   Further, since the regulating ring 3 is arranged on the outer side in the radial direction of the O-ring 8, the regulating ring 3 receives a reaction force acting on the O-ring 8, and the gap between the inner peripheral surface of the mounting port 2 and the connection port 9 is set. Without it, high sealing performance can be secured.

以上のように、取付け口２と高いシール性を保ちつつ、強固に一体化して変形が少ない接続ポート９に部品１２を取付けるので、高いシール性を保って確実、強固な取付けが可能となる。   As described above, since the component 12 is attached to the connection port 9 which is firmly integrated and has little deformation while maintaining high sealing performance with the mounting opening 2, it is possible to reliably and firmly attach while maintaining high sealing performance.

樹脂配管１は、内部を流通する流体によって耐食性、耐熱性等の要求性能を満す樹脂が使用されるため、必ずしも剛性の高い樹脂を使用できるとは限らない。例えば、燃料電池自動車に搭載される燃料電池のマニホールドは、軽量化が求められるとともに狭いスペースに収まるように複雑な形状となり、内部を流通する流体によって使用できる樹脂が限定され、制約が多くなる。   Since the resin piping 1 uses a resin that satisfies the required performance such as corrosion resistance and heat resistance depending on the fluid flowing through the inside thereof, it is not always possible to use a resin having high rigidity. For example, a fuel cell manifold mounted on a fuel cell vehicle is required to be light in weight and has a complicated shape so as to fit in a narrow space, and the resin that can be used is limited depending on the fluid flowing through the inside, resulting in many restrictions.

このように使用可能な樹脂に制約があり、剛性の低い樹脂によって樹脂配管１が形成される場合でも、本発明の構造であれば、部品１２を確実、強固に樹脂配管１に取付けることができ、高いシール性を確保することができる。換言すれば、部品１２を取付けるための剛性を考慮せずに配管に使用する樹脂を選択することができ、材料選択の幅を広げることが可能となる。   Even when the resin pipe 1 is formed of a resin having low rigidity, the resin 12 can be securely and firmly attached to the resin pipe 1 with the structure of the present invention. High sealing performance can be ensured. In other words, the resin used for the piping can be selected without considering the rigidity for mounting the component 12, and the range of material selection can be expanded.

規制リング３は金属製に限定されず、取付け口２の変形を規制でき、固定ボルト１１による固定によって容易に変形しない剛性のある材質を用いることができ、例えば、ポリアミド、ポリブチレンテレフタレート、ポリエチレンテレフタレート、ポリアセタール、変性ポリフェニレンエーテル、ポリサルフォン、ポリフェニレンサルファイド、ポリアリレート、熱可塑性ポリイミド、ポリアミドイミド、ポリエーテルイミド、ポリエーテルエーテルケトン等の樹脂や、それらをガラス繊維、カーボン繊維等で複合強化した樹脂、また、セラミック等を使用することができる。   The restriction ring 3 is not limited to a metal, and can be made of a rigid material that can restrict the deformation of the mounting port 2 and is not easily deformed by fixing with the fixing bolt 11. For example, polyamide, polybutylene terephthalate, polyethylene terephthalate , Resins such as polyacetal, modified polyphenylene ether, polysulfone, polyphenylene sulfide, polyarylate, thermoplastic polyimide, polyamideimide, polyetherimide, polyetheretherketone, and resins reinforced with composites such as glass fiber and carbon fiber, Ceramic or the like can be used.

接続ポート９も金属製に限定されず、部品１２の取付けや固定ボルト１１による固定によって容易に変形しない材質として、規制リング３と同様に上記した材質を使用することができる。   The connection port 9 is not limited to metal, and the material described above can be used in the same manner as the restriction ring 3 as a material that is not easily deformed by the attachment of the component 12 or the fixing by the fixing bolt 11.

規制リング３は、樹脂配管１を射出成形する際に、金型にインサートしておき、図２に示すように樹脂配管１と一体化することもできる。これによって、取付け口２と規制リング３とを強固に密着して接合することができる。この構造によれは、別途、接続ポート９を組み付けるだけでよいので、組立工数を削減することが可能となる。   When the resin pipe 1 is injection-molded, the regulating ring 3 can be inserted into a mold and integrated with the resin pipe 1 as shown in FIG. As a result, the attachment port 2 and the regulating ring 3 can be firmly adhered and joined. According to this structure, it is only necessary to assemble the connection port 9 separately, so that the number of assembling steps can be reduced.

尚、図２に示すようにフランジ状の係合部２ａの外縁に凹部２ｂを設ける等によって、係合部２ａの外縁を非円形にすることによって、取付け口２と規制リング３との回転ずれを防止することができる。   In addition, as shown in FIG. 2, by providing the outer edge of the engaging portion 2a with a non-circular shape by providing a concave portion 2b on the outer edge of the flange-like engaging portion 2a, the rotational deviation between the mounting port 2 and the regulating ring 3 is achieved. Can be prevented.

規制リング３は、周方向に複数に分割した分割体を組み付けて構成することもできる。例えば、図３に示すように、規制リング３を２つの分割体３ａ、３ｂとし、対向する一端部をヒンジ部６で連結し、それぞれの他端部に貫通孔５ａを有する接合片５を設け、それぞれの貫通孔５ａ、５ａにボルト等を挿通させて両接合片５、５を当接させてリング状に連結して構成することもできる。分割数やリング状にする連結手段は、図示したものに限定されず適宜、決定することができる。   The restriction ring 3 can also be configured by assembling a plurality of divided bodies divided in the circumferential direction. For example, as shown in FIG. 3, the regulating ring 3 is divided into two divided bodies 3a and 3b, one end portions facing each other are connected by a hinge portion 6, and a joining piece 5 having a through hole 5a at each other end portion is provided. Alternatively, a bolt or the like may be inserted into each of the through holes 5a and 5a so that both the joining pieces 5 and 5 are brought into contact with each other and connected in a ring shape. The number of divisions and the connecting means for making the ring shape are not limited to those shown in the figure, and can be determined as appropriate.

この規制リング３の構造では、取付ける部品１２等に応じて、適切な材質や形状等の規制リング３を選択して取付け口２の外周に嵌め込むことができる。   In the structure of the restriction ring 3, the restriction ring 3 having an appropriate material or shape can be selected and fitted into the outer periphery of the attachment port 2 according to the part 12 to be attached.
