【発明の属する技術分野】
本発明は、雄部材(オスコネクター)と雌部材(メスコネクター)との嵌合構造、および該嵌合構造に使用する雌部材(メスコネクター)に関する。
【0002】
【従来の技術】
雄部材(オスコネクター)と雌部材(メスコネクター)との嵌合構造を形成する雄部材(オスコネクター)および雌部材(メスコネクター)としては、従来、図1に示すような外面部がテーパーを形成した雄部材(オスコネクター)、雌部材(メスコネクター)としては、内腔形状がスムースなテーパー形状の雌部材(メスコネクター)が知られているが、このような嵌合構造は、前記雄部材(オスコネクター)と雌部材(メスコネクター)の接合面が面接触であるため、嵌合部に油などが付着した場合、該接合部に油膜が介在することになるため滑りが発生しやすくなる。
【0003】
前記問題を解決するために、図1に示すようなスムースなテーパー形状の雄部材(オスコネクター)に代えて、雄部材(オスコネクター)として図2に示すような複数の台形部分で構成されるタケノコ状の段部を有するコネクターが提案されている。このコネクターは長軸方向に各段部の突縁部を結んだ形状が長軸方向先端部に向かってスムースなテーパー形状(先細形状)になるように形成されている。
【0004】
前記形タケノコ状コネクターは、雌部材(メスコネクター)の内腔に挿入するときは容易であり、逆に抜ける方向に力が作用する場合には、摩擦が増加して抜け難くなる、という利点を有するものである。しかし、このタケノコ状コネクターを成形するためには、金型を割型にする等の特有の(スライド)構造にする必要があり、手間やコストが増大し、さらには金型取数が制限され、生産性を減少させる等の課題が存在した。
【0005】
また、前記問題を解決するために、内腔形状がスムースなテーパー形状の雌部材(メスコネクター)に代えて、内腔面に円周リブが形成された雌部材(メスコネクター)が提案されている。しかしながら、この内腔面に円周リブが形成された雌部材(メスコネクター)は金型の機構上、寸法が安定せず、また、前記従来公知のタケノコ形状の雄部材(コネクター)と嵌合させた場合、それぞれの突起がマイナスに作用し、リークが発生する場合がある。
【0006】
【発明が解決しようとする課題】
本発明の目的は、前記問題を解決した嵌合構造、特に
雄部材(オスコネクター)と雌部材(メスコネクター)の嵌合構造において、(1)その嵌合力が滑性促進剤や水の付着によって低下した場合でも嵌合力を維持することが可能な嵌合構造、
(2)前記嵌合構造に使用される成型品寸法のばらつきが小さくなり、安定した嵌合が得られ、かつ該雄部材(オスコネクター)の外面部の形状に嵌合性が影響を受けることが少なく、種々の外面部の形状を有する雄部材(オスコネクター)、例えば外面部がタケノコ状、あるいは滑らかなテーパー状の雄部材(オスコネクター)とも安定した嵌合構造を形成できる雌部材(メスコネクター)、
を提供することにある。
【0007】
【課題を解決するための手段】
本発明の第1は、雄部材(オスコネクター)と雌部材(メスコネクター)との嵌合構造であって、前記雌部材(メスコネクター)が中空の円柱状部材であって、かつ、該中空円柱状部材の内腔の形状を、先端側になるに従って径が階段状に縮小する構造であることを特徴とする雄部材(オスコネクター)と雌部材(メスコネクター)との嵌合構造を提供することにより、前記課題を解決することができた。
前記雄部材(オスコネクター)の先端側には開口部を形成させ、かつ円柱状突起部材全体に内腔を形成し、液体、あるいは気体が流通可能となるように中空形状としても良い。
【0008】
本発明の第2は、前記第1の嵌合構造において、雌部材(メスコネクター)の隣り合う階段状段差間が、スムースなテーパー形状であることを特徴とする嵌合構造に関する。
【0009】
本発明の第3は、内腔の形状が、先端側になるに従って径が階段状に縮小する円筒体または導管である中空状部材であって、前記内腔内に雄部材(オスコネクター)が嵌挿された嵌合構造を形成することが可能なことを特徴とする雌部材(メスコネクター)に関する。
【0010】
本発明の第4は、前記雌部材(メスコネクター)において、隣り合う階段状段差間をスムースなテーパー形状としたことを特徴とする雌部材(メスコネクター)に関する。
【0011】
前記本発明で採用する雌部材(メスコネクター)は、従来公知の内腔面に円周リブが形成された雌部材(メスコネクター)に比較して、成型品自体の寸法のばらつきが小さくなり、安定した嵌合が得られ、かつ該雄部材(オスコネクター)の外面部の形状によって受ける嵌合性の影響が少ないので、例えば従来公知の外面部がタケノコ状、あるいはテーパー状の雄部材(オスコネクター)とも安定した嵌合構造を達成することができる。
【0012】
また、本発明の嵌合構造で採用する前記雌部材(メスコネクター)は、本出願人が先に提出した出願(特願2002−65367号)で提案した外面部が、先端側になるに従って径が縮小する複数の円柱状部分から形成される段部を有する雄部材(オスコネクター)とも安定した嵌合構造を達成することができる。
【0013】
従来公知の雄部材(オスコネクター)と雌部材(メスコネクター)の嵌合の場合、特に滑らかなテーパー面を有する雄部材(オスコネクター)と雌部材(メスコネクター)の嵌合の場合、接合面全体に滑性促進剤による摩擦低減層が生成する。例えば、滑性促進剤が油分の場合、油膜による摩擦低減層が接合面全体に生成し、雄部材(オスコネクター)と雌部材(メスコネクター)が抜去し易くなる。これに対して、前記のような本発明の嵌合構造においては、雌部材(メスコネクター)の内腔に形成した階段状の段差部分が、従来公知の内腔に設けた円周リブと同様な機能を有し、滑らかなテーパー面を有する雄部材(オスコネクター)との嵌合構造においても、該嵌合構造の場合に生じる摩擦低減層の広がりを分断することができる。その結果、従来公知のテーパー状に形成された雄部材(オスコネクター)と前記雌部材(メスコネクター)との嵌合の場合に、接合部位に滑性促進剤が付着した場合に発生していた嵌合力の著しい低下は抑制され、安定した接合力を保持できる。
【0014】
【発明の実施の態様】
以下、本発明を実施の態様に基づいて、さらに具体的に説明する。
実施態様1
本実施態様の雌部材(メスコネクター)は、内腔の形状が図3に示すように先端側になるに従って径が階段状に縮小するように階段状部分a,b,c,dを有する円筒体または導管である中空状雌部材(メスコネクター)4である。
本実施態様の雌部材(メスコネクター)は、その内腔を先端側になるに従って径が階段状に縮小する形状とすることにより、アンダーカット部分がなくなるため、成形時の際の変形が起こり難くなり、成形寸法が安定し成形品寸法のばらつきが小さくなるので、雄部材(オスコネクター)と安定した嵌合構造が得られる。
【0015】
実施態様2
本実施態様の雌部材(メスコネクター)は、図4に示すように前記実施態様1の雌部材(コネクター)4において、階段状部分a,b,c,dの隣り合う段差間をスムースなテーパー形状部分fとしたことを特徴とするな雌部材(コネクター)5である。この雌部材(メスコネクター)5は、段差と段差の間のスムースなテーパー形状部分fがスムースなテーパー形状の雌部材(メスコネクター)のテーパー面と同様な効果をもたらす。また、本実施態様の雌部材(メスコネクター)は図2に示す公知のタケノコ形状の雄部材(コネクター)と嵌合させる場合、該メス部材のa、b、c、d部分とタケノコ状の突起部分が互いに確実に嵌合することが可能となり、安定した嵌合が得られる。また、階段状とすることで、前記実施態様1と同様にアンダーカット部分がなくなるため、成形時の際の変形が起こり難くなり、成形寸法が安定し成形品寸法のばらつきが小さくなり、安定した嵌合構造が得られる。
【0016】
実施態様3
図5に示す本実施態様の嵌合構造7は、前記図3に示す実施態様1の雌部材(メスコネクター)4の内部に、図1に示す外面部が滑らかなテーパー形状の雄部材(オスコネクター)1を挿嵌した場合の嵌合構造を示す図である。
本実施態様の嵌合構造は、前記実施態様1の雌部材(メスコネクター)の内腔に形成された階段条部分a,b,c,dが、該階段条部分突縁部1a,1b,1c,1dで前記雄部材(オスコネクター)と部分的に接合し、かつ前記階段状部分a,b,c,dが従来公知の円周リブ形状を内腔に設けた雌部材(メスコネクター)の円周リブ形状と同様の効果をもたらす。したがって、滑性促進剤が両コネクターの接合面に付着した場合にも、滑性促進剤の接合面全体への広がりを抑制できる結果、嵌合力の著しい低下を防止できる。また、前記のように雌部材(メスコネクター)の内腔を階段状部分a,b,c,dで構成される階段状とすることで、アンダーカット部分がなくなるため、成形時の際の変形が起こり難くなり、成形寸法が安定し成形品寸法のばらつきが小さくなり、安定した嵌合構造が得られる。
【0017】
実施態様4
図6は本出願人が先に出願した(特願2002−65367)の複数の段付き円柱状突起部材8a〜8eを有する雄部材(コネクター)8に関するものであって、本発明の嵌合構造に使用することができるものである。
前記円柱状突起部材8は先端側になるにつれて径の縮小する複数の縮径円柱が形成され、長手方向にテーパー形状のものであり、また、内腔には液あるいは気体の通過できるように通路10が形成されている。そして、各縮径円柱の長手方向の外壁面は雄部材(オスコネクター)の軸に対して実質的に平行である。この縮径円柱の外壁部が実質的に軸に平行なものは、成形上容易であり、かつ嵌合力保持や挿入性の点においても優れている。
【0018】
また、前記雄部材(オスコネクター)は、隣接する各縮径円柱の先端側縁部を結んだ場合に想定されるテーパー角度が12.5±3.0/100のものが好ましい。このようなテーパー角度を持つ段差構造とすることにより、雌部材(メスコネクター)に挿入する時には挿入が容易で、しかも抜去する際に所定の引張力が必要なため、不測の事態によって簡単に離脱することが防止できる。すなわち、前記雄部材(オスコネクター)の段付き円柱状突起が、段差の小さい段付き円柱状突起であると、両コネクターの接合面に滑性促進剤が付着した場合、滑性促進剤が接合面全体に拡がりやすいので、摩擦力の低下防止において効果が少なく、逆に段差が大き過ぎると接合面積そのものが小さくなって離脱し易くなる。
さらに、本実施態様の雄部材(オスコネクター)8は、図2に示すようなタケノコ状の雄部材(オスコネクター)に比較して成形し易く、生産性が向上し、製造コストを下げることができる。また、本実施の態様の雄部材(オスコネクター)8は、その内部に通路1が形成されたものであるが、前記通路1が形成されず、単にコネクター機能を有するものであっても良い。
【0019】
前記雄部材(オスコネクター)8は医療用注射器のシンリンジ(外筒)9の先端部に一体的に形成されている。この雄部材(オスコネクター)8が形成された医療用注射器は、前記雄部材(オスコネクター)8は本発明の雌部材(メスコネクター)、例えば前記実施態様1の雌部材(メスコネクター)に挿嵌されて使用される。そして、この嵌合構造は、前記実施態様1で述べたように雌部材(メスコネクター)4による種々の優れた効果を奏することができるだけでなく、注射器は上述のように雄部材(オスコネクター)8が成形し易いため、注射器自体も成形し易く、生産性が向上し、さらに製造コストも低減できる。
【0020】
【発明の効果】
本発明は、雄部材(オスコネクター)と雌部材(メスコネクター)の嵌合構造嵌において、
(1)その嵌合力が滑性促進剤や水の付着によって低下した場合でも嵌合力を維持することが可能な嵌合構造を達成でき、
(2)前記嵌合構造に使用される成型品寸法のばらつきが小さくなり、安定した嵌合構造を実現でき、かつ雄部材(オスコネクター)の外面部の形状に嵌合性が影響を受けることが少ない、例えば外面部がタケノコ状、あるいはテーパー状の雄部材(オスコネクター)とも安定した嵌合構造を形成する雌部材(メスコネクター)を提供することができた。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fitting structure between a male member (male connector) and a female member (female connector), and a female member (female connector) used for the fitting structure.
[0002]
[Prior art]
Conventionally, as a male member (male connector) and a female member (female connector) forming a fitting structure between a male member (male connector) and a female member (female connector), the outer surface as shown in FIG. As the formed male member (male connector) and female member (female connector), a tapered female member (female connector) having a smooth inner lumen shape is known. Since the joining surface between the member (male connector) and the female member (female connector) is in surface contact, if oil or the like adheres to the fitting portion, an oil film will intervene in the joining portion, so that slippage easily occurs. Become.
[0003]
In order to solve the above-mentioned problem, a male member (male connector) having a plurality of trapezoidal portions as shown in FIG. 2 is used instead of the male member (male connector) having a smooth tapered shape as shown in FIG. A connector having a bamboo-shaped step has been proposed. This connector is formed such that the shape connecting the protruding edges of the steps in the long axis direction has a smooth tapered shape (tapered shape) toward the front end portion in the long axis direction.
[0004]
The bamboo-shaped connector has the advantage that it is easy to insert into the lumen of a female member (female connector), and when force acts in the direction of removal, friction increases and it becomes difficult to remove. Have However, in order to form this bamboo-shaped connector, it is necessary to use a special (slide) structure such as splitting the mold, which increases labor and cost, and further limits the number of molds. There were problems such as a decrease in productivity.
[0005]
Further, in order to solve the above problem, a female member (female connector) having a circumferential rib formed on a lumen surface has been proposed instead of a female member (female connector) having a smooth tapered lumen. I have. However, the female member (female connector) in which the circumferential rib is formed on the inner surface of the cavity is not stable in dimensions due to the mold mechanism, and is fitted with the conventionally known bamboo-shaped male member (connector). In this case, each projection acts negatively, which may cause a leak.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a fitting structure that solves the above problems, particularly a fitting structure between a male member (male connector) and a female member (female connector). A mating structure that can maintain the mating force even when lowered by
(2) The variation in dimensions of the molded product used in the fitting structure is reduced, a stable fitting is obtained, and the shape of the outer surface of the male member (male connector) affects the fitting property. A female member (female connector) that can form a stable fitting structure with a male member (male connector) having various outer surface portions and a male member (male connector) having a bamboo-shaped or smooth tapered outer surface portion, for example. connector),
Is to provide.
[0007]
[Means for Solving the Problems]
The first aspect of the present invention is a fitting structure of a male member (male connector) and a female member (female connector), wherein the female member (female connector) is a hollow columnar member, and A fitting structure for a male member (male connector) and a female member (female connector), characterized in that the diameter of the lumen of the cylindrical member is reduced stepwise toward the distal end. By doing so, the above problem could be solved.
The male member (male connector) may be formed with an opening at the tip end side and an inner cavity formed in the entire columnar projecting member, and may have a hollow shape so that liquid or gas can flow.
[0008]
The second aspect of the present invention relates to the first fitting structure, wherein a gap between adjacent step-shaped steps of the female member (female connector) has a smooth tapered shape.
[0009]
A third aspect of the present invention is a hollow member that is a cylindrical body or a conduit whose diameter decreases stepwise as the shape of the lumen becomes closer to the distal end side, and a male member (male connector) is provided in the lumen. The present invention relates to a female member (female connector) capable of forming a fitted structure in which the fitting is performed.
[0010]
A fourth aspect of the present invention relates to the female member (female connector), wherein a smooth taper shape is formed between adjacent step-shaped steps in the female member (female connector).
[0011]
The female member (female connector) employed in the present invention has a smaller variation in the dimensions of the molded product itself as compared with a conventionally known female member (female connector) having a circumferential rib formed on the inner surface of a cavity. A stable fitting is obtained, and the shape of the outer surface of the male member (male connector) has little influence on the fitting property. For example, the conventionally known outer surface portion has a bamboo-shaped or tapered male member (male). Connector) can achieve a stable fitting structure.
[0012]
Further, the female member (female connector) employed in the fitting structure of the present invention has a diameter which becomes smaller as the outer surface portion proposed in the application (Japanese Patent Application No. 2002-65367) previously submitted by the present applicant becomes closer to the distal end. It is also possible to achieve a stable fitting structure with a male member (male connector) having a step formed from a plurality of columnar portions whose size is reduced.
[0013]
In the case of fitting a conventionally known male member (male connector) and a female member (female connector), particularly in the case of fitting a male member (male connector) and a female member (female connector) having a smooth tapered surface, a joining surface As a whole, a friction reducing layer is formed by the lubricity promoter. For example, when the lubricity promoting agent is oily, a friction reducing layer due to an oil film is formed on the entire joint surface, and the male member (male connector) and the female member (female connector) are easily removed. On the other hand, in the fitting structure of the present invention as described above, the stepped step formed in the inner cavity of the female member (female connector) is similar to the circumferential rib provided in the conventionally known inner cavity. In a fitting structure with a male member (male connector) having a smooth function and having a smooth tapered surface, it is possible to divide the spread of the friction reducing layer generated in the case of the fitting structure. As a result, when a conventionally known tapered male member (male connector) is fitted to the female member (female connector), the problem occurs when a slip promoting agent adheres to a joint portion. A remarkable decrease in the fitting force is suppressed, and a stable joining force can be maintained.
[0014]
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, the present invention will be described more specifically based on embodiments.
Embodiment 1
The female member (female connector) of the present embodiment has a cylindrical shape having stepped portions a, b, c, d such that the diameter decreases stepwise as the shape of the lumen becomes closer to the distal end side as shown in FIG. A hollow female member (female connector) 4 which is a body or a conduit.
The female member (female connector) of the present embodiment has a shape in which the diameter decreases stepwise toward the distal end side, so that there is no undercut portion, so that deformation during molding hardly occurs. As a result, the molding size is stabilized and the variation in the molded product size is reduced, so that a stable fitting structure with the male member (male connector) can be obtained.
[0015]
Embodiment 2
As shown in FIG. 4, the female member (female connector) of this embodiment has a smooth taper between the adjacent steps of the step-like portions a, b, c, and d in the female member (connector) 4 of the first embodiment. A female member (connector) 5 having a shape portion f. The female member (female connector) 5 has the same effect as the tapered surface of the female member (female connector) having a smoothly tapered portion f between the steps. When the female member (female connector) of the present embodiment is fitted with a known bamboo-shaped male member (connector) shown in FIG. 2, the a, b, c, and d portions of the female member and the bamboo-shaped protrusion The parts can be securely fitted to each other, and stable fitting can be obtained. In addition, since the step-like shape eliminates the undercut portion as in the first embodiment, deformation during molding is less likely to occur, the molding dimensions are stabilized, and the variation in the molded product dimensions is reduced, and the shape is stable. A fitting structure is obtained.
[0016]
The fitting structure 7 of this embodiment shown in FIG. 5 includes a male member (male) having a tapered outer surface shown in FIG. 1 inside the female member (female connector) 4 of the first embodiment shown in FIG. FIG. 3 is a diagram showing a fitting structure when a connector (1) is inserted.
In the fitting structure according to the present embodiment, the stair steps a, b, c, and d formed in the inner cavity of the female member (female connector) according to the first embodiment are formed by the
[0017]
Embodiment 4

The
[0018]
Further, the male member (male connector) preferably has a taper angle of 12.5 ± 3.0 / 100, which is assumed when connecting the tip side edges of adjacent reduced diameter cylinders. The step structure having such a taper angle allows easy insertion when inserting into a female member (female connector), and requires a predetermined pulling force when removing, so it can be easily detached due to an unexpected situation. Can be prevented. That is, when the stepped columnar projection of the male member (male connector) is a stepped columnar projection having a small step, when the lubricity promoter is attached to the joint surface of both connectors, the lubricity promoter is joined. Since it easily spreads over the entire surface, it has little effect in preventing the reduction of the frictional force. Conversely, if the step is too large, the joining area itself becomes small and it becomes easy to separate.
Further, the male member (male connector) 8 of the present embodiment is easier to mold than the bamboo shoot-shaped male member (male connector) as shown in FIG. 2, improving the productivity and reducing the manufacturing cost. it can. Although the male member (male connector) 8 of the present embodiment has the passage 1 formed therein, the male member (male connector) 8 does not have the passage 1 and may simply have a connector function.
[0019]
The male member (male connector) 8 is formed integrally with a distal end of a syringe (outer cylinder) 9 of a medical syringe. In the medical syringe on which the male member (male connector) 8 is formed, the male member (male connector) 8 is inserted into the female member (female connector) of the present invention, for example, the female member (female connector) of the first embodiment. Used by fitting. In addition, this fitting structure can exert not only various excellent effects by the female member (female connector) 4 as described in the first embodiment, but also the syringe as described above with the male member (male connector). Since the
[0020]
