Description

本考案は、コネクタに関し、特に、可撓性のあるパイプの嵌合コネクタに関する。詳しくは、締付リングに二つの錐面が形成され、軸方向上において溝部が形成され、コネクタ本体と締付ナットに錐面が別々に形成される可撓性のあるパイプの嵌合コネクタに関するものである。 The present invention relates to a connector, and more particularly to a flexible pipe fitting connector. More specifically, the present invention relates to a flexible pipe fitting connector in which two conical surfaces are formed in a tightening ring, a groove is formed in the axial direction, and conical surfaces are separately formed in a connector main body and a tightening nut. Is.

図１および図２に示すように、可撓性のあるパイプ１０の端部に係合される従来の係合コネクタの構造において、コネクタ本体２１は係合側に締め付け部位２１１および係合部位２１２を有し、コネクタ本体２１の係合部位２１２は可撓性のあるパイプ１０に嵌め込まれる。挿入・抜出リング２２は可撓性のあるパイプ１０の端部の外周に装着され、かつ挿入・抜出リング２２の外周に内錐面２２１を有する。締め付け部位２３１によってコネクタ本体２１の締め付け部位２１１と噛み合う挿入・抜出ナット２３は、挿入・抜出リング２２の内錐面２２１に対応して形成された外錐面２３２を有するため、締め付けおよび推力を介して生じる挿入・抜出関係によって挿入・抜出リング２２は可撓性のあるパイプ１０の端部とコネクタ２１の係合部位２１２とを連結させることが可能である。しかし、このような構造による係合コネクタは、係合強度があまり良好でないだけでなく、耐圧試験が３９４Ｋｇｆ／ｃｍ²に達する際に漏洩現象が発生し、抗張力試験が５０Ｋｇに達する際に逸脱現象が発生する。 As shown in FIGS. 1 and 2, in the structure of a conventional engagement connector that is engaged with the end portion of the flexible pipe 10, the connector body 21 has a tightening portion 211 and an engagement portion 212 on the engagement side. The engaging portion 212 of the connector main body 21 is fitted into the flexible pipe 10. The insertion / extraction ring 22 is attached to the outer periphery of the end of the flexible pipe 10 and has an inner cone surface 221 on the outer periphery of the insertion / extraction ring 22. The insertion / extraction nut 23 that meshes with the tightening portion 211 of the connector main body 21 by the tightening portion 231 has an outer cone surface 232 formed corresponding to the inner cone surface 221 of the insertion / extraction ring 22. The insertion / extraction ring 22 can connect the end portion of the flexible pipe 10 and the engagement portion 212 of the connector 21 by the insertion / extraction relationship generated through the connection. However, the engagement connector having such a structure not only has not very good engagement strength, but also a leakage phenomenon occurs when the pressure resistance test reaches 394 kgf / cm ² , and a departure phenomenon when the tensile strength test reaches 50 kg. Occurs.

以下、本考案の一実施形態を図面に基づいて説明する。
（一実施形態）
図３および図４に示すように、本形態は、コネクタ本体３０、締付リング４０および締付ナット５０を備える。
コネクタ本体３０は、係合側に締め付け部位３１および係合部位３２を有し、締め付け部位３１は係合部位３２を奥へ入り込ませるため、環状の陥没部３１１を有し、環状の陥没部３１１の外環は奥へ漸縮していく第一外錐面３２１を呈し、可撓性のあるパイプ６０の端部と係合部位３２とを連結させる。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(One embodiment)
As shown in FIGS. 3 and 4, this embodiment includes a connector main body 30, a tightening ring 40, and a tightening nut 50.
The connector main body 30 has a fastening part 31 and an engaging part 32 on the engagement side, and the fastening part 31 has an annular depression 311 so as to allow the engagement part 32 to enter deeper, and the annular depression 311. The outer ring has a first outer conical surface 321 that gradually shrinks to the back, and connects the end of the flexible pipe 60 and the engaging portion 32.

締付リング４０は、可撓性のあるパイプ６０の端部の外周に嵌るため、外周縁部の内側にコネクタ本体３０の第一外錐面３１２に対応する第一内錐面４１を有し、外周縁部の外側に第二内錐面４２を有し、軸方向上において削って形成された溝部４３を有する。 The fastening ring 40 has a first inner cone surface 41 corresponding to the first outer cone surface 312 of the connector body 30 inside the outer peripheral edge portion in order to fit on the outer periphery of the end portion of the flexible pipe 60. The outer peripheral edge portion has a second inner conical surface 42 and a groove portion 43 formed by cutting in the axial direction.

締付ナット５０は、コネクタ本体３０の締め付け部位３１に対応する締め付け部位５１と、締付リング４０の第二内錐面４２に対応する第二外錐面５２とを有し、かつ外端が開き可能な口部５３を有する。 The tightening nut 50 has a tightening portion 51 corresponding to the tightening portion 31 of the connector body 30 and a second outer conical surface 52 corresponding to the second inner conical surface 42 of the tightening ring 40, and the outer end thereof is It has an opening 53 that can be opened.

また、可撓性のあるパイプ６０の構造は、フッ素樹脂から構成される芯管６１と、芯管６１の外周を覆う金属ネット層６２とを有する。可撓性のあるパイプ６０はブレーキ油管などの油圧管に応用されている。 The flexible pipe 60 has a core tube 61 made of a fluororesin and a metal net layer 62 that covers the outer periphery of the core tube 61. The flexible pipe 60 is applied to a hydraulic pipe such as a brake oil pipe.

上述した構造により、締付ナット５０でコネクタ本体３０を締め付ける場合、締付リング４０の第一内錐面４１および第二内錐面４２は、コネクタ本体３０の第一外錐面３１２および締付ナット５０の第二外錐面５２に対応する。このとき締付リング４０の溝部４３は、締め付けおよび推力を介して生じる挿入・抜出力によって締付作用を果たすため、締付リング４０は可撓性のあるパイプ６０の端部とコネクタ本体３０の係合部位３２とを緊密に連結させることが可能である。耐圧試験が８００Ｋｇｆ／ｃｍ²に達するとしても、漏洩現象が発生しない。抗張力試験が１５５Ｋｇに達する際、逸脱現象が発生する。従って、本考案は係合強度を高める効果を有する。 With the above-described structure, when the connector body 30 is tightened with the tightening nut 50, the first inner cone surface 41 and the second inner cone surface 42 of the tightening ring 40 are tightened with the first outer cone surface 312 of the connector body 30 and the tightening. It corresponds to the second outer cone surface 52 of the nut 50. At this time, since the groove portion 43 of the tightening ring 40 performs a tightening action by insertion / extraction output generated through tightening and thrust, the tightening ring 40 is connected to the end of the flexible pipe 60 and the connector body 30. It is possible to connect the engagement part 32 closely. Even if the pressure test reaches 800 kgf / cm ² , no leakage phenomenon occurs. When the tensile test reaches 155 kg, a departure phenomenon occurs. Therefore, the present invention has an effect of increasing the engagement strength.
