本発明は、外周部に環状の山条を一定の間隔で多数設け
た波形管を接続するための波形管接続具に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a corrugated pipe connector for connecting corrugated pipes having a large number of annular ridges arranged at regular intervals on the outer periphery.
［従来の技術］
建築物の屋内配線、輸送機器内の配線などに使用される
可撓性の配線保護用導管として、外周部に環状の山条を
一定の間隔で多数設けた波形管が使用されている。[Prior art] A corrugated tube with a large number of annular ridges arranged at regular intervals on the outer periphery is used as a flexible wiring protection conduit used for indoor wiring in buildings, wiring inside transportation equipment, etc. has been done.
この種の波形管を相互に接続し、或いは伯の部材と接続
するために、従来、特公昭６０−２８２１５号公報に示
されるようなソケット筒状の接続管が提案されている。In order to connect these types of corrugated tubes to each other or to a hollow member, a cylindrical socket-shaped connecting tube as shown in Japanese Patent Publication No. 60-28215 has been proposed.
この接続管は、波形管の端部に外嵌可能なソケット筒の
外周壁に窓が設けられ、この窓からＣ形の止め部材をソ
ケット筒内に差し込み、止め部材の両側先端部を波形管
の谷部に圧入嵌合してソケット筒を波形管の端部に固定
する構造である。In this connection pipe, a window is provided on the outer circumferential wall of a socket tube that can be fitted externally to the end of the corrugated tube, and a C-shaped stopper member is inserted into the socket tube through the window, and the ends of both sides of the stopper are attached to the corrugated tube. The socket tube is press-fitted into the trough of the corrugated tube to fix it to the end of the corrugated tube.
［発明が解決しようとする問題点］
しかしながら、この従来の接続具は、Ｃ形の止め部材が
ソケット筒と完全に別体として形成され、接続具が波形

続具を装着或いは着は苔える際、小形の止め部材が紛失
しやすい問題があった。[Problems to be Solved by the Invention] However, in this conventional connector, the C-shaped stopper member is formed completely separate from the socket tube, and until the connector is inserted into the end of the corrugated pipe, Since it is a separate part, there is a problem in that the small stopper member is easily lost when the connecting tool is attached or disassembled.
さらに、止め部材を嵌入するためにソケット筒に設けら
れた窓が、ソケット筒の外周壁のほぼ半周を連続開口し
て形成されているため、ソケット筒の強度が著しく低下
し、ソケット筒が破損したり、外力によって波形管から
外れることがあった。Furthermore, since the window provided in the socket tube for fitting the stopper member is formed by continuously opening approximately half of the outer peripheral wall of the socket tube, the strength of the socket tube is significantly reduced and the socket tube is damaged. or it could come off from the corrugated tube due to external force.
本発明は上記の問題点を解決するものであって、波形管

破損したり、外力によって波形管から容易に外れること
のない波形管接続具を提供することを目的とする。The present invention solves the above problems by integrally forming a cylindrical body that is fitted onto the end of the corrugated tube and a fitting fixing section that is fitted onto the outer circumference of the corrugated tube. The structure is such that it cannot be easily separated, which prevents the fitting and fixing part from being lost, and also ensures sufficient strength of the outer peripheral wall of the cylindrical body, which prevents the cylindrical body from being damaged or easily detached from the corrugated tube due to external force. The purpose of this invention is to provide a corrugated pipe connector that will never cause damage.

Therefore, in this embodiment, the release levers 6a, 6b can be easily removed by using a rod-shaped member such as a screwdriver or a member whose tip is caught in the through holes 10a, 10b. In addition, since the release levers 6a and 6b do not need to protrude as in the first embodiment, they may come into contact with other members or accidentally touch the release levers 6a and 6b with fingertips after the corrugated tube 4 is fixed. This prevents the fitting and fixing parts 2a and 2b from being opened by mistake.

FIG. 8 is a cross-sectional view of the corrugated tube connector when it is open, and FIG. 9 is a cross-sectional view of the corrugated tube connector and the corrugated tube when they are fitted. In this embodiment, a protruding piece 1 is provided on the upper part of the lips 7a and 7b.
1a, 11b+ are provided. Therefore, as shown in FIG. 9, when the corrugated tube 4 is fitted, the protruding pieces 11a and 11b are pressed by the engaging pieces 12a and 12b of the main body 1a, making the fitting of the fitting fixing parts 2a and 2b even stronger. This prevents the fitting and fixing portion from opening accidentally.
