또한, 상기 흡입머플러(300)의 흡입부(310) 외주면에 면밀착되는 연결관(420)의 단부에는 면밀착력을 향상시키기 위한 평탄면(422)이 형성되며, 상기 평탄면(422)을 통해 작동유체의 누설을 현저하게 방지할 수 있다.In addition, a flat surface 422 is formed at an end of the connection pipe 420 which is in close contact with the outer circumferential surface of the suction part 310 of the suction muffler 300, and through the flat surface 422 The leakage of the working fluid can be prevented remarkably.

따라서, 상기와 같은 구성을 가지는 연결관(420)을 통해 흡입파이프(200)와 흡입머플러(300)를 보다 안정되게 연결시킬 수 있으며, 더불어 작동유체의 누설을 현저하게 방지할 수 있다.Therefore, the suction pipe 200 and the suction muffler 300 can be more stably connected through the connection pipe 420 having the above configuration, and the leakage of the working fluid can be significantly prevented.

이하, 본 발명의 다른 실시예를 설명함에 있어 전술한 실시예와 동일한 구성 및 기능을 가지는 구성부호에 대해서는 동일한 구성부호를 사용하며, 중복되는 설명은 생략한다.Hereinafter, in describing other embodiments of the present invention, the same reference numerals are used for components having the same configuration and function as the above-described embodiments, and redundant descriptions thereof will be omitted.

본 실시예의 밀폐형 압축기의 흡입구조는 도 4에 도시된 바와 같이, 전술한 고정편(410)의 선단에 결합된 연결관(420)을 더욱 견고하게 고정하기 위해 고정클 립(500)을 결합시킨 것이다.In the suction structure of the hermetic compressor of the present embodiment, as shown in FIG. 4, the fixing clip 500 is coupled to fix the connection pipe 420 coupled to the front end of the fixing piece 410 more firmly. will be.

즉, 상기 고정클립(500)은 "C"자 형상으로 탄성복원력을 가지는 것으로, 상기 고정편(410)의 선단에 연결관(420)을 끼워서 결합시킨 다음, 연결관(420)의 외주를 감싸는 위치에서 고정클립(500)을 인장시킨 후, 상기 고정클립(500)을 인장시키는 외력을 제거하면 고정클립(500)의 탄성복원력에 의해 연결관(420)을 가압함으로써 연결관(420)을 보다 견고하게 고정할 수 있다.That is, the fixing clip 500 is to have an elastic restoring force in the shape of "C", to couple the connecting pipe 420 to the front end of the fixing piece 410, then wrap the outer periphery of the connecting pipe 420 After tensioning the fixing clip 500 in position, removing the external force to tension the fixing clip 500 to press the connecting pipe 420 by the elastic restoring force of the fixing clip 500 to see the connecting pipe 420 I can fix it firmly.

상기와 같이 고정편과 연결관으로 이루어지는 연결부를 통해 흡입파이프와 흡입머플러를 연결하는 밀폐형 압축기를 제작함으로써 작동유체의 누설을 현저하게 방지할 수 있을 뿐만 아니라, 고무재질의 연결관이 압축기 케이스에 부착됨으로써 방진역할을 수행하여 압축기의 진동 및 소음을 크게 감소시킬 수 있는 효과가 있다.As described above, by manufacturing a hermetic compressor connecting the suction pipe and the suction muffler through the connection part consisting of the fixing piece and the connecting pipe, it is possible not only to significantly prevent the leakage of the working fluid, but also to attach the rubber connection pipe to the compressor case. As a result, the vibration and noise performance of the compressor can be greatly reduced.
