Problems solved by technology

However, the female joint is a metal part, and the sealing cannot be realized through the surface-to-surface cooperation between the metal and the metal. Therefore, the end face gasket loses the significance of forming a seal for the sealing through hole
[0014] Thirdly, after the sealing shaft is installed in the above structure, the sealing through hole matched with the sealing shaft is a stepped hole. Therefore, this structure not only needs to increase the production cost of the sealing shaft, but also complicates the structure of the sealing through hole , so that the cost of the product increases

Abstract

The invention relates to a connector of an automotive air conditioning pipeline. A first through hole for penetrating through a first body is formed in the first body, one end of a first annular puncturing part is fixed to the first body, and the first annular puncturing part surrounds the periphery of a hole opening of the first through hole; a second through hole for penetrating through a secondbody is formed in the second body, one end of a second annular puncturing part is fixed to the second body, and the second annular puncturing part surrounds the periphery of a hole opening of the second through hole; and a metal sealing part is located between the first annular puncturing part and the second annular puncturing part, applies pressure to the first body and / or the second body, so that the first annular puncturing part punctures into one end of the metal sealing part to form a first sealing part between the first body and the metal sealing part, and the second annular puncturingpart punctures into the other end of the metal sealing part to form a second sealing part between the second body and the metal sealing part. The connector of the automotive air conditioning pipelinehas the advantages of simple structure and high reliability.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning pipe fittings, in particular to a connector for automobile air-conditioning pipelines. Background technique [0002] Automobile air-conditioning pipelines include connectors and pipelines connected to both ends of the connectors. The assembly between the connectors and the pipelines needs to be sealed. For example, CN209278668U discloses a sealing structure for R744 air-conditioning pipelines. The sealing structure includes male joints, end faces The sealing gasket, the first O-ring, the second O-ring and the female joint, the inner end surface of the male joint is provided with a hollow structure sealing shaft, and the sealing shaft is connected with the connection hole for installing the air-conditioning pipe on the outer end surface of the male joint The seal shaft is installed with the end face gasket, the first O-ring and the second O-ring sequentially in the axial directi...
