Plug connector and fluid connector assembly using the plug connector

Abstract

The invention provides a plug connector and a fluid connector assembly with the plug connector. The fluid connector assembly comprises the plug connector and a socket connector, the plug connector comprises a plug shell, a plug valve element is assembled in the plug shell in a front-and-back guide movement manner, a plug spring is arranged at the back end of the plug valve element, and a spring base is arranged at the back end of the plug shell; the plug valve element is further provided with a guide sleeve extending front and back, and the guide sleeve is provided with a guide inner circumferential face in guide fit with the outer circumferential face of the plug spring; and the spring base comprises a guide column which extends front and back and is used for being in guide slide fit with the back end of the plug spring. In the insertion process, when the plug valve element moves backwards, the plug spring cannot generate twisting deformation deviating from the axis in the compression process, it is guaranteed that the plug spring can normally reset when the plug connector is pulled down from the socket connector, stable axial elasticity is provided for the plug valve element, and the good sealing effect of the plug valve element is guaranteed.

Description

technical field [0001] The invention relates to a plug connector and a fluid connector assembly using the plug connector. Background technique [0002] In hydraulic systems and liquid transmission systems, fluid connectors are generally used to realize the connection and disconnection between pipelines, pipelines and hydraulic systems, and to ensure the sealing of pipelines and hydraulic systems during the connection and disconnection process. . [0003] Existing fluid connectors such as the fluid connector disclosed in the Chinese invention patent with the application publication number of CN104500887A and the application publication date of April 8, 2015, the fluid connector can be a plug connector or a socket connector, a plug connector It includes a connector housing, which has a fluid channel extending along the front and rear directions. The connector housing includes a cylindrical body, and the cylindrical body is guided to move and equipped with a plug valve core at...

Problems solved by technology

[0004] The rear end of the plug spool spring of this fluid connector is pressed against the spring seat, and the front end is pressed against the rear end of the plug spool. Due to the longer length of the spool spring, when the plug spool is pushed against the socket spool When moving downward and backward, the spring of the spool is easy to deviate from the axis and twist and deform. When the plug spool is not subjected to the push force, it cannot be reset normally, and a good seal cannot be guaranteed, which seriously affects the use effect of the connector.
