Abstract

The invention relates to a quick connector. The quick connector comprises a male connector and a female connector, wherein the male connector and the female connector are provided with convex rings. The male connector can be detachably connected with the female connector in a sealed mode. The female connector comprises a shell, a button, an outer check ring, an outer O-shaped ring, an inner checkring and an inner O-shaped ring. According to the quick connector, the shape of the shell is simplified, and although the cost of a button die is increased, the comprehensive cost is reduced as the number of types of shells is large and the number of types of button dies is small. In addition, the number of parts needing to be installed on the quick connector is small, the direction of the buttoncan be adjusted, a core die of the shell is of a cylindrical structure with steps, no hole or groove needs to be formed, the cost is low, and the service life is long.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a quick connector. Background technique [0002] Quick connectors are currently widely used in automotive applications. The quick connector in the standard "Specification for Quick Connectors of Fuel and Vapor / Volatilization System SAE J20442009" refers to a quick connector suitable for connection of fuel supply, return, and vapor / volatile systems. [0003] See figure 1 , 2 , the female connector in the quick connector, also known as the female connector. Among them, the female connector of A. Raymond Company is the mainstream product, such as the Chinese invention patent with publication number CN104110546A, which discloses a locking part for locking pipe connections. In order to place the button 1, the shell 3 needs to be provided with a roughly rectangular button section 31 , the inner wall structure of the button section 31 is very complicated, and the button section 31 needs to...
