the outer wall of the retainer ring is provided with a clamping boss matched with the clamping groove, and the retainer ring is clamped with the clamping groove of the shell through the clamping boss;
the metal spring is arranged in the metal spring mounting groove.
Furthermore, two inner sealing rings are arranged in the sealing cavity and are positioned between the shell and the check ring.
Furthermore, an isolating ring is arranged in the sealing cavity and is positioned between the two inner sealing rings.
Further, the downside symmetry of casing is provided with two guide ways, two guide ways are used for realizing pre-compaction and leading in the retaining ring assembly.
Has the advantages that: the utility model discloses a metal spring formula quick connector has following advantage:
1. the clamping of the matching end is realized by utilizing the elastic deformation of the metal spring, the space requirement can be reduced due to the fine locking spring, and the device is suitable for the increasingly narrow space in the vehicle body;
2. the joint shell and the check ring are assembled and clamped, so that the formation of foreign matters can be reduced, and the cleanliness of a product can be improved;
3. the joint is provided with two inner sealing rings, so that the sealing performance is better.
