Floating blind-mate connector with sealing ring protection function
Technical Field
The invention relates to a floating blind-mate connector with a sealing ring protection function.
Background
The quick connector is a device for realizing quick disconnection or connection of pipelines, is mostly used in fluid pipelines, is convenient for arrangement and connection of various elements for realizing different fluid loops, and is mostly provided with a blind plug connector for improving the installed density, and the installed capacity of the liquid cooling is continuously improved. The traditional blind-mate quick connector has no sealing ring protection function, and fluid is in contact with the sealing ring for a long time, so that the sealing ring is accelerated to age, lose elasticity and lose the sealing function; if impurities and particles exist in the fluid, the impurities and the particles in the fluid continuously impact and rub the sealing ring along with the rapid flow of the fluid, so that the sealing ring is forced to be cracked and damaged, and finally the sealing function is lost. And, when the fluid velocity of flow is too big, the fluid can be washed the sealing washer away from the mounting groove, causes piping system to leak.
