Provided with opening, wherein elastic top is mounted in the rear end of fixed spool seal section 222 forward due to seal ring protective sleeve, the during use
Before two stopping surfaces 244 and the block mating band dynamic seal ring protective case of the first stopping surface 251 are synchronously moved rearwards, sealing ring protection
The front opening of set fluid passage is adjacent on the rear end face of fixed spool seal section 222 all the time, is limited to this, public access head capsule
Fluid passage in internal fluid passage and parent shell can not realize conducting, and in the second stopping surface and the first stopping surface block
Coordinate, drive Moveable seal cartridge to be moved rearwards relative to female joint housing with the insertion of public access casing, movable sealing is put
The second stopping surface drive the first stopping surface be moved rearwards relative to female joint housing, now seal ring protective sleeve connects relative to mother
Casing is moved rearwards, and the rear end face for being opened on fixed spool seal section of seal ring protective sleeve front end separates, female joint shell
Internal fluid passage turns on the fluid passage in public access casing, it is seen then that pin end and female joint in the present embodiment
Fluid passage can not mutual conduction before the first stopping surface contacts with the second stopping surface.In other implementations of the present invention
In example, the pin end housing seal section of pin end can lengthen, now when the first stopping surface is in contact with the second stopping surface, Gu
Fixed valve plug seal section is slidably matched with pin end housing seal section, in the fluid passage in female joint housing and public access casing
Fluid passage does not turn on, and now needs Moveable seal cartridge to drive seal ring protective sleeve to be moved rearwards relative to female joint housing, directly
Continue to be moved rearwards relative to female joint housing to pin end housing seal section and depart from fixed spool seal section, realize male and female
The connection of the fluid passage of joint, the distance that first and second stopping surface is in raw bits in Moveable seal cartridge are also less than second
Stopping surface present position and when Moveable seal cartridge is between present position when Moveable seal cartridge is in raw bits
Distance.Distance of second stopping surface when public access casing abuts with Moveable seal cartridge between pin end sealing ring is less than the
One stopping surface to seal ring protective sleeve front end face distance, it is ensured that when first and second stopping surface is engaged sealing ring protect
The outer peripheral face of sheath has enough length, ensures that there is seal ring protective sleeve enough length its outer peripheral face is sealed with pin end
