AI Technical Summary
Technical Problem
Existing connectors have problems with unstable sealing, difficult operation and complex manufacturing when using certain materials and vacuum/negative pressure conditions.
Method used
The threadless lock connector design is adopted, and the seal is maintained under vacuum/negative pressure conditions through the O-ring and the joint structure, and the stable connection between the male threadless connector and the female threadless connector is achieved through the mating of the lock ring and the joint structure.
Benefits of technology
Improves the ease of use and sealing robustness of the connector, reduces the operator's clinical steps, and simplifies manufacturing technology.

Abstract
A large aperture threadless lock catch connector provided by a connector apparatus, comprising: a male threadless connector comprising: a first through-hole of a specific aperture; an o-ring having a first outer diameter disposed on a first outer surface on a second end of the first through hole; and an engagement structure disposed on the first outer surface, the engagement structure having a generally circular periphery having a second outer diameter; a female threadless connector comprising: an inner surface having a first inner diameter substantially equal to the first outer diameter; and a catch ring projecting inwardly from the inner surface, a second inner diameter of the catch ring being smaller than the second outer diameter, where the catch ring and the engagement structure selectively secure the male threadless connector within the female threadless connector thereby forming a liquid-tight seal between the inner surface and the o-ring.
