Abstract

A quick connect/disconnect coupling for dental handpieces that includes a pair of telescoping coupling sleeves equipped with a plurality of bayonet slots and lugs for detachably connecting the sleeves together.
In one sleeve is a spring-loaded connector body having a plurality of axially extending passages communicating with the fluid (air and water) conduits of a supply hose, the connector having a hard-surface planar end face exposed at the distal end of the sleeve. The other sleeve is a proximal extension of a handpiece and contains a plurality of tubes arranged and dimensioned to be received in the passages of the connector body when the two sleeves are coupled together. A resilient gasket, confined by a rigid support ring, surrounds the tubes and includes frusto-conical ring portions about such tubes for sealingly engaging the end face of the connector body.
When the sleeves axe coupled together, the spring-loaded connector body is axially displaced so that the force of the spring maintains the body and gasket in sealing contact under a predetermined and reproducible compressive load.
