Abstract
A swivelable quick connect assembly for use with tubular conduits is disclosed as comprising a housing having an axial bore for receiving one end of the conduit, an elastomeric ring-like seal is disposed in the bore for providing a fluidtight seal between confronting portions of the conduit and the housing, an annular bushing is disposed in the bore for positioning the seal and for guiding the one end of the conduit into nesting relationship with the bore, and a retainer is detachably secured to the housing and is cooperable with an annular projection on the conduit for securing the conduit in its operative position within the bore, the retainer having resilient deformable portions which are adapted to snap over the locking wall upon insertion of the conduit into the housing bore.
Claims21
A connector assembly for providing a swivelable quick connection, comprising:
- a tubular conduit adapted to convey fluid, having outwardly projecting annular surface means, formed at a predetermined distance from an end of said conduit to be connected, for providing a blocking wall portion disposed transversely to a central axis of said conduit;
- a housing having axial bore means formed therein for receiving said conduit at a first end for providing a fluid path at a second end, said housing having an inwardly extending flange disposed at said first end thereof;
- elastomeric ring means disposed in said bore means for providing a seal between said conduit and said housing;
- annular bushing means disposing in said bore means of said housing for positioning said ring means and for guiding the insertion of said conduit into a sealing engagement with said ring means;
- and
- retainer means, demountably coupled to said first end of said housing, for cooperating with said blocking wall portion of said annular surface means to resist the disconnection of said conduit from said housing;
- said retainer means being made from a resilient material, and comprised of a circumferentially continuous ring having an outer diameter approximately corresponding to the diameter of said inwardly extending flange of said housing, jaw means projecting from a first side of said ring, and converging at one end and extending beyond said outer diameter of said ring at another end, for providing said cooperation with said annular surface means of said conduit, and tab means projecting radially outwardly from a second side of said ring for positioning said retainer means at said first end of said housing in cooperation with said jaw means.
In a connector assembly for providing a swivelable quick connection, having a tubular conduit adapted to convey fluid and formed with an annular projection disposed a predetermined distance from the end of said conduit to be connected, the improvement comprising:
- a housing formed with an axial bore for receiving said conduit at a first end and for providing a fluid path at a second end, said housing including an inwardly extending flange at said first end;
- sealing means disposed within said axial bore for providing a seal between said conduit and said housing;
- an annular bushing disposed in said bore means adjacent to said sealing means;
- and
- a retainer made from a resilient material and comprised of a circumferentially continuous ring, a plurality of jaw members projecting from a first side of said ring, and a plurality of tab members projecting radially outwardly from a second side of said ring;
- said flange of said housing being interposed between said tab members and said jaw members of said retainer, and said tab members and said jaw members cooperating to detachably secure said retainer to said housing at said first end;
- said jaw members of said retainer being formed to extend beyond the outer diameter of said ring at one end and to converge at the other end toward the outer diameter of said conduit such that said jaw members cooperate with said annular projection on said conduit to resist the disconnection of said conduit from its operative position within said axial bore of said housing.
