Fluid connection assembly

A fluid connection assembly, comprising:

• a fluid connection adapter having first and second adapter ends, the fluid connection adapter providing a tapered lock engagement surface and at least a first seal section;
• a fluid connection housing assembly having first and second housing ends, the fluid connection housing assembly providing a displaceable locking ring, a plurality of locking elements, and at least a first seal bore;
• wherein each locking element is disposed to constrict radially via rotation about a corresponding pivot pin,
• wherein each locking element has a locking element outer surface and a tapered locking element inner surface;
• wherein, during entry of the second adapter end into the first housing end:
• (A) the locking elements are disposed to rotate such that the locking element inner surfaces oppose the lock engagement surface;
• and (B) the first seal section sealingly contacts the first seal bore;
• such that when the locking ring is displaced, progressive engagement of a locking ring inner surface on the locking element outer surfaces maintains opposing tapers between the locking element inner surfaces and the lock engagement surface;
• and
• wherein the first seal section is disposed to expand radially responsive to introduction of internal pressure within the second adapter end, such that when the first seal section expands radially, the first seal section further tightens sealing contact against the first seal bore;
• and
• wherein progressive engagement of the locking ring inner surface on the locking element outer surfaces further urges the locking element inner surfaces to tighten against the lock engagement surface.

A fluid connection assembly, comprising:

• a fluid connection adapter having first and second adapter ends, the fluid connection adapter providing a tapered lock engagement surface and at least a first seal section;
• the fluid connection adapter further providing a rib;
• a fluid connection housing assembly having first and second housing ends, the fluid connection housing assembly providing a displaceable locking ring, a plurality of locking elements, at least a first seal bore, and a housing notch;
• wherein each locking element is disposed to constrict radially via rotation about a corresponding pivot pin;
• wherein each locking element has a locking element outer surface and a tapered locking element inner surface;
• wherein, during entry of the second adapter end into the first housing end until the rib abuts the housing notch:
• (A) the locking elements are disposed to rotate such that the locking element inner surfaces oppose the lock engagement surface;
• and (B) the first seal section sealingly contacts the first seal bore;
• such that when the locking ring is displaced, progressive engagement of a locking ring inner surface on the locking element outer surfaces maintains opposing tapers between the locking element inner surfaces and the lock engagement surface;
• and
• wherein the first seal section is disposed to expand radially responsive to introduction of internal pressure within the second adapter end, such that when the first seal section expands radially, the first seal section further tightens sealing contact against the first seal bore;
• wherein progressive engagement of the locking ring inner surface on the locking element outer surfaces further urges the locking element inner surfaces to tighten against the lock engagement surface.
