FLUID CONNECTOR WITH ANNULAR GROOVE AND SEAL

摘要

In accordance with an example embodiment, a fluid connector may include an inner face, outer face, annular groove extending below the inner face and the outer face, and annular seal installed in the groove. The groove may include an inner wall, bottom wall, outer wall, and lip. The annular seal, in an undeformed state, may include a first convex surface, a second concave surface, a third convex surface, and a fourth concave surface. The second surface may be positioned radially inward of the first surface and radially outward of the third surface. The third surface may be between the second surface and a fourth surface, radially inward of the first surface. The fourth surface may be positioned radially outward of the third surface and radially inward of the first surface.

主权项

1. A fluid connector comprising:
an inner face; an outer face; an annular groove positioned radially outward of the inner face and radially inward of the outer face, the groove extending below the inner face and the outer face, the groove comprising:
an inner wall between the inner face and a bottom wall;the bottom wall between the inner wall and an outer wall;the outer wall between the bottom wall and a lip, the outer wall substantially parallel to the inner wall; andthe lip between the outer wall and the outer face, the lip protruding radially inward beyond at least a portion of the outer wall; and an annular elastomeric seal installed in the groove, the seal, in an undeformed state, comprising:
a first surface which is convex;a second surface which is concave, the second surface between the first surface and a third surface, the second surface positioned radially inward of the first surface and radially outward of the third surface;the third surface which is convex, the third surface between the second surface and a fourth surface, the third surface positioned radially inward of the first surface; andthe fourth surface which is concave, the fourth surface between the third surface and the first surface, the fourth surface positioned radially outward of the third surface and radially inward of the first surface.
