Abstract
The connector assembly includes a housing with an open bore which extends along an axis from an open first end to an open second end. The housing further includes a plurality of fingers that are spaced circumferentially from one another and are deflectable in a radial direction. At least one of the fingers has a plurality of teeth that are spaced axially from one another and extend into the open bore of the housing for biting into the first tube to resist pull out of the first tube from the open bore. Each of the teeth also extends by a height to a leading edge of an engagement surface which also includes an angled portion that extends at an angle relative to the axis. The axially spaced teeth have at least one of differing heights and differing angles of the angled portions.
Claims16
A connector assembly for connecting and establishing fluid communication between a first tube and a second tube, comprising:
- a housing made as a single monolithic piece with an open bore which extends along an axis from an open first end to an open second end;
- at least one sealing element disposed in said open bore for establishing a fluid tight seal between said housing and one of the first and second tubes;
- said monolithic housing including a plurality of fingers that are spaced circumferentially from one another and are deflectable in a radial direction;
- a plurality of rows wherein each row contains a plurality of teeth interconnected with one another through a spine which is at least partially embedded within at least one of said fingers, each row of teeth being spaced axially from one another, an end of each tooth being transversely offset from said spine, and each tooth extending into said open bore of said housing for engaging into the first tube to resist pull out of the first tube from said open bore;
- each of said teeth having a triangular portion which projects into said open bore, said triangular portion having a front surface which extends perpendicularly to said axis and a back surface which is angled relative to said axis by less than ninety degrees;
- wherein at least one of said front surfaces of said axially spaced teeth have differing heights and said back surfaces of said axially spaced teeth extend at differing angles relative to said axis;
- and
- wherein said teeth are made of metal for biting into the first tube or second tube.
