Claims
- 1. A quick connector adapted for releasably engaging an elongated male member comprising:
- a first housing portion defining an opening adapted for receiving said male member having a male member outer circumferential surface and a first through passage, said first housing portion including a first anular bearing surface within said first through passage adapted for slip-fit engagement with said male member outer circumferential surface to non-movably, radially support and center said male member in said first housing;
- a second housing portion defining a second through passage, said second housing portion including a second annular bearing surface within said second through passage adapted for slip-fit engagement with said male member outer circumferential surface to non-movably, radially support and center said male member to said second housing;
- said first and second housing portions interconnected at a joint aligning said first and second through passages;
- retainer means, independent of said first bearing surface, adapted to releasably interconnect said first housing portion and said male member;
- sealing means disposed within said second housing portion adapted to effect sealing engagement between said male member outer circumferential surface and an inner circumferential surface of said second through passage; and wherein:
- said first and second bearing surfaces are axially spaced and straddle said sealing means, said sealing means sealing said second through passage from said joint between said first and second housing portions.
- 2. The quick connector of claim 1, wherein said joint is disposed generally axially adjacent said first bearing surface.
- 3. The quick connector of claim 1, wherein said joint extends circumferentially about said housing portions.
- 4. The quick connector of claim 1, wherein said first and second housing portions define radially extending surface contours which cooperate to mechanically couple said housing portions at said joint.
- 5. The quick connector of claim 4, wherein one of said housing portions is formed of thermoplastic material and the other of said housing portions is formal from metal.
- 6. The quick connector of claim 1, wherein said first and second housing portions are constructed of dissimilar materials.
- 7. The quick connector of claim 6, wherein said first housing portion is formed of thermoplastic material and said second housing portions is formed of metal.
- 8. The quick connector of claim 1, wherein said second housing portion includes extension means adapted for fluid tight interconnection with a conduit.
- 9. The quick connector of claim 8, wherein said extension means comprises an axially extending flange.
- 10. The quick connector of claim 9, wherein a cylindrical surface of said flange is mechanically connected to a mating cylindrical surface of said conduit.
- 11. The quick connector of claim 10, wherein said mechanical interconnection is effected by welding.
- 12. The quick connectors of claim 10, wherein said flange is integrally formed with said conduit.
- 13. A quick connector adapted for releasably engaging an elongated male member comprising:
- a first housing portion defining an opening adapted for receiving said male member and a first through passage;
- a second housing portion defining a second through passage;
- said first and second housing portions interconnected at a joint aligning said first and second through passages, said joint including material of said second housing portion plastically deformed radially into a mating recess formed in said first housing portion
- retainer means adapted to releasably interconnect said first housing portion and said male member; and
- means disposed within said second housing portion adapted to effect sealing engagement between an outer circumferential surface of said male member and an inner circumferential surface of said second through passage.
- 14. A quick connector assembly comprising:
- an elongated male member having a male member outer circumferential surface;
- a female member including a first housing portion defining an opening for receiving said male member and a first through passage, said first housing portion including a first annular bearing surface within said first through passage adapted for slip-fit engagement with said male member outer circumferential surface to non-movably, radially support and center said male member in said first housing;
- a second housing portion defining a second through passage, said second housing portion including a second annular bearing surface within said second through passage adapted for slip-fit engagement with said male member outer circumferential surface; to non-movably, radially support and center said male member to said second housing
- said first and second housing portions interconnected at a joint aligning said first and second through passages;
- retainer means, independent of said first bearing surface, operative to releasably interconnect said first housing portion and said male member; and
- sealing means disposed within said second housing portion to effect sealing engagement between said male member outer circumferential surface and an inner circumferential surface of second through passage, said first and second bearing surfaces axially spaced and straddling said sealing means, with said sealing means sealing said second through passage from said joint between said first and second housing portions.
- 15. A hybrid quick connector assembly comprising:
- an elongated generally tubular male member defining a radially extending abutment surface disposed adjacent an open end thereof, said male member having a male member outer circumferential surface;
- a female member including a first housing portion defining an axial opening for receiving the open end of said male member, a first stepped through passage having a large diameter portion and a small diameter portion, and a first annular bearing surface within said small diameter portion of said first through passage adapted for slip-fit engagement with said male member outer circumferential surface;
- a second housing portion defining a second stepped through passage having a large diameter portion, a small diameter portion and an intermediate diameter portion, said second housing portion including a second annular bearing surface within said small diameter portion of said second through passage adapted for slip-fit engagement with said male member outer circumferential surface;
- said first and second housing portions mechanically interconnected at a joint axially aligning said first and second through passages wherein the small diameter portion of said first housing portion is disposed within the large diameter portion of said second housing portion and one of said housing portions radially locally deformed to establish said joint;
- separate retainer means operative to releasably interconnect said first housing portion and said male member by engaging said male member abutment surface to limit relative axial movement therebetween; and
- sealing means disposed within said second housing portion to effect sealing engagement between said male member outer circumferential surface and an inner circumferential surface of the intermediate diameter portion of said second housing portion, said first and second bearing surfaces axially spaced and straddling said sealings means, with said sealing means sealing said second through passage from said joint between said first and second housing portions.
