US Patent:

6851725, Feb 8, 2005

Filed:

Nov 6, 2002

Appl. No.:

10/288754

Inventors:

Matthew David Lutzke - Fenton MI, US

Assignee:

Cooper Technology Services, LLC - Findlay OH

International Classification:

F16L037/00

US Classification:

285305, 285921

Abstract:

A tube is insertable into a housing and secured by a collet connector. The tube has a first upset portion for actuating the collet and a second upset portion outwardly from the first upset portion. A retention clip has a first pair of arms which attach to a portion of the housing and a second pair of arms which attach to the tube outwardly of the second upset portion to further secure the tube within the housing. The end of each of the second pair of arms include a ramped surface. If the tube is not fully inserted within the housing before attaching clip, and thus the first upset portion has not fully actuated the collet, the ramps will cam along the second upset portion, thus pushing the tube into the housing and likewise the first upset portion through the collet.

Assignee:

Cooper Technology Services, LLC - Findlay OH

International Classification:

F16L 37/00

US Classification:

285321, 285307

Abstract:

A collet quick connect fluid coupling includes a self-centering structure that is received within a channel () in a pilot (). The channel and self-centering leg () ensures the collet () is approximately centered within the housing () as a tube () is moved into the housing. This prevents misalignment of the collet relative to the tube (). In a preferred embodiment, the collet () has a ramp () on an inwardly facing surface that cams along a surface on the pilot (), assisting the collet () in expanding when a tube () is moved into a housing ().

Inventors:

Matthew D. Lutzke - Clarkston MI, US
Justin L. Gauthier - Shelby Township MI, US

International Classification:

F16L 37/12

US Classification:

285119

Abstract:

A quick connector assembly () includes a coupling housing () having a fluid quick connector () disposed about an end () and a sensor quick connector () axially aligned with an auxiliary axis (A). A sensor housing () is insertable along the auxiliary axis (A) to couple a sensor with the coupling housing (). The sensor quick connector () includes at least one leg () and the sensor housing () includes a locking barb () extending radially outwardly to flex the leg () during axial movement of the sensor housing (). The leg () includes a mechanical stop () and the locking barb () includes a shoulder () for engaging the mechanical stop () to establish an interlocked position of the housings () and prevent rotational movement of the sensor housing () about the auxiliary axis (A).

Inventors:

Brian Parks - Howell MI, US
Matthew Lutzke - Clarkston MI, US

International Classification:

F16L 37/02

US Classification:

285319

Abstract:

A quick connector assembly for quickly connecting and establishing fluid communication between a male end form having a bead and a hose or any other type of tube. The quick connector assembly includes a housing having a stem portion for receiving the hose and a female receiving portion for receiving the male end form. A plunger is disposed within the housing, and the plunger is biased in a first direction by a spring. The quick connector further includes a locker which is held in a non-engaged position until the male end form has been inserted into the housing until the bead moves the plunger in a second direction opposite of the first direction. Once the bead of the male end form clears the locker, the locker can be moved into an engaged position with the bead of the male end form being trapped between the locker and the plunger.

International Classification:

F16L 37/133

US Classification:

285319

Abstract:

A quick connector assembly for quickly connecting and establishing fluid communication between a male end form having a bead and a tube. The quick connector assembly includes a housing having a stem portion for receiving the hose and a female receiving portion for receiving the male end form. The quick connector includes a locker which is moveable between a non-engaged position for allowing the male end form to be inserted into or withdrawn from the quick connector assembly and an engaged position for trapping the male end form in the quick connector assembly. The locker includes a pair of outside legs, each having a notch, and the housing includes a pair of windows for receiving the notches when the locker is in the engaged position. The locker cannot be moved back to the non-engaged position until the outside legs are pulled outwardly, thereby disengaging the notches from the windows.

Matthew David LUTZKE - Clarkston MI, US

International Classification:

F16L 37/02
F16L 37/08

Abstract:

A quick connector (QC) assembly is provided, and comprises a housing defining a fluid passageway extending along an axis at an open end, a retainer ring disposed in the open end and defining a slot, a retainer clip secured to the housing and at least partially disposed within the fluid passageway at the open end, and a verification tab disposed within the slot. The tab is slideably displaceable along the slot between a negative position, where the tab is completely disposed within the housing, and a positive position, where a portion of the tab is visibly disposed above an exterior surface of the housing. A method for connecting and establishing fluid communication between components with the QC assembly is also provided.

International Classification:

F16L 41/02
F16L 37/133

Abstract:

The fluid connector assembly includes a connector body with an intermediate portion that extends between opposite end portions and has a first bore. The connector body has an elongated wall that projects outwardly from the intermediate portion and that surrounds a second bore which opens to the first bore. A flat tube, which is made of a second material that is different than the first material and has at least one fluid passage, is in fluid communication with the second bore of the connector body. The flat tube has generally flat side walls and is lockingly retained with the connector body by male and female locking structures that cooperate with one another.
