Definitions
- Fluid connectors include a type known as a quick connect coupling.
- a quick connect coupling generally includes a resilient portion that is biased away from a relaxed position by a fluid handling member such as a tube.
- the tube includes an upset or enlarged portion that passes through the quick connect retainer, moving the resilient portion of the quick connect retainer away from the relaxed position. Once the upset portion has passed this portion, the portion can move back to its relaxed position, now securing the tube within a housing structure.
- One type of quick connect retainer is a collet retainer.
- the retainer In a collet retainer, the retainer is generally cylindrical, with an expansion gap through the collet retainer at one circumferential position. As the upset portion engages the collet retainer, the collet retainer expands at this expansion gap, such that the upset portion can pass. Once the upset portion has passed the collet retainer, the collet retainer returns to its relaxed position, outward of the upset portion, and retaining the tube within the housing. Collet retainers have gained much success. However, one challenge with a collet retainer is that it can be off-center within a housing opening. When this occurs, and the tube is moved into the housing, the tube may sometimes move the collet retainer even further away from an acceptable position. This is of course undesirable.
- a collet retainer is provided with self-centering structure to hold the collet retainer in an approximately centered position in the housing until the tube is inserted into the housing.
- the self-centering structure includes a leg extending from the retainer portion of the collet that fits into a channel.
- the channel is preferably formed within a pilot positioned inward of the collet retainer.
- the collet retainer preferably has a ramp surface facing inward that cams along a guiding surface as the collet is brought inwardly by the upset portion of the tube. The ramp surface assists in the collet retainer being cammed to its opened position.
- the upset portion is more easily moved beyond the collet retainer.
- it is the pilot positioned inwardly of the collet retainer that causes the ramp surface to be cammed outwardly.
- Figure 1 is a cross-sectional view through a fluid handling assembly.
- Figure 2 is a front view of a collet retainer according to this invention.
- Figure 3 is a cross-sectional view through Figure 2.
- Figure 4 shows a feature of the collet retainer as a tube is being inserted.
- DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A fluid handling assembly 20 is illustrated in Figure 1.
- a housing 22 includes an outer structure 24 retaining a collet retainer 26.
- Collet retainer 26 is formed with an axially inwardly extending leg 28. Further, an inward-facing surface of the collet retainer 26 is formed at a ramp angle.
- this angle is at 45° relative to a central axis of the collet retainer 26.
- a pilot 32 has an inner end 34 that faces the ramp surface 30.
- a channel 36 is formed in the pilot 32.
- the leg 28 is received within the channel 36. The positioning of the leg 28 within the channel 36 ensures that the collet retainer remains at least approximately centered within the housing 22 until insertion of the tube 38.
- the tube 38 is formed with an upset portion 40 that moves inward of the housing 22, and past the collet retainer 26, such that it is secured as shown in Figure 1.
- Figure 2 is a front view of the collet retainer 26.
- a collet retainer has an expansion gap 44 between two circumferential ends.
- FIG. 3 is a cross-sectional view through the collet 26, and shows the ramp surface 30, and the centering leg 28. As shown in Figure 4, as the tube 38 is being inserted, the upset portion 26 initially contacts an outer surface of the collet retainer 26. The upset portion 44 will carry the collet retainer inwardly until the ramp surface 30 engages end 34 of the pilot 32.
- the ramp surface 30 will cam along end 34, causing the collet retainer 26 to expand radially outwardly about the groove 42, and separating at gap 44 to be circumferentially larger such that the upset portion 40 can move beyond the collet retainer 26. At that point, the collet retainer 26 will snap back inwardly to its relaxed position, outward of the upset portion 40 and holding the tube 38 as shown in Figure 1.
- the present invention ensures the collet retainer is properly positioned in the housing 22 prior to insertion of the tube.
- the ramp surface 30 assists this radially outward expansion.
