This disclosure relates generally to a quick connect assembly for connecting conduit ends for fluid flow.
A quick connect assembly according to an example of the present disclosure includes a first member that has a mating section at a first end. A second member includes a protruding portion received against the mating section. A clip is configured to be received within an opening of the first member such that an engagement portion of the clip is received against the protruding portion.
In a further embodiment of any of the present embodiments, the clip includes an outward portion radially outward of the first member and an engagement portion received against the protruding portion.
In a further embodiment of any of the present embodiments, the mating section includes a radially outward extending surface configured to interface with a first surface of the protruding portion.
In a further embodiment of any of the present embodiments, the engagement portion is received in a slot in the first member axially adjacent to the radially outward extending surface.
In a further embodiment of any of the present embodiments, the clip comprises three engagement portions received in three circumferentially spaced slots in the first member.
A further embodiment of any of the foregoing embodiments includes a radial channel configured to receive the o-ring.
In a further embodiment of any of the present embodiments, the first member is configured to receive a conduit.
In a further embodiment of any of the present embodiments, the clip includes a circumferential opening such that the clip can be attached by moving the clip in a radial direction with respect to the first member.
In a further embodiment of any of the present embodiments, the protruding portion includes a groove configured to receive the engagement portion.
A quick connect assembly according to an example of the present disclosure includes a first member that has a mating section at a first end. A second member includes a protruding portion that has first and second surfaces. The first surface is received against the mating section, and a clip is received against the second surface.
In a further embodiment of any of the present embodiments, the clip includes an outward portion radially outward of the first member and an engagement portion received against the second surface.
In a further embodiment of any of the present embodiments, the clip is received in a slot in the first member.
In a further embodiment of any of the present embodiments, the second surface includes a groove configured to receive an engagement portion of the clip.
A further embodiment of any of the foregoing embodiments includes a radial channel configured to receive the o-ring.
In a further embodiment of any of the present embodiments, the radial channel is axially spaced toward the second end from the radially outward extending surface.
A method for connecting two fluid conduit ends according to an example of the present disclosure includes inserting a male member into a female member. A first surface of a protruding portion of the male member is received against a mating portion of the female member, engaging a clip received against a second surface of the protruding portion.
A further embodiment of any of the foregoing embodiments includes engaging a fluid conduit end to the male member and engaging a second fluid conduit end to the female member.
A further embodiment of any of the foregoing embodiments includes aligning an o-ring within the female member.
These and other features may be best understood from the following specification and drawings, the following which is a brief description.
In one example, the assembly 10 may be used for the transfer of fluid in vehicles. Example fluids include but are not limited to glycol and water.
The male member 14 includes a cylindrical body 36 and a protruding portion 38 extending radially outward from the cylindrical body 36. The male member 14 includes a radially outer surface 40 and a radially inner surface 42. The radially outer surface 40 at the protruding portion 38 may include two radially extending surfaces 44, 46. The surface 44 is configured to mate with the radially inner surface 22 of the female member 12 at the mating section 26. The surface 46, when the male member is received in the female member 12 will be axially aligned with the section 28 and/or the openings 30 in the section 28 or edges 47 of the openings 30 closest to the end 16.
The engagement portions 52A are configured to be received in the openings 30A in the section 28A such that the engagement portions 52A extend radially inward of the inner surface 22A of the female member 12A and engage the surface 46A of the protruding portion 38A of the male member 14A and prevent the male member 14A from moving axially away from the female member 12A, thus keeping the male member 14A and the female member 12A engaged. The mating of the surface 44A of the male member 14A and the inner surface 22A of the female member 12A at the mating section 26A prevents axial movement of the male member in the opposite axial direction.
In one example, the clip 50A is engaged to the female member 12A before the male member 14A is inserted into the female member 12A. The engagement portions 52A engage the ramped surface 44A of the male member as it is being inserted. When the edge 46A becomes aligned with the edge 47A, the engagement portions 52A drop off of the surface 44A and engage the surface 46A.
With axial alignment of the surfaces 47A of the openings 30A with the radially extending surface 46A of the protruding portion 38A when the mating section 26A is engaged with the surface 44A, the engagement portions 52A received against the surface 46A limit axial movement of the male or female members 12, 14 with respect to one another. In one example, the surface 46A forms approximately a 90 degree angle with the adjacent cylindrical surface of the male member 14A to facilitate engagement with the radially extending engagement portions 52A (see
In an example, the clip 50A includes three engagement portions 52A circumferentially spaced from one another by approximately 120° between their respective center points. One of ordinary skill in the art having the benefit of this disclosure would recognize that more or fewer engagement portions 52A and variations in spacing could be utilized. The example clip 50A includes a circumferential opening 55A, such that, after the male member 14A is inserted into the female member 12A, the clip 50A can be engaged with the assembly 10A by moving the clip 50A in a direction substantially perpendicular or radial to the axis A.
The quick connect assembly 10A may further include an o-ring 56A for proper fluid sealing. The o-ring 56A may be received in an annular channel 58A at the radially inner surface 22A of the female member 12A at the cylindrical section 24A. The annular channel 58A may be axially spaced from the mating section 26A toward the end 16A of the female member 12A. The o-ring engages the outer cylinder 40A of the male member 14A when assembled.
Although the different examples have the specific components shown in the illustrations, embodiments of this disclosure are not limited to those particular combinations. It is possible to use some of the components or features from one of the examples in combination with features or components from another one of the examples.
One of ordinary skill in this art would understand that the above-described embodiments are exemplary and non-limiting. That is, modifications of this disclosure would come within the scope of the claims. Accordingly, the following claims should be studied to determine their true scope and content.
