Description

FLUID CONNECTION ASSEMBLYCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit under Articles 4 and 8 of the Stockholm Act of the Paris Convention for the Protection of Industrial Property of U.S. Patent Application No. 63 / 587,808, filed on October 4, 2023, which application is hereby incorporated by reference herein in its entirety.FIELD

[0002] The present disclosure relates to fluid connectors, and more particularly, to a fluid connection assembly including a retainer that decreases the insertion force required for assembly and allows for quick assembly and disassembly without the need for tools.BACKGROUND

[0003] Fluid connectors, fluid connections, and fluid connection assemblies are integral components for many applications, for example in household appliance applications. Household appliances such as refrigerators, dishwashers, washing machines, and coffee makers require not only the supply of water, but also that water be able to travel between components therein. An example of water traveling between components of a coffee maker is water traveling from the inlet to the heater and then to the brew basket. Fluid predominantly moves between components via flexible or rigid hoses which connect to each component by fluid connectors. Such fluid connectors typically include a plastic tube including a barb and a hose clamp that clamps a hose to the barbed tube.

[0004] However, there are many drawbacks with current designs. Current fluid connection designs are difficult to secure due to the small confines of the interior of an appliance and the requirement of tools. Additionally, the barbed tubes are susceptible to failure due to their size and brittle material.SUMMARY

[0047] It is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific assemblies and systems illustrated in the attached drawings and described in the following specification are simply exemplary embodiments of the inventive concepts defined herein. Hence, specific dimensions, directions, or other physical characteristics relating to the embodiments disclosed are not to be considered as limiting, unless expressly stated otherwise. Also, although they may not be, like elements in various embodiments described herein may be commonly referred to with like reference numerals within this section of the application.

[0048] Furthermore, it is understood that this disclosure is not limited to the particular methodology, materials and modifications described and as such may, of course, vary. It is also understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to limit the scope of the claims.

[0049] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure pertains. It should be understood that any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the example embodiments.

[0050] Where used herein, the terms “first,” “second,” and so on, do not necessarily denote any ordinal, sequential, or priority relation, but are simply used to more clearly distinguish one element or set of elements from another, unless specified otherwise.

[0051] Where used herein, the term “about” when applied to a value is intended to mean within the tolerance range of the equipment used to produce the value, or, in some examples, isintended to mean plus or minus 10%, or plus or minus 5%, or plus or minus 1%, unless otherwise expressly specified.

[0052] It should be appreciated that the term “substantially” is synonymous with terms such as “nearly,” “very nearly,” “about,” “approximately,” “around,” “bordering on,” “close to,” “essentially,” “in the neighborhood of,” “in the vicinity of,” etc., and such terms may be used interchangeably as appearing in the specification and claims. It should be appreciated that the term “proximate” is synonymous with terms such as “nearby,” “close,” “adjacent,” “neighboring,” “immediate,” “adjoining,” etc., and such terms may be used interchangeably as appearing in the specification and claims. The term “substantially” is intended to mean values within ten percent of the specified value.

[0053] Where used herein, the term “exemplary” is intended to mean “an example of,” “serving as an example,” or “illustrative,” and does not denote any preference or requirement with respect to a disclosed aspect or embodiment.

[0054] It should be understood that use of “or” in the present application is with respect to a “non-exclusive” arrangement, unless stated otherwise.

A similar interpretation is intended when the phrase “used in at least one of:” is used herein.

[0056] It should be appreciated that the term “tube” as used herein is synonymous with hose, pipe, channel, conduit, tube end form, or any other suitable pipe flow used in hydraulics and fluid mechanics. It should further be appreciated that the term “tube” can mean a rigid or flexible conduit of any material suitable for containing and allowing the flow of a gas or a liquid.

[0057] Adverting now to the figures, FIG. l is a front perspective view of fluid connection assembly 10 in a locked state. FIG. 2 is a front perspective view of fluid connection assembly 10, including release ring 110. FIG. 3 is a front perspective exploded view of fluid connection assembly 10. Fluid connection assembly 10 generally comprises connector body 40 and retainer 80. In an exemplary embodiment, fluid connection assembly 10 further comprises tube 20. In an exemplary embodiment, fluid connection assembly 10 further comprises release ring 110.

[0058] Tube 20 comprises end 22, end 28, radially outward facing surface 24, and through- bore 30. Through-bore 30 extends through tube 20 from end 22 to end 28. Tube 20 is operatively arranged to be fluidly connected to connector body 40, for example via retainer 80. Radially outward facing surface 24 comprises annular groove 26. In an exemplary embodiment, groove 26 is arranged axially between and spaced apart from end 22 and end 28. Tube 20 comprises section 32 axially arranged between end 22 and groove 26, and section 34 axially arranged between groove 26 and end 28. In an exemplary embodiment, radially outward facing surface 24 includes a substantially constant diameter.

[0059] Tube 20 is arranged to be inserted into connector body 40 in axial direction ADI with end 22 first until end 22 engages surface 47, radially outward facing surface 24 engages radially inward facing surface 48, and / or projections 98 engage groove 26. It should be appreciated that tube 20 may be any traditional tube or tube end form comprising a bead, radially outward extending protrusion or flange, or ramp profile, which extends radially outward and axially on the outer surface of the tube, for fluid connection.

[0060] Connector body 40 comprises end 42, end 44, and through-bore 41. Through-bore extends through connector body 40 from end 42 to end 44. Connector body 40 comprises one or more radially inward facing surfaces, for example, radially inward facing surfaces 46, 48, 50, and 52. Radially inward facing surface 46 extends from end 42 in axial direction AD2. In an exemplary embodiment, radially inward facing surface 46 comprises a constant diameter. Radially inward facing surface 48 is connected to radially inward facing surface 46 via surface 47. Surface 47 is an axial surface facing substantially in axial direction AD2. In an exemplary embodiment, radially inward facing surface 48 comprises a constant diameter. Radially inward facing surface 50 is connected to radially inward facing surface 48 via surface 49. Surface 49 is an axial surface facingsubstantially in axial direction AD2. In an exemplary embodiment, radially inward facing surface 48 comprises a constant diameter.

[0061] Radially inward facing surface 52 extends from end 44 in axial direction ADI and is connected to radially inward facing surface 50 via surface 51. Surface 51 is an axial surface facing substantially in axial direction AD2. In an exemplary embodiment, radially inward facing surface 52 comprises a constant diameter. Radially inward facing surface 52 comprises annular groove 54 extending radially outward therefrom. In an exemplary embodiment, groove 54 is arranged axially between and spaced apart from end 44 and surface 51. Groove 54 is operatively arranged to engage projections 94 to secure retainer 80 in connector body 40. In an exemplary embodiment, and as best shown in FIGS. 6-7, the diameter of radially inward facing surface 48 is greater than the diameter of radially inward facing surface 46, the diameter of radially inward facing surface 50 is greater than the diameter of radially inward facing surface 48, and the diameter of radially inward facing surface 52 is greater than the diameter of radially inward facing surface 50.

[0062] Radially outward facing surface 56 extends from end 44 in axial direction ADI . In an exemplary embodiment, radially outward facing surface 56 is connected to end 44 via a frusto- conical surface or chamfer (see FIGS. 6-7). In an exemplary embodiment, radially outward facing surface 56 comprises a constant diameter surface. Radially outward facing surface 58 extends from end 42 in axial direction AD2 and is connected to radially outward facing surface 56 via an axial surface. In an exemplary embodiment, radially outward facing surface 58 may be connected to radially outward facing surface 56 via an axial surface and a frusto-conical surface. Radially outward facing surface 58 comprises annular barb or protrusion 60. In an exemplary embodiment, barb 60 is arranged axially between and spaced apart from end 42 and radially outward facing surface 56. Radially outward facing surface 58 and barb 60 are operatively arranged to facilitate fluid connection of connector body 40 to a fluid conduit (e.g., a hose or tube) via a connector, for example, a hose clamp.

[0063] In an exemplary embodiment, fluid connection assembly 10 further comprises at least one seal, for example seal 62. Seal 62 is arranged in connector body 40 to provide a fluid tight seal between connector body 40 and tube 20. In an exemplary embodiment, seal 62 is arranged in connector body 40 such that it is engaged with surface 49 and radially inward facing surface 50. When fluid connection assembly 10 is assembled, seal 62 is engaged with and / or squeezed between, radially inward facing surface 50 and radially outward facing surface 24 (see FIGS. 6-7).

[0064] In an exemplary embodiment, fluid connection assembly 10 further comprises at least one spacer, for example, spacer or bushing 70. Spacer 70 comprises end 72, end 74, through-bore 71 extending from end 72 to end 74, radially outward facing surface 76, and radially inward facing surface 78. In an exemplary embodiment, radially inward facing surface 78 is connected to end 72 via a frusto-conical surface and / or radially inward facing surface 78 is connected to end 74 via a frusto-conical surface. Spacer 70 is operatively arranged to maintain the position of seal 62 in connector body 40. For example, when fluid connection assembly 10 is assembled, and as shown in FIGS. 6-7, end 72 is engaged with surface 51, radially outward facing surface 76 is engaged with radially inward facing surface 52, end 74 is engaged with end 82, and / or radially inward facing surface 78 is engaged with radially outward facing surface 24. The engagement of end 72 with surface 51 maintains seal 62 axially between surface 49 and end 72 (i.e., thereby forming a seal gland or groove).

[0065] FIG. 4A is a front perspective view of retainer 80. FIG. 4B is a rear perspective view of retainer 80. FIG. 4C is a side elevational view of retainer 80. FIG. 4D is a rear elevational view of retainer 80. Retainer 80 comprises end 82, end 84, through-bore 81, radially outward facing surface 86, and radially inward facing surface 88. Through-bore 81 extends through retainer 80 from end 82 to end 84. Radially outward facing surface 86 is operatively arranged to engage radially inward facing surface 52 of connector body 40. In an exemplary embodiment, radially outward facing surface 86 comprises a constant diameter. In an exemplary embodiment, and as best shown in FIGS. 4C and 6-7, radially outward facing surface 86 is connected to end 82 via a frusto-conical surface. In an exemplary embodiment, radially inward facing surface 88 comprises a constant diameter. In an exemplary embodiment, radially inward facing surface 88 comprises radially inward extending protrusion or bead 89. Protrusion 89 is arranged to engage protrusion 125 to maintain release ring 110 within retainer 80, as will be described in greater detail below. In an exemplary embodiment, protrusion 89 is axially arranged between end 84 and projections 98.

[0066] Retainer 80 further comprises one or more slots 90. In an exemplary embodiment, slots 90 are circumferentially spaced and extend from end 84. Slots 90 form fingers 92 arranged circumferentially therebetween. For example, in circumferential direction CD1 (or circumferential direction CD2), fingers 92 and slots 90 alternate such that one slot 90 is arranged between two fingers 92 and / or one finger 92 is arranged between two slots 90. In an exemplary embodiment, each slot 90 comprises linear side 90A, linear side 90B, and curvilinear side 90C (see FIG. 4C). Curvilinear side 90C forms the bottom or end of slot 90 and connects linear side 90A and linear side 90B. Due to the arrangement of slots 90, fingers 92 are elastically displaceable in radial direction RD1 and radial direction RD2, for example, with respect to radially outward facing surface 86 proximate end 82. Such elastic deformation of fingers 92 allows retainer 80 to beinserted into and connected to connector body 40 with relatively low insertion force. In an exemplary embodiment, retainer 80 comprises a continuous ring (i.e., proximate end 82).

[0067] Each of fingers 92 comprises protrusion 94 extending radially outward therefrom (i.e., radially outward from radially outward facing surface 86). Protrusion 94 comprises ramp surface 96. In an exemplary embodiment, protrusion 94 further comprises an axial surface facing in axial direction AD2. In an exemplary embodiment, protrusion 94 further comprises a radially outward facing surface connecting the axial surface and ramp surface 96. Ramp surface 96 is a tapered surface extending radially outward in axial direction AD2. In an exemplary embodiment, ramp surface 96 is curvilinear in a circumferential direction. Ramp surface 96 is operatively arranged to engage connector body 40, for example radially inward facing surface 52, to force fingers 92 radially inward during insertion of retainer 80 into connector body 40. Once protrusions 94 are aligned with groove 54, fingers 92 snap back radially outward to their original position and protrusions 94 are engaged with groove 54 to prevent retainer 80 from being removed from connector body 40. As shown in FIGS. 4C and 6, ramp surface 96 is arranged at angle a with respect to radially outward facing surface 86. In an exemplary embodiment, angle a is an acute angle, for example, 45 degrees.

[0068] As best shown in FIG. 4C, protrusion 94, and specifically ramp surface 96, is spaced apart in axial direction AD2 from end 82 by distance LI. Protrusion 94 is spaced apart in axial direction ADI from end 84 by distance L2. In an exemplary embodiment, distance LI is greater than distance L2. Ramp surface 96 is spaced apart in axial direction AD2 from side 90C by distance L3. In an exemplary embodiment, distance L2 is greater than distance L3. The spacing of protrusion 94 from side 90C allows for optimal deflection and resiliency of fingers 92 when installing retainer 80 in connector body 40. For example, the small offset of ramp surface 96 from side 90C allows elastic deformation of fingers 92 in a radial inward direction, but not so much as to cause possible plastic deformation or accidental removal of retainer 80 from connector body 40. It should be appreciated that since fingers 92 are circumferentially spaced, protrusions 94 are also circumferentially spaced.

[0069] Each of fingers 92 comprises projection 98 extending radially inward therefrom (i.e., radially inward from radially inward facing surface 88). Projection 98 comprises ramp surface 100 and end 102. Ramp surface 100 is a tapered surface extending radially inward in axial direction ADI. In an exemplary embodiment, ramp surface 100 is curvilinear in a circumferential direction. Ramp surface 100 is operatively arranged to engage tube 20, for example, radially outward facing surface 24, to force projections 98 radially outward during insertion of tube 20 into retainer 80 and connector body 40. Once projections 98 are aligned with groove 26, projections snap back radially inward to their original position and projections 98, specificallyends 102, are engaged with groove 26 to prevent tube 20 from being removed from retainer 80 and connector body 40. As shown in FIG. 6, ramp surface 100 is arranged at angle P with respect to radially inward facing surface 88. In an exemplary embodiment, angle P is an acute angle, for example, 30 degrees.

[0070] As best shown in FIGS. 4B and 6-7, radial space SI is formed radially between projections 98 and radially inward facing surface 88. Such radial space SI allows for sufficient elastic deformation of projections 98 in a radially outward direction. Additionally, ends 102 are spaced apart in axial direction AD2 from end 82 by distance L4. This spacing is important because it allows end 82 to engage spacer 70 without hindering the elastic deformability of projections 98. It should be appreciated that since fingers 92 are circumferentially spaced, projections 98 are also circumferentially spaced.

[0071] As shown in FIG. 4D, the radially innermost portions of projections 98, for example ends 102, comprise diameter DI. Radially inward facing surface 88 comprises diameter D2, which is greater than diameter DI. Radially outward facing surface 86 comprises diameter D3, which is greater than diameter D2. The radially outermost portion of protrusions 94 comprises diameter D4, which is greater than diameter D3.

[0072] FIG. 5A is a rear perspective view of release ring 110. FIG. 5B is a front perspective view of release ring 110. Release ring 110 is operatively arranged to release or disconnect tube 20 from retainer 80 and connector body 40. Release ring 110 comprises a plate portion, engaging portion 120, through-bore 111, and radially inward facing surface 118. The plate portion comprises end or surface 112, end or surface 114, and radially outward facing surface 116.

[0073] Engaging portion 120 is connected to surface 112 and extends therefrom in axial direction ADI. Engaging portion 120 comprises end 122 and at least one radially outward facing surface, for example, radially outward facing surfaces 124 and 126. Radially outward facing surface 124 extends from surface 112 in axial direction ADI and comprises a constant diameter. In an exemplary embodiment, the diameter of radially outward facing surface 124 is less than the diameter of radially outward facing surface 116. In an exemplary embodiment, and as best shown in FIG. 7, the diameter of radially outward facing surface 124 is less than diameter D2 (i.e., the diameter of radially inward facing surface 88).

[0074] Radially outward facing surface 126 is a frusto-conical surface connecting radially outward facing surface 124 with end 122. Radially outward facing surface 126 extends radially inward in axial direction ADI. Radially outward facing surface 126 is operatively arranged to engage ramp surfaces 100 to gradually displace projections 98 radially outward to disengage groove 26. Release ring 110 may further comprises radially outward extending protrusion or bead 125. In an exemplary embodiment, protrusion 125 is arranged at a position where radially outwardfacing surface 126 meets radially outward facing surface 124. Protrusion 125 is operatively arranged to engage protrusion 89 such that release ring 110 is connected to retainer 80. In an exemplary embodiment, the outermost diameter of protrusion 125 is greater than the innermost diameter of protrusion 89. In an exemplary embodiment, surface 112 is arranged to engage end 44 to indicate to the user that release ring 110 is fully and adequately engaged with retainer 80 and tube 20 can be removed.

[0075] In an exemplary embodiment, release ring 110 further comprises a plurality of circumferentially spaced ribs 128. Ribs 128 extend radially outward from radially outward facing surface 124. Ribs 128 extend from surface 112 in axial direction ADI. Ribs 128 are operatively arranged to engage slots 90. It should be appreciated that, in an exemplary embodiment, release ring 110 may be translatably connected to retainer 80, or translatably arranged on tube 20. Such arrangements allow a user to quickly and easily disconnect tube 20 from connector body 40.

[0076] To assemble fluid connection assembly 10, retainer 80 is inserted end 82 first into connector body 40 in axial direction ADI. As ramp surfaces 96 engage radially inward facing surface 52 and / or end 44, fingers 92 displace radially inward until protrusions 94 are aligned with groove 54, at which point fingers 92 snap back radially outward and protrusions 94 engage groove 54. The engagement of protrusions 94 with groove 54 prevents retainer 80 from being removed from connector body 40. End 82 of retainer engages end 74 of spacer 70. End 72 of spacer 70 engages seal 62 (i.e., end 72 forms a groove with surface 49 to maintain seal 62 therein).

[0077] Release ring 110 is then inserted into retainer 80, with end 122 first, in axial direction ADI. Radially outward facing surface 124 engages radially inward facing surface 88. Release ring 110 is forced in axial direction ADI until protrusion 125 is axially arranged between protrusion 89 and ramp surfaces 100, which maintains release ring 110 within retainer 80.

[0078] Tube 20 is inserted end 22 first through release ring 110 and into retainer 80 in axial direction ADI. As end 22 and / or radially outward facing surface 24 engages ramp surfaces 100, projections 98 displace radially outward until ends 102 are aligned with groove 26, at which point projections 98 snap back radially inward and projections 98 engage groove 26. The engagement of projections 98 with groove 26 prevents tube 20 from being removed from retainer 80 and connector body 40.

[0079] To disassemble fluid connection assembly 10, release ring 110 is displaced in axial direction ADI. In an exemplary embodiment, ribs 128 are circumferentially aligned with slots 90. Radially outward facing surface 126 is engaged with ramp surfaces 100 to force projections 98 radially outward to disengage groove 26. Tube 20 can then be removed from retainer 80, and connector body 40, in axial direction AD2.

In an exemplary embodiment, radially outward facing surface 224 includes a substantially constant diameter. In an exemplary embodiment, radially outward facing surface 224 is connected to end 222 via frusto-conical surface 236.

[0082] Tube 220 is arranged to be inserted into connector body 240 in axial direction ADI with end 222 first until end 222 engages surface 247, radially outward facing surface 224 engages radially inward facing surface 248, and / or projections 298 engage groove 226. It should be appreciated that tube 220 may be any traditional tube or tube end form comprising a bead, radially outward extending protrusion or flange, or ramp profile, which extends radially outward and axially on the outer surface of the tube, for fluid connection.

[0083] Connector body 240 comprises end 242, end 244, and through-bore 241. Through- bore extends through connector body 240 from end 242 to end 244. Connector body 240 comprises one or more radially inward facing surfaces, for example, radially inward facing surfaces 246,248, 250, and 252. Radially inward facing surface 246 extends from end 242 in axial direction AD2. In an exemplary embodiment, radially inward facing surface 246 comprises a constant diameter.

Surface 251 is an axial surface facing substantially in axial direction AD2. In an exemplary embodiment, radially inwardfacing surface 252 comprises a constant diameter. Radially inward facing surface 252 comprises annular groove 254 extending radially outward therefrom. In an exemplary embodiment, groove 254 is arranged axially between and spaced apart from end 244 and surface 251. Groove 254 is operatively arranged to engage projections 294 to secure retainer 280 in connector body 240. In an exemplary embodiment, and as best shown in FIG. 12, the diameter of radially inward facing surface 248 is greater than the diameter of radially inward facing surface 246, the diameter of radially inward facing surface 250 is greater than the diameter of radially inward facing surface 248, and the diameter of radially inward facing surface 252 is greater than the diameter of radially inward facing surface 250.

[0085] Radially outward facing surface 256 extends from end 244 in axial direction ADI. In an exemplary embodiment, radially outward facing surface 256 is connected to end 244 via a frusto-conical surface or chamfer (see FIG. 12). In an exemplary embodiment, radially outward facing surface 256 comprises a constant diameter surface. Radially outward facing surface 258 extends from end 242 in axial direction AD2 and is connected to radially outward facing surface 256 via an axial surface. In an exemplary embodiment, radially outward facing surface 258 may be connected to radially outward facing surface 256 via an axial surface and a frusto-conical surface. Radially outward facing surface 258 comprises annular barb or protrusion 258. In an exemplary embodiment, barb 258 is arranged axially between and spaced apart from end 242 and radially outward facing surface 256. Radially outward facing surface 258 and barb 260 are operatively arranged to facilitate fluid connection of connector body 240 to a fluid conduit (e.g., a hose or tube) via a connector, for example, a hose clamp.

[0086] In an exemplary embodiment, fluid connection assembly 210 further comprises at least one seal, for example seal 262. Seal 262 is arranged in connector body 240 to provide a fluid tight seal between connector body 240 and tube 220. In an exemplary embodiment, seal 262 is arranged in connector body 240 such that it is engaged with surface 249 and radially inward facing surface 250. When fluid connection assembly 210 is assembled, seal 262 is engaged with and / or squeezed between, radially inward facing surface 250 and radially outward facing surface 224 (see FIG. 12).

[0087] In an exemplary embodiment, fluid connection assembly 210 further comprises at least one spacer, for example, spacer or bushing 270. Spacer 270 comprises end 272, end 274, through-bore 271 extending from end 272 to end 274, radially outward facing surface 276, and radially inward facing surface 278. In an exemplary embodiment, radially inward facing surface 278 is connected to end 272 via a frusto-conical surface and / or radially inward facing surface 278 is connected to end 274 via a frusto-conical surface. Spacer 270 is operatively arranged to maintain the position of seal 262 in connector body 240. For example, when fluid connection assembly 210is assembled, and as shown in FIG. 12, end 272 is engaged with surface 251, radially outward facing surface 276 is engaged with radially inward facing surface 252, end 274 is engaged with end 282, and / or radially inward facing surface 278 is engaged with radially outward facing surface 224. The engagement of end 272 with surface 251 maintains seal 262 axially between surface 249 and end 272 (i.e., thereby forming a seal gland or groove).

[0088] FIG. 10A is a front perspective view of retainer 280. FIG. 1 OB is a rear perspective view of retainer 280. FIG. 10C is a side elevational view of retainer 280. FIG. 10D is a rear elevational view of retainer 280. Retainer 280 comprises end 282, end 284, through-bore 281, radially outward facing surface 286, and radially inward facing surface 288. Through-bore 281 extends through retainer 280 from end 282 to end 284. Radially outward facing surface 286 is operatively arranged to engage radially inward facing surface 252 of connector body 240. In an exemplary embodiment, radially outward facing surface 286 comprises a constant diameter. In an exemplary embodiment, and as best shown in FIGS. 10C and 12, radially outward facing surface 286 is connected to end 282 via a frusto-conical surface. In an exemplary embodiment, radially inward facing surface 288 comprises a constant diameter. In an exemplary embodiment, radially inward facing surface 288 comprises radially inward extending protrusion or bead 289. Protrusion 289 is arranged to engage protrusion 325 to maintain release ring 310 within retainer 280, as will be described in greater detail below. In an exemplary embodiment, protrusion 289 is arranged at end 284.

[0089] Retainer 280 further comprises one or more slots 290. In an exemplary embodiment, slots 290 are circumferentially spaced and extend from end 284. Slots 290 form fingers 292 arranged circumferentially therebetween. For example, in circumferential direction CD1 (or circumferential direction CD2), fingers 292 and slots 290 alternate such that one slot 290 is arranged between two fingers 292 and / or one finger 292 is arranged between two slots 290. In an exemplary embodiment, each slot 290 comprises linear side 290A, linear side 290B, and curvilinear side 290C (see FIG. 10C). Curvilinear side 290C forms the bottom or end of slot 290 and connects linear side 290 A and linear side 290B. Due to the arrangement of slots 290, fingers 292 are elastically displaceable in radial direction RD1 and radial direction RD2, for example, with respect to radially outward facing surface 286 proximate end 282. Such elastic deformation of fingers 292 allows retainer 280 to be inserted into and connected to connector body 240 with relatively low insertion force. In an exemplary embodiment, retainer 280 comprises a continuous ring.

[0090] Each of fingers 292 comprises one or more protrusions 294 extending radially outward therefrom (i.e., radially outward from radially outward facing surface 286). Protrusion 294 comprises ramp surface 296. In an exemplary embodiment, protrusion 294 further comprisesramp surface 297. In an exemplary embodiment, protrusion 294 further comprises a radially outward facing surface connecting ramp surface 96 and ramp surface 297. Ramp surface 296 is a tapered surface extending radially outward in axial direction AD2. Ramp surface 297 is a tapered surface extending radially outward in axial direction ADI. In an exemplary embodiment, ramp surface 296 is curvilinear in a circumferential direction. Ramp surface 296 is operatively arranged to engage connector body 240, for example radially inward facing surface 252, to force fingers 292 radially inward during insertion of retainer 280 into connector body 240. Once protrusions 294 are aligned with groove 254, fingers 292 snap back radially outward to their original position and protrusions 294 are engaged with groove 254 to prevent retainer 280 from being removed from connector body 240. As shown in FIG. 10C, ramp surface 296 is arranged at angle y with respect to radially outward facing surface 286. In an exemplary embodiment, angle y is an acute angle, for example, 45 degrees. Ramp surface 297 facilitates the removal of retainer 280 from connector body 240.

[0091] As best shown in FIG. 10C, protrusion 294, and specifically ramp surface 296, is spaced apart in axial direction AD2 from end 282 by distance L5. Protrusion 294 is spaced apart in axial direction ADI from end 284 by distance L6. In an exemplary embodiment, distance L5 is greater than distance L6. Ramp surface 296 is spaced apart in axial direction AD2 from side 290C by distance L7. In an exemplary embodiment, distance L6 is greater than distance L7. The spacing of protrusion 294 from side 290C allows for optimal deflection and resiliency of fingers 292 when installing retainer 280 in connector body 240. For example, the small offset of ramp surface 296 from side 290C allows elastic deformation of fingers 292 in a radial inward direction, but not so much as to cause possible plastic deformation or accidental removal of retainer 280 from connector body 240. It should be appreciated that since fingers 292 are circumferentially spaced, protrusions 294 are also circumferentially spaced.

[0092] Each of fingers 292 comprises projection 298 extending radially inward therefrom (i.e., radially inward from radially inward facing surface 288). Projection 298 comprises ramp surface 300 and end 302. Ramp surface 300 is a tapered surface extending radially inward in axial direction ADI. In an exemplary embodiment, ramp surface 300 is curvilinear in a circumferential direction. Ramp surface 300 is operatively arranged to engage tube 220, for example, radially outward facing surface 224, to force projections 298 radially outward during insertion of tube 220 into retainer 280 and connector body 240. Once projections 298 are aligned with groove 226, projections snap back radially inward to their original position and projections 298, specifically ends 302, are engaged with groove 226 to prevent tube 220 from being removed from retainer 280 and connector body 240. As shown in FIG. 12, ramp surface 300 is arranged at angle 5 with respectto radially inward facing surface 288. In an exemplary embodiment, angle 5 is an acute angle, for example, 30 degrees.

[0093] As best shown in FIGS. 10B and 12, radial space S2 is formed radially between projections 298 and radially inward facing surface 288. Such radial space S2 allows for sufficient elastic deformation of projections 298 in a radially outward direction. Additionally, ends 302 are spaced apart in axial direction AD2 from end 282 by distance L8. This spacing is important because it allows end 282 to engage spacer 270 without hindering the elastic deformability of projections 298. It should be appreciated that since fingers 292 are circumferentially spaced, projections 298 are also circumferentially spaced.

[0094] As shown in FIG. 10D, the radially innermost portions of projections 298, for example ends 302, comprise diameter D5. Radially inward facing surface 288 comprises diameter D6, which is greater than diameter D5. Radially outward facing surface 286 comprises diameter D7, which is greater than diameter D6. The radially outermost portion of protrusions 294 comprises diameter D8, which is greater than diameter D7.

[0095] FIG. 11A is a rear perspective view of the release ring 310. FIG. 1 IB is a front perspective view of release ring 310. Release ring 310 is operatively arranged to release or disconnect tube 220 from retainer 280 and connector body 240. Release ring 310 comprises a plate portion, engaging portion 320, through-bore 311, and radially inward facing surface 318. The plate portion comprises end or surface 312, end or surface 314, and radially outward facing surface 316.

[0096] Engaging portion 320 is connected to surface 312 and extends therefrom in axial direction ADI. Engaging portion 320 comprises end 322 and at least one radially outward facing surface, for example, radially outward facing surfaces 324, 325, 326, and 327. Radially outward facing surface 324 extends from surface 312 in axial direction ADI and comprises a constant diameter. In an exemplary embodiment, the diameter of radially outward facing surface 324 is less than the diameter of radially outward facing surface 316. In an exemplary embodiment, the diameter of radially outward facing surface 324 is less than diameter D6 (i.e., the diameter of radially inward facing surface 288).

[0097] Radially outward facing surface 327A is a curvilinear surface connected to radially outward facing surface 324 and extending in axial direction ADI. Radially outward facing surface 327A decreases in diameter in axial direction ADI . Radially outward facing surface 327B extends from radially outward facing surface 327A. Radially outward facing surface 326 is a frusto-conical surface connecting radially outward facing surface 327B with end 322. Radially outward facing surface 326 extends radially inward in axial direction ADI. Radially outward facing surface 326 is operatively arranged to engage ramp surfaces 300 to gradually displace projections 298 radially outward to disengage groove 226. Release ring 310 may further comprises radially outwardextending protrusion or bead 325. In an exemplary embodiment, protrusion 325 is arranged on radially outward facing surface 324. In an exemplary embodiment, protrusion 325 is arranged at a position where radially outward facing surface 327A meets radially outward facing surface 324. Protrusion 325 is operatively arranged to engage protrusion 289 such that release ring 310 is connected to retainer 280. In an exemplary embodiment, the outermost diameter of protrusion 325 is greater than the innermost diameter of protrusion 289. In an exemplary embodiment, surface 312 is arranged to engage end 244 to indicate to the user that release ring 310 is fully and adequately engaged with retainer 280 and tube 220 can be removed.

[0098] In an exemplary embodiment, release ring 310 further comprises a plurality of circumferentially spaced ribs 328. Ribs 328 extend radially outward from radially outward facing surface 324, radially outward facing surface 327 A, and / or radially outward facing surface 327B. Ribs 328 extend from surface 312 in axial direction ADI. Ribs 328 are operatively arranged to engage slots 290. It should be appreciated that, in an exemplary embodiment, release ring 310 may be translatably connected to retainer 280, or translatably arranged on tube 220. Such arrangements allow a user to quickly and easily disconnect tube 220 from connector body 240.

[0099] To assemble fluid connection assembly 210, retainer 280 is inserted end 282 first into connector body 240 in axial direction ADI. As ramp surfaces 296 engage radially inward facing surface 252 and / or end 244, fingers 292 displace radially inward until protrusions 294 are aligned with groove 254, at which point fingers 292 snap back radially outward and protrusions 294 engage groove 254. The engagement of protrusions 294 with groove 254 prevents retainer 280 from being removed from connector body 240. End 282 of retainer engages end 274 of spacer 270. End 272 of spacer 270 engages seal 262 (i.e., end 272 forms a groove with surface 249 to maintain seal 262 therein).

[0100] Release ring 310 is then inserted into retainer 280, with end 322 first, in axial direction ADI. Radially outward facing surface 324 engages radially inward facing surface 288. Release ring 310 is forced in axial direction ADI until protrusion 325 is axially arranged between protrusion 289 and ramp surfaces 300, which maintains release ring 310 within retainer 280.

[0101] Tube 220 is inserted end 222 first through release ring 310 and into retainer 280 in axial direction ADI . As end 222 and / or radially outward facing surface 224 engages ramp surfaces 300, projections 298 displace radially outward until ends 302 are aligned with groove 226, at which point projections 298 snap back radially inward and projections 298 engage groove 226. The engagement of projections 298 with groove 226 prevents tube 220 from being removed from retainer 280 and connector body 240.

[0102] To disassemble fluid connection assembly 210, release ring 310 is displaced in axial direction ADI. In an exemplary embodiment, ribs 328 are circumferentially aligned withslots 290. Radially outward facing surface 326 and / or radially outward facing surface 237B is engaged with ramp surfaces 300 to force projections 298 radially outward to disengage groove 226. Tube 220 can then be removed from retainer 280, and connector body 240, in axial direction AD2.
