Description

[0001] Priority declaration

[0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 63 / 339,164, filed on May 6, 2022, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates generally to plumbing fittings. More particularly, the present disclosure relates to an apparatus and method for assembling a push-fit type connection fitting having improved blowout resistance. Background Art

[0004] Tubes are used to transport various liquids and / or gases. Couplers, connectors, and fittings are used to connect tubes in various ways so that the tubes can be arranged in different configurations to move the media through the tubes. Tubes can be hard or rigid, such as metal or plastic pipes used in domestic plumbing applications, or the tubes can be flexible. Connectors are used for end-to-end connection of tubes, or these connectors can lay out the tubes in different directions relative to the axis of the tube. For example, connectors can be used to change the direction of the pipe, such as changing a 45° or 90° angle relative to the flow channel of the pipe to which the connector is connected. Connectors can also be used to branch or split pipes in different directions. For example, single pipe sections can be connected by T-fittings or Y-fittings or multi-tube joints or diameter changes. Summary of the invention

[0005] The present disclosure relates to connectors for pipes that have, among other advantages, improved ease of assembly and coupling. Some pipe connectors may be difficult to assemble or require special tools to couple the connector to the pipe. For example, a threaded connector may require a wrench to hold one component while rotating the mating components. Therefore, there is a need for a connector that does not require tools to couple with the pipe, so that a substantially watertight seal can be manually achieved between the connector and the pipe without the need for tools.

[0006] In addition, some existing connectors require deformation to connect two parts or to connect the connector to a tube. For example, the end of a garden hose has the exterior of a hose bib that is crimped around the exterior of the tube to connect a male or female hose bib to the garden hose. In some connectors, the user must manually deform the end of the sleeve so that the two parts of the connector cannot be axially separated, thereby securing the parts of the connector together. Therefore, a simpler connector that does not require manual deformation to connect the parts is needed.

[0007] Some connectors are irreversibly coupled to the pipe and cannot be removed without destroying the connector. Welding or soldering pipe joints are historical examples of permanent connectors. However, it may be advantageous to remove the pipe and reuse the connector. Therefore, there is a need for a connector that can be removed without damaging the connector. Connectors according to the embodiments discussed below address these issues.

[0008] It is desirable that fluid connectors not leak, since leaks can result in, for example, system pressure loss or liquid pooling.Connectors according to embodiments discussed below are configured to provide a fluid tight seal at least at pressures several times greater than the expected operating pressure of the tubular connector.

[0009] The following various exemplary descriptions contain examples of representative ranges, sizes and / or tolerances of some parts. These are provided in an illustrative manner rather than a limiting manner. Unless otherwise stated, all numerals used in the specification and claims to represent the quantity of properties, parameters, conditions, etc. should be understood to be modified by the term "about" or "approximately" in all cases. Therefore, unless otherwise stated, the numerical parameters listed in the following specification and the attached claims are approximate values. Any numerical parameter should at least be interpreted according to the significant figures of the reported numbers and by applying ordinary rounding techniques. The term "about" or "approximately" when used before a numerical representation (such as the size of the measured property) represents an approximate value that may vary (+) or (-) 10%, 5% or 1%.

[0082] As used herein, relative directions and the terms "inwardly" and "outwardly" are relative to the longitudinal axis, wherein inwardly is a direction radially toward the longitudinal axis and outwardly is a direction radially away from the longitudinal axis.

[0083] Relative directions and the terms "distal" and "proximal" are relative to a connector assembly secured to an end of a fluid tube, wherein the distal direction is toward the end of the connector assembly on the end of the fluid tube (e.g., the receiving end of the connector assembly; Figure 1 ), and the proximal direction is toward the beginning of the fluid tube to which the connector assembly is fastened (e.g., Figure 1 ). Relative direction and the terms lateral or laterally are in a plane generally orthogonal to the longitudinal axis.

[0084] Referring generally to the drawings, there is shown a connector assembly (e.g., a line fitting, a push-on connection fitting, etc.) 120. The connector assembly 120 is configured to sealingly engage an end of a fluid pipe (e.g., form a substantially watertight connection with an end of a fluid pipe), such as a copper pipe, a PEX pipe, a CPVC pipe, a PVC pipe, etc. The connector assembly 120 can be used with fluid pipes of different diameters, including fluid pipes with a diameter of less than 0.25 inches to fluid pipes with a diameter of greater than 2 inches.

[0085] Overall reference Figures 1 to 26 , a connector assembly 120 is shown. The connector assembly 120 includes an annular connector body 124, a retainer sleeve (e.g., a sleeve body) 128, a sealing member (e.g., a sealing ring) 132, a protection ring (protection body) 136, a gripping ring (e.g., a gripping body) 140, a barrel (e.g., a barrel body) 146, and a disassembly body (e.g., a disassembly ring) 154.

[0086] Briefly, the connector body 124 includes a latching surface 210 at one end of the connector body 124. The latching surface 210 extends circumferentially around the connector body 124. The retainer sleeve 128 has at least one (in this embodiment, a plurality of) latches 310 extending inwardly at one end of the connector assembly 120. The latches 310 engage the latching surface 210 to connect the retainer sleeve 128 to the connector body 124. In the illustrated embodiment, four equally spaced latches are formed along the retainer sleeve 128; however, different numbers and configurations of latches may be employed, such as two, three, five, or six latches equally or unequally spaced along the retainer sleeve 128, without departing from the scope of the present disclosure.

[0087] As described above and in further detail below, the connector assembly 120 has other components that are retained between, and preferably housed in, the connector body 124 and the retainer sleeve 128. For example, the inwardly stepped protrusion 406 of the protection ring 136 pushes the sealing member 132 toward (e.g., presses against) the inner shoulder 242 of the connector body 124. The grip ring 140 has an annular base 442 having a plurality of protrusions in the form of teeth 444 that extend inwardly and distally toward the connector body 124. The barrel 146 has a tubular wall 448 near the distal end of the barrel 146 and a proximal end 450 of a smaller diameter opposite the tubular wall 448. The tubular wall 448 fits into a notched portion of the connector body 124 having an annular inner shoulder 242 that limits movement in the longitudinal direction along the longitudinal axis 122. The tubular wall 448 extends along the longitudinal axis 122 and surrounds the sealing member 132 , the protection ring 136 , and the grab ring 140 .

[0088] The disassembly body 154 is also located within the retainer sleeve 128 and includes a tubular proximal end (e.g., a free end) 458 that passes through the proximal end 450 of the barrel 146 when the disassembly body 154 extends along the longitudinal axis 122. A stop flange 460 is positioned between the inclined distal surface 456 and the tubular proximal end 458. The stop flange 460 contacts a second inner shoulder 462 of the barrel 146. The inclined distal surface 456 can have a frustoconical profile that is inclined toward the longitudinal axis 122 and inclined toward the connector body 124. The inclined distal surface 456 is also configured to generally conform to the conical shape formed by the inclined teeth 444 of the grip ring 140 and is inclined toward the sealing member 132.

[0089] To further describe the above components in detail, the connector body 124 can be formed of the following materials: a metal material (e.g., brass, such as bismuth brass, naval brass, silicon brass; stainless steel, etc.); a plastic or other polymer material suitable for the intended application (such as polyethylene, PPR or UHMWP), or any combination thereof; a composite material; or any combination thereof. The fluid and pressure conveyed by the fluid tube will determine the appropriate material for the tube and for the connector body 124.

[0090] In some embodiments, the connector body 124 can be a straight connector body 124a or a coupling ( Fig. 20 )、T-type connector body 124b( Fig.21 )、Bend-tube connector body 124c( Fig. 22 ), a blind-end connector body 124d ( FIG. 23A to FIG. 23C) (similar to connector body 124), a connector body configured to receive fluid tubes of different diameters, an angled connector body 124e ( Fig.24 ), multi-wire (or 4-way) connector body 124f ( Fig.25 )、Y-type (Y) connector body 124g ( Fig.26 ), TY (tee-wye) type connector body, other types of connector bodies, or combinations of connector bodies. The connector bodies 124a-124g may have a locking arrangement similar to or the same as the locking surface 210 so as to complement the locking surface 210. FIG. 23A to FIG. 23C As shown, the connector body 124d, which is a blind-end type connector body, has an end wall 204 that closes the fluid passage through the connector body 124d. The end wall 204 forms a tube stop that limits the movement of the fluid tube through the connector body 124d.

[0091] The first end 200 of the connector body 124 is slightly chamfered so that when the retainer sleeve 128 and the connector body 124 move relative to each other, the connector body can resiliently push the resilient latch 310 outward until the latch 310 engages the locking surface 210. It should be understood that the chamfer can be included on any of the connector bodies 124a-124g. An inclined outer shoulder surface 216 adjacent to the locking surface 210 can optionally be provided with a shoulder surface 216 that is inclined inward and toward the first end 200 to align with the latch 310. The shoulder surface 216 can prevent the latch 310 from bending inwardly and can strengthen the latch-lock connection (e.g., the connection between the latch 310 and the locking surface 210), thereby better resisting separation of the connector assembly 120 along the longitudinal axis 122.

[0092] Specific reference Figure 1 , shows an exploded cross-sectional view of the connector assembly 120. The connector assembly 120 extends along the longitudinal axis 122 and is centered on the longitudinal axis 122. When the connector assembly 120 is fully assembled, as shown in FIG. Figures 9 to 13 and Fig.19 As shown, the sealing member 132, the protective ring 136, the grab ring 140, the barrel 146, and the disassembly body 154 are all positioned (e.g., placed) between the retainer sleeve 128 and the connector body 124. The retainer sleeve 128 and the connector body 124 are coupled together so that the remaining parts of the connector assembly 120 (sealing member 132, protective ring 136, grab ring 140, barrel 146, and disassembly body 154) are maintained in a facing relationship with each other (e.g., pressed, compressed, clamped together, etc.), rather than each component being individually coupled together, such as by potting, adhesives, fasteners, latches, etc.

[0093] The sealing member 132 is formed of an elastic material such as rubber, EPDM or other suitable elastomer. The sealing member 132 is shown as an O-ring having a circular cross-section. However, in some embodiments, the sealing member 132 can have a variety of cross-sectional shapes, such as rectangular, oval, pill shape, etc. The inner diameter and outer diameter of the sealing member 132 are selected to fit to the connector body 124 and seal the connector body 124, and form a substantially fluid-tight seal with the fluid tube passing through the inner diameter of the sealing member 132. In some embodiments, the inner shoulder 242 is configured to seal the sealing member 132. As shown in FIG. Fig.14 As shown, the inner shoulder 242 meets the inner surface 240 at a curved corner 243. The radius of the curved corner can be selected to conform to the shape and size of the cross-section of the sealing member 132.

[0094] Now refer to Figure 2 and Figure 3 , a protective ring 136 according to an example embodiment is shown. The protective ring 136 includes a first end 400 (e.g., a proximal end) and a second end 402 (e.g., a distal end) opposite the first end 400. The second end 402 is configured to fit within the first end 200 of the connector body 124 to constrain the sealing member 132 between the inner shoulder 242 and the protective ring 136. The sealing member 132 is allowed to translate axially along the longitudinal axis 122 between the inner shoulder 242 and the protective ring 136. In some embodiments, the sealing member 132 is allowed to translate a distance of 2-5 mm along the longitudinal axis 122. The second end 402 is preferably cylindrical, as is the larger diameter outer body of the annular protective ring 136, so as to form an annular radially inwardly extending protective shoulder 404, which acts as a stopper that contacts the first end 200 of the connector body 124 to limit the relative axial position of the protective ring 136 and the connector body 124 along the longitudinal axis 122.

[0095] In addition, the protective shoulder 404 helps to center the protective ring 136 within the connector body 124. When the protective shoulder 404 is engaged with the first end 200, the second end 402 extends toward the inner shoulder 242 a predetermined distance, thereby limiting the axial movement of the sealing member 132 along the longitudinal axis 122 to 2-5 mm. In other words, the protective ring 136 includes a protrusion 406 extending away from the protective shoulder 404, which helps to position the sealing member 132 in the fluid passage along the longitudinal axis 122. The extension of the protrusion 406 through at least a portion of the connector body 124 helps to support the received fluid tube and helps to achieve a higher pressure rating (e.g., a burst failure rating) of the connector assembly 120. In addition, the protective shoulder 404 reduces the tolerance "stack up" that may affect the positioning of the sealing member 132 and the effectiveness of the sealing engagement between the received fluid tube, the sealing member 132 and the rest of the connector assembly 120. Thus, the protrusion 406 assists during assembly so that alignment requirements can be reduced. In addition, the protective shoulder 404 only extends radially outwardly a short distance and is smaller than the first portion diameter 209 .

[0096] The protection ring 136 includes an inclined surface 410 that is inclined inwardly and toward the second end 402 of the protection ring 136 so as to be generally aligned with the teeth 444 of the grab ring 140. The inclined surface 410 forms a generally frustoconical surface. The axial length of the protection ring 136 and the inclined surface 410 prevents the teeth 444 of the grab ring 140 from contacting and damaging the sealing member 132. The protection ring 136 can be made of a suitable plastic, for example, including but not limited to thermoplastics (such as nylon fibers).

[0097] Now refer to Figure 4 , shows a grab ring 140 according to an example embodiment. The grab ring 140 is formed of a metal such as stainless steel and includes a flat, radially extending base 442 and a plurality of teeth 444 around the longitudinal axis 122. The teeth 444 are equally spaced circumferentially and are sufficient in number to elastically engage with the outer surface of the fluid tube. The teeth 444 bite into the outer surface of the fluid tube to selectively prevent the fluid tube from being removed from the connector assembly 120 along the longitudinal axis 122. When the connector assembly 120 is assembled, the grab ring 140 is retained between the barrel 146 and the protective ring 136. The first end 400 of the protective ring 136 engages the distal side of the base 442, while the first inner shoulder 452 ( Figure 5 ) contacts the proximal side of base 442. When the fluid tube passes through the opening formed by teeth 444, teeth 444 bend radially outward and toward inclined surface 410. One or both of the inner diameter of protection ring 136 and the relative angles of teeth 444 can limit the maximum diameter of the fluid tube that can be inserted through grip ring 140 and protection ring 136.

[0098] Now refer to Figure 5 and Figure 6 , shows a barrel 146 according to an example embodiment. The barrel 146 includes a second inner shoulder 462 extending radially inwardly from the first inner shoulder 452. The first inner shoulder 452 forms an axially aligned face against which the stop flange 460 of the disassembly body 154 abuts to limit axial movement of the disassembly body 154 relative to the barrel 146 in one axial direction. The tubular proximal end 458 ( Figure 7 ) is inserted from the distal end of the barrel 146 until the stop flange 460 contacts the second inner shoulder 462 on the barrel 146. Thus, the barrel 146 limits the movement of the disassembly body 154 and / or the gripping ring 140 along the longitudinal axis 122 (in the proximal direction). The disassembly body 154 can move in the distal direction along the longitudinal axis 122 and can cause the teeth 444 to expand outwardly so that the teeth 444 are disengaged from the fluid tube previously engaged by the teeth 444. Thus, a force applied in the distal direction on the proximal end 458 of the disassembly body 154 can cause the teeth 444 to disengage from the fluid tube and allow the fluid tube to be removed from the connector assembly 120. The barrel 146 can be formed of a suitable strong polymer that is compatible with the fluid carried in the fluid tube. In some embodiments, the barrel 146 is formed of POM (polyoxymethylene).

[0099] Now refer to Figure 7 and Figure 8 , shows a disassembly body 154 according to an example embodiment. When the connector assembly 120 is assembled, the disassembly body 154 is positioned within the barrel 146 and is configured to be positioned within the barrel 146 while moving axially along the longitudinal axis 122. The inclined distal surface 456 of the disassembly body 154 is proximal to the tooth 444, and the inclined surface 410 on the protective ring 136 is distal to the tooth 444. The tooth 444 is disposed between the inclined distal surface 456 and the inclined surface 410. Advantageously, the inclined distal surface 456 on the disassembly body 154 is configured to engage with the base of the tooth 444 adjacent to the base 442. The disassembly body 154 can be formed of POM.

[0100] To further describe the structure of the connector assembly 120 in detail, the protective ring 136 advantageously has an engagement member 477 ( Figure 2 ), and the engagement member 477 is configured to cooperate with another engagement feature on the barrel 146. The illustrated configuration of the engagement member 477 includes a slightly outward protrusion, preferably a slightly convex circumferential ring with an inclined leading edge and / or trailing edge. When the connector assembly 120 is assembled, the engagement member 477 is located in a circumferential recess 479 ( Figure 5) and is configured to fit into the recess. Advantageously, when the engagement member 477 on the protection ring 136 engages with the recess 479 on the barrel 146, the protection ring 136 and the barrel 146 are held together to secure the grab ring 140 between the first inner shoulder 452 on the barrel 146 and the first end 400 of the protection ring 136. In addition, the removal body 154 is preferably already in place so that the stop flange 460 engages with the second inner shoulder 462 of the barrel 146. The snap connection of the engagement member 477 and the recess 479 restricts the removal body 154 from being removed from the barrel 146. The removal body 154 can move axially between the second inner shoulder 462 and the grab ring 140. The barrel 146 and the protection ring 136 can thus form a snap-fit ​​subassembly, which restricts the movement of the removal body 154 and the grab ring 140 so that these components can move together as a unit.

[0101] The diameter of the tubular wall 448 is selected so that the tubular wall 448 engages the connector body 124. When the barrel 146 engages the connector body 124, the grip ring 140 is coupled between the protection ring 136 and the first inner shoulder 452 on the barrel 146, and the removal body 154 is positioned so that the inclined distal surface 456 does not push the teeth 444 radially outward and away from the longitudinal axis 122. Advantageously, the protection ring 136 extends into the connector body 124 and, as described above, allows the sealing member 132 to move axially about 2-5 mm along the longitudinal axis 122 before contacting the protection ring 136 or the inner shoulder 242 on the connector body 124. When the distal end of the fluid tube contacts the sealing member 132, the axial movement of the sealing member 132 is insufficient to allow the sealing member 132 to skew or tilt enough to become misaligned.

[0102] Now refer to Fig. 9 , shows a side view of connector assembly 120 according to an example embodiment. When retainer sleeve 128 is coupled to connector body 124, retainer sleeve 128 covers a portion of connector body 124. A portion of barrel 146 extends axially out of the proximal end of retainer sleeve 128, and a portion of disassembly body 154 extends axially out of the proximal ends of both retainer sleeve 128 and barrel 146. In some embodiments, connector assembly 120 does not include end wall 204, and fluid is configured to flow through both ends of connector assembly 120.

[0103] Now refer to Fig.10 , shows a distal end view of a connector assembly 120 according to another example embodiment. The connector body 124 may include an end wall 204 so that the connector body 124 has a closed end that cuts off a fluid passage through the connector assembly 120 along the longitudinal axis 122. In some embodiments, as Figure 1As shown, the connector body 124 has a central bore 205 that allows a fluid passage to extend all the way through the connector body 124 .

[0104] Now refer to Fig.11 , shows a proximal end view of a connector assembly 120 according to an example embodiment. The proximal end of the connector assembly 120 is configured to receive a fluid tube.

[0105] Now refer to Fig.12 and Fig.13 , a side cross-sectional view of a connector assembly 120 according to an example embodiment is shown. After the connector assembly 120 is assembled, a fluid tube can then be inserted through the open end of the connector assembly 120. The fluid tube is inserted through the retainer sleeve 128, through the disassembly body 154 and through the tubular wall 448 of the barrel 146 until the distal end of the fluid tube passes through the grab ring 140, the protective ring 136 and the sealing member 132. In some embodiments, the fluid tube contacts a hard stop, which prevents relative axial movement of the fluid tube along the longitudinal axis 122. In some embodiments, the connector assembly 120 includes a tube liner 480 retained within the connector assembly 120. The tube liner 480 helps to support the inner wall of the fluid tube configured to be received by the connector assembly 120. In this regard, the tube liner 480 will be located within the disassembly body 154 and configured to receive the fluid tube.

[0106] The teeth 444 prevent the fluid tube from being pulled out of the proximal end of the connector assembly 120. The outer diameter of the fluid tube is greater than the inner diameter of the sealing member 132 to form a substantially fluid-tight seal. Depending on the amount of fluid sealing or leakage desired or allowed, the interference fit between the sealing member 132 and the fluid tube can vary. The sealing member 132 is advantageously allowed to slide axially a distance of about 2-5 mm in the cylindrical recessed portion along the longitudinal axis 122 terminating at the inner shoulder 242. Alternatively, in some embodiments, the sealing member 132 can be pressed against the inner shoulder 242 by the second end 402 of the protective ring 136. That is, the protrusion 406 can, for example, extend to a position that compresses the sealing member 132. This can increase the integrity of the sealing engagement of the sealing member 132.

[0107] In addition, to prevent the fluid tube from accidentally disengaging from the connector assembly 120, the axial length of the tubular proximal end 458 of the disassembly body 154 is selected to terminate at the proximal end of the retainer sleeve 128 and / or the barrel 146. Therefore, the sleeve opening 368, the proximal end of the disassembly body 154, the tubular proximal end 458, and the proximal end 450 of the barrel 146 are in the same general plane. Advantageously, the disassembly body 154 is located about 1 mm or less slightly distal of the plane passing through the proximal end 458 and / or the proximal end 450. The barrel 146 contacts the connector body 124 and can remain fixed relative to the disassembly body 154, which is configured to move axially toward the connector body 124. To avoid accidental contact between the proximal end of the disassembly body 154 and the gripping ring 140, which would reduce the gripping force of the gripping ring 140 on the fluid tube, the proximal end of the disassembly body 154 may be flush with or slightly distal to both the first end 300 of the retainer sleeve 128 and the proximal end of the barrel 146, so that when a force is applied to the barrel 146 or the connector body 124 at least on the disassembly body 154, the connector body 124 and the barrel 146 resist axial movement of the disassembly body 154. In other words, the disassembly body 154 is positioned so that an external force applied to the barrel 146 from at least the disassembly body 154 will not allow the disassembly body 154 to move to a position that disengages the teeth 444 from the fluid tube. On this basis, in order to release the fluid tube, the connector assembly 120 may require a specific tool to engage the disassembly body 154 alone without engaging other components of the connector assembly 120.

[0108] In order to remove the fluid tube from the connector assembly 120, the disassembly body 154 is pushed axially along the longitudinal axis 122 toward the distal end of the connector assembly 120 (such as using a specific tool) and toward the connector body 124, so that the inclined surface 410 of the disassembly body 154 engages with the teeth 444 and expands the teeth 444 outward, so that the teeth 444 disengage from the outer surface of the fluid tube and allow the fluid tube to be removed along the longitudinal axis 122. Therefore, the connector assembly 120 is configured so that a portion of the connector assembly 120 surrounds and prevents lateral movement of the fluid tube relative to the connector assembly 120, and prevents lateral removal of the fluid tube from the connector assembly 120.

[0109] Advantageously, the connector assembly 120 allows components (e.g., fluid pipes) to be arranged and snapped together for relatively convenient use. The connector assembly 120 does not require manual deformation of any component to produce a substantially watertight engagement with the fluid pipe. The connector assembly 120 only needs to be placed on the end of the fluid pipe, and either or both of the connector assembly 120 and the fluid pipe are moved axially together to connect the connector assembly 120 and the fluid pipe so that the sealing member 132 provides a fluid-tight connection, while the connector body 124 (or 124a-124g) allows the fluid pipe to be used for a variety of fluid connections. If the user wishes to disconnect the components, the disassembly body 154 can be used and manually pressed to disengage the disassembly body 154 from the fluid pipe, but preferably a tool is used to engage the proximal end of the disassembly body 154 and axially move the disassembly body 154 along the longitudinal axis 122 to release the grip ring 140 and disengage the fluid pipe. If it is desired to open the connector assembly 120 , a tool may be inserted into each latch opening 314 in the sleeve sidewall 303 to force each of the plurality of latches 310 out of engagement with the locking surface 210 , thereby disassembling the connector assembly 120 .

[0110] Beneficially, the latch opening 314 does not allow for manual access by a user's fingers to release the latch members 311 from the latch surface 210. The use of mating two or more latches and (one or more) latches and the tight fit of the retainer sleeve 128 around the enclosed component make it impractical to sequentially release the plurality of latches 310 from the latch surface 210. Thus, preferably, the plurality of latches 310 cannot be disengaged from the latch surface 210 without a specialized tool or without permanently deforming at least one of the retainer sleeve 128 and the connector body 124. Thus, the coupling between the plurality of latches 310 and the latch surface 210 is not a releasable (e.g., removable, selectively releasable) connection and may require deformation or breakage of the retainer sleeve 128 or the connector body 124, which may result in a visible record (e.g., an indicator) that the plurality of latches 310 are disengaged. In some embodiments, plurality of latches 310 and locking surface 210 form a permanent connection between retainer sleeve 128 and connector body 124 that cannot be removed without destroying connector assembly 120 .

[0111] As described above, the connector assembly 120 can be formed of one or more materials. For high strength or high pressure applications, it is appropriate to consider that all components are made of suitable metals except the sealing member 132. The material used for the fluid pipe will vary depending on the intended use and may include metal pipes (e.g., copper, brass, iron), hard plastic pipes (e.g., for pipelines), flexible plastic pipes or flexible braided metal pipes, and braided plastics or other braided materials.

[0112] Now refer to Fig.14 , shows a side cross-sectional view of a connector body 124 according to an example embodiment. The connector body 124 includes a generally annular body having a first end 200 (e.g., distal end) and a second end 202 (e.g., proximal end) opposite the first end 200. The first end 200 is configured to receive a fluid tube, such as a copper tube, etc. Fig.14 , the second end 202 is open such that fluid is configured to flow through both ends (e.g., the first end 200 and the second end 202) of the connector body 124. The second end 202 can be fluidly coupled to a pipe fitting having a plurality of connector assemblies 120. For example, a T-fitting can include three connector assemblies 120. Figure 20 to Figure 26 Other example accessories are shown. In some embodiments, FIG. 23A to FIG. 23C As shown, the second end 202 includes an end wall 204 that is fluid tight and provides a hard stop for the fluid tube.

[0113] The connector body 124 also includes a first portion (e.g., a flange) 206 that extends radially away from the annular body near the first end 200. The first portion 206 extends circumferentially around the longitudinal axis 122. The first portion 206 includes a first engagement surface 208 and a locking surface 210. The first engagement surface 208 is the outermost radial surface of the first portion 206. In some embodiments, the first engagement surface 208 is concentric with the longitudinal axis 122. The first engagement surface 208 defines a first portion diameter 209 (e.g., a first diameter). The locking surface 210 is connected to the first engagement surface 208, extends circumferentially around the longitudinal axis 122, and extends approximately perpendicular to the longitudinal axis 122.

[0114] The connector assembly 120 also includes an interference portion (or interference feature) 212 positioned along the connector body 124. For example, Fig.14 and Fig.15 As shown, the interference portion 212 extends circumferentially around the connector body 124 at a position between the first end 200 and the second end 202. In some embodiments, the interference portion 212 extends circumferentially around the connector body 124 at a position between the first portion 206 and the second end 202. In some embodiments, the interference portion 212 is located approximately midway between the first end 200 and the second end 202. In some embodiments, the interference portion 212 is positioned closer to the first end 200 relative to the second end 202. The interference portion 212 includes a second engagement surface 214. The second engagement surface 214 is an outermost radial surface of the interference portion 212. In some embodiments, the second engagement surface 214 is concentric with the longitudinal axis 122 and the first engagement surface 208. The second engagement surface 214 defines a second portion diameter 218 (e.g., a second diameter).

[0115] The connector assembly 120 also includes a shoulder surface 216. The shoulder surface 216 is connected to the second engagement surface 214 and extends circumferentially around the longitudinal axis 122. The shoulder surface 216 defines a frustoconical profile that tapers to a larger diameter as the shoulder surface 216 extends from the first portion 206 to the interference portion 212. The shoulder surface 216 acts as a ramp to guide a portion of the retainer sleeve 128 to engage the second engagement surface 214 during assembly. In some embodiments, the second portion diameter 218 is larger than the first portion diameter 209. In some embodiments, the second portion diameter 218 is larger than the first portion diameter 209 by an amount between about 0.3 mm (millimeters) and about 0.5 mm, inclusive.

[0116] During assembly of the connector assembly 120, the interference portion 212 can be disposed between the retainer sleeve 128 and the connector body 124. In some embodiments, the interference portion 212 is coupled to the connector body 124. In the illustrated embodiment, as shown in FIG. Fig.14 and Fig.15 As shown, the interference portion 212 and the shoulder surface 216 are integrally formed with the connector body 124. As used herein, two or more elements are "integrally formed" with each other when they are formed and joined together as part of a single manufacturing step to form a single piece or unitary structure that cannot be disassembled without at least partially destroying the entire component. For example, the interference portion 212 and the shoulder surface 216 can be formed in the connector body 124 by turning, milling, or other suitable cutting or machining processes, so that the interference portion 212 and the connector body 124 are integrally formed. In other examples, the connector body 124 can be molded or otherwise formed to include the interference portion 212 and the shoulder surface 216. In additional or alternative embodiments, the interference portion 212 can be part of or coupled to the retainer sleeve 128. For example, the interference portion 212 may include a plurality of ribs, protrusions, etc., or a collection or group thereof: they are formed along or connected to the inner surface of the retainer sleeve 128 and are constructed to engage the connector body 124 to facilitate an interference fit between the connector body 124 and the retainer sleeve 128.

[0117] In some embodiments, the interference portion 212 can be formed separately from the connector body 124 and subsequently coupled to the connector body 124. For example, the interference portion 212 can include an annular ring, such as a circlip or other movable, removable portion, that can be selectively disposed around the connector body 124. Additionally, the shoulder surface 216 can be formed separately from the connector body 124 and subsequently coupled to the connector body 124. For example, during assembly of the connector assembly 120, the shoulder surface 216 can be disposed between the retainer sleeve 128 and the connector body 124. In some embodiments, the shoulder surface 216 is coupled to the connector body 124. In some embodiments, the shoulder surface 216 can slide between the first portion 206 and the interference portion 212.

[0118] Reference Fig.15 , the interference portion 212 may include a flange or other protrusion (e.g., a second flange 213) extending radially away from the connector body 124 at a position between the first portion 206 and the second end 202. In some embodiments, the second flange 213 is located approximately midway between the first end 200 and the second end 202. In some embodiments, the second flange 213 is located closer to the first end 200 than the second end 202. The second flange 213 includes a second engagement surface 214 and a shoulder surface 216. The second engagement surface 214 is the outermost radial surface of the second flange 213.

[0119] Located between the first portion 206 and the interference portion 212 is a connector body groove 230 (e.g., a channel or other recessed area). The connector body groove 230 includes a groove surface 232 extending circumferentially around the longitudinal axis 122. In some embodiments, the groove surface 232 is generally concentric and parallel to the longitudinal axis 122. In some embodiments, the shoulder surface 216 extends between the first portion 206 and the interference portion 212, such that the shoulder surface 216 interfaces with the locking surface 210.

[0120] Refer again Fig.14 , an inner shoulder 242 is shown extending radially inward from the inner surface 240 of the connector body 124. The inner shoulder 242 is configured to abut with the sealing member 132 when the fluid tube extends into the connector assembly 120 to form a substantially watertight seal between the connector body 124, the sealing member 132 and the fluid tube.

[0121] Now refer to Fig.16, a cross-sectional view of the retainer sleeve 128 is shown. The retainer sleeve 128 includes a generally annular body having a first end 300 (e.g., a proximal end) and a second end 302 (e.g., a distal end) opposite the first end 300. The first end 300 is configured to receive a fluid tube, such as a copper tube. The second end 302 is configured to receive the connector body 124 and cover at least a portion of the connector body 124.

[0122] The retainer sleeve 128 also includes a sleeve opening 368 that extends into the first end 300 and extends along the longitudinal axis 122. The size of the sleeve opening 368 allows the proximal end 450 of the barrel 146 to pass through. Advantageously, the fit between the sleeve opening 368 and the proximal end 450 of the barrel 146 is tight (e.g., a sliding fit) so that the retainer sleeve 128 radially supports the proximal end 450 of the barrel 146, which in turn supports the proximal end 458 of the disassembly body 154, which in turn supports the fluid tube passing through the disassembly body 154. The first end 300 of the retainer sleeve 128 includes a circular reduced diameter portion near the first end 300, shown as a sleeve chamfer 384. The sleeve chamfer 384 increases the radial and axial stiffness of the retainer sleeve 128 and allows for suitable clearance for components housed within the retainer sleeve 128. For example, first end 300 of retainer sleeve 128 is shown as including a straight portion extending axially away from sleeve chamfer 384, which increases the strength of retainer sleeve 128 and prevents (e.g., inhibits) unrolling of retainer sleeve 128. The outer periphery of retainer sleeve 128 preferably conforms to the outer shape of the internal components of retainer sleeve 128, including the portion of connector body 124 surrounded by retainer sleeve 128. Advantageously, second end 302 of retainer sleeve 128 overlaps a portion of connector body 124. As described above, the remainder of connector body 124 will vary depending on whether connector body 124 is an in-line connector, elbow connector, T-connector, Y-connector, multi-tube connector, blind-end connector, or other type of connector.

[0123] The retainer sleeve 128 also includes a sleeve sidewall 303 having an inner sleeve surface 304 extending between the first end 300 and the second end 302. The inner sleeve surface 304 defines a sleeve diameter 308 (e.g., a third diameter). In some embodiments, the sleeve diameter 308 is greater than the first portion diameter 209 and less than the second portion diameter 218. In some embodiments, the sleeve diameter 308 is less than both the first portion diameter 209 and the second portion diameter 218.

[0124] The retainer sleeve 128 also includes a plurality of latches 310, which include at least one latch member 311. Each of the plurality of latches 310 extends radially inward from the inner sleeve surface 304 toward the longitudinal axis 122. Each of the plurality of latches 310 includes a resiliently flexible protrusion in the form of a rectangular tab. A latch opening 314 is positioned at the proximal end of each of the plurality of latches 310 and extends through the sleeve sidewall 303. In some embodiments, each of the plurality of latches 310 includes an elongated member that is resiliently urged in a direction toward the longitudinal axis 122 and is configured to engage with the locking surface 210 when the retainer sleeve 128 is coupled to the connector body 124. Each of the plurality of latches 310 is shown in a release position 313. In the release position 313, the plurality of latches 310 extend radially inward from the inner sleeve surface 304 at a first non-zero angle relative to the longitudinal axis 122. In some embodiments, the first non-zero angle can be greater than 15 degrees, such as between 15-30 degrees (inclusive), or between 30-45 degrees (inclusive). In some embodiments, the first non-zero angle is a non-zero angle of 5 degrees or less. Thus, each of the plurality of latches 310 extends transversely toward the longitudinal axis 122 so as to extend into the connector body recess 230 and engage the locking surface 210.

[0125] Each of the plurality of latches 310 is cut out in the sleeve sidewall 303 so that each of the plurality of latches 310 is integrally formed with the retainer sleeve 128. In some embodiments, each of the plurality of latches 310 comprises a rectangular profile. In some embodiments, each of the plurality of latches 310 comprises a trapezoidal profile. In some embodiments, each of the plurality of latches 310 comprises a profile with rounded edges. After at least one of the plurality of latches 310 is formed with the retainer sleeve 128, the at least one latch member 311 is bent radially inwardly toward the longitudinal axis 122. The latch opening 314 in the sidewall 303 defines a latch end 312 (e.g., a free end, a proximal end, etc.) of the latch member 311. Two parallel cuts 316 substantially parallel to the longitudinal axis 122 extend into the sleeve sidewall 303 and extend toward the latch opening 314 to define the remaining two sides of the substantially rectangular plate forming the latch member 311. Because sleeve sidewall 303 is curved, latch end 312 of latch member 311 is slightly curved with the same overall curvature as sleeve sidewall 303. When retainer sleeve 128 is coupled to connector body 124, the curvature of latch member 311 may approximate the curvature of groove surface 232. The curvature (e.g., radius) of latch member 311 provides reinforcement to latch member 311 and increases the rupture failure pressure of connector assembly 120.

[0126] The retainer sleeve 128 also includes an end or region 326 proximate the second end 302. The end 326 extends between the second end 302 and the base of the plurality of latches 310. The curved surface 328 is Fig.16 and Fig.17 326 is indicated with dashed lines to illustrate the approximate location of the bend of the plurality of latches 310 (e.g., the base of the plurality of latches 310). When the retainer sleeve 128 is coupled to the connector body 124, the end portion 326 engages the second engagement surface 214 of the interference portion 212. In some embodiments, such as when the sleeve diameter 308 is less than the second portion diameter 218, the end portion 326 expands to the second portion diameter 218 such that an interference fit is formed between the retainer sleeve 128 and the connector body 124. As a result, the end portion 326 is at least one of plastically or elastically deformed to correspond to the second portion diameter 218.

[0127] For example, sleeve diameter 308 may be approximately 0.001 to approximately 0.005 inches (approximately between approximately 0.0254 to approximately 0.127 millimeters) smaller than second portion diameter 218. When retainer sleeve 128 is pressed onto connector body 124, second end 302 of retainer sleeve 128 engages shoulder surface 216, which helps expand end 326 to second portion diameter 218.

[0128] In some embodiments, the sleeve diameter 308 can be about 0.008 to about 0.02 inches (e.g., about 0.2 to about 0.5 millimeters) smaller than the second portion diameter 218. As will be appreciated by one of ordinary skill in the art, interference fits having the aforementioned tolerance ranges are typically tighter than a standard and acceptable interference fit. As used herein, the terms "enhanced interference fit" and "improved interference fit" are used to refer to an interference fit that is tighter than an acceptable or typical interference fit (e.g., a shaft having a diameter that is larger than a conventionally acceptable diameter for a given size of hole). As will be appreciated by one of ordinary skill in the art, forming an interference fit between two components outside of an acceptable tolerance range may result in a fit that is either too loose (e.g., a partial interference fit that compromises the rigidity of the fit under load) or too tight (e.g., causing unexpected damage to the components during assembly and / or use, such as causing a new hole to be reamed out of the shaft, a shaft to bend / break, or a hole to rupture).

[0129] Now refer to Fig.18 and Fig.19 , showing the retainer sleeve 128 before and after being coupled to the connector body 124. Fig.18, the plurality of latches 310 are in a released (e.g., initial, first, rest, unlocked, etc.) position 313. In the released position 313, the plurality of latches 310 may extend at a first non-zero angle relative to the longitudinal axis 122. When the retainer sleeve 128 is coupled to the connector body 124, the thin sidewall 303 of the retainer sleeve 128 allows the end 326 to flare radially outward to the second portion diameter 218 to form a flared portion 327.

[0130] Now refer to Fig.19 , the retainer sleeve 128 is shown coupled to the connector body 124, wherein the plurality of latches 310 are shown in a locked (e.g., second, engaged, levered, etc.) position 315. In the locked position 315, the plurality of latches 310 are in a position, orientation, configuration, etc. (i.e., a second position, orientation, configuration, etc.) that is different from the position, orientation, configuration, etc. of the latches in an initial, released position 313 (i.e., a first position, orientation, configuration, etc.), wherein the second position, orientation, configuration, etc. of the plurality of latches 310 provides improved, enhanced, etc. engagement between the plurality of latches 310 and the connector body 124. For example, in the locked position 315, the free ends 312 of the latch members 311 may be spaced further from the inner sleeve surface 304 of the retainer sleeve 128 than when the latch members 311 are in the initial, released position 313. That is, in the locked position 315, the distance between the free end 312 of the latch member 311 and the inner sleeve surface 304 of the retainer sleeve 128 is greater than the distance between the free end 312 of the latch member 311 and the inner sleeve surface 304 of the retainer sleeve 128 in the initial release position 313. Therefore, the plurality of latches 310 improve / enhance engagement with the locking surface 210 on the connector body 124 (e.g., the increased distance between the free end 312 of the latch member 311 and the retainer sleeve 128 increases the area or portion of engagement between the latch member 311 and the locking surface 210 (or the groove surface 232)), reduce the possibility of partial or discontinuous engagement between the plurality of latches 310 and the locking surface 210 (or the groove surface 232), or increase the force of engagement between the plurality of latches 310 and the locking surface 210 (or the groove surface 232). Additionally, in the locked position 315 , the plurality of latches 310 may extend radially inwardly at a second non-zero angle relative to the longitudinal axis 122 that is greater than the first non-zero angle of the plurality of latches 310 in the initial released position 313 .

[0131] In some embodiments, the plurality of latches 310 are biased radially outwardly such that the plurality of latches 310 are more aligned with the sidewall 303 in the locked position 315 than in the released position 313. In some embodiments, the flared portion 327 of the end portion 326 is substantially retained within the end portion 326 (e.g., between the curved plane 328 and the second end 302). In some embodiments, the enhanced (e.g., improved, extreme, etc.) interference fit creates (e.g., imparts) a slight taper in the retainer sleeve 128 that extends beyond the curved plane 328 and toward the first end 300 when the retainer sleeve 128 is coupled to the connector body 124. In some embodiments, the end portion 326 is flared radially outwardly at the second end 302 such that the diameter of the second end 302 is greater than the median diameter of the retainer sleeve 128. In some embodiments, the flared portion 327 extends radially away from the longitudinal axis 122 at a non-zero angle. When retainer sleeve 128 is coupled to connector body 124 , second end 302 defines a third diameter 329 that is greater than second portion diameter 218 .

[0132] The flaring of the end 326 causes deformation (e.g., prying, bending, biasing, etc.) of the plurality of latches 310 toward the longitudinal axis 122. In other words, when the end 326 engages the interference portion 212, each of the plurality of latches 310 transitions from the release position 313 to the locked position 315. In the release position 313, each of the plurality of latches 310 extends radially inward from the inner sleeve surface 304 at a first non-zero angle. In the locked position 315, each of the plurality of latches 310 is biased radially inward toward the connector body 124 to improve engagement between the plurality of latches 310 and the connector body groove 230. In some embodiments, the plurality of latches 310 bite into (e.g., sink into) the lock surface 210 (or groove surface 232) to improve the connection between the retainer sleeve 128 and the connector body 124.

[0133] The transition of the plurality of latches 310 from the release position 313 to the locked position 315 when the end 326 is engaged with the interference portion 212 helps increase the failure strength of the connector assembly 120. In other words, when the plurality of latches 310 is in the locked position 315, the environmental burst strength is increased (e.g., at least in part due to the increased engagement of the plurality of latches 310), and the failure point may be a failure between the fluid tube and the teeth 444, rather than a failure at the engagement of the retainer sleeve 128 with the connector body 124.

[0134] When retainer sleeve 128 is coupled to connector body 124, interference portion 212 engages end portion 326 and causes second end 302 of retainer sleeve 128 to flare outwardly relative to second portion diameter 218. Flaring of end portion 326 causes plurality of latches 310 to deform (e.g., to expand around second portion diameter 218). Fig.19 The curved flat surface 328 shown is rotated or otherwise pried up) and engaged with the locking surface 210 (or the groove surface 232). The prying action of the plurality of latches 310 can improve the engagement (e.g., degree of engagement, engagement force, etc.) between the plurality of latches 310 and the connector body 124. In some embodiments, the prying action of the plurality of latches 310 improves the fracture failure strength of the connector assembly 120. In particular, the retainer sleeve 128 and the plurality of latches 310 together provide sufficient strength for the connector assembly 120 to reduce the possibility of fracture-related failures.

[0135] In some embodiments, the environmental burst strength of the connector assembly 120 is 1,800 pounds per square inch (psi) or greater. In some embodiments, the environmental burst strength is between 1,000 psi and 2,100 psi, inclusive. For example, the environmental burst strength can be between 1,100 psi and 2,100 psi, inclusive; between 1,200 psi and 2,100 psi, inclusive; between 1,300 psi and 2,100 psi, inclusive; between 1,400 psi and 2,100 psi, inclusive; between 1,500 psi and 2,100 psi, inclusive; between 1,600 psi and 2,100 psi, inclusive; between 1,700 psi and 2,100 psi, inclusive; and between 1,800 psi and 2,100 psi, inclusive, and so on.

[0136] The flaring of the end portion 326 also serves to facilitate centering of the retainer sleeve 128 about the connector body 124 during assembly. The flared portion 327 may extend radially outwardly equally at all points around the circumference of the end portion 326 so that the retainer sleeve 128 is centered relative to the interference portion 212. In some embodiments, after the retainer sleeve 128 is coupled to the connector body 124, the plurality of latches 310 are pressed into the connector body 124 by a separate process. For example, the retainer sleeve 128, and in particular the plurality of latches 310 and the end portion 326, may be bonded to the connector body 124 (e.g., pressed into the connector body 124, such that the retainer sleeve 128 is plastically deformed, such as by rolling, knurling, individually pressing each of the plurality of latches 310 into the connector body 124, etc.). In some embodiments, when the retainer sleeve 128 is coupled to the connector body 124, the enhanced interference fit between the connector body 124 and the retainer sleeve 128 prevents the retainer sleeve 128 from rotating relative to the connector body 124 about the longitudinal axis 122. The retainer sleeve 128 can be formed of stainless steel and is advantageously draw-formed by successive drawing steps, in which the latch openings 314 and the plurality of latches 310 are stamped out of the retainer sleeve 128 in a subsequent drawing stage. The plurality of latches 310 can be formed by a stamping or die-casting process. The stamping or die-casting process produces cut edges in the retainer sleeve 128. In some examples, the plurality of latches 310 can be stamped independently such that the retainer sleeve 128 is rotated 90 degrees between each stamping, thereby manufacturing the plurality of latches 310 in four steps. In some examples, a total of four latches 310 are formed in retainer sleeve 128 , and two of the four latches 310 may be simultaneously stamped out in retainer sleeve 128 180 degrees apart.

[0137] Figure 20 to Figure 22 , FIG. 23A to FIG. 23C as well as Figure 24 to Figure 26 The various connector assemblies shown in the drawings may have one or more components of the connector assembly 120 described above, and although certain component numbers are shown in the drawings, the description of these components will not be repeated. In particular, it should be understood that the connector bodies 124a-124g can be used in place of the connector body 124, and the remaining portions of the connector assembly 120 (i.e., the retainer sleeve 128, the sealing member 132, the protective ring 136, the grab ring 140, the barrel 146 and the removal body 154) are used to form a corresponding connector. Figure 20 to Figure 22 , FIG. 23A to FIG. 23C as well as Figure 24 to Figure 26As shown, multiple connectors are used at each end of the connector body 124a-124g to form a connector assembly. In the configuration where the fluid passage extends through the connector body 124a-124c, 124e-124g, the tube stop can take the form of an internal shoulder on the connector body 124a-124c, 124e-124g, surrounding the flow passage and preferably forming an annular surface.

[0138] Overall reference Figures 27 to 33 , a method 500 of assembling a connector assembly 120 is shown according to an example embodiment. At step 502, a connector body, such as connector body 124, is obtained. The connector body is arranged along an axis, such as longitudinal axis 122. In some embodiments, the connector body includes a fluid channel (e.g., a flow path) extending at least partially through the connector body. The connector body may also include an interference portion, such as interference portion 212. In some embodiments, obtaining the connector body includes forming the connector body. The connector body may be formed with or without the interference portion. In some embodiments, the obtained connector body is Fig.14 and Fig.15 The connector body 124 is provided.

[0139] At step 504, a retainer sleeve, such as retainer sleeve 128, is obtained. The retainer sleeve is configured to receive at least a portion of the connector body and extends circumferentially around the axis. In some embodiments, the retainer sleeve is provided with a plurality of latches. The retainer sleeve is configured to receive at least a portion of the connector body and the retainer sleeve is configured to extend circumferentially around the fluid passage. In some embodiments, providing the retainer sleeve includes forming the retainer sleeve. In some embodiments, the retainer sleeve obtained is based on Fig.16 and Fig.17 The retainer sleeve 128 is provided.

[0140] At step 506, the connector body is positioned on a fixture (such as fixture 530). Fig.28 As shown, the connector body is positioned on the fixture such that the first end 200 of the connector body is closer to the press 532 than the second end 202 of the connector body.

[0141] At step 508, a plurality of components are positioned between the retainer sleeve and the connector body. In some embodiments, the sealing member 132, the protective ring 136, the grip ring 140, the disassembly body 154, and the barrel 146 are positioned between the connector body 124 and the retainer sleeve 128. For example, Fig.28As shown, the connector body can be positioned on the fixture 530, and the sealing member 132, the protective ring 136, the grab ring 140, the disassembly body 154, and the barrel 146 are positioned on (e.g., positioned in) the connector body 124. More specifically, as described above, the disassembly body 154 and the grab ring 140 are accommodated between the barrel 146 and the protective ring 136 by the engagement member 477 and the circumferential recess 479 to form a subassembly. Separately, the sealing member 132 is placed in the connector body 124, and the above-mentioned subassembly is then inserted into the connector body 124 so that the second end 402 of the protective ring 136 enters the cylindrical recessed portion of the connector body 124 until the protective shoulder 404 contacts the first end of the connector body 124. In this way, the sealing member 132 is positioned between the inner shoulder 242 of the connector body 124 and the second end 402 of the protective ring 136.

[0142] At step 510, an interference portion, such as interference portion 212, is disposed circumferentially around an axis. In some embodiments, the interference portion is disposed circumferentially around a fluid passage. In some embodiments, the interference portion is coupled to a connector body. In some embodiments, the interference portion is formed in the connector body before or after obtaining the connector body.

[0143] At step 512, the retainer sleeve is positioned over the inner component such that the inner component is disposed between the retainer sleeve and the connector body. Fig.29 , the retainer sleeve is shown positioned on the barrel 146.

[0144] At step 514, the retainer sleeve is pressed onto the connector body and around the connector body using a press 532. Fig.30 As shown, the press 532 is moved downwardly in a direction toward the second end 202 of the connector body.

[0145] In step 516, if Fig.31 As shown, the retainer sleeve is moved (e.g., pressed) to place the interference portion between the connector body and the retainer sleeve. In some embodiments, the retainer sleeve is pressed around the interference portion so that the interference portion engages with the portion of the inner sleeve surface near the first sleeve end and deforms and expands the portion of the inner sleeve surface near the first sleeve end in diameter to a coupling diameter greater than the inner sleeve diameter. In some embodiments, the press 532 is operated to push (e.g., press) the retainer sleeve 128 onto the connector body 124.

[0146] In some embodiments, the retainer sleeve is pressed around both the connector body and the interference portion to form an interference fit between the retainer sleeve and the interference portion, thereby preventing the retainer sleeve from rotating about the axis relative to the connector body. In some embodiments, rotation about the fluid passage is prevented by the interference fit between the retainer sleeve and the connector body.

[0147] At step 518, the plurality of latches are engaged with the locking surface of the connector body. More specifically, the retainer sleeve 128 is pressed onto the connector body 124 until each of the plurality of latches 310 engages with the locking surface 210 to lock (e.g., couple) the retainer sleeve 128 to the connector body 124 and form the connector assembly 120. At the same time, the end 326 of the retainer sleeve 128 engages with the interference portion 212 and forms an interference fit, thereby preventing the retainer sleeve 128 from rotating relative to the connector body 124. In some embodiments, such as Fig.31 As shown, the interference portion is disposed between the retainer sleeve and the connector body, typically at or about the same time as the plurality of latches engage the locking surface of the connector body. In addition, the plurality of latches 310 are moved from an initial release position 313 to a locked position 315, for example, to improve engagement between the plurality of latches 310 and the locking surface 210. When retained by the locking surface 210, the plurality of latches 310 extend in a transverse direction of the longitudinal axis 122. In addition, the end 326 of the retainer sleeve 128 engages the shoulder surface 216, such that the shoulder surface 216 causes the end 326 to expand to the second portion diameter 218. The expansion of the end 326 further causes the retainer sleeve 128 to be centered around the connector body 124 and the interference portion 212.

[0148] At step 520, the press 532 is disengaged (e.g., released) from engagement with the connector assembly. Fig.32 and Fig.33 As shown, press 532 is raised above and away from the completed connector assembly 120 so that connector assembly 120 can be removed from fixture 530. After retainer sleeve 128 is coupled to connector body 124, a portion of second engagement surface 214 may be uncovered and exposed to air. In some embodiments, retainer sleeve 128 covers and engages with the entire second engagement surface 214 such that after retainer sleeve 128 is coupled to connector body 124, no portion of second engagement surface 214 is visible.

[0149] In another embodiment, the mechanical mechanism or tool can be configured to press the retainer sleeve onto the connector body while engaging multiple latches. That is, the mechanical mechanism or tool can be operated to push the retainer sleeve onto the connector body and press multiple latches in a single action. In this way, a separate station is not required to engage multiple latches on the retainer sleeve.

[0150] Fig.34 A schematic diagram of a tool (such as a press head or a press tool) 600 used with a press 532 or other pressing tool is shown, and the tool 600 is used to assemble the connector assembly 120 on a fixture similar to the fixture 530. As shown, the tool 600 is in an initial unloaded position. The tool 600 can be adapted to be mounted on a press 532 or other pressing tool (such as a hydraulic cylinder or a pneumatic cylinder or other structure), and it also includes an actuator. In this way, the tool 600 can be moved up and down by the actuator during operation. In multiple embodiments, the press 532 or other pressing tool can be connected to the tool 600; however, the tool 600 can also replace the press 532 or other pressing tool without departing from the scope of the present invention.

[0151] like Fig.34 and Fig.35 As shown generally, the tool 600 may include an adapter sleeve 602, an adjustment sleeve 604, a collet sleeve 606, and a tool body 608, as well as a plurality of latch engagement members 610 (e.g., including bearing members, such as spherical members, ball bearings, or other engagement members sized, designed, or otherwise configured to engage latches). The tool 600 is configured to position or apply the retainer sleeve 128 to the connector body 124 (wherein the sealing member 132, the protective ring 136, the grab ring 140, the disassembly body 154, the barrel 146, etc. are fixed) and also engage or press the latches 310 to their locked / engaged positions relative to the connector body 124, or further locked / engaged positions. In this regard, the tool 600 is configured to engage or press the latches 310 to their engaged or locked positions substantially simultaneously with the retainer sleeve 128 being positioned on the connector body 124. That is, engagement members 610 are configured to engage latches 310 and move latches 310 toward their engaged or locked positions upon or simultaneously with positioning of retainer sleeve 128 onto connector body 124 .

[0152] The adapter sleeve 602 can be fixedly connected to the pressing tool via a cutout 612 (e.g., notch, slot) at a distal end 614 of the adapter sleeve 602. In this way, the adapter sleeve 602 can be retained in the pressing tool and cannot move relative to the pressing tool. The adapter sleeve 602 also defines a cavity 616 (i.e., pocket) configured to receive a spring 618 and a portion of the collet sleeve 606. That is, the cavity 616 is designed to cover or protect the spring 618.

[0153] In one example, the adapter sleeve 602 can have a flange 620 that is configured to be received in a groove 622 defined in the tool body 608 when the tool body 608 is attached to the adapter sleeve 602, however alternatives are possible. In other examples, the tool body 608 can include a shoulder that engages with a groove defined in the adapter sleeve 602. The tool body 608 can be threadedly connected to the distal end 614 of the adapter sleeve 602 so that the tool body 608 and the adapter sleeve 602 are fixed together as a single piece. When the tool body 608 is fastened, tightened or fixed to the adapter sleeve 602, a cap screw 624 can be used as an anchor as a means of clamping the tool body 608. In some examples, a hexagonal screw or an Allen key may be formed in the tool body 608 as a means for fastening the tool body 608 to the adapter sleeve 602, however alternatives are possible (e.g., a hexagonal structure for engagement by a wrench or other tool or other structure for engagement by a tool may be employed without departing from the scope of the present disclosure). Since the adapter sleeve 602 is connected to the actuation mechanism of the press tool, the adapter sleeve 602 and the tool body 608 may be actuated up and down together when the retaining sleeve 128 is installed on the connector body 124.

[0154] The adjustment sleeve 604 can be threadedly connected to the collet sleeve 606. The adjustment sleeve 604 can be used to set or calibrate the linear distance that the collet sleeve 606 can travel when the retainer sleeve 128 is pushed onto the connector body 124, for example, to adjust the engagement (e.g., force, pressure applied, distance traveled, etc.) of the latch engagement member 610 and / or the depth or amount that the retainer sleeve 128 is positioned or received on the connector body 124. The adjustment sleeve 604 can be adjusted back or forward to achieve the desired calibration, and the locking nut 626 can be positioned, tightened, etc. to hold or lock the adjustment sleeve 604 in place. When a load or resistance is detected on the latch engagement member 610, this indicates that the latch engagement member 610 is aligned and engaged with the latch 310 of the retainer sleeve 128. Adjustment using the adjustment sleeve 604 can assist or otherwise allow calibration of the latch engagement member 610 to ensure proper engagement or positioning of the latch engagement member relative to the latch 310.

[0155] Go to Fig.35 , the tool 600 is shown in a loaded or completed operating position. When the retainer sleeve 128 is installed on the connector body 124, the adapter sleeve 602 and the tool body 608 will be moved along the longitudinal axis X from a retracted or unloaded position (see Fig.34 ) to the extended or loaded position as shown.

[0156] The pressing tool is operated to push the retainer sleeve 128 to a set depth on the connector body 124, which is controlled by the hydraulic or pneumatic cylinder of the press. In some examples, the adjustment sleeve 604 can be used to set the depth of the retainer sleeve 128 installed on the connector body 124. The retainer sleeve 128 can be installed on an interference portion similar to the interference portion 212 of the connector body 124 until it is positioned in place as described above. During operation, the adjustment sleeve 604 of the tool 600 will begin to move to position the retainer sleeve 128 on the connector body 124, and once the retainer sleeve 128 is installed on the connector body 124, the end face 628 of the adjustment sleeve will engage or contact the pallet plate or structure 630. In multiple embodiments, the components of the protective ring 136, the grab ring 140, the disassembly body 154, the barrel 146, etc. will be received in the connector body 124 before the positioning of the retainer sleeve 128. In additional or alternative embodiments, the assembly of the protective ring 136, the grab ring 140, the disassembly body 154, the barrel 146, etc. can be received in the retainer sleeve 128 and positioned in the connector body 124 when the retainer sleeve 128 is positioned on the connector body 124. The pallet 630 includes or is attached to a tray or other fixing mechanism, or is designed to hold the connector body 124 or hold an assembly member 632 (e.g., a connector subassembly, such as the connector body 124 in which the sealing member 132, the protective ring 136, the grab ring 140, the disassembly body 154, the barrel 146, etc. are contained). The tray can be moved on a conveyor so that the assembly members are arranged to move along the conveyor to align with the tool 600 respectively, so as to assemble the retainer sleeve 128 thereon.

[0157] During operation, the retainer sleeve 128 is assembled within the tool body 608 of the tool 600. The tool body 608 includes a stepped hole or stepped socket 634 formed integrally with the tool body 608. The tool body 608 defines a first opening 636 having a first inner diameter D1 and a second opening 638 having a second inner diameter D2 different from the first inner diameter D1. A step 640 can be configured between the first opening 636 and the second opening 638. The first inner diameter D1 can be smaller than the second diameter D2. In some examples, the second diameter can be twice the first diameter D1. The step 640 can be configured to cooperate with the retainer sleeve 128 to mount the retainer sleeve 128 to the assembly member 632 when the tool 600 is facing or in a loading or finishing position.

[0158] The tool body 608 also defines a groove, hole or slot 644 for receiving a mounted and carried latch engagement member 610. The diameter of the latch engagement member 610 can be about 4.5 mm, however alternatives are possible. The inside of the collet sleeve 606 includes an inclined surface or tapered surface 646 opposite the threaded outer side of the collet sleeve 606, which is threadedly engaged with the adjustment sleeve 604 and the locking nut 626. The collet sleeve 606 is designed to surround a portion of the connector body 124, which in turn holds the latch engagement member 610 in place to prevent the latch engagement member 610 from falling outside the connector body 124. During operation of the tool 600, the latch engagement member 610 is configured to move along the inclined surface or tapered surface 646 of the collet sleeve 606. The latch engagement member 610 can slowly begin to engage the latch 310 before fully engaging with the latch 310. The angle of the inclined or tapered surface 646 engages or guides the latch engagement member 610 to assist or otherwise provide a desired travel distance for the latch engagement member 610 so that the latch engagement member 610 simultaneously engages or presses the latch 310 when the retainer sleeve 128 is pressed onto the connector body 124. In this regard, as the tool 600 moves downward or otherwise toward the connector body 124, the latch engagement member 610 travels along or is otherwise guided and engaged by the surface 646 to move or engage the latch engagement member radially inward toward the latch 310 of the connector body 124, or guide the latch engagement member radially inward toward the latch 310 of the connector body 124 (e.g., press the latches to or further into a locked position of the latches relative to the connector body). The travel distance of the collet sleeve 606, and therefore the travel distance of the latch engagement member 610, can be set by the adjustment sleeve 604. In some examples, the inclined surface or tapered surface 646 of the collet sleeve 606 is between about 10 degrees and about 25 degrees. In some examples, the inclined surface or tapered surface 646 of the collet sleeve 606 is less than 20 degrees. In some examples, the inclined surface or tapered surface 646 of the collet sleeve 606 is at least 15 degrees. In some examples, the inclined surface or tapered surface 646 of the collet sleeve 606 is about 15 degrees.

[0159] The tool body 608 of the tool 600 moves downward to push the retainer sleeve 128 until a predetermined resistance is reached. The predetermined resistance is built into the pressing tool and is controlled and measured in a cylinder connected to the tool body 608. The pressing tool can have a load sensor that measures the resistance. Once the resistance load is reached, the tool body 608 of the tool 600 can push the retainer sleeve 128 to the optimal set distance on the connector body 124 (for example, until the retainer sleeve is fully engaged or fully positioned relative to the interference portion). The adjustment sleeve 604 is designed to move first when actuated until the end face 628 of the adjustment sleeve 604 contacts the support plate 630, thereby allowing the collet sleeve 606 to be pressed against or pushed back against the spring 618. When the adjustment sleeve 604 contacts the support plate 630, the collet sleeve 606 can be pressed back toward the cavity 616 of the adapter sleeve 602. That is, the collet sleeve 606 can be pressed against the spring 618 in the distal direction 601 relative to the connector body 124. When the tool 600 begins to be actuated using a pressing tool, the latch engagement member 610 is configured to move simultaneously as the retainer sleeve 128 is pushed onto the connector body 124. That is, when the collet sleeve 606 is pushed back against the spring 618, the latch engagement member 610 can simultaneously slide along the inclined surface 646 of the collet sleeve 606 and align to engage the latch 310. The inclined surface 646 is designed to push or press the latch engagement member 610 inwardly toward the retainer sleeve 128. The latch engagement member 610 can apply force to the latch 310 without damaging the latch 310. The latch engagement member 610 can push the latch 310 inwardly, activate, bend or deform the latch 310 to provide an effective latch or engagement with the connector body 124. In various embodiments, the latch engagement member 610 may apply or form features, such as detents or other noticeable deformations, on the surface of the latch 310 to thereby verify adequate engagement. In additional or alternative embodiments, the latch engagement member 610 will not apply any surface deformation, indentations, detents, etc., to the surface of the latch 310.

[0160] It should be understood that the amount of force with which the latch engagement member 610 pushes the plurality of latches 310 can be controlled by adjusting the adjustment sleeve 604. The adjustment sleeve 604 and the locking nut 626 set the amount of depth to which the latch engagement member 610 will engage the latches 310 of the retainer sleeve 128. The adjustment sleeve 604 is set away from the end 648 of the collet sleeve 606 (see Fig.34 ), the greater the force with which the latch engagement member 610 can push the latch 310. When linear adjustment is performed, the locking pin 646 can be configured to extend through the collet sleeve 606 and the adapter sleeve 602 to stop or prevent rotation or rotation of the collet sleeve 606. The locking nut 626 can be used to lock the adjustment sleeve 604 in a desired position after setting.

[0161] When the operation is completed, the tool 600 begins to lift away from the assembly member 632, and the spring 618 begins to bias the collet sleeve 606 in the proximal direction 603 relative to the connector body 608, which allows the latch engagement member 610 to slide off the inclined surface 646 of the collet sleeve 606 to release from the latch 310 of the retainer sleeve 128. Although the spring 618 can be configured to safely return the collet sleeve 606 to its initial position after operation, in other embodiments, the gravity and weight of the collet sleeve 606 may be sufficient to return the collet sleeve 606 to its pre-operation position. When the pressing operation is completed, the spring 618 can be used to bias the collet sleeve 606 in the proximal direction 603 relative to the connector body 608 to its initial position.

[0162] Reference Figure 36 to Figure 38 , depicting multiple views of another tool or tool assembly 700. The tool 700 can be used as a stand-alone station for pressing the tool. That is, the retainer sleeve 128 is pressed onto the connector body 124, and then the assembly component can be moved (e.g., via a tray on a conveyor) to another station including the tool 700. The tool 700 includes a plurality of latch engagement portions 702, each of which is configured to engage with a corresponding latch 310 on the retainer sleeve 128. That is, the latch engagement portions 702 can be aligned with the latch 310 to press the latch 310 inwardly, thereby providing an effective latch or engagement with the connector body 124. The latch engagement portions 702 of the tool 700 can be controlled to actuate simultaneously to press the latch 310 of the retainer sleeve 128.

[0163] Figure 39 to Figure 40 An exploded view of a tool 700 is shown. The tool 700 may include a mounting plate 704 that may be attached to a pressing device. The tool 700 includes a tool housing 706 that may be mounted within an opening 708 defined in the mounting plate 704. The mounting plate 704 is shown with two tools 700a, 700b mounted thereto, however alternatives are possible. The latch engagement portion 702 of the tool 700a is depicted as being in an actuated or engaged position relative to the release sleeve 128 such that the latch engagement portion 702 presses or pushes the latch 310. The latch engagement portion 702 of the tool 700b is shown as being in a disengaged position relative to the release sleeve 128.

[0164] The tool housing 706 may include mounting block members 710 equally spaced about the periphery thereof. The mounting block member 710 defines fastener openings 712 that may receive mechanical fasteners (not shown). The latch engagement portion 702 may be attached to the mounting block member 710 via the fastener openings 712.

[0165] Figure 41 to Figure 44The latch engagement portion 702 of the handpiece 700a is shown in an actuated or engaged position with the latch 310 of the retainer sleeve 128. The latch engagement portion 702 may be configured to simultaneously push the latch 310 of the retainer sleeve 128. The latch engagement portion 702 may be controlled via a cylinder of a pressing device.

[0166] Other additional process steps may be included, or steps may be eliminated, without departing from the scope of the present disclosure; for example, multiple latches may be engaged by a mechanical mechanism, such as press-in, to further improve their engagement.

[0167] In another embodiment, it should be understood that, for example, the retainer sleeve 128, the protective ring 136, the grab ring 140, the barrel 146, and the disassembly body 154 form a subassembly during the production process. The subassembly can then be pressed onto the connector body 124 provided with the sealing member 132. According to an embodiment of the present disclosure, during the production process of the connector assembly 120, the latch member 311 may need to be pressed against the above-mentioned subassembly to allow the latch member 311 to engage with the locking surface 210. That is, one or more internal components of the subassembly can be pressed to a degree that allows the latch member 311 to engage with the locking surface 210. After the pressing force is released, such as at step 520, one or more internal components of the subassembly exert tension on the retainer sleeve 128. The tension locks each of the plurality of latches 310 against the locking surface 210, thereby substantially preventing the retainer sleeve 128 from rotating about the longitudinal axis 122. In this regard, the engagement of the plurality of latches 310 with the locking surface 210 also helps provide the force necessary to maintain the integrity of the connector assembly 120 when (high pressure) fluid is passing therethrough.

[0168] Figure 45 to Figure 45 A is a schematic diagram and image illustration showing the above step 502. In the depicted example, at least one robotic arm 800 can be used to grab one of the connector bodies 124 moving along the longitudinal axis 122 on the conveyor belt 802. The connector body 124 is then placed into a carrier 804 for assembly. The carrier 804 can be configured to receive two connector bodies 124, however, alternatives are possible. The carrier 804 moves adjacent to the conveyor belt 802 along the longitudinal axis 122.

[0169] Figure 46 to Figure 46 A is a schematic diagram and pictorial illustration of a carrier 804 used to move the connector body 124 to various stations during the assembly process.

[0170] Figure 47 to Figure 47A is a schematic diagram and graphic illustration showing at least one cylinder 806 movable along a vertical axis 808. The cylinder 806 includes lubricant so that when lowered into the cavity of the connector body 124, lubricant is applied therein. As shown in FIG. 48 , the lubricant may be applied before the sealing member 132 is inserted into the connector body 124. In other examples, the lubricant may be applied after the sealing member 132 has been inserted into the connector 124. Thus, there may be two lubrication stations during the assembly process, however alternatives are possible.

[0174] As described in method step 514, press 532 may be used to press retainer sleeve 128 onto the inner component and connector body 124. As described in method step 518, retainer sleeve 128 may be pressed until latch 310 engages in locking surface 210.

Each of the plurality of latch engagement portions 702 of the tool 700 is configured to engage with a corresponding latch 310 on the retainer sleeve 128 to press the latch 310 inwardly to provide a positive latch or engagement with the connector body 124 .

[0176] Figure 52 to Figure 52A is a schematic diagram and pictorial illustration showing a completed connector assembly 120 that has been removed from carrier 804 by grab arm 820. Grab arm 820 is configured to place connector assembly 120 into bin 822.

[0177] The above description is given by way of example, rather than by way of limitation. Considering the above disclosure, those skilled in the art can make modifications within the scope and spirit of the present disclosure, including various ways of connecting the disassembly body 154 and the barrel 146. For example, an axial slot can be formed along the length of the disassembly body 154. The slot can be large enough to fully compress the disassembly body 154 to pass through the proximal assembly of the barrel 146, and expand to engage the second inner shoulder 462 on the barrel 146 with the protective shoulder 404 to connect these components. Similarly, although each of the multiple latches 310 is integrally formed with the retainer sleeve 128, and the locking surface 210 is integrally formed with the connector body 124, the positions of these components can be reversed, and other configurations of the latch and the lock can be used. In addition, the various features of the present disclosure can be used alone, or in different combinations from each other, and are not intended to be limited to the specific combinations described herein. Therefore, the present disclosure is not limited by the illustrated embodiments.

[0178] In this specification, adjectives such as left and right, top and bottom, first and second can be used to distinguish an element or action from another element or action, without necessarily requiring or implying any actual such relationship or order. In addition or alternatively, references to element positions herein (e.g., top, bottom, above, below) can be used only to describe the orientation of various elements in the figure. It should be noted that, according to various example embodiments, the orientation of various elements can be different, and this variation is intended to be included in the present disclosure. Where context permits, references to parts, integers or steps (or the like) should not be interpreted as being limited to one of the parts, integers or steps, but can be one or more of the parts, integers or steps.

[0179] As used herein with respect to structural features (e.g., to describe shape, size, orientation, direction, relative position, etc.), the terms "approximately," "about," "substantially," and similar terms are intended to encompass minor variations in structure that may result from, for example, manufacturing or assembly processes, and are intended to have a broad meaning consistent with commonly accepted usage by those of ordinary skill in the art to which the disclosed subject matter belongs. Accordingly, these terms should be interpreted as indicating that insubstantial or unreasonably modified or altered versions of the described and claimed subject matter are considered to be within the scope of the disclosure as described in the appended claims.

[0180] It should be noted that the term "exemplary" and variations thereof, as used herein to describe various embodiments, are intended to indicate that such embodiments are possible examples, representations, or illustrations of possible embodiments (and such terms are not intended to imply that such embodiments are necessarily unusual or optimal examples).

[0181] The term "connection" and its variants used herein refer to connecting two components directly or indirectly to each other. This connection can be constant (e.g., permanent or fixed) or removable (e.g., removable or releasable). This connection can be achieved by: two components are directly connected to each other, two components are connected to each other using a separate intermediate component and any additional intermediate components that are connected to each other, or two components are connected to each other using an intermediate component that is integrally formed into a single entity with one of the two components. If "connection" or its variants are modified by additional terms (e.g., direct connection), the general definition of "connection" provided above is modified by the general language meaning of the additional terms (e.g., "direct connection" means the connection of two components without any separate intermediate components), resulting in a narrower definition than the general definition of "connection" provided above. This connection can be a mechanical, electrical or fluid connection.
