[0002] This application claims priority to U.S. Patent Application No. 63 / 377,921, filed Sep. 30, 2022.

[0003] Incorporation by Reference

[0004] The disclosure and drawings of U.S. Patent Application No. 63 / 377,921, filed Sep. 30, 2022, are incorporated herein by reference as if set forth in full herein. Technical Field

[0005] This disclosure generally relates to pipe fittings. More specifically, this disclosure relates to push-on fittings. Background Art

[0006] Conduits are used to convey a variety of liquids and / or gases. Connectors, couplings, and fittings are used to join conduits in various ways so that the conduits can be arranged in different configurations to move fluid through the conduits. The conduits can be rigid or hard, such as metal or plastic pipes used in domestic plumbing applications, or the conduits can be flexible. Connectors are used for end-to-end connection of conduits, or the connectors can direct the conduits in different directions relative to the conduit axis. For example, a connector can be used to change the direction of a pipe, such as at an angle of 45° or 90° relative to the flow path of the pipes connected by the connector. Connectors can also be used to branch or split pipes in different directions. For example, a single pipe section can be joined by a T-fitting or a Y-fitting or a multi-conduit fitting or a diameter change.

[0007] In some cases, it is beneficial for a user to identify when a conduit is fully inserted into a connector or fitting. For an outer diameter seal configuration, it can be challenging to design a push-on fitting with an indication feature without adding complexity or cost due to materials, components, etc. Thus, there is a need in the art for an indication feature for push-on fittings that is simple, low-cost, and compatible with a variety of conduits. This disclosure addresses this and other related and unrelated problems. Summary of the Invention

[0008] This application relates to a connector having an indicia feature for providing visibility within a connector body. For example, the connector may include a connector body made of a transparent or opaque material to provide visibility through the connector body. The connector body defines an indicia region that provides a visual indication of two positions of a conduit. A first position of the conduit includes a position where the conduit is inserted beyond a seal portion of the connector but not fully inserted to a predetermined depth. And, a second position of the conduit includes a position where the conduit is sealed and fully inserted into the connector body to a predetermined depth (e.g., the predetermined depth includes a depth at which an end of the conduit engages a conduit stop of the connector body).

[0009] In some examples, the connector may be coupled to a pipe such that the connector is not easily removable. In other examples, the conduit may be detachable from the connector to allow the connector to be reused (e.g., using a disassembly tool or other suitable tool or mechanism). Thus, the connector can be detachable without the risk of damaging the conduit or the connector.

[0010] Aspects of the present disclosure relate to a connector assembly that includes a connector body having a first end defining a first opening and an opposite second end defining a second opening. The connector body defines a fluid passage extending through the first end and the second end such that the first end and the second end are in fluid communication. The connector body includes at least a portion having a light-transmissive plastic construction, wherein the portion of the connector body including the light-transmissive plastic construction is provided as a push-on fitting and at least partially defines a visible indicia region.

[0011] The connector assembly may include a first sealing member and a second sealing member. The first sealing member is configured to be inserted into the first opening of the connector body to form a sealing engagement with a first fluid conduit, and the second sealing member is configured to be inserted into the second opening of the connector body to form a sealing engagement with a second fluid conduit.

[0012] The connector assembly may include a first retaining ring and a second retaining ring. The first retaining ring has a plurality of teeth configured to be coupled to a first fluid conduit,

[0013] and the second retaining ring has a plurality of teeth configured to be coupled to a second fluid conduit.

[0014] The connector assembly may include a first protective ring and a second protective ring. The first protective ring is partially positioned within the connector body at the first end of the connector body and is located between the first retaining ring and the first sealing ring. The second protective ring is partially positioned within the connector body at the second end of the connector body and is located between the second retaining ring and the second sealing ring.

[0015] The connector assembly may include a first end cap and a second end cap. The first end cap is configured to be mounted on the connector body at a first end portion of the connector body, and the second end cap is configured to be mounted on the connector body at a second end portion of the connector body. A visible indication area provides a visible indication of two positions of a first fluid conduit and a second fluid conduit within the connector body. The first positions of the first fluid conduit and the second fluid conduit include positions where the first fluid conduit and the second fluid conduit are respectively inserted beyond a sealing portion of the connector body but not fully inserted to a predetermined depth defined by a conduit stop within the connector body. The second positions of the first conduit and the second conduit include positions where the first conduit and the second conduit are sealed and fully inserted to a predetermined depth within the connector body.

[0016] In some examples, the first end cap and the second end cap have a reduced transparency relative to the connector body such that the end caps at least partially restrict visibility of the conduits to define a portion or an end (e.g., a starting point or an initial end) of the indication area. In this regard, the end caps may define a first end (or starting point / portion) of the indication area such that when a portion of the conduit is visible / appears to pass by the end cap, a visual indication is provided that the conduit is in the first position (i.e., engaged by the sealing portion but not inserted to the predetermined depth).

[0017] The first end cap may have an inner wall and a first support wall. The inner wall has a stepped configuration, and the first support wall is for supporting a first retaining ring when the first end cap is attached to the connector body. The second end cap may have an inner wall and a second support wall. The inner wall has a stepped configuration, and the second support wall is for supporting a second retaining ring when the second end cap is attached to the connector body.

[0018] Another aspect of the present disclosure relates to a push-on fitting that includes a connector body having a first end portion defining a first opening and an opposite second end portion defining a second opening. The connector body defines a fluid passage extending through the first end portion and the second end portion such that the first end portion and the second end portion are in fluid communication. The connector body is configured to receive a pipe and has an end stop. The connector body has a light-transmissive portion with a plastic construction.

[0019] A push - on fitting may include: a seal member configured to provide a seal with the outer diameter of a fluid conduit; a retaining ring including a plurality of teeth configured to be coupled to the fluid conduit; a protective ring that is partially positioned within the connector body and between the retaining ring and the seal ring; and an end cap configured to be mounted on the connector body. The end cap may have an inner wall and a support wall, the inner wall having a stepped configuration, and the support wall configured to support the retaining ring when the end cap is attached to the connector body. In some examples, the end cap has a reduced transparency relative to the connector body such that the end cap at least partially restricts visibility of the fluid conduit to define a portion or an end (e.g., a starting point or an initial end) of an indication area.

[0020] A push - on fitting may include an indication area at least partially defined by a light - transmissive portion of the connector body. The light - transmissive portion provides an indication of two positions of the fluid conduit, the two positions including a first position where the fluid conduit is partially inserted and sealed by the seal member and a second position where the fluid conduit is fully inserted to engage an end stop.

[0021] Another aspect of the present disclosure relates to a method of assembling a connection fitting. The method includes the step of obtaining a connector body defining a passageway extending therethrough. The connector body is configured to receive a pipe and has an end stop. The method includes the step of positioning an O - ring seal member within the passageway of the connector body; the step of positioning a protective ring adjacent an end of the connector body; and the step of positioning a retaining ring adjacent the protective ring such that the protective ring is partially positioned within the connector body between the retaining ring and the seal ring. The method further includes the step of positioning an end cap on the connector body. The retaining ring may be held with the help of the end cap. The retaining ring is configured to grip the outer surface of the conduit.

[0022] The connector body has a light - transmissive portion with a plastic construction. The connector body includes an indication area at least partially defined by the light - transmissive portion of the connector body. The indication area provides an indication of two positions of the conduit, the two positions including a first position where the conduit is partially inserted and sealed by the O - ring seal member and a second position where the conduit is fully inserted to engage the end stop.

[0023] In some examples, the conduit is removably configured to be inserted into the passageway of the connector body. The two positions of the conduit are visible to the naked eye.

[0024] These and other features and advantages will be apparent by reading the following detailed description and viewing the associated drawings. Various additional aspects will be set forth in the following description. These aspects may relate to individual features and combinations of features. It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory and are not restrictive of the broad concepts on which the embodiments disclosed herein are based.

[0046] This application relates to push - on fittings for conduits (e.g., PEX tubes, copper tubes, PVC tubes, CPVC tubes, etc.). These fittings are configured to provide a seal with the end of a conduit. That is, a substantially waterproof connection can be formed. These push - on fittings can be used with fluid conduits of different diameters, including fluid conduits with diameters less than 0.25 inches to fluid conduits with diameters greater than 2 inches or larger.

[0047] Figure 1 Illustrated is an exemplary connector assembly 100 (e.g., a push - on fitting) in accordance with the principles of the present disclosure. The connector assembly 100 has a first end 102 and an opposite second end 104, and the first end 102 and the second end 104 are configured to receive and connect to a part of a pipe fitting or tubular member (e.g., a pipe, a conduit, etc.), particularly to receive and connect to the end of a pipe fitting. As shown, a first conduit 106 is positioned at the first end 102, and a second conduit 108 is positioned at the second end 104. Figure 2 Shown is the connector assembly 100 with the first conduit 106 and the second conduit 108 removed.

[0048] Figure 3Shows an exploded view of the connector assembly 100. The connector assembly 100 may include a connector body 110, a sealing member 112 (e.g., an annular O-ring sealing member), a protective ring 114, a retaining ring 116, and an end cap 118. The connector body 110 may be a cylindrical body having a first end 120 and an opposite second end 122, and the first end 120 and the second end 122 together define a fluid passage or body interior 124 that extends longitudinally through the first end 120 and the second end 122, thereby fluidly connecting the first end 120 and the second end 122. The first end 120 and the second end 122 may be the inlet ends of the connector body 110 for receiving the ends of corresponding conduits. As shown, each of the first end 120 and the second end 122 of the connector body 110 includes a sealing member 112, a protective ring 114, a retaining ring 116, and an end cap 118. The end cap 118 is configured to facilitate holding the sealing member 112, the protective ring 114, and the retaining ring 116 at the first end 120 and the second end 122 of the connector body 110. When the end cap 118 is respectively installed at the first end 120 and the second end 122 of the connector body 110, portions of the transparent connector body 110 may be covered.

[0049] The connector assembly 100 can be made in a variety of configurations and sizes designed for handling various fluid applications. For example, the connector assembly 100 may include a straight connector body or fitting, an elbow connector body or fitting, a T-shaped connector body or fitting, a blind-end connector body that blocks flow, a connector body configured to receive fluid conduits of different diameters, an angular connector body, a multi-way (or 4-way) connector body, a Y-shaped connector body, a T-Y-shaped connector body, another type of connector body, or a combination of connector bodies.

[0050] The connector body 110 can be constructed as a single piece and include a single integral unitary part that cannot be separated without damaging the first conduit 106 and the second conduit 108 or the connector body 110. The connector body 110 can be made of plastic or other polymeric materials suitable for the intended application, such as polyphenylsulfone (PPSU), although alternatives are possible. At least a portion of the connector body 110 may include a light-transmissive plastic construction, for example, to allow visibility through that portion of the connector body. Using a plastic material can help reduce the complexity, number of components, and cost of the connector. In other examples, the connector body 110 may include an observation window for allowing visual inspection of the first conduit 106 and the second conduit 108 during insertion. That is, only the portion of the connector body 110 that includes the observation window may be made of a transparent material to provide visibility of the indication area 126 (see Figure 2 ).

[0051] In some examples, the connector assembly 100 may include a tube liner (not shown) that may be retained within the conduits of the connector assembly 100. For example, the first conduit 106 and the second conduit 108 may each include a tube liner (not shown) to prevent light from transmitting therethrough. The advantageous feature of having a tube liner allows the use of a transparent connector body 110 in applications where light transmission is not preferred or not permitted by relevant rules or standards but a visible indication of complete insertion of the conduit is desired.

[0052] In still other examples, separate elements (such as snap rings, C - rings, caps, sleeves, or similar components) (not shown) may be used to cover any transparent portion or section of the connector body 110 to prevent light transmission. That is, a separate element may be placed on the outer side of the transparent connector body 110 to limit light penetration. In certain examples, the separate element may be placed within the recess 10 of the connector body 110.

[0053] In the example shown, the entire connector body 110 is constructed of plastic, although alternatives are possible. As such, the entire connector body 110 may be light - transmissive or transparent to provide or at least partially define an indication area 126 for viewing the interior 124 of the body. In other examples, at least a portion of the connector body 110 may be transparent to allow visibility of the indication area 126. Even when end caps 118 are mounted at the first end 120 and the second end 122 of the connector body 110, a visible area including the indication area 126 remains on the connector body 110.

[0054] Turning to Figure 4 , a cross - sectional view of the connector assembly 110 is depicted. The first conduit 106 is shown as being fully inserted into the connector body 110, and the second conduit 108 is shown as being partially inserted into the connector body 110. The connector assembly 110 provides a visible indication of the two positions of the conduits within the indication area 126. The first position of the first conduit 106 includes a position where the first conduit 106 is inserted beyond the seal portion of the connector body 110 but not fully inserted to a predetermined depth 134. That is, as Figure 4 shown, the conduit may be partially inserted into the connector body 110 from the first end 120 and / or the second end 122, where the insertion of the conduit passes or exceeds the seal member 112. The second position of the first conduit 106 includes a position where the first conduit 106 is sealed and fully inserted within the connector body 110 to the predetermined depth 134 (e.g., the predetermined depth includes the depth at which the end of the conduit engages the conduit stop of the connector body).

[0055] In the example shown, end cap 118 is not transparent, although alternatives are possible. Thus, when end cap 118 is installed onto connector body 110, portions of transparent connector body 110 are covered such that only indicator region 126 of connector body 110 is shown.

[0056] Indicator region 126 provides visibility within interior 124 of the body of connector body 110 for visual inspection by the naked eye of the ends of first conduit 106 and second conduit 108. Indicator region 126 can have a length L defined along length L1 of connector body 110 (see Figure 2 ). In some examples, length L of indicator region 126 can be defined between distal ends 12 of end cap 118. It should be understood that the size of end cap 118 can change length L of indicator region 126. That is, as the coverage of end cap 118 on connector body 110 changes, length L of indicator region 126 of connector body 110 can change. Further details regarding end cap 118 will be described with reference to Figure 9 .

[0057] Returning again to Figure 2 , connector body 110 defines first cavity 128 and second cavity 130 (e.g., bore, receptacle, etc.) for receiving first conduit 106 and second conduit 108, respectively. First cavity 128 and second cavity 130 are non-threaded cavities, although alternatives are possible. First cavity 128 and second cavity 130 provide a tight sliding fit for the conduits when first conduit 106 and second conduit 108 are inserted. First cavity 128 and second cavity 130 allow first conduit 106 and second conduit 108 to be in fluid communication with each other. It should be understood that fluid flow can occur in either direction between first conduit 106 and second conduit 108.

[0058] Connector body 110 includes circumferential rib 132 (e.g., separator, lip, step) that is centrally located within connector body 110 between the ends of respective first cavity 128 and the second cavity to prevent further movement of first conduit 106 and second conduit 108 into connector body 110.

[0059] Circumferential rib 132 also defines a predetermined depth 134 (see Figure 4) The first conduit 106 and the second conduit 108 can each be inserted into the first cavity 128 and the second cavity 130 of the connector body 110. The predetermined depth 134 can refer to the depth at which the first conduit 106 and the second conduit 108 can each be inserted into the connector body 110 for full or complete insertion. The predetermined depth 134 is the longitudinal distance between the respective first end 120 and the second end 122 (i.e., the inlet end) of the connector body 110 and the circumferential rib 132. Axial end face stoppers 136 are defined at the opposite sides of the circumferential rib 132 at the predetermined depth 134 so that the first conduit 106 and the second conduit 108 engage with the axial end face stoppers 136 when fully inserted into the connector body 110. That is, when the first conduit 106 and the second conduit 108 are fully inserted into the connector body 110 to the predetermined depth 134, the ends 14 of the first conduit 106 and the ends 14 of the second conduit 108 (see Figure 3 ) can abut or press against the axial end face stoppers 136 of the circumferential rib 132. The circumferential rib 132 can provide a spacing or gap G between the distal ends of the first cavity 128 and the second cavity 130 of the connector body 110.

[0060] Still referring to Figure 4 , the indicating area 126 of the connector body 110 provides visibility of the first conduit 106 and the second conduit 108 during insertion. The indicating area 126 can extend longitudinally along the connector body 110 for a certain distance between the two distal ends 10 of the end cap 118. The indicating area 126 provides indication of multiple positions of the first conduit 106 and the second conduit 108, such as two positions of the first conduit 106 and the second conduit 108. Specifically, the indicating area 126 provides a visible indication of when the first conduit 106 and the second conduit 108 are partially inserted into the connector body 110 (e.g., at the first conduit position) through at least the sealing portion of the connector assembly 100 provided by the sealing member 112. The indicating area additionally provides a visible indication of when the first conduit 106 and the second conduit 108 are fully inserted into the connector body 110 to the respective axial end face stoppers 136 or the predetermined depth 134 (e.g., at the second position) through the sealing member 112 of the connector assembly 100. The partial insertion can include positions until reaching the axial end face stoppers 136 or the predetermined depth 134 of the first cavity 128 and the second cavity 130 respectively.

[0061] The sealing member 112 can be formed of an elastic material, such as rubber, EPDM, or other suitable elastomer. The sealing member 112 is shown as an O-ring having a circular cross-section. The sealing member 112 is configured to fit into the connector body 110 and seal against the connector body, and form a substantially fluid-tight seal with a conduit passing through the inner diameter of the sealing member 112. In this way, the sealing member 112 provides an outer diameter seal for the passing conduit and allows for easier insertion. For example, the sealing members 112 located at the respective first end 120 and second end 122 of the connector body 110 are respectively positioned on the outer bodies of the first conduit 106 and the second conduit 108 to provide sufficient sealing for the first conduit 106 and the second conduit 108 within the connector body 110.

[0062] The first conduit 106 can be inserted into the connector body 110 by moving the first conduit 106 into the connector body 110 along the longitudinal axis X of the connector assembly 100 in a first direction 138. The second conduit 10 can be inserted into the connector body 110 by moving the second conduit 10 into the connector body 110 along the longitudinal axis X of the connector assembly 100 in a second direction 140. As Figure 4 shown, the second conduit 108 is partially inserted into the connector body 110 but is fully sealed. That is, when the ends 14 of the first conduit 106 and the ends 14 of the second conduit 108 are only partially inserted into the connector body 110 (i.e., partial insertion position), the respective ends 14 of the first conduit 106 and the ends 14 of the second conduit 108 can be positioned at a depth less than a predetermined depth 134 within the connector body 110. That is, the respective ends 14 of the first conduit 106 and the ends 14 of the second conduit 108 do not reach or engage the axial end face stop 136 of the circumferential rib 132 of the connector body 110. Once the ends 14 of the first conduit 106 and the ends 14 of the second conduit 108 are partially inserted and pass through the sealing member 112 of the connector assembly 100, the indicating area 126 provides visibility of the respective first conduit 106 and second conduit 108.

[0063] See Figure 5, depicts a cross-sectional view of the connector assembly 100 and shows an indication area 126 that provides a visible indication of the corresponding first conduit 106 and second conduit 108 being fully inserted into the connector body 110 along the longitudinal axis X. That is, the ends 14 of the first conduit 106 and the second conduit 108 are fully or entirely inserted into the connector body 110 through the sealing member 112 (i.e., the fully inserted position) such that the ends 14 of the corresponding first conduit 106 and second conduit 108 are positioned at a depth equal to a predetermined depth 134 within the connector body 110. Once fully inserted, the ends 14 of the corresponding first conduit 106 and second conduit 108 are positioned at the predetermined depth 134 to butt against the axial end face stop 136. It should be understood that in the example depicted in Figure 5 the first conduit 106 and the second conduit 108 cannot be removed from the connector body 110, although alternatives are possible.

[0064] Figure 6 shows an exploded view of another exemplary connector assembly 100a that is similar to the connector assembly 100 except that the connector assembly 100a includes a removal ring 142. The removal ring 142 is configured to allow the first conduit 106a and the second conduit 108a to be removed from the connector body 110a. The removal ring 142 can be positioned at the first end 102a and the second end 104a of the connector assembly 100a.

[0065] Figures 7 to 8 shows the removal ring 142 assembled as part of the connector assembly 100a at the first end 102a and the second end 104a. The removal ring 142 is positioned inside the end cap 118a such that the end 16 of the removal ring 142 is not visible outside the connector assembly 100a. That is, the removal ring 142 does not have a feature that extends outside or beyond the end cap 118a when the end cap 118a is attached to the connector body 110a. Advantageously, there is no risk of the removal ring 142 being accidentally removed. The removal ring 142 can be pushed in either the first direction 138 or the second direction 140 to allow the corresponding first conduit 106a and second conduit 108a to be removed from the connector body 110a by moving backward in the third direction 144 and the fourth direction 146 respectively along the longitudinal axis X opposite to the first direction 138 and the second direction 140.

[0066] Referring to Figure 9, shows an end cap 118 disassembled from a connector body 110. The end cap 118 can be made of a colored material or subjected to a special surface polish or texture treatment to distinguish the end cap 118 from the connector body 110. The end cap 118 can be securely attached to the connector body 110 using various techniques. In one example, the end cap 118 can be ultrasonically welded to the connector body 118 at the first end 120 and the second end 122, although alternatives are possible. In other examples, as Figures 10 to 13 shown, the end cap 118 can be attached to the connector body 110 using a snap-fit connection. In still other examples, the end cap 118 can be joined to the connector body 110 using an adhesive or a threaded connection.

[0067] The connector body 110 has an outer surface 148 that includes tapered step portions 150 at the first end 120 and the second end 122. The step portions 150 provide an internal annular chamber 152 within the connector body 110 having an annular surface 154 configured to provide a seat for a seal member 112. That is, the seal member 112 can be received within the internal annular chamber 152 and pressed against the annular surface 154 to provide a sufficient seal for the first conduit 106 and the second conduit 108 within the connector body 110.

[0068] The connector body 110 includes outer flange portions 156 having end faces 158 at both the first end 128 and the second end 130. The outer flange portions 156 extend outwardly relative to the tapered step portions 150 and form the outer peripheral portion of the connector body 110. The tapered step portions 150 of the connector body 110 taper inwardly from the outer flange portions 156 toward the respective first end 120 and second end 122 of the connector body 110. That is, the tapered step portions 150 can be stepped down relative to the end face 158 of the outer flange portions 156 of the connector body 110.

[0069] The tapered step portions 150 of the connector body 110 are configured to overlap with annular steps 160 formed on the inner wall 162 of the end cap 118. When the end cap 118 is mounted to the connector body 110 from the outside, the distal end 12 of the end cap 118 can butt against the end face 158 of the outer flange portion 156, and the annular step 160 of the end cap 118 can mate with the tapered step portions 150 of the connector body 110. In certain examples, the end cap 118 can be welded to the connector body 110 at the first end 128 and the second end 130. In this way, a weld joint 164 can be formed between the annular step 160 of the cap 118 and the tapered step portions 150 of the connector body 110.

[0070] Still referring to Figure 9, the end cap 118 has an inner cavity 166, and the inner cavity 166 has a support wall 168 integrally formed with the end cap 118 for supporting the grab ring 116. The support wall 168 of the end cap 118 has an annular surface 168a and an inclined surface 168b extending from the annular surface 168a. The grab ring 116 has a ring 18 that engages with the annular surface 168a of the support wall 168 of the end cap 118 when the end cap 118 is attached to the connector body 110 (i.e., when assembling the connector assembly 100). The grab ring 116 further includes a plurality of axially inward teeth 20 that are inclined relative to the ring 18 and surround the longitudinal axis X. The plurality of axially inward teeth 20 include a proximal side 22 and a distal side 24. When assembling the connector assembly 100, the plurality of axially inward teeth 20 can be supported by the inclined surface 168b of the support wall 168. The grab ring 116 is configured to fix the first conduit 106 and the second conduit 108 within the connector body 110 respectively, and prevent the conduits 106, 108 from withdrawing from the connector body 110 and moving in the third direction 144 and the fourth direction 146 respectively. That is, the plurality of axially inward teeth 20 of the grab ring 116 are configured to clamp the outer surfaces 26 of the first conduit 106 and the second conduit 108 respectively. The grab ring 116 can be formed of metal, such as stainless steel.

[0071] When attached, the end cap 118 has a length extending over the connector body 110 to cover the seal member 112, the protective ring 114, and the grab ring 116. The protective ring 114 includes an outer flange 170 that engages with the annular step 160 of the end cap 118. Advantageously, when the outer flange 170 on the protective ring 114 engages with the annular step 160 of the end cap 118, the protective ring 114 and the end cap 118 are held together to fix the grab ring 114 between the support wall 168 of the end cap 118 and the protective ring 114.

[0072] The protective ring 114 also defines a notch or step 172 that receives the circumferential edges or lips 174 of the first end 120 and the second end 122 of the connector body 110 during assembly. The protective ring 114 includes an inclined surface 176 that is inclined inwardly and toward the distal end 178 of the protective ring 114 so as to be generally aligned with the plurality of axially inward teeth 20 of the grab ring 116. As the inclined surface 176 extends away from the grab ring 116, the inclined surface 176 tapers to a smaller diameter. The protective ring 114 can help prevent the plurality of axially inward teeth 20 from contacting and damaging the seal member 112. The protective ring 114 can be made of a suitable plastic, such as including but not limited to thermoplastics, such as nylon fiber. The plurality of axially inward teeth 20 are configured to bend radially outwardly and toward the inclined surface 176 of the protective ring 114 when the first conduit 106 and the second conduit 108 pass through the opening formed by the ring 18 and the plurality of axially inward teeth 20 of the grab ring 116.

[0073] The end caps 118 each define an opening 180 for receiving the first conduit 106 and the second conduit 108, respectively. In this way, the ends of the first conduit 106 and the second conduit 108 can be inserted through the openings 180 of the end caps 118 into the indicated area 126 of the connector body 110, which provides an indication of partial insertion and full insertion during sealing. The opening 180 also receives the removal ring 142.

[0074] Turning back again Figure 8 , the removal ring 142 is shown inserted through the opening 180 of the end cap 118. The removal ring 142 includes a tubular proximal end (e.g., free end) 182, an inclined distal end 184, and a stop flange 186 located between the inclined distal end 184 and the tubular proximal end 182. The inclined distal end 184 is configured to generally conform to the tapered shape formed by the plurality of axially inward teeth 20 of the retaining ring 116. The stop flange 186 of the removal ring 142 contacts the inner shoulder 188 of the end cap 118 during insertion to provide a snap connection, thereby preventing the removal ring 142 from moving out of the end cap 118. The inclined distal end 184 of the removal ring 142 is proximal 22 to the plurality of axially inward teeth 20, while the inclined surface 176 of the protective ring 114 is distal 24 to the plurality of axially inward teeth 20. In this way, the plurality of axially inward teeth 20 are positioned between the inclined distal end 184 of the removal ring 142 and the inclined surface 176 of the protective ring 114.

[0075] To allow the first conduit 106a and the second conduit 108a to be removed from the connector body 110a, the retaining ring 116a can be opened by axially pushing the removal ring 142 in a first direction 138 and a second direction 140 toward the plurality of axially inward teeth 20 to an extended position (e.g., using a tool), which radially outwardly moves the plurality of axially inward teeth 20 from the first conduit 106a and the second conduit 108a, thereby opening the retaining ring 116a and releasing the retaining ring 116a from the outer surfaces 26a of the first conduit 106a and the second conduit 108a, respectively. Then, the first conduit 106a and the second conduit 108a can be removed and withdrawn from the connector body 110a in a third direction 144 and a fourth direction 146. Once the first conduit 106a and the second conduit 108a are removed from the connector body 110a, the removal ring 142 can be retracted from the extended position to a retracted position.

[0076] Turning to Figures 10 to 13 , another exemplary connector assembly 100b is described. The connector assembly 100b is similar to the connector assemblies 100, 100a, except for the end cap 118b. In the example shown, the end cap 118b is attached to the connector body 110b via a snap-fit connection 190. It should be understood that the above ultrasonic welding connection example provides a smaller form factor for the connector assembly 100 compared to the snap-fit connection 190.

[0077] Each end cap 118b includes a resilient latch 192 in the form of a rectangular protrusion defined by a latch cutout 194. The latch cutout 194 extends through a side wall 196 of the end cap 118b and is generally U-shaped, although alternatives are possible. In the example shown, there are four equally spaced latches 192 positioned circumferentially around the end cap 118b, although alternatives are possible. Each latch 192 has a fixed end or base end 198 and a free end 200. The free end 200 of the latch 192 includes a hook member 202.

[0078] The connector body 110b includes a flange 204 extending circumferentially around the connector body 110b at the first end 120b and the second end 122b. The flange 204 defines a connector body passage 206 (e.g., a groove or other recessed area) including an inner surface 208. When the end cap 118b is installed at the first end 120b and the second end 122b of the connector body 110b, the resilient latch 192 is configured to bend elastically on the flange 204 of the connector body 110b. When the hook member 202 has passed over the flange 204, the hook member 202 of the resilient latch 192 is configured to snap into the connector body passage 206 so that the hook member 202 engages with the inner surface 208 of the connector body passage 206. The hook member 202 is captured within the connector body passage 206 by the flange 204. The flange 204 can be received in the top 210 of the latch cutout 194 of the end cap 118b to provide a snap-fit ​​connection.

[0079] Another embodiment of a connector assembly or pipe fitting 300 is Figures 14 to 20 The connector assembly 300 is substantially similar to Figures 1 to 13 The connector assembly 100 is shown in FIG. The disclosure of the connector assembly 100 is similar to that of the connector assembly 300, and one skilled in the art will recognize that the features of the assemblies 100, 300 may be interchanged or combined with one another. The differences between the assemblies 100, 300 are discussed below and described in detail in the accompanying drawings. Figures 14 to 20 Shown in.

[0080] like Figure 14 As shown, the connector assembly 300 includes a connector body 310 and at least one cover assembly 315 coupled to one end of the connector body 310. In the illustrated embodiment, the connector assembly 300 includes a pair of cover assemblies 315, 317 coupled to opposite ends 302, 304 of the connector body 310. Other embodiments may include only one cover assembly 315 or more than two cover assemblies coupled to respective arms or ends of the connector body 310. The connector assembly 300 also includes a respective seal, gasket or O-ring 312 (see FIG. 1 ) for each cover assembly 315, 317. Figure 15)。The O-ring 312 can be sealed on a conduit extending through the cover assemblies 315, 317.

[0081] The connector body 310 is made of a plastic material and can be transparent, although alternatives are possible. Each cover assembly 315, 317 includes an opaque cover 318 that can be attached to the connector body, which provides an insertion zone or area as described in the previous embodiments. Each cover assembly 315, 317 includes an end cap 318, a retaining ring 316, and a protective ring 314. The retaining ring 316 and the protective ring 314 are integrated with the end cap 318 to form a single assembly. That is, the retaining ring 316 and the protective ring 314 can be formed as one piece with the end cap 318. Subsequently, the end cap 318 can be attached to the connector body 310 to complete the connector assembly 300. The cover assemblies 315, 317 of the illustrated embodiment are the same, and thus, only the cover assembly 315 will be discussed in detail below.

[0082] The retaining ring 316 includes a body 319 and a plurality of protrusions or teeth 320 configured to engage the outer surface of a tube inserted into the connector assembly 300. The retaining ring 316 is received within a recess or interior 322 defined within the end cap 318. The end cap 318 includes one or more surfaces 324, 326 that are generally complementary to the retaining ring 316. The plurality of surfaces 324, 326 can include angled or otherwise inclined surfaces 326 that can restrict the movement of the teeth 320 of the retaining ring 316 along the axial direction. In this regard, the angled surface 326 can support or reinforce the retaining ring 316 along the axial direction to help prevent or restrict the disengagement of the inserted tube.

[0083] The end cap 318 can also include a flange or protrusion 328 that extends along the axial direction of the retaining ring 316 and at least partially defines the recess 322. The flange or protrusion 328 defines an opening 330 in the end cap 318 that is generally circular and sized to allow the receipt of the retaining ring 316 (i.e., having a diameter or maximum outer dimension greater than that of the retaining ring 316).

[0084] As Figures 17 to 19As shown, the protective ring 314 can be received in the opening 330 defined by the flange 328 in a mating or other manner. In this regard, the protective ring 314 can be received (e.g., by a frictional or interlocking relationship) within the opening 330 and secured to the end cap 318 within the opening. With the protective ring 314 secured within the opening 330, the retaining ring 316 is also secured to the end cap 318. That is, the protective ring 314 can block or inhibit movement of the retaining ring 316 along the axial direction of the cap assembly 315 (i.e., along the central axis 311 of the cap assembly 315). Accordingly, the retaining ring 316 is secured between the surfaces 324, 326 of the end cap 318 and the protective ring 314. The protective ring 314 can include a surface 332 configured to engage a surface 334 of the body 319 of the retaining ring 316, e.g., to inhibit movement of the retaining ring 316 in the axial direction.

[0085] As Figures 17 to 19 shown, the protective ring 314 can include a protrusion or projection 340 along its surface, and the protrusion or projection 340 can be received in a corresponding recess or notch 342 defined in the surface of the flange 328 in a mating or other manner. In this regard, the protective ring 314 can snap-fit with the flange 328 and be snap-fitted within the opening 330 such that the protrusion 340 is received within the recess 342 to secure the protective ring 314 and the retaining ring 316 to the end cap 318. The protrusion or projection 340 can extend annularly about the central axis 311 of the cap assembly 315, or one or more protrusions or projections 340 can extend only partially about the central axis 311 and be circumferentially spaced from each other. In additional or alternative embodiments, the flange 328 can include the protrusion 340, and the protective ring 314 can include the recess 342. It should be understood that other connection mechanisms or configurations are possible without departing from the scope of the present disclosure. For example, multiple protrusions and corresponding one or more grooves on the cap or protective ring are possible.

[0086] Another aspect of the present disclosure relates to a method of forming the cap assembly 315. In one example, the method can include inserting the retaining ring 316 into a recess 330 defined at least in part by the flange 328 of the end cap 318 such that the retaining ring 316 abuts one or more surfaces 324, 326 of the end cap 318. The method can include inserting the protective ring 314 into the opening 330 defined by the flange 328 until the protrusion 340 is received and secured within the corresponding recess 342 to attach the protective ring 314 to the cap, thereby securing the retaining ring 316 between the protective ring 314 and the end cap 318 and forming the cap assembly 315. This can be done before or during attaching the end cap 318 to the connector body 310.

[0087] Figures 16 to 19A cross-sectional view of the connector assembly 300 or a portion thereof is shown. As shown, the cover assembly 315 can be connected to the end 302 of the connector body 310 by any suitable method or means. The cover assembly 315 can be at least partially received within one or more cavities or recesses 313 defined within the connector body 310 and adhered to the connector body 310 by ultrasonic welding or other adhesion mechanisms such as via an adhesive, mechanical connection (e.g., friction fit or snap fit), chemical bonding, heat staking, etc.

[0088] In the illustrated embodiment, as Figures 16 to 19 shown, the flange 328 of the end cap 318 is received within the first cavity 350 of the connector body 310, and at least a portion of the protective ring 314 is received within the second cavity 352 of the connector body 310. The second cavity 352 is in communication with the first cavity and is smaller (e.g., has a smaller diameter or maximum outer dimension). The first cavity 350 and the second cavity 352 are also in communication with or at least partially define a passage 354 that passes through the connector body 310. As Figure 20 shown, the passage 354 is configured to receive one or more tubes or conduits 400, 402 for connection thereto.

[0089] A seal 312 (e.g., an O-ring) is received within the second cavity 352 and can be held in place by the protective ring 314. In this regard, the protective ring 314 includes a surface 356 that, together with the connector body 310, partially defines a chamber 358 for receiving the seal 312. The chamber 358 is also partially defined by surfaces or shoulders 360, 362 of the connector body 310 that define or abut the cavity 352.

[0090] The flange 328 defines a cavity or recess 366 (opposite the opening 350 for receiving the protective ring 314) that is configured to receive the end 302 of the connector body 310. The surface 368 of the flange 328 that abuts or is adjacent to the surface 370 of the end 302 of the connector body 310 can include one or more stepped portions. However, according to embodiments of the present disclosure, the surface 366 can be substantially flat (without stepped portions). At least a portion of the surface 368 abuts / contact the surface 370 of the connector body 310 (e.g., the surface of the connector body that at least partially defines its first cavity 350).

[0091] In some examples, surfaces 368 and 370 may be joined together by ultrasonic welding (as described in other embodiments) or other adhesion mechanisms (such as via adhesives, mechanical connections (e.g., friction fit or snap fit), chemical bonding, heat melting, etc.) to form a connection joint between surfaces 368 and 370. Additionally or alternatively, the surface of protective ring 314 and the surface of flange 328 may be joined together by ultrasonic welding or other adhesion mechanisms, such as via adhesives, mechanical connections (e.g., friction fit or snap fit), chemical bonding, heat melting, etc. to form a connection joint between the surface of protective ring 314 and the surface of flange 328. In the illustrated embodiment, the connection joint includes a stepped joint, but other joints are possible without departing from the scope of the present disclosure, such as butt joints, shear joints, tongue and groove joints or other suitable joints without departing from the scope of the present disclosure.

[0092] A method for forming connection assembly 300 may include inserting seal 312 into second cavity 352 of connector body 310. Then, the method may include inserting cap assembly 315 into first cavity 350 such that at least a portion of protective ring 314 extends into second cavity 352. And, the method may include adhering cap assembly 315 to connector body 310. In some embodiments, adhering includes ultrasonic welding end cap 318 and the surface of connector body 310, although alternatives are possible.
