Numerous embodiments of fluid line connectors and assemblies are described in detail herein. These connectors and assemblies replace the secondary latches of the past, which required some degree of physical interaction and visibility by the assembler, inspector, or servicer at the point of security. It is designed and constructed to detect proper and complete locking between connectors without the need for windows. Instead, the connectors and assemblies of the present disclosure are provided with a means by which proper and complete securement can be detected by a device remote from an immediate site of securement of the connectors, said device does not necessarily have to be in physical contact with a fixed point for detection. In this way, the connectors and assemblies can be equipped with automated, robotic and/or autonomous initial assembly, subsequent quality inspection and follow-up service technologies - such as those found in advanced manufacturing facilities in automotive production. Technology - Prepared for. Accordingly, the connectors and assemblies may prove useful in many applications, such as when an instantaneous power supply is not readily available or not readily available. Although this description discloses connectors and assemblies associated with automotive fluid lines, such as coolant fluid lines in electric vehicle vehicles, the connectors and assemblies have broader application and include aircraft fluid lines, marine fluid lines, agricultural fluid lines, and other fluids. Suitable for use on lines.

As used herein, the phrase “full securement” and its grammatical variants are used to refer to a securement in which a fluid-tight joint is formed through a fluid line connector. Additionally, unless otherwise specified, the terms radial, axial and circumferential and their grammatical variations refer to directions relative to the approximately circular shape of the passageway of the fluid line connector.

The fluid line connector and assembly can have a variety of designs, structures and components in various embodiments, which in some cases may depend on the application for which the fluid line connector and assembly is used. 1-4 illustrate a first embodiment of a fluid line connector and assembly 10. Here the fluid line connector and assembly 10 includes a fluid line connector 12 and another separate and distinct connector 14. The fluid line connector 12 has a quick-connect feature ready for connection and disconnection operations with the connector 14 and is used to connect automotive fluid lines together. In this embodiment, the fluid line connector 12 is a female connector and the connector 14 is a male connector (often referred to as a spigot). When installed, the fluid line connector 12 receives insertion of a connector 14 at a first end 16 and engages a fluid line at a second end 18. The fluid line connector 12 has an elbow and L-shaped configuration in the figure, but may have a straight and in-line configuration in other embodiments. Connector 14 may be an integral and somewhat monolithic part of a larger component, such as a vehicle battery tray or heat exchanger, or an integral and somewhat monolithic part of a fluid line, among many possibilities. It may be a monolithic part. Referring particularly to Figures 2 and 4, the connector 14 has a first flange 20 that protrudes radially outwardly of its body, is axially spaced from the first flange 20 and likewise extends the length of the connector. It has a second flange 22 that protrudes outward in the radial direction of the main body. The first and second flanges 20, 22 extend circumferentially around the connector 14. The connector 14 has an external surface 24.

In this embodiment, the fluid line connector 12 includes a body 26, an O-ring 28, an insert 30, a radio-frequency identification (RFID) chip 32, and a switch. (34) and actuator member (36); Still, in other embodiments, the fluid line connector 12 may have more, fewer, and/or other components. Referring now to Figures 3 and 4, body 26 has passages 38 defined in its structure to allow fluid flow through fluid line connector 12. The main body 26 also has a compartment 40 for receiving and placing the RFID chip 32. The compartment 40 is a space separated from the passage 38. A removable cover 42 may be provided to close the compartment 40 and enclose the RFID chip 32 therein. The main body 26 further has a pass-through portion 44 for positioning and seating the actuator member 36 within the main body 26 when assembled. When the actuator member 36 is removed from the body 26 (e.g., as shown in Figure 3), the passageway 38 and compartment 40 are separated from the passageway 38 and compartment 40. (40) They communicate with each other through a penetration portion 44 that is open to all. As perhaps best shown in Figure 4, O-ring 28 is received within passageway 38 and forms a seal between fluid line connector 12 and connector 14. The insert 30 is also received within passageway 38 and is used to help retain connector 14 when connector 14 and fluid line connector 12 are secured together. In the example of the drawing, insert 30 has a hook end that captures first flange 20 when inserting connector 14 into fluid line connector 12 to an appropriate overlap depth as shown in FIG. 4 . It has a pair of tangs 46 with sills 48. The insert 30 includes a first ring structure 50 and a second ring structure 52 bridged to each other by tangs 46. Press downs 54 on opposite sides of the second ring structure 52 are used to disassemble the connector 14 from the fluid line connector 12 and to undo the captured first flange 20. It can be compressed.

The RFID chip 32 assists in detecting proper and complete fixation between the fluid line connector 12 and connector 14. The RFID chip 32 transmits and receives radio frequency (RF) signals together with the RFID interrogator 56 (RFID interrogator). RFID interrogator 56 sends an interrogating signal 58 to RFID chip 32, which responds with an RF signal 60. In this way, proper and complete stationary detection is performed using RFID technology. For example, in a manufacturing facility, RFID interrogator 56 may be located in the middle of an assembly, inspection, and/or installation production line, while fluid line connectors and assemblies 10 and larger applications may be transported through a holding area. As a result, the RFID interrogator 56 may form an interrogation zone in which the RFID chip 32 and the RFID chip 32 attempt to communicate with each other. Depending on the manufacturing facility, RFID interrogator 56 may form an interrogation zone that extends several meters from RFID interrogator 56. In other settings, RFID interrogator 56 may be a mobile device, such as a handheld device. The RF signal 60 can transmit various data and information to the RFID interrogator 56. In one embodiment, the information conveyed may be an indication of a secure state between fluid line connector 12 and connector 14. For example, when fluid line connector 12 and connector 14 exhibit sufficient anchorage, RF signal 60 may convey sufficient anchorage information in the form of an ON signal to RFID interrogator 56. The RFID interrogator 56 can sequentially process the transmitted information. The information conveyed may also include serial number, installation location, etc.

In particular, referring to FIGS. 3 and 4, the RFID chip 32 is carried in the main body 26. Support between the RFID chip 32 and the main body 26 can be achieved in various ways. In this embodiment, the RFID chip 32 is provided in the compartment 40 and is protected by the cover 42 when installed. In this position, the RFID chip 32 is protected from exposure to fluid flows moving through passageway 38 and, depending on the particular application, is protected from external sources of contamination. RFID chip 32 has an antenna 62 that exchanges (i.e., transmits and receives) RF signals and has an integrated circuit (IC) 64 that stores data and information, among other possible functions.

The switch 34 is configured to enable and enable the RFID chip 32 to transmit and receive RF signals with the RFID interrogator 56, and to disable the RFID chip 32 to transmit and receive RF signals. It interacts with the RFID chip 32 to disable it. Additionally, the interactions may affect the functionality of the RFID chip 32 in other ways. In the embodiment shown in the figure, the switch 34 is electrically coupled to the RFID chip 32 to enable and disable RF signal transmission and reception by the antenna 62. Switch 34 may have a variety of designs, structures and components in different embodiments, which may in some cases be determined by the design and structure of the RFID chip and accompanying connectors with which it interacts. For example, switch 34 may take a mechanical, electrical, or magnetic form. In one embodiment, referring to FIGS. 3 and 4, the switch 34 is in the form of a button 66 mounted on the RFID chip 32. As best demonstrated by FIG. 4 , button 66 is positioned between RFID chip 32 and actuator member 36 and adjacent penetration 44 . When struck and physically pressed, button 66 becomes activated—due to electrical coupling with RFID chip 32—enabling antenna 62 to transmit and receive RF signals. Depending on the embodiment, the RFID chip 32 may be activated by pressing and releasing the button 66 once, or, if struck and pressed, the RFID chip 32 may be activated for the duration of the bump and pressed. there is. Conversely, pressing and releasing button 66 once may deactivate the RFID chip 32, or, if the collision and pressing are not maintained, the RFID chip 32 may be deactivated for a period of time short of the collision and pressing.

Additionally, in other embodiments, the switch 34 may be driven to activate and deactivate the RFID chip 32 by other means. Referring particularly to Figure 4, another embodiment uses a non-contact switch instead of a contact-based switch to perform prompting. A reed switch 68 is mounted on the body 26 of the fluid line connector 12, and a magnetic component 70 is mounted on the connector 14. Here, when the fluid line connector 12 and connector 14 are fully secured, the proximity between the reed switch 68 and the magnetic component 70 induces activation of the RFID chip 32. Conversely, less complete fixation and accompanying remoteness of reed switch 68 and magnetic component 70 to each other renders RFID chip 32 inactive. In this embodiment, the actuator member 36 does not need to be provided.

The actuator member 36 accommodates the abutment during the full locking operation and upon full locking between the fluid line connector 12 and the connector 14, thereby causing the switch 34 to strike. The actuator member 36 may have a variety of designs, structures and components in different embodiments, which may in some cases be determined by the design and construction of the switch 34 and accompanying connector. In the embodiment of the figure, and now referring to Figures 3 and 4, the actuator member 36 has a passageway 38 and a switch 34 to provide interrelationship between the connector 14 and the RFID chip 32. It lies in between. The actuator member 36 is carried within the body 26 of the fluid line connector 12 and is positioned and seated in the penetration portion 44. In that position, actuator member 36 has one end at passageway 38 and the other end at switch 34 . 3 and 4, the actuator member 36 is in the form of a cam member 72. The cam member 72 is one-piece and has a U-shaped profile with a base portion 74 and a pair of prong portions 76 hanging from the base portion 74. The base portion 74 is located on the switch 34 and has a first actuating surface 78 that maintains contact with the switch 34 . And each of the prongs 76 has a second actuating surface 80 located in the passageway 38 for contacting the connector 14 when inserted into the fluid line connector 12. The second operating surface 80 may be inclined relative to the axis of the connector 14 to facilitate contact with the connector 14 and induce concomitant displacement of the cam member 72.

When the fluid line connector and assembly 10 is in use, proper and complete fixation can be detected via RFID technologies. The fluid line connector 12 and connector 14 are joined together by inserting the connector 14 into the body 26 at the first end 16. The first flange 20 abuts the cam member 72 and displaces the cam member 72 upward (relative to the direction of the drawing) and toward the button 66. The first flange 20 is in surface-to-surface contact with the second actuating surfaces 80 of the cam member 72 . The cam member 72 is pressed upward and impacts the button 66 through surface-to-surface contact between the first actuating surface 78 and the opposing surface of the button 66. In this embodiment, the first flange 20 maintains contact with the cam member 72 so that the cam member 72 remains in contact with the button 66 in a fully stationary state.

In other embodiments, fluid line connector 12 includes more than a single RFID chip. In particular, referring to FIG. 3, a second RFID chip 33 is provided in addition to the first RFID chip 32. And like the first RFID chip 32, the second RFID chip 33 assists in detecting proper and complete fixation between the fluid line connector 12 and the connector 14. In this embodiment, the first and second RFID chips 32 and 33 both transmit and receive RF signals with the RFID interrogator 56. In one example, when fluid line connector 12 and connector 14 indicate full locking, first RFID chip 32 may convey full locking information to RFID interrogator 56. Conversely, if the fluid line connector 12 and connector 14 are not fully secured together, the second RFID chip 33 may convey information to the RFID interrogator 56 that is less fully secured. Additionally, with complete locking, the second RFID chip 33 does not pass less completely locking information to the RFID interrogator 56; And, if they are not completely locked together, the first RFID chip 32 does not transmit the completely locked information to the RFID interrogator 56. As in the previous embodiment, the first and second RFID chips 32, 33 may carry additional information such as serial number, installation location, etc. Whether the first RFID chip 32 carries completely fixed information or the second RFID chip 33 carries less completely fixed information is partly managed by the switch 34. In this embodiment, switch 34 interacts with both first and second RFID chips 32 and 33 and is electrically coupled to both first and second RFID chips 32 and 33. Interaction and transfer of information can be affected in a variety of ways. For example, when colliding, switch 34 may activate the first RFID chip 32 and enable it to convey completely static information, and when not colliding, switch 34 may activate the second RFID chip 32 ( 33) and can make it possible to convey less completely fixed information. Collision and absence of collision of the switch 34 may deactivate and disable the first RFID chip 32 or the second RFID chip 33.

Referring now to Figures 5-11, another embodiment of a fluid line connector and assembly 110 is presented. This embodiment has some similarities to the embodiment of Figures 1-4, which similarities may not be repeated in the description of the embodiment of Figures 5-11. The fluid line connector and assembly 110 includes a fluid line connector 112 and another separate and distinct connector 114. The fluid line connector 112 has a quick connect function ready for connection and disconnection operations with the connector 114 and is used to join together not only automotive fluid lines, but also other fluid lines in other applications. In this embodiment, fluid line connector 112 is a female connector and connector 114 is a male connector (often referred to as a spigot). Fluid line connector 112 accepts insertion of connector 114, as best illustrated in FIG. 7. In the figure, fluid line connector 112 has an elbow and L-shaped configuration, but may have a straight and in-line configuration in other embodiments. Connector 114 may be an integral and somewhat monolithic part of a larger component, such as a vehicle battery tray or heat exchanger, or an integral and somewhat monolithic part of a fluid line, among many possibilities. It can be.

Referring to FIG. 6, the connector 114 has an extension 115 and a slot 117 located at an end of the connector 114 that is inserted into the fluid line connector 112. Extension 115 may be received within a complementary cavity of fluid line connector 112 for purposes of relative rotational alignment between connectors 112, 114 and, in some embodiments, need not be provided. In some embodiments, the extension 115 may contact the first actuator member (described below) of the fluid line connector 112 and thereby facilitate its actuation. When provided, extension 115 extends axially over the inserted end of connector 114 and projects radially outwardly of the surrounding body of the connector. The slot 117 accommodates insertion of a retainer of fluid line connector 112, as described below. Slots 117 extend circumferentially around connector 114. Additionally, the connector 114 has a lamp 119. Ramp 119 provides increasing diameter at connector 114. Outer surface 113 is positioned from slot 117 and ramp 119. The connector 114 is a lamp received in the fluid line connector 112 before the extension 115 and before the slot 117 is received in the fluid line connector 112 (i.e., from right to left in the direction of FIG. 6). It is inserted into the fluid line connector 112 together with (119).

5-11, the fluid line connector 112 includes a body 126, a retainer 129, a radio frequency identification (RFID) tag 132, one or two switches 134, 135, and comprising one or two actuator members 136, 137; Still, in other embodiments, fluid line connector 112 may have more, fewer, and/or other components. Turning now to Figures 5 and 7-9, body 126 has passages 138 defined in its structure to allow fluid flow through fluid line connector 112. Additionally, the main body 126 has a compartment for receiving and placing the RFID tag 132. A cover 142 is provided to close the compartment and enclose the RFID tag 132 therein (the compartment and cover are only shown in FIGS. 5 and 7, but the RFID tag 132 is shown in FIGS. 8 and 9). may have a similar configuration to accommodate). Cover 142 is removable, but does not have to be. Additionally, although only partially shown in FIG. 5 , insert assembly 143 may be provided and transported within passage 138 and the interior of fluid line connector 112 . Depending on its design and construction, insert assembly 143 may facilitate fitting, receiving, and/or sealing between fluid line connector 112 and connector 114. For example, the insert assembly 143 may include an O-ring 145 and a carrier 147, and may also include a bushing, depending on the embodiment.

The body 126 has a structure that cooperates with the retainer 129 to provide a quick-connect function of the fluid line connector 112. Referring again to Figures 5 and 7-9, first opening 149 and second opening 151 are defined on opposing sides of the wall of the body and extend completely therethrough and lead to passageway 138. External to the wall, a first recess 153 for temporarily positioning the retainer 129 when the retainer 129 is pulled radially outward to release the connector 114 from the fluid line connector 112. and a second recess 155 is provided. The flange 157 protrudes radially outward from the wall of the body and partially protrudes sections of the retainer 129 to prevent the retainer 129 from being inadvertently released when the retainer 129 is received in the slot 117. surround it

Additionally, the body 126 has a structure intended to accommodate the assembly and installation of the actuator member(s) 136, 137. The exact design and construction of the structure may vary and may depend on the design and construction of the actuator member(s) and switch(s) used in fluid line connector 112. In the embodiment shown in the figures, now referring to FIGS. 5, 8, and 9, a first socket 159 and a second socket 161 are located in the body 126. The first socket 159 receives and retains the first actuator member 136 and in this embodiment is in the form of a slot structure. A first socket 159 is located at the inlet 163 of the passageway 138 for positioning the first actuator member 136 and is defined in the body wall near the inlet 163. To fully accommodate the first actuator member 136, the axial depth of the first socket 159 may be approximately equal to the length of the first actuator member 136. And in a similar manner, the radial width of the first socket 159 may be approximately equal to the width of the first actuator member 136. The axial depth of first socket 159 is generally aligned with the axis of passage 138 at inlet 163. The figures show an enlarged configuration of the body wall to receive the first actuator member 136 and provide a first socket 159; however, in other embodiments the receiving may be more consistent and integrated with the body 126. Enlargement can be minimized.

Referring now particularly to Figure 9, the second socket 161 receives and retains the second actuator member 137 and in this embodiment is in the form of a slotted structure. The second socket 161 is located outside the passageway 138 and on the side of the body wall for positioning the second actuator member 137 therein. To fully accommodate the second actuator member 137 , the radial depth of the second socket 161 may be approximately equal to the length of the second actuator member 137 . And in a similar manner, the axial width of the second socket 161 may be approximately equal to the width of the second actuator member 137. The radial depth of the second socket 161 is generally aligned with the radius of the passageway 138 at the inlet 163. The figures depict an enlarged structure protruding from the side of the wall of the body to receive the second actuator member 137 and provide a second socket 161, but in other embodiments the receiving portion is more consistent with the body 126. and integrated, the expanded structure can be minimized. 9, base wall 165 and a pair of side walls 167 suspended from base wall 165 together partially surround second actuator member 137 and form an external configuration when fluid line connector 112 is used. Helps prevent inadvertent contact from the elements.

The retainer 129 interacts with the body 126 to provide a quick connection function for the fluid line connector 112 so that the connector 114 can be easily inserted and retained in the fluid line connector 112 and as required or desired. It can be released and removed from it. The retainer 129 may have various designs and structures. Referring particularly to Figures 5 and 8, in this embodiment retainer 129 is a one-piece stainless steel wire spring that is inwardly biased. The retainer 129 has a first leg 169, a second leg 171, and a bridge 173 spanning between the legs. The first and second legs 169 and 171 may have substantially similar shapes and sizes. A first use position of the retainer 129 is disclosed in FIGS. 5, 8, and 9. In the first use position, the retainer 129 is carried by the body 126 with the first and second legs 169, 171 moved through the first and second openings 149, 151. )do. The first and second legs 169, 171 are located partially within the passageway 138. The connector 114 is not inserted into the fluid line connector 112 in the first use position. The second use position of the retainer 129 lacks specific description in the drawing. In the second use position, connector 114 is inserted into fluid line connector 112 and ramp 119 engages first and second legs 169, 171. The engagement may force the first and second legs 169, 171 to spread apart (i.e., radially outwardly) and move the bridge 173 radially outwardly. As insertion of the connector 114 continues, the retainer 129 is brought to a third use position where the retainer 129 is received in the slot 117. The first and second legs 169, 171 can be raised over the ramp 119 and snapped back into their positions in the first use position, but are now received in the slots 117. The first and second legs 169 and 171 are moved through the first and second openings 149, respectively. Receiving one or both of the first and second legs 169, 171 in slot 117 secures fluid line connector 112 and connector 114 together. Movement of retainer 129 between first, second and third use positions is approximately transverse and perpendicular to insertion direction 179 (FIG. 5) of connector 114 into fluid line connector 112. Move the retainer 129 in a direction, that is, the movement of the retainer is radially outward, radially inward, or up and down. As the servicer pulls the retainer 129 up to release and remove the connector 114 from the fluid line connector 112, the terminal foot 173 (FIG. 9) of the first leg 169 1 may be seated in the recess 153, and similarly, the terminal foot (not specifically shown) of the second leg 171 may be seated in the second recess 155.

Referring now to FIG. 11, the RFID tag 132 assists in detecting proper and complete locking between fluid line connector 112 and connector 114. The RFID tag 132 communicates with an RFID interrogator or reader 156 (FIG. 7). The RFID interrogator 156 sends an interrogating signal 158 to the RFID tag 132, which in turn communicates with the RFID interrogator 156. In this way, proper and complete stationary detection is performed using RFID technology. For example, in a manufacturing facility, RFID interrogator 156 may be located in the middle of an assembly, inspection, and/or installation production line while fluid line connectors and assemblies 10 and larger applications are transported through a holding area. As a result, the RFID interrogator 56 may form an interrogation zone in which the RFID chip 132 and the RFID chip 132 attempt to communicate with each other. Depending on the manufacturing facility, RFID interrogator 156 may form an interrogation zone that extends several meters from RFID interrogator 156. In other settings, RFID interrogator 156 may be a mobile device, such as a handheld device.

The RFID tag 132 is a passive RFID tag type in this embodiment, but may be of other types such as active RFID tags. Communication received from the RFID tag 132 may transmit various data and information to the RFID interrogator 156. In one embodiment, the information conveyed may be an indication of a secure state between fluid line connector 112 and connector 114. For example, when fluid line connector 112 and connector 114 indicate fully locked, RFID tag 132 may convey fully locked information in the form of an ON signal to RFID interrogator 156. And conversely, when the fluid line connector 112 and connector 114 are less fully secured, the RFID tag 132 may transmit less fully secured information to the RFID interrogator 156 in the form of an OFF signal. there is. The RFID interrogator 156 can sequentially process the transmitted information. The information conveyed may also include part serial number, installation location, etc. In an embodiment in which both switches 134, 135 and actuator members 136, 137 are mounted on fluid line connector 112, RFID tag 132 is sensitive to impingement of switches 134, 135. Alternatively, the respective states of the actuator members 136 and 137 may be transmitted based on non-impingement. For example, RFID tag 132 may convey one or more of the following: i) both actuator members 136, 137 are under-actuated and therefore both first and second switches 134, 135 are in the open state, ii) first actuator member 136 is under-actuated and therefore Accordingly, the first switch 134 is in the open state and the second actuator member 137 is actuated and the second switch 135 is therefore in the closed state. iii) The first actuator member 136 is actuated and the first actuator member 137 is thus operated. the switch 134 is in the closed state and the second actuator member 137 lacks operation so that the second switch 135 is in the open state, and/or iv) the first and second actuator members 136, 137) Both are activated and thus both the first and second switches 134, 135 are in the closed state.

The RFID tag 132 is mounted on the main body 126. Support between RFID tag 132 and body 126 can be effected in a variety of ways. In this embodiment, the RFID tag 132 is located within a compartment of the main body and is protected by a cover 142 when installed. In this position, RFID tag 132 is protected from exposure to fluid flows moving through passage 138 and, depending on the particular application, is protected from external sources of contamination. As shown in Figure 11, RFID tag 132 has an antenna 162 and has an integrated circuit (IC) 164 that stores data and information, among other possible functions. The antenna 162 and IC 164 may be carried on the substrate of the RFID tag 132. When both are provided, in one embodiment, the first and second switches 134 and 135 may be electrically coupled to the RFID tag 132 in a series arrangement. The series arrangement serves in some embodiments to form a continuity loop with beneficial circuitry and sensing functions. For example, when a continuity loop is disestablished at one or both switches 134, 135, detection of the resulting discontinuity can be easily performed. In other embodiments, the electrical coupling between the first and second switches 134 and 135 and the RFID tag 132 is, for example, the states of each of the switches 134 and 135 independent of each other, as shown above. It is possible to have an arrangement other than a series arrangement in IC 164 to affect the ability to transmit . Additionally, as previously described with reference to FIG. 3, in the embodiments of FIGS. 5 to 11, the fluid line connector 112 may include more than a single RFID tag.

5-11, the fluid line connector 112 includes i) only the first switch 134 and the first actuator member 136, ii) only the second switch 135 and the first actuator member 136. Two actuator members 137 alone, or iii) both first and second switches 134, 135 and both first and second actuator members 136, 137 may be mounted. Although the third [iii)] alternative is shown in the drawings, a skilled artisan can readily envision the first [i)] and second [ii)] alternatives by removing the other from the fluid line connector 112 in the drawings. You can.

Now returning to FIG. 10 , the first and second switches 134 and 135 are configured to display the RFID tag 132 based on collision or non-collision of the switches 134 and 135 by the first and second actuator members 136. ) is electrically coupled to the RFID tag 132 to transmit the status to the RFID tag 132. The electrical coupling may be in the form of a wire 175 extending from the first and second switches 134 and 135 to the RFID tag 132. The wiring can form a series arrangement. In the example of wires 175, wire 175 may be routed through one or more grooves in body 126 or may be embedded within a wall of body 126, among other possibilities. The first and second switches 134, 135 may take a variety of forms in various embodiments, in some cases depending on the design and configuration of the RFID tag and accompanying actuator member with which it interacts. In embodiments where both switches 134 and 135 are present relative to each other, the first and second switches 134 and 135 may take different forms. In Figure 10, the first and second switches 134 and 135 are in the form of buttons 166. When physically depressed by being struck by a particular actuator member, button 166 is in a closed state. And when not struck and not physically depressed by a particular actuator member, button 166 is in the open state.

The first and second actuator members 136, 137 receive an abutment during full locking operation and at full locking between fluid line connector 112 and connector 114, and are thereby actuated to close the switches. To do this, they sequentially collide with the first and second switches 134 and 135, respectively. The first and second actuator members 136, 137 may have a variety of designs, structures and components in different embodiments, in some cases depending on the design and configuration of the particular switch and connector. In embodiments where both actuator members 136, 137 are present relative to each other, the first and second actuator members 136, 137 may take on different shapes.

In the embodiment of the figures, now turning to FIGS. 5, 8 and 10, the first actuator member 136 is intended to facilitate detection of axial insertion of the connector 114 into the fluid line connector 112. do. The first actuator member 136 is located near the entrance 163 of the passageway 138. In general, the first actuator member 136 resembles a V-shape with its sides turned upside down. When assembled, the longitudinal extent 177 of the first actuator member 136 is arranged approximately in-line with the direction 179 in which the connector 114 is inserted into the fluid line connector 112. Longitudinal extent 177 is generally aligned with the axis of passage 138 at inlet 163. The first actuator member 136 has a base 181 and an appendage 183 dependent on the base 181. The base 181 carries the first switch 134 and is inserted and received into the first socket 159 of the main body 126. The appendage 183 can move relative to the base 181 via an arced path 185 when the first actuator member 136 receives the abutment from the connector 114. The appendage 183 is partially positioned within the passageway 138 prior to insertion of the connector 114 so that the connector's ramp 119 is in contact with the appendage 183 upon insertion, as perhaps best shown in Figure 5. is hung with The appendage 183 is maintained in this extended and suspended position when at rest and lacking contact from the ramp 119 - this is in the non-actuated state of the first actuator member 136 and when the first actuator member 136 is inactive. Configures the corresponding open state of switch 134. Then, when brought into contact, the appendage 183 moves towards the base 181 and strikes the first switch 134 - this corresponds to the operating state of the first actuator member 136 and the first switch 134. constitutes a closed state.

On one side, the appendage 183 has an external operating surface 187 that maintains general contact with the passageway 138 and connector 114. On its opposite side, appendage 183 has an internal actuating surface 189 that remains in general confrontation with first switch 134 . Protrusion 191 may extend from inner actuating surface 189 for direct impact with first switch 134 . The appendage 183 has a proximal end 193 at which the appendage 183 bends relative to the base 181 and a distal end 195. The proximal end 193 serves as a hinge and the distal end 195 constitutes the free distal end of the appendage 183. In the case of the first actuator member 136, the axis 197 of the hinge is arranged approximately orthogonal to the direction in which the connector 114 is inserted into the fluid line connector 112, and similarly passes through the inlet 163. It is approximately perpendicular to the axis of (138).

In this embodiment, the second actuator member 137 has a similar design and construction as the first actuator member 136. Returning now to Figure 9, second actuator member 137 is intended to facilitate detection of proper positioning of retainer 129 and reception of legs 169, 171 in accompanying slots 117. do. The second actuator member 137 is located at a position external to the passageway 138 and at a position lateral to the wall of the body; Still, in other embodiments not shown, the second actuator member may be located internal to body 126 and need not be external. Due to its location, unlike the first actuator member 136, the longitudinal extent 177 of the second actuator member 137 is oriented in the direction 179 in which the connector 114 is inserted into the fluid line connector 112. They are arranged roughly across the Longitudinal extent 177 is approximately orthogonal to the axis of passage 138 at inlet 163. The base 181 of the second actuator member 137 carries the second switch 135 and is inserted into and received in the second socket 161 of the main body 126. The appendage 183 is attached to the main body with its distal end 195 positioned to intersect the path along which the terminal foot 173 is lowered and positioned when the retainer 129 is in the first and third use positions. It is located outside. In this way, the terminal foot 173 can contact the appendage 183 when the legs 169, 171 are moved in the slot 117 and thereby cause actuation of the second actuator member 137. The operation of the second actuator member 137 via engagement from the terminal foot 173 is illustrated in FIG. 9 . The appendage 183 remains in the extended position when at rest and lacking abutment from the terminal foot 173 - this is in the inoperative state of the second actuator member 137 and In response to this, the open state of the second switch 135 is configured. The retainer 183 lacks abutment from the terminal foot 173 when the retainer 129 is in the second use position. Once engaged by the terminal foot 173, the appendage 183 moves towards the base 181 and strikes the second switch 135 - this determines the operating state of the second actuator member 137 and the second switch 135. ) constitutes the corresponding closed state of For the second actuator member 137, the axis 197 of the hinge is arranged approximately in-line with the insertion direction 179 of the connector 114 relative to the fluid line connector 112, , likewise generally aligned with the axis of passageway 138 at inlet 163 .

Embodiments of the fluid line connector 112 that employ the use of both the switches 134, 135 and the actuator members 136, 137 provide enhanced resolution of full locking and false-negative detection. Preclude false-negative detection readings. Turning now to FIG. 6 , first bar schematic 200 illustrates the state of first switch 134 at a specific axial insertion depth of connector 114 into fluid line connector 112 and second bar schematic 202 ) represents the state of the second switch 135 at the same axial insertion depth of the connector 114 into the fluid line connector 112. The first and second bar schematics 200, 202 are examples and may differ in other embodiments. In Figure 6, the first and second bar schematics 200, 202 are arranged next to the connector 114 and parallel to the axis of the connector 114 so that it is inserted into the fluid line connector 112 and the two are axially aligned. When overlapped, it serves to represent the corresponding axial cross-section of the connector 114. Although not required in all embodiments, the first and second bar schematics 200, 202 are based on the assumption that the retainer 129 is initially in its first use position. In this embodiment, along the first axial insertion depth 204 (or initial axial insertion depth) of the connector 114 into the fluid line connector 112, the first switch 134 should be in the open state. Along the first axial insertion depth 206 where the connector 114 is inserted into the fluid line connector 112, the second switch 135 may be in a closed state. Additionally, along the second axial insertion depth 208 (or intermediate axial insertion depth), the state of the first switch 134 may be uncertain, and the first switch 134 may be in a closed state. As shown, at the second axial insertion depth 208, the retainer 129 is now engaged with the ramp 119 and the appendage 183 of the first actuator member 136 is connected to the ramp 119 or extension. It is accessed by part 115. Along the second axial insertion depth 209, the second switch 135 may be in an uncertain state or closed. Along the third axial insertion depth 210, the second switch 135 should be in the open state. Here again, ramp 119 engages retainer 129 at a second axial insertion depth 210 . Finally, along the third axial insertion depth 212 (or final axial insertion depth), the first switch 134 should be in the closed state. And along the fourth axial insertion depth 214, the second switch 135 must also be in the closed state. At the third and fourth axial insertion depths 212 and 214, the first and second legs 169 and 171 are received in the slots 117 and the fluid line connector 112 and connector 114 are fully secured together. . Additionally, the first and second actuator members 136, 137 are actuated to impinge on the first and second switches 134, 135 at the third and fourth axial insertion depths 212, 214. Depending on the insertion movement of the connector 114 into the fluid line connector 112, in this embodiment, the first switch 134 goes from an open state, to an uncertain state, and to a closed state; The second switch 135 goes from a closed state, to an uncertain state, to an open state, and then back to a closed state. In a sense, the second switch 135 acts like a momentary switch and is in the closed state only when struck by the second actuator member 137. Moreover, when the first switch 134 initially enters the closed state (or at least may remain closed) at the second axial insertion depth 208, the second switch 135 simultaneously enters the closed state at the third axial insertion depth 210. ) in the open state, so false-negative detection readings are excluded. In other words, at least one of the first or second switches 134 and 135 remains open until the third and fourth axial insertion depths 212 and 214.

Still further alternatives to the embodiments of FIGS. 5 to 11 are possible. In one alternative, a collision from the first and second actuator members 136, 137 changes the state of each of the first and second switches 134, 135 - for example, causing the switch to initially open through the collision. either from a closed state and later to a closed state, or conversely, a collision brings the switch first from a closed state and later into an open state. In another alternative, the first switch 134 is itself an abutment from the connector 114 with the first actuator member 136 being indirectly actuated and moved indirectly by the abutment through the first switch 134. can be accepted.

Referring now to Figures 12 and 13, another embodiment of a fluid line connector and assembly 310 is presented. This embodiment has some similarities to the embodiments of FIGS. 1-4 and 5-11, which similarities may not be repeated in the description of the embodiments of FIGS. 12 and 13. The fluid line connector and assembly 310 includes a fluid line connector 312 and another separate, separate connector 314. The fluid line connector 312 has a quick connect function ready for connection and disconnection operations with connector 314 and is used to connect together automotive fluid lines as well as other fluid lines in other applications. . In this embodiment, the fluid line connector 312 is a female connector and the connector 314 is a male connector (often referred to as a spigot). Fluid line connector 312 accommodates insertion of connector 14, as shown in FIGS. 12 and 13. The fluid line connector 312 has an elbow and L-shaped configuration in the drawing, but may have a straight and in-line configuration in other embodiments. . The connector 314 may be an integral and somewhat monolithic part of a larger component, such as a vehicle battery tray or heat exchanger, or an integral and somewhat monolithic part of a fluid line, among many possibilities. It may be a part.

Referring particularly to Figure 13, the connector 314 in this embodiment has a ramp 319 and a slot 317. The ramp 319 is located at a distance from the terminal end 321 but is closer to the terminal end 321 than the slot 317. The ramp 319 forms an increasing diameter in the outer part of the connector 314. The slot 317 accommodates insertion of a retainer of fluid line connector 312, as described below. The slot 317 extends circumferentially around the connector 314.

The fluid line connector 312 may have a variety of designs, structures, and components in different embodiments. 12 and 13, the fluid line connector 312 includes a body 326, a cover 342, a retainer 329, a radio frequency identification (RFID) tag 332, a switch 334, and comprising an actuator member (336); Additionally, in other embodiments, fluid line connector 312 may have more, fewer, and/or other components. 13 in particular, body 326 has passages 338 defined in its structure to allow fluid flow through fluid line connector 312. The insert assembly may be provided within the fluid line connector 312 and within the passageway 338. Depending on its design and construction, the insert assembly may facilitate fitting, receiving and/or sealing between fluid line connector 312 and connector 314. In this embodiment, the insert assembly includes an O-ring (345). Additionally, the body 326 is configured to cooperate with the retainer 329 to provide a quick connection function for the fluid line connector 312. Referring to FIG. 12 , a first opening 349 and a second opening (not visible) are formed on opposing walls of the body wall and completely pass through it to connect to a passage 338 . Outside the wall, a first recess 353 and a second recess (again not visible) exist for temporary placement of retainer 329. Flange 357 protrudes radially outward from the body wall and when received in slot 317 partially seals sections of retainer 329 to prevent it from being inadvertently removed. To accommodate the use of the actuator member 336, a penetration 344 is defined in the wall of the body and extends completely therethrough to a passageway 338. The actuator member 336 is accessible in passage 338 through penetration 344. The actuator member 336 is located in and moves through the penetration 344. As shown in FIG. 13 , the penetrating portion 344 is positioned in the body 326 to receive insertion of the connector 314 to allow the actuator member 336 to interact with the connector 314, as described below. It is located near the end of.

The cover 342 is mounted on the body 326 and partially or more covers the RFID tag 332 to protect the RFID tag 332 from exposure to external objects and objects while using the fluid line connector 312. surround it The cover 342 may have various designs and structures. In this embodiment, when in place, the cover 342 is located on the outer border of the body 326 and completely surrounds the RFID tag 332. For attachment to the body 326, the cover 342 has a pair of devices disposed on each side of the structure that snap over the interconnecting structures on the body 326 and thereby establish its attachment. It has an extension 343 (only one is visible in Figure 12). Additionally, as explained below, the actuator member 336 is a monolithic component of the cover 342 in the embodiment presented herein. The actuator member 336 extends integrally from the front end 345 of the cover 342. Here, the actuator member 336 extends from the outer periphery 347 of the cover 342. This structure facilitates assembly and installation of the actuator member 336 when it is mounted on the cover 342 and received in the penetration portion 344 upon attachment of the cover 342 and the body 326. Additionally, in other embodiments the cover 342 and actuator member 336 need not represent the monolithic configuration described herein.

The retainer 329 interacts with the body 326 to provide quick connection functionality for the fluid line connector 312 so that the connector 314 can be easily inserted and retained in the fluid line connector 312 as required or desired. It allows it to be released and removed from it. The retainer 329 may have various designs and configurations. Referring particularly to Figure 12, in this embodiment retainer 329 is an inwardly biased, one-piece stainless steel wire spring. The retainer 329 has a first leg 369, a second leg (not visible), and a bridge 373 spanning between the legs. The first and second legs 369 may be substantially similar in shape and size. In the first use position, the retainer 329 is mounted on the body 326 with the first and second legs 369 moved through the first and second openings 349. First and second legs 369 are partially within passageway 338. In the first use position, the connector 314 is not inserted into the fluid line connector 312. In the second use position, connector 314 is in the process of being inserted into fluid line connector 312 and ramp 319 is engaged with first and second legs 369. The engagement forces the first and second legs 369 to spread apart from each other (i.e., radially outward) and may move the bridge 373 radially outward. As insertion of the connector 314 continues, the retainer 329 is moved to the third use position or fixed position where the retainer 329 is received in the slot 317. A third use position is shown in Figures 12 and 13. The first and second legs 369 can be snapped back to their positions in the first use position over the ramp 319 but are now received in the slots 317. The first and second legs 369 are moved through the first and second openings 349, respectively. Receiving first and second legs 369 in slots 317 secures fluid line connector 312 and connector 314 together. Movement of retainer 329 between its first, second and third use positions is approximately transverse to insertion direction 379 (FIG. 13) of connector 314 into fluid line connector 312. Move the retainer 329 in an orthogonal direction - that is, the movement of the retainer is generally radially outward, radially inward, or up and down. As the servicer pulls the retainer 129 up to release and remove the connector 114 from the fluid line connector 112, the terminal foot 173 (FIG. 9) of the first leg 169 1 may be seated in the recess 153, and similarly, the terminal foot (not specifically shown) of the second leg 171 may be seated in the second recess 155.

The RFID tag 332 assists in detecting proper and complete fixation between fluid line connector 312 and connector 314. RFID tag 332 communicates with RFID interrogator or reader 356 (FIG. 12). RFID interrogator 356 transmits an interrogating signal 358 to RFID tag 332, which in turn communicates with RFID interrogator 356. In this way, proper and complete stationary detection is performed using RFID technology. For example, in a manufacturing facility, RFID interrogators 356 may be located in the middle of an assembly, inspection, and/or installation production line, while fluid line connectors and assemblies 310 and larger applications may be transported through a holding area. When enabled, the RFID interrogator 356 may form an interrogation zone seeking to communicate with the RFID tag 332. Depending on the manufacturing facility, RFID interrogator 356 may form an interrogation zone spanning several meters from RFID interrogator 356. In another setting, or just another example, RFID interrogator 356 may be a mobile device, such as a handheld device.

The RFID tag 332 is a passive RFID tag type in this embodiment, but may be another type such as an active RFID tag. Communications received from the RFID tag 332 may convey various data and information to the RFID interrogator 356. In one embodiment, the information conveyed may be an indication of a secure state between fluid line connector 312 and connector 314. For example, when fluid line connector 312 and connector 314 indicate fully locked, RFID tag 332 may convey fully locked information in the form of an ON signal to RFID interrogator 356. And conversely, when the fluid line connector 312 and connector 314 are not completely secured, the RFID tag 332 may transmit less fully secured information to the RFID reader 356 in the form of an OFF signal. The RFID reader 356 can sequentially process the transmitted information. Information conveyed may also include part serial number, installation location, installation date, etc.

The RFID tag 332 is mounted on the main body 326. Support between the RFID tag 332 and the main body 326 can be achieved in various ways. In this embodiment, the RFID tag 332 is seated on the outer border of the main body and is protected by a cover 342 when installed. In this position, the RFID tag 332 is protected from external sources of contamination and away from exposure to fluid flows traveling through passageway 338 along the specific application. The RFID tag 332 may have a design similar to that shown in FIG. 11 and thus may have an antenna and an integrated circuit (IC) that stores data and information, among other possible functions. The antenna and IC may be located on the substrate of the RFID tag 332. Of course, the RFID tag 332 may have a different design than that of FIG. 11 .

Now returning to Figure 13, the switch 334 is connected to the RFID tag 332 to communicate its state to the RFID tag 332 based on collision or non-collision of the switch 334 by the actuator member 336. is electrically coupled to Electrical coupling may be in the form of wiring. In this embodiment, switch 334 is mounted directly on and carried by RFID tag 332. The switch 334 is carried into position on the RFID tag 332, so that upon assembly, the switch 334 is physically sandwiched by the actuator member 336 as shown in FIG. 13. In the direction of FIG. 13, the switch 334 is located on the underside of the RFID tag 332. The switch 334 may take a variety of forms in various embodiments, and in some cases may be determined by the design and configuration of the RFID tag and accompanying actuator member with which it interacts. In Figure 13, switch 334 is in the form of button 366. When physically pressed and struck by actuator member 336, button 366 is in the closed state. And button 366 is in the open state if it is not struck and physically depressed by actuator member 336.

The actuator member 336 serves to impinge on the switch 334 to change its state (e.g., from open to closed, or vice versa) when activated. In this embodiment, the actuator member 336 has only two operations occurring: a) inserting the connector 314 into the fluid line connector 312, and b) moving the retainer 329 into a fixed position. Only when moving, switch 334 is activated and collided. If either of these two actions is lacking, the actuator member 336 remains in an inoperative state and the switch is not struck. Actuator member 336 may have a variety of designs, structures, and components in different embodiments, which may in some cases depend on the design and components of the particular switch and connector. 12 and 13, actuator member 336 is an integral extension of cover 342, as previously described. The actuator member 336 is received in the penetrating portion 344 during assembly and installation, as shown in FIG. 13 . In this position, actuator member 336 is partially suspended within passageway 338 to receive mating from connector 314 during insertion of connector 314 into fluid line connector 312 and retainer 329. ) is partially exposed to the outside of the main body 326 to accommodate the joint. The actuator member 336 is located near the entrance 363 of the passageway 338. The longitudinal extent 377 of the actuator member 336 is arranged approximately in-line with the insertion direction 379.

In this embodiment, the actuator member 336 has a base 381 and an appendage 383 suspended from the base 381. Typically, the base 381 is located outside the passageway 338 and faces the retainer 329, while the appendage 383 is located in the passageway 338 and partially suspended therein and faces the connector 314. . With respect to the switch 334, the base 381 is located radially outward, and the appendage 383 is located radially inward opposite it. In this manner, switch 334 is sandwiched by actuator member 336, which can depress switch 334 on each side. Base 381 extends directly from cover 342 and appendage 383 extends directly from base 381.

The first extension 385 joins the cover 342 and the base 381, and the second extension 387 joins the base 381 and the appendage 383. The second extension 387 has a curved portion therein, wraps the actuator member 336 above and around the edge of the RFID tag 332, and is attached below the base 381 based on the direction of FIG. 13. Position (383). Opposite the second extension 387, the appendage 383 has a terminal and a free end 388 (Figure 13). The base 381 has a first operating surface 389 directly facing the retainer 329 for bonding thereto, and the appendage 383 has a second operating surface 391 facing the connector 314 for bonding thereto. ) has. The first operating surface 389 faces approximately radially outward and the second operating surface 391 faces approximately radially inward. First operating surface 389 receives a bond from retainer 329 and second operating surface 391 receives a bond from connector 314 . A curved seat 393 (FIG. 13) is attached to the base 381 to receive and cradle the bridge 373 of the retainer 329 when the retainer 329 is moved to its fixed position. exist. And opposite the second actuating surface 391, the appendage 383 has an inner actuating surface 392 that generally faces the switch 334 for direct impact thereon.

The actuator member 336 experiences movement during insertion of the connector 314 into the fluid line connector 312 and securing the retainer 329, as described further below. To facilitate movement of the actuator member, the first hinge end 395 is located on the first extension 385 and the second hinge end 397 is located on the second extension 387. In this embodiment, first hinge end 395 is a thin wall section compared to the thickness of the immediately surrounding wall sections. First hinge end 395 defines first axis 399 (FIG. 12). Part of the movement of the actuator member may include the base 381 being biased and displaced about the first hinge end 395 and about the first axis 399 relative to the cover 342 . Similar to first hinge end 395, second hinge end 397 defines second axis 401 (FIG. 12). Another portion of the movement of the actuator member may involve the appendage 383 being biased and displaced about the second axis 401 and about the second hinge end 397 relative to the base 381 . The first axis 399 and the second axis 401 are parallel to each other in this embodiment and are arranged to be approximately orthogonal to the insertion direction 379.

12 and 13, the actuator member 336 will actuate and strike the switch 334 only if there is agreement on the following: i) Connecting the connector 314 to the fluid line connector 312; complete and maximum possible insertion, and ii) definitive and complete movement of the retainer 329 to its fixed position. The conditions i) and ii) above are shown in FIGS. 12 and 13. If one of the two conditions i) or ii) is absent, or both conditions i) and ii) are absent, the actuator member 336 is not actuated and the switch 334 is not struck. Accordingly, switch 334 will change its state only when conditions i) and ii) are both met, and fluid line connector 312 will eventually exhibit proper, complete locking only when conditions i) and ii) are both met. will be. As demonstrated and unlike previous approaches, fluid line connector 312 enables detection of two conditions - the condition of connector 314 [i.e., i)] and the condition of retainer 329 [i.e., ii)]. utilizes the use of a single switch and a single actuator element to provide

During use of the fluid line connector 312, the connector 314 is inserted into the fluid line connector 312 and the lamp 319 is brought into contact with the appendage 383. The second operating surface 391 is in direct contact with the external surface of the lamp. A first force is applied from the ramp 319 to the appendage 383. The first force lies approximately transverse to the insertion direction 379. In response, when connector 314 reaches full insertion depth, as shown in FIG. 13 , both appendage 383 and base 381 may experience some degree of movement - retainer 329 Unless in its fixed position, movement of appendage 383 and base 381 does not result in collision of switch 334. The appendage 383 moves along an arcuate path relative to the base 381 and around the second axis 401 . On the other hand, base 381 moves slightly outward relative to cover 342 and about first axis 401 in response to movement of the appendage. Movement of the base 381 occurs and, in a sense, is allowed because there is no retainer 329 in its fixed position. In fact, it is the movement of the base 381 that prevents the switch 334 from colliding. When the retainer 329 moves to its fixed position and the leg 369 is received in the slot 317, the retainer 329 abuts the base 381. The first operating surface 389 is in direct contact with the outer surface of the bridge 373 of the retainer. A second force is applied from the retainer 329 to the base 381. Like the first force, the second force is approximately across the insertion direction 379. The second force has a direction approximately opposite to the first force. In this regard, the first force and the second force act as forces that react and oppose each other. In response, base 381 moves inward relative to cover 342 and relative to first axis 401 and to a position best shown in FIG. 13 . This movement and the opposing action of the first and second forces bring the actuator member 336 into its actuated state and the actuator member 336 impinges on and depresses the switch 334 . Impact of switch 334 is a result of being sandwiched between base 381 and appendage 383 and between first and second forces.

Referring now to Figures 14-16, another embodiment of a fluid line connector and assembly 410 is presented. This embodiment has some similarities to the previous embodiments of Figures 1-13, and the similarities may not be repeated in the description of the embodiment of Figures 14-16. Fluid line connector and assembly 410 includes fluid line connector 412 and other separate, individual connectors. The fluid line connector 412 has a quick connect function ready for connecting and disconnecting operations with individual connectors and is used to connect automotive fluid lines together as well as other fluid lines in other applications. do. For example, in an automotive fluid line application, fluid line connector 412 may be equipped with coolant fluid lines in an electric vehicle battery installation or in an automobile where fluid line connector 412 is not accessible after installation, among other possibilities. It may be provided inside a tank inside the fuel tanks. In in-tank applications, subsequent servicing of fluid line connector 412 can be difficult and often costly due to its internal location. 14-16, fluid line connector 412 is a female connector and the individual connectors are male connectors (sometimes referred to as spigots). Fluid line connector 412 accommodates insertion of individual connectors. The fluid line connector 412 has an elbow and L-shaped configuration in the figure, but may have a straight and in-line configuration in other embodiments. Individual connectors can be an integral and somewhat monolithic part of a larger component, such as a vehicle battery tray or heat exchanger, or they can be an integral and somewhat monolithic part of a fluid line, among many possibilities. there is.

The individual connectors of this embodiment may be similar to connector 14 described with reference to FIGS. 2 and 4 . Accordingly, an individual connector may have a first flange projecting outward in a radial direction of its body and a second flange projecting outwardly in a radial direction of its body. The first and second flanges may be axially spaced from each other and may span circumferentially around the individual connector.

The fluid line connector 412 may have a variety of designs, structures, and components in various embodiments. 14-16, the fluid line connector 412 includes a body 426, an O-ring 428, an insert 430, a radio frequency identification (RFID) tag 432, and an actuator member 436. ) includes. Additionally, in other embodiments, fluid line connector 412 may have more, fewer, and/or other components; For example, fluid line connector 412 need not have the O-ring 428 and insert 430 shown herein, but could have inserts of other designs and constructions, fit in different ways, and/or There may be another insert assembly to facilitate receiving and/or sealing, or there may be no need to have one or both of these components at all. 14 in particular, body 426 has passages 438 defined in its structure to allow fluid flow through fluid line connector 412. The passageway 438 constitutes the main and main passageway of the fluid line connector 412. The body 426 also has a compartment 440 for receiving and placing the RFID tag 432. The compartment 440 is a space separated from the passage 438. A removable cover 442 may be provided to close the compartment 440 and enclose the RFID tag 432 therein. Housing and placement of RFID tag 432 may have different designs and structures in other embodiments, including embodiments described elsewhere in this patent application.

The main body 426 further has a penetration portion 444 for positioning and seating the actuator member 436 within the main body 426 during assembly. When the actuator member 436 is not assembled to the penetration 444, the passage 438 and the compartment 440 communicate with each other through the penetration 444, which is open to both the passage 438 and the compartment 440. . The penetrating portion 444 extends axially between passage 438 and compartment 440, as shown in part in dashed lines in FIG. 14. The O-ring 428 is received within the passageway 438 and forms a seal between the fluid line connector 412 and the individual connector. The insert 430 is also received within passageway 438 and is used to help retain the individual connectors and fluid line connectors 412 when they are fastened together. In the example of FIG. 14 , insert 430 includes a pair of tangs 446 with hook ends 448 that capture the first flange to a sufficient depth of overlap when the individual connector is inserted into fluid line connector 412. have The insert 430 includes a first ring structure 450 and a second ring structure 452 connected together by tangs 446. The press downs 454 on the opposite side of the second ring structure 452 can be pressed to release and release the captured first flange for disassembly of the individual connector from the fluid line connector 412.

The RFID tag 432 assists in detecting proper and complete locking between the fluid line connector 412 and the individual connector. RFID tag 432 communicates with RFID interrogator or reader 456 (FIG. 14). RFID interrogator 456 transmits an interrogating signal 458 to RFID tag 432, which in turn can communicate with RFID interrogator 456. In this way, proper and complete stationary detection is performed using RFID technology. For example, in a manufacturing facility, RFID interrogator 456 may be located in the middle of an assembly, inspection, and/or installation production line, while fluid line connectors and assemblies 410 and larger applications may be transported through a holding area. As a result, the RFID interrogator 456 may form an interrogation zone in which the RFID chip 432 and the RFID chip 432 attempt to communicate with each other. Depending on the manufacturing facility, RFID interrogator 456 may form an interrogation zone that extends several meters from RFID interrogator 456. In another setting, or just another example, RFID interrogator 456 may be a mobile device, such as a handheld device.

The RFID tag 432 is a passive RFID tag type in this embodiment, but may also be of other types, such as an active RFID tag. Communications received from the RFID tag 432 may convey various data and information to the RFID interrogator 456. In one embodiment, the information may be an indication of a secure state between the fluid line connector 412 and the individual connector. For example, when the fluid line connector 412 and the individual connectors indicate fully locked, the RFID tag 432 may convey fully locked information to the RFID interrogator 456 in the form of an ON signal. And, conversely, when the fluid line connector 412 and the individual connectors are less fully secured, the information that is less fully secured may result in the absence of a signal from the RFID tag 432 to the RFID interrogator 456 or a loss of signal from the RFID tag 432. This can be identified in the form of silence, or the RFID tag 432 transmits less completely static information to the RFID interrogator 456 in the form of an OFF signal. These are simple examples of how to indicate a secure state between the fluid line connector 412 and the individual connector; Other examples are possible in other embodiments. The RFID interrogator 456 can process information sequentially. The information may also include part serial number, installation location, installation date, etc.

The RFID tag 432 is mounted on the main body 426 in this embodiment, or at least located near the main body 426. Support between RFID tag 432 and body 426 can be effected in a variety of ways. In this embodiment, RFID tag 432 resides within compartment 440 and is protected by cover 442 when installed. In this position, the RFID tag 432 is protected from exposure to fluid flows moving through passageway 438 and is protected from external sources of contamination, depending on the particular application. Referring now to Figure 15, RFID tag 432 has a substrate 423 and circuitry 464 in the form of an integrated circuit for storing data and information, among other possible functions. Circuit 464 is disposed on substrate 423. Circuit 464 includes circuit paths 425 established by conductive traces 427 arranged on substrate 423. Conductive trace 427 may be comprised of copper in the example. Current may flow over circuit path 425 through conductive trace 427. Break 431 of circuit 464 prevents the continuation of current flow in circuit path 425. Brake 431 may be designed and configured in various ways. 15, the break 431 is formed by a discontinuity 433 in the circuit path 425. Discontinuities 433 interrupt the continuity of current flow in circuit path 425. Here, circuit path 425 terminates at a first circuit path end 435 at one location and at a second circuit path end 437 at another location. The first and second circuit path ends 435, 437 are located close together and face each other across the gap defined by discontinuity 433. The discontinuity 433 is formed through the first and second circuit path ends 435 and 437. The first and second circuit path ends 435, 437 may be comprised of a conductive ink, such as a conductive carbon ink according to one example, may be comprised of a copper pad according to another example, or may be comprised of something else. You can. Continuing, RFID tag 432 may have more, fewer, and/or different circuit components than those presented herein; Its exact components may be determined by the intended function of the RFID tag 432.

The actuator member 436 receives the abutment during full locking operation and at full locking between the fluid line connector 412 and the individual connector. Actuator member 436 may have a variety of designs, structures, and components in different embodiments, in some cases depending on the design and configuration of body 426, RFID tag 432, and/or individual connectors. . In this embodiment, referring now to FIGS. 14 and 16 , actuator member 436 extends between passageway 438 and RFID tag 432 and provides interrelationship between individual connectors and RFID tag 432. do. The actuator member 436, when assembled, is carried within the body 426 of the fluid line connector 412 and is positioned and seated in the penetration portion 444. In its assembled position, actuator member 436 has one end at passageway 438 and the other end at RFID tag 432. In this embodiment, the actuator member 436 is in the form of a cam member 472. Cam member 472 is one-piece and has an approximately U-shaped profile. The cam member 472 has a base portion 474 and a pair of prong portions 476 dependent on the base portion 474. When the cam member 472 is positioned in the penetration portion 444, the base portion 474 directly faces and opposes the RFID tag 432 across the gap formed therebetween, particularly the first and second circuit paths. At ends 435, 437 they face and oppose circuit path 425. In Figure 16, the base portion 474 is shown as having a slightly arcuate shape. However, base portion 474 may have different designs, structures, and shapes in other embodiments to facilitate bridging of brake 431 during use of fluid line connector 412. For example, base portion 474 may have a flatter, less arched shape than that shown in FIG. 16 . Indeed, in some embodiments, projections or protrusions on each side of base portion 474 may extend upwardly from base portion 474 in opposite directions of prong portions 476; Here the protrusions/projections can more easily contact the circuit 464 for connection purposes.

The prong portions 476 include a first prong portion 475 and a second prong portion 477 . The first and second prong portions 475, 477 have an operating surface 480 that defines adjacent terminal ends of the first and second prong portions 475, 477, respectively. When assembled, the actuating surfaces 480 remain partially or more suspended in the passageway 438 available for mating by the individual connectors when inserting the individual connectors into the fluid line connector 12. To facilitate mating with the individual connector, the actuating surface 480 may be inclined upward toward the base portion 474 and about the major longitudinal axis of the individual connector.

In order to bridge the brake 431 and achieve continuity at the discontinuity 433, the actuator element 436 has an actuating part 481 made of electrically conductive material. When the actuating portion 481 engages the brake 431, as described in more detail below, current flows through the actuating portion 481 and its electrically conductive configuration into the first and second circuit paths of circuit path 425. It can flow and transmit between the ends 435 and 437 and can be electrically transmitted. Once connected, current can travel from the first circuit path end 435 through the actuating portion 481 to the second circuit path end 437 and vice versa. The electrically conductive material may be copper, graphite, silver or carbon particles, or other conductive material, depending on the embodiment. When the actuator member 436 is positioned in the penetrating portion 44 and is in an unactuated state and position, the actuating portion 481 crosses the gap formed therebetween to connect the circuit 464 of the RFID tag 432. ) faces.

The actuating portion 481 may take different forms in different embodiments. In one embodiment, actuating portion 481 consists of actuating surface 483 of actuator member 436. Operating surface 483 is the exterior and outboard surface of base portion 474. The operating surfaces 483 directly and immediately face and oppose the first circuit path ends 435, 437. For current flow through the operating surface 483, a conductive ink 485 is applied and present on one or more portions of the operating surface 483 (the conductive ink 485 is indicated by the depiction in FIG. 16 surrounded by a dashed line). The above depiction and dashed lines are not necessarily intended to suggest the exact arrangement of the conductive ink 485 applied to the operating surface 483, but are instead shown for illustrative purposes). The conductive ink 485 may be conductive carbon ink, conductive graphite ink, etc. In this embodiment, other parts of the actuator member 436 may be composed of a material different from that of the conductive ink 485 at the operating surface 483; For example, the base portion 474 and prong portions 476 may be comprised of a plastic material or an electrically non-conductive material. Current flow may then occur only through the conductive ink 485 and not in other areas of the base portion 474 and the prongs 476 . In other embodiments, the actuating portion 481 consists of part or more of the base portion 474. For example, the entire base part 474 could be the working part 481 and thus the entire base part 474 could be composed of an electrically conductive material (this possibility is indicated by reference numeral 487 in Figure 16 ; As before, the depictions and dashed lines are for illustrative purposes.In another example of this embodiment, the layer of the base portion 474 may be the operative portion 481 and thus the layer may be comprised of an electrically conductive material. The layer has a thickness and depth greater than a simple surface.In this embodiment and these examples, other portions of the actuator member 436 may be comprised of a material different from that of the electrically conductive material; for example, the prong portion Other parts, such as the prongs 476, may be constructed of a plastic material or an electrically non-conductive material, so that current flow can only occur through the electrically conductive material, regardless of configuration, and other parts, such as the prongs 476. This may not occur in the region.Continued, in another embodiment the actuating portion 481 is comprised entirely of the actuator member 436 and thus the entire actuator member 436 is comprised of an electrically conductive material.

Additionally, unlike the first embodiment of the fluid line connector of FIGS. 1 to 4, the embodiment of fluid line connector 412 of FIGS. 14 to 16 is not provided with a switch component in the RFID tag 432. No switch components are interposed between the actuator member 436 and the RFID tag 432. Rather, the actuator member 436 and its actuating portion 481 have a direct and immediate coupling path and interact with the RFID tag 432 without a switch component or any other components in between.

When the fluid line connector and assembly 410 is in use, proper and complete fixation can be detected via RFID technology. The fluid line connector 412 and the individual connectors are joined together by inserting the individual connectors into the body 426 and the passageway 438. The first flange of the individual connector contacts the actuator member 436 (i.e., the cam member 472 in this embodiment) upon insertion. The cam member 472 is in an inoperative state and position prior to engagement. In its non-actuated state and position, the cam member 472 is spaced apart from the RFID tag 432 and is not in contact with the RFID tag 432 and is not in contact with the circuitry 464. The break 431 is not connected and continuity is not affected by the discontinuity 433. When there is no such contact and the cam member 472 is in an inactive state and position, depending on the embodiment, the RFID tag 432 and RFID interrogator 456 become unable to communicate with each other. The absence of communication and the resulting silence of the RFID tag 432 serves as an indication that the fluid line connector 412 and the individual connectors lack complete retention. In another embodiment, when the cam member 472 is in an inoperative state and position and there is a lack of contact between the cam member 472 and the RFID tag 432, the RFID tag 432 sends an OFF signal to the RFID interrogator ( 456). The OFF signal serves as an indication that the fluid line connector 412 and the individual connectors lack complete locking.

The first flange of the respective connector, upon insertion, forms a surface-to-surface abutment with the actuating surface 480 of the cam member 472. The cam member 472 is displaced and promoted to move upward in a first direction approximately transverse and perpendicular to the second direction of the passageway 438. Fluid flows through passage 438 adjacent cam member 472 in a second direction; Additionally, the individual connectors are inserted into the fluid line connector 412 in the second direction. The cam member 472 is in surface-to-surface contact with the RFID tag 432 and the circuit 464. Here, the cam member 472 is in an operational state and position. The actuating portion 481 is in direct and immediate contact with the circuit path 425, without any intervening components therebetween. In particular, the actuating portion 481 is in direct and immediate contact with the first circuit path end 435 and the second circuit path end 437. The exterior and outboard surfaces of the base portion 474 contact the exterior surfaces of the first and second circuit path ends 435. Accordingly, the brake 431 is connected and contacted through the operating part 481, and the continuity is affected by the discontinuity 433. Current can now travel from the first circuit path end 435, through the actuating portion 481, and to the second circuit path end 437, and vice versa. The RFID tag 432 and the RFID interrogator 456, depending on the embodiment, are enabled to communicate with each other when the cam member 472 is in an actuated state and position and when contact is made. The communication capability can serve as an indication that the fluid line connector 412 and the individual connectors are fully secured. In one example, RFID tag 432 transmits an ON signal to RFID interrogator 456. The ON signal may serve as an indication that the fluid line connector 412 and the individual connectors are fully fixed. According to an embodiment, movement of the actuator member 436 from its non-actuated position to its activated position facilitates a change of state of the RFID tag 432. The change in state of the RFID tag 432 - from the first state to the second state - serves as an indication that the fluid line connector 412 and the individual connectors have reached full locking.
