Abstract

The fluid line connectors provide remote stationary detection capability and are thus equipped for initial assembly, subsequent quality inspection, and subsequent service techniques, which may be automated, robotic, and/or autonomous. In one embodiment, a fluid line connector includes a body, a Radio Frequency Identification (RFID) tag, and an actuator member. The body has a passage through which a fluid flows. The RFID tag may be in communication with an RFID interrogator and have a circuit with a circuit break in the circuit. One or more portions (e.g., surfaces) of the actuator member are composed of an electrically conductive material. When the actuator member is actuated, the conductive portion bridges the circuit break.

Technical Field

The present invention relates generally to connector assemblies for connecting fluid lines together, and more particularly to a method of detecting proper and complete engagement of connector assembly components.

Background

Connector assemblies, particularly those having a quick connect function, are commonly used to connect fluid lines together in vehicle applications. One example is a coolant fluid line in an electric vehicle. For initial assembly and inspection and subsequent repair, visual measurements are sometimes employed in the design and construction of the connector assembly to verify that proper and complete engagement has been made between the components of the connector assembly. Examples include auxiliary latches that close when fully engaged and windows built into one member of the connector assembly for viewing the engagement. These and other similar measures require physical interaction and observation by an assembler, inspector or serviceman to ensure that proper and complete engagement has been made between the components of the connector assembly.

Detailed Description

Various embodiments of fluid line connectors and assemblies are described in detail herein. The connectors and assemblies are designed and constructed to detect proper and complete securement between connectors without the need for past auxiliary latches and windows that require some degree of physical interaction and observation by an assembler, inspector or serviceman in a secured position. Instead, the connector and assembly of the present description is provided with means in which a correct and complete fixation can be detected via a device remote from the direct fixation position of the connector, and which does not require physical contact with the fixation position for detection. In this way, the connectors and components are equipped for automated, roboticized, and/or autonomous initial assembly, subsequent quality inspection, and subsequent service techniques (such as those found in advanced manufacturing facilities in automated production). Thus, connectors and components may prove useful in many applications (e.g., where no power is available off-the-shelf or at any time). The present description describes connectors and assemblies in the context of automotive fluid lines (e.g., coolant fluid lines in electric vehicles), but connectors and assemblies have broader application and are applicable to aircraft fluid lines, marine fluid lines, agricultural fluid lines, and other fluid lines.

As used herein, the phrase "fully secured" and grammatical variations thereof is used to refer to a secured state in which a fluid-tight connection is established via a fluid line connector. Furthermore, unless otherwise indicated, the terms "radial," "axial," and "circumferential," and grammatical variations thereof, refer to directions relative to the generally circular shape of a channel of a fluid line connector.

In different embodiments, the fluid line connectors and assemblies may have different designs, configurations, and components, depending in some cases on the application in which the fluid line connectors and assemblies are employed. Fig. 1-4 illustrate a first embodiment of a fluid line connector and assembly 10. The fluid line connector and assembly 10 includes a fluid line connector 12 and another separate and discrete connector 14. The fluid line connector 12 has a quick connect function, can be connected and disconnected from the connector 14 at any time, and is used to connect automatic fluid lines together. In this embodiment, the fluid line connector 12 is a female connector and the connector 14 is a male connector (commonly referred to as a ferrule). The fluid line connector 12 receives insertion of the connector 14 at a first end 16 and connects to the fluid line at a second end 18 when installed. In the figures, the fluid line connector 12 has a curved, L-shaped configuration, but may have a straight, in-line configuration in other embodiments. In many possibilities, the connector 14 may be an integral and somewhat unitary part of a larger component such as a vehicle battery tray or heat exchanger, or may be an integral and somewhat unitary part. Referring specifically to fig. 2 and 4, the connector 14 has a first flange 20 projecting radially outwardly from its body and has a second flange 22 axially spaced from the first flange 20 and likewise projecting radially outwardly from the connector body. The first and second flanges 20, 22 extend circumferentially around the connector 14. The connector 14 has an outer 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, a switch 34, and an actuator member 36; however, in other embodiments, the fluid line connector 12 may have more, fewer, and/or different components. Referring now to fig. 3 and 4, the body 26 has a passage 38 defined in its structure for allowing fluid flow through the fluid line connector 12. The body 26 also has a compartment 40 for receiving and placing the RFID chip 32. The compartment 40 is a space separate from the channel 38. A removable cover 42 may be provided to close compartment 40 and enclose RFID chip 32 therein. The body 26 also has a through-penetration 44 for positioning and seating the actuator member 36 within the body 26 when assembled. When the actuator member 36 is removed from the body 26 (e.g., as shown in fig. 3), the channel 38 and the compartment 40 communicate with each other through a through-penetration 44 that is open to both the channel 38 and the compartment 40. The O-ring 28 is received within the channel 38, as shown in fig. 4, and forms a seal between the fluid line connector 12 and the connector 14. When the connector 14 and the fluid line connector 12 are secured together, the insert 30 is also received within the channel 38 and serves to help retain the connector 14. In the example of the figures, the insert 30 has a pair of tangs 46 with hooked ends 48, the hooked ends 48 capturing the first flange 20 when the connector 14 is inserted into the fluid line connector 12 to the proper depth of overlap, as shown in fig. 4. The insert 30 includes a first annular structure 50 and a second annular structure 52 bridged together by the tang 46. The hold-down portions 54 on opposite sides of the second annular structure 52 may be pressed to release the captured first flange 20 to detach the connector 14 from the fluid line connector 12.

RFID chip 32 helps to detect proper and complete securement between fluid line connector 12 and connector 14. RFID chip 32 transmits and receives Radio Frequency (RF) signals using RFID interrogator 56.RFID interrogator 56 sends an interrogation signal 58 to RFID chip 32, and RFID chip 32 responds with an RF signal 60. In this way, a correct and complete stationary detection is achieved by using RFID technology. For example, in a manufacturing facility, RFID interrogator 56 may be located in an assembly, inspection, and/or installation line and an interrogation zone may be established in which RFID interrogator 56 attempts to communicate with RFID chip 32 as fluid line connectors and assemblies 10 and larger applications are transported through the fixed zone. Depending on the manufacturing facility, RFID interrogator 56 may establish an interrogation zone that spans several meters from RFID interrogator 56. In another arrangement, the RFID interrogator 56 may be a mobile device, such as a handheld device. The RF signal 60 may communicate various data and information to the RFID interrogator 56. In one embodiment, the information communicated may be an indication of the status of the securement between the fluid line connector 12 and the connector 14. For example, when fluid line connector 12 and connector 14 exhibit complete securement, RF signal 60 may transmit the complete securement to RFID interrogator 56 in the form of an ON signal. The RFID interrogator 56 may in turn process the transmitted information. The transmitted information may also include a serial number, installation location, etc.

Referring specifically to fig. 3 and 4, the rfid chip 32 is carried by the body 26. The support between the RFID chip 32 and the body 26 may be achieved in various ways. In this embodiment, RFID chip 32 is located within compartment 40 and is protected by cover 42 when installed. In this position, RFID chip 32 is shielded from exposure to fluid flow through channel 38 and shielded from external sources of contamination, depending on the particular application. 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.

Switch 34 interacts with RFID chip 32 to activate and enable RFID chip 32 to transmit and receive RF signals with RFID interrogator 56, and to deactivate and disable RFID chip 32 from transmitting and receiving RF signals. However, such interactions may otherwise affect the functionality of RFID chip 32. In the embodiment shown in the drawings, switch 34 is electrically coupled to RFID chip 32 to enable antenna 62 to transmit and receive RF signals and to disable antenna 62 from transmitting and receiving RF signals. In different embodiments, the switch 34 may have various designs, configurations, and components, depending in some cases on the design and configuration of the RFID chip and accompanying connector with which it interacts. For example, the switch 34 may take mechanical, electrical, and magnetic forms. In one embodiment, referring to fig. 3 and 4, switch 34 is in the form of a button 66 mounted on RFID chip 32. As best shown in fig. 4, the button 66 is located between the RFID chip 32 and the actuator member 36 and adjacent the through-penetration 44. When impacted and physically pressed, button 66 (due to its electrical coupling with RFID chip 32) activates and enables antenna 62 to transmit and receive RF signals. Depending on the embodiment, a single press and release of button 66 may activate RFID chip 32, or a sustained impact and press may activate RFID chip 32 for the duration of the impact and press. Conversely, a single press and release of button 66 may deactivate RFID chip 32, or no sustained impact and press may deactivate RFID chip 32 for the duration of no impact and press.

Moreover, in other embodiments, the switch 34 may be caused to activate and deactivate the RFID chip 32 by other means. Referring specifically to fig. 4, another embodiment performs prompting by using a non-contact switch instead of a contact-based switch. Reed switch 68 is carried by body 26 of fluid line connector 12 and magnetic member 70 is carried by connector 14. In this context, when fluid line connector 12 and connector 14 are fully secured, the proximity between reed switch 68 and magnetic member 70 facilitates activation of RFID chip 32. Conversely, incomplete fixation of reed switch 68 and magnetic component 70 relative to each other and the concomitant distance may deactivate RFID chip 32. In this embodiment, the actuator member 36 need not be provided.

The actuator member 36 receives abutment during and when fully secured between the fluid line connector 12 and the connector 14, thereby causing impact of the switch 34. In different embodiments, the actuator member 36 may have various designs, configurations, and components, depending in some cases on the design and configuration of the switch 34 and accompanying connectors. In the embodiment of the drawings, referring now to fig. 3 and 4, an actuator member 36 spans between the channel 38 and the switch 34 to provide the interrelationship between the connector 14 and the RFID chip 32. The actuator member 36 is carried within the body 26 of the fluid line connector 12 and is positioned and seated in the throughgoing member 44. In its position, the actuator member 36 has one end at the channel 38 and the other end at the switch 34. In the embodiment of fig. 3 and 4, the actuator member 36 is in the form of a cam member 72. The cam member 72 is unitary and has a U-shaped profile with a base portion 74 and a pair of tine portions 76 depending from the base portion 74. The base portion 74 has a first working surface 78 located at the switch 34 and maintained in contact with the switch 34. And each tine portion 76 has a second working surface 80 located in the channel 38 for abutment with the connector 14 when the connector 14 is inserted into the fluid line connector 12. The second working surface 80 may be inclined relative to the axis of the connector 14 so as to readily abut the connector 14 and cause a corresponding displacement of the cam member 72.

When using the fluid line connector and assembly 10, proper and complete securement may be detected via RFID technology. When the connector 14 is inserted into the body 26 at the first end 16, the fluid line connector 12 and the connector 14 are brought together. The first flange 20 abuts the cam member 72 and displaces the cam member 72 upwardly (relative to the orientation of the drawing) and toward the button 66. The first flange 20 is in face-to-face abutment with the second working surface 80 of the cam member 72. The cam member 72 is urged upwardly and impacts the button 66 via face-to-face contact between the first working surface 78 and the facing surface of the button 66. In this embodiment, the first flange 20 remains in abutment with the cam member 72, so the cam member 72 remains in a fully seated condition against the button 66.

In another embodiment, fluid line connector 12 includes more than one RFID chip. Referring specifically to fig. 3, a second RFID chip 33 is provided in addition to the first RFID chip 32. As with the first RFID chip 32, the second RFID chip 33 helps to detect proper and complete securement between the fluid line connector 12 and the connector 14. In this embodiment, both the first RFID chip 32 and the second RFID chip 33 transmit and receive RF signals with the RFID interrogator 56. In one example, when fluid line connector 12 and connector 14 exhibit complete securement, first RFID chip 32 may communicate the complete securement to RFID interrogator 56. Conversely, when fluid line connector 12 and connector 14 are not fully secured together, second RFID chip 33 may communicate such incomplete securing to RFID interrogator 56. Further, in the completely fixed state, the second RFID chip 33 does not transmit incompletely fixed information to the RFID interrogator 56; also, when not fully secured together, the first RFID chip 32 does not transmit fully secured information to the RFID interrogator 56. As in the previous embodiment, the first RFID chip 32 and the second RFID chip 33 may transmit additional information such as a serial number, an installation position, and the like. Whether the first RFID chip 32 transmits its fully fixed information or the second RFID chip 33 transmits its incompletely fixed information is partly managed by the switch 34. In this embodiment, the switch 34 interacts with both the first RFID chip 32 and the second RFID chip 33 and is electrically coupled to both the first RFID chip 32 and the second RFID chip 33. The interaction and transfer of information may be accomplished in different ways. For example, when impacted, the switch 34 may activate and enable the first RFID chip 32 to communicate fully immobilized information, while when not impacted, the switch 34 may activate and enable the second RFID chip 33 to communicate incompletely immobilized information. The impact of the switch 34 and the absence of the impact of the switch 34 may deactivate and disable the first RFID chip 32 or the second RFID chip 33.

Referring now to fig. 5-11, yet another embodiment of a fluid line connector and assembly 110 is shown. This embodiment has some similarities to the embodiment of fig. 1-4 and the similarities may not be repeated in the description of the embodiment of fig. 5-11. The fluid line connector and assembly 110 includes a fluid line connector 112 and another separate and discrete connector 114. The fluid line connector 112 has a quick connect function, can be readily connected and disconnected from the connector 114, and is used to connect automatic fluid lines together with other fluid lines in other applications. In this embodiment, the fluid line connector 112 is a female connector and the connector 114 is a male connector (commonly referred to as a ferrule). As shown in fig. 7, the fluid line connector 112 receives the insertion of the connector 114. In the figures, the fluid line connector 112 has a curved, L-shaped configuration, but may have a straight, in-line configuration in other embodiments. In many possibilities, the connector 114 may be an integral and somewhat unitary part of a larger component such as a vehicle battery tray or heat exchanger, or may be an integral and somewhat unitary part of a fluid circuit.

Referring specifically to fig. 6, connector 114 has an extension 115 and a slot 117 at one end of connector 114, and connector 114 is inserted into fluid line connector 112. Extension 115 may be received in 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, extension 115 may abut a first actuator member (described below) of fluid line connector 112, and thus may cause actuation thereof. When provided, the extension 115 axially spans the insertion end of the connector 114 and protrudes radially outward from the surrounding body of the connector. As described below, the slot 117 receives insertion of a retainer of the fluid line connector 112. Slots 117 circumferentially span connector 114. In addition, the connector 114 has a bevel 119. The diameter of the ramp 119 in the connector 114 increases gradually. The outer surface 113 is positioned from the slot 117 to the ramp 119. Before extension 115 and slot 117 are received in fluid line connector 112 (i.e., from right to left in the orientation of fig. 6), connector 114 is inserted into fluid line connector 112 with ramp 119 received in fluid line connector 112.

In the embodiment shown in fig. 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 one or two actuator members 136, 137; however, in other embodiments, the fluid line connector 112 may have more, fewer, and/or different components. Turning now to fig. 5 and 7-9, the body 126 has a passageway 138 defined in its structure for allowing fluid flow through the fluid line connector 112. In addition, the 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 shown only in fig. 5 and 7, but the description of fig. 8 and 9 may have a similar structure for housing the RFID tag 132). The cover 142 may be removable, although it is not required. Furthermore, although only partially shown in fig. 5, an insert assembly 143 may be disposed and carried within the interior of the fluid line connector 112 and within the channel 138. Depending on its design and configuration, the insert assembly 143 may facilitate mating, receiving, and/or sealing between the fluid line connector 112 and the connector 114. For example, depending on the embodiment, the insert assembly 143 may include an O-ring 145 and a carrier 147, and may also include a bushing.

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 fig. 5 and 7-9, a first opening 149 and a second opening 151 are defined on opposite sides of the body wall and span entirely through the body wall and open to the channel 138. On the outside of the wall there is a first recess 153 and a second recess 155 for temporarily deploying the retainer 129 when the retainer 129 is pulled radially outwardly to release the connector 114 from the fluid line connector 112. The flange 157 protrudes radially outward of the body wall and partially encloses a portion of the retainer 129 to prevent the retainer 129 from accidentally falling out when received in the slot 117.

Further, the body 126 has a structure intended to accommodate assembly and installation of the actuator members 136, 137. The precise design and configuration of the structure may vary and may depend on the design and configuration of the actuator components and switches used in the fluid line connector 112. In the embodiment shown in the drawings, turning now to fig. 5, 8 and 9, the first receptacle 159 and the second receptacle 161 are located in the body 126. The first receptacle 159 receives and retains the first actuator member 136 and in this embodiment is in the form of a slot arrangement. The first receptacle 159 is located at the inlet 163 of the channel 138 for placement of the first actuator member 136 thereat and is defined in the body wall adjacent the inlet 163. To fully receive the first actuator member 136, the axial depth of the first receptacle 159 may be approximately equal to the length of the first actuator member 136. Also, in a similar manner, the radial width of the first receptacle 159 may be substantially equal to the width of the first actuator member 136. The axial depth of the first receptacle 159 is generally aligned with the axis of the channel 138 at the inlet 163. The figures show an enlarged formation in the body wall to accommodate the first actuator member 136 and for providing the first receptacle 159, but in other embodiments the accommodating formation may be more coherent and integral with the body 126 so that the enlargement may be reduced as much as possible.

Referring now specifically to fig. 9, the second socket 161 receives and retains the second actuator member 137, and in this embodiment is in the form of a socket structure. The second socket 161 is located outside the channel 138 and on one side of the body wall for placing the second actuator member 137 there. To fully receive 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. Also, in a similar manner, the axial width of the second socket 161 may be substantially equal to the width of the second actuator member 137. The radial depth of the second socket 161 is substantially aligned with the radius of the channel 138 at the inlet 163. The figures show the enlarged formation protruding from the side of the body wall to accommodate the second actuator member 137 and for providing the second socket 161, but in other embodiments the accommodation formation may be more coherent and integral with the body 126 so that the enlarged formation may be reduced as much as possible. In fig. 9, bottom wall 165 and a pair of side walls 167 depending from bottom wall 165 together partially enclose second actuator member 137 and help prevent inadvertent contact of extraneous components when fluid line connector 112 is in use.

The retainer 129 interacts with the body 126 to provide a quick connect function of the fluid line connector 112 such that the connector 114 can be easily inserted and retained in the fluid line connector 112 and can be released and removed from the fluid line connector 112 as needed or desired. The retainer 129 may vary in design and construction. Referring specifically to fig. 5 and 8, in this embodiment, the retainer 129 is an inwardly biased integral stainless steel wire spring. The retainer 129 has a first leg 169, a second leg 171, and a bridge 173 spanning between the legs. The first leg 169 and the second leg 171 may be substantially similar in shape and size. A first use position of the retainer 129 is shown in fig. 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 moving through the first and second openings 149, 151. The first leg 169 and the second leg 171 are partially located within the channel 138. In the first use position, connector 114 is not inserted into fluid line connector 112. The second use position of the holder 129 is not specifically described in the figures. In the second use position, connector 114 is inserted into fluid line connector 112 and ramp 119 engages first leg 169 and second leg 171. This engagement urges the first leg 169 and the second leg 171 away from each other (i.e., radially outward) and may move the bridge 173 radially outward. As the connector 114 continues to be inserted, the retainer 129 is brought to a third use position in which the retainer 129 is received in the slot 117. The first leg 169 and the second leg 171 ride over the ramp 119 and can snap back to their first use position, but are now received in the slot 117. The first leg 169 and the second leg 171 move through the first opening and the second opening 149, respectively. One or both of the first leg 169 and the second leg 171 are received in the slot 117 to secure the fluid line connector 112 and the connector 114 together. Movement of the retainer 129 between its first, second and third use positions causes the retainer 129 to move in a direction generally transverse and orthogonal to the insertion direction 179 (fig. 5) of the connector 114 into the fluid line connector 112, in other words, the retainer movement is radially outward and radially inward, or up and down. When a serviceman pulls up on the retainer 129 to release and remove the connector 114 from the fluid line connector 112, a terminal foot 173 (fig. 9) of a first leg 169 may be disposed in the first recess 153, as well as a terminal foot (not specifically shown) of a second leg 171 may be disposed in the second recess 155.

Turning now to fig. 11, rfid tag 132 helps to detect proper and complete securement 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 interrogation signal 158 to the RFID tag 132, which in turn communicates with the RFID interrogator 156. In this way, a correct and complete stationary detection is achieved by using RFID technology. For example, in a manufacturing facility, RFID interrogator 156 may be located in an assembly, inspection, and/or installation line and an interrogation zone may be established in which RFID interrogator 156 attempts to communicate with RFID tag 132 as fluid line connectors and assemblies 110 and larger applications are transported through the fixed zone. Depending on the manufacturing facility, RFID interrogator 156 may establish an interrogation zone that spans several meters from RFID interrogator 156. In another arrangement, the RFID interrogator 156 may be a mobile device, such as a handheld device.

In this embodiment, RFID tag 132 is a passive RFID tag type, but may be another type, such as an active RFID tag. Communications received from the RFID tag 132 may convey various data and information to the RFID interrogator 156. In one embodiment, the information communicated may be an indication of the status of the securement between the fluid line connector 112 and the connector 114. For example, when fluid line connector 112 and connector 114 exhibit complete securement, RFID tag 132 may transmit the complete securement to RFID interrogator 156 in the form of an ON signal. Conversely, when fluid line connector 112 and connector 114 are not fully secured, RFID tag 132 may transmit the information of the not fully secured to RFID interrogator 156 in the form of an OFF signal. The RFID interrogator 156 may in turn process the transmitted information. The information transmitted may also include part serial number, installation location, etc. In embodiments where the fluid line connector 112 is equipped with switches 134, 135 and actuator members 136, 137, the RFID tag 132 may communicate the status of each actuator member 136, 137 based on the impact or non-impact of the switch 134, 135. For example, the RFID tag 132 may transmit one or more of the following information: i) Neither of the actuator members 136, 137 is actuated, and therefore both the first switch 134 and the second switch 135 are in an open state, ii) the first actuator member 136 is not actuated, and therefore the first switch 134 is in an open state, and the second actuator member 137 is actuated, and therefore the second switch 135 is in a closed state, iii) the first actuator member 136 is actuated, and therefore the first switch 134 is in a closed state, and the second actuator member 137 is not actuated, and therefore the second switch 135 is in an open state, and/or iv) both the first actuator member 136 and the second actuator member 137 are actuated, and therefore both the first switch 134 and the second switch 135 are in a closed state.

An RFID tag 132 is carried by the body 126. The support between the RFID tag 132 and the body 126 may be implemented in various ways. In this embodiment, the RFID tag 132 is located within a compartment of the body and is protected by a cover 142 when installed. In this position, the RFID tag 132 is shielded from exposure to fluid flow through the channel 138 and shielded from external sources of contamination, depending on the particular application. As shown in fig. 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 the IC 164 may be carried on a substrate of the RFID tag 132. When both are provided, in one embodiment, the first switch 134 and the second switch 135 may be electrically coupled with the RFID tag 132 in a series arrangement. In some embodiments, a series arrangement is used to establish a continuous loop with beneficial circuitry and detection capability. For example, when the continuous loop is open at one or both of the switches 134, 135, detection of a consequent discontinuity can be readily performed. In other embodiments, the electrical coupling between the first and second switches 134, 135 and the RFID tag 132 may have an arrangement other than a series arrangement at the IC 164, for example, to enable the ability to communicate the status of each switch 134, 135 independently of the other, as described above. Furthermore, as previously described with reference to fig. 3, in the embodiment of fig. 5-11, the fluid line connector 112 may include more than one RFID tag.

In an alternative to the embodiment of fig. 5-11, the fluid line connector 112 may be equipped with: i) Only the first switch 134 and the first actuator member 136, ii) only the second switch 135 and the second actuator member 137, or iii) both the first switch 134 and the second switch 135 and both the first actuator member 136 and the second actuator member 137. A third [ iii) ] alternative is depicted in the figure, but one skilled in the art can easily devise the first [ i) ] and second [ ii) ] alternatives by removing the other from the fluid line connector 112 in the figure.

Turning now to fig. 10, the first switch 134 and the second switch 135 are electrically coupled with the RFID tag 132 to communicate their status to the RFID tag 132 based on the impact or non-impact of the first actuator member 136 and the second actuator member 137 on the switches 134, 135. The electrical coupling may be in the form of a wire 175 that spans from the first switch 134 and the second switch 135 to the RFID tag 132. The wiring may establish a series arrangement. In the example of the wire 175, the wire 175 may pass through one or more grooves in the body 126, or may be embedded within a wall of the body, among other possibilities. In various embodiments, the first and second switches 134, 135 may take various forms, in some cases depending on the design and configuration of the RFID tag and accompanying actuator components with which they interact. In embodiments where both switches 134, 135 are present, the first switch 134 and the second switch 135 may take different forms with respect to each other. In fig. 10, the first switch 134 and the second switch 135 are in the form of buttons 166. The button 166 is in a closed state when impacted and physically pressed by a particular actuator member. And when not impacted and physically pressed by a particular actuator member, the button 166 is in an off state.

The first and second actuator members 136, 137 receive abutment during and when fully secured between the fluid line connector 112 and the connector 114 and are thereby actuated and in turn strike the first and second switches 134, 135, respectively, to close the switches. In different embodiments, the first actuator member 136 and the second actuator member 137 may have different designs, configurations, and components, depending in some cases on the design and configuration of the particular switch and connector. In embodiments where both actuator members 136, 137 are present, the first actuator member 136 and the second actuator member 137 may take different forms with respect to each other.

In the embodiment of the drawings, turning now to fig. 5, 8 and 10, the first actuator member 136 is intended to facilitate detection of axial insertion of the connector 114 in the fluid line connector 112. The first actuator member 136 is located adjacent to an inlet 163 of the channel 138. Generally, the first actuator member 136 resembles a side-turned V-shape. When assembled, the longitudinal extent 177 of the first actuator member 136 is disposed generally in line with the direction 179 in which the connector 114 is inserted into the fluid line connector 112. The longitudinal extent 177 is generally aligned with the axis of the channel 138 at the inlet 163. The first actuator member 136 has a base 181 and an accessory 183 depending from the base 181. The base 181 carries the first switch 134 and is inserted and received in the first receptacle 159 of the body 126. When the first actuator member 136 receives an abutment from the connector 114, the accessory 183 can move on an arcuate path 185 relative to the base 181. As shown in fig. 5, the appendage 183 is partially suspended within the channel 138 prior to insertion of the connector 114 such that the ramp 119 of the connector can abut the appendage 183 after insertion. When the accessory 183 is in a rest state and not in abutment with the ramp 119, the accessory 183 remains in this extended and suspended position, which constitutes the unactuated state of the first actuator member 136 and the corresponding open state of the first switch 134. When abutted, the accessory 183 then moves toward the base 181 and impacts the first switch 134, which constitutes an actuated state of the first actuator member 136 and a corresponding closed state of the first switch 134.

On one side, the attachment 183 has an outer working surface 187 that remains generally facing the channel 138 and connector 114. On its opposite side, the accessory 183 has an inner working surface 189 that remains generally facing the first switch 134. A tab 191 may extend from the inner working surface 189 for direct impact with the first switch 134. The accessory 183 has a proximal end 193 and a distal end 195, the accessory 183 being curved about the proximal end 193 relative to the base 181. Proximal end 193 acts as a hinge and distal end 195 forms the free end of accessory 183. For the first actuator member 136, the axis 197 of the hinge is located in an arrangement that is generally orthogonal to the direction 179 in which the connector 114 is inserted into the fluid line connector 112, and is also generally orthogonal to the axis of the channel 138 at the inlet 163.

In this embodiment, the second actuator member 137 has a similar design and construction as the first actuator member 136. Turning now to fig. 9, the second actuator member 137 is intended to facilitate detection of the correct positioning of the retainer 129 and the accompanying receipt of the legs 169, 171 in the slot 117. The second actuator member 137 is located at a position outside the channel 138 and on one side of the body wall; however, in other embodiments not described, the second actuator member may be located inside the body 126, but need not be located outside. Because of its location, and unlike the first actuator member 136, the longitudinal extent 177 of the second actuator member 137 is disposed generally transverse to the direction 179 in which the connector 114 is inserted into the fluid line connector 112. The longitudinal extent 177 is generally orthogonal to the axis of the channel 138 at the inlet 163. The base 181 of the second actuator member 137 carries the second switch 135 and is inserted and received in the second socket 161 of the body 126. The appendage 183 is located on the exterior of the body with its distal end 195 intersecting the path along which the terminal foot 173 descends and rests when the retainer 129 is in its first and third use positions. In this way, as the legs 169, 171 move in the slot 117, the terminal foot 173 may abut the accessory 183 and, thus, may cause actuation of the second actuator member 137. Actuation of the second actuator member 137 via abutment from the terminal foot 173 is shown in fig. 9. When the accessory 183 is stationary and when the accessory 183 is not in abutment with the terminal foot 173, the accessory 183 remains in its extended position, which constitutes the unactuated state of the second actuator member 137 and the corresponding open state of the second switch 135. When the retainer 129 is in its second use position, the accessory 183 is free of abutment from the terminal foot 173. When abutted by the terminal foot 173, the accessory 183 then moves toward the base 181 and impacts the second switch 135, which constitutes an actuated state of the second actuator member 137 and a corresponding closed state of the second switch 135. For the second actuator member 137, the axis 197 of the hinge is arranged generally in line with the direction 179 of insertion of the connector 114 into the fluid line connector 112 and likewise generally in line with the axis of the channel 138 at the inlet 163.

The embodiment of the fluid line connector 112 using two switches 134, 135 and two actuator members 136, 137 provides fully fixed enhanced resolution and prevents false negative detection readings (false-negative detection reading). Turning now to fig. 6, a first bar graph 200 shows the state of the first switch 134 when the connector 114 is inserted to a particular axial insertion depth of the fluid line connector 112, and a second bar graph 202 shows the state of the second switch 135 when the connector 114 is inserted to the same axial insertion depth of the fluid line connector 112. The first bar graph 200 and the second bar graph 202 are examples and may be different in other embodiments. In fig. 6, the first bar graph 200 and the second bar graph 202 are placed alongside the connector 114 and parallel to the axis of the connector 114 as representations of the respective axial cross-sections of the connector 114 when the connector 114 is inserted into the fluid line connector 112, and the two axially overlap. Although not necessary in all embodiments, the first bar graph 200 and the second bar graph 202 are based on the assumption that the retainer 129 is initially in its first use position. In this embodiment, the first switch 134 should be in its open state along the connector 114 to a first axial insertion depth 204 (or initial axial insertion depth) of the fluid line connector 112. Along a first axial depth 206 of the connector 114 into which the fluid line connector 112 is inserted, the second switch 135 may be in its closed state. Further, along the second axial insertion depth 208 (or intermediate axial insertion depth), the state of the first switch 134 may be indeterminate and the first switch 134 may be in its closed state. As shown, at the second axial insertion depth 208, the retainer 129 has now engaged the ramp 119 and the appendage 183 of the first actuator member 136 is abutted by the ramp 119 or extension 115. Along the second axial insertion depth 209, the state of the second switch 135 may be indeterminate or may be closed. Along the third axial insertion depth 210, the second switch 135 should be in its off state. Here, the ramp 119 again engages the retainer 129 at the 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 its closed state. And along the fourth axial insertion depth 214, the second switch 135 should also be in its closed state. At the third axial insertion depth 212 and the fourth axial insertion depth 214, the first leg 169 and the second leg 171 are received in the slot 117 and the fluid line connector 112 and the connector 114 are fully secured together. Likewise, the first and second actuator members 136, 137 are actuated and strike the first and second switches 134, 135 at the third and fourth axial depths of insertion 212, 214. During movement of the connector 114 into the fluid line connector 112, in this embodiment, the first switch 134 enters an indeterminate state from its open state and into its closed state; and the second switch 135 goes from its closed state to an indeterminate state, to its open state, and then back to its closed state. In a sense, the second switch 135 functions as a momentary switch and is in its closed state only when impacted by the second actuator member 137. Further, false negative detection readings are prevented because the second switch 135 is simultaneously in its open state at the third axial insertion depth 210 when the first switch 134 initially enters its closed state (or at least may be in its closed state) at the second axial insertion depth 208. In other words, at least one of the first switch 134 or the second switch 135 remains in its off state until the third axial insertion depth 212 and the fourth axial insertion depth 214.

However, additional alternatives are possible for the embodiments of fig. 5-11. In one alternative, the impact from the first and second actuator members 136, 137 changes the state of the respective first and second switches 134, 135. For example, the switch is brought from an initial open state to a subsequent closed state via a bump, or conversely, the switch is brought from an initial closed state to a subsequent open state via a bump. In another alternative, the first switch 134 itself may receive an abutment from the connector 114, with the first actuator member 136 being acted upon indirectly and moved indirectly through the abutment via the first switch 134.

Referring now to fig. 12 and 13, another embodiment of a fluid line connector and assembly 310 is shown. This embodiment has some similarities to the embodiments of fig. 1-4 and the embodiments of fig. 5-11, and similarities may not be repeated in the description of the embodiments of fig. 12 and 13. The fluid line connector and assembly 310 includes a fluid line connector 312 and another separate and discrete connector 314. The fluid line connector 312 has a quick connect function, can be readily connected and disconnected from the connector 314, and is used to connect automatic fluid lines together with 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 (commonly referred to as a ferrule). As shown in fig. 12 and 13, the fluid line connector 312 receives insertion of the connector 314. In the figures, the fluid line connector 312 has a curved, L-shaped configuration, but may have a straight, in-line configuration in other embodiments. In many possibilities, the connector 314 may be an integral and somewhat unitary part of a larger component such as a vehicle battery tray or heat exchanger, or may be an integral and somewhat unitary part of a fluid circuit.

Referring specifically to fig. 13, the connector 314 in this embodiment has a ramp 319 and a slot 317. Ramp 319 is located a distance from end 321 but closer to end 321 than slot 317. The chamfer 319 establishes an increased diameter on the exterior of the connector 314. As described below, the socket 317 receives insertion of a retainer of the fluid line connector 312. The slots 317 circumferentially span around the connector 314.

In different embodiments, the fluid line connector 312 may have various designs, configurations, and components. In the embodiment shown in fig. 12 and 13, 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 an actuator member 336; however, in other embodiments, the fluid line connector 312 may have more, fewer, and/or different components. Turning particularly to fig. 13, body 326 has a channel 338 defined in its structure for allowing fluid flow through fluid line connector 312. An insert assembly may be disposed within the interior of the fluid line connector 312 and within the channel 338. Depending on its design and construction, the insert assembly may facilitate mating, receiving, and/or sealing between the fluid line connector 312 and the connector 314. In embodiments herein, the insert assembly includes an O-ring 345. In addition, body 326 has structure that cooperates with retainer 329 to provide a quick connect function of fluid line connector 312. Referring to fig. 12, a first opening 349 and a second opening (not visible) are defined on opposite sides of the body wall and span completely through the body wall and open to the channel 338. On the outside of the wall, a first recess 353 and a second recess (also not visible) are used for temporary deployment of the retainer 329. The flange 357 protrudes radially outward of the body wall and partially blocks portions of the retainer 329 to prevent the retainer 329 from accidentally falling out when received in the slot 317. To accommodate the use of the actuator member 336, a penetration 344 is defined in the wall of the body and spans completely through the wall of the body and opens into the channel 338. The actuator member 336 may be accessible at the channel 338 through the penetration 344. The actuator member 336 is located in the penetration 344 and passes through the penetration 344. As shown in fig. 13, the penetration 344 is located near an end of the body 326 that receives insertion of the connector 314 so that the actuator member 336 may interact with the connector 314 as described below.

Cover 342 is carried by body 326 and partially or mostly encloses RFID tag 332 to protect RFID tag 332 from exposure to foreign objects and things during use of fluid line connector 312. The cover 342 may have various designs and configurations. In this embodiment, when in place, cover 342 is positioned at the outer boundary of body 326 and completely encloses RFID tag 332. For attachment to body 326, cover 342 has a pair of extensions 343 (only one visible in fig. 12) on each side of its structure that snap over the interconnect structure on body 326 to establish attachment thereto. Further, as also described below, in the embodiments presented herein, the actuator member 336 is an integral structure of the cover 342. The actuator member 336 extends integrally from a front end 345 of the cover 342. Here, the actuator member 336 extends at the outer circumference 347 of the cover 342. This configuration facilitates assembly and installation of actuator member 336 because actuator member 336 is carried by cover 342 and received in throughpiece 344 when cover 342 is attached to body 326. Moreover, in other embodiments, the cover 342 and the actuator member 336 need not present the unitary structure described herein.

Retainer 329 interacts with body 326 to provide a quick connect function of fluid line connector 312 such that connector 314 can be easily inserted and retained in fluid line connector 312 and can be released and removed from fluid line connector 312 as needed or desired. Retainer 329 may vary in design and construction. Referring specifically to fig. 12, in this embodiment, retainer 329 is an inwardly biased integral 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 leg 369 and the second leg can be substantially similar in shape and size. In the first use position, retainer 329 is carried by body 326 with first leg 369 and second leg moving through first opening 349 and second opening. The first leg 369 and the second leg portion are positioned within the channel 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 being inserted into fluid line connector 312 and ramp 319 is engaged with first leg 369 and the second leg. This engagement urges the first leg 369 and the second leg apart from each other (i.e., radially outward) and may move the bridge 373 radially outward. As the connector 314 continues to be inserted, the retainer 329 is brought to a third use position or fixed position in which the retainer 329 is received in the slot 317. A third use position is shown in fig. 12 and 13. The first leg 369 and the second leg ride over the ramp 319 and can snap back to their first use position but are now received in the slot 317. The first leg 369 and the second leg move through the first opening 349 and the second opening, respectively. First leg 369 and second leg are received into slot 317 to secure fluid line connector 312 and connector 314 together. Movement of the retainer 329 between its first, second and third use positions causes the retainer 329 to move in a direction generally transverse and orthogonal to the insertion direction 379 (fig. 13) of the connector 314 into the fluid line connector 312, in other words, the retainer movement is generally radially outward and radially inward, or up and down. When a serviceman pulls up on the retainer 129 to release and remove the connector 114 from the fluid line connector 112, the terminal foot 173 (fig. 9) of the first leg 169 may seat in the first recess 153, as well as the terminal foot (not specifically shown) of the second leg 171 may seat in the second recess 155.

RFID tag 332 helps to detect proper and complete securement between fluid line connector 312 and connector 314. The RFID tag 332 communicates with an RFID interrogator or reader 356 (fig. 12). The RFID interrogator 356 sends an interrogation signal 358 to the RFID tag 332, which in turn communicates with the RFID interrogator 356. In this way, a correct and complete stationary detection is achieved by using RFID technology. For example, in a manufacturing facility, RFID interrogator 356 may be located in an assembly, inspection, and/or installation line and an interrogation zone may be established in which RFID interrogator 356 attempts to communicate with RFID tag 332 as fluid line connectors and assemblies 310 and larger applications are transported through the fixed zone. Depending on the manufacturing facility, RFID interrogator 356 may establish an interrogation zone that spans several meters from RFID interrogator 356. In another arrangement, or just another example, the RFID interrogator 356 may be a mobile device, such as a handheld device.

In this embodiment, RFID tag 332 is a passive RFID tag type, but may be another type, such as an active RFID tag. Communications received from RFID tag 332 may convey various data and information to RFID interrogator 356. In one embodiment, the information communicated may be an indication of the status of the securement between the fluid line connector 312 and the connector 314. For example, when fluid line connector 312 and connector 314 exhibit complete securement, RFID tag 332 may transmit the complete securement to RFID interrogator 356 in the form of an ON signal. Conversely, when fluid line connector 312 and connector 314 are not fully secured, RFID tag 332 may transmit the information of the not fully secured to RFID interrogator 356 in the form of an OFF signal. The RFID interrogator 356 may in turn process the transmitted information. The information transmitted may also include part serial number, installation location, date of installation, etc.

RFID tag 332 is carried by body 326. The support between RFID tag 332 and body 326 may be achieved in various ways. In this embodiment, the RFID tag 332 is located at the outer boundary of the body and is protected by the cover 342 when installed. In this position, the RFID tag 332 is not exposed to the fluid flow traveling through the channel 338 and is shielded from external sources of contamination depending on the particular application. RFID tag 332 may have a similar design as 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 other designs than that of FIG. 11.

Turning now to fig. 13, the switch 334 is electrically coupled to the RFID tag 332 to communicate its status to the RFID tag 332 based on the impact or lack thereof of the actuator member 336 against the switch 334. The electrical coupling may be in the form of wiring. In this embodiment, switch 334 is mounted directly to and carried by RFID tag 332. The switch 334 is carried at the location of the RFID tag 332 such that, upon assembly, the switch 334 is physically sandwiched by the actuator member 336, as shown in fig. 13. In the orientation of fig. 13, switch 334 is located on the underside of RFID tag 332. In various embodiments, the switch 334 may take various forms, depending in some cases on the design and configuration of the RFID tag and accompanying actuator member with which it interacts. In fig. 13, switch 334 is in the form of a button 366. Button 366 is in a closed state when impacted and physically pressed by actuator member 336. And when not impacted and physically pressed by the actuator member 336, the button 366 is in an off state.

The actuator member 336 is configured to strike the switch 334 and change its state (e.g., from an open state to a closed state, and vice versa) upon actuation. In this embodiment, the actuator member 336 actuates and strikes the switch 334 only when two actions occur: a) Inserting connector 314 into fluid line connector 312, and b) moving retainer 329 to its secured position. If there is no or one of these two actions, the actuator member 336 remains unactuated and the switch is not bumped. In different embodiments, the actuator member 336 may have different designs, configurations, and components depending on the design and configuration of the particular switch and connector. In the embodiment of fig. 12 and 13, as previously described, the actuator member 336 is an integral extension of the cover 342. As shown in fig. 13, the actuator member 336 is received in the throughgoing member 344 upon assembly and installation. In this position, actuator member 336 is partially suspended within channel 338 to receive an abutment from connector 314 when connector 314 is in the middle of insertion of fluid line connector 312, and is partially exposed to the exterior of body 326 to receive an abutment from retainer 329. The actuator member 336 is located near the inlet 363 of the channel 338. The longitudinal extent 377 of the actuator member 336 is arranged substantially in line with the insertion direction 379.

In this embodiment, actuator member 336 has a base 381 and an accessory 383 depending from base 381. Typically, the base 381 is located outside of the channel 338 and faces the retainer 329, while the accessory 383 is located at the channel 338 and partially suspended therein and faces the connector 314. With respect to switch 334, base 381 is located radially outward thereof and accessory 383 is located radially inward thereof opposite thereto. In this way, the switch 334 is sandwiched by the actuator member 336, and the actuator member 336 can press the switch 334 on each side. Base 381 spans directly and immediately from cover 342, and accessory 383 spans directly and immediately from base 381.

The first extension 385 connects the cover 342 and the base 381 together, and the second extension 387 connects the base 381 and the accessory 383 together. The second extension 387 has a bend therein and wraps the actuator member 336 over and around the edge of the RFID tag 332 and positions the accessory 383 below the base 381 relative to the orientation of fig. 13. Opposite the second extension 387, the accessory 383 has a distal end and a free end 388 (fig. 13). The base 381 has a first working surface 389 directly facing the retainer 329 for abutment therewith, and the accessory 383 has a second working surface 391 facing the connector 314 for abutment therewith. The first working surface 389 is generally radially outward and the second working surface 391 is generally radially inward. The first working surface 389 receives an abutment from the retainer 329 and the second working surface 391 receives an abutment from the connector 314. An arcuate mounting socket 393 (fig. 13) is located at base 381 to receive and support bridge 373 of retainer 329 when retainer 329 is brought to its secured position. And opposite the second working surface 391, the accessory 383 has an inner working surface 392, which inner working surface 392 is generally facing the switch 334 for directly striking the switch 334.

During insertion of connector 314 into fluid line connector 312 and stationary retainer 329, actuator member 336 moves as described below. To facilitate movement of the actuator member, a first hinged end 395 is located at the first extension 385 and a second hinged end 397 is located at the second extension 387. In this embodiment, the first hinge end 395 is a thin wall portion with respect to the thickness of the immediately surrounding wall portion. The first hinged end 395 defines a first axis 399 (fig. 12). Movement of a portion of the actuator member may include deflection and displacement of the base 381 relative to the cover 342 about the first hinged end 395 and the first axis 399. Similar to the first hinged end 395, the second hinged end 397 defines a second axis 401 (fig. 12). Movement of another portion of the actuator member may include deflection and displacement of the accessory 383 relative to the base 381 about the second hinged end 397 and the second axis 401. In this embodiment, the first axis 399 and the second axis 401 are parallel to each other and are arranged substantially orthogonal with respect to the insertion direction 379.

In the embodiment of fig. 12 and 13, the actuator member 336 actuates and strikes the switch 334 only when: i) The connector 314 is fully and completely inserted into the fluid line connector 312, and ii) the retainer 329 is eventually and completely moved to its secured position. Conditions i) and ii) are as shown in fig. 12 and 13. If one of the two conditions i) or ii) is not present, or both conditions i) and ii) are not present, the actuator member 336 is not actuated and the switch 334 is not bumped. Thus, switch 334 will change state only if conditions i) and ii) are both met, and fluid line connector 312 will indicate proper and complete securement only if conditions i) and ii) are both met. As illustrated and unlike previous approaches, the fluid line connector 312 uses a single switch and a single actuator member to provide detection of two conditions (the condition of the connector 314 [ i.e., i) ] and the condition of the retainer 329 [ i.e., ii) ].

During use of the fluid line connector 312, the connector 314 is inserted into the fluid line connector 312 and the ramp 319 abuts the accessory 383. The second working surface 391 is in direct contact with the outer surface of the ramp. A first force is applied from ramp 319 to accessory 383. The first force is generally transverse to the insertion direction 379. In response, and when connector 314 reaches its full insertion depth as shown in fig. 13, both accessory 383 and base 381 move to some extent (there is no retainer 329 in its fixed position), movement of accessory 383 and base 381 does not result in impact of switch 334. The accessory 383 moves along an arcuate path relative to the base 381 and about a second axis 401. On the other hand, in response to movement of the accessory, base 381 moves slightly outwardly relative to cover 342 and about first axis 401. The base 381 moves and in a manner that is allowed by the absence of the retainer 329 in its fixed position. In fact, it is the movement of base 381 that prevents the impact of switch 334. When the retainer 329 is moved to its secured position and the legs 369 are received in the slots 317, the retainer 329 abuts the base 381. The first working surface 389 is in direct contact with the outer surface of the retainer's bridge 373. A second force is applied from retainer 329 to base 381. Like the first force, the second force is generally transverse to the insertion direction 379. The direction of the second force is substantially opposite to the direction of the first force. In this regard, the first force and the second force act as reaction forces and reaction forces to each other (reacting and counter-forces). In response, base 381 moves inwardly relative to cover 342 and about first axis 401 and to the position best shown in fig. 13. This movement, as well as the opposing application of the first and second forces, brings the actuator member 336 to its actuated state, and the actuator member 336 impacts and presses the switch 334. The impact of switch 334 is a result of being sandwiched between base 381 and accessory 383 and between the first force and the second force.

Referring now to fig. 14-16, yet another embodiment of a fluid line connector and assembly 410 is shown. This embodiment has some similarities to the previous embodiments of fig. 1-13, and the similarities may not be repeated in the description of the embodiments of fig. 14-16. The fluid line connector and assembly 410 includes a fluid line connector 412 and another separate and discrete connector. The fluid line connector 412 has a quick connect function, can be readily connected and disconnected from a separate connector, and is used to connect automatic fluid lines together with other fluid lines in other applications. For example, in an automatic fluid line application, the fluid line connector 412 may be equipped with a coolant fluid line in an electric vehicle battery installation, or may be equipped with an internal tank inside an automobile fuel tank, where the fluid line connector 412 will be inaccessible after installation, among other possibilities. In the case of an internal tank application, since the fluid line connector 412 is located internally, subsequent repair of the fluid line connector 412 can be challenging and often costly. In the embodiment of fig. 14-16, the fluid line connector 412 is a female connector and the discrete connector is a male connector (commonly referred to as a ferrule). The fluid line connector 412 receives the insertion of a separate connector. In the figures, the fluid line connector 412 has a curved L-shaped configuration, but may have a straight, in-line configuration in other embodiments. In many possibilities, the discrete connector may be an integral and somewhat unitary part of a larger component such as a vehicle battery tray or heat exchanger, or may be an integral and somewhat unitary part of a fluid circuit.

The discrete connector in this embodiment may be similar to the connector 14 described with reference to fig. 2 and 4. Thus, a discrete connector may have a first flange projecting radially outwardly from its body and a second flange projecting radially outwardly from its body. The first flange and the second flange may be axially spaced apart from each other and may span circumferentially around the discrete connector.

In different embodiments, the fluid line connector 412 may have various designs, configurations, and components. In the embodiment shown in fig. 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. Moreover, in other embodiments, the fluid line connector 412 may have more, fewer, and/or different components; for example, the fluid line connector 412 need not have the O-ring 428 and insert 430 presented herein, may have inserts of different designs and configurations, may have another insert assembly that facilitates mating and/or receiving and/or sealing in another manner, or need not have one or both of these components at all. Turning specifically to fig. 14, the body 426 has a passage 438 defined in its structure for allowing fluid flow through the fluid line connector 412. The channel 438 constitutes the primary channel of the fluid line connector 412. Body 426 also has a compartment 440 for receiving and placing RFID tag 432. Compartment 440 is a space separate from channel 438. A removable cover 442 may be provided to close compartment 440 and enclose RFID tag 432 therein. In other embodiments, the reception and placement of RFID tag 432 may have different designs and configurations, including embodiments according to those described elsewhere in this patent application.

The body 426 also has a throughgoing member 444 for positioning and placing the actuator member 436 within the body 426 when assembled. When the actuator member 436 is not assembled in the penetration 444, the channel 438 and the compartment 440 communicate with each other through the penetration 444, and the penetration 444 is open to both the channel 438 and the compartment 440. The penetration 444 spans axially between the channel 438 and the compartment 440, as shown in phantom in fig. 14. An O-ring 428 is received within the channel 438 and forms a seal between the fluid line connector 412 and a separate connector. Insert 430 is also received within channel 438 and serves to help retain the discrete connector when the discrete connector and fluid line connector 412 are secured together. In the example of fig. 14, the insert 430 has a pair of tangs 446 with hooked ends 448 that capture the first flange when the discrete connector is inserted into the fluid line connector 412 to a sufficient depth of overlap. The insert 430 includes a first annular structure 450 and a second annular structure 452 bridged together by a tang 446. The press down 454 on opposite sides of the second annular structure 452 may be pressed to release and release the captured first flange to detach the discrete connector from the fluid line connector 412.

RFID tag 432 facilitates detection of proper and complete securement between fluid line connector 412 and a separate connector. RFID tag 432 communicates with an RFID interrogator or reader 456 (fig. 14). The RFID interrogator 456 transmits an interrogation signal 458 to the RFID tag 432, which in turn may communicate with the RFID interrogator 456. In this way, a correct and complete stationary detection is achieved by using RFID technology. For example, in a manufacturing facility, RFID interrogator 456 may be located in an assembly, inspection, and/or installation line and an interrogation zone may be established in which RFID interrogator 456 attempts to communicate with RFID tag 432 as fluid line connectors and assemblies 410 and larger applications are transported through the fixed zone. Depending on the manufacturing facility, RFID interrogator 456 may establish an interrogation zone that spans several meters from RFID interrogator 456. In another arrangement, or just another example, the RFID interrogator 456 may be a mobile device, such as a handheld device.

In this embodiment, RFID tag 432 is a passive RFID tag type, but may be another type, such as an active RFID tag. Communications received from RFID tag 432 may convey various data and information to RFID interrogator 456. In one embodiment, the information may be an indication of the status of the securement between the fluid line connector 412 and the discrete connector. For example, when fluid line connector 412 and a separate connector appear to be fully stationary, RFID tag 432 may transmit the fully stationary information to RFID interrogator 456 in the form of an ON signal. Conversely, when the fluid line connector 412 and the separate connector are not fully secured, the information of the incomplete securing may be determined in the absence of a signal from the RFID tag 432 to the RFID interrogator 456 or the RFID tag 432 may be silent, or the RFID tag 432 may transmit the information of the incomplete securing to the RFID interrogator 456 in the form of an OFF signal. These are merely examples of ways to indicate a fixed state between the fluid line connector 412 and a separate connector; in other embodiments, other examples are possible. The RFID interrogator 456 may in turn process the information. The information may also include part serial number, installation location, date of installation, etc.

In this embodiment, RFID tag 432 is carried by body 426, or at least is located near body 426. The support between the RFID tag 432 and the body 426 may be achieved in various ways. In this embodiment, RFID tag 432 is located within compartment 440 and is protected by cover 442 when installed. In this position, RFID tag 432 is shielded from exposure to fluid flow through channel 438 and shielded from external sources of contamination, depending on the particular application. Referring now to fig. 15, rfid tag 432 has a circuit 464 in the form of a substrate 423 and an integrated circuit, the circuit 464 storing data and information and possibly other functions. The circuit 464 is disposed on the substrate 423. The circuit 464 includes a circuit path 425, the circuit path 425 being established by conductive traces 427 disposed on the substrate 423. In one example, the conductive trace 427 may be composed of copper. Current may flow through circuit path 425 via conductive trace 427. A circuit breaker 431 in circuit 464 interrupts the continued flow of current in circuit path 425. The circuit breaker 431 can be designed and constructed in different ways. In the embodiment of fig. 15, the open circuit 431 is established by a break 433 in the circuit path 425. The discontinuity 433 interrupts the continuity of the current in the circuit path 425. Here, the circuit path 425 terminates at a first circuit path end 435 at one location and terminates at a second circuit path end 437 at another location. The first circuit-path end 435 and the second circuit-path end 437 are positioned adjacent to each other and face each other across the gap defined by the discontinuity 433. A break 433 is established via a first circuit path end 435 and a second circuit path end 437. According to one example, the first circuit path end 435 and the second circuit path end 437 may be comprised of a conductive ink, such as a conductive carbon ink, in another example comprised of copper pads, or comprised of other objects. Nonetheless, RFID tag 432 may have more, fewer, and/or different circuit components than presented herein; its exact components may be determined by the intended function of the RFID tag 432.

The actuator member 436 receives abutment during and when fully secured between the fluid line connector 412 and the discrete connector. In different embodiments, actuator member 436 may have various designs, configurations, and components depending on the design and configuration of body 426, RFID tag 432, and/or the discrete connector. In this embodiment, referring now to fig. 14 and 16, an actuator member 436 extends between the channel 438 and the RFID tag 432 and provides a relationship between the discrete connector and the RFID tag 432. When assembled, the actuator member 436 is carried within the body 426 of the fluid line connector 412 and positioned and seated in the throughgoing member 444. In its assembled position, the actuator member 436 has one end at the channel 438 and the other end at the RFID tag 432. In this embodiment, the actuator member 436 is in the form of a cam member 472. Cam member 472 is unitary and has a generally U-shaped profile. The cam member 472 has a base portion 474 and a pair of prong portions 476 depending from the base portion 474. When the cam member 472 is positioned in the penetration 444, the base portion 474 directly faces and opposes the RFID tag 432 across the space established therebetween, particularly at the first circuit path end 435 and the second circuit path end 437, to the circuit path 425. In the depiction of fig. 16, base portion 474 is shown as having a slightly arcuate shape. In other embodiments, however, the base portion 474 may have other designs, configurations, and shapes to facilitate bridging the circuit breaker 431 during use of the fluid line connector 412. For example, the shape of the base portion 474 may be flatter and less curved than shown in FIG. 16. Indeed, in some embodiments, protrusions or protuberances on each side of the base portion 474 may extend upward from the base portion 474 in a direction opposite the tine portion 476; here, the protrusion/projection may more easily contact the circuit 464 for bridging purposes.

The tine portion 476 includes a first tine portion 475 and a second tine portion 477. The first and second tine portions 475, 477 each have a working surface 480, the working surface 480 being defined near the ends of the first and second tine portions 475, 477. When assembled, the working surface 480 is suspended and partially or more partially located at the channel 438, where the working surface 480 may be abutted by a separate connector when the separate connector is inserted into the fluid line connector 12. To facilitate abutment with a discrete connector, the working surface 480 may be angled upwardly toward the base portion 474 and relative to the main longitudinal axis of the discrete connector.

To bridge the break 431 and achieve continuity at the discontinuity 433, the actuator member 436 has a working portion 481 composed of an electrically conductive material. When the working portion 481 bridges the open circuit 431, as described in more detail below, current can flow and travel between the first circuit path end 435 and the second circuit path end 437 of the circuit path 425 via the working portion 481 and its conductive components. Once bridged, current may travel from the first circuit-path end 435 to the second circuit-path end 437, and vice versa, through the working portion 481. Depending on the embodiment, the conductive material may be copper, graphite, silver or carbon particles, or other conductive materials. When the actuator member 436 is positioned in the penetration 44 in the unactuated state and position, the working portion 481 faces the circuitry 464 of the RFID tag 432 across the gap established therebetween.

In different embodiments, the working portion 481 may take different forms. In one embodiment, the working portion 481 is comprised of a working surface 483 of the actuator member 436. The working surface 483 is the exterior and outboard surface of the base portion 474. The working surface 483 directly and immediately faces and opposes the circuit path 425 at the first circuit path end 435 and the second circuit path end 437. For current flow through the working surface 483, the conductive ink 485 is applied and located on a portion or portions of the working surface 483 (conductive ink 485 is represented in fig. 16 by the depiction surrounded by the dashed line; the depiction and dashed line are not necessarily intended to present an exact arrangement of conductive ink 485 applied on the working surface 483, but are shown for illustrative purposes). Conductive ink 485 may be a conductive carbon ink, a conductive graphite ink, or the like. In this embodiment, other portions of the actuator member 436 may be composed of a material different from the material of the conductive ink 485 at the working surface 483; for example, the base portion 474 and the tine portion 476 may be constructed of a plastic material or a non-conductive material. In this way, current flow may occur only via conductive ink 485 without current flow in other areas of base portion 474 and tine portions 476. In another embodiment, the working portion 481 is formed from a portion or more of the base portion 474. For example, the entire base portion 474 may be the working portion 481, and thus the entire base portion 474 will be composed of an electrically conductive material (this possibility is indicated by reference numeral 487 in FIG. 16; as previously noted, the depiction and dashed lines are for illustrative purposes). In another example of this embodiment, one layer of the base portion 474 may be the working portion 481, and thus the layer will be composed of an electrically conductive material. The layer will have a greater thickness and depth than just one surface. In this embodiment and these examples, other portions of the actuator member 436 may be composed of a material different from the material of the conductive material; for example, other portions similar to the tine portions 476 may be constructed of a plastic material or a non-conductive material. Then, current flow may occur only via the conductive material, however configured, and current flow may not occur in other areas (e.g., in the tine portion 476). However, in yet another embodiment, the working portion 481 is comprised of the entire actuator member 436, and thus the entire actuator member 436 is comprised of the electrically conductive material.

Furthermore, unlike the first embodiment of the fluid line connector of fig. 1-4, the embodiment of the fluid line connector 412 of fig. 14-16 has no switching component at the RFID tag 432. No switching component is interposed between the actuator member 436 and the RFID tag 432. Instead, the actuator member 436 and its working portion 481 have a direct and immediate path of engagement and interaction with the RFID tag 432, and no switching components, nor any other components, therebetween.

When the fluid line connector and assembly 410 is employed in use, proper and complete securement may be detected by RFID technology. When the discrete connectors are inserted into the body 426 and the channel 438, the fluid line connector 412 and the discrete connectors are brought together. The first flange of the discrete connector abuts the actuator member 436 (i.e., the cam member 472 in this embodiment) when inserted. Cam member 472 is in an unactuated state and position prior to abutment. In its unactuated state and position, cam member 472 is spaced from RFID tag 432 and is not in contact with RFID tag 432 nor with circuit 464. The break 431 is not bridged and no continuity is achieved at the break 433. According to one embodiment, there is no such contact and when cam member 472 is in the unactuated state and position, RFID tag 432 and RFID interrogator 456 are prevented from communicating with each other. The absence of communication and the resulting silence of RFID tag 432 serve as an indication that fluid line connector 412 and the separate connector are not fully secured. In another embodiment, when cam member 472 is in the unactuated state and position and there is no contact between cam member 472 and RFID tag 432, RFID tag 432 transmits an OFF signal to RFID interrogator 456. The OFF signal is used as an indication that the fluid line connector 412 and the discrete connector are not fully secured.

The first flange of the discrete connector is in face-to-face abutment with the working surface 480 of the cam member 472 upon insertion. Cam member 472 is displaced and urged to move upwardly in a first direction that is generally transverse and orthogonal to a second direction of channel 438. Fluid flows in a second direction through the passage 438 adjacent the cam member 472; further, a separate connector is inserted into the fluid line connector 412 in a second direction. Cam member 472 is in face-to-face contact with RFID tag 432 and circuit 464. Here, the cam member 472 is in an actuated state and position. The working portion 481 is in direct contact with the circuit path 425 without any intermediate components therebetween. In particular, the working 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 outer side surfaces of the base portion 474 contact the exterior surfaces of the first circuit path end 435 and the second circuit path end 437. The circuit breaker 431 is thereby bridged via the working part 481 and the contact made and continuity is achieved at the discontinuity 433. Current can now flow from the first circuit-path end 435 through the working portion 481 to the second circuit-path end 437 and vice versa. According to one embodiment, when cam member 472 is in an actuated state and position and contacts are made, RFID tag 432 and RFID interrogator 456 are able to communicate with each other. The ability to communicate may be an indication that the fluid line connector 412 and the separate connector are fully secured. In one example, RFID tag 432 transmits an ON signal to RFID interrogator 456. The ON signal may have an indication of complete securement as the fluid line connector 412 and the discrete connector. According to one embodiment, movement of actuator member 436 from its unactuated position to its actuated position causes a change in the state of RFID tag 432. The change in state of RFID tag 432 (from the first state to the second state) serves as an indication that fluid line connector 412 and the discrete connector have reached a fully secured state.
