Technical Field

[0003] The present disclosure relates generally to connector assemblies for joining fluid lines together and, more particularly, to a manner of detecting proper and complete engagement of connector assembly components. Background Art

[0004] Connector assemblies, particularly connector assemblies with quick connect capabilities, are commonly used in vehicle applications to join fluid lines together. One example is the coolant fluid lines in an electric vehicle. For initial assembly and inspection, as well as subsequent maintenance, visual measures are sometimes used in the design and construction of connector assemblies to verify that proper and complete engagement has been formed between the components of the connector assembly. Examples include a secondary latch that can be closed when fully engaged and a window embedded in one of the components of the connector assembly for observing the engagement. These measures and others like them require physical interaction and observation by the assembler, inspector, or maintenance personnel to ensure that proper and complete engagement has been formed between the components of the connector assembly. Summary of the invention

[0005] In an embodiment, a fluid line connector may include a body, a radio frequency identification (RFID) tag, a retainer, an actuator member, and a switch. A channel exists in the body, and an opening exists in the body. The RFID tag is carried by the body. The retainer can move through the opening of the body. The actuator member is located near the channel of the body and near the retainer. The switch is electrically coupled to the RFID tag. When the switch is struck by the actuator member, the switch changes state. The strike from the actuator member occurs in the following two situations: i) another connector is inserted into the fluid line connector, and ii) the retainer moves in a direction generally transverse to the direction in which the other connector is inserted into the fluid line connector.

[0006] In another embodiment, a fluid line connector may include a body, a radio frequency identification (RFID) tag, a retainer, an actuator member, and a switch. A passage is present in the body, and an opening is present in the body. The RFID tag is carried by the body. The retainer can move through the opening of the body. The actuator member has a base and an additional portion cantilevered from the base. The switch is electrically coupled to the RFID tag. When the switch is struck by the actuator member, the switch changes state. The strike from the actuator member occurs in the following two situations: i) a first force is applied to the additional portion from another connector inserted into the fluid line connector, and ii) a second force is applied to the base from the retainer.

[0007] In yet another embodiment, a fluid line connector may include a body, a radio frequency identification (RFID) tag, a retainer, an actuator member, and a switch. A passage is present in the body, and an opening is present in the body. The retainer can move through the opening of the body. The actuator member has a base and an attachment.

[0022] Several embodiments of fluid line connectors and assemblies are described in detail in this specification. The connectors and assemblies are designed and constructed to detect proper and complete fastening between connectors without the need for the secondary latches and windows of the past, which require a certain degree of physical interaction and observation by assemblers, inspectors, or maintenance personnel at the fastening position. Instead, the connectors and assemblies of the present specification are provided with such means, wherein proper and complete fastening can be detected via a device located away from the exact fastening position of the connector, and the device does not have to make physical contact with the fastening position for detection. In this way, the connectors and assemblies are equipped for automated, mechanical and / or autonomous initial assembly, subsequent quality inspection, and subsequent maintenance techniques (e.g., those found in advanced manufacturing facilities in automotive production). Therefore, the connectors and assemblies can prove to be useful in many applications (e.g., when immediate power is not easily available and not easily nearby). This specification describes the connectors and assemblies in the context of automotive fluid lines, such as coolant fluid lines in electric vehicles, but the connectors and assemblies have broader application and are suitable for use in aircraft fluid lines, marine fluid lines, agricultural fluid lines, and other fluid lines.

[0023] As used herein, the phrase "fully secured" and its grammatical variations are used to refer to a secure state of establishing a fluid-tight joint via a fluid line connector. Additionally, unless otherwise specified, the terms radially, axially, and circumferentially, and their grammatical variations refer to directions relative to the general circle of a passageway of a fluid line connector.

[0024] In some cases, the fluid line connectors and assemblies may have various designs, configurations, and components in different embodiments, depending on the application in which they are employed. Figures 1 to 4 A first embodiment of a fluid line connector and assembly 10 is introduced. Here, 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 for easy connection and disconnection action with the connector 14, and is used to join automotive 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 spigot). In installation, the fluid line connector 12 receives insertion of the connector 14 at a first end 16 and is connected to the fluid line at a second end 18. The fluid line connector 12 has an elbow and L-shaped configuration in the accompanying drawings, but can have a straight and in-line configuration in other embodiments. Among many possibilities, the connector 14 can be an integral and somewhat monolithic part of a larger component (such as a vehicle battery tray or a heat exchanger), or can be an integral and somewhat monolithic part of a fluid line. With particular reference to Figure 2 and Figure 4 The connector 14 has a first flange 20 protruding radially outside its body, and has a second flange 22 axially spaced from the first flange 20 and also protruding radially outside the body of the connector. The first flange 20 and the second flange 22 extend circumferentially around the connector 14. The connector 14 has an outer surface 24.

[0025] 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 Figure 3 and Figure 4The 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 passage 38. A removable cover 42 can be provided to close the compartment 40 and enclose the RFID chip 32 therein. The body 26 also has a pass-through 44 for positioning and installing the actuator member 36 within the body 26 during assembly. When the actuator member 36 is removed from the body 26 (e.g., as shown in FIG. 1 ), the RFID chip 32 is placed in the body 26. Figure 3 ), the channel 38 and the compartment 40 communicate with each other via a passage 44, which is open to both the channel 38 and the compartment 40. The O-ring 28 is received in the channel 38 (possibly as Figure 4 ), and forms a seal therebetween between the fluid line connector 12 and the connector 14. The insert 30 is also received within the passage 38 and is used to help retain the connector 14 when the connector 14 and the fluid line connector 12 are fastened together. In the example of the drawings, the insert 30 has a pair of tangs 46 with hooked ends 48 that capture the first flange 20 when the connector 14 is inserted into the fluid line connector 12 to the appropriate overlap depth, as shown in FIG. Figure 4 The insert 30 includes a first ring structure 50 and a second ring structure 52 that are bridged together by the tang 46. The push-downs 54 on the opposite sides of the second ring structure 52 can be squeezed to release the captured first flange 20 so that the connector 14 can be removed from the fluid line connector 12.

[0026] The RFID chip 32 assists in detecting the proper and complete fastening between the fluid line connector 12 and the connector 14. The RFID chip 32 transmits and receives radio frequency (RF) signals through the RFID interrogator 56. The RFID interrogator 56 sends an interrogation signal 58 to the RFID chip 32, which responds to the RF signal 60. In this way, proper and complete fastening detection is performed by using RFID technology. In a manufacturing facility, for example, the RFID interrogator 56 can be placed in an assembly, inspection, and / or installation production line, and an interrogation area can be established, and when the fluid line connector and assembly 10 and larger applications are transported through the fastening area, the RFID interrogator 56 seeks to communicate with the RFID chip 32 in the interrogation area. Depending on the manufacturing facility, the RFID interrogator 56 can establish an interrogation area that spans several meters from the RFID interrogator 56. In another setting, the RFID interrogator 56 can 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 an embodiment, the transmitted information may be an indication of the tightening state between the fluid line connector 12 and the connector 14. For example, when the fluid line connector 12 and the connector 14 show complete tightening, the RF signal 60 may transmit the complete tightening information in the form of an ON signal to the RFID interrogator 56. Then, the RFID interrogator 56 may process the transmitted information. The transmitted information may also include a serial number, an installed location, etc.

[0027] With particular reference Figure 3 and Figure 4 , the RFID chip 32 is carried by the body 26. The support between the RFID chip 32 and the body 26 can be achieved in various ways. In this embodiment, the RFID chip 32 is present in the compartment 40 and is protected by the cover 42 in the installation. In this position, depending on the specific application, the RFID chip 32 is protected from exposure to the fluid flow traveling through the channel 38, as well as from external sources of contamination. The RFID chip 32 has an antenna 62 that exchanges (i.e., transmits and receives) RF signals, and has an integrated circuit (IC) 64, which stores data and information among other possible functions.

[0028] The switch 34 interacts with the RFID chip 32 so as to activate the RFID chip 32 and enable the RFID chip to transmit and receive RF signals through the RFID interrogator 56, and so as to deactivate the RFID chip 32 and disable the RFID chip 32 from transmitting and receiving RF signals. However, the interaction may affect the operation of the RFID chip 32 in other ways. In the embodiment presented by the accompanying drawings, the switch 34 is electrically coupled to the RFID chip 32 so as to enable or disable the antenna 62 to transmit and receive RF signals. In some cases, depending on the RFID chip that interacts with the switch and on the design and construction of the attached connector, in different embodiments, the switch 34 may have various designs, constructions, and components. For example, the switch 34 may take mechanical, electrical, and magnetic forms. In one embodiment and with reference to Figure 3 and Figure 4 , the switch 34 is in the form of a button 66 mounted to the RFID chip 32. Figure 4 As best shown, the button 66 is located between the RFID chip 32 and the actuator member 36 and adjacent to the passage 44. When struck and physically pressed, the button 66 (due to its electrical coupling with the RFID chip 32) activates the antenna 62 and enables the antenna to transmit and receive RF signals. Depending on the embodiment, a single press and release of the button 66 can activate the RFID chip 32, or a sustained strike and press can activate the RFID chip 32 for the duration of the strike and press. Conversely, a single press and release of the button 66 can deactivate the RFID chip 32, or a lack of a sustained strike and press can deactivate the RFID chip 32 for the duration of the absence of the strike and press.

[0029] Furthermore, in other embodiments, the switch 34 may be actuated by other means to activate and deactivate the RFID chip 32. Figure 4 , another embodiment performs the actuation by using a non-contact switch instead of a contact-based switch. The reed switch 68 is carried by the body 26 of the fluid line connector 12, and the magnetic component 70 is carried by the connector 14. Here, when the fluid line connector 12 and the connector 14 are fully tightened, the proximity between the reed switch 68 and the magnetic component 70 actuates the actuation of the RFID chip 32. Conversely, incomplete tightening and the resulting separation of the reed switch 68 and the magnetic component 70 relative to each other deactivates the RFID chip 32. In this embodiment, the actuator member 36 does not need to be provided.

[0030] The actuator member 36 receives abutment during the full tightening action and when fully tightened between the fluid line connector 12 and the connector 14, thereby actuating the impact of the switch 34. In some cases, depending on the design and construction of the switch 34 and the attached connector, in different embodiments, the actuator member 36 can have various designs, constructions, and components. In the embodiments of the drawings and now referring to Figure 3 and Figure 4 , the actuator member 36 spans between the passage 38 and the switch 34 to provide a mutual relationship 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 located and disposed in the passage 44. In its position, one end of the actuator member 36 is located at the passage 38 and the other end is located at the switch 34. Figure 3 and Figure 4 In the embodiment of the present invention, 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 having a base 74 and a pair of tines 76 depending from the base 74. The base 74 has a first working surface 78 present at and maintained in contact with the switch 34. And the tines 76 each have a second working surface 80 present in the channel 38 for abutting the connector 14 when the connector 14 is inserted into the fluid line connector 12. The second working surface 80 can be inclined relative to the axis of the connector 14 to facilitate easy abutment with the connector 14 and cause concomitant displacement of the cam member 72.

[0031] When the fluid line connector and assembly 10 are employed in use, proper and complete tightening can 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 joined together. The first flange 20 begins to abut against 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 abuts against the second working surface 80 of the cam member 72 surface to surface. The cam member 72 is pushed upward and strikes the button 66 via surface to surface contact between the first working surface 78 and the facing surface of the button 66. In this embodiment, when fully tightened, the first flange 20 remains in abutment with the cam member 72, and therefore, the cam member 72 maintains impact with the button 66.

[0032] In another embodiment, the fluid line connector 12 includes more than one RFID chip. Figure 3, in addition to the first RFID chip 32, a second RFID chip 33 is provided. And similar to the first RFID chip 32, the second RFID chip 33 assists in detecting proper and complete tightening 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 through the RFID interrogator 56. In the example, when the fluid line connector 12 and the connector 14 show complete tightening, the first RFID chip 32 can transmit complete tightening information to the RFID interrogator 56. Conversely, when the fluid line connector 12 and the connector 14 are not completely tightened together, the second RFID chip 33 can transmit the incomplete tightening information to the RFID interrogator 56. In addition, when fully tightened, the second RFID chip 33 will not transmit incomplete tightening information to the RFID interrogator 56; and when not completely tightened together, the first RFID chip 32 will not transmit complete tightening information to the RFID interrogator 56. As in the previous embodiment, the first RFID chip 32 and the second RFID chip 33 can transmit additional information (such as serial number, installed location, etc.). Whether the first RFID chip 32 transmits its complete fastening information or the second RFID chip 33 transmits its incomplete fastening information is managed in part 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 transmission and interaction of information can be achieved in different ways. For example, when being hit, the switch 34 can actuate the first RFID chip 32 and enable the first RFID chip to transmit complete fastening information, and when not being hit, the switch 34 can actuate the second RFID chip 33 and enable the second RFID chip to transmit incomplete fastening information. The impact and non-impact of the switch 34 can deactivate and disable the first RFID chip 32 or the second RFID chip 33.

[0033] Now refer to Figures 5 to 11 , presents yet another embodiment of a fluid line connector and assembly 110. This embodiment is similar to Figures 1 to 4 The embodiments have some similarities and Figures 5 to 11 These similarities may not be repeated in the description of the embodiments of the present invention. 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 for easy connection and disconnection action with the connector 114 and is used to join automotive fluid lines and other fluid lines in other applications together. 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 socket). As shown in FIG. Figure 7 As best shown, the fluid line connector 112 receives the insertion of the connector 114. The fluid line connector 112 has an elbow and L-shaped configuration in the figures, but may have a straight and coaxial 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 line.

[0034] With particular reference Figure 6 , the connector 114 has an extension 115 and a slot 117 at the end of the connector 114 inserted into the fluid line connector 112. The extension 115 can be received in a complementary cavity of the fluid line connector 112 for relative rotational alignment purposes between the connector 112 and the connector 114, and in some embodiments, the extension 115 does not need to be provided. In some embodiments, the extension 115 can abut against a first actuator member (described below) of the fluid line connector 112, and thus can drive actuation of the first actuator member. When provided, the extension 115 axially spans (spans, extends) on the inserted end of the connector 114 and protrudes radially outward of the surrounding body of the connector. As described below, the slot 117 receives the insertion of the retainer of the fluid line connector 112. The slot 117 spans (spans, extends) circumferentially around the connector 114. In addition, the connector 114 has a ramp 119. The ramp 119 presents an increased diameter in the connector 114. The outer surface 113 is positioned from the groove 117 and the ramp 119. The connector 114 is inserted into the fluid line connector 112, wherein the ramp 119 is received in the fluid line connector 112 before the extension 115 is received in the fluid line connector 112 and before the groove 117 is received in the fluid line connector (i.e., before the extension 115 is received in the fluid line connector). Figure 6 from right to left in the orientation of the ).

[0035] In by Figures 5 to 11 In the illustrated embodiment, 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. Figure 5 and Figures 7 to 9 The body 126 has a passage 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 the cover are only in contact with each other). Figure 5 and Figure 7 Depicted in Figure 8 and Fig. 9 The depiction may have a similar configuration for accommodating an RFID tag 132). The cover 142 may be removable, although not required. Figure 5 1, but an insert assembly 143 may be disposed and carried at the interior of the fluid line connector 112 and within the passage 138. Depending on its design and construction, the insert assembly 143 may facilitate mating, receiving, and / or sealing between the fluid line connector 112 and the connector 114. Depending on the embodiment, the insert assembly 143 may include, for example, an O-ring 145 and a carrier 147, and may also include a sleeve.

[0036] The body 126 has a configuration that cooperates with the retainer 129 to furnish the quick connect function of the fluid line connector 112. Referring again to Figure 5 and Figures 7 to 9 , first opening 149 and second opening 151 are defined on opposite sides of the body wall and completely span (spans, extends) through the body wall and lead to the passage 138. At the exterior of the wall, there are first recesses 153 and second recesses 155 for temporarily deploying the retainer 129 when the retainer 129 is pulled radially outward to release the connector 114 from the fluid line connector 112. A flange 157 protrudes radially outward of the body wall and partially encloses portions of the retainer 129 to prevent accidental removal of the retainer 129 when the retainer 129 is received in the groove 117.

[0037] In addition, the body 126 has a structure intended to accommodate the assembly and installation of the actuator members 136, 137. The exact design and construction of this structure may vary and may depend on the design and construction of the (multiple) actuator members and (multiple) switches utilized in the fluid line connector 112. In the embodiment presented by the drawings and now turning to Figure 5 , Figure 8 and Fig. 9, a first socket 159 and a second socket 161 are present in the body 126. The first socket 159 receives and retains the first actuator member 136, and is in the form of a slotted configuration in this embodiment. The first socket 159 is located at the entrance 163 of the passage 138 for the first actuator member 136 to be located thereat, and is defined in the body wall near the entrance 163. In order to fully receive the first actuator member 136, the axial depth of the first socket 159 can be substantially equal to the length of the first actuator member 136. And, in a similar manner, the radial width of the first socket 159 can be substantially equal to the width of the first actuator member 136. The axial depth of the first socket 159 is generally aligned with the axis of the passage 138 at the entrance 163. The accompanying drawings depict an enlarged structure in the body wall for accommodating the first actuator member 136 and for providing the first socket 159, but in other embodiments, the accommodating portion can be more continuous and integrated into the body 126 so that the enlargement can be minimized.

[0038] Now, with particular reference to Fig. 9 , the second socket 161 receives and retains the second actuator member 137 and is in the form of a slotted structure in this embodiment. The second socket 161 is located outside the channel 138 and at one side of the body wall for positioning the second actuator member 137 thereat. In order to fully receive the second actuator member 137, the radial depth of the second socket 161 may be substantially 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 substantially 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 channel 138 at the inlet 163. The accompanying drawings depict an enlarged structure protruding from the side of the body wall for accommodating the second actuator member 137 and for providing the second socket 161, but in other embodiments, the accommodating portion may be more continuous and integrated into the body 126 so that the enlarged structure may be minimized. Fig. 9 1 , the bottom wall 165 and a pair of side walls 167 depending from the bottom wall 165 together partially enclose the second actuator member 137 and help protect it from accidental contact from foreign components when the fluid line connector 112 is put into use.

[0039] The retainer 129 interacts with the body 126 to provide a quick connect feature of the fluid line connector 112 so that the connector 114 can be easily inserted and retained in the fluid line connector 112 and can be released and removed as needed or desired. The retainer 129 can vary in design and construction. With particular reference to Figure 5 and Figure 8In this embodiment, the retainer 129 is an integral stainless steel wire spring that is biased inwardly. 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 can be substantially similar in shape and size. Figure 5 , Figure 8 and Fig. 9 14 and 151. In the first use position, the retainer 129 is carried by the body 126, and the first leg 169 and the second leg 171 are moved through the first opening 149 and the second opening 151. The first leg 169 and the second leg 171 are partially present in the passage 138. In the first use position, the connector 114 is not inserted into the fluid line connector 112. The second use position of the retainer 129 is not specifically depicted in the drawings. In the second use position, the connector 114 is inserted into the fluid line connector 112, and the ramp 119 engages the first leg 169 and the second leg 171. The engagement pushes the first leg 169 and the second leg 171 away from each other (i.e., radially outward), and can 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 on the ramp 119 and can snap back into position in its first use position, but now received in the slot 117. The first leg 169 and the second leg 171 move through the first and second openings 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 use position, the second use position, and the third use position causes the retainer 129 to move generally transversely and orthogonally to the insertion direction 179 (in which the connector 114 is inserted into the fluid line connector 112) and the second leg 171 moves through the first and second openings 149, respectively. The first leg 169 and the second leg 171 move ... Figure 5 ), in other words, the movement of the retainer is radially outward and radially inward, or upward and downward. When the maintenance personnel pulls the retainer 129 upward to release and remove the connector 114 from the fluid pipeline connector 112, the end foot 173 ( Fig. 9 ) can be seated in the first recess 153, and similarly, the end foot (not specifically depicted) of the second leg 171 can be seated in the second recess 155.

[0040] Now go to Fig.11RFID tag 132 assists in detecting proper and complete tightening between fluid line connector 112 and connector 114. RFID tag 132 and RFID interrogator or reader 156 ( Figure 7 ) communication. 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, proper and complete fastening detection is performed by using RFID technology. In a manufacturing facility, for example, the RFID interrogator 156 can be placed in an assembly, inspection, and / or installation production line, and an interrogation zone can be established in which the RFID interrogator 156 seeks to communicate with the RFID tag 132 as the fluid line connectors and components 110 and larger applications are transported through the fastening area. Depending on the manufacturing facility, the RFID interrogator 156 can establish an interrogation zone that spans several meters from the RFID interrogator 156. In another setting, the RFID interrogator 156 can be a mobile device (such as a handheld device).

[0041] In this embodiment, the RFID tag 132 is a passive RFID tag type, but may be another type, such as an active RFID tag. The communication received from the RFID tag 132 may transmit various data and information to the RFID interrogator 156. In an embodiment, the transmitted information may be an indication of the tightening state between the fluid line connector 112 and the connector 114. For example, when the fluid line connector 112 and the connector 114 show complete tightening, the RFID tag 132 may transmit the complete tightening information to the RFID interrogator 156 in the form of an ON signal. And conversely, when the fluid line connector 112 and the connector 114 are not completely tightened, the RFID tag 132 may transmit the incomplete tightening information to the RFID interrogator 156 in the form of an OFF signal. Then, the RFID interrogator 156 may process the transmitted information. The transmitted information may also include a part serial number, an installed location, and the like. In embodiments where the fluid line connector 112 is equipped with both switches 134, 135 and actuator members 136, 137, the RFID tag 132 may communicate the state of each actuator member 134, 135 based on striking or not striking the switch. For example, the RFID tag 132 may transmit one or more of the following: i) both actuator components 136, 137 are not actuated and therefore both the first switch 134 and the second switch 135 are in the open state, ii) the first actuator component 136 is not actuated and therefore the first switch 134 is in the open state, while the second actuator component 137 is actuated and therefore the second switch 135 is in the closed state, iii) the first actuator component 136 is actuated and therefore the first switch 134 is in the closed state, while the second actuator component 135 is not actuated and therefore the second switch 135 is in the open state, and / or iv) both the first actuator component 136 and the second actuator component 137 are actuated and therefore both the first switch 134 and the second switch 135 are in the closed state.

[0042] The RFID tag 132 is carried by the body 126. The support between the RFID tag 132 and the body 126 can be achieved in a variety of ways. In this embodiment, the RFID tag 132 resides within a compartment of the body and is protected by the cover 142 during installation. In this position, the RFID tag 132 is protected from exposure to the fluid flow traveling through the channel 138 and, depending on the particular application, from external sources of contamination. Fig.11As shown, the 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 IC164 can 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 can be electrically coupled to the RFID tag 132 in a series arrangement. In some embodiments, the series arrangement serves to establish a continuous loop with beneficial circuit and detection capabilities. For example, when a continuous loop is not established at one or both of the switches 134, 135, detection of subsequent discontinuities can be easily achieved. In other embodiments, the electrical coupling between the first and second switches 134, 135 and the RFID tag 132 can be a siring arrangement at the IC164 rather than a series arrangement, so as to achieve the ability to transmit the state of each of the switches 134, 135 independently of each other, such as presented above. In addition, as previously referred to Figure 3 described in Figures 5 to 11 In some embodiments, the fluid line connector 112 may include more than one RFID tag.

[0043] exist Figures 5 to 11 In alternative embodiments of the present invention, the fluid line connector 112 may be provided 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. The third [iii)] alternative is depicted in the drawings, but a person skilled in the art can easily conceive of the first [i)] alternative and the second [ii)] alternative by removing the others from the fluid line connector 112 in the drawings.

[0044] Now go to Fig.10, the first switch 134 and the second switch 135 are electrically coupled to the RFID tag 132 so as to transmit their states to the RFID tag 132 based on the impact and non-impact of the switches 134 and 135 by the first actuator member 136 and the second actuator member 137. The electrical coupling can be in the form of a wire 175 spanning from the first switch 134 and the second switch 135 to the RFID tag 132. The wiring can establish a series arrangement. In the example of the wire 175, among other possibilities, the wire 175 can also be routed through one or more grooves present in the body 126, or can be embedded in the wall of the body. In some cases, depending on the design and construction of the RFID tag interacting with the switch and the additional actuator member, in various embodiments, the first switch 134 and the second switch 135 can take various forms. Relative to each other and in embodiments having both switches 134 and 135, the first switch 134 and the second switch 135 can take different forms. In Fig.10 , the first switch 134 and the second switch 135 are in the form of a button 166. When struck and physically pressed by a specific actuator member, the button 166 is in a closed state. And when not struck and physically pressed by a specific actuator member, the button 166 is in an open state.

[0045] The first actuator member 136 and the second actuator member 137 receive abutment in the fully tightening action and when fully tightened between the fluid line connector 112 and the connector 114, thereby being actuated and then striking the first switch 134 and the second switch 135, respectively, to close the switches. In some cases, depending on the design and construction of the specific switches and connectors, in different embodiments, the first actuator member 136 and the second actuator member 137 can have various designs, constructions, and components. Relative to each other and in embodiments having both actuator members 136, 137, the first actuator member 136 and the second actuator member 137 can take different forms.

[0046] In the embodiments of the drawings and now turning to Figure 5 , Figure 8 and Fig.10, the first actuator member 136 is intended to help detect the axial insertion of the connector 114 into the fluid line connector 112. The first actuator member 136 is located near the entrance 163 of the passage 138. Typically, the first actuator member 136 resembles a V-shape turned on its side. In assembly, the longitudinal extension 177 of the first actuator member 136 is generally arranged in-line with the insertion direction 179 of the connector 114 into the fluid line connector 112. The longitudinal extension 177 is generally aligned with the axis of the passage 138 at the entrance 163. The first actuator member 136 has a base 181 and an additional portion 183 that cantilevers from the base 181. The base 181 carries the first switch 134 and is inserted and received in the first socket 159 of the body 126. When the first actuator member 136 receives abutment from the connector 114, the additional portion 183 can move relative to the base 181 on an arcuate path 185. Figure 5 As best shown, prior to insertion of the connector 114, the attachment 183 partially overhangs within the channel 138 so that the ramp 119 of the connector can abut against the attachment 183 upon said insertion. When the attachment 183 is at rest and when the attachment has no abutment from the ramp 119, it remains in this extended and overhanging 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 attachment 183 then moves toward the base 181 and strikes the first switch 134, which constitutes the actuated state of the first actuator member 136 and the corresponding closed state of the first switch 134.

[0047] At one side, the additional part 183 has an outer working surface 187, which is kept generally facing the channel 138 and the connector 114. On its opposite side, the additional part 183 has an inner working surface 189, which is kept generally facing the first switch 134. A projection 191 can extend from the inner working surface 189 for directly hitting the first switch 134. The additional part 183 has a proximal end 193 and has a distal end 195, about which the additional part 183 is bent relative to the base 181. The proximal end 193 acts as a hinge, and the distal end 195 constitutes the free end of the additional part 183. For the first actuator member 136, the axis 197 of the hinge is located in an arrangement that is generally orthogonal to the insertion direction 179 of the connector 114 into the fluid line connector 112, and similarly, is generally orthogonal to the axis of the channel 138 at the inlet 163.

[0048] In this embodiment, the second actuator member 137 has a similar design and construction as the first actuator member 136. Fig. 9, the second actuator member 137 is intended to help detect proper positioning of the retainer 129 and the concomitant reception of the legs 169, 171 in the slot 117. The second actuator member 137 is located at a position outside the passage 138 and at one side of the body wall; however, in other embodiments not depicted, the second actuator member can be located inside the body 126 and need not be outside. Due to its location, and unlike the first actuator member 136, the longitudinal extension 177 of the second actuator member 137 is arranged generally transverse to the insertion direction 179 of the connector 114 into the fluid line connector 112. The longitudinal extension 177 is generally orthogonal to the axis of the passage 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 attachment 183 is positioned at the exterior of the body, with its distal end 195 being at the intersection with the path that the end leg 173 descends and exists when the holder 129 is in its first and third use positions. In this way, when the legs 169, 171 move in the slot 117, the end leg 173 can abut against the attachment 183 and thus can cause actuation of the second actuator member 137. Fig. 9 17 , the actuation of the second actuator member 137 via abutment from the end leg 173 is shown. When the additional part 183 is at rest and when the additional part has no abutment from the end leg 173, it remains in its extended position, which constitutes the non-actuated state of the second actuator member 137 and the corresponding open state of the second switch 135. When the holder 129 is in its second use position, the additional part 183 has no abutment from the end leg 173. When abutted by the end leg 173, the additional part 183 then moves towards the base 181 and strikes the second switch 135, which constitutes the actuated state of the second actuator member 137 and the corresponding closed state of the second switch 135. For the second actuator member 137, the axis 197 of the hinge is generally arranged in line with the insertion direction 179 of the connector 114 into the fluid line connector 112, and similarly, is generally aligned with the axis of the channel 138 at the inlet 163.

[0049] Embodiments of the fluid line connector 112 that employ both switches 134, 135 and actuator members 136, 137 provide enhanced resolution of full tightening and eliminate false-negative detection readings. Figure 6, a first bar schematic 200 represents the state of the first switch 134 when the connector 114 is inserted to a certain axial insertion depth in the fluid line connector 112, and a second bar schematic 202 represents the state of the second switch 135 when the connector 114 is inserted to the same axial depth in the fluid line connector 112. The first bar schematic 200 and the second bar schematic 202 are examples and may be different in other embodiments. Figure 6, the first bar graph 200 and the second bar graph 202 are placed next to the connector 114 and parallel to the axis of the connector 114 to serve as representations of corresponding axial portions of the connector 114 when the connector is inserted into the fluid line connector 112 and the two overlap axially. Although not required 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, as the connector 114 is inserted into the fluid line connector 112 to a first axial insertion depth 204 (or initial axial insertion depth), the first switch 134 should be in its open state. As the connector 114 is inserted into the fluid line connector 112 to a first axial insertion depth 206, the second switch 135 can be in its closed state. Further, as the connector is inserted into the second axial insertion depth 208 (or intermediate axial insertion depth), the state of the first switch 134 can be indeterminate, or the first switch 134 can be in its closed state. As shown, at the second axial insertion depth 208, the retainer 129 now begins to engage with the ramp 119, and the additional portion 183 of the first actuator member 136 is abutted by the ramp 119 or by the extension 115. With the second axial insertion depth 209, the state of the second switch 135 can be indeterminate, or can be closed. With the third axial insertion depth 210, the second switch 135 should be in its open state. Here again, in the second axial insertion depth 210, the ramp 119 engages the retainer 129. Finally, with the third axial insertion depth 212 (or the final axial insertion depth), the first switch 134 should be in its closed state. And with 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 groove 117, and the fluid line connector 112 and the connector 114 are completely fastened together. Moreover, at the third axial insertion depth 212 and the fourth axial depth 214, the first actuator member 136 and the second actuator member 137 are actuated and strike the first switch 134 and the second switch 135. After the connector 114 is moved and inserted into the fluid line connector 112, in this embodiment, the first switch 134 travels from its open state to an indeterminate state, and to its closed state; while the second switch 135 travels 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 acts like a momentary switch and is in its closed state only when struck by the second actuator member 137.Furthermore, false negative detection readings are eliminated 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 and the second switch 135 remains in its open state until the third axial insertion depth 212 and the fourth axial insertion depth 214.

[0050] However, for Figures 5 to 11 In one alternative, the impact from the first actuator member 136 and the second actuator member 137 changes the state of the corresponding first switch 134 and the second switch 135, for example, bringing the switch from an initial open state to a subsequent closed state via the impact, or conversely, bringing the switch from an initial closed state to a subsequent open state via the impact. In another alternative, the first switch 134 itself can receive abutment from the connector 114, wherein the first actuator member 136 is indirectly acted upon and indirectly moved via the abutment of the first switch 134.

[0051] Reference now Fig.12 and 13 , presents another embodiment of a fluid line connector and assembly 310. This embodiment is similar to Figures 1 to 4 Embodiments and Figures 5 to 11 The embodiments have some similarities and Fig.12 and Fig.13 Similarities may not be repeated in the description of the embodiments. 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 feature for easy connection and disconnection action with the connector 314 and is used to connect automotive fluid lines and other fluid lines in other applications together. In this embodiment, the fluid line connector 312 is a female connector and the connector 314 is a male connector (commonly called a socket). As shown in FIG. Fig.12 and Fig.13 As shown, the fluid line connector 312 receives the insertion of the connector 314. The fluid line connector 312 has an elbow and L-shaped configuration in the figures, but can have a straight and coaxial configuration in other embodiments. In many possibilities, the connector 314 can be an integral and somewhat unitary part of a larger component (such as a vehicle battery tray or a heat exchanger), or can be an integral and somewhat unitary part of a fluid line.

[0052] With particular reference Fig.13, the connector 314 in this embodiment has a ramp 319 and a slot 317. The ramp 319 exists at a distance from the end portion 321, but is closer to the end portion 321 than the slot 317. The ramp 319 establishes an increased diameter at the exterior of the connector 314. As explained below, the slot 317 receives the insertion of the retainer of the fluid line connector 312. The slot 317 spans circumferentially around the connector 314.

[0053] In different embodiments, the fluid line connector 312 can have various designs, configurations, and components. Fig.12 and 13 In the illustrated embodiment, 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 an actuator member 336; however, in other embodiments, the fluid line connector 312 may have more, fewer, and / or different components. Fig.13 , the body 326 has a channel 338 defined in its structure for allowing fluid to flow through the fluid line connector 312. An insert assembly can be provided at the interior of the fluid line connector 312 and within the channel 338. Depending on its design and construction, the insert assembly can facilitate matching, receiving and / or sealing between the fluid line connector 312 and the connector 314. Here, in an embodiment, the insert assembly includes an O-ring 345. In addition, the body 326 has such a construction that it cooperates with the retainer 329 to provide a quick connection function of the 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 lead to the passage 338. At the exterior of the wall, there are first and second recesses 353, 355 (also not visible) for temporarily deploying the retainer 329. A flange 357 protrudes radially outward from the body wall and partially encloses portions of the retainer 129 to prevent accidental removal of the retainer 129 when the retainer 129 is received in the groove 117. In order to accommodate the utilization of the actuator member 36, a passage 334 is defined in the body wall and spans completely through the body wall and leads to the passage 338. The actuator member 336 is accessible at the passage 338 via the passage 344. The actuator member 336 is present in the passage 344 and travels through the passage 344. As shown by Fig.13 As shown, the passageway 344 is located near the end of the body 326 that receives the insertion of the connector 314 so that the actuator member 336 can interact with the connector 314 as explained below.

[0054] The cover 342 is carried by the body 326 and partially or more encloses the RFID tag 332 to protect the RFID tag 332 from exposure to foreign objects or things during use of the fluid line connector 312. The cover 342 can have a variety of designs and configurations. In this embodiment, when in the proper position, the cover 342 is located at the outer boundary of the body 326 and completely encloses the RFID tag 332. In order to attach to the body 326, the cover 342 has a pair of extensions 343 (on each side of its structure) disposed on each side of the cover 342. Fig.12 344 ), which snaps onto interconnected structures on the body 326, thereby establishing attachment thereto. In addition, and as also described below, in the embodiment presented here, the actuator member 336 is an integral structure of the cover 342. The actuator member 336 extends uniformly from the front end 345 of the cover 342. Here, the actuator member 336 extends at the outer periphery 347 of the cover 342. This configuration facilitates assembly and installation of the actuator member 336 because when the cover 342 is attached to the body 326, the actuator member 336 is carried by the cover 342 and is received in the passage 344. However, in other embodiments, the cover 342 and the actuator member 336 need not exhibit the integral construction set forth herein.

[0055] The retainer 329 interacts with the body 326 to provide a quick connect function of the fluid line connector 312 so that the connector 314 can be easily inserted and retained in the fluid line connector 312 and can be released and removed as needed or desired. The retainer 329 can vary in design and construction. With particular reference to Fig.12 In this embodiment, the retainer 329 is an integral stainless steel wire spring that is biased inwardly. 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 can be substantially similar in shape and size. In the first use position, the retainer 329 is carried by the body 326, and the first and second legs 369 are moved through the first and second openings 349. The first and second legs 369 are partially present in 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, the connector 314 is in the process of being inserted into the fluid line connector 312, and the ramp 319 engages the first and second legs 369. This engagement pushes the first and second legs 369 away from each other (i.e., radially outward) and separates, and can 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 secured position) in which the retainer 329 is received in the slot 317. Fig.12and Fig.13 317. The first and second legs 369 ride on the ramp 319 and can snap back into position in their first use position, but are now received in the slot 317. The first and second legs 369 move through the first and second openings 349, respectively. The first and second legs 369 being received in the slot 317 secures the fluid line connector 312 and the connector 314 together. Movement of the retainer 329 between its first use position, the second use position, and the third use position causes the retainer 329 to be generally transverse and orthogonal to the insertion direction 379 (in which the connector 314 is inserted into the fluid line connector 312) and the third use position. Fig.13 ), in other words, the movement of the retainer is generally radially outward and radially inward, or upward and downward). When the maintenance personnel pulls the retainer 129 upward to release and remove the connector 114 from the fluid pipeline connector 112, the end foot 173 ( Fig. 9 ) can be seated in the first recess 153, and similarly, the end foot (not specifically depicted) of the second leg 171 can be seated in the second recess 155.

[0056] The RFID tag 332 assists in detecting the proper and complete tightening between the fluid line connector 312 and the connector 314. The RFID tag 332 and the RFID interrogator or reader 356 ( Fig.12 ) communication. 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, proper and complete fastening detection is performed by using RFID technology. In a manufacturing facility, for example, the RFID interrogator 356 can be placed in an assembly, inspection, and / or installation production line, and an interrogation zone can be established in which the RFID interrogator 356 seeks to communicate with the RFID tag 332 as the fluid line connectors and components 310 and larger applications are transported through the fastening area. Depending on the manufacturing facility, the RFID interrogator 356 can establish an interrogation zone that spans several meters from the RFID interrogator 356. In another setting or just another example, the RFID interrogator 356 can be a mobile device (such as a handheld device).

[0057] In this embodiment, the RFID tag 332 is a passive RFID tag type, but can be another type, such as an active RFID tag. The communication received from the RFID tag 332 can transmit various data and information to the RFID interrogator 356. In an embodiment, the transmitted information can be an indication of the fastening state between the fluid line connector 312 and the connector 314. For example, when the fluid line connector 312 and the connector 314 show complete fastening, the RFID tag 332 can transmit the complete fastening information to the RFID interrogator 356 in the form of an ON signal. And conversely, when the fluid line connector 312 and the connector 314 are not completely fastened, the RFID tag 332 can transmit the incomplete fastening information to the RFID interrogator 356 in the form of an OFF signal. Then, the RFID interrogator 356 can process the transmitted information. The transmitted information can also include a part serial number, an installed location, a date of installation, etc.

[0058] The RFID tag 332 is carried by the body 326. The support between the RFID tag 332 and the body 326 can be achieved in a variety of ways. In this embodiment, the RFID tag 332 is located at the outer boundary of the body and is protected by the cover 342 during installation. In this position, the RFID tag 332 is protected from exposure to the fluid flow traveling through the channel 338 and is protected from external sources of contamination depending on the specific application. The RFID tag 332 can have a Fig.11 The RFID tag 332 may be of a design similar to that presented in the present invention and may therefore have an antenna and an integrated circuit (IC) that stores data and information, among other possible functions. The antenna and IC may be present on a substrate of the RFID tag 332. Of course, the RFID tag 332 may have ... Fig.11 The design is different from other designs.

[0059] Now go to Fig.13 , the switch 334 is electrically coupled to the RFID tag 332 so as to transmit its state to the RFID tag 332 based on the impact or non-impact of the switch 334 by the actuator member 336. The electrical coupling can be in the form of wiring. In this embodiment, the switch 334 is directly mounted to the RFID tag 332 and is carried by it. Fig.13 As shown, the switch 334 is carried at a position on the RFID tag 332 such that the switch 334 is physically clamped by the actuator member 336 during assembly. Fig.13 In the orientation of , switch 334 resides on the underside of RFID tag 332. In some cases, switch 334 may take various forms in various embodiments, depending on the design and construction of the RFID tag and the attached actuator components that interact with the switch. Fig.13, the switch 334 is in the form of a button 366. When struck and physically pressed by the actuator member 336, the button 366 is in a closed state. And when not struck and physically pressed by the actuator member 336, the button 366 is in an open state.

[0060] The actuator member 336 is used to impact the switch 334 and change its state (e.g., from an open state to a closed state, or vice versa) when actuated. In this embodiment, the actuator member 336 is actuated and impacts the switch 334 only when two actions occur: a) the connector 314 is inserted into the fluid pipeline connector 312, and b) the retainer 329 is moved to its secured position. If there is no or missing one of these two actions, the actuator member 336 remains unactuated and the switch is not impacted. In some cases, depending on the design and construction of the specific switch and connector, in different embodiments, the actuator member 336 can have various designs, constructions, and components. Fig.12 and 13 In the embodiment of and as previously described, the actuator member 336 is an integral extension of the cover 342. Fig.13 As shown, in assembly and installation, the actuator member 336 is received in the passage 344. In this position, the actuator member 336 partially overhangs within the passage 338 to receive abutment from the connector 314 when the connector 314 is in the process of being inserted into the fluid line connector 312, and is partially exposed to the exterior of the body 326 to receive abutment from the retainer 329. The actuator member 336 is located near the entrance 363 of the passage 338. The longitudinal extension 377 of the actuator member 336 is arranged generally in line with the insertion direction 379.

[0061] In this embodiment, the actuator member 336 has a base 381 and an additional portion 383 that cantilevers from the base 381. Generally, the base 381 is located outside the channel 338 and faces the retainer 329, while the additional portion 383 is located at the channel 338 and partially cantilevers therein, and faces the connector 314. With respect to the switch 334, the base 381 is located on its radially outer side, and the additional portion 383 is located on its opposite radially inner side. In this way, the switch 334 is clamped by the actuator member 336, and the actuator member 336 can press the switch 334 at each side. The base 381 spans (extends) directly and immediately from the cover 342, and the additional portion 383 spans (extends) directly and immediately from the base 381.

[0062] The first extension 385 joins the cover 342 and the base 381, and the second extension 387 joins the base 381 and the attachment 383. The second extension 387 has a bend therein and wraps the actuator member 336 around the edge of the RFID tag 332 and relative to the Fig.13 The additional portion 383 is positioned below the base 381 in the orientation. Opposite the second extension 387, the additional portion 383 has a terminal and free end 388 ( Fig.13 ). The base 381 has a first working surface 389 that directly faces the retainer 329 for abutment therewith, and the attachment 383 has a second working surface 391 that faces the connector 314 for abutment therewith. The first working surface 389 is generally directed radially outward, and the second working surface 391 is generally directed radially inward. The first working surface 389 receives abutment from the retainer 329, and the second working surface 391 receives abutment from the connector 314. The curved seat 393 ( Fig.13 ) is present at the base 381 to receive and rest the bridge 373 of the retainer 329 when the retainer 329 is brought to its fastening position. Opposite to the second working surface 391, the additional part 383 has an inner working surface 392, which is generally facing the switch 334 for directly impacting against it.

[0063] As described in more detail below, during the insertion of the connector 314 into the fluid line connector 312 and the tightening of the retainer 329, the actuator member 336 undergoes movement. To facilitate the movement of the actuator member, a first articulated end 395 is present at the first extension 385 and a second articulated end 397 is present at the second extension 387. In this embodiment, the first articulated end 395 is a wall portion that is thinned relative to the thickness of the wall portion immediately surrounding it. The first articulated end 395 defines a first axis 399 ( Fig.12 ). A portion of the movement of the actuator member may involve deflection and displacement of the base 381 relative to the cover 342 about the first hinged end 395 and about the first axis 399. Similar to the first hinged end 395, the second hinged end 397 defines a second axis 401 ( Fig.12 ). Another part of the movement of the actuator member may involve deflection and displacement of the attachment portion 383 relative to the base 381 about the second hinged end 397 and about the second axis 401. In this embodiment, the first axis 399 and the second axis 401 are parallel to each other and are arranged generally orthogonally relative to the insertion direction 379.

[0064] exist Fig.12 and 13In the embodiment of , the actuator member 336 is actuated and strikes the switch 334 only when the following occur simultaneously: i) the connector 314 is fully and completely inserted into the fluid line connector 312, and ii) the retainer 329 is finally and completely moved to its secured position. Fig.12 and 13 3) and ii). In the absence of one of the two conditions i) or ii), or both conditions i) and ii), the actuator member 336 is not actuated and the switch 334 is not struck. Therefore, the switch 334 changes its state only when both conditions i) and ii) are met, and further, the fluid line connector 312 indicates proper and complete tightening only when both conditions i) and ii) are met. As shown and unlike previous methods, the fluid line connector 312 adopts the use of a single switch and a single actuator member to provide detection of two conditions (condition of the connector 314 [i.e., i)] and condition of the retainer 329 [i.e., ii)]).

[0065] During use of the fluid line connector 312, the connector 314 is inserted into the fluid line connector 312, and the ramp portion 319 abuts against the attachment portion 383. The second working surface 391 is in direct contact with the outer surface of the ramp portion. A first force is applied from the ramp portion 319 to the attachment portion 383. The first force is generally transverse to the insertion direction 379. In response, and as Fig.13 As shown, when the connector 314 reaches its full insertion depth, both the attachment 383 and the base 381 can undergo some degree of movement (the retainer 329 is not in its fastening position, and the movement of the attachment 383 and the base 381 will not cause the impact of the switch 34). The attachment 383 moves along an arcuate path relative to the base 381 and around the second axis 401. On the other hand, in response to the movement of the attachment, the base 381 moves slightly outside relative to the cover 342 and around the first axis 401. The movement of the base 381 occurs, and in a sense, the movement of the base 381 is allowed because the retainer 329 is not in its fastening position. In fact, the movement of the base 381 prevents the impact of the switch 334 in advance. When the retainer 329 moves to its fastening position and the legs 369 are received in the slot 317, the retainer 329 abuts against the base 381. The first working 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. Similar to the first force, the second force is generally transverse to the insertion direction 379. The second force has a direction generally opposite to the direction of the first force. In this regard, the first force and the second force act as an action and reaction force to each other. In response, the base 381 moves inwardly relative to the cover 342 and about the first axis 401 and moves to Fig.13This movement and the opposing application of the first and second forces causes the actuator member 336 to enter its actuated state, and the actuator member 336 strikes and presses the switch 334. The striking of the switch 334 is a result of being clamped between the base 381 and the attachment 383 and between the first and second forces.
