Description

Technical Field

[0001] Cross - reference to Related Applications This application claims the benefit of U.S. Patent Application No. 63 / 499997, filed May 4, 2023, under Articles 4 and 8 of the Stockholm Revision of the Paris Convention for the Protection of Industrial Property, which is hereby incorporated by reference in its entirety.

[0002] This disclosure relates to electrical connectors, particularly to electrical connection assemblies that include radio - frequency identification (RFID) tags for connection verification.

Background Art

[0003] An electrical connector is an electromechanical device used to create an electrical connection between components of an electrical circuit or between different electrical circuits and couple them into a larger circuit. Most electrical connectors have a male and female distinction (the male component, called a plug, is connected to the female component, or socket). The connection methods vary, such as removable ones (for portable devices etc.), those that require tools for assembly or disassembly, or those that provide a permanent electrical junction between two points. Adapters can be used for joining different types of connectors. Electrical connectors can be used not only for power applications but also for data, audio - visual applications, etc.

[0004] In automotive applications, wire harness connection blocks or electrical connection assemblies are used to connect various circuits (such as an ignition system including a starter, dashboard lights, instruments, radio, tail lamps, wipers, direction indicators, heaters, air conditioners, electric fuel pumps, etc.) to a power source or multiple power sources. However, in current designs, the connections are difficult, and if these electrical connection assemblies cannot be properly connected, the vehicle may not start.

[0011] This disclosure relates to one or more exemplary embodiments of an electrical connection assembly.

[0012] In an exemplary embodiment, the electrical connection assembly comprises: a first connector including an engaging portion, a first surface having a plurality of sockets, and a plurality of first wires connected to the plurality of sockets; a second connector including a hole configured to engage with the engaging portion, a plurality of terminals, and a plurality of second wires connected to the plurality of terminals; an RFID assembly connected to one of the first and second connectors, comprising an RFID tag, a first contact electrically connected to the RFID tag, and a second contact electrically connected to the RFID tag and spaced apart from the first contact; and a lock handle pivotably connected to the other of the first and second connectors, configured to lock the second connector to the first connector, wherein in the unconnected state, the lock handle is not engaged with the first and second contacts, and in the connected state, the lock handle is engaged with the first and second contacts.

[0013] In an exemplary embodiment, the lock handle comprises a conductive contact assembly configured to electrically connect a first contact and a second contact when connected. In an exemplary embodiment, the conductive contact assembly comprises a conductor that at least partially surrounds the lock handle. In an exemplary embodiment, the conductive contact further comprises a tab extending radially outward from the conductor. In an exemplary embodiment, the conductive contact assembly comprises a first conductor portion extending radially outward from the lock handle and configured to engage with the first contact, and a second conductor portion extending radially outward from the lock handle and configured to engage with the second contact. In an exemplary embodiment, the conductive contact assembly further comprises a third conductor portion connecting the first and second conductor portions, the third conductor portion being embedded within the lock handle.

[0014] This disclosure relates to one or more exemplary embodiments of an electrical connection assembly, such as an automotive electrical connection box. The connection box comprises a female component and a male component. In the exemplary embodiment, the female component comprises a locking handle. The male component engages with the female component, at which point the locking handle is pulled down onto the male component. In the exemplary embodiment, the handle is part of the female component, but the handle may be part of the male component. The male component has a flange, an RFID tag is located near the flange, and electrical terminals are located on or near the flange. The handle has a conductive component, and when fully locked, the conductive component makes contact with both electrical terminals to complete the RFID tag circuit, thereby changing the RFID tag's read state from "open" to "closed". An "open" read indicates an unlocked or disconnected state, and a "closed" read indicates a locked or connected state.

[0015] This disclosure relates to one or more embodiments of a wire harness connecting block assembly that provides clear identification of when a lock handle is fully closed during a manufacturing assembly process, thereby indicating a proper or complete connection. In an exemplary embodiment, the wire harness connecting block assembly includes an RFID tag that indicates a first state (e.g., an off signal) when the handle is not fully closed and a second state (e.g., an on signal) when the handle is fully closed.

[0016] In an exemplary embodiment, the electrical connection assembly provides the user with clear identification that the wire harness connection block is properly closed, preventing, for example, a vehicle from failing to start. In an exemplary embodiment, the electrical connection assembly provides feedback signals (e.g., via an RFID tag) that can be read by a user or a computer program, indicating the state and state changes. When a computer program is used, the electrical connection assembly eliminates the need for human intervention to detect the connection state. In an exemplary embodiment, the RFID tag is located in the housing of the connection box, and when the lock handle touches the terminals of the RFID tag, the circuit of the RFID tag is closed, i.e., engaged (i.e., indicating that the electrical connection assembly is connected). When the lock handle is not touching the terminals of the RFID tag, the circuit of the RFID tag is open (i.e., indicating that the electrical connection assembly is disconnected). In an exemplary embodiment, if the lock handle is not in the fully closed position, the RFID tag is read as "open," and if the lock handle is in the fully closed position, the RFID tag is read as "closed."

[0045] Referring here to the drawings, Figure 1A is a front perspective view of the electrical connection assembly 10 in a disconnected state. Figure 1B is a front view of the electrical connection assembly 10 in a disconnected state. Figure 1C is a front perspective view of the electrical connection assembly 10 in a connected state. Figure 2 is an exploded front perspective view of the electrical connection assembly 10. The electrical connection assembly 10 comprises a component or connector 20 and a component or connector 90. In an exemplary embodiment, the electrical connection assembly 10 further comprises a locking handle 130 connected to one of the connectors 20 and 90. The locking handle 130 is configured to lock the connector 20 to the connector 90. In an exemplary embodiment, the electrical connection assembly 10 further comprises an RFID assembly 60. The electrical connection assembly 10 is configured to connect electrical conductors or data cables (e.g., coaxial cables, fiber optic cables, twisted pair cables, etc.) for transmitting power and / or data between circuits. For example, the electrical connection assembly 10 is configured to connect wire 52 to wire 140.

[0046] Figure 3A is a rear view of connector 20. Figure 3B is a side view of connector 20. In an exemplary embodiment, as shown, connector 20 is a male connector and connector 90 is a female connector. In such an exemplary embodiment, connector 20 includes an engaging portion 21 configured to engage with a hole 114 of connector 90. However, it should be noted that in the exemplary embodiment, connector 90 is a male connector and connector 20 is a female connector. Connector 20 includes a rear surface 22, a front surface 24, a side surface 26A, a side surface 26B, a top surface 28A, and a bottom surface 28B. In an exemplary embodiment, the rear surface 22 is a substantially planar surface configured to be connectable to connector 90. Specifically, the rear surface 22 is configured to engage with a surface 124 of insert 120, as will be described in more detail below. The rear surface 22 includes a plurality of holes, ports, or sockets 36 configured to be connectable to conductors or terminals 102. Each hole 36 includes a terminal connected to one of the wires 52. Therefore, when one of the terminals 102 fully engages with one of the holes 36, an electrical or data connection is completed.

[0047] In an exemplary embodiment, the front surface 24 is connected to the rear surface 22 by at least one of the sides 26A, 26B, top surface 28A, and bottom surface 28B. The front surface 24 is configured to be engageable with or accessible to the lock handle 130 when the lock handle 130 is in the deployed position (see Figure 1C). In an exemplary embodiment, the connector 20 further comprises a lip or flange 32 extending substantially axially AD1 from the front surface 24. The flange 32 comprises a surface 34. In an exemplary embodiment, the surface 34 is positioned perpendicular to the front surface 24. The surface 34 is configured to be engageable with the lock handle 130 when the lock handle 130 is in the deployed position, as will be described in more detail below.

[0048] The connector 20 further comprises a hole 30. In an exemplary embodiment, the hole 30 is located on the bottom surface 28B. A wire 52 extends through the hole 30 and connects to a hole 36. In an exemplary embodiment, the wire 52 may be covered by a conduit 50. In an exemplary embodiment, the connector 20 further comprises one or more locking protrusions, for example, locking protrusions 38A to 38B. Locking protrusion 38A extends from the side surface 26A and is located near the back surface 22. Locking protrusion 38B extends from the side surface 26B and is located near the back surface 22. The locking protrusions 38A to 38B are configured to engage with holes 108A to 108B of the connector 90 and grooves 138A to 138B of the locking handle 130, respectively, to secure the connector 20 to the connector 90, as will be described in more detail below.

[0049] In an exemplary embodiment, the connector 20 further comprises a projection 42 extending from the top surface 28A. The projection 42 is configured to engage with a groove 106 of the connector 90 to maintain alignment between the connector 20 and the connector 90 during assembly. In an exemplary embodiment, the connector 20 further comprises one or more channels 40 located on the side surfaces 26A and / or 26B. The channels 40 are configured to maintain alignment between the connector 20 and the connector 90 during assembly.

[0050] Figure 4 is a perspective view of the RFID assembly 60. The RFID assembly 60 generally comprises at least one layer (e.g., an adhesive layer 62 and / or layer 64), an RFID tag 70, and at least one contact (e.g., contact 80A and / or contact 80B). In an exemplary embodiment, the RFID assembly 60 is an RFID label connected to a connector or component, which is configured to connect to another component.

[0051] The adhesive layer 62 is configured to be fixable to the connector 20. In some embodiments, the adhesive layer 62 fixes layer 64 and / or contacts 80A and 80B to the connector 20. It should be noted that layer 64 does not need to be connected to the connector 20 via adhesive (i.e., adhesive layer 62), and may be connected and / or attached using any other suitable means, such as string, tape, hook and loop fasteners, soldering, welding, etc. In some embodiments, the adhesive layer 62 is connected to the front 24 and fixes the RFID assembly 60 to the connector 20. In exemplary embodiments, the adhesive layer 62 is connected to the front 24 and the surface 34 and fixes the RFID assembly 60 to the connector 20, and thus includes a bent or folded portion 68. In exemplary embodiments, the bent portion 68 engages with the surface 34.

[0052] The RFID assembly 60 may further comprise a layer 64. The layer 64 is connected to the upper surface of the adhesive layer 62 and is configured to function as a platform or base for the RFID tags 70 and contacts 80A-B. In exemplary embodiments, the layer 64 comprises ferrite. In exemplary embodiments, the RFID tags 70 and contacts 80A-B are connected directly to the upper surface of the adhesive layer 62 without requiring the layer 64. In exemplary embodiments, the RFID tags 70 and contacts 80A-B are connected directly to the connector body 20, specifically the front 24 and the front 34, respectively, without requiring the adhesive layer 62 or the layer 64. In exemplary embodiments, the RFID assembly 60 further comprises a layer 66. The layer 66 is configured to cover and protect the RFID tags 70. As shown in Figure 4, the layer 66 completely covers the RFID tags 70 and at least partially covers the contacts 80A and 80B. However, at least portions of contacts 80A and 80B, for example, exposed portions 82A and 82B, must be exposed so as to engage with the conductive contact assemblies 150, 250, 350, and 450, as will be described in more detail below. In an exemplary embodiment, the protective layer 66 extends at least partially over the bend portion 68.

[0053] The RFID tag 70 comprises an integrated circuit (IC) or chip 72 and an antenna 74. In exemplary embodiments, the RFID tag 70 is a passive RFID tag. In exemplary embodiments, the RFID tag 70 comprises an active RFID tag (and further comprises a power supply). In exemplary embodiments, the RFID tag 70 is a semi-passive RFID tag. In some embodiments, the RFID tag 70 is pre-programmed to transmit information such as a unique identification number (UID) and the state of the RFID assembly 60 (i.e., open or closed). The antenna 74 is connected via conductors 76A and 76B, with the first end connected to the IC 72 at the antenna radio frequency (RF) input LA and the second end connected to the IC 72 at the antenna RF input LB. The RFID tag 70 is further connected to contacts 80A and 80B. Specifically, conductor 78A connects contact 80A to the IC 72 at the ground pin GND, and conductor 78B connects contact 80B to the IC 72 at the detector pin DP.

[0054] Contact 80A is separated from contact 80B by a gap 84. In exemplary embodiments, as shown, contacts 80A and 80B are located on the bend 68, particularly on the surface 34 of the flange 32. Contacts 80A and 80B are configured to engage with conductive contact assemblies 150, 250, 350, and 450. In exemplary embodiments, contacts 80A and 80B are electrical conductors. Once the connector 20 is properly secured to the connector 90, the lock handle 130 displaces circumferentially in CD1 from the retracted position to the deployed position, locking the connector 20 to the connector 90. Once the electrical connection assembly 10 is fully connected, the conductive contact assemblies 150, 250, 350, and 450 engage with contacts 80A and 80B. For example, as shown in Figure 1C, conductive contact assembly 150 is engaged with contacts 80A and 80B. In exemplary embodiments, conductive contact assemblies 150, 250, 350, and 450 comprise a conductive material (e.g., metal). Thus, the conductive contact assemblies 150, 250, 350, and 450 complete the circuit between contacts 80A and B and IC 72, enabling the RFID tag 70 (i.e., enabling the RFID tag 70 to be powered by an electromagnetic field generated by an external device (not shown)) or switching it to a closed state (from an open state). Before the circuit is completed, i.e., before contact 80B is directly electrically connected to contact 80A, the RFID tag 70 is not enabled (i.e., the RFID tag 70 cannot be powered by an electromagnetic field generated by an external device), or in some embodiments, it is in an open state.

[0055] Once the circuit is complete (i.e., the conductive contact assemblies 150, 250, 350, and 450 directly connect contact 80A and contact 80B), an external device such as an RFID reader (not shown) will detect that the RFID tag 70 is enabled or closed, thereby indicating that the electrical connection assembly 10 is properly connected. In other words, if the RFID tag 70 is enabled, the RFID reader will recognize the presence of the RFID tag 70 and therefore determine that the electrical connection assembly 10 is properly connected. If the circuit is not complete (i.e., contact 80A is not directly connected to contact 80B), the RFID reader will not detect an enabled RFID tag 70 and therefore indicate that the electrical connection assembly 10 is not properly connected. To put it another way, if the RFID tag 70 is disabled, the RFID reader will not recognize the presence of the RFID tag 70 and therefore determine that the electrical connection assembly 10 is not properly connected.

[0056] In an exemplary embodiment, the RFID tag 70 is always activated and detectable and readable by an RFID reader, regardless of whether contacts 80A and 80B are connected. In such an exemplary embodiment, if contacts 80A and 80B are not directly connected, for example, via conductive contact assemblies 150, 250, 350, and 450, the RFID tag 70 can transmit certain information to the RFID reader. Such information includes, but is not limited to, the UID number (e.g., RFID tag, connector, circuit, conduit, wire, etc.), size number, model number, serial number, status of the RFID tag 70 (i.e., open or closed), uniform resource locator (URL), station identification information (i.e., manufacturing lot number), date / time stamp, description, etc. In other words, regardless of whether contacts 80A and 80B are connected, the RFID tag 70 will always transmit certain data (e.g., UID number, status, etc.) as long as it is functioning properly. Therefore, in exemplary embodiments, the RFID tag 70 is pre-programmed to always transmit at least a UID number and a state (i.e., open or closed) using, for example, hexadecimal data or a value. This is important because a user can scan a given RFID tag to determine whether it is functioning properly (i.e., functioning properly if the RFID tag is transmitting data properly) and its current state (i.e., open or closed). If contacts 80A and 80B are connected, for example, via conductive contact assemblies 150, 250, 350, and 450, the RFID tag 70 transmits data indicating a closed state. In some embodiments, the RFID tag 70 indicates a first value (e.g., a first hexadecimal) for an open state and a second value (e.g., a second hexadecimal) for a closed state, the second value being different from the first value. It should be recognized that the RFID tag 70 may include appropriate optional programming to indicate that it is functioning properly and to distinguish between open and closed states, and this disclosure should not be limited to the use of a hexadecimal system only.

[0057] Figure 5A is a front perspective view of the connector 90 with the lock handle 130 in the retracted position. Figure 5B is a front perspective view of the connector 90 with the lock handle 130 in the deployed position. The connector 90 comprises a front 92, a rear 94, a side 96, and a side 98. The connector 90 includes a hole 114 extending axially AD2 from the front 92. The front 94 includes a plurality of holes 100. Wires 140 extend through the holes 100 and are connected to their respective conductors or terminals 102. In an exemplary embodiment, the terminals 102 are rigid and configured to extend through a hole 126 in an insert 120 and engage with a hole 36 in the connector 20, as will be described in more detail below.

[0058] In an exemplary embodiment, the connector 90 includes a projection 104 extending from its surface, for example, the top surface of the connector 90. The projection 104 forms a channel 106, which is configured to engage with a projection 42 to maintain the alignment of the connector 20 and the connector 90 during assembly. In an exemplary embodiment, the connector 90 includes one or more holes, for example, holes 108A to 108B. The holes 108A to 108B are each configured to engage with projections 38A to 38B. Hole 108A is a through hole extending through the side surface 96. In an exemplary embodiment, hole 108A extends through the insert 120. Hole 108B is a through hole extending through the side surface 98. In an exemplary embodiment, hole 108B extends through the insert 120. The projections 38A to 38B are located within the holes 108A to 108B in the connected state and are configured to be secured thereby by a locking handle 130. In an exemplary embodiment, the connector 90 further comprises one or more projections 110. The projections 110 are configured to engage with the channel 40 to maintain the alignment of the connector 20 and the connector 90 during assembly. In an exemplary embodiment, the projections 110 are located within the hole 114 and / or on the insert 120.

[0059] The insert 120 is slidably or translationally connected to the connector 90. Specifically, the insert 120 is positioned within the hole 114 and configured to be displaced axially AD1 and axially AD2 relative to the connector 90. The insert 120 comprises a front surface 122, a face 124, and a hole 126. The hole 126 extends axially AD2 from the front surface 122 and forms the face 124. Thus, the face 124 is recessed relative to the front surface 122. The face 124 comprises a plurality of holes 126 that slidably engage with the terminal 102.

[0060] The insert 120 is connected to the lock handle 130, and when the lock handle 130 is displaced circumferentially relative to the connector 90, the insert 120 is displaced axially relative to the connector 90. For example, when the lock handle 130 is displaced circumferentially CD1 relative to the connector 90, the insert 120 is displaced axially AD2 relative to the connector 90. This causes the terminal 102 to protrude further from the surface 124. Such circumferential displacement of the lock handle 130 also serves to further retract the engaging portion 21 into the connector 90, as will be described in more detail below. When the lock handle 130 is displaced circumferentially CD2 relative to the connector 90, the insert 120 is displaced axially AD1 relative to the connector 90. This action protects the terminal 102, as it does not protrude axially AD1 from the surface 124, or only slightly.

[0061] For example, in the retracted state of the lock handle 130 shown in Figure 5A, the terminal 102 protrudes from the surface 124 by a first amount in the axial direction AD1, and in the deployed state of the lock handle 130 shown in Figure 5B, the terminal 102 protrudes from the surface 124 by a second amount in the axial direction AD1, and the second amount is greater than the first amount. This is due to the axial displacement of the insert 120. Therefore, in the retracted state of the lock handle 130 shown in Figure 5A, the front surface 122 of the insert is substantially aligned with the front surface 92 of the connector 90. In the deployed state of the lock handle 130 shown in Figure 5B, the front surface 122 is separated from the front surface 92 by a space S. Therefore, the terminal 102 remains fixed to the connector 90, and the insert 120 is displaced relative to the connector 90. In an exemplary embodiment, the connector 90 and the insert 120 are provided with at least one projection and at least one channel to maintain alignment when the insert 120 is displaced axially relative to the connector 90.

[0062] The lock handle 130 is pivotably connected to the connector 90. In an exemplary embodiment, the connector 90 comprises one or more pivot connections or pins 112, and the lock handle 130 comprises one or more pivot connections or holes 132 that engage with the pins 112. However, it should be noted that the lock handle 130 may comprise pins and the connector 90 may comprise holes. The lock handle 130 comprises at least one arm, e.g., arms 134A to 134B, pivotally connected to the connector 90. Arm 134A is pivotally connected to a side 96 at its proximal end, and arm 134B is pivotally connected to a side 98 at its proximal end. A support member 136 is connected and coupled between the distal ends of arms 134A to 134B.

[0063] Arm 134A has a groove 138A configured to engage with a projection 38A of the connector 20. As best shown in Figure 1A, when the handle 30 is retracted, the groove 138A and the hole 108A are aligned, and the projection 38A can be inserted therein. Then, when the lock handle 130 is displaced in the circumferential direction CD1, the surface of the groove 138A engages with the projection 38A, pulling the projection 38A axially AD2 into the hole 108A, and finally locking it in place as shown in Figure 1C. Similarly, arm 134B has a groove 138B configured to engage with a projection 38B of the connector 20. When the handle 30 is retracted, the groove 138B and the hole 108B are aligned, and the projection 38B can be inserted therein. Subsequently, when the lock handle 130 is displaced in the circumferential direction CD1, the surface of the groove 138B engages with the projection 38B, pulling the projection 38B in the axial direction AD2 into the depths of the hole 108B, and finally locking it in place.

[0064] The lock handle 130 further comprises conductive contact assemblies, e.g., conductive contact assemblies 150, 250, 350, 450, configured to engage with the surface 134, specifically the contacts 80A-80B, to confirm a secure connection. For example, in an exemplary embodiment, the lock handle 130 comprises a conductive contact assembly 150, e.g., a strip of foil tape. The conductive contact assembly 150 comprises a tubular conductor that at least partially surrounds (i.e., wraps around) the support material 136. As shown in Figure 1C, when the lock handle 130 is in the deployed position, the conductive contact assembly 150 engages with both contacts 80A-80B (e.g., located on the surface 34), completing or closing the circuit of the RFID assembly 60 and indicating that the electrical connection assembly 10 is connected as described above. If the lock handle 130 is not in the deployed position, for example as shown in Figures 1A-1B, the conductive contact assembly 150 will not engage with contacts 80A-80B, the circuit of the RFID assembly 60 will remain incomplete or open, and the electrical connection assembly 10 will be disconnected.

[0065] Therefore, the lock handle 30 has the following multiple functions: 1) Displace the insert 120 axially relative to the connector 90, and thus expose more or less of the terminal 102. 2) Engage and retract the protrusions 38A~38B to further insert the connector 20 into the connector 90. 3) Secure the protrusions 38A~38B in the holes 108A~108B to lock the connector 20 into the connector 90. 4) Engage the RFID assembly 60 to confirm proper connection.

[0066] To assemble the electrical connection assembly 10, the lock handle 130 is displaced to its retracted position, for example, as shown in Figure 1A. The engaging portion 21 of the connector 20 is inserted into holes 114 and 128 such that the protrusions 38A to 38B are aligned with holes 108A to 108B and grooves 138A to 138B, respectively. Furthermore, the channel 40 is aligned with projection 110 and projection 42 is aligned with channel 106. Once fully inserted, the back surface 22 engages with and / or is positioned close to and / or abuts against surface 124. Next, the lock handle 130 is displaced in the circumferential direction CD1, thereby displacing the insert 120 axially AD2 relative to the connector 90, as described above, and the protrusions 38A to 38B, and thus the engaging portion 21, are further drawn into the connector 90 axially AD2, and the terminal 102 engages with hole 36. When the lock handle 130 is in the deployed position, for example as shown in Figure 1C, terminal 102 fully engages with hole 36, thereby establishing a connection between wire 140 and wire 52, protrusions 38A-38B are locked into holes 108-108B, conductive contact assemblies 150, 250, 350, 450 engage with contacts 80A-80B, and RFID assembly 60 indicates the connected state (see Figure 1C). To disassemble the electrical connection assembly 10, the lock handle 130 is displaced circumferentially in the CD2 direction to return it to the retracted position, and connector 90 is removed from connector 20.

[0067] Figure 6 is a partial front perspective view of the electrical connection assembly 10 in a connected state. Figure 7 is a detailed view of the electrical connection assembly 10, generally following detail 7 of Figure 6. In an exemplary embodiment, the lock handle 130 comprises a conductive contact assembly 250. The conductive contact assembly 250 comprises a portion 252 and a portion or tab 254. The portion 252 at least partially encloses the support member 136 and is configured to connect the conductive contact assembly 250 to the handle 130. The tab 254 is connected to the portion 252 and extends radially outward from the support member 136. In an exemplary embodiment, the radially outward positioning of the tab 254 fills the gap between the lock handle 130 and the flange 32 in the connected state. When the lock handle 130 is in the deployed position, the conductive contact assembly 250, specifically the radially outward-extending tab 254, engages with both contacts 80A-80B (for example, located on surface 34), completing or closing the circuit of the RFID assembly 60 and indicating that the electrical connection assembly 10 is connected as described above. When the lock handle 130 is not in the deployed position, the conductive contact assembly 250 does not engage with contacts 80A-80B, the circuit of the RFID assembly 60 remains incomplete or open, and indicating that the electrical connection assembly 10 is disconnected.

In an exemplary embodiment, the portion 354 is spaced apart from the portion 352 along the support member 136. The portion 354 is electrically connected to the portion 352 via the portion 356. The portion 356 is embedded in the support member 136. In an exemplary embodiment, the conductive contact assembly 350 is molded into the lock handle 130. In exemplary embodiments, the conductive contact assembly 350 may have a U-shape. The radially outward arrangement of tabs 352 and 354 fills the gap between the lock handle 130 and the flange 32 in the connected state. When the lock handle 130 is in the deployed position, the conductive contact assembly 350, specifically the radially outward-extending tabs 352 and 354, engage with both contacts 80A-80B (e.g., located on surface 34), completing or closing the circuit of the RFID assembly 60 and indicating that the electrical connection assembly 10 is connected as described above. When the lock handle 130 is not in the deployed position, the conductive contact assembly 350 does not engage with contacts 80A-80B, the circuit of the RFID assembly 60 remains incomplete or open, and indicating that the electrical connection assembly 10 is disconnected.

The portion 456 is embedded in the support member 136. In an exemplary embodiment, the conductive contact assembly 450 is molded into the lock handle 130. In an exemplary embodiment, the conductive contact assembly 450 may have a U-shape. The radially outward positioning of tabs 452 and 454 fills the gap between the lock handle 130 and the flange 32 in the connected state. When the lock handle 130 is in the deployed position, the conductive contact assembly 450, specifically the radially outward-extending terminals or rods 452 and 454, engage with both contacts 80A-80B (for example, located on surface 34), completing or closing the circuit of the RFID assembly 60 and indicating that the electrical connection assembly 10 is connected as described above.
