Description

Technical Field

[0001] This disclosure relates to an electrical connector assembly and a charging socket, particularly an electrical connector assembly and charging socket for charging electric vehicles, for example, in the field of new energy vehicle charging equipment technology. Background Technology

[0002] In the current technology, with the development of science and technology and the increasing awareness of environmental protection, hybrid vehicles and pure electric vehicles are gradually being accepted by consumers. Similar to the refueling cap of traditional fuel vehicles, electric vehicles need to have a charging socket located in a suitable position on the vehicle to connect with an external charging gun, facilitating consumers to replenish the vehicle's power. A charging socket typically includes a charging socket housing, a terminal mounting base, and connecting terminals. The terminal mounting base is fixedly installed in the charging socket housing, and the terminals are installed in the terminal mounting base. One end of the connecting terminal is used to plug into the external charging gun, and the other end is used to crimp a wire to achieve electrical connection. The charging socket housing is fixed to the vehicle's sheet metal. Specifically, to charge an electric vehicle, the charging plug (or charging gun) of the charging station is generally inserted into the charging socket installed on the electric vehicle body.

[0003] The electrical conductors in the charging plug heat up due to unavoidable ohmic resistance. This heating may also heat the charging plug housing. When charging the traction battery pack of an electric vehicle, to increase the charging speed, it is necessary to increase the charging current flowing through the charging plug; or, to meet user needs and reduce charging time, the charging dock is equipped with a fast-charging interface, which needs to withstand higher voltage and larger current for a short period of time. As an example, if the resistance at the crimping point between the wire and the connection terminal increases or there is a short-term overcurrent, a large amount of heat will be generated, causing the temperature at that point to rise sharply. This will cause the temperature of the charging terminals inside the charging dock to rise sharply, posing a significant safety hazard. If the temperature rise is not controlled in time, it may lead to a safety accident, such as burning out the charging dock or other electrical equipment.

[0004] In existing technologies, to control the temperature rise of the charging terminals, a lead frame is typically installed in the charging socket, and a temperature detector is mounted on the lead frame to detect the temperature of the connection terminals. This allows for timely monitoring of the internal temperature of the charging socket, especially the temperature at the point where the wires are crimped with the connection terminals. Based on the detected actual temperature, appropriate measures can be taken to promptly eliminate safety hazards and improve vehicle safety. The temperature detector includes a temperature sensor located near the high-temperature area to be measured (but due to space and size limitations, the temperature sensor often cannot be placed at the highest temperature rise point in the charging socket), and optionally, a heat-conducting component, such as a thermal pad, located outside the temperature sensor. For example, in existing technologies, the temperature sensor needs to be pre-inserted into the thermal pad, and then the thermal pad with the temperature sensor installed is inserted into the mounting slot on the lead frame or electrically connected to the circuit board. This allows the thermal pad to make thermal contact with the charging terminals, and the temperature sensor to be electrically connected to the lead frame or circuit board. Existing temperature detectors have a complex installation structure, are difficult to assemble, costly, and inconvenient to use. Furthermore, the temperature sensor is spaced apart from the connection terminal, allowing heat from the connection terminal to be conducted to the sensor via air. This method of temperature measurement results in inaccurate readings, slow response times, and an inability to promptly address safety hazards. Additionally, in existing technologies, the thermal pad is typically inserted into a mounting slot on the lead frame along the axial direction of the charging terminal. Therefore, in existing technologies, the thermal pad is prone to movement along the axial direction of the charging terminal, which reduces thermal contact performance and affects the timeliness and accuracy of temperature detection.

[0005] Therefore, there is an urgent need in the art for an improved electrical connector assembly and charging socket that adaptively changes the pin arrangement related to the placement of the temperature sensor, taking into account that the aluminum busbar screw portion in the charging socket bus for adapting to the insertion terminal of the power connector is usually the part with the highest internal temperature rise of the charging socket, and more particularly designed to facilitate guiding the pins of the temperature sensor to achieve a different outgoing direction from the axial direction of the bus and / or terminals in conventional technology selections.

Figure 2A and Figure 2B The diagrams are shown below.

[0057] According to a general technical concept of this disclosure, as shown in the figure, an electrical connector assembly 10 suitable for use in the field of electric vehicle charging is provided, including an electrical connection structure 11. As an example, as shown in the figure, the electrical connection structure 11 includes: at least one terminal body 111, for example, the terminal body 111 is a monolithic piece, which may be a straight arrangement extending longitudinally (also known as the length direction) or a bent arrangement extending vertically perpendicular to the longitudinal direction, and has opposing insertion ends 1111 and connection ends 1112; a bus 112, having at least one electrical contact end 1121 (here, as an example, the opposing insertion ends 1111 and connection ends 1112 of the terminal body 111). In terminal 1112, the connecting terminal 1112 is disposed adjacent to the electrical contact terminal 1121 of the bus 112, and the plug-in terminal 1111 is disposed opposite to the electrical contact terminal 1121 of the bus 112; and at least one connector (as an example, a threaded member 113, which typically has external threads) is connected between the corresponding electrical contact terminal 1121 and the connecting terminal 1112 of the corresponding terminal body 111, for example, to establish a conductive connection therebetween. Specifically, as an example, the at least one The at least one threaded member 113 of the connector extends through and presses against both the corresponding electrical contact 1121 and the connection end 1112 of the corresponding terminal body 111 to establish a conductive connection therebetween. The electrical connector assembly 10 also includes at least one temperature sensing component 12, each temperature sensing component 12 comprising: a temperature sensor 121, in thermal contact with the connector, and having at least one pin 1212 extending outward (e.g., vertically away from the threaded member 113); and a guide 122 covering the... The temperature sensor 121 includes a through-hole 1220 located at the top center and a groove 1221 extending continuously (e.g., radially) from the central hole 1220 to a peripheral edge 1222, the groove 1221 being configured to allow at least one pin 1212 to move radially into the central hole 1220. As a specific embodiment, for example, the shape and size of the groove 1221 are determined to receive and guide the at least one pin 1212 radially into place in the central hole 1220.

[0058] Furthermore, for the temperature sensing component 12, in a specific embodiment, as shown in the figure as an example, at least one pin 1212 is arranged to extend from the temperature sensing element 1211 (illustrated as being bent after extension to extend in a plane orthogonal to the vertical direction), and configured to output the electrical signal of the temperature sensor 121.

[0059] With this configuration, the aluminum busbar screw connection at the insertion terminal of the power connector in the busbar 112 of the charging dock 1, which is typically the area with the highest internal temperature rise, is achieved through a simple structural improvement using the existing threaded part 113 feature that screws the busbar 112 (e.g., the aluminum busbar) to the terminal. This allows the temperature sensing module of the temperature sensor 121 to directly abut against the threaded part 113 (e.g., the Phillips or hexagonal notch at its top for screwdriver tightening) at this screw connection to achieve direct heat transfer, reducing heat loss due to redundant heat transfer paths during temperature sensing and achieving more accurate thermal and temperature measurements. Another In this regard, by providing a laterally open slot 1221 on the guide 122 to facilitate the lateral insertion of the pin 1212 from the side, it is possible to simply move the guide 122 toward the pin 1212 after the slot 1221 of the guide 122 is laterally aligned with the pin 1212. This simultaneously allows the guide 122 to cover the temperature sensor 121 and the pin 1212 to move into the hole of the guide 122 via the slot 1221, thus simplifying the operation without having to vertically cover the temperature sensor 121 with the guide 122 and align the hole of the guide 122 with the pin 1212. Thus, through the synergistic effect of these two aspects, it is no longer necessary to set up an additional lead frame and / or printed circuit board for mounting the temperature sensor 121, thereby simplifying the structure; and further facilitating the quick-assembly of the temperature sensing structure that enables real-time sensing of the temperature at the highest temperature rise point within the charging base 1, thus fully detecting the temperature of the charging base 1.

[0060] Regarding the assembly of pin 1212 relative to guide 122, according to an exemplary embodiment of the present disclosure, further, for example as shown, the slot 1221 is configured to extend radially from the central hole 1220 to the peripheral edge 1222 and open at the peripheral edge 1222; and the at least one pin 1212 includes a linearly configured first portion 1212A extending vertically from the temperature sensor 121, the first portion 1212A being configured to move from the peripheral edge 1222 into the central hole 1220. Thus, guide 122 is mounted to and at least partially covers the top of intermediate member 120, and configured to allow pin 1212 of temperature sensor 121 to be led out axially away from the threaded member 113 from intermediate member 120 through the central hole 1220.

[0061] With this specific arrangement, during the process of guiding the guide 122 toward the free end of the pin 1212, it is not necessary to always align the free end of the pin 1212 with the center hole 1220 before inserting the free end of the pin 1212 into the center hole 1220. This facilitates the side insertion of the guide 122 so that the pin 1212 travels through the slot 1221 into the center hole 1220 of the guide 122, achieving convenient side assembly at the boundary.

[0062] As an example, the at least one pin 1212 further includes a second portion 1212B, linearly configured and connected in series with the first portion 1212A and arranged downstream of the first portion 1212A. For example, the first portion 1212A and the second portion 1212B are directly and closely connected to each other in an upstream-downstream relationship on a signal path, and the second portion 1212B is configured to bend at an angle relative to the first portion 1212A in response to force. In a more specific embodiment, for example, in an exemplary embodiment, the second portion 1212B of each pin 1212 is bent at a right angle relative to the first portion 1212A. This ensures that while the first portion 1212A extends vertically, the second portion 1212B extends horizontally, thereby facilitating the horizontal extension of the free end of the pin 1212 in a limited space.

[0063] In a further embodiment, as shown in the figure as an example, the guide 122 also includes two ribs 1223 formed on its top, the two ribs 1223 being arranged substantially parallel to each other and spaced apart by a gap 1224 between them, the gap 1224 being adapted to receive and hold the second portion 1212B. Thus, the bent second portion 1212B of the pin 1212 (e.g., the second portion 1212B extending horizontally) is reliably held in place in the horizontal plane.

[0064] In a further embodiment, as shown in the figure as an example, the two ribs 1223 are parallel to the groove 1221, and the groove 1221 is aligned with the gap 1224. With this arrangement, during the lateral insertion of the guide 122, once the opening of the groove 1221 at its peripheral periphery 1222 has been aligned with the pin 1212, lateral assembly of the guide 122 toward the pin 1212 can begin. This facilitates the simultaneous guidance of the second portion 1212B of the pin 1212 into the gap 1224 defined between the two ribs 1223, as the first portion 1212A of the pin 1212 moves relative to the central hole 1220. This ensures that once the first portion 1212A of the pin 1212 is in place in the central hole 1220, the second portion 1212B of the pin 1212 is also held in place within the gap 1224 defined between the two ribs 1223. This enables convenient quick installation and reliable relative fixed positioning between the bent pin 1212 and the guide 122.

[0065] In an alternative embodiment, as an example, each rib 1223 is configured to project toward the other rib 1223 at its free end; and the lower portions of the two ribs 1223 extend parallel to each other. More specifically, for example, each of the two ribs 1223 is inclined or bent toward the other rib 1223 at its free end, such that the groove 1221 narrows between the free ends of the two ribs 1223. As an example, each rib 1223 is arranged as a cantilever member with an end bent toward the other rib 1223. Thus, the two ribs 1223 are closer to each other at their respective top free ends, making it less likely for the second portion 1212B to disengage vertically from the gap 1224, thereby effectively ensuring that the second portion 1212B of the pin 1212 remains in place vertically as well.

[0066] According to exemplary embodiments of this disclosure, further, for example as shown in the figures, each temperature sensing assembly 12 also includes a thermally conductive intermediate 120 arranged to contact a corresponding connector (e.g., threaded member 113), into which the temperature sensor 121 is inserted. Correspondingly, as an example, the guide 122 is mounted above the top of the intermediate 120 and at least partially covers the intermediate 120 and the temperature sensor 121. This provides additional support for the temperature sensor 121 using the intermediate 120, facilitating reliable holding and secure positioning of the temperature sensor 121 and correspondingly the guide 122 relative to the threaded member 113.

[0067] Furthermore, regarding the guide 122, in a specific embodiment, as shown in the figure as an example, the at least one guide 122 at least partially covers the top of the intermediate member 120, and the guide 122 has at least one intermediate hole to allow the pin 1212 of the temperature sensor 121 to be led out from the intermediate member 120 axially away from the threaded member 113.

[0068] In a more specific exemplary embodiment, the temperature sensor 121 further includes a temperature sensing component 1211 configured to sense the temperature at its location and to establish a heat transfer path between the temperature sensing component 1211 and the connector (e.g., threaded member 113); and the temperature sensor 121 is configured to generate an electrical signal based on the temperature sensed by the temperature sensing component 1211 and to output the electrical signal via the at least one pin 1212.

[0069] In a specific exemplary embodiment, as shown in the figure, the temperature sensing component 1211 is arranged to be surrounded by the intermediate member 120 and pressed against the top of the corresponding connector in a heat-transferring contact. Optionally, the temperature sensing component 1211 may also be arranged to contact (e.g., press against) other portions of the corresponding connector, including the sides.

[0070] With this configuration, based on the direct thermal contact between the temperature sensor 121 and the threaded part 113, the length of the heat transfer path from the threaded part to the temperature sensing component 1211 of the temperature sensor 121 is minimized. As a result, the lag in temperature measurement results caused by heat transfer during temperature sensing and the heat loss caused by the redundant length of the heat transfer path are also minimized.

[0071] According to an exemplary embodiment of this disclosure, further, for example as shown in the figure, the at least one terminal body 111 includes two terminal bodies 111, each having an opposing cylindrical plug-in end 1111 and a flat connecting end 1112, the cylindrical plug-in end 1111 being configured to mate with a corresponding mating terminal of a power distribution connector. As an example, the opposing plug-in end 1111 and connecting end 1112 of the terminal body 111 are, for example, both made of a conductive material such as a metal material, the connecting end 1112 being disposed adjacent to the electrical contact end 1121 of the busbar 112, and the plug-in end 1111 being disposed opposite to the electrical contact end 1121 of the busbar 112. In a more specific embodiment, for example, the plug end 1111 is configured to have a cylindrical wall defining a plug hole, which is configured for insertion by a connection terminal (not shown, such as a mating terminal for a charging gun, for example in the form of a pin) of a corresponding pair of power distribution connector assemblies to establish an electrical connection between the connection terminal and the cylindrical wall or conductive element therein of the plug end via conductive contact. Furthermore, for example, the plug hole includes an inclined locking tab, and the connection terminal of the corresponding pair of power distribution connector assemblies includes a corresponding circumferentially disposed locking groove, the locking tab being configured to abut against the locking groove to prevent the connection terminal from falling off. And, in a more specific embodiment, for example, the connection end 1112 is a sheet-like conductive element and is configured to abut against, for example, an electrical contact end of the busbar via the fastening action of the threaded element (e.g., crimping) or alternatively by welding, to establish an electrical connection between the two via conductive contact. Furthermore, the plug-in end 1111 and the connection end 1112 establish a conductive path between them through the terminal body 111. The bus 112 includes: two conductive cores 1120 respectively electrically connected to the respective connection ends 1112 of the two terminal bodies 111, each conductive core 1120 being made of, for example, a conductive material such as a metal material and having an electrical contact end 1121 extending toward the corresponding terminal body 111; and an insulating portion 1122, including a first insulating section 1122A inserted between the two conductive cores and a second insulating section 1122B wrapped around the two conductive cores 1120.

[0072] Furthermore, in exemplary embodiments according to this disclosure, for example, in response to the connection end 1112 and the corresponding electrical contact end 1121 abutting against each other, the at least one connector includes at least one threaded member 113 extending through and screwed between the connection end of the corresponding electrical contact end and the corresponding terminal body, the at least one threaded member 113 including two threaded members 113, each threaded member 113 extending through and pressing against the connection end 1112 of the electrical contact end 1121 of the corresponding conductive core 1120 and the connection end 1112 of the corresponding terminal body 111 to establish a conductive connection therebetween.

[0073] In a further exemplary embodiment, as an example, the temperature sensing component 1211 is arranged to be surrounded by the intermediate member 120 and pressed against the top of the corresponding connector (e.g., threaded member 113 or fastening pin) in a heat-transferring contact. This minimizes the heat transfer path from the threaded portion where the highest temperature rise occurs to the temperature sensor 121 via the direct contact between the temperature sensing component 1211 and the threaded member 113, thereby improving the accuracy of temperature detection at the highest temperature location of the electrical connection structure 11.

[0074] Thus, through the above configuration, the temperature sensor 121 directly attached to the threaded part 113 enables real-time and accurate temperature detection at the threaded connection in the conventional configuration of the busbar 112 connected to the two terminal bodies 111, reducing measurement errors unnecessarily introduced due to redundant heat conduction paths, and avoiding the need for additional lead frames or printed circuit boards.

[0075] Furthermore, in alternative exemplary embodiments according to this disclosure, for example, in response to the connection end 1112 and the corresponding electrical contact end 1121 being directly fixed together, the at least one connector includes at least one conductive contact that is respectively fixed to both the connection end and the corresponding electrical contact end and the corresponding terminal body. Specifically, as an example, the connection end 1112 and the corresponding electrical contact end 1121 are welded to each other or crimped to mate with each other. In a more specific exemplary embodiment, for example, the at least one conductive contact includes a fastening pin. Thus, substantially, the at least one connector can also be a fastener of other forms than the threaded fasteners mentioned above, as long as it can establish a conductive connection between the connection end 1112 and the corresponding electrical contact end 1121 through contact.

[0076] In a further embodiment of the electrical connection structure 11, as shown in the figure as an example, the intermediate member 120 presses against and substantially covers the upper exposed portion of the corresponding connector (e.g., the top of the threaded part 113 or the top of the fastening pin), excluding the portion covered by the temperature sensing element 1211. This facilitates more adequate heat transfer from the threaded portion where the highest temperature rise occurs to the temperature sensor 121, thereby improving the accuracy of temperature detection at the highest temperature location of the electrical connection structure 11.

[0077] As an example, the temperature sensor 121 is centrally located inside the intermediate member 120, preferably coaxially arranged with the intermediate member 120. Since the top of the threaded part 113 at the screw connection is usually protruding, this arrangement facilitates the temperature sensing component 1211 of the temperature sensor 121 to press against the top of the threaded part 113 as fully as possible to achieve sufficient heat transfer.

[0078] As shown in the figure, as an example, each terminal body 111 extends along the longitudinal direction and has a cylindrical plug end 1111 and a flat connecting end 1112 that are opposite each other along the longitudinal direction.

[0079] Figure 3 The figure is a schematic perspective view of a corresponding electrical connection structure 11 in an alternative electrical connector assembly 10 according to an alternative embodiment of the present disclosure.

[0080] In alternative exemplary embodiments, for example, Figure 3 As shown, each terminal body 111 extends vertically perpendicular to the longitudinal direction and has a cylindrical plug end 1111 and a flat connecting end 1112 that are vertically opposite each other. The connecting end 1112 is arranged to extend vertically to at least partially overlap and contact the electrical contact end 1121 of the corresponding conductive core 1120.

[0081] Thus, a corresponding electrical connection structure 11 is realized for an alternative construction electrical connector assembly 10, which includes terminal bodies 111 extending perpendicularly to each other on busbars 112, and the temperature sensing assembly 12 of this application is also applicable to such an electrical connection structure 11.

[0082] In a further exemplary embodiment, for example as shown in the figure, the two conductive cores 1120 of the bus 112 are each plate-shaped and stacked in a vertical direction perpendicular to the longitudinal direction and spaced apart by the first insulating segment 1122A, and the corresponding electrical contact ends 1121 of the two conductive cores 1120 are offset from each other in a lateral direction perpendicular to both the longitudinal and vertical directions. In other words, in the illustrated embodiment, the width of each electrical contact 1121 of the bus 112 is smaller than the width of the portion of the bus 112 excluding the electrical contact 1121, and the electrical contact 1121 of the bus 112 includes two electrical contact 1121 offset relative to each other along the width direction of the bus, one having the same thickness as the overall thickness of the bus and electrically connected to the upper (i.e., the side facing the connector) conductive core, and the other having a thickness smaller than the overall thickness of the bus, i.e., it is recessed, specifically, for example by material removal, and electrically connected to the lower (i.e., the side opposite the connector) conductive core. That is, the two conductive cores 1120 partially overlap each other in the vertical, i.e., thickness direction and are electrically connected to the respective electrical contact 1120. As an example, the vertical projections of a pair of flat conductive cores 1120 at least partially overlap each other.

[0083] In this arrangement, the two conductive cores are stacked vertically, at least partially along the thickness direction of the busbar, and their respective electrical contact ends are staggered from each other along the width direction of the busbar. Compared with the prior art, two pairs of electrical connections from the two conductive cores to their respective different connection ends are achieved on a limited projected area. This can effectively improve space utilization and increase the actual usable conductive width of the flat conductive core 1120, thereby improving the current carrying capacity of the conductive core 1120.

[0084] Furthermore, by having the electrical contact ends 1121 of the two stacked flat conductive cores 1120 staggered laterally, it is convenient to improve space utilization and realize the screwing connection with the connection ends 1112 of the corresponding terminal bodies 111. That is, the two screwing parts are actually arranged side by side in the lateral direction, thereby avoiding unnecessary length extension caused by arranging the screwing parts in the longitudinal direction.

[0085] In an exemplary embodiment according to this disclosure, as shown, for example, the electrical contact end 1121 of each conductive core 1120 and the connection end 1112 of the corresponding terminal body 111 are stacked vertically in a direction perpendicular to the longitudinal direction. Since both the electrical contact end 1121 and the corresponding connection end 1112 are flat, this vertical stacking facilitates sufficient contact and a firm connection between them, thereby ensuring a reliable electrical connection.

[0086] In a further embodiment, for example as shown in the figure, the electrical contact end 1121 of each conductive core 1120 is located vertically above the connection end 1112 of the corresponding terminal body 111. Thus, each electrical contact end 1121 is held between the threaded member 113 and the corresponding connection end 1112.

[0087] Furthermore, regarding the screw connection between the busbar 112 and the terminal body 111, in a more specific embodiment, for example as shown in the figure, a first through hole 1121 is formed for the corresponding electrical contact end 1121 of each conductive core 1120, and a second through hole 11120 is formed for the connection end 1112 of the corresponding terminal body 111 of each conductive core 1120. Based on the arrangement of the electrical contact end 1121 as discussed above the corresponding connection end 1112 in the vertical direction, the corresponding thread 113 of each conductive core 1120 extends sequentially through the first hole 11210 and the second hole 11120.

[0088] Figure 5 A schematic perspective view of two electrical connector cylinders 11201 is shown.

[0089] In an exemplary embodiment according to this disclosure, as shown, for example, each conductive core 1120 further includes an electrical connecting cylinder 11201, the electrical connecting cylinder 11201 comprising: a hollow conductive cylinder portion 11201A, the cylindrical outer surface of the conductive cylinder portion 11201A being adapted to be received in the first hole 11210 of the electrical contact end 1121 of the conductive core 1120; and a peripheral flange 11201B extending circumferentially outward from the outer surface of the conductive cylinder portion 11201A, thereby such that the electrical connecting cylinder 11201 is supported to the corresponding conductive core 1120. As an embodiment, the conductive cylinder portion 11201A is riveted to the corresponding first hole 11210 and is not covered by insulating material, thus being exposed from the insulating portion 1122 of the busbar 112 for contact conductivity.

[0090] In the illustrated embodiment, the raised top surfaces of the two electrical connecting cylinders 11201 are flush with each other in the same plane perpendicular to the vertical.

[0091] In an exemplary embodiment according to the present disclosure, for example as shown in the figure, the interior of the conductive cylindrical portion 11201A is defined with a through hole extending vertically through the portion and having an elliptical cross-section, the minor axis dimension of which is adapted to receive a corresponding threaded member 113.

[0092] In an exemplary embodiment according to the present disclosure, for example as shown in the figure, the elliptical cross-section of the through hole of the conductive cylindrical portion 11201A is arranged with its long axis parallel to the longitudinal direction.

[0093] This arrangement provides longitudinal mounting redundancy when each terminal body 111 is screwed to the busbar 112, enabling the two terminal bodies 111 to be arranged substantially side-by-side.

[0094] In exemplary embodiments according to this disclosure, for example, the terminal body 111 and the electrical connector 11201 are made of copper to improve their conductivity. The flat conductive core 1120 is made of aluminum as an aluminum busbar to reduce manufacturing costs while still ensuring conductivity.

[0095] Although not illustrated, in exemplary embodiments of this disclosure, for example, the conductive cylindrical portion 11201A of the aforementioned electrical connecting cylinder 11201 may be integrally formed within the first hole 11210.

[0096] In an exemplary embodiment according to this disclosure, as shown, for example, the electrical connecting sleeves 11201 of the two conductive cores 1120 extend beyond the lower surface of the respective conductive core 1120 by different lengths, and the difference between these two lengths is substantially equal to the vertical distance L between the lower surfaces of the two conductive cores 1120. This arrangement ensures that the two different electrical connecting sleeves 11201 are flush at their respective lower ends in the vertical direction, facilitating the coplanar pressing of the upper surfaces of the connecting ends 1112 of the two terminal bodies 111 against and subsequently screwed to the lower surfaces of the two electrical connecting sleeves 11201.

[0097] In an exemplary embodiment according to the present disclosure, as shown for example, the upper part of the first hole 11210 has a recessed first flared opening 11210A, which is configured to at least partially receive and constrain the nut of the corresponding threaded member 113. The lower part of the first hole 11210 has a recessed second flared opening 11210B, which is configured to at least partially receive and constrain the peripheral flange 11201B of the corresponding electrical connector 11201. The second hole 11120 is a through hole in the form of a smooth hole with a single inner diameter for the free end of the threaded member 113 to extend through and protrude.

[0098] Figure 6 A schematic perspective view of nut 114 is shown. Correspondingly, as an example, as shown, the electrical connection structure 11 also includes two nuts 114, each nut 114 being screwed to engage the external thread of the corresponding threaded member 113 extending from the second hole 11120 with its internal thread to press the corresponding electrical contact end 1121 and the corresponding connection end 1112 between the nut and the nut 114. With this arrangement, taking into account that the electrical contact end 1121 of each conductive core 1120 discussed above the connection end 1112 of the corresponding terminal body 111 in the vertical direction, the screwing of the nut 114 at the bottom securely and reliably clamps and screws the upper electrical contact end 1121 and the lower corresponding connection end 1112 located therebetween using the threaded member 113 and the nut 114.

[0099] In an exemplary embodiment according to this disclosure, the intermediate member 120 is a seal made of a thermally conductive material, illustrated as a sealing ring. Furthermore, as a further example, the intermediate member 120 is a sealing ring made of silicone with high thermal conductivity. This utilizes the high thermal conductivity of the thermally conductive silicone to achieve sufficient heat transfer between the threaded member 113 and the temperature sensing element 1211 of the temperature sensor 121.

[0100] Based on the above-described configuration, the electrical connector assembly 10 achieves direct heat transfer from the threaded member 113 to the temperature sensing component 1211 by directly abutting the top of the threaded member 113 at the threaded portion with the highest temperature rise (fully contacting the top slot). Simultaneously, a sealing ring made of thermally conductive silicone with high thermal conductivity surrounds the temperature sensing component 1211, and this sealing ring also fully covers the remaining exposed portion of the top of the threaded member 113 not contacted by the temperature sensing component 1211. This allows for additional heat transfer from the remaining exposed portion of the top of the threaded member 113 to the surrounded temperature sensing component 1211 via the thermally conductive sealing ring, thus achieving auxiliary heat transfer. Therefore, the heat from the threaded member 113 is sufficiently conducted to the temperature sensing component 1211 until or near thermal equilibrium is achieved, facilitating improved temperature measurement accuracy and reducing heat loss and temperature measurement errors caused by additional installation structures and heat transfer components. Furthermore, it enables convenient two-step assembly.

[0101] Figure 7A The figure shows a schematic perspective view of a charging stand according to an embodiment of the present disclosure. Figure 7B and Figure 7C The figures illustrate a schematic exploded view of the charging dock completely exploded according to an embodiment of the present disclosure, and a schematic exploded view of it partially split apart (where the electrical connector assembly is fully shown).

[0102] According to the second aspect of this disclosure, such as Figure 7A and Figure 7B The present disclosure also provides a charging dock 1, preferably a charging dock for an electric vehicle, comprising: the aforementioned electrical connector assembly 10; and a housing 20, the housing 20 comprising: a housing body 200 configured to at least partially accommodate the electrical connector assembly 10.

[0103] In an exemplary embodiment according to the present disclosure, for example as shown, the housing 20 further includes: a snout 201 configured to project longitudinally from the housing body 200 and configured to at least partially constrain the longitudinally extending portion of the manifold 112 beyond the housing body 200 in the circumferential direction; at least one externally open hollow compartment 202, each compartment 202 extending vertically from the top of the housing body 200 in a direction perpendicular to the longitudinal direction and configured for insertion of the corresponding connector, such as the threaded member 113.

[0104] In an exemplary embodiment according to the present disclosure, for example as shown, each connector is configured to be positioned between the at least one terminal body 111 and the busbar in response to the insertion and installation of the at least one terminal body 111 and the busbar within the housing 20, and a portion of each connector is housed within the housing body 200 and another portion extends from the housing body 200 into a corresponding compartment 202.

[0105] In an exemplary embodiment according to the present disclosure, for example as shown, the temperature sensor in the corresponding temperature sensing assembly 12 is configured to be installed in the corresponding compartment 202 of the housing 20 in thermal contact with the connector in response to the connector being connected between the at least one terminal body 111 and the busbar, and the temperature sensor abuts against the connector, preferably against the top of the connector.

[0106] As an example, as shown in the figure, the outer surface of each compartment 202 is provided with a pair of lugs 2020 facing each other in the circumferential direction, and correspondingly, the outer surface of the corresponding guide 122 is formed with a pair of recesses 1225 facing each other in the diametrical direction. Each lug 2020 and the corresponding recess are configured to be assembled in response to the temperature sensor being installed in the corresponding compartment 202 of the housing 20 and in thermal contact with the connector to snap together so as to removably attach the corresponding guide 122 to each compartment 202.

[0107] In an exemplary embodiment according to the present disclosure, for example as shown, the guide 122 is configured to be installed into a corresponding compartment 202 of the housing 20 in response to each of its recesses being assembled with a corresponding lug 2020 to engage with each other, and the guide 122 covers the externally open openings of the temperature sensing assembly 12 and the compartment 202.

[0108] In an exemplary embodiment according to the present disclosure, for example as shown, the at least one pin 1212 of the temperature sensor is configured to be moved by the slot of the guide 122 to be constrained by the central hole 1220 in response to the guide 122 being mounted to a corresponding compartment 202 of the housing 20.

[0109] In an exemplary embodiment according to this disclosure, as shown, for example, each pin 1212 of the temperature sensor is configured to be partially bent in response to being guided by the slot to be constrained by the central hole 1220, and the portion of the pin 1212 exposed to the outside from the central hole 1220 is at least partially rotated relative to the unbent portion of the pin 1212 to the lead-out direction. As a further example, the portion of the pin 1212 exposed to the outside from the central hole 1220 is constrained to the lead-out direction. For example, more specifically, a second portion 1212B of the pin is forceped at the central hole 1220 of the corresponding guide 122 and bent at an angle (e.g., 90 degrees) relative to the first portion 1212A of the pin and further extends into the gap 1224 defined between the corresponding two ribs 1223. Furthermore, for example, in response to the second portion 1212B of the pin being angled relative to the first portion 1212A into the gap 1224 defined between the respective two ribs of the guide, the second portion 1212B is further held in the gap 1224 due to the free ends of the two ribs protruding toward each other, thereby constraining the portion of the pin 1212 exposed to the outside from the central hole 1220 to the lead-out direction.

[0110] In a further exemplary embodiment according to this disclosure, as shown in the figure, for example, a spacer 2001 located at the radial center is formed inside the housing body 200. The spacer 2001 divides the interior of the housing 20 into a first chamber 2001A facing the busbar 112 and a second chamber 2001B facing away from the busbar 112. The first chamber 2001A is configured to accommodate at least a portion of the busbar 112 and the connection end 1112 of the at least one terminal body 111. The second chamber 2001B is configured to accommodate the insertion end 1111 of the at least one terminal body 111. The spacer 2001 facilitates fixing the insertion end to reliably receive the inserted mating terminal and achieves physical isolation between the space accommodating the mating terminal and the screw space, avoiding material intrusion and the effects of electrical and thermal conductivity.

[0111] In an exemplary embodiment according to this disclosure, as shown, for example, the electrical contact 1121 of the bus 112 is housed within the first chamber 2001A inside the housing body 200, and the portion of the bus 112 other than the electrical contact 1121 is at least partially housed within the snout 201. Thus, the bus is securely positioned within the housing body and the snout.

[0112] In an exemplary embodiment according to this disclosure, as shown, for example, the at least one connector passes through the corresponding compartment 202 and is inserted into the first chamber 2001A inside the housing body 200. Correspondingly, the corresponding intermediate member 120 passes at least partially through the corresponding compartment 202 and is inserted into the first chamber 2001A inside the housing body 200. Thus, the connector (e.g., threaded member 113) and the corresponding intermediate member 120 are positioned through the housing body and the corresponding compartment.

[0113] In a further exemplary embodiment according to this disclosure, as shown, for example, the charging base 1 further includes: a pad 203, fitted onto the busbar 112 and filling the space between the housing body 200 and the busbar 112, and abutting against the side of the spacer 2001 opposite to the second chamber 2001B; and a plug 204, fitted onto the busbar 112 and housed within the snout 201, located longitudinally outside the pad 203, and configured to push the pad 203 toward the spacer 2001. This achieves a complete seal of the interior, preventing dust, foreign matter, or moisture from intruding into the conductive structure and heat transfer path, thus avoiding adverse effects on conductivity, heat transfer, and temperature sensing.

[0114] Furthermore, considering that the charging dock 1 provided in the second aspect of this disclosure includes the aforementioned electrical connector assembly 10, it also possesses the advantages of the aforementioned electrical connector assembly 10, which will not be elaborated here.

[0115] The electrical connector assembly 10 and charging base 1 in the foregoing embodiments of this disclosure can be used to charge electric vehicles or other electric devices. The above description is intended to be illustrative and not restrictive. Although this disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to exemplify preferred embodiments of this disclosure and should not be construed as limiting the disclosure.

[0117] It should be noted that the word "comprising" does not exclude other elements or steps, and the words "a" or "an" do not exclude multiple. Furthermore, any element reference numerals in the claims should not be construed as limiting the scope of this disclosure.
