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 dock. Considering that the aluminum busbar screw connection at the insertion terminal of the adapter connector in the charging dock bus is typically the area with the highest internal temperature rise, a simple structural improvement can be made using the existing threaded features that screw the busbar (e.g., aluminum busbar) to the terminal. On one hand, a seal (e.g., a sealing ring) made of a high thermal conductivity material, such as high thermal conductivity silicone, is provided at this aluminum busbar screw connection. The temperature sensing module of the temperature sensor is embedded within the seal, allowing it to directly abut against the threaded part (e.g., the Phillips or hexagonal notch at its top for screwdriver tightening). On the other hand, the tight fit of the sealing ring against the threaded part facilitates the efficient transfer of heat from the threaded part to the temperature sensing module. Through these two effects, a temperature sensing structure is achieved that effectively detects the temperature at the highest temperature rise point within the charging dock. Furthermore, an additional lead frame and / or printed circuit board for mounting the temperature sensor is no longer required, thus simplifying the structure. Subsequently, the cover is snapped onto the top of the seal, thus enabling the quick-release temperature sensing structure of the charging dock to be realized in just two steps.

Figures 4A to 4B The diagrams show schematic 3D views of the busbar from both top and bottom angles.

[0051] 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, the electrical connection structure 11 includes: at least one terminal body 111, for example, the terminal body 111 is a monolithic piece and is configured to extend vertically, for example, along a longitudinal direction (also referred to as its length direction) or perpendicular to the longitudinal direction, and has opposing insertion ends 1111 and connecting ends 1112, the insertion ends 1111 being, for example, cylindrical for receiving insertion of mating terminals of the power distribution connector assembly, the connecting ends 1112 being, for example, flat; and a bus 112 having at least one electrical contact end 112. 1 (as an example, of the opposing plug-in end 1111 and connection end 1112 of the terminal body 111, the connection end 1112 is disposed adjacent to the electrical contact end 1121 of the bus 112, and the plug-in end 1111 is disposed opposite to the electrical contact end 1121 of the bus 112); and at least one connector (as an example, a threaded member 113, which typically has an external thread) is connected to both the respective electrical contact end 1121 and the connection end 1112 of the respective terminal body 111 to establish a conductive connection therebetween. Furthermore, as an example, as shown in the figure, the electrical connector assembly 10 also includes at least one temperature sensing assembly 12. Each temperature sensing assembly 12 includes: a thermally conductive intermediate 120 abutting against a corresponding connector, more specifically, for example, pressing against the top of the threaded member 113 (more specifically, for example, a notch at the top, more specifically, such as a Phillips head or hexagonal head for screwdriver insertion and tightening); and a temperature sensor 121 inserted into the intermediate 120 and including a temperature sensing element 1211, the temperature sensing element 1211 being surrounded by the intermediate 120 and contacting the corresponding connector, and configured to sense the temperature at its location, establishing a heat transfer path between the temperature sensing element 1211 and the connector. In a specific exemplary embodiment, for example, as shown in the figure, the temperature sensing element 1211 is arranged to be surrounded by the intermediate 120 and pressed against the top of the corresponding connector in a thermally conductive contact. Optionally, the temperature sensing element 1211 may also be arranged to contact (e.g., press against) other portions of the corresponding connector, including the sides.

[0052] This configuration allows for a simple structural improvement to the aluminum busbar screw connection at the insertion terminal of the power connector, typically the area with the highest internal temperature rise in the charging dock 1, via the existing threaded component 113 that screws the busbar 112 (e.g., the aluminum busbar) to the terminal. On one hand, a seal (e.g., a sealing ring) made of a highly thermally conductive material, such as highly thermally conductive silicone, is provided at this aluminum busbar screw connection. The temperature sensing module of the temperature sensor 121 is embedded within this seal, allowing it to directly abut against the threaded component 113 (e.g., the Phillips or hexagonal notch at its top for screwdriver tightening). On the other hand, the tight fit of the sealing ring against the threaded component 113 facilitates the efficient transfer of temperature from the threaded component 113 to the temperature sensing module. Thus, through the synergistic effect of these two aspects, a temperature sensing structure enables real-time sensing of the temperature at the highest temperature rise point within the charging dock 1. Furthermore, the additional lead frame and / or printed circuit board for mounting the temperature sensor 121 is no longer required, thus simplifying the structure.

[0053] 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 through 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 has 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 through 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Furthermore, for the temperature sensing component 12, in a specific embodiment, as shown in the figure as an example, the temperature sensor 121 further includes at least one pin 1212, which is arranged to extend from the temperature sensing element 1211 and to the outside of the intermediate member 120 (illustrated as being bent after being extended to extend in a plane orthogonal to the vertical direction), and is configured to output an electrical signal of the temperature sensor 121.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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 has a thickness equal to the overall thickness of the bus and is electrically connected to the upper (i.e., the side facing the connector) conductive core, while the other has a thickness smaller than the overall thickness of the bus, i.e., it is recessed, specifically, for example, by material removal, and is 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 (thickness) direction and are electrically connected to their respective electrical contact 1120. As an example, the vertical projections of a pair of flat conductive cores 1120 at least partially overlap each other.

[0065] 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 along the lateral direction of the busbar. Compared with the prior art, this achieves two pairs of electrical connections that are separate from each other and lead to the corresponding different connection ends of the two conductive cores in 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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, a corresponding connector (e.g., threaded member 113, or fastening pin) for each conductive core 1120 extends sequentially through the first hole 11210 and the second hole 11120.

[0070] Figure 5 A schematic perspective view of two electrical connector cylinders 11201 is shown.

[0071] 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.

[0072] 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.

[0073] 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 connector (e.g., threaded member 113, or fastening pin).

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] In an exemplary embodiment according to this disclosure, as shown, for example, the temperature sensing assembly 12 further includes at least one cover 122 that at least partially covers the top of the intermediate member 120, and the cover 122 has at least one through-hole to allow the pin 1212 of the temperature sensor 121 to be led out axially away from the connector (e.g., threaded member 113, or fastening pin) from the intermediate member 120. With this arrangement, a quick-mount temperature sensing structure for the charging dock 1 can be easily assembled in just two steps by first inserting the temperature sensing element 1211 of the temperature sensor 121 into the sealing ring that serves as the intermediate member 120 until it abuts against the top of the threaded member 113 to be fully enclosed by the thermally conductive sealing ring, and then snapping the cover 122 onto the top of the sealing ring.

[0083] 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.

[0084] 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).

[0085] 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.

[0086] 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 threaded member 113.

[0087] 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 cover 122 is formed with a pair of recesses 1225 facing each other in the diametrical direction. Each lug 2020 and the corresponding recess are snap-fitted together during assembly to removably attach the corresponding cover 122 to each compartment 202.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] According to a third aspect of this disclosure, an electrical connector 1 is also provided, comprising: the aforementioned charging base 1; and a mating connector. The mating connector includes: a mating connector assembly electrically connected to the electrical connector assembly 10; and a mating housing configured to mate with the housing 20, wherein the mating housing defines a recess for insertion and mating of the electrical connector assembly 10 into the mating connector assembly.

[0094] 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.
