Description

Technical Field

[0001] The present invention belongs to the field of electric connectors, and in particular relates to a new energy vehicle charging socket and a new energy vehicle charging assembly. Background Art

[0002] New energy vehicles can be charged using direct current or alternating current, with direct current and alternating current corresponding to fast charging and slow charging respectively. Generally, the charging socket of new energy vehicles separates the DC interface and the AC interface, and the DC interface and the AC interface are connected to the large square DC wire and the small square AC wire respectively.

[0003] Some charging sockets have an AC / DC interface, such as the NACS interface, which can be connected to two-phase AC or DC. The control and detection unit in the car can detect the type of current connected. If the current connected is DC, the battery is charged directly. If the current connected is AC, the on-board charger in the car converts the AC into DC before charging the battery.

[0004] For new energy vehicle manufacturers that originally used charging sockets with separate DC and AC interfaces, if they want to switch to the above-mentioned integrated AC / DC charging socket without changing the wiring layout in the car, they need to connect the large-square DC wire originally connected to the DC interface and the small-square AC wire originally connected to the AC interface to the integrated AC / DC interface.

[0005] The location where the contact in the charging socket is connected to the wire generates a lot of heat. In order to monitor the temperature there in real time, a temperature sensor is often installed in the charging socket. For example, a Chinese invention patent application with application publication number CN115060392A and application publication date September 16, 2022 discloses a temperature measurement structure for a power terminal of a vehicle charging socket, which includes a heat-conducting element connected to the contact, a heat-conducting insulating rubber pad is provided on the heat-conducting element, and a temperature detection element is provided on the heat-conducting insulating rubber pad, wherein the contact is directly connected to the wire by crimping.

[0006] When it is necessary to connect both the DC wire and the AC wire to the integrated AC / DC interface, the DC wire and the AC wire need to be connected to the wire terminals at the ends first, and then the wire terminals are connected to the contact pieces, wherein the wire terminals connected to the DC wire are DC terminals, and the wire terminals connected to the AC wire are AC terminals. At this time, directly measuring the temperature of the contact pieces in the manner of the above-mentioned invention patent application cannot accurately obtain the temperature values ​​at the DC terminals and the AC terminals. It is necessary to configure thermal conductive elements, thermal conductive insulation pads and temperature detection elements for both the DC terminals and the AC terminals, which takes up a lot of space inside the charging socket and makes it difficult to control the size of the charging socket; and the number of temperature detection elements used is large, and the number of leads is large, resulting in a complex structure of the charging socket and cumbersome assembly. Summary of the invention

[0007] One of the purposes of the present invention is to provide a new energy vehicle charging socket to solve the technical problems in the prior art that after both the DC wire and the AC wire are connected to the AC / DC integrated interface, each terminal needs to be provided with a thermal conductive element, a thermal conductive insulating pad and a temperature detection element, which occupies a large amount of internal space of the charging socket and is not conducive to the miniaturization of the charging socket, and the charging socket has a complex structure and is not easy to assemble.

[0035] The present invention is further described in detail below in conjunction with embodiments.

[0036] To solve the problems in the prior art, the structural concept of the present invention is to make the conductive and thermally conductive parts conductively and thermally connected to both the AC terminal and the DC terminal, so as to use a temperature detection element to monitor the temperature of the AC terminal and the DC terminal, reduce the number of parts and simplify the structure.

[0037] Specific embodiment 1 of the new energy vehicle charging assembly provided by the present invention: A new energy vehicle charging component, see attached Figure 1 , including a new energy vehicle charging socket, a DC wire 5 and an AC wire 6, the end of the DC wire 5 is fixedly connected to the DC terminal 3 by welding, and the end of the AC wire 6 is fixedly connected to the AC terminal 4 by crimping.

[0038] See attached Figure 1 The new energy vehicle charging socket includes a shell 1, in which a contact 2 is installed. The front part of the contact 2 is a plug-in part 21, and the rear part of the contact 2 is a connecting part 22. The plug-in part 21 is used to plug and match with the adapter contact 2 in the charging gun, and the connecting part 22 is used to connect the AC terminal 4 and the DC terminal 3.

[0039] See attached Figure 1 and attached Figure 2, the AC terminal 4 and the DC terminal 3 are both located on the same side of the connecting portion 22, the DC terminal 3 is directly in contact with the connecting portion 22, the AC terminal 4 is located on the side of the DC terminal 3 away from the contact member 2, and a conductive heat-conducting member 7 is also provided between the AC terminal 4 and the DC terminal 3, and the two ends of the conductive heat-conducting member 7 are respectively an AC abutting end and a DC abutting end that abut against the AC terminal 4 and the DC terminal 3 to form contact and conduction. In this embodiment, the conductive heat-conducting member 7 is a circular ring with a central hole passing through it, and the AC abutting end and the DC abutting end are respectively located at the two axial ends of the conductive heat-conducting member 7. In other embodiments, the conductive heat-conducting member 7 can also be a rectangular column, whose central hole is also rectangular, and the cross-sectional shape of the conductive heat-conducting member 7 can also be a triangle or a hexagon, which will not be elaborated here.

[0040] The new energy vehicle charging socket also includes a connector, which is specifically a connecting bolt 8. Through holes are provided on the AC terminal 4 and the DC terminal 3, and a threaded hole 9 is provided on the connecting portion 22 of the contact 2. During assembly, the connecting bolt 8 passes through the through hole on the AC terminal 4, the center hole of the conductive and thermal conductive member 7, and the through hole on the DC terminal 3 in sequence, and finally connects with the threaded hole 9 on the contact 2. After tightening the connecting bolt 8, the AC terminal 4 and the DC terminal 3 can be pressed against the AC abutment end and the DC abutment end of the conductive and thermal conductive member 7, respectively, so that the AC terminal 4 and the DC terminal 3 maintain good electrical connection with the conductive and thermal conductive member 7. In addition, the connecting bolt 8 can also press the DC terminal 3 against the connecting portion 22 of the contact 2, so that the DC terminal 3 maintains good electrical connection with the contact 2.

[0041] The new energy vehicle charging socket also includes a heat-conducting insulating member 10, see attached Figure 3 and attached Figure 4 The heat-conducting insulating member 10 includes an annular portion 101 and a protruding portion 102 located on one side of the annular portion 101. The annular portion 101 has an inner hole that penetrates the annular portion 101 along the axial direction of the annular portion 101. The inner hole constitutes a through hole. The conductive heat-conducting member 7 is installed in the through hole. The outer peripheral surface of the conductive heat-conducting member 7 is interference fit with the inner wall of the through hole. A mounting hole 11 is provided on the protruding portion 102. The depth direction of the mounting hole 11 is perpendicular to the axial direction of the through hole. A temperature detection element 12 is inserted into the mounting hole 11. The temperature detection element 12 can be a thermocouple, a thermal resistor, a thermistor, etc. The temperature detection element 12 is a prior art and will not be described in detail here. Since the temperature detection element 12 is fixedly mounted on the conductive heat-conducting member 7 through the heat-conducting insulating member 10, the heat-conducting insulating member 10 constitutes a fixed connection structure.

[0042] Inserting the temperature detection element 12 into the mounting hole 11 can make the temperature detection element 12 have a larger contact area with the heat-conducting insulating member 10, thereby improving the detection accuracy. Protrusions 102 are provided on the heat-conducting insulating member 10, and the mounting hole 11 is provided on the protrusions 102, so that the overall size of the heat-conducting insulating member 10 can be reduced while ensuring that the mounting hole 11 has a sufficient depth dimension.

[0043] The dimension of the heat-conducting insulating member 10 in the axial direction of the perforation is smaller than the axial dimension of the heat-conducting conductive member 7, and during assembly, the AC abutting end and the DC abutting end of the heat-conducting conductive member 7 are both protruded from the heat-conducting insulating member 10, so that there are gaps between the heat-conducting insulating member 10 and the AC terminal 4 and the DC terminal 3. In this way, the heat-conducting conductive member 7 can be effectively contacted and pressed with the DC terminal 3 and the AC terminal 4, thereby ensuring good electrical and thermal conductivity.

[0044] A protective shell 13 is disposed on the outer side of the heat-conducting insulating member 10 , and the protective shell 13 can be used to protect the heat-conducting insulator and prevent the heat-conducting insulating member 10 from deformation and collision damage during assembly.

[0045] The conductive and thermally conductive member 7 can conduct electricity and heat between the AC terminal 4 and the DC terminal 3. Therefore, no matter which of the AC terminal 4 and the DC terminal 3 generates heat, the heat can be transferred to the conductive and thermally conductive member 7, and then the heat is transferred from the conductive and thermally conductive member 7 to the thermally conductive insulating member 10. Since only one of the AC terminal 4 and the DC terminal 3 has current passing through it at the same time, it can be determined which of the AC terminal 4 and the DC terminal 3 is in a heating state according to the type of current connected. At this time, the temperature value obtained by the temperature detection element 12 is the temperature value of the component in the AC terminal 4 and the DC terminal 3 that is in a heating state.

[0046] Since the conductive heat-conducting member 7 is located in the through hole on the heat-conducting insulating member 10, the contact area between the conductive heat-conducting member 7 and the heat-conducting insulating member 10 is large, and heat can be easily and quickly transferred. In addition, the conductive heat-conducting member 7 is annular, which can, on the one hand, make the conductive heat-conducting member 7 have a larger peripheral area under the same material dosage, further improving the heat transfer efficiency between the conductive heat-conducting member 7 and the heat-conducting insulating member 10; on the other hand, it also leaves space for the setting of the connector, and passing the connector through the central hole of the conductive heat-conducting member 7 can ensure that the conductive heat-conducting member 7 is subjected to uniform force.

[0047] Compared with the prior art, the new energy vehicle charging socket can use a temperature detection element 12 to monitor the temperature of the AC terminal 4 and the DC terminal 3. The number of temperature detection elements 12 used in the new energy vehicle charging socket is relatively small, and the number of conductive and thermal conductive parts 7 and thermal conductive insulating parts 10 is also relatively small. On the one hand, it can reduce the space occupied, which is conducive to the miniaturization of the new energy vehicle charging socket; on the other hand, after the number of temperature detection elements 12 is reduced, the lead wires can also be reduced accordingly, which simplifies the structure of the new energy vehicle charging socket and facilitates assembly.

[0048] See attached Figure 1 and attached Figure 5 In addition to the DC wire 5 and AC wire 6 for charging, the new energy vehicle charging socket is also provided with a signal transmission wire 14 for transmitting signals. Two independent chambers are provided in the housing 1, the signal transmission wire 14 is provided in one of the chambers, and the DC wire 5 and AC wire 6 are provided in the other chamber.

[0049] The rear ends of the two chambers are both provided with openings for the wires to pass through. The rear end of the chamber where the DC wire 5 and the AC wire 6 are provided is provided with two openings, and the first cover 15 and the second cover 16 are respectively installed at the two openings. The rear end of the chamber where the signal transmission wire 14 is provided is provided with an opening, and the third cover 17 is installed at the opening.

[0050] The first cover 15, the second cover 16 and the third cover 17 are all provided with threading holes for corresponding wires to pass through, and sealing members are provided in the threading holes for sealing. The AC wire 6 passes through the threading hole of the first cover 15, the DC wire 5 passes through the threading hole of the second cover 16, and the signal transmission wire 14 passes through the threading hole of the third cover 17.

[0051] Since the voltage of the DC conductor 5 and the AC conductor 6 is relatively high, and the voltage of the signal transmission conductor 14 is relatively low, the signal transmission conductor 14 is separated from the DC conductor 5 and the AC conductor 6 to improve safety. In the process of making the wiring harness, the third cover 17 can be put on the signal transmission conductor 14, the second cover 16 can be put on the DC conductor 5, and the first cover 15 can be put on the AC conductor 6. The covers will not interfere with each other, which greatly facilitates the wiring harness making compared to the DC conductor 5, the AC conductor 6 and the signal transmission conductor sharing the same cover.

[0052] In other embodiments, if the heat-conducting insulating member is strong enough, the protective shell may not be provided.

[0053] In other embodiments, the thermally conductive insulating member may only have an annular portion. In this embodiment, the mounting hole is opened on the annular portion. In order to make the mounting hole have sufficient depth, the wall thickness of the annular portion may be thickened.

[0054] In other embodiments, the thermally conductive insulating member may not have a mounting hole, and the temperature detection element may be fixed to the outside of the thermally conductive insulating member by gluing.

[0055] In the above embodiments, gaps are left between the heat-conducting insulating member and the AC terminal and the DC terminal, which can ensure that the heat-conducting insulating member is between the AC abutting end and the DC abutting end of the conductive heat-conducting member during assembly, and prevent the heat-conducting insulating member from protruding from the conductive heat-conducting member due to insufficient assembly precision, thereby avoiding affecting the effective contact between the conductive heat-conducting member and the AC terminal and the DC terminal. In other embodiments, the size of the heat-conducting insulating member in the axial direction of the perforation can also be made equal to the axial size of the conductive heat-conducting member. In this embodiment, the heat-conducting insulating member can contact both the AC terminal and the DC terminal, thereby increasing the heat-conducting contact area.

[0056] In other embodiments, the connecting bolt may not pass through the center hole of the conductive and heat-conducting component. In this embodiment, two through holes are provided on the DC terminal and the AC terminal, two threaded holes are correspondingly provided on the contact member, two connecting bolts are provided, and the two connecting bolts are respectively located on both sides of the outside of the conductive and heat-conducting component.

[0057] In other embodiments, the connector may also be a threaded column fixedly connected to the connection end of the contact piece. During assembly, the DC terminal, the combination of the conductive and thermally conductive part and the thermally conductive insulating part, and the AC terminal are sequentially strung on the threaded column, and then a nut is installed on the threaded column. After tightening the nut, the AC terminal and the DC terminal can be respectively pressed against the two ends of the conductive and thermally conductive part, and the DC terminal can be pressed against the contact piece.

[0058] In other embodiments, the connector may not be provided, and the DC terminal and the contact member may be directly fixed by welding, and the conductive and thermal conductive member may be fixed by welding to both the DC terminal and the AC terminal.

[0059] In other embodiments, the DC terminal and the AC terminal may be fixed to the contact piece with bolts respectively. Specifically, the DC terminal and the AC terminal may be fixed side by side on the same side of the contact piece, or they may be fixed on both sides of the contact piece. In this type of embodiment, connection holes are provided at both ends of the conductive and thermally conductive part. When installing the DC terminal, one end of the conductive and thermally conductive part with the connection hole is placed between the DC terminal and the contact piece, and the bolt for fixing the DC terminal is passed through the corresponding connection hole. After tightening the bolt, the conductive and thermally conductive part is pressed between the DC terminal and the contact piece; the other end of the conductive and thermally conductive part is pressed between the AC terminal and the contact piece in a similar manner. In this type of embodiment, due to the limitation of the installation space, the thermally conductive insulating part may no longer be mounted on the conductive and thermally conductive part, but may be glued and fixed to one side of the conductive and thermally conductive part.

[0060] Specific embodiment 2 of the new energy vehicle charging assembly provided by the present invention: This embodiment is based on the embodiment 1, and is different from the embodiment 1 in that a mounting frame is used in this embodiment to replace the heat-conducting insulating member.

[0061] See attached Figure 6 and attached Figure 7 The mounting frame 18 is a cylindrical structure with both ends open. In the process of assembling the new energy vehicle charging socket, the mounting frame 18 needs to be put on the conductive and heat-conductive member 7, and then the DC terminal and the AC terminal are fastened with connecting bolts. While the DC terminal and the AC terminal are used to press the conductive and heat-conductive member, the mounting frame 18 is also pressed between the two to fix the mounting frame.

[0062] The mounting frame 18 has a mounting hole 181 for mounting the temperature detection element, and one end of the mounting frame 18 has a notch 182 communicating with the mounting hole 181 .

[0063] The temperature detection element 12 has a metal cover at its head, and a flange folded outward is provided at the rear end of the cover to cooperate with the mounting frame 18 to limit the direction of installation during the process of installing the temperature detection element 12.

[0064] In this embodiment, the temperature detection element 12 itself has an insulating layer, so there is no need to provide additional insulating material to separate it from the conductive and thermal conductive member 7 .

[0065] The head of the temperature detection element 12 can directly contact the conductive heat conductive member 7, and transfer heat by heat conduction to measure the temperature of the conductive heat conductive member 7. In other embodiments, a gap can also be left between the head of the temperature detection element 12 and the conductive heat conductive member 7, and heat can be transferred by heat conduction and heat radiation of the air to measure the temperature of the conductive heat conductive member 7.

[0066] The mounting frame can be made of metal material or non-metallic insulating material. In other embodiments, the mounting frame can also be directly interference-fitted on the conductive and thermal conductive member. In this embodiment, the mounting frame constitutes a fixed connection structure.

[0067] Specific embodiment 3 of the new energy vehicle charging assembly provided by the present invention: This embodiment is based on Embodiment 1, and differs from Embodiment 1 in that the temperature detection element in this embodiment is fixed to the conductive and heat-conductive member by adhesive tape, so the adhesive tape in this embodiment constitutes a fixed connection structure.

[0068] Specific embodiments of the new energy vehicle charging socket provided by the present invention: The new energy vehicle charging socket is the new energy vehicle charging socket in the specific embodiment 1, embodiment 2 or embodiment 3 of the above-mentioned new energy vehicle charging component, and will not be repeated here.

[0069] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
