Description

Technical Field

[0001] This invention belongs to the field of electrical connectors, and in particular relates to a charging socket and charging components for new energy vehicles. Background Technology

[0002] New energy vehicles can be charged using either direct current (DC) or alternating current (AC), corresponding to fast charging and slow charging respectively. Generally, the charging sockets for new energy vehicles have separate DC and AC interfaces, with the DC interface connected to a large-diameter DC wire and the AC interface to a small-diameter AC wire, respectively.

[0003] Some charging sockets have a hybrid AC / DC interface, such as the NACS interface, which can accept both two-phase AC and DC power. The vehicle's control and detection unit can detect the type of current connected. If the current is DC, the battery is charged directly; if the current is AC, the onboard charger converts the AC to DC before charging the battery.

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

[0005] Heat is generated at the connection points between the contacts and wires in a charging socket. To monitor the temperature at these points in real time, a temperature sensor is often installed inside the charging socket. For example, Chinese invention patent application CN115060392A, published on September 16, 2022, discloses a temperature measuring structure for the power terminals of a vehicle charging socket. This temperature measuring structure includes a heat-conducting element for connection with the contacts, a heat-conducting insulating pad on the heat-conducting element, and a temperature sensing element on the heat-conducting insulating pad. The contacts are directly connected to the wires by a crimping method.

[0006] When both DC and AC wires need to be connected to the AC / DC integrated interface, the DC and AC wires must first be connected to wire terminals at their ends, and then the wire terminals are connected to the contacts. The wire terminals connected to the DC wires are DC terminals, and the wire terminals connected to the AC wires are AC terminals. In this case, directly measuring the temperature of the contacts as described in the aforementioned patent application cannot accurately obtain the temperature values ​​at the DC and AC terminals. It is necessary to equip both the DC and AC terminals with heat-conducting elements, heat-conducting insulating pads, and temperature sensing elements. This results in a significant increase in the internal space of the charging socket, making it difficult to control the size of the charging socket. Furthermore, the large number of temperature sensing elements and leads contributes to the complexity of the charging socket's structure and the cumbersome assembly process. Summary of the Invention

[0007] One of the objectives of this invention is to provide a charging socket for new energy vehicles, which solves the technical problems of existing technologies where connecting both DC and AC wires to an AC / DC integrated interface requires configuring each terminal with a heat-conducting element, a heat-conducting insulating pad, and a temperature sensing element, resulting in excessive internal space occupation, hindering miniaturization of the charging socket, and causing complex structure and inconvenience in assembly.

[0008] Another objective of this invention is to provide a charging component for new energy vehicles to solve the aforementioned technical problems.

[0009] To achieve the above objectives, the technical solution for the new energy vehicle charging socket provided by this invention is as follows:

[0010] A new energy vehicle charging socket includes a contact element, which includes a plug-in portion and a connecting portion. The connecting portion is used to connect an AC terminal and a DC terminal. The new energy vehicle charging socket also includes a conductive and thermally conductive component for conductive and thermally conductive connection with both the AC terminal and the DC terminal, and a temperature detection element for measuring the temperature of the conductive and thermally conductive component. The new energy vehicle charging socket is also provided with a fixed connection structure for fixing and installing the temperature detection element.

[0011] As a further improvement, the conductive and thermally conductive component is thermally connected to a thermally conductive insulating component, and the temperature sensing element is thermally connected to the thermally conductive insulating component, with the thermally conductive insulating component constituting the aforementioned fixed connection structure.

[0012] As a further improvement, the thermally conductive insulating component is provided with a perforation, and the conductive and thermally conductive component is located inside the perforation and is interference-fitted with the inner wall of the perforation.

[0013] As a further improvement, the conductive and thermally conductive components are designed to be electrically and thermally connected to the AC and DC terminals respectively, with both ends protruding from the thermally conductive insulating component.

[0014] As a further improvement, the new energy vehicle charging socket includes a mounting bracket, on which a temperature detection element is fixedly mounted. The temperature detection element is in direct contact with the conductive and heat-conducting component or there is a gap between the temperature detection element and the conductive and heat-conducting component. The mounting bracket is configured as the fixed connection structure described above.

[0015] As a further improvement, the two ends of the conductive and heat-conducting component are respectively used to abut against the DC terminal and the AC terminal. The new energy vehicle charging socket also includes fasteners for pressing the DC terminal and the AC terminal against the two ends of the conductive and heat-conducting component.

[0016] As a further improvement, the conductive and heat-conducting component has a through-hole, through which fasteners pass during use, as well as through-holes on the AC and DC terminals.

[0017] As a further improvement, the fastener is a connecting bolt used to thread through the through holes on the AC and DC terminals and the center hole of the conductive and heat-conducting ring to the connection part of the contact.

[0018] As a further improvement, the thermally conductive insulation component is provided with mounting holes, into which temperature sensing elements are inserted.

[0019] As a further improvement, the thermally conductive insulating component has an annular portion and a protrusion located on one side of the annular portion. The conductive and thermally conductive component is mounted on the annular portion, and a mounting hole is provided on the protrusion, into which a temperature sensing element is inserted.

[0020] As a further improvement, a protective shell is fixed to the outer side wall of the thermally conductive insulating component, except for the plane wall where the two end holes of the perforation are located.

[0021] The beneficial effects are as follows: The new energy vehicle charging socket provided by this invention belongs to the category of inventions that change the relationship between elements in an invention involving changes in elements. This invention utilizes a temperature detection element to monitor the temperature of both the AC and DC terminals, which reduces the number of parts in the new energy vehicle charging socket compared to existing technologies, thus facilitating its miniaturization. Furthermore, due to the smaller number of temperature detection elements, fewer lead wires are required, resulting in a simpler structure and easier assembly of the new energy vehicle charging socket.

[0044] The present invention will be further described in detail below with reference to the embodiments.

[0045] To address the problems in the prior art, the present invention is designed to make the conductive and heat-conducting components electrically and thermally connected to both the AC and DC terminals, thereby utilizing a single temperature sensing element to monitor the temperature of the AC and DC terminals, reducing the number of parts and simplifying the structure.

[0046] Specific embodiment 1 of the new energy vehicle charging component provided by the present invention:

[0047] A charging component for new energy vehicles, see attached. Figure 1 It includes 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 a DC terminal 3 by welding, and the end of the AC wire 6 is fixedly connected to an AC terminal 4 by crimping.

[0048] See attached Figure 1The new energy vehicle charging socket includes a housing 1, and a contact 2 is installed inside the housing 1. 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 into and cooperate 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.

[0049] See appendix Figure 1 and attached Figure 2 Both the AC terminal 4 and the DC terminal 3 are located on the same side of the connecting part 22. The DC terminal 3 is in direct contact with the connecting part 22, while the AC terminal 4 is located on the side of the DC terminal 3 away from the contact member 2. A conductive and heat-conducting member 7 is also provided between the AC terminal 4 and the DC terminal 3. The two ends of the conductive and heat-conducting member 7 are respectively an AC contact end and a DC contact end that abut against the AC terminal 4 and the DC terminal 3 to form conductive contact. In this embodiment, the conductive and heat-conducting member 7 is a ring with a through-hole, and the AC contact end and the DC contact end are located at opposite axial ends of the conductive and heat-conducting member 7. In other embodiments, the conductive and heat-conducting member 7 can also be a rectangular column with a rectangular center hole. The cross-sectional shape of the conductive and heat-conducting member 7 can also be triangular or hexagonal, which will not be elaborated here.

[0050] The new energy vehicle charging socket also includes a connector, specifically a connecting bolt 8. Both the AC terminal 4 and the DC terminal 3 have through holes, while the connecting portion 22 of the contact 2 has a threaded hole 9. During assembly, the connecting bolt 8 passes sequentially through the through hole on the AC terminal 4, the center hole of the conductive and heat-conducting component 7, and the through hole on the DC terminal 3, finally connecting to the threaded hole 9 on the contact 2. Tightening the connecting bolt 8 presses the AC terminal 4 and the DC terminal 3 onto the AC and DC contact ends of the conductive and heat-conducting component 7, respectively, thus maintaining a good electrical connection between the AC terminal 4 and the DC terminal 3 and the conductive and heat-conducting component 7. Furthermore, the connecting bolt 8 can also press the DC terminal 3 onto the connecting portion 22 of the contact 2, maintaining a good electrical connection between the DC terminal 3 and the contact 2.

[0051] The new energy vehicle charging socket also includes a thermally conductive insulating component 10, see appendix. Figure 3 and attached Figure 4The thermally conductive insulating component 10 includes an annular portion 101 and a protrusion 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 its axial direction, forming a through hole. A conductive and thermally conductive component 7 is installed in the through hole, and the outer peripheral surface of the conductive and thermally conductive component 7 is interference-fitted with the inner wall of the through hole. A mounting hole 11 is provided on the protrusion 102. The depth direction of the mounting hole 11 is perpendicular to the axial direction of the through hole, and a temperature sensing element 12 is inserted into the mounting hole 11. The temperature sensing element 12 can be a thermocouple, a resistance temperature detector (RTD), a thermistor, etc. The temperature sensing element 12 is prior art and will not be described in detail here. Since the temperature sensing element 12 is fixedly mounted on the conductive and thermally conductive component 7 through the thermally conductive insulating component 10, the thermally conductive insulating component 10 constitutes a fixed connection structure.

[0052] Inserting the temperature sensing element 12 into the mounting hole 11 allows for a larger contact area between the temperature sensing element 12 and the thermally conductive insulating component 10, improving the accuracy of the detection. Furthermore, providing a protrusion 102 on the thermally conductive insulating component 10 and placing the mounting hole 11 on the protrusion 102 allows for a smaller overall size of the thermally conductive insulating component 10 while ensuring sufficient depth of the mounting hole 11.

[0053] The dimension of the thermally conductive insulating component 10 in the axial direction of the perforation is smaller than the axial dimension of the conductive and thermally conductive component 7. Furthermore, during assembly, both the AC and DC contact ends of the conductive and thermally conductive component 7 protrude from the thermally conductive insulating component 10, thus leaving gaps between the thermally conductive insulating component 10 and the AC terminal 4 and DC terminal 3. This ensures effective contact and compression between the conductive and thermally conductive component 7 and the DC terminal 3 and AC terminal 4, guaranteeing good electrical and thermal conductivity.

[0054] A protective shell 13 is provided on the outside of the thermally conductive insulating component 10. The protective shell 13 can be used to protect the thermally conductive insulator and prevent the thermally conductive insulating component 10 from deformation and damage during assembly.

[0055] The conductive and heat-conducting component 7 serves to conduct electricity and heat between the AC terminal 4 and the DC terminal 3. Therefore, regardless of whether the AC terminal 4 or the DC terminal 3 is heating up, the heat can be conducted to the conductive and heat-conducting component 7, and then the heat is transferred from the conductive and heat-conducting component 7 to the heat-conducting insulating component 10. Since only one of the AC terminal 4 and the DC terminal 3 has current flowing through it at any given time, the type of current flowing through it can be used to determine which of the AC terminal 4 and the DC terminal 3 is heating up. At this time, the temperature value obtained by the temperature sensing element 12 is the temperature value of the component in the heating state between the AC terminal 4 and the DC terminal 3.

[0056] Because the conductive and heat-conducting element 7 is located within the perforation on the thermally conductive and insulating element 10, the contact area between the conductive and heat-conducting element 7 and the thermally conductive and insulating element 10 is relatively large, facilitating rapid heat transfer. Furthermore, the conductive and heat-conducting element 7 is annular, which allows for a larger outer circumferential area with the same amount of material, further improving the heat transfer efficiency between the conductive and heat-conducting element 7 and the thermally conductive and insulating element 10. It also provides space for the connector; by passing the connector through the central hole of the conductive and heat-conducting element 7, the force on the conductive and heat-conducting element 7 can be ensured to be uniform.

[0057] Compared to existing technologies, this new energy vehicle charging socket can use a single temperature sensing element 12 to monitor the temperature of the AC terminal 4 and the DC terminal 3. The number of temperature sensing elements 12 used in this new energy vehicle charging socket is smaller, as are the number of conductive and heat-conducting components 7 and thermally insulating components 10. On the one hand, this reduces space occupation and facilitates the miniaturization of the new energy vehicle charging socket; on the other hand, the reduction in the number of temperature sensing elements 12 also reduces the number of leads, simplifying the structure of the new energy vehicle charging socket and making assembly easier.

[0058] See attached Figure 1 and attached Figure 5 In addition to the DC wire 5 and AC wire 6 used for charging, the new energy vehicle charging socket also includes a signal transmission wire 14 for transmitting signals. The housing 1 has two independent chambers; the signal transmission wire 14 is located in one chamber, and the DC wire 5 and AC wire 6 are located in the other chamber.

[0059] Both chambers have openings at their rear ends for wires to pass through. The chamber containing the DC wire 5 and the AC wire 6 has two openings at its rear end, with a first cover 15 and a second cover 16 installed at the two openings respectively. The chamber containing the signal transmission wire 14 has one opening at its rear end, with a third cover 17 installed at this opening.

[0060] The first cover 15, the second cover 16, and the third cover 17 are all provided with wire-passing holes for corresponding wires to pass through, and sealing elements are provided in the wire-passing holes for sealing. The AC wire 6 passes through the wire-passing hole of the first cover 15, the DC wire 5 passes through the wire-passing hole of the second cover 16, and the signal transmission wire 14 passes through the wire-passing hole of the third cover 17.

[0061] Since the voltage on DC wire 5 and AC wire 6 is higher than that on signal transmission wire 14, separating signal transmission wire 14 from DC wire 5 and AC wire 6 improves safety. During wire harness fabrication, the third cover 17 can be placed on signal transmission wire 14, the second cover 16 on DC wire 5, and the first cover 15 on AC wire 6. These covers do not interfere with each other, greatly simplifying wire harness fabrication compared to sharing a single cover with DC wire 5, AC wire 6, and signal transmission wire.

[0062] In other embodiments, if the thermally conductive insulation is strong enough, a protective shell may not be required.

[0063] In other embodiments, the thermally conductive insulation may only have an annular portion, in which a mounting hole is formed on the annular portion, and the wall thickness of the annular portion may be increased in order to make the mounting hole have sufficient depth.

[0064] In other embodiments, mounting holes may not be provided on the thermally conductive insulating component, and the temperature sensing element may be fixed to the outside of the thermally conductive insulating component by adhesive bonding.

[0065] In the above embodiments, gaps are left between the thermally conductive insulating component and both the AC and DC terminals. This ensures that the thermally conductive insulating component is positioned between the AC and DC contact ends of the conductive and thermally conductive component during assembly, preventing the thermally conductive insulating component from protruding from the conductive and thermally conductive component due to insufficient assembly precision, thus avoiding affecting the effective contact between the conductive and thermally conductive component and the AC and DC terminals. In other embodiments, the axial dimension of the thermally conductive insulating component in the perforation direction can be equal to the axial dimension of the conductive and thermally conductive component. In this embodiment, the thermally conductive insulating component can contact both the AC and DC terminals, thereby increasing the thermally conductive contact area.

[0066] In other embodiments, the connecting bolts may not pass through the central hole of the conductive and heat-conducting component. In this embodiment, two through holes are provided on both the DC terminal and the AC terminal, two threaded holes are provided on the contact component, and two connecting bolts are provided, with the two connecting bolts located on both sides of the outside of the conductive and heat-conducting component.

[0067] In other embodiments, the connector can also be a threaded post fixedly connected to the connecting end of the contact. During assembly, the combination of DC terminal, conductive and heat-conducting component and heat-conducting insulating component, and AC terminal are sequentially strung on the threaded post. Then, a nut is installed on the threaded post. After tightening the nut, the AC terminal and DC terminal can be pressed against the two ends of the conductive and heat-conducting component respectively, and the DC terminal can be pressed against the contact.

[0068] In other embodiments, the connector may not be provided, and the DC terminal may be directly welded to the contact, while the conductive and heat-conducting components may be welded to both the DC terminal and the AC terminal.

[0069] In other embodiments, the DC and AC terminals can be respectively fixed to the contact element using bolts. Specifically, the DC and AC terminals can be fixed side-by-side on the same side of the contact element, or they can be fixed on opposite sides of the contact element. In this type of embodiment, both ends of the conductive and heat-conducting element have connection holes. When installing the DC terminal, the end of the conductive and heat-conducting element with the connection hole is placed between the DC terminal and the contact element, and the bolt for fixing the DC terminal passes through the corresponding connection hole. After tightening the bolt, the conductive and heat-conducting element is pressed between the DC terminal and the contact element. The other end of the conductive and heat-conducting element is pressed between the AC terminal and the contact element in a similar manner. In this type of embodiment, due to space limitations, the thermally conductive insulating element does not need to be sleeved onto the conductive and heat-conducting element, but can be glued and fixed to one side of the conductive and heat-conducting element.

[0070] Specific embodiment 2 of the new energy vehicle charging component provided by the present invention:

[0071] This embodiment is based on Embodiment 1, but differs from Embodiment 1 in that a mounting bracket is used instead of a thermally conductive insulating component in this embodiment.

[0072] See appendix Figure 6 and attached Figure 7 The mounting bracket 18 is a cylindrical structure with open ends. During the assembly of the new energy vehicle charging socket, the mounting bracket 18 needs to be placed on the conductive and heat-conducting component 7. Then, the DC terminal and AC terminal are tightened with connecting bolts. While the DC terminal and AC terminal are pressing the conductive and heat-conducting component, the mounting bracket 18 is also pressed between the two to fix the mounting bracket.

[0073] The mounting bracket 18 has mounting holes 181 for mounting temperature sensing elements, and one end of the mounting bracket 18 has a notch 182 that communicates with the mounting holes 181.

[0074] The head of the temperature sensing element 12 has a metal cover, and the tail end of the cover is provided with an outwardly folded flange to cooperate with the mounting bracket 18 during the installation of the temperature sensing element 12 and limit the direction of installation.

[0075] In this embodiment, the temperature sensing element 12 itself has an insulating layer, so there is no need to set an additional insulating material to separate it from the conductive and heat-conducting component 7.

[0076] The head of the temperature sensing element 12 can directly contact the conductive and heat-conducting component 7, transferring heat through thermal conduction to measure the temperature of the conductive and heat-conducting component 7. In other embodiments, a gap may be left between the head of the temperature sensing element 12 and the conductive and heat-conducting component 7, allowing heat to be transferred through air conduction and thermal radiation to measure the temperature of the conductive and heat-conducting component 7.

[0077] The mounting bracket can be made of metal or non-metallic insulating material. In other embodiments, the mounting bracket can also be directly interference-fitted onto the conductive and heat-conducting component. In this embodiment, the mounting bracket is configured as a fixed connection structure.

[0078] Specific embodiment 3 of the new energy vehicle charging component provided by the present invention:

[0079] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the temperature detection element in this embodiment is fixed to the conductive and heat-conducting component by adhesive tape. Therefore, the adhesive tape in this embodiment constitutes a fixed connection structure.

[0081] The new energy vehicle charging socket is the new energy vehicle charging socket in specific embodiment 1, embodiment 2 or embodiment 3 of the above-mentioned new energy vehicle charging component, and will not be described again.

[0082] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
