DETAILED DESCRIPTION

[0033] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0034] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0035] In the present disclosure, unless otherwise stated, "inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0036] According to a first aspect of the present disclosure, a charging assembly is provided, referring to Figures 1 to 5 As shown, the charging assembly is used for a socket or a plug, and includes at least two charging terminals 1, at least two cables 2 and a heat conductor 3. The cable 2 includes a wire 210 and a heat exchange tube 220. The heat exchange tube 220 is used for circulating a cooling medium. Each charging terminal 1 is connected to the wire 210 of at least one cable 2. The heat conductor 3 is provided with a through hole 310. The heat conductor 3 is fixedly connected to the heat exchange tube 220 of at least two cables 2. The through hole 310 is communicated with the heat exchange tube 220. The heat conductor 3 is connected to the charging terminal 1.

[0037] Through the above technical solution, that is, the charging assembly provided by the present invention, the heat-conducting member 3 provided with the through hole 310 is fixedly connected to the heat exchange tubes 220 of at least two cables 2, so that the two heat exchange tubes 220 can be connected through the through hole 310, and the heat-conducting member 3 is also heat-conductively connected to the charging terminal 1, for example, at a direct thermal contact or indirect thermal contact. In this way, while the cooling medium flowing in the heat-exchange tube 220 is used to cool the wire 210 of the cable 2, since the heat-conductive connection with the charging terminal 1 is achieved through the heat-conductive member 3, the contact area between the cooling medium and the charging terminal 1 can be increased through the heat-conductive member 3, and the heating part of the charging terminal 1 can also be cooled and cooled by the cooling medium. In the related art, due to the large resistance at the charging terminal, the heat generated at the charging terminal is the highest temperature in the electrical circuit. The present invention uses the cooling medium to simultaneously cool the charging terminal 1 and the wire 210 of the cable 2, which can effectively reduce the safety problems caused by the high heat generated at the charging terminal and the cable during the vehicle charging process, which is conducive to improving the safety during the charging process. Therefore, the charging assembly provided by the present disclosure can cool the charging terminals and cables at the same time, thereby improving the safety during the charging process.

[0038] It should be noted that the above-mentioned cooling medium can be, for example, cooling water or cooling oil, etc., which can achieve heat dissipation effect by heat exchange. The present disclosure does not make specific limitations on this, and those skilled in the art can adaptively design it according to actual application requirements.

[0039] In some embodiments, the heat conductor 3 may be a ceramic part. Since the ceramic part has the advantages of good high temperature resistance, corrosion resistance and high thermal conductivity, it is conducive to ensuring that the heat conductor 3 works stably for a long time, and can increase the heat dissipation capacity of the cooling medium at the charging terminal 1, thereby improving the heat dissipation effect. Of course, the above-mentioned specific embodiment in which the heat conductor 3 is a ceramic part is exemplary. In other embodiments, the heat conductor 3 may also be prepared by non-metallic heat conductive materials such as graphene, thermal conductive silicone grease, or metal heat conductive materials such as copper and aluminum, and the present disclosure is not limited thereto.

[0040] In addition, in some embodiments, the ceramic part and the heat exchange tube 220 can be connected by a hot melt process, for example, which is simple and efficient, and can ensure that the ceramic part and the heat exchange tube 220 have a high connection reliability. Of course, the above-mentioned hot melt process embodiment is exemplary, and in other embodiments, the ceramic part and the heat exchange tube 220 can also be fixedly connected by laser welding, for example. Those skilled in the art can design adaptively according to actual application requirements, and the purpose is to achieve a stable fixed connection between the ceramic part and the heat exchange tube 220, and the present disclosure is not limited thereto.

[0041] In some embodiments, reference Figure 1and Figure 2 As shown, the charging terminal 1 may have a heat-conducting surface 110 facing the cable 2 and a connecting portion 120 protruding from the heat-conducting surface 110, and the connecting portion 120 is connected to the wire 210, so as to achieve a stable electrical connection between the charging terminal 1 and the wire 210. In addition, the heat-conducting member 3 is connected to the heat-conducting surface 110, for example, at a direct thermal contact or indirect thermal contact, so that the charging terminal 1 is in thermal contact with the heat-conducting member 3, which facilitates the cooling of the charging terminal 1 by the cooling medium flowing in the heat-conducting member 3, reduces the local temperature rise at the charging terminal 1, and improves safety.

[0042] For example, reference Figure 1 As shown, the number of cables 2 can be two, and the two cables 2 are respectively a positive multi-core cable and a negative multi-core cable, and the positive multi-core cable and the negative multi-core cable both include two wires 210 arranged side by side, and the number of charging terminals 1 can also be two, and the two charging terminals 1 include a first charging terminal 140 and a second charging terminal 150, wherein the first charging terminal 140 can be, for example, a positive terminal, and the second charging terminal 150 can be, for example, a negative terminal, so that the ends of the two wires 210 of the positive multi-core cable close to the positive terminal can be electrically connected to the connecting part 120 of the positive terminal by, for example, an ultrasonic welding process, and similarly, the ends of the two wires 210 of the negative multi-core cable close to the negative terminal are electrically connected to the connecting part 120 of the negative terminal by an ultrasonic welding process, thereby achieving a stable electrical connection between the charging terminal 1 and the wire 210, thereby forming an electrical circuit.

[0043] Among them, it should be noted that the material of the above-mentioned wire 210 is not specifically limited in this disclosure. For example, it can be a conductive material such as a copper wire or an aluminum wire, but the present disclosure is not limited to this. In addition, the way in which the above-mentioned charging terminal 1 and the wire 210 are electrically connected by, for example, an ultrasonic welding process is also exemplary. The electrical connection can also be achieved by, for example, laser welding. The present disclosure is not limited to this. The purpose is to achieve a stable electrical connection between the charging terminal 1 and the wire 210. In addition, the specific number of wires 210 in the above-mentioned positive multi-core cable and the negative multi-core cable is not specifically limited in this disclosure. Those skilled in the art can design it adaptively according to actual application requirements.

[0044] In addition, if Figure 1 As shown, the cable 2 may further include an insulating sheath 230 covering the heat exchange tube 220 and the at least one wire 210, and the heat exchange tube 220 and the at least one wire 210 may be arranged side by side, that is, Figure 1It is exemplarily shown that when there are multiple wires 210, the multiple wires 210 can be arranged side by side with the heat exchange tube 220 and all located on one side of the heat exchange tube 220, so that the welding operation between the charging terminal 1 and the wire 210 is convenient, and the installation operation is convenient. The present disclosure is not limited to this.

[0045] Of course, it should be noted that the specific structure and material of the above-mentioned insulating sheath 230 and the heat exchange tube 220 are not specifically limited in the present disclosure. Those skilled in the art can adaptively design them according to actual application requirements. For example, the above-mentioned insulating sheath can be made of insulating materials such as silicone rubber, polyethylene, or polyurethane. In addition, the above-mentioned heat exchange tube 220 can be made of polymer materials such as polytetrafluoroethylene, polyvinylidene fluoride, or polyperfluoropropylene, but the present disclosure is not limited to this.

[0046] In addition, in some embodiments, reference Figure 1 and Figure 2 As shown, the heat conductive member 3 may include a heat conductive pipe 320, and the heat conductive pipe 320 includes, for example, a curved pipe segment 321 that is directly thermally contacted and heat conductively connected to the heat conductive surface 110, so that the contact area between the curved pipe segment 321 and the heat conductive surface 110 can be adaptively designed according to actual application requirements to adjust the contact area between the heat conductive member 3 and the charging terminal 1. In this way, by making the heat conductive pipe 320 directly contact the charging terminal 1, the heating part of the charging terminal 1 can be cooled by the cooling medium flowing through the heat conductive pipe 320, thereby increasing the local active heat dissipation capacity of the charging terminal 1, reducing the local temperature rise at the charging terminal 1, and achieving a good heat dissipation effect.

[0047] For example, Figure 1 As shown, the curved pipe segment 321 can extend along the circumference of the charging terminal 1 and around at least a portion of the connecting portion 120. For example, the portion of the curved pipe segment 321 of the heat pipe 320 located on the first charging terminal 140 configured as the positive terminal can extend along the circumference of the first charging terminal 140 and partially around the connecting portion 120, and the portion of the curved pipe segment 321 of the heat pipe 320 located on the second charging terminal 150 configured as the negative terminal can extend along the circumference of the second charging terminal 150 and partially around the connecting portion 120, so that the heat pipe 320 as a whole can be in an "S" shape, for example, connected between the two heat exchange tubes 220 of the positive multi-core cable and the negative multi-core cable, with a simple structure and low space occupancy.

[0048] Of course, the specific embodiments of the extension arrangement of the above-mentioned heat pipe 320 are exemplary, and the present disclosure is not limited thereto. Those skilled in the art can adaptively design according to actual application requirements. For example, in some embodiments not shown in the figure, the curved pipe segment 321 of the heat pipe 320 located on the first charging terminal 140 configured as the positive terminal can be extended along the circumference of the first charging terminal 140 and around the connecting portion 120 for at least one circle, and the curved pipe segment 321 of the heat pipe 320 located on the second charging terminal 150 configured as the negative terminal can be extended along the circumference of the second charging terminal 150 and around the connecting portion 120 for at least one circle. That is, it can be understood that those skilled in the art can adaptively design the size of the contact area between the curved pipe segment 321 of the heat pipe 320 and the heat conductive surface 110 of the charging terminal 1 according to actual application requirements, thereby ensuring a higher cooling effect, and the present disclosure does not make specific limitations here.

[0049] In some embodiments, reference Figure 1 As shown, a heat-conducting layer 4 may be provided between the heat-conducting member 3 and the heat-conducting surface 110, so as to realize a heat-conducting connection between the heat-conducting member 3 and the heat-conducting surface 110, such as indirect thermal contact. Exemplarily, the heat-conducting layer 4 may include heat-conducting silicone. Since the heat-conducting silicone has high thermal conductivity, insulation performance and high temperature resistance, it can ensure that there is a high heat exchange capacity between the charging terminal 1 and the heat-conducting member 3, improve the cooling effect of the cooling medium in the heat-conducting member 3 on the charging terminal 1, and since the heat-conducting silicone itself has a certain viscosity, it is beneficial to ensure that the heat-conducting pipe 320 is stably attached to the heat-conducting surface 110 of the charging terminal 1.

[0050] Of course, the specific embodiment in which the above-mentioned heat-conducting layer 4 includes heat-conducting silicone is exemplary. In other embodiments, the heat-conducting layer 4 may also include heat-conducting materials such as thermal grease or thermal glue. Those skilled in the art may design it adaptively according to actual application requirements, and the present disclosure is not limited to this.

[0051] In some embodiments, reference Figure 1 and Figure 2As shown, the charging terminal 1 can have a stopper 130 extending around itself, the stopper 130 has a first side wall surface 131 facing the connecting portion 120, and the heat conducting member 3 is connected to the first side wall surface 131, that is, it can be understood that at least part of the end surface of the first side wall surface 131 is formed as the above-mentioned heat conducting surface 110, and the second side wall surface 132 of the stopper 130 opposite to the first side wall surface 131 is used to stop at the shell 5 of the socket or plug. In this way, by providing the stopper 130, the area of ​​the heat conducting surface 110 can be increased, which is beneficial to increase the contact area between the cooling medium in the heat conducting pipe 320 and the charging terminal 1, thereby improving the cooling effect, and the second side wall surface 132 of the stopper 130 stops at the shell 5 of the socket or plug, so that when, for example, the charging terminal 1 passes through the channel of the shell 5 (which will be described in detail below), the charging terminal 1 can be moved along the Figure 4 The axis limit in the first direction shown in the figure is used to realize the limited fixation of the charging terminal 1, and the overall integration degree is higher, which is beneficial to reduce the number of parts in the charging component and facilitate the lightweight design of the charging component.

[0052] It should be noted that the present disclosure does not limit the specific structure of the stopper 130, and those skilled in the art can design it adaptively according to actual application requirements, for example, it can be as follows: Figure 1 The purpose of the annular flange structure or rectangular flange structure provided at the outer periphery of the charging terminal 1 shown in the figure is to increase the area of ​​the heat conducting surface 110 and improve the contact area between the cooling medium in the heat conducting pipe 320 and the charging terminal 1. The present disclosure is not limited thereto.

[0053] According to a second aspect of the present disclosure, a socket is provided, which includes the above-mentioned charging assembly, so as to achieve cooling of the charging terminal and the cable of the socket, thereby improving the safety during the charging process. In addition, the socket also has all the beneficial effects of the above-mentioned charging assembly, which will not be repeated in this disclosure.

[0054] In some embodiments, reference Figures 1 to 4 As shown, the socket may include a shell 5, and the charging terminal 1 is inserted into the shell 5. A limiting structure 510 is provided on the shell 5. The limiting structure 510 is used to stop the heat conductor 3, so as to achieve the limiting fixation of the heat conductor 3 and reduce the movement of the heat conductor 3, which is beneficial to reducing the amount of bubbles in the cooling medium in the through hole 310 of the heat conductor 3 and improving the cooling effect.

[0055] For example, reference Figures 1 to 4 As shown, the limiting structure 510 may include a first limiting portion 511 and a second limiting portion 512, and the first limiting portion 511 and the second limiting portion 512 are stopped at opposite sides of the heat conductive member 3, so that the first limiting portion 511 and the second limiting portion 512 can jointly limit the movement of the heat conductive member 3.

[0056] in, Figures 1 to 4 The at least two charging terminals 1 may include a first charging terminal 140 and a second charging terminal 150, and the housing 5 has a first channel 520 for inserting the first charging terminal 140 and a second channel 530 for inserting the second charging terminal 150. Since the first charging terminal 140 and the second charging terminal 150 both have a stopper 130 extending around their own axial direction, when the first charging terminal 140 is inserted into the first channel 520 and the second charging terminal 150 is inserted into the second channel 530, the second side wall surface 132 of the stopper 130 can stop the housing 5, so that the charging terminal 1 can be inserted along the first channel 520 and the second charging terminal 150 can be inserted into the second channel 530. Figure 4 The axis of the first direction shown in the figure is limited to achieve the limited fixation of the charging terminal 1.

[0057] In addition, refer to Figures 2 to 3 As shown, the first limiting portion 511 may include a first protrusion 5111 extending around the circumference of the channel opening of the first channel 520, and the second limiting portion 512 includes a second protrusion 5121 extending around the circumference of the channel opening of the second channel 530. In this way, by directly utilizing the partial outer peripheral areas of the respective channel openings of the first channel 520 and the second channel 530 to form the first protrusion 5111 and the second protrusion 5121, respectively, the heat conductor 3 can be fitted to the first protrusion 5111 and the second protrusion 5121, and not only can the first protrusion 5111 and the second protrusion 5121 respectively realize radial constraints on the first charging terminal 140 inserted into the first channel 520 and the second charging terminal 150 inserted into the second channel 530, but also radial constraints on the heat conductor 3 can be realized to prevent the heat conductor 3 from radial movement. The high degree of integration is beneficial to reducing the number of components in the charging assembly and facilitating the lightweight design of the charging assembly.

[0058] In addition, reference Figures 2 to 3As shown, the shell 5 can have a signal channel 540 for the signal terminal to pass through, and the first limiting portion 511 can also include a third protrusion 5112 and a fourth protrusion 5113 extending around the periphery of the channel mouth portion of the signal channel 540, and the heat conductor 3 is attached to the third protrusion 5112 and the fourth protrusion 5113, and the fourth protrusion 5113 and the first protrusion 5111 can be connected as a whole and have a common portion that surrounds both the periphery of the channel mouth portion of the first channel 520 and the periphery of the channel mouth portion of the signal channel 540, thereby further improving the reliability of the heat conductor 3, and the overall structure is simple and easy to install and manufacture. Of course, the fourth protrusion 5113 and the first protrusion 5111 can also be arranged independently, and the present disclosure does not make specific limitations on this. In addition, since the third protrusion 5112 and the fourth protrusion 5113 can be directly formed at the outer peripheral area of ​​the channel opening of the signal channel 540 through which the signal terminal passes, the structure is more compact and highly integrated, which is beneficial to reducing the number of components in the charging assembly and facilitating the lightweight design of the charging assembly.

[0059] Or, in other embodiments, reference Figures 2 to 3 As shown, the shell 5 can have a grounding channel 550 for the protection terminal to pass through, and the second limiting portion 512 can also include a fifth protrusion 5122 extending around at least a portion of the periphery of the channel opening of the grounding channel 550. The thermal conductor 3 is attached to the fifth protrusion 5122, so that the reliability of the thermal conductor 3 can be further improved. In addition, by directly utilizing the outer peripheral area of ​​the channel opening of the grounding channel 550 for the protection terminal to pass through, the above-mentioned fifth protrusion 5122 is formed, and the structure is more compact and highly integrated.

[0060] Of course, it should be noted that the above-mentioned first limiting portion 511 can also include a third protrusion 5112 and a fourth protrusion 5113 extending around the peripheral edge of the channel opening of the signal channel 540 to achieve limiting fixation of the heat conductor 3, and the second limiting portion 512 can also include a fifth protrusion 5122 extending around at least a portion of the peripheral edge of the channel opening of the grounding channel 550 to achieve limiting fixation of the heat conductor 3. The two specific embodiments can be arranged simultaneously or separately, and the present disclosure does not make specific limitations on this.

[0061] In addition, the present disclosure does not specifically limit the specific appearance structure of the above-mentioned shell 5. Those skilled in the art can adaptively design it according to actual application requirements. For example, it can be constructed as a DC charging socket shell structure known in the art, that is, it can be understood that the above-mentioned first channel 520 can be a channel for installing the first charging terminal (such as the positive charging terminal) 140, the second channel 530 is a channel for installing the second charging terminal (such as the negative charging terminal) 150, the signal channel 540 is a channel for installing the signal terminal (such as the CC1 identification terminal or the CC2 identification terminal), and the grounding channel 550 is a channel for installing the protection terminal (such as the PE terminal). Since the channels for installing each terminal and each terminal of the above-mentioned DC charging socket shell structure are structures known in the art, the present disclosure will not be elaborated on herein.
