[0039] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] An electric vehicle (EV) is a vehicle driven by an electric motor and mainly stores electrical energy through batteries. Depending on the power source of the electric vehicle, it can be divided into pure electric vehicles, hybrid electric vehicles, extended-range electric vehicles, etc. It has the advantages of energy saving, environmental protection, low noise and high efficiency.

[0041] As the electric vehicle market expands, the demand for electric vehicle charging infrastructure is also growing. Consequently, the application scenarios for electric vehicle charging infrastructure are also gradually expanding. In addition to traditional public charging stations, charging sockets in homes, commercial buildings, and highway service areas are also becoming increasingly popular.

[0042] Specifically, the charging infrastructure for electric vehicles includes a charging socket, which is responsible for transmitting electrical energy from the charging station or power grid to the electric vehicle's battery. The charging socket is made of a conductive material with a certain resistance. When the charging socket is connected to a circuit and in operation, current flows through the charging socket. Due to the resistance of the charging socket, the thermal effect of the current causes heat to be generated by the components inside the charging socket. This heat is then transferred to the charging socket, causing it to heat up.

[0043] However, over time, the charging socket may overheat due to internal dust accumulation, excessive current, high ambient temperature, and other factors. Excessive heating of the charging socket exposes it to high temperatures, which can cause internal metal contacts and insulation materials to age, lose their original performance, become fragile, or even fail. This increases the risk of faults such as poor contact and short circuits, shortening the charging socket's service life.

[0044] What is more serious is that if the charging socket overheats and is not controlled in time, the high temperature may ignite the charging socket and flammable materials around it, causing a fire, resulting in property damage and even threatening personal safety.

[0045] In view of this, the present application provides a socket. When an electric vehicle is charging, the conductive parts in the socket will generate heat due to the passage of current. The heat will be absorbed by a cooling module and conducted to its surface. The cooling module can conduct the heat away through natural heat dissipation or active heat dissipation, thereby reducing the temperature inside the socket. The socket design with a cooling module achieves effective heat dissipation and effectively controls the socket temperature, preventing aging of the socket's internal structure due to overheating, maintaining good conductivity of the conductive parts, extending the socket's service life and safety, and enhancing its stability and reliability, ensuring the socket's safe use.

[0046] The following combination Figures 1 to 3 The socket according to the embodiment of the present application is described.

[0047] Combine Figure 1 The socket of this embodiment can be used in electric vehicles. The socket can include a housing 100, a conductive member 200, and a cooling module 300.

[0048] The inner side of the shell 100 has an accommodating cavity 100 a for accommodating various components inside the socket. The side of the shell 100 is provided with an installation space communicating with the accommodating cavity 100 a for installing and fixing the cooling module 300 .

[0049] The conductive member 200 is used to connect the wiring harness cable and is responsible for the transmission of current. For example, the conductive member 200 is connected to the wiring harness cable by welding. The conductive member 200 is arranged in the accommodating cavity 100a, and the cooling module 300 is fixedly arranged in the installation space. The cooling module 300 maintains thermal contact with the conductive member 200, and realizes thermal management of the socket by absorbing and conducting the heat generated by the conductive member 200.

[0050] Specifically, when an electric vehicle is charging, the conductive element 200 in the socket generates heat due to the current flowing through it. This heat is absorbed by the cooling module 300 and conducted to its surface. The cooling module 300 can then conduct the heat away through natural or active cooling, thereby reducing the temperature inside the socket. For example, natural cooling can be achieved by installing a heat sink, while active cooling can be achieved by installing a fan or liquid cooling assembly.

[0051] Through the socket design with the cooling module 300, effective heat dissipation of the socket is achieved, the socket temperature is effectively controlled, the internal structure of the socket is prevented from aging due to overheating, the conductive part 200 maintains good conductive performance, the service life and safety of the socket are improved, and its stability and reliability are enhanced, thereby ensuring the safe use of the socket.

[0052] Furthermore, the socket of this embodiment has increased current carrying capacity. For example, compared to a conventional socket without cooling module 300, the socket of this embodiment can replace the current carrying capacity of two conventional sockets. For example, if the current carrying capacity of a transmission socket is 400A, the current carrying capacity of the socket of this embodiment is 800A, thus reducing the number of sockets required when using high-power charging currents.

[0053] In some embodiments, combined Figure 1 and Figure 2 The cooling module 300 includes a cooling body 310, which defines a heat exchange cavity. The heat exchange cavity is a place where the cooling medium performs heat exchange. The heat exchange cavity has a liquid inlet 310a and a liquid outlet 310b. The heat exchange cavity forms a heat exchange circulation loop with the external liquid supply device through the liquid inlet 310a and the liquid outlet 310b. The liquid inlet 310a and the liquid outlet 310b allow the cooling medium to enter and leave the heat exchange cavity, forming a continuous circulation flow.

[0054] A cooling medium circulates in the heat exchange circulation loop, the cooling body 310 is fixedly connected to the shell 100, and the cooling body 310 is in contact with the conductive member 200. The cooling medium is a liquid or gas circulating in the heat exchange circulation loop, which is used to absorb and take away the heat generated by the conductive member 200. For example, the cooling medium can be water or coolant.

[0055] Specifically, when the electric vehicle is charging, the conductive part 200 in the socket generates heat due to the passage of current. Due to the contact between the cooling body 310 and the conductive part 200, the heat will be transferred to the cooling body 310. The cooling medium is pumped into the liquid inlet 310a of the heat exchange chamber through the external liquid supply device. In the heat exchange chamber, the cooling medium exchanges heat with the cooling body 310, absorbs the heat from the cooling body 310 and heats up. After absorbing the heat, the cooling medium flows out through the liquid outlet 310b and returns to the external liquid supply device for cooling treatment, such as dissipating heat through a radiator. The cooled cooling medium is then pumped into the liquid inlet 310a again, thereby forming a continuous heat exchange cycle.

[0056] The above-mentioned cooling module 300 continuously circulates and exchanges heat through the cooling medium, so that the cooling medium can effectively take away the heat generated by the conductive part 200, thereby reducing the temperature inside the socket, realizing the management and control of the heat generated during the operation of the socket, and ensuring that the socket can effectively dissipate heat when working under high load, thereby protecting internal components and extending service life.

[0057] In some embodiments, combined Figure 1 and Figure 2 The cooling body 310 includes a first body portion 311 and a second body portion 312. The first body portion 311 defines a liquid inlet cavity, which is the initial location where the cooling medium enters the heat exchange circulation loop and is used to receive cooling medium from an external liquid supply device. The second body portion 312 defines a liquid outlet cavity, which is used to discharge the cooling medium that has absorbed heat from the heat exchange circulation loop and return it to the external liquid supply device for cooling. The liquid inlet and outlet cavities are arranged sequentially along the flow direction of the cooling medium and are connected. The liquid inlet 310a is located in the first body portion 311, and the liquid outlet 310b is located in the second body portion 312.

[0058] Specifically, the cooling medium enters the liquid inlet cavity of the first main body part 311 through the liquid inlet 310a, then enters the liquid outlet cavity of the second main body part 312 along the set flow path, and is finally discharged through the liquid outlet 310b. During this process, the cooling medium exchanges heat with the first main body part 311 and the second main body part 312, absorbing and taking away the heat on their surfaces.

[0059] There are at least two conductive members 200 , which are used to connect to the wiring harness. One of the at least two conductive members 200 contacts the first main body 311 , and the other contacts the second main body 312 . This ensures that the conductive members 200 can dissipate heat through the cooling body 310 .

[0060] When the conductive member 200 generates heat during operation, the heat will be conducted to the portion of the cooling body 310 in contact therewith and carried away by the circulating flow of the cooling medium, thereby achieving management and control of the heat inside the socket and improving the heat dissipation performance and service life of the socket.

[0061] In some embodiments, combined Figure 1 and Figure 3 The cooling module 300 also includes a cooling cover 320, which is arranged on the outside of at least part of the cooling body 310. The cooling body 310 is in thermal contact with the conductive member 200 through the cooling cover 320, so that the cooling body 310 can effectively be in thermal contact with the conductive member 200, ensuring that the heat generated by the conductive member 200 can be transferred to the cooling body 310 and then carried away by the cooling medium, thereby realizing thermal contact between the cooling body 310 and the conductive member 200 and improving the heat dissipation effect.

[0062] Optionally, combined Figure 1 and Figure 3 The cooling cover 320 includes a first cover 321 and a second cover 322 , and the first cover 321 and the second cover 322 are respectively covered on the first main body 311 and the second main body 312 .

[0063] Exemplarily, the cooling cover 320 is a ceramic part. Due to the high thermal conductivity of the ceramic material, the cooling cover 320 can effectively transfer the heat generated by the conductive part 200 to the cooling body 310, thereby improving the heat dissipation efficiency. In addition, the insulating properties of the ceramic material ensure electrical isolation between the conductive parts 200, reducing the risk of safety hazards such as short circuits and electric shocks.

[0064] In some embodiments, combined Figure 1 The cooling body 310 is a metal part. The thermal conductivity of the metal can realize the effective transfer of heat and improve the heat dissipation efficiency. The socket also includes a grounding conductor, which ensures the electrical safety of the socket. The grounding conductor is arranged in the accommodating cavity 100a and is connected to the cooling body 310.

[0065] The grounding conductor is connected to the cooling body 310 to connect the electrical system inside the socket to the ground, ensuring that when a fault such as leakage or short circuit occurs, the current can flow into the ground through the grounding conductor to avoid harm to the human body and equipment. The cooling module 300 not only improves the heat dissipation efficiency of the socket but also improves the electrical safety performance.

[0066] In addition, by connecting the cooling module 300 and the grounding conductor, the cooling module 300 utilizes part of the space where the grounding conductor is located, avoiding the occupation of additional space. Even if the cooling module 300 is installed, the size of the socket remains unchanged compared to the traditional socket, ensuring the full utilization of the space inside the socket and improving the overall compactness of the socket.

[0067] In some embodiments, combined Figure 1 The installation space includes a mounting groove, which is open toward the side of the shell 100, so that the cooling body 310 is inserted into the mounting groove through the shell 100. A connecting edge 313 is provided on the peripheral side of the cooling body 310, and the connecting edge 313 is fixedly connected to the end face of the open end of the mounting groove. Exemplarily, a variety of fixing methods can be used between the connecting edge 313 and the end face of the open end of the mounting groove, such as bolt connection, snap connection, welding, etc. The specific selection can be made according to actual needs and is not limited here.

[0068] The setting of the connecting edge 313 plays a fixing role and also serves as a heat dissipation surface. Through contact with the mounting groove, the connecting edge 313 can transfer part of the heat to the shell 100, and then dissipate it to the surrounding environment through the heat dissipation surface of the shell 100, which helps to further improve the heat dissipation effect of the socket.

[0069] In some embodiments, combined Figure 1 and Figure 2 The end face of the opening of the mounting groove is provided with a first connecting hole, and the connecting edge 313 is provided with a second connecting hole 3131. The cooling body 310 and the shell 100 are connected by fasteners 500 that pass through the first connecting hole and the second connecting hole 3131 in sequence. Exemplarily, the fasteners 500 can be bolts, screws, etc.

[0070] The cooling body 310 and the housing 100 are connected and fixed by fasteners 500, which ensures that the socket will not loosen or fall off due to vibration or external force during operation, thereby improving the overall structural stability and reliability of the socket. Figure 1 The socket further includes a seal 400, which is disposed between the cooling body 310 and the housing 100. The provision of the seal 400 prevents dust, moisture, oil and other impurities from entering the interior of the socket, thereby protecting the electrical components inside the socket and extending the service life of the socket.

[0071] In some embodiments, combined Figure 1 and Figure 3 A limiting protrusion 410 is provided at one end of the sealing member 400 facing the cooling cover body 320, and a limiting groove 320a is provided on the outer wall of the cooling cover body 320. The cooling cover body 320 is configured so that when the cover is placed on the cooling body 310, the limiting protrusion 410 is arranged in the limiting groove 320a. Exemplarily, the limiting protrusion 410 can be nearly circular, nearly square or irregular in shape, and the limiting groove 320a is adaptively adjusted according to the shape of the limiting protrusion 410, and the specific shape is not limited.

[0072] It can be seen that when the cooling cover body 320 is covered on the cooling main body 310, the limiting protrusion 410 will be embedded in the limiting groove 320a, which can ensure that the position of the cooling cover body 320 in the closed state is accurate and stable, improve the structural stability and sealing performance of the socket, and ensure the working state and electrical safety of the socket.

[0073] In some embodiments, combined Figure 1 The shell 100 includes a first shell 110, a second shell 120 and a third shell 130 arranged and connected in sequence along a first direction. For example, the first shell 110 and the second shell 120 can be connected by a snap, and the second shell 120 and the third shell 130 can be connected by a thread. Any method of achieving a detachable connection between the two is within the scope of protection of this application and is not limited here.

[0074] Among them, the first shell 110 is provided with a plug port 111 at one end away from the second shell 120 along the first direction. The plug port 111 realizes the connection between the socket and an external device, such as a charging gun. The grounding conductor is provided on the first shell 110 to ensure that when the device is inserted, the grounding connection can be established first to ensure the safety of the electrical system.

[0075] The second housing 120 primarily houses the socket's internal electrical components and heat dissipation structure. One end of the conductive member 200 is snap-fitted to the first housing 110, allowing the conductive member 200 to be positioned within the second housing 120 for electrical connection and signal transmission. An installation space is provided on the side of the second housing 120 to facilitate installation and removal of components such as the cooling body 310.

[0076] The third shell 130 is provided with a wire hole 131 opposite to the plug port 111. The wire hole 131 is used for the wiring harness to pass through. Optionally, a sealing ring is provided inside the third shell 130 to seal the gap between the wiring harness and the third shell 130 to prevent impurities such as dust and moisture from entering the interior of the socket.

[0077] By dividing the housing 100 into a first housing 110 , a second housing 120 and a third housing 130 , a segmented design of the socket is achieved, making the overall structure of the socket more compact and easier to maintain. In addition, it helps to improve the heat dissipation performance and electrical safety of the socket.
