[0037] This utility model proposes a charging socket. Please refer to... Figures 1 to 7 The device includes: a socket housing 1, which has several outlet holes; a mounting assembly 3, which is detachably connected to the socket housing 1, and a mounting cavity is formed between the mounting assembly 3 and the socket housing 1. The mounting assembly 3 has several mounting holes communicating with the mounting cavity, and the mounting holes and outlet holes are coaxially arranged; a terminal assembly 2, which includes several power terminals 21, which are installed in the mounting holes, with one end extending into the outlet hole and the other end extending out of the mounting assembly 3. The end of the power terminal 21 extending out of the mounting assembly 3 has a copper busbar 211 connected to the power supply equipment; and a temperature control assembly 4, which is located in the mounting cavity and is used to monitor the temperature rise of the terminal assembly 2.

[0038] In this embodiment, a mounting cavity is provided between the socket housing 1 and the mounting assembly 3, and the terminal assembly 2 is disposed in the mounting cavity. The socket housing 1 and the mounting assembly 3 are detachably connected, facilitating the disassembly of the terminal assembly 2. The socket housing 1 has multiple cable outlet holes. During the use of the charging socket, an external charging plug is inserted into the cable outlet hole, making the external charging plug conductively connected to the terminal assembly 2 to achieve current flow. The mounting hole of the mounting assembly 3 is coaxially arranged with the cable outlet hole, facilitating the fixed installation of the terminal assembly 2. The terminal assembly 2 has multiple power terminals 21. One end of the power terminal 21 has a plug-in mating part, which is inserted into the socket housing 1 and connected to the external charging gun pin to achieve conductivity; the other end of the power terminal 21 has a copper busbar 211, which has a parallel upper plane and a lower plane. A connection hole extending from the upper plane to the lower plane is opened on the copper busbar 211. When the charging socket is connected to an external power supply device, a conductive element is provided in the connection hole to connect with the external power supply device. Traditional charging sockets use a crimping method where the power wire is crimped to the charging base terminals and the copper lug at the end. Understandably, the copper busbar 211 structure at one end of the power terminal 21 reduces the types of transmission media compared to a wire crimping structure. The heat exchange sequence is reduced from copper-insulation-outer shell-external environment to copper-outer shell-external environment, effectively improving heat dissipation efficiency. The charging socket also includes a temperature control component 4, located within the mounting cavity near the terminal assembly 2, for monitoring the temperature rise of the terminal assembly 2. Preferably, multiple power terminals 21 can be adapted to different temperature control schemes. Appropriately selecting a temperature control scheme based on different usage environments can reduce costs and increase temperature control stability.

[0039] This utility model provides an embodiment, please refer to it. Figure 1 The socket housing 1 includes an integrally formed upper housing 11 and a lower housing 12, and the upper housing 11 and the lower housing 12 are respectively provided with a plurality of wire outlet holes; the mounting assembly 3 includes a first tail cover 31 and a second tail cover 32, the first tail cover 31 is detachably connected to the upper housing 11, and the second tail cover 32 is detachably connected to the lower housing 12; a first cavity is formed between the upper housing 11 and the first tail cover 31, and a second cavity is formed between the lower housing 12 and the second tail cover 32.

[0040] Specifically, the charging socket has two socket assemblies, upper and lower, allowing both assemblies to connect to external power simultaneously. Depending on the application scenario, each socket assembly can be configured with various power supply schemes. The upper socket assembly includes an upper housing 11, a first tail cover 31, and a portion of the terminal assembly 2. The upper housing 11 and the first tail cover 31 are detachably connected, and a housing sealing ring is provided between them to achieve a sealed connection, effectively improving the charging socket's waterproof and foreign object-proof capabilities and preventing abnormal problems during charging. A first cavity is formed between the upper housing 11 and the first tail cover 31, and a portion of the power terminal 21 is inserted into this cavity. The upper housing 11 has multiple cable outlet holes, and the insertion and mating part of one end of the power terminal 21 is inserted into the cable outlet hole for connection with the external charging gun port. The first tail cap 31 has multiple mounting holes coaxially formed with the multiple cable outlet holes of the upper housing 11. Power terminals 21 are inserted into the mounting holes, and copper busbars 211 extend out of the first tail cap 31 to connect with external power supply equipment. The terminal assembly 2 also includes a signal terminal 22 and a PE terminal 23 installed in the first cavity. One end of the signal terminal 22 and the PE terminal 23 is inserted into the cable outlet hole, and the other end of the PE terminal 23 is correspondingly inserted into the mounting hole. The socket assembly of the lower part of the charging socket includes a lower housing 12, a second tail cap 32, and part of the terminal assembly 2. The lower housing 12 and the second tail cap 32 are detachably connected and form a second cavity between them. Several power terminals 21 are installed in the second cavity. Further, two power terminals 21 are arranged side by side in the second cavity. The lower housing 12 has multiple cable outlet holes. The insertion mating parts of one end of the two power terminals 21 are inserted into the cable outlet holes of the lower housing 12 and connected with the external charging gun socket. The second tail cover 32 has multiple mounting holes coaxially formed with the multiple cable outlet holes of the lower housing 12. Power terminals 21 are inserted into the mounting holes, and copper busbars 211 extend out of the second tail cover 32 to connect to external power supply equipment. It is understandable that the upper and lower socket assemblies are powered independently, allowing for the simultaneous provision of different power supply solutions.

[0041] Further, please refer to Figure 2 The mounting hole is provided with multiple claws 311 for fixing the power terminal 21.

[0042] Understandably, the mounting hole has several protruding claws 311, which are distributed circumferentially along the inner wall of the mounting hole and surround the outer wall of the power terminal 21 to limit and fasten the power terminal 21. Furthermore, this design allows for flexible installation and disassembly, effectively reducing the probability of defective products during assembly.

[0043] Furthermore, a wire guide plate 5 and a wire sealing body 6, which are sleeved on the power terminal 21, are sequentially provided between the lower housing 12 and the second tail cover 32.

[0044] Specifically, two power terminals 21 are arranged side by side in the second cavity. A wire guide plate 5 is positioned between the two power terminals 21, and grooves are provided on the left and right sides of the wire guide plate 5 facing the power terminals 21. The two power terminals 21 are respectively clamped in the left and right grooves of the wire guide plate 5 to achieve limited installation of the power terminals 21. The sealing body 6 is made of insulating material, and several wire holes are opened on the sealing body 6 corresponding to the positions of the power terminals 21. In this embodiment, the sealing body 6 has two wire holes. It can be understood that the wire holes are coaxially arranged corresponding to the mounting holes of the second tail cover 32 and the outlet holes of the lower housing 12. Each power terminal 21 passes through the outlet hole, the wire hole, and the mounting hole in sequence. The sealing body 6 is sleeved on the outer wall of the power terminal 21 to ensure that the power terminal 21 passes through while achieving sealed installation. Furthermore, slots are provided at corresponding positions in the middle of the wire threading plate 5 and the sealing body 6, and an insert plate is protruding from the second tail cover 32 corresponding to the positioning slot. The insert plate is inserted into the slot, thereby limiting and pressing the wire threading plate 5 and the sealing body 6 inside the lower housing 12. Preferably, the outer peripheral wall of the sealing body 6 and the inner wall of the wire threading hole are provided with annular protrusions at intervals, so that the sealing body 6 is in close contact with the power terminal 21 and the lower housing 12, ensuring the sealing performance of the charging socket.

[0045] Further, please refer to Figure 1 and Figure 2 The temperature control component 4 includes: a PCB board 41, which is disposed in the first cavity. The PCB board 41 also has several through holes for the terminal component 2 to pass through. The PCB board 41 is provided with a surface-mount resistor for temperature measurement and a temperature control circuit; and a low-voltage connector 42, which is installed on the upper housing 11 and electrically connected to the PCB board 41.

[0046] Specifically, PCB board 41 refers to a printed circuit board, which can be implemented using a composite structure of glass fiber substrate and copper foil circuitry, serving as a mounting carrier and electrical connection medium for electronic components. Its function is to provide a mechanical fixation and electrical interconnection foundation for the temperature sensor, while also supporting the charging control circuitry. PCB board 41 is located between the upper housing 11 and the first tail cover 31, sleeved outside the partial terminal assembly 2, and has several through holes, with power terminals 21 and PE terminals correspondingly inserted into these holes. Multiple mounting posts are provided on the side of PCB board 41 facing away from the first tail cover 31, and these mounting posts are correspondingly inserted into multiple signal terminals 22. The temperature sensor refers to a temperature-sensitive element. In this embodiment, the temperature sensor is a surface-mount resistor, integrated onto the surface of PCB board 41 through soldering or surface mounting. Its function is to sense changes in the circuit board's operating temperature in real time through direct contact with the PCB copper foil. Preferably, the surface-mount resistor is positioned near the through holes. Understandably, the PCB board 41 integrates signal lines and temperature control circuitry. The low-voltage connector 42 is located on the upper housing 11 and electrically connected to the PCB board 41 to achieve signal transmission and output, effectively increasing the stability of electrical functions. When a large current flows through the power terminal 21 during charging, the generated Joule heat is conducted to the PCB board 41 through the metal, and the surface-mount resistor directly detects the temperature change in this area. The detection signal is transmitted to the low-voltage connector 42 through the internal traces of the PCB board 41. When the temperature exceeds a preset threshold, an over-temperature protection mechanism can be triggered, such as reducing the charging power or cutting off the power supply. Using the PCB board 41 to realize signal transmission and temperature detection inside the charging socket greatly reduces the complexity of the internal wiring layout of the charging socket, and the connection with the low-voltage connector 42 through the adapter pins enhances the sealing of the internal environment of the charging socket and the safety during operation.

[0047] Further, please refer to Figure 1 The temperature control component 4 also includes a thermistor 43, which is a cylindrical resistor with one end inserted into the second cavity. The thermistor 43 is installed near the copper busbar 211.

[0048] Specifically, the second tail cover 32 contains a cylindrical encapsulated thermistor 43, which is installed in the middle of the copper busbar 211, allowing for timely monitoring of the temperature rise at the tail of the power terminal 21. This also effectively reduces processing steps and simplifies the assembly process of the charging socket.

[0049] Further, please refer to Figure 1 The socket housing 1 has several drainage grooves 1a.

[0050] Specifically, the side walls of the upper housing 11 and the lower housing 12 are provided with a plurality of drainage grooves 1a. The drainage grooves 1a are located near the cable outlet holes to guide water accumulated inside the socket housing 1 to the outside of the socket housing 1, preventing water from stagnating inside the cable outlet holes and causing oxidation and corrosion of the terminal assembly 2. The drainage grooves 1a effectively improve the service life of the charging socket and ensure its safety and stability.

[0051] Further, please refer to Figure 1 The charging socket also includes a flip cover assembly 8, which is fixedly connected to the socket housing 1. The flip cover assembly 8 includes a mounting plate, and the side of the mounting plate away from the socket housing 1 is also provided with a first flip cover and a second flip cover that can be opened and closed separately.

[0052] Specifically, the mounting plate is fixedly mounted on the socket housing 1 using countersunk screws. One end of the first and second flip covers is rotatably mounted on the mounting plate, allowing the first and second flip covers to be opened and closed. It is understood that the first flip cover corresponds to the position of the cable outlet of the upper housing 11, and the second flip cover corresponds to the position of the cable outlet of the lower housing 12. The flip cover assembly 8 prevents dust and water from entering the socket housing 1 when the charging socket is not in use. Preferably, a sealing gasket is provided on the inner side of the first and second flip covers to further improve the sealing performance of the charging socket.

[0053] Further, please refer to Figure 1 A sealing cap 7 is installed on the end of the mounting component 3 away from the socket housing 1.

[0054] Specifically, the power terminal 21 is inserted into the mounting hole of the mounting component 3, the copper busbar 211 extends out of the mounting component 3, and a sealing cover 7 is fitted over the connection between the copper busbar 211 and the mounting component 3. The sealing cover 7 is connected to the mounting component 3 and has a through hole for the power terminal 21 to pass through. The sealing cover 7 covers the entrance area of ​​the mounting hole, and the through hole is coaxial with the mounting hole. The power terminal 21 passes through both the mounting hole and the through hole of the sealing cover. This structural design effectively achieves a seal and improves the safety and stability of the charging socket. Preferably, the side wall of the sealing cover 7 has multiple latches, and the mounting component 3 has corresponding latching protrusions. The latches and latching protrusions engage one-to-one, realizing a detachable connection between the mounting component 3 and the sealing cover 7 and improving connection stability.
