Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0030] As the driving range of power batteries increases, batteries become larger, and automotive electronic devices become more numerous and space becomes more compact, the integration and lightweighting of automotive internal management systems have become a trend.

[0031] The electric vehicle control system, acting as the "brain" of the vehicle, receives commands from the vehicle to control the output torque and speed of the motor. It also controls various electronic systems, such as multimedia, navigation, and audio, ensuring coordinated operation. To suppress current and voltage surges and reduce electromagnetic interference, a magnetic ring and two filter capacitors are incorporated into the electric vehicle control system. However, due to space constraints, assembling the magnetic ring and filter capacitors is challenging. While magnetic rings and capacitors are typically included in electric vehicle control systems to suppress voltage and current surges and reduce electromagnetic interference, their installation is inconvenient due to limited space.

[0032] In view of this, embodiments of this application provide a connector to overcome at least one of the above-mentioned technical problems.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 8 In this embodiment of the application, the connector includes a housing 10, a shielding assembly 20, a copper busbar assembly 30, and a circuit assembly 40.

[0034] The housing 10 has a receiving groove 11, a through hole 12, and a plurality of connecting holes 17, the through hole 12 communicating with the receiving groove 11. A shielding assembly 20 is connected to the housing 10. The shielding assembly 20 includes a first contact portion 21 and a plurality of second contact portions 22. The first contact portion 21 is disposed within the through hole 12 and the receiving groove 11. At least one second contact portion 22 passes through each connecting hole 17, and the plurality of second contact portions 22 are connected to the cover plate 80. A copper busbar assembly 30 is connected to the housing 10. The copper busbar assembly 30 includes an elastic portion 31, at least a portion of which is disposed within the receiving groove 11. A circuit assembly 40 is disposed within the receiving groove 11. The circuit assembly 40 includes a connected plate body 41 and a capacitor portion 42. The capacitor portion 42 includes a first connecting end 421 and a second connecting end 422 (e.g., ...). Figure 9As shown, the first connecting end 421 is connected to the elastic part 31, and the second connecting end 422 is connected to the first contact part 21.

[0035] Understandably, installing one or more capacitors in an electric vehicle control system is difficult, increasing assembly complexity and reducing efficiency. Therefore, the capacitor can be placed inside the male terminal of the connector, allowing it to be integrated directly onto the connector's male terminal during manufacturing. During the assembly of the electric vehicle control system, no further capacitor is needed; the capacitor within the connector still effectively reduces electromagnetic interference.

[0036] like Figure 4 and Figure 5 As shown, the male end of the connector has a housing 10, and the front side of the housing 10 has a receiving groove 11, as... Figure 1 and Figure 6 As shown, a cavity is provided on the back of the housing 10 for embedding the main body of the shielding assembly 20, facilitating connection between the shielding assembly 20 and the housing 10. Through holes 12 are also provided on the housing 10, connecting the receiving groove 11 on the front of the housing 10 to the cavity on the back of the housing 10. The number of through holes 12 is the same as the number of shielding assemblies 20. Figure 1 If there are two shielding components 20, then two through holes 12 are provided on the housing 10 to facilitate at least a portion of the first contact portion 21 on the shielding component 20 to pass through the corresponding through hole 12 and be embedded into the receiving groove 11. The first contact portion 21 can be a pin structure on the shielding component 20. Figure 1 , Figure 2 and Figure 13 As shown, copper busbar assemblies 30 are also connected to the housing 10, and the number of copper busbar assemblies 30 is the same as the number of shielding assemblies 20. The elastic portion 31 on the copper busbar assembly 30 is at least partially embedded in the receiving groove 11. The elastic portion 31 can be a metal spring, connected to the main body of the copper busbar assembly 30 by rivets. A circuit assembly 40 is disposed inside the receiving groove 11, such as... Figure 9 As shown, the circuit assembly 40 is provided with a corresponding circuit structure, including capacitor sections 42 (the capacitor sections 42 are Y-type filter capacitors) in the same number as the shielding assembly 20 and the copper busbar assembly 30, and also includes a board 41. The capacitor sections 42 are disposed on the board 41, which can be a PCB circuit board with corresponding circuits connected to the capacitor sections 42. Figure 7 and Figure 9As shown, the capacitor section 42 has a first connection end 421 and a second connection end 422. The first connection end 421 is electrically connected to the elastic section 31, and the second connection end 422 is electrically connected to the first contact section 21. Multiple second contacts 22 (equivalent to multiple pin structures) on the shielding assembly 20, after passing through corresponding connection holes 17, are bent to a certain extent and then connected to the metal cover plate 80 on the connector to achieve grounding, thereby forming a corresponding circuit structure. The size and position of the connection holes 17 can be set as needed. The position of the connection hole 17 corresponds to the position of the second contact section 22. One second contact section 22 can pass through one connection hole 17, or multiple second contacts 22 can pass through it. When current flows through the copper busbar assembly 30, the capacitor section 42, and the shielding assembly 20, this circuit structure can absorb transient voltage changes (such as surge voltage) between the copper busbar assembly 30 and the shielding assembly 20, balance the potential difference, thereby reducing the local magnetic field strength, reducing electromagnetic interference, and preventing insulation breakdown caused by arc discharge. At the same time, high-frequency interference on the copper busbar assembly 30 will be quickly guided to the shielding assembly 20, effectively improving electromagnetic compatibility.

[0037] During the processing of the male terminal of the connector, a corresponding number of capacitor sections 42 can be directly integrated onto the board body 41, and then the board body 41 can be directly assembled inside the housing 10. This allows the capacitor sections 42 to connect with the shielding assembly 20 and the copper busbar assembly 30 without increasing the original volume of the male terminal of the connector. By changing the capacitors that were originally installed in the electric vehicle control system to be installed inside the male terminal of the connector, internal space of the electric vehicle control system is saved, the number of parts is reduced, the installation steps are simplified, production costs are reduced, and production efficiency is improved.

[0038] Please see Figure 9 In conjunction with the above embodiments, in some embodiments, the circuit assembly 40 further includes a plurality of conductive parts 43, the conductive parts 43 and the capacitor parts 42 are connected to the same side of the plate 41, the elastic part 31 is connected to the first connection end 421 through at least one conductive part 43, and the first contact part 21 is connected to the second connection end 422 through at least one conductive part 43.

[0039] Understandably, the circuit assembly 40 also includes multiple conductive portions 43 connected to the board 41, and each capacitor portion 42 has its first connection terminal 421 and second connection terminal 422 electrically connected to a conductive portion 43. The conductive portion 43 has a copper foil structure and a large contact area, facilitating the connection of the elastic portion 31 and the first contact portion 21 to their respective conductive portions 43. The elastic portion 31 is electrically connected to the first connection terminal 421 of the capacitor portion 42 via the conductive portion 43, and the first contact portion 21 is electrically connected to the second connection terminal 422 via the conductive portion 43. The conductive portion 43 can be configured in various shapes and have multiple extension directions to adapt to the complex internal structure of the connector, facilitating the connection of the elastic portion 31 and the first contact portion 21 to their respective conductive portions 43.

[0040] Please see Figure 1 , Figure 2 and Figure 4 In conjunction with the above embodiments, in some embodiments, the housing 10 has a mounting groove 13 communicating with the receiving groove 11, and at least a portion of the copper busbar assembly 30 is embedded in the mounting groove 13. The housing 10 has a first annular groove 14, and the connector further includes a magnetic element 50, which is embedded in the first annular groove 14 and disposed around the copper busbar assembly 30.

[0041] Understandably, by Figure 4 As shown, a mounting groove 13 communicating with the receiving groove 11 is also provided on the housing 10. At least a portion of the copper busbar assembly 30 can be embedded in the mounting groove 13. The number of mounting grooves 13 is the same as the number of copper busbar assemblies 30. When there is one mounting groove 13, it can be provided on one side of the receiving groove 11. If there are multiple mounting grooves 13, the mounting grooves 13 can be provided on both sides of the receiving groove 11, or they can be arranged around the receiving groove 11. Figure 4 and Figure 10As shown, a first annular groove 14 is provided on the front side of the housing 10. The first annular groove 14 surrounds the receiving groove 11 and the mounting groove 13. A magnetic element 50 can be installed inside the first annular groove 14. The magnetic element 50 is a magnetic ring structure, and its shape can be adjusted according to the internal structure of the male end of the connector (if the internal structure of the male end cannot be changed, the magnetic element 50 may need to make way, resulting in a recessed avoidance groove on the magnetic element 50. A protrusion is formed at the position corresponding to the avoidance groove. A groove corresponding to the protrusion can be provided inside the first annular groove 14 so that the magnetic element 50 can cooperate with the groove during installation, thereby playing a positioning role in the installation of the magnetic element 50). After the magnetic element 50 is embedded in the first annular groove 14, it also surrounds the copper busbar assembly 30. This structure can make the magnetic element 50 miniaturized (compared to the magnetic ring installed in the electric vehicle control system), and can effectively suppress current surges and convert electromagnetic interference energy into heat dissipation, thereby reducing the intensity of electromagnetic interference.

[0042] After installing the capacitor 42 and the ring-shaped magnetic component 50 on the male terminal of the connector, and completing the assembly of the male terminal, the male and female terminals need to be connected. For example... Figure 4 , Figure 5 and Figure 6 As shown, a connection structure 90 is provided on the male end of the connector. The connection structure 90 can be integrally formed with the housing 10, serving as part of the housing 10. The number of connection structures 90 is set as needed (two are shown in the figure). A mounting hole 91 is provided inside the connection structure 90, extending from the front to the back of the housing 10. A signal terminal 92 is provided inside the mounting hole 91. When the male end of the connector is connected to the female end, the connection structure 90 on the male end connects with the corresponding structure on the female end, thereby connecting the signal terminal 92 on the male end with the corresponding terminal on the female end, allowing electrical signals to be conducted through the terminals.

[0043] Please see Figure 2 , Figure 5 , Figure 7 and Figure 13 In conjunction with the above embodiments, in some embodiments, the capacitor part 42 is disposed on the side of the plate 41 facing the bottom wall of the receiving groove 11, at least a portion of the elastic part 31 is located on the same side of the plate 41 as the capacitor part 42 and is connected to the first connecting end 421, and at least a portion of the first contact part 21 is located on the same side of the plate 41 as the capacitor part 42 and is connected to the second connecting end 422.

[0044] The connector also includes a limiting component 60, which is at least partially disposed on the side of the plate 41 away from the capacitor part 42 for fixing the plate 41. At least part of the limiting component 60 is disposed on the side of the magnetic part 50 away from the bottom wall of the mounting groove 13 for fixing the magnetic part 50.

[0045] It is understandable that, such as Figure 9 As shown, the conductive part 43 and the capacitor part 42 can be disposed on the same side of the plate 41, preferably on the side of the plate 41 facing the bottom wall of the receiving groove 11. Figure 5 As shown, since the through hole 12 is formed on the bottom wall of the receiving groove 11, the first contact portion 21 is embedded into the receiving groove 11 through the through hole 12. This is equivalent to the capacitor portion 42 being disposed on the side of the plate 41 facing the first contact portion 21, facilitating the connection of the first contact portion 21 to the second connection end 422 of the capacitor portion 42 via the conductive portion 43 located on the same side. Meanwhile, as... Figure 11 As shown, the elastic part 31 on the copper busbar assembly 30 can be embedded into the inside of the receiving groove 11 and connected to the first connection end 421 on the capacitor part 42. If it is inconvenient for the elastic part 31 to be connected to the first connection end 421, a part of it can be bent. This part can extend to the side of the plate 41 facing the capacitor part 42, so that it can be easily connected to the first connection end 421 of the capacitor part 42 through the conductive part 43 located on the same side.

[0046] like Figure 13 As shown, to ensure the secure connection between the capacitor part 42 and the first contact part 21 and the elastic part 31, the plate 41 can be pressed by the limiting component 60 to stably position it inside the receiving groove 11. A portion of the limiting component 60 is located on the side of the plate 41 opposite to the capacitor part 42, and presses and fixes the plate 41. Meanwhile, as... Figure 14 and Figure 15 As shown, a portion of the limiting component 60 is also disposed on the side of the magnetic component 50 away from the bottom wall of the mounting groove 13. This portion presses and fixes the magnetic component 50, giving the magnetic component 50 a certain degree of stability and preventing it from detaching from the interior of the mounting groove 13.

[0047] Please see Figure 2 , Figure 11 and Figure 13 As shown, in conjunction with the above embodiments, in some embodiments, the limiting component 60 includes a pressure plate portion 61 and a fixing portion 62.

[0048] The pressure plate portion 61 is located on the side of the plate body 41 away from the capacitor portion 42 and is connected to the plate body 41. The fixing portion 62 passes through the pressure plate portion 61 and the plate body 41 and is detachably connected to the housing 10. The fixing portion 62 is used to connect the pressure plate portion 61, the plate body 41 and the housing 10.

[0049] It is understandable that, such as Figure 13 As shown, the plate 41 is placed inside the receiving groove 11. The capacitor part 42 and the conductive part 43 are placed on the side of the plate 41 facing the bottom wall of the receiving groove 11, and the pressure plate part 61 is placed on the side of the plate 41 away from the bottom wall of the receiving groove 11. This arrangement ensures that the pressure plate part 61 and the capacitor part 42 are located on opposite sides of the plate 41. When the pressure plate part 61 presses the plate 41, it will not affect the capacitor part 42 and the conductive part 43. The surface of the pressure plate part 61 facing the plate 41 and the surface of the plate 41 facing the pressure plate part 61 can be made flat, with the two flat surfaces abutting each other. When the pressure plate part 61 presses the plate 41, the force on the plate 41 can be more even, preventing damage to other structures. One end of the fixing part 62 on the limiting component 60 can pass through the pressure plate part 61 and the plate body 41 and be connected to the housing 10. The fixing part 62 can be a screw structure, with one end passing through the pressure plate part 61 and the plate body 41 and then threadedly connected to the housing 10. The pressing force of the other end of the fixing part 62 on the pressure plate part 61 can be controlled by the action of the thread, thereby controlling the pressing force of the pressure plate part 61 on the plate body 41, ensuring the stability of the plate body 41 inside the receiving groove 11, and also preventing some structures from being crushed.

[0050] Please see Figure 9 , Figure 11 and Figure 12 In conjunction with the above embodiments, in some embodiments, the plate 41 has a first positioning groove 411, and the limiting component 60 further includes a first positioning part 63. The first positioning part 63 is connected to the side of the pressure plate part 61 facing the plate 41 and is embedded in the first positioning groove 411.

[0051] Understandably, multiple first positioning grooves 411 are provided on the plate body 41, and multiple first positioning parts 63 are provided on the limiting component 60. The number of first positioning parts 63 is the same as the number of first positioning grooves 411, and their positions correspond one-to-one. The first positioning parts 63 can be connected to the pressure plate part 61. When the pressure plate part 61 is connected to the plate body 41, the first positioning parts 63 can pass through the corresponding first positioning grooves 411, thus positioning the connection between the pressure plate part 61 and the plate body 41. Simultaneously, a locking structure is provided inside the first positioning part 63. The locking structure engages with the plate body 41, providing a certain degree of limitation for the plate body 41, ensuring the connection between the pressure plate part 61 and the plate body 41 is stable.

[0052] Please see Figure 12 , Figure 14 and Figure 15In conjunction with the above embodiments, in some embodiments, the limiting component 60 further includes an extension 64. The extension 64 is connected to the pressure plate portion 61, and at least a portion of the extension 64 is disposed on the side of the magnetic element 50 away from the bottom wall of the mounting groove 13 and is connected to the magnetic element 50.

[0053] It is understood that the limiting component 60 is also provided with an extension 64, which is connected to the outer peripheral edge of the pressure plate portion 61. The number and distribution of the extension 64 can be set as needed, such as multiple extensions arranged around the pressure plate portion 61. At least a portion of the extension 64 is provided on the side of the magnetic component 50 away from the bottom wall of the mounting groove 13 and abuts against the magnetic component 50, which can stably position the magnetic component 50 inside the mounting groove 13 and prevent it from falling out of the mounting groove 13 due to external forces.

[0054] Alternatively, the magnetic component 50 can be limited by other structures, such as by pressing the magnetic component 50 with a fixing ring that is similar in shape to the magnetic component 50 to ensure the stability of the magnetic component 50. The fixing ring is connected to the housing 10 by a snap-fit ​​structure for easy assembly and disassembly.

[0055] Please see Figure 11 , Figure 12 and Figure 14 In conjunction with the above embodiments, in some embodiments, the extension 64 has a second positioning groove 641, and the housing 10 includes a second positioning part 15, which passes through the second positioning groove 641.

[0056] It is understood that a second positioning groove 641 can be provided on the extension 64, or the extension 64 can be enclosed with the pressure plate 61 to form a second positioning groove 641. A second positioning part 15 can be provided on the housing 10. The second positioning part 15 can be provided inside the receiving groove 11 or outside the receiving groove 11. The number of second positioning parts 15 is the same as the number of second positioning grooves 641, and their positions correspond one-to-one. When installing the limiting component 60, the second positioning part 15 can pass through the corresponding second positioning groove 641 on the limiting component 60, which plays a certain positioning role in the installation of the pressure plate 61 and ensures its stability during the installation process.

[0057] Please see Figure 2 , Figure 4 and Figure 5 In conjunction with the above embodiments, in some embodiments, the housing 10 has a second annular groove 16. The connector includes a seal 70 disposed within the second annular groove 16 and surrounding the magnetic element 50.

[0058] It is understood that a second annular groove 16 can be provided on the front side of the housing 10, and the second annular groove 16 is located on the outer periphery of the first annular groove 14. The connector is also provided with a seal 70, which is embedded inside the second annular groove 16, when the housing 10 and the cover plate 80 are connected (e.g., ...). Figure 1 and Figure 2 As shown, the sealing performance of the connection between the housing 10 and the cover plate 80 can be improved by the seal 70, preventing water stains or impurities from entering the interior of the receiving groove 11 from between the housing 10 and the cover plate 80. The seal 70 can be made of rubber.
