[0002] With the increasing demand for energy conservation, emission reduction, and air pollution control, new energy vehicles are gradually being widely used in the market, with electric vehicles being the mainstay. Among these, the on-board charger (OBC) signal socket plays a crucial communication role in the overall operation of the device.

[0003] In existing on-board charger layouts, the signal socket cannot be completely isolated from other components. Because filters, copper busbars, output terminals, and other devices are located near the signal socket, it is susceptible to electromagnetic interference from these components during command transmission and reception. This interference can cause inaccurate signal transmission, leading to errors during on-board charger operation.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] In view of this, the present invention provides a signal socket that can prevent the signal socket from being affected by electromagnetic interference from other nearby components, thereby ensuring that the operation of the signal socket is not disturbed and that the charger works normally.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A signal socket for use in a charger includes: a housing and a signal board assembly and a main power board mounted on the housing. The housing is provided with a shielding structure for accommodating electromagnetically sensitive devices of the signal board assembly. The signal socket also includes a shielding component.

[0008] The shielding component is installed on the signal board assembly and is used to cover the electromagnetically sensitive device together with the shielding structure of the housing.

[0014] The inductor is placed inside the shielding cavity.

[0015] Preferably, the shielding assembly includes a shielding cover.

[0016] Preferably, it also includes a face cover;

[0017] The faceplate is mounted on the housing and is used to cover the signal board and the main power board;

[0018] The shielding assembly also includes connectors;

[0019] The connector is mounted on the shield and is used to contact the faceplate.

[0020] Preferably, the shielding cover has two through slots;

[0021] The connector includes a spring clip;

[0022] The two ends of the spring are snapped into the two slots of the shielding cover, and the middle part is arched to make elastic contact with the face cover.

[0023] Preferably, the first portion of the signal terminal of the signal board assembly is mounted on the support frame of the housing;

[0024] The signal socket also includes a sealing ring;

[0025] The sealing ring is fitted onto the first part of the signal terminal, and both sides of its top are provided with extensions. The two extensions of the sealing ring are installed on both sides of the support frame.

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] The signal socket provided in this embodiment of the utility model is applied to a charger, such as... Figure 1 and Figure 2 As shown, it includes: a housing 1 and a signal board assembly and a main power board 3 mounted on the housing 1. The housing 1 is provided with a shielding structure for accommodating electromagnetic sensitive devices of the signal board assembly. The signal socket also includes a shielding component.

[0046] The shielding assembly is installed on the signal board assembly and is used to cover the electromagnetically sensitive device within the shielding structure of the same housing 1.

[0047] It should be noted that the electromagnetic sensitive devices in the signal board assembly can be functional devices within the signal board assembly that are susceptible to electromagnetic signal influence or interference, such as the inductors in signal board 10; of course, such as Figure 4 As shown, the signal board assembly includes: a signal board 10 and signal terminals 11 mounted on the signal board 10, such as... Figure 7 As shown, the inductor can be located at the bottom of the signal board 10, and the inductor can be a signal inductor 14;

[0048] When the signal board assembly is mounted on the housing 1, the electromagnetic sensitive device of the signal board assembly can be accommodated or placed in the shielding structure of the housing 1. The shielding structure of the housing 1 can surround the electromagnetic sensitive device on all sides and below, thus satisfying the high-frequency signal isolation. Of course, considering that the electromagnetic sensitive device is set on the signal board assembly, the shielding structure of the housing 1 is difficult to fully surround the electromagnetic sensitive device, so it can form a partial surround as described above.

[0049] The shielding component can be a shielding cover assembly, which can be installed on the signal board assembly and distributed correspondingly with the shielding structure of the housing 1. The combination of the shielding cover assembly and the shielding structure of the housing 1 forms a complete enclosed shield for the electromagnetically sensitive device. This effectively shields the electromagnetically sensitive device of the signal board assembly, preventing electromagnetic interference from nearby components and isolating it from external electromagnetic signal interference. This ensures accurate transmission of signal commands from the signal socket and guarantees the normal operation of the charger. Of course, the shielding component and the shielding structure of the housing 1 are only used to shield the electromagnetically sensitive device of the signal board assembly from electromagnetic interference from other components; they do not affect the normal operation of the electromagnetically sensitive device. Furthermore, the shielding structure of the housing 1 will not interfere with other structures of the housing 1 or other components of the signal board assembly. Moreover, the charger can be an on-board charger or a charger for other applications.

[0050] In other words, the signal socket provided by this solution, through the shielding structure of the housing 1, is used to accommodate the electromagnetic sensitive devices of the signal board assembly, which facilitates the formation of a partial surrounding shield for the electromagnetic sensitive devices. Furthermore, through the addition of shielding components, the remaining parts of the electromagnetic sensitive devices are also surrounded. That is, through the combined use of the shielding structure of the housing 1 and the shielding components, a fully surrounding shield can be formed for the electromagnetic sensitive devices. This can prevent the signal socket from being affected by electromagnetic interference from other nearby components, thereby ensuring that the operation of the signal socket is not interfered with and guaranteeing the normal operation of the charger.

[0051] In this scheme, the electromagnetic sensing device includes an inductor;

[0052] like Figure 7 As shown, the inductor is located at the bottom of the signal board 10 of the signal board assembly;

[0053] The shielding structure of the housing 1 is located below the signal board 10;

[0054] The shielding components are mounted on the signal board 10 and are distributed in a manner corresponding to the shielding structure of the housing 1.

[0055] It should be noted that, as mentioned above, the electromagnetic sensing device can be an inductor of the signal board 10, and the inductor is located at the bottom of the signal board 10, that is, below the signal board 10; wherein, such as Figure 7 As shown, the inductor can be a signal inductor 14;

[0056] To facilitate the housing or placement of the inductors of the signal board 10 within the shielding structure of the housing 1, the shielding structure of the housing 1 is located below the signal board 10. The top of the shielding structure is open to facilitate the insertion of the inductors. After the inductors are inserted into the shielding structure of the housing 1, the shielding structure of the housing 1 can surround the inductors on all sides and below, thus providing semi-enclosed shielding. The shielding structure of the housing 1 can be a shielding ring or a shielding box with an open top. The specific configuration of the shielding structure of the housing 1 can be determined based on the orientation of the electromagnetically sensitive device.

[0057] The shielding assembly can be installed on the signal board 10 and is distributed vertically in correspondence with the shielding structure of the housing 1. This can form a surrounding of the inductor above, and further cover the inductor around and on the top and bottom, thus forming a fully enclosed shield for the inductor.

[0058] In other words, the shielding structure of the shielding components and housing 1 is arranged in such a way that it is easy to form a full-enclosed shield around the inductors of the signal board 10 and on the top and bottom sides, so that the inductors of the signal board 10 can obtain a better shielding effect; of course, the shielding structure of the shielding components and housing 1 can be arranged according to the orientation of the electromagnetic sensitive device.

[0059] Specifically, such as Figure 3 As shown, the shielding structure of the housing 1 includes: a shielding box 15 disposed on the housing 1, the top of the shielding box 15 being an open structure, and a shielding cavity 16 being formed between its inner wall and the housing 1.

[0060] The inductor is placed inside the shielding cavity 16.

[0061] It should be noted that, as Figure 3 As shown, the shielding structure of the housing 1 can be a shielding box 15 disposed on the bottom plate of the housing 1. The top of the shielding box 15 is an open structure, and a shielding cavity 16 is formed between the inner peripheral wall of the shielding box 15 and the bottom plate of the housing 1, thus forming a shielding cavity 16 with an open top. In this way, after the inductor is placed, it can surround the inductor on all sides and the bottom. Of course, the shielding cavity 16 can be used to accommodate or place the inductor, thus providing a better EMC shielding effect for the inductor and meeting the requirements of high-frequency signal isolation. In addition, when the signal board assembly is mounted on the housing 1, the inductor of the signal board 10 is located in the shielding cavity 16 of the housing 1 to surround the inductor on all sides and the bottom. Moreover, the shielding assembly can be a shielding cover assembly, which is distributed correspondingly to the top port of the shielding box 15, so that the shielding cover assembly is equivalent to the cover or lid of the shielding box 15, thus surrounding the upper side of the inductor. Of course, if Figure 3As shown, the support bracket 18 on the housing 1 for mounting the signal terminal 11 can be used as one side wall of the shielding box 15. In this way, when the signal board assembly is mounted on the housing 1, it is convenient to install the signal terminal 11 and also convenient to directly install the inductor into the shielding cavity 16.

[0062] In other words, such as Figure 3 As shown, the shielding structure of the housing 1 is designed as a shielding box 15, which not only facilitates the installation of inductor devices, but also forms a so-called semi-enclosed shield around and below the inductor devices.

[0063] Furthermore, such as Figure 2 As shown, the shielding assembly includes a shielding cover 9.

[0064] The shielding cover 9 can be screwed onto the first part of the top surface of the signal board 10. The first part of the top surface of the signal board 10 corresponds to the top port of the shielding box 15, thus allowing the shielding cover 9 to form a spaced seal over the top port of the shielding box 15, thereby providing better full-enclosure shielding for the inductor. In other words, the combined use of the shielding cover 9 and the shielding box 15 facilitates the construction of a shielded cavity structure to enclose the inductor, effectively isolating it from external electromagnetic interference.

[0065] Furthermore, such as Figure 2 As shown, the signal socket provided in this embodiment of the present invention also includes a faceplate 6;

[0066] like Figure 1 As shown, the faceplate 6 is mounted on the housing 1 and is used to cover the signal board 10 and the main power board 3;

[0067] The shielding assembly also includes connectors;

[0068] The connector is mounted on the shield 9 and is used to contact the faceplate 6.

[0069] In other words, on the one hand, by providing a face cover 6 on the housing 1, the signal board 10 and the main power board 3 can be prevented from being exposed, ensuring the appearance of the signal socket; on the other hand, by providing a connector between the shielding cover 9 and the face cover 6, the grounding resistance of the shielding cover 9 can be reduced, which also makes it easier to increase the grounding effect of the shielding cover 9, thereby enhancing the shielding effect of the shielding cover 9; of course, the connector can be used for elastic or rigid contact with the face cover 6.

[0070] In this plan, such as Figure 10 As shown, the shielding cover 9 has two through slots 17;

[0071] like Figure 2 As shown, the connector includes a spring piece 13;

[0072] like Figure 9As shown, the two ends of the spring piece 13 are snapped into the two slots 17 of the shielding cover 9, and the middle part is arched and used for elastic contact with the face cover 6.

[0073] It should be noted that, in order to increase the contact area between the spring 13 and the faceplate 6, and thus further enhance the grounding effect of the shielding cover 9, the spring 13 can be adopted as follows: Figure 10 The structure shown includes a spring piece 13 with multiple sets of snap-fit ​​tabs along its length, each set including two bent snap-fit ​​tabs, and the middle portion of the spring piece 13 arches upward to facilitate elastic contact with the faceplate 6; correspondingly, the shielding cover 9 has multiple sets of slots 17, which can be distributed in parallel along the length of the shielding cover 9, each set including two oppositely distributed slots 17; the multiple sets of snap-fit ​​tabs of the spring piece 13 snap into the multiple sets of slots 17, and the two snap-fit ​​tabs in each set snap into each other. One piece is inserted into the corresponding two slots 17 and hooks onto the lower end face of each slot, thereby securing the set of snap-fit ​​pieces in the corresponding slots 17. Of course, at this time, the middle part of the spring piece 13 between each set of snap-fit ​​pieces is in elastic contact with the cover 6. Moreover, the spring piece 13 adopts this snap-fit ​​method, which can facilitate the installation of the spring piece 13 on the shielding cover 9, and also allows the middle part of the spring piece 13 to have good elasticity to contact the cover 6, thus allowing the spring piece 13 to be clamped between the shielding cover 9 and the cover 6.

[0074] In other words, the aforementioned spring piece 13 is an elastic connector, which can not only be easily installed on the shielding cover 9, but also easily form elastic contact with the face cover 6, thus enabling a soft connection between the shielding cover 9 and the face cover 6, thereby meeting the overall vibration requirements of the charger.

[0075] Specifically, such as Figure 5 As shown, the first part of the signal terminal 11 of the signal board assembly is mounted on the support bracket 18 of the housing 1;

[0076] Furthermore, because the signal terminals of the signal socket have an irregular structure, ordinary flat sealing methods cannot effectively seal them, posing a risk of seal failure and water ingress. This prevents the signal terminals of the signal socket from meeting the required waterproof rating. Therefore, if... Figure 2 As shown, the signal socket also includes a sealing ring 12;

[0077] like Figure 5 As shown, the sealing ring 12 is fitted onto the first part of the signal terminal 11, and both sides of its top are provided with extensions 19. The two extensions 19 of the sealing ring 12 are installed on both sides of the support bracket 18.

[0078] The bottom and two sides of the sealing ring 12 abut against the support frame 18, and the top of the sealing ring 12 and the tops of the two extensions 19 abut against the cover 6.

[0079] It should be noted that, as Figure 2 As shown, the first part of the signal terminal 11 is the trapezoidal part of the signal terminal 11; the structure of the support frame 18 of the housing 1 is as follows: Figure 3 As shown, it has a support groove for adapting and supporting the first part of the signal terminal 11; as Figure 2 As shown, the sealing ring 12 can be a trapezoidal sealing ring, and can be adapted to be installed on the first part of the signal terminal 11. The two extensions 19 at the top of the sealing ring 12 can overlap the two sides of the support bracket 18, and the bottom and two sides of the sealing ring 12 abut against the support groove of the support bracket 18, while the top of the sealing ring 12 and the tops of the two extensions 19 abut against the faceplate 6. In this way, the bottom and two sides of the sealing ring 12 abut (install) between the signal terminal 11 and the support groove of the support bracket 18, and the top of the sealing ring 12 abuts against the signal terminal 11. The connection between the signal terminal 11 and the cover 6, and the abutment of the two extensions 19 against the sides of the support frame 18 and the cover 6, can form a seal between any two of the support frame 18, the signal terminal 11, and the cover 6. This creates a sealing system for the support frame 18, the signal terminal 11, and the cover 6 of the housing 1, thereby effectively sealing the signal terminal of the signal socket. This ensures the airtightness of the signal terminal structure and guarantees that the signal terminal meets the corresponding waterproof rating, such as IP67.

[0080] Furthermore, such as Figure 2 As shown, the top of the first part of the signal terminal 11 is provided with a first mounting groove 20, which is used to mount the top of the sealing ring 12;

[0081] And / or, such as Figure 3 As shown, the support bracket 18 has a second mounting groove 21 on both sides, which is used to install the two extensions 19 of the sealing ring 12.

[0082] Among them, such as Figure 2 As shown, the first mounting groove 20 can also be a first limiting groove, that is, used to install and limit the top of the sealing ring 12; similarly, as Figure 3 As shown, the second mounting groove 21 can also be a second limiting groove, that is, used to install and limit the extension 19 of the corresponding sealing ring 12; of course, the top of the sealing ring 12 needs to protrude out of the first mounting groove 20 after installation, and the extension 19 of the sealing ring 12 is also designed in the same way, so that the top of the sealing ring 12 and the top of the two extensions 19 can respectively abut against the bottom surface of the cover 6.

[0083] In other words, the top of the first part of the signal terminal 11 is provided with a mounting structure for engaging with the top of the sealing ring 12, and each side of the support bracket 18 is provided with a mounting structure for engaging with the corresponding extension 19 of the sealing ring 12. This facilitates the quick installation of the sealing ring 12 and its two extensions 19, and also enables a tight sealing effect between the support bracket 18 and the cover 6, and between the signal terminal 11 and the cover 6.

[0084] Furthermore, there is a height difference between the main power board and the signal board of the signal socket. If ordinary wiring harnesses are used for connection, there is a risk of vibration failure, which could lead to inaccurate signal transmission and cause errors in the on-board charger during operation. Therefore, furthermore, such as Figure 8 As shown, the main power board 3 and the signal board 10 are connected by pin header 2.

[0085] It should be noted that the structure of pin header 2 is as follows: Figure 2 As shown; correspondingly, both the main power board 3 and the signal board 10 have pin header mounting holes. After the lower end of the pin header 2 is installed in the pin header mounting hole of the main power board 3, it can be fixed there by soldering. After the upper end is installed in the pin header mounting hole of the signal board 10, it can be fixed there by soldering. That is to say, the pin header 2 can be connected between the main power board 3 and the signal board 10 by soldering, which helps to eliminate installation stress and ensure the reliability of signal transmission.

[0086] In addition, it should be noted that, such as Figure 2 As shown, this signal socket comprises: housing 1, pin header 2 (i.e., connecting pin header), main power board 3, main power screw 4, signal board screw 5, faceplate 6, faceplate screw 7, shielding cover screw 8, shielding cover 9, signal board 10, signal terminal 11, and sealing ring 12. Furthermore, to better understand this signal socket, the assembly process of its structural components is explained below:

[0087] First, solder the pin header 2 onto the main power board 3. Then, install the main power board 3 onto the housing 1. Finally, use the main power board screws 4 to tighten the housing 1 and the main power board 3, thus assembling the main power board assembly. Figure 3 As shown;

[0088] First, solder the signal terminal 11 onto the signal board 10. Then, fit the sealing ring 12 onto the sealing portion of the signal terminal 11 (i.e., the first part of the signal terminal 11) to form the signal board assembly. Figure 4 As shown;

[0089] The assembled signal board assembly is then installed onto the main power board assembly. The housing's cavity design (i.e., shielding box) provides excellent EMC shielding. The inductors on the signal board can be placed within the shielding cavity of the housing, meeting high-frequency signal isolation requirements. Furthermore, soldering the main power board and signal board using pin headers eliminates installation stress, ensuring reliable signal transmission. The ring-shaped sealing ring design effectively guarantees the airtightness of this component, meeting IP67 testing requirements. Figure 5 As shown;

[0090] The shielding spring (i.e., spring 14) is installed on the shielding cover 9 to form a shielding cover assembly (i.e., a shielding component). Because this installation method is quick-installation, it has good installation processability, excellent vibration resistance, and can reduce the grounding resistance of the shielding cover, thus enhancing the shielding effect of the structure. Figure 10 As shown;

[0091] Next, install the shielding cover 9 onto the signal board 10, and tighten the shielding cover 9, signal board 10, and housing 1 with the shielding cover screws 8; wherein, the four corners of the shielding cover are grounded to the housing through the tightening screws, which can effectively form a shielding cavity with the housing to isolate external electromagnetic signal interference, such as Figure 6 As shown;

[0092] Next, install the faceplate 6 onto the housing 1, and tighten the faceplate 6 and housing 1 with the faceplate screws 7 to meet the airtightness requirements of the overall cavity. Figure 1 As shown;

[0093] like Figure 7 As shown, the sealing ring 12 surrounds the signal terminal 11, forming a sealing system of the housing 1, signal terminal 11, and face cover 6; the signal inductor 16 on the signal board is enclosed by the cavity of the metal housing, forming a good shielding cavity below the signal board, and the metal shielding cover 9 is fastened above. The shielding spring contacts the face cover 6 to increase the contact area and reduce the grounding resistance of the shielding cover 9, thus forming the shielding structure of the entire signal board.

[0094] like Figure 8 As shown, the upper and lower signal boards and main power boards are connected by connector pins. Since the upper and lower boards are first fastened with screws and then the connector pins are soldered, the welding stress can be eliminated.

[0095] The shielding spring contacts of shielding cover 9 enhance the grounding effect of the shielding cover, achieving a soft connection between shielding cover 9 and faceplate 6, matching the vibration requirements of the entire machine, and protecting the shielding cover and PCB board, such as... Figure 9 As shown.

[0096] This utility model embodiment also provides a charger, including a signal socket, which is the signal socket described above. Since this solution uses the aforementioned signal socket, it has corresponding beneficial effects, as detailed in the preceding description, which will not be repeated here.
