[0002] In some electrical devices, to meet user needs, incompatible or non-simultaneous circuit interfaces may be placed adjacent to each other. However, in actual use, only one of these two circuit interfaces can be used. For example, in a PPS (portable power station), to ensure overall aesthetics and ease of use, the panel typically includes several USB (Universal Serial Bus) power interfaces and several photovoltaic input interfaces. To conserve panel space, the photovoltaic input and power interfaces are placed very close together. However, using both interfaces simultaneously presents certain circuit safety risks.

[0006] In an optional embodiment, the anti-misinsertion cover includes a shielding portion and a sliding portion that are interconnected, and the sliding portion is used to drive the shielding portion to slide along a first direction to switch the position of the anti-misinsertion cover so that the shielding portion shields the first circuit interface or the second circuit interface; wherein the first direction is the arrangement direction of the first circuit interface and the second circuit interface.

[0011] In an optional embodiment, at least one first contact bone position is provided on a side of the sliding portion facing the control panel, the first contact bone position abuts against a side of the control panel facing the fixed bracket, and the portion of the control panel abutting against the first contact bone position is set as a smooth surface.

[0012] In an optional embodiment, the anti-misinsertion structure includes an anti-mistake structure, which includes an anti-mistake column and an anti-mistake groove that cooperate with each other, one of the anti-mistake column and the anti-mistake groove is arranged on a side of the sliding part facing the control panel, and the other of the anti-mistake column and the anti-mistake groove is arranged on a side of the control panel facing the fixed bracket.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0033] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside", "outside", "inside", "outside", "below", "beneath", "above", "above", "front", "back", etc. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a position flip or a change in posture or a change in movement state, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device can be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0034] In today's era of rapid technological advancement, a wide variety of electrical devices are emerging, greatly enriching and facilitating people's lives. To meet users' needs for simultaneous use of multiple appliances and improve efficiency, multiple circuit interfaces are often centrally located on electrical devices or outlet panels. However, while this design brings convenience, it also raises a significant issue. Due to differences in technical standards and functional requirements, these adjacent circuit interfaces may be different types of interfaces that cannot be used simultaneously. In daily use, especially when users are in a hurry or not paying attention, it is easy to plug two external plug connectors into two circuit interfaces that cannot be used simultaneously. This mistake not only prevents a proper electrical connection but can also cause serious damage to the circuit interfaces and the circuits they connect to, affecting the normal operation of the electrical device and even posing a safety hazard.

[0035] The present disclosure provides an anti-misinsertion structure and an electrical device, which can prevent two adjacent incompatible circuit interfaces from being easily misinserted and used at the same time. In the anti-misinsertion structure of the electrical device disclosed in the present disclosure, the first circuit interface and the second circuit interface can be selectively shielded by the anti-misinsertion cover. That is, when the first circuit interface needs to be used, the anti-misinsertion cover can be moved to a position that shields the second circuit interface to expose the first circuit interface. In this case, when the relevant personnel use the first circuit interface, since the second circuit interface is shielded by the anti-misinsertion cover, it will not be mistakenly inserted into the second circuit interface again, which can avoid the two circuit interfaces being inserted at the same time, and the second circuit interface can be dust-proofed; when the second circuit interface needs to be used, the anti-misinsertion cover can be moved to a position that shields the first circuit interface to expose the second circuit interface. In this case, when the relevant personnel use the second circuit interface, since the first circuit interface is shielded by the anti-misinsertion cover, it will not be mistakenly inserted into the first circuit interface again, which can avoid the two circuit interfaces being inserted and used at the same time, and the first circuit interface in an unused state can be dust-proofed. The solution disclosed herein can prevent the mis-insertion of two mutually incompatible but adjacent circuit interfaces, while also providing dust protection for unused circuit interfaces. The solution disclosed herein eliminates the need to locate the two circuit interfaces on different sides of an electrical device, thereby avoiding the dispersion of functional interfaces within the electrical device, ensuring the overall aesthetics of the electrical device and enhancing the user experience. Furthermore, because the solution addresses the mis-insertion prevention issue for two adjacent circuit interfaces, it can prevent users from becoming entangled with external plug-in cables.

[0036] refer to Figures 1 to 3 As shown, in an exemplary embodiment, an electrical device and an anti-misinsertion structure 50 thereof are provided. The electrical device may include a first circuit interface 10 and a second circuit interface 20 that are incompatible with each other, that is, the circuit corresponding to the first circuit interface 10 in the electrical device and the circuit corresponding to the second circuit interface 20 in the electrical device are incompatible circuits, and the two cannot be used at the same time, and only one of them can be used.

[0037] The electrical device may be an energy storage power supply. For example, the energy storage power supply includes a first circuit interface and a second circuit interface that cannot be plugged in and used simultaneously. The first circuit interface 10 may be a universal serial bus interface (USB interface) in a portable power station (PPS) device, and the second circuit interface 20 may be a photovoltaic charging interface (e.g., an XT60 photovoltaic charging interface) in a PPS device.

[0038] It should be noted that the electrical device can be other devices besides the charging device mentioned above, and this is not limited to this. The first circuit interface 10 and the second circuit interface 20 can be other incompatible circuit interfaces besides the USB interface and photovoltaic charging interface mentioned above, and this is not limited to this.

[0039] It is understood that two incompatible interfaces are generally those that cannot directly cooperate, connect, or interact with each other. This may be due to a variety of reasons, such as differences in interface specifications, parameters, data formats, communication protocols, electrical characteristics, etc.

[0040] The mutual incompatibility of this embodiment means that the two circuit interfaces cannot be used at the same time. For example, for a USB interface and a photovoltaic charging interface, when using the USB interface, it is necessary to use the first part of the circuit in the electrical device, and the first part of the circuit is the circuit corresponding to the USB interface; when using the photovoltaic charging interface, it is necessary to use the second part of the circuit in the electrical device, and the second part of the circuit is the circuit corresponding to the photovoltaic charging interface. The above-mentioned first part of the circuit and the second part of the circuit may have partially identical circuits, and the partially identical circuits cannot simultaneously meet the functions of the USB interface and the functions of the photovoltaic charging interface, that is, the first part of the circuit and the second part of the circuit are compatible with each other, which may lead to the mutual incompatibility of the USB interface and the photovoltaic charging interface, that is, the two cannot be used at the same time.

[0041] In this embodiment, an anti-misinsertion structure 50 may be provided in the electrical device. The anti-misinsertion structure 50 may include an anti-misinsertion cover 51, and the anti-misinsertion cover 51 has a first position and a second position. When the anti-misinsertion cover 51 moves to the first position, the anti-misinsertion cover 51 blocks the first circuit interface 10 to expose the second circuit interface 20. In this case, relevant personnel can use the second circuit interface 20 without inserting it into the first circuit interface 10 by mistake, and the first circuit interface 10 can be protected from dust. When the anti-misinsertion cover 51 moves to the second position, the anti-misinsertion cover 51 blocks the second circuit interface 20 to expose the first circuit interface 10. In this case, relevant personnel can use the first circuit interface 10 without inserting it into the second circuit interface 20 by mistake, and the second circuit interface 20 can be protected from dust.

[0042] The anti-misinsertion structure 50 may be a sliding structure, a rotating structure, or other adjustable structures, which is not limited thereto.

[0043] For example, the anti-misinsertion structure 50 can be a sliding structure, and the anti-misinsertion cover 51 of the anti-misinsertion structure 50 can be slidably connected to the body of the electrical device. When the anti-misinsertion cover 51 slides to a first position, the anti-misinsertion cover 51 can cover the first circuit interface 10 and expose the second circuit interface 20. When the anti-misinsertion cover 51 slides to a second position, the anti-misinsertion cover 51 can cover the second circuit interface 20 and expose the first circuit interface 10.

[0044] For another example, the anti-misinsertion structure 50 can be a rotating structure, and the anti-misinsertion cover 51 of the anti-misinsertion structure 50 can be rotatably connected to the body of the electrical device. When the anti-misinsertion cover 51 is rotated to a first position, the anti-misinsertion cover 51 can cover the first circuit interface 10 and expose the second circuit interface 20. When the anti-misinsertion cover 51 is rotated to a second position, the anti-misinsertion cover 51 can cover the second circuit interface 20 and expose the first circuit interface 10.

[0045] The electrical device of this embodiment and its anti-misinsertion structure 50 can not only prevent the misinsertion of two incompatible circuit interfaces (it should be noted that the anti-misinsertion in this embodiment means that when any one of the first circuit interface and the second circuit interface is in use, relevant personnel can be prevented from using the other circuit interface at the same time), but also can provide dust protection for the circuit interface that is not in use. Moreover, there is no need to set the two circuit interfaces on different surfaces of the electrical device, which can avoid the dispersion of functional interfaces in the electrical device, ensure the overall aesthetics of the electrical device, and enhance the user experience.

[0046] refer to Figures 1 to 7 As shown, in an exemplary embodiment, an anti-misinsertion structure 50 is provided. In this embodiment, an anti-misinsertion cover 51 can be slidably connected to the body of the electrical device.

[0047] Among them, reference Figure 1 、 Figure 3 and Figure 6 As shown, the anti-incorrect insertion cover 51 may include a shielding portion 511 and a sliding portion 512 connected to each other. The sliding portion 512 is used to drive the shielding portion 511 to slide along a first direction to switch the state of the anti-incorrect insertion cover 51 so that the shielding portion 511 blocks the first circuit interface 10 or the second circuit interface 20. The first direction is the arrangement direction of the first circuit interface 10 and the second circuit interface 20. For example, when the first circuit interface 10 and the second circuit interface 20 are arranged vertically, the first direction is vertical, and the sliding portion 512 can slide vertically, thereby switching the state of the anti-incorrect insertion cover 51 and adjusting the circuit interface blocked by the shielding portion 511. For another example, when the first circuit interface 10 and the second circuit interface 20 are arranged horizontally, the first direction is horizontal, and the sliding portion 512 can slide horizontally, thereby switching the state of the anti-incorrect insertion cover 51 and adjusting the circuit interface blocked by the shielding portion 511.

[0048] refer to Figure 1 、 Figure 3 and Figure 6As shown, when the sliding portion 512 drives the shielding portion 511 to slide to the position corresponding to the first circuit interface 10 along the first direction, the anti-misinsertion cover 51 is in the first position, and the shielding portion 511 of the anti-misinsertion cover 51 shields the first circuit interface 10, while the second circuit interface 20 is in an exposed state. In this case, relevant personnel can use the second circuit interface 20 without accidentally inserting it into the first circuit interface 10, and dust and other debris can be prevented from entering the first circuit interface 10, which can well protect the first circuit interface 10.

[0049] refer to Figure 2 、 Figure 3 and Figure 6 As shown, when the sliding portion 512 drives the shielding portion 511 to slide to the position corresponding to the second circuit interface 20 along the first direction, the anti-misinsertion cover 51 is in the second position, and the shielding portion 511 of the anti-misinsertion cover 51 shields the second circuit interface 20, while the first circuit structure is in an exposed state. In this case, relevant personnel can use the first circuit interface 10 without accidentally inserting it into the second circuit interface 20, and dust and other debris can be prevented from entering the second circuit interface 20, which can well protect the second circuit interface 20.

[0050] Among them, reference Figures 1 to 3 As shown, the electrical device may include a control panel 30 and a circuit board 40 (PCB). The PCB 40 may be provided with multiple circuit interfaces, such as the first circuit interface 10 and the second circuit interface 20 described above. The PCB 40 may be fixedly connected to the control panel 30, and the circuit interfaces on the PCB 40 may be exposed through a notch in the control panel 30 for use by relevant personnel.

[0051] It should be noted that in the related art, when the first circuit interface 10 and the second circuit interface 20 are respectively arranged on different surfaces, since the circuit interfaces need to cooperate with the control panel 30, and the two circuit interfaces are arranged on different surfaces, different circuit boards 40 and connecting wiring harnesses are required, which increases the overall cost of the electrical device. In this embodiment, the first circuit interface 10 and the second circuit interface 20 can be arranged on the same surface, with the two circuit interfaces facing the same direction and being arranged on the same surface of the same circuit board 40, which can reduce costs to a certain extent and also reduce the problem of electromagnetic interference radiation caused by cross-line connections.

[0052] Among them, reference Figure 1 、 Figure 3 、 Figure 6 and Figure 7As shown, when the electrical device includes a control panel 30, the anti-misinsertion structure 50 may include a fixed bracket 52 that cooperates with the sliding portion 512, and the fixed bracket 52 is fixedly connected to the control panel 30. For example, the fixed bracket 52 can be fixed to the control panel 30 by fasteners (such as screws or screws, etc.). The sliding portion 512 is placed between the control panel 30 and the fixed bracket 52. It should be noted that, in this embodiment, the side facing the circuit interface is the front side, and the side facing away from the circuit interface is the back side, that is, the sliding portion 512 is placed between the back side of the control panel 30 and the front side of the fixed bracket 52. Of course, the placement position of the sliding portion 512 can be determined according to actual conditions, and there is no limitation on this. For example, the sliding portion 512 can also be placed on the fixed bracket 52.

[0053] Among them, reference Figure 1 、 Figure 3 、 Figure 6 and Figure 7 As shown, the control panel 30, the sliding portion 512, and the fixing bracket 52 can be arranged along the second direction. The control panel 30 and the fixing bracket 52 limit the sliding portion 512 in the second direction to prevent the sliding portion 512 from moving in the second direction, thereby better ensuring that the sliding portion 512 slides in the first direction. The second direction is perpendicular to the first direction.

[0054] In some embodiments, reference Figures 1 to 4 As shown, the main body of the control panel 30 can be a plastic part. In addition to being an appearance component of the electrical device itself, the control panel 30 is mainly used to fix the circuit interface of the functional interface of the electrical device. The anti-misinsertion cover 51 can be a plastic part. After the anti-misinsertion cover 51 is installed from the back of the control panel 30, it is pressed with the fixing bracket 52, and then the fixing bracket 52 is fixed to the control panel 30 by tightening the screws, thereby achieving the fixation of the anti-misinsertion cover 51. In this embodiment, the USB interface and the photovoltaic charging interface can be integrated into the circuit board 40. The circuit board 40 is locked to the control panel 30 by fixing screws, and is exposed through the matching opening on the fixing bracket 52 and the notch on the control panel 30 for use by relevant personnel.

[0055] It should be noted that the control panel 30 , the circuit board 40 , the anti-misinsertion cover 51 and the fixing bracket 52 may be combined in other ways besides the above-mentioned combination, and this is not limited to any other combination.

[0056] Among them, reference Figures 5 to 7As shown, the sliding portion 512 and the shielding portion 511 can be connected via a connecting portion 513. The sliding portion 512 and the shielding portion 511 are arranged along the second direction, and the connecting portion 513 extends along the second direction, thereby achieving mutual connection between the sliding portion 512, the connecting portion 513, and the shielding portion 511. In some embodiments, the anti-misinsertion cover 51 can be an integrally molded plastic part to ensure the overall structural stability of the anti-misinsertion cover 51.

[0057] Among them, reference Figure 3 、 Figure 6 and Figure 7 As shown, the sliding portion 512 may include an arcuate convex edge 5121, which protrudes along the second direction away from the center of the shielding portion 511. The control panel 30 includes a chute 31 corresponding to the arcuate convex edge 5121, and the chute 31 and at least one side of the arcuate convex edge 5121 facing the chute 31 are in contact with each other. For example, the side of the arcuate convex edge 5121 facing the chute 31 can be recorded as the bottom surface, the bottom surface of the arcuate convex edge 5121 is in contact with the chute 31, and other surfaces (such as the side surfaces) of the arcuate convex edge 5121 are not in contact with the chute. For another example, the side of the arcuate convex edge 5121 facing the chute 31 can be recorded as the bottom surface, the bottom surface of the arcuate convex edge 5121 is in contact with the chute 31, and the side surfaces of the arcuate convex edge 5121 can also be in contact with the chute 31.

[0058] The contact between the curved convex edge 5121 and the chute 31 reduces the resistance of the sliding portion 512 relative to the control panel 30. Furthermore, the chute 31 and the curved convex edge 5121 are in elastic contact. By designing a preloaded fit between the chute 31 and the curved convex edge 5121, the balance of the anti-misinsertion cover 51 can be better maintained. Furthermore, the chute 31 retains space for preloaded elastic deformation, ensuring that the curved convex edge 5121 no longer makes hard contact when sliding within the chute 31, but rather elastic contact. This elastic contact can extend the lifespan of the curved convex edge 5121 and the chute 31.

[0059] Among them, reference Figures 5 to 7 As shown, the sliding portion 512 may be provided with a matching notch 5122 that matches the arcuate convex edge 5121. The matching notch 5122 is located on the side of the arcuate convex edge 5121 away from the slide groove 31. When the sliding portion 512 is a plastic part, by providing the above-mentioned matching notch 5122, the arcuate convex edge 5121 can be configured with movement space in the direction away from the slide groove 31, thereby better ensuring the elastic contact between the arcuate convex edge 5121 and the slide groove 31, and better extending the service life of the arcuate convex edge 5121 and the slide groove 31.

[0060] Among them, reference Figures 5 to 7As shown, the bottom of the chute 31 can be provided with at least one positioning tooth groove 32 corresponding to the arc-shaped convex edge 5121. When the arc-shaped convex edge 5121 slides along the chute 31 to the position of the positioning tooth groove 32, it can be snapped into the positioning tooth groove 32 to achieve positioning. By providing the positioning tooth groove 32, when there is no force acting on the anti-misinsertion cover 51, the anti-misinsertion cover 51 can remain stationary, thereby ensuring the stability of the anti-misinsertion cover 51. In addition, when relevant personnel push the anti-misinsertion cover 51 to slide, due to the provision of the positioning tooth groove 32, the relevant personnel can also have a slight jumping feeling when sliding, thereby improving the user experience. It should be noted that the number of positioning tooth grooves 32 can be set according to actual needs and is not limited to this. The control panel 30 is designed with tooth groove positioning corresponding to the chute 31 on the side of the sliding cover. When there is no force acting on the sliding cover, the sliding cover does not move, and there is also a slight jumping feeling when sliding.

[0061] In some embodiments, reference Figure 3 as well as Figures 5 to 7 As shown, the sliding portion 512 includes a first sliding sub-portion and a second sliding sub-portion, respectively located on either side of the shielding portion 511. The first sliding sub-portion includes two arcuate convex edges 5121, and the second sliding sub-portion includes two arcuate convex edges 5121. The arcuate convex edges 5121 of the first sliding sub-portion and the arcuate convex edges 5121 of the second sliding sub-portion are symmetrically arranged about the shielding portion 511. Accordingly, the slide groove 31 of the control panel 30 includes a first sub-slide groove that cooperates with the first sliding sub-portion, and a second sub-slide groove that cooperates with the second sliding sub-portion.

[0062] In this embodiment, the first sub-slot can be provided with two groups of positioning tooth grooves 32, and each group of positioning tooth grooves 32 can include two positioning tooth grooves 32, and these two positioning tooth grooves 32 correspond one-to-one to the corresponding two arc-shaped convex edges 5121. Among them, when the two arc-shaped convex edges 5121 are respectively snapped into the two positioning tooth grooves 32 in the first group of positioning tooth grooves 32, it means that the sliding portion 512 drives the shielding portion 511 to slide to the corresponding position of the first circuit interface 10, and the shielding portion 511 can achieve shielding of the first circuit interface 10. When the two arc-shaped convex edges 5121 are respectively snapped into the two positioning tooth grooves 32 in the second group of positioning tooth grooves 32, it means that the sliding portion 512 drives the shielding portion 511 to slide to the corresponding position of the second circuit interface 20, and the shielding portion 511 can achieve shielding of the second circuit interface 20. The structure of the second sub-slot can be symmetrical with that of the first sub-slot, and will not be described in detail here.

[0063] It should be noted that, in addition to the above-mentioned structures, the sliding portion 512 and the sliding groove 31 may also have other structures, which is not limited to this.

[0064] Among them, reference Figure 3 as well as Figures 5 to 7As shown, the front surface of the sliding portion 512 (i.e., the side of the sliding portion 512 facing the control panel 30) may be provided with at least one first contact point 5123. The first contact point 5123 abuts the back surface of the control panel 30 (i.e., the side of the control panel 30 facing the fixing bracket 52), and the portion of the control panel 30 abutting the first contact point 5123 is configured as a smooth surface. In other words, at least the portion of the back surface of the control panel 30 abutting the first contact point 5123 is configured as a smooth surface. This reduces the resistance of the sliding portion 512 relative to the control panel 30. Of course, the entire back surface of the control panel 30 may also be configured as a smooth surface, and this is not limited to this.

[0065] It should be noted that the number of first contact bone positions 5123 can be one, two, or even more, and there is no limitation thereto. The first contact bone positions 5123 and the end surfaces of the control panel 30 can be constructed as arc surfaces to reduce the contact area and further reduce the sliding resistance between the sliding portion 512 and the control panel 30.

[0066] Among them, reference Figure 3 as well as Figures 5 to 7 As shown, the reverse side of the sliding portion 512 (i.e., the side of the sliding portion 512 facing the fixed bracket 52) is provided with at least one second contact point 5124. The second contact point 5124 abuts the front side of the fixed bracket 52 (i.e., the side of the fixed bracket 52 facing the control panel 30), and the portion of the fixed bracket 52 abutting the second contact point 5124 is configured as a smooth surface. In other words, at least the portion of the front side of the fixed bracket 52 abutting the second contact point 5124 is configured as a smooth surface. This reduces the resistance of the sliding portion 512 relative to the fixed bracket 52. Of course, the entire front side of the fixed bracket 52 can also be configured as a smooth surface, and this is not limited to this.

[0067] It should be noted that the number of second contact bone sites 5124 can be one, two, or even more, and this is not limited to the following. For example, a segmented first contact bone site 5123 can be provided on the reverse side of the sliding portion 512, and the end surface of the first contact bone site 5123 that contacts the fixed bracket 52 can be configured as an arc surface to reduce the contact area and further reduce the sliding resistance between the sliding portion 512 and the fixed bracket 52.

[0068] Among them, reference Figure 1 、 Figure 3 as well as Figures 5 to 7As shown, the anti-misplacement structure 50 may further include a foolproof structure, which includes a foolproof post 531 and a foolproof groove 532 that cooperate with each other. One of the foolproof post 531 and the foolproof groove 532 is provided on the front side of the sliding portion 512, and the other of the foolproof post 531 and the foolproof groove 532 is provided on the back side of the control panel 30. The provision of the foolproof post 531 and the foolproof groove 532 can play a foolproof role in the installation of the anti-misplacement structure 50 and ensure that its installation direction is correct.

[0069] In some embodiments, reference Figure 3 and Figure 6 As shown, an anti-mistake post 531 is provided on the front of the sliding portion 512, and the anti-mistake post 531 is provided on the first sliding sub-section of the sliding portion 512. In addition, the second sliding sub-section of the sliding portion 512 can be provided with a first contact bone position 5123. On the back of the control panel 30, the side corresponding to the first sliding sub-section is provided with an anti-mistake groove 532, and the side corresponding to the second sliding sub-section is provided with a smooth surface. This ensures the correct installation of the anti-mistake insertion cover 51. The bottom and walls of the anti-mistake groove 532 can also be provided with smooth surfaces to further reduce the sliding resistance of the sliding portion 512 relative to the control panel 30.

[0070] It should be noted that, in addition to the sliding portion 512 and the control panel 30 of the above-mentioned structure, sliding portions 512 and control panels 30 of other structures may also be provided, and this is not limited.

[0071] In this embodiment, the anti-misinsertion cover 51 slides in a first direction (e.g., up and down) to prevent misinsertion and simultaneously protect unused circuit interfaces from dust. The circular arc convex edge of the sliding portion 512 elastically contacts the slide groove 31 of the control panel 30, ensuring smooth sliding movement and increasing the life of the slide. The positioning teeth 32 on the slide groove 31 of the control panel 30, combined with the circular arc convex edge, provide a unique, slightly bouncing feel during sliding, while also effectively positioning the anti-misinsertion cover 51.

[0072] The electrical device and its anti-misinsertion structure 50 of this embodiment can not only prevent the misinsertion of two incompatible circuit interfaces, but also provide dust protection for the circuit interface in an unused state. Moreover, there is no need to set the two circuit interfaces on different sides of the electrical device, which can avoid the dispersion of functional interfaces in the electrical device, ensure the overall aesthetics of the electrical device, and enhance the user experience. In addition, the first circuit interface 10 and the second circuit interface 20 of this embodiment can be set on the same side, and the two circuit interfaces have the same orientation and can be set on the same side of the same circuit board 40, which can reduce costs to a certain extent and also reduce the problem of electromagnetic interference radiation caused by cross-line connections.
