DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only 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.

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and claims of this application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0041] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0042] The "multiple" involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0043] The terms "parallel" and "perpendicular" in this application refer to "substantially parallel" and "substantially perpendicular" in actual operation. "Substantially parallel" can be understood as parallel with a certain error, and similarly, "substantially perpendicular" can be understood as perpendicular with a certain error.

[0044] In electrical equipment, the door panel of the chassis is usually electrically connected to the chassis frame through a grounding wire to achieve grounding of the door panel. Figure 1 As shown, one end of the grounding wire 001 is electrically connected to the door panel 1, and the other end of the grounding wire 001 is electrically connected to the chassis frame (not shown in the figure).

[0045] There are situations where electrical equipment needs to have its door panel 1 removed, for example, when electronic equipment needs maintenance. Removing the door panel 1 specifically includes: first releasing the mechanical connection between the door panel 1 and the chassis frame, and then removing the connection between the grounding wire 001 and the door panel 1, or the connection between the grounding wire 001 and the chassis frame. During the removal of the door panel 1, one person is required to manually support the door panel 1 and keep it from falling, while another person removes the grounding wire 001. This requires two people to remove the door panel 1, resulting in a high labor cost for removing the door panel; it also makes the removal of the door panel 1 more complicated and the removal efficiency of the door panel 1 lower.

[0046] In order to reduce the labor cost of disassembling the door panel, an embodiment of the present application provides a door panel grounding structure and electrical equipment.

[0047] The door panel grounding structure provided in the embodiment of the present application is applied to electrical equipment.

[0048] like Figure 2 、 Figure 3 and Figure 5 As shown, the door panel grounding structure provided in the embodiment of the present application includes: a door panel 1 and a grounding built-in component 2.

[0049] The door panel 1 is used to be detachably fixedly connected to a chassis frame (not shown) or other structures of an electronic device chassis, as long as the door panel 1 is detachably fixed.

[0050] The grounding built-in component 2 is used to electrically connect to the chassis frame or other structures of the electronic device chassis, as long as the grounding built-in component 2 is grounded and fixed. Exemplarily, the grounding built-in component 2 is used to electrically connect to the chassis frame, and the chassis frame is provided with a grounding interface, which is used to connect to the earth.

[0051] The grounding built-in component 2 can be in the shape of an elongated strip. For ease of installation, the grounding built-in component 2 can be selected to be perpendicular to the door panel 1. Of course, the grounding built-in component 2 and the door panel 1 can be selected to be relatively inclined.

[0052] In actual situations, the grounding built-in component 2 may also be in other shapes, which is not limited in the embodiment of the present application.

[0053] The grounding internal component 2 is provided with a second conductive member 4. When the door panel 1 is closed, the first conductive member 3 and the second conductive member 4 are in contact and electrically connected. When the door panel 1 is open, the first conductive member 3 and the second conductive member 4 are separated. It should be noted that the contact between the first conductive member 3 and the second conductive member 4 can be separated to ensure that the first conductive member 3 and the second conductive member 4 are separated when the door panel 1 is open.

[0054] When the door panel 1 is charged, the electricity carried by the door panel 1 can be quickly introduced into the chassis frame and then into the ground.

[0055] In the above-described door panel grounding structure, door panel 1 can be removed by releasing its fixed position, for example, by releasing the fixed connection between door panel 1 and the chassis frame. During this movement, door panel 1 can be opened, and first conductive member 3 and second conductive member 4 can be separated, thereby releasing the grounding of door panel 1. Therefore, door panel 1 can be removed by releasing its fixed position. This allows one person to complete the removal of door panel 1, reducing the labor cost of removing door panel 1 compared to existing techniques. This can also reduce maintenance costs for electrical equipment when door panel 1 is removed.

[0056] It should be noted that one person can also complete the installation of the door panel 1, which reduces the labor cost of installing the door panel 1 and thus reduces the assembly cost of the electrical equipment.

[0057] In the above-described door panel grounding structure, door panel 1 can be removed by releasing the fixings. Compared with the prior art, there is no need to separately release the grounding, which effectively simplifies the steps required to remove door panel 1 and improves the efficiency of door panel 1 removal. In the case where door panel 1 needs to be removed for maintenance of electrical equipment, the maintenance efficiency of the electrical equipment can also be improved.

[0058] Correspondingly, in the above-mentioned door panel grounding structure, by fixing the door panel 1, the door panel 1 can be closed and the first conductive member 3 and the second conductive member 4 can be in contact, thereby achieving grounding. In this way, the installation of the door panel 1 can be completed by fixing the door panel 1. Compared with the existing technology, there is no need to ground the door panel 1 separately, which effectively simplifies the steps required for installing the door panel 1 and improves the installation efficiency of the door panel 1.

[0059] The door panel grounding structure provided in the embodiment of the present application realizes electrical connection between the door panel 1 and the grounding built-in component 2 by means of contact and electrical conduction between the first conductive member 3 and the second conductive member 4. Since the grounding built-in component 2 is electrically connected to the chassis frame and the chassis frame is grounded, the door panel 1 is grounded. Compared with grounding the door panel 1 with a grounding wire, this avoids the grounding wire being squeezed and damaged by the door panel 1 due to being too long, thereby reducing the impact on the grounding reliability; it also avoids the inability to achieve grounding due to the grounding wire being too short. Therefore, the door panel grounding structure provided in the embodiment of the present application improves the grounding reliability of the door panel 1.

[0060] In the embodiment of this application, Figure 2 、 Figure 3 and Figure 5 As shown, the door panel 1 includes a door panel body 11, a sealing ring 12 and a reinforcing rib 13 fixed to the door panel body 11; wherein the sealing ring 12 and the reinforcing rib 13 both protrude from the door panel body 11, the sealing ring 12 is located on the periphery of the reinforcing rib 13, and there is a gap between the sealing ring 12 and the reinforcing rib 13.

[0061] In the door panel 1, the reinforcement rib 13 and the door panel body 11 can be an integrated structure or a split structure. In the case of a split structure, the reinforcement rib 13 and the door panel body 11 are detachably fixedly connected to each other to facilitate installation and removal. Exemplarily, the reinforcement rib 13 is fixed to the door panel body 11 by fasteners.

[0062] To improve the grounding reliability of the door panel 1, when the door panel 1 is closed, the grounding insert 2 is located between the sealing ring 12 and the reinforcing rib 13. This way, the sealing ring 12 and the reinforcing rib 13 can limit the position of the grounding insert 2, reducing the chance of the grounding insert 2 shaking and thus improving the grounding reliability of the door panel 1.

[0063] In actual situations, the grounding built-in component 2 may be located at other positions of the door panel 1 when the door panel 1 is in a closed state, and this embodiment of the present application does not limit this.

[0064] Because the first and second conductive members 3 and 4 conduct electricity through contact, improving grounding reliability requires enhancing the contact reliability of the first and second conductive members 3 and 4. In some embodiments, at least one of the first and second conductive members 3 and 4 is an elastic member 3a that can deform in the thickness direction of the door panel 1. When the door panel 1 is closed, the elastic member 3a deforms to bring the first and second conductive members 3 and 4 into contact. This deformation of the elastic member 3a increases the contact force between the first and second conductive members 3 and 4, improving the reliability of the contact between the first and second conductive members 3 and 4, and thereby enhancing the grounding reliability of the door panel 1.

[0065] For example, Figure 2 and Figure 3 As shown, the first conductive member 3 is an elastic member 3a; Figure 5 As shown, the second conductive member 4 is an elastic member 3 a; the first conductive member 3 and the second conductive member 4 are both elastic members 3 a.

[0066] In the case that both the first conductive member 3 and the second conductive member 4 are elastic members 3 a , the structures of the first conductive member 3 and the second conductive member 4 are different. The specific structures of the first conductive member 3 and the second conductive member 4 are selected according to actual conditions.

[0067] In actual situations, in order to simplify the door panel grounding structure, the first conductive member 3 or the second conductive member 4 may be selected as the elastic member 3 a.

[0068] After the electrical equipment is maintained, in order to ensure that the elastic part 3a can still conduct electricity normally, the elastic part 3a can be selected to be able to undergo elastic deformation in the thickness direction of the door panel 1. In this way, when the door panel 1 is in the open state, the elastic part 3a can be restored to its original state to ensure that after the door panel 1 is reinstalled, the first conductive part 3 and the second conductive part 4 can still be abutted.

[0069] The specific structure of the elastic member 3a is selected based on actual conditions. In some embodiments, the elastic member 3a includes a conductive fixing portion 31 and a conductive connecting portion 33 that can deform in the thickness direction of the door panel 1. The door panel 1 or the grounding built-in component 2 on which the elastic member 3a is located is electrically and fixedly connected to the conductive fixing portion 31, and the conductive connecting portion 33 is connected to the conductive fixing portion 31. When the door panel 1 is closed, the conductive connecting portion 33 deforms to abut the first conductive member 3 and the second conductive member 4. In this way, the conductive connecting portion 33 can deform without the conductive fixing portion 31 needing to deform, thereby ensuring the reliability of the connection between the elastic member 3a and the door panel 1 or the grounding built-in component 2, thereby improving grounding reliability. Furthermore, the conductive connecting portion 33 can deform, making it easier to control the amount of deformation, thereby ensuring grounding reliability.

[0070] It is understood that the conductive connecting portion 33 and the conductive fixing portion 31 are electrically connected in addition to being mechanically connected. When the elastic member 3a is capable of elastic deformation, the conductive connecting portion 33 is also capable of elastic deformation in the thickness direction of the door panel 1. Thus, when the door panel 1 is opened, the conductive connecting portion 33 can return to its original state, ensuring that the first conductive member 3 and the second conductive member 4 can still abut against each other after the door panel 1 is reinstalled.

[0071] In order to facilitate the elastic deformation of the conductive connecting part 33 in the thickness direction of the door panel 1, the elastic part 3a can be selected as a copper part. This not only ensures that the elastic part 3a can undergo elastic deformation, but also facilitates reducing the resistance of the elastic part 3a, thereby improving the electrical connection reliability of the first conductive part 3 and the second conductive part 4, thereby improving the grounding reliability of the door panel 1.

[0072] In actual situations, the first conductive member 3 and the second conductive member 4 may also be made of other conductive materials, which is not limited in this embodiment of the present application.

[0073] like Figure 4 As shown, to facilitate deformation of the conductive connecting portion 33, the elastic member 3a further includes a conductive transition portion 32. The conductive connecting portion 33 is indirectly connected to the conductive fixing portion 31 via the conductive transition portion 32. A predetermined distance exists between the conductive connecting portion 33 and the conductive fixing portion 31 in the thickness direction of the door panel 1. This allows the conductive transition portion 32 to provide deformation space for the conductive connecting portion 33, facilitating deformation.

[0074] The conductive transition portion 32 may be deformable in the thickness direction of the door panel 1 or may not be deformable in the thickness direction of the door panel 1. Figure 4As shown, in some embodiments, the conductive transition portion 32 is a bent structure that can deform in the thickness direction of the door panel 1. In this way, after the conductive connection portion 33 deforms and fails (the conductive connection portion 33 cannot deform), the conductive transition portion 32 can deform in the thickness direction of the door panel 1, so that the conductive connection portion 33 (the first conductive member 3) can still abut against the second conductive member 4, or the conductive connection portion 33 (the second conductive member 4) can still abut against the first conductive member 3, effectively improving the grounding reliability of the door panel 1.

[0075] It should be noted that the bending structure may include a straight-line bend, a curved bend, or a straight-line bend and a curved bend.

[0076] The specific shape of the conductive transition portion 32 is selected according to actual conditions and is not limited in the embodiment of the present application.

[0077] To simplify the structure of the structural elastic member 3a, the conductive transition portion 32 and the conductive connection portion 33 can be located on the same side of the conductive fixing portion 31, with the conductive connection portions 33 located at both ends of the conductive transition portion 32. This allows the position of the grounding built-in component 2 to be adjusted so that the second conductive member 4 on the grounding built-in component 2 contacts and is electrically connected to the conductive connection portion 33 at one end of the conductive transition portion 32.

[0078] In actual situations, the conductive connection portion 33 may also be selected to be distributed at one end of the conductive transition portion 32 , and is not limited to the above embodiment.

[0079] like Figure 2-Figure 4 As shown, the first conductive member 3 is an elastic member 3a. Based on this, the conductive fixing portion 31 and the reinforcing rib 13 are fixedly and electrically connected, the conductive transition portion 32 and the conductive connecting portion 33 are located between the sealing ring 12 and the reinforcing rib 13, and a portion of the conductive connecting portion 33 abuts against the door panel body 11. This ensures that when the door panel 1 is closed, the grounding internal component 2 is located between the sealing ring 12 and the reinforcing rib 13. This also ensures that the conductive transition portion 32 and the reinforcing rib 13 are in a positionally limited fit, reducing the possibility of the elastic member 3a shaking and improving the grounding reliability of the door panel 1.

[0080] In actual practice, the second conductive member 4 can also be the elastic member 3a described above (the elastic member 3a includes a conductive fixing portion 31, a conductive transition portion 32, and a conductive connecting portion 33). Specifically, the conductive fixing portion 31 is fixedly connected and electrically connected to the grounding internal member 2. When the door panel 1 is closed, the conductive fixing portion 31 is located between the sealing ring 12 and the reinforcing rib 13, the conductive transition portion 32 and the conductive connecting portion 33 are both opposite the reinforcing rib 13, and the conductive connecting portion 33 and the first conductive member 3 on the reinforcing rib 13 are against each other. In this way, when the door panel 1 is closed, the grounding internal member 2 is located between the sealing ring 12 and the reinforcing rib 13, and the conductive transition portion 32 and the reinforcing rib 13 are limitedly matched, which reduces the probability of the elastic member 3a shaking and improves the grounding reliability of the door panel 1.

[0081] In the embodiment of the present application, the elastic member 3a may also not include the conductive transition portion 32. Figure 5 and Figure 6 As shown, the conductive connecting portion 33 is directly connected to the conductive fixing portion 31. In this way, the structure of the entire elastic member 3a is simplified.

[0082] In the elastic member 3a, in order to facilitate deformation of the conductive connection portion 33 in the thickness direction of the door panel 1, the conductive connection portion 33 may be a bent structure capable of deformation in the thickness direction of the door panel 1. The bent structure may include a straight bend, a curved bend, or both a straight bend and a curved bend.

[0083] The specific structure of the bending structure is selected according to actual conditions. In some embodiments, the first end of the conductive connection portion 33 can be referred to as the conductive connection portion first end 333, the second end of the conductive connection portion 33 can be referred to as the conductive connection portion second end 334, and the middle portion of the conductive connection portion 33 can be referred to as the conductive connection portion middle portion 335. The conductive connection portion first end 333 is connected to the conductive fixing portion 31. When the elastic member 3a includes a conductive transition portion 32, the conductive connection portion first end 333 is connected to the conductive fixing portion 31 through the conductive transition portion 32. The conductive connection portion second end 334 is away from the conductive fixing portion 31, and the conductive connection portion middle portion 335 is located between the conductive connection portion first end 333 and the conductive connection portion second end 334.

[0084] like Figure 2-Figure 4As shown, when the first conductive member 3 is an elastic member 3a, the middle portion 335 of the conductive connection portion is farther away from the door panel 1 than the first end 333 and the second end 334 of the conductive connection portion. Thus, the middle portion 335 of the conductive connection portion first contacts the second conductive member 4. As the door panel 1 closes, the first conductive member 3 presses the second conductive member 4, causing the middle portion 335 of the conductive connection portion to move toward the door panel 1. This deforms the conductive connection portion 33, thereby causing the entire conductive connection portion 33 or a portion of the conductive connection portion 33 to abut against the second conductive member 4, thereby improving the grounding reliability of the door panel 1.

[0085] In the case where the first conductive member 3 is an elastic member 3a, the second end 334 of the conductive connection portion can also be selected to be farther away from the door panel 1 than the first end 333 of the conductive connection portion. In this way, the second end 334 of the conductive connection portion first contacts the second conductive member 4. As the door panel 1 closes, the first conductive member 3 presses the second conductive member 4, causing the second end 334 of the conductive connection portion to move toward the door panel 1. In other words, the conductive connection portion 33 is deformed, thereby achieving abutment between the entire conductive connection portion 33 or a portion of the conductive connection portion 33 and the second conductive member 4, thereby improving the grounding reliability of the door panel 1.

[0086] In the above structure, when the door panel 1 is open, at least one of the first end 333 of the conductive connector and the second end 334 of the conductive connector can be in contact with the door panel 1. This can increase the force between the conductive connector 33 and the second conductive member 4, thereby increasing the deformation of the conductive connector 33 and improving the grounding reliability of the door panel 1. Alternatively, when the door panel 1 is open, neither the first end 333 of the conductive connector nor the second end 334 of the conductive connector can be in contact with the door panel 1.

[0087] like Figure 5 and Figure 6 As shown, when the second conductive member 4 is an elastic member 3a, the second end 334 of the conductive connection portion is further away from the grounding internal component 2 than the first end 333 of the conductive connection portion. Thus, the first conductive member 3 first contacts the second end 334 of the conductive connection portion. As the door panel 1 closes, the first conductive member 3 presses the second conductive member 4, causing the second end 334 of the conductive connection portion to move toward the grounding internal component 2. This deforms the conductive connection portion 33, causing the entire conductive connection portion 33, or a portion thereof, to abut against the first conductive member 3, thereby improving the grounding reliability of the door panel 1.

[0088] If the second conductive member 4 is an elastic member 3a, the middle portion 335 of the conductive connection portion can also be positioned farther from the grounded internal component 2 than the first end 333 and the second end 334 of the conductive connection portion. In this way, the first conductive member 3 first contacts the middle portion 335 of the conductive connection portion. As the door panel 1 closes, the first conductive member 3 presses the second conductive member 4, causing the middle portion 335 of the conductive connection portion to move toward the grounded internal component 2. This deforms the conductive connection portion 33, causing the entire conductive connection portion 33, or a portion thereof, to abut against the first conductive member 3, thereby improving the grounding reliability of the door panel 1.

[0089] In some other embodiments, the conductive connection portion 33 may have other bent structures and is not limited to the above embodiment.

[0090] To facilitate the formation of a folded structure, the conductive connecting portion is a conductive connecting sheet. Accordingly, if the conductive transition portion 32 has a folded structure, the conductive transition portion 32 can be a conductive transition sheet. Based on this, the entire elastic member 3a can be a spring sheet with a folded structure. In this case, the conductive fixing portion 31 is a conductive fixing sheet.

[0091] The thickness of the shrapnel should be designed according to the actual situation, as long as the elasticity of the shrapnel is guaranteed.

[0092] For example, Figure 4 As shown, the conductive connection portion 33 includes a first connection piece 331 and a second connection piece 332. The first connection piece 331 is connected to the conductive transition portion 32, and an obtuse angle is formed between the first connection piece 331 and the second connection piece 332. The first connection piece 331 and the second connection piece 332 are symmetrically arranged about the connection plane between the first connection piece 331 and the second connection piece 332. The end where the first connection piece 331 and the conductive transition portion 32 are connected is the first end 333 of the conductive connection portion, the end of the second connection piece 332 away from the first connection piece 331 is the second end 334 of the conductive connection portion, and the junction between the first connection piece 331 and the second connection piece 332 is the middle portion 335 of the conductive connection portion.

[0093] For example, Figure 6 As shown, the conductive connecting portion 33 includes a first connecting piece 331 and a second connecting piece 332. The first connecting piece 331 is connected to the conductive fixing portion 31. There is an obtuse angle between the first connecting piece 331 and the conductive fixing portion 31. There is also an obtuse angle between the first connecting piece 331 and the second connecting piece 332. The conductive fixing portion 31 and the second connecting piece 332 are inclined relative to each other. The end where the first connecting piece 331 and the conductive fixing portion 31 are connected is the first end 333 of the conductive connecting portion, and the end of the second connecting piece 332 away from the first connecting piece 331 is the second end 334 of the conductive connecting portion.

[0094] In the embodiment of the present application, the elastic member 3a may also be selected as other deformable structures, such as deformation through a spring structure, etc. Correspondingly, the conductive connection portion 33 may be deformed through a spring structure, which is not limited in the embodiment of the present application.

[0095] In the embodiment of the present application, the entire elastic member 3a can also be selected to be deformable in the thickness direction of the door panel 1, and is not limited to the structure described above.

[0096] In the above door panel grounding structure, the first conductive member 3 and the second conductive member 4 are in contact, which may be surface contact, line contact or point contact. To improve grounding reliability, the contact structure of the first conductive member 3 and the second conductive member 4 is a surface contact structure.

[0097] In the above-described door panel grounding structure, the first conductive member 3 and the second conductive member 4 can each be one, or both can be two or more. To improve the grounding reliability of the door panel 1, there are at least two first conductive members 3, distributed on both sides of the door panel 1 along a predetermined direction parallel to the door panel 1. Exemplarily, the predetermined direction is the width, length, or other direction of the door panel 1.

[0098] Accordingly, there are at least two second conductive members 4 and grounding built-in members 2 , and the second conductive members 4 correspond to the first conductive members 3 one by one, and the grounding built-in members 2 correspond to the second conductive members 4 one by one.

[0099] In the embodiment of the present application, the first conductive member 3 and the door panel 1 are fixedly connected and electrically connected at the same time. As the operation time of the electrical equipment increases, the door panel 1 is more susceptible to corrosion and rust, affecting the reliability of the connection between the first conductive member 3 and the door panel 1. In order to solve this problem, Figure 3 As shown, the area in the door panel 1 that is fixedly connected to the first conductive member 3 has an anti-corrosion layer 5. This can reduce the chance of the area in the door panel 1 that is fixedly connected to the first conductive member 3 being corroded and rusted, thereby improving the reliability of the connection between the first conductive member 3 and the door panel 1 and thus improving the grounding reliability of the door panel 1.

[0100] The above-mentioned anti-corrosion layer 5 can be obtained by shielding spraying, that is, the anti-corrosion layer 5 is a shielding spray coating. Of course, the anti-corrosion layer 5 can also be obtained by other methods, and the embodiment of the present application does not limit this.

[0101] Other locations in the door panel 1, such as the area in contact with the conductive connection portion 33, may or may not be provided with the anti-corrosion layer 5, and this is not limited in the present embodiment. To reduce the resistance of the entire grounding circuit, the area in contact with the conductive connection portion 33 in the door panel 1 may be provided without the anti-corrosion layer 5.

[0102] In the embodiment of the present application, the first conductive member 3 and the door panel 1 may be a separate structure or an integrated structure.

[0103] In the case where the first conductive member 3 and the door panel 1 are of a separate structure, the first conductive member 3 and the door panel 1 can be detachably fixedly connected to facilitate replacement of the first conductive member 3. Exemplarily, the first conductive member 3 and the door panel 1 are connected by fasteners.

[0104] When the first conductive member 3 and the door panel 1 are an integrated structure, the first conductive member 3 is a part of the door panel 1 , and the first conductive member 3 can be understood as a part of the inner wall of the door panel 1 close to the chassis frame.

[0105] In the embodiment of the present application, the second conductive component 4 and the grounding built-in component 2 can be a separate structure or an integrated structure.

[0106] When the second conductive member 4 and the grounding built-in member 2 are separate structures, the second conductive member 4 and the grounding built-in member 2 can be detachably fixedly connected to facilitate replacement of the second conductive member 4. Exemplarily, the second conductive member 4 and the grounding built-in member 2 are connected by fasteners.

[0107] When the second conductive member 4 and the grounding built-in member 2 are an integrated structure, the second conductive member 4 is a part of the grounding built-in member 2 . The second conductive member 4 can be understood as a part of the end of the grounding built-in member 2 close to the door panel 1 .

[0108] In the embodiment of the present application, in order to simplify the structure, as shown in FIG. Figure 2 and Figure 3 As shown, the first conductive member 3 and the door panel 1 can be selected as a separate structure, and the second conductive member 4 and the grounding built-in member 2 can be selected as an integrated structure; or Figure 5 As shown, the first conductive member 3 and the door panel 1 are an integrated structure, and the second conductive member 4 and the grounding built-in member 2 are a separate structure.

[0109] Of course, the first conductive member 3 and the door panel 1 may be a split structure, and the second conductive member 4 and the grounding built-in member 2 may be a split structure; or the first conductive member 3 and the door panel 1 may be an integrated structure, and the second conductive member 4 and the grounding built-in member 2 may be an integrated structure.

For example, the power electronic device may be an inverter, a power distribution cabinet, etc., which is not limited in the embodiment of the present application.
