[0064] The core of the present application is to provide a sealing structure and an electronic cabinet to solve the problem that the sealing effect of the sealing structure between two cabinet cavities with different protection levels is not easily guaranteed.

[0065] 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.

[0066] Electronic cabinet is a kind of housing specially used to house and protect electronic equipment, which is widely used in the fields of integrated wiring and distribution products, computer network equipment, electronic equipment stacking scenes and communication equipment. Figure 6 As shown, the electronic cabinet 3 often adopts a cavity-based protection method. The electronic device 1 requiring a higher protection level is placed in the cabinet cavity 31 with a higher protection level, while the electronic device 1 requiring a lower protection level is placed in the cabinet cavity 31 with a lower protection level. At the same time, since the electronic devices 1 in the electronic cabinet form the entire circuit system, the electrical devices 1 in different cabinet cavities 31 need to be connected through electrical connectors 4 (such as busbars or busbars, etc.). Generally, the interior of the electronic cabinet 3 is divided into two or more cabinet cavities 31 by a partition 32. When the electrical connector 4 is connected, it needs to pass through the partition 32 of two adjacent cabinet cavities 31, and sealing and insulation need to be ensured when passing through. Usually, the sealing and insulation method for the electrical connector 4 passing through the partition 32 is to use insulating material at the position where the electrical connector 4 passes through the partition 32, and the gap between the insulating material and the electrical connector is sealed with glue. However, the structural form of the electrical connector 4 passing through the partition 32 is not suitable for rapid production of products on the assembly line, and the construction quality of the production line seal is not convenient for rapid inspection of the production line. Therefore, the quality of its sealing structure is not easy to control, which leads to the sealing effect of this sealing structure being difficult to guarantee.

[0067] Based on this, refer to Figure 6 Combine Figure 1-Figure 5 As shown, an embodiment of the present application provides a sealing structure for an electrical connector 4 to pass through a partition 32 inside an electronic cabinet 3 in a sealed and insulated manner. The sealing structure specifically includes an insulating plate 12 and an interface assembly 2 .

[0068] Reference Figure 1 Combine Figure 2As shown, the insulating plate 12 is provided on the electronic device 1 and has a through hole 121 for the connection terminal 11 of the electronic device 1 to pass through in a sealed manner. There is no specific limitation on the material of the insulating plate 12, as long as it can meet the insulation requirements of the application scenario. Among them, when the connection terminal 11 can be specifically designed as an inlet and outlet line bar (which can be made of a copper bar or an aluminum bar), the corresponding through hole 121 is an opening corresponding to the cross-sectional size of the inlet and outlet line bar; in addition, when the connection terminal 11 is sealed through the through hole 121, the sealing method used for the gap between the two can be specifically Sealing can be done by potting glue, or other sealing methods such as sealing strips, which are not limited in detail here; in addition, fixing holes can be designed on the insulating plate 12, and it is fixed to the corresponding position of the electronic device 1 through the fixing holes. On the one hand, the insulating plate 12 has insulation protection capabilities for the terminal block 11, and on the other hand, it also has a supporting and fixing function. On the other hand, the terminal block 11 can form a sealing interface with the interface component 2 through the insulating plate 12. The sealing interface can be a plane or a curved surface. In actual application, the configuration can be selected according to needs.

[0069] Reference Figure 3-Figure 5 As shown, the interface assembly 2 may specifically include a pipe body 21 and a first interface end 24 and a second interface end 25 provided at both ends of the pipe body 21; wherein the pipe body 21 is a structure similar to a pipe, and the first interface end 24 is sealedly connected to the mounting opening 33 on the partition 32 inside the electronic cabinet 3. Specifically, the first interface end 24 may be designed as a flange structure, but is not limited to being fixed to the partition 32 by fasteners, and the second interface end 25 is sealedly connected to the insulating plate 12, and a through hole 121 is provided on the inner side of the second interface end 25, so that the position where each terminal 11 is connected to the electrical connector 4 is located within the pipe body 21. It should be understood by those skilled in the art that the pipe body 21, the first interface end 24, and the second interface end 25 of the interface assembly 2 may be designed as an integrated structure or as a split connection structure.

[0070] In actual application, this sealing structure is that the insulating plate 12 is set on the electronic device 1, and the terminal 11 seals and penetrates the through hole 121 on the insulating plate 12. During the assembly process of the whole machine, the first interface end 24 is sealed and connected to the installation opening 33 on the partition 32 in the electronic cabinet 3, and is sealed and connected to the insulating plate 12 through the second interface end 25. The through hole 121 is located on the inner side of the second interface end 25. Then, the insulating plate 12 and the pipe body 21 of the interface component 2 constitute the separation interface of the electronic device 1 at the installation opening 33 of the partition 32. At this time, the terminal 11 can pass through the partition 32 in a sealed and insulated manner, thereby ensuring the reliability of the sealing structure. Among them, the insulating plate 12 is installed on the electronic device 1 and the terminal 11 seals and penetrates the through hole 121 of the insulating plate 12. It is suitable for batch production and batch inspection on the assembly line, and the quality is easier to control. Therefore, the sealing effect of the sealing structure is easier to be guaranteed, and the interface component 2 can be quickly installed on the production line through the first interface end 24 and the second interface end 25.

[0071] It should be noted that the number of the connection terminals 11 of the electronic device 1 can be designed according to the application scenario, and without loss of generality, the electronic device 1 has input and output sides, of course, it can also be only one side (that is, the input and output are on the same side), or arranged on two or more sides. Figure 1 For example, the connection terminal 11 of the electronic device 1 has a three-phase input and a three-phase output, and the three-phase input is arranged on the first side of the electronic device 1, and the three-phase output is arranged on the second side of the electronic device 1, and the first side and the second side are two opposite sides.

[0072] In some specific embodiments, reference Figure 1 and Figure 7-10 The insulating plate 12 mounted on the electronic device 1 can be specifically designed to be arranged in parallel with the partition 32. The advantage of this arrangement is that it is easy to design and easy to implement. It can also be designed to refer to Figure 11-Figure 15 The insulating plate 12 and the partition 32 are arranged at an angle, and the specific structural form of the angle is reflected in that it gradually deviates from the partition 32 along a preset direction. For details, see Figure 11 The angle α in the figure is shown; wherein, the preset direction is the direction in which the electronic device 1 is installed into the corresponding cabinet cavity 31 in the electronic cabinet 3. The installation direction mainly depends on the installation opening opened by the cabinet cavity 31. The electronic device 1 is installed into the cabinet cavity 31 through the installation opening. The installation opening can be specifically designed to be in the front, back, top, bottom, left or right of the cabinet cavity 31. In actual application, the setting can be selected according to actual needs. Taking the installation opening designed in the front of the cabinet cavity 31 as an example, the installation direction is from the front of the cabinet cavity 31, specifically Figure 13 and Figure 14The direction indicated by the medium-thick solid arrow. The advantage of this arrangement is that it is easy to install.

[0073] In order to facilitate those skilled in the art to better understand the two different arrangements of the insulating plate 12, the following is an explanation in conjunction with a specific installation process:

[0074] by Figure 7-10 For example, the insulating plate 12 and the partition 32 are arranged in parallel, and the inner cavity of the electronic cabinet 3 is divided into three cabinet cavities 31 by the partition 32. The figure only shows the electronic device 1 in the middle cabinet cavity 31, and the electronic devices in the cabinet cavities 31 on both sides are not shown. Since the insulating plate 12 and the partition 32 are arranged in parallel, if the pipe body 21 of the interface component 2 is a rigid pipe body, then in order to achieve the smooth installation of the electronic device 1, it is necessary to first load the electronic device 1 into the middle cabinet cavity 31 along the loading direction, and then connect the electrical connector 4 to the terminal 11. The connection method can be but is not limited to the lap connection fixing method. The specific fixation can be lap fastener fixation, or lap welding, etc., which is not limited here; then the interface component 2 is inserted into the busbar mounting opening 33 from the cabinet cavity 31 on the side and the second interface end 25 is pressed and sealed on the insulating plate 12, and the first interface end 24 is fixed on the partition 32 at the same time.

[0075] by Figure 11-Figure 15 For example, taking the installation opening designed at the front of the cabinet cavity 31 as an example, the installation direction is from the front of the cabinet cavity 31, the insulating plate 12 and the partition 32 are arranged at an angle, and the inner cavity of the electronic cabinet 3 is divided into three cabinet cavities 31 by the partition 32. The figure only shows the electronic device 1 in the middle cabinet cavity 31, and the electronic devices in the cabinet cavities 31 on both sides are not shown. Since the insulating plate 12 and the partition 32 are arranged at an angle α, and the specific structural form of the angle is reflected in that it gradually deviates from the partition 32 along the preset direction, at this time, if the pipe body 21 of the interface component 2 is a rigid pipe body, then the end face of the second interface end 25 of the interface component 2 should also be designed as a matching inclined surface, similar to a wedge-shaped structure. For details, please refer to Figure 12 At that time, the installation process is not limited to the installation order of first installing the electronic device 1 and then installing the interface component 2. The interface component 2 can also be installed first and then the electronic device 1. In the process of installing the electrical device 1, the electronic device 1 can be pushed in along the installation direction. As the electronic device 11 is pushed in, the insulation plate 12 and the second interface end 25 of the interface component 2 are continuously compressed. The second interface end 25 can be designed with a sealing strip with a certain compression capacity. The size design can make the sealing strip reach a certain compression amount, thereby realizing a compression-sealed connection.

[0076] It should be noted that since the insulating plate 12 and the partition 32 are arranged at an angle α, they are not restricted to installing the electronic device 1 first. Therefore, the first interface end 24 of the interface assembly 2 can be designed as a structure that is fixedly connected to the partition 32 in a split manner, or it can be designed as an integrated structure, such as by welding.

[0077] It is worth mentioning that, in addition to being designed as a rigid pipe body, the pipe body 21 can also be designed as a flexible and retractable pipe. The embodiment in which the pipe body 21 is designed as a flexible and retractable pipe will be described in detail later.

[0078] In a further embodiment, referring to Figure 7-Figure 15 As shown, the number of the above-mentioned insulating plates 12 can be two, and they are respectively arranged on both sides of the electronic device 1. For example, one side is the input side of the electronic device 1, and the other side is the output side of the electronic device 1. If the insulating plate 12 and the partition 32 are arranged at an angle α, the angle between the two insulating plates 12 is Figure 11 and Figure 14 As shown in the angle β, as the electronic device 1 is pushed in, the insulating plates 12 on both sides squeeze and tighten the end faces of the second interface ends 25 on their respective corresponding sides. Under this structural form, the forces on both sides of the electronic device 1 are more uniform, making the installation more stable.

[0079] In some specific embodiments, reference Figure 3-Figure 5 As shown, the first interface end 24 and the partition 32 can be connected by compression, and a first sealing ring 23 is provided between the first interface end 24 and the partition 32. Sealing is achieved by pressing the first sealing ring 23, and the sealing structure is simpler and easier to install. Similarly, the second interface end 25 and the insulating plate 12 can also be designed to be compressed, and a second sealing ring 22 is provided between the second interface end 25 and the insulating plate 12. Sealing is achieved by pressing the second sealing ring 25, and the sealing structure is simpler and easier to install. Of course, it can be understood that the sealing structure using a sealing ring to compress is only an example of the embodiment of the present application. In actual application, other compression sealing structures commonly used by those skilled in the art can also be used, such as applying a sealing layer to achieve compression.

[0080] In some other specific embodiments, referring to Figure 16 and Figure 17 As shown, the pipe body 21 can be constructed as a flexible and retractable pipe. By designing it into this structural form, the size of the flexible and retractable pipe can be compressed to a certain amount in the channel direction and can also be pulled back to its original length. That is, the size of the flexible and retractable pipe is adjustable within a certain range in the channel direction. This not only makes the installation of the electronic cabinet 3 more convenient, but also allows for a wider range of processing errors. Figure 22The electronic device 1 and the first interface end 24 of the interface assembly 2 can be installed first, and then the flexible and retractable pipe can be compressed to expose the connection position of the terminal 11 and the electrical connector 4 to perform the wiring connection operation. Then, the flexible and retractable pipe can be extended to press the second interface end 25 against the insulating plate 12 to complete the connection operation. The connection method can be, but is not limited to, fastener connection and compression.

[0081] It should be noted that the flexible telescopic pipe can be made of, but not limited to, silicon titanium canvas stitched together and sealed with sealant to seal the gap, or other telescopic pipe structures known to those skilled in the art, the first interface end 24 and the second interface end 25 are rigid parts, which are respectively sealed and connected to the two ends of the flexible telescopic pipe, and can be connected by, but not limited to, rivet-assisted adhesive sealing, see Figure 17 As shown, the second sealing ring 23 and the first sealing ring 22 are respectively designed on the compression sealing end surfaces corresponding to the first interface end 24 and the second interface end 25.

[0082] In a further implementation scheme, since the pipe body 21 is constructed as a flexible and retractable pipe, the installation of the interface assembly 2 does not affect the installation of the electronic device 1. At that time, the first interface end 24 can be designed to be connected to the side of the partition 32 away from the second interface end 25; the first interface end 24 can also be designed to be connected to the side of the partition 32 close to the second interface end 25. In actual application, the configuration can be selected according to specific needs, and no specific limitation is made here.

[0083] It is worth mentioning that when the pipe body 21 is constructed as a flexible and retractable pipe, the connection between the first interface end 24 and the partition 32 can be constructed as a split connection structure or an integrated fixed connection, such as a welding connection.

[0084] In some other specific embodiments, referring to Figure 3-Figure 5 and Figure 17 As shown, at least one of the first interface end 24 and the second interface end 25 can be configured as a flange docking end, that is, one of the first interface end 24 and the second interface end 25 is designed as a flange docking end, for example Figure 3-Figure 5 The first interface end 24 shown is designed as a flange docking end; or as a reference Figure 17 As shown, the first interface end 24 and the second interface end 25 are both designed as flange butt ends. By designing the structural form of the flange butt ends, sealing and compression can be achieved by fasteners, and the structure is simple and easy to operate.

[0085] In another embodiment, referring to Figure 5-10 and Figure 13-Figure 22The present application also provides an electronic cabinet, comprising a cabinet cavity and a partition 32 disposed within the cabinet cavity. The partition 32 divides the cabinet cavity into a plurality of cabinet cavities 31. The electronic devices 1 within two adjacent cabinet cavities 31 are connected via electrical connectors 4 that pass through corresponding partitions 32. A sealing structure is provided at the location where the electrical connectors 4 pass through the partitions 32. This sealing structure is the same as that described in any of the aforementioned solutions. The electrical connectors 4 are connected to the wiring terminals 11 within the conduit body 21 of the interface assembly 2. Since the aforementioned sealing structure has the aforementioned technical effects, an electronic cabinet having this sealing structure should also have the corresponding technical effects, which will not be further described here.

[0086] In some specific embodiments, when the protection levels of two adjacent cabinet cavities 31 are different, the protection level of the cabinet cavity 31 in communication with the inner cavity of the duct body 21 is no lower than the protection level of the other cabinet cavity 31. Because the connection between the electrical connector 4 and the terminal block 11 is located within the inner cavity of the duct body 21, when the protection levels of two adjacent cabinet cavities 31 are different, designing the connection between the electrical connector 4 and the terminal block 11 in the cabinet cavity 31 with a relatively high or even higher protection level can avoid potential problems such as increased contact resistance due to corrosion at the joint between the terminal block 11 and the electrical connector 4, thereby improving the reliability of the electrical connection.

[0087] It should also be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

[0088] As used in this application and the claims, unless the context clearly indicates an exception, the terms "a," "an," "an," and / or "the" are not intended to refer to the singular and may include the plural, unless the context clearly indicates otherwise. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements. The phrase "comprises a..." does not preclude the presence of additional identical elements in the process, method, product, or apparatus that includes the elements.
