Description

Technical Field

[0001] The utility model relates to the technical field of smart grid equipment, and in particular to a shell structure of a smart grid fusion terminal, a fusion terminal and a terminal component. Background Art

[0002] Grid intelligent converged terminals (also known as converged terminals or smart converged terminals) are essential devices in smart distribution networks. Typically installed within distribution substations, these integrated, multifunctional, and intelligent edge devices differ from concentrators, feeder terminals, dedicated transformer terminals, and distribution transformer terminals primarily in that they are based on a unified hardware and software platform with powerful edge computing, data storage, communication, and data security capabilities, providing functional expansion and adaptability for specific use cases. The use of grid intelligent converged terminals enables comprehensive perception of distribution substation information, intelligent business processing, and precise execution of control commands. This effectively supports the development of distribution networks towards digitalization, intelligence, and interactivity, and is crucial for building a safe, reliable, efficient, and green modern distribution network.

[0003] In existing applications, the main functions of the power grid intelligent fusion terminal include multi-type power grid data collection, data edge computing and processing, power grid protection and control, network communication support, etc. At the same time, in different application scenarios, the power grid intelligent fusion terminal realizes its functions based on its high platform function openness and scalability. The implementation means is to flexibly connect various expansion modules through reserved standard interfaces or slots to meet the differentiated needs of different application scenarios and different substations. Regarding the configuration method of the expansion module on the fusion terminal, the conventional configuration method is such as the technical solution provided by the patent application number CN202221037831.2 and the invention name of a substation intelligent fusion terminal, which provides a sunken cavity structure on the outer shell as the installation cavity for the expansion module, and is generally used to also include a cover plate connected to the outer shell, and the cover plate is used to cover the installation cavity and provide support for the outer end of the expansion module therein.

[0004] In existing applications, power grid intelligent fusion terminals are generally installed in a box structure, which is used to provide the fusion terminal with environmental protection functions such as dustproof, waterproof, and joint corrosion protection. At the same time, the main structure of the fusion terminal is generally provided with dustproof and waterproof functions. In view of the application environment of the fusion terminal, it is necessary to further optimize the structure of the fusion terminal to improve its reliability during use. Utility Model Content

[0005] The purpose of the utility model is to provide a power grid intelligent fusion terminal shell structure, a fusion terminal and a terminal component, which are used to optimize the waterproof performance of the expansion module and achieve the purpose of improving the reliability of the fusion terminal during use.

[0006] The purpose of the utility model is mainly achieved through the following technical solutions: a power grid intelligent fusion terminal shell structure, including a shell body, a module cavity for installing an expansion module is provided on the surface of the shell body, and a cover plate for covering the module cavity, a horizontal bar and a vertical bar are provided on the surface of the shell body, and the left and right sides of the horizontal bar are both provided with vertical bars, and the upper ends of the vertical bars are connected to the ends of the horizontal bars, and the horizontal bars and the vertical bars are both rib structures protruding relative to the surface of the shell body or are both grooves on the surface of the shell body;

[0007] The module cavity is located within the area surrounded by the horizontal bars and the vertical bars;

[0008] The top side, left side and right side of the cover plate all have folded edges;

[0009] When the cover plate covers the module cavity, the cover plate cooperates with the housing body as follows:

[0010] When both the horizontal bars and the vertical bars are rib structures protruding relative to the surface of the shell body, the folded edge of the cover plate is buckled onto the outer side of the rib structure;

[0011] When the horizontal bars and the vertical bars are both grooves on the surface of the shell body, the folded edges of the cover plate are embedded in the grooves.

[0012] In the prior art, the power grid intelligent fusion terminal is configured to include a shell structure, and a mainboard module integrating functional modules such as a processor unit, a storage unit, a current detection unit, a voltage detection unit, a power detection unit, and a communication unit is installed in the shell structure. In order to adapt to the differentiated functional requirements of the power grid intelligent fusion terminal under different applications, the shell structure is provided with a module cavity for installing an extension module. In specific applications, the installation of the extension module on the fusion terminal is completed through the interface module serving as a serial port interface in the module cavity, and a cover plate is used to cover the module cavity. In specific applications, the fusion terminal is used to be installed in a terminal box to avoid adverse effects such as rainfall and sunlight on the fusion terminal. At the same time, since the fusion terminal is a heat source in the terminal box when working, the terminal box is required to have good heat dissipation capabilities. Common terminal box settings include the use of thin shell boxes. Under such applications, possible problems include: after the ambient temperature drops, condensation occurs on the inner wall of the terminal box. The shell body is generally configured to have good sealing capabilities. However, the existing cover plate is generally set as a flat structure. In this way, the cover plate in the closed state is only attached to the surface of the shell body. When the water generated by condensation drips onto the shell body above the fusion terminal cover plate, the water body easily flows into the module cavity through the gap between the cover plate and the shell body. Under the hot environment of the module cavity, the ambient humidity in the module cavity increases. It is even possible that water will pass through the gap between the expansion module and the bottom surface of the module cavity and directly infiltrate the interface position of the serial port module, affecting the reliability of the fusion terminal during use.

[0013] Based on the above problems, this solution provides a technical solution to solve the problem of condensation affecting the connection reliability between the expansion module and the serial port module by setting the cover plate with a folded edge and providing horizontal and vertical bars on the shell body located outside the module cavity. Specifically:

[0014] The implementation methods of the horizontal and vertical bars include both being rib structures or both being trough bodies. When it is a rib structure, the cover plate in a buckled state is a folded edge that is buckled onto the outer side of the rib structure. In this way, the horizontal bars, vertical bars and folded edges form a water baffle located on the top, left and right sides of the module cavity. When condensation drips, the corresponding side folds of the cover plate and the matching relationship formed by the horizontal and vertical bars can effectively prevent water droplets from entering the module cavity, thereby achieving the purpose of moisture-proofing the interior of the module cavity; when it is a trough structure, the same as above, the trough body and the folded edge form an enclosure located on the periphery of the module cavity, and also form a water retaining structure that effectively prevents water droplets from entering the module cavity, thereby achieving the purpose of preventing condensation water droplets from entering the module cavity.

[0015] At the same time, in this solution, the horizontal bars and vertical bars can be formed on the shell body at one time during the injection molding process of the shell body and the cover plate (the existing shell body is generally a plastic shell, and the cover plate is generally a translucent plastic plate). This solution has the characteristic of convenient processing; the existing cover plate is generally installed on the shell body in a rotating opening and closing manner. The matching relationship between the above horizontal bars, vertical bars and folded edges does not affect the operating method of the cover plate rotating opening and closing.

[0016] In a specific embodiment, a hanging plate for realizing the installation of a fusion terminal is provided at the upper end of the back side of the shell body, and the module cavity is provided in the lower area of ​​the front end face of the shell body (the upper area of ​​the front end face of the shell body is the light guide column setting area, the display part setting area and the operation part setting area). When the fusion terminal is installed, the horizontal bars extend in the horizontal direction and the vertical bars extend in the vertical direction. In this application, when condensation drops onto the top surface, upper area or side area of ​​the shell body, the downward flowing water can be effectively blocked by the horizontal bars, vertical bars and folded edges to avoid entering the module cavity.

[0017] As a person skilled in the art, the above horizontal bars, vertical bars and folded edges form a water retaining structure on the upper part and left and right sides of the module cavity. Water droplets have the characteristic of flowing downward along the shell body and having the opportunity to enter the module cavity. This scheme is not set to have a sealing structure between the edge of the cover plate and the shell body. In all implementation forms of the above scheme, water still has the possibility of crossing the horizontal bars and the folded edges on the top side of the cover plate and entering the module cavity. However, even under these implementation forms, since the amount of water droplets generated by condensation is affected by the internal temperature of the terminal box, the size of the space, the external temperature, etc., the amount of water condensed will not be large. The cover plate with folded edges and the shell body with horizontal bars and vertical bars still have good moisture-proof performance of the module cavity compared to the cover plate with a flat structure that is directly attached to the outer surface of the shell body.

[0018] As a further technical solution for the shell structure of the power grid intelligent fusion terminal:

[0019] The module cavity is a semi-open cavity structure with cavity walls on the top, left and right sides and an open bottom;

[0020] The horizontal bars and vertical bars are both rib structures protruding relative to the surface of the shell body;

[0021] The upper surface of the horizontal bar is provided with grooves extending to both ends of the horizontal bar.

[0022] The above scheme provides a specific implementation form of the module cavity, and the semi-open cavity structure is that the top and left and right sides of the module cavity have side walls, and the lower side is open to form a breathable channel between the module cavity and the outside world, which is used to avoid the formation of a high humidity environment inside the closed module cavity and is conducive to the heat dissipation of the module cavity; the horizontal bars and vertical bars of the rib structure are used to adapt to the general thickness of the shell body, that is, there is no need to increase the local thickness of the shell body to set up the groove body; the groove is used to receive water from above the horizontal bar and guide the water to the outside of the vertical bar and drip to the outside of the shell body, so as to avoid the water flowing over the horizontal bar into the module cavity.

[0023] Of the left and right ends of the cover plate, one end is flipped and connected to the shell body through a connecting seat, and the other end is provided with a locking screw for pressing the cover plate onto the shell body.

[0024] The above solution provides a specific method for installing the cover on the housing body, specifically providing a housing structure in which the cover is rotated on the housing body to open and close. Preferably, to facilitate opening and closing of the cover, the locking screw adopts a locking screw with a butterfly nut fixed on the stud.

[0025] The folded edge on the top side of the cover plate has a top surface that is a slope, and the top of the slope is located at one end of the folded edge close to the shell body.

[0026] The above solution provides a specific implementation of a cover plate. The sloped surface is used to guide water flowing from above the top surface of the cover plate toward the outer surface of the cover plate, thereby reducing the amount of water flowing into the inner side of the hem. In practice, due to the gap between the hem end surface and the main body of the housing, to completely prevent condensation from affecting the internal environment of the module cavity, it is preferred to adopt an implementation method in which the cover plate has a sloped surface and the upper surface of the horizontal strip has grooves.

[0027] It also includes a plurality of serial port modules configured on the bottom surface of the module cavity, the serial port modules serving as serial port interfaces for connecting expansion modules in the module cavity;

[0028] Each serial port module is configured with an annular gasket fixed on the bottom surface and protruding relative to the bottom surface, and the serial port module is located within an area surrounded by the annular gasket.

[0029] The above solution provides a technical solution for providing secondary moisture-proof protection for the serial port module in the module cavity. Specifically, based on the installation characteristics of the expansion module being plugged into the serial port module, this solution provides an annular gasket located on the bottom surface of the module cavity on the periphery of the serial port module. When the expansion module is plugged into the serial port module, the annular gasket is squeezed between the bottom surface of the module cavity and the bottom surface of the expansion module, thereby forming an isolation ring located on the outer periphery of the serial port module, thereby achieving the purpose of preventing air humidity and direct water from affecting the life and reliability of the serial port module.

[0030] The annular gasket is configured to be installed on the bottom surface of the module cavity through the annular groove of the bottom surface.

[0031] The above provides a specific installation method of an annular gasket on the bottom surface of the module cavity, specifically: there is an annular groove on the bottom surface of the module cavity, and the inner side of the annular gasket is embedded in the annular groove. This method can not only constrain the position of the annular gasket relative to the serial port module, but also has a simple structure and is convenient for maintaining the secondary moisture-proof structure of the serial port module by replacing the annular gasket.

[0032] The present solution also relates to a power grid intelligent fusion terminal, comprising a shell, wherein the shell is the power grid intelligent fusion terminal shell structure as described in any one of the above items.

[0033] The above-provided intelligent power grid fusion terminal is a fusion terminal adopting the intelligent fusion terminal shell structure.

[0034] As a further technical solution for the power grid intelligent fusion terminal:

[0035] The module further comprises an expansion module installed in the module cavity. When the cover plate covers the module cavity, the expansion module is supported on the inner wall surface of the cover plate.

[0036] The above solution provides a specific form of cooperation between the expansion module and the cover plate. With this solution, the cover plate supports the expansion module and constrains the relative position of the expansion module and the serial port module, thereby preventing the connection relationship between the serial port module and the expansion module from failing and ensuring the reliability of the connection between the expansion module and the serial port module. Furthermore, for the use of an annular gasket, the support force of the cover plate on the expansion module is used to maintain the contact force between the annular gasket and the bottom surface of the expansion module and the bottom surface of the module cavity, thereby effectively providing secondary protection for the serial port module.

[0037] The present solution also relates to a power grid intelligent terminal assembly, comprising a power grid intelligent fusion terminal and a terminal box, wherein the power grid intelligent fusion terminal is installed in the terminal box, and the power grid intelligent fusion terminal is the power grid intelligent fusion terminal as described in any one of the above items.

[0038] The above-provided grid intelligent terminal components include the grid intelligent fusion terminal, which is a specific application of the grid intelligent fusion terminal on the smart grid.

[0039] As a further technical solution for the power grid intelligent terminal component:

[0040] The box wall of the terminal box is a metal plate, and the inner wall of the top surface of the terminal box is provided with a heat-insulating layer.

[0041] The above further limits the structural form of the terminal box. The metal plate terminal box is used to enhance the heat dissipation capacity of the opposite side space inside it. The above insulation layer is used to prevent condensation on the inner wall of its top surface, so as to avoid water dripping from the top of the terminal box and affecting the reliability of the fusion terminal.

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0043] This solution provides a technical solution that solves the problem of condensation affecting the connection reliability between the expansion module and the serial port module and improves the reliability of the integrated terminal during use by providing a cover with a folded edge and providing horizontal and vertical bars on the shell body located on the periphery of the module cavity.

[0051] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0052] Example 1:

[0053] like Figure 1-4 As shown, an embodiment of the present utility model provides a power grid intelligent fusion terminal shell structure, including a shell body 1, a module cavity 4 for installing an expansion module 3 is provided on the surface of the shell body 1, and a cover plate 2 for covering the module cavity 4. The surface of the shell body 1 is provided with horizontal bars 5 and vertical bars 6. The left and right sides of the horizontal bars 5 are both provided with vertical bars 6. The upper ends of the vertical bars 6 are connected to the ends of the horizontal bars 5. The horizontal bars 5 and the vertical bars 6 are both rib structures protruding relative to the surface of the shell body 1 or are both grooves on the surface of the shell body 1.

[0054] The module cavity 4 is located within the area enclosed by the horizontal bars 5 and the vertical bars 6;

[0055] The top, left and right sides of the cover plate 2 are provided with folded edges 10;

[0056] When the cover plate 2 covers the module cavity 4, the cover plate 2 cooperates with the housing body 1 as follows:

[0057] When the horizontal bars 5 and the vertical bars 6 are both rib structures protruding relative to the surface of the shell body 1, the folded edge 10 of the cover plate 2 is buckled onto the outer side of the rib structure;

[0058] When the horizontal bars 5 and the vertical bars 6 are both grooves on the surface of the shell body 1 , the folded edge 10 of the cover plate 2 is embedded in the grooves.

[0059] In the prior art, the power grid intelligent fusion terminal is configured to include a shell structure, and a mainboard module integrating functional modules such as a processor unit, a storage unit, a current detection unit, a voltage detection unit, a power detection unit, and a communication unit is installed in the shell structure. In order to adapt to the differentiated functional requirements of the power grid intelligent fusion terminal under different applications, the shell structure is provided with a module cavity 4 for installing the extension module 3. In specific applications, the installation of the extension module 3 on the fusion terminal is completed through the interface module serving as the serial port interface in the module cavity 4, and the cover plate 2 is used to cover the module cavity 4. In specific applications, the fusion terminal is used to be installed in the terminal box to avoid adverse effects such as rainfall and sunlight on the fusion terminal. At the same time, since the fusion terminal is the heat source in the terminal box when working, the terminal box is required to have good heat dissipation capabilities. The commonly used configuration of the terminal box includes the use of a thin shell box. Under such an application, possible problems include: after the ambient temperature drops, condensation occurs on the inner wall of the terminal box. The shell body 1 is generally configured to have good sealing capabilities. However, the existing cover plate 2 is generally set to a flat plate structure. In this way, the cover plate 2 in the closed state is only attached to the surface of the shell body 1, and at the same time, it is not attached to the shell body 1. The cover plate 2 is different from the body main body 1. The cover plate 2 is opened and closed as needed during the use of the fusion terminal to configure the expansion module therein as needed. The installation characteristics and use characteristics of the above cover plate 2 result in that when the water generated by condensation drips onto the shell main body 1 above the cover plate 2 of the fusion terminal, the water can easily flow into the module cavity 4 through the gap between the cover plate 2 and the shell main body 1. Under the hot environment of the module cavity 4, the ambient humidity in the module cavity 4 increases, and it is even possible that water passes through the gap between the expansion module 3 and the bottom of the module cavity 4 and directly infiltrates the interface position of the serial port module 12, affecting the reliability of the fusion terminal during use.

[0060] Based on the above problems, this solution provides a technical solution to solve the problem of condensation affecting the connection reliability between the expansion module 3 and the serial port module 12 by providing the cover plate 2 with a folded edge 10 and providing a horizontal bar 5 and a vertical bar 6 on the housing body 1 located outside the module cavity 4. Specifically:

[0061] The implementation methods of the horizontal bars 5 and the vertical bars 6 include both being rib structures or both being trough bodies. When it is a rib structure, the cover plate 2 in a buckled state is a folded edge 10 that is buckled on the outside of the rib structure. In this way, the horizontal bars 5, vertical bars 6 and folded edges 10 form a water baffle located on the top, left and right sides of the module cavity 4. When condensation drips, the corresponding side folded edges 10 of the cover plate 2 and the matching relationship formed by the horizontal bars 5 and the vertical bars 6 can effectively prevent water droplets from entering the module cavity 4, thereby achieving the purpose of moisture-proofing the interior of the module cavity 4; when it is a trough structure, the same as above, the trough body and the folded edge 10 form a barrier located on the periphery of the module cavity 4, and also form a water retaining structure that effectively prevents water droplets from entering the module cavity 4, thereby achieving the purpose of preventing condensation water droplets from entering the module cavity 4.

[0062] At the same time, in this solution, the horizontal bars 5 and the vertical bars 6 can be formed on the shell body 1 at one time during the injection molding process of the shell body 1 and the injection molding process of the cover plate 2 (the existing shell body 1 is generally a plastic shell, and the cover plate 2 is generally a translucent plastic plate). This solution has the characteristic of convenient processing; the existing cover plate 2 is generally installed on the shell body 1 in a rotating opening and closing manner. The above-mentioned horizontal bars 5, vertical bars 6 and folding edge 10 have a matching relationship that does not affect the operation mode of the cover plate 2 rotating opening and closing.

[0063] In a specific embodiment, a hanging plate for realizing the installation of a fusion terminal is provided at the upper end of the back side of the shell body 1, and the module cavity 4 is provided in the lower area of ​​the front end face of the shell body 1 (the upper area of ​​the front end face of the shell body 1 is the light guide column setting area, the display part setting area and the operation part setting area). When the fusion terminal is installed, the horizontal bar 5 extends in the horizontal direction and the vertical bar 6 extends in the vertical direction. In this application, when condensation drops onto the top surface, upper area or side area of ​​the shell body 1, the downward flowing water can be effectively blocked by the horizontal bar 5, the vertical bar 6 and the folded edge 10 to avoid entering the module cavity 4.

[0064] As a person skilled in the art, the above horizontal bars 5, vertical bars 6 and folded edges 10 form a water retaining structure on the upper part and left and right sides of the module cavity 4. Water droplets have the characteristic of flowing downward along the shell body 1 and having the opportunity to enter the module cavity 4. This scheme is not set to have a sealing structure between the edge of the cover plate 2 and the shell body 1. In all implementation forms of the above scheme, water still has the possibility of entering the module cavity 4 over the horizontal bars 5 and the folded edges 10 on the top side of the cover plate 2. However, even in these implementation forms, since the amount of water droplets generated by condensation is affected by the internal temperature of the terminal box, the size of the space, the external temperature, etc., the amount of water condensed will not be large. The cover plate 2 with folded edges 10 and the shell body 1 with horizontal bars 5 and vertical bars 6 still have good moisture-proof performance of the module cavity 4 compared to the cover plate 2 with a flat structure that directly fits the outer surface of the shell body 1.

[0065] In this embodiment, Figure 1 It shows a schematic diagram of the fusion terminal structure in which the complete cover plate 2 covers the module cavity 4. Figure 2 Only the left side of the cover 2 is retained. Figure 2 as well as Figure 4 The horizontal bars 5 and vertical bars 6 are all implemented in a ribbed structure. Figure 3 This is a method in which the horizontal bar 5 adopts a rib structure, and the rib structure is a strip-shaped rib formed on the surface of the shell body 1.

[0066] Example 2:

[0067] This embodiment is further refined based on the embodiment 1:

[0068] The module cavity 4 is a semi-open cavity structure with cavity walls on the top, left and right sides and an open bottom.

[0069] The horizontal bars 5 and vertical bars 6 are both rib structures protruding relative to the surface of the shell body 1;

[0070] The upper surface of the horizontal bar 5 is provided with grooves 7 extending to both ends of the horizontal bar 5 .

[0071] The above scheme provides a specific implementation form of the module cavity 4, and the semi-open cavity structure is that the top and left and right sides of the module cavity 4 have side walls, and the lower side is open to form a breathable channel between the module cavity 4 and the outside world, which is used to avoid the formation of a high humidity environment inside the closed module cavity 4 and is conducive to heat dissipation of the module cavity 4; the horizontal bars 5 and vertical bars 6 of the rib structure are used to adapt to the general thickness of the shell body 1, that is, there is no need to increase the local thickness of the shell body 1 to set up the trough body; the groove 7 is used to receive water from above the horizontal bar 5 and divert the water to the outside of the vertical bar 6 and drip to the outside of the shell body 1, to prevent the water from flowing over the horizontal bar 5 and into the module cavity 4.

[0072] Example 3:

[0073] This embodiment is further refined based on the embodiment 1:

[0074] Of the left and right ends of the cover plate 2 , one end is flipped and connected to the shell body 1 through a connecting seat 9 , and the other end is provided with a locking screw 8 for pressing the cover plate 2 onto the shell body 1 .

[0075] The above solution provides a specific method for mounting the cover plate 2 on the housing body 1, specifically providing a housing structure in which the cover plate 2 is opened and closed by rotation on the housing body 1. Preferably, to facilitate opening and closing of the cover plate 2, the locking screw 8 is a locking screw 8 having a butterfly nut fixed on a stud.

[0076] Example 4:

[0077] This embodiment is further refined based on the embodiment 1:

[0078] The folded edge 10 on the top side of the cover plate 2 has a top surface that is a slope, and the top of the slope is located at one end of the folded edge 10 close to the shell body 1.

[0079] The above solution provides a specific implementation of the cover plate 2. The above slope is used to: for water flowing from above the top surface of the cover plate 2, the slope guides the water to the outer surface of the cover plate 2 by diverting it, thereby reducing the amount of water flowing into the inner side of the fold 10. In actual use, due to the gap between the end surface of the fold 10 and the shell body 1, in order to completely prevent condensation from affecting the internal environment of the module cavity 4, it is preferred to adopt the above implementation method of having a slope on the cover plate 2 and grooves 7 on the upper surface of the horizontal bar 5.

[0080] Example 5:

[0081] This embodiment is further refined based on the embodiment 1:

[0082] It also includes a plurality of serial port modules 12 configured on the bottom surface of the module cavity 4, and the serial port modules 12 serve as serial port interfaces for connecting the expansion modules 3 in the module cavity 4;

[0083] Each serial port module 12 is configured with an annular gasket 11 fixed on the bottom surface and protruding relative to the bottom surface. The serial port module 12 is located within the area enclosed by the annular gasket 11 .

[0084] The above scheme provides a technical solution for providing secondary moisture-proof protection for the serial port module 12 in the module cavity 4. Specifically, this scheme is based on the installation characteristics of the expansion module 3 being plugged into the serial port module 12, and provides an annular gasket 11 located on the bottom surface of the module cavity 4 on the periphery of the serial port module 12. When the expansion module 3 is plugged into the serial port module 12, the annular gasket 11 is squeezed between the bottom surface of the module cavity 4 and the bottom surface of the expansion module 3, thereby forming an isolation ring located on the outer periphery of the serial port module 12, thereby achieving the purpose of preventing air humidity and direct water from affecting the life and reliability of the serial port module 12.

[0085] Example 6:

[0086] This embodiment is further refined based on embodiment 5:

[0087] The annular gasket 11 is configured to be installed on the bottom surface of the module cavity 4 through the annular groove of the bottom surface.

[0088] The above provides a specific installation method of the annular gasket 11 on the bottom surface of the module cavity 4, specifically: there is an annular groove on the bottom surface of the module cavity 4, and the inner side of the annular gasket 11 is embedded in the annular groove. This method can not only constrain the position of the annular gasket 11 relative to the serial port module 12, but also has a simple structure and is convenient for maintaining the secondary moisture-proof structure of the serial port module 12 by replacing the annular gasket 11.

[0089] Example 7:

[0090] Based on Example 1, this embodiment provides a power grid intelligent fusion terminal, including a shell. The shell is the power grid intelligent fusion terminal shell structure described in Example 1.

[0091] The above-provided intelligent power grid fusion terminal is a fusion terminal adopting the intelligent fusion terminal shell structure.

[0092] Example 8:

[0093] This embodiment is further refined based on embodiment 7:

[0094] The module cavity 4 further includes an expansion module 3 installed in the module cavity 4 . When the cover plate 2 covers the module cavity 4 , the expansion module 3 is supported on the inner wall surface of the cover plate 2 .

[0095] The above scheme provides a specific form of cooperation between the expansion module 3 and the cover plate 2. With the above scheme, the cover plate 2 supports the expansion module 3 and constrains the relative position of the expansion module 3 and the serial port module 12, thereby preventing the connection relationship between the serial port module 12 and the expansion module 3 from failing and ensuring the reliability of the connection between the expansion module 3 and the serial port module 12. Furthermore, for the use of the annular gasket 11, the supporting force of the cover plate 2 on the expansion module 3 is used to maintain the contact force between the annular gasket 11 and the bottom surface of the expansion module 3 and the bottom surface of the module cavity 4, thereby effectively providing secondary protection for the serial port module 12.

[0096] Example 9:

[0097] Based on Example 7, this embodiment provides a power grid intelligent terminal component, including a power grid intelligent fusion terminal and a terminal box. The power grid intelligent fusion terminal is installed in the terminal box. The power grid intelligent fusion terminal is the power grid intelligent fusion terminal described in Example 7.

[0098] The above-provided grid intelligent terminal components include the grid intelligent fusion terminal, which is a specific application of the grid intelligent fusion terminal on the smart grid.

[0099] Example 10:

[0100] This embodiment is further refined based on embodiment 9:

[0101] The box wall of the terminal box is a metal plate, and the inner wall of the top surface of the terminal box is provided with a heat-insulating layer.

[0102] The above further limits the structural form of the terminal box. The metal plate terminal box is used to enhance the heat dissipation capacity of the opposite side space inside it. The above insulation layer is used to prevent condensation on the inner wall of its top surface, so as to avoid water dripping from the top of the terminal box and affecting the reliability of the fusion terminal.
