Description

Technical Field

[0001] This application relates to the field of electricity meter technology, and in particular to an elastic sealing cover and an electricity meter. Background Technology

[0002] A multi-user electricity meter is a device used to simultaneously measure and record the electricity consumption of multiple independent users. It is widely used in apartment buildings, commercial buildings, industrial facilities, and other scenarios, enabling accurate metering and management of each user's electricity consumption. With the development and popularization of smart grids, multi-user electricity meters have been widely applied in power systems.

[0003] Multi-user energy meters typically include multiple slave units (i.e., energy meters) and a master unit (i.e., controller). The multiple slave units are connected to the master unit for data transmission, and the master unit can manage the multiple slave units.

[0004] In related technologies, an electrical connection structure is installed inside the casing of the slave device, and an opening is made on the casing to expose the electrical connection structure, which facilitates electrical connection between slave devices. However, when no other slave device is connected to the opening, the opening compromises the sealing of the slave device in question. Utility Model Content

[0005] This application provides an elastic sealing cover and an electricity meter, which aims to improve the sealing performance of the electricity meter, prevent foreign objects from entering the inside of the electricity meter, and thus improve the performance of the electricity meter.

[0006] The technical solution of this application is as follows:

[0007] In a first aspect, this application provides an elastic sealing cover for use in an electricity meter. The elastic sealing cover includes a sealing part, a connecting part, and a first snap-fit ​​part. The connecting part is disposed on one side of the sealing part and connected to the sealing part. Along the direction from the connecting part to the sealing part, the projection of the connecting part falls within the projection of the sealing part. The first snap-fit ​​part is disposed along the edge of the connecting part, and a snap-fit ​​groove is formed between the first snap-fit ​​part and the sealing part.

[0008] Based on the elastic sealing cap provided in the first aspect, when in use, the elastic sealing cap needs to be squeezed by external force to deform the first snap-fit ​​part so that it can enter the interior of the opening, and the snap-fit ​​groove can snap into the opening, and the sealing part covers the opening part. In this way, the elastic sealing part can achieve the function of sealing the opening.

[0009] Secondly, based on the same inventive concept, this application also provides an electricity meter, which includes a casing, an electrical connection structure, and an elastic sealing cover: an opening is provided on the casing wall of the casing; the electrical connection structure is located inside the casing, and the opening exposes the electrical connection structure; the elastic sealing cover is the aforementioned elastic sealing cover, the elastic sealing cover is disposed at the opening, the sealing part covers the opening, and the snap-fit ​​groove snaps into the casing wall at the opening.

[0010] Based on the electricity meter provided in the second aspect, the opening of the electricity meter is provided with the elastic sealing cover provided in the first aspect. The elastic sealing cover can be fixed to the opening of the electricity meter by compression deformation. In this way, the elastic sealing cover can seal the opening, thereby preventing foreign objects from entering the electricity meter through the opening, which helps to ensure the working stability of the electricity meter and improve the performance of the electricity meter.

[0011] In one possible design, the resilient sealing cap further includes a second snap-fit ​​portion, which is disposed on the side of the connecting portion away from the sealing portion, and the end of the second snap-fit ​​portion away from the connecting portion is provided with a snap-fit ​​interface.

[0012] Based on the elastic sealing cap provided by this embodiment, the elastic sealing cap has a second snap-fit ​​portion. Thus, when the elastic sealing cap is used to seal an opening, the elastic sealing portion can not only be fixed to the opening by the first snap-fit ​​portion, but also snap-fit ​​with the opening or other components inside the opening by the second snap-fit ​​portion. Thus, the elastic sealing cap is not easy to loosen and has good stability.

[0013] Based on the aforementioned elastic cover, in the energy meter structure, the end of the electrical connection structure facing the opening is embedded in the card interface, and the outer periphery of the electrical connection structure is in contact with the inner wall of the card interface.

[0014] Based on the energy meter provided by this embodiment, a second snap-fit ​​portion is provided on the side of the connecting portion away from the sealing portion, and a snap-fit ​​interface is provided at the end of the second snap-fit ​​portion away from the connecting portion. When the elastic sealing cover is installed at the opening of the energy meter, the end of the electrical connection structure located inside the meter casing facing the opening can be embedded into the snap-fit ​​interface, and the outer periphery of the electrical connection structure contacts the inner wall of the snap-fit ​​interface. Thus, the electrical connection structure can also support and flatten the elastic sealing cover, allowing the elastic sealing cover to be more stably installed at the opening, resulting in a more stable sealing effect and a more aesthetically pleasing appearance.

[0015] In one possible design, the end of the card interface is provided with a chamfer to facilitate card insertion. This facilitates the installation of the resilient sealing cap.

[0016] In one possible design, the end of the card interface is provided with a chamfer to facilitate the installation of the electrical connection structure.

[0017] Based on the energy meter provided by this embodiment, when the elastic sealing cover is installed, the end of the electrical connection structure facing the opening will be embedded in the card interface, and the outer periphery of the electrical connection structure will contact the inner wall of the card interface. A chamfer is provided at the end of the card interface, so that the electrical connection structure is easier to snap into the card interface, and the installation of the elastic sealing cover will be easier.

[0018] In one possible implementation, the opening includes a large end and a small end connected together, the large end being the portion of the opening near the outside of the watch case;

[0019] The sealing part is embedded in the large end, the connecting part is embedded in the small end, the snap-fit ​​groove is snapped into the shell wall at the small end, and the surface of the sealing part away from the connecting part is flush with the outer surface of the shell wall at the opening of the watch case.

[0020] Based on the electricity meter provided by this embodiment, the surface of the sealing part away from the connecting part is flush with the outer surface of the shell wall where the opening is located on the meter casing. In this way, the elastic sealing cover is not easy to fall off due to scratches, and the outer surface of the electricity meter will be smoother.

[0021] In one possible design, the surface of the case is further provided with a groove, which communicates with the large end.

[0022] Based on the electricity meter provided by this embodiment, a groove communicating with the large end is provided on the surface of the meter casing. The groove provides operating space for the removal of the elastic sealing cover. In this way, the user can tear the elastic sealing cover at the groove to facilitate the removal of the sealing cover.

[0023] In one possible design, a component identifier is provided on the side of the sealing portion away from the connecting portion. Based on the resilient sealing cap provided by this embodiment, the component identifier helps the user identify the component at the resilient sealing cap.

[0024] In one possible design, the component is identified as the identifier of the electrical connection structure.

[0025] When the energy meter provided by this embodiment is used as a slave unit of a multi-user energy meter, multiple slave units need to be assembled. A component mark of the electrical connection structure is set on the side of the sealing part away from the connection part. In this way, the user can quickly determine the location of the electrical connection structure, which helps to improve the assembly efficiency of the multi-user energy meter.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and drawings of this application are intended to cover non-exclusive inclusion.

[0047] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0048] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the electricity meter of this application. For example, in the description of this application, the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0050] The following section provides a detailed description of this application, starting from its background and with reference to the accompanying drawings.

[0051] Figure 1 The diagram shown is a structural schematic of a multi-user energy meter provided by related technologies. Figure 2 The diagram shown is a structural schematic of one of the energy meters (slave unit) in a multi-user energy meter system provided by related technologies. Figure 3 for Figure 2 The diagram shows the structure of the electricity meter from another perspective.

[0052] Please combine Figure 1 , Figure 2 and Figure 3 In related technologies, multi-user energy meters typically include a master unit A and multiple slave units B. The master unit A has an electrical connection structure on one side for connecting to the slave units B, and the slave units B have electrical connection structures on opposite sides. One side has a pin B2 as the electrical connection structure, and the other side has a socket B3 as the electrical connection structure. Thus, the master unit A and the multiple slave units B can be arranged sequentially, and adjacent master units A and slave units B, as well as slave units B, can be electrically connected through mutually cooperating electrical connection structures.

[0053] Please continue to refer to this. Figures 1 to 3 In some cases, the electrical connection structure on one side of slave device B is recessed relative to the side of the watch case 12, while the electrical connection structure on the other side of slave device B protrudes relative to the side of the watch case 12. A corresponding opening B1 is provided on the watch case 12 at the location of the recessed electrical connection structure. Thus, when two adjacent slave devices B are electrically connected, the electrical connection structure on one slave device B that protrudes relative to the watch case 12 will be inserted into the electrical connection structure on the other slave device B that is recessed relative to the watch case 12, thereby realizing the electrical connection between two adjacent slave devices B, and the distance between two adjacent slave devices B will be smaller.

[0054] However, in some cases, the opening B1 of slave unit B located at the end of the multi-user energy meter does not need to be connected to other slave units B. In this case, the opening B1 will affect the sealing performance of the slave unit B. Foreign objects can easily enter the slave unit B through the opening B1, thereby affecting the performance of the slave unit B itself, and thus affecting the overall performance of the multi-user energy meter.

[0055] Considering the sealing performance of electricity meters, this application provides an elastic sealing cover for electricity meters. Figure 4 This is a schematic diagram of a structure of the elastic sealing cap provided in an embodiment of this application. Figure 5 for Figure 4 A side view of the resilient sealing cap shown.

[0056] Please refer to Figure 4 and Figure 5The elastic sealing cap 11 provided in this application includes a sealing portion 111, a connecting portion 112, and a first snap-fit ​​portion 113. The connecting portion 112 is disposed on one side of the sealing portion 111 and connected to the sealing portion 111. Along the direction from the connecting portion 112 to the sealing portion 111, the projection of the connecting portion 112 falls within the projection of the sealing portion 111. The first snap-fit ​​portion 113 is disposed along the edge of the connecting portion 112, and a snap-fit ​​groove 1131 is formed between the first snap-fit ​​portion 113 and the sealing portion 111.

[0057] It is understandable that the resilient sealing cap 11 is a sealing element with elastic deformation capability. The material of the resilient sealing cap 11 can be selected as rubber with good elasticity and sealing performance.

[0058] When in use, the elastic sealing cover 11 needs to be squeezed by external force to deform the first snap-fit ​​part 113 so that it can enter the interior of the opening, and the snap-fit ​​groove 1131 can snap into the opening. The sealing part 111 covers the opening, so the elastic sealing part 111 can achieve the function of sealing the opening.

[0059] Based on the same inventive concept, this application also provides an electricity meter 1 using the aforementioned elastic sealing cover 11. Figure 6 This is a schematic diagram of the structure of an electricity meter provided in an embodiment of this application. Figure 7 for Figure 6 Exploded view.

[0060] Please combine Figure 6 and Figure 7 The electricity meter 1 provided in this application includes a meter housing 12, an electrical connection structure 13, and an elastic sealing cover 11. An opening 121 is provided on the wall of the meter housing 12. The electrical connection structure 13 is located inside the meter housing 12, and the opening 121 exposes the electrical connection structure 13.

[0061] Please combine Figure 4 and Figure 5 The elastic sealing cap 11 includes a sealing portion 111, a connecting portion 112, and a first snap-fit ​​portion 113. The connecting portion 112 is disposed on one side of the sealing portion 111 and is connected to the sealing portion 111. Along the direction from the connecting portion 112 to the sealing portion 111, the projection of the connecting portion 112 falls within the projection of the sealing portion 111. The first snap-fit ​​portion 113 is disposed along the edge of the connecting portion 112, and a snap-fit ​​groove 1131 is formed between the first snap-fit ​​portion 113 and the sealing portion 111.

[0062] Please combine Figures 4 to 7 An elastic sealing cover 11 is provided at the opening 121, the sealing part 111 covers the opening 121, and the snap-fit ​​groove 1131 at the opening 121 snaps into the shell wall at the opening 121.

[0063] Specifically, please combine Figure 4 , Figure 5and Figure 7 When the elastic sealing cover 11 is installed, the first snap-fit ​​part 113 will deform under the pressure of external force and can enter the inside of the watch case 12 through the opening 121, forming a structure in which the sealing part 111 and the first snap-fit ​​part 113 are located on opposite sides of the case wall at the opening 121. At this time, at least part of the case wall at the opening 121 will be embedded in the snap-fit ​​groove 1131 formed by the first snap-fit ​​part 113 and the sealing part 111. In this way, the elastic sealing cover 11 will be fixed at the opening 121 and the opening 121 will be sealed.

[0064] It should be noted that, in Figure 7 In the structure shown, the opening 121 on the case 12 is approximately rectangular, and the sealing portion 111 of the matching elastic sealing cover 11 is also approximately rectangular. In other embodiments of this application, the shape of the opening 121 may also be circular or other irregular shapes, and correspondingly, the shape of the elastic sealing cover 11 will also change accordingly.

[0065] Figure 8 for Figure 6 Top view, Figure 9 for Figure 8 This is a cross-sectional view of AA. Figure 10 for Figure 9 A magnified view of a section at point C. For ease of description and understanding, it is represented by 7. Figure 9 and Figure 10 The current display orientation is Figure 7 and Figure 9 The shell wall at opening 121 shown in the diagram will be described. Figure 7 and Figure 9 In the structure shown, the opening 121 is approximately rectangular. The shell walls at the opening 121 include an upper shell wall 1211, a lower shell wall 1212, a left shell wall 1213, and a right shell wall 1214. Due to the structure of the watch case 12 itself, the upper shell wall 1211 at the opening 121 is connected to another shell plate 1215 of the watch case 12. Therefore, the only shell walls that can engage with the resilient sealing cover 11 are the lower shell wall 1212, the left shell wall 1213, and the right shell wall 1214. Please refer to... Figure 4 and Figure 7 ,based on Figure 7 In the structure shown, the first snap-fit ​​portion 113 of the elastic sealing cover 11 is provided only around the three sides of the connecting portion 112. In this way, the first snap-fit ​​portion 113 and the sealing portion 111 can form a snap-fit ​​groove 1131 that is adapted to the shell wall at the opening 121.

[0066] As can be seen from the above description, the structure of the elastic sealing cover 11 is adapted to the structure of the watch case 12 at the opening 121, and the structure at the opening 121 of the watch case 12 will affect the structure of the elastic sealing cover 11 itself. Figures 4 to 5The elastic sealing cap 11 shown is only one example of its application in sealing a specific opening 121 and is not intended to limit the application of the technical solution of this application. For example, in some other embodiments, there is an annular shell wall at the opening 121 that can engage with the snap-fit ​​groove 1131, and correspondingly, the first snap-fit ​​portion 113 of the elastic sealing cap 11 can also surround the entire circumference of the connecting portion 112.

[0067] It should also be noted that, Figures 6 to 9 The illustrated energy meter 1 is a three-phase energy meter 1. In some other embodiments of this application, the energy meter 1 may also be a single-phase energy meter 1.

[0068] In summary, this application provides an elastic sealing cover 11, which can be fixed at the opening 121 of the electricity meter 1 by compression deformation. In this way, the elastic sealing cover 11 can seal the opening 121, thereby preventing foreign objects from entering the electricity meter 1 through the opening 121, which helps to ensure the working stability of the electricity meter 1 and improve the performance of the electricity meter 1.

[0069] Please continue to refer to this. Figure 4 In one embodiment of this application, the elastic sealing cover 11 further includes a second snap-fit ​​portion 114, which is disposed on the side of the connecting portion 112 away from the sealing portion 111, and a snap-fit ​​interface 1141 is provided at the end of the second snap-fit ​​portion 114 away from the connecting portion 112.

[0070] Please combine Figure 4 and Figure 10 Based on the aforementioned elastic cover, in the structure of the electricity meter 1, the end of the electrical connection structure 13 facing the opening 121 is embedded in the card interface 1141, and the outer periphery of the electrical connection structure 13 is in contact with the inner wall of the card interface 1141.

[0071] Specifically, please refer to Figure 7 In some embodiments of this application, the area of ​​the opening 121 is relatively large. When the elastic sealing cover 11 is fixed at the opening 121 by compression, wrinkles may appear on the surface of the elastic sealing cover 11, which is not conducive to the stable setting of the elastic sealing cover 11.

[0072] Please combine Figure 4 , Figure 7 and Figure 10In some embodiments of this application, a second snap-fit ​​portion 114 is provided on the side of the connecting portion 112 away from the sealing portion 111, and a card interface 1141 is provided at the end of the second snap-fit ​​portion 114 away from the connecting portion 112. When the elastic sealing cover 11 is installed at the opening 121 of the energy meter 1, the end of the electrical connection structure 13 located inside the meter housing 12 facing the opening 121 can be embedded in the card interface 1141, and the outer periphery of the electrical connection structure 13 contacts the inner wall of the card interface 1141. In this way, the electrical connection structure 13 can support and flatten the elastic sealing cover 11, and the elastic sealing cover 11 can be more stably set at the opening 121, the sealing effect is more stable, and the appearance of the elastic sealing cover 11 is more aesthetically pleasing.

[0073] Please combine Figure 4 and Figure 10 It should be noted that, Figure 4 The card interface 1141 of the shown resilient sealing cover 11 has a shorter circumferential sidewall, which is designed to avoid obstructing the circuit board 14 in the electricity meter 1. In other embodiments of this application, the circumferential sidewalls of the card interface 1141 may be of equal length.

[0074] It should also be noted that the shape of the card interface 1141 is adapted to the shape of the electrical connection structure 13. Figure 7 In the structure shown, the portion of the electrical connection structure 13 that mates with the card interface 1141 is prism-shaped; therefore, the card interface 1141 is also prism-shaped. In other embodiments of this application, the portion of the electrical connection structure 13 that mates with the card interface 1141 may also be cylindrical; therefore, the shape of the card interface 1141 may also be a corresponding cylindrical shape. Besides these, the portion of the electrical connection structure 13 that mates with the card interface 1141 may have other shapes, which will not be elaborated here.

[0075] In addition, Figure 6 , Figure 7 and Figure 9 In the illustrated embodiment, the electrical connection structure 13 at the opening 121 is a socket B3. In other embodiments of this application, the electrical connection structure 13 may also take other forms, such as a pin B2, a USB interface, etc.

[0076] Please continue to refer to this. Figure 4 In some embodiments of this application, the end of the card interface 1141 is provided with a chamfer 11411 to facilitate the installation of the electrical connection structure 13.

[0077] Specifically, please combine Figure 4 and Figure 7As mentioned above, when the elastic sealing cover 11 is installed, the end of the electrical connection structure 13 facing the opening 121 will be embedded in the card interface 1141, and the outer periphery of the electrical connection structure 13 will contact the inner wall of the card interface 1141. A chamfer 11411 is provided at the end of the card interface 1141. In this way, the electrical connection structure 13 is easier to be inserted into the card interface 1141, and the installation of the elastic sealing cover 11 will be easier.

[0078] Please combine Figure 7 and Figure 10 In some embodiments of this application, the opening 121 includes a large end 121A and a small end 121B connected together, with the large end 121A being the portion of the opening 121 near the outside of the watch case 12. The sealing part 111 is embedded in the large end 121A, the connecting part 112 is embedded in the small end 121B, and the snap-fit ​​groove 1131 snaps into the case wall at the small end 121B. The surface of the sealing part 111 away from the connecting part 112 is flush with the outer surface of the case wall at the opening 121 of the watch case 12.

[0079] Please continue to refer to this. Figure 6 Based on the energy meter 1 provided by this embodiment, the surface of the sealing part 111 away from the connecting part 112 is flush with the outer surface of the shell wall at the opening 121 of the meter case 12. In this way, the elastic sealing cover 11 is not easy to fall off due to scratches, and the outer surface of the energy meter 1 will be smoother.

[0080] Please continue to refer to this. Figure 6 and Figure 7 In some embodiments of this application, the surface of the case 12 is further provided with a groove 122, which is connected to the large end 121A.

[0081] Specifically, when the energy meter 1 provided in this application is used as a slave unit B of a multi-user energy meter, it is sometimes necessary to remove the sealing cover on the energy meter 1 so that the energy meter 1 can be electrically connected to the next energy meter 1.

[0082] As described above, the sealing part 111 is embedded in the large end 121A, and the surface of the sealing part 111 away from the connecting part 112 is flush with the outer surface of the case wall where the opening 121 is provided on the case 12. Based on this, a groove 122 communicating with the large end 121A is provided on the surface of the case 12. The groove 122 provides operating space for removing the elastic sealing cover 11, so that the user can tear the elastic sealing cover 11 at the groove 122 to facilitate the removal of the sealing cover.

[0083] Figure 11 for Figure 4 The structural schematic diagram of the elastic sealing cap 11 shown from another perspective is provided below. Figure 11In one embodiment of this application, a component identifier 115 is provided on the side of the sealing portion 111 away from the connecting portion 112. The component identifier 115 helps the user identify the component at the resilient sealing cover 11.

[0084] Please combine Figure 6 , Figure 7 and Figure 10 In one embodiment of this application, component identifier 115 is an identifier for electrical connection structure 13.

[0085] Specifically, when the energy meter 1 provided in this application is used as a slave unit of a multi-user energy meter, multiple slave units need to be assembled. A component identification 115 of the electrical connection structure 13 is provided on the side of the sealing part 111 away from the connecting part 112. In this way, the user can quickly determine the location of the electrical connection structure 13, which helps to improve the assembly efficiency of the multi-user energy meter.

[0086] Please continue to refer to this. Figure 6 , Figure 7 and Figure 11 In one embodiment of this application, component identifier 115 is a pattern of a component covered by the elastic sealing cap 11. In other embodiments of this application, component identifier 115 may also be the name of a component or other code.

[0087] Please continue to refer to this. Figure 4 , Figure 5 , Figure 6 and Figure 11 In one embodiment of this application, the elastic sealing cover 11 is made of silicone rubber.

[0088] Specifically, silicone rubber is a high-performance elastic material with excellent deformation and sealing capabilities, as well as temperature resistance, weather resistance, and insulation. This application selects silicone rubber as the material for the elastic sealing cover 11, which meets all the usage requirements of the elastic sealing cover 11.

[0089] In addition, in some other embodiments of this application, the elastic sealing cover 11 may also be made of other materials that meet the requirements, such as nitrile rubber, and this application does not limit this.
