Description

Technical Field

[0001] This application relates to the field of electricity meter technology, and more particularly to 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 electricity meters typically consist of multiple electrically connected meters. In related technologies, when two adjacent meters are connected, the male connector of one meter is plugged into the female connector of the other meter. During the plugging process, the electrical connectors of the meters may become misaligned, affecting the electrical connection between the meters. Utility Model Content

[0004] This application provides an electricity meter that can avoid or reduce the misalignment of the electricity meter's electrical connector during the insertion process, thereby improving the reliability of the electricity meter's electrical connection.

[0005] The technical solution of this application is as follows:

[0006] In a first aspect, this application provides an electricity meter, including a meter housing, a circuit board, a first electrical connector, and a first protective member. The circuit board is located inside the meter housing. The first electrical connector includes a first connecting portion and a first plug-in portion. Along a first direction, the first electrical connector is electrically connected to one side of the circuit board via the first connecting portion. Along a second direction, the first plug-in portion is located on one side of the first connecting portion and extends along the second direction, and the meter housing has a notch exposing the first plug-in portion. Along the second direction, the first protective member contacts the first electrical connector to limit the displacement of the first electrical connector along the second direction.

[0007] The first protective component can apply a reverse force to the first electrical connector through the electricity meter provided in the first aspect, thereby offsetting or partially offsetting the insertion force applied to the first electrical connector by the external device. As a result, the resultant force on the first electrical connector in the second direction is reduced or eliminated, and the first electrical connector is less likely to be displaced in the second direction. In this way, the occurrence of the first electrical connector skew can be reduced, and the connection between the first electrical connector and the external device will be easier.

[0008] Furthermore, since the first electrical connector is less prone to displacement in the second direction, the first connection part is less likely to deform or break, and the connection between the first electrical connector and the circuit board is more stable.

[0009] In one possible design, the first electrical connector includes a first insulating housing for supporting and fixing the first connecting portion and the first plug portion.

[0010] The electricity meter also includes a second protective element that contacts the first insulating housing along the first direction, for limiting the displacement of the first electrical connector along the first direction.

[0011] In the energy meter provided by this embodiment, when the first electrical connector is connected to an external device through the first plug portion, in some cases, the force applied to the first electrical connector by the external device has a component force along the first direction. This application restricts the displacement of the first electrical connector in the first direction by using the second protective member, which can make the relative position of the first electrical connector in the first direction more stable. The first electrical connector is less likely to tilt during the plugging process. This helps to connect the first electrical connector to the external device and also helps to ensure the reliability of the connection between the first electrical connector and the circuit board.

[0012] In one possible design, along a first direction, a second protective member is disposed on one side of a first insulating shell, one side of the first insulating shell is in contact with the second protective member, and the other side of the first insulating shell is in contact with a circuit board.

[0013] The energy meter provided by this embodiment uses a circuit board to support the first electrical connector, and the cooperation between the circuit board and the second protective component improves the positional stability of the first electrical connector in the first direction, resulting in a compact and simple combined structure.

[0014] In one possible design, the electricity meter also includes a second electrical connector, with the first and second electrical connectors located on opposite sides of the meter housing.

[0015] One of the first electrical connectors and the second electrical connector is a male connector, and the other is a female connector.

[0016] The energy meter provided by this embodiment can be used as a slave unit in a multi-user energy meter. The multi-user energy meter includes multiple cascaded slave units. When multiple energy meters of this structure are assembled to form a multi-user energy meter, adjacent energy meters can be electrically connected through the plugging of male and female connectors. This improves the reliability of the connection between slave units in a multi-user energy meter and enhances data transmission quality.

[0017] In one possible design, the second electrical connector includes a second connecting portion and a second plug portion connected together. Along a first direction, the second electrical connector is electrically connected to one side of the circuit board via the second connecting portion. Along a second direction, the second plug portion is located on one side of the second connecting portion and extends along the second direction, serving as another external interface for the electricity meter.

[0018] The electricity meter also includes a third protective element along the second direction, which contacts the second electrical connector to limit the displacement of the second electrical connector along the second direction.

[0019] The third protective member of the energy meter provided by this embodiment has the same function as the first protective member for the first electrical connector. It is mainly used to limit the displacement of the second electrical connector in the second direction, prevent the second connecting part of the second connector from deforming or breaking during the insertion process, and facilitate the insertion and electrical connection between external devices and the second connecting part.

[0020] In one possible design, the second electrical connector includes a second insulating housing for supporting and securing the second connection portion and the second insertion portion.

[0021] The electricity meter also includes a fourth protective element, which contacts the second insulating housing along the first direction to limit the displacement of the second electrical connector along the first direction.

[0022] The fourth protective member of the electricity meter provided by this embodiment has the same function as the second protective member for the first electrical connector. It is mainly used to limit the displacement of the second electrical connector in the first direction and prevent the second electrical connector from tilting during the insertion process. This helps to connect the second electrical connector to external devices and also helps to ensure the reliability of the connection between the second electrical connector and the circuit board.

[0023] In one possible design, along the first direction, the fourth protective member is disposed on one side of the second insulating housing, one side of the second insulating housing is in contact with the fourth protective member, and the other side of the second insulating housing is in contact with the circuit board.

[0024] The energy meter provided by this embodiment uses a circuit board to support the second electrical connector, and the cooperation between the circuit board and the fourth protective component improves the positional stability of the second electrical connector in the first direction, resulting in a compact and simple combined structure.

[0025] In one possible design, at least one of the first protective member and the third protective member is in contact with the circuit board along the first direction to limit the displacement of the circuit board along the first direction.

[0026] The energy meter provided by this embodiment combines the protection of the first electrical connector and the second electrical connector with the fixing of the circuit board. This not only helps to simplify the installation structure of the circuit board, but also helps to improve the assembly efficiency of the energy meter.

[0027] In one possible design, the first protective member includes a first limiting rib and a first supporting rib. The first limiting rib is in contact with the first electrical connector, and the first supporting rib is located on the side of the first limiting rib away from the first electrical connector. The first supporting rib and the first limiting rib form a triangular support structure.

[0028] And / or, the third protective component includes a second limiting rib and a second supporting rib, the second limiting rib being in contact with the second electrical connector, the second supporting rib being disposed on the side of the second limiting rib away from the second electrical connector, and the second supporting rib and the second limiting rib forming a triangular support structure.

[0029] The electricity meter provided by this embodiment includes a first protective member comprising a first limiting rib and a first supporting rib, wherein the first supporting rib and the first limiting rib form a triangular support structure. This helps to improve the strength of the first protective member, thereby helping to limit the displacement of the first electrical connector along the second direction. Similarly, the third protective member includes a second limiting rib and a second supporting rib, wherein the second supporting rib and the second limiting rib form a triangular support structure. Its beneficial effects are similar to those of the first protective member, and will not be elaborated here.

[0030] In one possible design, along the second direction, the first electrical connector is recessed relative to the case, and the second electrical connector is protruding relative to the case.

[0031] The watch case also includes a protective section located on the outer periphery of the portion of the second electrical connector that protrudes from the watch case. This reduces the risk of damage to the second electrical connector. Attached Figure Description

[0057] The present application will be described in detail below with reference to the accompanying drawings.

[0058] Figure 1 The figure shown is a three-dimensional structural diagram of an electricity meter provided in an embodiment of this application. Figure 2 for Figure 1 Top view, Figure 3 for Figure 2 AA cross-section view. Figure 4 for Figure 3 The diagram shows the outline of the first electrical connector. Figure 5 for Figure 3 The diagram shown is a structural representation of the first electrical connector from another perspective. Figure 6 for Figure 3 A partial cross-sectional view of the first electrical connector shown from another perspective.

[0059] Please refer to Figures 1 to 6 The electricity meter provided in this application includes a meter housing 1, a circuit board 2, a first electrical connector 3, and a first protective member 4. The circuit board 2 is located inside the meter housing 1. The first electrical connector 3 includes a first connecting portion 31 and a first plug-in portion 32 connected together. Along a first direction D1, the first electrical connector 3 is electrically connected to one side of the circuit board 2 via the first connecting portion 31. Along a second direction D2, the first plug-in portion 32 is located on one side of the first connecting portion 31, and extends along the second direction D2. The meter housing 1 has a notch 1A exposing the first plug-in portion 32. Along the second direction D2, the first protective member 4 contacts the first electrical connector 3 to limit the displacement of the first electrical connector 3 along the second direction D2.

[0060] Specifically, please refer to Figures 4 to 6 The first electrical connector 3 is a component used to connect circuits. Its main function is to transmit current or signals to ensure the normal operation of electrical equipment. The electrical connector includes a first insertion portion 32 and a first connecting portion 31, where the first insertion portion 32 and the first connecting portion 31 are different conductive parts of the first electrical connector 3. The function of the first connecting portion 31 is to connect the first electrical connector 3 to the internal circuit of the device, and the function of the first insertion portion 32 is to connect the first electrical connector 3 to the external circuit of the device.

[0061] Please combine Figure 1 and Figure 3 ,exist Figure 1 and Figure 3 In the structure shown, the electricity meter is equipped with a first electrical connector 3. A notch 1A is provided on the meter housing 1 at the location opposite to the first insertion portion 32 of the first electrical connector 3, providing a connection channel between the electricity meter and an external device. When this electricity meter is used for multi-household electricity meters, it can be connected to other electricity meters through the first electrical connector 3.

[0062] Please combine Figure 3 and Figure 6In this application, the first electrical connector 3 is electrically connected to one side of the circuit board 2 via the first connecting portion 31, and the first plug-in portion 32 extends along the second direction D2. When the energy meter is connected to an external device via the first electrical connector 3, the electrical connector of the external device will plug into the first plug-in portion 32 along the second direction D2, and the first electrical connector 3 will be subjected to a plugging force along the second direction D2. Since the first protective member 4 is in contact with the first electrical connector 3 along the second direction D2, the first protective member 4 can apply a reverse force to the first electrical connector 3, offsetting or partially offsetting the plugging force applied to the first electrical connector 3 by the external device. Consequently, the resultant force on the first electrical connector 3 in the second direction D2 is reduced or eliminated, and the first electrical connector 3 is less likely to shift in the second direction D2, which can reduce the occurrence of the first electrical connector 3 skewness. The connection between the first electrical connector 3 and the external device will be more reliable and easier.

[0063] Furthermore, since the first electrical connector 3 is less prone to displacement in the second direction D2, the first connection part 31 is less likely to deform or break, and the connection between the first electrical connector 3 and the circuit board 2 is more stable.

[0064] It should be noted that, in Figure 3 In the structure shown, in the second direction D2, the first protective member 4 is fixed to the end of the first electrical connector 3 away from the first insertion portion 32. In other embodiments of this application, the first protective member 4 may also be provided in other locations, as long as it satisfies the requirement that the first protective member 4 blocks the displacement of the first electrical connector 3 in the second direction D2. Further details will not be elaborated upon in this application.

[0065] Please continue to refer to this. Figure 3 In some embodiments of this application, the first electrical connector 3 includes a first insulating shell 33, which is used to support and fix the first connecting part 31 and the first plug-in part 32.

[0066] The electricity meter also includes a second protective element 5, which is in contact with the first insulating shell 33 along the first direction D1, and is used to limit the displacement of the first electrical connector 3 along the first direction D1.

[0067] Specifically, please combine Figure 1 , Figure 3 and Figure 6When the first electrical connector 3 is connected to an external device through the first insertion part 32, in some cases, the force applied to the first electrical connector 3 by the external device has a component force along the first direction D1. This application restricts the displacement of the first electrical connector 3 in the first direction D1 by the second protective member 5, which can make the relative position of the first electrical connector 3 in the first direction D1 more stable. The first electrical connector 3 is less likely to tilt during the insertion process. This helps the connection between the first electrical connector 3 and the external device, and also helps to ensure the reliability of the connection between the first electrical connector 3 and the circuit board 2.

[0068] It should be noted that, Figure 3 In the structure shown, the first insulating shell 33 is approximately rectangular, and the second protective member 5 is a straight plate along the first direction D1. In other embodiments of this application, the first insulating shell 33 may also be cylindrical or other irregular shapes. In that case, the mating structure between the second protective member 5 and the first electrical connector 3 will also change. This application does not impose any restrictions on this.

[0069] Please continue to refer to this. Figure 3 In some embodiments of this application, along the first direction D1, one side of the first insulating shell 33 is in contact with the second protective member 5, and the other side of the first insulating shell 33 is in contact with the circuit board 2.

[0070] Specifically, in this embodiment, the first insulating shell 33 is sandwiched between the second protective member 5 and the circuit board 2. In this way, the circuit board 2 can better support the first electrical connector 3. At the same time, the circuit board 2 and the second protective member 5 can cooperate well, improving the positional stability of the first electrical connector 3 in the first direction D1.

[0071] The energy meter provided by this embodiment supports the first electrical connector 3 by means of the circuit board 2, and improves the positional stability of the first electrical connector 3 in the first direction D1 by means of the cooperation between the circuit board 2 and the second protective member 5. It has the characteristics of compact and simple combined structure.

[0072] Please combine Figure 2 and Figure 3 In other embodiments of this application, the electricity meter further includes a second electrical connector 6, with the first electrical connector 3 and the second electrical connector 6 located on opposite sides of the meter housing 1. One of the first electrical connector 3 and the second electrical connector 6 is a male connector, and the other is a female connector.

[0073] The energy meter provided in this embodiment can be used as a slave unit in a multi-user energy meter. The multi-user energy meter includes multiple cascaded slave units. When multiple energy meters of this structure are assembled to form a multi-user energy meter, adjacent energy meters can be electrically connected through the plugging of male and female connectors. This improves the reliability of the connection between slave units in a multi-user energy meter and enhances data transmission quality.

[0074] It should be noted that, in Figure 3 In the structure shown, the first electrical connector 3 is a female connector and the second electrical connector 6 is a male connector. In some other embodiments of this application, the first electrical connector 3 may also be a male connector and the second electrical connector 6 may also be a female connector.

[0075] Please continue to refer to this. Figure 3 In some embodiments of this application, the second electrical connector 6 includes a second connecting portion 61 and a second plug-in portion 62 connected together. Along the first direction D1, the second electrical connector 6 is electrically connected to one side of the circuit board 2 via the second connecting portion 61. Along the second direction D2, the second plug-in portion 62 is located on one side of the second connecting portion 61, and extends along the second direction D2, serving as another external interface of the energy meter.

[0076] The electricity meter also includes a third protective element 7 along the second direction D2. The third protective element 7 is in contact with the second electrical connector 6 and is used to limit the displacement of the second electrical connector 6 along the second direction D2.

[0077] In this embodiment, the function of the third protective member 7 on the second electrical connector 6 is the same as that of the first protective member 4 on the first electrical connector 3. It is mainly used to limit the displacement of the second electrical connector 6 in the second direction D2, prevent the second connecting part 61 of the second electrical connector 6 from deforming or breaking during the insertion process, and facilitate the insertion and electrical connection between external devices and the second plug-in part 62.

[0078] It should be noted that, in Figure 3 In the structure shown, the third protective member 7 is fixed to the end of the second electrical connector 6 away from the second insertion portion 62 in the second direction D2. In other embodiments of this application, the third protective member 7 may also be provided in other locations, as long as the second protective member 5 can block the displacement of the second electrical connector 6 in the second direction D2. This will not be elaborated further in this application.

[0079] Please continue to refer to this. Figure 3 In some embodiments of this application, the second electrical connector 6 includes a second insulating housing 63, which is used to support and fix the second connecting portion 61 and the second plug-in portion 62.

[0080] The electricity meter also includes a fourth protective element 8, which is in contact with the second insulating housing 63 along the first direction D1, and is used to limit the displacement of the second electrical connector 6 along the first direction D1.

[0081] In this embodiment, the function of the fourth protective member 8 on the second electrical connector 6 is the same as that of the second protective member 5 on the first electrical connector 3. It is mainly used to limit the displacement of the second electrical connector 6 in the first direction D1 and prevent the second electrical connector 6 from tilting during the insertion process. This helps the second electrical connector 6 to connect with external devices and also helps to ensure the reliability of the connection between the second electrical connector 6 and the circuit board 2.

[0082] Please continue to refer to this. Figure 3 In some embodiments of this application, along the first direction D1, one side of the second insulating shell 63 is in contact with the fourth protective member 8, and the other side of the second insulating shell 63 is in contact with the circuit board 2.

[0083] The energy meter provided by this embodiment supports the second electrical connector 6 by means of the circuit board 2, and improves the positional stability of the second electrical connector 6 in the first direction D1 by means of the cooperation between the circuit board 2 and the fourth protective member 8. It has the characteristics of compact and simple combined structure.

[0084] Please continue to refer to this. Figure 3 In some embodiments of this application, at least one of the first protective member 4 and the third protective member 7 is in contact with the circuit board 2 along the first direction D1 to limit the displacement of the circuit board 2 along the first direction D1.

[0085] Specifically, please combine Figure 3 and Figure 7 In some embodiments of this application, the watch case 1 includes a cover 11 and a bottom case 12 that can be interlocked. The bottom case 12 has positioning structures, such as positioning posts 121, which support the circuit board 2. However, the connection between the circuit board 2 and the positioning posts 121 is not fixed. A first electrical connector 3 and a second electrical connector 6 are provided on the side of the circuit board 2 away from the bottom case 12. The cover 11 has corresponding first protective members 4 and second protective members 5. Thus, when the cover 11 and the watch case 1 are interlocked, along the second direction D2, the first protective member 4 contacts the first electrical connector 3, and the second protective member 5 contacts the second electrical connector 6. Therefore, the first protective member 4 can restrict the displacement of the first electrical connector 3 along the second direction D2, and the second protective member 5 can restrict the displacement of the second electrical connector 6 along the second direction D2.

[0086] Based on this, at least one of the first protective member 4 and the third protective member 7 comes into contact with the circuit board 2, thus determining the position of the circuit board 2 in the first direction D1.

[0087] As can be seen from the above, the electricity meter provided by this embodiment combines the protection of the first electrical connector 3 and the second electrical connector 6 with the fixing of the circuit board 2. This not only helps to simplify the installation structure of the circuit board 2, but also helps to improve the assembly efficiency of the electricity meter.

[0088] It should be noted that, Figure 3 , Figure 7 The illustrated electricity meter structure is only one embodiment of the technical solution of this application. Based on the core idea of ​​this application, the electricity meter can also have other structural forms. For example, the support structure of the circuit board 2 can be set on the meter cover 11 instead of the bottom shell 12. The first protective component 4 and the second protective component 5 can be set on the bottom shell 12, etc.

[0089] Figure 8 This is a schematic diagram of the structure of the meter cover provided in the embodiments of this application. Please refer to it. Figure 3 and Figure 8 In some embodiments of this application, the first protective member 4 includes a first limiting rib 41 and a first supporting rib 42. The first limiting rib 41 is in contact with the first electrical connector 3, and the first supporting rib 42 is disposed on the side of the first limiting rib 41 away from the first electrical connector 3, and the first supporting rib 42 and the first limiting rib 41 form a triangular support structure.

[0090] The third protective component 7 includes a second limiting rib 71 and a second supporting rib 72. The second limiting rib 71 is in contact with the second electrical connector 6, and the second supporting rib 72 is located on the side of the second limiting rib 71 away from the second electrical connector 6. The second supporting rib 72 and the second limiting rib 71 form a triangular support structure.

[0091] Please continue to refer to this. Figure 3 and Figure 8 When the electricity meter is connected to an external device through the first electrical connector 3, the first electrical connector 3 and the first protective member 4 are subjected to a plugging force along the second direction D2. The first protective member 4 can also apply a reverse force to the first electrical connector 3, offsetting or partially offsetting the plugging force applied externally to the first electrical connector 3. The first protective member 4 includes a first limiting rib 41 and a first supporting rib 42, and the first supporting rib 42 and the first limiting rib 41 form a triangular support structure. This helps to increase the strength of the first protective member 4, thereby helping to limit the displacement of the first electrical connector 3 along the second direction D2.

[0092] Similarly, the third protective component 7 includes a second limiting rib 71 and a second supporting rib 72. The second supporting rib 72 and the second limiting rib 71 form a triangular support structure, and its beneficial effects are similar to those of the first protective component 4, which will not be elaborated here.

[0093] Please continue to refer to this. Figure 3In some embodiments of this application, along the second direction D2, the first electrical connector 3 is recessed relative to the watch case 1, and the second electrical connector 6 protrudes relative to the watch case 1. The watch case 1 also includes a protective portion 9, which is disposed on the outer periphery of the portion of the second electrical connector 6 that protrudes relative to the watch case 1.

[0094] Specifically, electricity meters undergo production, transportation, and assembly processes, during which bumps and pressures are sometimes unavoidable. When bumps and pressures occur, the parts protruding from the meter casing 1 are usually the most severely damaged areas. Therefore, this application provides a protective part 9 around the outer periphery of the second electrical connector 6, which protrudes from the meter casing 1, thereby reducing damage to the second electrical connector 6.

[0095] Please continue to refer to this. Figure 3 and Figure 8 In some embodiments of this application, the first protective member 4, the second protective member 5, the third protective member 7, the fourth protective member 8, and the protective part 9 are all integrally formed with the meter housing 1, which facilitates the assembly of the electricity meter. In other embodiments of this application, the first protective member 4, the second protective member 5, the third protective member 7, the fourth protective member 8, and the protective part 9 may also have other configurations.

For example, in the claims, any of the claimed embodiments can be used in any combination.
