Utility Model Content

[0003] This application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, the present application proposes an electric energy meter.

[0005] In view of this, the present application provides an electric energy meter, including: a meter body, a main control board is provided in the meter body, the main control board has a first connector, and a positioning groove is provided on the meter body; a protective cover, the protective cover is detachably connected to the meter body, the meter body and the protective cover enclose an installation cavity, and the positioning groove is located in the installation cavity; a circuit board group, located in the installation cavity, the circuit board group includes a circuit board and a handle, the handle is provided on the circuit board, the circuit board is detachably connected to the positioning groove, the circuit board has a second connector, the first connector and the second connector are electrically connected, and the circuit board is used for the main control board to transmit data.

[0006] The present application provides an electric energy meter comprising a meter body, a protective cover and a circuit board assembly. The circuit board assembly comprises a circuit board and a handle.

[0007] The protective cover and the meter body are detachably connected. When the protective cover and the meter body are assembled, the meter body and the protective cover enclose an installation cavity.

[0008] A positioning groove is provided on the meter body, and the positioning groove is located in the installation cavity. The installation cavity is used to accommodate the circuit board group. The positioning groove is used to install and fix the circuit board group to effectively limit the circuit board group.

[0009] The process of assembling the circuit board assembly is as follows: holding the handle of the circuit board assembly, inserting the circuit board into the positioning slot, plugging and mating the first connector and the second connector to secure the circuit board assembly to the watch body, and then installing the protective cover on the watch body. The watch body and protective cover cooperate to enclose a mounting cavity for accommodating the circuit board assembly, blocking moisture, dirt, and other environmental contaminants from entering the circuit board assembly, providing structural support for the effective operation of the circuit board and ensuring the service life of the circuit board.

[0010] The process of disassembling the circuit board assembly is as follows: remove the protective cover from the watch body to expose the circuit board assembly outside the watch body, and then hold the handle to pull the circuit board out of the positioning slot.

[0011] In other words, the present application rationally utilizes the structure of the electric energy meter, using the positioning groove and the first connector to mount and secure the circuit board assembly, and the meter body and protective cover to protect the circuit board assembly. The process of assembling and disassembling the circuit board assembly is simple and easy to operate, and the efficiency of disassembling and assembling the electric energy meter is high. At the same time, the present application eliminates the installation box used to install the circuit board in the related art, and rationally utilizes the structure of the meter body and protective cover. While ensuring the effectiveness and feasibility of mounting the circuit board assembly, it can also effectively block water vapor, dirt, etc. in the environment, and has the advantage of low production cost.

[0012] Furthermore, the circuit board assembly includes a circuit board and a handle. The handle is provided on the circuit board, and the circuit board can be indirectly grasped through the handle, allowing the circuit board and the positioning slot to be effectively removed and assembled. Directly grasping the circuit board to remove and assemble it can easily stain and damage the circuit board. Therefore, the rational design of the circuit board assembly structure ensures convenient assembly and removal of the circuit board while also extending the service life of the circuit board.

[0013] It is understood that the protective cover and the watch body are detachably connected, and can be separated from the watch body or assembled together according to actual use needs. This arrangement simplifies the assembly structure of the protective cover and the watch body, simplifies the disassembly process, reduces the difficulty of disassembly of the protective cover and the watch body, and facilitates cleaning of the protective cover and the watch body and subsequent repair and maintenance.

[0014] It is understood that the circuit board and the positioning slot are detachably connected, and the circuit board and the positioning slot can be separated or assembled together according to actual use needs. This arrangement simplifies the assembly structure of the circuit board assembly and the watch body, simplifies the assembly and disassembly process, reduces the difficulty of assembly and disassembly of the circuit board assembly and the watch body, and facilitates cleaning of the circuit board assembly and the watch body and subsequent repair and maintenance.

[0015] It is understood that the main control board has a first connector and the circuit board has a second connector. After the circuit board is assembled to the meter body, the first connector and the second connector are plugged into each other to achieve an electrical connection between the main control board and the circuit board. The circuit board is used to transmit data from the main control board to other devices.

[0016] The electric energy meter described above in this application may also have the following additional technical features:

[0017] In some embodiments, optionally, the watch body includes: a bottom shell, the bottom shell includes a bottom plate and a vertical plate connected to each other, the bottom plate is provided with a positioning groove, and the vertical plate is located between the positioning groove and the main control board.

[0018] In this embodiment, the structure of the watch body is further defined.

[0019] The watch body comprises a bottom shell, the bottom shell comprises a bottom plate and a vertical plate, the vertical plate is connected to the bottom plate, and the bottom plate is provided with a positioning groove.

[0020] The vertical plate is located between the positioning slot and the main control board. That is, the vertical plate is located between the circuit board and the main control board. The vertical plate has the function of separating the circuit board and the main control board. While meeting the use requirements of the circuit board and the main control board for electrical connection, it can also ensure the safety requirements of the main control board and the circuit board.

[0021] In some embodiments, optionally, the table body further includes: an upper cover, the upper cover is connected to the vertical plate, and the upper cover, the bottom shell and the protective cover enclose an installation cavity; the upper cover is provided with a first extension plate, the first extension plate is located on the side of the vertical plate away from the main control board, the first extension plate is provided with a guide groove, the guide groove is spaced apart from the bottom plate, the guide groove extends from the vertical plate to the bottom plate, and the circuit board is plugged into the guide groove.

[0022] In this embodiment, the structure of the watch body is further defined.

[0023] The meter body also includes an upper cover connected to the vertical plate. The upper cover, the bottom shell and the protective cover enclose an installation cavity for accommodating the circuit board assembly.

[0024] Furthermore, the upper cover is provided with a first extension plate, which is located on the side of the vertical plate away from the main control plate. The first extension plate is provided with a guide groove, which is spaced apart from the bottom plate and extends from the vertical plate to the bottom plate.

[0025] The guide groove has the function of guiding the circuit board, which can ensure the matching size of the circuit board and the positioning groove, so that the circuit board can be smoothly inserted into the positioning groove.

[0026] Specifically, when assembling the circuit board assembly, the circuit board is first plugged into the guide groove, and then the circuit board slides along the guide groove toward the bottom plate of the bottom shell and is correspondingly inserted into the positioning groove of the top plate.

[0027] It can be understood that the extension direction of the guide groove is different from the extension direction of the positioning groove. The guide groove, the positioning groove, the first joint and the second joint cooperate to achieve the common limitation of the circuit board in multiple dimensions, which can jointly limit the movement trajectory of the circuit board from multiple directions and enhance the stability and reliability of the assembled circuit board.

[0028] The guide groove is spaced apart from the bottom plate. This arrangement reduces the material input for the guide groove while ensuring the guiding function of the guide groove, which is beneficial to reducing the production cost of the product.

[0029] In some embodiments, optionally, the upper cover also includes a second extension plate; the watch body also includes a support plate, the support plate and the second extension plate are both located on the side of the vertical plate away from the positioning groove, and the main control plate is abutted between the second extension plate and the support plate.

[0030] In this embodiment, the structure of the watch body is further defined.

[0031] The upper cover further includes a second extension plate, and the watch body further includes a support plate that cooperates with the second extension plate.

[0032] Specifically, the support plate and the second extension plate are both located on the side of the vertical plate facing away from the positioning slots. Specifically, the support plate is located on the side of the vertical plate facing away from the positioning slots, and the second extension plate is also located on the side of the vertical plate facing away from the positioning slots. The support plate and the second extension plate are spaced apart, and the main control board is inserted into the gap between the main control board and the second extension plate. The support plate supports the main control board, while the second extension plate holds the main control board in place, ensuring that it is securely mounted between the support plate and the upper cover.

[0033] In other words, the upper cover not only has the function of guiding the circuit board, but also has the function of fixing the main control board, which enriches the function of the upper cover, can ensure the matching size of the main control board and the circuit board, and provides reliable structural support for the effective assembly of the first connector of the main control board and the second connector of the circuit board.

[0034] In some embodiments, optionally, the upper cover is provided with an escape opening, the escape opening is located between the first extension plate and the second extension plate, and the first joint is located at the escape opening.

[0035] The upper cover is provided with a clearance opening, where the first connector is located. The clearance opening is used to clear the first connector. The clearance opening is located between the first and second extension plates. The first extension plate has a guide groove that guides the circuit board and plugs into it. The clearance opening is located on one side of the first extension plate. This effectively defines the mating dimensions between the circuit board and the first connector, and thus the mating dimensions between the second connector and the first connector, providing structural support for the effective electrical connection between the first and second connectors.

[0036] It is understood that the relief also serves to provide clearance for the second connector on the circuit board, allowing at least a portion of the second connector to be located within the relief and effectively electrically connected to the first connector. This arrangement effectively utilizes the space in the upper cover, helping to reduce the overall fit between the circuit board assembly and the upper cover from the vertical plate to the base plate, and also helps to reduce the overall fit between the watch body and the protective cover from the vertical plate to the base plate.

[0037] In some embodiments, optionally, there are multiple positioning grooves, and the multiple positioning grooves are arranged at intervals.

[0038] In this embodiment, the number and arrangement positions of the positioning grooves are further defined.

[0039] Specifically, there are multiple positioning grooves.

[0040] A plurality of positioning grooves are arranged at intervals.

[0041] This arrangement increases the mating area and mating angle between the meter body and the circuit board, and can ensure the effectiveness and feasibility of assembling the circuit board group.

[0042] In some embodiments, optionally, the handle is provided with a slot, and the circuit board is detachably plugged into the slot.

[0043] In this embodiment, the matching structure of the handle and the circuit board is further defined.

[0044] The handle and circuit board are detachably connected. They can be separated or assembled together depending on actual use. This configuration simplifies the assembly of the handle and circuit board, simplifies the assembly and disassembly process, and reduces the difficulty of assembly and disassembly. It also facilitates cleaning of the handle and circuit board, as well as subsequent repair and maintenance.

[0045] Specifically, the handle is provided with a slot, and the circuit board is detachably plugged into the slot. This arrangement can increase the contact area between the handle and the circuit board, which is conducive to enhancing the stability and reliability of the assembly of the handle and the circuit board.

[0046] In some embodiments, optionally, the handle is provided with a mounting groove, the groove opening of the mounting groove faces the positioning groove, and at least a portion of the second connector is located in the mounting groove.

[0047] In this embodiment, the structure of the handle is further defined.

[0048] Specifically, the handle is provided with a mounting groove, the notch of the mounting groove faces the positioning groove, and the mounting groove has the function of accommodating the second joint, so that at least a part of the second joint is located in the mounting groove.

[0049] After the circuit board and the handle are assembled, at least a portion of the second connector of the circuit board will extend into the mounting groove. This can reduce the overall dimensions of the circuit board and the handle, which is beneficial for reducing the space occupied in the mounting cavity and the overall dimensions of the electric energy meter.

[0050] It can be understood that at least a portion of the second connector is located in the installation groove, which has the function of protecting the second connector, reducing the external force directly acting on the second connector, and can reduce the probability of damage to the second connector, which is beneficial to extending the service life of the circuit board.

[0051] In some embodiments, optionally, a first recess and a second recess are provided on the outer surface of the handle, and the first recess and the second recess are arranged opposite to each other along a direction from the main control board to the installation cavity.

[0052] In this embodiment, the structure of the handle is further defined.

[0053] The outer surface of the handle is provided with a first recess and a second recess. Along the direction from the main control board to the installation cavity, the first recess and the second recess are arranged opposite to each other.

[0054] The first recess and the second recess can be used as hand buckles of the handle, and the handle can be clamped by the first recess and the second recess to facilitate the removal and placement of the circuit board, and facilitate the assembly and disassembly of the circuit board and the positioning groove.

[0055] The structural arrangement of the first recess and the second recess can increase the contact area and contact angle between the hand and the handle, and can ensure comfort in gripping the handle.

[0056] In some embodiments, optionally, a third recess and a fourth recess are provided on the outer surface of the handle, and the third recess and the fourth recess are arranged opposite to each other along a direction perpendicular to the main control board and the installation cavity.

[0060] The structural arrangement of the third recess and the fourth recess can increase the contact area and contact angle between the hand and the handle, and can ensure comfort in clamping the handle.

[0061] In some embodiments, the outer surface of the handle optionally includes a first recess and a second recess, the first recess and the second recess being disposed opposite each other along a direction from the main control board to the mounting cavity. The outer surface of the handle further includes a third recess and a fourth recess, the third recess and the fourth recess being disposed opposite each other along a direction perpendicular to the direction from the main control board to the mounting cavity.

[0131] The watch body 100 further includes an upper cover 150 connected to the vertical plate 144. The upper cover 150, the bottom shell 140 and the protective cover 200 enclose a mounting cavity 300 for accommodating the circuit board assembly 400.

[0132] Furthermore, the upper cover 150 is provided with a first extension plate 152, which is located on the side of the vertical plate 144 facing away from the main control board 110. The first extension plate 152 is provided with a guide groove 154, which is spaced apart from the bottom plate 142 and extends from the vertical plate 144 to the bottom plate 142.

[0133] The guide groove 154 has the function of guiding the circuit board 410 , and can ensure the matching dimensions of the circuit board 410 and the positioning groove 130 , so that the circuit board 410 can be smoothly inserted into the positioning groove 130 .

[0134] Specifically, when assembling the circuit board assembly 400 , the circuit board 410 is first plugged into the guide slot 154 , and then slides along the guide slot 154 toward the bottom plate 142 of the bottom shell 140 and is correspondingly inserted into the positioning slot 130 of the top plate.

[0135] It can be understood that the extension direction of the guide groove 154 is different from the extension direction of the positioning groove 130. The guide groove 154, the positioning groove 130, the first joint 120 and the second joint 412 cooperate to achieve the common limitation of the circuit board 410 in multiple dimensions, and can jointly limit the movement trajectory of the circuit board 410 from multiple directions, and can enhance the stability and reliability of the assembled circuit board 410.

[0136] The guide groove 154 is spaced apart from the bottom plate 142 . This arrangement reduces the material input for the guide groove 154 while ensuring the guiding function of the guide groove 154 , thereby reducing the production cost of the product.

[0137] In some embodiments, optionally, as Figure 2 and Figure 3 As shown, the upper cover 150 further includes a second extension plate 156 .

[0138] The watch body 100 further includes a support plate 160 .

[0139] The support plate 160 and the second extension plate 156 are both located on a side of the vertical plate 144 away from the positioning groove 130 .

[0140] The main control board 110 is abutted between the second extension board 156 and the support board 160 .

[0141] In this embodiment, the structure of the watch body 100 is further defined.

[0142] The upper cover 150 further includes a second extension plate 156 , and the watch body 100 further includes a support plate 160 . The support plate 160 cooperates with the second extension plate 156 .

[0143] Specifically, the support plate 160 and the second extension plate 156 are both located on the side of the vertical plate 144 facing away from the positioning slot 130. That is, the support plate 160 is located on the side of the vertical plate 144 facing away from the positioning slot 130, and the second extension plate 156 is also located on the side of the vertical plate 144 facing away from the positioning slot 130. The support plate 160 and the second extension plate 156 are spaced apart, and the main control board 110 is inserted into the gap between the main control board 110 and the second extension plate 156. The support plate 160 supports the main control board 110, while the second extension plate 156 holds the main control board 110 in place, ensuring that the main control board 110 is securely mounted between the support plate 160 and the upper cover 150.

[0144] That is to say, the upper cover 150 not only has the function of guiding the circuit board 410, but also has the function of fixing the main control board 110, which enriches the function of the upper cover 150, can ensure the matching dimensions of the main control board 110 and the circuit board 410, and provides reliable structural support for the effective assembly of the first connector 120 of the main control board 110 and the second connector 412 of the circuit board 410.

[0145] In some embodiments, optionally, as Figure 3 As shown, the upper cover 150 is provided with an escape opening 158 .

[0146] The escape opening 158 is located between the first extension plate 152 and the second extension plate 156 .

[0147] The first joint 120 is located at the avoidance opening 158 .

[0148] In this embodiment, the structure of the upper cover 150 is further defined.

[0149] The upper cover 150 is provided with a clearance opening 158, where the first connector 120 is located. The clearance opening 158 is designed to clear the first connector 120. The clearance opening 158 is located between the first extension plate 152 and the second extension plate 156. The first extension plate 152 has a guide slot 154 that guides the circuit board 410 and engages with it. The clearance opening 158 is located on one side of the first extension plate 152. This defines the mating dimensions between the circuit board 410 and the first connector 120, and thus the mating dimensions between the second connector 412 of the circuit board 410 and the first connector 120, providing structural support for the effective electrical connection between the first connector 120 and the second connector 412.

[0150] It will be appreciated that the clearance opening 158 also serves to provide clearance for the second connector 412 of the circuit board 410, allowing at least a portion of the second connector 412 to be located within the clearance opening 158 and effectively electrically connected to the first connector 120. This arrangement rationally utilizes the space within the upper cover 150, facilitating a reduction in the overall fit between the circuit board assembly 400 and the upper cover 150 in the direction from the vertical plate 144 to the bottom plate 142, and also facilitating a reduction in the overall fit between the watch body 100 and the protective cover 200 in this direction.

[0151] In some embodiments, optionally, as Figure 3 As shown, there are multiple positioning grooves 130, and the multiple positioning grooves 130 are arranged at intervals.

[0152] In this embodiment, the number and arrangement positions of the positioning grooves 130 are further defined.

[0153] Specifically, there are multiple positioning grooves 130 .

[0154] The plurality of positioning grooves 130 are arranged at intervals.

[0155] This arrangement increases the mating area and mating angle between the watch body 100 and the circuit board 410 , and can ensure the effectiveness and feasibility of assembling the circuit board group 400 .

[0156] In some embodiments, optionally, as Figure 2 and Figure 6 As shown, the handle 420 is provided with a slot 422 , and the circuit board 410 is detachably plugged into the slot 422 .

[0157] In this embodiment, the matching structure between the handle 420 and the circuit board 410 is further defined.

[0158] The handle 420 is detachably connected to the circuit board 410. The handle 420 can be separated from the circuit board 410 or assembled together, depending on actual use. This arrangement simplifies the assembly structure of the handle 420 and the circuit board 410, simplifies the assembly and disassembly process, reduces the difficulty of assembly and disassembly, and facilitates cleaning, subsequent repair, and maintenance of the handle 420 and the circuit board 410.

[0159] Specifically, the handle 420 is provided with a slot 422, and the circuit board 410 is detachably plugged into the slot 422. This arrangement can increase the contact area between the handle 420 and the circuit board 410, which is conducive to enhancing the stability and reliability of the assembly of the handle 420 and the circuit board 410.

[0160] In some embodiments, optionally, as Figure 5 As shown, the handle 420 is provided with a mounting slot 424 .

[0161] The notch 4242 of the mounting slot faces the positioning slot 130 .

[0162] At least a portion of the second connector 412 is located in the mounting groove 424 .

[0163] In this embodiment, the structure of the handle 420 is further defined.

[0164] Specifically, the handle 420 is provided with a mounting groove 424 , the groove opening 4242 of which faces the positioning groove 130 . The mounting groove 424 has the function of accommodating the second connector 412 , so that at least a portion of the second connector 412 is located in the mounting groove 424 .

[0165] After the circuit board 410 and the handle 420 are assembled, at least a portion of the second connector 412 of the circuit board 410 extends into the mounting groove 424. This reduces the overall dimensions of the circuit board 410 and the handle 420, thereby reducing the space occupied by the mounting cavity 300 and the overall dimensions of the electric energy meter 10.

[0166] It can be understood that at least a portion of the second connector 412 is located in the installation groove 424. The installation groove 424 has the function of protecting the second connector 412, reducing the external force directly acting on the second connector 412, and reducing the probability of damage to the second connector 412, which is beneficial to extending the service life of the circuit board 410.

[0167] In some embodiments, optionally, as Figure 6 As shown, the outer surface of the handle 420 is provided with a first recess 425 and a second recess 426 .

[0172] The structural arrangement of the first recess 425 and the second recess 426 can increase the contact area and contact angle between the hand and the handle 420 , thereby ensuring comfort in gripping the handle 420 .

[0173] In some embodiments, optionally, as Figure 5 and Figure 6 As shown, the outer surface of the handle 420 is provided with a third recess 427 and a fourth recess 428 .

[0174] The third recess 427 and the fourth recess 428 are disposed opposite to each other along a direction perpendicular to the main control board 110 and the mounting cavity 300 .

[0186] In this embodiment, the matching structure of the protective cover 200 and the handle 420 is further defined.

[0187] The inner surface of protective cover 200 is provided with a protrusion 210, which is used to position handle 420 along the direction from vertical plate 144 to bottom plate 142.

This arrangement facilitates the user to identify the type of handle 420 and quickly find the handle 420 that matches the circuit board 410, thereby improving product assembly efficiency and serving as a warning to the user.

[0196] This application eliminates the mounting box used to mount circuit boards in related technologies, and instead positions and assembles the circuit board assembly 400 directly into the mounting cavity 300 enclosed by the watch body 100 and the protective cover 200. This ensures the protection of the circuit board assembly 400 while reducing costs and increasing efficiency, reducing materials, and maintaining functionality.
