[0041] In the related art, existing electricity meters all adopt a built-in battery structure, which requires the design of an independent connection component or battery box to protect the battery. The built-in battery structure occupies a large space on the electricity meter PCB board, resulting in reduced utilization of the PCB board, increased volume of the electricity meter, and increased production and manufacturing costs of the electricity meter.
[0042] Based on this, this embodiment installs the connecting component 400 in the second installation cavity 120, so that the connecting component 400 is located outside the first installation cavity 110, and can be externally placed with a battery 700. The battery is installed in the accommodating groove, and the connecting component 400 does not occupy the space of the PCB board 500. It can improve the space utilization of the PCB board 500 and reduce the overall volume of the shell assembly, thereby reducing the production and manufacturing cost of the electric energy meter.
[0043] Reference Figures 1 to 3 Combined with Figure 7 , Figure 1 and Figure 3 All of them are structural schematic diagrams of an electric energy meter according to an embodiment of the present utility model, wherein: Figure 3 The second body 300 is hidden in the Figure 2 This is an exploded schematic diagram of an electric energy meter according to an embodiment of the present utility model. Figure 7 This is a schematic structural diagram of a seat body 100 according to an embodiment of the present invention. Figure 3 、 Figure 7 As shown, the shell assembly of this embodiment includes a base body 100, a cover body assembly and a connecting assembly 400. The base body 100 is provided with a first mounting cavity 110 and a second mounting cavity 120 which are separated from each other. The PCB board 500 is installed in the first mounting cavity 110, and the connecting assembly 400 is installed in the second mounting cavity 120. The connecting assembly 400 is provided with a receiving groove 401, and the battery 700 is installed in the receiving groove 401. The PCB board 500 and the battery 700 are separated from each other. The cover body assembly is covered on the base body 100, and the cover body assembly blocks the first mounting cavity 110 and the second mounting cavity 120, so that the connecting assembly 400 does not occupy the space of the PCB board 500, which can reduce the overall volume of the shell assembly, thereby reducing the production cost of the electric energy meter.
[0044] It should be noted that the battery 700 is electrically connected to the PCB board 500 so that the battery 700 can supply power to the PCB board 500 so that the PCB board 500 can operate normally, which will not be described in detail here.
[0045] In this embodiment, the cover assembly includes a first body 200 and a second body 300. The first body 200 blocks the first installation cavity 110, and the second body 300 blocks the second installation cavity 120, which can improve the waterproof and dustproof performance of the shell assembly.
[0046] For example Figure 2 As shown, the base 100 and the first body 200 can be connected in a detachable manner, which can facilitate opening the first installation cavity 110 to facilitate users to replace or maintain the PCB board 500.
[0047] For example, the seat body 100 and the first body 200 are detachably connected by bolting, or one side of the first body 200 is hingedly connected to the seat body 100, and the opposite side of the first body 200 is clamped to the seat body 100 to limit the rotation of the first body 200 in the direction of opening the first mounting cavity 110, so that the user can exert an external force on the first body 200 to facilitate opening or closing the first mounting cavity 110, which will not be described here.
[0048] Of course, in other embodiments, the seat body 100 and the first body 200 can also be connected by welding, and the welding seam extends circumferentially along the seat body 100 to improve the waterproof performance between the seat body 100 and the first body 200, wherein the welding method includes but is not limited to ultrasonic welding, laser welding, resistance welding, etc., which will not be described here.
[0049] In this embodiment, the second body 300 is detachably connected to the first body 200, and when the battery 700 fails, the user can detach the second body 300 to open the second mounting cavity 120 to facilitate replacement of the battery 700.
[0050] For example, the second body 300 is connected to the first body 200 by a fastener (not shown), the fastener is threaded through the second body 300 and is threadedly connected to the first body 200 to stably connect the second body 300 to the first body 200, which is more convenient to install and detach, and is conducive to replacing the battery 700. The fastener can be a bolt or a screw, which is not limited here.
[0051] As another embodiment, the second body 300 can also be connected to the first body 200 by a first clamping structure, for example, the first clamping structure can be a structure in which a first clasp cooperates with a first clamping groove, one of the first clasp and the first clamping groove is provided on the second body 300, and the other is provided on the first body 200, the first clasp is accommodated in the first clamping groove and can abut against the side wall of the first clamping groove, and the detachable connection of the second body 300 to the first body 200 can also be achieved.
[0052] Of course, in other embodiments, the second body 300 can also be detachably connected to the seat body 100, and the second body 300 can be detachably connected to the seat body 200 by the fastener or the first clamping structure described above, which will not be described here. In addition, the second body 300 can also be rotatably connected to the seat body 100, and when the second body 300 rotates, the second mounting cavity 120 is opened or closed, which also facilitates replacement of the battery 700, which will not be described here.
[0053] As another embodiment, the second body 300 and the first body 200 can also be an integrated structure. The second body 300 and the first body 200 can be integrally formed by injection molding, which can reduce the number of molds, thereby reducing the production cost of the molds and thus reducing the production cost of the housing assembly. In addition, the second body 300 and the first body 200 can also be connected by welding, which will not be repeated here.
[0054] Reference Figures 4 to 6 , Figure 4 This is a structural diagram of the first body 200 of an embodiment of the present utility model. Figure 5 for Figure 4 A top view of Figure 6 for Figure 5 A partial enlarged view of part A. Figure 4 、 Figure 5 As shown, in this embodiment, the connecting component 400 includes a first clamping member 410 and a second clamping member 420 provided on the first main body 200, and the first clamping member 410 and the second clamping member 420 are arranged opposite to each other to enclose and form a receiving groove 401. Portions of the outer peripheral surface of the battery 700 are respectively abutted against the first clamping member 410 and the second clamping member 420, so that the battery 700 can be interference fit with the receiving groove 401, so that the battery 700 can be stably installed in the receiving groove 401, which can simplify the structure of the connecting component 400 and eliminate the need for an additional battery box, thereby reducing the production cost of the electric energy meter.
[0055] It should be noted that the notch of the receiving groove 401 is away from the base 100. When installing the battery 700, the assembler can insert the battery 700 from top to bottom, which can simplify the assembly process of the battery 700 and thus improve the assembly efficiency of the electric energy meter.
[0056] As another embodiment, the first clamping member 410 and the second clamping member 420 can also be arranged on the wall of the second installation cavity 120, or the first clamping member 410 and the second clamping member 420 are arranged on the second main body 300, so that the connecting component 400 can be arranged on the outside of the first installation cavity 110, and there is no limitation here.
[0057] As another embodiment, the connecting component 400 may also include a connecting member, one end of the connecting member is connected to the first clamping member 410, the other end of the connecting member is connected to the second clamping member 420, and the side of the connecting member away from the first connecting member 410 is connected to the first main body 200, which can facilitate the connection and fixation of the first clamping member 410 and the second clamping member 420, which will not be repeated here.
[0058] As another embodiment, the connecting component 400 can also be a connecting block. One side of the connecting component 400 is recessed to form a container 401. The battery 700 is installed in the container 401, which can also facilitate the installation and fixing of the battery 700. No further details will be given here.
[0059] For example Figure 4 As shown, it can be understood that the first clamping member 410, the second clamping member 420 and the first body 200 are an integrated structure, which can reduce the number of molds to reduce the production cost of the molds, thereby reducing the production cost of the housing assembly.
[0060] For example, the first clamping member 410, the second clamping member 420 and the first main body 200 can be integrally formed by injection molding, that is, the first clamping member 410, the second clamping member 420 and the first main body 200 are an integrated plastic part, and the plastic part has higher structural strength, strong corrosion resistance and durability.
[0061] Of course, in other specific embodiments, the first clamping member 410, the second clamping member 420 and the first main body 200 can also be connected by welding, which can facilitate the fixing of the first clamping member 410 and the second clamping member 420. The welding method includes but is not limited to resistance welding, ultrasonic welding or laser welding, etc., which will not be repeated here.
[0062] For example Figure 5 、 Figure 6 As shown, in this embodiment, the first clamping member 410 includes a first connecting portion 411, a first clamping portion 412 and a first supporting portion 413, one side of the first connecting portion 411 is connected to the first clamping portion 412, the other side opposite to the first connecting portion 411 is connected to the first body 200, the first supporting portion 413 is connected to the side of the first clamping portion 412 close to the accommodating groove 401, the second clamping member 420 includes a second connecting portion 421, a second clamping portion 422 and a second supporting portion 423, one side of the second connecting portion 421 is connected to the second clamping portion 422, the second connecting portion 421 is connected to the second clamping portion 422, The other side opposite to the connecting portion 421 is connected to the first main body 200, the second supporting portion 423 is connected to the side of the second clamping portion 422 close to the accommodating groove 401, the first clamping portion 412 and the second clamping portion 422 are enclosed to form the accommodating groove 401, the first supporting portion 413 and the second supporting portion 423 are both accommodated in the accommodating groove 401 to support one end of the battery 700, and can position the battery 700 axially. When one end of the battery 700 abuts against the first supporting portion 413 and the second supporting portion 423, the battery 700 is installed in place, which can facilitate the assembly of the battery 700.
[0063] It should be noted that the first supporting portion 413 is extended in a direction close to the second clamping portion 422, and the second supporting portion 423 is extended in a direction close to the first clamping portion 412. The first supporting portion 413 and the second supporting portion 423 are spaced apart to form a avoidance opening, which is used to avoid the wires connected to one end of the battery 700 so that the wires can be led out from the bottom of the accommodating groove 401. On the one hand, it can facilitate the arrangement of the lines of the battery 700, and on the other hand, it can simplify the structure of the connecting component 400.
[0064] For example Figure 6 As shown, in this embodiment, a first reinforcing rib 430 is provided between the first connecting portion 411 and the first body 200. One side of the first reinforcing rib 430 is connected to the first body 200, and the other adjacent side of the first reinforcing rib 430 is connected to the side of the first connecting portion 411 facing away from the second connecting portion 421. This can improve the structural strength of the first clamping member 410, thereby enhancing the structural stability of the first clamping member 410, reducing bending deformation of the first clamping member 410, and thus increasing the service life of the first clamping member 410. In addition, the number of first reinforcing ribs 430 can be configured as one or more. The greater the number of first reinforcing ribs 430, the higher the structural strength of the first clamping member 410.
[0065] Similarly, a second reinforcing rib 440 is provided between the second connecting portion 421 and the first body 200. One side of the second reinforcing rib 440 is connected to the first body 200, and the other adjacent side of the second reinforcing rib 440 is connected to the side of the second connecting portion 421 facing away from the first connecting portion 411. This improves the structural strength and stability of the second clamping member 420, reduces bending deformation of the second clamping member 420, and thereby increases the service life of the second clamping member 420. Furthermore, the number of second reinforcing ribs 440 can be configured as one or more. A greater number of second reinforcing ribs 440 increases the structural strength of the second clamping member 420.
[0066] It should be noted that the first reinforcing rib 430 can also be connected to the side of the first connection part 411 facing the second connection part 421, and the second reinforcing rib 440 can also be connected to the side of the second connection part 421 facing the first connection part 411, as long as the structural strength of the first clamping member 410 and the second clamping member 420 can be improved, and no limitation is made here.
[0067] For example Figure 6As shown, in order to limit the circumferential movement of the battery 700 in the accommodating groove 401 along the circumferential direction of the accommodating groove 401, two limiting portions 450 are provided in the portion of the first main body 200 located between the first clamping member 410 and the second clamping member 420. The two limiting portions 450 are arranged side by side and spaced apart in the direction from the first connecting portion 411 to the second connecting portion 421, and the limiting portions 450 are extended along the axial direction of the accommodating groove 401. When the battery 700 is installed in the accommodating groove 401, the outer peripheral surface of the battery 700 abuts against the limiting portions 450, which can limit the circumferential movement of the battery 700 along the accommodating groove 401, so as to circumferentially position the battery 700, thereby improving the installation stability of the battery 700.
[0068] It should be noted that the number of the limiting parts 450 can be one or three, etc., which is not limited here.
[0069] In this embodiment, a rounded corner structure is provided at one end of the stopper 450 near the notch of the receiving groove 401. The rounded corner structure can reduce interference between the battery 700 and the stopper 450, thereby guiding the battery 700 into the receiving groove 401 and facilitating installation of the battery 700. Of course, in other specific embodiments, the rounded corner structure can be replaced with a chamfered structure, which will not be described in detail here.
[0070] In this embodiment, the battery 700 is configured as a cylindrical battery 700. Along the direction perpendicular to the axial direction of the accommodating groove 401, the cross-section of the accommodating groove 401 corresponds to a circular structure, so that the first clamping portion 412 and the second clamping portion 422 can cover the outer peripheral surface of the battery 700, so as to increase the contact area between the first clamping portion 412 and the second clamping portion 422 and the battery 700, thereby improving the installation stability of the battery 700.
[0071] It should be noted that the side of the first clamping portion 412 away from the first connecting portion 411 and the side of the second clamping portion 422 away from the second connecting portion 421 are spaced apart to form a gap 402, so that the first clamping member 410 and the second clamping member 420 are elastic, and the first clamping member 410 and the second clamping member 420 can produce slight deformation to clamp the battery 700, which can improve the installation stability of the battery 700.
[0072] When the battery 700 is configured as a square battery 700 , the cross section of the receiving groove 401 along a direction perpendicular to the axial direction of the receiving groove 401 is correspondingly a square structure, which can adapt to batteries 700 of different shapes.
[0073] In order to prevent the battery 700 from exiting the receiving groove 401 from the notch 402, the width of the receiving groove 401 first increases and then decreases in the direction from the first connecting portion 411 to the first clamping portion 412, and the width of the notch 402 is designed to be smaller than the maximum width of the receiving groove 401. When the battery 700 has a tendency to exit the receiving groove 401 from the notch 402, the outer peripheral surface of the battery 700 can abut against the side wall of the receiving groove 401 to limit the movement of the battery 700, so that the battery 700 cannot exit the receiving groove 401 from the notch 402, which can improve the installation stability of the battery 700.
[0074] It should be noted that along the first direction, the first clamping member 410 and the second clamping member 420 are arranged opposite each other. The width of the notch 402 refers to the size of the notch 402 in the first direction, and the width of the receiving groove 401 refers to the size of the receiving groove 401 in the first direction. The first direction can be the up-down direction or the width direction of the first body 200, which will not be further described here.
[0075] The electric energy meter of the second embodiment of the present utility model includes the housing assembly of the above embodiment.
[0076] The electric energy meter of the second embodiment of the utility model adopts the shell assembly of the first embodiment. By installing the connecting assembly 400 in the second installation cavity 120, the connecting assembly 400 is located outside the first installation cavity 110, and the external battery 700 can be placed. The connecting assembly 400 does not occupy the space of the PCB board 500, which can improve the space utilization of the PCB board 500 and reduce the overall volume of the shell assembly, thereby reducing the production cost of the electric energy meter.
[0077] Reference Figure 2 、 Figure 8 , Figure 8 The figure is a schematic diagram of the structure of a battery 700 according to an embodiment of the present invention. Based on the second embodiment of the present invention, the electric energy meter further includes a PCB board 500 and a battery 700. The PCB board 500 is mounted in the first mounting cavity 110 and is provided with a conductive socket 510. The battery 700 is mounted in the second mounting cavity 120 and is connected to a conductive plug 710. The conductive plug 710 is plugged into the conductive socket 510. This simplifies the electrical connection assembly between the battery 700 and the PCB board 500, eliminating the need for copper sheets and springs to achieve electrical connection between the battery 700 and the PCB board 500. This reduces the number of components in the electric energy meter, thereby improving the assembly efficiency of the electric energy meter.
[0078] It should be noted that the positive pole of the battery 700 is connected to the first wire 720, and the negative pole of the battery 700 is connected to the second wire 730. The first wire 720 and the second wire 730 are both connected to the conductive plug 710. The conductive socket 510 is set on the PCB board 500. The conductive socket 510 is provided with a first conductive pin and a second conductive pin. The first conductive pin and the second conductive pin are respectively connected to the first wire 720 and the second wire 730, so that the battery 700 can power the PCB board 500.
[0079] It is understandable that the notch 402 can also avoid the second wire 730 and prevent the second wire 730 from interfering with the connecting assembly 700 , thereby facilitating replacement of the battery 700 .
[0080] It should be noted that a second latching structure is provided between the conductive socket 510 and the conductive plug 710 to facilitate installation and removal of the conductive plug 710, thereby making it easier for the user to replace the battery 700. For example, the second latching structure can be a structure in which a second latch and a second latching slot cooperate, with one of the second latch and the second latching slot being provided on the inner wall of the conductive socket 510, and the other being provided on the conductive plug 710. The second latch is received in the second latching slot and can abut against the side wall of the second latching slot, thereby achieving a detachable connection between the second body 300 and the base 100.
[0081] It should be noted that in this embodiment, the electric energy meter also includes a communication module 600. The communication module 600 is installed in the second mounting cavity 120 and is electrically connected to the PCB board 500. The communication module 600 can realize data transmission and communication connection between devices, and can rationally utilize the space within the second mounting cavity 120 to reduce the overall volume of the housing assembly, thereby reducing the production cost of the electric energy meter. It is understood that the communication module 600 can be a 3G communication module or a 4G communication module, which will not be further described here.
[0082] It should be pointed out that in this embodiment, the connecting assembly 400 and the communication module 600 are spaced apart along the width direction of the base body 100, which can reasonably utilize the space in the second installation cavity 120 to reduce the length of the base body 100, thereby reducing the overall volume of the shell assembly and reducing the production cost of the shell assembly.
[0083] In order to simplify the structure of the base body 100, an avoidance hole 210 is opened on the side of the first main body 200 facing the PCB board 500, and the conductive socket 510 is located directly below the avoidance hole 210. The conductive plug 710 can pass through the avoidance hole 210 from top to bottom and be plugged into the conductive socket 510. On the one hand, there is no need to open a hole on the outer peripheral side of the base body 100 to avoid the conductive plug 710, which can facilitate the production of the base body 100. On the other hand, it can simplify the assembly steps of the battery 700 to improve the assembly efficiency of the electric energy meter.
[0084] It should be noted that when the second main body 300 blocks the second installation cavity 120, the second main body 300 also blocks the avoidance hole 210, which can prevent the conductive plug 710 from being exposed to the outside world, thereby preventing external dust or rainwater from entering the first installation cavity 110 through the avoidance hole 210, and improving the waterproof and dustproof performance of the electric energy meter.
[0085] It should be noted that the avoidance hole 210 and the accommodating groove 401 are both close to the same side of the first body 200, which can shorten the distance between the battery 700 and the avoidance hole 210, thereby reducing the length of the first wire 720 and the second wire 730, thereby saving the material cost of the energy meter.
[0086] For example Figure 2 As shown, the conductive socket 510 is located at a corner of the PCB board 500 , which can reduce the space occupied by the conductive socket 510 on the PCB board 500 , thereby facilitating the installation of electrical components such as mutual inductors on the PCB board 500 .
[0087] In this embodiment, a first positioning groove 121 is provided on a side of the second mounting cavity 120 away from the first main body 200, and a second positioning groove 220 is provided on the side of the first main body 200 away from the first clamping member 410 along the direction from the first clamping member 410 to the second clamping member 420. One side of the circuit board of the communication module 600 is partially accommodated in the first positioning groove 121, and the other adjacent side of the circuit board of the communication module 600 is accommodated in the second positioning groove 210. The circuit board of the communication module 600 can be in contact with the first positioning groove 121, and the circuit board of the communication module 600 can be abutted against the side wall of the second positioning groove 210 to position the communication module 600 in the up and down directions and in the width direction of the first main body 200. The communication module 600 can be positioned in a two-dimensional direction, thereby facilitating the installation of the communication module 600.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
