Description

Technical Field

[0001] The present application relates to the technical field of electrical devices, and in particular to an electric energy meter and an electric energy meter assembly structure. Background Art

[0002] During use, an electric energy meter usually requires a master unit and a slave unit to be connected, wherein the slave unit is used to receive electric energy usage data, and the master unit is used to display the electric energy data.

[0003] Whether it is a master or a slave, the housing is usually provided with a terminal block on the side close to the panel. The terminal block is protected by a cover plate on the housing, and a lead sealing hole is provided on the cover plate. After the electricity meter is installed, the cover plate and the housing are connected by a lead sealing wire passing through the lead sealing hole, making it difficult for non-professionals to open the cover plate, thereby preventing malicious damage to the electricity meter and theft of electricity.

[0004] However, when the electricity meter is in use, there is often another location that may be damaged, namely the electrical connection part between adjacent electricity meters. This location is generally located on the surface where the two electricity meters are spliced, so it is often easily overlooked. Once any electricity meter is removed, this part is directly exposed to the outside, leading to further damage. Utility Model Content

[0005] The present application provides an electric energy meter and an electric energy meter assembly structure, which helps to simultaneously achieve the lead seal between the shell and the meter cover of the electric energy meter and the lead seal between adjacent electric energy meters, thereby realizing the function of protecting two weak structures at the same time with one lead seal structure.

[0006] In a first aspect, the present application provides an electric energy meter, comprising a shell and a meter cover, wherein a connection terminal is provided on the front of the shell, and side panels are provided on opposite sides of the connection terminal, and at least one side panel is provided with a first lead seal hole; the meter cover is connected to the shell and covers the connection terminal, and a second lead seal hole is provided on the meter cover, and the second lead seal hole is at least partially opposite to the first lead seal hole; a third lead seal hole is also provided on the shell and / or the meter cover, and the third lead seal is connected to the first lead seal hole.

[0007] With the electric energy meter provided by the first aspect, the terminal block is used for users to connect the wires when using the electric energy meter. The first lead sealing hole is located on the shell, and the second lead sealing hole is located on the meter cover. When the lead sealing wire passes through the first lead sealing hole and the second lead sealing hole, the shell and the meter cover can be sealed. When multiple electric energy meters are spliced, the sides of adjacent electric energy meters are usually fitted together. At this time, the lead sealing wire can pass through the first lead sealing hole and the second lead sealing hole on one electric energy meter, and then pass through the first lead sealing hole and the second lead sealing hole on another electric energy meter. The two ends of the lead sealing wire then pass through the third lead sealing hole on the two electric energy meters respectively and are connected together. After being connected by the lead sealing structure, not only are the shells and covers of the two adjacent electric energy meters difficult to be maliciously separated, but the two adjacent electric energy meters are also difficult to be separated, thereby protecting the terminal block between the shell and the meter cover, and at the same time, protecting the electrical connection structure between the adjacent electric energy meters, realizing the function of one lead sealing structure to simultaneously protect two weak structures on the two electric energy meters.

[0008] In a possible design, the third lead sealing hole is located on the top surface or the bottom surface of the electric energy meter.

[0009] Through the above solution, the positions where the two ends of the lead sealing wire pass through the electricity meter are located on the top or bottom surface of the electricity meter, avoiding the panel setting of the electricity meter, thereby improving the aesthetics of the electricity meter and not hindering people from operating the buttons on the front of the electricity meter or reading the electricity data from the front of the electricity meter.

[0010] In one possible design, when the third lead sealing hole is located on the top surface of the electricity meter, the distance between the first lead sealing hole and the top surface of the electricity meter is less than one-third of the height of the electricity meter; when the third lead sealing hole is located on the bottom surface of the electricity meter, the distance between the first lead sealing hole and the bottom surface of the electricity meter is less than one-third of the height of the electricity meter.

[0011] Through the above solution, it is convenient for the lead sealing wire to pass through the first lead sealing hole and the second lead sealing hole and then pass out from the third lead sealing hole at a close distance, which is conducive to connecting the lead sealing wire.

[0012] In a possible design, the third lead-sealing hole is arranged opposite to any side of the terminal, so that the wire passes through the third lead-sealing hole.

[0013] Through the above solution, the third lead sealing hole can not only be used for the lead sealing wire to pass through, but also for the wires connected to the terminal to pass through, realizing multiple uses of one hole, reducing the number of features on the electricity meter, and facilitating processing and manufacturing.

[0014] In a possible design, when the first lead sealing holes are provided on both side panels, the third lead sealing hole is communicated with the first lead sealing holes on both side panels.

[0015] Through the above solution, the first lead seal holes on the two side panels are respectively used to connect the electric energy meter with the lead seal of the electric energy meter on the adjacent side, and the third lead seal hole is connected to the first lead seal holes on the two side panels, so that the lead seal wires passing through the two first lead seal holes can all pass out from the same third lead seal hole, further realizing multiple uses of one hole, reducing the number of holes on the electric energy meter, and facilitating the processing and manufacturing of the electric energy meter.

[0016] In one possible design, a hook is protruding from at least one side panel. When multiple electricity meters are spliced together, the hook is inserted into the first lead seal hole on adjacent electricity meters to connect the two electricity meters; the cross-sectional area of the hook perpendicular to the plane of the side panel is smaller than the area of the first lead seal hole.

[0017] With the above solution, when multiple energy meters are spliced together, the hook can be inserted into the first lead-sealing holes on adjacent energy meters, thereby connecting the two meters. This makes the connection between the adjacent energy meters more secure and less likely to be disassembled. The cross-sectional area of the hook, perpendicular to the plane of the side panel, is smaller than the area of the first lead-sealing hole. This ensures that after the hook is connected to the first lead-sealing hole, there is still space for the lead-sealing wire to pass through. This avoids the problem of the hook connection affecting the lead-sealing connection of the energy meter and realizes the multi-purpose use of the first lead-sealing hole.

[0018] In a possible design, the position where the hook is inserted into the first seal hole avoids the area directly facing the second seal hole.

[0019] Through the above solution, after the hook is inserted into the first lead sealing hole, the position of the reserved first lead sealing hole is opposite to the second lead sealing hole, so that the lead sealing wire can directly pass through the first lead sealing hole and the second lead sealing hole without turning, which facilitates the operation of lead sealing connection of the electricity meter.

[0020] In a possible design, an accommodating gap is provided between the end surfaces of the first lead-sealing hole and the second lead-sealing hole that are close to each other, and the accommodating gap is used to accommodate a hook when multiple electric energy meters are spliced together.

[0021] With the above solution, after the hook is inserted into the first lead sealing hole, it is located in the accommodation gap, thereby not affecting the connection between the meter cover and the shell, and the space allocation of various structures of the electric energy meter is more reasonable.

[0022] In the second aspect, the present application provides an assembly structure of an electric energy meter, including multiple electric energy meters and lead sealing wires. The electric energy meter can be the structure of any of the above-mentioned embodiments, and multiple electric energy meters are spliced together; the lead sealing wire passes through and connects two groups of lead sealing holes on two adjacent electric energy meters in sequence, and each group of lead sealing holes includes a first lead sealing hole, a second lead sealing hole and a third lead sealing hole located on the same electric energy meter.

[0023] Through the above solution, when assembling multiple electricity meters, the two ends of the lead seal wire are passed through the two groups of lead seal holes and then connected. As a result, in the assembly structure of the electricity meter, not only are the shells and covers of the two adjacent electricity meters difficult to be maliciously separated, but the two adjacent electricity meters are also difficult to be separated, thereby protecting the wiring terminals between the shells and the covers, and at the same time, protecting the electrical connection structure between the adjacent electricity meters, thereby realizing the function of one lead seal structure protecting two weak structures on the two electricity meters at the same time.

[0024] In one possible design, multiple electricity meters are spliced and arranged in a straight line, with a female plug provided on one side of the electricity meter at the head end, a male plug provided on one side of the electricity meter at the tail end, a male plug provided on one side of the electricity meter in the middle, and a female plug provided on the other side, and two adjacent electricity meters are connected through the male plug on one electricity meter and the female plug on the other electricity meter; wherein, the electricity meter in the middle is any one of the electricity meters between the electricity meter at the head end and the electricity meter at the tail end.

[0025] With this solution, when multiple energy meters are connected, any two adjacent energy meters can be connected by plugging the male and female plugs together, enabling signal transmission between the adjacent energy meters. After the multiple energy meters are sealed and connected, any one of the energy meters is difficult to disassemble, thus preventing the male and female plugs between any two adjacent energy meters from being damaged or maliciously connected.

[0026] Other beneficial effects of the assembly structure of the electric energy meter provided in the above-mentioned second aspect and various possible designs of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and various possible implementation methods of the first aspect, and will not be repeated here.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 3The present application provides an electric energy meter, including a housing 100 and a meter cover 200. A connection terminal 400 is provided on the front face a of the housing 100. Side plates 110 are provided on opposite sides of the connection terminal 400, and at least one side plate 110 is provided with a first lead sealing hole 120; the meter cover 200 is connected to the housing 100 and covers the connection terminal 400. A second lead sealing hole 210 is provided on the meter cover 200, and the second lead sealing hole 210 is at least partially opposite to the first lead sealing hole 120; a third lead sealing hole 300 is also provided on the housing 100 and / or the meter cover 200, and the third lead seal is connected to the first lead sealing hole 120.

[0042] The housing 100 is the outermost part of the energy meter. It contains a storage space within which the meter's main functional components and detection components are located. The housing 100 can be a single component or a composite component. For example, in some embodiments, the housing 100 includes two half-shell structures. Before the meter is fully assembled, components can be installed in one of the half-shell structures. Once all components are in place, the openings of the two half-shell structures are butt-jointed and fastened together to complete the housing 100. The composite component configuration of the housing 100 facilitates the installation of other components within the housing 100.

[0043] The front side a of the shell 100 refers to the side of the shell 100 used to display electric energy parameters or perform debugging operations on the electric energy meter. The connection terminal 400 is set on the front side a of the shell 100, and the opposite sides of the connection terminal 400 refer to the side surfaces on both sides of the front side a of the electric energy meter.

[0044] The terminal block 400 is used by the user to connect the wires when using the electricity meter. Therefore, the terminal block 400 is generally exposed to the outside to facilitate the user's wiring operation. If the user does not properly protect this part after wiring, dust and moisture may enter, causing the terminal block 400 to age. It is also possible that the connection between the terminal block 400 and the wire is artificially damaged. In the worst case, the electricity meter will not monitor the electricity usage accurately. In the worst case, electricity theft will occur, resulting in energy loss to the national power grid.

[0045] The meter cover 200 covers the terminal block 400 and reserves a hole and slot structure for the wires to enter and exit. The meter cover 200 and the shell 100 are connected in a detachable structure, so that the user can remove the meter cover 200 when wiring and reconnect the meter cover 200 to the shell 100 after wiring.

[0046] For example, Figure 2As shown, in some embodiments, the watch cover 200 is arranged between the two side panels 110, and limiting buckles 220 are provided on both sides of the watch cover 200. A limiting groove 130 is provided on the side where the two side panels 110 are close to each other. After the watch cover 200 and the shell 100 are assembled, the limiting buckles 220 are located in the limiting groove 130, thereby realizing the limitation of the watch cover 200 and the shell 100, and also facilitating the disassembly of the watch cover 200 and the shell 100.

[0047] The first lead sealing hole 120 is set on the side plate 110 on the watch cover 200, wherein the first lead sealing hole 120 can be set on only one side plate 110, or on both side plates 110, which is not limited in this embodiment of the present application.

[0048] The second sealing holes 210 are used in conjunction with the first sealing holes 120. Therefore, the positions and number of the second sealing holes 210 also correspond one-to-one with the first sealing holes 120. That is, when one first sealing hole 120 is provided on each of the two side panels 110, two second sealing holes 210 are also provided on the watch cover 200. The two second sealing holes 210 respectively correspond to the positions of one first sealing hole 120, and the second sealing holes 210 are at least partially opposite to the corresponding first sealing holes 120, so that the sealing thread 900 passes through the one-to-one corresponding first and second sealing holes 120, 210. When one of the side panels 110 is provided with a first sealing hole 120, one second sealing hole 210 is also provided on the watch cover 200, and the second sealing hole 210 corresponds to the position of the first sealing hole 120, and the second sealing hole 210 is at least partially opposite to the corresponding first sealing hole 120.

[0049] The third sealing hole 300 is provided on the housing 100 or the cover 200. Alternatively, the housing 100 and the cover 200 may jointly form the third sealing hole 300. The third sealing hole 300 is communicated with the first sealing hole 120. Correspondingly, the third sealing hole 300 is also communicated with the second sealing hole 210, so that the sealing thread 900 can pass through the first sealing hole 120, the second sealing hole 210, and the third sealing hole 300.

[0050] In the above solution, since the first sealing hole 120 is located on the housing 100 and the second sealing hole 210 is located on the cover 200, when the sealing wire 900 passes through the first sealing hole 120 and the second sealing hole 210, the housing 100 and the cover 200 can be sealed.

[0051] Please continue to refer to Figure 4 and Figure 5When multiple electric energy meters are spliced together, the sides of adjacent electric energy meters are usually attached together. At this time, the lead sealing wire 900 can pass through the first lead sealing hole 120 and the second lead sealing hole 210 on one electric energy meter, and then pass through the first lead sealing hole 120 and the second lead sealing hole 210 on another electric energy meter. The two ends of the lead sealing wire 900 then pass through the third lead sealing hole 300 on the two electric energy meters respectively and are connected together. After being connected by this lead sealing structure, not only the housing 100 and the meter cover 200 of the two adjacent electric energy meters are difficult to be maliciously separated, but the two adjacent electric energy meters are also difficult to be separated, thereby protecting the terminal 400 between the housing 100 and the meter cover 200, and at the same time, protecting the electrical connection structure between the adjacent electric energy meters, realizing the function of one lead sealing structure to simultaneously protect two weak structures on the two electric energy meters.

[0052] like Figure 1 、 Figure 2 and Figure 3 As shown, in a possible design, the third lead sealing hole 300 is located on the top surface b or the bottom surface c of the electric energy meter.

[0053] The top surface b or bottom surface c is relative to the front surface a of the energy meter, and is adjacent to the front surface a and distinct from the two side surfaces of the energy meter. During installation and use, the top surface b of the energy meter is generally facing upward along the direction of gravity, and the bottom surface c of the energy meter is generally facing downward along the direction of gravity.

[0054] According to the description of the threading method of the lead sealing wire 900 in the aforementioned scheme, it can be seen that the exit positions of the two ends of the lead sealing wire 900 are the third lead sealing holes 300. In this embodiment, the third lead sealing hole 300 is located on the top surface b or the bottom surface c of the electric energy meter, so that the positions where the two ends of the lead sealing wire 900 pass through the electric energy meter are located on the top surface b or the bottom surface c of the electric energy meter, avoiding the panel setting of the electric energy meter, thereby improving the aesthetics of the electric energy meter and not hindering personnel from operating the buttons on the front a of the electric energy meter or reading electric energy data from the front a of the electric energy meter.

[0055] In one possible design, when there are multiple connection terminals 400 on the electricity meter, if the connection terminals 400 at different locations are close to each other, the same meter cover 200 can be used to simultaneously seal and protect the multiple connection terminals 400. If the connection terminals 400 at different locations are far apart, a meter cover 200 can be used for each of them, and each meter cover 200 can seal one of the connection terminals 400.

[0056] For example, the electricity meter includes two connecting terminals 400, one connecting terminal 400 is close to the top surface b of the electricity meter, and the other connecting terminal 400 is close to the bottom surface c of the electricity meter. The electricity meter then includes two meter covers 200, one of which is arranged on the front side a of the shell 100 close to the top surface b, and the other meter cover 200 is arranged on the front side a of the shell 100 close to the bottom surface c.

[0057] In the case where the above-mentioned electric energy meter is provided with multiple meter covers 200, side plates 110 are provided on both sides of each terminal 400, and a first lead sealing hole 120 is provided on at least one of the side plates 110. Correspondingly, a second lead sealing hole 210 is provided on each meter cover 200 to achieve a lead sealing connection between the housing 100 and the meter cover 200.

[0058] In one possible design, when the third lead sealing hole 300 is located on the top surface b of the electric energy meter, the distance between the first lead sealing hole 120 and the top surface b of the electric energy meter is less than one-third of the height of the electric energy meter; when the third lead sealing hole 300 is located on the bottom surface c of the electric energy meter, the distance between the first lead sealing hole 120 and the bottom surface c of the electric energy meter is less than one-third of the height of the electric energy meter.

[0059] The height of the electricity meter refers to the distance from the top surface b to the bottom surface c of the electricity meter.

[0060] The above arrangement allows the position of the first sealing hole 120 to be different according to the position of the third sealing hole 300, satisfying the principle that the first sealing hole 120 is closer to the surface where the third sealing hole 300 is located. Therefore, when the sealing wire 900 is passed through, it is convenient for the sealing wire 900 to pass through the first sealing hole 120 and the second sealing hole 210 and then pass out from the third sealing hole 300 at a close distance, which is conducive to connecting the sealing wire 900 in the first sealing hole 120, the second sealing hole 210 and the third sealing hole 300.

[0061] like Figure 2 As shown, in a possible design, the third lead sealing hole 300 is arranged opposite to any side of the connection terminal 400, so that the wire passes through the third lead sealing hole 300.

[0062] When the electric energy meter is connected to a circuit, one end of the wire is connected to the terminal block 400, and the other end is connected to an external circuit. Therefore, it is necessary to provide a hole and slot structure for the wire to pass through on the housing 100 and / or the meter cover 200. In the above-mentioned solution of the present application, the third lead-sealing hole 300 is arranged opposite to either side of the terminal block 400, so that the wire can pass through the third lead-sealing hole 300 at a close distance, realizing the multi-purpose use of the third lead-sealing hole 300. There is no need to additionally process a hole and slot for the wire to pass through on the electric energy meter, thereby reducing the number of features on the electric energy meter and facilitating processing and manufacturing.

[0063] Optionally, when the connection terminals 400 are arranged in a row, the third lead sealing hole 300 may be arranged in a long strip shape so as to be directly opposite to the row of connection terminals 400 at the same time.

[0064] In a possible design, when the first sealing holes 120 are provided on both side panels 110 , the third sealing hole 300 is communicated with the first sealing holes 120 on both side panels 110 .

[0065] The first lead sealing holes 120 on the two side panels 110 are respectively used to connect the electric energy meter to the electric energy meter seal on the adjacent side, and the third lead sealing hole 300 is connected to the first lead sealing holes 120 on the two side panels 110, so that the lead sealing wires 900 passing through the two first lead sealing holes 120 can all pass out from the same third lead sealing hole 300, further realizing multiple uses of one hole, reducing the number of holes on the electric energy meter, and facilitating the processing and manufacturing of the electric energy meter.

[0066] Optionally, the third sealing hole 300 can be longer so that the sealing wire 900 can pass through the third sealing hole 300 from the end close to the first sealing hole 120, thereby reducing the difficulty of connecting the sealing wire 900. The location of the portion between the two ends of the sealing hole is not limited.

[0067] In some embodiments, the third sealing hole 300 is arranged opposite to either side of the terminal 400 so that the wire passes through the third sealing hole 300 , and the third sealing hole 300 is connected to the first sealing holes 120 on both side panels 110 .

[0068] In the above arrangement, the third sealing hole 300 can be made longer, allowing the sealing wire 900 to pass through the third sealing hole 300 from the end closest to the first sealing hole 120, reducing the difficulty of connecting the sealing wire 900. At the same time, the middle of the third sealing hole 300 is directly opposite to either side of the terminal block 400. With this arrangement, the third sealing hole 300 is not only used to connect the sealing wire 900 at two locations, but can also be used to pass wires, further realizing the multi-purpose use of the third sealing hole 300.

[0069] Please refer to Figure 3 、 Figure 4 and Figure 5 In one possible design, a hook 500 is protruding from at least one side plate 110. When multiple electricity meters are spliced together, the hook 500 is inserted into the first lead-sealing hole 120 on adjacent electricity meters to connect the two electricity meters. The cross-sectional area of the hook 500 perpendicular to the plane of the side plate 110 is smaller than the area of the first lead-sealing hole 120.

[0070] The hook 500 performs a preliminary connection on the electric energy meters when two electric energy meters are spliced together, so that two adjacent electric energy meters can be connected through the hook 500, realizing multiple connections between the electric energy meters and further reducing the possibility of non-specific personnel intentionally damaging and disassembling the electric energy meters.

[0071] The hook 500 is inserted into the first lead sealing hole 120 on the adjacent electric energy meter to connect the two electric energy meters. Therefore, the connection of the hook 500 does not require an additional hole to be opened on the electric energy meter, but is achieved through the first lead sealing hole 120, thereby realizing the reuse of the first lead sealing hole 120.

[0072] The cross-sectional area of the hook 500 perpendicular to the plane of the side plate 110 is smaller than the area of the first seal hole 120, so that after the first seal hole 120 is connected to the hook 500, there is still space for the seal wire 900 to pass through, avoiding the problem of the hook 500 connection affecting the seal connection of the electricity meter.

[0073] Please refer to Figure 5 In a possible design, the position where the hook 500 is inserted into the first seal hole 120 avoids the area directly facing the second seal hole 210.

[0074] Through the above solution, after the hook 500 is inserted into the first lead sealing hole 120, the reserved position of the first lead sealing hole 120 is opposite to the second lead sealing hole 210, so that the lead sealing wire 900 can directly pass through the first lead sealing hole 120 and the second lead sealing hole 210 without turning, which facilitates the operation of sealing the electric energy meter.

[0075] Please continue to refer to Figure 5 In a possible design, an accommodating gap 600 is provided between the end surfaces of the first lead sealing hole 120 and the second lead sealing hole 210 that are close to each other. The accommodating gap 600 is used to accommodate the hook 500 when multiple electric energy meters are spliced together.

[0076] The adjacent end surfaces of the first and second sealing holes 120 and 210 are actually adjacent surfaces of the side panel 110 and the watch cover 200. The accommodation gap 600 can be a pre-set gap between the side panel 110 and the watch cover 200 during assembly, or it can be a recessed structure provided in the side panel 110 or the watch cover 200, forming the accommodation gap 600. This embodiment of the present application is not limited to this, as long as the space provided in the accommodation gap 600 is sufficient to accommodate the hook 500.

[0077] Through the above solution, after the hook 500 is inserted into the first lead sealing hole 120, it is located in the accommodating gap 600, so that the connection of the hook 500 will not affect the connection between the meter cover 200 and the housing 100, and the space allocation of various structures of the electric energy meter is more reasonable.

[0078] like Figure 4As shown, the present application also provides an assembly structure of an electric energy meter, which includes multiple electric energy meters and a lead sealing wire 900. The electric energy meter can be the electric energy meter structure in any of the above embodiments, and multiple electric energy meters are spliced together; the lead sealing wire 900 passes through and connects two groups of lead sealing holes on two adjacent electric energy meters in sequence, and each group of lead sealing holes includes a first lead sealing hole 120, a second lead sealing hole 210 and a third lead sealing hole 300 located on the same electric energy meter.

[0079] Through the above solution, when assembling multiple electric energy meters, the two ends of the lead seal wire 900 are passed through the two groups of lead seal holes and then connected, so that in the assembly structure of the electric energy meter, not only the housing 100 and the meter cover 200 of each of the two adjacent electric energy meters are difficult to be maliciously separated, but also the two adjacent electric energy meters are difficult to be separated, thereby protecting the connection terminal 400 between the housing 100 and the meter cover 200, and at the same time, protecting the electrical connection structure between the adjacent electric energy meters, thereby realizing the function of one lead seal structure to simultaneously protect two weak structures on the two electric energy meters.

[0080] Please refer to Figures 1 to 4 In a possible design, multiple electricity meters are spliced and arranged in a straight line. A female plug 800 is provided on one side of the electricity meter at the head end, a male plug 700 is provided on one side of the electricity meter at the tail end, and a male plug 700 is provided on one side of the electricity meter in the middle and a female plug 800 is provided on the other side. Two adjacent electricity meters are connected by connecting the male plug 700 on one electricity meter with the female plug 800 on the other electricity meter; wherein, the electricity meter in the middle is any electricity meter between the electricity meter at the head end and the electricity meter at the tail end.

[0081] For example, when five electric energy meters are spliced, the first electric energy meter is the electric energy meter located at the head end, the fifth electric energy meter is the electric energy meter located at the tail end, and the second, third, and fourth electric energy meters are the electric energy meters located in the middle.

[0082] Among them, the electricity meter located at the head end can be the electricity meter host, and the electricity meters located at the tail end and in the middle can be the electricity meter slaves. The electricity meter host is provided with a visual window for reading electrical signals through the visual window. The electricity meter slave may not be provided with a visual window, and it only needs to serve the function of measuring electrical signals.

[0083] When multiple energy meters are connected, any two adjacent meters can be connected by plugging the male plug 700 and the female plug 800 together, enabling signal transmission between the adjacent meters. After the multiple meters are sealed and connected, any one meter is difficult to disassemble, thus preventing the male plug 700 and the female plug 800 between any two adjacent meters from being damaged or maliciously connected.

[0084] Other beneficial effects of the assembly structure of the electric energy meter provided in the various possible designs of the assembly structure of the electric energy meter can be found in the above-mentioned possible implementation methods of the electric energy meter and the beneficial effects brought about, which will not be repeated here.

[0085] In summary, the embodiment of the present application provides a first lead sealing hole 120 on the housing 100 and a second lead sealing hole 210 on the meter cover 200. When the lead sealing wire 900 passes through the first lead sealing hole 120 and the second lead sealing hole 210, the housing 100 and the meter cover 200 can be sealed. When multiple electric energy meters are spliced, the lead sealing wire 900 can pass through the first lead sealing hole 120 and the second lead sealing hole 210 on one electric energy meter, and then pass through the first lead sealing hole 120 and the second lead sealing hole 210 on another electric energy meter. The two ends of the lead sealing wire 900 are respectively passed through the third lead sealing holes 300 on the two electric energy meters and then connected together. After being connected through the lead sealing structure, not only the housing 100 and the meter cover 200 of the two adjacent electric energy meters are difficult to be maliciously separated, but the two adjacent electric energy meters are also difficult to be separated, thereby protecting the connection terminal 400 between the housing 100 and the meter cover 200, and at the same time, protecting the electrical connection structure between the adjacent electric energy meters, realizing the function of one lead sealing structure to simultaneously protect two weak structures on the two electric energy meters.
