Description
Technical Field
[0001] The present application relates to the technical field of electrical equipment, and in particular to a wiring assembly and an electric energy meter. Background Art
[0002] The electric energy meter is a commonly used instrument for measuring electricity and is widely used in various fields such as households and industries. The electric energy meter is generally provided with a terminal box, and a wiring piece is provided in the terminal box. The external wire extends into the wiring piece, and the electrical connection between the electric energy meter and the external wire can be achieved through the wiring piece.
[0003] However, in the prior art, when the external wire is electrically connected to the electric energy meter through the wiring member, the wiring may be unreliable. Utility Model Content
[0004] The present application provides a wiring assembly and an electric energy meter, which can reduce the possibility of the wiring piece moving in the installation hole into the internal space of the electric energy meter, thereby reducing the probability of the problem of unreliable wiring when connecting the external wire and the electric energy meter through the wiring piece.
[0005] In a first aspect, the present application provides a wiring assembly, which is applied to an electric energy meter, and the wiring assembly includes: a terminal box, a wiring member, and a limiter. The terminal box is provided with a mounting hole, and the mounting hole connects the internal space and the external space of the electric energy meter. The wiring member is at least partially arranged in the mounting hole, and the wiring member is provided with a wiring hole, and the wiring hole is used for external wires to extend. The limiter is located on the moving path of the wiring member, and the limiter is used to limit the movement of the wiring member in the mounting hole toward the internal space.
[0006] By means of the above arrangement, a limiter is arranged on the moving path of the wiring member, so that the limiter limits the movement of the wiring member, which can reduce the possibility of the wiring member moving from the mounting hole to the inner space of the electric energy meter when fatigue occurs in the material near the mounting hole, when the electric energy meter moves or bumps, or when the external wire is inserted into the wiring hole. In this way, the problem of the wiring member pressing the internal components of the electric energy meter is reduced, thereby reducing the occurrence of the phenomenon of burning the meter.
[0007] In a possible design, the mounting holes and the wiring members are provided in plurality, and the plurality of mounting holes correspond to the plurality of wiring members one by one. The limiting member includes a connecting section and a plurality of limiting sections, the plurality of limiting sections are connected to the connecting section, the plurality of limiting sections correspond to the plurality of wiring members one by one, and each limiting section is located on the moving path of the corresponding wiring member.
[0008] Through the above arrangement, the number of limiting sections in the limiting member is multiple, and each limiting section is located on the moving path of the corresponding wiring member, which is convenient for limiting multiple wiring members through one limiting member, thereby improving the limiting capacity of the limiting member. There are multiple mounting holes and wiring members, and the multiple mounting holes correspond to the multiple wiring members one by one. In this way, after the wiring members are installed in the mounting holes, it can be avoided that there are no wiring members installed in some mounting holes due to the mismatch between the number of wiring members and the number of mounting holes, thereby causing the sealing of the electric energy meter to deteriorate. In addition, multiple limiting sections are connected to the connecting section, which can make the installation of the limiting sections easier, and it is no longer necessary to install the multiple limiting sections separately, thereby improving the assembly efficiency of the limiting member.
[0009] In a possible design, along the extension direction of the mounting hole, the end of the limiting section away from the connecting section is located between the two ends of the mounting hole. The side wall of the terminal box is provided with a plug hole, the plug hole is connected to the mounting hole, and the limiting section extends into the plug hole.
[0010] Through the above arrangement, a socket connected to the mounting hole is provided on the side wall of the terminal box, and the limiting section is extended into the socket so that the limiting section can be located on the moving path of the wiring member. In this way, when the external wire extends into the wiring hole, even if the external wire applies force to the wiring member so that the wiring member has a tendency to move toward the internal space, it is difficult for the wiring member to bypass the limiting section and move toward the internal space under the restriction of the limiting section. In this way, the possibility of the wiring member moving toward the internal space of the electric energy meter in the mounting hole can be effectively reduced. In addition, the arrangement of the socket allows the limiting section of the limiting member to be inserted into the socket to realize the installation of the limiting member, thereby simplifying the installation process of the limiting member to the wiring member.
[0011] In a possible design, the limiting segment is interference fit with the hole wall of the insertion hole.
[0012] Through the above-mentioned arrangement, the interference fit method can improve the assembly accuracy of the limit piece, ensuring the close contact between the limit section and the hole wall of the socket, secondly, the interference fit method can improve the connection strength between the limit section and the socket, avoiding the limit section from falling out of the socket when the electric energy meter shakes or bumps, thereby causing the limit piece to fail to limit the wiring component, and finally, the interference fit method can also improve the sealing of the electric energy meter, avoiding dust from entering the internal space of the electric energy meter through the gap between the limit section and the socket, thereby increasing the service life of the electric energy meter.
[0013] In a possible design, the limiting section is located at a side of the mounting hole close to the inner space, and the limiting section extends into the mounting hole from the side of the mounting hole close to the inner space.
[0014] Through the above arrangement, the limiting section extends into the mounting hole from the side of the mounting hole close to the internal space of the electric energy meter, so that the limiting member can limit the wiring member from the side of the wiring member close to the internal space of the electric energy meter, reducing the possibility of the wiring member moving along the mounting hole into the internal space of the electric energy meter. In addition, the limiting section is located on the side of the mounting hole close to the internal space, and can directly extend into the mounting hole from the side close to the internal space, so that no additional holes for the limiting section to extend into are required on the terminal box, that is, the structure of the terminal box does not need to be modified to achieve the installation of the limiting member to the mounting hole, so the installation of the limiting member does not increase the manufacturing difficulty of the terminal box.
[0015] In a possible design, the electric energy meter includes a shell, and the limiting member further includes a supporting section, one end of the supporting section is connected to the connecting section, and the other end of the supporting section abuts against the shell.
[0016] Through the above arrangement, one end of the support section is connected to the connection section, and the other end of the support section is in contact with the housing of the electric energy meter, so that the limiter can support the connection section and the limiter through the support section. In this way, the possibility of deformation of the connection section can be reduced, and the possibility of the limiter moving with the deformation of the connection section and no longer being located on the moving path of the wiring member can also be reduced. In this way, the possibility of the limiter failing to limit the wiring member can be reduced, and the limiting effectiveness of the limiter can be improved.
[0017] In a possible design, the limiting member is provided with reinforcing ribs.
[0018] Through the above-mentioned arrangement, since the limit piece is made of insulating material, and since the insulating material often does not have sufficient bending and torsion resistance and is prone to deformation or cracking, reinforcing ribs are provided on the limit piece. The setting of the reinforcing ribs not only improves the load-bearing capacity and durability of the limit piece, but also improves the service life of the limit piece. By setting the reinforcing ribs, the limit piece can withstand a larger load and will not easily break. In this way, there is no need to regularly maintain the limit piece, and the probability of damage to the limit piece is reduced, thereby reducing the frequency of replacing the limit piece and reducing the use cost of the electric energy meter.
[0019] In a second aspect, the present application provides an electric energy meter, comprising a housing and the wiring assembly provided in the first aspect, wherein the wiring assembly is located inside the housing.
[0020] Through the above arrangement, the connection piece is arranged in the housing, and the housing of the electric energy meter can be used to protect the connection piece. In addition, the housing can provide a certain degree of waterproof and dustproof protection for the connection piece, thereby ensuring the service life of the connection piece, reducing the frequency of manual maintenance of the connection piece, and increasing the service life of the electric energy meter.
[0021] In a possible design, a mounting groove is provided at a position of the shell body opposite to the limiting member, and the limiting member is installed in the mounting groove.
[0022] Through the above-mentioned configuration, the limit member is arranged in the installation groove of the shell, and the installation groove can be used to further limit the limit member, thereby avoiding the problem of the limit member shaking when the electric energy meter shakes or the electric energy meter is bumped, which leads to the failure of the limit member to limit the wiring member, thereby ensuring the service life of the electric energy meter.
[0023] The beneficial effects of the electric energy meter provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation method of the first aspect, and will not be repeated here.

[0046] In order to enable those skilled in the art to better understand the solution of the present application, the wiring assembly provided in the embodiment of the present application will be clearly and completely described below in conjunction with the accompanying drawings.
[0047] Figure 1 A schematic diagram of the overall structure of a wiring assembly provided in an embodiment of the present application. Figure 2 for Figure 1 Exploded view of the wiring assembly in Figure 2.
[0048] like Figure 1 and Figure 2 As shown, the present application provides a wiring assembly, which is applied to an electric energy meter. The wiring assembly includes: a terminal box 100, a wiring member 200 and a limit member 300. The terminal box 100 is provided with a mounting hole 110, and the mounting hole 110 connects the internal space and the external space of the electric energy meter. The wiring member 200 is at least partially disposed in the mounting hole 110, and the wiring member 200 is provided with a wiring hole 210, and the wiring hole 210 is used for external wires to extend into. The limit member 300 is located on the moving path of the wiring member 200, and the limit member 300 is used to limit the movement of the wiring member 200 in the mounting hole 110 toward the internal space.
[0049] The terminal box 100 is one of the important components in the electric energy meter. The terminal box 100 has the advantages of electrical insulation, fire prevention and ignition delay. The terminal box 100 is provided with a mounting hole 110, which runs through the terminal box 100, so that the internal space of the electric energy meter is connected with the external space. Among them, the mounting hole 110 can be circular or square, etc. For the convenience of description, the following description will only take the mounting hole 110 as a circular example.
[0050] The terminal block 200 may be partially located in the mounting hole 110 and partially extend outside the mounting hole 110, or the terminal block 200 may be completely located in the mounting hole 110. The terminal block 200 may be cylindrical or prismatic, etc. The drawings and text descriptions of this application are all described by taking the terminal block 200 as a cylindrical shape as an example.
[0051] It should be noted that the shape of the terminal block 200 can be the same as the shape of the mounting hole 110, so that when the terminal block 200 is installed in the mounting hole 110, the terminal block 200 can have a larger contact area with the mounting hole 110, thereby reducing the possibility of the terminal block 200 moving relative to the mounting hole 110. Exemplarily, when the mounting hole 110 is circular, the terminal block 200 can be cylindrical.
[0052] The matching manner between the wiring member 200 and the mounting hole 110 may include the following three situations.
[0053] In the first case, the end face diameter of the connecting member 200 may be slightly larger than the hole diameter of the mounting hole 110. In this case, the connecting member 200 and the mounting hole 110 are interference fit.
[0054] In this matching mode, because the connection between the terminal block 200 and the mounting hole 110 is too tight, it is difficult to install the terminal block 200 into the mounting hole 110. When the terminal block 200 is damaged, it is difficult to replace the terminal block 200. If the terminal block 200 is inserted and removed from the mounting hole 110 many times, fatigue may occur in the material near the mounting hole 110 of the terminal box 100, thereby making the connection between the terminal block 200 and the mounting hole 110 unreliable.
[0055] In the second case, the end face diameter of the wiring member 200 may be equal to the hole diameter of the mounting hole 110. In this case, the wiring member 200 and the mounting hole 110 are clearance-fitted, and the clearance between the wiring member 200 and the mounting hole 110 is zero.
[0056] In the third case, the end face diameter of the wiring member 200 may be smaller than the hole diameter of the mounting hole 110. In this case, the wiring member 200 and the mounting hole 110 are clearance-matched, and the clearance between the wiring member 200 and the mounting hole 110 is greater than zero.
[0057] In the second and third matching modes, although the terminal block 200 and the mounting hole 110 will not cause damage to each other, when the terminal block 200 is installed in the mounting hole 110, the terminal block 200 is easy to fall out of the mounting hole 110 when the electric energy meter shakes or is bumped. Alternatively, when the external wire extends from the external space of the electric energy meter into the wiring hole 210 of the terminal block 200, the external wire may push the terminal block 200 along the axial direction of the mounting hole 110 to the internal space of the electric energy meter. In this way, not only will the sealing performance of the electric energy meter be reduced, but the terminal block 200 may also press the internal components of the electric energy meter and burn the meter.
[0058] In view of this, the present application provides a terminal assembly for an electric energy meter, wherein a limit member 300 is arranged in the terminal assembly, and the limit member 300 is arranged on the moving path of the terminal assembly 200, so as to limit the movement of the terminal assembly 200 by the limit member 300, thereby reducing the possibility of the terminal assembly 200 falling out of the mounting hole 110 when the electric energy meter shakes or is bumped.
[0059] Taking the example of a cylindrical structure of the terminal block 200, a wiring hole 210 for inserting an external wire is provided in the axial direction of the terminal block 200, and at least one threaded hole connected to the wiring hole 210 is provided on the side wall of the terminal block 200. By providing the threaded hole on the side wall of the terminal block 200, when the external wire is inserted into the wiring hole 210, the external wire can be fixed in the terminal block 200 by using a bolt to cooperate with the threaded hole on the side wall of the terminal block 200. It should be noted that the cross section of the terminal block 200 is perpendicular to the axis of the terminal block 200, and the cross sections of the terminal block 200 mentioned below are all perpendicular to the axis of the terminal block 200.
[0060] The limiting member 300 may be in a plate shape or in a column shape, which is not limited in the embodiment of the present application.
[0061] The stopper 300 is installed in the inner space of the electric energy meter, and the stopper 300 is arranged on the moving path of the terminal 200, so as to limit the movement of the terminal 200. The stopper 300 can be made of insulating material, so that while the movement of the terminal 200 is limited by the stopper 300, the stopper 300 will not be electrically connected to the external wire.
[0062] In the embodiment of the present application, a stopper 300 is provided on the moving path of the connection member 200, so that the stopper 300 limits the movement of the connection member 200, which can reduce the possibility of the connection member 200 moving into the inner space of the electric energy meter in the installation hole 110 when fatigue occurs in the material near the installation hole 110, when the electric energy meter moves or bumps, or when the external wire is inserted into the connection hole 210. In this way, the problem of the connection member 300 pressing the internal components of the electric energy meter is reduced, thereby reducing the occurrence of the phenomenon of burning the meter.
[0063] Figure 3 The overall structure diagram of a wiring assembly provided in an embodiment of the present application is shown in FIG. Figures 1 to 3 As shown, the mounting hole 110 and the wiring member 200 can be provided in plurality, and the plurality of mounting holes 110 correspond one-to-one to the plurality of wiring members 200. The limiting member 300 may include a connecting section 310 and a plurality of limiting sections 320, the plurality of limiting sections 320 are connected to the connecting section 310, the plurality of limiting sections 320 correspond one-to-one to the plurality of wiring members 200, and each limiting section 320 is located on the moving path of the corresponding wiring member 200.
[0064] The number of mounting holes 110 needs to be the same as the number of wiring members 200, and when the wiring members 200 are installed in the mounting holes 110, the wiring members 200 need to correspond to the mounting holes 110 one by one. Taking the embodiment of the present application as an example, the number of mounting holes 110 can be 10, and correspondingly, the number of wiring members 200 is also 10.
[0065] The connecting section 310 may be in the shape of a long plate or a long column, etc., and the limiting section 320 may be in any shape such as a plate or a column. One end of each limiting section 320 is integrally connected or detachably connected to the connecting section 310 , and the other end of each limiting section 320 is located on the moving path of the corresponding terminal 200 .
[0066] In summary, there are multiple limiting sections 320 in the limiting member 300, and each limiting section 320 is located on the moving path of the corresponding terminal 200, which facilitates the limiting of multiple terminal 200 by one limiting member 300, thereby improving the limiting ability of the limiting member 300.
[0067] There are multiple mounting holes 110 and wiring members 200, and the multiple mounting holes 110 correspond one-to-one to the multiple wiring members 200. In this way, after the wiring members 200 are installed in the mounting holes 110, it is possible to avoid the problem of no wiring members 200 installed in some mounting holes 110 due to the mismatch in the number of wiring members 200 and mounting holes 110, thereby causing the sealing of the electric energy meter to deteriorate.
[0068] In addition, a plurality of limiting segments 320 are connected to the connecting segment 310 , which can make the installation of the limiting segments 320 easier. There is no need to install the plurality of limiting segments 320 separately, thereby improving the assembly efficiency of the limiting member 300 .
[0069] Figure 4 This is a schematic diagram of the overall structure of a terminal box provided in an embodiment of the present application. Figure 1 , Figure 2 as well as Figure 4 As shown, along the extension direction of the mounting hole 110, the end of the limiting section 320 away from the connecting section 310 is located between the two ends of the mounting hole 110. The side wall of the terminal box 100 is provided with a plug hole 120, which is connected to the mounting hole 110, and the limiting section 320 extends into the plug hole 120.
[0070] The extending direction of the mounting hole 110 is consistent with the axial direction of the aforementioned mounting hole 110 .
[0071] The plug hole 120 is located between the two ends of the mounting hole 110, and the plug hole 120 may have the same shape as the limiting section 320, or may have a different shape from the limiting section 320. For example, the plug hole 120 may be a square hole or a round hole, etc., which is not limited in the present embodiment.
[0072] Through the above arrangement, a socket 120 connected to the mounting hole 110 is arranged on the side wall of the terminal box 100, and the limiting section 320 is extended into the socket 120, so that the limiting section 320 can be located on the moving path of the terminal 200. In this way, when the external wire extends into the wiring hole 210, even if the external wire applies force to the terminal 200, so that the terminal 200 has a tendency to move toward the internal space, under the restriction of the limiting section 320, it is difficult for the terminal 200 to bypass the limiting section 320 and move toward the internal space. In this way, the possibility of the terminal 200 moving toward the internal space of the electric energy meter in the mounting hole 110 can be effectively reduced. In addition, the arrangement of the socket 120 allows the limiting section 320 of the limiting member 300 to be inserted into the socket 120, so that the installation of the limiting member 300 can be realized, thereby simplifying the installation process of the limiting member 300 to the terminal 200.
[0073] Taking the case where the socket 120 is a round hole and the limiting section 320 is cylindrical as an example, in some possible cases, the aperture of the socket 120 may be larger than the diameter of the end of the limiting section 320 away from the connecting section 310. This can avoid the problem that the limiting section 320 cannot be inserted into the socket 120 due to the socket 120 being too small.
[0074] In some other possible cases, the diameter of the insertion hole 120 may be slightly smaller than the diameter of the end of the limiting section 320 away from the connecting section 310 , so that the limiting section 320 and the hole wall of the insertion hole 120 have an interference fit.
[0075] The interference fit method can improve the assembly accuracy of the limit member 300, ensuring that the limit section 320 and the hole wall of the socket 120 can be in close contact. Secondly, the interference fit method can improve the connection strength between the limit section 320 and the socket 120, preventing the limit section 320 from falling out of the socket 120 when the electric energy meter shakes or bumps, thereby causing the limit member 300 to fail to limit the terminal 200. Finally, the interference fit method can also improve the sealing of the electric energy meter, preventing dust from entering the internal space of the electric energy meter from the gap between the limit section 320 and the socket 120, thereby increasing the service life of the electric energy meter.
[0076] In a possible design, the limiting section 320 is located at a side of the mounting hole 110 close to the internal space, and the limiting section 320 extends into the mounting hole 110 from the side of the mounting hole 110 close to the internal space.
[0077] The limiting section 320 may be substantially parallel to the axial direction of the mounting hole 110. After the limiting section 320 extends into the mounting hole 110, it may abut against the side of the wiring member 200 facing the internal space of the electric energy meter, or it may have a certain distance from the side of the wiring member 200 facing the internal space of the electric energy meter. As long as the limiting section 320 extends into the mounting hole 110, it can limit the wiring member 200, and the embodiment of the present application is not limited to this.
[0078] Through the above arrangement, the limiting section 320 extends into the mounting hole 110 from the side of the mounting hole 110 close to the internal space of the electric energy meter, so that the limiting member 300 can limit the terminal 200 from the side of the terminal 200 close to the internal space of the electric energy meter, reducing the possibility of the terminal 200 moving along the mounting hole 110 into the internal space of the electric energy meter. In addition, the limiting section 320 is located on the side of the mounting hole 110 close to the internal space, and can directly extend into the mounting hole 110 from the side close to the internal space, so that no additional holes for the limiting section 320 to extend into are required on the terminal box 100, that is, the structure of the terminal box 100 does not need to be modified to realize the installation of the limiting member 300 to the mounting hole 110, so the installation of the limiting member 300 will not increase the manufacturing difficulty of the terminal box 100.
[0079] Figure 5 A schematic diagram of a combined structure of a bottom shell and a terminal box provided in an embodiment of the present application is shown in FIG. Figure 6 for Figure 5 Exploded view of the mid-shell and terminal box. Figure 7 A schematic diagram of an assembly of a position limiting member provided in an embodiment of the present application is provided. Figure 8 A schematic diagram of the overall structure of a limiter provided in an embodiment of the present application is shown in FIG. Figures 5 to 8 As shown, the electric energy meter includes a shell, and the limiting member 300 also includes a supporting section 330, one end of the supporting section 330 is connected to the connecting section 310, and the other end of the supporting section 330 abuts against the shell.
[0080] The housing includes a top cover and a bottom housing 400, which are covered to form an installation space, and the wiring assembly is installed in the installation space formed by the top cover and the bottom housing 400. The housing is usually made of plastic or other insulating materials, and the housing can provide a certain degree of waterproof and dustproof functions to protect the safe operation of the internal circuits and components of the electric energy meter.
[0081] The support section 330 may be in the shape of a long strip or a long column, etc. The support section 330 may be integrally formed with the connection section 310, or may be separately formed from the connection section 310 and then connected by bonding, snap connection, screw connection, etc. The other end of the support section 330 abuts against the inner bottom surface of the bottom shell 400, thereby supporting the stopper 300.
[0082] The number of support segments 330 may be one. Since the limiting member 300 is made of insulating material, and since the connecting segment 310 needs to connect multiple limiting segments 320, the length of the connecting segment 310 is relatively long. If one support segment 330 is selected to be located in the middle of the connecting segment 310 to support the connecting segment 310, the two ends of the connecting segment 310 may be bent due to gravity or the pressure of the terminal box 100. If two support segments 330 are selected to be located at the two ends of the connecting segment 310 to support the connecting segment 310, the middle part of the connecting segment 310 may be bent due to gravity or the pressure of the terminal box 100. Therefore, the number of support segments 330 may also be multiple.
[0083] Exemplarily, the number of the supporting segments 330 may be three, and the three supporting segments 330 may be respectively located at both ends and the middle of the connecting segment 310 , so as to provide good support for the connecting segment 310 and the limiting segment 320 .
[0084] In summary, one end of the support section 330 is connected to the connection section 310, and the other end of the support section 330 is in contact with the housing of the electric energy meter, so that the position limiting member 300 can support the connection section 310 and the position limiting member 320 through the support section 330. In this way, the possibility of deformation of the connection section 310 can be reduced, and the possibility of the position limiting member 320 moving with the deformation of the connection section 310 and no longer being located on the moving path of the terminal block 200 can also be reduced. In this way, the possibility of the position limiting member 300 failing to limit the terminal block 200 can be reduced, and the limiting effectiveness of the position limiting member 300 is improved.
[0085] Fig. 9 This is an enlarged view of part A provided in the embodiment of the present application. Fig. 9 As shown, the limiting member 300 is provided with reinforcing ribs.
[0086] The reinforcing ribs may be one or more of rectangular ribs, U-shaped ribs, T-shaped ribs and trapezoidal ribs.
[0087] The reinforcing ribs may be provided only on the limiting segment 320 , or may be provided on the limiting segment 320 , the connecting segment 310 and the supporting segment 330 .
[0088] The specific shape requirements, quantity requirements and setting positions of the reinforcement ribs can be selected according to actual design and application requirements. This application does not limit the shape requirements, quantity requirements and setting positions of the reinforcement ribs.
[0089] Since the position-limiting member 300 is made of insulating material, and the insulating material often does not have sufficient bending and torsion resistance and is easily deformed or broken, the present embodiment provides reinforcing ribs on the position-limiting member 300. The provision of the reinforcing ribs not only improves the bearing capacity and durability of the position-limiting member 300, but also improves the service life of the position-limiting member 300. By providing the reinforcing ribs, the position-limiting member 300 can withstand a greater load and will not easily break, so that the position-limiting member 300 does not need to be regularly maintained, and the probability of damage to the position-limiting member 300 is reduced, thereby reducing the frequency of replacing the position-limiting member 300 and reducing the use cost of the electric energy meter.
[0090] Please continue to refer to Figure 7 As shown, a mounting groove 410 is provided at a position of the housing opposite to the limiting member 300 , and the limiting member 300 is installed in the mounting groove 410 .
[0091] The width of the mounting groove 410 can be consistent with the thickness of the limit member 300, so that when the limit member 300 is installed in the mounting groove 410, the side wall of the limit member 300 can contact the groove wall of the mounting groove 410, reducing the possibility of the limit member 300 shaking relative to the mounting groove 410, thereby improving the installation stability of the limit member 300.
[0092] The supporting section 330 in the limiting member 300 is close to the bottom shell 400 of the housing, so the limiting member 300 being installed in the installation groove 410 may refer to the supporting section 330 of the limiting member 300 being installed in the installation groove 410 .
[0093] Through the above-mentioned arrangement, the limit member 300 is arranged in the installation groove 410 of the shell, and the installation groove 410 can be used to further limit the limit member 300, thereby avoiding the limit member 300 from shaking when the electric energy meter shakes or the electric energy meter is bumped, thereby preventing the limit member 300 from failing to limit the wiring member 200, thereby ensuring the service life of the electric energy meter.
