It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] An electric energy meter is an instrument used to measure electric energy. It is also called an electric meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities.

[0030] The electric energy meter in the related art has the problem of poor sealing, which cannot effectively prevent dust, liquid and other foreign matter from entering the electric energy meter, interfering with the normal operation of the internal components of the electric energy meter and shortening the service life of the electric energy meter.

[0031] Based on this, in order to improve the problems in the related art, the embodiments of the present application provide the following solutions.

[0032] Please also read Figures 1 to 4 The embodiment of the present application provides a dustproof electric energy meter, including a shell 1, a rotating shaft 2, a cover plate 3 and a wiring assembly. The wiring assembly is arranged on the shell 1 for connecting with the wire. The rotating shaft 2 is rotatably connected to the shell 1. The cover plate 3 is rotatably connected to the shell 1 through the rotating shaft 2. A first groove 11 is formed on the shell 1, and a second groove 31 is formed on the cover plate 3. A wire threading hole 5 is formed between the first groove 11 and the second groove 31.

[0033] From the above, it can be seen that a dustproof electricity meter provided in an embodiment of the present application is provided with a cover plate 3 with a dustproof function. When closed, the cover plate 3 is tightly closed with the shell 1, which can greatly enhance the airtightness of the electricity meter, effectively prevent external dust, liquid and other foreign matter from entering the interior of the electricity meter, ensure the normal operation of the electricity meter and increase its service life.

[0034] In some embodiments, please refer to Figures 1 to 3 An annular gasket 6 is connected to the threading hole 5, and a dent is formed on the inner ring surface of the annular gasket 6.

[0035] With such arrangement, the annular pad 6 will fit tightly with the wire when the cover 3 is closed, further enhancing the overall airtightness of the electric energy meter. The indentation can increase the friction between the wire and the annular pad 6, preventing the external wire from loosening due to external force, thereby fixing the wire.

[0036] Optionally, in some embodiments, see Figure 1 A first clamping strip 12 is disposed on the housing 1 , and a second clamping strip 32 is disposed on the cover plate 3 . The first clamping strip 12 abuts against the second clamping strip 32 .

[0037] With such arrangement, when the cover plate 3 is closed, the first clamping strip 12 and the second clamping strip 32 abut against each other to fix the cover plate 3, thereby avoiding the situation where the cover plate 3 is difficult to open and close due to the use of screws to fix the cover plate 3.

[0038] Optionally, see Figures 1 to 4 The wiring assembly includes a wire sleeve 41 and a connecting wire 42. The wire sleeve 41 is arranged on the shell 1. The wire sleeve 41 has an internal threading hole 411. A first voltage connecting plate 7 is arranged in the wire sleeve 41. A second voltage connecting plate 8 is also slidably connected in the wire sleeve 41. One end of the connecting wire 42 is connected to the first voltage connecting plate 7, and the other end of the connecting wire 42 is connected to the shell 1.

[0039] With such arrangement, the internal wire threading hole 411 allows the wire to pass through the wire sleeve 41 and be connected to the wiring assembly, and the first voltage connecting piece and the second voltage connecting piece can ensure that the wire is reliably connected to the wiring assembly.

[0040] Optionally, see Figures 1 to 4 A positioning plate 412 is provided at one end of the wire sleeve 41 away from the shell 1, and a through hole 413 is opened on the positioning plate 412. The wiring assembly also includes a sliding rod 43 and a spring 44. The sliding rod 43 passes through the through hole 413 and is connected to the second voltage-connecting plate 8. The spring 44 is sleeved on the sliding rod 43, and one end of the spring 44 abuts against the positioning plate 412, and the other end of the spring 44 abuts against the second voltage-connecting plate 8.

[0041] With such arrangement, when connecting the wire 42 to the wiring assembly, the staff can use the sliding rod 43 to conveniently lift the second voltage connecting plate 8 and place the wire between the first voltage connecting plate 7 and the second voltage connecting plate 8. After releasing the sliding rod 43, the spring 44 rebounds to ensure that the second voltage connecting plate 8 tightly crimps the wire onto the first voltage connecting plate 7.

[0042] Optionally, see Figure 4A handle 45 is also provided at one end of the sliding rod 43 away from the first voltage-connecting plate 7 .

[0043] With such arrangement, the staff can use the handle 45 with the help of the sliding rod 43 to pull up the second voltage connecting piece 8 more easily and labor-savingly, thereby avoiding the difficulty for the staff to pull up the second voltage connecting piece 8 due to the sliding rod 43 being too thin and the spring 44 having a large elastic force.

[0044] Optionally, see Figure 4 The first voltage-connecting plate 7 and the second voltage-connecting plate 8 are both provided with teeth, and the teeth on the first voltage-connecting plate 7 can mesh with the teeth on the second voltage-connecting plate 8 .

[0045] With such arrangement, the teeth can ensure that the first voltage connecting plate 7 and the second voltage connecting plate 8 tightly bite the wire, preventing the connection between the wire and the wiring assembly from loosening due to external factors, thereby reducing the conductivity of the wire and the wiring assembly, causing the wire and the wiring assembly to heat up and affect the working efficiency of the electric energy meter or even cause spontaneous combustion.

[0046] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
