[0013] In this technical solution, it is defined that each cover plate includes two plug-in parts. Specifically, the number of first slots is two, and the two first slots are respectively located on both sides of the width direction of the enclosure. Since the two plug-in parts of one of the cover plates are respectively inserted into the two first slots, that is, the two plug-in parts are distributed along the width direction of the enclosure, that is, one of the cover plates is inserted into the first slots on both sides in the width direction, thereby realizing the assembly of the cover plate.

[0088] like Figure 1 As shown, in some embodiments, optionally, at least one cover plate 120 further includes a groove 124 , and the mounting portion 125 is disposed in the groove 124 .

[0089] In this embodiment, it is defined that at least one cover plate 120 also includes a groove 124. Specifically, the mounting portion 125 is arranged in the groove 124. When the mounting portion 125 is inserted into the mounting groove 111, an avoidance is formed by the groove 124 to avoid the formation of a gap at the connection between the cover plate 120 and the enclosure 110, thereby affecting the reliability and aesthetics of the internal electrical components.

[0090] In some embodiments, optionally, the enclosure plate 110 is an aluminum plate; and / or at least one cover plate 120 is an aluminum plate.

[0091] In this embodiment, specifically, the enclosure 110 is an aluminum plate. Alternatively, at least one cover plate 120 is an aluminum plate. Alternatively, the enclosure 110 and at least one cover plate 120 are both aluminum plates. Alternatively, both cover plates 120 are aluminum plates. Alternatively, the enclosure 110 and both cover plates 120 are aluminum plates. These are not listed here. Specific configurations can be made based on actual needs.

[0092] It is understandable that the aluminum plate is light in weight, which can help reduce the overall weight of the chassis 100 while ensuring the overall structural strength of the chassis 100, making it easier to install and maintain.

[0093] Furthermore, the electrical components of the energy meter are located within the accommodating cavity 130. During operation, these components generate heat. Since at least one of the enclosure 110 and the cover 120 is made of aluminum, the heat dissipation of the energy meter having the chassis 100 during operation can be significantly improved, thereby extending the service life of the energy meter and improving its reliability.

[0110] According to a second aspect of the present invention, an electric energy meter is provided, comprising the chassis 100 provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the chassis 100 , which will not be described in detail herein.

[0111] The chassis 100 includes a surrounding panel 110, two cover panels 120 and at least two slots 140. Specifically, the two cover panels 120 are respectively located on both sides of the surrounding panel 110 in the height direction, and the two cover panels 120 and the surrounding panel 110 are combined to form a accommodating cavity 130, so that the accommodating cavity 130 forms a closed cavity, which is conducive to providing reliable protection for the electrical components of the electricity meter.

Furthermore, this arrangement facilitates assembly and disassembly of the chassis 100 , improves assembly and disassembly efficiency, facilitates subsequent maintenance, and enhances the practicality of the chassis 100 .

[0113] Moreover, the assembly between the two cover plates 120 and the enclosure 110 is achieved by inserting part of the cover plates 120 into the slots 140 , which is conducive to achieving the consistency of the appearance of the chassis 100 and thereby improving the aesthetics of the chassis 100 .
