The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides an anti-theft electric energy meter, such as Figure 1-3 As shown, it includes an anti-theft shell 1, a shell door 2, a locking buckle 3 and an electric energy meter body 6. The shell door 2 is hinged at one end of the anti-theft shell 1, and the locking buckle 3 is provided at one end of the shell door 2. The electric energy meter body 6 is provided inside the anti-theft shell 1; an anti-theft alarm component 5 is provided inside the anti-theft shell 1; the anti-theft alarm component 5 includes an infrared transmitter 52, a mounting plate 53, a sliding seat 54, a lens 55, an infrared receiver 56, a buzzer 57 and a sliding slot 58.
