[0025] Embodiment

[0026] This embodiment provides an anti-stealing electricity energy meter. The energy meter includes a housing 1 and a cover plate 2 disposed above the housing 1. A wiring base 3 is provided below the housing 1. A connection cover 4 capable of preventing electricity stealing is disposed above the wiring base 3. A buckling structure 5 is provided between the wiring base 3 and the connection cover 4. The buckling structure 5 includes a positioning strip 51 disposed on one side of the wiring base 3 or the connection cover 4 and a positioning groove 52 disposed on the other side and capable of allowing the positioning strip 51 to be inserted and wrapping the positioning strip 51.

[0027] The above specific improvement is as follows: As Figure 1 and Figure 2 shown, compared with the prior art, after the energy meter is installed, covering the cover plate 2 outside the wiring base 3 below the housing 1 can wrap the wiring base 3. The wiring base 3 is arranged in sequence with the incoming line of the live wire, the outgoing line of the live wire, the incoming line of the neutral wire, and the outgoing line of the neutral wire. After all the wires are installed, they can be directly connected into the distribution box, and all the wiring terminals are wrapped in the connection cover 4 and will not be exposed outside. In this way, it can effectively prevent the wire arrangement at the wiring terminals from being illegally tampered with to cause electricity stealing. Through the setting of the positioning strip 51 and the positioning groove 52 adapted thereto, when installing the connection cover 4, snapping the positioning strip 51 into the positioning groove 52 can make the connection cover 4 completely wrap outside the wiring base 3, preventing someone from illegally tampering with the circuit.

[0028] Based on the above embodiment: The positioning strip 51 is disposed on the connection cover 4. An extension plate 6 is provided at the housing 1. The positioning groove 52 is opened at the extension plate 6 and the opening of the positioning groove 52 faces downward. An extension block 7 for an external fastening nail to pass through is provided on the wiring base 3. An extension groove 71 wrapping the extension block 7 is provided on the connection cover 4. The connection cover 4 has a first position where the extension block 7 and the extension groove 71 are separated and a second position where the extension groove 71 wraps outside the extension block 7.

[0029] The above specific improvement is as follows: As Figure 4 and Figure 5As shown in the figure, the positioning strip 51 is provided on the connection cover 4. An extension plate 6 is provided on one side of the housing 1 connected to the wiring base 3. A positioning groove 52 is opened in the extension plate 6, and the opening of the positioning groove 52 faces downward. When installing the connection cover 4, insert the positioning strip 51 from below the extension plate 6. Then the operator presses against the wiring base 3 with the thumb, and then presses the connection cover 4 downward, so that the extension groove 71 on the connection cover 4 crosses the limit of the extension block 7, so that the extension groove 71 can completely wrap the extension cover (at this time, the connection cover 4 is in the second position). When the connection cover 4 needs to be removed, the extension groove 71 on the connection cover 4 needs to cross the limit of the extension block 7 before the connection cover 4 can be removed (at this time, the connection cover 4 is in the first position).

[0030] Based on the above embodiment: An extension ring 21 is wrapped around the periphery of the cover plate 2. A wrapping groove 22 for wrapping the buckling structure 5 is provided inside the extension ring 21. The extension ring 21 can abut against the upper end surface of the connection cover 4.

[0031] The above specific improvement is as follows: As Figure 4 and Figure 5 shown in the figure, an extension ring 21 is wrapped around the outside of the cover plate 2. When the positioning groove 52 is inserted into the positioning groove 52 and the connection cover 4 is wrapped around the outside of the wiring board, cover the cover plate 2 above the housing 1. The wrapping groove 22 below the extension ring 21 of the cover plate 2 will wrap the buckling structure 5, so that the connection cover 4 cannot be removed, achieving the effect of lead sealing.

[0032] Based on the above embodiment: The wiring base 3 has a plurality of receiving grooves 31 for receiving wiring terminals. A groove 32 for leading out the meter reading wire is provided between the receiving grooves 31. An outlet hole 8 for leading out the meter reading wire is provided on the side surface of the connection cover 4.

[0033] Based on the above embodiment: The connection cover 4 includes a first connecting plate 41, a second connecting plate 42, and a guiding inclined surface 43 provided between the two. The positioning strip 51 is provided at the first connecting plate 41. The second connecting plate 42 extends toward the side opposite to the first connecting plate 41.

[0034] The above specific improvement is as follows: As Figure 2 and Figure 3As shown in the figure, four receiving grooves 31 are provided on the terminal block 3. The four receiving grooves 31 are respectively connected to the live wire inlet, the live wire outlet, the neutral wire inlet, and the neutral wire outlet. An inlet end for receiving the meter reading wire is provided between the live wire inlet and the live wire outlet, and an outlet end for receiving the meter reading wire is provided between the neutral wire inlet and the neutral wire outlet. The outlet end (that is, the 485 wire, whose function is to realize data communication between the electric energy meter and the upper computer (such as a concentrator, a meter reading system) through the RS-485 protocol) is led out externally through the outlet hole 8 on the side of the connecting cover 4. Therefore, when reading the electric energy meter, it is not necessary to disassemble the terminal block 3. The connecting cover 4 includes a first connecting plate 41, a second connecting plate 42, and a guiding inclined surface 43 provided between the two. Through the setting of the guiding inclined surface 43, it can effectively guide water bodies or other impurities to fall, thereby preventing them from accumulating on the connecting cover 4.

[0035] Based on the above embodiments: A through groove 9 for guiding the wire into the meter box is provided between the terminal block 3 and the connecting cover 4.

[0036] The above specific improvement is as follows: As Figure 2 shown in the figure, the wire led out from the terminal block 3 can be directly connected into the distribution box through the through groove 9. In this way, when the connecting cover 4 is covered, the outside cannot contact these wires, thus achieving the effect of preventing electricity theft.

[0037] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
