An electric energy meter is an instrument for measuring electric energy, also called watt-hour meter, fire meter, kilowatt-hour meter, and refers to instruments for measuring various electric quantities.
An electric energy meter generally includes a base, a control module disposed in the base, a cover connected to the base, and a communication module disposed in the cover and electrically connected to the control module.
In order to prevent static electricity and ensure safe operation, the communication module is firstly installed in the insulated module box, then the module box is connected with the base, the communication module is simultaneously and electrically connected with the control module through a contact pin in the installation process of the module box, and similarly, the communication module acts on the module box when being disassembled, so that the communication module is separated from the control module and is electrically disconnected. Therefore, when the module box is disassembled and assembled, a user does not directly contact the communication module in the module box, and the safety is higher.
However, the above structure has the following problems: firstly, the cost is high because the module box needs to be arranged; secondly, the processes are more during the disassembly and assembly, for example, during the installation, the communication module is firstly connected with the module box, then the module box is connected with the base, and finally the cover body is connected with the base, three steps of processes are needed for the same disassembly, and the disassembly and assembly are all troublesome.
Thus, improvements may continue.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to prior art's current situation, provide a lower, easy dismounting's of cost electric energy meter.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: an electric energy meter comprises
A base;
the control module is arranged in the base in an up-and-down extending manner;
the cover body is covered on the base and forms an installation space with the base in an enclosing manner;
the communication module extends transversely and is arranged in the installation space, and the communication module is connected with the control module;
the method is characterized in that:
the communication module is connected with the cover body, and the cover body is connected with the base.
In order to facilitate the disassembly and assembly, the communication module is electrically connected with the control module through a contact pin.

The elastic clamping hook is arranged, so that the communication module is convenient to disassemble and assemble, and the elastic clamping hook and the two slots act together, so that the communication module is stably connected with the cover body.
In order to reduce the situation that the base bends the first contact pin in the process of connecting the cover body and the base, a blocking section extending along the vertical direction is arranged in the cover body, and the middle of the blocking section is provided with the slot;
in the left-right direction, the first contact pin is adjacent to the blocking section and is positioned on the inner side of the blocking section;
in the up-down direction, the lower end position of the blocking section is lower than that of the first contact pin.
Through setting up and blockking the section, at the in-process that lid and base link to each other like this, first contact pin is located and blocks the section and the position is higher than and blocks the section and be difficult to contact the base to be difficult to warp because of colliding the base.
Compared with the prior art, the utility model has the advantages of: the communication module is connected with the cover body, so that a communication box is not required to be arranged, and the cost is reduced; when the communication module is installed, the communication module is connected with the cover body, and then the cover body is connected with the base, two installation procedures are needed, the installation procedures are fewer, and similarly, the procedures for disassembling the communication module are fewer.
In the improved scheme, because the first contact pin extends along the up-down direction, the first contact pin is not easy to bend and deform in the process of being inserted into the socket so as to influence the electric connection with the second contact pin;
in addition, generally, in the meter box, the electric energy meter extends along the up-down direction, the space in the meter box in the up-down direction is small, the space in the front-back direction is relatively large, during installation, the installation lug of the cover body is firstly aligned with the front opening in the front-back direction, then the installation lug is inserted into the installation groove along the up-down direction, the moving path of the installation lug is the front-back direction and then the up-down direction, correspondingly, the moving path of the cover body is also the front-back direction and then the up-down direction, similarly, during disassembly, the cover body moves upwards firstly and then moves forwards, so that the moving path of the cover body in the up-down direction is short, and the electric energy meter base is suitable for the situation that the electric energy meter base is positioned in the meter box.
