[0016] Example 1, reference Figure 1-3 A digital meter box structure comprises a box body 1 and a meter 2, a control switch 3, an input line 4 and an output line 5 arranged in the box body 1, wherein the input line 4 and the output line 5 are both composed of a plurality of connection blocks 6 connected by plugging; an incoming connection terminal 11 is arranged at the incoming line port of the box body 1, and an outgoing connection terminal 12 is arranged at the outgoing line port; the incoming connection terminal 11, the input line 4, the control switch 3, the meter 2, the output line 5 and the outgoing connection terminal 12 are assembled and connected in sequence.

[0017] In this embodiment, the input line 4 and the output line 5 in the meter box are composed of a plurality of connection blocks 6, and the incoming connection terminal 11, the outgoing connection terminal 12, the control switch 3 and the meter 2 that can be connected with the connection block 6 are used. The components in the meter box can be spliced ​​and assembled without exposed wires, which can effectively prevent electricity theft while improving the safety performance of the meter box. Specifically, the incoming line connection terminal 11, the connection block 6 of the input line 4, the control switch 3, the meter 2, the connection block 6 of the output line 5 and the outgoing line connection terminal 12 are assembled and connected through a slider slot structure 7, and the connection part of the slider slot structure 7 is electrically connected through a connection contact 71; the slider slot structure 7 is sealed and connected to the component in which it is located, and the inside of the slider slot structure 7 is provided with a connecting wire electrically connected to the connection contact 71. For the connection block 6 constituting the output line 5 and the input line 4, the connecting wire inside the slider slot structure 7 is connected to the connecting contacts 71 at both ends. For the incoming line connection terminal 11, the outgoing line connection terminal 12, the control switch 3 and the meter 2, one end of the connecting wire inside the slider slot structure 7 is connected to the external connection contact 71, and the other end is connected to the inside of the corresponding component.

[0018] Specifically, a plug-in rail 13 is provided in the box 1, and the plug-in rail 13 vertically penetrates the upper and lower ends of the box 1, and the incoming line connection terminal 11, the input line 4, the control switch 3, the meter 2, the output line 5 and the outgoing line connection terminal 12 are plugged into the plug-in rail 13 from bottom to top. By plugging the incoming line connection terminal 11, the input line 4, the control switch 3, the meter 2, the output line 5 and the outgoing line connection terminal 12 in the meter box into the plug-in rail 13, it is convenient to fix and install each component. At the same time, when multiple meter lines need to be installed in the meter box, multiple groups of meter lines can be installed by setting multiple vertical plug-in rails 13, which makes the connection in the meter box simpler and clearer, and is convenient for installation and maintenance of multiple groups of meter lines. In order to facilitate plug-in, the backs of the incoming line connection terminal 11, the control switch 3, the meter 2, the outgoing line connection terminal 12 and the connecting block 6 constituting the input line 4 and the output line 5 are all provided with a slider 14 that cooperates with the plug-in rail 13, so that each component can be fixed on the plug-in rail 13.

[0019] Specifically, a limit block 15 is provided at the upper end of the plug-in rail 13, and a limit latch 16 is provided at the lower end of the plug-in rail 13. The limit block 15 provided at the upper end of the plug-in rail 13 can limit the components installed on the plug-in rail 13, and cooperate with the limit latch 16 at the lower end of the plug-in rail 13. After the components on the plug-in rail 13 are installed, the limit latch 16 can be slid to block the lower end of the plug-in rail 13 and lock it, thereby preventing non-operating personnel from removing the components on the plug-in rail 13, and further preventing electricity theft.

[0020] In addition, an installation opening 17 is provided at the lower end of the box body 1, and the installation opening 17 is aligned with the plug-in rail 13 and can accommodate the incoming line connection terminal 11, the input line 4, the control switch 3, the meter 2, the output line 5 and the outgoing line connection terminal 12. A detachable protective cover plate 18 is provided at the installation opening 17. When installing the components in the meter box, the components can be connected outside first and then directly plugged into the plug-in rail 13 from the installation opening, and then the protective cover plate 18 is sealed at the installation opening 17. In order to facilitate external connection, an inlet port is provided on the protective cover plate 18.

[0021] Specifically, a heat dissipation vent 19 is provided on one side of the box body 1, and the heat dissipation vent 19 includes a back heat dissipation vent 191 close to the back plate of the box body 1 and a front heat dissipation vent 192 close to the front door of the box body 1. The back heat dissipation vent 191 is aligned with the plug-in track 13 fixedly installed on the back of each component, and the front heat dissipation vent 192 is aligned with the space above the front of each component. A heat dissipation bellows 8 is also provided on the side of the box body 1 where the heat dissipation vent 19 is provided, and a heat dissipation fan is provided in the heat dissipation bellows 8. By providing the heat dissipation vent 19 on the side of the box body 1 and using the heat dissipation bellows 8 for exhaust, the components in the meter box can be effectively cooled, and since the components in the meter box are plugged into the plug-in track 13, there is a gap between the components and the back plate of the box body 1, which is more conducive to ventilation and heat dissipation. At the same time, vents 131 are provided at intervals on the side of the plug-in track 13 to further optimize the ventilation and heat dissipation effect.

[0022] Of course, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
