In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] In the present invention, Figure 1-7 As shown in the figure, an electric energy meter box is provided, including two boxes 2, the box 2 is a groove-shaped structure with one side open, and the open sides of the two boxes 2 can be assembled together to form a box-shaped structure; the side wall of the box 2 is formed with an insertion cavity 9 perpendicular to the bottom wall of the box 2 near its open side; the part of the side wall of at least one box 2 extending along the splicing direction forms a wire portion 201, and the top of the wire portion 201 is formed with a wire passing notch 11, and the meter box also includes a wire plate 12 that can be assembled on the top of the wire portion 201, the wire plate 12 and the wire portion 201 enclose the wire passing notch 11, and the wire plate 12 Positioning holes 13 and insertion portions 1201 are respectively formed at both ends, the positioning holes 13 correspond to the insertion chamber 9, the box body 2 also includes a pin 10 with two insertion ribs 1001, the two insertion ribs 1001 of the pin 10 can be respectively inserted into two mutually adjacent insertion chambers 9 on the two box bodies 2, and the insertion ribs 1001 of the pin 10 are inserted into the insertion chamber 9 after passing through the positioning holes 13, and the box body 2 is formed with a slot 20 extending perpendicular to the bottom wall of the box body 2, and the insertion portion 1201 can be inserted into the slot 20 to stop the wire board 12 from moving relative to the box body 2 along the bottom wall parallel to the box body 2.

[0029] As shown in the figure, when the meter box of the present invention is in use, the splicing sides of the two boxes 2 are abutted against each other and spliced ​​together, so that the two boxes 2 are spliced ​​together into a box structure. After the electric meter and other electrical components are placed in the box structure, the wires of the electrical components are led out from the wire notch 11, and then the wire board 12 is spliced ​​at the wire part 201, so that the insertion part 1201 is inserted into the slot 20, and then the two insertion ribs 1001 of the pin 10 are respectively inserted into the two adjacent insertion cavities 9 on the two boxes 2, wherein the positioning hole 13 of the wire board 12 is passed through by the insertion rib 1001, so that the pin 10 fixes the two boxes 2 and the wire board 12 at the same time.

[0030] When the box body 2 is damaged, the plug 10 can be pulled out, and then the insertion part 1201 of the wire board 12 can be pulled out of the slot 20, and the wire board 12 can be removed. At this time, the wires of the electrical components can be taken out from the wire notch 11, and the electrical components can be placed between the electrical components and the box body 2. Then the two box bodies 2 are separated, and the damaged box body 2 is removed along the splicing direction, and then the new or repaired box body 2 is moved along the splicing direction so that the two box bodies 2 are spliced ​​again. After the wires of the electrical components are placed in the wire notch 11, the wire board 12 is assembled to the wire part 201, and the plug 10 is inserted into the insertion cavity 9.

[0031] It is not difficult to see that when the metering box of the present invention is in use, the box-like structure containing electrical components is divided into two parts. When the box body 2 is partially damaged, only the corresponding box body 2 needs to be replaced, and there is no need to replace the entire box-like structure, thus saving materials.

[0032] What is particularly important is that the present invention provides two boxes 2. After the entire metering box is installed at the installation position, when it is necessary to remove the box 2, the box 2 to be removed can be separated from the electrical components, and when the box 2 to be removed has a wire-passing notch 11, the wires connected to the electrical components can be led out from the wire-passing notch 11, and then the box 2 can be directly removed. During this process, the wires can be taken out from the wire-passing notch 11, and the relative position between the electrical components and the remaining box 2 remains unchanged, so that the line connection of the electrical components will not be affected by the movement of the electrical components, so that the box 2 can be installed or removed without powering off.

[0033] As shown in the figure, the side wall of the box body 2 is generally in a U-shaped structure. When the two boxes 2 are spliced, the two ends of the side wall are respectively located at the splicing position. The present invention provides the insert rib 1001 and the insert cavity 9. After the boxes 2 are spliced, the two insert ribs 1001 of the latch 10 are respectively inserted into the two insert cavities 9, so that the ends of the side panels of the two boxes 2 can be aligned, further improving the integrity of the installation box, and the two boxes 2 can be limited by the latch 10. The latch 10 can not only align the side panels of the two boxes 2, but also fix the wire board 12.

[0034] The beneficial effect of the present invention is that the plug 10 is inserted into the insertion cavity 9 and passes through the positioning hole 13, so that the plug 10 can simultaneously limit the wire board 12 to prevent the wire board 12 from moving along the splicing direction. Moreover, since the other end of the wire board 12 is inserted into the slot 20 through the insertion portion 1201, the wire board 12 can transmit the restraining force along the splicing direction to the side wall of the box body 2 at the insertion portion 1201, so that the side wall of the box body 2 extending along the splicing direction has two restraining positions, and the restraining force transmission is more uniform, which can keep the side walls of the two boxes aligned. Moreover, by tensioning the wire board 12, the wire board 12 can have a certain pre-tightening effect, which can prevent the box body 2 from loosening at the splicing position and provide a restraining effect on the side wall of the box body 2.

[0035] In one embodiment of the present invention, Figure 2 As shown, more specifically, a panel 1 for installing electrical components is provided, the panel 1 is placed in a boxed structure, the box body 2 is provided with a through slot 3, the panel 1 can be fixed to the wall by bolts passing through the through slot 3, and the panel 1 is connected to the two boxes 2 by bolts. When it is necessary to remove a box body 2, the bolts connecting the panel 1 to the box body 2 can be removed, and then the wire board 12 can be removed, and then the box body 2 to be removed can be removed, and the operation is relatively convenient.

[0036] In the illustrated embodiment, more specifically, the two boxes 2 are respectively formed with a wire portion 201, and after the two boxes 2 are assembled, the wire portions 201 of the two boxes 2 are located on the same side of the box-like structure. As shown in the figure, no wire plate 12 is provided at the other end of the box-like structure, and the plug 10 is directly inserted into the insertion cavity 9.

[0037] It should be noted that this is not intended to limit the present invention, and in an alternative embodiment, a wire portion 201 may be provided at only one side wall of one of the boxes 2 , or a wire portion 201 may be provided at each side wall of each box 2 .

[0038] A further optimization is that a first opening 16 is formed on the side wall of the positioning hole 13 that is open to the box body 2, and the latch 10 further includes a transverse rib 1002 connecting the two inserted ribs 1001. When the latch 10 is inserted into the two positioning holes 13, the transverse rib 1002 passes through the first opening 16. As shown in the figure, specifically, the cross-sectional profile of the positioning hole 13 is roughly L-shaped, and the cross-sectional profile of the latch 10 is U-shaped, thereby preventing the two inserted ribs 1001 of the latch 10 from separating and deforming outwards, which causes the side panels of the two boxes 2 to move relative to each other.

[0039] In the illustrated embodiment, a further optimization is that a second opening 17 is formed on the side wall of the insertion cavity 9 that is open to the box body 2, and when the latch 10 is inserted into the two insertion cavities 9, the transverse rib 1002 passes through the second opening 17. As shown in the figure, the limiting effect of the latch 10 on the side walls of the two boxes 2 can be further improved.

[0040] A further optimization is that, as shown in the figure, the cross section of the insert rib 1001 gradually increases from bottom to top, thereby facilitating the insertion of the latch 10 into the positioning hole 13 and the insertion cavity 9, and, as shown in the figure, the inner surfaces of the two insert ribs 1001 gradually approach from bottom to top, so that during insertion, the side walls of the two boxes 2 can be gradually pulled closer as the latch 10 is inserted downward, and the side walls of the two boxes 2 can be gradually tightened, thereby preventing the side walls of the box 2 from loosening.

[0041] A further optimization is that a positioning groove 18 is formed on the top surface of the wire portion 201, and a positioning rib 19 is formed on the wire plate 12 to be inserted into the positioning groove 18. As shown in the figure, by providing the positioning groove 18, the wire plate 12 can be stably assembled with the box body 2, and the positioning of the wire plate 12 can also be facilitated.

[0042] A further optimization is that one of the boxes 2 is formed with a guide post 4 on its open side, and the other box 2 is formed with a guide hole 5 for the guide post 4 to be inserted; at least one guide post 4 is located at the end of the box 2 close to the insertion cavity 9. The guide post 4 is provided, which not only plays a guiding role when the two boxes 2 are brought close to each other in the splicing direction, so that the two boxes 2 can be aligned, but also after the boxes 2 are spliced, the guide post 4 forms a constraint on the two boxes 2 at the insertion cavity 9 to prevent the two boxes 2 from moving relative to each other in a direction perpendicular to the bottom wall of the box 2, and prevent the bolt 10 from being withdrawn due to the two boxes 2 moving in a direction perpendicular to the bottom wall of the box 2.

[0043] A further optimization is that the side wall of the box body 2 protrudes inward to form a mounting block 6, and the insertion cavity 9 is provided on the mounting block 6. When the two boxes 2 are assembled, the mounting blocks 6 of the two boxes 2 abut against each other. As shown in the figure, by providing the mounting block 6, the structural strength of the side wall of the box body 2 at the insertion cavity 9 can be increased, and the side wall of the box body 2 is prevented from being deformed at the insertion cavity 9, thereby ensuring the alignment of the side wall of the box body 2.

[0044] A further optimization is that the end of the wire board 12 protrudes inward and then extends in a direction away from the wire board 12 to form an insertion portion 1201, and the side wall of the box body 2 protrudes inward to form an insertion block 14, and the insertion block 14 forms a slot 20. As shown in the figure, it is convenient to arrange the insertion block 14 without increasing the thickness of the side wall of the box body 2, and improve the structural strength of the insertion portion 1201 at the insertion position. Moreover, as shown in the figure, the angle between the connecting line of the insertion portion 1201 and the slot 20 abutting position and the connecting line of the insert rib 1001 and the positioning hole 13 and the splicing direction can be made smaller, so that when the wire board 12 is tensioned, the angle between the direction of the tensioning force and the extension direction of the wire board 12 is smaller, so that the wire board 12 can be prevented from being skewed when the plug 10 tensions the wire board 12.

[0045] As for the assembly method of the two box bodies 2, to be more specific, a connecting rib 701 is provided at the edge of the bottom wall of one of the box bodies 2 near its open side, and a snap-in protrusion 702 is formed at the end of the connecting rib 701 away from the box body 2, and the cross-section of the snap-in protrusion 702 is arc-shaped; an arc-shaped snap-in groove 8 is provided at the edge of the bottom wall of the other box body 2 near its open side, and the snap-in protrusion 702 can be squeezed into the inner side of the arc-shaped snap-in groove 8 from the mouth of the arc-shaped snap-in groove 8, and the central angle of the arc-shaped snap-in groove 8 is greater than or equal to 260° and less than or equal to 280°.

[0046] As shown in the figure, the cross section of the arc-shaped slot 8 is smaller than the profile of the snap-in protrusion 702. When the two boxes 2 are assembled, the snap-in protrusion 702 is squeezed in from the slot of the arc-shaped slot 8. In this process, the arc-shaped slot 8 is first stretched and deformed. After the snap-in protrusion 702 is squeezed in, the arc-shaped slot 8 restores its shape and snaps in the snap-in protrusion 702 to achieve the connection of the snap-in structure. When the two boxes 2 are separated, the snap-in protrusion 702 stretches the arc-shaped slot 8 and then separates the snap-in protrusion 702 from the arc-shaped slot 8, so that the two boxes 2 can be separated.

[0047] In order to facilitate the clamping protrusion 702 to enter or squeeze out of the arc-shaped clamping groove 8, while ensuring the clamping force of the arc-shaped clamping groove 8 on the clamping protrusion 702, preferably, the central angle of the arc-shaped clamping groove 8 is greater than or equal to 260° and less than or equal to 280°. In the illustrated embodiment, specifically, the central angle of the arc-shaped clamping groove 8 is set to 270°.

[0048] When in use, a box door 15 as shown in the figure can be provided on the opposite side of the upper bottom plate of the box body 2. After the two boxes 2 are assembled, the box doors 15 of the two boxes 2 can close or open the installation box.

[0049] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0050] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
