DETAILED DESCRIPTION

[0043] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides an electrical installation board 1, the electrical installation board 1 includes at least two board bodies 11 and at least one plug-in structure 4 arranged at adjacent ends of the two board bodies 11, the plug-in structure 4 includes a plurality of limiting structures 41 and a plurality of stop structures 42 respectively arranged at the two board bodies 11, the plurality of limiting structures 41 are sequentially distributed along a first direction, and the plurality of stop structures 42 are respectively arranged corresponding to the plurality of limiting structures 41;

[0044] Among them, at least one limiting structure 41 is configured as a slot structure 122, and at least one stop structure 42 is configured as a plug-in structure 121 corresponding to the slot structure 122; when the plug-in structure 121 is inserted into the slot structure 122, two adjacent limiting structures 41 are suitable for respectively limiting the corresponding two stop structures 42 along the thickness direction of the plate body 11 (i.e. Figure 1 and Figure 2 The Z-axis direction in the figure moves toward both ends.

[0045] It should be noted that the structure of the plate body 11 is not limited, and it may have a certain thickness or a cavity, and it only needs to be able to arrange the multiple limiting structures 41 or the stop structures 42 .

[0046] For example, Figure 1 and Figure 2 As shown, the two plate bodies 11 are distributed along the left-right direction (i.e., the X-axis direction in the figure) to Figure 1 The plate body 11 located on the left side (negative direction of the X-axis) is the left plate body, and the plate body 11 located on the right side (positive direction of the X-axis) is the right plate body. An end of the left plate body close to the right plate body (i.e., the end located in the positive direction of the X-axis) is connected to a plurality of limiting structures 41, and an end of the right plate body close to the left plate body (i.e., the end located in the opposite direction of the X-axis) is connected to a plurality of stop structures 42.

[0047] The plug-in structure 121 is inserted into the corresponding slot structure 122 along the left-right direction (i.e., the X-axis direction in the figure), and the side walls of the slot structure 122 along the width direction (i.e., the side walls along the front-to-back direction) can limit the displacement of the corresponding plug-in structure 121 along the front-to-back direction, that is, it can limit the displacement of the left plate body and the right plate body along the front-to-back direction.

[0048] When the plug-in structure 121 is inserted into the corresponding slot structure 122, the side walls of the slot structure 122 along the thickness direction of the board body 11 (i.e., the side walls located in the Z-axis direction, that is, the side walls located in the up and down directions) can limit the displacement of the corresponding plug-in structure 121 along the thickness direction (i.e., the displacement along the Z-axis direction).

[0049] It should be noted that the specific structures of the limiting structure 41 and the stopper structure 42 are not limited. When the plug-in structure 121 is inserted into the corresponding slot structure 122, the setting of the limiting structure 41 and the stopper structure 42 can realize the interaction to limit the movement along the thickness direction of the plate body 11. Specifically, one of the two adjacent limiting structures 41 is suitable for limiting the corresponding stopper structure 42 from moving toward one end along the thickness direction of the plate body 11, and the other of the two adjacent limiting structures 41 is suitable for limiting the corresponding stopper structure 42 from moving toward the other end along the thickness direction of the plate body 11.

[0050] It should be noted that after the electrical installation board 1 is installed in the box body 2, the box body 2 will be hung on the wall as a whole. At this time, the Y-axis direction is consistent with the up and down direction in the space. Therefore, the limiting along the Y-axis direction and the limiting along the Z-axis direction between adjacent plate bodies 11 are necessary and practical, which can improve the reliability of the electrical installation board 1 and will not be described in detail here.

[0051] The advantage of such a setting is that when the plug-in structure 121 is inserted into the corresponding slot structure 122, the side wall of the slot structure 122 along the first direction (i.e., the side wall in the width direction) forms a limit on the corresponding plug-in structure 121, which can avoid the relative movement of the two adjacent plate bodies 11 along the first direction; and the two adjacent limiting structures 41 are suitable for respectively limiting the movement of the corresponding two stop structures 42 toward both ends along the thickness direction of the plate body 11, and the movement between the two plate bodies 11 along the thickness direction of the plate body 11 toward both ends is restricted, and a stable plug-in is formed between the two plate bodies 11; and the plug-in method is easy to assemble and has strong practicality, and can realize the modular design of the electrical installation board 1. The electrical installation board 1 will no longer be limited to a fixed size and can be assembled according to actual needs, reducing the difficulty of processing, transportation, storage and other links. In the field of electrical appliances, especially in multi-meter modular metering boxes, the number of electric energy meter positions may need to be adjusted according to the actual number of users. Through the assembly design, the electrical installation board 1 can be assembled according to needs and ensure its firmness, avoiding safety hazards such as the falling of the plate body 11, and has high application value.

[0052] like Figure 1 As shown, optionally, the plug-in structure 4 includes at least three limiting structures 41 and at least three stop structures 42 .

[0053] Exemplarily, at least one of the three limiting structures 41 located in the middle is set as a slot structure 122, and at least one of the three stop structures 42 located in the middle is set as a plug-in structure 121. When the plug-in structure 121 is inserted into the corresponding slot structure 122, the slot structure 122 limits the movement of the plug-in structure 121 along the thickness direction of the plate body 11 toward one end (for example, toward the end in the positive direction of the Z axis), and the two limiting structures 41 adjacent to the slot structure 122 both limit the movement of the corresponding two stop structures 42 along the thickness direction of the plate body 11 toward the other end (for example, toward the end in the opposite direction of the Z axis).

[0054] The advantage of such a setting is that when the plug-in structure 121 is inserted into the slot structure 122, due to the restrictions of the two adjacent limiting structures 41, the corresponding two stop structures 42 move in opposite directions. The three limiting structures 41 and the three stop structures 42 respectively contact with each other to form limits, and the whole body engages with each other, so that the structure of the plug-in structure 4 is stable and the reliability is high.

[0055] In the embodiment of the present invention, all the limiting structures 41 are configured as slot structures 122, and all the stop structures 42 are configured as plug-in structures 121. This situation will be taken as an example to explain the content of the present invention.

[0056] like Figure 2 As shown, in the present specification, three plug-in connection structures are respectively a first plug-in connection structure 12, a second plug-in connection structure 13 and a third plug-in connection structure 14, and the first plug-in connection structure 12, the second plug-in connection structure 13 and the third plug-in connection structure 14 are sequentially distributed along a first direction (for example, sequentially distributed along the positive direction of the Y-axis) to illustrate the contents of the present invention.

[0057] Exemplarily, the slot structure 122 of the first plug-in connection structure 12 limits the corresponding plug-in structure 121 from moving in the negative direction of the Z axis, and the slot structure 122 of the second plug-in connection structure 13 limits the corresponding plug-in structure 121 from moving in the positive direction of the Z axis. The slot structure 122 of the third plug-in connection structure 14 limits the corresponding plug-in structure 121 from moving in the negative direction of the Z axis. Thus, there is a limit for movement toward both ends along the up and down directions between the left plate body and the right plate body, and its implementation method will be described in detail later. The slot structure 122 is arranged at one end of the plate body 11 and protrudes from the plate body 11 along the insertion direction of the plug-in structure 121. The slot structures 122 can be arranged at intervals (not shown in the figure), and correspondingly, the plug-in structures 121 are also arranged at intervals. Of course, it is not limited to this, and will be described in detail later.

[0058] like Figures 1 to 4As shown, in the embodiment of the present invention, one end of the slot structure 122 along the thickness direction of the plate body 11 is set as an opening structure 1221, and the openings of the opening structures 1221 of two adjacent slot structures 122 face opposite directions.

[0059] Exemplarily, the opening directions of the opening structures 1221 of the slot structures 122 of the first plug-in connection structure 12 and the third plug-in connection structure 14 are both toward the positive direction of the Z axis, and the opening direction of the opening structure 1221 of the slot structure 122 of the second plug-in connection structure 13 is toward the negative direction of the Z axis. The plug-in structures 121 are arranged at intervals, and the plug-in structures 121 are inserted into the slot structures 122 to form a box structure.

[0060] like Figure 2 and Figure 4 As shown, specifically, the side wall of the slot structure 122 of the first plug-in connection structure 12 located in the negative direction of the Z axis contacts the side wall of the corresponding plug-in structure 121 located in the negative direction of the Z axis, so as to limit the movement of the plug-in structure 121 along the negative direction of the Z axis, that is, to limit the movement of the plug-in structure 121 toward the side close to the bottom plate of the box body 2. The side wall of the slot structure 122 of the second plug-in connection structure 13 located in the positive direction of the Z axis contacts the side wall of the corresponding plug-in structure 121 located in the positive direction of the Z axis, so as to limit the movement of the plug-in structure 121 along the positive direction of the Z axis, that is, to limit the movement of the plug-in structure 121 away from the bottom plate of the box body 2. The situation of the third plug-in connection structure 14 is similar to that of the first plug-in connection structure 12, and will not be described in detail here, so that the left side plate body and the right side plate body are firmly connected in the thickness direction.

[0061] At this time, the opening size of the opening structure 1221 can be greater than or equal to the size of the plug-in structure 121. Along the thickness direction of the board body 11, the plug-in structure 121 can be set as a stepped structure to enhance its structural rigidity, or it can be a plug-in structure, which is not a limitation. Exemplarily, when the plug-in structure 121 is inserted into the corresponding slot structure 122, the plug-in structure 121 is at least partially accommodated in the opening structure 1221 and is flush with the edge of the opening structure 1221.

[0062] The advantage of such a configuration is that the slot structure 122 will not be limited to having only an insertion port for inserting the plug-in structure 121. The configuration of the opening structure 1221 facilitates the insertion of the plug-in structure 121. A box body structure with a stable connection is formed through the deformation of the contact surfaces of the plug-in structure 121 and the slot structure 122. Multiple box body structures together realize the connection between the two board bodies 11. In addition, the space required for arranging the slot structure 122 can be reduced to a certain extent, which can save materials and reduce costs. The structure is simple and practical.

[0063] like Figure 2 and Figure 4As shown, in the embodiment of the present invention, two adjacent slot structures 122 are staggered, and two adjacent plug-in structures 121 are staggered and correspondingly inserted into the two adjacent slot structures 122 .

[0064] like Figure 4 As shown, taking the arrangement of the plug-in structure 121 as an example, the plug-in structure 121 of the first plug-in connection structure 12 and the plug-in structure 121 of the third plug-in connection structure 14 are flush, and the plug-in structure 121 of the second plug-in connection structure 13 and the plug-in structure 121 of the first plug-in connection structure 12 are arranged at intervals in the thickness direction of the board body 11, that is, arranged at intervals in the Z-axis direction. The projection of the plug-in structure 121 of the second plug-in connection structure 13 on the cross section (i.e., XY plane) of the board body 11 is at least partially located outside the area covered by the projection of the plug-in structure 121 of the first plug-in connection structure 12 on the cross section (i.e., XY plane) of the board body 11, for example, along the first direction, the plug-in structure 121 of the second plug-in connection structure 13 and the plug-in structure 121 of the first plug-in connection structure 12 are arranged at intervals.

[0065] The advantage of such a configuration is that more slot structures 122 and more plug-in structures 121 can be arranged in a limited space, thereby improving the space utilization of the adjacent end faces of two adjacent plate bodies 11, and the two adjacent plate bodies 11 have a larger contact area. The two adjacent plate bodies 11 have a strong connection force in the thickness direction and the first direction of the plate body 11, and the connection has high stability and reliability.

[0066] like Figure 2 , Figure 4 , Figures 5 to 7 As shown, in the embodiment of the present invention, adjacent ends of two adjacent slot structures 122 along the first direction are connected as one.

[0067] like Figure 4 As shown, exemplarily, the side wall of the slot structure 122 of the first plug connection structure 12 along the thickness direction of the board body 11 is connected to the side wall of the slot structure 122 of the second plug connection structure 13 along the thickness direction of the board body 11 as a whole.

[0068] At this time, two adjacent plug-in structures 121 are arranged at intervals to form a first accommodation space 17, and the adjacent ends of two adjacent slot structures 122 along the first direction are connected as a whole and inserted into the first accommodation space 17, and the adjacent side walls of the two slot structures 122 along the first direction are deformed and press against the side wall of at least one plug-in structure 121 along the first direction. It can also be said that the deformation directions of the two adjacent plug-in structures 121 along the thickness direction are opposite, and to a certain extent press against the side wall of at least one slot structure 122 along the first direction, thereby realizing the stable plug-in of the two adjacent plug-in connection structures, and the stability and reliability of the connection of the two adjacent board bodies 11 are higher than that of the single plug-in.

[0069] Compared with a single slot structure 122, the adjacent ends of two adjacent slot structures 122 are connected, which has better torsional and shear resistance; and, at this time, every three plug-in structures 121 together form a groove structure suitable for inserting a slot structure 122, and two adjacent plate bodies 11 are formed into a stable connection body through the corresponding insertion of multiple plug-in structures 121 and multiple slot structures 122, which has high stability.

[0070] At this time, the multiple plug-in structures 121 and the multiple slot structures 122 form multiple interlocking boxes through deformation in various directions, and have high rigidity in the width direction of the slot structure 122 and the thickness direction of the board body 11. The slot structure 122 can be understood as the bottom of the box body, and the plug-in structure 121 can be understood as the cover of the box body, but there is no limitation on the specific structure of the box body. For example, the contact surface of the plug-in structure 121 and the slot structure 122 can be a whole surface structure.

[0071] Embodiment 1

[0072] like Fig.14 and Fig.15 As shown, different from the electrical installation board 1 in the above embodiment, the electrical installation board 1 includes a card-connecting limiting structure, and the card-connecting limiting structure includes a card hole structure 43 and a card connector 44; wherein at least one limiting structure 41 is provided with a card hole structure 43, and at least one stop structure 42 corresponding to the limiting structure 41 is provided with a card connector 44, when the plug-in structure 121 is inserted into the corresponding slot structure 122, the card connector 44 is at least partially accommodated in the card hole structure 43 and card-connected with the card hole structure 43 to limit the separation of the plug-in structure 121 and the slot structure 122.

[0073] For example, the card hole structure 43 is opened in the slot structure 122, the card connector 44 is arranged on the plug-in structure 121, and the card connector 44 and / or the slot structure 122 are provided with a guiding inclined surface. In the process of inserting the plug-in structure 121 into the slot structure 122, under the action of the guiding inclined surface, the card connector 44 undergoes elastic deformation until the card connector 44 moves to a position corresponding to the card hole structure 43. Under the action of the elastic force, the card connector 44 is at least partially accommodated in the card hole structure 43 and contacts the side wall of the board body 11 of the card hole structure 43 close to the plug-in structure 121, so as to limit the separation of the slot structure 122 and the plug-in structure 121 along the plug-in direction (i.e., the X-axis direction).

[0074] Of course, the arrangement of the clamping limit structure may also be that at least one limit structure 41 is provided with a clamping member 44, and at least one stop structure 42 corresponding to the limit structure 41 is provided with a clamping hole structure 43, which will not be described in detail here.

[0075] The number of the clamping and limiting structures may be one or more, and they do not serve as a limit. For example, two clamping and limiting structures are respectively located at two ends of the first direction.

[0076] The advantage of such a configuration is that when the plug-in structure 121 is inserted into the corresponding slot structure 122 to realize the connection between the two board bodies 11, the two board bodies 11 are limited to separate by the clamping limit structure, and the overall structural stability of the electrical installation board 1 is high and the practicability is strong.

[0077] Embodiment 2

[0079] Exemplarily, a first hole structure 181 is provided on the slot structure 122, and a second hole structure 182 is provided on the corresponding plug-in structure 121. When the slot structure 122 is located above the corresponding plug-in structure 121 (i.e., located in the positive direction of the Z-axis), the fastener passes through the first hole structure 181 and is threadedly connected to the second hole structure 182. When the slot structure 122 is located below the corresponding plug-in structure 121, the fastener passes through the second hole structure 182 and is threadedly connected to the first hole structure 181. The fastener may be a screw, a bolt, a self-tapping screw, etc.

[0081] The advantage of such a configuration is that after two adjacent board bodies 11 are connected as a whole through a plurality of plug-in connection structures, the fastening is strengthened by fasteners, and the overall structure of the electrical installation board 1 is highly stable and practical.

[0083] like Figure 2 and Figure 4 As shown, different from the electrical installation board 1 in the above embodiment, the electrical installation board 1 also includes a first positioning hole structure 15, wherein the first positioning hole structure 15 is arranged at at least one plug-in structure 4, and along the thickness direction of the board body 11, the first positioning hole structure 15 penetrates at least one of the two adjacent board bodies 11 from top to bottom, and the first positioning hole structure 15 is suitable for being connected to the clamping assembly 3 of the box body 2 to realize the positioning and clamping of the board body 11 in the box body 2.

[0084] Specifically, a clamping assembly 3 is connected to the box body 2, which is pressed against the edge of the first positioning hole structure 15 from top to bottom. When the first positioning hole structure 15 passes through two adjacent plate bodies 11, the clamping assembly 3 can also pass through the first positioning hole structure 15 and be connected to the bottom plate of the box body 2, thereby achieving the clamping and positioning of the electrical installation board 1.

[0085] Embodiment 4

[0086] like Figure 5 As shown, different from the electrical installation board 1 in the above embodiment, a wire slot structure 19 is provided on the board body 11, and the wire slot structures 19 on two adjacent board bodies 11 are connected.

[0087] It should be noted that the specific structure of the wire trough structure 19 is not a limitation. Its specific structure is determined according to the installation arrangement of the electrical appliances on the board body 11, so that part of the power line can extend from the wire trough structure 19 to each electrical appliance, which can improve the safety performance to a certain extent.

[0088] Optionally, a wire trough cover (not shown) may be provided on the wire trough structure 19. The wire trough cover is provided at the opening of the wire trough structure 19 and is snap-fitted to the wire trough structure 19.

At least two plug-in structures 4 are distributed at intervals along the first direction (not shown in the diagram of this scheme).

[0094] like Fig.13 As shown, two plate bodies 11 are connected via two plug-in structures 4 , and each plug-in structure 4 includes three stop structures 42 and three limiting structures 41 .

[0095] Embodiment 7

[0096] Different from the electrical installation board 1 in the above embodiment, Figure 5 , Fig.10 and Fig.11 As shown, a plurality of slot structures 16 are provided on the board body 11 , and the slot structures 16 are suitable for being engaged with the clamping structures 5 provided on the box body 2 .

[0097] For example, along the distribution direction of the board bodies 11, at least the board bodies 11 at both ends of all the board bodies 11 are provided with a slot structure 16. When multiple board bodies 11 are connected as one, the electrical installation board 1 and the box body 2 are integrally connected through the slot structure 16 and the clamp structure 5.

[0098] Specifically, Fig.10 and Fig.11 As shown, the slot structure 16 is provided with an entrance for the clamping structure 5 to extend into, and the clamping structure 5 is adapted to extend into the slot structure 16 through the entrance and move to a position for clamping with the slot structure 16 .

[0099] The clamping structure 5 may be a buckle or hook disposed on the box body 21. The slot structure 16 is located inside the plate body 11, that is, the plate body 11 has a certain thickness, and a cavity is provided inside the plate body 11. The side of the plate body 11 facing away from the box body 21 is recessed toward the cavity to form a recessed structure. The recessed structure is located in the cavity and an entrance is provided to form the slot structure 16, so that the clamping structure 5 can be inserted into the slot structure 16 through the entrance. At the same time, in order to achieve accurate and firm pre-positioning of the box body 21 and the plate body 11, a plurality of slot structures 16 are provided, and the clamping structure 5 and the box body 21 can be connected integrally or detachably.

[0100] In this way, after the board body 11 is placed in the box body 21, the card structure 5 will first enter the cavity of the board body 11, move the board body 11, and a part of the card structure 5 will extend into the card slot structure 16 through the entrance and move to the position where it is engaged with the card slot structure 16, thereby playing a role of pre-positioning and basic fixation.

[0101] Embodiment 8

[0102] Different from the electrical installation board 1 in the above embodiment, the projection of the plug-in structure 121 of the first plug-in connection structure 12 on the cross section of the board body 11 is at least partially located within the range covered by the projection of the plug-in structure 121 of the second plug-in connection structure 13 on the cross section of the board body 11, and the projection of the plug-in structure 121 of the first plug-in connection structure 12 on the cross section of the board body 11 is at least partially located outside the range covered by the projection of the plug-in structure 121 of the second plug-in connection structure 13 on the cross section of the board body 11. In this way, the connection between two adjacent board bodies 11 is more stable.

[0103] Embodiment 9

[0104] Different from the electrical installation board 1 in the above embodiment, Figure 5 , Figure 6 and Figure 7 As shown, the electrical installation board 1 includes three board bodies 11 distributed in sequence, wherein the board body 11 located in the middle is the middle board body, the left board body and the middle board body are connected by multiple plug-in connection structures, and the middle board body and the right board body are connected by multiple plug-in connection structures.

[0105] It should be noted that in the above embodiment, the size of the electrical installation board 1 is determined according to actual needs, thereby determining the size and number of the board body 11. The specific size of the slot structure 122 and the plug-in structure 121 can be determined according to actual needs, and the shapes and sizes of the two slot structures 122 do not have to be exactly the same. The plug-in structure 121 and the corresponding slot structure 122 are inserted to form a box structure, so that the strength and rigidity of the electrical installation board 1 at the plug-in structure 4 are guaranteed, and it can bear the weight of the electrical components on the board body 11 without breaking. Of course, when the weight of the electrical components on the board body 11 is different, the number and size of the slot structure 122 and the plug-in structure 121 can be different, which is determined according to actual needs. When the number of board bodies 11 is greater than or equal to three, the structural strength and rigidity of the middle board body and the two board body connections located on both sides of the middle board body can also meet the use needs.

[0106] like Figure 8 and Fig. 9 As shown, another embodiment of the present invention also provides a multi-meter modular metering box, including the electrical installation board 1 as described above, and also including a box body 2 and a plurality of electric energy meters, the electrical installation board 1 is detachably connected to the box body 2, and the plurality of electric energy meters are detachably connected to the electrical installation board 1 respectively.

[0107] like Figure 1 , Figure 1 Shows a six-position electrical installation panel. Figure 8 A modular metering box with 12 meter positions is shown. Each additional panel body 11 can provide more electricity meter installation positions. On this basis, the box body 2 can also be set as an assembly structure. For example, the box body 2 includes multiple box bodies 21, and the multiple box bodies 21 are spliced ​​into a whole. The box body 2 and the electrical installation board 1 are assembled according to the actual number of meter positions required.

[0108] In this way, the number of plate bodies 11 can be increased according to actual needs to meet the needs of multiple meters without forming higher requirements on the processing size specifications of the electrical installation plate 1. Through the modular assembly of plate bodies 11 with a limited number of specifications and sizes, the multiple meter requirements of the multi-meter modular metering box can be met. The electric energy meter and each electrical appliance are installed on the electrical installation plate 1 to form a metering assembly with each electrical appliance. The metering assembly is easy to be installed as a whole on the box body 2 or disassembled from the box body 2, and is easy to assemble in batches. The modular metering box has a simple structure and strong practicality, which greatly improves the scope of application of the modular metering box. It has broad application prospects and high social and economic value.

[0109] Optionally, at least one of a communication module, a main electric energy meter and a main circuit breaker is installed on a board body 11 of the electrical installation board 1 .

[0110] like Figure 5 and Figure 6 As shown, the left side panel body is provided with installation positions for the communication module, the total electric energy meter and the total circuit breaker, and the middle panel body and the right side panel body are respectively provided with 6 electric energy meter positions to realize the separate installation of the main control and each sub-meter.

[0111] The communication module can be an Internet of Things module, which is used for communications such as 4G or 5G, forming an intelligent multi-meter modular metering box.

[0112] Alternatively, if Figures 8 to 12 As shown, the multi-meter modular metering box also includes a clamping assembly 3, which is located on the side of the opening of the plate body 11 facing the box body 21, and a part of the clamping assembly 3 is suitable for connecting with the box body 21. The clamping assembly 3 includes a connecting piece 31 and a clamping structure 32. The connecting piece 31 is respectively connected to the box body 21 and the clamping structure 32. The clamping structure 32 contacts the edge of the first positioning hole structure 15, and the connecting piece 31 is suitable for limiting the displacement of the plate body 11 relative to the box body 21 through the clamping structure 32.

[0113] like Fig.12 As shown, the multi-meter modular metering box also includes a mounting seat 7 and a fixing member 8. The mounting seat 7 is arranged inside the box body 21. The mounting seat 7 passes through the first positioning hole structure 15, and the size of the first positioning hole structure 15 is larger than the size of the mounting seat 7. The clamping structure 32 is sleeved on the part of the mounting seat 7 passing through the first positioning hole structure 15. The fixing member 8 is suitable for sequentially connecting the connecting member 31, the clamping structure 32 and the mounting seat 7 along the depth direction of the box body 21.

[0114] Optionally, a positioning piece is provided on one side of the bottom of the box body 21 near the opening, and the position of the positioning piece corresponds to the position of the clamping hole structure 43. When the electrical installation board 1 is installed on the box body 21, the positioning piece is inserted into the clamping hole structure 43 along the thickness direction of the board body 11, and contacts the side opposite to the clamping surface of the clamping piece 44. In other words, only when the electrical installation board 1 is separated from the box body 21 and the positioning piece is separated from the clamping piece 44, can the clamping piece 44 be separated from the clamping hole structure 43.

[0115] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention, and the protection scope disclosed by the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
