[0038] Please combine Figures 1 to 3The application provides a selected load metering board 100 for a smart distribution box 1000. The selected load metering board 100 comprises a main board 10, a selected main circuit 30 and a connecting piece 40. The main board 10 is provided with a plurality of selected controllable load circuits 20. The selected main circuit 30 is electrically connected with the selected controllable load circuits 20.

The connecting piece 40 is used to connect with a fixed load metering board 200 of the smart distribution box 1000 to expand the number of controllable load circuits of the smart distribution box 1000.

[0039] Specifically, the plurality of selected controllable load circuits 20 can be arranged on the main board 10 by screwing or welding and respectively located on both sides of the selected main circuit 30 to be electrically connected with the selected main circuit 30, so that the connecting piece 40 and the selected controllable load circuits 20 are firmly arranged on the main board 10.

It should be noted that the plurality of selected controllable load circuits 20 can be 4, 6, 8 or 10, etc., which is not limited herein.

[0040] In an embodiment, if the number of fixed controllable load circuits 230 of the fixed load metering board 200 pre-installed in the smart distribution box 1000 is 8, and the user needs 14 controllable load circuits in actual application, the user can install the selected load metering board 100 with 6 selected controllable load circuits 20 in the smart distribution box 1000 and electrically connect the selected load metering board 100 with the fixed load metering board 200 through the connecting piece 40, so that the number of controllable load circuits in the smart distribution box 1000 is expanded from 8 to 14 to meet the user's demand for the number of controllable load circuits of the smart distribution box 1000.

[0041] Therefore, the selected load metering board 100 of the embodiment of the application can expand the selected load metering board 100 comprising a plurality of selected controllable load circuits 20 on the basis of the fixed load metering board 200 pre-installed in the smart distribution box 1000 by connecting the signal terminal of the selected load metering board 100 with the fixed load metering board 200 of the smart distribution box 1000, so that the user can increase the number of controllable load circuits according to the actual application situation to supply power to more loads, and meet the different demands of the user for the number of controllable load circuits of the smart distribution box 1000.

The signal terminal 411 can be flexibly adjusted in position to be connected to the fixed signal port 220 according to actual installation needs, so that after the signal connecting member 41 is connected to the fixed signal port 220, the energy management module of the smart distribution box 1000 can be communicatively connected with multiple optional controllable load circuits 20, and the on-site installation is convenient without too many complex operations.

[0044] Please refer to Figure 1 and Figure 2 , in some embodiments, the connecting member 40 comprises an optional main circuit conductive member 43. The optional main circuit conductive member 43 is arranged on the optional main circuit 30. After the optional main circuit conductive member 43 is connected to the fixed main circuit conductive member 211 of the fixed load metering board 200 arranged on the fixed main circuit 210, the optional main circuit 30 and the fixed main circuit 210 are conductive.

[0045] Specifically, the optional main circuit conductive member 43 can be arranged on the optional main circuit 30 by integral molding to reduce production cost. It should be noted that the optional main circuit 30 and the fixed main circuit 210 can both be copper bars.

The fixed signal port 220 can be adapted to the signal connector 41, so that the optional load metering board 100 can be communicatively connected to the fixed load metering board 200. It should be noted that the plurality of fixed controllable load circuits 230 can be 4, 6, 8 or 10, etc., which is not limited herein.

[0057] The energy management module 300 can be arranged in the smart distribution box 1000 by clamping or screwing and located at one end of the fixed load metering board 200, so as to electrically connect the energy management module 300 to the fixed load metering board 200, so that the energy management module 300 can be used to control the plurality of fixed controllable load circuits 230, and used to control the plurality of optional controllable load circuits 20 after the fixed main circuit conductor 211 and the optional main circuit conductor 43 are connected, and the signal connector 41 and the fixed signal port 220 are connected.

After the energy management module 300, the fixed load metering board 200 and the optional load metering board 100 are sequentially installed in the accommodation space 400, the inner door plate 500 and the movable door plate 600 can be sequentially covered on the accommodation space 400 in a clamping or screwing manner and cover the energy management module 300, the fixed load metering board 200 and the optional load metering board 100 installed in the accommodation space 400, so that the accommodation space 400 is in a relatively closed space, which protects the energy management module 300, the fixed load metering board 200 and the optional load metering board 100, and prevents external dust and other pollutants from polluting the energy management module 300, the fixed load metering board 200 and the optional load metering board 100. It should be noted that the inner door plate 500 and the movable door plate 600 can be made of plastic or metal. That is, when the inner door plate 500 and the movable door plate 600 are made of plastic, the production cost can be reduced. When the inner door plate 500 and the movable door plate 600 are made of metal, for example, can be made of aluminum alloy, so as to prolong the service life of the inner door plate 500 and the movable door plate 600, and reduce the weight of the inner door plate 500 and the movable door plate 600.

[0066] As shown in Figure 7 and Figure 9 The inner door plate 500 is provided with a first hole site 510 and a second hole site 530 spaced apart from the first hole site 510 by a predetermined distance. The fixed load metering board 200 further includes a first circuit breaker 101. The first circuit breaker 101 can be connected with one end of the third conductive sheet 241 passing through the fixed mutual inductor 260. The first circuit breaker 101 can be exposed from the inner door plate 500 through the first hole site 510, so that the inner door plate 500 can shield the fixed load metering board 200, and facilitate the user to control the shutdown of the first circuit breaker 101. The optional load metering board 100 can include a second circuit breaker 280, and the second circuit breaker 280 can be connected with one end of the second conductive sheet 73 passing through the mutual inductor 90 and extending from the circuit breaker mounting groove 631 of the cover plate 63 (as shown in Figure 10The second circuit breaker 280 can be exposed from the inner door plate 500 through the second hole site 530 when the optional load metering plate 100 is installed in the accommodation space 400, so that the inner door plate 500 can play a role in shielding the optional load metering plate 100, and the user can conveniently control the switching off of the second circuit breaker 280. It should be noted that, as shown in Figure 10 and Figure 11 The circuit breaker mounting groove 631 of the cover plate 63 can be arranged at a position corresponding to the mutual inductor 90, so that the second conductive sheet 73 can directly extend from the circuit breaker mounting groove 631 after passing through the mutual inductor 90 to connect the second circuit breaker 280, and also play a role in limiting the second circuit breaker 280.

[0067] Further, the first hole site 510 and the second hole site 530 can refer to the positions where the knock-out holes are arranged, that is, when the first circuit breaker 101 is not arranged through the first hole site 510 or the second circuit breaker 280 is not arranged through the second hole site 530 to be exposed from the inner door plate 500, the baffle plates on the first hole site 510 and the second hole site 530 can be in a closed state, and the user can decide to knock down the baffle plates on several first hole sites 510 or second hole sites 530 to form several knock-out holes according to the actual required controllable load paths. For example, when the user does not need to select and install the second load metering plate, when installing the intelligent distribution box 1000, only the baffle plate on the first hole site 510 corresponding to the fixed load metering plate 200 can be knocked down to form the knock-out hole corresponding to the first circuit breaker 101, and the baffle plate on the second hole site 530 corresponding to the optional load metering plate 100 can be selected to be reserved, so as to ensure that the unused optional load metering plate 100 is not polluted by dust and pollutants, and is more beautiful. It should be noted that each first hole site 510 can correspond to one or more first circuit breakers 101, and each second hole site 530 can correspond to one or more second circuit breakers 280, which is not limited herein.

[0068] In some embodiments, the fixed load metering plate 200 further comprises a fixed cover plate 270, which is arranged on the fixed load metering plate 200 and detachably installed in the accommodating space 400. That is, after the fixed load metering plate 200 is installed in the accommodating space 400, the fixed cover plate 270 can be arranged on the fixed load metering plate 200 and detachably fixed in the accommodating space 400 in a buckling manner, so as to facilitate the installation and removal of the fixed cover plate 270, and meanwhile, the fixed cover plate 270 can effectively shield the fixed load metering plate 200 and prevent dust and other pollutants from polluting the fixed load metering plate 200. It should be noted that the fixed cover plate 270 can be made of plastic or metal. That is, when the fixed cover plate 270 is made of plastic, the production cost can be reduced. When the fixed cover plate 270 is made of metal, for example, it can be made of aluminum alloy, so as to prolong the service life of the fixed cover plate 270 and reduce the weight of the fixed cover plate 270.
