The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0030] See also Figure 1The present application provides a driving board 100, which is applied to a distribution box 200 (such as Figure 4 As shown in FIG. 1 ). The driving board 100 includes at least two sub-driving boards 10 of modular design. At least two sub-driving boards 10 are arranged in parallel. Each sub-driving board 10 includes a circuit board 11 and a connector 12. The connector 11 is arranged on the circuit board 12, and two adjacent sub-driving boards 10 are electrically connected through the connector 11.

[0031] Specifically, the connector 12 can be arranged on the circuit board 11 by welding, so that the connector 12 is firmly arranged on the circuit board 11. The connector 12 can be a harness connector 12 or the like. Two adjacent sub-drive boards 10 can be arranged in parallel and electrically connected through the connector 12 to modularize the multiple sub-drive boards 10. It should be noted that the number of the multiple sub-drive boards 10 can be, for example, 2, 3, 4, 5, 6, 7, 8, 9 or 10, which is not limited here.

[0032] In one embodiment, when the load required by the distribution box 200 increases, the user can add sub-driver boards 10 according to the amount of increased load, and electrically connect two adjacent sub-driver boards 10 through the connector 12, so that the number of sub-driver boards 10 matches the load of the distribution box 200, thereby facilitating the subsequent collection of the load current of the distribution box 200.

[0033] In another embodiment, when the load required by the distribution box 200 is reduced, the user can unplug the wiring harnesses connecting the connectors 12 according to the amount of load reduction, and cancel the electrical connection between two adjacent sub-driving boards 10, so that the driving board 100 will not be deformed and damaged due to its long length, and it can also avoid the waste of resources caused by the extra driving boards 100 not being used.

[0034] It should be noted that the load of the distribution box 200 may be a main circuit and a circuit breaker, etc., which is not limited here.

[0035] In this way, the driving board of the present application can electrically connect two adjacent sub-driving boards 10 through the connector 12, so that the driving board can increase or decrease the number of modularly designed sub-driving boards 10 according to the number of loads required by the distribution box 200, thereby ensuring that the driving board 100 will not be deformed and damaged due to its long length. At the same time, the number of sub-driving boards 10 of the driving board 100 can also be freely selected according to user needs, which has high flexibility.

[0036] In some embodiments, the sub-driver board 10 includes a current transformer metering board 13 disposed on the circuit board 11. The current transformer metering board 13 is disposed on the circuit board 11. The current transformer metering board 13 is used to measure and sample the current of the load of the distribution box 200. That is, the current transformer metering board 13 can be firmly disposed on the circuit board 11 by welding. The current transformer metering board 13 can be electrically connected to the load of the distribution box 200. When it is necessary to collect the current of the load of the distribution box 200, the current of the load of the distribution box 200 can be measured and sampled by the current transformer metering board 13.

[0037] Please refer again Figure 1 In some embodiments, the sub-driver board 10 further includes a relay 14 disposed on the circuit board 11. The relay 14 is electrically connected to the current transformer metering board 13 and the load of the distribution box 200, respectively. The relay 14 is used to control the on and off of the current transformer metering board 13 and the distribution box 200. That is, the relay 14 can be firmly disposed on the circuit board 11 by welding. One end of the relay 14 can be electrically connected to the current transformer metering board 13, and the other end of the relay 14 can be electrically connected to the load of the distribution box 200, so as to control the on and off of the current transformer metering board 13 and the distribution box 200 through the relay 14.

[0038] In some embodiments, the sub-driver board 10 further includes a wiring terminal 15 disposed on the circuit board 11. The wiring terminal 15 is electrically connected to the relay 14. The wiring terminal 15 is used to electrically connect the relay 14 to the load of the distribution box 200. That is, the wiring terminal 15 can be firmly disposed on the circuit board 11 by welding. One end of the wiring terminal 15 can be electrically connected to the relay 14, and the other end of the wiring terminal 15 can be electrically connected to the load of the distribution box 200 through a copper busbar, so that the relay 14 is electrically connected to the load of the distribution box 200 through the wiring terminal 15.

[0039] In some embodiments, the number of connectors 12 provided on the circuit board 11 is 1 or 2. That is, in one embodiment, when the number of sub-driving boards 10 of the driving board is 2, the number of connectors 12 provided on each sub-driving board 10 may be 1 (e.g., Figure 2 As shown in FIG. 1 , the two sub-driving boards 10 can be electrically connected through the connector 12 to reduce the production cost. It should be noted that when the number of the sub-driving boards 10 of the driving board is 2, the number of the connectors 12 provided on each sub-driving board 10 can also be 2 (as shown in FIG. 1 ). Figure 3 As shown), when the two sub-driving boards 10 are electrically connected through the connector 12, there is no need to distinguish the directions.

[0040] In another embodiment, when the number of sub-driving boards 10 of the driving board is more than 2, one connector 12 may be provided on the first sub-driving board 10 and the last sub-driving board 10, and two connectors 12 may be provided on the sub-driving board 10 between the first sub-driving board 10 and the last sub-driving board 10, so that two adjacent sub-driving boards 10 are electrically connected through the connector 12, which is convenient for subsequent collection of the current of the load of the distribution box 200. It should be noted that when the number of sub-driving boards 10 is more than 2, for example, it can be 3, 4, 5, 6, 7, 8, 9 or 10, which is not limited here.

[0041] In some embodiments, the relays 14, the current transformer metering boards 13, and the wiring terminals 15 correspond one to one. That is, the number of relays 14, the number of current transformer metering boards 13, and the number of wiring terminals 15 can correspond one to one, that is, one relay 14, one current transformer metering board 13, and one wiring terminal 15 can constitute a sampling component, and one sampling component can be connected to a load of the distribution box 200, so that each load of the distribution box 200 has a sampling component dedicated to collecting its current, so that the user can freely control the sampling component connected to the load of the corresponding distribution box 200 to collect the current of the load according to the needs.

[0042] See also Figure 1 In some embodiments, in the corresponding relay 14, the current transformer metering board 13 and the terminal 15, the relay 14 is arranged between the current transformer metering board 13 and the terminal 15. That is, in the corresponding relay 14, the current transformer metering board 13 and the terminal 15, the present application arranges the relay 14, the current transformer metering board 13 and the terminal 15 vertically on the circuit board 11 by arranging the relay 14 between the current transformer metering board 13 and the terminal 15, so as to facilitate the wiring of the terminal 15.

[0043] In some embodiments, the number of relays 14, current transformer metering boards 13 and wiring terminals 15 of each sub-drive board 10 is 1 to 3. That is, the number of relays 14, current transformer metering boards 13 and wiring terminals 15 provided on each sub-drive board 10 can be 1, 2 or 3, and the user can flexibly select a sub-drive board 10 provided with 1, 2 or 3 relays 14, current transformer metering boards 13 and wiring terminals 15 according to the number of loads of the distribution box 200. For example, when the number of relays 14, current transformer metering boards 13 and wiring terminals 15 provided on the sub-drive board 10 is 2, and the number of loads of the distribution box 200 is 10, then 5 sub-drive boards 10 can be electrically connected through the connector 12, and the wiring terminals 15 are electrically connected to the loads of the distribution box 200 one by one, so as to collect the current of the loads of the distribution box 200 through the current transformer metering board 13, and at the same time, it can also ensure that the drive board 100 will not be deformed and damaged due to its long length.

[0044] In some embodiments, the driving board 100 includes a wiring harness (not shown in the figure). The two ends of the wiring harness are respectively connected to the connectors 12 on the two adjacent sub-driving boards 10, so that the two adjacent sub-driving boards 10 are electrically connected. That is, the connectors 12 on the two adjacent sub-driving boards 10 can be connected through the wiring harness, so that the subsequent user can increase or decrease the number of sub-driving boards 10 according to the number of loads required by the distribution box 200, ensuring that the driving board 100 will not be deformed and damaged due to its long length, and the number of sub-driving boards 10 of the driving board 100 can be freely selected according to user needs, which is more flexible.

[0045] See also Figure 4 The present application also provides a distribution box 200. The distribution box 200 includes the driving board 100 described above.

[0046] In this way, the distribution box 200 of the present application can electrically connect two adjacent sub-drive boards 10 through the connector 12, so that the drive board can increase or decrease the number of modularly designed sub-drive boards 10 according to the number of loads required by the distribution box 200, thereby ensuring that the drive board 100 will not be deformed and damaged due to its long length. At the same time, the number of sub-drive boards 10 of the drive board 100 can also be freely selected according to user needs, which has high flexibility.

[0047] In some embodiments, the distribution box 200 includes a box body 210. The drive board 100 is mounted on the inner wall surface of the box body 210. That is, the drive board 100 can be mounted on the inner wall surface of the box body 210 by screwing or snapping, so as to facilitate the installation and removal of the drive board 100. It should be noted that the box body 210 can be made of metal or plastic. When the box body 210 is made of metal, for example, it can be made of aluminum alloy, so as to extend the service life of the box body 210 while reducing the weight of the distribution box 200. When the box body 210 is made of plastic, the production cost can be reduced.

[0048] See also Figure 4 In some embodiments, each sub-driving board 10 is formed with a mounting hole 16, and the sub-driving board 10 is fixed to the inner wall surface of the box body 210 by fasteners.

[0049] Specifically, one or more mounting holes 16 may be formed on each sub-driving board 10, and each sub-driving board 10 may be firmly fixed on the inner wall surface of the box body 210 by inserting fasteners through the mounting holes 16 and the inner wall surface of the box body. It should be noted that when there are multiple mounting holes 16 formed on each sub-driving board 10, for example, there may be 2, 3, 4 or 5, etc., which are not limited here. The fasteners may be, for example, screws, etc.

[0050] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
