[0022] DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0025] The present application provides an electrical device, including a power distributor 1000 and other functional devices, wherein the multiple functional devices are electrically connected to the power distributor 1000 respectively, so that the power distributor 1000 can provide electrical energy to other different devices.

[0026] For the aforementioned distributor 1000, see Figures 1 to 3The power distributor 1000 includes a circuit board 100, a fuse module 200 and an output module 300. The circuit board 100 includes a body 110 and a metal connector (not shown in the figure), and the metal connector is embedded in the body 110. The fuse module 200 includes a first copper column 210 and a fuse 220, the first copper column 210 is mounted on the body 110, the fuse 220 is mounted on the first copper column 210, and the fuse 220 is provided with a fixing portion 221, and the fixing portion 221 fixes the fuse 220 to the first copper column 210, and the fuse 220 is electrically connected to the circuit board 100 through the first copper column 210. The output module 300 is electrically connected to the metal connector, and the other end of the metal connector is electrically connected to the first copper column 210. It is understandable that the present application also includes an input module 600, which is electrically connected to the circuit board 100, so that the electric energy is transmitted to the circuit board 100 through the input module 600, and then passes through the first copper column 210 and the safety piece 220, and then is transmitted to the output module 300 through the metal connector. Specifically, the metal connector includes a copper sheet, which is convenient for embedding the metal connector in the circuit board 100, and has strong conductivity. It should be noted that the metal connector is embedded in the body 110 to reduce exposed cables. At the same time, the copper column is electrically connected to the safety piece 220, which reduces the cables connected to the safety piece 220 while ensuring the safety of the distributor 1000. Compared with the electrical connection form of the copper busbar, the copper busbar requires sufficient space to meet the safety specifications for the use of the copper busbar, and it is not easy to reduce the overall space. That is, through the above structure, the insurance piece 220 is fixed to the circuit board 100 through the first copper column 210, and the electrical connection is achieved, thereby replacing the setting of the cable, and the metal connector embedded in the circuit board 100 can output the current to the output module 300. When maintenance is needed, it only needs to be directly replaced.

[0027] For further information, see Figure 2, and combined with other drawings. The number of the first copper pillars 210 is at least two, and the safety member 220 includes: a mounting bracket 222 and a fuse 223, a fixing portion 221 is bent and arranged at the two ends of the mounting bracket 222, and the two fixing portions 221 are mounted on the first copper pillar 210, and the fuse 223 is mounted on the mounting bracket 222; or, the mounting bracket 222 and the fuse 223 are integrally formed, and the two ends of the mounting bracket 222 are mounted on the first copper pillar 210. That is, the mounting bracket 222 and the fuse 223 can be integrally formed or separately set, and the integrally formed mounting bracket 222 and the fuse 223 are easy to produce, while the separately set mounting bracket 222 and the fuse 223 are easy to repair and replace. It is necessary to explain that the number of the first copper pillars 210 in the embodiment of the present application is three. It is understandable that the first copper column 210 is installed on the body 110, and the first copper column 210 is protruding relative to the body 110, so as to prevent the fuse 223 or the mounting bracket 222 from directly contacting the body 110. Compared with the arrangement of cables, the first copper column 210 has a simple structure and is easy to check, which prevents the distributor 1000 from having too many cables and complicated circuits; on the other hand, the first copper column 210 is installed on the body 110, and compared with the arrangement of copper bars, the first copper column 210 does not need to occupy too much space, thereby reducing the occupied space and improving the space utilization.

[0028] For further information, see Figure 3 , and in combination with other drawings. The mounting bracket 222 is concavely arranged toward the direction of the circuit board 100. The fuse 223 is cylindrical, and the inner contour of the mounting bracket 222 fits the outer contour of the fuse 223. It can be understood that the mounting bracket 222 is arranged in a semi-arc surface, so as to facilitate fixing the fuse 223 and prevent the fuse 223 from sliding out.

[0029] For further information, see Figure 2 , and in combination with other drawings. The fixing portion 221 includes a first fixing portion 2211 and a second fixing portion 2212. The first fixing portion 2211 is welded to the first copper column 210, and the second fixing portion 2212 is welded to another first copper column 210; or, the insurance module 200 also includes a locking member 400, one locking member 400 passes through the first fixing portion 2211 and is screwed to a first copper column 210, and the other locking member 400 passes through the second fixing portion 2212 and is screwed to another first copper column 210. It can be understood that the locking member 400 includes a bolt, a stud, etc. Through the above structure, since the positions of the fixing portion 221, the first copper column 210, the body 110, and the insurance member 220 are fixed, it is convenient for automatic installation on the production line, no manual wiring is required, and production efficiency is improved.

[0030] In the embodiments of this application, please refer to Figure 2, and combined with other drawings. The power distributor 1000 also includes an input module 600, and the input module 600 includes an input connector 610 and an input fixing member 620. The input fixing member 620 fixes part of the input connector 610 to the circuit board 100, and the input connector 610 is electrically connected to the circuit board 100. Specifically, the input connector 610 is clamped between the input fixing member 620 and the circuit board 100, and a gap is left between the input connector 610 and the circuit board 100, which has reached the safety standard. The input fixing member 620 is set as a bolt, or a welding foot. The input connector 610 is bent, and the circuit board 100 is concavely provided with a first avoidance portion 130, and another part of the input connector 610 extends into the first avoidance portion 130, and the first avoidance portion 130 is used to avoid the input connector 610. Thereby reducing the space occupied by the input connector 610 and improving the space utilization rate. It can be understood that the end of the input connector 610 extending into the first avoidance portion 130 is arranged in a hollow cylindrical shape, and the cylindrical wall of the input connector 610 is provided with a gap, so that when the external connector is electrically connected to the input connector 610, the connection stability can be enhanced by compressing the gap, and the interference with the electrical connection between the external connector and the input connector 610 when there is a tolerance in the external connector can be reduced.

[0031] In the embodiments of this application, please refer to Figure 2 , and in combination with other drawings. The circuit board 100 is further provided with a second avoidance portion 140 which is arranged away from the first avoidance portion 130. When viewed along the extending direction of the circuit board 100, the projection of the output module 300 partially overlaps with the second avoidance portion 140. The second avoidance portion 140 is used to avoid part of the output module 300. This saves internal space and improves space utilization.

[0032] In the embodiments of this application, please refer to Figure 2 , and in combination with other drawings. In a direction perpendicular to the body 110, the mounting bracket 222 is higher than the first fixing portion 2211 and the second fixing portion 2212. Thus, the fuse 223 does not directly contact the copper column or the first fixing portion 2211 or the second fixing portion 2212, thereby improving the safety performance of the circuit.

[0033] For further information, see Figure 2 , and in combination with other drawings. The two ends of the fuse 223 are respectively protruded relative to the two ends of the mounting bracket 222; along the direction perpendicular to the body 110, the first fixing portion 2211 avoids the fuse 223, and the second fixing portion 2212 avoids the fuse 223. Thus, while ensuring the specifications of the fuse 223, its installation position is safe to prevent short circuit.

[0034] In the embodiments of this application, please refer to Figure 2, and in combination with other drawings. There are multiple fuses 220, and multiple fuses 220 are arranged in parallel, and one fuse 220 is electrically connected to one metal connector. It can be understood that the parallel arrangement means that each fuse 223 is arranged in parallel along the same direction, so as to facilitate the circuit planning of the metal connector. Specifically, there are three fuses 220, and the number of circuits in the metal connector is also at least three, so as to facilitate the electrical connection of the fuses 220 one by one.

[0035] In the embodiments of this application, please refer to Figure 1 , and in combination with other drawings. The power distributor 1000 also includes a housing 500, which is provided with a receiving cavity 510 and an output port 520. The circuit board 100 and the fuse module 200 are received in the receiving cavity 510, and the output module 300 is installed at the output port 520 and at least partially extends into the receiving cavity 510. It can be understood that the output port 520 connects the receiving cavity 510 and the external environment, so as to facilitate the output of electric energy through the output port 520. Correspondingly, a protective housing 500 is also provided at the output port 520 to protect the output module 300. Impurities such as dust and liquid in the external environment are reduced from adhering to the surface of the output module 300 to prevent the output module 300 from short-circuiting.

[0036] For further information, see Figure 2 , and in combination with other drawings. The circuit board 100 includes a second copper column 120, and a metal connector is electrically connected to the second copper column 120. The output module 300 includes a plurality of metal connecting pieces 310, one end of the metal connecting piece 310 extends from the output port 520, and the other end extends into the receiving cavity 510, and a metal connecting piece 310 is fixed and electrically connected to a second copper column 120. It can be understood that the metal connector is electrically connected to the second copper column 120 from the inside of the body 110, and the circuit is connected by fixing the metal connecting piece 310 to the second copper column 120. The second copper column 120 and the metal connecting piece 310 can also be fixed by welding or screwing. It is worth mentioning that the metal connector divides the circuit into positive and negative poles at the second copper column 120 and is electrically connected to the metal connecting piece 310, so that the output module 300 can output electrical energy. Through the above structure, the cable setting during the output of the distributor 1000 is reduced, the circuit is simplified, wiring errors and positioning errors of the output module 300 during installation are prevented, and maintenance and replacement are facilitated.

[0037] For further information, see Figure 2, and in combination with other drawings. A portion of the metal connecting sheet 310 is electrically connected to the circuit board 100. The circuit board 100 also includes a power distribution connector 150, which is bent in a direction away from the body 110, one end of the power distribution connector 150 is connected to the circuit board 100, and the other end is connected to another portion of the metal connecting sheet 310, and the other portion of the metal connecting sheet 310 is electrically connected to the circuit board 100 through the power distribution connector 150. It can be understood that the portion of the metal connecting sheet 310 and the other portion of the metal connecting sheet 310 correspond to the positive and negative poles of the circuit divided by the above-mentioned metal connector at the second copper column 120.
