Above the installation backplane 1 and within the inner circle of the limit frame 2, there are respectively provided an independent module area one 3, an independent module area two 4, an independent module area three 5, an independent module area four 6, and a main control area 7.

The installation ends of the independent module area one 3, the independent module area two 4, the independent module area three 5, the independent module area four 6, and the main control area 7 are fixedly connected to the upper part of the installation backplane 1. The outer peripheries of the independent module area one 3, the independent module area two 4, the independent module area three 5, the independent module area four 6, and the main control area 7 are respectively in mutual fit with the inner wall of the installation cavity of the limit frame 2. The setting of the limit frame 2 can fix and limit the independent module area one 3, the independent module area two 4, the independent module area three 5, the independent module area four 6, and the main control area 7 after installation, so that the independent module area one 3, the independent module area two 4, the independent module area three 5, the independent module area four 6, and the main control area 7 are more stable during the installation operation state. Independent single pins 11 and independent double pins 12 are respectively provided on both sides of the independent module area one 3, the independent module area two 4, the independent module area three 5, and the independent module area four 6. The independent single pins 11 and the independent double pins 12 are respectively correspondingly installed with the connection sides of the independent module area one 3, the independent module area two 4, the independent module area three 5, and the independent module area four 6. The independent single pins 11 and the independent double pins 12 are respectively fixedly connected to both sides of the corresponding independent module area one 3, the independent module area two 4, the independent module area three 5, and the independent module area four 6. Main control double pins 13 and main control single pins 14 are respectively provided on both sides of the main control area 7.

The independent single pins 11 are respectively correspondingly installed with the independent double pins 12 and the main control double pins 13. The independent single pins 11 are respectively slidably connected to the independent double pins 12 and the main control double pins 13. When the independent single pins 11 are in close contact with the independent double pins 12 or the main control double pins 13, they are in a conducting state. The independent double pins 12 are correspondingly installed with the main control single pins 14. The independent double pins 12 are slidably connected to the main control single pins 14. When the independent double pins 12 are in close contact with the main control single pins 14, they are in a conducting state.Signal through holes 15 are provided in the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7. A protective housing 8 is provided above the mounting backplane 1. The lower part of the protective housing 8 is correspondingly installed with the upper part of the mounting backplane 1, and the lower part of the protective housing 8 is fixedly connected to the upper part of the mounting backplane 1. The protective housing 8 is set to be concave. The lower inner side of the protective housing 8 is mutually attached to the outer periphery of the limiting frame 2. The setting of the protective housing 8 can protect the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 above the mounting backplane 1, thus avoiding the situation that the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 are damaged due to external damage. There are gaps on the mutually adjacent sides of the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7. The setting of the gaps between the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 can better dissipate heat when each component works for a long time, avoiding the situation of uneven heat dissipation caused by thermal contact. There are gaps between the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 and the inner wall of the protective housing 8. The setting of the gaps formed between the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 and the protective housing 8 can enable the protective housing 8 to protect the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 while avoiding interfering with the heat dissipation of the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7, so that the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 can work better. A positioning frame 20 is provided on the inner side of the protective housing 8. One side of the positioning frame 20 is fixedly connected to the protective housing 8. Multiple groups of area grooves 21 are provided on the positioning frame 20. One side of the positioning frame 20 is correspondingly installed with the inner side of the protective housing 8. The inner walls of the area grooves 21 are mutually attached to the upper outer peripheries of the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7. The setting of the area grooves 21 can further strengthen the stability of the installation state of the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7, and limit and fix the installation ends and tops of the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 by cooperating with the limiting frame 2.Thus, the independent module area 1-3, independent module area 2-4, independent module area 3-5, independent module area 4-6 and the main control area 7 can work better. The mutual cooperation setting of the limit frame 2, positioning frame 20, independent single pin 11, independent double pin 12, main control double pin 13 and main control single pin 14 enables the independent module area 1-3, independent module area 2-4, independent module area 3-5, independent module area 4-6 and the main control area 7 to be used separately or in cooperation according to the operation requirements. Thus, the operator can select and assemble the independent module area 1-3, independent module area 2-4, independent module area 3-5, independent module area 4-6 and the main control area 7 according to the operation conditions. At the same time, according to the settings of the independent module area 1-3, independent module area 2-4, independent module area 3-5, independent module area 4-6 and the main control area 7, the internal assembly of this device can be miniaturized, avoiding waste of resources. The independent module area 1-3, independent module area 2-4, independent module area 3-5 and independent module area 4-6 can all be used in cooperation with the main control area 7 separately, and at the same time, the main control area 7 can be used alone. There are multiple groups of electrically connected bumps 9 arranged above the protective housing 8. The installation ends of each group of electrically connected bumps 9 are correspondingly installed with the upper part of the protective housing 8. The electrically connected bumps 9 are fixedly connected to the protective housing 8. Each group of electrically connected bumps 9 is provided with a signal through-hole identifier 19. The setting of the signal through-hole identifier 19 can enable the operator to more intuitively view the conditions of each port, facilitating use. A connection hole 17 is opened on the electrically connected bump 9. The connection hole 17 corresponds to the position of the signal through-hole 15. The settings of the connection hole 17 and the signal through-hole 15 can enable the plug to be connected and conduct electricity with the independent module area 1-3, independent module area 2-4, independent module area 3-5, independent module area 4-6 or the main control area 7. Each group of electrically connected bumps 9 is provided with an insulating plate 10. One side of the insulating plate 10 is correspondingly installed with the upper part of the electrically connected bump 9. The insulating plate 10 is fixedly connected to the electrically connected bump 9. A positioning hole 18 is opened on the insulating plate 10. The positioning hole 18 corresponds to the position of the connection hole 17. The setting of the positioning hole 18 can limit the plug itself when the plug is inserted into the connection hole 17 and the signal through-hole 15, so that the plug is placed more stably after being inserted. The overall structure of this device is simple and widely applicable. The independent module area 1-3, independent module area 2-4, independent module area 3-5, independent module area 4-6 and the main control area 7 can be selected and assembled according to the operation requirements, thus reducing energy consumption and avoiding overabundant waste of resources. At the same time, through the settings of the limit frame 2 and the positioning frame 20, the frame structure is divided into regions and modular structure design, which can reduce the overall volume of this device. At the same time, it can protect and dissipate heat for the independent module area 1-3, independent module area 2-4, independent module area 3-5, independent module area 4-6 and the main control area 7, enabling more stable operation, realizing the miniaturization and modularization requirements of the rectifier bridge, reducing processes, reducing time consumption, improving efficiency, and reducing production costs.

[0021] In this embodiment, the operator first installs the installation ends of the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 corresponding to the upper part of the inner cavity installation backplane 1 of the limit frame 2 according to the requirements of the operation. Then, the operator assembles the protective shell 8 with the installation backplane 1. At this time, the positioning frame 20 limits and stabilizes the upper parts of the independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7. At the same time, the positions of the signal through holes 15, connection holes 17, and positioning holes 18 correspond to each other, thus completing the assembly operation of the device;

[0022] The independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 can be connected and conducted according to the requirements of the power size according to the settings of the independent single pin 11, independent double pin 12, main control double pin 13, and main control single pin 14. The independent module area 1, independent module area 2, independent module area 3, independent module area 4, and the main control area 7 are modularly arranged. The independent module area 1, independent module area 2, independent module area 3, and independent module area 4 can all be used in cooperation with the main control area 7 alone, and at the same time, the main control area 7 can be used alone.

[0023] The above specific embodiment is only a preferred embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
