[0026] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. Detailed implementation manners
[0027] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0028] Considering that when the current on the PCB board is relatively large, it is very difficult for the structure of the separate PCB board plugging the Hall sensor to achieve large-current sampling. Therefore, the present utility model proposes a solution.
[0029] Specifically, please refer to Figures 2 to 4 , a preferred embodiment of the internal Hall sensor layout structure of the power supply of the present utility model includes: a square PCB board 20, a Hall sensor 21, a first conductive copper column 22, a second conductive copper column 23, and a lap copper bar 24. The Hall sensor 21, the first conductive copper column 22, and the second conductive copper column 23 are welded to the PCB board 20. The Hall sensor 21 is a hollow structure. The first conductive copper column 22 is located inside the hollow structure of the Hall sensor 21. The second conductive copper column 23 is welded to the PCB board 20 near the outside of the Hall sensor 21. The lap copper bar 24 is lapped on the tops of the first conductive copper column 22 and the second conductive copper column 23.
[0030] Wherein, the Hall sensor 21 is welded to the PCB board 20 through pins.
[0031] In this embodiment, the lap copper bar 24 is fixed to the tops of the first conductive copper column 22 and the second conductive copper column 23 by screws 25.
[0032] In this embodiment, a signal connection terminal 26 is welded to the outside of the PCB board 20 near the Hall sensor 21. The PCB board 20 is connected to the control unit through the signal connection terminal 26.
[0033] In this embodiment, the PCB board 20 is connected to the control unit through a cable.
[0034] The structure and the working principle of current sampling of the internal Hall sensor layout structure of the power supply of the present utility model will be elaborated in detail below.
[0035] In this utility model, current is transmitted through the PCB board 20. The Hall sensor 21 with a hollow structure is welded to the PCB board 20 through its own pins for the purpose of fixation. The first conductive copper column 22 and the second conductive copper column 23 are welded to the PCB board 20. Current flows to the first conductive copper column 22 through the traces of the PCB board 20, and the first conductive copper column 22 is welded at the hollow position of the Hall sensor 21. The first conductive copper column 22 is lapped with the second conductive copper column 23 through the lapping copper bar 24, and the lapping copper column is fixed to the tops of the first conductive copper column 22 and the second conductive copper column 23 by screws 25. Current returns to the PCB board 20 after passing through the second conductive copper column 23. What the Hall sensor 21 samples requires current to pass through its center. The layout structure of the Hall sensor 21 inside the power supply of this utility model enables the current of the PCB board 20 to pass through the Hall sensor 21 through the first conductive copper column 22 for the purpose of sampling. The sampling signal of the Hall sensor 21 is conducted to the PCB board 20 through the signal pins on the Hall sensor 21, and is conducted to the signal connection terminal 26 through the traces of the PCB board 20, and is led out to the required control unit through the docking cable. It should be noted that this utility model may not require the signal connection terminal 26, but directly reach the control unit on the PCB board 20 through the self-traces of the PCB board 20.
[0036] The beneficial effects of the layout structure of the Hall sensor inside the power supply of this utility model are:
[0037] Through the above technical solutions, this utility model includes: a square PCB board, a Hall sensor, a first conductive copper column, a second conductive copper column and a lapping copper bar. The Hall sensor, the first conductive copper column and the second conductive copper column are welded to the PCB board. The Hall sensor has a hollow structure. The first conductive copper column is located inside the hollow structure of the Hall sensor. The second conductive copper column is welded to the PCB board near the outside of the Hall sensor. The lapping copper bar laps on the tops of the first conductive copper column and the second conductive copper column, solving the problem of current sampling of the Hall sensor when the current on the PCB board is very large, and the structure is simple and compact.
