Description

Technical Field

[0001] The utility model relates to the technical field of power supply voltage stabilization equipment, in particular to a power supply voltage stabilization device. Background Art

[0002] During the assembly and debugging process of some electronic products, due to the time consumption of electronic components, the power supply voltage requirements are higher during the product assembly and debugging process. There are power supply voltage fluctuations and load changes, which lead to large instantaneous power. The voltage drops below the rated voltage value, and the product cannot complete the functional test, thus affecting normal operation.

[0003] Traditional methods for preventing power outages include: 1. Adding a backup power source, such as a battery, can ensure the system continues to operate normally after a power outage, but this requires appropriate charging and discharging circuits, which is costly. 2. Using specialized power-off protection chips, such as the MAX691 and MAX709, can effectively extend the system's operating time after a power outage, but these chips require complex circuitry and are expensive to design. 3. Using capacitors, which leverage their delayed discharge characteristics, can effectively compensate for power outages during power switching and maintain a stable voltage, requiring a simpler circuit. In actual operating circuits, circuit voltages may fluctuate due to various factors, such as power supply voltage fluctuations and load variations. Voltage regulators are primarily used to adjust the input voltage to maintain it within a fixed, appropriate range, ensuring that the voltage in the circuit remains stable. For precision instruments and products with high voltage requirements, stable voltage can improve efficiency and extend their service life. However, traditional voltage regulators are bulky, require a lot of consumable components, and are susceptible to electromagnetic interference. Furthermore, the output power suffers from voltage ripple and surges, resulting in low output quality. Utility Model Content

[0014] In order to make the structural features and usage of this utility model clearer, the following Figure 1 、 2 , 3, 4, 5, 6 and embodiments further illustrate the technical solutions and advantages of the utility model.

[0015] A power supply voltage stabilizing box device comprises a box body, a box cover, and an integrated circuit board. The box body includes ventilation slots 12, a cooling fan 16, and a power input connector 14. The power input connector 14 extends through the box body via terminal blocks 18 and is secured to the box body with nuts 19. The inside of the box body 13 is evenly distributed with threaded mounting holes 15 that match the box cover. Four circuit board mounting posts 20 are provided on the bottom surface of the inner wall of the box body. Screws penetrate the circuit board 17 and are threadedly connected to the circuit board mounting posts 20. The O-type crimping terminal of the power input connector 14 is fixed between the terminal blocks 18 and the nuts 19.

[0016] The box body 13 and the box cover 1 are both made of ABS material with light weight and good insulation. The edges and corners are all rounded. The inner covers of the box body and the box cover are equipped with silicone sealing strips. The internal circuit board mounting posts 20 and the box cover mounting holes 15, the power input connector 14 mounting holes, and the power output connector 4 mounting holes are all processed together with the box body and the box cover to ensure that the device has a high structural strength. The assembly box cover mounting holes 15 are nylon screws, which can effectively prevent falling off. The connector assembly terminals are all copper terminals with good conductivity.

[0017] The surface of the integrated circuit board 17 is welded with a bridge rectifier diode circuit 22, a CLC filter 24, a DC / DC power module 25, a tantalum electrolytic capacitor 23, a resistor 26, and a screw-type distributor terminal 21. The circuit board 17 is electrically connected to the bridge rectifier diode circuit 22, CLC filter 24, DC / DC power module 25, tantalum electrolytic capacitor 23, resistor 26, and screw-type distributor terminal 21. The cooling fan 16 is connected in series with the DC / DC power module 25 via internal wiring, and the resistor 26 is connected in series with the power indicator light 3. The DC / DC power module on the integrated circuit board 17 supplies power to the cooling fan 16, maintaining the operating temperature of the circuit. The CLC filter 24 on the circuit board 17 filters out voltage ripple and surges from the input power supply, protecting electrical equipment from damage. The bridge rectifier diode circuit 22 on the circuit board 17 prevents damage to the circuit due to incorrect connection of the circuit. The bridge rectifier diode circuit 22 prevents the positive and negative polarity of the connector from being incorrectly connected during use, and the number of power output connectors can be adjusted according to actual use.

[0018] The box cover 1 includes a power supply indicator light 3, a power output connector, and a screw 2. The power output connector includes a potentiometer knob 4, a copper core terminal 5, nuts (6, 8, 11), and elastic gaskets (7, 9, 10). The power supply indicator light 3 is connected in series with a resistor 26 through an internal wire. At the same time, the power supply indicator light 3 is connected in series with the positive and negative poles of the power output connector through O-type crimping terminals. The O-type crimping terminals of the power output connector are located between the nut 8, the elastic gasket 8 and the nut 11, the elastic gasket 10.

[0019] The method of using the utility model is as follows Figure 6 As shown:

[0020] (1) After adjusting the current and voltage of the DC regulated power supply to the required value, turn off the power output (to prevent hazards during live operation), and connect the power supply connection line of the DC regulated power supply to the positive input terminal 14 and the negative input terminal 15 of the power stabilizing device through the O-type crimping terminal;

[0021] (2) Connect the power supply cable of the assembled and debugged product to the output end of the power supply voltage regulator (power output connector 4) through the O-type crimping terminal;

[0022] (3) Turn on the power output of the DC regulated power supply. At this time, the DC regulated power supply is filtered and stabilized by the power stabilizing device to supply power to the assembled and debugged product. After the power indicator light 3 lights up, the product debugging operation can be started.

[0023] The working principle of this utility model is as follows Figure 6 As shown:

[0024] This utility model, as a voltage stabilizing device connecting a DC regulated power supply and a product requiring debugging, primarily utilizes the tantalum electrolytic capacitor 23 within the integrated circuit board 17 within the voltage stabilizing device to replenish energy when instantaneous power consumption is high, thereby lowering the voltage output. This ensures the operating voltage of the product requiring debugging, preventing power outages and the inability to complete debugging during product debugging. Through the bridge rectifier diode circuit 22 within the integrated circuit board 17, the output polarity is not affected even if the positive and negative input terminals 14 and 15 of the power supply are connected in reverse. Power is supplied to the cooling fan 16 via the DC / DC power module 25 within the integrated circuit board 17, effectively maintaining the operating temperature of the circuit. Through the CLC filter 24 within the integrated circuit board 17, voltage ripple and surge voltages from the input power supply can be filtered out, ensuring power quality and reducing interference from the power supply to the product. This patent allows for the number of power output connectors to be changed according to the product debugging requirements, demonstrating its versatility.
