Description

Technical Field

[0001] The utility model relates to the technical field of power supply lines for audio equipment, in particular to a power line capable of supplying power and providing closed-loop feedback for instant voltage leveling. Background Art

[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point-to-point. Power cords can be divided into AC power cords and DC power cords according to their uses. They are important power supply components used in various electrical equipment and are widely used.

[0003] The existing power cords have the following disadvantages during use: The advantage of common household appliance output power cords is that the production cost is low and their functions can meet the needs of general household appliances. However, for high-demand music information stream processing and playback devices, voltage fluctuations will cause music distortion and differences from the original sound, which is unacceptable for music information stream processing and playback devices. For this reason, we propose a power cord with power supply and closed-loop feedback to instantly level the voltage. Utility Model Content

[0004] The main purpose of the utility model is to provide a power cord with power supply and closed-loop feedback for instant voltage leveling. The power cord can be designed to feedback the voltage fluctuations generated by the power consumption of the electrical equipment through a loop to a special transformer device, and the voltage output can be adjusted instantly according to the voltage fluctuations generated by the power consumption of the electrical equipment, thereby achieving stable voltage output, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A power cord for power supply and closed-loop feedback for instant voltage leveling comprises a mains AC-DC transformer, a two-core power supply line and a two-core feedback line are plugged into the power supply end of the mains AC-DC transformer, a DC adapter board is provided at the connection between the ends of the two-core power supply line and the two-core feedback line, and a DC connector is installed at the power supply end of the DC adapter board.

[0007] Furthermore, the DC adapter board has a built-in voltage detection sensor component; through the built-in voltage detection sensor component in the DC adapter board, the instantaneous voltage value of the electrical equipment when using electricity is monitored in real time.

[0008] Furthermore, a connecting wire is installed between the power supply end of the DC adapter board and the DC connector; the connecting wire serves to connect the power supply between the DC adapter board and the DC connector.

[0009] Furthermore, the connection ends of the two-core power supply lines and the two-core feedback lines are both equipped with power supply connectors and are electrically connected to the AC / DC transformer via the power supply connectors; the two-core power supply lines and the two-core feedback lines are both connected to the AC / DC transformer via the power supply connectors.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the power supply end of the AC-DC transformer is connected to the mains, which can convert the mains into direct current and output it, and at the same time, it can internally receive data feedback from voltage monitoring and adjust the output voltage, the DC connector is connected to the power-consuming end of the speaker device, and a two-core power supply line and a two-core feedback line are used to connect the DC adapter board and the AC-DC transformer of the mains. The real-time voltage value during power consumption is collected through the built-in voltage sensor component of the DC adapter board at a location close to the power-consuming equipment at the power-consuming end, and the voltage value is fed back to a dedicated AC-DC transformer of the mains as a reference value for output voltage adjustment. When the voltage value at the power-consuming end is too high, the transformer lowers the voltage output value, and when the voltage value at the power-consuming end is too low, the transformer increases the voltage output value. The voltage value adjusted by feedback is stable, ensuring the voltage-stabilized power supply to the terminal power-consuming equipment, and finally achieving the purpose of stable voltage output, reducing the influence of voltage changes on the stability of the sound quality output of the audio equipment.

[0017] Among them, the DC adapter board 3 has a built-in voltage detection sensor component, and a connecting line 6 is installed between the power supply end of the DC adapter board 3 and the DC connector 5; through the built-in voltage detection sensor component in the DC adapter board 3, the instantaneous voltage value of the electrical equipment when using electricity is monitored in real time, and the connecting line 6 plays a role in connecting the power supply between the DC adapter board 3 and the DC connector 5.

[0018] Among them, the connection ends of the two-core power supply line 2 and the two-core feedback line 4 are both equipped with power supply connectors 7 and are electrically connected to the AC / DC transformer 1 through the power supply connector 7; the two-core power supply line 2 and the two-core feedback line 4 are both connected to the AC / DC transformer 1 through the power supply connector 7.

[0019] It should be noted that the utility model is a power cord for power supply and closed-loop feedback to instantly level the voltage. When in use, the power supply end of the AC-DC transformer 1 is connected to the AC power supply, which can convert the AC power into DC power and output it. At the same time, it can internally receive data feedback from voltage monitoring and adjust the output voltage. The DC connector 5 is connected to the power-consuming end of the speaker device. A two-core power supply line 2 and a two-core feedback line 4 are connected between the DC adapter board 3 and the AC-DC transformer 1 of the AC power supply. The built-in voltage sensor component of the DC adapter board 3 is used to collect the instantaneous voltage value during power consumption at a location close to the power-consuming equipment at the power-consuming end, and the voltage value is fed back to a dedicated AC-DC transformer of the AC power supply as a reference value for adjusting the output voltage. When the voltage value at the power-consuming end is too high, the transformer lowers the voltage output value. When the voltage value at the power-consuming end is too low, the transformer increases the voltage output value. The voltage value adjusted by feedback is stable, ensuring the voltage-stabilized power supply to the terminal power-consuming equipment, and finally achieving the purpose of stable voltage output, reducing the influence of voltage changes on the stability of the sound quality output of the audio equipment.
