Description

Technical Field

[0001] The present invention relates to the technical field of power transmission, and in particular to a power supply device with high safety. Background Art

[0002] Common power supply equipment is mainly industrial or household socket strips, which are multi-sockets with wires, also known as power strips or power strips. Their scientific name is wire extension assembly or extension cord socket. A socket strip refers to a multi-socket with power cords and plugs that can be moved. More than one power plug can be connected, which saves both space and lines.

[0003] However, the existing equipment has the following shortcomings: During the use of extension strips, current overload, aging of wires and incorrect plugging can all lead to short circuits. Traditional equipment needs to have certain protection capabilities, but current continues to be introduced into the equipment. The accumulated energy can still cause components to burn, causing open flames and resulting in dangerous accidents.

[0004] Therefore, we propose a highly safe power supply device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a highly safe electric power supply device. When the equipment is working, the instantaneous energy generated by the short circuit will force the fuse in the fuse assembly to burn out and break, thereby disconnecting the closed loop formed with the power supply platform. At the same time, the current in the third wire is interrupted, and the current sensor that loses the current introduction has a measured value that quickly returns to zero. The signal is quickly fed back to the equipment system, and then the system inputs the control command into the electric push rod through the internal wiring and information line. The electric push rod starts to work, and its inner shaft quickly extends outward from the cavity, exerting pressure on the back side of the power supply platform to push outward, and utilizing the movable connectivity of the adapter slide and the T-shaped slide bar to make the power supply platform move forward quickly until each conductive blade is completely separated from the inside of a corresponding metal copper cover, so as to solve the problems raised by the above-mentioned background technology.

The equipment adopts a double protection method. The former uses the high-voltage pulse generated by the short circuit to quickly fuse the fuse component to achieve the purpose of disconnecting the closed loop and prevent the current from continuing to pass through the short circuit. The latter uses electrical component detection and mechanical component assistance to push the power supply component away in time, so that it is completely separated from the energy input and current is prevented from still entering the power supply component. This method can maximize the suppression of burning of power supply equipment and reduce the probability of dangerous accidents. BRIEF DESCRIPTION OF THE DRAWINGS

On the one hand, the current introduced into the device can be evenly distributed to each first metal copper plate 29, and then transmitted to each second metal copper plate 32 by the second wire 35, so that current enters a group of conductive blades 8. By utilizing the close connection between the conductive blades 8 and the metal copper cover 11, the power supply to the power supply platform 5 is completed, and the plug of the power-consuming machine can be connected to the socket 36. On the other hand, the introduced energy can power multiple electrical components contained in the device.

At the same time, the current in the third wire 37 is interrupted, and the current sensor 19 that loses the current introduction, the measured value quickly returns to zero, and its signal is quickly fed back to the equipment system, and then the system inputs the control command into the electric push rod 22 through the internal wiring and information line 24, then the electric push rod 22 starts to work, and its inner shaft quickly extends outward from the cavity, exerting pressure on the reverse side of the power supply platform 5 to push outward, and utilizing the movable connectivity of the adapter slide 3 and the T-shaped slide bar 4 to make the power supply platform 5 move forward quickly until each conductive blade 8 is completely separated from the corresponding metal copper cover 11, so as to achieve complete separation of the power supply platform 5 from the energy input component.
