Technical Field

The invention relates to the technical field of computer power supply, in particular to a computer power supply overcurrent protection device and a use method thereof.

Background Art

With the development of science and technology, the field of computer servers is also facing great changes. In addition to the original X86 architecture, ARM will be increasingly used in the server field due to its excellent power consumption control and performance. In the power supply design of existing computer servers, it is necessary to design corresponding overcurrent protection (OCP) circuits according to different chip platforms, that is, according to the different designs and hardware specifications of the chip platforms. At the same time, power supply overcurrent protection for the computer is beneficial to improve the service life and safety of computer equipment. Therefore, overcurrent protection devices play an important role in computers.

A Chinese patent discloses a power supply monitoring device and an overcurrent protection method. (Publication No. CN103268144B), wherein the power supply monitoring device includes a mainboard monitoring unit, a digitally controlled potentiometer, a power consumption monitoring chip and a switch, wherein: the digitally controlled potentiometer is connected in series with a voltage divider resistor and connected between the VCAP pin and the ISET pin of the power consumption monitoring chip; the mainboard monitoring unit is used to obtain the configuration information of the mainboard, calculate the power consumption requirement of the mainboard according to the configuration information, determine the target resistance value of the digitally controlled potentiometer according to the power consumption requirement, and send a data signal to the digitally controlled potentiometer to adjust the resistance value of the digitally controlled potentiometer to the target resistance value; the power consumption monitoring chip is connected to the mainboard power supply through the switch, and when the mainboard current is monitored to exceed the current After the threshold is reached, the switch is turned off, thereby cutting off the mainboard power supply. The present invention realizes the use of the same overcurrent protection circuit to adapt to different chip platforms, thereby reducing development time and development costs; the above-mentioned power overcurrent protection method uses a monitoring current threshold to cut off the mainboard power supply after it is exceeded, thereby achieving overcurrent protection, but in the operation process, it is not conducive to controlling the power supply current according to the first overcurrent situation after the second power connection. The existing power overcurrent protection uses the method of cutting off the mainboard power supply.

As an implementation mode of the present invention, a negative pressure fan is installed below the power-connected copper plate, and a heat dissipation component is installed on one side of the negative pressure fan.

A method for using a computer power supply overcurrent protection device comprises the following steps:

S1: First, the power box is connected to the power copper plate through the wiring harness. The cable passes through the current sensor. After the power is turned on, the electromagnetic sheet generates magnetic force and attracts the magnetic block, so that the power copper plate is connected to the power copper block group. The current sensor senses the current. When the current is overcurrent, the mainboard power supply will be cut off.

S2: Secondly, before the power is turned on for the second time, open the cabinet door, unplug the line connector, disconnect the parallel line, use the drive motor to drive the gear to rotate, and the gear and the teeth cooperate with each other to drive the movable ring to rotate;

S3: After the movable ring rotates, the second inductor is brought close to the copper sheet, and the copper sheet is connected to the second inductor through the energized copper plate. An inductor is added to the cable, and the magnetic field intervention of the inductor is used to limit the power current, which is conducive to adjusting and controlling the circuit current based on the first overcurrent condition.

Compared with the prior art, the present invention has the following beneficial effects:

1. The connection between the power supply box and the internal circuit of the computer is made of a power-connected copper plate and a power-carrying copper block group. A magnetic block is arranged on the surface of the power-connected copper plate. The magnetic block is adsorbed by an electromagnetic sheet arranged on the back of the power-carrying copper block group. After power is turned on, the electromagnetic sheet will generate magnetic force, and then magnetically attract the magnetic block, so that the power-connected copper plate and the power-carrying copper block group are connected together. When the current sensor senses that the current flow is overloaded, the mainboard power is cut off, and the magnetic force of the electromagnetic sheet disappears. Under the influence of the elastic force of the rebound airbag on the back of the power-connected copper plate, the power-connected copper plate and the power-carrying copper block group are separated, which is conducive to the power supply end being completely cut off, thereby ensuring the safety of the power supply end;

2. Through the setting of the inductor component, the inductor component is composed of a mounting ring and a ring group component. The ring group component is distributed in a ring shape on the mounting ring. At the same time, a movable ring is installed at the front end of the mounting ring. A ring seat is fixed on the surface of the movable ring. The ring seat has the same structure as the ring group component. Inductors are installed on the ring group component and the ring seat. The power cable and the first inductor are connected to each other, while the second inductor is not directly connected to the power cable. When an overcurrent occurs, the mainboard power is cut off and the power is connected again. The second inductor is connected to the power cable by rotating the movable ring. By adding the inductor, the magnetic field intervention of the inductor is used to limit the power current, which is conducive to adjusting and controlling the amount of circuit current based on the first overcurrent.

3. The two ends of the coil of the first inductor are connected to the power cable, and at the same time, a parallel line is electrically connected to the position of the power cable corresponding to the second inductor. When the mainboard power is started for the second time, the line connector is unplugged and the parallel line is disconnected. The movable ring rotates to bring the second inductor close to the copper sheet set on the power cable. The energized copper plate contacts the copper sheet, and the power cable is connected to the two ends of the coil of the second inductor, so that two sets of inductors are installed on the power cable at intervals at the same time. By adding the inductor, it is beneficial to adjust and control the amount of circuit current based on the first overcurrent situation.
