Description

Technical Field

[0001] The invention belongs to the technical field of computer power supplies, and in particular relates to a microcomputer power supply with high efficiency and leakage prevention. Background Art

[0002] Computers are low-voltage products, which means that the operating voltage of their components is relatively low, generally within plus or minus 12 volts, and is direct current. Ordinary AC power is 220 volts (110 volts in some countries) alternating current, which cannot be used directly on computer components. Therefore, computers, like many home appliances, require a power supply part, which is responsible for converting ordinary AC power into a voltage that can be used by the computer. It is generally installed inside the computer, but the computer power supplies currently on the market have the safety hazard of leakage. When the computer is used for a long time, the wires will age and break. At this time, it is easy for the wires in the power supply wires to touch each other or the wires to touch the metal parts in the chassis, causing power leakage. When the computer power leaks, people cannot discover it, resulting in a short circuit inside the computer due to leakage, and the computer may be burned out, or the human body may be electrocuted when it touches the metal chassis of the computer.

[0003] An existing patent (publication number: CN109960362A) discloses a computer power supply that prevents leakage. The patent states that "it includes a power supply installation box, the bottom of the inner cavity of the power supply installation box is fixedly connected to the power supply bracket, and the power supply bracket includes a mounting block. A groove is provided on the top of the mounting block, and the inner wall of the groove is fixedly connected to the side surfaces of the mounting plate. The present invention protects the internal computer power supply by providing a power supply installation box to prevent leakage of the computer power supply, which may cause leakage of the host and thus cause electric shock accidents. The leakage protection box is fixed by the power supply bracket to prevent leakage of the leakage protection box from being directly transmitted to the power supply installation box. By providing a first through hole and a second through hole and connecting them through a conduit, leakage is prevented when the wire is broken and exposed to the air, thereby protecting the computer power supply and preventing leakage from causing a short circuit in the computer. At the same time, electric shock to the human body due to leakage of the computer power supply is prevented."

[0004] However, in the above patent, the power supply installation box is made of metal, which is conductive. The metal shell is in direct contact with the chassis. If leakage occurs in the internal circuit, the current may be transmitted to the human body through the chassis, causing the risk of electric shock. In addition, the power output harness lacks a fixed and organized structure, which may lead to poor contact due to looseness, and redundant cables are scattered in the chassis, affecting the heat dissipation airflow and increasing the risk of short circuit.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example:

[0030] See also Figures 1-8As shown, the present invention provides a technical solution: including a power supply body 1, a circuit board 101 is fixedly connected to the power supply body 1, an air inlet slot 102 is provided on one side of the power supply body 1, a cooling fan 103 is fixedly connected to the power supply body 1 by a first screw 105, a heat dissipation port 104 is provided at the bottom of the power supply body 1 corresponding to the position of the cooling fan 103, and an anti-leakage installation component is also included. The anti-leakage installation component includes an extension plate 201 arranged on both sides of the top of the power supply body 1, an insertion hole 202 is provided on the extension plate 201, and a connecting column 203 is rotatably connected to the top of the insertion hole 202, and the connecting column 203 includes an internal thread 2031 , insulating member 2032 and external thread 2033, the connecting column 203 is threadedly connected with a second screw 204, and an insulating washer 205 is provided at the bottom of the connecting column 203. The top two sides of the power supply body 1 are respectively fixedly connected with insulating plates 206. The power supply body 1 is electrically connected to other electronic components in the chassis. The power supply body 1 should be installed at the top of the rear of the chassis. If the power supply body 1 is installed at the bottom of the rear of the chassis, the anti-leakage installation component must be installed at the bottom of the power supply body 1, but the air still enters from the air inlet slot 102 and is discharged from the heat dissipation port 104. At this time, the bottom of the chassis needs to be raised to provide space for heat dissipation, or the cooling fan 103 is connected to the heat dissipation fan 103. The heat outlet 104 is located at the top of the power supply body 1, blowing the hot air into the chassis, and then dissipating the heat through the fan installed in the chassis. A partition 301 is fixedly connected to the power supply body 1, and a first threading hole 302 is provided on the partition 301. A cavity 303 is provided between the partition 301 and the power supply body 1. A second threading hole 304 corresponding to the position of the partition 301 is provided on one side of the power supply body 1. A vertical groove 305 is provided below the second threading hole 304. A threaded rod 306 is rotatably connected in the vertical groove 305. A splint 307 is threadedly connected to the threaded rod 306. A groove 308 that penetrates the power supply body 1 is provided at the bottom of the vertical groove 305. The bottom of the threaded rod 306 is located in the groove 308 and a rubbing block 309 is provided on the threaded rod 306. The first threading hole 302 and the second threading hole 304 are used to pass the connecting wires to connect the circuit board 101 to the computer motherboard and the plug-in on the computer motherboard. The top of the vertical slot 305 is located below the second threading hole 304. The power supply body 1 is a semi-module with a fixed wiring harness. If it is a full module, the wiring harness does not need to be fixed and needs to be fixed inside the chassis. The clamping plate 307 slides in the vertical slot 305. The groove 308 is located below the second threading hole 304. The rubbing block 309 protrudes from the power supply body 1.

[0031] In this embodiment, specifically, a baffle 401 is provided inside one side of the power supply body 1, a mounting plate 402 abuts against the baffle 401, a circular hole 403 is provided on the mounting plate 402, a third screw 404 passes through the circular hole 403, and the third screw 404 is threadedly connected to the baffle 401. The baffle 401 seals the interior of the power supply body 1 and facilitates disassembly;

[0032] In this embodiment, specifically: a power socket 501 is provided on one side of the power supply body 1, and a power switch 502 is provided on one side of the power socket 501;

[0033] In this embodiment, specifically: an expansion interface 6 is provided on one side of the power supply body 1 close to the second threading hole 304;

[0034] In this embodiment, specifically: the circuit board 101 is fixedly connected to the power supply body 1 by a plurality of groups of screws, the cooling fan 103 is located directly below the power supply body 1, and the head of the first screw 105 is located on the outside of the power supply body 1. The circuit board 101 is electrically connected to the cooling fan 103, and the air outside is absorbed through the air inlet slot 102. The air inlet slot 102 can play a preliminary filtering effect, reducing the dust from entering the power supply body 1. The air can only enter through the air inlet slot 102, which can prevent the heat generated by other electronic components in the computer case from being absorbed into the power supply body 1, thereby enhancing the heat dissipation effect and the use effect of the power supply body 1. The cooling fan 103 blows out the heat generated by the circuit board 101 when working, and the air inlet slot 102 faces the outside of the chassis. The head of the first screw 105 is located on the outside, which is convenient for disassembly and cleaning of the cooling fan 103. If the head of the air inlet slot 102 is located inside the power supply body 1, the space inside the power supply body 1 is small and inconvenient to operate.

[0035] In this embodiment, specifically: the internal thread 2031 and the external thread 2033 are made of stainless steel, the insulating member 2032 is made of rubber, the insulating member 2032 is wrapped around the internal thread 2031, the insulating washer 205 is made of rubber, the insulating washer 205 is attached to the top of the power supply body 1, the height of the insulating washer 205 is consistent with the height of the insulating plate 206, the insulating plate 206 is made of rubber, and the connecting column 203 is provided with four groups, and each extension plate 201 is provided with two connecting columns 203. The height of the second screw 204 is greater than the sum of the heights of the connecting column 203 and the extension plate 201. When installing the second screw 204, it is necessary to press the connecting column 203 so that the connecting column 203 cannot rotate. After the second screw 204 is screwed into the connecting post 203, one end of the second screw 204 fits against the inner top of the connecting post 203. Then, by rotating the second screw 204, the connecting post 203 is screwed into the computer case to fix the power supply body 1. The external and internal stainless steel external threads 2033 and internal threads 2031 enhance stability and durability after installation. The rubber insulating member 2032 isolates the internal threads 2031 and the insulating member 2032 to prevent leakage. The rubber material is insulated, and the insulating washer 205 and the insulating plate 206 fit closely against the inside of the case. Even if the power supply body 1 leaks, it can still play a good insulation role to avoid electric shock when touching the case.

[0036] In this embodiment, specifically: the partition 301 is located on one side of the power supply body 1 and the cooling fan 103, and the partition 301 is located on the side away from the air inlet slot 102, the height of the vertical slot 305 is greater than the height of the clamping plate 307, and the height of the clamping plate 307 is consistent with the height of the second threading hole 304. The cavity 303 between the partition 301 and the power supply body 1 can be used to place a long power cord to avoid it being arranged in the chassis and affecting the appearance. In addition, the rubbing block 309 protruding from the side of the power supply body 1 can conveniently drive the threaded rod 306 to rotate, and then push the clamping plate 307 to fix the power cord;

[0037] In this embodiment, specifically: the edge of the mounting plate 402 is fitted to the inner wall of the power supply body 1, the material of the mounting plate 402 is consistent with the material of the power supply body 1, a sealing ring is provided at the fitting point of the mounting plate 402 and the power supply body 1, three groups of circular holes 403 are provided, the diameter of the head of the third screw 404 is smaller than the diameter of the outside of the circular hole 403, and the circular hole 403 is composed of two circles with different diameters. The sealing ring can be set on the back of the mounting plate 402 or on the baffle 401 to reduce dust from entering from one side of the mounting plate 402 on the power supply body 1. The head of the third screw 404 is completely screwed into the circular hole 403, which can ensure the neatness of the outside of the power supply body 1, avoid difficulties in wiring the external wiring harness, and avoid scratches on people.

[0038] In this example, specifically: the power socket 501 and the power switch 502 are located on the same side of the air inlet slot 102 on the power supply body 1, the power socket 501 and the power switch 502 are electrically connected to the circuit board 101, the expansion interface 6 is electrically connected to the circuit board 101, the power socket 501 is used to supply power to the circuit board 101, and the power switch 502 can cut off the power to the circuit board 101 without disconnecting the power supply, thereby improving convenience, and the power cord connected to the motherboard can be expanded through the provided expansion interface 6, thereby improving versatility and improving the applicability of the power supply body 1 to a variety of motherboards.

[0039] Working principle or structural principle: When installing the power supply body 1 in the chassis, press the four connecting posts 203 in turn, and then screw the second screw 204 into the connecting post 203. At this time, the connecting post 203 needs to be kept from rotating to avoid rotating the connecting post 203 at the same time when the second screw 204 is rotated, until the second screw 204 is completely screwed into the connecting post 203, and the tail of the second screw 204 is in contact with the inner top of the connecting post 203. Then place the power supply body 1 in the installation position in the chassis so that the connecting post 203 corresponds to the installation position in the chassis, and by rotating the second screw 20 4 drives the connecting column 203 to rotate, thereby fixing the power supply body 1 in the chassis. At this time, the insulating washer 205 and the insulating plate 206 are attached to the top of the chassis. The insulating washer 205 and the insulating plate 206, as well as the insulating member 2032, can play an insulating role, so that the metal material on the power supply body 1 does not adhere to the chassis. Even if the power supply body 1 leaks, it will not be conducted to the chassis. Then, the power supply body 1 is connected to the mainboard circuit. The pre-arranged wiring harness on the circuit board 101 is passed through the first wire threading hole 302 and the second wire threading hole 304. After the circuit is connected, the excess wires are passed through the second wire threading hole. 304 is pushed into the cavity 303. At this time, the mounting plate 402 can be removed and the wires in the cavity 303 can be sorted from one side of the cavity 303. After sorting, rub the rubbing block 309 to drive the threaded rod 306 to rotate. At this time, the threaded rod 306 pushes the clamping plate 307 to slide downward in the vertical slot 305, thereby causing the clamping plate 307 to clamp and fix the wires passing through the second threading hole 304. The electrical connection of the expansion circuit on the circuit board 101 can be achieved through the expansion interface 6. The mounting plate 402 is fixed to the power supply body 1 through four third screws 404. When the interior is inspected or cleaned , only the third screw 404 needs to be removed. The heads of the four groups of first screws 105 are located on the outside of the power supply body 1, which is also convenient for removing the first screws 105, and then taking out the cooling fan 103 for cleaning. Then, the circuit board 101 is powered through the power socket 501. When the power socket 501 is connected, the start and stop of the circuit board 101 can be directly controlled by the power switch 502. When the circuit board 101 is started, the cooling fan 103 will be started, and then the external air will be absorbed through the air inlet slot 102 and discharged through the heat dissipation port 104 to dissipate heat for the electronic components on the circuit board 101.
