Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer accessories technology, specifically a computer power supply that prevents leakage. Background Technology
[0002] The computer power supply converts the alternating current from the mains grid into stable and reliable direct current of different voltages to power system components inside the computer case, such as the system board, various adapters and expansion cards, hard disk drives, optical disk drives, keyboard, and mouse. It is one of the most important components in a computer.
[0003] Existing computer power supplies have wiring harnesses plugged into the back and surface during operation, and the sides come into contact with the chassis and chassis cover. Therefore, the cooling airflow can only be set up in the top, bottom and partial surface areas. Since the top of the power supply is usually the graphics card, the computer power supply mainly uses bottom suction and front exhaust, and the airflow is separate from the airflow of the computer host.
[0004] This airflow design means the filter needs to be installed inside the chassis, at the bottom or bottom. After prolonged use, when the filter becomes clogged and needs cleaning, the side panel along the cable routing direction of the chassis needs to be removed before cleaning the filter. This method is cumbersome and time-consuming. Alternatively, the chassis can be lifted up to clean the filter, but the chassis is heavy due to the power supply, motherboard, and wiring inside, making this cleaning method laborious and inconvenient. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a computer power supply that prevents leakage current, so as to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a leakage-proof computer power supply, comprising a power supply body, a bracket fixed at the bottom of the power supply body, a placement rack connected to the top of the bracket, a support frame connected to the bottom middle of the placement rack, a flexible magnetic strip connected to the top of the support frame, and a flexible filter screen connected inside the flexible magnetic strip; a through hole is opened at the bottom of the placement rack, a damping shaft is installed below the outer surface of the power supply body, and a limit plate is connected to the bottom of the damping shaft.
[0007] By adopting the above technical solution, when the flexible filter needs cleaning, the operator can rotate the limiting plate upwards to move it out of the through hole, thereby ending the limitation on the placement rack. The operator can then pull out the placement rack, guided by the bracket, thus pulling out the flexible filter along with it. The operator can then remove the flexible filter for cleaning. If there is an obstruction in front of the placement rack, limiting its pulling distance, the operator can bend the flexible magnetic strip and the flexible filter into an L-shape and pull them out, since both the magnetic strip and the filter are flexible. After cleaning, the operator places the flexible filter back into the groove at the top of the placement rack, where it is attracted to the support by the flexible magnetic strip. The shelf is positioned to limit the movement. If there is an obstruction in front of the shelf that restricts its extension distance, the operator can bend the flexible magnetic strip and flexible filter into an L-shape when placing them into the groove at the top of the shelf. During this process, the support frame guides the flexible filter and flexible magnetic strip to prevent them from bending downwards and deforming, which could cause the structure to jam and prevent them from being fully installed. The support frame is also hollow to avoid affecting the entry of heat dissipation airflow. Afterward, the operator pushes the shelf back into the bracket and then rotates the limiting plate downwards to make it enter the through hole and hold it in place, thus preventing the shelf from slipping out. Gravity combined with a damping shaft prevents the limiting plate from rotating arbitrarily, improving the limiting effect.
[0008] Furthermore, a groove is provided on the top of the placement rack.
[0009] By adopting the above technical solution, after cleaning, the operator puts the flexible filter back into the groove at the top of the placement frame, and the flexible magnetic strip is used to attach it to the support frame to complete the positioning.
[0010] Furthermore, the support frame is made of iron material, and the flexible magnetic strip is detachably connected to the support frame.
[0011] By adopting the above technical solution, if there is an obstruction in front of the placement rack that limits the distance the placement rack can be pulled out, the operator can bend the flexible magnetic strip and flexible filter into an L-shape when placing them into the groove at the top of the placement rack, and then use the flexible magnetic strip to attach them to the support frame to complete the positioning.
[0012] Furthermore, the top and bottom of the support frame are both hollowed out.
[0013] By adopting the above technical solution, the flexible filter and flexible magnetic strip are guided by the support frame, which prevents the flexible magnetic strip and flexible filter from bending and deforming downwards, which would cause the structure to jam and prevent it from being fully installed. In addition, the support frame structure is hollow to avoid affecting the entry of heat dissipation airflow.
[0014] Furthermore, the limiting plate is rotatably connected to the power supply body via a damping shaft, and the limiting plate abuts against the through hole.
[0015] By adopting the above technical solution, when the flexible filter needs to be cleaned, the operator can rotate the limiting plate upward to move the limiting plate out of the through hole, thereby ending the limitation on the placement rack.
[0016] Furthermore, the placement rack is slidably connected to the bracket and the power supply body, respectively.
[0017] By adopting the above technical solution, the operator can pull out the placement rack, and guide the placement rack with the bracket during the process, thereby pulling out the flexible filter screen together.
[0018] Furthermore, a power interface is installed on one side of the outer surface of the power supply body, a control switch is installed on the other side of the outer surface of the power supply body, an air outlet filter is provided in the middle of the outer surface of the power supply body, an air inlet is provided in the middle of the bottom of the power supply body, a wiring board is installed on the back of the power supply body, and mounting holes are provided above and below the outer surface of the power supply body.
[0019] By adopting the above technical solution, the operator inserts the power supply unit into the chassis by passing the insulating bolt through the mounting hole. Then, the operator connects the wiring harness inside the computer to the junction box and connects the power interface to the power grid through the power cord. After preparation, the operator presses the control switch to turn on the power. When the power supply unit is working, the built-in fan inside the power supply unit starts to rotate to generate airflow, thereby dissipating heat from the electronic components inside the power supply unit. The airflow enters from the bottom air inlet and is discharged from the air outlet filter.
[0020] Furthermore, insulating feet are connected to both sides of the top of the power supply body, both sides of the bottom of the power supply body, both sides of the top of the terminal block, and both sides of the bottom of the terminal block.
[0021] By adopting the above technical solution, when the power supply is working, the contact between the power supply and the chassis is separated by eight insulating feet. At the same time, the bracket, placement rack and limit plate are also made of plastic and have insulation properties, just like the insulating feet. Furthermore, due to the use of insulating bolts for installation, leakage from the power supply to the chassis is prevented, thus avoiding electric shock to the operator when turning on the power.
[0022] Furthermore, the insulating feet, brackets, placement racks, and limiting plates are all made of POM material.
[0023] By adopting the above technical solution, the bracket, placement rack, and limiting plate are all made of plastic, which has insulation properties, just like the insulating feet. Furthermore, the POM material bracket, placement rack, and limiting plate have a low coefficient of friction, reducing wear during the extraction and insertion of the structure.
[0024] In summary, the present invention has the following main advantages:
[0025] 1. This utility model, through the design of a bracket, a placement rack, a through hole, a damping shaft, and a limiting plate, allows for easy cleaning. When cleaning is required, the limiting plate can be rotated upwards to move out of the through hole, thus ending the limitation on the placement rack. The placement rack can then be pulled out, guided by the bracket, allowing the flexible filter screen to be pulled out along with it. After cleaning, the flexible filter screen is placed back into the groove at the top of the placement rack. The placement rack is then pushed back into the bracket, and the limiting plate is rotated downwards to enter the through hole and hold it in place, preventing the placement rack from slipping out. Gravity, combined with the damping shaft, prevents the limiting plate from rotating arbitrarily, improving the limiting effect. The filter screen can be removed and cleaned without disassembling or lifting the casing, making the operation simple, convenient, time-saving, and labor-saving.
[0026] 2. This utility model, through the arrangement of a support frame, flexible magnetic strips, and a flexible filter, utilizes the flexibility of both the magnetic strips and the filter. Since the magnetic strips and filter are flexible, if there is an obstruction in front of the placement frame limiting its removal distance, the flexible magnetic strips and filter can be bent into an L-shape during removal to facilitate their removal and cleaning. Similarly, when placing the flexible magnetic strips and filter into the groove at the top of the placement frame, they can also be bent into an L-shape. During this process, the support frame guides the flexible filter and magnetic strip, preventing them from bending downwards and deforming, which could cause the structure to jam and prevent complete insertion. Furthermore, the openwork structure of the support frame prevents obstruction of heat dissipation airflow, reducing the occurrence of situations where space constraints prevent the filter from being disassembled and cleaned.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0033] The embodiments of this utility model will be described below based on its overall structure.
[0034] Example 1:
[0035] A type of computer power supply that prevents leakage current, such as Figures 1-4 As shown, the device includes a power supply body 1, a bracket 9 fixed to the bottom of the power supply body 1, and a placement rack 10 connected to the top of the bracket 9. The placement rack 10 is slidably connected to both the bracket 9 and the power supply body 1. A groove is formed at the top of the placement rack 10, and a support frame 14 is connected to the middle of the bottom of the placement rack 10. The support frame 14 is made of iron and has open top and bottom sections. A flexible magnetic strip 15 is connected to the top of the support frame 14 and is detachably connected to the support frame 14. A flexible filter 16 is connected inside the flexible magnetic strip 15. A through hole 11 is formed at the bottom of the placement rack 10. A damping shaft 12 is installed below the outer surface of the power source body 1. A limiting plate 13 is connected to the bottom of the damping shaft 12. The limiting plate 13 is rotatably connected to the power source body 1 through the damping shaft 12. The limiting plate 13 abuts against the through hole 11. When the flexible filter 16 needs to be cleaned, the operator can rotate the limiting plate 13 upward to move the limiting plate 13 out of the through hole 11, thereby ending the limitation on the placement rack 10. At this time, the operator can pull out the placement rack 10. During this process, the bracket 9 guides the placement rack 10, thereby pulling out the flexible filter 16 together. Afterwards, the operator can remove the flexible filter 16. Remove the filter 16 for cleaning. If there is an obstruction in front of the placement rack 10, limiting its extension distance, the operator can bend the flexible magnetic strip 15 and the flexible filter 16 into an L-shape and pull them out, since both the magnetic strip and the filter are flexible. After cleaning, the operator puts the flexible filter 16 back into the groove at the top of the placement rack 10, where it is held in place by the flexible magnetic strip 15 adhering to the support frame 14. If there is an obstruction in front of the placement rack 10, limiting its extension distance, the operator can place the flexible magnetic strip 15 and the flexible filter 16 into the groove at the top of the placement rack 10. When in the slot, it can also be bent into an L-shape. During this process, the support frame 14 guides the flexible filter 16 and the flexible magnetic strip 15 to prevent the flexible magnetic strip 15 and the flexible filter 16 from bending downwards and deforming, which would cause the structure to jam and prevent it from being fully installed. The support frame 14 is also hollow to avoid affecting the entry of heat dissipation airflow. After that, the operator pushes the placement frame 10 back into the bracket 9. The operator then rotates the limiting plate 13 downwards so that the limiting plate 13 enters the through hole 11 and abuts against it, thereby preventing the placement frame 10 from slipping out. The gravity combined with the damping shaft 12 prevents the limiting plate 13 from rotating arbitrarily, thus improving the limiting effect.
[0036] See Figures 1-3 In the above embodiment, a power interface 2 is installed on one side of the outer surface of the power supply body 1, a control switch 3 is installed on the other side of the outer surface of the power supply body 1, an air outlet filter 6 is provided in the middle of the outer surface of the power supply body 1, an air inlet 7 is provided in the middle of the bottom of the power supply body 1, a junction box 4 is installed on the back of the power supply body 1, and mounting holes 5 are provided above and below the outer surface of the power supply body 1. The operator inserts the power supply body 1 into the chassis by passing an insulating bolt through the mounting holes 5. Then the operator connects the wiring harness inside the computer to the junction box 4 and connects the power interface 2 to the power grid through the power cord. After preparation, the operator presses the control switch 3 to turn on the power. When the power supply body 1 is working, the fan inside the power supply body 1 starts to rotate to generate airflow to dissipate heat from the electronic components inside the power supply body 1. The airflow enters from the bottom air inlet 7 and is discharged from the air outlet filter 6. The incoming airflow is filtered by the flexible filter 16 to reduce the dust entering the power supply body 1.
[0037] Example 2:
[0038] Based on the above embodiment one, in order to reduce the occurrence of leakage current, the following settings are now implemented.
[0039] See Figures 1-4 In the above embodiment, insulating feet 8 are connected to the top two sides, bottom two sides, top two sides, and bottom two sides of the terminal block 4. The insulating feet 8, brackets 9, placement racks 10, and limiting plates 13 are all made of POM material. When the power supply body 1 is working, the eight insulating feet 8 separate the power supply body 1 from the chassis. At the same time, the brackets 9, placement racks 10, and limiting plates 13 are also made of plastic and have insulation properties, just like the insulating feet 8. Furthermore, the use of insulating bolts for installation prevents the power supply body 1 from leaking current to the chassis, thus avoiding electric shock to the operator when turning on the power. Moreover, the POM material brackets 9, placement racks 10, and limiting plates 13 have a low coefficient of friction, reducing wear during the pulling out and pushing in of the structure.
[0040] The implementation principle of this utility model is as follows: First, the operator inserts the power supply body 1 into the chassis through the mounting hole 5 with an insulating bolt. Then, the operator connects the wiring harness inside the computer to the terminal block 4 and connects the power interface 2 to the power grid through the power cord. After preparation, the operator presses the control switch 3 to turn on the power.
[0041] When the power supply unit 1 is working, the built-in fan inside the power supply unit 1 starts to rotate to generate airflow, thereby dissipating heat from the electronic components inside the power supply unit 1. The airflow enters from the bottom air inlet 7 and is discharged from the air outlet filter 6. The incoming airflow is filtered by the flexible filter 16 to reduce the dust entering the power supply unit 1.
[0042] When the flexible filter 16 needs cleaning, the operator can rotate the limiting plate 13 upward to move the limiting plate 13 out of the through hole 11, thereby ending the limitation on the placement rack 10. At this time, the operator can pull out the placement rack 10. During this process, the bracket 9 guides the placement rack 10, thereby pulling out the flexible filter 16 together. After that, the operator can remove the flexible filter 16 for cleaning. If there is an obstruction in front of the placement rack 10, which limits the distance that the placement rack 10 can be pulled out, since both the magnetic strip and the filter are flexible, the operator can bend the flexible magnetic strip 15 and the flexible filter 16 into an L-shape and pull them out.
[0043] After cleaning, the operator places the flexible filter 16 back into the groove at the top of the placement rack 10, where it is held in place by the flexible magnetic strip 15 adhering to the support frame 14. If there is an obstruction in front of the placement rack 10, limiting its extension distance, the operator can bend the flexible magnetic strip 15 and the flexible filter 16 into an L-shape when placing them into the groove at the top of the placement rack 10. During this process, the support frame 14 guides the flexible filter 16 and the flexible magnetic strip 15 to prevent them from bending and deforming downwards, which could cause the structure to jam and prevent them from being fully installed. The support frame 14 is also hollow to avoid affecting the entry of heat dissipation airflow. Afterward, the operator pushes the placement rack 10 back into the bracket 9, and then rotates the limiting plate 13 downwards so that it enters the through hole 11 and blocks it, thus preventing the placement rack 10 from slipping out. Gravity combined with the damping shaft 12 prevents the limiting plate 13 from rotating arbitrarily, improving the limiting effect.
[0044] Furthermore, when the power supply body 1 is working, the contact between the power supply body 1 and the chassis is separated by eight insulating feet 8. At the same time, the bracket 9, the placement rack 10 and the limiting plate 13 are also made of plastic and have insulation properties, just like the insulating feet 8. In addition, due to the use of insulating bolts for installation, leakage of current from the power supply body 1 to the chassis is prevented, which could cause the operator to be shocked when turning on the power. Moreover, the bracket 9, the placement rack 10 and the limiting plate 13 made of POM material have a low coefficient of friction, which reduces wear when the structure is pulled out and pushed in.
