Description

Technical Field

[0001] The utility model relates to the technical field of power supply boards, and particularly relates to a highly reliable power supply board. Background Art

[0002] The power supply board is an important part of the display drive system or other drive systems, responsible for controlling the power supply of the drive circuit, that is, the on and off of the switching tube, and boosting the voltage of the transformer when lighting to provide sufficient drive voltage, and keeping the output current stable when the circuit is working; however, in the actual use process of the existing power supply board, there are some deficiencies, such as:

[0003] A highly reliable on-board isolated power supply with the publication number of CN209562394U. This power supply board can effectively prevent the left and right sides of the on-board power supply body from expanding outwards. The groove at the upper end of the slot part slides into the isolation frame, and the lower sides of both sides of the isolation frame are connected to the inner groove of the slot part by means of resin glue bonding. Therefore, the position of the isolation frame is fixed and is electrically isolated from the circuit board body through the slot part. The isolation frame covers the on-board power supply body, which can effectively isolate and limit the on-board power supply body, and effectively prevent the on-board power supply body from expanding forwards and backwards. Therefore, when the on-board power supply body expands due to heat, it can protect the electrical components on its side from being pressed by the on-board power supply body. However, in the actual use process, since it is difficult for this power supply board to effectively dissipate heat, it may cause the problem that the heat is too large when the device is in use, resulting in a decrease in the reliability of the power supply board, thereby reducing the protection and reliability of the device when in use. Summary of the Invention

[0004] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the utility model is to provide a highly reliable power supply board.

[0005] The purpose of the utility model is achieved by the following technical solutions: A highly reliable power supply board includes a device box and a top cover connected to the device box. An electronic board is arranged inside the device box, and connection circuits are arranged at both the left and right ends of the electronic board. A heat conducting sheet is connected to the bottom of the electronic board. A breathable sheet is connected to the bottom of the device box, and the bottom of the heat conducting sheet is fixedly attached to the top of the breathable sheet. A suction cup is connected to the bottom of the device box, and the breathable sheet is located on the top of the suction cup.

[0006] The rear end of the top of the device box is hinged to the top cover through a hinge, and a heat insulation film is arranged inside the top cover. A socket body is connected to the top of the electronic board, and the top of the socket body is attached to the top cover.

[0007] By providing a heat-conducting sheet at the bottom of the device box, and the heat-conducting sheet being in contact with the bottom of the electronic board, when the electronic board is working, the heat-conducting sheet can absorb the heat dissipated by the electronic board, and then the heat is discharged through the air-permeable sheet provided at the bottom of the device box. When the components inside the device box are operating, the temperature can be dissipated through the heat-conducting sheet and the air-permeable sheet, thereby reducing the internal temperature, and increasing the stability and reliability of the device during operation.

[0008] As a preferred technical solution of the present utility model, a resistance wire and a connector are provided on the top of the electronic board, the resistance wire is connected to the connection circuit, and the resistance wire is electrically connected to the connector, and the connection circuit is electrically connected to the electronic board through the connector.

[0009] Adopting the above technical solution can make it impossible for the current inside the connection circuit to be transmitted to the inside of the connector through the resistance wire as a medium when the temperature of the connection circuit is too high and the resistance wire is burned out, so that the device stops working when the temperature is too high, increasing the protection of the device.

[0010] As a preferred technical solution of the present utility model, a first buckle and a second buckle are connected to the front end of the top cover, and the top cover is snap-connected to the front end of the top of the device box through the first buckle and the second buckle.

[0011] Adopting the above technical solution can make the connection between the top cover and the device box more stable when they are connected and fixed, thereby increasing the firmness of the device during installation, and making the device box and the top cover better protect the electronic board device.

[0012] As a preferred technical solution of the present utility model, a fixing bolt is provided inside the first buckle, and the first buckle is fixedly connected to the device box through the fixing bolt.

[0013] Adopting the above technical solution can make the first buckle be connected to the device box through the fixing bolt when they are fixedly connected, thereby increasing the stability of the device during installation.

[0014] As a preferred technical solution of the present utility model, sleepers are provided at the bottom of the device box, the top of the sleepers is fixedly connected to the electronic board, and the device box fixes the heat-conducting sheet through the sleepers.

[0015] Adopting the above technical solution can make the device box fix the electronic board and other devices through the sleepers when fixing them, thereby increasing the stability of the device during installation.

[0016] As a preferred technical solution of the present utility model, the heat-conducting sheet is a metal heat dissipation fin mechanism, and the heat-conducting sheet and the electronic board on the top form a detachable connection. The metal heat dissipation fin mechanism is composed of aluminum L-shaped iron sheets and is fixed through a metal connecting shaft.

[0017] Adopting the above technical solution can make the heat-conducting sheet more stable when dissipating heat from devices such as electronic boards, thereby increasing the heat dissipation performance of the device.

[0018] As a preferred technical solution of the present utility model, the heat insulation film is attached to the bottom of the top cover, and the bottom of the heat insulation film is in contact with the socket body and the support columns.

[0019] Adopting the above technical solution can make the heat insulation film more obvious in protecting the socket body, and by supporting the four corners of the heat insulation film through the support columns, it can avoid the situation that the heat insulation film warps around due to overheating inside the device box.

[0020] The beneficial effects of the present utility model are as follows: by providing a heat-conducting sheet at the bottom of the device box and the heat-conducting sheet being in contact with the bottom of the electronic board, when the electronic board is working, the heat-conducting sheet can absorb the heat dissipated by the electronic board, and then the heat is discharged through the air-permeable sheet provided at the bottom of the device box. It can make the components inside the device box dissipate heat through the heat-conducting sheet and the air-permeable sheet during operation, thereby reducing the internal temperature, and thus increasing the stability and reliability of the device during operation;

[0021] Furthermore, through the arrangement of the first buckle and the second buckle, when the top cover is connected and fixed to the device box, it can be more stable, thereby increasing the firmness of the device during installation and enabling the device box and the top cover to better protect the electronic board device;

[0022] Through the arrangement of the resistance wire and the connector, when the temperature of the connection circuit is too high and the resistance wire is burned out, the current inside the connection circuit cannot be transmitted to the inside of the connector through the resistance wire as a medium, so that the device stops working when the temperature is too high, increasing the protection of the device.

Detailed implementation mode

[0029] For the convenience of those skilled in the art to understand, the following further describes the present invention in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation mode does not limit the present invention.

[0030] In order to solve the problem that the power supply board overheats during operation in the prior art, which leads to a decrease in the reliability of the device during use, the following solution is disclosed. Please refer to Figures 1-5 , the present invention provides a technical solution: a highly reliable power supply board, including a device box 1 and a top cover 2 connected to the device box 1.

An air permeable sheet 13 is connected to the bottom of the device box 1, and the bottom of the heat conducting sheet 12 is fixedly attached to the top of the air permeable sheet 13. A suction cup 3 is connected to the bottom of the device box 1, and the air permeable sheet 13 is located on the top of the suction cup 3;

[0031] The rear end of the top of the device box 1 is hinged to the top cover 2 through a hinge, and a heat insulation film 4 is provided inside the top cover 2. A socket body 10 is connected to the top of the electronic board 9, and the top of the socket body 10 is attached to the top cover 2;

[0032] When using this device, first fix the electronic board 9 inside the device box 1, and then connect the top cover 2 to the device box 1, so as to fix devices such as the electronic board 9 and the socket body 10. At this time, the electronic board 9 will be attached to the heat conducting sheet 12 provided at the bottom of the device box 1, so that during the use of the electronic board 9 and the socket body 10, the heat emitted by the electronic board 9 is absorbed by the heat conducting sheet 12, and then the hot air is discharged to the outside of the device box 1 through the air permeable sheet 13 provided at the bottom of the device box 1;

[0033] A resistance wire 15 and a connector 16 are provided on the top of the electronic board 9. The resistance wire 15 is connected to the connection circuit 8, and the resistance wire 15 is electrically connected to the connector 16. The connection circuit 8 is electrically connected to the electronic board 9 through the connector 16; The front end of the top of the top cover 2 is connected with a first buckle body 6 and a second buckle body 14, and the top cover 2 is snap-connected to the front end of the top of the device box 1 through the first buckle body 6 and the second buckle body 14;

[0034] A fixing bolt 7 is provided inside the first buckle body 6, and the first buckle body 6 is fixedly connected to the device box 1 through the fixing bolt 7; a sleeper 11 is provided at the bottom of the device box 1, and the top of the sleeper 11 is fixedly connected to the electronic board 9, and the device box 1 fixes the heat sink 12 through the sleeper 11; the heat sink 12 is a metal heat dissipation fin mechanism, and the heat sink 12 and the electronic board 9 at the top form a detachable connection; the heat insulation film 4 is attached to the bottom of the top cover 2, and the bottom of the heat insulation film 4 is attached to the socket body 10 and the support column 5;

[0035] When the temperature inside the device box 1 or the connector 16 is too high, the resistance wire 15 will fuse, so that the connection circuit 8 cannot form a transmission medium with the connector 16, so that the current inside the connection circuit 8 cannot be transmitted to the inside of the electronic board 9, causing the electronic board 9 to stop working forcibly. When the device box 1 is fixed, it can be adsorbed to other devices through the suction cup 3. Since the suction cup 3 is spaced from the air permeable piece 13 by a certain distance, it will not affect the heat dissipation inside the device box 1.

[0036] Working principle: When using this device, first fix the electronic board 9 inside the device box 1, and then connect the top cover 2 to the device box 1 to fix devices such as the electronic board 9 and the socket body 10. At this time, the electronic board 9 will be attached to the heat sink 12 provided at the bottom of the device box 1, so that during the use of the electronic board 9 and the socket body 10, the heat sink 12 absorbs the heat dissipated by the electronic board 9, and then discharges the hot air to the outside of the device box 1 through the air permeable piece 13 provided at the bottom of the device box 1;

[0037] When the temperature inside the device box 1 or the connector 16 is too high, the resistance wire 15 will fuse, so that the connection circuit 8 cannot form a transmission medium with the connector 16, so that the current inside the connection circuit 8 cannot be transmitted to the inside of the electronic board 9, causing the electronic board 9 to stop working forcibly. When the device box 1 is fixed, it can be adsorbed to other devices through the suction cup 3. Since the suction cup 3 is spaced from the air permeable piece 13 by a certain distance, it will not affect the heat dissipation inside the device box 1.

[0038] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
