Description

Technical Field

[0001] The utility model relates to the field of isolation covers, in particular to an anti-shielding isolation cover. Background Art

[0002] In electronic devices, different circuit components or modules generate electromagnetic fields when they are working. Without a shielding cover, these electromagnetic fields may interfere with each other.

[0003] China Authorization Publication No. CN216600589U discloses a computer network security shielding isolation cover, comprising an isolation cover body and a network security isolator. A fixing plate is fixedly mounted on one inner wall of the isolation cover body, a fixing frame is fixedly mounted on one side of the fixing plate, and the network security isolator is disposed within the fixing frame. The top and bottom inner walls of the isolation cover body are each provided with a mounting slot and a slide slot, and a rotating shaft is rotatably mounted within each mounting slot. The utility model drives fan blades to rotate to ventilate and dissipate heat for the network security shielding isolation cover, while also driving a brush to move up and down to clean the dust screen, preventing clogging and ensuring effective heat dissipation.

[0004] However, this device has the following drawbacks: The device uses rotating fan blades to force airflow through the dust screen to dissipate heat from the equipment inside the isolation cover. However, since the isolation cover is equipped with a dust screen, electromagnetic waves can pass through the dust screen and enter the isolation cover, thereby affecting the device's anti-shielding performance. To address these drawbacks, we propose an anti-shielding isolation cover. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an anti-shielding isolation cover.

[0006] In order to solve the problems existing in the prior art, the present invention adopts the following technical solutions: an anti-shielding isolation cover, comprising:

[0007] The isolation cover body includes an outer shell and a cover fixedly mounted on the right side of the outer shell. The outer shell is composed of a shielding cover, assembly grooves are respectively provided on the lower surface and left side of the shielding cover, and an L-shaped heat conducting plate fixedly mounted on the inner wall of the assembly groove;

[0008] A heat dissipation structure comprising an L-shaped heat dissipation cover, a heat dissipation fan fixedly mounted on the upper surface of the L-shaped heat dissipation cover, heat dissipation fins fixedly mounted on the surface of the L-shaped heat conducting plate, and an air inlet opened on the right side of the L-shaped heat dissipation cover;

[0009] The assembly structure is arranged between the shell and the L-shaped heat dissipation cover, and is used to assemble the L-shaped heat dissipation cover and the shell into one body.

[0010] Preferably, the shielding cover and the cover plate are both made of conductive plastic.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By setting an isolation cover body and a heat dissipation structure, after the device is placed inside the shell, the shielding cover and cover plate made of conductive plastic, and the L-shaped heat conducting plate made of copper plate can be used to shield external electromagnetic waves. When the device generates heat during operation, the heat will be transferred to the heat dissipation fins through the L-shaped heat conducting plate, and then the heat dissipation fan can be driven to make the air flow enter the L-shaped heat dissipation cover along the air inlet and be discharged from the exhaust port of the heat dissipation fan, so that the high-speed air flow can be used to pass through the heat dissipation fins to dissipate the heat of the heat dissipation fins, and then the interior of the isolation cover body can be cooled. Compared with the existing technology, the device uses the L-shaped heat conducting plate and the heat dissipation fins to transfer the heat inside the shielding cover to the heat dissipation fins and the L-shaped heat conducting plate, and then the heat dissipation fan can drive the air flow to take away the heat on the heat dissipation fins and the L-shaped heat conducting plate, thereby avoiding the need to open air flow holes on the surface of the isolation cover body to cause electromagnetic waves to enter the isolation cover body, thereby effectively improving the electromagnetic wave shielding performance of the device.

[0019] 2. By setting up an assembly structure, pressing the limit pin can drive the limit pin out of the limit groove, so that the L-shaped heat dissipation cover can be removed from the surface of the shielding cover, and the L-shaped heat conduction plate and heat dissipation fins can be exposed, so that the dust attached to the L-shaped heat conduction plate and heat dissipation fins can be removed to prevent dust accumulation from affecting its heat dissipation.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-8 The utility model provides a technical solution: an anti-shielding isolation cover, including: an isolation cover body, a heat dissipation structure and an assembly structure.

[0032] See Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6The isolation cover body includes an outer shell and a cover plate 10 fixedly installed on the right side of the outer shell. The outer shell consists of a shielding cover 11, assembly grooves 12 respectively opened on the lower surface and left side of the shielding cover 11, and an L-shaped heat conducting plate 13 fixedly installed on the inner wall of the assembly groove 12. A support plate 14 is fixedly installed on the left side of the cover plate 10, and the support plate 14 is inside the outer shell.

[0033] The materials of the shielding cover 11 and the cover plate 10 are both made of conductive plastic. Conductive plastic is a composite material made by adding conductive fillers such as metal powder, carbon fiber, etc. to a plastic matrix. These fillers are evenly distributed in the plastic matrix to form a conductive network. When electromagnetic waves encounter conductive plastic, due to the conductivity of the material surface, the electromagnetic waves will be reflected back. In addition to reflection, the conductive plastic can also absorb electromagnetic waves through its internal conductive network.

[0034] The L-shaped heat conducting plate 13 and the heat dissipating fins 22 are both made of copper plates. Copper has extremely high conductivity and is a very effective high-frequency magnetic field shielding material. Under high frequency conditions, copper can offset the incident electromagnetic waves by inducing reverse current, thereby achieving a good shielding effect.

[0035] The support plate 14 can be used to place the device. After the device is placed inside the shell, the shielding cover 11 and cover 10 made of conductive plastic, and the L-shaped heat conducting plate 13 made of copper plate can be used to shield external electromagnetic waves.

[0036] See Figure 2 、 Figure 4 and Figure 7 The heat dissipation structure includes an L-shaped heat dissipation cover 20, a heat dissipation fan 21 fixedly mounted on the upper surface of the L-shaped heat dissipation cover 20, heat dissipation fins 22 fixedly mounted on the surface of the L-shaped heat conducting plate 13, and an air inlet 23 opened on the right side of the L-shaped heat dissipation cover 20. The inner wall of the L-shaped heat dissipation cover 20 and the surface of the L-shaped heat conducting plate 13 are both provided with arc-shaped guide grooves.

[0037] When the device generates heat during operation, the heat in the casing will be transferred to the heat dissipation fins 22 through the L-shaped heat conduction plate 13. Then, the heat dissipation fan 21 is driven to allow the air flow to enter the interior of the L-shaped heat dissipation cover 20 along the air inlet 23 and be discharged from the exhaust port of the heat dissipation fan 21. In this way, the high-speed air flow can be used to pass through the heat dissipation fins 22 to dissipate the heat, and then the interior of the isolation cover body can be cooled.

[0038] See Figure 3 、 Figure 7 and Figure 8The assembly structure is arranged between the shell and the L-shaped heat dissipation cover 20, and is used to assemble the L-shaped heat dissipation cover 20 and the shell as a whole. The assembly structure includes mounting grooves opened on the front and back of the shielding cover 11, a limit pin 30 slidably installed on the inner wall of the mounting groove, and a limit groove 31 opened on the surface of the L-shaped heat dissipation cover 20. The inner wall of the L-shaped heat dissipation cover 20 is adapted to the surface of the shell. The inner wall of the mounting groove is provided with a compression spring 32 that can drive the limit pin 30 to insert into the inner wall of the limit groove 31.

[0039] When the L-shaped heat dissipation cover 20 is installed on the shielding cover 11, the limit pin 30 will be inserted into the limit groove 31, so that the L-shaped heat dissipation cover 20 can be installed on the shielding cover 11, and pressing the limit pin 30 can drive the limit pin 30 to disengage from the limit groove 31, so that the L-shaped heat dissipation cover 20 can be removed from the surface of the shielding cover 11. At this time, the L-shaped heat conducting plate 13 and the heat dissipation fins 22 can be exposed, so that dust attached to the L-shaped heat conducting plate 13 and the heat dissipation fins 22 can be removed to prevent dust accumulation from affecting their heat dissipation.

[0040] Compared with the existing technology, the device uses the L-shaped heat conducting plate 13 and the heat dissipation fins 22 to transfer the heat inside the shielding cover 11 to the heat dissipation fins 22 and the L-shaped heat conducting plate 13, and then uses the heat dissipation fan 21 to drive the air flow to take away the heat on the heat dissipation fins 22 and the L-shaped heat conducting plate 13, thereby avoiding the need to open air flow holes on the surface of the isolation cover body for heat dissipation, causing electromagnetic waves to enter the isolation cover body, and effectively improving the performance of the device in shielding electromagnetic waves.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
