Abstract

An electronic device comprises a plate body provided with a perforated hole and an anti-backflow assembly accommodated and fixedly arranged in the perforated hole. The anti-backflow assembly comprises at least one anti-backflow member. The anti-backflow member comprises a base fixedly arranged in the inner side of the perforated hole and a plurality of wind-blocking portions which are made of soft materials, are used for shielding the perforated hole, and are arranged on the base. The wind-blocking portions can deform to allow a cable or a circuit board to pass through. After passing of the cable or the circuit board, the wind-blocking portions can recover elasticity to fully shield the perforated hole, so that backflow of the wind flow in the electronic device can be prevented.

Description

electronic device

technical field

The invention relates to an electronic device.

Background technique

Electronic devices, such as servers, usually have holes reserved in casings for routing or hot-swapping electronic components (such as circuit boards). After the assembly of wires or the insertion and removal of electronic components is completed, the reserved holes will cause backflow of airflow, greatly affecting the heat dissipation performance of the electronic device.

Contents of the invention

In view of the above, it is necessary to provide an electronic device that can prevent the backflow of the airflow from the reserved hole.

An electronic device, comprising a plate body provided with a perforation and a backflow prevention component accommodated and fixed in the perforation, the backflow prevention component includes at least one backflow prevention component, and the backflow prevention component includes a base fixed inside the perforation And a number of windshield parts made of soft material that are arranged on the base to cover the perforation.

Compared with the prior art, several windshields made of soft materials that can block the wind flow are installed in the perforations of the board body of the electronic device, and these windshields can be deformed to allow cables or circuit boards to pass through. After the cable or the circuit board passes through, these windshield parts can elastically recover to completely cover the perforation, thereby preventing the wind flow inside the electronic device from flowing back.

The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Detailed ways

Referring to FIGS. 1 to 4 , a preferred embodiment of the electronic device of the present invention includes a case 10 and a backflow prevention component 20 .

Several electronic components and a board 12 are installed in the casing 10 . The board body 12 defines a square through hole 121 .

The backflow prevention assembly 20 includes two backflow prevention components 23 . Each anti-reflux member 23 includes a rectangular base 231 made of soft material, such as heat-resistant rubber, and a number of long hairs made of soft material, such as heat-resistant rubber, on the top surface of the base 231. , a strip-shaped or sheet-shaped windshield portion 233 .

When assembling, the bottom surfaces of the bases 231 of the two anti-reflux components 23 are pasted on the two opposite side walls of the through hole 121 of the plate body 12 with heat-resistant double-sided adhesive tape or other adhesives. At this time, the ends of the windshield portions 233 of the two backflow preventing elements 23 (ie, the ends away from the base 231 ) abut or are adjacent to each other.

Since these windshields 233 are made of soft materials, when cables or small electronic components (such as circuit boards) in the electronic device are to pass through the through holes 121 of the board body 12, these windshields 233 respectively The sides flex to allow cables or boards to pass through without damaging the board. After the cables or circuit boards pass through, the windshields 233 recover elastically to completely cover the through holes 121 , so as to prevent the wind from flowing back.

In other embodiments, in order to more firmly fix the base 231 of the anti-reflux member 23, the width of the base 231 can be made larger than the thickness of the plate body 12, so that the middle part of the base 231 is pasted on the corresponding side wall of the perforation 121, and the two sides of the base 231 The side bends and is pasted on both sides of the board body 12 respectively.

In other embodiments, the anti-backflow assembly 20 may only include a backflow prevention member 23, only need to increase the length of the windshield part 233 of the backflow prevention member 23, so that the end of the windshield part 233 abuts or is adjacent to the through hole 121 On the side wall opposite to the base 231 , it is sufficient that the windshields 233 completely cover the through hole 121 .

Please refer to FIG. 5 , in other embodiments, for a plate body 31 provided with a circular through hole 312 in the electronic device, a circular anti-reflux member 41 may be used. The anti-reflux member 41 includes an annular base 411 made of soft material, such as heat-resistant rubber, and a long-haired, strip-shaped soft material, such as heat-resistant rubber, located on the inside of the base 411. Or several sets of windshields 413 in sheet form. Each group of windshield parts 233 is arranged in a fan shape, and the ends (ie, the ends away from the base 411 ) of every two groups of adjacent windshield parts 413 abut or are adjacent to each other. The outer side of the base 411 is pasted on the inner wall of the through hole 312 of the plate body 31 by heat-resistant double-sided adhesive tape or other glue. When the cables or small circuit boards in the electronic device are to pass through the through holes 312, the windshields 413 are respectively bent and deformed to different sides to allow the cables or circuit boards to pass through without damaging the circuit boards. After the cables or circuit boards pass through, the windshields 413 elastically recover to completely cover the through holes 312 , so as to prevent the wind flow inside the electronic device from flowing back.
