Description

Technical Field

[0001] The utility model relates to the field of screen line shielding and sealing, in particular to a shielding and sealing device for reinforcing computer screen lines. Background Art

[0002] Reinforced computers are widely used in various application scenarios and are one of the key devices for transmitting and processing important data information. Their electromagnetic compatibility performance is not only related to their own working stability, but also affects the normal operation of the entire application scenario and peripheral equipment. At the same time, reinforced computers need to be deployed in outdoor environments and must be able to adapt to various complex and harsh environments such as rain and salt spray.

[0003] At present, in the electromagnetic compatibility test and actual application of reinforced computers, it is found that the electromagnetic leakage of display screen cables is one of the important reasons for the electromagnetic compatibility failure of reinforced computers.

At the line inlet at one end of the operating panel close to the screen shell body, a second conductive layer, a second fixed layer, and a cover plate covering the second conductive layer and the second fixed layer are provided to improve the sealing and electromagnetic shielding efficiency. After the screen line passes through the first sealing component for shielding and sealing from the screen shell body, it enters the operating panel through the line inlet, and the second sealing component is used to shield and seal the line inlet, replacing the traditional method of using conductive foam to fill the threading gap. While improving the sealing and electromagnetic shielding efficiency, it will not affect the screen line signal transmission.

[0037] See also Figure 1-Figure 10 , which is a schematic diagram of the structure of a shielding and sealing device for reinforcing a computer screen line provided in one embodiment of the utility model, wherein the shielding and sealing device for reinforcing a computer screen line is applied to a computer component, and the shielding and sealing device comprises a first sealing component and a second sealing component, wherein:

[0038] The computer component includes a screen housing 2, an operation panel 3 rotatably connected to the screen housing 2, and a screen cable 1 inserted between the screen housing 2 and the operation panel 3. The screen cable 1 passes through the inside of the screen housing 2 and then enters the inside of the operation panel 3. In order to improve the waterproof and anti-electromagnetic interference performance of the screen cable 1, the screen cable 1 is composed of a multi-core signal cable bare wire 11, the outer layer of the multi-core signal cable bare wire 11 is wrapped with an acetate tape 12, and the outer layer of the acetate tape 12 is wrapped with a conductive cloth tape 13. The conductive cloth tape 13 has excellent softness, excellent bending resistance, and superior anti-electromagnetic interference and other characteristics, so the screen cable 1 is a complete electromagnetic shielding cable. The front half of the screen cable 1 is fixed inside the screen housing 2, and the rear half of the screen cable 1 is fixed inside the operation panel 3.

[0039] In the screen housing 2, in order to ensure its sealing and shielding effects, a plurality of waterproof edges 21 are provided on the side of the screen housing 2 close to the operation panel 3, and mounting bosses 22 for mounting the first sealing assembly are provided on both sides of the waterproof edge port 26. A wiring groove 24 for arranging the screen line 1 is formed between the mounting bosses 22 of two adjacent waterproof edges 21. A first limiting female port 27 is provided between the mounting bosses 22 provided at the same waterproof edge port 26 for embedding the first sealing assembly. A plurality of in-line brackets 25 are also provided on the side of the screen housing 2 close to the operation panel 3 for use in a one-to-one correspondence with the first sealing assembly.

[0040] In order to cooperate with the screen housing 2 to improve the sealing and shielding effects, the first sealing component includes a first conductive layer 71, a pressure plate 5 and a first fixed layer 81 which are sequentially arranged on the screen line 1. The screen line 1 passes through the routing groove 24 and then passes through the line bracket 25. The line bracket 25 is arranged at the outer edge of the screen housing 2. The line bracket 25 is a semi-cylindrical bracket. The line bracket 25 and the rotating shaft between the screen housing 2 and the operation panel 3 are coaxially arranged to avoid wear of the screen line 1 when rotating.

[0041] The four corners of the pressing plate 5 are provided with first threaded holes 52. The pressing plate 5 is connected to the second threaded holes 23 on the mounting boss 22 of the adjacent waterproof edge 21 through the first fastener 61 through the first threaded holes 52. It is also provided with at least two first limiting male ports 53 used in conjunction with the first limiting female ports 27. When the pressing plate 5 is installed between the adjacent waterproof edges 21, the first limiting male ports 53 are embedded in the first limiting female ports 27, and the outer edge of the first limiting empty port is provided with a limiting bayonet 54 to face the waterproof edge port 26. A waterproof stopper 51 is also provided on the side of the pressing plate 5 away from the first limiting male ports 53 to overlap the waterproof edges 21 with open circular rings at both ends of the pressing plate 5 to improve the sealing performance of the screen housing 2.

[0042] The pressure plate 5 is installed on the screen housing 2, covering the screen line 1. The pressure plate 5 is placed above the wiring groove 24, wherein the first limit male port 53 is embedded in the first limit female port 27, and the waterproof edge 21 is clamped in the limit clamp port 54. The double limit design is limited to improve the surface alignment of the waterproof stop 51 and the waterproof edge 21, thereby forming a complete circle of waterproof components in the screen housing 2, and improving the shielding and sealing performance of the screen housing 2.

[0043] After the above assembly is completed, the first conductive layer 71 is potted on the inner side of the pressing plate 5, which fully fills the gap between the screen line 1, the screen housing 2 and the pressing plate 5, and plays an electromagnetic shielding role. The first fixing layer 81 is potted on the outer side of the pressing plate 5, which fully fills the gap between the screen line 1, the screen housing 2 and the pressing plate 5, and plays a sealing role.

[0044] Furthermore, a threading square hole 37 is provided at the wire inlet of the operation panel 3, a limiting strip 31 is provided on the periphery of the threading square hole 37, and a second limiting female opening 34 for use with the cover plate 4 is provided around the threading square hole 37 and the limiting strip 31. A first inlet bevel 32, a first outlet bevel 33, and a limiting slot 35 for the screen wire 1 to pass through are provided on the side of the threading square hole 37, and the first inlet bevel 32 and the first outlet bevel 33 are arranged opposite to each other. The outer edge of the first outlet bevel 33 is provided with a first outlet bevel fillet 39.

[0045] In order to cooperate with the threading square hole 37 to seal the screen cable 1 in the operation panel 3, the second sealing component includes a second conductive layer 72, a second fixed layer 82, and a cover plate 4 covering the second conductive layer 72 and the second fixed layer 82, which are arranged at the line inlet of the operation panel 3. The cover plate 4 includes a second inlet bevel 43, a second outlet bevel 42, and a wiring groove 48 arranged between the second inlet bevel 43 and the second outlet bevel 42. The edge of the cover plate 4 is also provided with a second limiting male opening 45, and a limiting block 46 extends between the wiring groove 48 and the second limiting male opening 45 toward one side of the operation panel 3. Connecting ears 41 are provided on both sides of the cover plate 4, and the second fastener 62 passes through the connecting ears 41 to connect to the threaded boss 38 arranged on the operation panel 3. The outer edge of the second outlet bevel 42 is provided with a second outlet bevel fillet 47.

[0046] When the cover plate 4 is connected to the fourth threaded hole 36 on the threaded boss 38 through the second fastener 62 through the third threaded hole 44 on the connecting ear 41, the second limiting male opening 45 is embedded in the second limiting female opening 34, and the limiting block 46 is embedded in the limiting slot 35. The double limiting design is used to improve the assembly accuracy of the cover plate 4.

[0047] The threading square hole 37 is set at the installation position of the operating panel 3 near the rotating shaft, and the cover plate 4 is installed directly below the threading square hole 37. The wiring groove 48 is aligned with the threading square hole 37. After the screen wire 1 vertically passes through the threading square hole 37, it first passes through the first entrance bevel 32, and then passes through the second entrance bevel 43. At this time, the screen wire 1 completes a 90° bend, and the outlet direction changes from vertical to horizontal, and then passes into the operating component along the first outlet bevel 33 and the second outlet bevel 42. The first outlet bevel radius 39 and the second outlet bevel radius 47 effectively prevent the screen wire 1 from being worn at the outlet.

[0048] After the above assembly is completed, a second fixing layer 82 is encapsulated at the wire inlet of the threading square hole 37 to fully fill the gaps at the wire inlets of the screen wire 1, the cover plate 4 and the operating panel 3, thereby playing a sealing role. A second conductive layer 72 is encapsulated at the wire outlet of the threading square hole 37 to fully fill the gaps at the wire outlet of the screen wire 1, the cover plate 4 and the operating panel 3, thereby playing an electromagnetic shielding role. The limit strip 31, the second limit male port 45 and the second limit female port 34 cooperate with each other to form a double stop to improve the sealing and electromagnetic shielding effectiveness, while effectively preventing the second conductive layer 72 and the second fixing layer 82 from overflowing. In this embodiment, the first conductive layer 71 and the second conductive layer 72 can be formed using conductive glue, and the first fixing layer 81 and the second fixing layer 82 can be formed using 704 glue.

[0049] In summary, according to a shielding and sealing device for reinforcing a computer screen line provided by the utility model, a first conductive layer, a pressure plate, and a first fixed layer are arranged on the screen line at one end of the screen shell body close to the operating panel to block the gaps between the waterproof edges, thereby achieving a sealing effect while also having an additional electromagnetic shielding effect. At the line inlet at one end of the operating panel close to the screen shell body, a second conductive layer, a second fixed layer, and a cover plate covering the second conductive layer and the second fixed layer are provided to improve the sealing and electromagnetic shielding efficiency. After the screen line passes through the first sealing component for shielding and sealing from the screen shell body, it enters the operating panel through the line inlet, and the second sealing component is used to shield and seal the line inlet, replacing the traditional method of using conductive foam to fill the threading gap. While improving the sealing and electromagnetic shielding efficiency, it will not affect the screen line signal transmission.
