[0002] As testing conditions increase, customers need to debug products under test in the laboratory and observe the test curves at any time as a basis for product rectification. The background noise of the display screen needs to meet relevant standards. Existing conventional displays on the market cannot meet the background noise requirements of the laboratory. Usually, the product under test is set up in a shielded room, and due to the limitations of data transmission settings, the display device is set up outside the shielded room. As a result, testers need to run back and forth between the product under test and the display device. At the same time, it is impossible to observe the product test curve on the display device in real time during the test, which will cause measurement errors and prevent further product optimization. Utility Model Content

[0003] This invention provides a monitoring device for rectification in EMC testing, which solves the problems in the background art, thereby enabling testers to observe the real-time test curve of the product under test on the display device in real time, so as to achieve the purpose of further product optimization.

[0026] In one embodiment, such as Figure 1-2 As shown, this utility model provides a rectification monitoring device for EMC testing, mainly including a housing 100 with a receiving cavity 101, and a first opening communicating with the receiving cavity 101; a shielding cover 200, rotatably mounted on the housing 100, which can be stored in the receiving cavity 101 of the housing; wherein, a transparent shielding glass 201 is provided on the shielding cover 200; and a display screen 203, which is detachably mounted inside the shielding cover 200 by screws or buckles, with the display interface of the display screen 203 corresponding to the position of the shielding glass 201, so that the experimental personnel can see the real-time data of the display screen 203 through the shielding glass 201.

[0027] In this embodiment, the shielding cover 200 is made of a 2mm thick stainless steel shell, which has a certain anti-interference capability, enabling the background noise requirements of the device to meet the relevant standards such as GJB, CISPR25, and CISPR16, demonstrating strong adaptability. In this embodiment, the material of the shielding cover 200 is not limited and can be other metal materials such as iron and alloys.

[0028] In one embodiment, in order to facilitate power supply to the enclosure 100 and data transmission via the data cable, a plurality of first through holes 102 are provided on the side wall of the enclosure 100. The plurality of first through holes 102 connect the outside world with the receiving cavity 101, thereby enabling external power cables or data cables to be connected to the inside of the enclosure 100.

[0029] In one embodiment, the receiving cavity 101 has a preset depth. When the shielding cover 200 is located inside the receiving cavity 101, one side of the shielding cover 200 is coplanar with the plane formed by the edge line of the first opening of the housing 100. In this embodiment, the side is the side parallel to the shielding glass 201. By setting the receiving cavity 101 to a preset depth, the shielding cover 200 can be kept horizontal when it is housed inside the receiving cavity 101. Since this device is used in a shielding room, a mounting groove is provided inside the shielding room, and the device is installed in the mounting groove on the ground 400. When the shielding cover 200 is housed inside the receiving cavity 101, the shielding cover 200 does not protrude from the ground 400 structure. Figure 5 As shown, this allows the device to not occupy space in the shielded room.

[0030] In one embodiment, to further enhance the protection of the shielding cover 200, a baffle 202 is provided on the shielding cover 200. The baffle 202 can completely cover one side of the shielding cover 200. The edge of the baffle 202 is set at a preset distance from the edge of the shielding cover 200. When the shielding cover 200 is located within the receiving cavity 101, the baffle 202 can block the first opening, thereby achieving all-round coverage of the shielding cover 200 and protecting it from damage by collisions with other objects or experimental personnel. In this embodiment, to facilitate the assembly of the display screen, an opening is provided on one side of the shielding cover 200 where the baffle 202 is fixed. The baffle 202 covers and blocks this opening, thus achieving protection of the shielding cover 200 while also enabling the detachable assembly of the display screen 203.

[0031] In one embodiment, to fix the shielding cover 200 relative to the housing 100 at a certain angle during the experiment, a support column 300 is provided between the housing 100 and the shielding cover 200. When the shielding cover 200 rotates to a certain angle relative to the housing 100, it is supported by the support column 300, thereby fixing the relative position of the shielding cover 200. This facilitates the experimenter's work and allows for easy observation of real-time test data.

[0032] In one embodiment, such as Figure 3As shown, to reduce the operational steps when opening the shielding cover 200, the support column 300 includes a support column body 302 and a telescopic rod 301. The telescopic rod 301 is telescopically mounted on the support column body 302, and the support column body 302 is movably connected to the housing 100. One end of the telescopic rod 301 is movably connected to the shielding cover 200. An air spring structure connects the telescopic rod 301 and the support column body 302. When the shielding cover 200 is opened to a certain angle, the telescopic rod 301 can provide a certain supporting force to the shielding cover 200 without external force. Optionally, the positions of the two ends of the support column body 302 and the telescopic rod 301 can be interchanged to achieve the same supporting purpose.

[0033] Optionally, the support column 300 can also be hinged at one end to the shielding cover 200 or the box 100, and the other end abuts against the box 100 or the shielding cover 200 when supporting, so that the box 100, the shielding cover 200 and the support column 300 form a triangular support structure.

[0034] In one embodiment, such as Figure 2 and Figure 3 As shown, since the shielding cover 200 needs to be stored in the receiving cavity 101 when not in use, a handle 204 is provided on the shielding cover 200 to facilitate opening the shielding cover 200. Since the baffle 202 covers the edge of the shielding cover 200, a corresponding first clearance notch is provided on the shielding cover 200. The handle 204 is positioned corresponding to the first clearance notch, so that the handle 204 is exposed, making it convenient for the experimental personnel to open and close the shielding cover 200.

[0035] In one embodiment, to facilitate data transmission between the display screen 203 and the outside world, multiple data interfaces 205 are provided on the shielding cover 200. These multiple data interfaces 205 are located on one side near the rotation point of the shielding cover 200 and are electrically connected to the display screen 203. Specifically, the data interfaces 205 include a VGA interface, a power switch for the display screen 203, and a power cord socket, etc.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
