Problems solved by technology

Although the radio wave isolation anechoic chamber can effectively shield electromagnetic waves, it is usually fixed and inconvenient to use
In some cases (for example, the electronic device to be tested cannot or is inconvenient to be moved in a radio-isolated anechoic chamber), it is difficult to shield the electronic device from environmental noise (such as the frequency of mobile phone base stations), which makes the measurement results at this time distorted or even invalid
In addition, some measurement equipment itself will generate electromagnetic waves (such as USB, HDD read and write signals), so that even if the measurement is performed in a radio-isolated anechoic room, the measurement results still cannot accurately reflect the operation of the electronic device

Embodiment Construction

[0037] see figure 1 and figure 2 . According to one embodiment, a foldable electromagnetic shielding box 12 includes a plurality of plates, which include a foldable U-shaped structure 122 and two separable plates 124, and the two separable plates 124 can be detachably sealed and detachable. The two side openings 122a of the U-shaped structure 122 are folded to form an isolation space 12a. Wherein, the foldable ㄇ-shaped structure 122 comprises three connected boards (such as but not limited to hinged connection), through a plurality of foldable brackets 126 connected between the adjacent boards can make the foldable Glyph structure 122 expands and is ㄇ font (as figure 2 ) or folded (such as image 3 ). The detachable plate body 124 can be connected with the unfolded foldable U-shaped structure 122 through buckles, locks, snaps, and the like. In this way, the foldable U-shaped structure 122 can be folded and unfolded to form the isolation space 12a, and can be folded int...

Abstract

The invention provides a test system capable of shielding environmental noise, which utilizes a foldable electromagnetic shielding box to isolate devices which can generate electromagnetic interference on a to-be-tested object so as to suppress the influence of the devices on the measurement of the to-be-tested object. In one embodiment, the measuring device and the object to be measured are both arranged in the foldable electromagnetic shielding box so as to shield external electromagnetic waves. In another embodiment, the measuring equipment is arranged in the foldable electromagnetic shielding box, and the object to be measured is arranged outside the foldable electromagnetic shielding box so as to shield the electromagnetic waves generated by the measuring equipment. The foldable electromagnetic shielding box can be folded to facilitate storage or transportation.

Description

technical field [0001] The present invention relates to a testing system capable of shielding environmental noise, in particular to a testing system utilizing a foldable electromagnetic shielding box to shield environmental noise. Background technique [0002] The operation of some electronic devices may be affected by electromagnetic waves, and measurements performed on such electronic devices may also be affected by electromagnetic waves. Although the radio wave isolation anechoic chamber can effectively shield electromagnetic waves, it is usually fixed and inconvenient to use. In some cases (for example, the electronic device to be tested cannot or is inconvenient to be moved in a radio-isolated anechoic chamber), it is difficult to shield the electronic device from environmental noise (such as the frequency of mobile phone base stations), which makes the measurement results at this time distorted or even invalid . In addition, some measurement equipment itself will gen...
