Shielding dark box

Abstract

The invention discloses a shielding dark box. The shielding dark box comprises a box body made from a conductive material, wherein the bottom of the box body extends downwardly in an inclined manner, and a leakage opening is formed in the lowest position of the bottom; a leakage opening cover for sealing the leakage opening is arranged on the leakage opening; a wire-inlet slot opening and a wire-outlet slot opening are formed in the two opposite side walls of the box body respectively; a wire-coiling opening is also formed in the side wall, close to the center position, of the wire-outlet slot opening; and the wire-coiling opening cover for sealing the wire-coiling opening is arranged on the wire-coiling opening. A cable enters the box body from the wire-inlet slot opening; the cable is coiled for at least one circle in the box body and then is led out of the wire-outlet slot opening, so that the inlet-outlet cable orthogonality can be ensured; after the cable is fully wired, red copper granules are poured into the box boy until the box body is filled fully; and in addition, the bottom of the box body extends downwardly in an inclined manner, so that the box body can be full of the red copper granules without gaps, and the purpose of no leakage of electromagnetic waves is realized.

Description

technical field [0001] The invention relates to a shielding dark box. Background technique [0002] With the rapid development of electronic technology, the electromagnetic environment is becoming more and more complex. Both military and civilian fields have put forward stricter requirements for the electromagnetic environment used by equipment. When the hardware-in-the-loop simulation test system is tested, the leakage of the electromagnetic signal of the equipment makes the test electromagnetic environment more complicated, which will not only affect the test process and the confidence of the test results, but also bring certain harm to the health of the test personnel. Therefore, the test is usually carried out in a shielded dark room. Testing wireless communication products such as antennas and radars and electronic products in a dark room can avoid clutter interference and improve the test accuracy and efficiency of the equipment under test. When the external cable is ...

Problems solved by technology

However, such shielding often has gaps or the incoming and outgoing cables are not orthogonal to cause electromagnetic wave leakage, which is not conducive to the performance requirements of high-performance shielded darkrooms.
