Embodiment Construction

[0013] see Figure 1 to Figure 3 , the anechoic chamber 100 of the present invention includes a box 10 , a support frame 30 and a receiver 50 . The receiver 50 is provided with an antenna 52 for receiving signals.

[0014] An accommodating space 15 is formed inside the box body 10 , and a wave-absorbing material 17 is disposed on the inner surface of the box body 10 . A side wall 14 of the box body 10 defines a square opening 16 . The left and right sidewalls of the opening 16 are respectively provided with elastic protrusions 142 with arc-shaped cross-sections. A central portion of the top wall and the bottom wall of the opening 16 respectively defines a shaft hole 144 opposite to each other.

[0015] The supporting frame 30 includes a square shielding plate 32 and two supporting plates 34 vertically disposed on inner and outer walls of the shielding plate 32 . Each support plate 34 is semicircular and has a mounting platform 345 capable of carrying a DUT 500 . The inner...

Abstract

An electromagnetic anechoic chamber includes an anechoic chamber and a supporting bracket. A sidewall of the anechoic chamber defines an opening. The supporting bracket includes a shielding piece rotatably mounted to the anechoic chamber to cover the opening, and two test benches respectively fixed to two opposite side surfaces of the shielding piece. When an item of information technology equipment (ITE) is assembled to one of the test benches and the supporting bracket is rotated to make the shielding piece cover the opening and the ITE enter the anechoic chamber, the other test bench is exposed out of the chamber and another piece of ITE can be assembled thereon.

Description

technical field [0001] The invention relates to the field of electromagnetic testing, in particular to an anechoic chamber. Background technique [0002] General electromagnetic compatibility (Electromagnetic Compatibility, EMC) tests need to use an anechoic chamber as a test site for testing. The existing anechoic chamber generally includes an anechoic chamber, a test turntable installed in the anechoic chamber and a receiver provided with an antenna. The test process of the current anechoic chamber: install the first DUT on the test turntable, turn on the first DUT and debug it; test the first DUT, and the antenna receives the first DUT The working signal generated by one DUT is converted into an electrical signal for the receiver to read, and the working signal strength radiated by the first DUT to space is detected; the first DUT is evacuated from the anechoic chamber; Then install the second test object on the test turntable, debug, test, and evacuate; then test the t...
