Embodiment 1

[0025] The antenna supports 36 are provided in four groups, and the antenna supports are evenly distributed on the antenna panel 31; each group of antenna supports is provided with an antenna module 7 correspondingly, and the antenna modules 7 are installed symmetrically with respect to the antenna panel. Symmetrical installation is convenient for adjusting the installation position of the antenna module.

[0026] The antenna bracket is an arc-shaped bracket, and the antenna module mounting structure 32 is a mounting hole. It should be noted that the antenna module mounting structure 32 is not limited to mounting holes and other forms, such as buckles, etc.; any mounting structure capable of fixing the antenna module at any position on the antenna support belongs to the protection scope of the present invention.

[0027] The connection between the antenna module 7 and the product under test on the carrier board assembly constitutes a first connection, and the connection between the...

Embodiment 2

[0031] The test cavity 10 is provided with a door body 50, and the joint between the door body and the box body is provided with a concave-convex sealing structure. The concave-convex sealing structure includes a convex door structure, a concave box structure, and a sealing material. The convex structure of the door matches the concave structure of the box, and the convex structure of the door matches the concave structure of the box. Shielding material 8 is provided between. In addition, the edge 52 of the convex structure of the door and the edge 11 of the concave structure of the box are both provided with a D-shaped shielding material 53 / 12, which further reduces the leakage at the junction of the door and the box.

[0032] Among them, the door and the box body are matched in a 110° way, and the shielding materials in three directions (shielding material 8, D-shaped shielding material 53 / 12) are pressed together, and the leakage at the junction of the door and the box is the ...

Embodiment 3

[0036] The side wall of the box body is provided with a slidable component in the vertical direction; the antenna support is a telescopic support, one end of the telescopic support is hinged to the antenna panel, and the other end of the telescopic support is hinged to the antenna panel The slidable component. This design can change the tilt angle of the antenna support well to meet different test requirements.

Abstract

The invention discloses a 5G test shielding box, which comprises a box body. The inner wall of the box body is provided with an wave absorbing layer. The box body comprises a test cavity and a controldriving cavity between which a shielding isolation unit is disposed. An antenna unit and a carrier plate assembly are disposed in the test cavity. The antenna unit includes an antenna panel, a plurality of antenna brackets, and a plurality of antenna modules, wherein the antenna panel is fixed to the center of the top of the box body; a central antenna module is fixed to the antenna panel; one end of each antenna bracket is fixed on the antenna panel; the other end of each antenna bracket is fixed on the sidewall of the box body; each antenna bracket is provided with a plurality of antenna module mounting structures; the antenna modules are detachably fixed to the antenna module mounting structures. Compared with the prior art, the shielding box of the invention can test fifth-generationmobile communication products, and has a good shielding effect and high test precision.

Description

Technical field [0001] The invention relates to the technical field of shielding boxes, in particular to a 5G test shielding box. Background technique [0002] The fifth-generation communication technology has higher reliability and lower latency, and can meet the specific needs of intelligent manufacturing, autonomous driving and other industry applications, broaden the development space of integrated industries, and support economic and social innovation and development. At the same time, the communication frequency band of the fifth-generation mobile communication products is 700MHz~60GHz, and the range of products required to be tested is wider and higher. Therefore, the fifth-generation communication products are tested more strictly. [0003] In the prior art, the test frequency of the shielding box and the antenna can generally only reach 6 GHz, which cannot be compatible with higher test frequencies, and cannot guarantee the accurate test of the fifth-generation mobile comm...
