Description

Technical Field

[0001] This utility model specifically relates to a splicing module and module connection structure for the shell of an anechoic chamber shielding room, belonging to the technical field of anechoic chamber shielding room shells. Background Technology

[0002] Anechoic chambers provide precise testing spaces for emerging industries such as 6G communications and intelligent vehicles, and also serve as a guarantee for the research and development of national defense equipment. Shielded chambers use metal structures to isolate electromagnetic interference, building a solid barrier for information security and stable equipment operation. The shielding shell, as the core structure of the anechoic chamber, is made of highly conductive metal materials and has multiple key functions: it effectively blocks external electromagnetic interference and prevents internal energy leakage by reflecting and absorbing electromagnetic waves, creating a pure testing environment; it provides stable physical support for absorbing materials, testing equipment, and auxiliary systems, forming the basic framework of the anechoic chamber; its precise dimensions define the testing space, meeting the requirements of far-field and quiet zone testing. In existing technologies, the shielding shells of large anechoic chambers are generally assembled by welding. Welded anechoic chambers have advantages such as high reliability, resistance to deformation, and stable and reliable electrical parameters. However, the on-site construction of the shielding shell of an anechoic chamber is limited by the conditions of the construction site and equipment, resulting in a long processing cycle and failing to meet high-standard processing requirements. At the same time, large anechoic chambers such as those for far-field and compact fields pose significant safety hazards during construction. Utility Model Content

The grid body is fixed to the back of the panel, and the ends of the grid are fixed to the frame. The skeleton serves as a support unit for the panel and the frame, enabling support for the back of the panel and the inner surface of the frame.

[0008] Furthermore, the three-way connector is integrally formed with a right-angled triangular plate that fits into the corner of the frame; the corner of the frame and the right-angled triangular plate are fixed by full welding.

[0009] Compared with existing technologies, the anechoic chamber shielding shell splicing module and module connection structure of this utility model adopt modular processing and production of the shielding shell in the factory, which improves the processing efficiency of the anechoic chamber shell and significantly shortens the production cycle. In the installation stage, the standardized splicing modules can reduce the complexity of on-site construction, which not only effectively reduces installation time, but also significantly improves construction safety and system reliability, and can reduce unnecessary material waste. Each splicing module is connected by modular screws and reinforced by welding, which improves the overall flatness of the shell and effectively enhances the shielding performance and stability of use.
