Embodiment Construction
[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustr...

The invention relates to an antenna calibration network device comprising a metal baseplate, a calibration circuit and a shielding cover. The shielding cover comprises a cover made of metal, a cover plate which is flexibly connected with the cover through flexible connection components and elastic members. The cover is provided with a debugging window. When debugging requires to be performed, thecover plate can be operated to move relative to the cover until the cover plate is switched to the open state. Then the debugging window is opened and the calibration circuit in the shielding cavity can be debugged through the debugging window. After completion of debugging, the cover plate is operated to be switched to be closed state, the cover plate closes the debugging window and the shieldingcover realizes the effect of electrostatic shielding. Besides, the cover plate can be locked on the cover by the locking members so that the cover plate can closely contact the cover and the shielding effect of the shielding cavity is ensured not to be influenced. Therefore, integral disassembling and assembling of the shielding cover do not need to be performed in case of debugging of the antenna calibration network device so that debugging of the antenna calibration network device is more convenient.
Description
Technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an antenna calibration network device and its shielding cover. Background technique [0002] In recent years, mobile communication technology has continued to develop, and the number of users has also shown a rapid growth trend. 5G antennas have become an important development trend. As a component of the 5G antenna system, the coupling calibration network plays a key role in communicating system equipment and antennas. [0003] Most of the previous calibration networks used open or semi-open structures, which have the advantages of simpler structure and convenient installation, but their anti-interference ability is poor and are susceptible to external shocks and electromagnetic interference. Therefore, a closed calibration network structure is designed to solve the problem of external interference. [0004] During the use of the calibration network, parameters suc...
