Technical Field
[0001] This utility model relates to the field of radio frequency testing equipment technology, and in particular to an integrated radio frequency shielding tester with a display screen. Background Technology
[0002] Electromagnetic shielding boxes are shielding bodies of various shapes, such as shells, plates, and sleeves, made of conductive or magnetic materials. They are metal bodies that confine electromagnetic energy within a certain space to suppress radiation interference and process conduction and radiation to provide an interference-free testing environment for the wireless communication equipment under test.
[0003] The publication number CN119335231A provides an electromagnetic shielding box for testing radio frequency chips, which belongs to the field of electromagnetic shielding boxes. The present invention includes a shielded enclosure with a support plate inside. A hollow solenoid is rotatably connected to the right side of the enclosure via a pivot, the right end of which extends into the interior of the enclosure and is threadedly connected to a threaded sleeve on its outer wall. A fixing block is fixedly connected to the front right side of the enclosure, and a concave part is rotatably connected to the outer wall of the fixing block via a pivot. An inclined abutment piece is fixedly connected to the rear surface of the concave part. The support plate is used to place the RF chip and can slide along the inside of the shielded enclosure, together forming a protective shell for the RF chip. It is inserted into the inner side of the locking seat through a connector box on the cover, and can be locked into the locking slot by the locking block, so that the cover can cover the shielded enclosure. Although this technical solution can achieve a closed shielding effect for the RF chip, facilitating subsequent testing, it does not have a display function and requires an external display device, making it inconvenient for users to directly observe test data. Therefore, an integrated RF shielding test machine with a display screen is provided to solve the above problems. Utility Model Content
