AI Technical Summary
The lack of proper electrical contact between the two ends of the shielding tube and the cavity leads to microwave leakage, resulting in a leakage wave phenomenon.
The conductive components, with their two ends abutting against the side walls of the cavity, are used. The elastic components and fixing devices ensure good contact and increase the contact area. The stability of the electrical contact is achieved by using flexible conductive components and edge limiting structures.
It effectively reduces the risk of microwaves being vented outside the cavity by the shielding tube, improves the reliability of electrical contact and ease of installation, and solves the problem of microwave leakage.
