Description

Technical Field

[0001] This invention provides a shielding device for superconducting filter packaging, belonging to the field of superconducting filter packaging and shielding technology. Background Technology

[0002] Superconducting filters have extremely demanding operating environment requirements; external electromagnetic interference can severely affect their performance. To ensure stable and efficient operation, superconducting filters must be equipped with specialized shielding devices. The main function of the shielding device is to block the intrusion of external electromagnetic signals, creating a relatively pure electromagnetic environment for the superconducting filter, while preventing electromagnetic signal leakage generated by the filter itself from interfering with surrounding equipment. To enhance shielding effectiveness, some superconducting filters employ a double-shell design. After electromagnetic signals pass through the outer shell, the inner shell not only provides further shielding and attenuation but also compensates for the risk of leakage due to poor connection between the outer and inner shells.

[0003] Currently, existing shielding devices for superconducting filter packaging on the market are often assembled from multiple components. During installation and disassembly, various tools are required, and a significant amount of time and effort is spent to connect and secure each component. The two most important aspects are securing the filter and sealing the shielding device after packaging. Especially for packaging devices with two shielding shells, not only is it necessary to seal and secure the outer shell, but also the inner shell, making installation and disassembly cumbersome and detrimental to filter maintenance. To address these issues, a new type of shielding device for superconducting filter packaging is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that the filter packaging shielding device with inner and outer double shielding shells is difficult to disassemble and install, which is not conducive to filter maintenance.

[0005] To address the aforementioned problems, this invention proposes the following technical solution: a shielding device for encapsulating a superconducting filter, comprising an outer shell and an inner shell; the outer shell has an open top and an end cap that can close the upper part of the outer shell; the inner shell is located inside the outer shell and has an open bottom, with a support plate fixedly installed inside the outer shell to close the lower opening of the inner shell; a positioning groove is formed on the upper surface of the support plate, and the filter located inside the inner shell is placed in the positioning groove; a mounting plate is fixedly connected to the side wall of the filter, and a mounting hole is formed on the mounting plate; the end cap presses against the inner shell; a threaded hole corresponding to the mounting hole is formed at the bottom of the positioning groove, and the end cap is fixedly connected to the support plate through a screw and the threaded hole; the screw slides through the mounting hole, and a pressure block that presses against the mounting plate is fixedly sleeved on the shank of the screw.

[0006] As an improvement, the mounting plate, threaded hole, and screw are provided in two corresponding sets, and the threaded end on the screw body is located below the mounting plate.

[0007] As an improvement, the inner shell is provided with a second through hole for the screw to pass through, and the end cap is provided with a first through hole for the screw to pass through; the pressure block is cylindrical, and the diameters of the second through hole and the first through hole are both larger than the diameter of the pressure block.

[0008] As an improvement, the support plate has an installation groove, the lower end of the inner shell is inserted into the installation groove, and a sealing gasket is provided at the position where the inner shell and the installation groove are inserted.

[0009] As an improvement, a sealing groove is provided at the upper end of the outer shell, a sealing block fixedly connected to the bottom of the end cover is inserted into the sealing groove, and a sealing gasket is provided at the position where the sealing block and the sealing groove are interlocked.

[0010] As an improvement, both the outer shell and the inner shell have through holes on their rear sides that correspond to the wiring terminals of the filter.

[0011] The beneficial effects of this utility model are:

[0012] 1. The outer shell has an open top structure, and the upper end of the outer shell is provided with an end cap that can close the upper end of the outer shell; the inner shell has an open bottom structure, and the outer shell is fixedly provided with a support plate that can close the lower opening of the inner shell; by setting two shells, the shielding effect of the overall encapsulation shielding device can be increased.

[0013] 2. The end cap presses onto the inner housing. When the end cap is connected to the outer housing, it also limits the movement of the inner housing. Simultaneously, the end cap is fixedly connected to the support plate via a screw and threaded hole. The screw slides through the mounting hole, and a pressure block is fixedly fitted onto the screw shaft, pressing against the mounting plate. By setting a set of screws, not only can the end cap and outer housing be fixedly connected, but the inner housing can also be fixed, while the filter is fixed to the support plate. This allows for simultaneous and rapid fixing of the outer housing, inner housing, and filter, as well as quick disassembly, facilitating filter maintenance. Attached Figure Description
