AI Technical Summary
Existing technologies lack sufficient testing capabilities for the shielding effectiveness of trough-type cable trays, resulting in incomplete signal shielding and increased costs, and there is a lack of suitable test fixtures.
Design a shielding test fixture for cable trays, including a shielding motherboard, a locking assembly, conductive pads, and a bidirectional N-type video connector. By clamping with the locking assembly and setting the conductive pads, effective connection and electromagnetic shielding testing of the cable tray can be achieved. The depth of the tray structure is determined by combining the single-layer metal plate shielding effectiveness calculation formula to adapt to different size specifications.
It effectively solves the problem of insufficient testing capability for the shielding effectiveness of trough-type cable trays, provides a reasonable basis for the selection of trough-type cable trays, reduces engineering costs, and improves signal shielding effect.
