Abstract

The invention relates to a shielding switching device for a large cable, which comprises a horizontal shielding shell and a vertical shielding shell, one end of the horizontal shielding shell is connected with the top end of the vertical shielding shell to form an L shape, and the horizontal shielding shell and the vertical shielding shell are communicated with each other at the connecting position; the horizontal insulator is arranged in the horizontal shielding shell in a sleeving manner, and a plurality of horizontal grooves are formed in the horizontal insulator in parallel; the vertical insulator is sleeved in the vertical insulation shell, a plurality of vertical grooves are formed in the vertical insulator side by side, each horizontal groove corresponds to one vertical groove, the corresponding horizontal groove and vertical groove are connected at the end part, and a cable lapping port is formed at the joint. According to the shielding switching device for the large cable, large-angle turning of the large-diameter cable in a limited space can be achieved, shielding can be effectively carried out, and crosstalk coupling of electromagnetic signals is avoided.
