For example, the shielding layer includes a plurality of cylindrical bars and a plurality of elliptical cylindrical bars, the plurality of cylindrical bars and the plurality of elliptical cylindrical bars are arranged at intervals, and the connecting structure includes a sleeved ring, a screwed ring and a clamping member. For example, the sheathing ring is fixed to one end of the second cable segment, the threaded ring is fixed to one end of the first cable segment, and the hoop member is clamped on the sheathing ring and screwed to the threaded ring, so that the core wire of the first cable segment is inserted into the sheathing ring and abuts against the end of the core wire of the second cable segment, thereby achieving the electrical connection between the first cable segment and the second cable segment.
