In one embodiment, the insulating layer 210 is a PTFE tape. The PTFE tape has the characteristics of low relative density, low dielectric loss, small influence by temperature and signal frequency changes, and stable dielectric constant, and therefore, the use of the PTFE tape can improve flexibility and electrical performance of the VR high-speed connection line 10.
In one embodiment, the braid 220 is a metal braid for shielding electromagnetic interference, and specifically, the braid is woven by using a plurality of metal wires, and the metal wires may be made of copper wires, tinned copper wires, aluminum-magnesium alloy wires, and the like.
