Embodiment 5

[0055] This embodiment is an illustrative example of a dielectric material production method of the present disclosure.

[0056] (1) 4 metal wires are threaded into the extruder chamber of a rod extruder and then out of the extruder outlet of the rod extruder. The 4 metal wires are each coiled into a wire coil and are uncoiled during production. The rod extruder is a foam material rod extruder. In this embodiment, the material used is an EPE pearl cotton raw material. When the material extruded by the rod extruder forms a tube structure, the metal wires are pulled synchronously. The shape of the extruder outlet is designed accordingly such that the metal wires are evenly distributed in a tube wall without being in contact with each other so that a wired tube is obtained. In this embodiment, the diameter of the wired tube is 6 mm.

[0057] (2) Subsequently, the wired tube is cut into a tube structure with a height of 6 mm by a fixed-length cutter so that the dielectric material of the structure described in embodiment one is produced.

[0058] It is to be noted that the wired tube obtained in step (1) may be cut into the same length in a fixed-length manner and then step (2) is started, or the wired tube may be coiled integrally into a wire coil and then step (2) is started.
