Abstract
Since it is configured such that the gap between the pipe 20 and the electric wire 10 in the pipe 20 is filled with a filler 30 having a heat conductivity higher than that of air, the heat generated in the electric wire 10 is transferred to the filler 30, then from the filler 30 to the pipe 20, and is discharged from the outer periphery of the pipe 20 to the outside air. Since the filler 30 has a heat conductivity higher than that of air, the performance in discharging the heat generated in the electric wire 10 is superior compared with a case in which the filler 30 is not charged. Thus, heat dissipation in the shield conductor using a pipe is improved.
Claims21
-10. (canceled)
A shield conductor comprising:
- an electric wire including a conductor and an insulation coating;
- a metallic pipe, wherein said electric wire is positioned in the metallic pipe;
- and
- a filler located in a gap inside said pipe between said electric wire and said pipe, said filler having a heat conductivity higher than that of air.
A method of producing a shield conductor having a configuration comprising the steps of:
- inserting an electric wire into a metallic pipe such that a gap between the electric wire and the pipe is formed;
- providing a first end portion of said pipe having an injection opening and a second end portion of said pipe opened upwardly;
- and
- injecting a filler into said pipe from said injection opening, and concurrently releasing air in said pipe to the outside from the second end portion, wherein the filler has a heat conductivity higher that air.
A method of producing a shield conductor having a configuration comprising the steps of:
- inserting an electric wire into a metallic pipe such that a gap between the electric wire in the pipe and the pipe is formed;
- injecting a filler from one end portion of said pipe while suctioning air in said pipe to discharge it to the outside an end portion of said pipe, wherein the pipe is filled with a filler having a heat conductivity higher than that of air.
A method of producing a shield conductor having a configuration comprising the steps of:
- inserting an electric wire into a metallic pipe such that a gap between the electric wire in the pipe and the pipe is formed
- coating the electric wire with a sheath;
- coating the sheath with a filler, the filler having a heat conductivity higher than that of air;
- and
- filling the pipe with the filler;
- and
- inserting the wire into said pipe.
