Abstract

In a method for manufacturing a cable, a filling step S5 of filling a tube hole of a socket main body which is formed in a tubular shape and in which first end portions of wire rods are disposed with a mixture obtained by mixing a thermosetting resin into a preliminary mixture obtained by mixing ceramic particles and fly ash in advance is carried out.

First claim

What is claimed is:

1. A method for manufacturing a cable, comprising:
a filling step of filling a tube hole of a socket main body which is formed in a tubular shape and in which first end portions of wire rods are disposed with a mixture obtained by mixing a thermosetting resin into a preliminary mixture obtained by mixing ceramic particles and fly ash in advance,
wherein the ceramic particles are formed in non-fibrous particles.

2. The method for manufacturing a cable according to claim 1 , further comprising, before the filling step:
a wire rod insertion step of respectively inserting first end portions of the wire rods into the tube hole of the socket main body and through holes formed in a fixation plate; and
a locking step of locking expanded diameter portions provided at first end portions of the wire rods to edge portions of the through holes in the fixation plate and separating first end portions of the wire rods from an inner circumferential surface of the tube hole.

3. The method for manufacturing a cable according to claim 1 ,
wherein, after the filling step,
the mixture is hardened so as to produce a filling material, and
a second filling material having an elastic modulus that is smaller than an elastic modulus of the filling material is provided on the second end portion side of the wire rods compared with the filling material.

4. The method for manufacturing a cable according to claim 1 , wherein the thermosetting resin is an epoxy resin.

5. The method for manufacturing a cable according to claim 1 , wherein a ratio of a mass of the ceramic particles to a mass of the fly ash, which are mixed together in the filling step, is 7.0 or more.

6. The method for manufacturing a cable according to claim 1 , wherein a ratio of a sum of the mass of the fly ash and the mass of the ceramic particles to a mass of the thermosetting resin, which are mixed together in the filling step, is 5 or more.

7. A cable comprising:
a socket main body formed in a tubular shape;
wire rods having a first end portion disposed in a tube hole of the socket main body; and
a filling material which is loaded into the tube hole of the socket main body and is hardened after being mixed with ceramic particles, fly ash, and a thermosetting resin,
wherein the ceramic particles are formed in non-fibrous particles.

8. The method for manufacturing a cable according to claim 1 , wherein a ratio of a mass of the ceramic particles to a mass of the fly ash, which are mixed together in the filling step, is 7.2 or more.
