Abstract

A terminal treatment method for a coaxial cable including a core member having an inner conductor covered with an insulator, an outer conductor provided around the core member and formed of a plurality of wires, and a sheath covering an outer circumference of the outer conductor, includes exposing the outer conductor by removing the sheath on an end portion of the outer conductor, and widening a terminal of the outer conductor away from the core member by compressing a terminal-near portion of the exposed outer conductor from an outer circumferential side of the coaxial cable to deform the terminal-near portion of the exposed outer conductor.

First claim

What is claimed is:

1. A terminal treatment method for a coaxial cable including a core member having an inner conductor covered with an insulator, an outer conductor provided around the core member and formed of a plurality of wires, and a sheath covering an outer circumference of the outer conductor, the terminal treatment method comprising:
exposing the outer conductor by removing the sheath on an end portion of the outer conductor;
widening a terminal end of the outer conductor away from the core member by compressing a portion near the terminal end of the exposed outer conductor from an outer circumferential side of the coaxial cable to deform the terminal-near portion of the exposed outer conductor;
mounting a core piece onto a terminal end of the core member to separate the widened outer conductor from the core member;
loosening the plurality of wires away from the core member, exposing the core member; and
extracting the exposed core member from between the loosened plurality of wires.

2. The terminal treatment method of claim 1 , wherein the plurality of wires are wound around the core member in a spiral pattern.

3. The terminal treatment method of claim 2 , wherein the loosening comprises:
pressing the widened terminal end of the outer conductor against the core piece; and
rotating the pressed terminal end of the outer conductor in a direction opposite a winding direction of the spiral pattern to loosen the plurality of wires away from the core member, exposing the core member.

4. The terminal treatment method of claim 3 , further comprising separating the loosened plurality of wires to form two gaps among the outer conductor to expose the core member,
wherein extracting comprises extracting the exposed core member from between the loosened plurality of wires.

5. The terminal treatment method of claim 4 , further comprising re-winding, after the extracting, the plurality of wires by rotating the pressed terminal end of the outer conductor.

6. The terminal treatment method of claim 5 , further comprising converging, before the re-winding, the loosened plurality of wires around an axis of the coaxial cable.

7. The terminal treatment method of claim 6 , further comprising cutting and removing, after the re-winding, the pressed terminal end of the outer conductor.

8. The terminal treatment method of claim 5 , further comprising cutting and removing, after the re-winding, the pressed terminal end of the outer conductor.

9. The terminal treatment method of claim 3 , further comprising re-winding, after the extracting, the plurality of wires by rotating the pressed terminal end of the outer conductor.

10. The terminal treatment method of claim 9 , further comprising converging, before the re-winding, the loosened plurality of wires around an axis of the coaxial cable.

11. The terminal treatment method of claim 10 , further comprising cutting and removing, after the re-winding, the pressed terminal end of the outer conductor.

12. The terminal treatment method of claim 9 , further comprising cutting and removing, after the re-winding, the pressed terminal end of the outer conductor.

13. The terminal treatment method of claim 12 , wherein the core piece is substantially cylindrical.

14. The terminal treatment method of claim 1 , wherein the extracting step comprises:
inserting a jig into a gap formed between the plurality of wires by the loosening step, and
pushing out the core member.
