Abstract
A cable reel using a tape-shaped cable including a high-strength conductor having a tensile strength of 500 to 1500 N/mm.sup.2, an elongation percentage of 0.5 to 50% and a spring limitation value of 400 to 2000 N/mm.sup.2. Accordingly, in such a cable reel, weight as well as cost of the whole or parts in a cable reel can be reduced.
Claims16
A cable reel comprising:
- a housing including an inner cylinder having an inner cylinder hole and an outer cylinder having an outer cylinder hole;
- and
- a tape-shaped cable which is spirally housed in said housing, both end portions of said tape-shaped cable being introduced to outside of said housing through said inner cylinder hole and said outer cylinder hole, respectively;
- wherein said tape-shaped cable includes at least one high-strength conductor having a tensile strength of from 500 to 1500 N/mm.sup.2, an elongation percentage of 0.5 to 50% and a spring limitation value of 400 to 2000 N/mm.sup.2 ;
- and
- wherein said cable reel absorbs relative rotation between an external member that generates an external force and said inner cylinder by tightening and loosening of windings of said tape-shaped cable.
