Abstract
A filler and a multicore cable includes a plurality of core portions, which includes a conductor, and a protective layer that surrounds the core portions, the filler being provided between the core portions and the protective layer of the multicore cable, the filler being characterized by including: frame portions including a first frame portion and a second frame portion, which are rotated by predetermined angles towards both sides about the center portion thereof and then incised; and a support portion provided between the frame portions so as to connect the frame portions to each other.
Claims14
A filler which is disposed between a core part and a protective layer of a multicore cable having a plurality of the core parts and the protective layer surrounding the plurality of core parts, wherein each core part comprises a conductor, an inner semiconducting layer, an insulating layer, an outer semiconducting layer, a metal sheath and a polymeric sheath,
- the filler comprising:
- a frame part including a first frame part and a second frame part which are symmetric to each other;
- a rotating part configured to connect the first frame part and the second frame part;
- a cut part dividing the frame part into the first frame part and the second frame part;
- optical unit accommodating part frames respectively formed at the first frame part and the second frame part;
- and
- an optical unit accommodating part configured to be opened or closed as the filler is rotated about the rotating part,
- wherein the filler is opened or closed by being rotated by a certain angle about the rotating part,
- wherein each of the first frame part and the second frame part comprises:
- an outer frame part formed in a circular arc shape;
- an inner frame part;
- and
- a support part configured to connect the outer frame part and the inner frame part, and
- wherein the cut part comprises:
- an upper cut part formed at the outer frame part;
- and
- a lower cut part formed at the inner frame part,
- wherein a length of the lower cut part is equal to or less than half an internal diameter of the optical unit accommodating part.
A multicore cable which includes a plurality of core parts, a protective layer surrounding the plurality of core parts and a filler disposed between the core part and the protective layer, wherein each the core part comprises a conductor, an inner semiconducting layer, an insulating layer, an outer semiconducting layer, a metal sheath and a polymeric sheath,
- the filler comprising:
- a frame part including a first frame part and a second frame part which are symmetric to each other;
- a rotating part configured to connect the first frame part and the second frame part;
- a cut part dividing the frame part into the first frame part and the second frame part;
- optical unit accommodating part frames respectively formed at the first frame part and the second frame part;
- and
- an optical unit accommodating part configured to be opened or closed as the filler is rotated about the rotating part,
- wherein the filler is opened or closed by being rotated by a certain angle about the rotating part,
- wherein each of the first frame part and the second frame part comprises:
- an outer frame part formed in a circular arc shape, and facing the protective layer;
- an inner frame part facing the core part;
- and
- a support part configured to connect the outer frame part and the inner frame part,
- wherein an optical unit is accommodated in the optical unit accommodating part, and an internal diameter of the optical unit accommodating part is greater than or equal to an external diameter of the optical unit,
- wherein the cut part comprises:
- an upper cut part formed at the outer frame part;
- and
- a lower cut part formed at the inner frame part, and
- wherein a length of the lower cut part is equal to or less than half an internal diameter of the optical unit accommodating part.
