Abstract

The invention belongs to the field of cables, and particularly relates to a layer-stranded optical cable with heart-shaped units, which is provided with an outer protective layer and at least three loose tubes, and is characterized in that each loose tube is composed of two loose tube main bodies, a connecting rib is arranged between the loose tube main bodies, the connecting rib is V-shaped, a loose tube protective layer is further arranged outside the loose tube, the loose tube protection layer body is in an open heart shape, an open groove is formed in the top of the loose tube protection layer body, the loose tube protection layer body at the two ends of the open groove is connected with two compression components, the width of the open groove is smaller than that of the loose tube, and limiting components are arranged on the inner wall of the outer protection layer body and clamped between the two adjacent loose tube protection layers. A center stabilizing component is arranged at the convergence position of the heart-shaped bottoms of all the loose tube protection layers. The loose tube has the advantages of being simple in structure, high in compression resistance and tensile property, not prone to deformation of the loose tube body, good in heat dissipation performance and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a layer twisted optical cable with a heart-shaped unit. Background technique [0002] With the large-scale promotion of domestic 5G construction, the demand for optical cables is increasing, and with a large number of layings every year, pipeline resources are becoming less and less. Therefore, it is necessary to replace multiple laying of small cores by laying optical cables with large cores. Optical cables to reduce the waste of pipeline resources. [0003] In the prior art, such as CN110824649A discloses a new type of pressure-resistant optical cable, which has a strengthening member, a loose tube and an outer sheath, and at least one optical communication component is arranged in the loose tube, which is characterized in that the loose tube and A compression belt is also provided between the outer sheaths, and the compression belt is composed of a compression belt base belt, at least o...
