Abstract

The invention belongs to the field of cables, and, in particular, relates to a nested cable. The cable is composed of a plurality of electric units and an outer protective layer, and is characterizedin that the outer protective layer is composed of two first protective layers and two second protective layers, each first protective layer is composed of a first protective layer main body, two firstblocking parts and two second blocking parts, and each first protective layer body is in an open semi-arc shape; each second protective layer is composed of two third blocking parts and a second protective layer main body, the two third blocking parts are arc-shaped, and the two third blocking parts and the second protective layer main body form a semicircle with an opening; and the first protective layers and the second protective layers are nested with each other to form four first accommodating cavities, and the at least one electric unit is arranged in each first accommodating cavity. Theinvention also discloses the nested optical cable. The problems that the outer protective layer and the reinforcing layer need to be damaged during maintenance, and the electric units are inconvenient to take out are solved; and the invention has the beneficial effects of simple structure, good anti-seismic property, convenience in replacement of the electric units, assembly and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a nested cable or optical cable. Background technique [0002] With the development of the national Internet and electric energy industry, electricity and network are inseparable from every household, which is inseparable from people's life. Therefore, the shorter the repair time of cables and optical cables, the smaller the losses caused. [0003] In the prior art, CN210005762U is an embedded optical cable with a plurality of loose tubes, a reinforcing layer is arranged outside the loose tube, an outer sheath is extruded outside the reinforcing layer, and at least one optical communication component is arranged inside the loose tube; It is characterized in that the loose tube is fan-shaped, and the loose tube is composed of a loose tube main body, a clamping unit and a clamping rib, and a fiber cavity is formed inside the loose tube main body, and one end of the clamping rib is connected t...
