Embodiment 1

[0062] please see Figure 1 to Figure 7 , an easy-to-extend butterfly-shaped lead-in optical cable, has a skeleton part 1, three extension parts 2, three butterfly-shaped light units 3, and a central reinforcement 4. The butterfly-shaped light unit 3 is composed of a butterfly-shaped light unit sheath 31, a light The transmission part 32 and two strengthening elements 33 are composed. The light transmission part is located in the center of the butterfly optical unit sheath, and the two strengthening elements are respectively located above and below the light transmission part. The butterfly light unit sheath connects the light transmission part and the strengthening element Coated, there are tear openings 34 on the edges of the sheath of the butterfly-shaped light unit on the left and right sides of the light transmission part; Composed of engaging parts 13, the frame body 11 has a central cavity 10 inside, and one end of the three frame extension bars 12 extends outward from ...

Embodiment 2

[0064] please see Figure 8 ,refer to Figure 1 to Figure 7 , an easy-to-extend butterfly-shaped lead-in optical cable, which is basically the same as in Example 1, except that the central strengthening member is replaced by a heat-shrinkable tube 5 .

Embodiment 3

[0066] please see Figure 9 ,refer to Figure 1 to Figure 8 , an easy-to-extend butterfly-shaped lead-in optical cable, basically the same as the embodiment 2, the difference is that: the heat-shrinkable tube 5 has a heat-shrinkable groove 51, and the skeleton body has a skeleton body groove 16.

Abstract

The invention belongs to the technical field of communication and optical cables, and discloses an easy-to-expand butterfly-shaped leading-in optical cable, which is provided with a framework part, a plurality of expansion parts and a plurality of butterfly-shaped optical units, the optical cable is characterized in that the framework part is composed of a framework body, a framework extension strip and a clamping part, and a center cavity is formed in the framework body; an expansion cavity is formed in the expansion part; and one clamping part is clamped into the expansion cavity of each expansion part, the clamping parts are attached to the upper surface of the lower side wall body of the expansion part, and a butterfly-shaped optical unit is arranged in each expansion cavity and located above the lower side wall body of the expansion part in the expansion cavity. The invention also discloses a butterfly-shaped introduction photoelectric composite cable and a cable construction method thereof. The invention has the main beneficial effects of simple structure, easiness in manufacturing, high manufacturing qualification rate, easiness in assembly and laying, easiness in expansion and excellent fixing effect.

Description

technical field [0001] The invention belongs to the field of communication and optical cable technology, and in particular relates to an easily expandable butterfly-shaped lead-in optical cable, a photoelectric composite cable and a construction method thereof. Background technique [0002] In the prior art, the butterfly-shaped lead-in optical cable has a single structure and is not easy to expand, which brings great inconvenience to use. Sometimes multiple cores are used as single cores, or they cannot be flexibly assembled on site according to needs, resulting in unnecessary waste. [0003] CN111403101A discloses a hanging type cable and optical cable, which has a central beam tube, a plurality of electrical conductors outside the central beam tube, an outer sheath located outside the electrical conductor, and a plurality of optical fiber ribbons stacked in sequence inside the central beam tube. There is a light transmission part in the optical fiber ribbon, and it is cha...
