Abstract

The invention belongs to the technical field of optical cables and relates to a reinforced rat-proof threaded steel tube bow-type drop cable. According to the reinforced rat-proof threaded steel tube bow-type drop cable,the tensile and compressive properties of the cable can be improved, and the cable can meet a long-span laying condition, and meanwhile, the rat-proof performance of the cable is improved. The reinforced rat-proof threaded steel tube bow-type drop cable comprises a first outer sheath, an optical cable sub-unit, a glass fiber band, a second outer sheath, a second reinforcing piece and a connecting piece; the glass fiber band sleeves the outer wall of an optical cable sub-unit through a tight sleeving process; the first outer sheath sleeves the circumferential outer wall of the glass fiber band through the tight sleeving process; the first outer sheath is internally provided with two groups of first reinforcing pieces used for improving the tensile performance of the optical cable; the axes of the two groups of first reinforcing pieces are parallel to the axis of the optical cable sub-unit; the two groups of first reinforcing pieces are symmetrical about the axis of the optical cable sub-unit; the second outer sheath sleeves the circumferential outer wall of the second reinforcing piece through the tight sleeving process; and the second outer sheath is fixedly connected with the outer wall of the first outer sheath through the connecting piece.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a reinforced rodent-proof threaded steel pipe butterfly-shaped lead-in optical cable. Background technique [0002] With the continuous deepening of China's FTTH network construction, the research and development of new optical cables is promoted to meet the market's requirements for convenient construction, flexible networking, line safety and convenient maintenance. [0003] At present, the commonly used butterfly drop optical cable has the problem of poor tensile and compressive resistance in use, and cannot be applied to long-span laying conditions, which increases unnecessary labor and material costs. SUMMARY OF THE INVENTION [0004] In order to solve the above-mentioned technical problems, the present invention provides a butterfly-shaped introduction of a reinforced rat-proof threaded steel pipe which is beneficial to improve the tensile and compressive performan...
