Miniature easy-to-branch rat-proof photoelectric composite cable for wireless small base station and preparation method of composite cable

Abstract

The invention discloses a miniature easy-to-branch rat-proof photoelectric composite cable for a wireless small base station and a method for preparing the photoelectric composite cable. The photoelectric composite cable comprises an optical unit located in the center, electric units symmetrically arranged on two sides of the optical unit, and an outer sheath wrapping the optical unit and the electric units. The optical unit comprises a wire core and a rat-proof protection layer wrapping the wire core. The rat-proof protection layer comprises an inner protection layer, a middle protection layer and an outer protection layer, wherein the inner protection layer is a metal armor layer, and the middle protection layer is a rat-proof layer. The rat-proof layer is prepared from the following components in parts by weight: 10 to 12 parts of PV plastic; 23 to 25 parts of ABS plastic; 1.6 to 1.8 parts of compatilizer, namely, ABS-g-MAH; and 2 to 4 parts of plant rat-proof agent. The plant ratproof agent is prepared from the following components in parts by weight: 35 to 41 parts of capsaicine; 42 to 44 parts of berberine; 12 to 14 parts of crotin; 6 to 8 parts of sophocarpidine; and 3 to 5parts of nicotinic acid. The outer wall of the outer protection layer is sawtooth; and a plurality of convex parts and a plurality of concave parts are arranged in the circumferential direction of theouter protection layer, wherein the convex parts and the concave parts are sequentially and alternately arranged. The rat-proof photoelectric composite cable has the advantages of remarkable ratproofeffect, light weight and low cost.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a miniature easy-branch anti-rodent photoelectric composite cable for wireless small base stations, and also relates to a preparation method of a miniature easy-branch anti-rat photoelectric composite cable for wireless small base stations. Background technique [0002] At present, 5G, as one of the symbols of future technological development, has become an important high ground for the world's major operators to compete for. The commercial date of 5G is getting closer and closer, and the market's attention to small base stations is also increasing. Since 5G operating in the higher frequency band will face signal coverage problems, small base stations can act as a "supplement" to expand signal coverage. This can also solve the problem of excessive power consumption of mobile devices due to weak signals and enhanced radio frequency transmission power. Small base stations h...
