Problems solved by technology

However, the existing photoelectric composite cables mainly have the following problems: (1) The cable core is not round. In order to make the product round, a lot of fillers or thick sheaths are needed, which increases the cost; (2) the use of Ointment filling is not environmentally friendly, solidifies when the temperature is low, evaporates when the temperature is high, and the ointment overflows when used indoors or in the cables inserted into the box, causing environmental pollution; (3) The filling rope can only be used for gap filling. Does not effectively block water

Abstract

The invention belongs to the technical field of cables and relates to an optical and electric composite cable with special-shaped filling ropes. The optical and electric composite cable with the special-shaped filling ropes comprises at least power transmission units, at least one optical fiber signal transmission unit, a plurality of the special-shaped filling ropes, a protective layer and an outer sheath and is characterized in that every special-shaped filling rope is composed of a reinforcing component, an internal waterproof layer, a moisture transmission layer and an external waterproof layer, wherein the moisture transmission layer is provided with a plurality of moisture transmission holes communicating the internal waterproof layer and the external waterproof layer; or, the special-shaped filling rope is composed of a reinforcing component, an internal waterproof layer inside the reinforcing component, a moisture transmission layer covering the internal waterproof layer, and an external waterproof layer outside the moisture transmission layer, wherein the moisture transmission layer is provided with a plurality of moisture transmission holes communicating the internal waterproof layer and the external waterproof layer; the external waterproof layer is made of a single-face filmed waterproof tape with a plurality of holes, and the filmed surface of the single-face filmed waterproof taper is adhered to the moisture transmission layer. The optical and electric composite cable with the special-shaped filling ropes has the advantages of being simple in structure, low in cost, environmentally friendly, light weight, easy to produce, excellent in waterproof performance and the like.

Description

Technical field [0001] The present invention is a cable technology field, especially the optoelectronic comprehensive cable with different types of filling ropes. Background technique [0002] With the rapid development of communications, the application of optical fiber cables and wires and cables is increasing.The use of photoelectric composite cables or photoelectric comprehensive cables or photoelectric mixed cables can make electricity and optical direct households. Operators do not need to apply for electricity loads. Therefore, it is increasingly favored by operators.However, the existing photoelectric composite cables mainly have the following problems: (1) the cable core is not round. In order to make the product round, a lot of filling or making a thick cover is needed, which increases the cost;Ointment filling, not environmentally friendly, when the temperature is low, when the temperature is high, evaporates when the temperature is high, and the ointment may be overfl...
