Abstract
Disclosed is a novel rat-proof optical cable, which comprises a cable core and a sheath. The sheath is made of corrosion-resistant rubber and is provided with a metallic fabric layer in the middle position, a protective layer woven with non-magnetic metal material is arranged between the cable core and the sheath, the cable core includes an inner layer and an outer layer, the outer layer includes four arc cable cores with a section shaped as a 1/4 cambered surface, the inner layer includes a plurality of cable cores with an annular section, and the cable inner layer is wrapped by the cable outer layer. The novel rat-proof optical cable is reasonable in structure and convenient in processing, the optical cable can be effectively protected and thus the normal operation of communication equipment can be ensured.
Description
Technical field
The utility model relates to electric power optical cable, is specially a kind of Novel anti-mouse evil optical cable of built-in protective seam.
Background technology
In existing cable production technology; mostly be to comprise that cable core and sheath form; wherein cable core is operation element; sheath typically uses anti-corrosive rubber and makes; cable core there is certain protective effect; but only only limit to chemical corrosion etc.; in the circuit that set up in the high-altitude; tool has certain effect; but in the underground cables erection process; then can't protect cable to exempt the plague of rats and damage by worms; and along with progress and the communication of present erecting cable technology; electric power; municipal development, present cable all have from the high-altitude sets up the development trend that turns to embedded underground, often can be gnawed by underground mouse ant; cause short circuit; have a power failure; the control maloperation; the situations such as communication and signal interruption occur, and cause great harm for personal property and social safety.
The utility model content
The technical matters that the utility model solves is to provide a kind of Novel anti-mouse evil optical cable, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of Novel anti-mouse evil optical cable, comprise cable core and sheath, wherein, sheath is that anti-corrosive rubber is made, the outsourcing cable core, and the rubber layer centre position is provided with the layer of metal tissue layer simultaneously, in addition, also be provided with protective seam between cable core and sheath, described protective seam is that the nonmagnetic material braiding forms, and is lined with glass fibre in metal material fabric centre; Described cable core comprises internal layer with outer, and its skin comprises the arc cable core that four tangent planes are 1/4 cambered surface, and internal layer is that some tangent planes are circular cable core, the outer outsourcing cable core of cable core internal layer.
In the utility model, the circular cable core of described cable core internal layer is preferably 4 ~ 8.
Beneficial effect: the utility model has effectively strengthened the physical strength of cable core on the basis that increases a small amount of production cost, can prevent effectively that the mouse ant is to the destruction of cable, simultaneously, inner double-deck cable core structure can effectively guarantee communication quality on the basis that increases the metal fabric layer, thereby is suitable for promoting the use of in the optical cable laying field.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of Novel anti-mouse evil optical cable of Fig. 1 in the present embodiment, comprises cable core and sheath 1, and metal fabric layer 2 is positioned at sheath 1 centre position, and cable core is positioned at protective seam 3 inboards, comprises outer arcuate cable core 4 and inner circular cable core 5.
Wherein, sheath 1 is made for anti-corrosive rubber, and described protective seam 3 forms for the nonmagnetic material braiding, and is lined with glass fibre in protective seam 3 centres; And outer arcuate cable core 4 is combined by the arc cable core of four 1/4 cambered surfaces, and inner circular cable core 5 comprises that five undercut faces are circular cable core.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
