Description

Fiber optical cable

Technical Field

The utility model relates to an optical cable field of making specifically is a fiber optic cable.

Background

The optical cable is mainly composed of optical fibers (thin glass filaments like hair), a plastic protective sleeve and a plastic sheath, and metals such as gold, silver, copper and aluminum are not contained in the optical cable, so that the optical cable generally has no recycling value. The optical cable is a communication line which is formed by a certain number of optical fibers into a cable core in a certain mode, is externally coated with a sheath, and is also coated with an outer protective layer for realizing optical signal transmission.

However, when the external temperature changes, the outer-side protective sleeve of the optical cable contracts and expands due to the principle of expansion with heat and contraction with cold, and the outer-side protective sleeve and the inner-side protective sleeve are separated repeatedly, so that the service life of the outer-side protective sleeve is influenced; the cable cores in the optical cable can be extruded mutually when being bent, the cable cores are isolated only by the insulating layers between the cable cores in the common optical cable, and the insulating layers are damaged when being bent for a long time, so that the isolation of the cable cores is influenced.

Disclosure of Invention

The utility model aims to provide a: the fiber optic cable is provided for solving the problems that the contraction and expansion of the outer side protective sleeve cannot be limited and the insulating structure is single.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fiber optic cable, includes inboard lag, the inner wall of inboard lag is provided with the insulating layer, the inside of insulating layer is provided with the arc rubber pad, and the top of arc rubber pad is provided with the supporting pad, the inboard of insulating layer is provided with the cable core, the top of inboard lag is provided with the connection pad, and the top of connection pad is provided with outside lag.

Preferably, a cavity is arranged between the inner protective sleeve and the outer protective sleeve.

Preferably, the number of the supporting pads is two, and the two supporting pads are symmetrically arranged along the transverse central axis of the arc-shaped rubber pad.

Preferably, the surface of the number protection layer is provided with a fire-proof layer.

Preferably, the inside of the insulating layer is provided with a through hole corresponding to the cable core.

Preferably, the top end of the supporting pad is in accordance with the outer radian of the cable core.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model is provided with the outer protective sleeve, the inner protective sleeve and the connecting pad, when high temperature is met, the outer protective sleeve can expand outwards, the connecting pad can drag the outer protective sleeve, the outer protective sleeve is prevented from being excessively expanded to be separated from the inner protective sleeve, when cold weather is met, the outer protective sleeve can contract, and the connecting pad can support the outer protective sleeve, thereby solving the problem that the contraction and expansion of the outer protective sleeve can not be limited; through setting up supporting pad, arc rubber pad, the cable core of bending department just can with the contact of arc rubber pad when the cable is crooked, thereby the supporting pad just can support the cable core through arc rubber pad and prevent to carry out the problem that the isolated structure is single between the cable core.
