Description

Flat photoelectric combined cable for monitoring and shooting

Technical Field

The utility model belongs to the technical field of the optical communication transmission, concretely relates to flat type photoelectricity combination cable is used in surveillance camera.

Background

With the increasing degree of global informatization, users have higher and higher requirements on the content of information services, the manner of providing the content, and the like. Optical fiber communication systems are widely used because of their advantages such as reduced transmission attenuation and large capacity. In the current monitoring camera system, the mode of adding a power line to a coaxial cable is still adopted for monitoring. The wiring mode of the coaxial power supply line is complex, and the signal transmission loss is large. In an intelligent building, a digital community, a campus network and a local area network wiring system, various cables are arranged in the building in a pipe penetrating mode, and due to the fact that indoor wiring environments are complex, after conventional coaxial power supply line wiring is completed, a series of problems that bending radius cannot meet requirements, attenuation is too large, transmission signals are caused to be large in loss and the like may exist. And meanwhile, a large amount of manpower and material resources are needed for maintenance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming above-mentioned background art not enough, providing a flat type photoelectric combined cable is used in surveillance camera, this flat type photoelectric combined cable is used in surveillance camera can realize providing of signal and power simultaneously, has effectively reduced construction work load, and signal transmission is more stable.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a flat photoelectric combination cable for monitoring and camera shooting comprises an optical fiber; the method is characterized in that: the optical fiber is sequentially coated with a low-smoke halogen-free material tight coating layer, an auxiliary reinforcing layer and a sheath layer from inside to outside; two wires arranged in parallel with the optical fibers are also provided.

The two conducting wires and the optical fibers are arranged in a straight line; the sheath of the lead and the sheath layer outside the optical fiber are formed by one-time injection molding.

The two wires are kept at intervals and are connected with each other by a ligament; one of the conducting wires is connected with the sheath layer through another tie, and the conducting wires and the sheath layer are kept at a distance; all the ties, the sheath and the sheath layer are formed by one-time injection molding.

The auxiliary reinforcing layer is formed by wrapping high-strength and low-shrinkage aramid yarns so as to improve the tensile strength of the optical unit part.

The beneficial effects of the utility model

1. The utility model provides a monitoring is made a video recording and is used photoelectricity combination cable, the size is little, and light in weight, softness can and bending property are good, lightly lays, and construction cost is low, and is fast, nimble swift.

2. The combined cable adopts the anti-electromagnetic interference optical fiber to transmit signals; the tensile strength of the photoelectric composite cable can be further improved by the two wires which are arranged in parallel;

3. the combined cable adopts a flat structure design, reduces the production and manufacturing cost on the premise of ensuring the product performance, and is convenient for the assembly of the individual joint of each unit.

Detailed Description

The present invention will be further explained by way of examples with reference to the accompanying drawings.

The flat photoelectric combined cable for monitoring and camera shooting shown in the attached figure comprises an optical fiber 3; the optical fiber is sequentially coated with a tight coating layer, an auxiliary reinforcing layer 5 and a sheath layer 6 from inside to outside; two wires arranged in parallel with the optical fiber are also provided, the wires being formed by the conductor 1 and a jacket covering the conductor.

The tight cladding layer is a low-smoke halogen-free material (LSZH) tight cladding layer 4 with high flame retardance and low shrinkage, so that the optical fiber can be protected, the tensile strength of the optical fiber is further improved, and the excellent transmission performance is ensured.

The auxiliary reinforcing layer adopts aramid yarn with high strength and low shrinkage, so that the tensile strength of the optical unit part is improved.

The sheath layer is made of high-flame-retardant environment-friendly LSZH materials, so that the flame-retardant requirement of the indoor environment is met.

The optical fiber adopts the bending loss insensitive optical fiber with excellent performance, and improves the bending performance and the optical transmission performance of the optical cable product.

The two conducting wires and the optical fibers are arranged in a straight line; the sheath of the lead and the sheath layer outside the optical fiber are formed by one-time injection molding; therefore, the photoelectric combined cable with a flat structure is formed, and the assembly of the monitoring camera joint is facilitated.

Further, the two wires are kept at intervals and are connected with each other through the ligament 2; one of the conducting wires is connected with the sheath layer through another tie, and the conducting wires and the sheath layer are kept at a distance; all the ties, the sheath and the sheath layer are formed by one-time injection molding.

The utility model provides a flat type photoelectricity combination cable is used in surveillance camera, the surveillance camera field on the existing market has been solved, need radiate coaxial cable simultaneously and add the shortcoming of power cord, and fiber transmission distance and signal transmission are more excellent simultaneously, and aramid yarn reinforcement has also improved the tensile strength of combination cable, the while work load that has also significantly reduced constructor.

The above detailed description of the present invention is directed to the skilled in the art, and the idea of the embodiment of the present invention can be changed in the specific implementation manner and the application range, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
