technical field

The utility model relates to a cable, in particular to a security cable.

Background technique

Compared with industries such as electric power, communications, and radio and television, the cables used in the security industry have objective conditions such as late start, backward technology, and imperfect industry standards. During the communication equipment exhibition, the security cables used to connect the communication equipment are usually used for signal transmission, power transmission, alarm and other functions. The security cables in the prior art use a pair of twisted signal wires, the core wires of which are conventional annealed copper or tinned annealed copper stranded conductors, and the pair of signal wires are wrapped in a plastic outer sheath. As a result, the security cables in the prior art are used in relatively harsh environments such as heavy load, high tensile strength, and strong ultraviolet rays, and there are relatively large safety hazards, and they cannot effectively protect the communication equipment connected to them from theft. .

Detailed ways

As shown in FIG. 1 , it is a schematic cross-sectional structure diagram of a security cable 10 according to an embodiment of the present invention. The security cable 10 includes: an outer sheath 100 , a shielding layer 200 , a first insulated wire 310 , a second insulated wire 320 , a third insulated wire 330 , a steel cable structure 400 and a reinforcing wire 500 .

In order to effectively prevent damage to the outer sheath 100 by ultraviolet rays and prolong the service life of the security cable 10, the outer wall of the outer sheath 100 is coated with an anti-ultraviolet material layer (not shown in the figure).

In order to facilitate the laying and use of the security cable 10, prevent the position from moving, and prevent people from stepping on it and easily falling due to rolling, the cross-section of the outer sheath 100 is a flat structure. The extended isolation belt 600 is integrally formed with the outer sheath 100 in actual production. The steel cable structure 400 is arranged in the first channel 110 surrounded by the isolation belt 600 and the outer sheath 100, and the first insulated wire 310, the second insulated wire 320 and the third insulated wire 330 are arranged side by side between the isolation belt 600 and the outer sheath 100 within the second channel 120 .
