Disclosure of utility model

Aiming at the problems, the utility model provides a communication cable for an Internet of things system, which well solves the problem that the extrusion caused by bending deformation of a copper core and an external protective layer is easy to damage due to the fact that the filled basalt fiber rope is woven inside the cable in the prior art when the cable is bent.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a communication cable for internet of things system, includes the inoxidizing coating, be provided with the circuit isolation cover in the protection layer, the circuit isolation cover includes the isolating ring and encircles a plurality of baffle plates of isolating ring inner wall body coupling, be provided with the communication line between the baffle plate, can separate the communication line through the circuit isolation cover, there is the clearance between the baffle plate simultaneously can make the communication line buckle more easily, is difficult to make the protective layer break when buckling.

Further, the circuit isolation sleeve is made of low-density polyethylene, and the low-density polyethylene is softer, so that extrusion force applied to the communication line during bending is relieved.

Furthermore, the section of the baffle plate is conical towards the center of the isolating ring, so that a triangular gap is formed between the baffle plates surrounding the inner wall of the isolating ring, and the communication line is clamped in the triangular gap.

Furthermore, the two side edges of the baffle plate, which are close to the center of the isolating ring, are provided with bosses, and the communication wires are further limited from falling out from between the baffle plate through the bosses.

Further, the protective layer comprises an isolation layer, a woven layer and a flame-retardant layer which are sequentially coated on the circuit isolation sleeve, and the protective layer is used for improving the protective effects of isolation shielding, anti-pulling and flame retardance on the signal wire.

Further, the isolation layer is aluminum foil, and the aluminum foil layer has better signal shielding effect.

Furthermore, the weaving layer is formed by weaving the red copper wires and the flax material, and the anti-pulling capability of the flax material is stronger when the signal shielding effect is further improved through the red copper wires.

Furthermore, the flame-retardant layer is made of polyvinyl chloride, and the polyvinyl chloride is low in price and has a good flame-retardant effect.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model can separate and arrange the signal wires through the wire isolation sleeve, keep the arrangement structure of the internal wires regular, simultaneously lead the cable wires to be easier to bend, effectively relieve the extrusion force suffered by the protective layer and the internal wires during bending, and prevent the wires from being damaged.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, a communication cable for an internet of things system comprises a protective layer 1, a line isolation sleeve 2 is arranged in the protective layer 1, the line isolation sleeve 2 comprises an isolation ring 3 and six baffle plates 4 integrally connected with the inner wall of the isolation ring 3, the six baffle plates 4 are uniformly distributed around the inner wall of the isolation ring 3, and communication lines 5 are arranged between the baffle plates 4.

In this embodiment, the material of the circuit isolation sleeve 2 is low-density polyethylene, which is softer, so as to relieve the extrusion force applied to the communication line 5 during bending.

In this embodiment, the cross section of the baffle plate 4 is tapered toward the center of the isolating ring 3, so that a triangular gap is formed between the baffle plates 4 surrounding the inner wall of the isolating ring 3, and the communication line 5 is clamped in the triangular gap.
