Description

Technical Field

[0001] The utility model relates to the technical field of composite cables, in particular to a tensile-resistant graphene composite cable. Background Art

[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, used to connect circuits, electrical appliances, etc., to transmit electricity or information from one place to another. It has been increasingly widely used for its advantages such as safety, reliability, and beautification of cities and factory layouts. It is mainly composed of three parts: wire core (conductor), insulation layer and sheath. Graphene cable is a new type of cable material designed and manufactured using the excellent properties of graphene.

[0003] However, in the prior art, composite cables often protect the internal wire cores by means of an outer protective sheath, and the wire cores and the protective sheaths are mostly directly fixed. As a result, when the outer protective sheath is pulled during the laying or use of the cable, the internal wire cores will also be directly pulled, which can easily cause damage to the internal wire cores, greatly reducing the safety of the composite cable when in use. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when the outer protective sheath of the graphene composite cable is used, it is easy to cause damage to the internal core, and to propose a tensile-resistant graphene composite cable.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a cable core, the outer surface of the cable core is wrapped and fixed with an inner fastening wrapping layer, the outer surface of the inner fastening wrapping layer is wrapped and fixed with an elastic insulating wrapping layer, the outer surface of the elastic insulating wrapping layer is wrapped and fixed with an elastic protective net, the outer surface of the elastic protective net is wrapped and fixed with a graphene insulating protective sleeve, and the outer surface of the graphene insulating protective sleeve is wrapped and fixed with an anti-corrosion and anti-oxidation outer jacket.

[0006] Preferably, the cable core on the inner side of the inner fastening wrapping layer is arranged as two circles of inner and outer arrangements, the outer surface of the inner circle cable core is wrapped and fixed with the outer fastening wrapping layer, and the outer surface of the outer fastening wrapping layer is wrapped and fixed with the elastic inner wrapping layer.

[0007] Preferably, both ends of the elastic protective net are fixed with a reinforcing connection layer, and the reinforcing connection layer is wrapped and fixed on the outer surface of the end of the elastic insulating wrapping layer, and the outer surfaces of the two reinforcing connection layers are fixed on the inner wall of the graphene insulating protective sleeve.

[0008] Preferably, the thickness of the inner fastening wrapping layer is 0.6-1.0 mm, and the thickness of the elastic insulating wrapping layer is 1.2-1.5 mm.

[0009] Preferably, the thickness of the elastic protective net is 2.0-2.5 mm, and the thickness of the anti-corrosion and anti-oxidation jacket is 1.2-1.5 mm.

[0010] Preferably, the thickness of the outer fastening wrapping layer is 0.6-1.0 mm, and the thickness of the elastic inner wrapping layer is 0.8-1.2 mm.

[0011] Preferably, the thickness of the reinforcing connection layer is equal to the thickness of the elastic protection net 4, and the thickness of the elastic protection net is 1.2-1.5 mm.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, through the elastically connected pulling structure, when the outer protective cover is pulled and the gripping force is insufficient, most of the pulling force acts on the elastic protective net when the outer protective cover is pulled, and the elastic protective net is deformed for buffering protection, thereby solving the problem of the existing graphene composite cable that the internal wire core is easily damaged when the outer protective cover is pulled during use, and greatly improving the tensile performance of the cable during use.

[0014] 2. In the utility model, the internal cable core can be wrapped and fixed in layers through the cooperation of the inner fastening wrapping layer and the outer fastening wrapping layer, so that the cable cores are more firmly connected, and the layered design of the inner and outer cable cores ensures that when the cable is pulled, the inner and outer layers will not be wrapped and linked, thereby better protecting the cable cores.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] like Figure 1-4 As shown, the utility model provides a tensile-resistant graphene composite cable, including a cable core 1: an inner fastening wrapping layer 2 is wrapped and fixed on the outer surface of the cable core 1, and the cable core 1 on the inner side of the inner fastening wrapping layer 2 is arranged as two circles of inner and outer arrangements, the outer surface of the inner circle cable core 1 is wrapped and fixed with an outer fastening wrapping layer 7, and the outer surface of the outer fastening wrapping layer 7 is wrapped and fixed with an elastic inner wrapping layer 8, the outer surface of the inner fastening wrapping layer 2 is wrapped and fixed with an elastic insulating wrapping layer 3, the outer surface of the elastic insulating wrapping layer 3 is wrapped and fixed with an elastic protective net 4, both ends of the elastic protective net 4 are fixed with reinforcing connection layers 9, and the reinforcing connection layer 9 is wrapped and fixed on the outer surface of the end of the elastic insulating wrapping layer 3, the outer surfaces of the two reinforcing connection layers 9 are fixed on the inner wall of the graphene insulating protective sleeve 5, the outer surface of the elastic protective net 4 is wrapped and fixed with a graphene insulating protective sleeve 5, and the outer surface of the graphene insulating protective sleeve 5 is wrapped and fixed with an anti-corrosion and anti-oxidation jacket 6.

[0023] The following is a detailed description of the specific settings and functions of this embodiment: the thickness of the inner fastening wrapping layer 2 is 0.6-1.0mm, the thickness of the elastic insulating wrapping layer 3 is 1.2-1.5mm, the inner structure is protected by the anti-corrosion and anti-oxidation jacket 6, and in combination with the graphene insulating protective sleeve 5, the overall tensile strength of the cable can be improved, the thickness of the elastic protective net 4 is 2.0-2.5mm, and the elastic protective net 4 will first deform when subjected to tension, and after reaching the maximum deformation, the tension will fully act on the elastic insulating wrapping layer 3 On the other hand, the cable core 1 can be better protected, the anti-corrosion and anti-oxidation jacket 6 has a thickness of 1.2-1.5mm, the thickness of the outer fastening wrapping layer 7 is 0.6-1.0mm, the thickness of the elastic inner wrapping layer 8 is 0.8-1.2mm, and the thickness of the reinforced connection layer 9 is equal to the thickness of the elastic protective net 4, ensuring the flatness of the outer surface of the elastic protective net 4 and the reinforced connection layer 9, and ensuring the firmness of the connection between the graphene insulating protective sleeve 5 and the elastic protective net 4 and the reinforced connection layer 9. The thickness of the elastic protective net 4 is 1.2-1.5mm.

[0024] The use method and working principle of the device: The anti-corrosion and anti-oxidation jacket 6 is used to protect the outermost layer of the cable to prevent the influence of sunlight and corrosive substances on the cable. At the same time, the inner graphene insulating protective jacket 5, elastic protective net 4, elastic insulating wrapping layer 3 and inner fastening wrapping layer 2 can also be protected, so that the graphene insulating protective jacket 5, elastic protective net 4, elastic insulating wrapping layer 3 and inner fastening wrapping layer 2 can give full play to their protective effect. When the outer surface of the anti-corrosion and anti-oxidation jacket 6 is pulled, the gripping force acts on the outer surface of the anti-corrosion and anti-oxidation jacket 6. On the surface, the anti-corrosion and anti-oxidation jacket 6 resists the tensile force through its own strength. When the anti-corrosion and anti-oxidation jacket 6 is deformed by being pulled, due to the elastic design of the elastic protective net 4 and the graphene insulating protective sleeve 5 is not in direct contact with the elastic insulating wrapping layer 3, the graphene insulating protective sleeve 5 will pull the elastic protective net 4 to deform as the anti-corrosion and anti-oxidation jacket 6 deforms. Due to the elastic design of the elastic protective net 4, when it is deformed, the pulling force will not be entirely applied to the elastic insulating wrapping layer 3, thereby protecting the internal cable core 1.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
