The following describes the implementation of the present invention in detail with reference to specific embodiments.
Referring to fig. 1, a preferred embodiment of the present invention is provided.
The utility model provides a cable that contains electroplating shielding layer 22, include: cable core 1, protective layer 2 and oversheath 3.
Specifically, the cable core 1, the protective layer 2 and the outer sheath 3 are sequentially arranged from inside to outside to form the cable containing the electroplated shielding layer 22 in the embodiment; more specifically, the cable core 1 comprises a plurality of core wires 10, an insulating layer 101 is arranged outside each core wire 10, each core wire 10 is formed by collecting a plurality of copper wires, and the insulating layer 101 is required outside to bundle the plurality of copper wires inside so as to maintain a stable appearance and perform insulation protection on the copper wires; more specifically, a plurality of core wires 10 are twisted with each other to form the cable core 1.
More specifically, the plating shielding layer 22 is provided outside the non-hygroscopic protective layer 2, and the plating shielding layer 22 is provided outside the non-hygroscopic belting layer 21 by means of plating, and it can be understood that if the non-hygroscopic belting layer 21 is not provided, the plating shielding layer 22 needs to be provided directly on the cable core 1 by means of plating, and this behavior has a risk of causing damage to the cable core 1, so the non-hygroscopic belting layer 21 also has a function for plating the shielding layer 22.
More specifically, the material of the plating shielding layer 22 is a graphene material, the graphene material is a new material which is tightly stacked with sp hybridized and connected carbon atoms into a single-layer two-dimensional honeycomb lattice structure, and the graphene has excellent optical, electrical and mechanical properties, and more specifically, the graphene material has high strength, good toughness and can be bent, so that in the practical use of the cable, the bending and collision of the cable do not affect the plating shielding layer 22, and the cable has high stability and safety.
More specifically, the electric field generates a magnetic field, and the strength of the generated magnetic field is related to the strength of the electric field, so that when the cable transports electricity, a strong magnetic field is generated, and the strong magnetic field affects the normal use of other electronic devices, and the plating shielding layer 22 functions to block the propagation path of electromagnetic waves through electromagnetic shielding, thereby preventing the cable from radiating electromagnetic waves to interfere with external devices.
More specifically, the conventional cable shielding layer adopts a mode that metal wires are meshed and woven by taking the cable core 1 as a center to form a shielding net to electromagnetically shield the cable, and in the embodiment, the shielding layer is arranged in an electroplating mode, so that the cable shielding layer has two advantages of high production efficiency and small cable outer diameter.
More specifically, the shielding layer of metal wire needs to use a braiding process, and the plating shielding layer 22 needs to use a plating process, it is understood that the production efficiency of the plating process is higher than that of the braiding process, therefore, the selection of the plating shielding layer 22 to replace the shielding layer of metal wire can improve the production efficiency of the cable, resulting in an advantage in production efficiency.
More specifically, the conductivity of the graphene material is better than that of the metal wire, so that the thickness of the plating shielding layer 22 is significantly reduced on the premise of maintaining the same shielding effect as that of the metal wire shielding layer; more specifically, when the shielding suppression coefficient is 0.01, the thickness of the metal wire close layer is 0.25 to 0.28mm, and the thickness of the plating shielding layer 22 is 0.08 to 0.1mm.
More specifically, the outer sheath 3 is disposed outside the protection layer 2, and the outer sheath 3 is used to protect the cable core 1 and the protection layer 2 inside, it can be understood that if the plating shielding layer 22 is directly exposed outside, the plating shielding layer 22 will be continuously damaged by the external environment in actual use, so that the electromagnetic shielding effect of the plating shielding layer 22 is reduced, and the expected service life of the cable is greatly shortened, therefore, the outer sheath 3 needs to be disposed outside the protection layer 2 to protect the cable from the external environment.
The utility model discloses 1 skin at the cable core has set up non-hygroscopicity band layer 21 to electroplate shielding layer 22 through electroplating process setting at non-hygroscopicity band layer 21 skin, the material of electroplating shielding layer 22 is graphite alkene material, compare traditional metal wire shielding layer, the thickness of electroplating shielding layer 22 is less, and, the efficiency that uses electroplating process to set up electroplating shielding layer 22 will be higher than the efficiency that uses weaving production technology to set up the metal wire shielding layer, the problem that the efficiency is low when having solved cable core 1 inside for the cable among the traditional approach sets up the shielding layer.
In some embodiments, the number of cords 10 is 2~9.
Specifically, the cable core 1 is formed by twisting a plurality of core wires 10 with each other, and it is understood that a single core wire 10 cannot be twisted by itself, so that a minimum of two core wires 10 are required in the cable core 1, and on the other hand, when the number of core wires 10 is too large, since the toughness of the core wires 10 themselves is limited, it is difficult to twist with each other to form the cable core 1, so that the number of core wires 10 in the cable is at most 9.
In some embodiments, the cable core 1 further comprises a non-hygroscopic filler.
Specifically, the cable core 1 is formed by twisting a plurality of cables, and the outer side is covered with the protective layer 2, and it can be understood that the protective layer 2 covers the cable core 1, and if the cable core 1 has an irregular shape, the arrangement of the protective layer 2 is affected, and there is a problem that the arrangement of the protective layer 2 is not uniform, so that the cross section of the cable core 1 is maintained to be circular.
More specifically, when the number of the core wires 10 is too small, the outer shape of the cable core 1 formed by twisting the core wires 10 is irregular, and therefore, it is necessary to supplement the cable core 1 with a non-hygroscopic filler so that the outer shape of the cable core 1 is changed from an irregular state to a regular state.
More specifically, the cross section of the cable core 1 composed of the non-hygroscopic filler and the plurality of core wires 10 is approximately circular, and at this time, the overall shape of the cable core 1 is a cylinder, and it can be understood that the cross section of the cable core 1 composed of the non-hygroscopic filler and the plurality of core wires 10 is not perfectly circular, but is circular very close to the perfect circular on the premise of allowing a certain error range.
More specifically, non-hygroscopicity filler adopts non-hygroscopicity material to make, and non-hygroscopicity material refers to the material that can not absorb moisture from the environment, the utility model provides a non-hygroscopicity filler can be any one in rubber strip, PP filling rope, the plastic strip.
In some embodiments, the non-hygroscopic filler has a heat resistance of 30-50 ℃.
Specifically, the non-hygroscopic filler has a non-hygroscopic property, so that the non-hygroscopic property can be ensured not to absorb moisture to cause a short circuit in the cable core 1, and in addition, the non-hygroscopic filler needs to have a heat-resistant capability to adapt to the environment of the cable core 1 in the cable because the cable itself generates heat to cause the temperature rise of the cable core 1 when transmitting current.
More specifically, the temperature of the cable core 1 is 30 to 50 ℃ under the premise of normal operation, so that the heat resistance of the non-hygroscopic filler is 30 to 50 ℃.
In some embodiments, the insulating layer 101 is made of one of polyvinyl chloride, polyethylene, and fluorinated ethylene propylene.
Specifically, the insulating layer 101 is a structure provided outside the core wire 10 for insulating and protecting the core wire 10, and it is understood that the insulating layer 101 needs to be made of an insulating material whose weight and price are not easily too high in consideration of the practical application of the cable, and thus plastic is used as the insulating material of the present embodiment.
More specifically, the insulating layer 101 is made of one of polyvinyl chloride, polyethylene, and fluorinated ethylene propylene.
In some embodiments, the wall thickness of the insulating layer 101 is 0.2 to 0.4mm.
Specifically, the properties of the three materials of polyvinyl chloride, polyethylene and polyperfluoroethylene propylene are similar, and any one of the three materials is selected as the insulating layer 101, and the effect is substantially the same, it can be understood that when the material of the insulating layer 101 is limited to the three materials, the wall thickness of the insulating layer 101 is also limited to a certain range, and the wall thickness of the insulating layer 101 in this embodiment is 0.2 to 0.4mm.
In some embodiments, the plating shield 22 further includes an adhesive.
Specifically, the electroplating shielding layer 22 is made of a graphene material, and the graphene material has the advantages of softness and high conformability, and is not easy to puncture the cable core 1 and the outer sheath 3, and it can be understood that, because the electroplating shielding layer 22 has the specific characteristic of high softness, the cable is bent in the using process of the cable, and the safety of the cable is not affected.
More specifically, the graphene added with certain impurities is more excellent in conductivity than pure graphene, more specifically, the adhesive is added into the graphene material, so that the graphene material is easy to shape, and convenience is provided for arranging the graphene outside the cable core 1 by an electroplating process.
In one embodiment, the outer sheath is made of silicone rubber.
Specifically, the outer sheath 3 is disposed outside the protective layer 2 and is used for protecting the internal cable core 1 and the protective layer 2, and therefore the outer sheath 3 needs to have a performance of protecting the internal structure from an external environment.
More specifically, silicone rubber refers to rubber having a main chain composed of alternating silicon and oxygen atoms, with two organic groups typically attached to the silicon atoms; more specifically, the silicone rubber has remarkable high-temperature stability, when the cable transports power, the stability of the cable core 1 can be improved, and the silicone rubber can keep the stability of performance in an environment with increased temperature and continuously protect the cable.
In some embodiments, the outer sheath 3 has a wall thickness of 0.5 to 0.7mm.
Specifically, in the present embodiment, the outer sheath 3 made of silicone rubber has a wall thickness of 0.5 to 0.7mm within a certain range.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
