Technical Field

[0021] Embodiment 1:
[0022] Please refer to Figure 1 The utility model provides a magnetic wire 100, which can be bent and stored to form a plurality of turns, and adjacent turns are magnetically adsorbed to facilitate maintaining the bent and stored state.
[0023] Please refer to Figure 2The magnetic wire 100 includes a conductor component 10 and a coating layer that wraps the conductor component 10, wherein the conductor component 10 includes a plurality of wire cores, etc., and the wire cores can be used as signal wires and / or power wires. The conductor component 10 is not an improvement point created by the present invention, and will not be described in detail.
[0024] like Figure 1 and Figure 2 As shown, the two sides of the magnetic wire 100 have a first flat portion 25 and a second flat portion 26 respectively. When the magnetic wire 100 is bent and stored, the first flat portion 25 of one turn can be magnetically attracted to the second flat portion 26 of another adjacent turn. Figure 2 As shown, the cross section of the magnetic wire 100 is oval, having a first flattened position and a second flattened position. The first flattened position is formed by the first flat portion 25, and the second flattened position is formed by the second flat portion 26. Preferably, the first flattened position and the second flattened position are substantially parallel.
[0025] The coating layer of the magnetic wire 100 includes a magnetic layer 20, a graphene shielding layer 30 and a middle layer 40. The graphene shielding layer 30 is arranged between the conductor assembly 10 and the middle layer 40; the middle layer 40 is arranged between the graphene shielding layer 30 and the magnetic layer 20. The magnetic layer 20 is used to realize the magnetic absorption function of the wire; the graphene shielding layer 30 is used to isolate the magnetic interference between the conductor assembly 10 and the magnetic layer 20; the middle layer 40 is used to enhance the swing performance of the wire and enhance the bending and tensile strength of the wire. Among them, the magnetic layer 20 is an integrated coating film made of a mixture of plastic and magnetic powder. The magnetic layer 20 forms a magnetic force after magnetization, and the magnetic wire 100 can be used to store the wire by magnetic winding and stacking in the direction of magnetic attraction. Preferably, the cross section of the magnetic wire 100 is oblate, and the two sides of the oblate parallel to the maximum diameter of the cross section of the magnetic wire 100 are two parallel straight lines. In this way, during the process of magnetic wire 100 being magnetically attracted, wound, bent and stored in the direction of magnetic attraction, the magnetic contact surface can be increased and the magnetic attraction force can be enhanced.
[0026] It can be understood that the magnetic layer 20 can be used as the outermost outer layer of the wire; and the shape of the magnetic wire 100 is to increase the magnetic contact surface. Therefore, by keeping the cross-sectional shape of the magnetic layer 20 the same as the cross-sectional shape of the magnetic wire 100, the purpose of enhancing the magnetic attraction and facilitating the positioning of magnetic attraction winding can be achieved. The cross-sectional shape of the graphene shielding layer 30 and the cross-sectional shape of the middle layer 40 are not limited. The cross-sectional shape of the conductor assembly 10, the cross-sectional shape of the graphene shielding layer 30, and the cross-sectional shape of the middle layer 40 can be circular or square. For example, the cross-sectional shape of the conductor assembly 10 and the cross-sectional shape of the graphene shielding layer 30 are circular, and the cross-sectional shape of the middle layer 40 is square; or the cross-sectional shape of the conductor assembly 10 and the cross-sectional shape of the graphene shielding layer 30 are square, and the cross-sectional shape of the middle layer 40 is circular; or the cross-sectional shape of the conductor assembly 10, the cross-sectional shape of the graphene shielding layer 30, and the cross-sectional shape of the middle layer 40 are all circular or all square.
[0027] The middle quilt layer 40 is an integrated film layer made of insulating material. The insulating material is PP, PVC or TPE rubber, or any combination of the aforementioned materials. Preferably, the thickness of the middle quilt layer 40 does not exceed the thickness of the magnetic layer 20. Specifically, the thickness of the magnetic layer 20 ranges from 0.5 to 1.0 mm; the thickness of the middle quilt layer 40 ranges from 0.3 to 0.4 mm; thereby, while strengthening the swing performance of the wire, it is ensured that the magnetic layer 20 can achieve the magnetic absorption function. The graphene shielding layer 30 is an ultra-thin film layer with a thickness range of 0.03 to 0.05 mm.
[0028] Please refer to Figure 3 Furthermore, the coating layer also includes an appearance layer 50 disposed outside the magnetic layer 20. The appearance layer 50 is used as the appearance of the entire wire and is also used to protect the magnetic layer 20. Preferably, the thickness of the appearance layer 50 does not exceed one third of the thickness of the magnetic layer 20 to ensure that the magnetic layer 20 has sufficient magnetic force to allow the wire to be wound and stacked.
[0029] Please refer to Figures 4 to 6 The conductor assembly 10 includes a power line core 11 and a data line core 12. The number of the power line core 11 and the number of the data line core 12 are set as required. Figure 4 , 5 As shown, the number of power line cores 11 and the number of data line cores 12 may be equal; Figure 6 As shown, the number of power line cores 11 and the number of data line cores 12 may not be equal. The number of power line cores 11 and the number of data line cores 12 are equal. It can be understood that the conductor component 10 can also be a thin sheet metal foil conductor with power transmission function and data transmission function. The core wire or metal foil conductor is covered with an insulating material to form the conductor component 10.
[0030] The utility model can ensure the magnetic attraction function of the magnetic layer 20 while increasing the swing performance of the wire and increasing the bending and tensile strength of the wire through the middle layer 40; and increase the magnetic isolation and shielding performance between the conductor component 10 and the magnetic layer 20 through the graphene shielding layer 30.
[0031] For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
