The present invention mainly proposes a shielding wire 100 for winding or adhering on a shielded body, which may be a wire, a signal line, a transformer, a power source, a vacuum tube, a photomultiplier tube, a magnetron, a transistor, or the like. The shielding wire 100 may be attached to or wound around a shielded body to prevent electromagnetic fields or electromagnetic waves from radiating outward or inward.
The specific structure of the shield wire 100 will be mainly described below.
Referring to fig. 1 to 7, in an embodiment of the invention, a shielding unit 1 is included, the shielding unit 1 has a flexible elongated shape, and the shielding unit 1 includes: the flexible nonmetal wire core 2 is square in cross section, and the maximum side length of the flexible nonmetal wire core 2 is 1.5 mu m-3 cm; the shielding coating 3 covers the outer surface of the nonmetal wire core, the cross section of the shielding coating 3 is square, the thickness of the shielding coating 3 is 0.01-3 mu m, and the shielding coating 3 is an electromagnetic shielding layer 31 and/or a magnetic shielding layer 32; wherein the electromagnetic shielding layer 31 is any one or more of a copper layer, a zinc layer, an indium layer, a tin layer, a silver layer, a gold layer, an aluminum layer, a titanium layer, an iron layer, a magnesium layer, and a lead layer; the magnetic shielding layer 32 is any one or more of a cobalt layer, a nickel layer, a stainless steel layer, and a ferromagnetic alloy layer.
The flexible nonmetal wire core 2 is used for bearing the shielding coating 3, and the cross section of the flexible nonmetal wire core 2 can be square or rectangular. After the flexible nonmetal wire core 2 is cross-sectioned, the maximum side length dimension of the flexible nonmetal wire core 2 is in a section with the activity being more than or equal to 1.5 mu m and less than or equal to 3cm, so that the flexible nonmetal wire core 2 has good mechanical flexibility. The whole of the flexible nonmetal core 2 can be in a rectangular strip shape, so that the flexible nonmetal core 2 has a flat surface. The flexible nonmetallic core 2 may be made of rubber, silica gel, thermoplastic elastomer material, thermoplastic polyurethane elastomer rubber, polyvinyl chloride, polyethylene, crosslinked polyethylene, foamed polyethylene, polytetrafluoroethylene, or the like, and is not particularly limited herein. The shielding plating layer 3 is used for shielding electromagnetic waves and magnetic shielding. The shield plating layer 3 may be formed by vacuum plating, sputtering plating, or water plating. The shielding plating layer 3 may be made of metal, such as permalloy, iron alloy, copper alloy, aluminum or aluminum alloy, etc., so that the shielding plating layer 3 can be electrically conductive. The thickness of the shielding coating 3 is within a range of 0.01 μm or more and 3 μm or less, so that the shielding performance can be ensured, and the shielding coating has good oxidation resistance and corrosion resistance.
When the shield wire 100 is used, the shield wire 100 may be wound around the surface of the shielded body or may be stuck to the surface of the shielded body, for example, when the shielded body is a signal wire, the shield wire 100 may be tightly wound around the shielded body in a spiral shape or may be stuck to the surface of the signal wire. When the shielded body is a power source, the shielding wires 100 may be attached to the signal lines along the length direction of the power source, the number of the shielding lines may be plural, and the plurality of shielding wires 100 may be arranged along the circumferential direction of the shielded body.
The electromagnetic shielding layer 31 can reflect and absorb incident waves. Any one or more of a copper layer, a zinc layer, an indium layer, a tin layer, a silver layer, a gold layer, an aluminum layer, a titanium layer, an iron layer, a magnesium layer, and a lead layer is/are the electromagnetic shielding layer 31, which is favorable for absorbing electromagnetic waves. The magnetic shield 32 acts as a shunt to the magnetic flux such that the magnetic field inside the magnetic shield 32 is reduced. Any one or more of the cobalt layer, the nickel layer, the stainless steel layer, and the ferromagnetic alloy layer is the magnetic shielding layer 32, which is advantageous in reducing the magnetic resistance in the electromagnetic shielding layer 31.
According to the shielding wire 100, the cross section of the flexible nonmetal wire core 2 is square, and the shielding coating 3 covers the outer surface of the nonmetal wire core, so that the shielding wire 100 has a flat surface, when the shielding wire 100 is wound or stuck on a shielded body, the surface of the shielding wire 100 can be attached to the surface of the shielded body, the contact area between the shielding wire 100 and the shielded body is greatly increased, and therefore foreign matters are not easy to enter between the square shielding wire 100 and the shielded body (compared with the round shielding wire 100); meanwhile, when the shielding wires 100 cover the shielded body, the side walls of the adjacent shielding wires 100 can be bonded, compared with the bonding of the round shielding wires, the bonding area of the square shielding wires is greatly increased, so that foreign matters cannot enter between the shielding wires 100, the influence of the foreign matters on the shielding wires 100 and the shielded body can be avoided, and the working stability of the shielding wires 100 is greatly improved; meanwhile, since the shielding wires 100 have flat surfaces, the contact area and coverage area of the shielding wires 100 with the shielded body are increased (compared with a circular wire, the thickness of the shielding layer between two adjacent shielding wires 100 is increased), and the shielding effect of the shielding wires 100 is improved. In addition, since the shielding plating layer 3 is the electromagnetic shielding layer 31 and/or the magnetic shielding layer 32, the shielding plating layer 3 can isolate an electric field when the shielding plating layer 3 is the electromagnetic shielding layer 31; when the shielding coating 3 is a magnetic shielding layer 32, the shielding coating 3 can isolate a magnetic field; when the shielding plating layer 3 is the electromagnetic shielding layer 31 and the magnetic shielding, the shielding plating layer 3 can isolate an electric field and an isolated magnetic field at the same time, thus improving the shielding effect of the shielding wire 100.
Specifically, in this embodiment, the shielding wire 100 further includes an insulating protective sleeve 4 and at least two shielding units 1, where the side surfaces of the two shielding units 1 are attached to each other, and are disposed in parallel in the insulating protective sleeve 4, and the insulating protective sleeve 4 is disposed in a square shape; the shielding plating layers 3 of at least two shielding units 1 are respectively an electromagnetic shielding layer 31 and a magnetic shielding layer 32, the number of the shielding units 1 is multiple, the shielding units 1 with the electromagnetic shielding layers 31 and the shielding units 1 with the magnetic shielding layers 32 are sequentially staggered, and one side face of each two adjacent shielding units 1 is attached.
The insulation protection sleeve 4 serves to prevent the shielding plating layer 3 of the shielding unit 1 from being electrically connected with external foreign substances and to protect the shielding plating layer 3 from scratches or scratches. The material of the insulating protective cover 4 may be polyvinyl chloride, polyethylene, crosslinked polyethylene, foamed polyethylene, polytetrafluoroethylene, or the like, and is not particularly limited herein. Before the insulating protective sleeve 4 sleeves the two shielding units 1, one side of the minimum area of the two shielding units 1 can be attached, and one side of the maximum area of the two shielding units 1 can be attached. The two shielding units 1 are arranged on the insulating protective sleeve 4, so that the shielding coating 3 can be prevented from being electrically connected with external equipment, and meanwhile, foreign matters can be prevented from scratching or scratching the shielding coating 3, and the shielding coating 3 is prevented from being damaged.
When the shielding plating layer 3 of one of the shielding units 1 is the electromagnetic shielding layer 31, the electromagnetic shielding layer 31 can shield electromagnetic waves, and when the shielding plating layer 3 of the other shielding unit 1 is the magnetic shielding layer 32, the magnetic shielding layer 32 can shield a magnetic field, so that when the shielding wire 100 works in an environment with both the magnetic field and the electromagnetic waves, the shielding wire 100 can eliminate the interference of the electromagnetic waves and the interference of the magnetic field, and the shielding effect of the shielding wire 100 is improved.
The number of the shielding units 1 is plural, that is, three or more, for example, when the total number of the shielding units 1 is three, the shielding units 1 having the magnetic shielding layer 32 may be one or two, and when the total number of the shielding units 1 is four, the shielding units 1 having the magnetic shielding layer 32 may be two. The plurality of shielding units 1 having the magnetic shielding layer 32 and the plurality of shielding units 1 having the electromagnetic shielding layer 31 may be sequentially staggered in the same direction. In addition, one side surface of two adjacent shielding units 1 may be bonded to the largest area side of two adjacent shielding units 1, or the smallest area side of two adjacent shielding units 1 may be bonded to each other, and the present invention is not limited thereto. When the shielding units 1 having the plurality of electromagnetic shielding layers 31 and the shielding units 1 having the plurality of magnetic shielding layers 32 are sequentially staggered, since the side surfaces of the shielding units 1 are attached to each other, the reliability of the entire shielding wire 100 can be improved. Because the shielding units 1 of the electromagnetic shielding layers 31 and the shielding units 1 with the magnetic shielding layers 32 are staggered in sequence, the whole width of the shielding wire 100 can be increased, and the shielding area of the shielding wire 100 is increased. When the surface of the shielding wire 100 is bonded to the shielded body, the shielding effect of the shielding wire 100 can be further improved.
In some examples, the shielding plating 3 is a vacuum plating; and/or, the flexible nonmetal core 2 is a flexible rubber core. The shielding coating 3 is a vacuum coating, which is favorable for controlling the thickness of the coating, and meanwhile, the vacuum coating has the advantages of better compactness, high purity, uniform coating and the like, and in addition, the vacuum coating also has the advantages of good bonding strength with the flexible nonmetallic wire core 2, firm and high film and the like. The flexible nonmetal wire core 2 is a flexible rubber wire core, so that when the shielding wire 100 is wound on a shielded body, the surface of the shielding wire 100 is conveniently attached to the surface of the shielded body, and the shielding effect is improved.
In some examples, as shown in fig. 5, the number of the shielding units 1 is plural, and plural shielding units 1 include plural transverse units 11 and plural vertical units 12, and the plural transverse units 11 and the plural vertical units 12 are staggered to form a shielding net. The shielding net is formed by the staggered arrangement of the transverse units 11 and the vertical units 12, so that the material can be saved when the shielded body is paved or wrapped, and meanwhile, the shielding net is formed by the staggered arrangement of the transverse units 11 and the vertical units 12, so that the shielded body is wrapped when the shielded body is used conveniently.
In some examples, as shown in fig. 6, the shielding plating layer 3 includes an electromagnetic shielding layer 31 and a magnetic shielding layer 32; one part of the plurality of transverse units 11 is a first electromagnetic shielding unit 111 having the electromagnetic shielding layer 31, and the other part is a first magnetic shielding unit 112 having the magnetic shielding layer 32; one part of the plurality of vertical units 12 is a second electromagnetic shielding unit 121 having the electromagnetic shielding layer 31, and the other part is a second magnetic shielding unit 122 having the magnetic shielding layer 32. When the plurality of transverse units 11 and the plurality of vertical units 12 are staggered to form a shielding net, as one part of the transverse units 11 is the first electromagnetic shielding unit 111 with the electromagnetic shielding layer 31 and the other part is the first magnetic shielding unit 112 with the magnetic shielding layer 32, the transverse units 11 can respectively shield electromagnetic waves and electromagnetic fields, so that the transverse units 11 have better shielding effect. Similarly, when the plurality of transverse units 11 and the plurality of vertical units 12 are staggered to form a shielding net, as one part of the vertical units 12 is the second electromagnetic shielding unit 121 with the electromagnetic shielding layer 31 and the other part is the second magnetic shielding unit 122 with the magnetic shielding layer 32, the vertical units 12 can respectively shield electromagnetic waves and electromagnetic fields, so that the vertical units have better shielding effect.
In some examples, as shown in fig. 7, the shielding wire 100 further includes an insulation protection sleeve 4, and the first electromagnetic shielding units 111 and the first magnetic shielding units 112 are alternately arranged in the insulation protection sleeve 4; the second electromagnetic shielding units 121 and the second magnetic shielding units 122 are arranged in an alternating arrangement in the insulating protective sleeve 4. The first electromagnetic shielding units 111 and the first magnetic shielding units 112 are arranged in a staggered manner, so that the capability of the first electromagnetic shielding units 111 for shielding magnetic fields and the capability of the first electromagnetic shielding units 111 for shielding electromagnetic waves can be fully utilized.
