Description

Technical Field

[0001] The utility model relates to the field of electronic wires, in particular to a double-layer insulated electronic wire. Background Art

[0002] Electronic wire is a short name for the internal wires of electrical equipment. Its electrical conductivity is mainly weak current, which is a different concept from cables in the strong current category.

[0003] Existing electronic wires are usually composed of a core wire and a protective outer layer wrapped around it. During use, they are often dragged, and the protective outer layer of the electronic wire will directly rub against the ground or contact surface. After a period of use, the protective outer layer will be worn or even worn out, exposing the core wire inside. When the protective outer layer is damaged, the protective performance is greatly reduced, causing the core wire to be prone to short circuits and other phenomena, thereby reducing the service life of the electronic wire. In addition, during use, it will also be affected by various external pressures, bending and stretching, and the core wire inside is easily squeezed and cracked, causing the core wire to break. The protective outer layer with a single structure is relatively soft and has low mechanical strength, and cannot make the electronic wire resistant to bending and stretching, which easily causes the electronic wire to break, greatly reducing its service life. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technical solutions, the utility model provides a double-layer insulated electronic wire, which can effectively solve the technical problems that the existing electronic wire has low mechanical strength, resulting in easy breakage of the electronic wire, and has only one layer of protective outer jacket to protect the electronic wire, resulting in poor protection performance.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a double-layer insulated electronic wire, including a core body, the outer surface of the core body is wrapped with a first insulating layer, the outer surface of the first insulating layer is surrounded by a metal wire, the outer surface of the metal wire is wrapped with a metal shielding layer, the outer surface of the metal shielding layer is wrapped with a reinforcement layer, the outer surface of the reinforcement layer is provided with a plurality of steel strips, the plurality of steel strips extend along the length direction of the reinforcement layer, the surface of the steel strips is wrapped with a second insulating layer, and the outer surface of the second insulating layer is wrapped with a third insulating layer.

[0006] Furthermore, the core is composed of tinned copper wire.

[0007] Furthermore, the first insulating layer, the second insulating layer and the third insulating layer are all made of improved polyvinyl chloride material.

[0008] Furthermore, the reinforcement layer is made of rubber material.

[0009] Furthermore, the thickness of the second insulating layer is smaller than the thickness of the third insulating layer.

[0010] Compared with the existing technology, the beneficial effects of the present invention are: the double-layer insulated electronic wire of the present invention can effectively enhance the mechanical strength of the electronic wire by wrapping metal wire, reinforcement layer and steel belt on the surface of the core, preventing the electronic wire from breaking during use such as bending and stretching. By setting a double-layer structure of the second insulating layer and the third insulating layer, the double protection of the core is greatly improved. When the third insulating layer is damaged, the second insulating layer can still play a protective role. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1-Figure 3As shown, a double-layer insulated electronic wire comprises a core 1, the outer surface of the core 1 is wrapped with a first insulating layer 2, the outer surface of the first insulating layer 2 is surrounded by a metal wire 3, the outer surface of the metal wire 3 is wrapped with a metal shielding layer 4, and the metal shielding function is achieved by setting the metal shielding layer 4, which can prevent the electronic wire from electromagnetic interference, and improve the stability and anti-interference ability of signal transmission by the metal shielding layer 4. The outer surface of the metal shielding layer 4 is wrapped with a reinforcement layer 5, and the outer surface of the reinforcement layer 5 is provided with a plurality of steel belts 6, which extend along the length direction of the reinforcement layer 5, and the surface of the steel belt 6 is wrapped with a plurality of steel belts 6. It is wrapped with a second insulating layer 7, and the outer surface of the second insulating layer 7 is wrapped with a third insulating layer 8. The core 1 is composed of tinned copper wire, and the first insulating layer 2, the second insulating layer 7 and the third insulating layer 8 are all composed of improved polyvinyl chloride material. The reinforcing layer 5 is composed of rubber material. The thickness of the second insulating layer 7 is less than the thickness of the third insulating layer 8. This design optimizes the overall structure and performance of the electronic wire by adjusting the thickness of the insulating layer while ensuring sufficient insulation performance. The thinner second insulating layer 7 can reduce material cost, while the thicker third insulating layer 8 can provide better external protection and wear resistance.

[0018] The double-layer insulated electronic wire of this embodiment can effectively enhance the mechanical strength of the electronic wire by wrapping the metal wire 3, the reinforcement layer 5 and the steel belt 6 on the surface of the core 1, thereby preventing the electronic wire from breaking during use such as bending and stretching. By setting a double-layer structure of the second insulating layer 7 and the third insulating layer 8, the dual protection of the core 1 is greatly improved. When the third insulating layer 8 is damaged, the second insulating layer 7 can still play a protective role.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description.
