Description

Technical Field

[0001] The utility model relates to the technical field of electronic wires, in particular to a tensile-resistant UL electronic wire. Background Art

[0002] Today, UL electronic wire is a general term for electronic wires that have passed UL certification. It is an electronic wire that meets the environmental protection requirements under the EU ROHS standard. It is generally used in weak current projects, such as internal connections of electronic and electrical equipment. With the development of science and technology, electronic appliances are becoming more and more popular, and the production and use of electronic wires are increasing year by year.

[0003] Currently, the UL electronic wires on the market are all simple single-group wire harnesses, or multiple groups of wires that are glued together. The outside is protected by a single layer of plastic. However, when using the electronic wires, the wire groups often need to be combed and stretched to make the wiring neater and clearer. However, the protective effect of the above structure is limited. During the process of winding and unwinding the wires, the electronic wires are easily stretched and bent, which can cause the electronic wires to deform. In severe cases, it can even cause the internal conductive wires to break, resulting in the interruption of data transmission within the device, seriously affecting the use of the device. Utility Model Content

[0004] The purpose of the present invention is to provide a tensile-resistant UL electronic wire to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: a tensile-resistant UL electronic wire, comprising a core wire, an elastic layer is provided on the surface of the core wire, an insulating layer is provided on the surface of the elastic layer, an inner protective layer is provided on the surface of the insulating layer, a plurality of tensile-resistant strips are embedded in the inner protective layer along the circumferential direction, and a wear-resistant protective layer is provided on the surface of the inner protective layer.

[0006] Using the above technical solution, the elastic layer wraps the core wire. When subjected to tensile force, the elastic layer has strong tensile resistance, and the deformation will offset the tensile force, thereby protecting the core wire from being broken. The extension direction of the anti-tensile strip is the same as the extension direction of the wire core, which effectively improves the overall tensile strength of the electronic wire, thereby further protecting the wire core from being broken. The wear-resistant protective layer has good wear resistance and a thicker thickness, wrapping the core wire and other internal structures to protect them.

[0007] As a further optimization of the present invention, the wear-resistant protective layer is provided with several mounting rings at intervals along the length direction, and a reset spring is fixed between every two adjacent mounting rings. The reset spring is sleeved on the outside of the wear-resistant protective layer, and the reset spring is in a no-load state.

[0008] Using the above technical solution, multiple reset springs are connected and sleeved on the outside of the electronic wire through the mounting ring. Under normal circumstances, the reset spring is in a no-load state; when the electronic wire is bent, the reset spring also bends and deforms, and the reset spring generates elastic potential energy to automatically reset, thereby driving the electronic wire to reset and straighten again. When the electronic wire is stretched or squeezed, the reset spring also produces the same deformation, and the reset spring generates elastic potential energy to automatically reset, thereby driving the electronic wire to reset and straighten again, realizing the correct reset of the electronic wire, reducing the deformation or breakage of the electronic wire due to continuous external force, and further increasing the protection of the core wire.

[0009] As a further optimization of the present invention, the elastic layer is a plurality of bulletproof wires spirally twisted with the core wire.

[0010] By adopting the above technical solution, the bulletproof wire has a strong tensile performance. The bulletproof wire fixes the core wire well, making it difficult to move and having better stability, thereby increasing the tensile resistance of the core wire.

[0011] As a further optimization of the present invention, the anti-stretching strip is made of glass fiber cloth.

[0012] By adopting the above technical solution, the strength of the glass fiber cloth is mainly in the warp and weft directions of the fabric, and it has high tensile strength in both the warp and weft directions, thereby improving the overall tensile strength of the electronic wire.

[0013] As a further optimization of the present invention, the outer wall of the wear-resistant protective layer is provided with a plurality of slots at equal intervals along the circumferential direction, and the inner wall of the mounting ring is provided with a card block corresponding to the plurality of slots one by one, and the card block is plugged and fixed to the slot.

[0014] As a further optimization of the present invention, a reinforcement frame is provided on the inner wall of the card slot, the reinforcement frame is made of hard plastic, and the card block is connected to the reinforcement frame by gluing.

[0015] By adopting the above technical solution, the reinforcement frame can prevent the card slot from being deformed due to force and affecting the connection between the card slot and the card block.

[0016] The beneficial effects of the present invention are as follows: the elastic layer wraps the core wire, and when subjected to tensile force, the elastic layer has a strong tensile resistance, and the deformation will offset the tensile force, thereby protecting the core wire from being broken. The extension direction of the anti-tensile strip is the same as the extension direction of the wire core, which effectively improves the overall tensile strength of the electronic wire, thereby further protecting the wire core from being broken. The wear-resistant protective layer has good wear resistance and a thicker thickness, and wraps the core wire and other internal structures to protect them. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See attached Figure 1-2 The embodiment disclosed in the present utility model further provides: a tensile-resistant UL electronic wire, comprising a core wire 1, an elastic layer 2 being provided on the surface of the core wire 1, specifically, the elastic layer 2 being a plurality of bulletproof wires spirally twisted with the core wire 1;

[0022] An insulating layer 3 is provided on the surface of the elastic layer 2, and an inner protective layer 4 is provided on the surface of the insulating layer 3. A plurality of anti-stretching strips 5 are embedded in the inner protective layer 4 along the circumferential direction. Specifically, the anti-stretching strips 5 are made of glass fiber cloth. A wear-resistant protective layer 6 is provided on the surface of the inner protective layer 4.

[0023] The wear-resistant protective layer 6 is provided with a plurality of mounting rings 7 at intervals along the length direction. Specifically, the outer wall of the wear-resistant protective layer 6 is provided with a plurality of card grooves 61 at equal intervals along the circumferential direction. The inner wall of the mounting ring 7 is provided with a card block 71 corresponding to the plurality of card grooves 61. The card block 71 is plugged and fixed to the card groove 61. The inner wall of the card groove 61 is provided with a reinforcement frame 8. The reinforcement frame 8 is made of hard plastic. The card block 71 is connected to the reinforcement frame 8 by gluing.

[0024] A return spring 9 is fixed between every two adjacent mounting rings 7 . The return spring 9 is sleeved on the outside of the wear-resistant protective layer 6 . The return spring 9 is in a no-load state.

[0025] The principle of the utility model is as follows: the elastic layer 2 wraps the core wire 1, and the bulletproof wire has strong tensile resistance. The bulletproof wire fixes the core wire 1 well, making it difficult to move and more stable, thereby increasing the tensile resistance of the core wire 1. When subjected to a tensile force, the bulletproof wire deforms to offset the tensile force, thereby protecting the core wire 1 from being broken;

[0026] The extension direction of the tensile strip 5 is the same as that of the wire core. The strength of the glass fiber cloth is mainly in the warp and weft directions of the fabric. It has high tensile strength in both the warp and weft directions, thereby improving the overall tensile strength of the electronic wire, thereby further protecting the wire core from being broken. The wear-resistant protective layer 6 has good wear resistance and a thick thickness, wrapping the core wire 1 and other internal structures to protect them.

[0027] Multiple reset springs 9 are connected and sleeved on the outside of the electronic wire through the mounting ring 7. Under normal circumstances, the reset spring 9 is in a no-load state; when the electronic wire is bent, the reset spring 9 also produces a bending deformation, and the reset spring 9 generates elastic potential energy to automatically reset, thereby driving the electronic wire to reset and straighten again. When the electronic wire is stretched or squeezed, the reset spring 9 also produces the same deformation, and the reset spring 9 generates elastic potential energy to automatically reset, thereby driving the electronic wire to reset and straighten again, realizing the correction and reset of the electronic wire, reducing the deformation or breakage of the electronic wire due to continuous external force, and further increasing the protection of the core wire 1.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
