Description

Technical Field

[0001] The invention belongs to the technical field of UL electronic wires, and in particular relates to a UL electronic wire with resistant breakage. Background Art

[0002] UL electronic wires are electronic wires that meet the environmental protection requirements of the EU ROHS standard and are generally suitable for weak current projects, such as internal wiring of electronic and electrical equipment. UL is the most authoritative in the United States and the largest private institution in the world engaged in safety testing and appraisal. Its certification standards have a wide influence in the electronics industry. UL electronic wires have been strictly tested and verified by UL and are considered to be safe and reliable products. Its physical properties, chemical properties, and electrical properties all meet the relevant standards, ensuring safe use in various environments.

[0003] When UL electronic wires are wound around, the outer walls of both sides of the wire body will directly contact each other. This close contact state will cause the heat dissipation performance of the outer walls of the contact ends to affect each other during the long-term use of UL electronic wires. Specifically, when a UL electronic wire is transmitting current, it will generate a certain amount of heat. If there are other UL electronic wires in close contact around it at this time, then this heat will be transferred to the adjacent wire body through the contact surface. If this heat transfer cannot be effectively dissipated, it will cause the temperature of the wire body to rise, thereby affecting its electrical performance and insulation performance.

[0004] If the UL electronic wire is exposed to such high temperature for a long time, the insulation layer may age faster, become fragile and easy to crack, and may even cause safety hazards such as short circuit and leakage. In addition, high temperature will accelerate the oxidation and corrosion of the metal conductor in the wire body, thereby reducing the conductive performance of the conductor, further affecting the service life and reliability of the UL electronic wire. Summary of the invention

[0005] The purpose of the present invention is to provide a UL electronic wire with anti-breakage, which aims to solve the problem that when a UL electronic wire transmits current, a certain amount of heat will be generated. If there are other UL electronic wires in close contact with it at this time, the heat will be transferred to the adjacent wire body through the contact surface. If this heat transfer cannot be effectively dissipated, it will cause the temperature of the wire body to rise, thereby affecting its electrical performance and insulation performance.

[0006] To achieve the above object, the present invention provides the following technical solution: a UL electronic wire with folding resistance, comprising a UL electronic wire, a circle of filling layer is arranged inside the UL electronic wire, a circle of folding resistance layer is arranged between the filling layer and the UL electronic wire, and a spacer is connected to the outer wall of one side of the UL electronic wire; A fitting strip is connected to the outer wall of the UL electronic wire on one side away from the partition strip, a snap-fit ​​strip is connected to the top corner of one side of the fitting strip, a group of force-bearing columns are installed at equal intervals on the upper surface of the UL electronic wire, and a pressure plate is arranged inside the force-bearing columns.

[0007] In order to ensure that the outer walls on both sides of the UL electronic wire can maintain a certain distance when the UL electronic wire is rolled up, as a preferred UL electronic wire with resistance to breakage in the present invention, two partition bars are symmetrically installed on one side of the UL electronic wire, and the outer wall of the partition bar away from the UL electronic wire is an arc-shaped structure, and the arc formed between the two partition bars is adapted to the arc of the outer wall of the UL electronic wire.

[0008] In order to form a stable side docking structure through this structure when the UL electronic wire is rolled up, as a preferred UL electronic wire with resistant breakage of the present invention, an inner wall opening is opened on the arc-shaped outer wall of the partition bar, and an extension groove is opened inside the partition bar, and the opening of the extension groove is connected to the inner wall opening. The embedding strip and the clamping strip are at the same level as the inner wall opening and the extension groove, and the embedding strip and the clamping strip are embedded and docked with the inner wall opening and the extension groove when the UL electronic wire is wound around and rolled up.

[0009] In order to weaken the superimposed pressure of the UL electronic wire when the multiple layers are rolled up inside the stress column, as a preferred UL electronic wire with resistant breakage of the present invention, a group of guide strips are symmetrically installed on the inner wall of the stress column, and a triangular plate is fixedly installed on the bottom wall of the inner cavity of the stress column, and the outer wall of one side of the triangular plate is in active contact with the outer wall of one side of the diagonal support rod. The bottom of the diagonal support rod is fixedly installed on the inner wall of the stress column, and the diagonal support rod is made of hard rubber, and the angle between the diagonal support rod and the stress column is 60°.

[0010] In order to enable the pressure plate to move downward inside the stress column with a fixed track, as a preferred UL electronic wire with resistant breakage of the present invention, the central end surface of the pressure plate is fixedly connected with a docking column, a notch is respectively opened on both sides of the pressure plate, and two flexible rubber columns are symmetrically installed at the bottom of the pressure plate. The top of the docking column is fixedly connected to the inner wall of the upper end of the stress column, and each of the notches is movably connected to the outer wall of a guide strip.

[0011] In order to prevent the pressure during multi-layer winding of the UL electronic wire from squeezing the elastic strip to a horizontal state, so that the elastic strip can automatically reset when the pressure is removed, a preferred UL electronic wire with resistance to breakage of the present invention is provided with an elastic strip installed on the inner wall of the bottom end of the force-bearing column, and the side structure of the elastic strip is a C-shaped structure. The two diagonal braces are located at the bottom of the elastic strip, and the maximum vertical height of the diagonal braces is equal to two-thirds of the maximum vertical height of the elastic strip.

[0012] Compared with the prior art, the present invention has the following beneficial effects: A section of UL electronic wire is usually reserved when it is used. When winding up this reserved section of UL electronic wire, the operation is as follows: first, place the two rolls of UL electronic wire after one circle with their sides facing each other; then, dock the spacers on both sides of the UL electronic wire with the interlocking strips and the snap-fit ​​strips. After docking, a certain gap will be maintained between the two or more wrapped rolls of UL electronic wire, which can effectively ensure the heat dissipation effect of the outer wall of the UL electronic wire when in use. At the same time, the docking between the spacers and the interlocking strips and the snap-fit ​​strips can also improve the neatness of the UL electronic wire when it is rolled up; In addition, stress-bearing columns are arranged at equal intervals on the surface of the UL electronic wire. When the UL electronic wire is superimposed and wound, these stress-bearing columns can weaken the pressure on the UL electronic wire during extrusion through the elastic strips inside them. The specific principle is: when the stress-bearing column is deformed under pressure, it will drive the pressure plate to move downward; when the pressure plate moves downward, it will squeeze the elastic strip. At this time, under the elastic effect of the elastic strip, the extrusion impact force will be slowed down, thereby reducing the huge pressure impact brought by the instantaneous pressure to the UL electronic wire. This can improve the safety of the UL electronic wire when it is rolled up. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-7 The present invention provides the following technical solutions: a UL electronic wire with folding resistance, including a UL electronic wire 1, a circle of filling layer 2 is arranged inside the UL electronic wire 1, a circle of folding-resistant layer 3 is arranged between the filling layer 2 and the UL electronic wire 1, and the folding-resistant layer 3 is composed of a steel wire mesh, a resin coating, a spring steel wire and a nylon layer. The steel wire mesh strengthens the overall fastness of the UL electronic wire 1, and multiple spring steel wires wrap the UL electronic wire 1, so that the UL electronic wire 1 has the ability to resist breaking. The folding-resistant layer 3 is a mature technology of the existing patent. For details, please refer to the application number: 2020229768763; A partition bar 4 is connected to the outer wall of one side of the UL electronic wire 1, a fitting bar 5 is connected to the outer wall of the side of the UL electronic wire 1 away from the partition bar 4, a snap-fit ​​bar 6 is connected to the top corner of one side of the fitting bar 5, and a group of force-bearing columns 7 are installed at equal intervals on the upper surface of the UL electronic wire 1, and a pressure plate 8 is arranged inside the force-bearing columns 7.

[0017] Preferably: two spacers 4 are symmetrically installed on one side of the UL electronic wire 1, and the outer wall of the spacer 4 on the side away from the UL electronic wire 1 is an arc-shaped structure, and the arc formed between the two spacers 4 is adapted to the arc of the outer wall of the UL electronic wire 1. An inner wall opening 401 is provided on the arc-shaped outer wall of the spacer 4, and an extension groove 402 is provided inside the spacer 4, and the opening of the extension groove 402 is connected to the inner wall opening 401. The interlocking strip 5 and the snap-fitting strip 6 are located at the same horizontal height as the inner wall opening 401 and the extension groove 402, and the interlocking strip 5 and the snap-fitting strip 6 are interlocked and docked with the inner wall opening 401 and the extension groove 402 when the UL electronic wire 1 is wound and rolled up.

[0018] When used specifically, in order to ensure the convenience of connection and storage of the UL electronic wire 1 in actual application, a section of unused length is usually reserved in advance. This reserved section of UL electronic wire 1 not only provides material preparation for possible future connection or extension, but also facilitates flexible winding management when needed. When it is necessary to orderly wind and store this reserved section of UL electronic wire 1, the specific operation steps are meticulous and efficient.

[0019] First, the operator will properly place the two rolls of UL electronic wire 1 that have been wound around in a circle in a side-to-side manner to ensure that they can be tightly and neatly arranged together, laying a good foundation for the subsequent docking steps. Then, the pre-designed spacer strips 4, interlocking strips 5 and snap-fit ​​strips 6 on both sides of the UL electronic wire 1 are used to perform precise docking operations. This not only enhances the connection stability between the UL electronic wires 1, but also ensures the close connection between the rolls during the winding process, avoiding looseness or scattering.

[0020] After the docking is completed, a certain gap will naturally form and maintain between the two or more coils of UL electronic wire 1. This design solves the heat dissipation problem that may occur during long-term use or storage. By maintaining an appropriate gap, it can ensure that the outer wall of the UL electronic wire 1 can effectively dissipate heat during use, avoiding performance degradation or safety hazards caused by overheating.

[0021] In addition, the clever connection between the spacer strip 4, the interlocking strip 5 and the snap-fit ​​strip 6 not only improves the neatness of the UL electronic wire 1 when it is rolled up, but also makes the entire rolling process more efficient and orderly. This design not only optimizes the utilization of the storage space, but also enables the UL electronic wire 1 to be quickly unfolded when needed, greatly improving work efficiency and ease of use.

[0022] Preferably: a group of guide strips 701 are symmetrically mounted on the inner wall of the force-bearing column 7, the force-bearing column 7 is made of flexible rubber material, a triangular plate 702 is fixedly mounted on the bottom wall of the inner cavity of the force-bearing column 7, and one side outer wall of the triangular plate 702 is in active contact with one side outer wall of the diagonal support rod 703. The bottom of the diagonal support rod 703 is fixedly mounted on the inner wall of the force-bearing column 7, the diagonal support rod 703 is made of hard rubber material, and the angle between the diagonal support rod 703 and the force-bearing column 7 is 60°; An elastic strip 9 is installed on the inner wall of the bottom end of the load-bearing column 7. The side structure of the elastic strip 9 is a C-shaped structure. Two diagonal support rods 703 are located at the bottom of the elastic strip 9, and the maximum vertical height of the diagonal support rods 703 is equal to two-thirds of the maximum vertical height of the elastic strip 9.

[0023] When used, the UL electronic wire 1 is designed with equally spaced stress columns 7 on its surface, which is designed to optimize the pressure distribution during the overlapping winding process. When multiple UL electronic wires 1 need to be tightly and safely rolled together, these stress columns 7 play an important role. The elastic strips 9 inside them are the core of this mechanism, and by utilizing the elastic properties of the material, effective pressure relief is achieved.

[0024] Specifically, when the force-bearing column 7 is deformed by external compression, the deformation will further drive the pressure plate 8 connected thereto to move downward along a predetermined path. As the pressure plate 8 is gradually pressed downward, it will exert a gradually increasing pressure on the internal elastic strip 9. The elastic strip 9 can effectively absorb and disperse this pressure by virtue of its elastic recovery ability, thereby alleviating the direct impact force of external compression on the UL electronic wire 1 body.

[0025] This process not only significantly reduces the risk of damage to the UL electronic wire 1 caused by instantaneous pressure, but also ensures that the electronic wire can maintain its original structural integrity and electrical performance during the entire winding process. Therefore, this design not only improves the safety of the UL electronic wire 1 during winding, but also extends its service life, providing users with a more reliable and efficient electronic wire solution.

[0026] Preferably, a docking column 801 is fixedly connected to the central end surface of the pressing plate 8, a notch 802 is respectively provided on both sides of the pressing plate 8, and two flexible rubber columns 803 are symmetrically installed at the bottom of the pressing plate 8. The flexible rubber columns 803 are hollow in structure and can be squeezed and deformed. The top of the docking column 801 is fixedly connected to the inner wall of the upper end of the force-bearing column 7, and each notch 802 is movably connected to the outer wall of a guide strip 701.

[0027] When in use, when the force-bearing column 7 is compressed, it will drive the pressure plate 8 to move downward through the docking column 801. When the pressure plate 8 moves, the notches 802 on both sides will move along the track of the corresponding guide strip 701. At the same time, when the pressure plate 8 moves, the two flexible rubber columns 803 at the bottom will also move toward the bottom. When the pressure plate 8 continues to move downward, the bottom of the flexible rubber column 803 will be squeezed with the inner wall of the force-bearing column 7. At this time, the flexible rubber column 803 will be deformed, which can further slow down the downward movement speed of the pressure plate 8.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
