Description

Technical Field

[0001] This utility model relates to the technical field of wires and cables, specifically to a flat automatic take-up cable. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. They are mainly used for multiple functions such as control installation, equipment connection, and power transmission. Cables are divided into single-core cables and multi-core cables.

[0003] In the current use of multi-core cables, it is often necessary to split the cables, which requires the use of cable splitters. However, splitting multi-core cables poses significant safety hazards, and cable management during splitting often results in cable tangling and damage, increasing the safety risks during use. To address this issue and provide a safer cable splitting solution, we propose an automatic cable reel and management system. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a flat automatic cable retraction system, which solves the problem of cable misalignment often occurring during the sorting and separation of existing multi-core cables, causing damage to the multi-core cables and increasing safety hazards during use.

[0005] The technical solution adopted by this utility model is as follows: it includes a first signal core, a power supply core, a second signal core, and a flat outer sheath. The first signal core is centrally located on the flat outer sheath. Two sets of power supply cores are arranged symmetrically on the flat outer sheath with the first signal core as the center. The second signal core is symmetrically arranged on the flat outer sheath with the first signal core as the center, and the second signal core is located on one side of the power supply core. The upper and lower surfaces of the flat outer sheath are provided with winding grooves, and the winding grooves are located between the first signal core and the power supply core.

[0006] A further improvement to the above scheme is that the first signal core includes an inner conductor, an outer conductor, and a signal outer sheath, wherein the inner conductor and the outer conductor are both disposed inside the signal outer sheath, and the signal outer sheath is disposed on the flat outer sheath.

[0007] A further improvement to the above scheme is that multiple outer conductors are provided, and the multiple outer conductors are twisted together to cover the outer periphery of the inner conductor.

[0008] A further improvement to the above scheme is that the signal sheath is integrally extruded from polytetrafluoroethylene or polyimide to cover the inner conductor and the outer conductor.

[0009] A further improvement to the above scheme is that the power supply core includes a power conductor, an inner core insulation layer covering the outside of the power conductor, and an inner core shielding layer covering the outside of the inner core insulation layer.

[0010] A further improvement to the above scheme is that the inner core insulation layer and the inner core shielding layer are integrally extruded using polytetrafluoroethylene or polyimide.

[0011] A further improvement to the above scheme is that the inner core insulation layer is extruded and coated on the outside of the power conductor, and the inner core shielding layer is an aluminum foil layer.

[0012] A further improvement to the above solution is that the flat outer sheath is integrally injection molded.

[0013] A further improvement to the above scheme is that the winding groove is provided in two sets, and the two sets of winding grooves are symmetrically arranged.

[0014] A further improvement to the above solution is that the winding groove is a flexible groove.

[0015] The beneficial effects of this utility model are:

[0016] Compared to existing cables, this utility model ensures stable signal transmission through a centrally located first signal core; the two sets of power cores are symmetrically arranged around the first signal core, effectively providing a balanced power supply; the second signal core is also symmetrically arranged and located on one side of the power core, effectively enhancing signal processing capabilities; the cable winding grooves on the upper and lower sides of the flat outer sheath facilitate automatic cable winding, improving ease of use, practicality, and promising application prospects.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] like Figure 1-4As shown in the embodiment of this utility model, a flat automatic take-up cable includes a first signal inner core 10, a power inner core 20, a second signal inner core 30, and a flat outer sheath 40. The first signal inner core 10 is centrally located on the flat outer sheath 40. Two sets of power inner cores 20 are symmetrically arranged on the flat outer sheath 40 with the first signal inner core 10 as the center. The second signal inner core 30 is symmetrically arranged on the flat outer sheath 40 with the first signal inner core 10 as the center, and is located on one side of the power inner core 20. The flat outer sheath 40 has winding grooves 41 on its upper and lower surfaces, located between the first signal inner core 10 and the power inner core 20. In this embodiment, the first signal inner core 10 is precisely positioned at the center of the flat outer sheath 40, ensuring the stability and efficiency of signal transmission, reducing the possibility of signal attenuation and interference, optimizing the layout, and resulting in a compact structure. Secondly, the second signal core 30 is also symmetrically arranged around the first signal core 10, cleverly positioned on one side of the power core 20. This layout avoids direct interference between the signal and power lines and makes full use of the space in the flat outer sheath 40, improving data transmission capacity and speed. Thirdly, the flat outer sheath 40 has winding grooves 41 designed on its upper and lower surfaces, located between the first signal core 10 and the power core 20, providing a basis for automatic cable storage. This allows users to easily wind and store the cable through these grooves, greatly improving ease of use and cable neatness, while also reducing the risk of tangling and damage during carrying or storage; it is highly practical.

[0029] like Figure 1 As shown, the first signal core 10 includes an inner conductor 11, an outer conductor 12, and a signal sheath 13. Both the inner conductor 11 and the outer conductor 12 are disposed within the signal sheath 13, which is mounted on a flat outer sheath 40. In this embodiment, the first signal core 10, composed of the inner conductor 11, the outer conductor 12, and the signal sheath 13, is nested within the flat outer sheath 40, achieving effective signal transmission and protection. Simultaneously, the flat design facilitates automatic cable retraction and saves space.

[0030] Multiple outer conductors 12 are provided, and the multiple outer conductors 12 are twisted together and wrapped around the outer periphery of the inner conductor 11. In this embodiment, by twisting multiple outer conductors 12 together and wrapping around the outer periphery of the inner conductor 11, the structural stability and signal transmission performance of the cable are enhanced.

[0031] The signal sheath 13 is integrally extruded from polytetrafluoroethylene or polyimide to cover the inner conductor 11 and the outer conductor 12. In this embodiment, the signal sheath 13, integrally extruded from polytetrafluoroethylene or polyimide, effectively covers the inner conductor 11 and the outer conductor 12, achieving a compact structure and excellent insulation performance, ensuring the stability of signal transmission and the durability of the cable.

[0032] like Figures 3 to 4 As shown, the power supply core 20 includes a power conductor 21, an inner core insulation layer 22 covering the power conductor 21, and an inner core shielding layer 23 covering the inner core insulation layer 22. In this embodiment, the power conductor 21 provides efficient power transmission to the power supply core 20, ensuring the stability of the power supply. The inner core insulation layer 22 and the inner core shielding layer 23 effectively isolate the power conductor 21, reduce electromagnetic interference, prevent current leakage, and improve safety.

[0033] The inner core insulation layer 22 and the inner core shielding layer 23 are integrally extruded from polytetrafluoroethylene (PTFE) or polyimide. In this embodiment, integral extrusion improves the tightness of the bond between the inner core insulation layer 22 and the shielding layer, reducing the possibility of delamination or loosening, thereby improving the overall structural stability of the cable. Furthermore, PTFE and polyimide are both excellent insulating materials with outstanding electrical insulation properties, effectively isolating the inner conductor from the external environment, preventing current leakage or short circuits, and are highly practical.

[0034] The inner core insulation layer 22 is extruded and wrapped around the power conductor 21, and the inner core shielding layer 23 is an aluminum foil layer. In this embodiment, the inner core insulation layer 22 tightly wraps around the power conductor 21 through extrusion, effectively isolating electrical components and enhancing safety; the inner core shielding layer 23, made of aluminum foil, effectively shields electromagnetic interference and improves cable performance.

[0035] The flat outer sheath 40 is integrally injection molded. In this embodiment, by integrally injection molding the flat outer sheath 40, the cable structure is made compact and stable, improving the overall durability and aesthetics of the automatic cable retraction cable.

[0036] Two sets of cable winding grooves 41 are provided, and the two sets of cable winding grooves 41 are symmetrically arranged. In this embodiment, by providing two sets of symmetrical cable winding grooves 41, the flat automatic cable winding cable can achieve more balanced and stable cable winding and unwinding, improving ease of use and efficiency.

[0037] The cable winding groove 41 is a flexible groove. In this embodiment, the flexible design of the cable winding groove 41 effectively improves the storage efficiency and flexibility of the flat automatic cable winding.

[0038] In an embodiment of this utility model, a flat automatic take-up cable includes a first signal inner core 10, a power inner core 20, a second signal inner core 30, and a flat outer sheath 40. The first signal inner core 10 is centrally located on the flat outer sheath 40. Two sets of power inner cores 20 are symmetrically arranged on the flat outer sheath 40 with the first signal inner core 10 as the center. The second signal inner cores 30 are symmetrically arranged on the flat outer sheath 40 with the first signal inner core 10 as the center, and the second signal inner cores 30 are located on one side of the power inner cores 20. The flat outer sheath 40 is positioned vertically and horizontally. The cable has winding grooves 41 on both sides, which are located between the first signal core 10 and the power core 20. The centrally located first signal core 10 ensures stable signal transmission. The two sets of power cores 20 are symmetrically arranged with the first signal core 10 as the center, effectively providing a balanced power supply. The second signal core 30 is also symmetrically arranged and located on one side of the power core 20, effectively enhancing signal processing capabilities. The design of winding grooves 41 on the upper and lower sides of the flat outer sheath 40 facilitates automatic cable winding, improves ease of use, and has strong practicality and good application prospects.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
