Description

Technical Field

[0001] This utility model relates to data cable technology, and more particularly to a data cable that is resistant to bending and tensile stress. Background Technology

[0002] A data cable is an electronic connection used to transmit data and power. The performance of a data cable is closely related to its materials. The conductor is usually made of copper because copper has good conductivity and relatively low cost, while the outer sheath material needs to be wear-resistant, bend-resistant, and insulating.

[0003] A search revealed Chinese Patent Publication No. CN202420611757.3, which discloses a cable and its data cable. The cable includes a sheathing layer, a core, and a first filler for enhancing structural strength; the core is sheathed within the sheathing layer. The core includes a first core wire and a second core wire, both of which are sheathed with conductors. The first filler is filled within the first and second core wires. The cable of this invention uses a first filler to enhance the structural strength of the first and second core wires, thereby increasing the overall structural strength of the cable and improving its service life.

[0004] While existing data cables have enhanced overall structural strength to extend their lifespan, their lifespan is often affected by external environmental factors during actual use. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bending and tensile resistant data cable, which aims to improve the problem of data cables being damaged by external environmental temperature and oil stains.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending and tensile resistant data cable, comprising multiple conductors, a tensile skeleton provided between the multiple conductors, an inner insulation layer fixedly connected to the surface of each of the multiple conductors, a reinforcing braided layer provided on the outside of the multiple conductors, a filler provided inside the reinforcing braided layer, an aluminum foil Mylar tape provided on the outer surface of the reinforcing braided layer, an elastic nylon thread provided on the outer surface of the aluminum foil Mylar tape, a flame-retardant buffer layer provided on the outside of the elastic nylon thread, an outer sheath provided on the outer surface of the flame-retardant buffer layer, connectors provided at both ends of the outer sheath, and connecting components provided between each of the two connectors and the outer sheath.

[0007] Through the above technical solutions: the conductor adopts a multi-strand stranding method, which can disperse the stress generated during bending, reduce the probability of metal fatigue, and ensure long-term stable conductivity. The inner insulation layer is made of a specific material, which, while achieving insulation function, can protect the conductor and withstand bending itself due to its resistance to high and low temperatures and high elasticity. The central tensile skeleton is the key to enhancing the overall tensile strength. Through reasonable layout, it bears the main tensile force. The reinforced braided layer gathers the internal structure, reduces the damage to the internal structure caused by external friction, and further improves the tensile strength. The filler fills the gaps to avoid breakage caused by mutual friction between internal components. The aluminum foil Mylar tape plays a role in shielding electromagnetic interference, while the elastic nylon wire helps to improve the bending resistance. The outer flame-retardant buffer layer and outer sheath provide flame-retardant protection, and the material selection of the outer sheath effectively copes with external oil stains and chemical corrosion.

[0008] As a further description of the above technical solution:

[0009] The connecting assembly includes a first connecting sleeve, which is fixedly connected to the connector and the outer sheath. A plurality of metal spring skeletons are provided between the first connecting sleeve and the outer sheath. The outer sheath has an annular cross-section, and the plurality of metal spring skeletons are annularly wrapped around the outer surface of the outer sheath. All of the plurality of metal spring skeletons are fixedly connected to the first connecting sleeve.

[0010] The above technical solution involves a connecting sleeve fixed between the connector and the outer sheath. Its shape adopts a gradually curved design, replacing right-angle bends. This allows stress generated during bending to be dispersed along the arc, preventing stress concentration at a single point and reducing the risk of breakage. Multiple metal spring clips are arranged in a ring around the outer sheath and fixed to the connecting sleeve. This layout allows the connection to maintain a certain degree of flexibility while resisting repeated bending. For data cables with round outer sheaths, this structural design of the connecting component specifically addresses the problem of easy breakage at the connection between the connector and the cable body. By dispersing stress and enhancing bending resistance, the overall lifespan of the data cable is improved.

[0011] As a further description of the above technical solution:

[0012] The connecting assembly includes a second connecting sleeve, which is fixedly connected to the connector and the outer sheath. A steel frame is provided between the second connecting sleeve and the outer sheath. The outer surface of the outer sheath is quadrilateral, and the top of the outer sheath is provided with a diagonal anti-slip groove. The steel frame is a rounded three-dimensional square.

[0013] The above technical solution addresses the following: For square data cables, the connecting components are designed to fit their shape. The connector sleeve is fixed between the connector and the outer sheath, employing a double-layer stepped structure. By increasing the local thickness, the bending resistance of the connection area is improved, adapting to bending scenarios in daily use. The steel frame between the connector sleeve and the outer sheath, in the shape of a rounded three-dimensional square frame, enhances the tensile strength of the transition area between the connector and the cable body, making it suitable for environments with frequent plugging and unplugging, reducing damage caused by the force of plugging and unplugging. The diagonal anti-slip grooves on the outer surface of the outer sheath not only help improve heat dissipation and facilitate differentiation of the correct orientation, but also allow adhering oil and dirt to drain along the grooves, keeping the cable surface clean.

[0014] As a further description of the above technical solution:

[0015] The conductor is composed of multiple strands twisted together to form a composite flexible structure.

[0016] The above technical solution uses a multi-strand stranded conductor to form a composite flexible structure. This design can disperse the stress during bending, making it more adaptable to repeated bending than single-strand hard copper, reducing damage, ensuring stability during use, and improving durability.

[0017] As a further description of the above technical solution:

[0018] The tensile skeleton is located between multiple conductors to enhance the overall tensile strength.

[0019] The above technical solution utilizes a tensile-resistant skeleton positioned between multiple conductors, which is a key structure for enhancing the overall tensile strength of the data cable. Its location ensures that the stress is evenly distributed among the conductors, preventing damage from excessive localized stress.

[0020] As a further description of the above technical solution:

[0021] The elastic nylon thread is spirally wound around the outer surface of the aluminum foil Mylar tape, and the elastic nylon thread is tightly bonded to the aluminum foil Mylar tape and the flame-retardant buffer layer.

[0022] Through the above technical solution: the elastic nylon thread is spirally wound around the outer surface of the aluminum foil Mylar tape, and is closely attached to the aluminum foil Mylar tape and the flame-retardant buffer layer. This winding method allows it to work with the internal tensile skeleton to form a protective system from the inside out, improving the bending and tensile resistance. The close fit enhances the overall structure and allows the external force to be more evenly distributed, reducing local damage.

[0023] As a further description of the above technical solution:

[0024] The first connecting sleeve has a gradually curved outer shape, and the outer surface of the first connecting sleeve is provided with a diamond-shaped raised texture.

[0025] Through the above technical solution: the outer surface of the first connecting sleeve is a gradually curved shape, which can distribute the force between the wire and the connector when bending, reducing the risk of local damage. The diamond-shaped raised texture on its outer surface can increase the friction during insertion and removal, reducing the damage to the wire caused by excessive pulling.

[0026] As a further description of the above technical solution:

[0027] The second connecting sleeve has a double-layered stepped structure on the outside.

[0028] Through the above technical solution: the outer part of the second connecting sleeve has a double-layer stepped structure. By increasing the local thickness, the bending resistance is improved. When bending, the stepped shape can disperse the bending angle, reduce the direct bending degree between the wire and the connector, and reduce the possibility of breakage due to bending at the joint.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the conductor adopts a multi-strand stranded design, which can disperse bending stress. The central tensile skeleton can distribute tensile force, the reinforced braided layer further improves the tensile effect, and the elastic nylon thread helps to enhance the bending resistance. These structures work together to make the data cable less prone to damage during repeated bending and pulling, extend its service life, and solve the problem of data cable damage caused by external environmental temperature and oil stains.

[0031] 2. In this utility model, the outer sheath material can resist oil stains and chemical corrosion, and the flame-retardant buffer layer provides flame-retardant protection; the connecting component disperses bending stress through a gradual arc shape, and the internal skeleton enhances the bending and tensile strength of the connecting part, reducing the occurrence of connection point breakage, improving reliability, and solving the problem that the part of the data cable connected to the connector is prone to breakage during use.

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Example 1:

[0041] Reference Figures 1-3 A bending and tensile resistant data cable includes multiple conductors 1, a tensile skeleton 2 between the multiple conductors 1, an inner insulation layer 3 fixedly connected to the surface of each of the multiple conductors 1, a reinforcing braided layer 4 on the outside of the multiple conductors 1, a filler 5 inside the reinforcing braided layer 4, an aluminum foil Mylar tape 6 on the outer surface of the reinforcing braided layer 4, an elastic nylon wire 7 on the outer surface of the aluminum foil Mylar tape 6, a flame-retardant buffer layer 8 on the outside of the elastic nylon wire 7, an outer sheath 10 on the outer surface of the flame-retardant buffer layer 8, a connector 11 at both ends of the outer sheath 10, and a connecting component 9 between each connector 11 and the outer sheath 10.

[0042] Specifically, conductor 1 uses multi-strand twisted enameled copper to reduce metal fatigue when the data cable is bent during use, thus maintaining the stability of conductor 1 after bending. Each conductor 1 has an inner insulation layer 3 on its outer surface, made of flame-retardant TPU. This layer insulates conductor 1 while also being resistant to bending due to its high and low temperature resistance and high elasticity. A tensile skeleton 2 is placed at the center of the data cable to increase its tensile strength. The conductor 1, tensile skeleton 2, and inner insulation layer 3 are all bound together by a reinforcing braided layer 4, which is composed of a high-density nylon braided mesh to further enhance the tensile strength of the data cable. To reduce the damage to the internal structure caused by external friction, the gaps between the reinforcing braid layer 4, the tensile skeleton 2, and the inner insulation layer 3 are filled with filler 5 to prevent breakage caused by friction between multiple tensile skeletons 2. Then, an aluminum foil Mylar tape 6 and an elastic nylon wire 7 are set outside the reinforcing braid layer 4 to shield the data cable from electromagnetic interference and further improve its bending resistance. Finally, a flame-retardant buffer layer 8 and an outer sheath 10 are set on the outermost layer to provide flame retardancy to the data cable. The outer sheath 10 uses hydrogenated nitrile rubber to improve the oil and chemical corrosion resistance of the data cable, thereby achieving external protection for the data cable and solving the problem of damage to the data cable caused by external environmental temperature and oil.

[0043] Reference Figures 1-3 The connecting component 9 includes a first connecting sleeve 9101, which is fixedly connected to the connector 11 and the outer sheath 10. A plurality of metal spring skeletons 9102 are provided between the first connecting sleeve 9101 and the outer sheath 10. The outer sheath 10 has an annular cross-section, and the plurality of metal spring skeletons 9102 are annularly wrapped around the outer surface of the outer sheath 10. The plurality of metal spring skeletons 9102 are all fixedly connected to the first connecting sleeve 9101.

[0044] Specifically, when the data cable is round, the cross-section of the part where the outer sheath 10 and the connector 11 meet is circular. By setting a first connecting sleeve 9101 between the outer surfaces of the two, the first connecting sleeve 9101 connecting the outer sheath 10 and the connector 11 is designed as a gradually curved arc rather than a right-angle bend. When bending, the stress can be distributed along the arc, avoiding concentration at a certain point. The metal spring skeleton 9102 is evenly distributed around the axis inside the first connecting sleeve 9101, so as to maintain a certain flexibility and resist repeated bending, thus solving the problem that the part of the data cable connected to the connector 11 is easy to break during use.

[0045] Reference Figure 3 Conductor 1 is made of multiple strands twisted together to form a composite flexible structure;

[0046] Specifically, conductor 1 is formed by multi-strand stranding to create a flexible structure similar to a steel wire rope. Compared to single-strand hard copper, multi-strand stranding can disperse the stress during bending.

[0047] Reference Figure 3 The tensile skeleton 2 is located between multiple conductors 1 to improve the overall tensile strength;

[0048] Specifically, the tensile skeleton 2 is made of 0.1mm aramid fiber, which serves as the central skeleton of the entire data cable. By setting it at the center of multiple conductors 1, the stress can be better distributed.

[0049] Reference Figure 3 The elastic nylon thread 7 is spirally wound around the outer surface of the aluminum foil Mylar tape 6, and the elastic nylon thread 7 is tightly bonded to the aluminum foil Mylar tape 6 and the flame-retardant buffer layer 8.

[0050] Specifically, the elastic nylon thread 7 is spirally wound around the outer surface of the aluminum foil Mylar tape 6, similar to a spring structure. Together with the tensile skeleton 2 inside the thread, it enhances the bending resistance and tensile strength of the thread from the inside out.

[0051] Reference Figure 3 The first connecting sleeve 9101 has a gradient arc shape on its outer surface, and the outer surface of the first connecting sleeve 9101 is provided with a diamond-shaped raised texture.

[0052] Specifically, by designing the first connecting sleeve 9101 as a gradually curved shape, the force is distributed when the wire bends between the wire and the connector 11. At the same time, the diamond-shaped raised texture is used to increase the friction during insertion and removal, so as to avoid excessive pulling and damage to the wire.

[0053] Example 2:

[0054] Please see the appendix Figure 4 - Appendix Figure 5 Based on Embodiment 1, this embodiment also aims to solve the problem that the connection points of the data cable are easily damaged during use when the data cable is a square cable. To solve this problem, this embodiment provides another solution: the connection component 9 includes a second connection sleeve 9201, which is fixedly connected to the connector 11 and the outer sheath 10. A steel frame 9202 is provided between the second connection sleeve 9201 and the outer sheath 10. The outer surface of the outer sheath 10 is quadrilateral, and the top of the outer sheath 10 is provided with a diagonal anti-slip groove. The steel frame 9202 is a rounded three-dimensional square frame.

[0055] Specifically, when the data cable is square, the cross-section of the connection between the outer sheath 10 and the connector 11 is square. The second connecting sleeve 9201 is set on the outer surface of the connection between the outer sheath 10 and the connector 11. By setting it as a double-layer stepped structure, the local thickness is increased to improve the bending resistance. The steel plate skeleton 9202 is set in it to improve the tensile strength of the transition area between the connector 11 and the cable body, which is suitable for frequent plugging and unplugging scenarios. The outer surface of the outer sheath 10 is provided with diagonal anti-slip grooves, which not only improve heat dissipation and distinguish the front and back, but also allow the attached oil stains to be quickly discharged along the guide grooves, keeping the surface of the cable clean and solving the problem that the connection point of the square data cable is easily damaged during use.

[0056] Reference Figure 4 The second connecting sleeve 9201 has a double-layer stepped structure on the outside, which improves its bending resistance.

[0057] Specifically, by making the outer shape of the second connecting sleeve 9201 a double-layer stepped structure, with an outer edge width of 1mm and an inner edge width of 0.5mm, the local thickness is increased, and the bending angle is dispersed by the stepped shape structure when bending, thereby reducing the direct bending degree between the wire and the connector 11 and preventing the connection between the two from breaking due to bending.

[0058] Working principle: Conductor 1 adopts a multi-strand stranded design, which can distribute stress to each strand when bent, reducing the pressure on a single strand, reducing metal fatigue, and maintaining conductivity stability. The inner insulation layer 3 wraps around conductor 1. Its material properties provide insulation and can deform with conductor 1 when bent, protecting conductor 1 while being resistant to bending. The tensile skeleton 2 is located between multiple conductors 1. When the data cable is stretched, it can bear part of the tensile force, preventing the entire tensile force from being borne by conductor 1. The reinforcing braid layer 4 tightens the internal structure and reduces damage to conductor 1, tensile skeleton 2, etc. from external friction. The filler 5 fills the gaps and prevents internal parts from rubbing against each other and causing damage. The aluminum foil Mylar tape 6 wraps around the reinforcing braid layer 4 to block external electromagnetic interference and ensure that data transmission is not affected. The elastic nylon wire 7 is wrapped around the aluminum foil Mylar tape 6 to enhance the bending resistance of the overall structure. The flame-retardant buffer layer 8 and the outer sheath 10 provide external protection to resist environmental factors from damaging the internal parts.

[0059] The first connecting sleeve 9101 in the connecting assembly 9 connects the connector 11 and the outer sheath 10. Its shape design disperses the stress during bending along the arc, avoiding stress concentration at the connection point between the connector 11 and the outer sheath 10. Multiple metal spring skeletons 9102 are wrapped in a ring around the outer surface of the outer sheath 10 and fixed to the first connecting sleeve 9101. This maintains a certain degree of flexibility and can resist repeated bending, reducing damage to the connection part caused by bending. The diamond-shaped raised texture on the outer surface of the first connecting sleeve 9101 increases the friction during insertion and removal, reducing the possibility of damage to the connection part between the connector 11 and the outer sheath 10 due to excessive pulling, thereby protecting the connection part and extending the service life of the data cable.

[0060] The second connecting sleeve 9201 in the connecting assembly 9 connects the connector 11 and the outer sheath 10. Its double-layer stepped structure increases the local thickness, which disperses the bending angle by the stepped shape when bending, reducing the direct bending degree between the cable and the connector 11 and reducing the risk of the connection breaking due to bending. The steel frame 9202 between the second connecting sleeve 9201 and the outer sheath 10 is a rounded three-dimensional square frame, which can enhance the tensile strength of the transition area between the connector 11 and the cable body and adapt to the stress conditions under frequent plugging and unplugging scenarios. The diagonal anti-slip groove on the outer surface of the outer sheath 10 can improve heat dissipation and make it easy to distinguish the positive and negative sides. At the same time, it allows the attached oil to be discharged along the groove, keeping the surface of the cable clean, thereby protecting the connection point of the square data cable and reducing damage.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
