Description

Technical Field

[0001] The present application relates to the technical field of data transmission lines, and in particular to a high-strength data cable. Background Art

[0002] As we all know, with the development of science and technology, both industry and daily life are moving towards electrification. Cables are widely used in industry and the power sector. The existing cable structure consists of multiple conductors, an insulation layer covering each conductor, a braided layer, a sheath, and other parts. Data cables include data cables or data optical cables. Data cables are mainly used for network wiring in residential areas and commercial buildings. Data optical cables are mainly used for signal data transmission. Therefore, the matrix strength performance of data cables must be better than other ordinary cables. Because data cables are subject to external pressure in normal use, they will produce a large amount of irregular deformation. Under normal circumstances, this deformation will cause deformation and extrusion of the actual cable core inside, resulting in serious deformation of the internal signal transmission cable core, which will cause certain obstructions when actually transmitting data, resulting in unstable signal transmission and affecting normal use.

[0003] Therefore, how to effectively solve the mutual squeezing problem between the receiving line and the transmitting line and maintain the stability and reliability of the data line when it is bent and subjected to stress has become a technical problem that needs to be solved urgently. Summary of the Invention

[0004] The purpose of this application is to overcome the above technical problems and provide a high-strength data cable.

[0005] A high-strength data cable, comprising: multiple groups of data transmission lines, including core wires and fillers, the core wires including receiving wires, transmitting wires and a support member, the support member being in the shape of an "I" and located between the receiving wires and the transmitting wires, the receiving wires and the transmitting wires being spaced apart, the filler burying the core wires, the filler having a rectangular cross-section, the distances from all sides of the filler to the core wires being equal, the line connecting the cross-section centers of the receiving wires and the transmitting wires being parallel to the upper and lower surfaces of the filler, and

[0006] The insulating sleeve includes an inner sleeve, an outer sleeve and a filling strip. The filling strip has a radial cross-section and includes multiple accommodating portions. The data transmission line is located in the accommodating portion. The inner sleeve covers the filler and the core wire. The inner wall of the inner sleeve is provided with a signal shielding material. The inner sleeve includes an aluminum foil shielding layer and a hot-melt Mylar covering layer. The outer sleeve covers the data transmission line and the filling strip, and the filling strip abuts against the inner wall of the outer sleeve.

[0007] By adopting the above solution, since the receiving line and the transmitting line are prone to extrusion, the filler limits the receiving line and the transmitting line, so that the receiving line and the transmitting line are always in a separated state, avoiding mutual extrusion between the receiving line and the transmitting line, which damages the structure of the receiving line and the transmitting line and affects signal transmission. During the production process of the data line, the staff needs to weld the copper core inside the data transmission line to the input interface and the output interface, so it is necessary to strip the wire to expose the inside of the data transmission line. By setting the filler cross-section to a rectangle, the distance from all sides of the filler to the core wire is equal. When the staff strips the wire, the thickness of the filler is cut more evenly, the cutting distance is easy to control, and it is convenient for the staff to strip the wire. Before the data transmission line is processed, the support can support the receiving line and the transmitting line to ensure that the relative position of the receiving line and the transmitting line will not change during the filler coating process, and at the same time ensure that the relative position between the receiving line and the transmitting line is more accurate after the filler coating.

[0008] In one embodiment, the support member includes a bearing portion and an isolating portion perpendicular to the bearing portion, the bearing portion cooperates with the outer circumferences of the receiving line and the transmitting line respectively, and the isolating portion is located in the middle of the bearing portion.

[0009] By adopting the above solution, since rolling is likely to occur between the receiving line and the transmitting line during the wrapping operation of the filler, resulting in difficulty in controlling the distance between the receiving line and the transmitting line, the bearing portion of the support member limits the receiving line and the transmitting line to ensure that the position of the core wire is centrally symmetrical with the center of the filler. At the same time, the support member can further avoid mutual extrusion between the receiving line and the transmitting line.

[0010] In one embodiment, the upper and lower ends of the bearing portion are parallel to the upper surface and lower surface of the filler respectively, the support members are arranged at intervals and are more than 10 mm away from the extended end of the core wire, and the length of the support members is 2-5 mm.

[0011] By adopting the above solution, the line connecting the cross-section centers of the limited receiving line and the transmitting line can be parallel to the upper surface and the lower surface of the filler, and a certain distance is reserved at the extended end of the core wire for the wire stripping operation to prevent the support member from affecting the wire stripping operation. The length of the support member is limited to prevent the support member from being too long and thus affecting the folding performance of the data cable.

[0012] In one embodiment, a heat dissipation wire group is provided between the receiving line and the transmitting line. The heat dissipation wire group includes two heat dissipation wires arranged one above the other. The heat dissipation wire group includes multiple sections, and both ends of each section of the heat dissipation wire group are respectively connected to the adjacent isolation parts.

[0013] By adopting the above solution, a heat dissipation wire group is set between the receiving line and the transmitting line. The heat emitted by the receiving line and the transmitting line when they are working can be absorbed by the heat dissipation wire group. At the same time, when the data line is about to bend, the heat dissipation wire group will provide a certain amount of damping to prevent the data line from bending too much and causing cracking or knotting of the filler and the inner sheath.

[0014] In one embodiment, protective covers are provided at both ends of the core wire, and the protective covers are detachably connected to the core wire and the heat dissipation wire group respectively. The protective covers are prism-shaped, and the bottom surface of the protective covers is flush with the cross-section of the filler.

[0015] By adopting the above solution, before the core wire is filled with filler, the protective cover can effectively protect the end of the core wire. At the same time, the design of the protective cover can make the filling process of the core wire more accurate and convenient. Before the filler covers the core wire, the protective covers at both ends of the core wire can be pulled in opposite directions. At this time, the receiving wire and the transmitting wire are both in a straight line, and the support parts are in a straight line under the pulling action of the heat dissipation wire group, thereby achieving more precise limiting of the receiving wire and the transmitting wire, and making the filling effect better. The wedge-shaped design of the protective cover makes it easier to insert the two ends of the core wire into the mold.

[0016] In one embodiment, a support mechanism is further provided between the filler and the inner sheath, and the support mechanism includes a strut, a support column and a protective layer. The strut is L-shaped in cross section and cooperates with the corners of the inner wall of the inner sheath. The two ends of the support column are fixed to the edges of both sides of the strut and are in contact with the corners of the filler. The protective layer covers the surface of the filler.

[0017] By adopting the above solution, when the transmission line and the receiving line are under high load or working for a long time, the filler will receive the heat transferred by the core wire, resulting in thermal expansion and contraction. The middle part of the filler will bulge, thereby squeezing the inner sheath. At this time, the inner sheath is prone to cracking during the bending process. By providing a support mechanism between the filler and the inner sheath, the filler is supported by the support column of the support mechanism, so that a gap exists between the filler and the inner sheath. When the filler expands due to heat, the expanded part is located in the gap and will not squeeze the inner sheath. The protective layer covers the surface of the filler, further preventing the inner sheath from cracking.

[0018] In one embodiment, the protective layer includes multiple metal frames and connecting rods. The metal frames are circular and distributed in an array on the surface of the filler. There is a gap between adjacent metal frames and they are all connected by connecting rods. The metal frames can be circular rings or diamond frames.

[0019] By adopting the above solution, when the filler expands due to heat, the filler squeezes the metal frame and the connecting rod. Since the contact area between the metal frame and the connecting rod and the filler is small, the metal frame and the connecting rod can be buried in the surface of the filler, absorbing the heat of the filler, thereby achieving a heat dissipation effect.

[0020] In one embodiment, when the metal frame is a circular ring, the longitudinal section of the metal frame is circular, and both ends of the connecting rod are respectively sleeved on the adjacent metal frames.

[0021] By adopting the above solution, the connecting rod can slide along the metal frame and rotate around the metal frame at the same time. The position between the metal frames can be changed, so that the protective cover can be deformed as the filler is bent, thereby ensuring that the bendability of the data cable is not affected.

[0022] In one embodiment, when the metal frame is a diamond-shaped frame, both ends of the connecting rod are respectively passed through adjacent side walls of the metal frame, and the extended end of the connecting rod is provided with a limiting protrusion.

[0023] By adopting the above solution, the gaps between the metal frames can be shrunk until the side walls of the metal frames and adjacent metal frames abut against each other, and the metal frames can also be expanded relative to each other. When the metal frames are in the expanded state, the limiting protrusions at both ends of the connecting rod abut against the inner walls of the metal frames. The bending of the protective layer can be completed by the expansion and contraction of the metal frames.

[0024] In one embodiment, when the metal frame is diamond-shaped, a heat dissipation pad is provided in the metal frame, the top of the metal frame is sealed by a metal sheet, and the side wall of the metal frame is provided with a guide notch that cooperates with the heat dissipation pad.

[0025] By adopting the above solution, when the filler expands due to heat, the filler is embedded in the edge of the metal frame to dissipate heat from the filler. The heat dissipation pad in the middle of the metal frame is in contact with the filler, further enhancing the heat dissipation effect. When the filler further expands, the filler pushes the heat dissipation pad to move along the guide notch, avoiding the heat dissipation pad exerting pressure on the filler during the expansion process, causing the core wire to be squeezed. The metal sheet on the top of the metal frame improves the heat dissipation efficiency of the metal frame while increasing the surface area of ​​the protective layer, preventing the metal frame from scratching the inner sheath.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Since the receiving line and the transmitting line are prone to extrusion, the filler limits the receiving line and the transmitting line, so that the receiving line and the transmitting line are always in a separated state, avoiding mutual extrusion between the receiving line and the transmitting line, which damages the structure of the receiving line and the transmitting line and affects signal transmission. In the production process of the data cable, the staff needs to weld the copper core inside the data transmission line to the input and output interfaces, so it is necessary to strip the wire to expose the inside of the data transmission line. By setting the filler cross-section to a rectangle, the distance from all sides of the filler to the core wire is equal. When the staff strips the wire, the thickness of the filler is cut more evenly, the cutting distance is easy to control, and it is convenient for the staff to strip the wire. Before the data transmission line is processed, the support can support the receiving line and the transmitting line to ensure that the relative position of the receiving line and the transmitting line does not change during the filler coating process, and at the same time ensure that the relative position between the receiving line and the transmitting line is more accurate after the filler coating.

[0028] 2. Since the receiving wire and the transmitting wire are prone to rolling during the filler coating operation, the distance between the receiving wire and the transmitting wire is difficult to control. By providing a support, a heat dissipation wire group and a protective cover, the protective cover can effectively protect the end of the core wire before the core wire is filled with filler. At the same time, the design of the protective cover can make the core wire filling process more accurate and convenient. Before the filler coats the core wire, the protective covers at both ends of the core wire can be pulled in opposite directions. At this time, the receiving wire and the transmitting wire are both in a straightened state, and the support is pulled in a straight line by the heat dissipation wire group, thereby achieving more precise positioning of the receiving wire and the transmitting wire, making the filling effect better, and the wedge-shaped design of the protective cover makes it easier to insert the two ends of the core wire into the mold.

[0029] 3. Since heat is generated in the process of transmitting signals between the transmission line and the receiving line, under high load or long-term working conditions, the filler will receive the heat transferred by the core wire, resulting in thermal expansion and contraction. The middle part of the filler will bulge, thereby squeezing the inner sheath. At this time, the inner sheath is prone to cracking during the bending process. By providing a supporting mechanism between the filler and the inner sheath, the filler is supported by the supporting column of the supporting mechanism, so that a gap exists between the filler and the inner sheath. When the filler expands due to heat, the expanded part is located in the gap and will not squeeze the inner sheath. The protective layer covers the surface of the filler, further preventing the inner sheath from cracking. At the same time, during the process of thermal expansion of the filler, the protective layer can be embedded in the filler to dissipate heat from the filler. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Therefore, it is necessary to provide a high-strength data line that prevents the receiving line 111 and the transmitting line 112 of the data line from being squeezed against each other.

[0043] A high-strength data cable comprises a plurality of data transmission lines 1 and an insulating sleeve 2.

[0044] Example 1

[0045] See also Figure 1-Figure 2 , Figure 1This is a cross-sectional view of a high-strength data cable provided in the first embodiment of the application, including multiple groups of data transmission lines 1, ground wires 4 and transmission lines 5. The transmission lines 5 include live wires and neutral wires for transmitting current. The ground wire 4 is located at the bottom of the multiple groups of data transmission lines 1. The data transmission line 1 includes a core wire 11 consisting of a receiving wire 111 and a transmitting wire 112. The outer peripheral surfaces of the receiving wire 111 and the transmitting wire 112 are wrapped with an inner core wire 11 insulation layer made of insulating material for insulation. The inner core wire 11 insulation layer separates the receiving wire 111 from the transmitting wire 112. The filler 12 is buried in the core wire 11 to limit the receiving wire 111 and the transmitting wire 112 to avoid squeezing between the receiving wire 111 and the transmitting wire 112, thereby affecting the transmission of the signal.

[0046] In this embodiment, the corners of the cross section of the filler 12 are rounded, and semicircular structures are formed on both sides of the cross section of the filler 12, which are coaxial with the structural line and the transmission line 112. During the production process of the data line, the staff needs to weld the copper core inside the data transmission line 1 to the input interface 5 and the output interface 6, so it is necessary to perform wire stripping to expose the inside of the data transmission line 1. When the staff needs to perform wire stripping, the copper core inside the receiving line 111 and the transmitting line 112 is peeled out, and the copper core inside the data transmission line 1 is welded to the input interface and the output interface. During the cutting process, the staff cuts the data transmission line 1 from all directions, and the distance from the surface of the filler 12 to the core line 11 is equal, which makes it easier for the staff to control the cutting distance and avoid accidentally cutting the copper core inside the core line 11. In this application, the filler 12 is made of polypropylene material. The dielectric constant of the polypropylene material is low. While limiting the receiving line 111 and the transmitting line 112, it makes the signal transmission more stable.

[0047] The insulation comprises an inner sheath 21 and an outer sheath 22. The inner sheath 21 encases the filler 12 and the core wire 11. The inner sheath 21 comprises an aluminum foil shielding layer 211 and a hot-melt Mylar coating 212. The aluminum foil shielding layer 211 covers the surface of the filler 12, shielding the core wire 11. The hot-melt Mylar coating 212 covers the aluminum foil shielding layer 211. The hot-melt Mylar and aluminum foil shielding layers 211 are tightly bonded to form a strong shielding structure, effectively preventing external physical damage and chemical corrosion. The outer sheath 22 encases multiple data transmission lines 1. Similar in structure to the inner sheath 21, the outer sheath 22 provides signal shielding and protection for the multiple data transmission lines 1.

[0048] Example 2

[0049] See also Figure 3 , Figure 3A schematic diagram of a high-strength data cable structure is provided for the second embodiment of the present application. The structure of this embodiment is basically the same as the above embodiment, except that the cross-section of the filler 12 is rectangular, and the insulating sleeve 2 also includes a filling strip 23, wherein the filling strip 23 is made of soft rubber material and has a radial cross-section. The filling strip 23 includes a plurality of accommodating portions, and the data transmission line 1 is located in the accommodating portion. The inner sheath 21 covers the filler and the core wire 11, and the outer sheath 22 covers the data transmission line 1, and the filling strip 23 abuts against the inner wall of the outer sheath 22.

[0050] Please also refer to Figure 4-Figure 5 , Figure 4 This is a schematic diagram of the data transmission line structure. The receiving line 111 and the transmitting line 112 are spaced apart, and the filler 12 buries the core line 11. The filler 12 is formed by solidifying molten polypropylene material in a mold. Since the cross-section of the filler 12 is rectangular, the distances from all sides of the filler 12 to the core line 11 are equal. The line connecting the cross-sectional centers of the receiving line 111 and the transmitting line 112 is parallel to the upper surface of the filler 12. During the production process, the receiving line 111 and the transmitting line 112 are placed in a mold. The shape of the mold is the same as the cross-section of the filler 12. The filler 12 in a molten state is poured into the mold. The filler 12 solidifies and buries the receiving line 111 and the transmitting line 112 inside, and the positions of the receiving line 111 and the transmitting line 112 are fixed. The inner sheath 21 covers the filler 12 and the core wire 11. The inner wall of the inner sheath 21 is provided with a signal shielding material. The signal shielding material is aluminum foil Mylar. In actual production, the aluminum foil Mylar can be wrapped on the surface of the filler 12 to shield the core wire 11 to prevent external electromagnetic interference from affecting the signal transmitted inside the data cable. At the same time, it can also prevent the electromagnetic interference generated inside the data cable from spreading outward, reducing the risk of signal interference or loss.

[0051] The working principle of this embodiment is as follows: filler 12 is filled between the core wire 11 and the inner sheath 21. The filler 12 limits the position of the receiving wire 111 and the transmitting wire 112, keeping them separated. When the core wire 11 is subjected to external force, the filler 12 acts as a buffer between the receiving wire 111 and the transmitting wire 112, preventing the receiving wire 111 and the transmitting wire 112 from being squeezed against each other, which could damage the structures of the receiving wire 111 and the transmitting wire 112 and affect signal transmission. By setting the cross-section of the filler 12 to a rectangular shape, the distance from all sides of the filler 12 to the core wire 11 is equal. During the wire stripping process, the blade of the cutting tool is completely in contact with the side of the filler 12, using the side of the filler 12 as a reference. Then, the cutting is carried out in a direction perpendicular to the side of the filler 12. The thickness of the filler 12 cut by each part of the blade is relatively uniform, preventing the core wire 11 from being accidentally cut due to uneven thickness of the filler 12. At the same time, the cut portion of the filler 12 is relatively complete, making it easier to peel off from the core wire 11.

[0052] Example 3

[0053] See also Figure 6-Figure 7 , Figure 7 This is a schematic diagram of the internal structure of the data transmission line of the third embodiment of the present application. The structure of this embodiment is basically the same as that of the above embodiment, except that the core line 11 also includes a support member 113, and the support member 113 is located between the receiving line 111 and the transmitting line 112. The support member 113 includes a bearing portion 1131 that can respectively cooperate with the outer peripheral surface of the receiving line 111 and the transmitting line 112, and an isolation portion 1132 that is perpendicular to the bearing portion 1131 and is located in the middle of the bearing portion 1131. The upper and lower ends of the bearing portion 1131 are respectively parallel to the upper surface and the lower surface of the filler 12. The support members 113 are spaced apart and are spaced apart from the core line 11. The extended ends of 11 are more than 10 mm apart and are used for the stripping operation of the core wire 11 to prevent the support member 113 from affecting the stripping operation. The length of the support member 113 is 2-5 mm to prevent the support member 113 from being too long and affecting the folding performance of the data line. The support member 113 can be processed and molded from polytetrafluoroethylene material. Polytetrafluoroethylene material has good mechanical properties, such as flexibility and stretchability, and has little effect on signal transmission. It can provide good support for the receiving line 111 and the transmitting line 112, and can also ensure the integrity of the signal transmission between the receiving line 111 and the transmitting line 112.

[0054] A heat sink assembly 114 is provided between the receiving line 111 and the transmitting line 112. Two heat sinks are arranged above and below the heat sink assembly 114. The heat sinks can be made of copper or aluminum alloy. The heat sink assembly 114 comprises multiple sections, with each section's ends connected to two adjacent isolation sections 1132. The two heat sinks in the heat sink assembly 114 are connected to the upper and lower ends of the isolation sections 1132, respectively. Heat generated by the receiving line 111 and the transmitting line 112 during operation is absorbed by the heat sink assembly 114. Furthermore, when the data line is about to bend, the heat sink assembly 114 provides a certain degree of damping, preventing excessive bending that could cause cracking or kinking of the filler 12 and the inner sheath 21.

[0055] Protective sleeves 115 are provided at both ends of the core wire 11. Protective sleeves 115 are provided with plug-in holes. The core wire 11 and the heat dissipation wire are respectively inserted into the plug-in holes to achieve a detachable connection between the protective sleeves 115 and the core wire 11. The protective sleeves 115 are prism-shaped, and the bottom surface of the protective sleeves 115 is flush with the cross-section of the filler 12. Since the copper cores at both ends of the receiving wire 111 and the transmitting wire 112 are partially exposed and easily worn, the protective sleeves 115 play a protective role for the core wire 11. During the process of inserting the receiving wire 111 and the transmitting wire 112 into the mold, one end of the receiving wire 111 and the transmitting wire 112 is likely to rub against the plug-in interface of the mold, causing the copper core inside the receiving wire 111 and the transmitting wire 112 to fork. The forked copper core rubs against the inner wall of the mold, making it difficult to insert the receiving wire 111 and the transmitting wire 112 into the mold. The top of the protective sleeve 115 can match the entrance of the mold, making it easier to insert the core wire 11 into the mold.

[0056] The working principle of this embodiment is as follows: before the filler 12 covers the core wire 11, the protective sleeves 115 at both ends of the core wire 11 can be pulled in opposite directions. At this time, the receiving wire 111, the transmitting wire 112 and the heat dissipation wire group 114 are in a straightened state. The support member 113 is perpendicular to the core wire 11 under the pulling action of the heat dissipation wire group 114, and each part of each support member 113 is in a straight line. Since it is necessary to ensure that the receiving wire 111 and the transmitting wire 112 are covered at the preset position during the filling process, the receiving wire 111 and the transmitting wire 112 are covered at the preset position, thereby ensuring that the receiving wire 111 and the transmitting wire 112 are covered at the preset position. The filler 12 can evenly bury the core wire 11, but rolling easily occurs between the receiving wire 111 and the transmitting wire 112, making it difficult to control the distance between them. The bearing portion 1131 of the support 113 limits the position of the receiving wire 111 and the transmitting wire 112, thereby making the distance between them more precise and preventing the receiving wire 111 and the transmitting wire 112 from rubbing against the side wall of the mold, which could cause the insulation layer of the receiving wire 111 and the transmitting wire 112 to break. After the filler 12 covers the core wire 11, the isolation portion 1132 of the support 113 separates the receiving wire 111 and the transmitting wire 112, further preventing them from squeezing each other. When stripping is required, the protective covers 115 at both ends of the core wire 11 can be removed.

[0057] Example 4

[0058] See also Figure 8-Figure 9 , Figure 8This is a schematic diagram of the internal structure of the data transmission line of the fourth embodiment of the present application. The structure of this embodiment is basically the same as that of the above embodiment, except that a support mechanism 3 is also included between the filler 12 layer and the inner sheath 21. The support mechanism 3 includes a strut 31, a support column 32 and a protective layer 33. The cross-section of the strut 31 is L-shaped and cooperates with the edges of the inner wall of the inner sheath 21. The two ends of the support column 32 are fixed to the edges of the two sides of the strut 31 and contact with the edges of the filler 12. The protective layer 33 covers the surface of the filler 12. The support column 32 and the strut 31 are both made of insulating rubber. In the actual production process, the protective layer 33 is first covered on the surface of the filler 12, and then the core wire 11, the strut 31 and the support column 32 after the filler 12 is embedded are placed to a preset position through a mold, and then they are limited by aluminum foil Mylar. Finally, they are covered with insulating rubber to form the inner sheath 21 on the outside of the filler 12. The protective layer 33 includes multiple metal frames 331 and connecting rods 332. The metal frames 331 are circular and distributed in an array on the surface of the filler 12. There is a gap between adjacent metal frames 331 and they are connected by connecting rods 332. The metal frames 331 and connecting rods 332 are made of aluminum alloy.

[0059] In this embodiment, the metal frame 331 is circular. At this time, the cross-section of the metal frame 331 is circular. The two ends of the connecting rod 332 are respectively mounted on the adjacent metal frames 331. The connecting rod 332 can slide along the metal frame 331 and can rotate around the metal frame 331. The position between the metal frames 331 can be changed, so that the protective cover 115 can be deformed as the filler 12 is bent, thereby ensuring that the bendability of the data line is not affected.

[0060] The working principle of this embodiment is as follows: when the transmission line and the receiving line 111 are under high load or work for a long time, the filler 12 will receive the heat transferred by the core wire 11, which will cause thermal expansion and contraction. The middle part of the filler 12 will bulge, thereby squeezing the inner sheath 21. At this time, the inner sheath 21 is prone to cracking during the bending process. By arranging a support mechanism 3 between the filler 12 and the inner sheath 21, the filler 12 is supported by the support column 32 of the support mechanism 3, so that a gap exists between the filler 12 and the inner sheath 21. When the filler 12 expands due to heat, or the inner sheath 21 is squeezed by external force, the expanded part is located at the gap and will not squeeze the inner sheath 21. The protective layer 33 covers the surface of the filler 12, further preventing the inner sheath 21 from breaking.

[0061] As filler 12 expands due to heat, it squeezes the metal rod and connecting rod 332. Since the metal frame 331 and connecting rod 332 have a small contact area with filler 12, they can be embedded in the surface of filler 12, absorbing heat from the filler 12 and thus providing a heat dissipation effect. Since the metal frame 331 and connecting rod 332 are made of aluminum alloy, the metal frame 331 not only absorbs heat but also enhances the data line signal shielding effect. Since a circular metal frame 331 improves the deformation performance of the protective layer 33, this embodiment is suitable for core wires 11 with a small cross-sectional area.

[0062] Example 5

[0063] See also Figure 10-11 , Figure 10 This is a schematic diagram of the internal structure of a data transmission cable according to a fifth embodiment of the present application. This embodiment has essentially the same structure as the previous embodiments, except that the metal frame 331 is diamond-shaped, and the ends of the connecting rod 332 penetrate the sidewalls of the adjacent metal frame 331. The extended ends of the connecting rod 332 are provided with stopper ridges 3321. A heat sink 333 is provided inside the metal frame 331. The top of the metal frame 331 is sealed with a metal sheet 3312, and the sidewalls of the metal frame 331 are provided with guide notches 3311 that mate with the heat sink 333. The gaps between the metal frames 331 can be contracted along the direction of the connecting rod 332 until the sidewalls of the metal frames 331 abut against each other. The metal frames 331 can also be expanded relative to each other. When the metal frames 331 are in the expanded state, the stopper ridges 3321 at the ends of the connecting rod 332 abut against the inner walls of the metal frames 331. The expansion and contraction of the metal frames 331 complete the bending of the protective layer 33.

[0064] The working principle of this embodiment is as follows: when the filler 12 expands due to heat, the edge of the metal frame 331 embeds the filler 12, dissipating heat from the filler 12. The heat dissipation pad 333 in the middle of the metal frame 331 abuts the filler 12, further enhancing the heat dissipation effect. As the filler 12 further expands, the filler 12 pushes the heat dissipation pad 333 along the guide notch 3311, preventing the heat dissipation pad 333 from exerting pressure on the filler 12 during expansion, which could cause the core wire 11 to be squeezed. The metal sheet 3312 at the top of the metal frame 331 improves the heat dissipation efficiency of the metal frame 331 while increasing the surface area of ​​the protective layer 33, preventing the metal frame 331 from scratching the inner sheath 21. When the metal frame 331 is diamond-shaped, the deformation performance of the protective layer 33 is poor, but the heat dissipation effect is better. Therefore, this embodiment is suitable for core wires 11 with larger cross-sections.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
