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 human daily life are moving towards electrification. Cables are widely used in industry and the power field. The existing cable structure includes multiple conductors, an insulating layer wrapped around each conductor, a braided layer, and a sheath. 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 will be affected by external pressure in normal use, resulting in a large number of irregular deformations. 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 the actual data is transmitted, causing 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 stressed 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: a plurality of groups of data transmission lines, including core wires and fillers, the core wires including receiving wires, transmitting wires and supporting members, the supporting members being in the shape of an I and being located between the receiving wires and the transmitting wires, the receiving wires and the transmitting wires being arranged at intervals, the fillers burying the core wires, the cross section of the fillers being rectangular, the distances from all sides of the fillers 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 fillers, and The insulating sleeve comprises an inner sleeve, an outer sleeve and a filling strip, wherein the filling strip has a radial cross section and comprises a plurality of accommodating portions, wherein the data transmission line is located in the accommodating portions, 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 comprises an aluminum foil shielding layer and a hot-melt Mylar coating 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.

[0006] By adopting the above scheme, 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, causing damage to the structure of the receiving line and the transmitting line and affecting signal transmission. In the production process of the data line, the staff needs to weld the copper core inside the data transmission line with 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 performs wire stripping, the thickness of the filler is cut more evenly, and the cutting distance is easy to control, which 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, ensuring 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 ensuring that the relative position between the receiving line and the transmitting line is more accurate after the filler coating.

[0007] In one of the embodiments, the support member includes a bearing portion and an isolating portion perpendicular to the bearing portion, the bearing portion cooperates with the outer peripheral surfaces of the receiving line and the transmitting line respectively, and the isolating portion is located in the middle of the bearing portion.

[0008] By adopting the above scheme, since the receiving line and the transmitting line are prone to rolling when the filler is wrapped, making it difficult to control the distance between the receiving line and the transmitting line, the bearing part of the support member limits the receiving line and the transmitting line to ensure that the position of the core wire is 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.

[0009] In one embodiment, the upper and lower ends of the bearing portion are parallel to the upper surface and the 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.

[0010] By adopting the above scheme, the line connecting the centers of the cross sections 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 part of the distance is reserved at the extended end of the core wire for the wire stripping operation to avoid the support member affecting the wire stripping operation, and the length of the support member is limited to avoid the support member being too long and thus affecting the folding performance of the data line.

[0011] In one embodiment, a heat dissipation wire group is provided between the receiving wire and the transmitting wire, 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.

[0012] By adopting the above solution, a heat sink group is arranged 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 sink group. At the same time, when the data line is about to bend, the heat sink group will provide a certain damping to prevent the data line from being bent too much, resulting in cracking or knotting of the filler and the inner sheath.

[0013] 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.

[0014] By adopting the above scheme, 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 straightened state, and the support parts are in a straight line under the pulling action of 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.

[0015] In one embodiment, a supporting mechanism is further provided between the filler and the inner sheath, and the supporting mechanism includes a strut, a supporting column and a protective layer. The strut is L-shaped in cross section and cooperates with the edges of the inner wall of the inner sheath. The two ends of the supporting column are fixed to the edges of both sides of the strut and are in contact with the edges of the filler. The protective layer covers the surface of the filler.

[0016] By adopting the above scheme, when the transmission line and the receiving line are under high load or work for a long time, the filler will receive the heat transferred by the core wire, which will cause thermal expansion and contraction. The middle part of the filler will bulge and squeeze 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 at 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.

[0017] In one embodiment, the protective layer includes a plurality of 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 connected by connecting rods. The metal frames can be circular rings or diamond-shaped frames.

[0018] 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 to absorb the heat of the filler, thereby achieving a heat dissipation effect.

[0019] In one embodiment, when the metal frame is a circular ring, the longitudinal section of the metal frame is circular, and the two ends of the connecting rod are respectively sleeved on the adjacent metal frames.

[0020] By adopting the above solution, the connecting rod can slide along the metal frame and rotate around the metal frame, and 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.

[0021] In one embodiment, when the metal frame is a diamond-shaped frame, two ends of the connecting rod are respectively penetrated through adjacent side walls of the metal frame, and a limiting convex edge is provided at the extended end of the connecting rod.

[0022] By adopting the above scheme, the gap between the metal frames can be shrunk until the side walls of the metal frame and the adjacent metal frame 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 wall of the metal frame. The bending of the protective layer can be completed through the expansion and contraction of the metal frames.

[0023] In one of the embodiments, 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.

[0024] 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, and the heat dissipation pad in the middle of the metal frame is in contact with the filler to further enhance the heat dissipation effect. When the filler further expands, the filler pushes the heat dissipation pad to move along the guide notch to avoid 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 to prevent the metal frame from scratching the inner sheath.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 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 the signal transmission. In the production process of the data line, the staff needs to weld the copper core inside the data transmission line with 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, and the cutting distance is easy to control, which 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.

[0026] 2. Since the receiving wire and the transmitting wire are prone to rolling during the filling wrapping operation, the distance between the receiving wire and the transmitting wire is difficult to control. By setting the support, the heat dissipation wire group and the 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 filling process of the core wire more precise and convenient. Before the filler wraps 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 in a straight line under the pulling action of the heat dissipation wire group, so as to achieve more precise limiting of the receiving wire and the transmitting wire, so that the filling effect is 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.

[0027] 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 transmitted by the core wire, causing thermal expansion and contraction. The middle part of the filler will bulge and squeeze 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 columns 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 to further prevent the inner sheath from breaking. 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

DETAILED DESCRIPTION

[0029] 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.

[0030] A high-strength data cable comprises a plurality of groups of data transmission lines 1 and an insulating sleeve 2.

[0031] Example 1 See also Figure 1-Figure 2 , Figure 1It 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 wires 4 are located at the bottom of the multiple groups of data transmission lines 1, the data transmission line 1 includes a core wire 11 composed of a receiving line 111 and a transmitting line 112, the outer peripheral surfaces of the receiving line 111 and the transmitting line 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 line 111 from the transmitting line 112, and the filler 12 is buried in the core wire 11 to limit the receiving line 111 and the transmitting line 112 to avoid squeezing between the receiving line 111 and the transmitting line 112, thereby affecting the transmission of the signal.

[0032] In this embodiment, the corners of the cross section of the filler 12 are rounded, and the two sides of the cross section of the filler 12 form semicircular structures that are coaxial with the structural line and the transmission line 112. In the production process of the data line, the staff needs to weld the copper core inside the data transmission line 1 with the input interface 5 and the output interface 6, so it is necessary to strip the wire to expose the inside of the data transmission line 1. When the staff needs to strip the wire, the copper core inside the receiving line 111 and the transmitting line 112 is peeled off, and the copper core inside the data transmission line 1 is welded with 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 is convenient for the staff to control the cutting distance and avoid cutting the copper core inside the core line 11 by mistake. In this application, the filler 12 is made of polypropylene material, and the dielectric constant of the polypropylene material is low. While limiting the receiving line 111 and the transmitting line 112, the signal transmission is more stable.

[0033] The insulation includes an inner sheath 21 and an outer sheath 22. The inner sheath 21 covers the filler 12 and the core wire 11. The inner sheath 21 includes an aluminum foil shielding layer 211 and a hot-melt Mylar coating layer 212. The aluminum foil shielding layer 211 covers the surface of the filler 12, which has a signal shielding effect on the core wire 11. The hot-melt Mylar coating layer 212 covers the aluminum foil shielding layer 211. The hot-melt Mylar and the aluminum foil shielding layer 211 are tightly combined to form a strong shielding structure, which effectively blocks external physical damage and chemical corrosion. The outer sheath 22 covers multiple data transmission lines 1. The outer sheath 22 has a similar structure to the inner sheath 21, which has a signal shielding and protection effect on the multiple data transmission lines 1.

[0034] Example 2 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, and the filling strip 23 includes a plurality of accommodating portions, 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.

[0035] Please also read Figure 4-Figure 5 , Figure 4 1 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-sectional shape 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 therein. 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 line. At the same time, it can also prevent the electromagnetic interference generated inside the data line from spreading outward, reducing the risk of signal interference or loss.

[0036] The working principle of this embodiment is as follows: filler 12 is filled between the core wire 11 and the inner sheath 21, and filler 12 limits the receiving wire 111 and the transmitting wire 112, so that the receiving wire 111 and the transmitting wire 112 are always in a separated state. When the core wire 11 is subjected to external force, filler 12 acts as a buffer between the receiving wire 111 and the transmitting wire 112 to avoid mutual squeezing between the receiving wire 111 and the transmitting wire, so that the structures of the receiving wire 111 and the transmitting wire 112 are damaged and the signal transmission is affected. By setting the cross section of filler 12 to a rectangle, the distances from all sides of filler 12 to the core wire 11 are equal. When the staff is stripping the wire, the side of filler 12 is used as a reference, and the blade surface of the cutter is completely attached to the side of filler 12, and then the cutting is performed in a direction perpendicular to the side of filler 12. The thickness of each part of the blade surface cutting filler 12 is relatively uniform, and the core wire 11 will not be cut by mistake due to uneven thickness of filler 12. At the same time, the cut part of filler 12 is relatively complete, which is convenient for stripping from core wire 11.

[0037] Example 3 See also Figure 6-Figure 7 , Figure 7 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 be matched 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 located in the middle of the bearing portion 1131. The upper and lower ends of the bearing portion 1131 are parallel to the upper surface and the lower surface of the filler 12, respectively. The support members 113 are arranged at intervals 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 formed from polytetrafluoroethylene material. The 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.

[0038] A heat sink group 114 is provided between the receiving line 111 and the transmitting line 112. Two heat sinks are provided at the upper and lower parts of the heat sink group 114. The heat sinks can be made of copper or aluminum alloy. The heat sink group 114 includes multiple sections. The two ends of each section of the heat sink group 114 are respectively connected to two adjacent isolation parts 1132. The two heat sinks of the heat sink group 114 are respectively connected to the upper and lower ends of the isolation part 1132. When the receiving line 111 and the transmitting line 112 are working, the heat emitted can be absorbed by the heat sink group 114. At the same time, when the data line is about to bend, the heat sink group 114 will provide a certain damping to prevent the data line from being bent too much, resulting in cracking or knotting of the filler 12 and the inner sheath 21.

[0039] Both ends of the core wire 11 are provided with protective sleeves 115, and the 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 realize a detachable connection between the protective sleeves 115 and the core wire 11. The protective sleeves 115 are in the shape of a prism, 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 on the core wire 11. In 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 easy to rub against the plug-in interface of the mold, resulting in the copper core inside the receiving wire 111 and the transmitting wire 112 bifurcating, and the bifurcated copper core rubbing against the inner wall of the mold, making it difficult for the receiving wire 111 and the transmitting wire 112 to be inserted into the mold. The top of the protective sleeve 115 can match with the entrance of the mold, making it easier for the core wire 11 to be inserted into the mold.

[0040] 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 a preset position during the filling process, it is ensured that The filler 12 can evenly bury the core wire 11, but the receiving wire 111 and the transmitting wire 112 are prone to rolling, resulting in the distance between the receiving wire 111 and the transmitting wire 112 being difficult to control. The bearing portion 1131 of the support 113 limits the receiving wire 111 and the transmitting wire 112, thereby making the distance between the receiving wire 111 and the transmitting wire 112 more precise, and at the same time preventing the receiving wire 111 and the transmitting wire 112 from rubbing against the side wall of the mold, causing 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 the receiving wire 111 and the transmitting wire 112 from being squeezed against each other. When the wire stripping operation is required, the protective sleeves 115 at both ends of the core wire 11 can be removed.

[0041] Example 4 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 the above embodiment, except that a support mechanism 3 is also included between the filler 12 layer and the inner sheath 21, and 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 on both 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 embedded with the filler 12 are placed to a preset position through a mold, and then limited by aluminum foil Mylar coating, and finally covered with insulating rubber to form the inner sheath 21 on the outside of the filler 12. The protective layer 33 includes a plurality of 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 are gaps 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.

[0042] In this embodiment, the metal frame 331 is circular, and 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 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.

[0043] 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, and will produce thermal expansion and contraction. The middle part of the filler 12 will bulge and squeeze 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 there is a gap 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 to further prevent the inner sheath 21 from breaking.

[0044] During the process of the filler 12 expanding due to heat, the filler 12 squeezes the metal rod and the connecting rod 332. Since the contact area between the metal frame 331 and the connecting rod 332 and the filler 12 is small, the metal frame 331 and the connecting rod 332 can be buried in the surface of the filler 12 to absorb the heat of the filler 12, thereby achieving a heat dissipation effect. Since the metal frame 331 and the connecting rod 332 are made of aluminum alloy, the metal frame 331 can not only absorb heat, but also increase the shielding effect of the data line signal. Since the deformation performance of the protective layer 33 is better when the metal frame 331 is circular, this embodiment is suitable for the core wire 11 with a small cross-sectional area.

[0045] Example 5 See also Figure 10-11 , Fig.10 3 is a schematic diagram of the internal structure of the data transmission line of the fifth embodiment of the present application. The structure of this embodiment is basically the same as that of the above embodiments, except that the metal frame 331 is rhombus-shaped, the two ends of the connecting rod 332 are respectively penetrated by the side walls of the adjacent metal frames 331, the extended end of the connecting rod 332 is provided with a limiting convex edge 3321, the metal frame 331 is provided with a heat dissipation pad 333, the top of the metal frame 331 is blocked by a metal sheet 3312, and the side wall of the metal frame 331 is provided with a guide notch 3311 that cooperates with the heat dissipation pad 333. The gap between the metal frames 331 can be contracted along the direction of the connecting rod 332 until the metal frame 331 and the side wall of the adjacent metal frame 331 abut against each other, and the metal frames 331 can also be expanded with each other. When the metal frames 331 are in the expanded state, the limiting convex edges 3321 at both ends of the connecting rod 332 abut against the inner wall of the metal frame 331, and the bending of the protective layer 33 can be completed by the expansion and contraction of the metal frames 331.

[0046] The working principle of this embodiment is as follows: when the filler 12 expands due to heat, the edge of the metal frame 331 is embedded in the filler 12 to dissipate heat from the filler 12, and the heat dissipation pad 333 in the middle of the metal frame 331 is in contact with the filler 12, further enhancing the heat dissipation effect. When the filler 12 further expands, the filler 12 pushes the heat dissipation pad 333 to move along the guide notch 3311, avoiding the heat dissipation pad 333 exerting pressure on the filler 12 during the expansion process, causing the core wire 11 to be squeezed. The metal sheet 3312 on 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, avoiding the metal frame 331 from scratching the inner sheath 21. When the metal frame 331 is rhombus-shaped, the deformation performance of the protective layer 33 is poor, but the heat dissipation effect is better, so this embodiment is suitable for core wires 11 with larger cross-sections.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
