[0031] The present application provides a data cable 10 for connecting a power source to an electronic device and providing power to the electronic device or transmitting signals, and is generally used for charging a mobile phone, a tablet or a notebook.

[0032] The data line 10 of the present application includes a line body 11 and a plug assembly 12 connected to the line body 11. The plug assembly 12 is used to connect to an electronic device, and the line body 11 is used to connect the plug assemblies 12 at both ends of the line body 11. The plug assembly 12 includes a metal shell 121 and a circuit board 122 and a connecting terminal arranged in the metal shell 121; the connecting terminal is arranged on the circuit board 122 and connected to the electronic device; the line body 11 is also connected to the circuit board 122, and the signal is transmitted from one end through the line body 11 to the circuit board 122 to the terminal, and then to the electronic device. The relevant technology of the plug assembly 12 structure is conventional technology in the industry, and will not be elaborated here.

[0033] Furthermore, a first insulating layer 13 is provided at the connection between the plug assembly 12 and the wire body 11, and the first insulating layer 13 extends to the upper plug assembly 12 and the wire body 11. It can be understood that the first insulating layer 13 is provided on part of the plug assembly 12 and part of the wire body 11, and part of the plug assembly 12 and part of the wire body 11 are one end of each other connected to each other. The first insulating layer 13 also wraps the connection between the plug assembly 12 and the wire body 11 to improve the connection strength between the plug assembly 12 and the wire body 11, and prevent the user from easily pulling the wire body 11 and tearing it off; the metal sleeve 14 is provided on the first insulating layer 13, and is correspondingly provided at the connection between the plug assembly 12 and the wire body 11, which not only strengthens the connection strength between the plug assembly 12 and the wire body 11, but also due to the high thermal conductivity of the metal, the provision of the metal sleeve 14 can also conduct the heat generated by the plug assembly 12 to the metal sleeve 14, and quickly and evenly disperse the heat, quickly conduct the heat out, and protect the electronic components in the plug assembly 12.

[0034] In one embodiment, if Figure 1 to Figure 2 As shown, a first insulating layer 13 is provided to cover the circuit board 122 and the wire body 11 connected to the circuit board 122, which not only strengthens the connection strength between the plug assembly 12 and the wire body 11, but also performs insulation treatment; a metal sleeve 14 is provided to be sleeved on the first insulating layer 13 to enhance the strength and shear force of the data line 10, and the metal sleeve 14 is completely sleeved on the first insulating layer 13, so that the heat transferred to the first insulating layer 13 can be quickly dispersed on the metal sleeve 14 to quickly dissipate heat and protect the electronic components in the plug assembly 12. Since the thermal conductivity of the metal sleeve 14 is higher than that of the insulating material, the metal sleeve 14 can quickly transfer heat. Finally, a second insulating layer 15 is sleeved on the outer layer of the metal sleeve 14 to prevent the metal sleeve 14 from being scratched, which seriously affects the appearance of the data line 10, and can further isolate the heat to prevent the user from directly contacting the high-temperature metal sleeve 14, resulting in a bad experience of being hot.

[0035] In one embodiment, if Figure 1 to Figure 2As shown, the metal sleeve 14 is completely covered on the first insulating layer 13 to increase the metal heat conduction area, so that the heat is dissipated more quickly and the thermal conductivity is improved. The first insulating layer 13 is set on part of the plug assembly 12 and part of the line body 11, and the metal sleeve 14 corresponds to part of the plug assembly 12 and part of the line body 11, increasing the shear force and pressure resistance of the plug assembly 12.

[0036] In one embodiment, if Figure 1 to Figure 2 As shown, the plug assembly 12 includes a metal shell 121 and a circuit board 122 disposed in the metal shell 121. The plug assembly 12 is provided with a terminal electrically connected to the electronic device, and the terminal is disposed on the circuit board 122. The circuit board 122 also includes various electronic components for controlling current transmission and signal transmission. The wire body 11 is then connected to the circuit board 122, and the terminal is electrically connected to the wire body 11 through the circuit board 122. The terminal is connected to the circuit board 122, and the terminal is positioned on the circuit board 122 by injection molding a plastic layer. The metal shell 121 is sleeved on the outside of the plastic layer to protect the terminal and the circuit board 122. Usually, the metal shell 121 not only wraps the terminal, but also wraps part of the circuit board 122, and the other part of the circuit board 122 is exposed outside the metal shell 121 to facilitate the connection between the circuit board 122 and the wire body 11. Of course, the circuit board 122 can also be completely disposed in the metal shell 121. The first insulating layer 13 covers the circuit board 122, or covers part of the metal shell 121, mainly covers the connection end of the metal shell 121 and the circuit board 122, so as to protect the electronic components on the circuit board 122 and prevent leakage. In addition, the first insulating layer 13 extends onto the metal shell 121 to ensure that the circuit board 122 is completely covered to improve insulation.

[0037] Furthermore, the metal shell 121 includes a connecting portion (not shown) and a fixing portion (not shown), and part of the circuit board 122 extends from the fixing portion, the connecting portion is used to connect to the charging socket of the electronic device, and the fixing portion is used to fix the position of the circuit board 122. The first insulating layer 13 is covered on the fixing portion and the circuit board 122 to prevent the circuit board 122 from leaking electricity from the metal shell 121 to the outside world, causing safety hazards.

[0038] Furthermore, a portion of the first insulating layer 13 located above the metal shell 121 is provided with a protrusion 131, which is provided at the end 152 of the first insulating layer 13 to limit the movement of the metal sleeve 14 away from the wire body 11. It should be noted that the above here refers to the outer surface of the metal shell 121.

[0039] In one embodiment, if Figure 1 to Figure 2As shown, since the first insulating layer 13 covers part of the wire body 11, the first insulating layer 13 is generally formed by injection molding. If the positions of the circuit board 122 and the wire body 11 are not aligned before injection molding, the two will be offset. If the length direction of the wire body 11 and the length direction of the circuit board 122 are not in the same straight line, it will affect the fitting of the outer metal sleeve 14; then the first insulating layer 13 is provided with a first positioning portion 132 on the portion of the wire body 11 covered by the first insulating layer 13, and the first positioning portion 132 is provided on both sides of the wire body 11 in the length direction. Similarly, in order to locate the position of the circuit board 122 so that the circuit board 122 does not deviate from the preset position, the first insulating layer 13 is formed with a second positioning portion 133 on both sides of the length direction of the corresponding circuit board 122. During the injection molding process, the circuit board 122 and the wire body 11 are fixed and limited by positioning pins, and then the first insulating layer 13 is formed by injection molding through an injection molding machine. It can be understood that the second positioning portion 133 and the first positioning portion 132 are avoidance positions of the positioning pins, which can be avoidance holes or avoidance grooves, etc.

[0040] In one embodiment, the metal sleeve 14 is provided with a first through hole 141 and a second through hole (not shown) that are interconnected at opposite ends in the length direction. The first through hole 141 is arranged close to the plug assembly 12, and the second through hole is arranged close to the wire body 11. The aperture of the first through hole 141 is larger than the aperture of the second through hole, forming a funnel-like structure. The aperture of the second through hole is the same as the diameter of the wire body 11, so that the metal sleeve 14 is not easy to shake on the wire body 11. After the metal sleeve 14 is pulled to a certain position on the wire body 11, the metal sleeve 14 will no longer move. It should be noted that the apertures of the first through hole 141 and the second through hole are both the maximum radial dimensions of the through hole. For example, if the first through hole 141 is elliptical, the aperture is the maximum diameter of the ellipse; if the second through hole is circular, the aperture is the diameter of the circle. When assembling the data cable 10, the metal sleeve 14 is firstly sleeved on the wire body 11, and then the two ends of the wire body 11 are connected to the circuit board 122, and then the first insulating layer 13 is injection molded. The first through hole 141 is close to the plug assembly 12, and the metal sleeve 14 needs to be pulled to a position where the metal sleeve 14 can cover the first insulating layer 13. Because the width of the circuit board 122 is greater than the diameter of the wire body 11, the aperture of the second through hole needs to be greater than the aperture of the first through hole 141, so that the metal sleeve 14 can be sleeved on the first insulating layer 13. Due to the protrusion 131 provided on the first insulating layer 13, the metal sleeve 14 can be restricted from moving away from the wire body 11, ensuring that the metal sleeve 14 is fixed at a specific position.

[0041] In one embodiment, a second insulating layer 15 is also sleeved on the outer layer of the metal sleeve 14, and the second insulating layer 15 completely wraps the metal sleeve 14 in the second insulating layer 15. The second insulating layer 15 is usually a soft material that can be bent and restored to its original shape, such as a silicone material, so that the end 152 of the second insulating layer 15 in contact with the wire body 11 is not easy to crack after being pulled. If the second insulating layer 15 is a hard material, it is easy to break the second insulating layer 15 when pulling. Since the thermal conductivity of metal is greater than that of insulating materials, the metal sleeve 14 will emit higher heat. By setting the second insulating layer 15, it can be further insulated, so that the user will not be burned when contacting the data line 10. The metal sleeve 14 is easily scratched and oxidized, so the metal sleeve 14 can be sleeved to prevent the metal from being scratched and oxidized, thereby improving the user experience. Furthermore, the second insulating layer 15 can be made of a transparent material. By spraying different colors of paint on the metal sleeve 14 and sleeved with the second insulating layer 15 of transparent material, a special visual effect is presented. The transparent material here means that other objects under the transparent material object can be seen by the naked eye through the transparent material object.

[0042] In one embodiment, the second insulating layer 15 includes an insulating body 151 and an end 152 connected thereto, the insulating body 151 covers the metal sleeve 14 to prevent the metal sleeve 14 from being scratched, and the end 152 covers the wire body 11 to prevent the wire body 11 from being pulled off the circuit board 122 and broken. The shape of the second insulating layer 15 matches and corresponds to the shape of the metal sleeve 14.

[0043] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
