[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0030] The utility model embodiment provides a data line, such as Figures 1 to 4 As shown, the data line includes a connecting line 10, a circuit board 20, a light-transmitting layer 30, a rubber coating layer 40, a metal shell 50 and an electrical connection terminal 60.

[0031] The connection line 10 can transmit electrical energy or data.

[0032] The circuit board 20 is electrically connected to the connecting line 10. The circuit board 20 is provided with a first light-emitting component 70 and a second light-emitting component, which are respectively arranged on the front and back of the circuit board 20. The first light-emitting component 70 and the second light-emitting component can both display the working status of the data line.

[0033] The light-transmitting layer 30 is coated on the outer periphery of the circuit board 20. The light emitted by the first light-emitting component 70 and the second light-emitting component on the circuit board 20 can all pass through the light-transmitting layer 30.

[0034] The encapsulation layer 40 is coated on the outer periphery of the light-transmitting layer 30, and the encapsulation layer 40 is provided with a first opening 41 and a second opening corresponding to the positions of the first light-emitting component 70 and the second light-emitting component. The first light-emitting component 70 and the second light-emitting component can transmit light outward through the first opening 41 and the second opening respectively.

[0035] The metal shell 50 is disposed on the outer periphery of the rubber layer 40, and the metal shell 50 is provided with a first light-transmitting hole 51 and a second light-transmitting hole 52 corresponding to the first opening 41 and the second opening, respectively. The user can observe the working status of the data line through the first light-transmitting hole 51 and / or the second light-transmitting hole 52.

[0036] The electrical connection terminal 60 is electrically connected to the circuit board 20, and partially passes through the light-transmitting layer 30 and the rubber coating layer 40 and exposes the metal housing 50. The electrical connection terminal 60 can be connected to an electronic device to realize the transmission of power or data between the data line and the electronic device, or connected to a power supply device to realize the transmission of power or data between the data line and the electronic device. The electrical connection terminal 60 can be one of a USB-A terminal, a USB-B terminal, a type-C terminal, a lighting terminal, and a MagSafe terminal.

[0037] The present application realizes the encapsulation and fixation of the data line interface structure by coating the light-transmitting layer 30 on the periphery of the circuit board 20, coating the rubber layer 40 on the periphery of the light-transmitting layer 30, and arranging the metal shell 50 on the periphery of the rubber layer 40. The stacked structure of the light-transmitting layer 30, the rubber layer 40 and the metal shell 50 is stable, which can reduce the possibility of loosening of the electrical connection terminal 60 and reduce safety hazards. In addition, light-emitting components are arranged on the front and back of the circuit board 20, and the user can observe the working status of the data line through the front or back of the data line, and the data line is more visible.

[0038] Among them, the first light-emitting component 70 and the second light-emitting component are separated on the front and back of the circuit board 20. When the user places the data cable, he does not need to consider whether the front or back of the circuit board 20 is facing up, and the working status of the data cable can be observed, which is convenient to use.

[0039] refer to Figure 3 and Figure 4 In this embodiment, a first limiting portion 42 and a second limiting portion 43 are provided on the rubber coating layer 40, and a third limiting portion 53 and a fourth limiting portion 54 are provided on the metal shell 50. The third limiting portion 53 abuts against the first limiting portion 42, and the fourth limiting portion 54 abuts against the second limiting portion 43, so as to clamp the rubber coating layer 40 in the metal shell 50.

[0040] By arranging a first limiting portion 42 and a second limiting portion 43 on the rubber coating layer 40, and arranging a third limiting portion 53 and a fourth limiting portion 54 on the metal shell 50, the rubber coating layer 40 and the metal shell 50 cooperate with each other, the rubber coating layer 40 is clamped by the metal shell 50, and the structure between the rubber coating layer 40 and the metal shell 50 is stable and not easy to loosen.

[0041] Specifically, the first limiting portion 42 includes a first protrusion 421 disposed on the outer surface of the rubber coating 40 , and the third limiting portion 53 includes a limiting groove 531 disposed on the inner surface of the metal shell 50 . The first protrusion 421 is received in the limiting groove 531 .

[0042] The first protrusion 421 cooperates with the limiting groove 531 and is inserted into the limiting groove 531 , which can prevent displacement between the rubber coating layer 40 and the metal shell 50 , thereby making the structure between the rubber coating layer 40 and the metal shell 50 more stable.

[0043] In other embodiments, the third limiting portion 53 of the metal shell 50 may include a first protrusion 421 protruding from the inner surface of the metal shell 50, and the first limiting portion 42 of the rubber layer 40 may include a limiting groove 531 provided on the outer surface of the rubber layer 40, which can also prevent displacement between the rubber layer 40 and the metal shell 50.

[0044] Furthermore, the second limiting portion 43 includes a limiting end surface 431 disposed on the outer periphery of the rubber coating 40 , and the fourth limiting portion 54 includes a second protrusion 541 disposed on the inner surface of the protruding metal shell 50 , and the second protrusion 541 abuts against the limiting end surface 431 .

[0045] The second protrusion 541 abuts against the limiting end surface 431 on the outer periphery of the rubber coating layer 40, limiting the rubber coating layer 40 in the metal shell 50, which can make the structure between the metal shell 50 and the rubber coating layer 40 more stable. The metal shell 50 can also protect the rubber coating layer 40 to prevent the rubber coating layer 40 from being scratched, thereby increasing the service life of the data cable.

[0046] Specifically, the setting of the upper limit groove 531 and the second protrusion 541 on the metal shell 50 and the setting of the first protrusion 421 and the limiting end face 431 on the rubber coating layer 40 can limit the rubber coating layer 40 in the metal shell 50, prevent the rubber coating layer 40 and the metal shell 50 from shifting, and protect the rubber coating layer 40.

[0047] refer to Figure 3 and Figure 4 In this embodiment, a limiting step 31 is provided on the light-transmitting layer 30, and a supporting portion 44 is provided on the rubber-coated layer 40, and the supporting portion 44 is in contact with the limiting step 31. By providing the limiting step 31 and the supporting portion 44 to abut against each other, displacement between the light-transmitting layer 30 and the rubber-coated layer 40 is prevented, so that the light-transmitting layer 30 and the rubber-coated layer 40 are more stable.

[0048] refer to Figure 3 and Figure 4 In this embodiment, the light-transmitting layer 30 is provided with a first groove 32 and a second groove corresponding to the positions of the first light-emitting component 70 and the second light-emitting component respectively.

[0049] By setting the first groove 32 and the second groove, an avoidance window can be provided for the processing of the rubber coating layer 40, so that the first opening 41 and the second opening on the rubber coating layer 40 can be easily aligned. At the same time, the thickness of the position corresponding to the first groove 32 and the second groove on the light-transmitting layer 30 is relatively small, and the light is less obstructed and scattered when propagating at this position, so that it can pass through the light-transmitting layer 30 more effectively, and the light transmission effect is better.

[0050] refer to Figures 1 to 4 In this embodiment, the data line further includes a limiting protective cover 80 , a portion of the connecting line 10 passes through the limiting protective cover 80 and is electrically connected to the circuit board 20 , and the limiting protective cover 80 and the rubber coating 40 are integrally formed.

[0051] The limiting protective cover 80 is integrally formed with the rubber coating 40 , which can fix the end of the connecting line 10 electrically connected to the circuit board 20 , and prevent the end of the connecting line 10 electrically connected to the circuit board 20 from excessive bending, thereby improving the service life of the data line.

[0052] In addition, the integral molding of the limiting protective cover 80 and the rubber coating layer 40 has the following advantages: a firm bond is formed between the limiting protective cover 80 and the rubber coating layer 40, and the overall packaging and fixing effect is better; the assembly process of the data cable is reduced, the production efficiency is improved, and the manufacturing cost of the data cable is reduced.

[0053] Furthermore, the metal shell 50 may be provided with an avoidance groove 55, and the position limiting protective cover 80 is partially accommodated in the avoidance groove 55. The setting of the avoidance groove 55 has a certain limiting effect on the position limiting protective cover 80, thereby preventing the position limiting protective cover 80 from shaking relative to the metal shell 50.

[0054] refer to Figure 3 In this embodiment, the first light-emitting component 70 and / or the second light-emitting component includes a first LED lamp 71 and a second LED lamp 72 arranged side by side on the circuit board 20.

[0055] LED (Light Emitting Diode) lamp is a semiconductor device, a solid-state light source that can directly convert electrical energy into light energy. LED lamps have the following significant advantages: high efficiency and energy saving, LED lamps have high energy conversion efficiency and can convert most of the electrical energy into light energy; long life, LED lamps have a long service life; fast response, LED lamps have fast opening and closing time, and can instantly reach full brightness or full darkness without preheating; miniaturization and flexibility, LED lamps are small in size and can be made into various shapes and sizes to meet different application requirements. In addition, LED lamps can also achieve dimming and color changes by adjusting current and controlling electronic devices, providing more lighting effect options.

[0056] The first LED light 71 and the second LED light 72 arranged side by side can be lights of the same color, which jointly display the working status of the data line, and the light display effect is clearer. For example, the first LED light 71 and the second LED light 72 can both be lights of red, yellow, green or blue colors. When the data line is in the charging state of the external device, the first LED light 71 and the second LED light 72 flash. When the data line is fully charged in the external device, the first LED light 71 and the second LED light 72 are always on.

[0057] The first LED light 71 and the second LED light 72 arranged side by side can also be lights of different colors, respectively indicating that the data line is working in different states. For example, the first LED light 71 is red, and the second LED light 72 is green. When the data line is in the external device charging state, the first LED light 71 is on, and the second LED light 72 is off. When the data line is fully charged, the first LED light 71 is off, and the second LED light 72 is on.

[0058] refer to Figure 3 In this embodiment, an avoidance notch 21 is provided on the circuit board 20 , and the connecting wire 10 is accommodated in the avoidance notch 21 and is electrically connected to the electrode on the circuit board 20 .

[0059] By providing an avoidance notch 21 for avoiding the connecting wire 10 on the circuit board 20, the connecting wire 10 occupies a smaller space after being connected to the circuit board 20, and the structure is compact, which is more conducive to the miniaturization of the data line. When designing the electrode of the circuit board 20, the electrode can be arranged at a position close to the avoidance notch 21, so that the electrical connection terminal 60 and the circuit board 20 are convenient for electrical connection and assembly.

[0060] In this embodiment, the material of the metal shell 50 is one of aluminum, copper, and zinc alloy. Preferably, the metal shell 50 is aluminum. Aluminum as the material of the metal shell 50 has the following advantages: it has a low density and weight, making the data cable light and easy to carry; it has good strength and durability, reducing the possibility of wear of the data cable; it has good thermal conductivity, and can effectively conduct heat to the outer surface of the metal shell 50, improve the heat dissipation effect, and maintain a stable working temperature of the data cable; it has good plasticity, and aluminum can be made into shells of various shapes and structures through die-casting, extrusion and other processing processes to meet the needs of different data cable interface designs; aluminum has a metallic luster and texture, and is more beautiful in appearance, which can improve the overall quality of the data cable and user experience.
