Description

Technical Field

[0001] The present invention relates to the field of data cables, and particularly to a data cable and a manufacturing method thereof. Background Art

[0002] The function of a data cable is to connect between devices to achieve data transfer or communication purposes. Commonly, it is used to connect between a computer and a mobile device, which is a path tool for connecting a computer and a mobile device to transfer files such as videos, ringtones, and pictures, and is also used to connect between a mobile device and a charging device for charging the mobile device.

[0003] An existing data cable is provided with a plurality of light-emitting components arranged along the data cable. When it is turned on, the light-emitting components emit light. However, the light emitted by such a data cable is point light. Even if the point lights are densely arranged, the lighting effect is not very ideal, and its lighting uniformity is also limited. Summary of the Invention

[0004] The first object of the present invention is to provide a data cable with uniform lighting.

[0005] The second object of the present invention is to provide a manufacturing method of the above data cable.

[0006] To achieve the first object of the present invention, the present invention provides a data cable, including a laser device, a circuit board, a data connection line, a wire tube, a data interface, and a sleeve. The laser device includes a laser diode and an optical fiber light guide component. The input end of the optical fiber light guide component is butted against the output end of the laser diode. The laser diode is used to output light to the optical fiber light guide component. The laser diode is soldered to the circuit board. The data connection line is soldered to the circuit board. The wire tube is provided with a through hole along the extending direction. Both the optical fiber light guide component and the data connection line extend into the through hole. The data interface is soldered on the circuit board. The sleeve is sleeved outside the ends of the laser diode, the optical fiber light guide component, the data interface, the circuit board, the end of the data connection line, and the wire tube. A fixing glue component is filled between the sleeve, the ends of the laser diode, the optical fiber light guide component, the data interface, the circuit board, the end of the data connection line, and the wire tube.

[0007] As can be seen from the above solution, the light source of the data cable in this case uses a laser diode, and an optical fiber light guide component is used for optical fiber light guiding. The optical fiber light guide component passes through the wire tube, and then realizes uniform lighting of the wire tube, which improves the overall aesthetics of the data cable with uniform lighting. Moreover, each device is arranged in the sleeve and filled with a fixing glue component, thereby improving the assembly stability and use stability of the device, and also facilitating the miniaturization of the connection end.

[0008] A further solution is that the laser diode adopts a single-row straight plug-in package, and the output end and the pins of the laser diode are respectively located on opposite sides.

[0009] A further solution is that the package of the laser diode, the pins of the laser diode, and the circuit board all extend in the same direction.

[0010] A further solution is that the package of the laser diode is located outside the first end of the circuit board, the pins of the laser diode are soldered to the first end of the circuit board, the data interface is located at the second end of the circuit board, and the laser diode and the data interface are respectively located on opposite sides of the circuit board.

[0011] As can be seen from the above, through the flat single in-line package, the package, pins, and circuit board of the laser diode all extend in the same direction, making the layout of the entire circuit device also flat. With the cooperation of the sleeve and the fixing glue, the connection end and the connecting wire are flattened and miniaturized.

[0012] A further solution is that the fixing glue assembly includes a first fixing glue, and the first fixing glue wraps around the ends of the laser diode, the optical fiber light guiding assembly, the data interface, the circuit board, the ends of the data connecting wire, and the end of the wire tube.

[0013] As can be seen from the above, the ends of the laser diode, the optical fiber light guiding assembly, the data interface, the circuit board, the ends of the data connecting wire, and the end of the wire tube are placed in a jig for injection molding and fixing, that is, the first fixing glue is used for positioning first to stably maintain the connection of each device.

[0014] A further solution is that the fixing glue assembly further includes a second fixing glue. The first fixing glue is located inside the sleeve, and the second fixing glue is filled between the sleeves where the first fixing glue is located.

[0015] As can be seen from the above, then the sleeve is sleeved outside the first fixing glue, and the sleeve is fixed by the second fixing glue, thereby optimizing the appearance and the operating feel, and also providing good protection.

[0016] A further solution is that a circumferential groove is provided along the inner wall of the sleeve, a positioning groove is provided on the surface of the first fixing glue, and the second fixing glue is also filled in the circumferential groove and the positioning groove.

[0017] A further solution is that a positioning protrusion is also provided on the surface of the first fixing glue, and between the positioning protrusion and the circumferential groove, the positioning protrusion is adjacent to the side wall of the circumferential groove.

[0018] As can be seen from the above, when filling the second fixing glue, through the mutual cooperation of the circumferential groove, the positioning protrusion, and the positioning groove, the connection stability is improved.

[0019] To achieve the second objective of the present invention, the present invention provides a method for manufacturing a data cable, where the data cable is the data cable of the above solution; the fixing glue assembly includes a first fixing glue and a second fixing glue; the control method includes: placing a laser diode, an optical fiber light guiding assembly, a data interface, a circuit board, a data connection line, and a wire tube in a jig, injecting the first fixing glue into the jig so that the first fixing glue wraps around the ends of the laser diode, the optical fiber light guiding assembly, the end of the data interface, the circuit board, the end of the data connection line, and the end of the wire tube; placing the first fixing glue in a sleeve; and filling the second fixing glue between the sleeves where the first fixing glue is located.

[0020] A further solution is that the fixing glue assembly includes a third fixing glue; before the laser diode and the optical fiber light guiding assembly are placed in the jig, the control method further includes: fixing the relative position between the input end of the optical fiber light guiding assembly and the output end of the laser diode through the third fixing glue.

[0021] As can be seen from the above, first, the third fixing glue can be used to stabilize the connection between the input end of the optical fiber light guiding assembly and the output end of the laser diode. Then, the first fixing glue is used to fix the devices first. Finally, the sleeve is put on and the second fixing glue is filled to fix the sleeve, making the entire data cable connection stable.

[0031] Referring to Figure 1 , Figure 1 Figure, which is a structural diagram of data line 1. Data line 1 includes a line tube 11 and terminal ends 12 and 2 located at both ends of line tube 11. Below, the structure of terminal end 2 will be mainly described. Referring to Figures 2 to 4 Figure, a laser device, a circuit board 21, a data connection line, a data interface 22, and a sleeve 24 are provided at terminal end 2. The laser device includes a laser diode 31 and an optical fiber light guiding component 32. The laser diode 31 adopts a single-row straight plug package 311. An installation groove 312 is provided in the package 311. A light emitting mechanism of the laser diode 31 is provided in the installation groove 312. The opening of the installation groove 312 is the output end of the laser diode 31. The output end of the laser diode 31 and the pin 313 of the laser diode 31 are respectively located on opposite sides. The package 311 of the laser diode 31, the pin 313 of the laser diode 31, the circuit board 21, and the line tube 11 all extend in the same direction, and extend horizontally in the state shown in the attached drawing.

[0032] The package 311 of the laser diode 31 is located outside the first end 211 of the circuit board 21. The pin 313 of the laser diode 31 is welded to the first end 211 of the circuit board 21. The data interface 22 is welded to the second end 212 of the circuit board 21. The laser diode 31 and the data interface 22 are respectively located on opposite sides of the circuit board 21. The package 311 of the laser diode 31, the circuit board 21, and the data interface 22 partially overlap in the extending direction of the circuit board 21, making the layout of the entire device more flattened.

[0033] The optical fiber light guiding component 32 includes a ferrule 323, a core 321, and a cladding 322. The cladding 322 is sleeved outside the core 321. The ferrule 323 is provided with a positioning hole penetrating therethrough. The input end of the core 321 passes through the ferrule 323. The ferrule 323 is opposite to the output end of the laser diode 31. The input end of the core 321 is docked with the output end of the laser diode 31. The laser diode 31 is used to output light to the core 321. A fixing glue 33 is bonded between the ferrule 323 and the output end of the laser diode 31. The fixing glue 33 fixes the relative position between the input end of the optical fiber light guiding component 32 and the output end of the laser diode 31.

[0034] The data connection line (not shown) is welded to the circuit board 21. The line tube 11 is provided with a through hole 111 along the extending direction. Both the optical fiber light guiding component 32 and the data connection line extend into the through hole 111. The data connection line is connected between terminal end 2 and terminal end 12 and realizes corresponding data transmission.

[0035] Referring to Figure 5 andFigure 6 After the above-mentioned devices are connected and installed, the laser diode 31, the optical fiber light guide assembly 32, the data interface 22, the circuit board 21, the data connection line, and the wire tube 11 are placed in a jig, and the fixing glue 23 is injected into the jig so that the fixing glue 23 wraps around the ends of the laser diode 31, the optical fiber light guide assembly 32, the end of the data interface 22, the circuit board 21, the end of the data connection line, and the end of the wire tube 11.

[0036] Subsequently, the fixing glue 23 is placed inside the sleeve 24. The sleeve 24 is made of aluminum material, is arranged in a flat ring shape, and is provided with mounting holes penetrating therethrough. The above-mentioned devices and the fixing glue 23 are placed inside the sleeve 24 so that the sleeve 24 sleeves around the ends of the laser diode 31, the optical fiber light guide assembly 32, the end of the data interface 22, the circuit board 21, the end of the data connection line, and the end of the wire tube 11. A plurality of annular grooves 241 are arranged along the circumferential direction on the inner wall of the sleeve 24. A plurality of positioning grooves 232 are arranged on the surface of the fixing glue 23. The plurality of positioning grooves 232 are distributed at different positions. A positioning protrusion 231 is also arranged on the surface of the fixing glue 23. Between the positioning protrusion 231 and the annular groove 241, the positioning protrusion 231 is adjacent to the side wall of the annular groove 241.

[0037] Refer to Figure 7 and Figure 8 Then, the sleeve 24 and each device inside it are placed into another jig, and the fixing glue 25 is added to the jig so that the fixing glue 25 fills the space between the fixing glue 23 within the sleeve 24, and the fixing glue 25 also fills the annular groove 241 and the positioning groove 232. The fixing glue 25 also extends outside the wire tube 11 and outside the sleeve 24. The above-mentioned fixing glue 23, fixing glue 25, and fixing glue 33 constitute the fixing glue assembly of this solution.

[0038] When the data interface 22 of the terminal 2 is powered on or connected, in addition to the data connection line realizing data transmission, the laser diode 31 outputs light to the fiber core 321, so that the ambient light and the shaping light are conducted along the fiber core 321 and uniformly leak outside on the cladding. A part of the wire tube 11 can be made of a light-transmitting material, so that the wire tube emits light uniformly.

[0039] Embodiment of the light-emitting device. The light-emitting device can be the above-mentioned data line, or can be devices such as lawn lamps, ambient lights, and light strips. The light-emitting device includes a laser device as in the above solution, and the laser device includes the above-mentioned laser diode and the optical fiber light guide assembly.

[0040] As can be seen from the above, the light source of the data cable in this case uses a laser diode, and an optical fiber light guiding component is used for optical fiber light guiding. The optical fiber light guiding component passes through the wire tube, and then realizes uniform light emission of the wire tube, so that the uniform light emission of the data cable improves the overall aesthetics. In addition, each device is arranged in a sleeve and filled with a fixing glue component, thereby improving the assembly stability and use stability of the device and also facilitating the miniaturization of the connection end.

[0041] In addition, the light source uses a laser diode, and an optical fiber light guiding component is used for optical fiber light guiding. The optical fiber light guiding component passes through the wire tube, and then realizes uniform light emission of the wire tube, so that the uniform light emission of the laser device or the lighting device improves the overall aesthetics. Moreover, the package, pins and circuit board of the laser diode are all arranged in the same direction and extended, so that the layout of the entire lighting device is also flat, realizing the flattening and miniaturization of the device.
