Description

Technical Field

[0001] This utility model relates to the technical field of HDMI cable manufacturing equipment, and in particular to a twisted wire length adjustment device for HDMI cables. Background Technology

[0002] An HDMI cable contains multiple conductors, typically including two core wires twisted together. During the twisting process, an unwinding device releases the two core wires separately, and then a twisting device twists them together. If the wire lengths are inconsistent, the two twisted core wires will be of different lengths, affecting signal transmission quality. Current technology lacks appropriate adjustment mechanisms along the cable path to regulate the core wire lengths. Utility Model Content

[0003] This invention provides a twisted wire length adjustment device for HDMI cables, which can adjust the routing length of two core wires to be twisted, shorten the length difference between the two core wires, and improve the signal transmission quality of the HDMI cable.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model provides a twisted cable length adjustment device for an HDMI connector, comprising two parallel side plates. Each side plate has an adjustment assembly, a first wire assembly, and a second wire assembly on its inner surface. The adjustment assembly includes an adjustment base, a servo motor, and an adjustment wheel. The adjustment base is fixed to the side plate, and the adjustment wheel is rotatably connected to the adjustment base. The servo motor is fixed to the adjustment base and connected to the adjustment wheel. The first wire assembly includes a first wire wheel, and the second wire assembly includes a second wire wheel. Two core wires to be twisted pass over the adjustment wheel, the first wire wheel, and the second wire wheel on the two side plates, respectively.

[0006] In some embodiments, the second conductor assembly further includes a second conductor seat and a slider. The second conductor seat is fixed to the side plate, and the slider is slidably connected to the second conductor seat in a vertical direction. The second conductor wheel is rotatably connected to the slider. The core wire to be stranded is used to pass around the second conductor wheel from the bottom of the second conductor wheel. A detection component is also fixed to the side plate. The detection component is located on one side of the second conductor assembly and is used to detect the tension of the core wire.

[0007] In some embodiments, a downwardly extending connecting block is fixed on the slider, and a test surface is provided on the side of the connecting block near the detection component. The test surface is inclined relative to the vertical direction. The detection component includes a detection seat fixed on the side plate and a detection sensor fixed on the detection seat. The detection sensor is used to detect the lateral distance from itself to the test surface.

[0008] In some embodiments, the detection sensor is a reflective distance sensor.

[0009] In some embodiments, the second wire assembly further includes a guide rod disposed on the second wire seat, the guide rod extending in a vertical direction, the slider having a through hole, the guide rod passing through the through hole and being slidable along the through hole.

[0010] In some embodiments, the second wire assembly further includes two connecting plates, which are respectively fixed to the upper and lower ends of the second wire seat, and the two ends of the guide rod are respectively fixedly connected to the two connecting plates.

[0011] In some embodiments, the guide rod is fitted with two springs, one spring being located above the slider and the other spring being located below the slider. The two ends of the spring located above the slider abut against the connecting plate at the upper end of the slider and the second guide seat, respectively, and the two ends of the spring located below the slider abut against the connecting plate at the lower end of the slider and the second guide seat, respectively.

[0012] In some embodiments, the first wire assembly further includes a first wire seat fixed to a side plate, and the first wire wheel is rotatably connected to the first wire seat.

[0013] This invention has at least the following beneficial effects: The two core wires to be twisted in this invention pass through the adjusting wheel, the first guide wheel and the second guide wheel on the two side plates respectively. When the length of one core wire is too large, the servo motor corresponding to that core wire drives the adjusting wheel to reduce its speed, thereby reducing the length of that core wire and making the lengths of the two core wires closer. Therefore, this invention can adjust the length of the two core wires to be twisted, shorten the length difference between the two core wires and improve the signal transmission quality of the HDMI cable.

[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0026] An embodiment of this utility model provides a twisted wire length adjustment device for an HDMI connector cable, such as... Figure 1-3 As shown, the device includes two parallel side plates 100. Each side plate 100 has an adjustment assembly 200, a first conductor assembly 300, and a second conductor assembly 400 on its inner surface. Since two core wires 10 are twisted together, each core wire 10 uses the adjustment assembly 200, the first conductor assembly 300, and the second conductor assembly 400 on one side plate 100 respectively. The adjustment assemblies 200, the first conductor assemblies 300, and the second conductor assemblies 400 on both side plates 100 have identical structures and dimensions, ensuring that the routing lengths of the two core wires 10 remain the same.

[0027] The adjustment assembly 200 includes an adjustment base 230, a servo motor 220, and an adjustment wheel 210. The adjustment base 230 is fixed to the side plate 100, the adjustment wheel 210 is rotatably connected to the adjustment base 230, and the servo motor 220 is fixed to the adjustment base 230 and connected to the adjustment wheel 210. The first wire assembly 300 includes a first wire wheel 310, and the second wire assembly 400 includes a second wire wheel 410. Two core wires 10 to be stranded pass over the adjustment wheel 210, the first wire wheel 310, and the second wire wheel 410 on the two side plates 100, respectively. The adjustment wheel 210, the first wire wheel 310, and the second wire wheel 410 are used for routing the core wires 10 and also to give the core wires 10 a certain tension. During normal use, the servo motors 220 on the two side plates 100 drive the two adjusting wheels 210 to rotate synchronously, thereby driving the core wires 10 to run at the same running speed. However, due to the differences in the core wires 10 themselves and the precision error of the equipment, after a period of use, the running lengths of the two core wires 10 will inevitably differ. When the difference in the running lengths of the two core wires 10 exceeds a threshold, the servo motor 220 corresponding to the core wire 10 with the longer running length drives its adjusting wheel 210 to reduce its speed, slowing down the running speed of the core wire 10, thereby reducing the running length of the core wire 10 and making the running lengths of the two core wires 10 closer. Therefore, this embodiment can adjust the running lengths of the two core wires 10 to be twisted, shorten the length difference between the two core wires 10, and improve the signal transmission quality of the HDMI cable.

[0028] It should be noted that a detection mechanism for detecting the length of the core wire 10 can be set on the routing path of the core wire 10. Both the detection mechanism and the servo motor 220 are connected to the controller. When the detection mechanism detects that the difference in the routing length of the two core wires 10 exceeds a threshold, the controller sends a control command to the servo motor 220 corresponding to the core wire 10 with the longer routing length, so that the servo motor 220 drives its adjusting wheel 210 to reduce its speed, thereby adjusting the routing length. The detection mechanism may include an encoder, for example, connecting the encoder to the first guide wheel 310. The rotation angle of the first guide wheel 310 is proportional to the routing length. The routing length of the corresponding core wire 10 can be obtained by detecting the rotation angle of the first guide wheel 310.

[0029] In some embodiments, the second wire assembly 400 further includes a second wire seat 420 and a slider. The second wire seat 420 is fixed to the side plate 100, the slider is slidably connected to the second wire seat 420 in the vertical direction, and the second wire wheel 410 is rotatably connected to the slider, thus the second wire wheel 410 can slide in the vertical direction. The core wire 10 to be stranded is used to pass around the second wire wheel 410 from the bottom of the second wire wheel 410, and the tension generated by the core wire 10 will pull the second wire wheel 410 upward. A detection component 500 is also fixed on the side plate 100. The detection component 500 is located on one side of the second wire assembly 400 and is used to detect the tension of the core wire 10. This allows the tension of the two core wires 10 to be known, thereby facilitating the adjustment of the tension of the core wires 10 so that the tension of the two core wires 10 remains the same.

[0030] Furthermore, a downwardly extending connecting block 430 is fixed on the slider. A measured surface 431 is provided on the side of the connecting block 430 near the detection assembly 500, and the measured surface 431 is inclined relative to the vertical direction. The detection assembly 500 includes a detection seat 510 fixed on the side plate 100 and a detection sensor 520 fixed on the detection seat 510. The detection sensor 520 is used to detect the lateral distance from the sensor to the measured surface 431. When the tension of the core wire 10 changes, the second guide wheel 410 moves vertically, and correspondingly, the connecting block 430 also moves vertically. Since the measured surface 431 is inclined relative to the vertical direction, as the connecting block 430 moves, the distance from the back side 431 to the detection sensor 520 changes. Therefore, the tension of the core wire 10 is reflected by the lateral distance from the detection sensor 520 to the measured surface 431.

[0031] by Figure 2 For example, when the tension of the core wire 10 increases, the second guide wheel 410 moves upward, and the detection sensor 520 detects that the lateral distance between it and the measured surface 431 is increasing. Conversely, when the tension of the core wire 10 decreases, the second guide wheel 410 moves downward, and the detection sensor 520 detects that the lateral distance between it and the measured surface 431 is decreasing.

[0032] Furthermore, the detection sensor 520 is a reflective distance sensor, specifically a photoelectric sensor, which emits infrared light laterally toward the measured surface 431 to detect its lateral distance to the measured surface 431.

[0033] In some embodiments, the second wire assembly 400 further includes a guide rod 440 disposed on the second wire seat 420. The guide rod 440 extends in a vertical direction, and the slider is provided with a through hole. The guide rod 440 passes through the through hole and can slide along the through hole, so that the slider can slide in a vertical direction. The guide rod 440 guides the slider so that its movement direction is not easily deviated and it slides stably in a vertical direction.

[0034] Furthermore, the second wire assembly 400 also includes two connecting plates, which are designated as an upper connecting plate 451 and a lower connecting plate 452 for easy identification. The upper connecting plate 451 is fixed to the upper end of the second wire seat 420, and the lower connecting plate 452 is fixed to the lower end of the second wire seat 420. The two ends of the guide rod 440 are fixedly connected to the upper connecting plate 451 and the lower connecting plate 452, respectively. The upper connecting plate 451 and the lower connecting plate 452 not only support and fix the guide rod 440, but also maintain a certain distance between the guide rod 440 and the second wire seat 420, providing space for the movement of the slider and facilitating smooth sliding of the slider.

[0035] Furthermore, two springs are fitted onto the guide rod 440. For easy distinction, the two springs are designated as an upper spring 461 and a lower spring 462. The upper spring 461 is located above the slider, and the lower spring 462 is located below the slider. The two ends of the upper spring 461 abut against the slider and the upper connecting plate 451, respectively, while the two ends of the lower spring 462 abut against the slider and the lower connecting plate 452, respectively. The lower spring 462 provides support to the slider, preventing the slider and the second guide rail seat 420 from falling onto the lower connecting plate 452 under their own weight. When the tension of the core wire 10 changes, the upper spring 461 and the lower spring 462 can adaptively provide elastic force to maintain the force balance of the second guide rail wheel 410, keeping it relatively stable.

[0036] In some embodiments, the first wire assembly 300 further includes a first wire seat 320, which is fixed on the side plate 100. The first wire wheel 310 is rotatably connected to the first wire seat 320, and the first wire seat 320 is used to fix the first wire wheel 310.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
