Abstract
Description
Technical Field
[0001] This utility model relates to the field of data cable technology, and in particular to an HDMI data cable. Background Technology
[0002] An HDMI cable is a fully digital audio and video transmission cable used to simultaneously transmit high-definition video and multi-channel audio signals between devices. It supports lossless transmission and eliminates the need for a separate audio cable, simplifying device connection. It is widely compatible with various devices such as TVs, computers, game consoles, projectors, and digital cameras. HDMI uses fully digital signal transmission, which, compared to analog signals, is less susceptible to external electromagnetic interference, effectively avoiding signal attenuation, blurry images, and stuttering, ensuring stable audio and video transmission.
[0003] Because HDMI cables are typically long, they easily become tangled and knotted when not in use, affecting aesthetics and creating inconvenience for future use, requiring time to untangle. Furthermore, when cables are pulled, bent, or left in a tangled state for extended periods, internal wires may break, the outer sheath may be damaged, affecting data transmission performance or even rendering the cable unusable. During insertion and removal of the connector, dust can enter the connector structure. Since dust is often conductive, accumulation can create conductive paths between adjacent pins, leading to short circuits, circuit malfunctions, damage to electronic devices, and even safety issues. Therefore, this paper proposes an HDMI cable to address these problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an HDMI data cable, which aims to improve the problems of HDMI data cables being easily tangled and knotted when placed arbitrarily, potentially damaging the internal wires and outer sheath when pulled or bent, and allowing dust to enter the connector when plugging and unplugging.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an HDMI data cable, including a shell, a housing fixedly connected inside the shell, a storage shaft rotatably connected inside the housing, a coil spring fixedly connected to the outside of the storage shaft, a data cable provided inside the housing, connectors fixedly connected to both ends of the data cable, a support plate fixedly connected inside the shell, and a locking component fixedly connected to the top of the support plate.
[0006] The locking assembly includes a protective shell 1, a connecting rod 1 slidably connected inside the protective shell 1, a limit block fixedly connected to the outside of the connecting rod 1, a spring 1 fixedly connected to the outside of the connecting rod 1, a protective shell 2 fixedly connected to the outside of the protective shell 1, a trapezoidal block slidably connected inside the protective shell 2, a protective shell 3 fixedly connected to the top of the protective shell 2, a connecting rod 2 slidably connected inside the protective shell 3, a fixing block fixedly connected to the top of the connecting rod 2, a spring 2 fixedly connected to the outside of the connecting rod 2, and dustproof components fixedly connected to both ends of the data cable.
[0007] As a further description of the above technical solution:
[0008] The dustproof assembly includes two dust covers, which are slidably connected to the outside of the data cable and the outside of the connector. A cover plate is rotatably connected to the outside of the dust cover, and a rotating rod is fixedly connected to the outside of the dust cover. The cover plate is rotatably connected to the outside of the rotating rod, and a torsion spring is sleeved on the outside of the rotating rod. One end of the torsion spring is fixedly connected to the outside of the dust cover, and the other end of the torsion spring is fixedly connected to the outside of the cover plate.
[0009] As a further description of the above technical solution:
[0010] The limiting block is slidably connected inside the storage shaft, and the limiting block is slidably connected inside the protective shell.
[0011] As a further description of the above technical solution:
[0012] The end of the spring away from the limiting block is fixedly connected to the outside of the protective shell.
[0013] As a further description of the above technical solution:
[0014] The first connecting rod is slidably connected inside the second protective shell, and the first connecting rod is fixedly connected to the outside of the trapezoidal block.
[0015] As a further description of the above technical solution:
[0016] The fixed block is slidably connected inside the protective shell three, the bottom of the spring two is fixedly connected to the top of the protective shell two, and the connecting rod two is slidably connected to the outside of the trapezoidal block.
[0017] As a further description of the above technical solution:
[0018] The support plate is fixedly connected to the top of the housing, and the storage shaft is rotatably connected inside the support plate.
[0019] As a further description of the above technical solution:
[0020] One end of the coil spring is fixedly connected to the outside of the housing.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, when using an HDMI cable, pressing down on the fixing block releases the locking component from the storage shaft via a linkage structure, pulling the data cable causes the storage shaft to rotate, and the coil spring unfolds to store energy; releasing the fixing block re-fixes the storage shaft, keeping the data cable stretched; after use, releasing the lock again causes the elastic restoring force of the coil spring to drive the storage shaft to rotate in the opposite direction, evenly winding the data cable back onto the storage shaft. The guide groove structure inside the housing ensures that the cable is arranged in an orderly manner, completing automatic winding, thus maintaining a clean and orderly working environment, keeping the cable in a relatively neat state when not in use, reducing the risk of damage caused by external pressure, twisting, etc., and extending the service life of the data cable.
[0023] 2. In this utility model, when using an HDMI cable, pressing the cover plate causes it to rotate. The torsion spring deforms under torsional force, stores energy, and releases a reverse torque, at which point the connector can be removed. When the cover plate stops rotating, the torsion spring remains in its current state due to the connector abutting against it. After the connector is unplugged, the torsion spring releases its elastic potential energy to drive the cover plate to quickly return to its original position to cover the interface and prevent dust. Its tight spring coil structure can reduce frictional loss and ensure a long-term stable dustproof effect, thus preventing dust from entering the device from the interface and avoiding short circuits and poor contact.

[0032] Reference Figures 1-5 The present invention provides an embodiment of an HDMI data cable, comprising a housing 1, a housing 3 fixedly connected inside the housing 1, a storage shaft 5 rotatably connected inside the housing 3, a coil spring 4 fixedly connected to the outside of the storage shaft 5, a data cable 16 disposed inside the housing 3, and connectors 19 fixedly connected to both ends of the data cable 16, a support plate 2 fixedly connected inside the housing 1, and a locking component fixedly connected to the top of the support plate 2. The housing 1 is used to protect the internal structure from damage. The housing 3 and the housing 1 are fixed together by screws.

The data cable 16 is installed inside the housing 3. The connectors 19 are used to connect to devices. The locking component is fixed inside the housing 1 by the support plate 2.
[0033] The locking assembly includes a protective shell 6, a connecting rod 8 slidably connected inside the protective shell 6, a limit block 7 fixedly connected to the outside of the connecting rod 8, a spring 9 fixedly connected to the outside of the connecting rod 8, a protective shell 10 fixedly connected to the outside of the protective shell 6, a trapezoidal block 11 slidably connected inside the protective shell 10, a protective shell 12 fixedly connected to the top of the protective shell 10, a connecting rod 14 slidably connected inside the protective shell 12, a fixing block 13 fixedly connected to the top of the connecting rod 14, and a spring 2 fixedly connected to the outside of the connecting rod 14. 15. Both ends of the data cable 16 are fixedly connected to dustproof components. The locking components are connected as one unit through the protective shell 1 6. The connecting rod 1 8 drives the limiting block 7 to slide together. The spring 1 9 is fixed on the outside of the connecting rod 1 8. The protective shell 2 10 is used to limit the sliding range of the trapezoidal block 11. The connecting rod 1 8 slides through the trapezoidal block 11. The protective shell 3 12 is used to limit the range of motion of the connecting rod 2 14. The fixing block 13 drives the connecting rod 2 14 to slide. One end of the spring 2 15 is fixed on the outside of the connecting rod 2 14. The data cable 16 is protected from dust by the dustproof components.
[0034] The dustproof assembly includes two dust covers 17. The dust cover 17 is slidably connected to the outside of the data cable 16 and the outside of the connector 19. A cover plate 18 is rotatably connected to the outside of the dust cover 17. A rotating rod 20 is fixedly connected to the outside of the dust cover 17. The cover plate 18 is rotatably connected to the outside of the rotating rod 20. A torsion spring 21 is sleeved on the outside of the rotating rod 20. One end of the torsion spring 21 is fixedly connected to the outside of the dust cover 17, and the other end of the torsion spring 21 is fixedly connected to the outside of the cover plate 18. The dustproof assembly slides through the dust cover 17. The data cable 16 and the connector 19 are dustproofed by sliding inside the dust cover 17. The cover plate 18 is used to prevent dust from entering the interface of the connector 19. The rotating rod 20 serves as a pivot, and the cover plate 18 rotates around the rotating rod 20. The torsion spring 21 stores and releases energy through torsional deformation around the rotating rod 20. The dust cover 17 and the cover plate 18 are connected as one unit by the torsion spring 21.
[0035] The limiting block 7 is slidably connected inside the storage shaft 5 and inside the protective shell 6. The limiting block 7 is locked by sliding inside the storage shaft 5 and unlocked by sliding inside the protective shell 6.
[0036] One end of spring 9, away from the limiting block 7, is fixedly connected to the outside of the second protective shell 10, and the other end of spring 9 is fixed to the outside of the second protective shell 10 to constrain the direction of movement.
[0037] The connecting rod 8 is slidably connected inside the protective shell 10, and is fixedly connected to the outside of the trapezoidal block 11. The connecting rod 8 slides inside the protective shell 10 through the trapezoidal block 11.
[0038] The fixed block 13 is slidably connected inside the protective shell 12, the bottom of the spring 15 is fixedly connected to the top of the protective shell 10, and the connecting rod 14 is slidably connected to the outside of the trapezoidal block 11.

The spring 15 is fixed to the top of the protective shell 10 at the other end to constrain the direction of movement. The trapezoidal block 11 slides through the sliding of the connecting rod 14.
[0039] The support plate 2 is fixedly connected to the top of the housing 3, and the storage shaft 5 is rotatably connected inside the support plate 2. The support plate 2 is located at the top of the housing 3, which restricts the range of motion of the data cable 16. The storage shaft 5 is locked by sliding inside the support plate 2 and the limiting block 7.
[0040] One end of the coil spring 4 is fixedly connected to the outside of the housing 3. The coil spring 4 ensures the stable transmission of winding torque by being fixed to the outside of the housing 3.
[0041] Working principle:
[0042] When an HDMI cable is needed, press down on the fixing block 13. The fixing block 13 causes the connecting rod 14 to move down and compress the spring 15. After the vertical pressure is decomposed on the inclined surface of the trapezoidal block 11 and the thrust exceeds the maximum static friction, the trapezoidal block 11 slides along the inclined surface inside the protective shell 10, thereby causing the connecting rod 8 to slide and compress the spring 9. At the same time, the connecting rod 8 causes the limiting block 7 to disengage from the storage shaft 5, releasing the locking component. Pulling the data cable 16 outward will cause the storage shaft 5 connected to the coil spring 4 to rotate, so that the planar spiral coil spring 4 gradually unfolds from the axis outward and stores elastic potential energy. After the fixing block 13 is released, spring 2 15 pushes connecting rod 2 14 to reset the fixing block 13. Spring 1 9 rebounds and pushes connecting rod 1 8 to re-engage the limiting block 7 into the storage shaft 5, triggering the locking assembly to fix the storage shaft 5 and keep the data cable 16 in a stretched state. After use, the locking assembly is released, and the elastic restoring force of the coil spring 4 drives the storage shaft 5 to rotate in the opposite direction, evenly winding the data cable 16 back onto the storage shaft 5. During this process, the guide groove structure inside the housing 3 guides the cable to arrange in an orderly manner, avoiding tangling and knotting, and finally achieving automatic winding of the data cable 16.
[0043] When an HDMI cable is needed, pressing the cover 18 causes the torsion spring 21 to deform due to the torsional force. Since the torsion spring 21 tends to return to its initial state, a reverse torque is generated. As the cover 18 rotates, the torsion spring 21 continues to be torsion, allowing the connector 19 to be removed. When the cover 18 stops rotating, the torsion spring 21 releases its stored elastic potential energy, attempting to pull the cover 18 back to its original position. However, because the connector 19 is in use and abuts against the cover 18, the cover 18 remains in its current state. When the connector 19 is removed and no longer in use, the elastic potential energy released by the torsion spring 21 loses its resistance, driving the cover 18 to quickly return to its original position, precisely covering the connector 19's interface and effectively preventing dust and other impurities from entering the device, thus achieving a dustproof function. Furthermore, the tightly wound spring coil structure of the torsion spring 21 reduces frictional loss during operation, ensuring its long-term stable operation of the cover 18 and other dustproof components, continuously providing a reliable dustproof effect.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
