Description

Technical Field

[0001] The present application relates to the technical field of data line heat dissipation, and in particular to a data line that is easy to dissipate heat. Background Art

[0002] Data cables play an extremely important role in modern life and are widely used for data transmission and charging between various electronic devices. With the continuous development of science and technology, people's demand for data cables is not limited to transmission speed and stability, but also puts forward higher requirements for their durability and safety. The reliability and durability of data cables directly affect the normal use and life of electronic devices, and thus also affect the user experience.

[0003] Existing data cables are prone to heat up during data transmission and charging, leading to a series of problems. Factors such as overcurrent, long-term use, excessive charging current, poor cable contact, charger power mismatch, and poor data cable quality can all cause data cables to overheat. In order to solve the problem of data cable overheating, common technical methods mainly include improving the internal materials of the cable to increase its conductivity, reduce resistive heating, or using heat dissipation materials and heat dissipation structure designs on the outside. For example, some cables use high-conductivity metal materials inside to reduce resistance, and some designs use external heat sinks or heat dissipation holes for physical heat dissipation.

[0004] However, although these methods have alleviated the problem of data cable heating to a certain extent, in actual use, the heat generated inside the data cable cannot be effectively dissipated, especially in high-power usage environments, and a large amount of heat is still easily accumulated inside the cable, which not only affects the normal operation of the data cable, but may also accelerate the aging of the data cable and shorten its service life.

[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] The present application embodiment discloses a data line that is easy to dissipate heat. Figure 1 , including a wire body 1, a connector 2 and a shell 3. The middle part of the wire body 1 is telescopically connected to the inside of the shell 3, and the two ends of the wire body 1 are passed through the side walls of the shell 3. The connector 2 is fixedly connected to the two ends of the wire body 1. During use of the data cable, the wire body 1 is in a stretched state to increase the usable length. When the data cable is not in use, the wire body 1 is in a contracted state to accommodate the wire body 1, so as to improve the convenience of using the data cable.

[0038] Reference Figure 1 and Figure 2 The housing 3 includes a support frame 31 and two sealing plates 32. The two sealing plates 32 are respectively fixedly connected to two opposite frame surfaces of the support frame 31 to seal and protect the interior of the support frame 31. One wire body 1 is connected to two connectors 2, and the two connectors 2 are located at two opposite side walls of the support frame 31. At the same time, a telescopic component 8 for telescoping the wire body 1 is provided inside the support frame 31. When the data line is needed, the telescopic component 8 stretches the wire body 1 to increase the length for easy use. When the data line is not needed, the telescopic component 8 shrinks the wire body 1 to shorten the length for easy storage. It is worth mentioning that the board surface of the sealing plate 32 is provided with a snap-in groove 11 for the connector 2 to be inserted. When the data line is not needed, the connector 2 is inserted into the snap-in groove 11, so that the connector 2 is not easy to shake, which is conducive to improving the stability of the data line when it is stored.

[0039] Reference Figure 2 and Figure 3The telescopic assembly 8 includes a support rod 81, a movable column 82, a stopper 83 and a reset member 84. In this embodiment, the number of the support rods 81 is set to two. The two support rods 81 are fixedly connected to the inside of the support frame 31 and are arranged in parallel. The number of the movable columns 82 is also set to two. The two movable columns 82 are respectively movably sleeved on the two support rods 81. The line body 1 surrounds the two movable columns 82 in sequence. As the line body 1 is pulled, the two movable columns 82 move in a direction of approaching or moving away from each other. When the two movable columns 82 move in a direction of approaching each other, the line body 1 stretches to facilitate use. When the two movable columns 82 move in a direction of moving away from each other, the line body 1 shrinks to accommodate. The stopper 83 is set on the movable column 82. When the line body 1 is in a stretched state, the stopper 83 is used to limit the movable column 82 to improve the stability of the data line when it is used. When the line body 1 needs to shrink, the reset member 84 is used to release the limit operation of the stopper 83 to facilitate the accommodation of the data line.

[0040] Reference Figure 2 and Figure 3 The limiting member 83 includes a block 831 and a first spring 832. The inner side wall of the movable column 82 abuts against and slides on the support rod 81, and a receiving groove 9 for accommodating the block 831 and the first spring 832 is provided. One end of the first spring 832 is fixedly connected to the bottom of the receiving groove 9, and the other end of the first spring 832 is fixedly connected to the block 831. When the first spring 832 is in a natural state, the block 831 passes through the receiving groove 9. When the block 831 abuts against and slides on the side wall of the support rod 81, the first spring 832 is in a compressed state. At the same time, the support rod 81 is provided with a card hole 10 for inserting the card block 831. In this embodiment, the card hole 10 is provided in the middle position of the support rod 81. When the movable column 82 moves toward the direction approaching the locking hole 10, the wire body 1 is gradually stretched to be pulled out of the shell 3. When the movable column 82 moves to the position where the locking block 831 is opposite to the locking hole 10, the restoring force of the first spring 832 pushes the locking block 831 to be inserted into the locking hole 10. The locking block 831 is engaged with the locking hole 10 to fix the movable column 82 on the support rod 81, thereby maintaining the stability of the wire body 1 in the stretched state.

[0041] Reference Figure 2 and Figure 3The reset member 84 includes a second spring 841 and a pressing block 842. The second spring 841 is sleeved on the support rod 81. One end of the second spring 841 abuts against the inner wall of the support frame 31, and the other end of the second spring 841 abuts against the movable column 82. The pressing block 842 is movably arranged in the sealing plate 32, and the pressing block 842 is directly opposite to the clamping hole 10. When the clamping block 831 is inserted into the clamping hole 10, the line body 1 is in a stretched state, and the second spring 841 is in a compressed state. When the data line is not needed, the user presses the pressing block 842, and the pressing block 842 pushes the clamping block 831 out of the clamping hole 10. Then, the restoring force of the second spring 841 pushes the movable column 82 to reset, and the movable column 82 drives the line body 1 to perform a contraction operation. It should be noted that the pressing block 842 is connected with a spring. When the pressing block 842 pushes the clamping block 831 out of the clamping hole 10, the restoring force of the spring resets the pressing block 842, which is simple and convenient.

[0042] Reference Figure 4 and Figure 5 , a built-in air duct 4 is provided inside the wire body 1, and the built-in air duct 4 runs through the wire body 1 along the length direction of the wire body 1. At the same time, the connector 2 is provided with a vent 5, and the vent 5 is connected to the built-in air duct 4 to ventilate and dissipate heat for the data line in use. In order to improve the heat dissipation efficiency of the data line, the number of built-in air ducts 4 is set to at least two. In this embodiment, the number of built-in air ducts 4 is set to three, and the three built-in air ducts 4 are evenly spaced around the circumference of the material inside the wire body 1 to improve the uniformity of the heat dissipation operation. It should be noted that the material inside the wire body 1 is set to a metal material with good heat dissipation performance to further improve the heat dissipation performance of the data line. In addition, the connector 2 is provided with a reinforcement structure connected to the built-in air duct 4, and the design of the reinforcement structure is mainly used to improve the connection stability between the connector 2 and the built-in air duct 4. Typical reinforcement structures include but are not limited to protrusions, annular grooves, etc. These structures effectively increase the relative position stability between the connector 2 and the built-in air duct 4 by combining mechanical fixation and solder bonding. The reinforcement structure can take a variety of forms, such as spiral reinforcement ribs or grid-like reinforcement structures. The material of the reinforcement structure is also selected from metals with good heat dissipation performance, such as aluminum alloy or copper alloy. Such a design ensures that the connection between the vent 5 and the built-in air duct 4 will not loosen even in high-frequency vibration or application scenarios, thereby always maintaining a good heat dissipation effect.

[0043] Reference Figure 5, each joint 2 is provided with a plurality of vents 5, and the plurality of vents 5 are arranged crosswise on the joint 2. The vents 5 can be of different shapes and sizes according to design requirements, and typical choices include circular, triangular, trapezoidal, etc. The vents 5 are arranged crosswise and can be densely arranged on different sides or corners of the joint 2. This not only increases the surface area of ​​the joint 2 in contact with the air, but also ensures that the air entering from different directions can circulate through the built-in air duct 4.

[0044] Reference Figure 6 , the outside of the wire body 1 is set as a hollow structure. Specifically, the hollow structure includes heat dissipation holes 6 and connecting grooves 7 densely distributed on the outside of the wire body 1, and the two ends of the connecting groove 7 are respectively connected to two adjacent heat dissipation holes 6. The heat dissipation holes 6 can not only be circular, but also elliptical, square or irregular shapes. In order to increase the stability and aesthetics of the structure, the heat dissipation holes 6 can also be unevenly distributed, that is, the density of heat dissipation holes 6 is higher in some areas and lower in other areas. The material of the heat dissipation holes 6 can be made of polymer materials such as polypropylene and low-density polyethylene. Such a choice not only ensures a good insulation effect, but also improves its tensile strength. The connecting groove not only helps to further enhance the heat dissipation performance, but also reduces the adhesion between the wire bodies 1, avoiding twisting and entanglement during use.

[0045] The implementation principle of a data cable that is easy to dissipate heat in the embodiment of the present application is as follows: by setting a built-in air duct 4 inside the wire body 1 of the data cable, and coordinating the optimized design of the hollow structure and materials, the heat dissipation performance of the data cable is significantly improved. The design of the built-in air duct 4 not only increases the air circulation inside the data cable, but also improves the utilization rate of the thermal conductive material. The introduction of the hollow structure greatly increases the heat dissipation area on the surface of the wire body 1, which is more conducive to the dissipation of heat, and can effectively solve the problem of internal heat accumulation of the existing data cable under high-power use environment, and significantly improves the reliability and service life of the data cable. The cross-arranged vents 5 not only enhance the air circulation effect, but also ensure all-round heat dissipation through the design of different angles. The introduction of the reinforcement structure improves the connection stability between the connector 2 and the built-in air duct 4, so that the entire data cable can maintain efficient heat dissipation even in frequent use or vibration environment. The combination of these improvement measures has significantly improved the reliability of the data cable under complex use conditions and further extended its service life.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
