Description

Technical Field

[0001] The utility model relates to the technical field of data connection lines, in particular to a connection line with an extension function. Background Art

[0002] In the early computing era, the demand for data transmission was relatively simple, and the technology of connection lines was also relatively primitive. With the rapid development of computer technology, the growth of data volume and the requirement for transmission speed have been continuously increasing. The progress of communication technology has provided strong support for the development of data connection lines. From the initial serial communication to parallel communication, and then to the emergence of high-speed serial bus technologies such as USB (Universal Serial Bus) and Thunderbolt (Thunderbolt interface), etc., the data transmission rate and efficiency have been greatly improved. The development of materials science enables connection lines to adopt higher-quality conductor materials such as copper and silver, as well as better insulating materials, reducing signal attenuation and interference. The breakthrough of integrated circuit technology enables the control chips of connection line interfaces to achieve more complex functions such as error correction, encryption, and power management. At the same time, the rapid growth of the consumer electronics market and diverse application requirements such as high-definition video transmission, large-capacity data storage, and fast charging have promoted the continuous innovation and improvement of data connection lines to meet the requirements of different devices and scenarios.

[0003] A data connection line usually consists of the following main components: Conductors: They are the core part of data transmission, generally made of good conductive materials such as copper. The design of multi-strand conductors can increase flexibility and durability. Insulation layer: Wrapped outside the conductors, usually made of plastic, rubber, or other insulating materials. It plays a role in isolating the conductors, preventing short circuits, and reducing signal interference. Connectors: Located at both ends of the connection line, used to connect with the interfaces of devices. Shielding layer (some data lines have): Composed of metal braided mesh or foil. It is used to reduce the influence of external electromagnetic interference on data transmission and improve the stability of signals. Plug housing: Protects the components inside the connector and provides mechanical strength. The material is usually plastic or metal. Fixing parts: Used to fix the conductors and connectors to prevent the internal circuits from being disconnected when pulled.

[0004] Existing data connection lines generally lack the functions of storage and extension, resulting in the wires being randomly placed on the desktop, looking extremely messy, and seriously affecting the beauty of the desktop. In addition, existing extended data lines usually achieve the extension operation by pulling the wire head. This method is very likely to damage the data line, shorten its service life, and increase the risk of the data line malfunctioning. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a connecting line with an extension function, including a data line 1. A top plate 3 is fixedly connected to the front part of the outer side of the data line 1. An air pipe 17 is fixedly connected to the top of the front end of the top plate 3. A ventilation frame 18 is fixedly connected to the rear part of the inner side of the air pipe 17. Air holes are equidistantly arranged on the outer side of the front end of the ventilation frame 18. A sliding rod 19 is slidably connected to the middle part of the front end of the ventilation frame 18. A piston 20 is fixedly connected to the middle part of the rear end of the sliding rod 19. A pressing head 21 is fixedly connected to the middle part of the front end of the sliding rod 19. A return spring 22 is sleeved on the front part of the outer side of the sliding rod 19. After use, the user only needs to press the pressing head 21 on the sliding rod 19. At this time, the first spring 5 on the rubber tube sleeve 4 returns to its original state under the elastic action, causing the excess air in the rubber tube sleeve 4 to be discharged through the air holes on the ventilation frame 18 in the air pipe 17, so that the data line 1 is recycled.

[0030] Refer to Figures 1 - 2 , a rubber tube sleeve 4 is fixedly connected to the rear end of the top plate 3. First springs 5 are fixedly connected to both the inner side and the outer side of the rubber tube sleeve 4. A barrier sleeve 2 is arranged on the inner side of the rubber tube sleeve 4. A data plug 8 is fixedly connected to the middle part of the front end of the data line 1. A data connector 7 is fixedly connected to the middle part of the rear end of the data line 1. Magnetic positioning rings are equidistantly fixedly connected to the outer side of the data line 1. A bottom plate 9 is fixedly connected to the rear part of the outer side of the data line 1. The user extends the data line 1 by pulling the anti-slip rope 16 and the dust cover 13 at the rear end. When the data line 1 is extended, the rubber tube sleeve 4 inside the data connecting line expands under the extension support of the first spring 5. At this time, the sliding rod 19 in the air pipe 17 is opened by the piston 20 on the air pipe 17 under the negative pressure in the rubber tube sleeve 4, so that the air pressure inside and outside the rubber tube sleeve 4 is balanced, maintaining the extension effect of the data connecting line.

[0031] Refer to Figures 1 - 3 , magnetic blocks 11 are fixedly connected to both the upper and lower sides of the rear end of the bottom plate 9. Magnetic blocks 11 are fixedly connected to both the left and right sides of the front end of the top plate 3. An elastic connecting rope 10 is fixedly connected to the bottom of the front end of the top plate 3. The other end of the elastic connecting rope 10 is fixedly connected to a dust cover 13. Magnets 12 are fixedly connected to both the left and right sides of the rear end of the front dust cover 13. A protective housing 6 is fixedly connected to the outer side of the top plate 3. A hanging rope ring 14 is fixedly connected to the top end of the outer side of the protective housing 6. An anti-slip rope 16 is sleeved on the middle part of the outer side of the hanging rope ring 14. A rope buckle 15 is fixedly connected to the middle and lower part of the outer side of the anti-slip rope 16. When the user uses the data connecting line, the dust covers 13 at both ends of the data connecting line are opened, so that the data connector 7 and the data plug 8 on the data line 1 are exposed, facilitating the user's use. The magnetic positioning rings on the data line 1 can ensure that the data line 1 is kept neat when recycled, preventing knotting and entanglement, which affects the next use. Then the dust cover 13 is covered, so that the magnetic block 11 is adsorbed on the magnet 12 to prevent loosening.

[0032] Working principle: When the user uses the data connection cable, open the dust covers 13 at both ends of the data connection cable, so that the data connectors 7 and data plugs 8 on the data cable 1 are exposed for the user's convenience. Subsequently, the user extends the data cable 1 by pulling the anti-slip rope 16 and the dust cover 13 at the rear end. When the data cable 1 extends, the rubber tube sleeve 4 inside the data connection cable expands under the extension support of the first spring 5. The extension component is composed of the rubber tube sleeve 4 and the first spring 5. The rubber tube sleeve 4 (made of flexible plastic) fixes the first spring 5 on the outside of the rubber tube sleeve 4, ensuring the sealing inside the tube during extension. At the same time, when the data cable is retracted, it can ensure the spring buffer during spring recovery. At this time, the sliding rod 19 in the air tube 17 is under the negative pressure in the rubber tube sleeve 4, opening the piston 20 on the air tube 17, so that the air pressure inside and outside the rubber tube sleeve 4 is balanced, maintaining the extension effect of the data connection cable. When the use is completed, the user only needs to press the pressing head 21 on the sliding rod 19. At this time, the first spring 5 on the rubber tube sleeve 4 returns to its original state under the elastic action, causing the excess air in the rubber tube sleeve 4 to be discharged through the pores on the ventilation rack 18 in the air tube 17, so that the data cable 1 is retracted. The magnetic positioning ring on the data cable 1 can ensure that the data cable 1 is neatly retracted when it is retracted, preventing it from knotting and tangling together, which affects the next use. Then cover the dust cover 13 so that the magnetic block 11 is adsorbed on the magnet 12 to prevent loosening.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
