Description

Technical Field

[0001] This utility model relates to the field of automotive USB data cable technology, and in particular to a USB data cable for automobiles. Background Technology

[0002] A car USB data cable is a data transmission cable used for a car's USB port. Its function is to connect USB devices to the car's USB port to enable data transmission and charging. Car USB data cables can be used for data transmission and charging of various in-vehicle devices, and can also connect smartphones, tablets, and other devices to the car's audio or entertainment system via the car's USB port.

[0003] A prior art USB data cable for automobiles, disclosed in patent CN221102651U, includes a cable retractor with a cable wound and coiled inside. One end of the cable has a USB plug, and the other end has a connector for connecting three connecting wires. Each connecting wire has a different interface type to meet the transmission needs of different devices. The connector has slots on its side that are compatible with each interface for protection. This design solves the problem of unused interfaces being scattered during data cable use, making them susceptible to damage from impacts or water ingress, thus affecting usability.

[0004] The aforementioned existing technology has certain drawbacks; if any of the three connecting cables is damaged and needs to be replaced, the entire data cable needs to be replaced, increasing the user's financial expenditure; furthermore, some users prefer data cables with different colors or data cable plugs featuring cartoon characters, requiring them to purchase the necessary data cables, further increasing their financial expenditure; if a detachable data cable were provided, the user would only need to replace the required data cable portion, while the cable reel box remains unchanged, reducing the user's financial expenditure and expanding the market; therefore, this application proposes a USB data cable for automobiles.

[0008] Three data connection cables;

[0009] A connection mechanism is provided; the connection mechanism is capable of detaching and connecting three data connection cables to an extension data cable; the connection mechanism includes a female connector connected to the extension data cable, the female connector having a USB slot connected to the extension data cable, male connectors fixed on the three data connection cables, a connection block fixed on the male connectors, and a USB plug installed on the connection block that connects to the three data connection cables and mates with the USB slot; the USB plug, when inserted into the USB slot, locks the connection block and the female connector together.

[0010] Preferably, the female connector has a connection groove, and the USB slot is disposed in the connection groove.

[0011] Preferably, the inner wall of the connecting groove is fixed with two limiting protrusions, and the outer wall of the connecting block is provided with two strip grooves. When the USB plug is inserted into the USB slot, the limiting protrusions are located in the strip grooves.

[0012] Preferably, the connecting female head is provided with two sets of deformation grooves, the deformation grooves including two through grooves that penetrate the connecting female head and communicate with the connecting groove, the through grooves being located on both sides of the limiting protrusion.

[0013] Preferably, the limiting protrusion is arc-shaped and is integrally formed with the connecting female head.

[0014] Preferably, the connecting block slides against the inner wall of the connecting groove.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] In summary, this utility model allows for the opposite-direction pulling of the male and female connectors, causing the limiting protrusion to disengage from the strip groove. This enables the replacement of the required male connector and the corresponding data cable color, etc. The disassembly and assembly operations are simple and convenient. It can be separated from the cable take-up box and the data cable can be disassembled, reducing the cost of replacement. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 3 A USB data cable for automobiles includes a cable retractor 1, which houses an extension data cable 2. The cable retractor 1 is also connected to a connecting cable with a plug attached to it, which is not shown in the figure.

[0023] Three data connection cables 3, each with a different data plug connected to its end, are shown in the figure.

[0024] All of the above are existing technologies.

[0025] The connection mechanism is capable of detaching and connecting the three data connection cables 3 to the extension data cable 2. The connection mechanism includes a female connector 4 connected to the extension data cable 2. The female connector 4 is provided with a USB slot 7 connected to the extension data cable 2. The female connector 4 is provided with a connection groove 6, and the USB slot 7 is disposed in the connection groove 6.

[0026] Three data connection lines 3 are fixed with male connectors 5, and male connectors 5 are fixed with connecting blocks 11. Connecting blocks 11 slide against the inner wall of connecting grooves 6. The end of connecting blocks 11 can be chamfered so that it can cooperate with the arc-shaped limiting protrusions 9 to reduce resistance during movement.

[0027] The connecting block 11 is equipped with a USB plug 10 that connects to three data connection cables 3 and mates with a USB slot 7. When the USB plug 10 is inserted into the USB slot 7, it can lock the connecting block 11 and the connecting female head 4 together. The inner wall of the connecting groove 6 is fixed with two limiting protrusions 9. The limiting protrusions 9 are arc-shaped and are integrally formed with the connecting female head 4. The outer wall of the connecting block 11 is provided with two strip grooves 12.

[0028] To facilitate the connection between the male connector 5 and the female connector 4, the female connector 4 is provided with two sets of deformation grooves. The deformation grooves include two through grooves 8 that pass through the female connector 4 and communicate with the connecting groove 6. The through grooves 8 are located on both sides of the limiting protrusion 9. In this way, the female connector 4 can be divided into parts, giving it a certain deformation capability.

[0029] When the USB plug 10 is inserted into the USB slot 7, the connecting block 11 slides against the inner wall of the connecting groove 6. As the connecting block 11 moves, it abuts against the limiting protrusion 9. Under the pressure of the connecting block 11, the limiting protrusion 9 and the divided connecting female head 4 open outward, which makes it easy to install the connecting block 11 in the connecting groove 6. When the USB plug 10 is inserted into the USB slot 7, the limiting protrusion 9 is located in the strip groove 12, which can connect the connecting male head 5 and the connecting female head 4 together, ensuring the stability of the connection between the two.

[0030] Pull the male connector 5 and the female connector 4 in opposite directions to disengage the limiting protrusion 9 from the strip groove 12. This allows you to change the required male connector 5 and the corresponding data cable 3 color, making the disassembly and assembly operation simple and convenient.

[0031] As mentioned above, even if the data cable 3 is damaged, it can be separated from the cable box 1, and the data cable 3 can be disassembled, reducing the cost of replacement.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
