Description

Technical Field

[0001] The utility model relates to the technical field of USB data lines, in particular to a breakage-resistant USB data connection line. Background Art

[0002] A USB cable is a cable that connects an electronic device to an external device such as a computer. It usually consists of a USB port and a connector on the other end. Its function is to transmit data and power signals, allowing the device to charge or transfer data with other devices. USB cables come in different types and materials. Some are able to support high-speed data transfer, while others are designed to be rugged and durable. Common uses include connecting mobile phones, tablets, cameras, MP3s, and other devices.

[0003] When some existing USB data cables are in use, a protective device is fixedly connected to the end of the wiring harness. However, the protective device cannot be disassembled and replaced after being damaged, and the damaged protective frame cannot continue to maintain the original protective function.

[0004] For example, a USB-to-serial port connection cable disclosed in announcement number CN210490017U can effectively protect the serial port connector by setting a protective box at the serial port end and utilizing multiple magnets to attract each other and a rubber partition, thereby extending the service life of the serial port connector. Compared with the traditional exposed serial port connector, it is more protective and can avoid damage to the serial port connector and the economic loss caused by long-term replacement of the serial port connector. By setting a protective frame and utilizing the softness of the transmission line itself, the transmission line connector can be prevented from loosening or even breaking, which can also extend the service life of the entire USB-to-serial port connection cable and is more practical.

[0005] However, the protective frame of the patent is fixedly connected to the joint protective cover, and the protective frame cannot be disassembled and replaced after being damaged, and the damaged protective frame cannot continue to maintain the original protective function.

[0006] Therefore, it is necessary to invent a break-proof USB data connection line to solve the above problems. Utility Model Content

[0011] The rubber protective mechanism has an insulating effect on the one hand, and is not easy to wear against the wiring harness body on the other hand.

[0012] Preferably, the number of the No. 1 support bar and the No. 2 support bar are both set to four, and the four No. 1 support bars and the four No. 2 support bars are evenly distributed around both ends of the wiring harness body.

[0013] The bending stress at the connection of the wire harness end is relieved by the bending deformation of the No. 1 support bar and the No. 2 support bar.

[0014] Preferably, both ends of the wiring harness body close to the input end and the output end are sleeved with protective covers, and the shape of the protective covers is set to be spiral.
