Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3, the anti-crack USB cable provided in this embodiment includes a connecting cable body 10 and USB connectors 20 disposed at two ends of the connecting cable body 10, the connecting line body 10 and the USB connector 20 are connected by a terminal sheath 30, the terminal sheath 30 is disposed outside the connecting wire body 10 and the terminal sheath 30 is fixedly connected to the USB connector 20, so as to protect the connection position of the connecting wire body 10 and the USB connector 20, specifically, the tip protector 30 includes a connecting portion 31 integrally formed with the USB connector 20, the top surface and the bottom surface of the connecting part 31 are both provided with a positioning groove 311, the positioning groove 311 is circular, the positioning groove 311 is convenient for fingers to position when the connecting part 31 is held, so that the connecting part can be plugged and pulled out, and the service life of the anti-crack USB cable is prolonged. Connecting portion 31 is kept away from the one end of USB joint 20 still is equipped with protection axle sleeve 32, connecting wire body 10 is followed pass in the connecting axle sleeve and with be equipped with certain clearance between the protection axle sleeve 32, the one end of protection axle sleeve 32 with connecting portion 31 integrated into one piece, just be equipped with a plurality of arriss form arch 321 on the protection axle sleeve 32, arris form arch 321 is followed the length direction of connecting wire body 10 sets up, the inside of arris form arch 321 is equipped with elastic metal wire 322 in order to further improve this protection axle sleeve 32's anti effect of buckling, does benefit to and protects this inside connecting wire body 10 of protection axle sleeve 32.

In this embodiment, since the connecting wire body 10 is often folded when not in use, the connecting wire body 10 is easily broken, and in order to protect the connecting wire body 10, at least one reinforcing sheath 40 is further slidably mounted on the connecting wire body 10, the reinforcing sheath 40 includes an upper shell 42 and a lower shell 41, the upper shell 42 and the lower shell 41 can be mutually fastened, a wire hole through which the connecting wire body 10 can pass is formed between the upper shell 42 and the lower shell 41, specifically, the lower shell 41 and the upper shell 42 are respectively provided with a lower pressing piece 411 and an upper pressing piece at two ends of the wire hole, the top of the lower pressing piece 411 and the bottom of the upper pressing piece are respectively provided with a plurality of pressing strips 412, and the pressing strips 412 are arranged perpendicular to the length direction of the connecting wire body 10.
