[0002] The connection end of the USB cable in the prior art is installed in the product, and the other end is a USB end for connecting with another product. When the wire is pulled vertically through the USB end, the core wire in the wire will be produced along with the wire. In the case of displacement and shrinkage, when it is used for a long time, it will cause poor contact at the connection end

The invention provides a USB connection wire capable of preventing core wire displacement. The USB connection wire comprises a USB end, a wire rod and a connecting end; the USB end is connected with the connecting end through a core wire wrapped by the wire rod; the connecting end comprises a terminal, a wire core, an SR outer mold and a PP inner mold, wherein the wire core extends out of the wirerod and then is connected with the terminal; the right end of the core wire is connected with the wire rod through the PP inner mold; and the SR outer mold is disposed at the joint of the PP inner mold and the wire rod. According to the USB connection wire of the invention, the PP inner mold connected with the wire rod is arranged at the right end of the core wire; and the outer surface of the joint of the PP inner mold and the wire rod is provided with the SR outer mold; and the terminal, the core wire, the PP inner mold and the SR outer mold are fixed on a mechanical device through a plastic sheath which is formed by means of injection molding. When the USB end of the wire rod is pulled, the core wire in the wire rod moves to the force bearing end, and however, according to the USB connection wire of the invention, the core wire is fixed through the hard PP inner mold formed by means of injection molding, and therefore, the core wire can play a role of a weight, and the core wire connected with the terminal can be prevented from being displaced.
Description
technical field [0001] The invention relates to the field of USB connecting wires, in particular to a USB connecting wire which prevents displacement of core wires. Background technique [0002] The connection end of the USB cable in the prior art is installed in the product, and the other end is a USB end for connecting with another product. When the wire is pulled vertically through the USB end, the core wire in the wire will be produced along with the wire. In the case of displacement and shrinkage, when it is used for a long time, it will cause poor contact at the connecting end. Contents of the invention [0003] The object of the present invention is to provide a USB connection cable which prevents displacement of the core wire. [0004] In order to achieve the above object, the present invention improves the following technical solutions: [0005] A USB connection cable for preventing displacement of the core wire, comprising a USB end, a wire rod and a connection...
