Detailed Description

The invention aims to improve the conventional USB flash disk bracelet so as to improve the reliability of the electrical connection of the USB flash disk bracelet. The idea is to configure the switch module to electrically disconnect at least a portion of the data line connected to the second USB connector from the first USB connector when the USB connector (for convenience of description, the USB connector is otherwise referred to as the first USB connector) of the USB disk body is connected to the device.

The invention is further illustrated with reference to the following figures and examples.

The first embodiment:

as shown in fig. 1, the U-disk bracelet includes a U-disk body 4, the U-disk body 4 has a first USB connector 42 and a U-disk module 41, the U-disk bracelet further includes a second USB connector 1 connected to the first USB connector 42 via a data line 2, a switch module 3 is disposed on the U-disk body 4, and the switch module 3 is connected in series between the first USB connector 42 and the data line 2.

The two using methods are as follows: the first USB connector 1 and the second USB connector 1 are connected with the equipment, in the using state, the switch module 3 is closed, and the USB flash disk module 41 is connected with the equipment for use through the data line 2 and the second USB connector 1. Second, the first USB connector 42 is connected to the device, in the use state, the switch module 3 is disconnected, so that at least a portion of the data line 2 is electrically disconnected from the first USB connector 42, the USB module 41 is connected to the device through the first USB connector 42, and since at least a portion of the data line 2 is electrically disconnected from the first USB connector 42, the current is prevented from flowing to the data line 2, thereby improving the signal strength and the reliability of the electrical connection between the USB module 41 and the device.

The switch module 3 may be a manual switch. A quad switch may be used to switch the USB voltage, ground, D +, D-on or off, respectively.
