A travel switch is installed on the inner wall of the card slot. One end of the travel switch is connected to a buzzer, and the buzzer is installed on the USB data cable. In the plug, the power input end of the buzzer is connected to a button battery, the metal contact at one end of the button battery is set opposite to the metal contact of the buzzer, and a spacer is movable between the two metal contacts.

As a preferred technical solution, the spacer is placed in a slot, the slot is located on the upper surface of the USB data line plug, and the lower end of the slot is facing the middle contact end of the button battery and the metal contact piece of the buzzer.

As a preferred technical solution, both the buzzer and the button battery are installed in a cavity inside the USB data line plug, and the cavity is located at the lower end of the slot.

As a preferred technical solution, a detachable cover plate is provided outside the cavity, and the cavity is sealed through the cover plate, and the slot is opened on the top surface of the cover plate.

The beneficial effects of the utility model are: the utility model utilizes the function of the push plate on one side. After the metal connector is inserted into the socket, the whole push plate presses the travel switch. At this time, the travel switch is closed and the buzzer is closed. After the metal connector is pulled out, the travel switch is triggered, and the buzzer is turned on at this time, telling the user to pull out the plug, which effectively acts as an anti-theft reminder, and the function of the push plate can play a buffering role. When in use, it can effectively protect the USB connector from being bent and deformed when it is hit.
