Technical field

The present disclosure relates to the field of communication technology, and in particular to a plug structure.

Background technique

At present, the charging and data transmission functions of mobile terminals such as mobile phones can be realized by magnetic suction connection or traditional input/output (Input/Output, I/O) interface terminals. The magnetic connector includes a female socket at the device end and a male end suction head at the wire end. The attraction is generally provided by the magnets at the male and female ends. It is also possible to use a traditional I/O interface plug to be inserted into the female socket on the mobile phone to achieve physical contact. However, the physical characteristics of the magnet are that the lateral magnetic flux density is smaller than that of the positive and negative electrodes on the front, and the lateral magnetic attraction is smaller than the positive magnetic attraction. When the user is watching video or playing games while charging, the terminal device may need to be placed in a horizontal screen. , The wire will be pulled sideways when held by hand, which will easily cause the magnetic wire to fall off from the side and cause functional failure.

When the traditional I/O interface plug is placed on the horizontal screen of the terminal device, the wire will also be pulled, which is likely to cause damage to the wire.

Therefore, there is an urgent need for a plug structure to prevent the plug structure from being damaged by the pulling force of the wire caused by the hand holding the terminal device when using the terminal device while charging.

Summary of the invention

The embodiment of the present disclosure provides a plug structure to solve the problem in the related art that when the terminal device is used while charging, the plug structure is damaged by the pulling force of the wire caused by the hand holding the terminal device.

The embodiment of the present disclosure provides a plug structure, including:

A fixing part, the fixing part includes a plug;

A rotating part, the rotating part is rotatably connected with the fixed part, and the rotating part includes a wire, and the wire is electrically connected with the plug.

In this way, in the embodiments of the present disclosure, the rotation of the wire can be realized by the rotation of the rotating part and the fixing part of the plug structure, which not only facilitates the user to hold the terminal device, but also improves the service life of the plug structure.
