The electronic device usually further includes an antenna for information interaction, and a housing of the current USB socket is a metal member, which is prone to collect static electricity, thereby causing adverse effects on normal operation of the antenna. Meanwhile, a positioning hole is formed in the side wall of the shell of the current USB socket, the positioning hole can be in positioning fit with the anti-falling elastic hook on the USB plug in the inserting direction of the positioning hole, the positioning hole is directly communicated with the inside of the electronic equipment, and the electronic equipment is easy to feed liquid and is damaged.

In addition, whether the design of the USB socket is reasonable or not greatly affects the size of the electronic device today when the electronic device is miniaturized more and more. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a USB plug and a USB socket in the prior art. In fig. 1, a tongue 11 of a USB socket 10 is assembled in a housing 12 of the USB socket 10, a patch pin 13 is disposed on the tongue 11, and the patch pin 13 transmits data through a USB plug 20 attached to the tongue 11. In the process of manufacturing the USB socket 10 shown in fig. 1, a manufacturer usually assembles the finished tongue 11 into the shell 12, and a process gap 14 exists between the tongue 11 and the shell 12, so that the tongue 11 is in a loose state. When the USB plug 20 is inserted, it will directly abut on the tongue 11, and will cause the tongue 11 to move, and the movement of the tongue 11 will cause the patch pin 13 to be pushed. After long-term operation, fatigue cracks and even fractures can occur due to frequent movements of the patch foot 13.
