Problems solved by technology
As an electronic product, it usually has a Mini USB interface. After long-term use, it usually accumulates dust generated by static electricity, which will cause poor contact when connecting USB external devices.
[0003] In order to prevent the USB interface from accumulating dust, many electronic equipment manufacturers have introduced dust-proof measures, but the dust-proof measure is to install a dust cover or a dust cover at the USB interface, because the dust cover needs to be opened when using the USB interface. Or a dust cover, which is extremely inconvenient, and the dust-proof effect is not good

The invention discloses a USB interface of an electronic device, and an electronic device. The USB interface comprises a hollow housing and a circuit board, the circuit board is disposed in the hollow housing, the circuit board is also provided with a metal pin, the metal pin is parallel to a connecting finger on the circuit board, the metal pin is electrically connected with a power supply of the electronic device, the hollow housing is electrically connected with the power supply of the electronic device, the metal fin and the hollow housing form an electric field through the power supply, and micro dust around the metal pin moves to the inner wall of the hollow housing through the electric field. According to the invention, the micro dust around the metal pin is moved to the inner wall of the hollow housing through a charge effect, the micro dust can be conveniently removed, and an electrostatic dedusting function of the USB interface of the electronic device is realized.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of communication interfaces, and in particular, to a USB (Universal Serial Bus, Universal Serial Bus) interface of an electronic device and the electronic device. Background technique [0002] In the prior art, electronic equipment usually has a USB interface so that external electronic products can be electrically connected thereto. As an electronic product, it usually has a Mini USB interface. After long-term use, it usually accumulates dust generated by static electricity, which will cause poor contact when connecting USB external devices. [0003] In order to prevent the USB interface from accumulating dust, many electronic equipment manufacturers have introduced dust-proof measures, but the dust-proof measure is to install a dust cover or a dust cover at the USB interface, because the dust cover needs to be opened when using the USB interface. Or a dust cover, which is extremely i...
