Description
Technical field
The invention is related to Cellphone Accessories technical field, dust-proof more particularly, to a kind of novel mobile phone mainboard USB jack
Device.
Background technology
Mobile phone increasingly gos deep into the life of people, but the USB jack of mobile phone is not often to need to use, when mobile phone
When USB jack is in idle state, often has substantial amounts of dust and take advantage of the occasion and enter, influence the property of the internal electron part of mobile phone
Can, internal electron part is even damaged when serious, so as to shorten the service life of mobile phone.
The content of the invention
The main purpose of the invention is to provide a kind of dust-proof dress of novel mobile phone mainboard USB jack regarding to the issue above
Put.
In order to solve the above technical problems, the technical solution that the invention uses is：A kind of novel mobile phone mainboard USB jack
Dust guard, including mainboard and the USB jack on mainboard, the mainboard by the USB jack are equipped with dustproof cover and shaft,
The dustproof cover is fixedly connected with shaft, and the top of the shaft, which is equipped with, drives the rotating knob of shaft, knob band turn
Axis is until final drive dustproof cover rotation and cover USB jack or open USB jack.
Further, the height of the shaft is 1-2mm, and mobile phone shell is stuck in dustproof cover and knob when phone housing encapsulates mainboard
Between shaft around.
Further, the knob is connected with shaft with snap fit, first can be plucked knob when phone housing encapsulates mainboard
Knob is connected to shaft upper end again after the completion of lower encapsulation.
The invention has the advantages and positive effects of：So that the USB jack of cell phone mainboard is covered when idle
Internal electron part is damaged so as to effectively avoid dust from being entered by USB jack, it is simple and practical in structure, it is cost-effective.
Brief description of the drawings
Fig. 1 is the signal of the part-structure equipped with USB jack one end of the novel mobile phone mainboard USB jack dust guard
Figure.
In figure：1- mainboards, 2-USB sockets, 3- dustproof covers, 4- shafts, 5- knobs.
Embodiment
In order to be better understood from the invention, with reference to specific embodiments and the drawings to the invention into advance one
The description of step.
As shown in the figure, the invention provides a kind of novel mobile phone mainboard USB jack dust guard, including mainboard 1 and set
In the USB jack 2 on mainboard 1, the mainboard 1 on the side of USB jack 2 is equipped with dustproof cover 3 and shaft 4, the dustproof cover 3 and turn
Axis 4 is fixedly connected, and the top of the shaft 4, which is equipped with, drives the rotating knob 5 of shaft 4.
Further, the height of the shaft 4 is 1-2mm.
Further, the knob 5 is connected with shaft 4 with snap fit.
The invention drives the rotation of shaft 4 to be further driven to dustproof cover 3 and rotates when in use, by turn knob 5,
If when need to connect USB data line then rotatable knob 5 so that dustproof cover 3 leaves the upper end of USB jack 2, if USB jack is left unused
When then rotatable knob 5 so that dustproof cover 3 covers USB jack 2 so as to preventing dust from entering.The invention causes cell phone mainboard
USB jack it is covered when idle damage internal electron part so as to effectively avoid dust from being entered by USB jack, structure letter
It is single practical, it is easy to operate, it is cost-effective.
The embodiment of the invention is described in detail above, but the content is only the preferable of the invention
Embodiment, it is impossible to be construed as limiting the practical range of the invention.All impartial changes made according to the invention scope
Change and improvement etc., should all still belong within this patent covering scope.
