The existing USB plug receptacle as data transmission interface, is not provided with protective equipment under normal circumstances and protects to it on table,
Either a set of protective equipment is shared with other plug receptacles.
When USB plug receptacle is not provided with protective equipment, it is at unshielded state；And when USB plug receptacle connects with other
When socket or button share a set of protective equipment, if other plug receptacles are chronically at use state, protective equipment is not just had
Protective action, USB plug receptacle are also corresponded at this time in unshielded state.When USB plug receptacle is in unshielded state, USB is connect
Socket is easy the erosion by dust and steam etc., will cause the poor contact of USB plug receptacle or causes data transmission fault；And
Shared protective equipment is in the case where being extruded or vibrating, it is easy in the state opened or fallen off, will also result in anti-
The failure of protective function.
Summary of the invention
It is an object of the present invention to provide a kind of USB interfaces with safeguard function, to provide USB plug receptacle independent anti-
Shield, can make USB plug receptacle obtain the protection of higher level.
To achieve the goals above, invention uses a kind of technical solution below: USB interface with safeguard function,
The protection cavity being arranged on instrument and meter including USB plug receptacle and one and the protective cover for protecting cavity to cooperate, USB plug receptacle position
In protection cavity bottom；The connecting pin two sides of the protective cover and protection cavity are equipped with rotary shaft, and protection cavity inner wall top is set
There is sliding rail matching with rotary shaft, for rotary shaft rotation and horizontal sliding, the sliding rail includes inner segment sliding rail and outer segment
Sliding rail, inner segment sliding rail are the cylindrical hole matched with rotary shaft, and inner segment sliding rail and outer segment sliding rail junction are equipped with detent salient point, card
Track width at the salient point of position is slightly less than the diameter of rotary shaft, the width of outer segment sliding rail since at detent salient point gradually increase outward
Greatly, the track width of outer segment sliding rail outermost end is not less than the diameter of rotary shaft；The opening end of the protective cover is located at instrument and meter
Sidewall edge.
Further, the lower surface two sides of the connecting pin of the protective cover and protection cavity are equipped with upper supporting block, described anti-
Shield cavity two sides inner wall is equipped with the lower supporting block matched with upper supporting block, and the lower end surface of the upper supporting block is lower than rotary shaft
Minimum point, the upper surface of lower supporting block is lower than the lowest part of sliding rail.
Further, the opening end two sides of the protective cover are respectively provided with a buckle, and the protection cavity is opened with protective cover
The corresponding two sidewalls Qi Duan are equipped with the card slot for the horizontal push-in of buckle.
Further, the lower surface of the protective cover opening end is equipped with recess of uncapping.
Further, the upper surface of the protective cover is equipped with several anti-skidding steps for increasing frictional force.
Beneficial effects of the present invention: independent protection is carried out to USB plug receptacle using protective cover, instrument and meter can be improved
Degree of protection can make the degree of protection of instrument and meter reach IP54.Protective cover can prevent dust and steam etc. from entering or stopping
In USB plug receptacle, USB plug receptacle plug in trouble or damage instrument and meter are prevented.Using the design of detent salient point, protecting
After lid slides into, detent salient point can prevent rotary shaft from sliding on the slide rail, so that protective cover skids off；It is set using buckle and card slot
Meter, after protective cover slides into, under the action of buckle and card slot, protective cover can be fitted securely on protection cavity, so that
Protective cover must be opened artificially actively opening Shi Caineng, and otherwise protective cover will be in permanent guard mode.
