Description
Technical field
The utility model relates to technical field of electronic products.More particularly, the utility model relates to a kind of USB interface.
Background technology
The USB interface of general electronic products is all outside exposed, but after a long time use, easily accumulates dust or enter foreign matter, the contact of USB loose contact or the inside can be caused like this to be scraped off.
For solving the problem; current electronic product is on the market in order to dust-proof and anti-foreign matter; the lid of a rubber or plastic cement is all increased at USB interface place; during use, lid is opened; USB joint is inserted USB interface; after finishing using; directly USB interface is covered with lid; thus protect USB interface, but add the increase that lid means product cost, and add the complexity that user uses USB interface; if forget cover lid after using; or lid is not built, be easy to into foreign matter and dust, very large on the impact of electronic product.
In view of above description, one is urgently had can effectively to prevent dust and foreign matter from entering in USB interface, and the damage of contact in the USB interface that user can be avoided to cause because of improper use, reduce the complexity of user operation and the complexity of structure, the generation of the USB interface of product cost can be reduced simultaneously.
Utility model content
The purpose of this utility model overcomes prior art defect, one is provided can effectively to prevent dust and foreign matter from entering in USB interface, and the damage of contact in the USB interface that user can be avoided to cause because of improper use, reduce the complexity of user operation and the complexity of structure, the USB interface of product cost can be reduced simultaneously.
For solving the problem, the utility model discloses a kind of USB interface, it is characterized in that, comprising:
Housing, it has blind end and openend, is provided with contact in described housing;
At least two elastic partss, its one end is separately fixed at the blind end of described housing;
Baffle plate, it is connected with the other end of arbitrary described elastic parts, and described baffle plate is arranged in described housing cavity, and described baffle plate is provided with the through hole passed through for described contact.Described at least two elastic partss are for connecting the blind end of described housing and described baffle plate, at least two elastic partss are such as by the blind end that is weldingly fixed on described housing and described baffle plate, such as ensureing elastic parts uniform force, described at least two elastic partss can be 2, its one end is fixed on the blind end of described housing, and the other end is installed in the both sides of described through hole respectively.User in use, USB joint is only needed directly to insert in USB interface, under the effect of artificial applying active force, described baffle plate shifts to described housings close end from described shell nozzle end along its sidewall, described contact is through the through hole on described baffle plate, and under the impetus of described baffle plate, described two elastic partss such as spring can compress, thus USB joint is contacted with the Metal Contact sheet on described contact, realize transfer of data.After finishing using; USB joint is extracted by user from described USB interface; described two elastic partss can restore to the original state under the effect not having external force; therefore promote described baffle plate and shift to openend from the blind end of described housing; now described contact can pass described through hole; under the restoring force effect of described elastic parts such as spring; described baffle plate is pushed to the openend of described housing and shelters from the openend of described housing; thus make described baffle plate play protection to described contact, prevent dust and foreign matter to enter in described USB interface simultaneously.The utility model by fixing elastic parts in the inner chamber of described USB interface, and connect the blind end of described USB interface and described baffle plate with described elastic parts, described elastic parts such as spring by compression and restorable process in, described baffle plate is in the blind end of described housing and openend motion, thus realize operationally out contacting exposed for described Metal Contact sheet with USB joint and the openend of described USB interface can being blocked when inoperative, therefore effectively can prevent dust and foreign matter from entering in USB interface, reduce the turnover rate of USB interface.Because design lid that need not be extra just can play preventing dust foreign matter and protect the effect of contact; thus reduce the complexity of electronic product structure; decrease the complexity using and reduce the production mould of housing of material simultaneously, reduce the cost of product.Avoid the interface damage because user's improper use causes simultaneously, reduce the complexity of user operation, improve the serviceability of terminal use.Structure of the present utility model is applicable to mecro USB interface, standard USB and mini USB interface.
Wherein in an embodiment, in described USB interface, the blind end of described housing is provided with the first groove for holding described elastic parts.One end of described elastic parts is fixed in the groove of described housings close end, and described groove is for holding described elastic parts.
