Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of dustproof charger, and shown in Fig. 1～Fig. 5, described dustproof charger comprises: shell 100, dust cap 10, USB socket 26, USB socket 26 is arranged in the opening 25 of shell 100, dust cap 10 covers opening 25, and dust cap 10 is flexibly connected with shell 100.
By shown in Fig. 1 to Fig. 2, dust cap 10 further comprises slide plate 11, projection 12, in shell 100, be provided with spring 23 fixing springs 24, first end that extends of spring 24 withstands shell 100 inwalls, the removable connection of side of the second end and dust cap 10, promoting dust cap 10 can torsionspring 24, decontrols 10 springs of dust cap 24 and promotes dust cap 10 closures.
Be more preferably, promote dust cap 10, be provided with concave surface 20 on shell 100, can expose projection 12 and with finger, push dust cap 10 open better, the surface of preferred concave surface 20 is fan-shaped.Be more preferably, when closing, closed place adopts " U " type structure towards dust cap 10, when dust cap 10 cuts out, slightly covers opening 25 edges, guarantees closure.
The limit of the cross section of opening 25, in the outer on each limit of cross section of USB socket 26, coordinates with the longitudinal dual-side of dust cap 10.The shape of the wall position difference fitting projection 12 of opening 25 and USB socket 26, when projection 12 comes to the end, in Fig. 1, the horizontal side of dust cap 10 is preferably concordant with the inwall of opening 25, at least should not be less than this inwall, when USB plug enters USB socket 26, can keep better planarization, meet the interior space of a USB socket standard.
The limit of the cross section of opening 25 outside each limit of cross section of USB socket 26, with dust cap 10 longitudinally dual-side coordinate.The external diameter of opening 25 is slightly larger than USB socket 26, reserves the space come and can cover opening 25 when the fastening by dust cap 10 sides, thereby blocked the dust, metal fragment, water droplet etc. that enter USB socket 26, affects the foreign material that circuit is unobstructed.
As shown in Figure 1B, preferred shell 100 shapes of the utility model are hexagon cylinders, are positioned at the back side.Correspondingly, coordinating the preferred described top of USB socket 26 is plane, and the length of projection 12 and the horizontal edge appearance of opening 25 are same, and above-mentioned dust cap 10 can slide on the edge having a common boundary in opening 25 and USB socket 26.In the bottom of shell 100, be provided with plug 31, the external diameter mated plug 31 of the bottom 30 of shell 100.The size of bottom 30 compared with little be to insert in order to have influence on because the engaged position of other plug 31 is wide described dustproof charger on some sockets, the length lower limit of this bottom 30 can be with reference to the thickness of common three-pin plug.As the second choice of opimization, scheme that can alternative is, plug 31 can be vertical with described bottom, can be set to stir pack up, and protects described plug to prevent from falling impaired.
In the utility model, also have the second embodiment, the opening 25 of shell 100 is connected or is rotatably connected with dust cap 10 upsets.Dust cap is fixed on an other point of opening 25, and opening 25 places also have concave surface 20, and dust cap 10 can rotate, and dust cap 10 is rotated to opening 25 places, can will separate dust, and the used time is not pressed back opening 25.And the 3rd embodiment, fixedly dust cap 10, on one side in opening 25 1 sides, can overturn.While closing, dust cap 10 is turned to opening 25 places, can will separates dust, during use, with finger, from one side, dust cap 10 is pushed aside from opening 25, expose USB socket 26.As shown in Figures 3 to 5.
Preferably, dust cap 10 comprises flexible glue foundation ring, and the external diameter of described flexible glue foundation ring is interior identical with opening 25, and wherein dust cap 10 caps are bigger, with opening 25 form fit settings.In the time of need to using, dust cap 10 is opened, after being finished, cover, USB socket 26 can be filled in described flexible glue foundation ring, and dust cap 10 covers flexible glue foundation ring and opening 25 edges.
Dustproof charger in above embodiment, the material of shell 100 is resin materials, guarantees insulation characterisitic.Dust cap 10 is also used commaterial, also can select different insulating material.Shell 100 is tightly connected, but is also dismountable connection, and the part on top seals, and increases corner and can reduce the damage of being clashed into and causing.
By this projection 12, dust cap 10, when needs are pushed open, only needs the surperficial projection 12 with finger push dust cap 10, expose USB socket 26, the central authorities on the described top of shell 100.
In sum, the utility model, is stirred dust cap and can be stashed and expose interface at opening part by chimeric dust cap, and enforcement simple in structure is convenient, cover can prevent dust, waterproof, avoid metal fragment to enter and cause short circuit.Of the present utility model have dust cap at USB socket place, stir dust cap and expose socket, and the used time can not be closed when using power supply.Can when possessing dustproof effect, not affect the convenience of operation, keep the attractive in appearance and compact design of body.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
