Embodiment

In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.

The utility model interface protector comprises keeper and protection plug, wherein, keeper be fixed on the USB interface of devices such as mobile phone or other kinds interface around.The protection plug comprises buckle end and plug, and buckle end and keeper are clasped, and the whole protecting plug is fixed on the interface, and plug is made by soft materials and be corresponding with the position of interface, is used for docking port and seals.

Example mobile phone as shown in Figure 1 to Figure 3 has USB interface, and keeper has two, is respectively first keeper 11 and second keeper 12 that are arranged on interface 30 both sides.Preferably; first keeper 11 and second keeper 12 can all be sheet metal; be fixed on the both sides of interface 30 respectively by screw 40; as shown in Figure 9, first keeper 11 is also reserved the first buckle position 111 and the second bayonet socket position 112 that is used to embed the buckle end of protecting plug respectively with second keeper, 12 relative sides.

To shown in Figure 6, the protection plug also comprises housing 21, movable buckle 22 and elastic component 23 as Fig. 4, and plug 20 is fixed on the rubber base 24, and rubber base 24 is fixed on the housing 21.For example plug 20 can be fixed on the middle part in rubber base 24 fronts, several lock screws 50 that are positioned at week in rubber base 24 week are fixed on the back side of rubber base 24 on the housing 21, and movable buckle 22 and elastic component 23 are all between housing 21 and rubber base 24.Preferably, for movable buckle 22 and elastic component 23 are carried out location and installation securely, housing 21 also has cavity 214, and movable buckle 22 and elastic component 23 all are contained in this cavity 214, makes the whole protecting plug form an integral body.

Elastic component 23 is a spring, and the one end props up housing 21, and the other end props up movable buckle 22.Protection buckle end beyond the Great Wall has two, is respectively the first buckle end 221 and the second buckle end 211 that is arranged on the housing 21 that are arranged on the movable buckle 22.

Shown in Fig. 7-9; in the time of will protecting plug to be installed on mobile phone or other devices; elastic component 23 is compressive state; because elastic component 23 is against between housing 21 and the movable buckle 22; and the first buckle end 221 is located at movable buckle 22 is propped up end by elastic component 23 corresponding end; and the second buckle end 211 is located at housing 21 is propped up end by elastic component 23 corresponding end; therefore movable buckle 22 relatively moves with housing 21; the first buckle end 221 embeds the first buckle position 111 under the elastic reaction of elastic component 23; thereby be clasped with first keeper 11; the second buckle end 211 embeds the second buckle position 112 under the elastic reaction of elastic component 23, thereby is clasped with second keeper 12.Simultaneously, the plug 20 that is installed on the rubber base 24 is corresponding with the position of interface 30, and docking port 30 carries out seal protection, can prevent that impurity such as sealing or dust enter interface 30, has effectively avoided interface 30 to damage, and has ensured the operate as normal of all kinds of devices that have interface.

As shown in Figure 8, the installation and removal for the ease of the protection plug also have opening 212 on the housing 21, and movable buckle 22 also has button and draws portion 222, and button draws portion 222 to pass the outside that opening 212 stretches out housing 21.When needing to install the protection plug, the user can manually push button along the arrow C direction earlier and draw portion 222, makes the first buckle end 221 and the second buckle end 211 all be in retracted mode, so that will protect plug integral body to be placed on interface 30 places, simultaneously, the position of plug 20 is corresponding with interface 30; Then, the user unclamps button and draws portion 222, it is relative mobile that housing 21 and movable buckle 22 take place under the elastic reaction of spring, and the first buckle end 221 and the second buckle end 211 stretch out respectively and embed the first buckle position 111 and the second bayonet socket position 112, makes the protection plug be difficult for dropping; When needing dismounting protection plug, the user still draws portion 222 along arrow C direction pushing button, and this moment, the first buckle end 221 and the second buckle end 211 broke away from the first buckle position 111 and the second bayonet socket position 112 respectively, and the user can take out the protection plug like a cork.

Further, in order to strengthen the seal protection effect of plug 20 docking ports 30, the lower surface of movable buckle 22 is close to rubber base 24, and upper surface has the sliding surface 223 of inclination, and the inboard of housing 21 is provided with skewback 212, and this skewback 212 props up sliding surface 223.When the protection plug is installed; move to first keeper 11 under resilient force at movable buckle 22; thereby make in the process that the first buckle end 221 and first keeper 11 be clasped; skewback 212 is exerted pressure to movable buckle 22 simultaneously; make movable buckle 22 be pressed on the back side of rubber base 24 to moving relative to direction away from housing 21; certain elastic deformation takes place in rubber base 24 under the pressure effect of movable buckle 22, the plug 20 that is fixed on rubber base 24 fronts more closely is fitted on the interface 30.

The purposes of interface protector of the present utility model and protection plug is very extensive; for example can be arranged on the multiple electronic devices such as mobile phone, digital camera, notebook computer; the size of housing and plug, shape and material can be provided with flexibly according to the type of interface; can effectively protect the USB on all kinds of devices or other polytype data-interfaces or power interface; avoid foreign material to enter interface and cause interface to damage, guaranteed the normal use of device.

Above content be in conjunction with concrete execution mode to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
