The embodiment of the present application provides a kind of USB socket.Reference picture 4a, the USB socket include USB tongue pieces, the USB tongues Chip architecture includes tongue piece body 20 and tongue piece root 30, and the tongue piece body 20 along length bearing of trend include plug section L1 with And lengthening section L2, the plug section L1 is used for and Plug contact, the lengthening section L2 do not contact with the plug, the tongue piece knot Structure also includes multiple pins 40 (such as USB golden fingers).Wherein, multiple pins 40 are parallel along the length bearing of trend of tongue piece body 20 Set (preferably, equidistantly be arrangeding in parallel), and the multiple pin 40 is encapsulated in the tongue piece body 20 and tongue piece root 30 It is interior；The first surface of the plug section L1 is (see Fig. 4：Lower surface) be provided with it is one-to-one multiple recessed with multiple pins 40 Groove, the groove is used to accommodate the pin 40, and the pin 40 is located at the part of the plug section L1 close to described first Expose tongue piece body 20 in the side on surface (lower surface).

Preferably, the length of the lengthening section L2 is between 0.6-1.2mm.

Wherein, the pin 40 is for example including for the power supply terminal for connecting mainboard and USB connector and some conducting ends Son.It is worth noting that, multiple pins 40 herein are a rule conductiving metal strip, pin is complete connection in itself, not interrupted , pin 40 is divided into the part for being encapsulated in tongue piece body 20 and tongue piece root etc. herein, it is only for convenient to describe, just In understanding.

In addition, tongue piece body 20 and tongue piece root 30 herein is insulating materials, because its shape has difference, therefore have During body is realized, it can be thought as on the basis of one piece of complete material by removing redundance or two by shaping Part is fixed together by certain way.Practical application can be handled preferentially as the case may be, however it is not limited to this Shen Please disclosed embodiment.

Alternatively, as shown in Figure 4 b, the one end of the lengthening section L2 away from the plug section L1 is around lengthening section L2 appearances Face includes the second groove 50, and second groove 50 adds close to the side of the plug section L1 to the plug section L1 with described Long section L2 junction has the first specific range.

Specifically, first specific range is for example between 0.3mm-0.9mm, for ensureing when there is USB plug insertion, Second groove 50 will not be covered by USB plug, i.e., close to the position of tongue piece root 30 beyond the insertion end of USB plug.

Alternatively, as illustrated in fig. 4 c, the one end of the lengthening section L2 away from the plug section L1 is around lengthening section L2 appearances Face includes first convex tendon 60 of circle, and first convex tendon 60 forms water lock groove 70, first convex tendon with the tongue piece root 30 60 to the plug section L1 and lengthening section L2 junction has the second specific range.

Specifically, can also for example be used with reference to the first specific range, second specific range between 0.3mm-0.9mm It will not be blocked in guarantee when there is USB plug insertion, i.e., close to the position of tongue piece root 30 beyond the insertion end of USB plug Put, while be unlikely to too close tongue piece root 30 again so that dirt, liquid do not have deposition space.

Further, intersections of the plug section L1 and lengthening section L2 positioned at the lower section of pin 40 includes one Inclined-plane with special angle (being, for example, 45 degree).

The concrete application of the embodiment of the present application is, for example,：

Mobile phone connects the USB socket of charging wire plug, in practical application, needs often plug charging to charge the phone Line, frequently repeatedly plug causes the waterproof coating on USB socket top layer to be destroyed, and in the course of time, dirt liquid is at USB socket inwall and angle Fall alluvial so that pin would be at the moist environment of comparison and ultimately result in USB socket damage.Therefore the application passes through to structure Improvement so that positioned at the pin 40 of tongue piece body 20 be located away contact hydrops tongue piece root 30, while as far as possible reduce USB Destruction of the plug to USB socket mouth waterproof coating.

Reference picture 4a, more than the tongue piece 0.6-1.0mm of USB socket is lengthened to form lengthening section L2 so that on whole tongue piece The plug section L1 that is exposed of pin 40 outside move " hanging ", allow pin 40 to be in the environment for being beneficial to dry.Wherein, L0 sections are Guide section, for showing that tongue piece body 20 and USB socket mouth remain with exceptional space.Comparison diagram 1 and Fig. 4 a- Fig. 4 c can be seen Go out, the USB pins that the application provides include lengthening section L2, and the pin 40 of lengthening section is wrapped in tongue piece body 20 (insulating materials) It is internal.

On the basis of above structure is improved, a ring lock can also be designed between lengthening section L2 and tongue piece root 30 Tank, lengthening section L2 outer surfaces are looped around, cause hydrops, or some very obstinate residues to become silted up even if waterproof coating is destroyed Product, also they can be locked in the position of tongue piece root 30 and avoid its alluvial on the surface of pin 40 and corrode the latter.

Specifically, the ring lock tank includes two kinds of implementations：

Mode one：A circle groove is dug out in lengthening section L2, as water lock groove.Wherein, the cross sectional shape of the groove can select Can be realized with any industry and be easy to dust and hydrops deposition shape.

Mode two：In the circle convex tendon of lengthening section L2 arrangements one, water lock groove is formed with tongue piece root.Wherein, the size of convex tendon is simultaneously It is not particularly limited, can designs according to the actual requirements, the interface of convex tendon can be U-typed or semicircle, can also be square Shape, the application are not limited.

Compared with prior art, the application to the major general that is improved to of tongue piece structure by bringing following effect：

Ensure pin segment away from dirt liquid alluvial position first；Pin is set to be in hanging position simultaneously, even if it is also easy to be stained with water dust Dry；

Secondly, when USB plug rubs with tongue piece, even if there is a little dirt liquid, also pushed to the tongue piece root of USB socket by plug There is no the position of pin, so protect pin not to be corroded well；

Finally, after pin is hanging outward, friction of the USB seat tongue pieces root originally with plug has not existed, well protection Tongue piece root dirt liquid easily deposits the waterproof coating of position, allows liquid and dust to be difficult to survive herein, allows root to protect always Hold clean environment.Even if because placed angle reason result in ponding, as long as picking up mobile phone use, USB socket mouth down water Pearl will slide, will not the long-term alluvial in the inside again.

Another USB socket that the embodiment of the present application provides is improved USB socket inwall in structure, in USB Socket inner walls set raised：

Bulge-structure form one：The parallel plug orientation of outer casing inner wall surrounding sets the second convex tendon；

Bulge-structure form two：Design salient point in outer casing inner wall surrounding Plug contact face.

Fig. 5 a- Fig. 5 e show a kind of structure of USB socket including the first bulge-structure form, the USB socket bag Housing, and above-mentioned USB tongue piece structures are included, and the inner walls include some the second convex tendons 80, second convex tendon 80 Set parallel to plug orientation.The number of convex tendon is, for example, opposing upper and lower two surface of the inner walls parallel to tongue piece body Symmetrically, three the second convex tendons 80 are respectively arranged with.Also, for ease of production, this three convex tendons equidistantly arrange, it is preferable that three The length of bar convex tendon is identical.Because size is smaller, therefore housing both sides inwall is symmetrical, sets second convex tendon 80 respectively.It is optional Ground, and the height of second convex tendon 80 is between 0.03-0.05mm.

It is worth noting that, number, set-up mode and length of second convex tendon 80 etc. are not limited to Fig. 5 a- Fig. 5 e It is shown, can be according to being actually needed reasonable setting.

Reference picture 6a- Fig. 6 e show the structural representation of another USB socket with bulge-structure form two, should The inner walls of USB socket include two row's bulge-structures, and each row includes multiple salient points 90, and (bump height is, for example, 0.03- 0.05mm).The row of the salient point 90, the number for the salient point often arranged and size can rationally be set as needed.

, can be by the way that the face face friction between USB plug and USB socket inwall be become into millet cake using said structure form Or upper thread friction, the friction destruction waterproof coating between USB socket inwall and plug is reduced, protects big face in USB Long-pending waterproof coating；Meanwhile reserve space in USB socket inner walls and USB plug inner body wall so that even if because placing Angle reason result in ponding, as long as picking up mobile phone use, the USB socket mouth down globule can flow out from space, without The long-term alluvial in the inside again, ensure the internal integrated environment that can not hide flood.

Alternatively, the USB socket housing outer surface is provided with for the seal 100 for sealing the housing (see Fig. 7 a- Fig. 7 b).

Wherein, the seal 100 can use gum cover (such as：Silica gel sheath), now, USB does not have path With the intercommunication of interior of mobile phone space, enter only surplus one position of USB of water route.Gum cover is designed in USB socket housing outer surface, is made All peripheral holes, hole position in addition to its socket is all closed by gum cover, allow USB socket can only by socket port and Extraneous intercommunication.So the feed liquor path of USB socket also by multi-faceted feed liquor become only from USB seat sockets feed liquor, enter dirt.Glue simultaneously Set all extrudes the Tibetan liquid space on USB peripheries so that for USB socket in addition to socket, other positions can not Zang Shui.

Further, the shell inner surface sets waterproof coating 110 (see Fig. 8 a- Fig. 8 b).

Wherein, the set-up mode of the waterproof coating 110 is, for example,：Spray waterproof coating or evaporation nano water-proof coating. With reference to figure 2, after the water inlet of USB socket mouth in most cases can tongue piece root 30 and pin 40 and USB socket inner walls it Between the grade position of gap 182 alluvial (unless flood), while the dust of outside is also liked and is mixed continuous accumulation with liquid In these positions.By spraying waterproof coating or evaporation nano water-proof coating in USB socket inner walls, after increasing waterproof coating Dirt liquid cannot recycle capillarity to penetrate into these positions so that hide pool and form one layer of waterproof membrane, even if so feed liquor does not have yet Method pierces these gaps or alluvial in these corners again.When the mobile phone that USB socket mouth is intake takes up use, USB socket mouth can down, and liquid can tumble out as roller, so as to play good waterproof action.
