Embodiment
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
The invention provides a kind of portable terminal side switch water-tight device, as shown in Figure 1 and Figure 2, have housing 100 on the portable terminal, the side switch water-tight device comprises side switch body 200, sealing ring 300 and side switch hole 110.Wherein side switch hole 110 is positioned on the sidewall of described housing 100, described sealing ring 300 is interference fitted on the described side switch hole 110, has side switch groove 312 on the described sealing ring 300, the inboard of described side switch body 200 (towards a side of housing 100) has side switch post 210, and described side switch post 210 and described side switch groove 312 are connected.Make because sealing ring 300 is independent of housing 100, it is simple to make mould, low cost of manufacture, feasibility height.
As shown in Figure 1, the two ends of described side switch body 200 have grab 220, connect by sheet connecting portion 230 between described grab 220 and the described side switch body 200.As shown in Figure 2, described side switch body 200 is fixed on the described housing 100 by grab 220.Sheet connecting portion 230 has certain elasticity, is convenient to pressing of side switch body 200, but fitted seal circle 300 makes side switch body 200 returns simultaneously.
As Fig. 4, shown in Figure 5, described sealing ring 300 comprises colloidal silica 310 and steel disc 320.Described colloidal silica 310 has side switch groove 312, described colloidal silica 310 has the flange 311 that can be resisted against on housing 100 sidewalls at the openend of side switch groove 312, and the steel disc 320 that one deck is connected as a single entity covers the outside of madial wall and the described flange 311 of described side switch groove 312.Described colloidal silica 310 and housing 100 interference fit, play effects such as waterproof and dustproof, because colloidal silica 310 quality are softer, so adhere to one deck steel disc 320 at colloidal silica 310 it is finalized the design, also be convenient to steel disc 320 is squeezed in the purpose that reaches interference fit on the housing 100.Consult Fig. 3, flange 311 is resisted against on the housing 100, makes sealing ring 300 be difficult for displacement when being squeezed, and makes sealing effectiveness more stable.
Described sealing ring 300 manufacture crafts are as follows:
S001, with steel disc 320 full wafer punch formings, have several perforates on the every steel disc 320, sealing ring 300 quantity that the quantity of perforate and every steel disc 320 need to make equate.
S002, remove the burr on the steel disc 320.
S003, with the silica gel sheet oil pressure of steel disc 320 and corresponding size together.
S004, oil pressure steel disc 320 and silica gel sheet together is die-cut into finished product sealing ring 300.
As shown in Figure 1, because sealing ring 300 has flange 311, so the slot to make way 250 of described flange 311 embeddings of confession is set in the inboard of described side switch body 200.The inboard of described side switch body 200 is provided with rubber-like resilient coating 240, presses when putting in place at button like this, does not have the sensation that stops suddenly, increases the feel of button.
As shown in Figure 5,313 outsides, bottom of described colloidal silica 310 have outer lug boss 315, and when sealing ring 300 was squeezed, corresponding shell fragment contacted to touch the function of respective keys in outer lug boss 315 and the portable terminal.313 inboards, bottom of described colloidal silica 310 have inner convex platform 316, described inner convex platform 316 and described side switch post 210 lean (consulting Fig. 3).Described inner convex platform 316 and described outer lug boss 315 are arranged to truncated cone-shaped usually.Described inner convex platform 316 and outer lug boss 315 can increase the feel of pressing of side switch, make the weight of pressing more suitable, and paragraph sense is distincter.
As shown in Figure 5, between the sidepiece 314 of the bottom 313 of described colloidal silica 310 and colloidal silica 310 by being convenient to bottom 313 opposite side portions 314 along the elastic arm 317 of side switch groove 312 axial motions.313 inboards, bottom of described colloidal silica 310 have the groove 318 around described inner convex platform 316.When colloidal silica 310 was squeezed, elastic arm 317 can extend, and the length that groove 318 can increase described elastic arm 317 is set, make button to press feel better, can be not too short and have tangible obstruction sense because of elastic arm 317.Add a certain amount of sulphur in the described colloidal silica 310, increase the toughness of silica gel, toughness reguirements such as satisfy that side switch is pressed, fallen.
As shown in Figure 5, can have wedge angle 321 through die-cut steel disc 320, the position thickness that wedge angle 321 leans on the sidepiece 314 of described colloidal silica 310 and the described steel disc 320 is greater than other position of colloidal silica 310 sidepieces 314, can prevent or slow down wedge angle 321 effectively and puncture silica gel, to prolong the useful life of sealing ring 300.
Has the gap between described side switch post 210 and described side switch groove 312 madial walls.When colloidal silica 310 is squeezed, the sidepiece 314 of colloidal silica 310 is actionless, the bottom 313 of colloidal silica 310 can be along with the elongation of elastic arm 317 along the axial motion of side switch groove 312, at this moment side switch post 210 and side switch groove 312 between retain the gap and just can prevent that side switch post 210 and side switch groove 312 from rubbing, increase the button feel, prolong button useful life.
Should be understood that; the above only is preferred embodiment of the present invention; be not sufficient to limit technical scheme of the present invention; for those of ordinary skills; within the spirit and principles in the present invention; can be increased and decreased according to the above description, replacement, conversion or improvement, and all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection range of claims of the present invention.
