Can require also can be higher and higher, just has one among these and is related to the waterproofness of electronic product.
So, what is water-proof function, usual water-proof function refer to routine use accident short-time contact to water or its
Its liquid, liquid will not penetrate into circuit board or electronic component and cause a performance of the failures such as short circuit damage.However,
Current silica gel push-button can only realize deformation, it is difficult to while realizing waterproof, to make troubles to using.
Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of dual anti-
Water silicon glue press-key structure, can effectively solve existing silica gel push-button can only realize the problem of deformation cannot realize waterproof simultaneously.
To achieve the above object, the utility model is using following technical solution:
A kind of dual water-proof silica-gel press-key structure, includes lower cover, component, silica gel part, upper cover and keycap；The lower cover
With an accommodating cavity, which is set in accommodating cavity；The keycap and upper cover are fixed together with silica gel part produced by insert molding,
Upper cover has a slot that deformation is pushed for keycap, which is located in slot, and the bottom of keycap passes through slot and is suspended from component
Top, the bottom peripheral edge of the silica gel part expose to all sides of upper cover and with all sides of accommodating cavity seal cooperation fix.
As a preferred embodiment, the bottom surface of the accommodating cavity, which is extended, support convex, and it is convex which is butted on support
In portion.
As a preferred embodiment, the component includes pcb board and the switch that is set on pcb board, the keycap
Bottom, which is extended, compresses column, compresses the surface that column is located at switch.
As a preferred embodiment, the bottom week side of the silica gel part is convexly equipped with annular convex closure, and the annular convex closure is under
Lid interference engagement.
As a preferred embodiment, the lower cover, upper cover and keycap are plastic material.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Known to scheme:
By the way that keycap and upper cover are fixed together with silica gel part produced by insert molding, so that having reached between keycap and upper cover
Hermetically sealed realization waterproof effect, and the bottom peripheral edge of silica gel part is cooperated to expose to all sides of upper cover and all sides with accommodating cavity
Sealing cooperation is fixed, and realizes deformation by silica gel part during pressing, moreover it is possible to guarantee waterproof, offer convenience to use.
For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair
The utility model is described in detail.
