Abstract
The invention relates to a non-permeable minitype side key switch, which comprises a base, a cover sheet sheathed on the base, and a switch terminal. The switch terminal is injected on the base from the bottom part; an elastic sheet and a button component are arranged in the base; a locating hole is arranged on the cover sheet; a pressing part at the upper end of the button component stretches out from the locating hole; the lower end of the button component is contacted with the elastic sheet; when the pressing part is pressed, the lower end of the button component presses the elastic sheet to lead the elastic sheet to contact with the switch terminal so as to conduct the terminal; and the connected part between the button component and the base has a sealing structure. The non-permeable minitype side key switch can seal the part connected with the base through the button component or a sealing gasket made from a soft material so as to completely seal the inner cavity of the base and play excellent sealing effect; therefore, failure of the switch caused by that foreign matters like colophony and dust are permeated into the switch when the switch and a circuit board pass through reflow soldering can be effectively avoided.
Description
Technical field
The present invention relates to a kind of switch, refer to especially a kind of for the minitype side-pressing switch on portable digital product.
Background technology
The touch-switch using on the ultrathin consumption electronic products such as mobile phone, MP4, digital camera, operated by rotary motion is in product side, and requiring switch is also lateral operation.General switch is all lateral opening, and due to switch lateral operation, the opening of side cannot seal, and when switch and other electronic device are installed on wiring board, while crossing Reflow Soldering, the foreign matters such as rosin, dust easily enter switch inside, affect the conducting of product.
In addition, the position that switch is set due to above-mentioned electronic product will arrange opening, and the foreign matters such as dust are also easy to enter switch inside by opening, affect the conducting of switch.
Summary of the invention
The problem that the present invention need solve is to provide a kind of minitype side-pressing switch for the preventing dust infiltration on portable digital product.
For solving the problems of the technologies described above, the present invention realizes by the following technical solutions: a kind of non-permeable minitype side key switch is provided, comprise base, be socketed on cover plate and switch terminal on base, described switch terminal is embedded in base from bottom, shell fragment and button assembly are set in base, on described cover plate, establish location hole, press section, button assembly upper end is stretched out by location hole, button assembly lower end contacts with shell fragment, press press section, button assembly lower end compressing shell fragment makes its contact-making switch terminal realize terminal conducting; Described button assembly and base joint are hermetically-sealed construction.
A kind of concrete scheme is, described button assembly and base joint arrange gasket seal, and sealing pad is socketed on button assembly, and its edge is covering base edge at least.
Described button assembly below is provided with the projection playing the guiding role, and gasket seal correspondence position is provided with downward groove, and projection is placed in groove, and this projection and base madial wall offset.
Another kind of concrete scheme is that described button assembly adopts soft material to make the sealing realizing with base.
Below button assembly, open country is provided with the projection playing the guiding role, and this projection and base madial wall offset.
The prioritization scheme of above-mentioned concrete scheme is that described cover plate extends to base end face along base two relative side, at base end face middle part, converges and entangles base.
The concrete installing mechanism of cover plate and base is: on described cover plate, location hole both sides arrange respectively installing hole, on corresponding base, projection is set, base and cover plate socket, and two projections insert respectively in installing hole; Described base end face is also provided with the guide vane end stop for fixing cover plate, and guide vane end stop lays respectively at base end face edge, and described cover plate is provided with screens at base end face meet, and clamping matching limited post blocks cover plate.Described gasket seal both sides all extend to installing hole edge, at least cover installing hole edge.
Compared with prior art, the present invention has following remarkable result: this switch is side key switch, and compact conformation, reliability are high, are applicable to the ultrathin consumption electronic products such as mobile phone, MP4, digital camera; And shift knob position and base joint adopt hermetically-sealed construction, the base intracavity of switch is sealed completely, and while effectively avoiding switch and wiring board to cross Reflow Soldering, the foreign matters such as rosin, dust infiltrate through switch inside, and avoid in finished product use procedure, dust enters and causes switch failure.

Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the present invention is further described in detail.
As Fig. 1,2,3,4, the non-permeable minitype side key switch that the present embodiment discloses comprises a base 1, a cover plate 2, and installing hole 21,22 is set on cover plate 2, on corresponding base 1, projection 11,12 is set, base 1 is socketed with cover plate 2, and two projections insert respectively in installing hole.
On button assembly 5, be socketed with the gasket seal 6 that soft material (for example rubber) is made, sealing pad 6 sizes are suitable with base size, and gasket seal 6 edges cover base 1 edges will be provided with the base intracavity sealing of button assembly and shell fragment.Gasket seal 6 belows are provided with downward groove 61, and this groove 61 is placed in the projection of button assembly 5 lower ends, and one arises from base 1 madial wall offsets, and plays guide and limit effect.Gasket seal 6 both sides extend to installing hole 21,22 edges, and installing hole 21,22 edges cover are prevented from installing hole seepage foreign material.
In the present embodiment, cover plate 2 extends to base end face along base 1 two relative side, at base end face middle part, converges and entangles base.Cover plate 2 does not join at base end face meet, and gap is left in centre, is convenient to the assembling processing of cover plate and base.Base 1 bottom surface is provided with the guide vane end stop 16 for fixing cover plate, and guide vane end stop lays respectively at base end face edge, and cover plate is also provided with screens 26 at base end face meet in addition, and screens 26 coordinates limited post 16 that cover plate is blocked, and prevents that cover plate is loosening.Said structure is conducive to gasket seal 6 and base 1 to compress, and reaches better sealing effectiveness, also makes whole side key switch structure compacter simultaneously.
Also another embodiment of can taking of the present invention, is about to whole button assembly 5 and all adopts soft material to make, and the button assembly that soft material is made is when contact with base, can be fully and base agree with, base intracavity is sealed, play sealing function.The projection that guide and limit effect has been set equally below case assembly, all the other structures of switch are also identical with embodiment mono-.
Above-described embodiment is the preferred version that the present invention realizes; and indefiniteness is exhaustive, under same idea, the present invention can also have other variations, it should be noted that; without departing from the inventive concept of the premise, any apparent replacement is all within protection range of the present invention.
