Abstract
The embodiment of the utility model discloses a spacer structure for a metal thin film switch. The metal thin film switch is provided with metal resilient sheets; the main body of the spacer structure is an insulating layer; through holes for containing the metal resilient sheets are arranged on the insulating layer; the through holes are grouped pairwise; and the through holes in the same group are communicated with each other by a venting groove. By using the technical means that the through holes for holding the metal resilient sheets are arranged on the insulating layer and the venting grooves for communicating the two through holes in the same group are further arranged, the spacer structure for the metal thin film switch and the metal thin film switch using the same achieve the technical effects of simple structure, good hand feel and high sensitivity in keying operation.
Description
Technical field
The utility model relates to the thin film switch field, relates in particular to a kind of metal dome switches with spacer structure and use the metal dome switches of this structure.
Background technology
Continuous development along with technology; Portable type electronic product particularly is provided with the electronic product of operation push-button; Like more and more miniaturizations and more and more thinner of product such as mobile phone, PDA, MP3 and remote controllers, and metal dome switches has adapted to this trend just and become and become more and more popular.
After the metal clips of the metal dome switches that existing portable type electronic product uses depresses,, can influence user's operating handle, even can cause the malfunctioning situation of button to take place because gas can't be discharged smoothly.
The utility model content
The utility model embodiment technical problem to be solved is, provides a kind of metal dome switches with spacer structure and use the metal dome switches of this structure, and is simple in structure, good hand touch, and button operation is highly sensitive.
In order to solve the problems of the technologies described above; The utility model embodiment has proposed a kind of metal dome switches and has used spacer structure; Said metal dome switches is provided with metal clips, and said spacer structure main body is an insulating barrier, offers the through hole that is used for ccontaining said metal clips on the said insulating barrier; Two of said through holes are one group, and through hole on the same group is connected with air discharge duct.
Further, said air discharge duct width is 0.5 millimeter ~ 1.5 millimeters.
Further, said air discharge duct width is 1 millimeter.
Correspondingly; The utility model embodiment also provides a kind of metal dome switches of using said spacer structure; Comprise the spacer layer that adopts said spacer structure; Be equipped with said metal clips in the said through hole, said metal dome switches also comprises insulation screen and the optical waveguide layer that stacks gradually the press section one side that is covered in the corresponding said metal clips of said spacer layer.
Further, said metal dome switches is pasted on the surface of mould release membrance.
The metal dome switches of the utility model embodiment with spacer structure and the beneficial effect of using the metal dome switches of this structure is: offer the through hole that is used for ccontaining metal clips through adopting on the insulating barrier; Also offer the technological means of the air discharge duct of connection two said through holes on the same group; Thereby reached simple in structure; Good hand touch, the technique effect that button operation is highly sensitive.
Description of drawings
Fig. 1 is the generalized section of the metal dome switches of the utility model embodiment.
Fig. 2 is the sketch map of the spacer structure of the utility model embodiment.
Embodiment
Please refer to Fig. 1 ~ Fig. 2, the metal dome switches of the utility model embodiment is pasted on the surface of mould release membrance 10, comprises spacer layer 20, insulation screen 30 and optical waveguide layer 40.Said metal dome switches is provided with metal clips 21.
Make good metal dome switches and stick on the mould release membrance 10, during installation mould release membrance 10 is removed, metal dome switches is sticked on the portable type electronic product corresponding printed circuit board (PCB) or FPC.
The main body of spacer layer 20 is an insulating barrier, offers the through hole 23 that is used for ccontaining said metal clips 21 on the said insulating barrier, also offers the air discharge duct 25 that is communicated with two said through holes 23.Wherein, two said through holes 23 are one group, and through hole 23 on the same group is connected with an air discharge duct 25.Said air discharge duct 25 width are 0.5 millimeter ~ 1.5 millimeters, and in this execution mode, said air discharge duct 25 width are 1 millimeter.Through hole 23 by said spacer structure makes that with air discharge duct 25 through hole 23 two corresponding metal dome switches form two switch air chambers that seal, are communicated with on the same group; When pushing a thin film switch; Air in this switch air chamber is squeezed and flow in other air chamber that is communicated with this air chamber; Make metal dome switches have good venting quality, thereby guarantee thin film switch good hand feeling and higher Operational Figure Of Merit.
Said insulation screen 30 and optical waveguide layer 40 stack gradually press section 210 one sides that are covered in said spacer layer 20 corresponding said metal clipss 21.Said insulation screen 30 has the shielding electromagnetic wave interference function, and it is covered in said spacer layer 20, has played to intercept the effect that extraneous dust gets into the operating space, makes metal dome switches have good closure, dust tightness and anti-electromagnetic interference property.
Said optical waveguide layer 40 adopts the optical clear film to process, and has the function that the point-source of light of led light source is converted to area source.
The above is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection range of the utility model.
