Abstract
The invention provides a metal elastic sheet (10), which is provided with an arc-shaped convex surface (12) and an arc-shaped convex surface (11), wherein a plurality of convex installing parts (111) are arranged on the arc-shaped convex surface (11) of the metal elastic sheet (10). The convex installing parts are arranged on the arc-shaped convex surface of the metal elastic sheet, the position deviation phenomenon of the metal elastic sheet can be effectively prevented, and the sensitivity of press keys adopting the metal elastic sheet is improved, so the service life of the press keys is prolonged.
Description
Technical field
The present invention relates to a kind of remote controller assembly, more specifically for applying in the remote controller and the matching used a kind of metal clips of the button of remote controller.
Background technology
Metal clips (metal dome) is commonly called as the young sheet of pot.It adopts ultra-thin 0.05mm ~ 0.1mm thickness, and the stainless steel material of Vickers hardness between 480 ~ 550 processed.Metal clips have contact steadily, conduction is strong, resilience is stable, all good several big advantage of feel.
Metal clips can play good switch and launch and control action because of its good conduction property between operator and product.Secondly metal clips possesses stable resilience force, can bring comfortable shake-up sense to the operator.Simultaneously, metal clips has pressing the life-span of overlength.Therefore, metal clips has for example obtained in the fields such as remote controller, refrigerator or television set using widely at the key device of household electrical appliance.
Join shown in Figure 1ly, Fig. 1 is the generalized section of metal clips in the prior art, combines shown in Figure 2ly simultaneously, and the operation principle of metal clips 10 of the prior art is that metal clips 10 is arranged on the outside conductive part 90 on the pcb board (not shown).
The user pushes button (not shown), button meeting extrusion metal shell fragment 10, and the central point of metal clips 10 is recessed, thereby makes it touch inboard conductive part 80, thereby forms the loop, and electric current passes through, thereby makes remote controller send the signal of a certain particular job state.When the user unclamps button, metal clips 10 resiliences, thus inboard conductive part 80 and outside conductive part 90 are broken off, form open-circuit condition, thereby make remote controller stop to send the signal of this particular job state.This inboard conductive part 80 is essentially the carbon slurry layer that is printed on the pcb board with outside conductive part 90.
In view of this, be necessary metal clips of the prior art is improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of metal clips, it can prevent the phenomenon of metal clips occurrence positions skew, improves the sensitivity of the button of using this metal clips, and improves the useful life of button.
For realizing the foregoing invention purpose, the invention provides a kind of metal clips, it has an arc convex and arc-shaped concave, said metal clips arc-shaped concave be provided with some portions that are convexly equipped with.
As further improvement of the present invention, the said portion of being convexly equipped with is at least circle.
As further improvement of the present invention, the said portion of being convexly equipped with is periphery in the center of said arc-shaped concave.
Compared with prior art; The invention has the beneficial effects as follows: through some portions that are convexly equipped with are set on the arc-shaped concave of metal clips; Can effectively must prevent the phenomenon of metal clips occurrence positions skew, improve the sensitivity of the button of using this metal clips, thus the useful life of having improved button.

Embodiment
Below in conjunction with each execution mode shown in the drawings the present invention is elaborated; But should be noted that; These execution modes are not limitation of the present invention; The function that those of ordinary skills do according to these execution modes, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Please join Fig. 3 and shown in Figure 4, Fig. 3 is the schematic perspective view in first kind of embodiment of a kind of metal clips of the present invention, and Fig. 4 is the cutaway view of a kind of metal clips shown in Fig. 3.In this execution mode, a kind of metal clips 10, this metal clips 10 are circular and have the sheet metal of arc convex 12.Be provided with five at arc convex 12 faces of this metal clips 10 and be arranged with portion 121.Simultaneously be provided with five and be convexly equipped with portion 111 at the arc-shaped concave 11 of this metal clips 10.Three, six the perhaps portions that are convexly equipped with 111 of greater number certainly are set.
In this execution mode, this is convexly equipped with portion 111 and can be circle, also can be square or other shapes.Simultaneously, this is convexly equipped with portion 111 and is periphery in the center of this arc-shaped concave 11.
Cooperate with reference to shown in Figure 2, the ring-shaped edge 101 of this metal clips 10 is arranged on the outside conductive part 90 that is printed on the pcb board, and directly contacts with this outside conductive part 90.The user pushes button (not shown), and metal clips 10 is recessed, thereby makes it touch inboard conductive part 80, thereby forms the loop, and electric current passes through, thereby makes remote controller send the signal of a certain particular job state.When the user unclamps button, these metal clips 10 resiliences, thus inboard conductive part 80 and outside conductive part 90 are broken off, form open-circuit condition, thereby make remote controller stop to send the signal of this particular job state.
In the process of or resilience recessed at metal clips 10, several of arc-shaped concave 11 settings of this metal clips 10 are convexly equipped with portion 111 when connecting or disconnecting circuit, can play the effect of location.So the button of remote controller after using for a long time, even some locational skews take place metal clips 10, can not have influence on the function of these metal clips 10 conductings or open circuit yet.
Second kind of embodiment of ginseng Fig. 5 and a kind of metal clips of the present invention shown in Figure 6.The difference of this execution mode and first kind of embodiment is, only be provided with five at the arc-shaped concave 11 of this metal clips 10 and be convexly equipped with portion 111, and 12 of its arc convex is not provided with any portion that is arranged with.
The listed a series of detailed description of preceding text only is specifying to feasibility execution mode of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent execution mode or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any Reference numeral in the claim be regarded as limit related claim.
In addition; Describing according to execution mode though should be appreciated that this specification, is not that each execution mode only comprises an independently technical scheme; This narrating mode of specification only is for clarity sake; Those skilled in the art should make specification as a whole, and the technical scheme among each embodiment also can form other execution modes that it will be appreciated by those skilled in the art that through appropriate combination.
