Abstract
The utility model discloses a thin-film switch elastic sheet, which comprises a metal main body, wherein the metal main body has a circular arc section and pressing elasticity; a plurality of contact convex points protruding downwards are formed in the center of the lower surface of the metal main body; and each contact convex point has a shape of truncated cone and the area of lower surface thereof is less than that of the upper surface thereof. The thin-film switch elastic sheet is simple in structure; and the contact convex points are formed in the center of the lower surface of the metal main body to increase the contact area of the thin-film switch elastic sheet with a circuit board and ensure that the contact between the thin-film switch elastic sheet and the circuit board is good, so the use effect is good, the thin-film switch elastic sheet can be subjected to pressure for a long time without losing efficacy.
Description
Technical field
The utility model relates to a kind of thin film switch shell fragment, particularly a kind of thin film switch shell fragment that is provided with contact salient point on body.
Background technology
Thin film switch is widely used on the electronic product such as mobile phone, and the thin film switch shell fragment is an one vital parts, its quality quality even have influence on the performance of the electronic product that uses it.The thin film switch shell fragment that uses on the market tends to occur the phenomenon of elastic fatigue after long-time the use at present, when pushing thin film switch, because pushing of thin film switch shell fragment is not in place, cause loose contact between the circuit board of thin film switch and electronic product, thereby cause sizable puzzlement to the user.At this phenomenon, develop and a kind ofly make that contact is good, to stand the thin film switch shell fragment of pushing use for a long time be the industry exigence.
The utility model content
The purpose of this utility model is, provide a kind of simple in structure, on metal body, be provided with the thin film switch shell fragment of contact salient point, this contact salient point can increase the contact area between thin film switch shell fragment and the circuit board, make contacting well between thin film switch shell fragment and the circuit board, and stand the long-term use of pushing.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of thin film switch shell fragment, it comprises that a cross section is circular-arc and pushes flexible metal body, the center of the lower surface of described metal body is provided with the contact salient point of some downward protrusions, and described contact salient point is a frustum, and its lower surface area is less than upper surface area.
As further improvement of the utility model, described metal body is circular, and described contact salient point is three.
As further improvement of the utility model, described metal body is circular, and described contact salient point is four.
As further improvement of the utility model, described metal body is oval, and described contact salient point is three.
As further improvement of the utility model, described metal body is oval, and described contact salient point is four.
The beneficial effects of the utility model are: the utility model is simple in structure, by lower surface center contact salient point is set at metal body, make the contact area of thin film switch shell fragment and circuit board increase, guarantee that contact between the two is good, make result of use good, and make that the thin film switch shell fragment can stand to push use for a long time, avoid losing efficacy.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
