Embodiment 1

[0014] Such as figure 1 , 2 As shown, the basic components and assembly structure of the FPC switch of this embodiment are similar to the JP2009-4209 scheme proposed by Japan Aviation Electronics Industry Co., Ltd., wherein this embodiment is aimed at the three parts of the four-sided handle 2, the handle 3 and the rubber body 4. The structure is improved, such as image 3 , 4 As shown, in this embodiment, the bottom surface of the top wall of the surrounding turning handle 2 is provided with 12 grooves 22 in an equidistant circular row as a handle position, and the handle sheet 3 is provided with 4 fixing holes 31 and is curved in the shape of an arch bridge. circular metal sheet, four fixing holes 31 are arranged symmetrically at the roots of both ends of the circular metal sheet arch bridge with two as a group, and the boss 41 of the rubber body 4 is provided with corresponding to the fixing holes and used for 4 fixing stakes 42 for fixing the handle sheet 3 . Because t...

Embodiment 2

[0016] The basic components and assembly structure of the FPC switch in this embodiment are similar to the JP2009-4209 scheme proposed by Japan Aviation Electronics Industry Co., Ltd. In this embodiment, the structure of the three parts of the four-wheel handle 2, the handle 3 and the rubber body 4 is improved. But different from Embodiment 1, in this embodiment, the bottom surface of the top wall of the surrounding handle 2 is provided with 10 grooves 22 in an equidistant circular row as a handle position, and the handle sheet 3 is provided with 2 fixing holes and is in the form of an arch bridge. A curved circular metal sheet, two fixing holes are respectively symmetrically distributed at the roots of the two ends of the circular metal sheet arch bridge, and the boss 41 of the rubber body 4 is provided with a corresponding to the fixing hole and used to fix the handle sheet 2 fixed stakes.

Abstract

The invention relates to a flexible printed circuit (FPC) switch which comprises an all-round turning handle, a feel sheet and a rubber body, wherein a plurality of grooves which are circularly arranged at equal intervals and used as feel gears are arranged on the bottom surface of the top wall of the all-round turning handle; the feel sheet is a circular ring-shaped metal sheet which is provided with a plurality of fixing holes and bent in an arched bridge shape; fixing piles corresponding to the fixing holes are arranged on a boss of the rubber body and used for fixing the feel sheet; the cross sections of the grooves are rectangular; and the plurality of fixing holes are at least two fixing holes symmetrically distributed at the roots of two ends of the arched bridge of the circular ring-shaped metal sheet. The invention optimizes the structures of the all-round turning handle and the feel sheet, and changes the azimuth of the gap between the feel sheet and the grooves by the novel structures of the all-round turning handle and the feel sheet, so that the gap between the feel sheet and the grooves is in the Z-axis direction of the grooves, and the technical problem that the existing FPC switch is easy to loose in use is solved by using the pressing force of the internal structure of the FPC switch on the feel sheet in the Z-axis direction, and using the structural characteristics of the using sheet after structural improvement.

Description

technical field [0001] The invention belongs to the technical field of switches and relates to an FPC switch, which is applied to electronic products such as mobile phones and digital cameras. Background technique [0002] Electronic products such as ultra-thin mobile phones and digital cameras have limited space, so various components must be combined to save space, and the same is true for FPC switches applied to electronic products. FPC switches are commonly used devices in electronic products such as ultra-thin mobile phones and digital cameras. The application of FPC switches in electronic products such as mobile phones and digital cameras is one of the keys to realize the miniaturization of such electronic products. In order to make the FPC switch occupy as little space as possible, the existing technology has carried out technical research on the FPC switch and made some technical improvements. For example, Japan Aviation Electronics Industry Co., Ltd. proposed the JP...
