Abstract
A pressing structure used for a keyboard is characterized in that an included angle is arranged between a front segment and a middle segment of a stainless steel sheet, an included angle is arranged between the middle segment and the rear segment of the stainless steel sheet, and a circular bump is punched downwards at the middle segment of the stainless steel sheet. A positioning pressure plate is arranged on the front segment of the stainless steel sheet, and a keycap is connected with the rear segment of the stainless steel sheet. The front segment of the stainless steel sheet is arranged on a circuit board, at the rear segment of the stainless steel sheet and based on a lever principle, the circular bump at the middle segment of the stainless steel sheet obtains a larger downwards applied force, thereby pushing a lower elastic contact switch to be contacted and conducted. After the rear segment of the stainless steel sheet is released, the elasticity of the stainless steel sheet is recovered, the circular bump is separated from the elastic contact switch, the elastic contact switch is reset, and the circuit is turned off, thereby finishing one time pressing circulation. By a through hole arranged at the adjacent position of the front segment and the middle segment of the stainless steel sheet, the hand feeling when pressing can be improved. According to the utility model, the bent stainless steel sheet forms a lever, thereby reducing the thickness of the keyboard.
Description
Technical field:
The utility model relates to electricity field, relates in particular to switch, particularly keyboard, and concrete is a kind of pressing structure for keyboard.
Background technology:
In prior art, various control panels and notebook computer are using keyboard as input unit.But the more space of keyboard grabbing, make control panel and notebook computer be difficult to more frivolous, can't satisfy the demands of consumers.Simultaneously, the keyboard life-span is more limited, and cost is higher.
Summary of the invention:
The purpose of this utility model is to provide a kind of pressing structure for keyboard, and the described this pressing structure for keyboard will solve the technical problem in the more space of prior art keyboard grabbing.
This pressing structure for keyboard of the present utility model, comprise a stainless steel substrates, wherein, between the leading portion of described stainless steel substrates and stage casing, be provided with angle, be provided with angle between the stage casing of stainless steel substrates and back segment, in the stage casing of stainless steel substrates, punching press downwards has a boss point.
Further, the back segment of stainless steel substrates is parallel with the leading portion of stainless steel substrates.
Further, the upside of the leading portion of stainless steel substrates is provided with a positioning pressuring plate.
Further, the back segment of stainless steel substrates is connected with a keycap.
Further, the thickness of stainless steel substrates is between 0.2mm～0.5mm.
Further, the angle between stainless steel substrates leading portion plane and stage casing is 11 degree, and the stage casing of stainless steel substrates and the angle between back segment are 170 degree.
Further, the stainless steel substrates leading portion is fixedly connected on a circuit board, is fixedly installed a resilient contact switch on described circuit board, and described boss point is positioned at the upside of described resilient contact switch.
Further, the diameter of boss point be 1.0mm, highly for 0.5mm.
Further, the width in stainless steel substrates stage casing is less than the width of stainless steel substrates leading portion or stainless steel substrates back segment.
Further, be provided with a through hole in the adjacent in stainless steel substrates leading portion and stage casing.
Operation principle of the present utility model is: the leading portion of stainless steel substrates is on circuit board, back segment at stainless steel substrates, utilize lever principle, makes the boss point in stainless steel substrates stage casing obtain larger downward active force, thereby promote the resilient contact switch of below, make its contact conducting, after unclamping the stainless steel substrates back segment, stainless steel substrates elasticity is recovered, boss point breaks away from the resilient contact switch, the resilient contact switch resets, and circuit disconnects, and completes and once presses circulation.The through hole arranged in the adjacent in stainless steel substrates leading portion and stage casing, can improve the feel while pressing.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model utilizes a stainless steel substrates after bending to form lever, utilize the boss point in stainless steel substrates stage casing to promote the resilient contact switch on circuit board, make its contact conducting, the thickness of pressing structure is little, when using the property contact switch of 0.2mm～0.4mm stroke, the stroke of pressing structure can reduce to 0.5mm～0.9mm, thereby has reduced the thickness of keyboard.
The accompanying drawing explanation:
Fig. 1 is the plan structure schematic diagram of the pressing structure for keyboard of the present utility model.
Fig. 2 is the structural representation of the pressing structure for keyboard of the present utility model when normality.
Fig. 3 is the structural representation of the pressing structure for keyboard of the present utility model after pressing tooth.
