Description

Optimize silica gel button of corner conductivity

Technical Field

The utility model relates to a keyboard equipment technical field, in particular to optimize silica gel button of corner conductivity.

Background

The keys of the film keyboard mainly comprise keycaps, scissor feet (an X-shaped support) arranged below the keycaps and silica gel keys, wherein the X-shaped support is used for fixing and stabilizing the keycaps and is matched with a film circuit layer (namely a flexible circuit board) arranged at the bottom. Referring to fig. 1, the silicone key is in the shape of an inverted bowl, and mainly includes a supporting portion 11, an elastic connecting portion 12, a pressing portion 13, and an inner pillar 14 disposed inside the pressing portion 13, the supporting portion 11 of the bowl opening is mounted on the thin film circuit layer, and the pressing portion 13 at the bottom of the bowl is used for contacting the keycap. When the key cap is pressed, the pressing part 13 of the silica gel key drives the inner column 14 to strike the thin film circuit layer so as to realize the conduction of the upper circuit and the lower circuit of the thin film circuit layer, and the elastic connecting part 12 of the silica gel key enables the pressing part 13 to reset and drives the inner column 14 and the key cap to reset.

The silicone key of the prior art shown in fig. 1 is formed integrally in a mold cavity by injecting silicone through an injection molding machine, and generally has a silicone hardness of about 40 degrees due to functional requirements, which has the disadvantages that the silicone hardness is relatively low, and the inner space of the silicone key is small, so that the diameter of the inner column 14 is relatively thin, which results in insufficient strength, the upper and lower lines are conducted after impacting a thin film circuit layer, which may cause a situation of delayed or even unable conduction, and particularly, it is more obvious when testing four corners, thereby causing poor conduction at the corners.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an optimize silica gel button of corner conductivity, including adopting the integrative fashioned button body that jets out of silica gel material, the button body is including connecting gradually and being supporting part, the elastic connection portion of bowl form and pressing the splenium, it is provided with T type through-hole to press the splenium axial, the through-hole is embedded to be equipped with T type inner prop just the inner of inner prop to press the inboard protrusion of splenium, the material hardness of inner prop is greater than the silica gel material hardness of button body.

Wherein, the supporting part is also provided with an air vent which is communicated with the inside and the outside.

The inner wall of the through hole of the pressing part is provided with a limiting convex ring, and the outer wall of the inner column is provided with a limiting groove corresponding to the limiting convex ring.

Through the technical scheme, the utility model discloses a with silica gel material integrated into one piece's inner prop replacement for the embedded inner prop that has higher material hardness on the silica gel button basis of current structure, it is more powerful to make inner prop striking thin film circuit layer when the silica gel button is pressed to improve the electrically conductive agility when the button is pressed by a wide margin, press electrically conductively and improve equally to the angle, make the button reaction more agile.
