Key with metal luster

Abstract

The invention relates to a kind of depressed key with the metal luster. The plastic outer layer has some transparency and its thickness is between 0.1 and 1mm. The thickness of the rubber inner layer is between 0.3 and 0.5mm. The metal layer is between the second surface of the plastic outer layer and the third surface of the rubber inner layer and used to reflect ray of light. The thickness of the metal layer is between 0.2 and 20 mum. The depressed key possesses pliability. The weight is light; the thickness is weak; the weather resisting property and the drug tolerance is nice; the process is simple; the cost is low; the surface is hard to abrade and to remain fingerprint.

Description

technical field [0001] The invention relates to a button with metallic luster. Background technique [0002] see figure 1 , Figure 2A and Figure 2B As shown, the existing metal key is mainly to directly form the key 91 available for pressing on a metal sheet 90. With such a design, the key has sufficient strength and flexibility, and is suitable for small-sized portable communication devices ( For example: integrated keys for mobile phones, notebook computers, personal digital assistants, etc.). [0003] The existing metal buttons have the following disadvantages: [0004] 1. The weight is too heavy and the thickness is thick. All kinds of portable communication devices (such as mobile phones) on the market are generally required to be light, thin, short, and small. Although the existing metal buttons have a simple structure, if they want to produce better flexibility, they need a certain degree of flexibility. Thickness, relative weight is too heavy. [0005] 2.

AI Technical Summary

Problems solved by technology

All kinds of portable communication devices (such as mobile phones) on the market are generally required to be light, thin, short, and small. Although the existing metal buttons have a simple structure, if they want to produce better flexibility, they need to have a certain degree of flexibility. Thickness, relative weight is too heavy

[0005] 2. Poor surface weather resistance and drug resistance

The existing buttons are made of metal. If they are often used outdoors (especially in rainy days) or in wet construction sites, the metal buttons are easily corroded by water, humidity or chemical solutions.

[0006] 3. Difficult to process and high cost

For buttons made of metal, it is necessary to make a metal sheet with a predetermined thickness first, and then perform multiple processes such as chemical etching, electroplating, painting, protective layer, stamping, etc., which is not easy to process. In addition, the recent rise in international steel prices will inevitably increase the cost

[0007] 4. The surface is easy to oxidize or leave fingerprints

Existing metal buttons are easily oxidized or scratched when pressed for a long time or rubbed against foreign objects (such as clothes or bags), the protective layer is easy to fall off, and fingerprints are easy to remain, causing the surface to be blurred and lose luster
