Abstract

The utility model discloses keys for a keyboard. The keys for a keyboard comprise key caps, iron sheets and a rubber substrate, wherein the rubber substrate is arranged on a circuit board, the key caps are arranged on the rubber substrate and the iron sheets are positioned at the inner part of the rubber substrate. The utility model simultaneously discloses a keyboard which comprises keys and a circuit board, wherein the keys are arranged above the circuit board, wherein the keys comprise the key caps, the iron sheets and the rubber substrate. The key caps are arranged on the rubber substrate, the rubber substrate is positioned above the circuit board and the iron sheets are positioned at the inner part of the rubber substrate. Through that the iron sheets and the rubber substrate are together formed, the jointing working procedure in manufacturing process is saved and the iron sheets and the rubber substrate can be tightly combined. Therefore, the looseness can not be generated and the hand feeling is good. In addition, the rubber substrate is added with the iron sheets, the iron sheets in the rubber substrate simultaneously have the function of electrostatic prevention and the iron sheets simultaneously also has the function of light prevention for the rubber substrate of which the facade is uneven and can not be printed.

Description

A kind of keyboard button and keyboard

Technical field

The utility model relates to a kind of keyboard button, relates in particular to a kind of keyboard button that comprises iron plate.The utility model relates to a kind of keyboard that comprises iron plate simultaneously.

Background technology

Along with the continuous development of mobile phone industry, the consumer is more and more higher to the requirement of cell phone appearance and material texture.The keycap and the gap between the keycap of many cell phone keyboard designs are very little on the market now, and " piano key " such as we are commonly called as claims again on " disjunctor key " that the gap has only 0.15～0.2mm between keycap and the keycap.The hardness of button rubber substrate itself can't can only be improved for keycap adds any bracing frame in so little gap on casing.Traditional cell phone keyboard button mostly is to adopt keycap to add the rubber substrate design, also can only reach 70 and the hardness of rubber is the highest, between key and key in the very little keyboard product in gap, if rubber hardness is not enough, and do not have any external support, after the assembling, be easy to cause button to sink, phenomenons such as projection, and directly have influence on the function and the feel of keypad.In order to address this problem, a lot of products have all adopted in design increases the method that supports, wherein the most frequently used is exactly to support with iron plate, as shown in Figure 1, its technological process is: the rubber substrate is by sulfidization molding, iron plate assembles after five metals stamp operation and fits on the rubber substrate, owing to bond together by glue at last, must be gapped between two kinds of materials, and under the situation comparatively strict to the thickness requirement of keyboard, for example: ultra-thin keyboard, the gap between iron plate and the rubber substrate will have a strong impact on thickness, and the feel of the product after the final assembling.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of keyboard button, and this keyboard is tightr with button iron plate and the combination of rubber substrate, make keyboard can not produce loosening sense, and feel is better.

Another technical problem to be solved in the utility model provides a kind of keyboard, and this keyboard iron plate and rubber substrate make keyboard can not produce loosening sense, and feel are better in conjunction with tightr.

In order to solve above technical problem, the technical solution of the utility model is:

A kind of keyboard button comprises keycap, iron plate and installation rubber substrate in the circuit board, and keycap is installed on the rubber substrate, and iron plate is positioned at the inside of rubber substrate.

Iron plate is parallel with the upper surface of rubber substrate.

The vertical range of iron plate and rubber substrate top surface is less than the vertical range of iron plate and rubber substrate lower surface.

Iron plate is close to the inboard of rubber substrate top surface.

Iron plate is close to the inboard of rubber substrate sidewall.

A kind of keyboard comprises button and wiring board, and button is installed in the top of wiring board, and wherein, button comprises keycap, iron plate and rubber substrate, and keycap is installed on the rubber substrate, and the rubber substrate is positioned at the top of circuit board, and iron plate is positioned at the inside of rubber substrate.

Technique effect of the present utility model is:

By with iron plate with the moulding of rubber substrate, not only save the one procedure in the fabrication schedule, and can make iron plate and rubber substrate in conjunction with tightr, middle very close to each other, therefore can not produce loosening sense, and feel is better.In addition, added the rubber substrate of iron plate, iron plate wherein has the effect of antistatic simultaneously, and for positive uneven, the rubber substrate that can not print, iron plate has also played the effect of shading simultaneously.

Fig. 2 is the utility model keyboard press-key structure schematic diagram.

Embodiment

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Please refer to Fig. 2.The utility model keyboard comprises keycap 1 with button, iron plate 2 and be installed in the rubber substrate 3 of wiring board top, and keycap 1 is installed on the rubber substrate 3, and iron plate 2 is positioned at the inside of rubber substrate 3 and parallel with the upper surface of rubber substrate 3.The vertical range of iron plate 2 and rubber substrate 3 upper surfaces is less than the vertical range of iron plate 2 with rubber substrate 3 lower surfaces.

With in the preferred embodiment of button, iron plate 2 is close to the inwall of rubber substrate 3 upper surfaces and is close to the inwall of rubber substrate 3 sidewalls at the utility model keyboard.

The utility model keyboard comprises button and wiring board, wherein button comprises keycap 1, and iron plate 2, rubber substrate 3 and circuit board, keycap 1 are installed on the rubber substrate 3, rubber substrate 3 is positioned at the top of circuit board, and iron plate 2 is positioned at the inside of rubber substrate 3 and parallel with the upper surface of rubber substrate 3.The vertical range of iron plate 2 and rubber substrate 3 upper surfaces is less than the vertical range of iron plate 2 with rubber substrate 3 lower surfaces.

In preferred embodiment of the utility model keyboard, iron plate 2 is close to the inwall of rubber substrate 3 upper surfaces and is close to the inwall of rubber substrate 3 sidewalls.

This keyboard is as follows with the technological process of button iron plate and rubber substrate:

Earlier iron plate is carried out stamp by pre-designed shape with the five metals punch press, then that stamp is good iron plate is put into the dies cavity of rubber substrate, and and mould between usefulness reference column fixed iron piece position, iron plate off normal when preventing moulding.Put into silica gel material again, carry out rubber substrate sulfidization molding.The cross section of product as shown in Figure 2 after the moulding.Iron plate is to be wrapped in the rubber substrate after the moulding, and both become one, need be in the assembling of fitting.And specification requirement is not high, need not add any new equipment in the processing procedure again and can finish.

This technological requirement is considered the design of the thickness and the reference column of iron plate in rubber substrate die design process, concrete size is different and different according to product.
