Abstract

The anti-oxidant keyboard of a kind of water proof and dust proof, is made up of chassis, PCB module, protective cover, silica gel sealing cover, keycap; PCB module is contained on chassis, again protective cover is contained in above PCB module, silica gel sealing overlaps the square end surface of one end and coordinates with the square opening edge seal on protective cover, the corrugated body of the silica gel sealing cover other end is enclosed within the cylinder of keycap inside, the corrugated body end face of silica gel sealing cover and the inner bottom surface of keycap are sealed and matched, button boss in cylinder in keycap and PCB module closely cooperates, thus forms a complete anti-oxidant keyboard of water proof and dust proof.The benefit of the technical program is liquid, dust and air can not enter from the gap between keycap and PCB module in PCB module, therefore liquidproof, dust protection, air-prevention oxidation, has that protection is reliable, the advantage of long service life.

Description

The anti-oxidant keyboard of a kind of water proof and dust proof

Technical field

The utility model belongs to computer equipment field, is specifically related to the anti-oxidant keyboard of a kind of water proof and dust proof.

Background technology

Traditional mechanical keyboard is because have good click feel and reaction speed, and application surface is very wide, but on using, there is defect that is non-watertight, not dust-proof, not air-prevention oxidation.Non-watertight: if because of carelessness water is spread across on keyboard, likely causes keyboard circuit short circuit and damage; Not dust-proof: because of the distinctive circuit of mechanical keyboard, certain electrostatic to be produced, very easy dust suction, thus cause keyboard to amass completely a large amount of dusts; Not air-prevention oxidation: air can be entered by the gap between keycap and PCB module in PCB module, makes internal electronic component likely burn into oxidation in advance.

How to provide the better keyboard of a kind of barrier propterty just to become problem of the present utility model for this reason.

Utility model content

The purpose of this utility model is the anti-oxidant keyboard of open a kind of water proof and dust proof, solves prior art and can not carry out fine waterproof and dustproof, oxidation resistant problem.

The utility model is achieved in that the anti-oxidant keyboard of a kind of water proof and dust proof, is made up of chassis (1), PCB module (2), protective cover (3), silica gel sealing cover (4), keycap (5), PCB module (2) is contained on chassis (1), again protective cover (3) is contained in above PCB module (2), the square end surface (4.1) of silica gel sealing cover (4) one end coordinates with the square opening edge seal on protective cover (3), the corrugated body (4.2) of silica gel sealing cover (4) other end is enclosed within the inner cylinder of keycap (5), corrugated body (4.2) end face of silica gel sealing cover (4) and the inner bottom surface of keycap (5) are sealed and matched, button boss in cylinder in keycap (5) and PCB module (2) closely cooperates, thus the anti-oxidant keyboard of water proof and dust proof that formation one is complete.

In the anti-oxidant keyboard of a kind of water proof and dust proof, silica gel sealing cover (4) comprises square end surface (4.1) and corrugated body (4.2), square end surface (4.1) and corrugated body (4.2) connect together, and square end surface (4.1) is equipped with hole with corrugated body (4.2) middle part, and interconnects.

The utility model compares existing mechanical keyboard, has the following advantages:

First waterproof: when being spread across on keyboard by water because of carelessness, owing to having protective cover (3) and the silica gel sealing cover (4) between keycap (5) and protective cover (3) below keycap (5), it is inner that water can not enter PCB module (2).

Second point is dust-proof: on protective cover (3) with silica gel sealing cover (4), be provided with anti-static coating, dust can not be deposited in keyboard.

Thirdly anti-oxidant: silica gel sealing cover (4) is stuck between keycap (5) and protective cover (3) tightly, air is just not easy to enter PCB module (2) inside.

Embodiment

Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail.

The anti-oxidant keyboard of a kind of water proof and dust proof, be made up of chassis (1), PCB module (2), protective cover (3), silica gel sealing cover (4), keycap (5), wherein chassis (1), keycap (5), protective cover (3) one-shot forming by exploitation plastic injection mold; The bottom of PCB module (2) is PCB printed circuit board (PCB), and button boss is housed on PCB printed circuit board (PCB), and button boss is realized by design plastic mould; Silica gel sealing cover (4) is realized by design silica gel mould.

The anti-oxidant keyboard of a kind of water proof and dust proof, structure component relationship is as shown in Figure 1: be buckled in by keycap (5) above silica gel sealing cover (4), silica gel sealing cover (4) covers the square hole edge at protective cover (3), protective cover (3) is contained in PCB module (2), and PCB module (2) is contained in again on chassis (1).

In the anti-oxidant keyboard of a kind of water proof and dust proof, the structure of silica gel sealing cover (4) comprises square end surface (4.1) and corrugated body (4.2) two parts; Square end surface (4.1) is convenient to match with the square hole of protective cover (3) elevated regions, and anti-sealing, dust and air enter PCB module (2) inside by the square hole of protective cover (3) elevated regions; Corrugated body (4.2) has elastic telescopic function, when keycap (5) is depressed, the corrugated portion of corrugated body (4.2) is compressed, when keycap (5) resets under spring force, the corrugated portion of corrugated body (4.2) also resets simultaneously, the end face of corrugated body (4.2) withstands on the inner bottom surface of keycap (5) all the time tightly, and it is inner that anti-sealing, dust and air enter into PCB module (2) by the gap between corrugated body (4.2) end face and keycap (5) inner bottom surface.

To the surface spraying anti-static coating of protective cover (3) and silica gel sealing cover (4).Like this, dust would not be adsorbed onto on the surface of protective cover (3) and silica gel sealing cover (4).

In the anti-oxidant keyboard of a kind of water proof and dust proof, owing to being equipped with silica gel sealing cover (4) between keycap (5) and protective cover (3), it is inner that air is just not easy to enter into PCB module (2), the non-oxidizability that can completely cut off the silver-plated position of contact, particularly internal component of the inner electronic device of PCB module (2), hardware and outside air well obtains to be strengthened greatly.

The occasion that the utility model is particularly suitable for bad environments uses, and has the advantage that handling safety is reliable, keyboard service life is long.
