Electronic device having water and dust proof structure

Abstract

An electronic device with a water and dust proof structure which can be safely used in wet and dusty environments. The electronic device includes a first cover. A second cover is coupled with the first cover and houses an electronic circuitry in a space between the first cover and the second cover. A first gasket is formed to be integral with the first cover and has a receiving groove on a surface facing the second cover. A second gasket is formed to be integral with the second cover and has a first projection portion. The first projection portion protrudes to have a height greater than a depth of the receiving groove when the first cover and the second cover are separate, and the first projection portion is compressed and deformed to be in contact with a plurality of surfaces inside the receiving groove when the first cover and the second cover are coupled with each other.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit under 35 U.S.C. §119(a) of a Korean Patent Application No. 10-2009-0069028, filed on Jul. 28, 2009, the entire disclosure of which is incorporated herein by reference for all purposes.BACKGROUND[0002]1. Field[0003]The following description relates to an electronic device, and more particularly, to an electronic device with a water and dust proof structure which can be safely used in wet and dusty environments.[0004]2. Description of the Related Art[0005]Portable electronic devices such as mobile phones, personal digital assistants (PDAs), MP3 players, and laptops are designed to be easily used during travel. Accordingly, the portable electronic devices are more likely to be exposed to wet and dusty environments. If moisture or dust is introduced inside the electronic device, this may cause damage to an internal electronic circuitry, resulting in malfunction of the device. Therefore, such electronic devic...

AI Technical Summary

Benefits of technology

[0012]Accordingly, the first gasket and the second gasket are formed to be integral with the first cover and the second cover, respectively. Thus, unlike the conventional art, a procedure of inserting the gasket into a groove of a cover can be omitted. Therefore, an operator can assemble the first cover and the second cover easily and quickly.

[0013]In addition, the first gasket and the second gasket are in contact on a plurality of surfaces, thereby increasing sealing tightness between the first cover and the second cover. Thus, the water and dust proof performance for the electronic device can be improved.

Problems solved by technology

Accordingly, the portable electronic devices are more likely to be exposed to wet and dusty environments.

If moisture or dust is introduced inside the electronic device, this may cause damage to an internal electronic circuitry, resulting in malfunction of the device.

In the above structure, an operator should insert the gasket 13 into the groove 11A on the front cover 11 manually with precision, which is difficult and takes a significant amount of time to assemble.

In addition, an assembly error may occur due to the tolerances of the gasket 13 and the groove 11A.

As the result, a failure of precise insertion of the gasket 13 into the groove 11A may occur, or the gasket 13 is inserted while twisted into the groove 11A, thereby impairing water and dust proof capability.

Thus, there may be a limitation in enhancing the water and dust proof performance.

Accordingly, the water and dust proof structure described above may cause an increase of manufacturing time and a need of further after-sales services, and degradation of reliability of the electronic device.

In addition, the first gasket and the second gasket are in contact on a plurality of surfaces, thereby increasing sealing tightness between the first cover and the second cover.
