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.

 have a receiving groove formed on a surface facing the second cover; and 
   a second gasket formed to:
 be integral with the second cover and located at an outer region of a coupling surface of the second cover such that a protruding portion of the positioning rib can be in contact with the coupling surface of the second cover when the first cover and the second cover are coupled with each other; and 
 have a first projection portion on a surface facing the first cover, wherein 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 surfaces inside the receiving groove when the first cover and the second cover are coupled with each other. 
   
     
     
         6 . The electronic device of  claim 5 , wherein the first gasket further includes a second projection portion which is formed on the surface facing the second cover and is located further out than the receiving groove, and the second projection portion is compressed and deformed to be in contact with the second gasket when the first cover and the second cover are coupled with each other. 
     
     
         7 . The electronic device of  claim 6 , wherein the second projection portion is further formed to have a smaller sectional surface than that of the first projection portion. 
     
     
         8 . The electronic device of  claim 5 , wherein:
 the first projection portion is further formed to have a triangular sectional surface; and   the receiving groove has a flat bottom and each side wall inclined at the same angle as each side surface of the first projection portion.   
     
     
         9 . An electronic device with a water and dust proof structure, comprising:
 a first cover;   a second cover configured to:   be coupled with the first cover; and   house electronic circuitry in a space between the first cover and the second cover;   a first gasket formed to:
 be integral with the first cover and at least partially enclose an exterior surface of the first cover including a coupling portion of the first cover; and 
 have a receiving groove on a surface close to the coupling portion of the first cover; and 
   a second gasket formed to:
 be integral with the second cover and at least partially enclose an exterior surface of the second cover including a coupling portion of the second cover; and 
 have a first projection portion on a surface facing the first gasket, wherein 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 surfaces inside the receiving groove when the first cover and the second cover are coupled with each other.
