Abstract

In order to provide excellent waterproofness at a low manufacturing cost to a seal structure comprising a housing to which a flexible wiring board ( 1 ) is inserted and a seal member ( 3 ) integrally formed on said flexible wiring board ( 1 ) for hermetically sealing a gap between said housing and said flexible wiring board ( 1 ), a whole surface of a sensor member ( 31 ) arranged on at least one side of said flexible wiring board ( 1 ) is coated by same material as is used in said seal member ( 3 ), at a time of integrally forming the seal member ( 3 ) on the flexible wiring board ( 1 ).

Claims (35)

1. A sealing structure comprising:

a flexible wiring board adapted to be inserted into a housing;

an elastic seal member integrally formed on said flexible wiring board, said seal member hermetically engaging said housing and hermetically engaging said flexible wiring board so as to form a hermetic seal of a gap between said housing and said flexible wiring board;

a sensor member arranged on at least one side of said flexible wiring board; and

a coating layer coating an entire surface of said sensor member, said coating layer being:

the same material as said seal member;

integral with said seal member; and

one-piece continuous with said seal member.

2. A sealing structure as claimed in claim 1 , wherein said sensor member is provided in a hinge portion of a cellular phone.

3. A sealing structure as claimed in claim 1 , wherein said seal member is constructed of a frame body shaped seal for sealing mating faces of said housing.

4. A sealing structure as claimed in claim 1 , wherein said seal member is constructed of a bush shaped seal installed to an insertion hole provided in said housing.

5. A sealing structure as claimed in claim 1 , wherein said seal member is constructed of a combination of a frame body shaped seal and a bush shaped seal.

6. A sealing structure as claimed in claim 2 , wherein said seal member is constructed of a frame body shaped seal for sealing mating faces of said housing.

7. A sealing structure as claimed in claim 2 , wherein said seal member is constructed of a bush shaped seal installed to an insertion hole provided in said housing.

8. A sealing structure as claimed in claim 2 , wherein said seal member is constructed of a combination of a frame body shaped seal and a bush shaped seal.

9. A sealing structure as claimed in claim 1 , wherein said seal member and said coating layer comprise an injection molded elastic member.

10. A sealing structure as claimed in claim 1 , wherein said seal member and said coating layer comprise a compression molded elastic member.

11. A sealing structure as claimed in claim 2 , wherein said seal member and said coating layer comprise an injection molded elastic member.

12. A sealing structure as claimed in claim 2 , wherein said seal member and said coating layer comprise a compression molded elastic member.

13. A sealing structure comprising:

a flexible wiring board adapted to be inserted into a housing;

an elastic seal member integrally formed on said flexible wiring board, said seal member hermetically engaging said housing and hermetically engaging said flexible wiring board so as to form a hermetic seal of a gap between said housing and said flexible wiring board;

a sensor member arranged on at least one side of said flexible wiring board; and

a coating layer coating an entire surface of said sensor member, said coating layer being:

the same material as said seal member;

integral with said seal member; and

one-piece continuous with said seal member,

wherein said sensor member is provided in a hinge portion of a phone,

wherein said seal member is constructed of one of:

a frame body shaped seal sealing mating faces of said housing;

a bush shaped seal installed to an insertion hole provided in said housing; and

a combination of said frame body shaped seal and said bush shaped seal, and

wherein said seal member and said coating layer comprise a molded elastic member.

14. A sealing structure as claimed in claim 13 , wherein said seal member and said coating layer comprise an injection molded elastic member.

15. A sealing structure as claimed in claim 13 , wherein said seal member and said coating layer comprise a compression molded elastic member.
