Water resistant structure and electronic apparatus
View Patent ↗A water resistant structure includes a first member having a stepped portion at an opening thereof; a second member having a rib protruding from a back surface thereof; and a water-stop member having an elastically deformable water-stop portion at a tip of a second plate portion that extends upward from a first plate portion. The first plate portion is attached to a horizontal surface of the stepped portion by double-sided adhesive tape. The second plate portion faces a vertical surface of the stepped portion. The water-stop portion is spread along the vertical surface of the stepped portion. The rib is pressed into an inner side of the water-stop portion, and the water-stop portion is pushed against the vertical surface of the stepped portion and the rib.
1. A water resistant structure comprising:
a first member having a stepped portion at an opening thereof;
a second member having a rib protruding from a back surface thereof; and
a water-stop member having an elastically deformable water-stop portion at a tip of a second plate portion that extends upward from a first plate portion, wherein
the first plate portion is attached to a horizontal surface of the stepped portion by double-sided adhesive tape,
the second plate portion faces a vertical surface of the stepped portion,
the water-stop portion runs along the vertical surface of the stepped portion,
the rib is pressed into an inner side of the water-stop portion, and
the water-stop portion is pushed against the vertical surface of the stepped portion and the rib.
2. The water resistant structure according to claim 1 , wherein
the second plate portion of the water-stop member has a spring property, and is caused to push the water-stop portion against the rib by a restorative force exerted by the second plate portion consequent to elastic deformation of the second plate portion, pushing the water-stop portion against the vertical surface of the stepped portion due to pressing of the rib into the inner side of the water-stop portion.
3. The water resistant structure according to claim 1 , wherein
the water-stop member is connected to a ground.
4. The water resistant structure according to claim 1 , wherein
the water-stop member comprises a protrusion extending toward the vertical surface of the stepped portion,
a recess is disposed in the vertical surface of the stepped portion, and
an end of the protrusion is inserted into the recess.
5. An electronic device comprising
a water resistant structure comprising:
a first member having a stepped portion at an opening thereof;
a second member having a rib protruding from a back surface thereof; and
a water-stop member having an elastically deformable water-stop portion at a tip of a second plate portion that extends upward from a first plate portion, wherein
the first plate portion is attached to a horizontal surface of the stepped portion by double-sided adhesive tape,
the second plate portion faces a vertical surface of the stepped portion,
the water-stop portion runs along the vertical surface of the stepped portion,
the rib is pressed into an inner side of the water-stop portion, and
the water-stop portion is pushed against the vertical surface of the stepped portion and the rib.
6. The electronic device according to claim 5 , wherein
the second plate portion of the water-stop member has a spring property, and is caused to push the water-stop portion against the rib by a restorative force exerted by the second plate portion consequent to elastic deformation of the second plate portion, pushing the water-stop portion against the vertical surface of the stepped portion due to pressing of the rib into the inner side of the water-stop portion.
7. The electronic device according to claim 5 , wherein
the water-stop member is connected to a ground.
8. The electronic device according to claim 5 , wherein
the water-stop member comprises a protrusion extending toward the vertical surface of the stepped portion,
a recess is disposed in the vertical surface of the stepped portion, and
an end of the protrusion is inserted into the recess.
