Abstract

A waterproof enclosure includes a first enclosure section and a second enclosure section. The first enclosure section has an opening along which a gasket is provided. The gasket has a body section and a lip section protruding from the body section. The second enclosure section is disposed opposite the first enclosure section. The second enclosure section has a planar surface and an inclined surface. The inclined surface of the second enclosure contacts the lip section of the gasket, and the body section of the gasket contacts the planar surface of the second enclosure section.

Claims

1. A waterproof enclosure comprising:

a first enclosure section including a gasket which is provided on a gasket installation portion provided along with an opening, the gasket including a body section and a lip section protruding from the body section; and

a second enclosure section including a planar surface which contacts the first enclosure section and an inclined surface which contacts the lip section of the gasket,

wherein the lip section is configured to have an angle equal or less than 90 degrees with respect to the planar surface.

2. The waterproof enclosure according to claim 1, wherein the angle of the lip section is greater than an angle of the inclined surface of the second enclosure section with respect to the planar surface of the second enclosure section.

3. The waterproof enclosure according to claim 2, wherein the gasket includes a convex part with respect to the opening of the first enclosure section and a linear part;

and the inclined surface of a first portion of the second enclosure section facing the convex part is set to have a smaller angle than a second portion of the second enclosure section facing the linear part.

4. The waterproof enclosure according to claim 2, wherein the gasket includes a concave part with respect to the opening of the first enclosure section and a linear part;

and the inclined surface of a first portion of the second enclosure section facing the concave part is set to have a greater angle than a second portion of the second enclosure section facing the linear part.

5. The waterproof enclosure according to claim 1, wherein the gasket includes a groove provided at a root of the lip section.

6. The waterproof enclosure according to claim 1, wherein an end portion of the lip section is positioned outward with respect to an inner periphery of the body section of the gasket before the inclined surface of the second enclosure contacts the lip section of the gasket.

7. The waterproof enclosure according to claim 1, wherein the gasket and the first enclosure section are integrally molded.

8. An electronic apparatus in which a waterproof enclosure is installed comprising;

a first enclosure section including a gasket which is provided on a gasket installation portion provided along with an opening, the gasket including a body section and a lip section protruding from the body section;

a substrate with an electric component housed in the first enclosure; and

a second enclosure section including a planar surface which contacts with the first enclosure section and an inclined surface which contacts with the lip section of the gasket,

wherein the lip section is configured to have an angle equal or less than 90 degrees with respect to the planar surface.
