JPS6352396A - Water-proof structure for enclosure - Google Patents

Abstract

PURPOSE:To obtain excellent water proofing effect by a simple structure by abutting a cassette cover against a plane facing to a plane fitted with an enclosure. CONSTITUTION:A square hole 11 for attaching and detaching a cassette is opened at the center of upper face of the enclosure, and small square holes 12 for fitting sagittal part of waterproof rubber are provided at several places on a recessed part for fitting to the peripheral edge of the square hole 11. The sectional form of the waterproof rubber is nearly U-shaped curved form, and formed to a square ring shape to fit to the recessed part for fitting in the peripheral edge of the square hole 11, and sagittal projections 21 for fitting are provided at some places on a face that is in contact with the enclosure 1. A cassette cover 3 is held so as to allow an abutting part 31 formed by bending perpendicular to the waterproof rubber 2 against the face of the waterproof rubber 2 that is not fitted to the enclosure 1. As the waterproof rubber 2 is nearly U-shaped curved form, it has cushioning property and makes contact pressure moderate and heighten water proofing effect. Further, by inserting the sagittal part of the waterproof rubber 2 to the square hole 11, slipping off is prevented and fitting is made simple.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention can be used for waterproofing the main body and lid of the housing of video and audio equipment. This relates to the waterproof structure of the casing.

2. Description of the Related Art An example of a waterproof structure of a conventional video cassette casing will be described with reference to the drawings. FIG. 3 is a cross-sectional view of the waterproof structure of a conventional video cassette case.

In FIG. 3, the waterproof rubber 12 is pressed against the throat cover 13 using a video force using a rubber presser plate 14.
In this case, the tips of round bottles 15 provided at various places on the video cassette cover 13 are melted and the head is rounded, and the holding plate 14 is used as a welding stop.

Problems to be Solved by the Invention However, with such a conventional structure, the video cassette 7
) The problem is that the waterproof rubber 12 comes off from the cover 13, and it takes a lot of man-hours to install it again, making it relatively expensive.

In view of the above-mentioned problems, the present invention aims to provide a waterproof structure for a casing that has a simple structure and an excellent waterproof effect.Means for solving the problemsThe present invention aims to achieve the above-mentioned objects. It is provided at the part where the cassette cover of the bidet cassette comes into contact with the cassette cover, and has a curved shape with a substantially U-shaped cross section, and is inserted into holes formed at multiple locations on the surface that comes into contact with the casing. has an elastic body integrally formed with an arrowhead-shaped protrusion, the elastic body is fitted into the casing, and the cassette cover is brought into contact with a surface opposite to a surface fitted with the casing. It is constructed to have a waterproof function.

Effects According to the present invention, the cross-sectional shape of the elastic body at the portion that contacts the cassette cover is curved in a substantially U-shape to provide a cushion note, so that the contact pressure with the cassette cover is made appropriate. And it has improved waterproofing effect. In addition, the elastic body should have arrowhead-shaped tips at multiple locations on the surface that comes into contact with the housing, and the arrowheads should be inserted and fitted into the six holes provided opposite the housing to prevent removal. This makes installation with the video cassette M body simple and easy.

In this way, the waterproof rubber is fixed to the casing, so it does not come off, and the number of man-hours required for installation can be reduced.

EXAMPLES Below, the waterproof structure of the casing according to the examples of the present invention will be explained with reference to the drawings. FIG. 1 is an exploded perspective view of a waterproof structure of a housing according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing the deaf in a fitted state so as to exhibit a waterproof function. In FIGS. 1 and 2, 1 is an integrated video cassette (hereinafter referred to as a housing) of a video cassette recorder for field use, and a square hole 11 for attaching and detaching the cassette is bored in the center of the top surface. Small square holes 12 are provided in several fitting recesses on the peripheral edge of the hole 11 into which arrowheads of waterproof rubber are fitted.

Reference numeral 2 denotes waterproof rubber, which has a substantially U-shaped cross section and is formed into a square ring shape so that it can fit into the fitting recess at the peripheral edge of the square hole 11.

Arrowhead-shaped protrusions 21 that fit into the housing 1 are provided at some places on the surface that comes into contact with the housing 1. Reference numeral 3 designates a cassette cover, which is held such that a contact portion 31 formed by bending perpendicularly to the waterproof rubber 2 contacts the surface of the waterproof rubber 2 that is not abutted and fitted with the casing 1.

With the above configuration, the waterproof rubber 2 has a substantially U-shaped curve, so it has a waterproof property.

The contact pressure with the Caseno cover is optimized and the waterproof effect is enhanced. In addition, since the arrowhead-shaped tip fitting portions of the waterproof rubber 2 are provided at multiple locations on the surface that contacts the casing, facing the square holes 11, these arrowhead portions are inserted into the square holes 11 and fitted. This prevents it from being pulled out and makes it extremely easy to attach it to the housing 1.

Effects of the Invention As described above, according to the present invention, the waterproof effect is large, and
It is possible to obtain the effect that the waterproof rubber is easy to attach and does not come off easily.
