Abstract

PURPOSE: To enable waterproofing securely for those parts such as battery case which are frequently installed and removed by storing the annular part of waterproof members and lock tongue pieces in the groove part and stage part formed in an area of a device main body where an attachment member is installed and fixing the lock tongue piece by an indicated seal. CONSTITUTION: A waterproof packing 5 is stored in a groove part 1a formed inside a battery case installation part of a device cabinet 1. Also a stage part 1b is formed in the device cabinet 1 at a position where the lock tongue piece 5b of the waterproof packing 5 is located, continuously with the groove part 1a. Then the lock tongue piece 5b is stored in the stage part 1b, and fixed by a rated seal 6 so that it cannot be removed easily. In addition, when a battery case is installed on a main cabinet 1, the waterproof packing 5 is pressed and deformed by its end surface, and the waterproof packing is fitted closely to the groove part 1a of the main cabinet 1 to prevent the entry of water.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof device for portable electronic equipment such as a portable telephone device.

[0002]

2. Description of the Related Art A portable electronic device such as a portable radio or a mobile phone device may be provided with a waterproof structure in consideration of use in rainy weather or a place exposed to water. Such a conventional waterproof structure is, for example, a figure? The structure was as shown in. Ie figure? Shows a cross-sectional view of a portable electronic device such as a mobile phone device. In the figure, 101 and 102 are cabinets of the portable electronic device. A groove 101a is formed on the lower cabinet 101 over the entire circumference of the end of the cabinet, and a convex portion 102a is formed on the end of the upper cabinet 102 at a position facing the groove 101a.
Reference numeral 103 is a waterproof O-ring formed of rubber, synthetic resin, or the like. The O-ring 103 is a lower cabinet 1.
No. 01 groove 101a. In this state, the lower cabinet 101 and the upper cabinet 102 are tightened and fixed by screws or the like (not shown), whereby the O-ring 103 is deformed and water is prevented from entering through the gap between the cabinets 101 and 102.

[0003]

In the above-mentioned prior art,
If both cabinets are firmly fixed, a sufficient waterproofing effect can be obtained, but in a device having a removable battery, for example, the battery and the device body are frequently removed and attached. Since it is a thing that can not be firmly joined like screwing,
There is a problem that such a conventional technique cannot deal with the problem. That is, if the waterproofness between the battery case and the main body is not perfect, water will enter from the battery terminal portion. Further, due to the downsizing of the device, the depth of the groove for accommodating the O-ring is limited, and when such a conventional technique is used for waterproofing between the battery and the device body, the O-ring comes off when the battery is attached or detached. There was also a problem that it would end up.

[0004]

In order to solve the above-mentioned problems of the prior art, a waterproof device for a portable electronic device according to the present invention comprises a device body and an attachment member detachably attached to the device body. A ring portion provided between the attachment member and the apparatus main body and having substantially the same shape as the outer periphery of the attachment member, and a locking tongue piece integrally formed on the ring portion at a predetermined interval. A waterproof member having elasticity and a display sticker having an adhesive layer formed on the back surface, and the annular portion and the locking tongue piece of the waterproof member formed over the entire circumference of the position where the accessory member of the device body is mounted. The waterproof member is housed in the groove and the stepped part for housing, and the display seal is attached on the locking tongue to fix the waterproof member.

Further, the waterproof device for a portable electronic device according to the present invention is characterized in that the accessory member is a battery case for operating the main body of the device.

Further, the present invention is characterized in that the cross section of the annular portion of the waterproof member is polygonal.

[0007]

According to the first aspect of the invention, the annular portion and the locking tongue of the waterproof member are housed and locked in the groove and the step formed in the portion of the apparatus body where the accessory member is mounted. The tongue is fixed by the display sticker. When the attachment member is attached to the apparatus body, the waterproof member is pressed by the end surface portion of the attachment member to prevent water from entering through the clearance between the two devices.

Further, according to the second aspect of the invention, even in a battery case which is frequently attached and detached, water is completely prevented from entering through the gap, and water is introduced into the main body of the apparatus through the battery contact. Intrusion can be prevented in advance.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of a mobile phone device using the present invention in a battery mounting portion. In FIG. 1, 1 is a device housing and 2 is a battery case detachably provided in the device housing 1. The battery case 2 is locked by the lock means 3. 4 is an antenna.

FIG. 2 is a rear view showing a state in which the battery case 2 is removed from the apparatus housing 1. In the figure, 5 is a waterproof packing that is arranged around the entire circumference of the part where the battery case 2 is mounted, 6 is an adhesive seal on the back surface, and the product manufacturer, model name, certification number, etc. are on the front surface. Printed rating label, 7 is battery connection terminal, 8
Is a fixing screw.

As shown in FIG. 3, the waterproof packing 5 is formed of an elastic material in the same shape as the outer circumference of the battery case 2, and has an annular portion 5a having a circular or polygonal cross section and each side of the annular portion 5a. Locking tongue 5 formed at a predetermined position of the
b. In the present embodiment, the cross-sectional shape of the annular portion 5a is hexagonal and the diagonal line is compressed,
It is more waterproof.

FIG. 4 is a sectional view of FIG. 2, where FIG. 4A is a sectional view taken along line AA and FIG. 4B is a sectional view taken along line BB.
A cross section is shown. As shown in FIG. 4A, the waterproof packing 5 is housed in the groove portion 1 a formed inside the battery case mounting portion of the apparatus housing 1. Also, FIG.
As shown in FIG. 1, in the apparatus housing 1, a step portion 1b is formed continuously with the groove portion 1a at a portion where the locking tongue piece 5b of the waterproof packing 5 is located. 5b is housed and fixed by the rating seal 6 so as not to come off easily.

FIG. 5 is a sectional view showing a state in which the battery case 2 is attached to the main body housing 1. As shown in the figure, when the battery case 2 is mounted, the waterproof packing 5 is pressed and deformed by the end surface portion thereof, and the waterproof packing 5 is brought into close contact with the groove portion 1a of the main body housing 1 to prevent water from entering.

[0014]

As described above, in the waterproof device for a portable electronic device according to the present invention, the annular portion and the locking tongue piece of the waterproof member formed over the entire circumference of the position where the accessory member of the device body is mounted are provided. The waterproof member is stored in the groove and step for storing, and the display seal is affixed to the top of the locking tongue to fix the waterproof member. It is possible to ensure reliable waterproofing even in the exposed parts. Also, in such a device, a rating sticker for displaying the model name, manufacturer, serial number, etc. is affixed, and this display sticker is used to fix the locking tongue of the waterproof member. The waterproof member can be securely fixed without increasing the number of members, and the reliable fixing can be performed without forming a large groove for accommodating the waterproof member, which does not hinder the downsizing of the device.
