Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure and waterproof packing of a waterproof portable radio device such as a cordless phone handset or a mobile phone.

[0002]

2. Description of the Related Art In conventional cordless telephone handsets or mobile telephones, since they are sometimes used outdoors, packing is often interposed between the fitting portions of the upper and lower cases to make them waterproof. In addition, when the case is provided with an opening for connecting an external power source or an opening for connecting other equipment such as a headset, when the openings are not used, each opening is provided with a separate closure. Press-fitting the cover is performed.

[0003]

In the conventional waterproof structure described above, the packing provided in the fitting portions of the upper and lower cases and the cover for closing the opening for external power source connection or headset connection are provided. Due to the fact that they are separate, for example, when there are two openings to be closed, three waterproof rubber members are required, and it is necessary to prepare them separately and mold them separately. In addition to this, a plurality of members must be individually mounted, which complicates the assembling work, and has a drawback that the closing cover is temporarily removed or is easily lost due to falling off.

Therefore, an object of the present invention is to provide a waterproof portable radio equipment capable of reducing the cost of molding equipment, the rubber member itself, and the cost of assembling work with a simple structure which does not require individual parts. Another object of the present invention is to provide a packing for a portable wireless device, and another object of the invention is to provide a waterproof portable wireless device capable of reliably preventing loss of the closing cover.

[0005]

In order to achieve the above-mentioned object, the present invention uses a waterproof packing in which a waterproof annular main body of a fitting portion in both upper and lower cases and an opening closing cover are integrally molded, The annular main body is interposed between the fitting portions of both cases, and the closing cover can be press-fitted into the opening for connecting the device.

[0006]

The ring-shaped main body of the waterproof packing in which the closing cover is molded in the same body is interposed between the fitting portions of the upper and lower cases to keep the fitting portions of the upper and lower cases liquid-tight, and the closing cover is opened. The unused opening is closed in a liquid-tight state by being press-fitted into the portion, and the closing cover is integrally connected to the main part of the waterproof packing, so there is no risk of loss due to falling off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in FIGS. 1 to 3 in which the present invention is applied to a cordless telephone will be described in detail below.

As a wireless device to which the present invention is applied, for example, as shown in FIG. 1, an upper case 1a and a lower case 1b are fitted in an anastomosis state with a waterproof packing 2 interposed therebetween. A long and narrow rectangular parallelepiped plastic case 1 suitable for grasping is formed, and a transmitter section 3 and a receiver section 4 are separately provided near both ends of the case 1, and in the vicinity of the center for dial and In addition to providing the operation unit 6 having the pushbuttons 5 and 5 for the function, the antenna 7 is provided at one end portion on the side of the upper case 1a in a projecting state, and the electrical equipment necessary for the wireless device is equipped, and the upper case 1a is provided. The side and end portions thereof are provided with circular openings 8 and 8 having relatively small diameters, and inside the openings 8 and 8, a connector for external power supply connection and a connector for headset connection, respectively. Both the provided not shown), to further adopt type cordless telephone which is adapted to press-fit the respective closure cover 9 and 9 in the opening 8, 8.

As a special configuration of the present invention for the above-mentioned type of telephone, for example, as shown in detail in FIGS.
As the waterproof packing 2, the annular main body is outwardly connected to the connecting portions 10 and 10 and the closing covers 9 and 9 are integrally formed in a protruding state by molding with silicone rubber to form an opening. Before closing the upper case 1a and the lower case 1b, the ring-shaped main body of the waterproof packing 2 is sandwiched between the upper and lower cases 1a and 1b before the fitting of the upper case 1a and the lower case 1b. After interposing,
While bending the connecting portion 12, the closing covers 9 and 9 are opened to the opening portion 8,
Press into No. 8.

Although the above-mentioned embodiment is a case where the present invention is applied to a cordless telephone, the present invention is not limited to a cordless telephone and can naturally be applied to other waterproof portable radio equipment.

[0011]

As described above, the present invention has the following effects. a. A waterproof packing 2 in which an annular main body and an opening closing cover 9 are integrally molded is provided in both upper and lower cases 1 in the annular main body.
The closing cover 9 is provided at the fitting portion with the a and 1b.
Since it is configured to be press-fitted into the opening 8, as compared with the conventional structure in which the main packing body and the closing cover are separate,
Under the condition that the number of parts is reduced by a simple structure, the storage and inventory management of parts can be facilitated and the cost of assembling work can be reduced. b. Since the annular main body and the opening closing cover 9 are integrally molded as the waterproof packing 2, the facility cost of the molding die and the like can be low, and the molding work is simple, and therefore the manufacturing cost is remarkably reduced. be able to. c. Since the annular main body and the opening closing cover 9 are integrated as the waterproof packing 2, it is possible to reliably prevent the relatively small closing cover from being lost, and particularly when the closing cover is temporarily removed or dropped. Even if you do, you will not lose it.
