[Industrial applications]

 The present invention uses a waterproof case to waterproof electronic devices with built-in charging batteries such as cordless phones and mobile phones, and contacts the secondary circuit of the electromagnetic induction charger and the charging battery terminal in the waterproof case. It is equipped with a terminal to charge an object to be charged. A battery that allows the charging battery for electronic devices such as cordless phones and mobile phones to be charged with the waterproof case still attached. In addition, it allows the operation of cordless phones and mobile phones with the waterproof case attached, which is technically difficult and costly to make electronic devices such as cordless phones and mobile phones waterproof. Things that can be avoided. .

[0002]

[Prior art]

 In the conventional electromagnetic induction charging method, the secondary coil section and secondary circuit section are provided inside electronic devices such as cordless phones and mobile phones, and the waterproofing of electronic devices such as cordless phones and mobile phones is fully achieved. It was difficult to do. Of course, it is impossible to charge the battery with the waterproof case attached, and in order to charge the battery, electronic devices such as cordless phones and mobile phones had to be taken out from the waterproof case. In addition, it has been technically difficult and costly to make electronic devices such as cordless phones and mobile phones waterproof.

[0003]

[Problems to be solved by the device]

 Although there is a waterproof case for waterproofing electronic devices with built-in charging batteries such as cordless phones and mobile phones, the waterproof case must be removed in order to charge the battery. There is currently no waterproof case available. By installing the secondary side device case in which the secondary coil of the electromagnetic induction charger, the secondary circuit, and the terminal that contacts the charging battery terminal are provided at the bottom of the waterproof case, charging is performed with the waterproof case attached. This makes it possible to improve convenience and improve the waterproof performance of electronic devices such as cordless phones and mobile phones.

Further, it is technically difficult and costly to make an electronic device itself having a charging battery such as a cordless phone or a mobile phone built in a waterproof structure, but an electromagnetic induction charging function is required. These problems can be solved by using a waterproof case equipped with.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is provided with the reference numerals shown in the embodiments. In claim 1, the charging base 9 is provided with the primary coil 7 and the primary circuit 8, while the waterproof case is provided. A secondary side device case 4 in which the secondary coil 6, the secondary circuit 5, and the battery terminal block 3 are arranged is provided at the bottom of the device 2. By placing the waterproof case 2 accommodating the electronic device 1 such as a cordless phone or a mobile phone having a built-in charging battery on the charging stand 9, both coil parts come close to each other to form the electromagnetic induction part 11, By the electromagnetic induction action of the electromagnetic induction section 11, electricity is supplied from the charging stand 9 to the charging battery 10 of the object to be charged 1 via the secondary side device case 4 in the waterproof case 2. Is adopted.

[0006]

[Action]

 According to the first aspect, by placing the waterproof case 2 containing the electronic device 1 such as a cordless phone or a mobile phone having a built-in charging battery on the charging stand 9, the coil parts 6 and 7 are brought close to each other. Then, the electromagnetic induction section 11 is formed to generate an electromagnetic induction effect, and the electromagnetic induction section 11 from the commercial power source connected to the charging stand 9 side is used as a power connection section for the secondary side device case in the waterproof case 2. It is possible to supply electricity to the secondary coil provided in No. 4 in a non-contact manner and further charge the charging battery 10 of the object to be charged 1.

According to the third aspect, the charging stand 9, the waterproof case 2, and the secondary side device case 4 are both formed of an insulating material of resin material so that they serve as an insulating cover and a waterproof function. Therefore, even if a conductive liquid adheres to the upper surface of the charging base 9 or the lower surface of the waterproof case 2, there is no possibility of damaging the device or causing electric leakage.

Further, since the primary coil portion 7 and the secondary coil portion 6 are arranged coaxially with each other, the top surface of the charging stand 9 and the bottom surface of the waterproof case 2 containing the object to be charged 1 facing the top surface of the charging stand 9 are opposed to each other. And can be formed flat, and the object to be charged 1 can be stably placed on the charging base 9.

[0009]

【Example】

 FIG. 1 shows an embodiment of the present invention, and shows a cordless telephone or a portable telephone as an object to be charged 1. The telephone 1 is housed in a waterproof case 2. A secondary-side device case 4 is attached to the bottom of the waterproof case 2, and a secondary coil, a secondary circuit, and a battery terminal block are arranged in the secondary-side device case 4.

A primary coil and a primary circuit are provided as a primary device in the charging stand 9 on which the telephone set housed in the waterproof case is placed.

The waterproof case 2, the charging stand 9 and the secondary side device case 4 are made of an insulating material such as a resin material, and serve as an insulating cover and a waterproof function.

By placing the telephone 1 housed in the waterproof case 2 on the charging stand 9, the primary coil section 7 in the charging stand 9 and the secondary coil section 6 in the secondary side device case 4 are brought into close proximity. As a result, the electromagnetic induction portion 11 is formed between the coil portions 7 and 6. Therefore, the electricity from the commercial power source supplied to the primary coil section 7 on the charging stand 9 side is conducted to the secondary coil section 6 via the electromagnetic induction section 11, and passes through the secondary circuit 5 and the battery terminal block 3 for charging. Electricity will be supplied to the battery 10.

[0013]

[Effect of device]

 According to claim 1 of the present invention, the power source from the charging stand can be contactlessly connected to the secondary coil in the waterproof case via the electromagnetic induction part, and the battery for charging the object to be charged can be charged. . Therefore, it is possible to charge the battery with the waterproof case attached, which improves convenience and waterproof performance.

Further, it is possible to avoid the technical difficulty and the high cost for making the main body of the electronic device such as the cordless phone or the mobile phone waterproof.

Further, according to claim 3, since the conductive terminals are not exposed at all in the connection terminal portion of the charging stand and the waterproof case accommodating the electronic device such as the cordless phone or the mobile phone, It has excellent moisture and water resistance, and can be used in a wet condition or in a high humidity place. In addition, the top surface of the charging base and the bottom surface of the object to be charged facing the charging surface can be formed flat, and the object to be charged can be stably placed on the charging base.
