Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rechargeable electronic device, such as a portable radio, that includes a rechargeable battery.

Conventionally, there have been devices of this type, such as radios shown in FIGS. 1 and 2.

In the figure, 1 is a lid body that opens and closes the entrance 3 of the radio main body 2, 4 is a battery pack to be charged housed in the radio main body case 2, and 5 is a battery pack attached to the lid 1 side. 6 is a wiring board attached to the lid 1 side; 7 is a power supply terminal body for supplying power from the battery pack 4 to the board 6; 8 is a power supply terminal for charging the battery pack 4; 9 is a waterproof packing placed between the lid 1 and the radio body case 2; 10 is a waterproof ring between the power supply terminal 7 and the body case 2;
11 is an O-ring for waterproofing between the charging terminal body 8 and the main body case 2, 12 is a connecting wire for electrically connecting between the power supply terminal body 7 and the wiring board 6, and 13 is for charging. This is a connection line that connects the terminal 8 and the wiring board 6. In the above configuration, since the power supply terminal body 7 and the charging terminal body 8 are attached to the radio device main body case 2 side, the connection wires 12 and 13 are connected between the radio device main body case 2 side and the lid body 1 side. The disadvantage was that the wiring work was time-consuming.

Furthermore, during maintenance and inspection, the connecting wires 12 and 13 may get caught or crushed and break when the radio device main body case 2 and the lid body 1 are separated and reassembled. This invention was made to eliminate the drawbacks of the above-mentioned secondary devices, and by fixing the power supply terminal body and the charging terminal body to the lid side, the connection between the main body case side and the lid body side is improved. The purpose of the present invention is to provide a rechargeable electronic device that not only simplifies assembly work by eliminating the need to route connecting wires to the ground, but also facilitates maintenance and inspection, and can be used in all weather conditions with a simple configuration.

An embodiment of the present invention will be described below with reference to the drawings.

Figures 3 and 4 show an example of a portable radio to which the rechargeable electronic device according to the present invention is applied, and the same parts as in Figures 1 and 2 are given the same numbers for detailed explanation. omitted.

In the figure, reference numeral 14 denotes a power supply terminal body formed, for example, in the shape of a pin, which projects from a boss portion 15 formed on the inner surface of the lid body 1, and its tip is connected to the state in which the lid body 1 is attached. It penetrates through the insertion hole 16 formed in the partition wall 2a on the side of the main body case 2 and comes into contact with the terminal portion of the battery pack 4 to be charged. Packing 19 is delivered to Europe.

Reference numeral 17 denotes a charging terminal body connected to an external power source, and is held on the lid 1 side via the wiring board 6. When the lid 1 is attached, an open row 8 formed on the outer wall of the main body case
It is exposed through the

Further, the charging terminal body 17 is fitted with a waterproof packing having a flared end that closes the closing opening 18 from the inner surface. As is clear from the above Yokosari, charging terminal body 1
7 and the power supply terminal body 14 are respectively attached to the lid 1 side, there is no need to route connection wires between the main body case 2 side and the lid 1 side as in the conventional case, making assembly easier, and the above-mentioned Maintenance and inspection can be easily performed by eliminating connecting wires.

By the way, in the case of a portable radio device, it is necessary to provide all-weather type, that is, to provide liquid-tightness between the terminal bodies 14, 17 and the main body case 2 with a simple structure. For this reason, various waterproof structures can be adopted, but in this embodiment, a cylindrical elastic material that contacts the inner wall of the insertion hole 16 is attached to the power supply terminal body 14 as a waterproof packing 19, and the main body case 16 is
Since the charging terminal body 17 is attached to the charging terminal body 17 as the waterproof packing 20, an elastic material having a flared tip that closes the opening 18 from the inside can provide the following effects.

In other words, when the lid 1 is attached to the main body case 2, the tapered waterproof packing 20 is elastically deformed and tightly attached to the inner surface of the main body case 2 like a suction cup, so that the charging terminal body 17 and the main body case Since the cylindrical waterproof packing 19 comes into contact with the inner wall of the insertion hole 16, the position of the lid 1 and the main case 2 due to variations in dimensions when the lid 1 is attached is ensured. It is possible to reliably provide liquid tightness between the power supply terminal body 14 and the main body case 2 without being affected by displacement.

In addition, although the above embodiment describes a portable radio device, the present invention is not limited to this, and the same effects as in the above embodiment can be obtained in an electronic device having a battery pack to be charged.

As described above, according to the present invention, since the charging terminal body and the power supply terminal body are attached to the lid body side that holds the wiring board, there is no need for conventional connection wires, and the assembly can be centrally managed. This has the effect of reducing work time.

In addition, since there are no connection wires inside the main body case, maintainability is greatly improved, and the cylindrical waterproof packing and the flared waterproof packing are used as power supply terminals and charging terminals, respectively. By providing the body, it is possible to prevent water droplets from entering the main body case through these terminal bodies, and therefore, a highly accurate waterproof function can be provided.
