Description

The present invention relates to a charging device that supplies electric power for charging to a secondary battery built in an electric / electronic device, such as a rechargeable microphone device.
In particular, the present invention relates to an improvement in a charging device that can supply charging power to two or more types of charging target devices that differ in the size of the device main body of the charging target device, the position and shape of the input terminal for charging, and the like.

In a rechargeable microphone device that is a device to be charged with a built-in secondary battery, it is necessary to supply power from the outside in order to supplement the power of the secondary battery.
As a charging device for a rechargeable microphone device that supplies electric power from the outside and replenishes power to a built-in secondary battery, those disclosed in the following published patent publications are known.

  No. 7-15264

The charging stand 2 which is a charging device disclosed in Japanese Utility Model Publication No. 7-15264 performs charging in a state where the rechargeable microphone 1 is housed and fixed by the cup portion 2a, and at the position of the rechargeable microphone 1 side. The charging terminals 1b and 1c are configured to be connected to the connection pin 4 on the charging stand 2 side.
The charging stand 2 disclosed in the publication is configured to supply charging power to only one type of rechargeable microphone device 1.

That is, the diameter of the cylindrical portion of the main body of the rechargeable microphone 1 is slightly smaller than the diameter of the cup portion 2 a of the charging stand 2.
When the rechargeable microphone 1 is fitted to the charging stand 2, the rechargeable microphone 1 is almost positioned and fixed by the cup portion 2 a of the charging stand 2.

In addition, when the rechargeable microphone 1 is fixed inside the charging stand 2, the circular charging terminal 1 c disposed at the bottom of the rechargeable microphone 1 and the donut-shaped charging terminal 1 b surrounding the charging terminal 1 c are respectively connected to the connection pins 4. The charging power is supplied from the charging stand 2 to the rechargeable microphone 1.
Therefore, in the device having such a configuration, when the rechargeable microphone 1 is supplied with charging power from the charging stand 2, the rechargeable microphone 1 is positioned with respect to the charging stand 2, and the charging terminals 1b and 1c are charged. It contacts the connection pin 4 on the stand 2 side, becomes conductive, enters a chargeable connection state, and does not cause any problems.

However, in the above-described configuration, when the diameter of the main body of the rechargeable microphone 1 is different, the positions of the charging terminals 1b and 1c and the shapes of the charging terminals 1b and 1c correspond to the charging terminals of the charging device. If charging power is not supplied as a result, and if the arrangement of the positive and negative electrodes of the charging terminals 1b and 1c does not correspond to the electrodes of the charging device, the charging stand 2 supplies the charging power. Even if it can be output, charging power can be supplied only to the rechargeable microphone 1 of only one type, and charging power cannot be supplied to other different types of rechargeable microphones.
In other words, rechargeable microphone devices that are currently on the market are very similar in appearance and shape, but the size of the device itself, the shape and location of the terminals to be charged, There is no standardization regarding the polarity of charging terminals.

This is because the diameter of the cylinder part that is planned and manufactured arbitrarily by each manufacturer, or the design is arbitrarily determined according to the demand of the user, This is due to the fact that there is no standardization or commonality with respect to the arrangement position, shape, and polarity of the terminals to be charged.
For rechargeable microphone devices in which the diameter of the microphone device main body, the position and shape of the terminal to be charged, and the arrangement of the positive and negative electrodes are different from each other, of course, only one type of charging device can be used for charging power. It is impossible to supply.

In particular, in a charging device in which the positive and negative electrodes do not correspond to the terminal to be charged that receives charging power in the rechargeable microphone device and the polarity is reversed, the rechargeable microphone device is charged. Will not be performed, and the rechargeable microphone device will be damaged.
On the other hand, in order to charge a plurality of rechargeable microphone devices having different diameters of the device main body, arrangement positions / shapes of terminals to be charged, and arrangements of positive and negative electrodes, types of the plurality of different rechargeable microphone devices It is conceivable to prepare a charging device corresponding to each of the numbers and supply charging power using the corresponding charging device.

However, in the case where a plurality of charging devices are prepared and selectively used corresponding to a plurality of rechargeable microphone devices, the number of charging devices prepared and used is the same as the number of rechargeable microphone devices. Problem arises.
Further, there is a problem that the charging terminal and the object to be charged do not correspond to each other because the charging power is not supplied at all, and the practicality is low.

For such a problem, by interposing an adapter between the charging device and the charging target device not compatible with the charging device, it becomes possible to supply charging power to the charging target device not compatible with the charging device. .
However, if the charging target device is used in an environment where the amount of light is insufficient, such as a karaoke microphone, is an adapter attached to the charging device? Whether the adapter is compatible with the target device to be charged when the adapter is attached to the charging device? Therefore, there is a new problem that it cannot be easily determined and lacks practicality.

In particular, when the usage environment is under an insufficient amount of light, the problem becomes even more serious when the device to be charged that matches the charging device is visually confirmed.
The present invention has been made in view of the above-described circumstances, and an adapter is interposed between the charging device and the charging target device when supplying charging power to the charging target device that is not suitable for a specific charging device. When power is supplied, it is easy to determine whether an adapter is attached to the charging device, and to which charging target device the adapter fits when the adapter is attached to the charging device. The present invention provides a charging device that can be used for the following.
