In the conventional power supply method, however, one AC adapter is required for one device. Therefore, even if a plurality of devices have the same DC power supply voltage, the number of AC adapters required is the same as the number of devices. As a result, there is a problem that the installation space increases and the overall price increases. In particular, when the current consumption of the device is several tens of mA, the output current of the AC adapter is generally several hundred mA, so that there is a problem that it is uneconomical. The present invention has been made to solve the above-described conventional problems, and has been made in consideration of the following.
An object of the present invention is to provide a power distribution connector that can simultaneously supply power to a plurality of devices with one AC adapter, and can reduce installation space and reduce costs.
