&Lt; Description of constitution of multi-outlet according to the present invention &

As shown in FIG. 1 and FIG. 2, the multi-receptacle capable of outputting a Bluetooth speaker according to the present invention comprises: A socket body 100 having a plurality of plug sockets 110 formed therein so as to electrically connect plugs (not shown) of an electrical product to the plug socket 110 (not shown) A power cord 200 electrically connected to the positive (+) (-) connection terminal of the plug socket 110 and provided with a plug 210 at the tip thereof, A main switch 300 for turning on / off the power input to the connection terminal side, individual switches 400 for individually controlling power supply to the plug sockets 110, and a DC power supply for outputting a DC power supply Unit 500 and a Bluetooth speaker unit 600 for wirelessly communicating with the portable terminal via Bluetooth to output an audio signal to the outside. Hereinafter, the respective components constituting the multi-receptacle according to the present invention will be separately described in detail.

First, the socket main body 100 forms the external shape of the multi socket socket product. Here, a plurality of plug sockets 110 are exposed to the outside so that a plug of an electrical product can be connected, and a (+) (-) connection terminal is provided inside the socket. The power cord 200 is electrically connected to the (+) and (-) connection terminals of the plug sockets 110, and a plug 210 is provided at the tip end. The plug 210 of the power cord 200 is connected to a flush-type receptacle or the like to receive external power.

The main switch 300 applies a positive polarity cutoff switch that can shut off all power input to the (+) (-) terminal. This cuts off the positive polarity, This is to maximize the power saving effect by completely blocking the flow.

The individual switches 400 are connected to the branch terminals for supplying power to the positive (+) and negative (-) connection terminals 120 of the respective plug sockets 110, And the power supply to the plug sockets 110 can be individually controlled.

The direct current power supply unit 5000 is accommodated in one side of the socket main body 100 and can convert 220 V AC power inputted from the outside through the power cord 200 into 5 V DC power and output it. And the USB connection port 510. When the portable terminal is connected to the USB connection port 510 through a USB cable (not shown), the 5V DC power source is charged.
