Description

Multi outlet with DC converter {Multi consent with a direct current converter}

The present invention relates to a multi-outlet provided with a direct-current converter for easily supplying a DC operating power to a device using a DC power supply by integrally provided with a direct-current converter in a multi-outlet having a plurality of plug insertion ports.

In general, various portable devices such as a portable cassette tape recorder use a DC power source as an operating power source, and typically supply a battery power source as an operating power source. The battery is relatively expensive, and a heavy economic burden is placed on the user when only the battery is used. Therefore, many users of portable devices use a separate DC converter which supplies the battery power to the operating power when the portable device is used while moving, and converts the AC power into DC power in a fixed place such as a home or office. To supply direct current power to portable equipment.

Meanwhile, various fixed structures including homes and offices are provided with outlets for supplying AC power to electrical and electronic products. However, the outlet is inserted into a wall or the like and is fixed, and electrical and electronic products using an AC power source have been used near the wall where the outlet is fixed. In addition, a plurality of electrical and electronic products are driven simultaneously and used, for example, a computer system, a monitor, a printer, and the like must be operated at the same time. Difficult to use due to the small number of plug insertion holes.

Therefore, many users have a multi-outlet having a plurality of plug inlets, and the multi-outlet extends the AC power of the outlet fixed to the wall to supply electrical and electronic products, as well as a plurality of plug inlets of the multi-outlet. By inserting the plug of the electrical and electronic products of the AC power is supplied so that a plurality of electrical and electronic devices can be operated simultaneously.

However, the multi-outlet can only supply AC power to a plurality of electrical and electronic products by extending AC power, and cannot supply DC power. Therefore, when operating portable devices using DC power as operating power, In addition to a multi-outlet, a separate DC converter had to be used. As a result, users had to separately purchase a multi-outlet and a DC converter, which caused a lot of economic burden.

Therefore, an object of the present invention is to integrate a DC converter unit into a multi-outlet having a plurality of plug insertion ports to supply AC power to a plurality of electrical and electronic products as a working power, as well as to use a built-in DC converter. The present invention provides a multi-outlet having a DC converter for supplying a DC operating power to a portable device.

According to the multi-outlet provided with the DC converter of the present invention for achieving the above object, a plurality of electrical and electronic products of which the AC power is applied and the terminal is inserted into the connection hole of the first and second second power connection iron pieces A multi-outlet for supplying alternating current power to electrical and electronic products through a plug, the electrical outlet being electrically connected to the first and second second power connection iron pieces and supplied to the first and second second power connection iron pieces. A DC converter for converting AC power into DC power and supplying DC power as operating power to a portable device is characterized in that it is integrally provided.

And the direct current converter; Step-down transformer for stepping down AC power; A bridge diode for rectifying the step-down AC power supply of the step-down transformer; A capacitor for smoothing the power rectified by the bridge diode and converting the power into a DC power source; And a jack for supplying the smoothed DC power to the operation power through the DC power plug 20 of the portable device to be inserted.
