Description

APPARATUS FOR CONNECTING POWER SOURCE

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power connection apparatus for connecting a power outlet to a power outlet, and more particularly to a power plug having a significantly improved amount of power.

2. Description of the Related Art In recent years, there has been an increase in the use of a smart power connection device that is inserted between an outlet and a power plug and incorporates a wireless communication circuit, a load sensing circuit, and a power control circuit. These power connections emit heat due to the current load on the built-in circuitry, which in turn increases the overall temperature of the power connection and is a risk factor for electrical safety accidents such as fire. In case of exceeding 30% of rated current capacity for 1 hour, the difference between the temperature of power connection and outside temperature shall be kept below 45 ℃. However, most of the conventional power connection devices are limited to about 10A in terms of the certification standard due to space constraints and the like. Therefore, in the case of most of the existing power connecting devices, such as air conditioners, electric heaters, etc. connected to heavy electronic devices, the risk of safety accidents frequently occurs due to restriction of the amount of electric power.
