1. A charging system having a circuit for delaying power supply, the charging system comprising:
- an electronic device having a pattern electrode concentrically formed thereon and having a magnet of the electronic device; and
a charging apparatus having a plurality of pin terminals formed therein and having a magnet of the charging apparatus,wherein the magnet of the electronic device and the magnet of the charging apparatus are magnetically coupled to each other to thereby contact the pattern electrode and the plurality of pin terminals,the plurality of pin terminal includes a Vcc power terminal, a GND ground power terminal, and a D signal terminal,the pattern electrode includes a Vcc electrode and a GND electrode,the GND electrode of the pattern electrode is formed of one electrode which is simultaneously in contact with the GND ground power terminal and the D signal terminal,the charging apparatus includes the circuit for delaying power supply,the circuit for delaying power supply includes a transistor and a capacitor, andthe circuit for delaying power supply blocks the power supply to the Vcc power terminal in the case in which the GND ground power terminal and the D signal terminal are not simultaneously in contact with the GND electrode and releases the blocking of the power supply to the Vcc power terminal because an operation of the transistor is changed and a charging state of the capacitor is changed in the case in which the GND ground power terminal and the D signal terminal are simultaneously in contact with the GND electrode.

Abstract
Provided is a charging system having a circuit for delaying power supply, and more particularly, a charging system having a circuit for delaying power supply installed on a side of a power supply apparatus, wherein the circuit for delaying power supply prevents a spark from being generated when an electronic device and the power supply apparatus are connected to each other.
The circuit for delaying power supply blocks the power supply to the Vcc power terminal in the case in which the GND ground power terminal and the D signal terminal are not in an electrically shorted state and releases the blocking of the power supply to the Vcc power terminal because an operation of the transistor is changed and a charging state of the capacitor is changed in the case in which the GND ground power terminal and the D signal terminal become the electrically shorted state.
