A charging apparatus for a mobile device is provided. The apparatus includes a terminal casing and a charging mount. A pattern electrode part has concentric electrode patterns. A first magnet is provided underneath the pattern electrode part, and a second magnet having multiple magnet elements is disposed around the pattern electrode part. The charging mount has a pin terminal part which comes into contact with the pattern electrode part. A third magnet being magnetically coupled with the first magnet is provided underneath the pin terminal part. A fourth magnet being magnetically coupled with the second magnet is provided around the pin terminal part.

Charging apparatus for mobile device

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.

Provided are a double contact point switch and a magnetic connector having the same. The double contact point switch includes: a pin part; an additional terminal part; and an elastic part applying elastic force to the pin part, wherein the pin part includes a front contact point and a rear contact point, the pin part moves rearward when external force is applied to the front contact point of the pin part and again moves forward when the external force of the front contact point disappears, by the elastic part, and the rear contact point contacts the additional terminal part when the pin part moves rearward. As a result of this configuration, it is possible to confirm whether or not a contact of a magnetic connector was made without installing a separate signal terminal in the magnetic connector.
