Description

Wired / wireless charger {A CHARGER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charger, and in particular, charging by a wired charging method through contact between a charging terminal and a battery electrode terminal, and a contactless charging method by magnetic coupling between coils may be simultaneously or selectively performed in one charger. The present invention relates to a wired / wireless charger that is suitable for enabling the charging function and the terminal mounting function to be adjusted at the same time while adjusting the mounting angle.

Generally, a communication terminal is used by being supplied with battery power, and a battery of the communication terminal is supplied with a charging power by a charger.

The charger has been widely used as a wired charging method that supplies charging current through the connection between the charging terminal and the battery electrode terminal on the battery.

However, in the case of the wired charging method as described above, there is a problem that the charging terminal protrudes to the outside and is not good in appearance, and the charging terminal is contaminated with foreign substances and the contact state is poor. In addition, There has been a problem that the charging energy can be easily lost when exposed to moisture. To solve this problem, recently, a charger using a non-contact charging method has been spreading.

The charger using the non-contact charging method is a method of supplying power wirelessly by self-coupling between coils, including a scheme of supplying power by magnetic induction and a scheme of supplying power by magnetic resonance.

The non-contact charging method by the magnetic induction method is disclosed in, for example, Korean Patent Laid-Open Publication No. 10-2008-0032519 (published on Apr. 15, 2008) And a charging method ", a voltage pulse is applied to the primary coil to induce an induced electromotive force by magnetic induction in the secondary coil, and the induced electromotive force induced in the secondary coil causes a battery built in the communication terminal Power supply system.
