20140066138 | Back cover for mobile terminals - A back cover for mobile terminals which protects the rear surface of a mobile terminal having a battery in the rear surface. The back cover includes: a cover body mounted to the rear surface of the mobile terminal; hooks formed on the edge of the cover body and locked to the rear surface of the mobile terminal; a terminal unit provided on a first surface of the cover body at a location corresponding to terminals of the mobile terminal; a pattern electrode unit provided on a second surface of the cover body and electrically connected to the terminal unit, the pattern electrode unit having an electrode that electrically connects the terminals of the mobile terminal to an outside charger; and a magnet placed in the cover body and magnetically connected to the outside charger. | 03-06-2014 |
20130237085 | USB connector for sensing insertion - Provided is a USB connector capable of sensing the insertion of USB devices such as a mobile phone, PDA, MP3 player and the like into the USB connector. The USB connector includes: a fixing body which is shaped as a quadrangle and made of metal material; an insulating member which is inserted and fixed within the fixing body, and one side of which has a power terminal and a data terminal connected to respective lead pins; and a switching pin which is elastically coupled to one side of the insulating member such that the switching pin is insulated from the fixing body, and which senses the insertion of a USB device by being brought into contact with the USB device inserted into the fixing body. | 09-12-2013 |
20120295451 | Magnetic connecting device - The present invention relates to a magnetic connecting device, which is magnetically and electrically coupled to an external device via a communication-type magnetic connector and is configured to transfer operating power to the external device after checking the external device using communication when the external device is coupled to the connecting device, thus ensuring convenience and safety in use. The magnetic connecting device includes a plurality of power terminals magnetically coupled to a connector of an external device and configured to transfer power to the external device, and at least one communication terminal arranged adjacent to the plurality of power terminals and configured to come into contact with the connector of the external device and to transmit or receive data when the external device is coupled. | 11-22-2012 |
20120206090 | Charging device using magnets - A charging device using magnets is disclosed. The charging device using magnets includes a sleeve and a charging pad. The sleeve includes a connector connected to the charging terminal of a mobile terminal, and a plurality of magnetic terminals connected to the connector. The charging pad includes magnetic electrodes which magnetically come into contact with the respective magnetic terminals of the sleeve, and supplies charging power to the magnetic terminals using the magnetic electrodes. The magnetic electrodes of the charging pad are configured such that magnetic forces are attenuated due to magnetic fields of coils or such that repulsive forces are generated between the magnetic electrodes of the charging pad and the magnetic terminals of the sleeve which come into contact with the magnetic electrodes. | 08-16-2012 |
20110273912 | Switching mode power supply - A switching mode power supply (SMPS) including: a first state transform unit, including: a second photo diode; and a second photo transistor included between an AC power input unit and the pulse width modulation control unit to form a photo coupler with the second photo diode, and a second state transform unit, including: a comparator connected to a secondary winding of the main transformer to apply the output voltage and reference voltage to an inverting terminal and a noninverting terminal, and compare the output voltage with the reference voltage and output the voltage through an output terminal. | 11-10-2011 |
