Abstract: A coil component includes a body including magnetic metal powder and an insulating resin, an insulating substrate embedded in the body, a coil portion disposed on at least one side of the insulating substrate the body, and having a lead-out pattern exposed from one of end surfaces of the body opposing each other, an external insulating layer exposing the lead-out pattern while surrounding the body, and including a magnetic ceramic, and an external electrode disposed on the body, and connected to the lead-out pattern.

Abstract: A rechargeable battery having a compact size and improved strength comprises a case, a battery cell, a circuit board and a covering member. The case has an internal space and an open end. The battery cell is made of a pliable material and is installed within the case, wherein a surface of the battery cell is electrically connected to the circuit board at the open end of the case. The covering member hermetically seals the open end of the case. Accordingly, the battery has a compact size, improved strength and may be manufactured easily.

Abstract: A safety device of a battery including a pressure releasing unit provided at a cell and the battery, in which the pressure releasing unit is configured to release an internal pressure within the cell when the internal pressure of the cell exceeds a predetermined set pressure. Also included is a space member covering the pressure releasing unit and configured to form an empty space around the pressure releasing unit such that when the internal pressure of the cell exceeds the predetermined set pressure, the released internal pressure is released into the empty space formed by the space member.

Abstract: A device and method for coupling a battery to a mobile terminal. The device comprises a main body having a main board on which circuit components are mounted, a battery receiving portion disposed on the main body for receiving the battery, and an input/output connector mounted on a side of the battery receiving portion for supplying electrical power to the main body. A power terminal is disposed on a first side face of the battery for detachably coupling to the input/output connector. The power terminal being arranged to electrically connect to the input/output connector as the power terminal is moved in a longitudinal direction toward the input/output connector. The input/output connector provides an elastic restorative force to the first side face of the battery for maintaining electrical contact between the power terminal and the input/output connector upon a shift in position of the battery within the battery receiving portion.

Abstract: A power connection structure of a mobile terminal, includes: a battery detachably mounted to a battery mounting portion of a mobile terminal body, wherein terminal groups, each including a plurality of terminals, are disposed at a predetermined interval; a plurality of terminal assemblies including a plurality of terminals and mounted corresponding to the predetermined interval so as to respectively contact with the terminal groups of the battery; and a receptacle positioned between the terminal assemblies. Accordingly, a region where constituent elements for power supply are installed is minimized, and a size of the mobile terminal may be reduced.

Abstract: A rechargeable battery with an integrated protection circuit is made to have a high rigidity to withstand an external impact. The rechargeable battery comprises a case having an enclosed internal space for housing a battery cell, a circuit board having the protection circuit, the circuit board electrically connected to the case at a first end, a reinforcing member formed at the first end where the circuit board is connected, and a molding member formed at the first end of the case for encapsulating the circuit board and the reinforcing member.
