  • Patent number: 7773958
    Abstract: A key pad assembly and a mobile communication terminal having the same. The key pad assembly comprises: a key pad installed at a front surface of a cover so as to be exposed outwardly; a switching unit arranged at a rear surface of the cover for generating a signal when the key pad is pressed; a signal transmitting unit electrically connected to the switching unit below the switching unit, for transmitting a signal generated from the switching unit; and a supporting plate arranged below the signal transmitting unit and having a guiding portion for inducing the signal transmitting unit to be bent in a direction spaced from a lower surface of the cover, for supporting the signal transmitting unit towards the cover. As the key pad assembly is implemented to be slim, a spatial efficiency of the mobile communication terminal is increased.

  • Patent number: 7539521
    Abstract: A locking mechanism includes at least one spring loaded locking member, a lock release device operatively coupled to the spring loaded locking member, and at least one latching member. The latching member is securely gripped by the spring loaded locking member when the lock release device is in partial frictional contact with the spring loaded locking member under the spring bias of the spring loaded locking member. The latching member is released from the grip of the spring loaded locking member when the lock release device is forced in frictional sliding contact with the spring loaded locking member against the spring bias of the spring loaded locking member.

  • Patent number: 7258579
    Abstract: The present invention relates to an external communication jack for a mobile terminal that prevents damage caused by rotation of a plug inserted therein. The external communication jack comprises a body having an insertion passage for accepting a plug, a terminal mounting part formed on the body for mounting the plug, a connection terminal formed at an outer surface of the terminal mounting part and operatively coupled to circuitry for operating the mobile terminal, and a rotation preventing part formed on at least one of an outer surface of the terminal mounting part and an inner surface of the connection terminal, wherein the rotation preventing part at least partially prevents rotation of the connection terminal with respect to the terminal mounting part.

  • Patent number: 7064288
    Abstract: A keypad for a mobile communication terminal is provided. The keypad includes a sheet having contacts which deflect so as to switch contact point pairs on a printed circuit board on and off. The contacts may be formed as hemispherical domes to facilitate use. The sheet may also include band parts covering the contacts and an insulting sheet having at least one pair of semicircular openings which expose portions of the contacts. The insulating sheet is preferably made of a light-reflecting material/color which disperses light to illuminate keys of the keypad.

  • Patent number: 6909063
    Abstract: A keypad of a mobile communication terminal includes a contact sheet having contacts preferably shaped as hemispherical domes which deflect to turn on/off switch contact point pairs on a printed circuit board. The contact sheet further includes band parts covering the domes and an insulating sheet having at least one pair of semicircular openings for exposing portions of the domes. The insulating sheet is preferably made of a light-reflecting material/color which disperses light to illuminate keys of the keypad.
