  "abstract": "A mobile terminal includes a display unit, a front case configured to be combined with the display unit using a front side of the front case, a main board configured to be combined with a rear side of the front case, a rear case configured to be combined with a rear side of the main board, a boss in which a internal screw thread formed on both a left side and a right side of the front case and the internal screw thread heading a rear side is formed, a connection hole formed on a position corresponding to the internal screw thread of the rear case, a screw configured to be connected with the internal screw thread in a manner of passing through the connection hole, a boss bump configured to be positioned at an outer circumstance of the boss and a boss accommodation part configured to be formed on both a left side and a right side of the main board and correspond to a shape of the boss and a shape of the boss bump. It is able to reduce thickness of the mobile terminal by omitting a frame. And, it is able to prevent the case from making a gap in a horizontal direction via a stable connection structure. Moreover, it is also able to prevent the front case and the rear case from being separated from each other via the stable connection structure.",
  "claims": [
    "1. A mobile terminal comprising: a display unit; a front case having an opening formed there through, wherein the front case is configured to permit the display unit to be viewed through the opening from a front side of the front case; a main board configured to be combined with a rear side of the front case; a rear case configured to be combined with a rear side of the main board; a boss projecting inward from an edge portion of the front case, the boss having a rear-facing opening formed therein with an internal screw thread on an inner surface of the rear-facing opening, and the rear case including a connection hole formed to align with the rear-facing opening in the boss; a screw configured to pass through the connection hole and engage the internal screw thread; and a boss bump projecting laterally from a side surface of the boss, wherein the main board includes a boss accommodation part comprising: a boss groove accommodating the boss; and a bump groove having a recessed shape in the boss groove and accommodating the boss bump, and wherein the positioning of the boss groove together with the boss bump fixes the edge portion of the front case to the main board in an outward direction.",
    "2. The mobile terminal of claim 1, wherein the boss bump projects diagonally from the side surface of the boss relative to a horizontal line perpendicular to the edge portion of the front case.",
    "3. The mobile terminal of claim 1, wherein the boss comprises a plurality of boss bumps projecting from the side surface of the boss.",
    "4. The mobile terminal of claim 1, wherein the boss bump has a rear surface and the boss has a rear surface, and wherein the rear surface of the boss is further rearward than the rear surface of the boss bump.",
    "5. The mobile terminal of claim 1, wherein the boss is configured such that a rear surface of the boss projects further in a rearward direction than a rear surface of the main board and a rear surface of the boss bump.",
    "6. The mobile terminal of claim 1, wherein the boss bump has a curved or polygonal shape.",
    "7. The mobile terminal of claim 1, wherein the front case comprises a plurality of bosses projecting inward from an edge portion thereof, and at least one connection hook projecting inward from the edge portion of the front case and contacting the rear surface of the main board; and wherein the rear case comprises at least one connection groove, each connection groove aligning with and configured to receive a corresponding connection hook.",
    "8. The mobile terminal of claim 1, wherein the main board is configured to contact a rear side of the display unit via the opening formed at the center of the front case."

  "description_excerpt": "This application claims the benefit of the Korean Patent Application No. 10-2014-0099707, filed on Aug. 4, 2014, which is hereby incorporated by reference as if fully set forth herein.\n\nField of the Invention The present invention relates to a frameless terminal from which a frame supporting a rear side of a display unit is omitted. Discussion of the Related Art Terminals may be generally classified as mobile/portable terminals or stationary terminals according to their mobility. Mobile terminals may also be classified as handheld terminals or vehicle mounted terminals according to whether or not a user can directly carry the terminal. Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.\n\nAs functions of a terminal are diversifying, the terminal is implemented as a form of a multimedia player equipped with such complex functions as capturing a picture or a video, playing music or a video file, gaming, broadcast reception and the like. Thickness of a mobile terminal is gradually getting thinner in order to secure portability of the mobile terminal.",
