Folder type mobile communication terminal
View Patent ↗A folder type mobile communication terminal includes a first housing and a second housing hingedly connected to the first housing. The second housing includes a second knuckle on the rotation axis where the second knuckle defines an opening hole inside thereof for insertion of a connection cable, a second hinge aperture formed in the axial direction of the rotation axis to allow the connection cable to insert therethrough, a projecting part at one end, and a structure at the opposite end which allows installation of a hinge spring assembly. The first housing includes first knuckles formed at both ends, where the first knuckles define a first hinge aperture that is directed to the direction of the second hinge aperture, and a first slot formed in the bottom of one of the first knuckles to enable the connection cable to insert therethrough.
1. A folder type mobile communication terminal comprising:
a first housing; and
a second housing hingedly connected to said first housing,
wherein said second housing comprises, on a surface facing said first housing, a second knuckle defining a second hinge aperture serving as a rotation axis, and an opening hole in a middle of an inner sidewall of said second knuckle, and leading a FPC (Flexible Printed Circuitry) into said second hinge aperture, and a projecting part being formed at one end of said second knuckle to be rotatably inserted into an inner periphery of said first hinge aperture,
wherein said first housing comprises first knuckles at both ends defining a first hinge aperture that is directed to the direction of said second hinge aperture for connection to the second knuckle, and a first slot extending from a bottom of one of the first knuckles toward a front surface of the first housing, and
wherein, said projecting part and a FPC passage route of the second hinge aperture, have a second slot serving as a passageway for a FPC's connection part, said second slot allowing said FPC's connection part that is wider than the diameter of said second hinge aperture to pass there through, and
wherein said second knuckle has a subsidiary guide slot on the opposite parts of said projecting part and the FPC passage route of the second hinge aperture, serving as a guideway for said FPC's connection part and preventing said FPC's connection part from being damaged during passing said second hinge aperture.
2. The folder type mobile communication terminal as set forth in claim 1 , wherein the depth of insertion of the projecting part formed at one end of said second knuckle into said first hinge aperture is so sized that said first and second housings are assembled with ease and do not break off during openings and closings thereof.
