PURPOSE: An antenna device using a hinge spring is provided to allow more liberty in designing an appearance of a mobile phone, reduce a unit cost of an antenna, and maximize a space efficiency because no space is needed for the antenna. CONSTITUTION: A hinge housing(301) is mounted at a center hinge arm of a sub housing, and receives a hinge shaft(302), a hinge cam(303), a conductive member and a hinge spring(305). The hinge shaft(302) has one end(302a) connected to a side hinge arm of the main body housing and the other end(302b). The hinge cam(303) includes a portion(303a), portion(303b) and a protrusion(303d) so as to linearly move in the housing(301). The hinge cam(303) has a through hole(303c) extended along the hinge shaft(302). The conductive member provided between the hinge cam(303) and the hinge spring(305) includes a contact portion(304a) contacting with one portion(305a) of the spring(305) and a central portion(304b) positioned at through holes(303c,302c). The hinge spring(305) is provided between the hinge housing(301) and the conductive member(304). One end(305a) of the hinge spring(305) is maintained to be in contact with the contact portion(304a) and serves to constantly attach the hinge shaft(302) and the hinge cam(303). A pan spring(32) made of a conductive material with elasticity includes two free ends(321,322). |
