Title:
TELESCOPIC ANTENNA
Document Type and Number:
Japanese Patent JP3447453
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To allow the user to sufficiently obtain a sense of a clicked contact for the recognition of a well-fitting by adopting a contact between metallic parts for a fitting contact of the antenna extraction when a whip antenna in a contained state is extracted and extended telescopically.
SOLUTION: A metallic stopper 34 at a lower end and a metallic wire 31 of a whip antenna 22 operated telescopically are contacted electrically, but a metallic pipe 35 at an upper end and the metallic wire 31 are not electrically connected. When the antenna is extended, the whip antenna 22 is fitted and fixed to a metallic holder 37 and a helical coil 21 and the metallic wire 31 are capacitively coupled. In this case, the metallic holder 37 and the metallic wire 31 are fitted to each other as if to be a unified metallic body. When the antenna is contained, the whip antenna 22 except its knob 33 is entirely contained in the inside of a case 12 and the metallic pipe 35 and the metallic holder 37 are fitted and fixed with each other. In this case, since the metallic wire 31 and the helical coil 21 are arranged at a prescribed interval, the coupling is decoupled.
