PUSH-ON PUSH-OFF AUTO ANTENNA FOR THE HANDY PHONE

摘要

PURPOSE: A push type automatic extendable antenna for a portable phone is provided to reduce an outer size of a portable phone by pushing a tip portion of an antenna with one finger and making the antenna being extended up by a spring force. CONSTITUTION: A push type automatic extendable antenna is installed on a side of a portable phone to be extended and retracted. The push type automatic extendable antenna is formed of a conductive material of a tube shape. An antenna bar(210) includes retaining rings(211,213) on an upper part and a lower part thereof to smoothly retract and extend the antenna by supporting springs(221,223). An upper and lower guide(230) permits an extending and retracting to be performed by turns when the upper part of the antenna bar(210) is pressed. A rotational latch body(240) and outer bodies(250,260) are inserted into the antenna bar(210). An upper part spring(221) is installed on an upper end of the antenna bar(210) to transfer a power to the rotational latch part(240) and acts as a shock absorber when the antenna is extended up. An extending spring(223) has a motive power so as for the antenna bar to be extended.
