Rod antenna mounting mechanism of radio terminal equipment

A rod antenna mounting mechanism for extensibly and stowably mounting a rod antenna to a casing of a radio terminal equipment, said rod antenna including an extended small-diameter rod section, first and second large-diameter rod sections formed continuous to both ends of said small-diameter rod section, a cap formed at the end of said first large-diameter rod section, and a stopper formed at the end of said second large-diameter rod section, said rod antenna mounting mechanism comprising:

• rod holder means slidably installed to said rod antenna for holding said rod antenna to said casing, said rod holder means having a pipe-like portion provided with a slit formed in a longitudinal direction to permit elastic expansion thereof and a large-diameter portion exposed out of said casing when said rod antenna is held in said casing, said large-diameter portion of said rod holder means being insulated;
• an elastically deformable feeder plate connected to a radio circuit housed inside of the casing;
• and
• means for pressing said pipe-like portion of said rod holder means into contact with said feeder plate, said pipe-like portion and said second large-diameter rod section are electrically conductive, and said small-diameter rod section, said first large-diameter rod section and said cap are covered with an insulator, when said rod antenna is pushed into said casing and said first large diameter rod section contacts an inside surface of said pipe-like portion, said pipe-like portion elastically expands to receive said first large-diameter rod section press fitted into said pipe-like portion, and when said rod antenna is pulled out of said casing and said second large diameter rod section contacts the inside of said pipe-like portion, said pipe-like portion elastically expands to receive said second large-diameter rod section press fitted into said pipe-like portion.
