Antenna attachment structure of a case

An antenna attachment structure comprising:

• a conductive member which is provided to one of an antenna attachment section and a case;
• a spring connector which is provided on a circuit board in said case and has a plunger which elastically contacts said conductive member;
• a through-hole which is provided in a section of said conductive member which said plunger elastically contacts, the through-hole having a diameter which is narrower than a tip face of said plunger;
• a second spring connector which has a second plunger, one end of the second plunger passing through said through-hole and directly contacting said plunger and being elastically forced in the direction of its other end;
• and
• a coaxial connector containing section which is provided at the other end of said second plunger of said second spring connector for receiving a coaxial connector;
• wherein
• when said coaxial conductor has been inserted, a center conductor of said coaxial connector forcibly moves said second plunger so as to directly contact said plunger, thereby separating said plunger from said conductive member.

An antenna attachment structure of a case comprising:

• a case having a circuit board therein and comprising an antenna attachment hole for receiving an attachment section of a first antenna;
• a spring connector which is provided on said circuit board and has a first plunger, elasticity being applied to the plunger so that said first plunger protrudes in a direction which is substantially parallel to a direction in which a connector for connecting a second antenna is inserted into said case and wherein said first plunger intersects the insertion direction of said attachment section into said case;
• and
• a conductive member which is provided in said attachment section of said first antenna and is electrically connected to a base of said first antenna;
• said plunger elastically touching said conductive member when said attachment section is inserted into said antenna attachment hole while said conductive member is facing said plunger.

An antenna attachment structure comprising:

• a conductive member which is provided to one of an antenna attachment section of a first antenna and a case;
• a first spring connector which is provided on a circuit board in said case and has a first plunger which elastically contacts said conductive member;
• a through-hole which is provided in a section of said conductive member which said first plunger elastically contacts, the through-hole having a diameter which is narrower than a tip face of said first plunger;
• a second spring connector which has a second plunger, a first end of the second plunger being configured to pass through said through-hole and directly contact said first plunger, said second plunger being elastically forced in a direction away from said first plunger;
• and
• a coaxial connector containing section which is provided at the other end of said second plunger of said second spring connector for receiving a coaxial connector for connecting a second antenna;
• wherein
• when said coaxial connector has been inserted, a center conductor of said coaxial connector forcibly moves said second plunger so as to directly contact said first plunger, thereby separating said first plunger from said conductive member.
