Abstract:
1. A coaxial connector device comprising: an insulating base provided to be placed on a surface of a circuit board, a signal-joining contacting conductor fixed to the insulating base with a contact connecting portion for projecting from the insulating base and an signal-connecting portion provided on a portion of the insulating base for facing close the surface of the circuit board to be connected to a signal terminal provided on the circuit board, and a grounding contacting conductor fixed to the insulating base and provided with a cylindrical side wall portion for surrounding the contact connecting portion of the signal-joining contacting conductor along the surface of the circuit board, a plurality of ground-connecting portions provided around the contact connecting portion and the signal-connecting portion of the signal-joining contacting conductor on said portion of the insulating base to be connected to ground-potential terminals provided on the circuit board, and a plurality of connecting portions provided for connecting an annular end of the cylindrical side wall portion and each of the ground-connecting portions, wherein at least one groove is formed between the ground-connecting portion of the grounding contacting conductor and the contact connecting portion of the signal-joining contacting conductor and between the ground-connecting portion of the grounding contacting conductor and the signal-connecting portion of the signal-joining contacting conductor on said portion of the insulating base for surrounding continuously or intermittently the contact connecting portion and the signal-connecting portion of the signal-joining contacting conductor, and wherein at least one of the connecting portions is deformed to be bent away from and to become distant from the signal-joining contacting conductor.
