Patent ID: 7648394

Claim:
An electrical coaxial connector comprising; a body made of insulator to be put on a circuit board, a signal-joining contacting conductor held by the body and provided with a signal-joining terminal portion to be connected to a signal terminal provided on the circuit board, and a grounding contacting conductor formed into a cylindrical shape and held also by the body for surrounding the signal-joining contacting conductor on the circuit board, said grounding contacting conductor having an upper ring-shaped end and a lower ring-shaped end, the lower ring-shaped end being closer to the circuit board than the upper ring-shaped end, the lower and upper ring-shaped ends being opposite to each other in a direction perpendicular to the circuit board, wherein the grounding contacting conductor further includes an arm portion extending upwardly from an edge of the upper ring-shaped end of the grounding contacting conductor and downwardly toward the circuit board, a horizontal grounding terminal portion extended inwardly and toward the grounding contacting conductor is formed at a lower end of the arm portion to be soldered to a ground-potential terminal provided on the circuit board, and each of the grounding contacting conductor and the arm portion is made of resilient conductive material, wherein a plurality of arm portions are provided on the upper ring-shaped end of the grounding contacting conductor.
