Abstract
A coaxial connecting device is provided for making an electrical connection between a coaxial cable and a device under test. A coaxial connecting device electrically connects a coaxial cable to a signal pad and a ground pad. The coaxial contractor of the present invention includes a signal pin for electrically connecting a signal conductor of the coaxial cable to the signal pad; a ground connector for electrically connecting a ground conductor of the coaxial cable to the ground pad; a cylindrical guide tube surrounding the ground conductor for elastically contacting the ground connector while maintaining a predetermined distance with the signal pin; and a dielectric member surrounding a part of the signal pin for electrically isolating the cylindrical guide tube and the signal pin from each other and coaxially maintaining the guide tube and the signal pin. The coaxial connecting device of the present invention minimizes a contact path between the ground conductor of a coaxial cable and a ground pad and provides impedance matched coaxial signal transmission link, resulting in improvement of frequency characteristics.
