Patent ID: 7262672

Claim:
A connection structure for transmission of high frequency signals, comprising a connector body, which constitutes the outer appearance as well as housing of the connector; an inner conductor installed in said connector, including a first and a second terminals which are placed to face each other; a dielectric which insulates said connector body from said inner conductor and determines impedance of said connector; an extendible pin, which is connected electrically to said second terminal of said inner conductor; and an impedance compensation means having a hole for said extendible pin, wherein diameter of said inner conductor remains practically identical between said first and said second terminals, while diameter of said extendible pin is smaller than that of said inner conductor, wherein said impedance compensation means includes a protrusion part formed in the center thereof to protrude toward a location where said extendible pin is connected, wherein said protrusion formed at said impedance compensation means satisfies the conditions b≦a/5 and c≦2b, when diameter of said impedance compensation means is a, thickness thereof is b, and size of said protrusion is c.
