PURPOSE:To scale up transmission speed and to realize high speed advancement of transmission speed of a communication device by matching the impedances at a contact piece so as to decrease attenuation of signals. CONSTITUTION:For junction between a connection terminal 1 and a circuit board 1 in connection struction of the circuit board, the flange 2a-1 of an external conductor 2a is pressure-bonded by seam welding 1d to a peripheral pattern 1a for earth at the same time when a center conductor 2b is inserted into a through hole 1c. On the other hand, a contact socket 3b which is provided with a slit 3b-1 and has a spring property hole and connects with a connection terminal 2a and a cylindrical external conductor 3a which is provided with a slit 3a-1 and has spring property and connects with the external conductor 2a of the connection terminal 2 constitutes a coaxial connector through a dielectric 3a in a connection terminal 3 to connect with the connection terminal 2. Those are made into a pair of coaxial connectors that this connection terminal 2 and connection terminal 3 can be inserted into or pulled out from each other in the arrow direction, and matching the impedances at a connection the attenuation of signals is decreased so as to make the stable transmission speed above the specified level. |
