Multi-pole coaxial connector

A multi-pole coaxial connector comprising:

• a coaxial cable connecting body in which a plurality of combinations of a signal post connected to an internal conductor of a coaxial cable, and a ground contact which is fitted over the signal post through an insulator and which is further connected to an external conductor, are disposed in parallel to each other, and
• a stationary side connecting body in which a plurality of combinations of a signal contact having a signal terminal and a ground case having a ground terminal are disposed in parallel to each other, in which the coaxial cable connecting body and the stationary side connecting body are coupled to each other so as to bring the signal post and the signal contact into conduction, the ground contact and the ground case into conduction, the internal conductor and the signal terminal into conduction and the external conductor and the ground terminal into conduction,
• wherein a cross section of the ground contact is substantially a U-shape in which adjacent ground contact side is opened,
• wherein the signal contact includes a pair of contact pieces which sandwich the signal post from both sides with a compression force,
• wherein the ground case is fitted over the signal contact through an insulator and is sandwiched between a pair of contact pieces of the ground contact with a compression force, and
• wherein opening and closing directions of the pair of contact pieces of the ground contact and opening and closing directions of the pair of contact pieces of the signal contact are different from each other.
