Patent ID: 8197287

Claim:
Coaxial connector having an outer conductor which has a first end for insertion, and a second end for insertion in an axially opposite position from the first end for insertion of the outer conductor, and having a center conductor which has a first end for insertion, and a second end for insertion in an axially opposite position from the first end for insertion of the center conductor, the outer conductor comprising two separate parts, with a first outer-conductor part forming the first end for insertion of the outer conductor and a second outer-conductor part forming the second end for insertion of the outer conductor, the two parts of the outer conductor being so arranged and designed that they can be moved relative to one another in the axial direction and to move in the axial direction relative to the center conductor, and there being provided on the outer conductor a first elastic resilient member which forces the two outer-conductor parts of the outer conductor away from one another in the axial direction, the center conductor comprising two separate parts, with a first center-conductor part forming the first end for insertion of the center conductor and a second center-conductor part forming the second end for insertion of the center conductor, the two parts of the center conductor being so arranged and designed that they can be moved relative to one another in the axial direction, characterized in that the outer conductor takes the form, between the two outer-conductor parts, of an resilient outer-conductor bellows, the resilient outer-conductor bellows being so designed that, if there is a change in the length of the resilient outer-conductor bellows, a varying capacitance of the resilient outer-conductor bellows is compensated for by an inductance of the resilient outer-conductor bellows which varies correspondingly in the opposite direction, in such a way that, if there is a change in the length of the resilient outer-conductor bellows, the characteristic impedance of the coaxial connector remains substantially constant, the center conductor taking the form, between the two center-conductor parts, of a resilient center-conductor bellows, the resilient center-conductor bellows being so designed that, if there is a change in the length of the resilient center-conductor bellows, a varying capacitance of the resilient center-conductor bellows is compensated for by an inductance of the resilient center-conductor bellows which varies correspondingly in the opposite direction, in such a way that, if there is a change in the length of the resilient center-conductor bellows, the characteristic impedance of the coaxial connector remains substantially constant.
