Patent ID: 8231398

Claim:
A co-axial connector including: an outer-conductor having 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; a center-conductor having 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 center-conductor comprising two separate parts, 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 moveable relative to one another in the axial direction, the center-conductor forming a resilient inner bellows between the two center-conductor parts, the resilient bellows including a capacitance that varies with a change in length which is compensated for by an inductance which varies correspondingly in the opposite direction, such that, if there is a change in the length of the resilient bellows, the characteristic impedance of the co-axial connector remains substantially constant; the outer-conductor comprising two separate parts, 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 movable relative to one another in the axial direction, the outer-conductor including a first outer elastic resilient spring member which abutted against the two parts for forcing the two parts of the outer-conductor away from one another in the axial direction; the first center-conductor part movable in the axial direction relative to the first outer-conductor part, the second center-conductor part movable in the axial direction relative to the second outer-conductor part, the center-conductor including a second inner elastic resilient member forcing the two center-conductor parts away from one another in the axial direction; and at least one stop for limiting the movement of the two center-conductor parts away from one another in the axial direction, the at least one stop being formed on each of the outer-conductor parts.
