As shown in fig. 8 and 9, the side sectional view and the other side sectional view of the conventional floating connector are respectively the side sectional view of the conventional floating connector, in the coaxial connector a with a floating mechanism, the housing a1 has a base a11 fixed in a metal housing B, a movable portion housing a12 is provided to the base a11, the movable portion housing a12 moves together with the internal terminal C, a floating spring D is provided with one end fixed to the base a11 and the other end fixed to the movable portion housing a12, the floating spring D is fixed to the base a11 by a support fixing portion D1 and the floating fixing portion D2 is fixed to the movable portion housing a12, and an elastically deformable swinging spring portion D3 and an impedance adjusting portion D4 are connected between the support fixing portion D1 and the floating fixing portion D2, and a support fixing portion D1 of the floating spring D, The metal case B in the direction intersecting the floating fixed portion D2 is provided with a pair of elastic contact pieces B1 facing each other with a space therebetween, and the pair of elastic contact pieces B1 is located outside the movable portion case a12 so that the movable portion case a12 and the internal terminal C can move in the direction between the two elastic contact pieces B1, and the internal terminal C and the spring body D can be integrated into a floating integrated spring E made of a conductive metal plate material.

In the conventional coaxial connector, the base portion a11 of the housing a1 is fixed in the metal shell B, but the movable part housing a12 is only fixed on the floating fixing portion D2 of the spring body D, and the movable part housing a12 is only supported and limited by the floating fixing portion D2, so that the radial deflection or the axial pulling displacement is serious, and the overall structure between the base portion a11 of the housing a1 and the movable part housing a12 is not stable; when the coaxial connector is mated with another coaxial connector, the movable part housing a12 is displaced in a large radial direction (horizontal direction) and in a large axial direction (vertical up and down direction), and the floating fixing part D2 is also displaced in the radial direction (horizontal direction), bent, deformed and pulled in the axial direction (vertical direction), so that the floating fixing part D2 is subjected to torsion such as bending deformation and pulling during displacement, and the floating fixing part D2 is easily bent and broken.

In addition, even when the movable portion case a12 is displaced in the radial direction (horizontal direction) due to the abutting, the internal terminal C is easily pushed in the radial direction (horizontal direction), and the internal terminal C is fixed in the base portion a11 of the case a1, and is not provided with a space for elastic displacement and deformation, and is also easily subjected to twisting deformation or breakage due to the pushing in the radial direction (horizontal direction) of the movable portion case a 12.
