The present invention is not limited to the shield connector of the present embodiment described above, and it goes without saying that various modifications are possible. For example, in the above-described embodiment, the first and second contact pieces 2 of the cantilever type are used.
Although the description has been made with reference to 3, 24, the present invention can also be applied to a double-sided contact piece. Further, although the flexible contact piece is formed by being folded inward, it is also possible to form the flexible contact piece by being folded outward. Further, in the present embodiment, the case where four sets of the first and second contact pieces 23 and 24 are provided in a one-to-one set has been described. It can also be provided radially outside of the part 21.

As described above, in the shielded connector according to the present invention, the flexible contact piece that comes into contact with the mating connector is integrally connected in front of the metal shell, and at least the bent portion of the flexible contact piece is provided. A ridge for improving the bending stiffness of the flexible contact piece in the longitudinal direction is formed on the flexible contact piece. Therefore, since the flexible contact pieces are integrally connected to the metal shell, the number of components can be reduced, the manufacturing cost of the metal shell can be reduced, and the man-hour for assembling to the connector housing can be reduced. In addition, since the ridge is provided to improve the bending rigidity in the longitudinal direction of the flexible contact piece, even if the metal shell is press-formed from an inexpensive metal plate having a low Young's modulus, the electrical connection between the metal shell and the mating connector can be made. A reliable connection state can be reliably obtained.

Further, when the flexible contact piece is composed of a pair of contact pieces having different width dimensions, and the contact pieces are arranged adjacent to each other, the bending rigidity of the flexible contact piece and the amount of flexure that can be elastically deformed. Can be changed. Therefore, even if the dimensions of the mating connector vary, one of the flexible contact pieces comes into contact with the mating connector, and the electrical connection between the metal shell and the mating connector is reliably obtained. be able to. Further, since the contact pieces having different dimensions in the width direction are arranged adjacent to each other, the load applied at the time of fitting with the mating connector is received by the flexible contact piece having a large width and high bending rigidity, and the width is reduced. It is possible to prevent plastic deformation of the flexible contact piece that is narrow and has low bending rigidity.

Further, when a plurality of pairs of flexible contact pieces are provided at opposite positions on the front end of the cylindrical portion of the metal shell, and the contact pieces having the same width are arranged symmetrically with respect to the axis of the metal shell. Even if the mating connector is misaligned in any direction, the flexible contact piece can be reliably brought into contact with the mating connector. Therefore, according to the shielded connector of the present invention, since the press forming is performed integrally from an inexpensive metal plate, the manufacturing cost is low, and a pair of contact pieces having different widths, which are arranged adjacent to each other, are opposed to each other. Since a plurality of sets are arranged, a shielded connector having excellent assemblability and high reliability can be obtained.
