Detailed Description
In order to further illustrate the technical means and technical effects adopted by the present invention, the present invention is described in detail below with reference to the examples.
As shown in fig. 1, the floating connector of the present invention includes a connector housing 1, power contacts 2 and signal contacts 3 provided in the connector housing, and a flexible board 4 and the like welded to the power contacts and the signal contacts. The connector shell is internally provided with a first positioning groove 5 and a second positioning groove 6 for mounting the power contact element and a mounting groove 8 for mounting the elastic element 7, the mounting groove is positioned between the first positioning groove and the second positioning groove, the power contact element is U-shaped and comprises a first side surface 9, a second side surface 10 and a U-shaped surface 11 positioned between the first side surface and the second side surface, the first side surface 9 is mounted in the first positioning groove 5, and the second side surface 10 is mounted in the second positioning groove 6. The bottom of the first positioning groove 5 is provided with a first positioning table 12 which is used for being matched with a second positioning table 13 on the power contact piece to play a role in limiting the power contact piece. The elastic piece 7 is arranged in the mounting groove and positioned between two side faces of the power contact piece, one end of the elastic piece props against the bottom of the mounting groove, and the other end of the elastic piece props against the U-shaped face of the power contact piece. The signal contact element 3 is arranged in the connector shell in a forced mode.
As shown in fig. 7, a separation groove 14 is provided on the flexible board 4 to divide the flexible board into a first flexible board 15 for welding with the power contact and a second flexible board 16 for welding with the signal contact, and the first flexible board is connected to the second flexible board at one end and separated from the second flexible board at the other end by the separation groove 14. The first flexible board is provided with a first welding hole 17 for welding with a power contact, and the second flexible board is provided with a second welding hole 18 for welding with a signal contact. The first flexible board is also provided with a deformation compensation mechanism which is used for providing certain compensation deformation for the first flexible board welded with the power contact piece when the power contact piece floats, so that effective floating of the power contact piece is realized. The first flexible board and the second flexible board are respectively provided with a first guide hole 19 and a second guide hole 20 which are respectively used for being matched with a first guide post 21 and a second guide post 22 on the connector shell to play a guiding role. The first guiding holes are equal in number and correspond to the first guiding columns, and the second guiding holes are equal in number and correspond to the second guiding columns.
As shown in fig. 5, after the elastic member, the power contact member and the signal contact member are mounted in place, one end of the elastic member abuts against the U-shaped surface of the power contact member, and the power contact member is assembled in the connector housing because the second positioning table of the power contact member is limited by the first positioning table at the bottom of the first positioning groove in the connector housing. When the connector is not plugged, the U-shaped surface of the power contact piece is higher than the contact surface of the signal contact piece under the action of the elastic piece, as shown in figure 2.
When the flexible board is welded with the contact piece, the flexible board is installed at the bottom of the connector shell through the matching of the first guide post and the second guide post on the first guide hole and the second guide hole and the connector shell respectively, and then the power contact piece and the signal contact piece are welded on the flexible board through the first welding hole and the second welding hole respectively.

Furthermore, the first guide post is longer than the second guide post, so that the first flexible board can be ensured to always float under the guidance of the first guide hole and the first guide post when the power contact element floats, and the deformation of the deformation compensation mechanism during floating ensures effective floating without influencing the whole flexible board.
Further, the deformation compensation mechanism is a groove 23 which is semicircular or arc-shaped and integrated with the first flexible board, and the groove is concave towards the direction of the power contact piece moving when the floating connector and the inserting end are inserted, as shown in fig. 1.
Further, the elastic element is a spring or other parts with elastic deformation function.
