In addition, the elastic portion is divided into a plurality of elongated fine elastic portions so that the elastic portion can elastically bend and deform necessary for floating.

Japanese Patent No. 6849555

In the configuration of Patent Document 1, when the thin elastic portion of the terminal is elongated in order to facilitate elastic bending deformation and ensure floating performance, the strength of the thin elastic portion decreases. Therefore, when the fine elastic portion is press-molded in the manufacturing stage, it is expected that the fine elastic portion may be deformed, resulting in a decrease in productivity. Therefore, it is conceivable to connect adjacent fine elastic portions at a part in the longitudinal direction. However, depending on the arrangement of the connecting portion, the floating performance may be degraded.

An embodiment of the present invention provides a floating connector, a board-to-board connector, and a terminal capable of suppressing a decrease in productivity while ensuring floating performance.

One embodiment of the present invention is a floating connector (1) fitted in a mating direction (X1) to a mating connector (10), comprising a fixed housing (2), a movable housing (3), and power supply terminals (4P; 4P1, 4P2; 4R). The movable housing is movable with respect to the fixed housing. The power terminal includes a fixed portion (4a), a contact portion (4b) and an elastic portion (4c). The fixed part is fixed to the fixed housing. The contact portion is fixed to the movable housing and contacts a mating power terminal of the mating connector. The elastic portion extends in the longitudinal direction (L) from the fixed portion to the contact portion and elastically deforms as the movable housing moves. The elastic portion includes a plurality of slits (4e; 4e1-4e4), a plurality of divided elastic portions (4f), and connecting portions (4g; 4g1-4g4). The plurality of slits are formed side by side in a width direction (W) orthogonal to the longitudinal direction and extend in the longitudinal direction. The plurality of divided elastic portions are divided from each other by the slits and extend in the width direction and in the longitudinal direction. The connecting portion connects two of the divided elastic portions adjacent to each other in the width direction across the slit at an intermediate position in the longitudinal direction so as to cross the slit. The power supply terminal forms one member in which portions other than the divided elastic portion are connected in the width direction. Among the connecting portions, the connecting portions that cross the two slits that are adjacent in the width direction with the divided elastic portion interposed therebetween are arranged with their positions shifted from each other in the longitudinal direction.

This configuration provides the following effects. That is, in order to achieve a larger floating amount, the divided elastic portion of the power supply terminal may be thin and long. On the other hand, according to this configuration, in the power supply terminal, the divided elastic portions that are adjacent in the width direction across the slit are connected at the intermediate position in the longitudinal direction by the connecting portion that crosses the slit. Therefore, it is possible to suppress a decrease in the strength of the split elastic portion, thereby suppressing a decrease in productivity. Moreover, the connecting portions that cross two slits adjacent to each other with the divided elastic portion interposed therebetween are not arranged in the width direction. Therefore, it is possible to suppress the deterioration of the floating performance. Therefore, it is possible to suppress a decrease in productivity while ensuring the floating performance.
