Floating

Overview:What are floating type connectors?

It has a structure in which an insulator housing, colored green in the figure on the right, of a mated pair of connectors is like floating. It is impossible to mate general rigid connectors if they are mounted out of precise alignment, but is possible with the floating type connectors. Even if connectors are mounted out of alignment, it is possible for a floating type connector (colored green) to move in the floating space to mate to the counterpart connector properly. Thus the connectors absorb the positional deviation on boards and positional deviation generated in installing boards on which the connectors are mounted to the customers' units.

Advantages in using them

By using floating type connectors:
1) It is possible to use plural pairs of connectors on a single printed circuit board,
2) The degree of freedom in component layout and in circuit design increases,
3) The stress applied to the solder joints decreases to suppress solder cracks.
Kyocera's floating type connectors achieve movability of F/P*1=200% at maximum and it is possible to solve customers' problems at design by their high contact reliability.

The spring part of contacts expands or contracts, and the movable insulator housing colored green follows it.
