Abstract: The present invention relates to a system for unmating a board-to-board high pin count connector pair, said connector pair comprising two connector elements adapted to be mated together and fixedly mounted on two respective boards; said connector pair is so configured that the two boards are substantially parallel when the two connector elements are mated together; the system according to the present invention comprises at least two cam elements rotatably mounted on a first board on opposite sides with respect to the corresponding connector element and rotation means adapted to manually rotate the cam elements so as to apply a force to a second one of the two boards when the two connector elements are mated together, thereby unmating the connector pair.

Abstract: The invention relates to a connection system between a printed board and a cable, in particular a fiber optic cable mounting a connector connectable by rotation and to a bush for use in this connection system. The system is characterized by the use of a bush so disposed as to shift on the back-panel the draw out stress exerted on the connector preventing its axial sliding and therefore the drag and rupture of the fiber optic cable if the connector has not been unscrewed in advance.
