Homogeneous power units'frames connecting device for switchgear, has adapters switching from spaced position to approximated position in approximation direction, while locking pin is inserted into one opening of fingers

摘要

The device (3) has two adapters (4, 5) having spaced and approximated positions with respect to each other. Openings of fingers (8, 9) of the adapters partially overlap in the spaced position so that insertion of an end of a locking pin (6) through one of the openings is possible. Contours of the openings are overlappingly arranged in the approximated position. The adapters switch from the spaced position into the approximated position in an approximation direction that corresponds to a direction of overlap of the fingers, while the locking pin is inserted into the opening.
