CONNECTING ELEMENT FOR MECHANICAL CONNECTION OF FRAMES OF DISTRIBUTION DEVICES Russian patent published in 2019 - IPC H02B1/30 H02B1/01 

FIELD: electricity.

SUBSTANCE: connecting element (1) for mechanical connection of frames (2, 3) of distribution devices to each other comprises connecting part (4) of base, having support surface (5), suitable for support on and connection with profile rack (6) of first frame (2) of distribution device; blockable mating part (7) protruding from connection part (4) of the base and configured to interface with an additional interlockable mating part of an additional connecting element connected to the corresponding profile rail (6') of second frame (3) of the distribution device, wherein interlocking mating part (7) has through hole (8) extending along insert axis (9) and suitable for interaction with additional through hole of additional interlocked mating part to receive locking pin element (10) in parallel to longitudinal axes (11) of shaped racks (6, 6'). Lockable mating part (7) comprises first alignment surface section (12, 23) inclined relative to insert axis (9) and configured to achieve mutual positioning of distribution frames (2, 3) in accordance with first direction (F1), parallel to longitudinal axes (11), and the desired relative lateral position in accordance with the second direction (F2) orthogonal to longitudinal axis (11) and said support surface (5). Lockable mating part (7) and connecting part (4) of the base comprises a second alignment surface section (13, 14) parallel to insert axis (9), and inclined relative to support surface (5), and configured to provide mutual alignment of two frames (2, 3) of distribution devices in accordance with third direction (F3) orthogonal to axis (9) of insert and parallel to support surface (5). Also described are a set of connecting elements and a distribution device comprising a frame.

EFFECT: invention relates to mechanical connection of frames of distribution cabinets to each other.
