DEVICE FOR SERIES CONNECTION OF CONTACT BUS DUCTS Russian patent published in 2013 - IPC H01R25/14 

FIELD: electricity.

SUBSTANCE: invention refers to devices for series connection of two contact bus ducts, each of which includes plastic profile and at least one collecting bus passing inside along it, with one connector of collecting buses, which in-series connects electrically and mechanically the ends of collecting buses of two contact bus ducts. On each of opposite lying ends of buses of connected contact bus ducts there fixed is intermediate element, and on intermediate elements there fixed are additional elements with possibility of being moved in longitudinal direction relative to intermediate elements. Proposed device involves easy shortening of contact bus ducts at assembly site, and pluggable intermediate elements give the required shape for receiving additional elements. Contact bus ducts are built as modular system and consist of plastic profile, intermediate element and additional element. Each intermediate element is made in the form of coupling, put on end of bus of contact bus duct and fixed by means of fastening elements on the end of bus of contact bus duct.

EFFECT: easier manufacture and installation of intermediate elements.
