Koblingsindretning for kabelbakkedele

摘要

A device for coupling cable tray components comprises a strip of metal bent to define a central web (42) disposed in one plane and respective connector sections (44) at each end of the web (42) and disposed laterally to the same side of the plane of the web (42) as each other. At least one of the connector sections (44) has an upstanding proximal portion (46) and a distal portion (48), the distal portion (48) being bent so as to be directed back towards the plane of the web (42) and is capable of resiliently flexing towards the proximal portion (46). The other connector section (44) may consist of a tongue (50) disposed substantially in parallel with the central web (42) but laterally offset relative thereto by step or joggle (52). Cable trays may be clipped together by inserting the connector sections (44) into aligned apertures of the trays. The flexural return of the distal portion (48) to its unstressed position serves to hold the connector sections (44) in position.
