Abstract
Steel trunking is provided for housing transmission cables particularly in areas where hygiene and sterility is important. The invention provides lengths of hollow conduit which are secured together by push-on connectors in the form of sleeves. There is also provided a transmission cable outlet device (20) with a hollow body member terminating in an end plate (33). The end plate (33) carries glands (34) which grip and hold cables so as to provide a clean and efficient take-off from the trunking.
Claims43
A steel trunking assembly for housing transmission cables comprising:
- a plurality of lengths of steel conduit circular in cross section having exposed end faces;
- bored connectors for securing the lengths of conduit together, each connector comprising at least two connector inlets, each for reception of the free end of the conduit and each connector inlet having a conduit receiving bore extending from an open conduit receiving mouth to an internal conduit restraining stop, the diameter of the bore being such as to provide a snug fit of the conduit within the bore;
- and
- a bored sleeve of a plastic material forming a force fit within the conduit, the sleeve having a stop engaging annular flange projecting across the exposed end face of the conduit.
