Abstract
Abstract Cable duct for separate cables of different voltage, especially mains cables and telecommunication e.g. telephone, radio and television cables to be taken up in separate longitudinal duct channels and to be connected to terminals of switches, outlets or other appliances in connection chambers of the duct, with transition channels for cables bypassing connection chambers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
A duct assembly for housing a number of electrical conductors in separated relation, which comprises: an elongate, generally U-shaped duct presenting a bottom wall and opposite side walls; an elongate cover bridging between said side walls and cooperating with said duct to provide an elongate enclosure space; a plurality of electrical elements disposed along the length of said cover substantially centrally between said side walls and communicating through said cover with said enclosure space to define longitudinally spaced electrical connection points; and separator means within said enclosure space for dividing said enclosure space into a number of longitudinally continuous and separate conductor channels, different ones of which channels communicate with different ones of said electrical connection points, there being at least three such channels, a first of said channels communicating with a first electrical connection point, a second of said channels communicating with a second electrical connection point while leading past said first electrical connection point, and a third of said channels leading past both said first and said second electrical connection points.
Claim 2
Dependent Claim
173 words
A duct assembly for housing a number of electrical conductors in separated relation, which comprises: an elongate, generally U-shaped duct presenting a bottom wall and opposite side walls; an elongate cover bridging between said side walls and cooperating with said duct to provide an elongate enclosure space; a plurality of electrical elements disposed along the length of said cover substantially centrally between said side walls and communicating through said cover with said enclosure space to define longitudinally spaced electrical connection points; and separator means within said enclosure space for dividing said enclosure space into a number of longitudinally continuous and separate conductor channels, different ones of which channels communicate with different ones of said electrical connection points, there being at least three such channels, a first of said channels communicating with a first electrical connection point, a second of said channels communicating with a second electrical connection point while leading past said first electrical connection point, and a third of said channels leading past both said first and said second electrical connection points.
Claim 3
Dependent Claim
27 words
A duct assembly as defined in claim 1 wherein said separator means comprise resilient uninterrupted separator strips extending widthwise thereof between said bottom wall and said cover.
Claim 4
Dependent Claim
41 words
A duct assembly as defined in claim 2 wherein said bottom wall is provided with a plurality of longitudinally extending and laterally spaced grooves, and fastener means received in said grooves for securing each separator strip along one side edge thereof.
Claim 5
Dependent Claim
27 words
A duct assembly as defined in claim 2 including a plurality of comb members disposed transversely in said duct at longitudinally spaced points for locating said strips.
Claim 6
Dependent Claim
82 words
A duct assembly as defined in claim 1 wherein said separator means includes an insert located at each of said electrical connector points, each insert comprising a pair of transverse wall members and a plurality of longitudinally extending wall members, said transverse wall members having openings adjacent the opposite ends of each longitudinally extending wall member, and said separator means also including separator strips extending between opposing transverse wall members of adjacent inserts and separating said openings in the transverse wall members.
Claim 7
Dependent Claim
89 words
A duct assembly as defined in claim 5 wherein each insert includes a pair of outer longitudinally extending wall members in which the respective outer wall members of the individual inserts are longitudinally aligned in the duct assembly, and each insert including a further longitudinally extending wall member between said outer wall members, each further wall member being located closer to one outer wall member than to the other wall member whereby said inserts are reversible to communicate different ones of said conductor channels with said electrical connection points.
Claim 8
Dependent Claim
23 words
A duct assembly as defined in claim 5 wherein said transverse wall members are provided with removable sections for forming said openings therein.
Claim 9
Dependent Claim
39 words
A duct assembly as defined in claim 1 wherein said separator means comprise a pair of transverse separator strips disposed on opposite sides of each electrical connection point and longitudinally extending separator strips extending between said transverse separator strips.
Claim 10
Dependent Claim
17 words
A duct assembly as defined in claim 8 wherein said separator strips are provided with removable sections.
