Flat cable transmission system

Claim 2

A multiconductor flat cable trunking module comprising means defining an elongate duct, a flat cable having a plurality of conductors and extending within and along the length of said duct, linking means at each end of said duct, a plurality of socket outlets at intervals along a surface of the duct, and intermediate connections within the duct from said cable to said socket outlets which are formed by a number out of said plurality of conductors which form part of the flat cable along a first part of the length thereof, but which are separated from the remaining conductors along a second part of the length thereof.

Claim 3

A trunking module as claimed in claim 1, wherein said linking means comprise an integral continuation of said cable at the end of the module.

Claim 4

A trunking module as claimed in claim 1, wherein said means for linking comprise electrical connectors on each end of said cable.

Claim 5

A trunking module as claimed in any preceding claim, wherein the duct is closed along its length with no direct access to said cable.

Claim 6

A trunking module as claimed in claim 1, wherein adjacent each socket outlet is physical engagement means for a connector device.

Claim 7

A trunking module as claimed in claim 1, wherein the socket outlets include a telecommunications jack socket.

Claim 8

A trunking module as claimed in claim 1, wherein said means defining an elongate duct has at least two parallel channels, one of which is a duct permanently closed along its length and another of which has a side closed only by a removable panel.

Claim 9

A trunking module as claimed in claim 1, wherein said means defining an elongate duct has at least two parallel channels, one of which is a duct permanently closed along its length and another of which has an open side, the socket outlets being in the closed duct.

Claim 10

A trunking module as claimed in claim 8, wherein the surface of the closed duct containing the socket outlets is parallel to the open side of the other duct.

Claim 11

A trunking module as claimed in claim 8 or 9, wherein further socket outlets are fixed over said open side.

Claim 12

A cable trunking system including a plurality of trunking modules each comprising means defining an elongate duct, a flat cable having a plurality of conductors and extending within and along the length of said duct, linking means at each end of said duct, a plurality of socket outlets at intervals along a surface of the duct, and intermediate connections within the duct from said cable to said socket outlets which are formed by a number out of said plurality of conductors which form part of the flat cable along the first part of the length thereof, but which are separated from the remaining conductors along a second part of the length thereof, said plurality of trunking modules being connected together via interconnection of said linking means.

Claim 13

A cable trunking system including a plurality of trunking modules each comprising means defining an elongate duct, a flat cable having a plurality of conductors and extending within and along the length of said duct, linking means at each end of said duct, a plurality of socket outlets at intervals along a surface of the duct, and intermediate connections within the duct from said cable to said socket outlets which are formed by a number out of said plurality of conductors which form part of the flat cable along the first part of the length thereof, but which are separated from the remaining conductors along a second part of the length thereof, said plurality of trunking modules being connected together via interconnection of said linking means.

Claim 14

A trunking system as claimed in claim 11, wherein said plurality of elongate ducts of successive modules are serially connected end to end.

Claim 15

A trunking system as claimed in claim 11, which includes intermediate ducts which enclose said flat cable, which intermediate ducts have no socket outlets and are physically connected to the elongated ducts.

Claim 16

A trunking system as claimed in claim 12 or 11, which includes intermediate ducts which enclose said linking means between said flat cable, which intermediate ducts have no socket outlets and are physically connected in-between the elongate ducts.
