Abstract
Abstract The invention provides an electric duct for locating insulated electric wires along a wall. A removable cover member has internal channels in which wires are located at junction positions adjacent blind holes in the member through which spikes or claws of connectors extend to pierce the insulation on the wires and contact their conductive cores. The wires are retained in their channels by protuberances on a co-operating element which is locked to the cover member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
123 words
An electric duct for locating insulated electric wires along a wall, comprising a movable cover element having predetermined junction positions which are spaced apart and are provided with holes for the passage of contact spikes or claws of junction connectors for the electric wires, which movable cover element has a main wall whose inner face is formed with individal channels for guiding and holding electric wires in positions in which said electric wires pass in front of said holes; and a cooperating element have protuberances on at least one face at the junction positions, which protuberances are spaced apart so as to engage in the channels in order to secure firmly the insulated wires in position into the channels at the junction positions.
Claim 2
Dependent Claim
123 words
An electric duct for locating insulated electric wires along a wall, comprising a movable cover element having predetermined junction positions which are spaced apart and are provided with holes for the passage of contact spikes or claws of junction connectors for the electric wires, which movable cover element has a main wall whose inner face is formed with individal channels for guiding and holding electric wires in positions in which said electric wires pass in front of said holes; and a cooperating element have protuberances on at least one face at the junction positions, which protuberances are spaced apart so as to engage in the channels in order to secure firmly the insulated wires in position into the channels at the junction positions.
Claim 3
Dependent Claim
39 words
An electric duct according to claim 1, including a base element adapted to bear against a wall, and wherein the co-operating element is an intermediate element adapted to be located between the movable cover element and the base element.
Claim 4
Dependent Claim
60 words
An electric duct according to claim 2, wherein the base element is a hollow section having a bottom wall and two side walls, the free ends of which side walls are formed with fastening means, and the movable cover element has on its opposite sides, in the transverse direction, fastening means complementary to the fastening means on the base element.
Claim 5
Dependent Claim
49 words
An electric duct according to claim 1, comprising a flexible hinge joining the co-operating element to the movable cover element, and, on a free end of said co-operating element, means for attaching said co-operating element to the movable cover element when the co-operating element is closed over the channels.
Claim 6
Dependent Claim
46 words
An electric duct according to claim 1, wherein the co-operating element is an independent element having at two opposite ends means for clipping the co-operating element to the movable cover element when the co-operating element is placed transversely on the cover element and covers the channels.
Claim 7
Dependent Claim
28 words
An electric duct according to claim 1, wherein the co-operating element is an independent part adapted to be located in the bottom of a groove in a wall.
Claim 8
Dependent Claim
46 words
An electric duct according to claim 1, wherein the co-operating element is a hollow section having a bottom wall from which the protuberances project and side walls which are joined by fastening means to complementary fastening means on the side walls of the movable cover element.
Claim 9
Dependent Claim
31 words
An electric duct according to claim 1, wherein the free ends of the side walls of the cover element are provided with means for fastening the cover element to a wall.
Claim 10
Dependent Claim
42 words
An electric duct according to claim 1, wherein the channels are defined at each junction position by notches provided in two transverse partitions which are spaced apart longitudinally of the duct and are situated one on each side of the junction position.
Claim 11
Dependent Claim
37 words
An electric duct according to claim 9, wherein at each junction position the side walls of the movable cover element are each lined by an internal longitudinal partition and the transverse partitions extend between the longitudinal partitions.
Claim 12
Dependent Claim
40 words
An electric duct according to claim 1, wherein the channels are defined by pairs of parallel longitudinal ribs of which the ribs of each pair extend one on each side of the connection holes at least at each junction position.
Claim 13
Dependent Claim
31 words
An electric duct according to claim 1, wherein the movable cover element is made up of successive portions and the opposite ends of each portion are provided with complementary attachment means.
Claim 14
Dependent Claim
74 words
An electric duct according to claim 12, wherein at one end the attachment means consists of two bosses spaced apart transversely and having an incurved inner face, and at the other end the attachment means consists of two hooks spaced apart transversely and each having an internal curvature which corresponds to the incurving of the inner face of the bosses and a rounded back adapted to contact the inner face of the fixed element.
