Definitions
- the present invention relates to an assembly of twisted insulated electrical conductor wires. It applies typically, but not exclusively, to the fields of energy and / or telecommunication cables, and more particularly to low voltage cables used in the building, with a maximum voltage of 750 V, in accordance with European standards H07VU, H07VK, 07Z1U and 07Z1K.
- Document FR 2 122 323 discloses an assembly of easily separable insulated electrical conductor wires without special tools adapted for this purpose.
- the insulated electrical conductor son of this assembly are juxtaposed side by side so as to form a sheet of insulated electrical conductors son.
- hot melt glue beads well known under the anglicism "Hot MeIt", to join insulated electrical conductors son to each other.
- These hot melt glue beads are in some places interrupted to allow separation and connection of said insulated electrical conductors.
- the sheet structure is mainly flexible in only one direction, it becomes very difficult to introduce into a protective sheath, and secondly, the hot melt glue being very elastic ( elongation at break of at least 140%), the separation of the insulated electrical wires where said glue is present, is not easy.
- the object of the present invention is to overcome the drawbacks of the techniques of the prior art by proposing not only an assembly of separable insulated electrical wires easily whatever is the location of the separation along the assembly and without the aid of specific tool, but also an assembly having a very good mechanical holding of all the insulated electrical conductors son along the assembly.
- the present invention relates to an assembly comprising:
- each electrical conductor wire being surrounded by an insulating material
- thermoplastic holding material characterized in that the insulated electrical conductor wires are twisted together, thus forming a twist, and in that said thermoplastic holding material is arranged to connect together all the insulated electrical conductor wires of the twisted such that each insulated electrical conductor wire is connected to at least one insulated electrical conductor wire adjacent thereto, and such that a portion of the insulating material of at least one isolated electrical conductor wire of the twist remains identifiable visually from the outside of the assembly.
- twists used to assemble the insulated electrical conductor son according to the invention are well known to those skilled in the art and may be in particular continuous spiral or alternating right / left.
- the electrical conductor son isolated from the twist are thus maintained using the holding material.
- the twist of the insulated electrical conductor wires combined with their mechanical retention along the assembly makes it possible to obtain an assembly with multidirectional flexibility: the operations of manipulation and introduction into protective sheaths are found then facilitated significantly.
- Another advantage lies in the fact that the part of the insulating material of at least one insulated electrical conductor wire, typically comprising a color marking, remains visually identifiable from the outside of the assembly since the thermoplastic holding material does not cover totally said insulating material.
- the thermoplastic holding material is chosen from materials having the following physicochemical characteristics: i. a product P of the density of the thermoplastic holding material in g / cm 3 by the separation force in MPa between two insulated electrical conductor wires connected via the thermoplastic holding material, ranging from 1.5 to 3, and ii. an elongation at break ranging from 80% to 120%, preferably from 90% to 110%.
- thermoplastic holding material advantageously make it possible to separate at any point along the assembly one or more electrical conductor wires isolated from the twist, and this manually, without the aid of a specific tool.
- all the insulated electrical conductors are on the outer periphery of the twist.
- the twist formed by the insulated electrical conductor son according to the invention thus does not include insulated electrical conductor wire at its center.
- a part of the insulating material of each electrical conductor wire isolated from the twist remains visually identifiable from the outside of the assembly, preferably the part of the insulating material of each insulated electrical conductor wire remains identifiable continuously along the 'assembly.
- two insulated electrical conductor wires are in contact, they form a groove, or void space, on the outer surface of the twist. We will speak in the following description of "outer groove”.
- the thermoplastic holding material is disposed continuously along the assembly, preferably in the outer groove or grooves, the mechanical holding of the assembly is homogeneous over the entire length of the assembly.
- the thermoplastic holding material comprises at least one polyvinyl chloride and / or at least one polyolefin, in particular meeting the physicochemical characteristics i and ii, and can of course be a mixture of polyvinyl chloride and / or polyolefins.
- the thermoplastic holding material may further comprise at least one elastomer in an amount such that the thermoplastic holding material can retain its thermoplastic properties, and in particular meet the physicochemical characteristics i and ii.
- thermoplastic holding material is identical to the insulating material of the insulated electrical conductor wires.
- thermoplastic holding material further comprises at least one additive chosen from slip agents, rodent repellents, and tracers of physicochemical phenomena, or a mixture thereof.
- slip agent of waxes, oils or solid lubricants ("dry lubricants”); as a rodent repellant, aromatic ketones; and as an agent tracer of physicochemical phenomena, cellulosics, acrylics, or ketones esters.
- the number of insulated electrical conductor wires of the assembly according to the invention may preferably range from 2 to 6. According to another characteristic, each electrical conductor wire
- Another object of the invention is a method of manufacturing the assembly as defined above, the method comprising the steps of: A. twisting together insulated electrical conductor wires arranged parallel to each other, to form a twist, and
- step B arranging the thermoplastic holding material so as to connect together all the insulated electrical conductors son of the twist obtained in step A through the thermoplastic holding material so that each electrical conductor wire isolated from the twist is connected at least one insulated electrical conductor wire adjacent thereto, and such that a portion of the insulating material of at least one electrical conductor wire isolated from the twist remains visually identifiable from outside the assembly.
- Steps A and B can be performed in "tandem", that is to say continuously one after the other on the same production line, or "recovery", that is, ie discontinuous.
- step B is carried out using an extruder by extruding and depositing, preferably continuously along the assembly, the thermoplastic holding material around the twist, in the outer grooves of said twist.
- Extrusion is typically a so-called "stuffing" extrusion.
- the internal structure of the die at the exit of the extruder prevents the thermoplastic material for maintaining completely cover the entire twist in order to leave apparent part of the insulating material of the insulated electrical conductor wire (s), preferably of all the insulated electrical conductor wires constituting the assembly.
- This type of manufacturing process is well known to those skilled in the art.
- Figures 1 to 4 schematically show cross-sectional structures, different assemblies of insulated electrical conductors, or "insulated son", according to the present invention.
- FIG. 5 schematically represents in longitudinal section the extrusion head of an extruder during the step of depositing the thermoplastic holding material on a twist according to the invention.
- FIG. 1 illustrates an assembly 10 of two insulated wires 1, each insulated wire 1 comprising a central conductive core 2 surrounded by an insulating material 3. These two insulated wires are brought into contact and twisted together.
- a thermoplastic holding material 4 is extruded and continuously deposited in the outer grooves 5 formed between the two insulated wires to join them. Said thermoplastic holding material fills the outer grooves 5 so that the outer diameter of the circular cross section in which the thermoplastic holding material is inscribed is less than the outer diameter of the circular cross section in which is inscribed the twist. As a result, the thermoplastic holding material does not completely cover the twist and leaves a portion 3a of the insulating material of each insulated wire 1 visible along the assembly 10.
- FIGS 2, 3 and 4 show other examples of assembly 11, 12, 13 respectively comprising three, four and five son 1 twisted.
- a thermoplastic holding material 4 is extruded and continuously deposited in the outer grooves 5 formed between each insulated wire to join them. Said thermoplastic holding material fills the outer grooves so that the outer diameter of the circular cross section in which is inscribed the thermoplastic holding material is less than the outer diameter of the circular cross section in which the twist is inscribed. As a result, the thermoplastic holding material does not completely cover the twist and leaves the portion 3a of the insulating material of each insulated wire 1 visible along the assembly 11, 12, 13.
- the assembly includes no wire in the center of the twist.
- FIG. 5 schematically represents the extrusion head 20 of an extruder in longitudinal section, during the step of depositing the thermoplastic holding material on a twist 14 of insulated electrical conductor wires 1, according to the invention.
- This extrusion head 20 comprises a die 21 of internal diameter d output identical to the diameter in which is inscribed the twist 14.
- a guide punch 22, also of internal diameter d output, is positioned upstream of the die 21.
- a splitter channel 23 makes it possible to bring a flow of thermoplastic material for maintaining the molten state at the level of the twist 14, said splitter channel 23 being positioned between the die 21 and the guide punch 22.
- the twist 14 turns on itself according to the arrow Fl while scrolling in the direction of the arrow F2.
- the internal diameter d of exit of the die 21 makes it possible to prevent the thermoplastic holding material from covering the whole of the twist, and to deposit only the thermoplastic holding material in the outer grooves of the twist
- the guide punch 22 allows for centering the twist to ensure a uniform extruded thickness of the thermoplastic holding material along the twist, and to avoid a return of material (thermoplastic material holding) in the splitter channel 23.
- An assembly is produced as shown in FIG. 2 by helically twisting three insulated wires each comprising a conductive core with a cross section of 1.5 mm 2 covered by an insulating layer of a PVC material having an average thickness of 0.7 mm, said PVC material being marketed by INEOS Compounds under the reference GGA 100.
