Definitions
- the present invention relates to a multi-wire electrical conductor which is easily connectable and directly weldable.
- Electrical conductors are, in most of their uses, connected to devices, electrical components, or other electrical conductors. In connection operations, an electrical conductor is often cut to the required length and its ends are stripped and inserted into connectors or connection lugs, or soldered at their connection points.
- Certain known multi-wire conductors have their bare or tinned elementary wires maintained assembled by tin or a fusible metal alloy or a plastic material. If their ends are cut or stripped their elementary strands or threads do not flourish. These multi-wire conductors are indeed easily connectable, however during their welding or soldering at their connection points, these known multi-wire conductors require a supply of a solder flux and most often a supply of solder. It appears that these known multi-wire conductors are not directly weldable or brazable.
- the conductive core of this electrical conductor comprises a core formed at least of a metal wire and of a freely sliding envelope around it. core and made of metallic wires glued against each other. When the conductor is cut and stripped, the conductive core does not flourish thanks to this envelope formed of wires glued to each other, which facilitates its connection.
- An important characteristic described is the use of materials which achieve adhesion of the metal wires which form this envelope but prevent any bonding between this envelope and the core of the conductive core of this conductor.
- tin or a tin alloy can be used to form wires constituting this envelope or their coating, and nickel or chromium to form the core, its component wires or their coating.
- nickel or chromium to form the core, its component wires or their coating.
- the aim of the present invention is to avoid these drawbacks, makes it possible to produce a multi-wire electrical conductor the ends of which, cut and / or stripped on the one hand, do not have strands of strands or twists that are flourishing or capable of flourishing easily, which interfere with the introduction of these ends into connectors and connection lugs, and their welding at the connection points and on the other hand, are directly weldable or solderable, without requiring neither the addition of solder or fuse alloy metal, nor flux Welding.
- a multi-wire electrical conductor having a conductive core formed by one or more strands of elementary metal wires, coated with a layer of metal or fusible alloy usable as solder, is characterized in that it comprises a solder flux enveloping these elementary metal wires and fulfilling at least two functions, a function of a binder for holding these elementary wires in their assembled state facilitating the connection of the conductor, and an inherent function of solder flux to allow direct welding of the conductor to its connection point under the effect of heat and without the addition of material.
- a multi-wire electrical conductor 1 usually comprises a conductive core formed by one or more strands or twists of elementary metal wires 2 schematically illustrated in FIG. 1. This electrical conductor 1 is often protected by an outer sheath, not shown, formed by one or more layers of electrically insulating material.
- the elementary wires 2 are frequently individually tinned metal wires.
- the conductor 1 is transversely cut and rid of its outer sheath at its ends, the strands or elementary wires 2 of its conductive core, relax and open out freely or tend to open out at the slightest mechanical shock.
- a blooming of the strands or elementary wires 2 of the stripped ends of the conductor 1 makes it difficult to solder them or introduce them into usual connectors or connection lugs (not shown).
- the usual tinning of the metallic core of the elementary wires 2 is intended to protect these wires against corrosion or oxidation and to allow soldering.
- their conductive core is brought to a temperature above 232 ° C, the melting temperature of tin, the elementary wires 2 after cooling do not adhere to each other to form a rigid assembly and do not weld at their points of connection.
- This difficulty of self-welding and welding of these elementary wires or strands 2 is due to the pollution of the tin layer which covers these wires, by oxides formed by residues of wire drawing lubricant, of plastic material covering them or of anticorrosion agent used.
- These elementary wires or tinned strands 2 usually require, for their agglomeration or their welding at a connection point, a supply of metal or of fusible alloy and of solder flux.
- a multi-wire electrical conductor 3 illustrated in FIG. 2, comprises a conductive core formed by one or more strands or twists 4 of elementary wires or strands 5 individually coated with a layer of metal or alloy fuse usable as solder 6 such as tin, and a binder or maintenance product 7 consisting of a material or a mixture of materials.
- This binder 7 is film-forming, that is to say capable of forming a film, adherent, non-corrosive and preferably fusible, and provides at least two functions, a function of maintaining the elementary wires or strands 5 in their assembled state and a solder flux function.
- the metal or the fusible alloy 6 covering the elementary wires 5 consists of a metal or alloy usually serving as a solder such as tin or a tin-lead alloy.
- the multi-wire conductor 3 can also be made rigid over its entire length or locally, that is to say at any point along its length or at its ends by welding the elementary wires 5 together.
- the points of the conductor where rigidity must be obtained are brought to a temperature above the melting temperature of the metal layer or of the fusible alloy usable as soldering 6 of the elementary wires 5.
- the binder layer 7 playing the role of solder flux facilitates their agglomeration by welding.
- the heating of the conductor 3 can be carried out according to a technique known by hot air, by induction, by Joule effect or by high frequency.
- the binder 7 is constituted by a rosin or an activated rosin or a rosin activated or not, and plasticized.
- an activated and plasticized rosin comprises a 20% by weight solution in isopropyl alcohol of a rosin modified by 0.2% by weight relative to the dry matter of an organic chloride such as mono or diethylamine hydrochloride and by 10% by weight relative to the dry matter of a plasticizing resin such as a polyvinyl alcohol.
- the application of the binder 7 to the conductive core of the multi-wire electrical conductor 3 is done by dipping, by spraying or by another known technique during the manufacture of the strand or before the installation of the protective sheath of the conductor 3.
- the application of the binder 7 is done by dipping.
- a strand 8 made up of 19 elementary copper wires, diameter 0.20 mm, individually coated with a layer of tin three microns thick, is unwound from a storage coil 9 and then introduced into a solution 10 of binder 7, contained in a container 11.
- the strand 8 filled with binder 7 is taken out of the tank 11 stripped of an excess of product by a wiping member by compressed air 12, before being introduced into a hot air drying device 13 and then wound up in a reel of storage 14.
- the dipping application of the binder 7 can be carried out on a strand of wires 5 during manufacture.
- the application of the binder 7 is done by spraying, during a stranding operation of the elementary wires 5.
- a solution of binder 7 is sprayed by a device 15 on the elementary wires 5 constituting a twist 4 before they enter a twist 16.
- a sample of this conductor is cut transversely. In the cut end of this conductor 3, it is found that the elementary wires or strands 5 remain well grouped. A section of this sample is brought to a temperature of 250 ° C. which is higher than the melting temperature of the tin. After cooling, it is found that in this conductor section all the elementary wires or strands 5 constituting the conductive core are welded together.
- a multi-wire electrical conductor 3 produced according to the invention thus comprises a multi-wire conductive core formed by one or more strands, which can be cut and stripped without at the level of this cut the elementary wires or strands 5 constituting it break apart and s flourish.
- the connection operations carried out on such a conductor are therefore facilitated and are capable of being fully automated as shown in FIGS. 5 and 6.
- FIGS. 5 and 6 In these figures the connection of a barrel 20, for example internally tinned, is shown, from a connector to a strand 21.
- the strand 21, the outside diameter of which is very slightly smaller than the inside diameter of the barrel, is introduced (FIG. 5) into the latter and heating means 22 surrounding the barrel ensure the melting of the coating of metal or fusible alloy usable as solder 6 coating the strand 21 and tin coating the inside of the barrel, which allows soldering without adding material and solder flux.
