    [0001] BACKGROUND OF THE INVENTION 1. The method of crimping an electrical contact on a cable and tool for the implementation of this method [001] The invention relates to the field of electrical connection. The invention particularly relates to a method of crimping an electrical contact on an electric cable, an electrical contact crimped with this method, and a tool for implementing this method. [002] Connectivity, it uses the coupling of male and female electrical contacts to make an electrical connection between cable connectors or between a cable connector and an electrical or electronic device for example. In the case of a cable connector, male or female contacts are electrically connected, by welding, crimping or otherwise, to a cable having one or more strands. [003] In automotive connection, the contacts are often made by stamping and bending of a copper sheet. The cables are usually also copper. [4] To reduce the weight of electric harnesses in vehicles in particular, copper cables are sometimes replaced by aluminum cables with several conductive strands. The replacement of copper cables with aluminum cables poses several problems. Primarily, since aluminum is covered with an oxide layer, the electrical conduction at the contact areas between an aluminum cable and a copper contact can be reduced. In order to overcome this problem, it is sought on the one hand to break the oxide layer to have better conductivity and, on the other hand, to avoid the reformation of this oxide layer after crimping. For this purpose, the compression ratio of the cable in the crimping zone can be increased. But this increase in the compression ratio induces a decrease in the mechanical strength of the cable in the area thus compressed. [5] US 7306495B2 discloses a crimping method in which an electrical cable having a plurality of aluminum conductive strands is provided, and an electrical contact with a crimping zone extending in a longitudinal direction and comprising a base and two fins each extending from one side of the base to form a groove having substantially a U-shape in section in a plane perpendicular to the longitudinal direction. [6] In this method, the crimping zone is crimped onto the cable by folding and compressing the fins on the cable. For this purpose, a tool comprising a punch having two different crimping heights is used. A crimping zone is then obtained which, after crimping, itself comprises a mechanical retention portion and an electrical conduction portion. The portions of mechanical retention and electrical conduction are in continuity material with each other. In other words, starting from a contact with a single fin on each side of the cable, without cutting these fins or slot separating them in several portions, a continuous crimping drum is obtained in the longitudinal direction. The mechanical retention and electrical conduction portions have different final crimping heights, the final crimping height of the mechanical retention portion being higher than the final crimping height of the electrical conduction portion. [7] Thus, in the mechanical retention zone, the strands of the cable are less compressed (the compression ratio is for example between 20 and 30%), the integrity of their mechanical properties is therefore essentially preserved and the retention cable in the crimping drum meets the specifications. For example, for a 1.5mm2 copper wire, this retention force must be greater than 155N. In the electric conduction zone, the strands of the cable are further compressed (the compression ratio is for example between 50 and 65%), the mechanical properties are thus degraded with respect to the mechanical retention zone. On the other hand, the electrical resistivity in the electric conduction zone is lower than in the mechanical retention zone. However, it can be observed, in certain cases, that the electrical and mechanical properties of the contacts crimped with this type of process are degraded over time. An object of the invention is to at least partially overcome this disadvantage. To this end, there is provided a method of crimping an electrical contact, as mentioned above, in which, in addition, the difference between the final crimping heights of the mechanical retention portion. and the electrical conduction portion is between 0.4 and 0.7 mm or even less and between 0.5 and 0.6 mm in some cases. With this arrangement (which can result for example from the geometry of the crimping punch), the deformations of the contact in the transition zone between the mechanical retention portion and the electrical conduction portion are limited and the contact does not include no crack or tear. In addition, if the copper contact is coated with a protective layer, for example tin, the integrity of it remains. It is thus possible to avoid problems of electrolytic corrosion due to the differences in electrochemical potentials between the cable and the contact. [0012] In addition, one or the other of the following features may be provided independently or in combination with one or more of the following: [0013] crimping is carried out by compressing the fins at the level of the portion of electrical conduction over a distance, in the longitudinal direction (when the contact is positioned in the crimping tool comprising the punch), greater than or equal to 1.5 mm; and [0014] crimping is accomplished by compressing the fins at the electrical conduction portion and at the mechanical retention portion at constant heights along their respective length in the longitudinal direction, and with a transition zone between the electrical conduction portion and the mechanical retention portion whose dimension in the longitudinal direction (when the contact is positioned in the crimping tool comprising the punch) is between 0.3mm and 0.6mm. In another aspect, the invention relates to an electrical contact crimped with the method mentioned above. This contact comprises a step between the mechanical retention portion and the electrical conduction portion whose height is between 0.4 and 0.7 mm or even less and between 0.5 and 0.6 mm in some cases. In addition, one or more of the following features can be provided for this contact independently or in combination with one or more of the following: [0017] the step has a rounded internal fold with a radius a curvature of 5 between 0.1mm and 0.5mm; The step has a rounded outer fold with a radius of curvature of between 0.1 mm and 0.5 mm; The sum of the radii of curvature of the inner and outer folds is between 0.3 and 0.5 mm; and [0020] the radius of curvature of the inner fold is between 0.1 mm and 0.2 mm, it is for example equal to 0.1 mm and that of the outer fold is between 0.1 mm and 0, 4mm, it is for example equal to 0.2 mm. In another aspect, the invention relates to a tool comprising a crimping punch for implementing a method of crimping an electrical contact. This punch comprises a groove essentially having a W-shape in section in a plane perpendicular to the longitudinal direction. This groove has two successive segments in the longitudinal direction, a deeper segment for compressing the fins at the mechanical retention portion and a shallower segment for compressing the fins at the electrical conduction portion, the difference in height. between these two segments being between 0.4 and 0.7 mm, or even less and between 0.5 and 0.6 mm in some cases. It is also possible for this contact to have one or the other of the following characteristics considered independently or in combination with one or more others: [0023] the segment compressing the fins at the level of the portion of electrical conduction has a dimension, in the longitudinal direction, greater than or equal to 1.5mm; The difference in height between the two segments forms a step whose walking edge has a radius of curvature of between 0.1 mm and 0.5 mm; - The bottom of the step is rounded with a radius of curvature of curvature between 0.1mm and 0.5mm; - the sum of the radii of curvature of the walking edge and the running floor is between 0.3 and 0.5 mm; and [0027] - the radius of curvature of the step edge is equal to 0.1 mm and that of the bottom of step is equal to 0.2 mm. Other characteristics and advantages of the invention will become apparent on reading the detailed description and the appended drawings in which: FIG. 1 is a diagrammatic perspective view of an example of contact which has not yet been set on FIG. 2 shows in side elevation the crimping zone of the contact Zo of FIG. 1, after crimping on a cable, of its crimping fins; FIGS. 3A and 3B represent two cross sections of the crimping zone; FIG. crimping the contact of FIG. 2, one of these cuts being made at the level of the mechanical retention portion and the other of these cuts being made at the level of the electrical conduction portion; FIG. 4 is a diagrammatic perspective view of a crimping tool; - Figure 5 shows schematically in perspective a detail of the crimping tool of Figure 4; and FIG. 6 schematically shows in section a detail of the crimping tool of FIGS. 4 and 5. In these figures, the same references are used to designate identical or similar elements. [0029] Figure 1 shows an electrical contact 100 to be mounted in a connector cavity (not shown) of a motor vehicle. The contact 100 is made for example by stamping and bending a copper sheet. The thickness of this copper sheet is for example between 0.2 and 0.5 mm. In the case shown, it is a female contact 100, straight, extending in a longitudinal direction L which also corresponds to the coupling direction. In other cases not shown, the contact 100 may be a right angle contact, for example. The contact 100 is here shown attached to a carrier strip 101 whose contact 100 will be disconnected at a later stage, after possible tinning. The contact 100 has a coupling portion 110, a crimping zone 120 on the conductive strands 210 of a cable 200 and a crimping end 130 on the insulator 220 of this cable (see FIG. 2). . In the case shown in FIG. 1, the coupling portion 110, the crimping zone 120 and the crimping end 130 follow one another along the longitudinal direction L which also corresponds to the coupling direction. In the case of a right-angle contact, the coupling portion 110 may be perpendicular to the crimping zone 120 and the crimping end 130 which extend along the longitudinal direction L. But although the following description is directed to right contact, those skilled in the art will readily be able to transpose it for right angle or other contact. Before crimping, the crimping zone 120 is in the form of a gutter with two fins 122, 124 each extending on one side of a base 126. The two fins 122, 124 and the base 126 form therefore, before crimping, a groove 15 having substantially a U-shape in section in a plane perpendicular to the longitudinal direction L. Each fin 122 or 124 is continuous over its entire length. In other words, a fin 122 or 124 has no slot or cut. The contact 100 undergoes a crimping operation on a cable 200 during which the fins 122, 124 are folded and compressed on a stripped portion 20 cable 200. This crimping operation is performed by inserting the end of the cable 200 in the respective grooves of the crimping zone 120 and the crimping end 130 and striking the contact 100, at the crimping zone 120 between an anvil (not shown) of a type known to man of the profession and a punch 300 which will be described later. As shown in FIG. 2, after this crimping operation on the strands of the part of the cable 200 devoid of insulator 220, the crimping zone 120 has a mechanical retention portion 140, an electrical conduction portion 150 and a transition zone 160 between the two. The electrical conduction retention portions 140 and the transition zone 160 are in continuity with one another, without slits or cuts in the longitudinal direction L. [0034] The portions of FIG. mechanical retention 140 and electrical conduction 150 have different final crimping heights in a direction perpendicular to the longitudinal direction L and corresponding to the direction D of movement of the punch 300 to the anvil and vice versa. The final crimping height of the mechanical retention portion 140 (see also FIG. 3B) is lower than the final crimping height of the electrical conduction portion 150 (see also FIG. 3A). The heights of the mechanical retention portions 140 and electrical conduction 150 are essentially constant each along their respective lengths. The difference in height is therefore essentially fixed and can be between 10 0.5mm and 0.6mm, for a thickness of copper sheet between 0.20 and 0.39mm and for an aluminum cable whose diameter is included between 1.25 and 4 mm, or even between 0.75 and 6 mm. This difference in height is sufficient to obtain very different compression ratios respectively in the electrical conduction portion 150 and in the mechanical retention portion 140, while avoiding creating a crack or a tear in the sheet forming the contact 100. This is particularly important when the copper is tinned. Indeed, a tear or crack in the tinned copper layer would expose the underlying copper and therefore in the long term electrochemical corrosion phenomena mechanically weaken the contact and degrade its conduction, especially at the level of the copper. contact-cable interface. The compression ratio is defined as the ratio of the cable section 200 after crimping the cable section 200 before crimping. It can then be seen by comparing the cuts of the contact 100, and therefore the sections of the cable 200, respectively shown in FIGS. 3A and 3B, that the compression ratio of the cable 200 is higher at the level of the electrical conduction portion. 150 (FIG. 3B), at the level of the mechanical retention portion 140 (FIG. 3A). For example, to obtain a good electrical resistance between the contact and the cable, the compression ratio at the electrical conduction portion 150 is advantageously of the order of 50% or more (up to 65%) and the compression ratio at the mechanical retention portion 140 is between 20 and 30%. In the example described here, the length Ice (that is to say in the longitudinal direction L) of the electric conduction portion 150 is greater than 1.5 mm. It has been found by the inventors that with an ice length <1.4 mm, the electrical resistance of crimping is greater than 0.3 μm and changes over time, regardless of the compression ratio at the the electrical conduction portion 150. It has also been found by the inventors that with a compression ratio at the electrical conduction portion 150 less than 50%, the electrical resistance of the crimp is greater than 0.3 m and evolves in time, and this regardless of ice length. On the other hand, with an ice length> 1.4 mm and a compression ratio in the electrical conduction portion 150 greater than 50%, a resistance at the electrical conduction portion of less than 0.3 μm and stable in the electrical conduction portion is obtained. time. Returning to Figure 2, the size of the transition zone 160, in the longitudinal direction L, is between 0.3mm and 0.6mm. In this case, it is 0.3mm. The difference in height between the electrical conduction portion 150 and the mechanical retention portion 140 forms a step with an internal fold 162 and an outer fold 164. The inner folds 162 and outer 164 are rounded with a radius of curvature included between 0.1mm and 0.5mm. In the present case, the radius of curvature of the inner fold 162 is 0.1mm and that of the outer fold 164 is 0.2mm. In this case, the sum of the radii of curvature of the inner folds 162 and outer 164 is 0.3mm. The contact 100 illustrated in FIGS. 2, 3A and 3B is crimped using a tool comprising a punch 300 illustrated in FIGS. 4, 5 and 6. [0041] This punch 300 essentially has an elongated parallelepipedal plate shape. between a high end 310 and a low end 320, in the direction D of movement of the punch 300 during crimping (see Figure 4). This plate has a thickness E in the direction corresponding to the longitudinal direction L during crimping. The lower end 320 has two teeth 330 separated by a notch 340. As shown in FIG. 5, the notch 340 corresponds to the part of the punch 300 which makes it possible to shape the fins 122, 124, when crimping.
    [0002] The notch 340 has a V-shaped mouth 342 which enables the fins 122, 124 to be brought back to one another to a position in which they are substantially parallel, then to a channel 344, with essentially parallel walls. to receive the fins 122, 124 when they are parallel, and finally, a throat 346 which allows to gradually bring the fins 122, 124 successively above the cable 200, to it and finally in it. This groove 346 essentially has a W-shape in section in a plane perpendicular to the longitudinal direction L. The groove 346 has two successive segments 348, 350 in the longitudinal direction L. The deepest segment 348 corresponds to that which compresses the fins 122, 124 at the mechanical retention portion 140. The shallower segment 350 corresponds to that which compresses the fins 122, 124 at the electrical conduction portion 150. The difference in height h between these two segments can be between 0.5 and 0.6mm. In the example described here, this difference in height h is 0.55mm. The length of the segment 350 compressing the fins 122, 124 at the electrical conduction portion 150 has a dimension, in the longitudinal direction, greater than or equal to 1.4 mm. In the example described here, it is 1.5mm. The difference in height h between the segments 348, 350 forms a step with a step edge 352 and a step bottom 354. The step edge 352 may have a radius of curvature comprised for example between 0.1 mm and 0.5mm. In the case described here, it is 0.1mm. The bottom 354 of the step is also rounded. It may have a radius of curvature for example between 0.1mm and 0.5mm In the case described here, it is 0.2mm. Moreover, in order to avoid damaging the possible protective coating 25 (tin for example) of the contact, the edge 356 of the groove is also rounded with a radius of curvature for example between 0.15 and 0.4mm.
