- the difference between the depth anvil groove P3 of the first anvil member 51 and the anvil throat depth P4 of the second anvil member 53 forms a rising anvil step 90 from the groove 85 of the first anvil member 51 to the groove 86 of the second anvil member 51.

- the crimping heights H1, H2 therefore affect the crimping zone 14 of the electrical contact 10 after the crimping operation. They are measured between the bottom of the crimping drum 22 and the point of intersection of the crimping fins 18, bent over the conductive strands 32.
- the crimping height H2 of the second crimping element 43 is less than 10% to 60% of the crimping height H1 of the first crimping element 41, preferably 30%> to 50% lower.
- Figure 8 shows a perspective view of the electrical contact 10 of Figure 1 for which the coupling portion 12 has not been shown to facilitate the description of this figure.
- the electrical contact 10 is shown crimped with the conductive strands 32 of the cable 30 after a crimping operation performed with the tool 40 described through Figures 2 to 7.
- the crimping zone 14 of the electrical contact 10 has a mechanical retention portion 92, an electrical conduction portion 94 and a transition zone 96 between the two .
- the portions of mechanical retention 92, electrical conduction 94 and the transition zone 96 are continuous material with each other, without slit or cut in the longitudinal direction L.
- the mechanical retention portion 92 is the portion which has been crimped by the first crimping element 41.
- the mechanical retention portion 92 is the portion of the fins 18, 20 and the crimping barrel 22 having been crimped onto the strands. conductors 32 by the first crimping element 41.
- the mechanical retention portion 92 is the portion adjacent to the insulation of the cable 34.
- the electric conduction portion 94 is the portion which has been crimped by the second crimping element 43.
- the electrical conduction portion 94 is the portion of the fins 18, 20 and crimping sleeve 22 having been crimped onto the strands. conductors 32 by the second crimping element 43.
- the electrical conduction portion 94 is the portion adjacent to the coupling portion 12.
- the portions of mechanical retention 92 and electrical conduction 94 have lengths along the longitudinal axis L preferably similar.
- the portions of mechanical retention 92 and electrical conduction 94 have their crimping heights H1, H2 different along the vertical axis V.
- the crimping height H 1 of the mechanical retention portion 92 is less than the crimping height H2 of the electrical conduction portion 94.
- the difference in height H1-H2 between the mechanical retention portion 92 and the electrical conduction portion 94 forms the transition zone 96.
- This transition zone 96 has the particularity of comprising two steps 101, 102: a downward movement of the contact 101 in the vertical direction perpendicular to the longitudinal axis L from the folded portion of the fins 18, 20 the mechanical retention portion 92 to the folded portion of the fins 18, 20 of the electric conduction portion 94; and a rising step 102 of the contact in the vertical direction perpendicular to the longitudinal axis L from the portion of the barrel 22 of the mechanical retention portion 92 to the portion of the barrel 22 of the electric conduction portion 94.
- These two contact steps 101, 102 have been formed during the crimping process by the crimping tool 40 comprising a rising anvil step 90 and a downward punching step 75.
- the two contact steps 101, 102 are generally aligned along the vertical axis V perpendicular to the longitudinal axis L.
- the crimping heights H 1, H 2 of the mechanical retention portions 92 and electrical conduction portions 94 are essentially constant each along their respective lengths.
- the difference in height H1-H2 may be of the order of 0.1 to 0.7 mm.
- the difference in height is therefore essentially fixed and can be between 0.5 mm and 0.6 mm, for a thickness of copper sheet between 0.20 and 0.39 mm and for a cable aluminum whose diameter is between 1.25 and 4 mm, or even between 0.75 and 6 mm.
- the difference in crimping height H1-H2 between the mechanical retention portion 92 and the electric conduction portion 94 is distributed between the height of the rising step 102 of the contact and the downward travel 101 of the contact.
- the upward travel 102 is between 0.4 times and 1.6 times the height of the downward travel 101, preferably between 0.8 times and 1.2 times.
- This ratio between the height of the rising contact step 102 and the downward contact step 101 is important in order to guarantee at best a correct folding between the two fins 18, 20 on the conductive strands 32, that is to say one folding the fins 18, 20 by the crimping tool 40 giving them a sectional shape in a plane perpendicular to the longitudinal direction L of two arches joined side by side by one of their free end.
- This two-step solution 101, 102 makes it possible to guarantee the correct folding of the fins 18, 20 despite a non-zero tolerance clearance between the alignment along a transverse axis T of the punch elements 62, 64 with the anvil elements 51, 53.
- misalignment of the anvil members 51, 53 with the punch members 62, 64 may result in folding of the wings 18, 20 for which a free end of a folded fins 18 bears against the other folded fin 20.
- a high risk of galvanic corrosion between the copper contact 10 and the conductive strands 32 of aluminum may appear and thus deteriorate the electrical conduction between the electrical contact 10 and the conductive strands 32.
- the electric conduction portion 94 compresses the free end of the conductive strands 32, while the mechanical retention portion compresses the portion of the conductive strands 32 adjacent to the insulator of the cable 34.
- the compression ratio is defined as the ratio of the section of the cable after crimping on the section of the cable before crimping SI. It can then be seen, by comparing the section of the contact, and therefore the sections of the cable shown in FIG. 9, that the compression ratio of the cable is higher at the level of the electrical conduction portion 94 than at the level of the portion of mechanical retention 92.
- the compression ratio S3 / S1 at the level of the electrical conduction portion 94 is between 45% to 65%, preferably between 50% and 60% and the compression ratio S2 / S1 at the mechanical retention portion 92 is between 15% to 40%, preferably between 20% and 30%.
- the compression of the free end of the conductive strands 32 that is to say the reduction of its section SI, is effected by compressing the folded portion of the fins 18, 20 of the portion of electrical conduction 94 and by the compression of the portion of the barrel 22 of the electric conduction portion 94 on the free end of the conductive strands 32.
- the reduction of section SI of the free end of the conductive strands 32 is distributed according to a reduction obtained by a crimping height H2 of the electrical conduction portion 94 greater than the crimping height H1 of the mechanical retention portion 92 causing the formation of the rising contact step 102 and the downward movement of contact 101.
