Definitions

  • the present invention relates to a method for producing lead terminals or the like on cables made of aluminum or alloy with a high aluminum content.
  • the invention relates, more particularly, to the connection lugs for accumulator batteries such as those with which motor vehicles are fitted.
  • One of the aims of the present invention is to carry out a method which remedies the various aforementioned drawbacks.
  • the method according to the invention aims to produce lead or lead alloy terminals on cables comprising an insulating sheath and an aluminum core and in which one fixes on the core, after having stripped a corresponding length a metallic element and the lug is molded on said metallic element, said method being characterized in that a metallic element is used which is externally compatible with lead or lead alloy forming the terminal and internally compatible with the aluminum core without formation of a high resistivity compound.
  • An advantage of such a process is that it does not significantly modify the usual techniques of lead overmolding on cables.
  • an aluminum element with an aluminum alloy is used, the external surface of which is coated with a thin layer of nickel, itself coated with a thin layer of lead.
  • a copper, copper alloy or brass element is used, the surface of which ex dull is coated with a thin layer of lead or lead tin.
  • an aluminum or aluminum alloy element is used, the external surface of which is coated with a thin layer of lead tin.
  • an element made of aluminum or aluminum alloy is used, the external surface of which is coppery or tanned.
  • the terminal is molded so that it includes part of the end of the insulating sheath.
  • the invention also relates to a terminal for connecting accumulator batteries as defined above.
  • the reference 1 designates a cable 1 comprising an insulating sheath 2 and an aluminum strand 3.
  • the end of the cable 1 is stripped in order to expose a corresponding length of the core or of the strand 3.
  • an aluminum element 4 is engaged, the latter on its external surface being coated with a very light layer of nickel 5 of the order of 0.5 to 15 ⁇ m on which is electrolytically deposited, by dipping, or under vacuum and or by spray evaporation of lead 6 or a lead tin alloy.
  • the element 4 in the example shown takes the form of a socket with a bottom 4a and a side skirt 4b, but it could be constituted by a tubular element, a part with a U-section or the like.
  • the element 4 is fixed to the strand 3 by punching, crimping, magneto forming or compression stretching. In the example shown, a crimping operation was carried out in order to ensure the connection between the strand 3 and the sleeve 4.
  • the end of the cable 1 with its sleeve 4 is placed in a mold 8 with two assemblable parts and in which the lead terminal 9 is directly molded. As can be seen in FIG. 4, the molding is carried out so that the end of the sheath 2 adjacent to the stripped part is included in the terminal 9.
  • the cable 11 comprises an aluminum strand 12 and an insulating sheath 14.
  • the stripped part of the cable is housed in an element 13 made of copper, copper alloy or brass, the outer surface of which is coated with a thin layer of lead or lead tin 15.
  • the element 13 is fixed by the usual means on the strand and the terminal is molded as shown in FIG. 4.
  • FIG. 6 shows an alternative embodiment in which the cable 17 comprises a sheath 18 and an aluminum strand 19.
  • the stripped part is housed in an element 21 made of aluminum or aluminum alloy coated with a thin layer of lead tin 20.
  • the element 21 can be fixed by any means to the strand 19 as specified in the first embodiment, said element 21 then receiving the lug molded, as shown and described in FIG. 4.
  • FIG. 7 shows a last embodiment of the invention in which the element 25 is made of aluminum or aluminum alloy, its outer surface being coated with an under layer 26 such as copper plating or tanning 26.
  • the cable 22 comprises a sheath 23 with an aluminum strand 24.
  • the element 25 is, as in the various previous embodiments attached to the strand 24 and receives molded the terminal.
