Definitions

  • the present invention relates to a female electrical terminal with soft coupling.
  • a conventional soft-coupling female electrical terminal comprises a flat metal body, usually obtained from blanked and stamped plate, that is connected at one end to pairs of foldable clamping flaps for an electrical wire.
  • the clamping portion is aligned to the body or lies at right angles thereto.
  • the body is laterally provided with two longitudinal wings that are folded so as to form a semitubular profile and provide, together with said body, an electrical contact seat for the flat strip of a male terminal.
  • the body is furthermore transversely crossed by slots which form, between them, flexible regions, from at least one whereof a stud protrudes, towards the electrical contact seat, that is accommodated in a corresponding hole of the strip of the male terminal.
  • a principal aim of the present invention is to provide a new soft-coupling female terminal that truly achieves a reduction in the load to be applied for coupling to the male terminal without changing the applicable current load.
  • an object of the present invention is to provide a female terminal that can be subjected to a large number of insertions and disengagements without compromising the electrical contacts.
  • Another object is to provide a female terminal that can be mass-manufactured with conventional equipment and facilities.
  • a female electrical terminal comprising a flat metal body, obtained from blanked and stamped plate, that is connected at one end to pairs of foldable clamping flaps for an electrical wire and is laterally provided with two longitudinal wings that are folded so as to assume a substantially semitubular shape and form, together with said body, an electrical contact seat for the flat strip of a male terminal, said female terminal being characterized in that said body is longitudinally crossed by two slots which form, between them, a flexible region that is provided with a stud protruding towards the electrical contact seat.
  • a female electrical terminal in a first embodiment, comprises a flat metal body 10, obtained from blanked and stamped plate, which is connected at one end to a tab 11 from which two pairs of foldable flaps, respectively 12 and 13, protrude for accordingly clamping an electrical wire, not shown in the figures, the stripped end whereof is appropriately placed between said flaps so as to rest on the tab 11.
  • the metal body 10 is laterally provided with two longitudinal wings 14 that are folded so as to assume a substantially semitubular shape and form, together with said body 10, an electrical contact seat 16 for the flat strip of a known male terminal, which is not shown.
  • the body 10 is longitudinally crossed by two parallel slots 17 which form, between them, a flexible region 18 that is provided with a stud 19 that protrudes towards the electrical contact seat 16.
  • the slots 17 are substantially crescent-shaped and the stud 19 has a substantially triangular longitudinal profile, with the higher region on the opposite side with respect to the one where the male terminal is inserted.
  • the region 18 is wider and higher in the median region than at the lateral ends.
  • the two longitudinal wings 14 have lateral studs 20 that protrude towards the electrical contact seat and are adapted in particular to reduce the lateral play between the male terminal and said female terminal once insertion has occurred.
  • a female electrical terminal according to the invention in a second embodiment, is generally designated by the reference numeral 100.
  • the terminal 100 is of the L-shaped type and is different from the terminal related to the first embodiment, to which reference is made for a detailed description of the clamping flaps and of the body with the corresponding electrical connection seat, in that said clamping flaps, generally designated by the reference numeral 101, are arranged at right angles to the body, designated by the reference numeral 102.
  • the provision of the slots 17 in a longitudinal direction has in fact allowed to extend the elastic region and thus reduce the pressure required to perform the movement of the stud 19 which, when the male terminal is inserted, must move downwards before entering the corresponding seat of said male terminal.
  • the materials employed may be any according to the requirements.
