Definitions

  • the present invention relates to a female terminal for electrical connections.
  • connection portion has a box-like shape that comprises in turn, either inside or forming part of the walls of the box-like body, at least one cantilevered elastic contact tab, which is contoured to press against a male contact inserted into the box-like body of the connection portion.
  • Such female terminals usually have one or more cantilevered elastic contact tabs, which, because they are free to bend upon the passage of the male terminal, are not always capable of ensuring optimal contact with the male terminal; an example of this is a situation where the insertion of the male terminal along an unsuitable direction causes an excessive bending of the tabs to the point that they plastically deform at the bending point and are no longer capable of ensuring stable contact against the male terminal.
  • Another limitation of conventional female terminals is the fact that even if the male terminal is correctly inserted into the female terminal, the cantilevered contact tabs may not be capable of exerting a contact pressure such as to ensure a stable and constant contact even under conditions of knocks, vibrations or other, similar critical situations.
  • the aim of the present invention is to provide a female terminal for electrical connections that is capable of overcoming the above mentioned drawbacks of conventional female terminals.
  • an object of the present invention is to provide a female terminal that is always capable of ensuring an optimal contact with the male terminal, stably, precisely and continuously.
  • Another object of the present invention is therefore to provide a female terminal in which the cantilevered contact tabs are not subject to permanent plastic deformation that compromises their correct elasticity.
  • Another object of the present invention is to provide a female terminal that can be easily produced in the manner of conventional female terminals.
  • a female terminal for electrical connections according to the invention is generally designated with the reference numeral 10.
  • the female terminal 10 is of the type comprising a crimping portion 11, for connecting an electric wire, and a connection portion 12.
  • connection portion 12 comprises:
  • the female terminal 10 comprises a front portion, which is the part where the male terminal is introduced into the connection portion 12, and a rear portion, which is the crimping portion 11.
  • the female terminal 10 has two laterally adjacent cantilevered tabs 18 and 19 which extend from a front portion 25 of the frame 17 of the cover 16.
  • the flexing limiting laminas 21 and 22 are each constituted by a flat tab that extends from the rear portion 26 of the frame 17 and is folded in a U-shape toward the center of the cover 16.
  • connection portion 12 has a central opening 30 within which a cantilevered bridge 31 extends which has an engagement protrusion 32 adapted to engage with a corresponding hole in the male terminal; these details are clearly visible in Figures 4, 5 and 6 .
  • the cantilevered contact tabs 18 and 19 are arc-shaped, with the concavity directed outward.
  • these tabs In the central region these tabs have a longitudinal contact ridge 33 and 34 respectively, which extends into the interspace 20.
  • the female terminal 110 has two laterally adjacent cantilevered tabs 118 and 119, a first one 118 of which extends from the rear portion 126 of the frame 117 of the cover 116, and the second 119 from the front portion 125.
  • a first one 121 of the flexing limiting laminas 121 and 122 extends from the front portion 125 of the frame 117, and the second 122 from the rear portion 126.
  • the female terminal 210 has two laterally adjacent cantilevered tabs 218 and 219 which extend from a rear portion 226 of the frame 217 of the cover 216, while the flexing limiting laminas 221 and 222 extend from the front portion 225 of the frame 217 proper.
  • the female terminal 10, 110 and 210 is made in a single piece from stamped and folded metal sheet.
  • a female terminal has been devised that is always capable of ensuring an optimal contact with the male terminal, stably, precisely and continuously, by virtue of the flexing limiting laminas which prevent the cantilevered contact tabs from flexing outward excessively, retaining them stably against the inserted male terminal.
  • a female terminal has been devised in which the cantilevered contact tabs are not subject to permanent plastic deformation that compromises their correct elasticity, since the contact tabs are not permitted to bend to the extent that yielding is induced, even in the event of incorrect insertion of the male terminal along a direction that could damage the tabs.
