Definitions

  • the box-like body inside which the one or more tabs protrude is generally made, together with the rest of the terminal, by folding a previously-stamped metal sheet.
  • Such a solution may not be capable of ensuring an optimal contact between the connection portion of the female terminal and the male terminal, since the lack of a join between the facing free edges allows the walls of the box-like body to which the free edges belong to bend outward; 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 entrain and bend the entire part of the box-like body from which they extend, with consequent deformations of the terminal and risk of its imperfect operation.
  • 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.
  • Another object of the present invention is therefore to provide a female terminal in which the parts of the box-like body are not subject to deformations that are such as to compromise the stability of contact.
  • Another object of the present invention is to provide a female terminal that can be easily produced in the manner of conventional female terminals.
  • the female terminal 10 comprises a crimping portion 11 and a boxlike connection body 12.
  • the boxlike connection body 12 comprises:
  • the fixing means 41 comprise a recess 43 and a corresponding tab 44 which is contoured to arrange itself in the recess 43, one being defined on either the first free edge 40 or the second free edge 42 and the other being defined on the remaining one of either the first free edge 40 or the second free edge 42, as can clearly be seen in Figures 3 and 4 .
  • the recess 43 is defined on the second free edge 42 and is open on the same side of the second free edge 42.
  • Corresponding extraction-preventing protrusions 45 and 46 extend toward each other from the opposite ends of the recess 43 and are adapted to prevent the exit of the tab 44, which protrudes from the first free edge 40, from the recess 43.
  • the tab 44 can be rapidly and easily interlocked in the recess 43, thus producing a structural stability of the box-like body 12 that is such as to prevent the contact pressure between the cantilevered contact tabs 18 and 19 and the male terminal from failing.
  • the tab 44 is fixed in the recess 43 by way of soldering spots or regions.
  • the female terminal 10 is also characterized in that it comprises a corresponding flexing limiting lamina, 21 and 22 respectively, for each one of the cantilevered contact tabs 18 and 19.
  • the flexing limiting laminas 21 and 22 extend from the same frame 17 until they affect the free end 23 and 24 of the respective cantilevered elastic tab 18 and 19, as can clearly be seen in Figure 1 .
  • the female terminal 10 comprises a front portion, which is the part where the male terminal is introduced into the connection body 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, visible in Figures 4 and 6 , within which a cantilevered bridge 31 extends which has an engagement protrusion 32 adapted to engage with a corresponding hole in the male terminal.
  • 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 10 is made in a single piece from stamped and folded metal sheet.
  • the optimal contact with the male terminal, stably, precisely and continuously, is also ensured 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 provided 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.
  • a female terminal has been provided that can be easily produced in the manner of conventional female terminals.
