The invention claimed is:
1. An electrical terminal comprising:
an electrically conductive wall having a first end and a second end;
an electrically conductive beam having a first end and a second end;
a pair of first shoulders flexibly coupling said first end of said beam to said first end of said wall; and
a tongue being flexibly coupled to said second end of said beam, said tongue extending generally toward said first end of said beam.
2. The electrical terminal of claim 1 further comprising:
a lead-in bend joining each of said shoulders of said beam to said wall.
3. The electrical terminal of claim 2 wherein said tongue protrudes beyond a plane defined by said shoulders opposite from said wall when in a nominal state thereof.
4. The electrical terminal of claim 3 further comprising:
a return stop located at said second end of said beam opposite from said first end of said beam, an edge of said return stop serving to abut against said wall to prevent over compression of said beam against said wall.
5. The electrical terminal of claim 2 further comprising:
a return leg flexibly joined to said second end of said beam opposite from said lead-in bends, said leg compressible against said wall for providing a shortened electrical path between said beam and said wall.
6. The electrical terminal of claim 5 further comprising:
an edge of said return leg pointing substantially toward said lead-in bends, a taper disposed along a lateral corner of said leg adjacent to said edge thereof.
7. The electrical terminal of claim 2 wherein said tongue is defined by a median portion, a recurved portion and a distal edge thereof, said distal edge of said tongue pointing substantially toward said wall.
8. The electrical terminal of claim 7 further comprising:
a tongue retainer joined to said wall between said lead-in bends, said tongue retainer covering said distal end of said tongue.
9. The electrical terminal of claim 1 further comprising:
a second beam;
a second wall; and
a second pair of outboard shoulders flexibly coupling said second beam to said second wall in substantially mirrored symmetry to said first beam and said first wall.
10. The electrical terminal of claim 9 wherein said walls define portions of a box terminal.
11. The electrical terminal of claim 10 further comprising:
a tail extending from said first wall opposite from said lead-in bends thereof, said tail having tabs projecting therefrom which are crimpably attachable to a conductive wire, said conductive wire supplying electrical current to said tail which in turn supplies electrical current to said wall and said beam.
12. The electrical terminal of claim 9 wherein forces required to insert a male member between said beams are reduced as said male member fully engages said pair of outboard shoulders and said tongue of each as compared to when said male member initially only engages said tongue of each.
13. The electrical terminal of claim 1 further comprising:
a locking formation projecting from said beam for engagement with an aperture within a male blade insertable against said beam.
14. An electrical terminal comprising:
first and second electrically conductive walls defining portions of a box terminal; and
a first electrically conductive beam flexibly coupled to said first wall, said beam having a pair of outboard shoulders and a tongue flexibly disposed therebetween, said tongue flexibly joined to said beam substantially opposite from where said beam is flexibly joined to said first wall, a lead-in bend joining each shoulder of said beam to said first wall, said tongue protruding beyond a plane defined by said shoulders opposite from said first wall when in a nominal state thereof, said tongue defined by a median portion, a recurved portion and a distal edge thereof, said distal edge of said tongue pointing substantially toward said first wall;
a second beam flexibly coupled to said second wall in substantially mirrored symmetry to said first beam and said first wall; and
a tail extending from said first wall opposite from said lead-in bend thereof, said tail having tabs projecting therefrom which are crimpably attachable to a conductive wire;
whereby forces required to insert a male member between said beams are reduced as said male member fully engages said pair of outboard shoulders and said tongue of each as compared to when said male member initially only engages said tongue of each.
15. An electrical terminal comprising:
an electrically conductive wall;
an electrically conductive beam flexibly coupled to said wall;
a lead-in bend flexibly joining said beam to said wall;
a return stop located at a distal end of said beam opposite from said lead-in bend, an edge of said return stop serving to abut against said wall to prevent over compression of said beam against said wall; and
a return leg flexibly joined to a distal end of said beam opposite from said lead-in bend, said leg compressible against said wall for providing a shortened electrical path between said beam and said wall.
16. The electrical terminal of claim 15 wherein said return stop is centrally disposed in a transverse direction providing transversely symmetrical loading of said beam.
17. The electrical terminal of claim 15 wherein there is a second return stop, said return stops being transversely disposed on either side of said beam.
18. An electrical terminal comprising:
an electrically conductive wall having a first end and a second end;
an electrically conductive beam having a first end and second end;
a pair of shoulders flexibly coupling said first end of said beam to said first end of said wall; and
a tongue being flexibly coupled to said second end of said beam, said tongue extending generally toward said first end of said beam,
wherein forces required to insert a male member against said beam are reduced as said male member fully engages said pair of shoulders and said tongue of said beam as compared to when said male member initially only engages said tongue.
