8 . The electrical terminal of claim 7 , further comprising an opening through the top wall, the opening at least partially aligning with the space.
9 . The electrical terminal of claim 7 , wherein a rear end of the rear section of the polarization rib is spaced rearwardly from the rear end of the body of the hood, and further comprising a rear flap extending from a rear end of the rear section and at an angle relative to the planar top wall, wherein a free end of the rear flap is proximate to the top wall.
10 . The electrical terminal of claim 7 , further comprising a front lock projection extending upward from the top wall, and wherein the front section of the polarization rib has a front lock recess provided in a lower surface thereof, the front lock projection seating within the front lock recess, and a rear lock projection extending upward from the top wall, and wherein the rear section of the polarization rib has a rear lock recess provided in a lower surface thereof, the rear lock projection seating within the rear lock recess.
11 . The electrical terminal of claim 1 , wherein
the body of the contact defines a contact portion, and the contact further includes a wire securing portion extending from the rear end of the contact portion and which is configured to connect to exposed conductors of a lead wire and to connect to insulation of the lead wire, and
the hood partially surrounds the contact portion, with the front end of the hood being forward of the front end of the contact portion, wherein a first length is defined between the opposite front and rear ends of the hood; and
further comprising a connector assembly comprising a housing, a seal and a seal cover, the housing being disposed forward of the seal and the seal cover being disposed rearward of the seal, wherein a second length is defined between front and rear ends of the seal, the first length being a minimum of 1.1 times the second length.
12 . The electrical terminal of claim 1 , further comprising curved flanges extending from the front end of the body of the hood.
13 . The electrical terminal of claim 1 , wherein e contact further comprises a wire securing portion configured to connect to exposed conductors of a lead wire and to connect to insulation of the lead wire.
14 . The electrical terminal of claim 13 in combination with a connector assembly, comprising a housing, a seal and a seal cover, the housing being disposed forward of the seal and the seal cover being disposed rearward of the seal, wherein a first length is defined by a portion of the hood that overlays the contact, and a second length is defined between front and rear ends of the seal, the first length being a minimum of 1.1 times the second length.
15 . The electrical terminal of claim 1 , further comprising an indentation formed in a wall of the body of the contact opposite from the wall from which the deflectable contact beam extends, the indentation extending into the passageway of the contact, the deflectable contact beam and the indentation aligning with each other.
16 . The electrical terminal of claim 15 , further comprising a deflectable stiffening beam extending from a wall of the hood, wherein the contact beam is configured to contact the stiffening beam.
17 . An electrical terminal comprising:
