  • the planar mounting portion 90 of the terminal 60 is first aligned with the opening 44, in particular the planar mounting portion 90 is inserted into the opening 44 and upon further insertion is aligned or guided into the slots 48 by the curved or ramped projections 46, As best shown in FIGS. 11 and 12 the opening 44 is also configured so that a diagonal distance across the opening 44 or the largest possible distance across the opening 44 is less than the entire width Wl of the planar mounting portion 90 of the terminal 60. As further illustrated in FIG.
  • the diagonal distance across the opening 44 is shown as Ul and U2; in both instances Ul and U2 are less than width Wl of the mounting portion 90, In this case, the edges of the planar mounting portion 90 will engage or abut the housing 40 and cannot be inserted into the cavity 40 in a wrong or misaligned position and thereby reducing the possibility for terminal damage.
  • the ramped projection 46 in the housing 22 engages the arc shaped contacting portion 92 so as to create a pre-load or bias therefore providing a force to the terminal 60 in a downward or second direction D.
  • This bias keeps the flat planar mounting portion 90 and flat planar main body portion 62 of the terminal 60 in constant contact with the bottom surface of the slot 48.
  • the ramped projection 46 also includes a flat portion 47 with a longitudinal recess 49 formed in the middle portion of the projection 46, whereby the recess 49 eliminates contact with the middle or central portion of the arc shaped contacting area 92, As best shown in FIG 10, the projection 46 only makes contact with the contacting portion 92 of the terminal 60 only on the outer areas or edges of the arc shaped contacting portion 92 therefore minimizing contact between the terminal 60 and the ramped projection 46 and thereby reducing wear and damage to the terminal plating in the area of electrical contact.
  • the locking tang 86 extending from the main body portion 62 engages the projection 52 in the bottom surface of the cavity 40.
  • the ramped end 54 of the projection 52 engages the tang 86 and forces the tang 86 upward as the terminal 60 is advanced in the cavity 40,
  • the tang 86 rides over the projection 52 to the point where the tang 86 snaps back into its original position behind the shoulder 56 of the projection 52 so that the trailing or back edge of the tang 86 engages the shoulder 56 and locks the terminal 60 in the cavity 40.
  • the planar mounting portion 90 of the terminal 60 resides in a front portion 24 of the cavity slot 48 but does not extend to the end of the slot 48.
  • a space S exists between the front edge of the planar mounting portion 90 of the terminal 60 and the stop or end surface 50 of the slot 48 allowing for the planar mounting portion 90 to translate along a mating direction A within the slot 48.
  • the bent arc portion 92 of the electrical terminal 60 extends through the window 42 formed in the terminal receiving portion 32 facing the opening 30 in the connector housing 22, Upon mating of the first and second connectors 20, 20', the terminal receiving portion 32 of the first connector 20 is received in the opening 30' of the second connector 20' and similarly the terminal receiving portion 32' of the second connector 20' is received in the opening 30 of the first connector 20.
  • respective arc shaped contacting portions 92 of the electrical terminals 60 protruding out of windows 42 of each of the connector housings 22 respectively engage each other. With the respective engagement of the mating terminals 60, the bent arc portions 92 are deflected upon mutual engagement and tend to flatten out. This causes the planar mounting portion 90 of each electrical terminal 60 to translate in the slot 48 allowing for proper electrical engagement between the terminals 60.
  • the electrical terminal 60 of the alternate embodiment includes a pair of aligning ribs 70 formed from the main body portion 62 of the terminal 60 as best illustrated in FIG. 15.
