not in its fully inserted position in plug receiving cavity 40 39 when the plug 60 39 is fully inserted the aligned contact terminals 78c 39 and 78f 39 not shown will urge associated spring contact portions 76c 39 and 76f 39 out of contact with fingers 86 39 and 88 39 respectively referring now to fig9 there is illustrated an alternate embodiment of the present invention wherein the major difference when compared with the first embodiment is that the plug receiving cavities 140 and 140 39 of fig9 are constructed in a 34 mirror image 34 relationship with respect to a plane extending transversely through the mid portion 164 of the housing 112 in this construction the orientation of plug 60 is reversed from the embodiment of fig6 this results in a signal position transposition between the signals on contact terminals 78 of plug 60 and contact terminals 78 39 of plug 60 39 as illustrated in fig9 this means that the signal on the fourth contact terminal 78d 39 of plug 60 39 will be transmitted along conductor 170 to the fifth contact terminal 78e of plug 60 similarly a signal on the first contact terminal not shown of plug 60 39 will be transposed to the eighth contact terminal not shown of plug 60 a signal on the second contact terminal of plug 60 39 will be transposed to the seventh contact terminal of plug 60 et cetera in this embodiment the aligned apertures in barrier walls 149 149 39 are positioned slightly off center from their position illustrated in fig6 further in the embodiment of fig9 a stamped and formed conductor 170 is utilized which includes a central portion 172 intermediate portions 174 174 39 and spring contact portions 176 176 39.
