62a 39 for insertion into a corresponding pair of appropriate holes in printed circuit board 42 these multiple tails of the ground terminal provide multiple grounding paths to reduce the impedance of the system the multiple tails also provide an improved ground termination to the pc board and thereby are capable of enhancing the shielding effect fig7 shows a further improvement wherein the ground terminal not only has a pair of tail portions 62a 39 but also a pair of contact portions 62b 39 projecting into aperture 22a of cylindrical boss 22 of the dielectric housing for engaging terminal portion 66 of the coaxial plug the contact portions 62b 39 increase the surface contact area between the ground terminal and the plug ground terminal portion again reducing the impedance of the system fig8 shows an embodiment wherein contact portion 62b of ground terminal 62 is extended and wrapped about the outside of cylindrical boss 22 of the housing with a distal end 62c of the ground terminal in engagement with front wall 24 of shield 20 therefore the coaxial plug not only has a ground path to the printed circuit board directly through ground terminal 62 but the ground terminal in turn is coupled to the ground plane of the printed circuit board through the shield and its grounding legs 38a fig1 and 2 fig9 shows an.
