side of the plug body 10 and a groove 44 extends across the opposite side of the plug body 10 the ground conductor 40c extends from the attachment body 12 into a portion of the groove 44 and passes into the plug body 10 at the pivot axis 16 the ground conductor 40c is then physically attached to the ground pin 26 via crimping soldering or the like fig3 and 31 illustrate variations in the connections between the conductive pins 18a 18b 26 and the conductors 40a 40b 40c of wire 40 in each of these variations the ground conductor 40c extends through the attachment body 12 along one of the conductors 40a or 40b and passes into the plug body 10 along with the respective conductor coaxially with the pivot axis 16 so as to enable smooth pivoting of the plug body 10 relative to the attachment body 12 and at the same time to minimize the potential damage of the electrical conductors due to the pivoting motion in fig3 and 31 the attachment body 12 has not been illustrated for the purposes of clarity but it is to be understood that the physical structure of the attachment body 12 the plug body 10 and their connecting relationships are the same as previously described in relation to the third embodiment illustrated in fig2 29 except for the groove 44 formed in the plug body 10 in the variations illustrated in fig3 and 31 since the ground conductor 40c passes through the attachment body 12 and into the plug body 10 along the pivot axis 16 groove 44 in the plug body 10 is not necessary in fig3 the ground conductor 40c.
