each include a rearwardly extending shaft portion 20 that extends through appropriately placed holes 22 24 in the panel 11 and therebehind into cavities 25 in the the main body 13 these shafts 20 rotate about their own longitudinal axis and are captivated in the main body 13 by the protruding piercing point portions 26 of a plurality of terminal means shown in fig2 as terminals 28a 28b and 28c although not visible in fig2 there are also three corresponding but inverted terminal means 28d 28f carried on the opposite side of the main body and rearwardly of terminals 28a 28c each and all of these terminals being referred to generally as terminals 28 one of these terminals 28 is shown enlarged in perspective view in fig3 it consists essentially of a rectangular piece of thin conductive metal having a central portion 26 struck outwardly at a right angle from its center portion 26 also defining in part a pair of piercing points 29 terminal 28 also has a hole 32 therethrough which is used in conjunction with one of three tapped holes 34 36 in the main body 13 see fig4 each of the terminals 28 is fixedly mounted to the main body 13 by means of a screw 38 which extends through the terminal 39 s hole 32 and into a tapped hole 34 36 each of the screws 38 is intended to also function to receive under its head the stripped end of a conductor not shown to which one of the conductors within cable 12 is ultimately electrically connected each of the terminals.
