The fastening device 42 is positioned about the lug 46 within the cavity 28 when the terminal connector 14 and terminal block 12 are brought together to form the assembly as best shown in FIGS. 2 and 3.
- the lug 46 is stamped to form bumps or projections 60 on one, the bottom, side of the lug 46.
- the projections 60 define a gripping means for engaging and gripping a wire conductor.
- the bottom wall 62 of the collar 52 is also stamped to form grooves 64 which cooperate and mate with the projections 60 on the lug in gripping and holding a wire conductor to the terminal connector 14.
- the projections 60 are aligned with the grooves 64 so that, when a wire conductor is received within the collar 52 and the fastener 54 is threaded into the collar 52, the projections 60 will press into the wire conductor in an area above the grooves 64 and any displacement of the wire conductor by reason of the pressure applied thereto by the projections 60, will be displaced into the grooves 64.
- the projections 60 and the grooves 64 form a gripping means for establishing a firm and strong connection between the lug 46, the collar 52 and the wire conductor received between the lug 46 and the collar 52.
- the collar 52 is formed from a strip of metal which is folded over into the shape shown in FIG. 4. It is to be understood that the collar can be formed from a single piece of metal and can be, for example, an extruded part.
- each of the terminal strips 41 is received in one of the recesses 34, while at the same time the blades 44a-c of each strip 41 are received in the slots 26a-c communicating with one of the apertures 24.

It will be apparent from FIG. 5 that one group of four slots 126a-d is associated with each group of apertures 124a-4. As a result, in this second embodiment of the terminal block of the present invention each slot 126a, b, c, or d extending into the terminal block 112 from the bottom side thereof opens into a single aperture 124a, b, c, or d.
- the top side 123 is a planar surface without a shoulder formed thereon so that the portion of the top side 1233 onto which openings 133 open is not offset or otherwise separated from the portion of the top side 123 onto whichthe apertures 124a-d open.
- the terminal connector 1 14 which is received within the terminal block 112 includes a terminal strip 141 and a fastening device 142.
- the terminal connector 114 differs somewhat from the terminal connector 14 shown in FIG. 4 in that the terminal strip 142 has a slightly longer base 143 from which four terminal blades 144a-d extend. Also, the terminal strip 142 has a lug 146 which is offset a shorter distance from the base 143, than is the lug 46 from the base 43, and is connected to the base 143 by an inclined connecting portion 148.
