A flat cable system includes at least three types of insulated cables with flat conductors, the conductor spacing being either a distance D or a multiple thereof. A connector block for electrically connecting the cables to each other or to wires leading to outside devices includes upper and lower plastic blocks, the lower block having recess with internally threaded backing nuts therein in a staggered pattern, the nuts being spaced by distances D. The upper block carries a puncturing member, a threaded bolt, a spring washer and a terminal connected to a wire. The bolt has a drill point to penetrate one or more cables and threadedly engage one of the backing nuts, forming a clamp assembly which forces the puncturing member into electrical contact with the conductor. An intermediate board for interconnecting plural cables is disclosed.

An apparatus for making electrical connections to a flat cable of the type having a plurality of flat conductors lying in substantially the same plane in parallel, spaced relationship and covered by insulating material, the apparatus comprising a first body of dielectric material having a first surface; a plurality of backing members carried by said first body, each of said backing members having a surface adjacent to and facing in the same direction as said first surface and having an internally threaded hole therein; a second body of dielectric material having generally parallel second and third surfaces; a plurality of puncturing members carried by said second body, each of said puncturing members having at one end thereof a toothed edge extendable beyond said second surface and having a driving edge at the other end thereof adjacent said third surface; a plurality of elongated bolts, each of said bolts being dimensioned to extend through said second body and one of said puncturing members and including an enlarged head at one end, external threads at the other end dimensioned to threadedly engage the threads in one of said backing members, means defining a point at said threaded end for penetrating one of said flat conductors, and a non-threaded portion for receiving a wire connector; and spring washer means surrounding said non-threaded portion for exerting pressure against said driving edge of said one of said puncturing members, whereby said first and second bodies can be assembled with the flat cable between said first and second surfaces and with each of said bolts penetrating one of said conductors so that the threaded end thereof is threaded into one of said backing members and so that said bolt head acts through said washer means to press said toothed edge through one surface of the cable insulating material into electrical contact with one of said conductors, the other surface of said cable being held against one of said backing members.
