Abstract
Abstract A cable termination block has terminals arranged in rows across the block, each terminal having a pin portion extending up from the top surface of the block and a socket portion in the bottom of the block. Incoming and outgoing cable conductors are attached to the pin portions, protectors plugging into the socket portions. The cable conductors are connected to alternating rows, i.e. incoming conductors to one row and outgoing conductors to the next row, and so on across the block. A dielectric member is positioned between adjacent rows of incoming and outgoing conductors. In one arrangement incoming conductors are attached to rows of long pins, outgoing conductors attached to rows of short pins. A dielectric member fits over the long pins and rests on the short pins. In another arrangement walls extend up from the block to separate adjacent rows of terminals. The walls may be inclined across the block to form tapered channels.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
A cable terminating block comprising; a rectangular block of dielectric material; a plurality of rows of terminals extending along the block from one end to the other, and a plurality of terminals in each row, the rows spaced to define spaces for cable conductors; each terminal including a terminal pin at one end extending from a top surface of said block and a terminal socket at the other end positioned within said block at a bottom surface thereof; each row of terminals consisting of alternating long terminal pins and short terminal pins; means at one end of said block for positioning conductors from a first cable for passage along said spaces and connection to the outer ends of said long terminal pins; means at the other end of said block for positioning conductors from a second cable for passage along said spaces and connection to said short terminal pins; a flat sheet-like dielectric member extending over said block and having rows of holes therein, a hole for each long terminal pin, the holes spaced to fit over said long terminal pins, the dielectric member resting on the short terminal pins, the conductors of said second cable extending below said dielectric member when connected to said short terminal pins and the conductors of said first cable extending above said dielectric member when connected to said long terminal pins.
Claim 2
Dependent Claim
227 words
A cable terminating block comprising; a rectangular block of dielectric material; a plurality of rows of terminals extending along the block from one end to the other, and a plurality of terminals in each row, the rows spaced to define spaces for cable conductors; each terminal including a terminal pin at one end extending from a top surface of said block and a terminal socket at the other end positioned within said block at a bottom surface thereof; each row of terminals consisting of alternating long terminal pins and short terminal pins; means at one end of said block for positioning conductors from a first cable for passage along said spaces and connection to the outer ends of said long terminal pins; means at the other end of said block for positioning conductors from a second cable for passage along said spaces and connection to said short terminal pins; a flat sheet-like dielectric member extending over said block and having rows of holes therein, a hole for each long terminal pin, the holes spaced to fit over said long terminal pins, the dielectric member resting on the short terminal pins, the conductors of said second cable extending below said dielectric member when connected to said short terminal pins and the conductors of said first cable extending above said dielectric member when connected to said long terminal pins.
Claim 3
Dependent Claim
83 words
A terminating block as claimed in claim 1, including: an incoming stub cable having a plurality of incoming conductors, said incoming conductors entering at one end of said block and connected sequentially to the outer ends of said long terminal pins of said rows of terminals; an outgoing stub cable having a plurality of outgoing conductors, said outgoing conductors entering at the other end of said block and connected sequentially to the ends of said short terminal pins of said rows of terminals.
Claim 4
Dependent Claim
46 words
A terminating block as claimed in claim 1, said means at one end and said means at the other end, of said block, comprising guide rings, the conductors from the cables being positioned in said guide rings when said conductors are connected to said terminal pins.
Claim 5
Dependent Claim
35 words
A terminating block as claimed in claim 3, including a snap-on cover for extending over said terminal pins, said cover snapping on at each end of said block, said cover engaging over said guide rings.
