Abstract

A ribbon crossover cable assembly (10) and method provides for longitudinally splitting a first ribbon cable (12) between a centrally located pair (22) of conductors (14) through a limited segment (24) of the first ribbon cable (12) thereby forming an opening (26). The first end (18) of the first ribbon cable (12) is passed through the opening (26) such that the first end (18) of the first ribbon cable (12) is looped through opening (26). An end (30) of a second ribbon cable (28) is passed through the opening (26) and connectors (34,36) are terminated to the ends (18,30;20,32) of the cables (12,28).

Claims

1. A ribbon crossover cable assembly, comprising:

a first ribbon cable, said first ribbon cable having conductors surrounded by insulation, first and second ends and an opening formed by a separation through a limited segment of said first ribbon cable between a centrally located pair of conductors, said first ribbon cable having said first end passed through the opening such that said first end is looped through said ribbon cable;

a second ribbon cable, said second ribbon cable having conductors surrounded by insulation and second ends, said first end passing through the opening in the first cable;

a first connector having contacts, said contacts terminated to respective ones of the conductors of the first and second cables at the first ends thereof; and

a second connector having contacts, said contacts terminated to respective ones of the conductors of the first and second cables at the second ends thereof.

2. A ribbon crossover cable assembly as recited in claim 1, wherein the first and second cables have the same number of conductors.

3. A ribbon crossover cable assembly as recited in claim 1, wherein the contacts in said second connector are electrically commoned with respective ones of the contacts in the first connector.

4. A ribbon crossover cable assembly as recited in claim 1, wherein the first connector has the same number of contacts as the second connector.

5. A method of producing a ribbon crossover cable assembly, comprising the steps of:

longitudinally separating conductors of a first ribbon cable through a limited segment of the first ribbon cable between a centrally located pair of conductors forming an opening;

passing a first end of the first ribbon cable through the opening such that the first end of the ribbon cable is looped through the ribbon cable; and

passing an end of a second ribbon cable through the opening.

6. A method as recited in claim 5, further comprising the step of terminating respective ends of the first and second cables to connectors.

7. A method as recited in claim 6, wherein the step of terminating respective ends of the first and second cables to connectors comprises:

terminating the first ends of the first and second cables to a first connector; and

terminating the second ends of the first and second cables to a second connector.

8. A method of producing a ribbon crossover cable assembly, comprising the steps of:

longitudinally separating conductors of a first cable from a first end through a portion of its length, defining first and second segments in said first cable;

longitudinally separating a second cable from a first end through a portion of its length, defining first and second segments in said second cable;

longitudinally separating conductors of the first and second segments of the first ribbon cable through a limited segment of the first ribbon cable between a respective centrally located pair of conductors forming respective openings therein;

passing the first end or respective first and second segments through respective openings therein such that the first end of each segment passes through the respective opening in each segment; and

passing a respective first end of the first and second segments of the second cable through respective openings in the first cable.

9. A method as recited in claim 8 further comprising the step of terminating respective ends of the first and second cables to connectors.
