Abstract

A positive retention system for individual cable assemblies provides positive restraint for a variety of sizes, styles, and shapes of flat, discrete, twisted pair, and tri-lead wire cable assemblies used in card-on-board electronic packages. The system holds cables in place without applying a force to the board, and is applied manually, without the use of tools. The system may be applied to any or all of the cable positions of a typical board assembly. The hardware is designed such that it provides the least restriction to air flow in order to obtain maximum cooling. As shown in the drawing the mechanism is comprised of five parts: a return spring 11, a retaining clip 12, a double row cable yoke 13, a support yoke 14, and a carrier 15.

Positive Retention System for Individual Cable Assemblies

A positive retention system for individual cable assemblies provides positive restraint for a variety of sizes, styles, and shapes of flat, discrete, twisted pair, and tri-lead wire cable assemblies used in card-on-board electronic packages. The system holds cables in place without applying a force to the board, and is applied manually, without the use of tools. The system may be applied to any or all of the cable positions of a typical board assembly. The hardware is designed such that it provides the least restriction to air flow in order to obtain maximum cooling. As shown in the drawing the mechanism is comprised of five parts: a return spring 11, a retaining clip 12, a double row cable yoke 13, a support yoke 14, and a carrier 15. After selecting the cable positions where retention is required, the mechanism is assembled, by hand, by inserting the retaining clip 12 into the carrier 15 until the square hole of the retaining clip 12 and the square hole 16 of the carrier 15 align. Then the double row yoke 13 is slid into the support yoke 14, and this assembly is passed into the square hole 16 of the carrier until 3 to 5 teeth on the yoke are visible above the carrier 15. The return spring 11, with drooping ends 18 down, is then centered over and snapped onto the yoke shaft. With the yokes 13, 14 attached to the carrier 15 the sub- assembly is then set into the card guidance hardware (guide rail) which lo...
