Abstract

An umbilical release mechanism (10) for disconnecting an electrical umbilical (14, 16) extending between a host and a releasable vehicle accomplishes the disconnection without imparting any force to the releasable vehicle, and without leaving pieces of the disconnection mechanism (10) in the releasable vehicle. The umbilical release mechanism (10) includes an umbilical connector (12) in which two electrical harness connectors (22, 24) are releasably clamped together, with an intermediate plate (28) using a mat (32) of electrically conductive wires to complete the electrical conduction path between the harness connectors (22, 24). A pair of backing plates (34, 36) having a clamping bore (38) therethrough capture the harness connectors (22, 24) therebetween. A clamping force is releasably applied to the backing plates (34, 36) by engaging a hollow outer shaft (40) through the clamping bore (38), and reacting a clamping force on the backing plates (34, 36) through the outer shaft (40). A ball lock on the vehicle-side end of the outer shaft (40) is released by withdrawing an inner shaft (48) that extends through the hollow outer shaft (40). An interlock on the inner shaft (48) engages and withdraws the outer shaft (40) after the inner shaft (48) has been moved a predetermined distance, effecting the separation.
