Negative power coupler

A negative power coupler, also known as a negative flow coupler, was an engine component used in small starships. If the prong end of a positive flow detonator was fitted into the coupler's Garris socket, the positive flow overheated the metals of the two components, fusing them together. The subsequent build up of power caused a critical reaction leading to an explosion.
