Abstract: Disclosed is an anti-decoupling mechanism for maintaining the assembly of sets of tubular components using rotating coupling nuts such as circular electrical connectors. To accomplish this, a multiplicity of detent slots (teeth) engage a multiplicity of flexible detent tooth engaging members—from one such member in the mechanism up to one for each tooth in the mechanism. The geometry, multiplicity, and spacing of the detent components allows on the order of 47 or more locked positions on a tooth ring 0.6 inches in average diameter at the teeth. Adding a second set of teeth utilizing a second direction of flex of the flexible detent tooth engaging members (circumferential) can double this amount. By compound sloping of the detent teeth the mechanism takes advantage of the natural axial motion of the coupling nut to increase but limit the force on the flexible detent tooth engaging members as the components are progressively mated and thereby beneficially altering the torque required to rotate the coupling nut.
