ABSTRACT:
A two-part screw-type coupling suitable for coupling together electrical and/or mechanical components in an aircraft, for example, has a rotation lock feature that prevents the unintentional spontaneous loosening of the screwed connection as a result of vibration and shock. The coupling includes a generally cylindrical support body and a collar nut rotatably mounted thereon and retained by a retaining element. A rotation lock element locks the collar nut and the support body together against relative rotation. The lock element includes a spring or a spring-loaded ring, which is rigidly connected to the collar nut or the support body and which applies a sufficient clamping tension against the other part of the coupling to achieve the desired locking function. The rotation lock can provide a finely stepped static adjustment and locking, or a fine step-less dynamic adjustment and locking of the tightening torque of the collar nut on a component to which the coupling is screw-connected. For the stepped adjustment, a spring or a knurled ring engages a knurled surface having radial or axial knurled ridges on at least one of the two parts of the coupling. For the step-less adjustment, a spring applies a biasing torque between the two parts of the coupling.
