Abstract: The connector assembly may include a ratcheting feature which prevents the coupling nut from turning due to vibration or shock. The coupling nut may include an engagement surface. The engagement surface may be a series of peaks and valleys. The connector may include a spring washer. The spring washer may be located between the coupling nut and the connector body. The spring washer may include a protrusion. The protrusion engages the engagement surface. In a second embodiment, the coupling nut may include a spring pin. The connector body may include an engagement surface. The engagement surface may be a series of peaks and valleys. The spring pin engages the engagement surface. The spring pin may be made of multiple components, for example, a pin and a spring. In another embodiment, the spring pin may be a single component.
