Connector back shells having a plurality of cable exit angles
View Patent ↗A wiring connector back shell having a plurality of cable exit angles is disclosed. The back shell has a single transition element with a number of holes fashioned therein, which allow a cable retaining device to be fastened thereto. The cable retaining device provides strain relief for the cable exiting the back shell, as well as determining the exit angle of the cable. The cable retaining device has integral pins which mate with hole patterns in the transition element, and are locked in place with a retaining collar. Alternatively, cable ties or tie wraps may be utilized to fasten the cable to the transition element. The system provides a high reliability, low mass method for cable back shells wherein cable exit angles are easily changed or chosen in the field.
