  • Anti-reversal end cap for universal passenger control unit
    Patent number: 6735309
    Abstract: An anti-reversal end cap with tab to prevent improper stowage of a handset into its cradle. The end cap is formed by joining two members together to route a cable from an in-flight entertainment system to the handset. The end cap has a protruding tab which interferes with the cradle if the handset is improperly stowed. The end cap can be taken apart to free the cable from the handset such that the cable does not need to be re-terminated. The tab on the end cap has a generally wedged shape to prevent binding with the cradle and to ensure smooth ejection.
