Terminal connector

摘要

A terminal connector includes a knob at its outer end. A knob cover snaps into the knob to enable rotation of the knob. The knob cover has resiliently urged lock tabs which snap over lock steps on the knob and into grooves beyond the lock steps. The sides of the lock tabs engage sides of the grooves to transmit torque to the knob. The knob covers are color coded so that a selected color can be installed on a selected knob to indicate its function. An insertion prevention lid is integrally molded over a plug insertion opening of the knob cover to prevent insertion of a connector plug therein. A frangible perimeter of the insertion prevention lid permits its removal to enable insertion of a connector plug.
