ABSTRACT:
The invention provides a terminal lug-water sealing plug coupling structure in a water-proof electric connector used for automotive wiring harnesses.
With the wire already passed through the water sealing plug, the wire conductor is crimped by the wire conductor crimping portion and the wire insulation is crimped by the wire insulation crimping portion to securely connect the wire to the terminal lug. At this time a pair of engagement projections are formed at the top and bottom of the wire insulation crimping portion.
In this condition, the water sealing plug is moved over the wire until the engagement projections fit into the engagement holes, firmly holding the terminal lug and the water sealing plug together. This engagement between the projections and the holes permits secure connection of the water sealing plug to the terminal lug in a predetermined attitude.
