Abstract

An injection molding nozzle with an electrical heating element having a terminal for connecting external leads with an insulative connector formed of ceramic material. The insulative connector has a pair of spaced parallel longitudinal bores in which the outer end portions of the heating element conductive wires and the bared inner end portions of the external leads overlap and are secured together by set screws. A steel cap fits over the ceramic connector to protect it and provide the combination with sufficient structural strength to prevent damage during use. A resilient seal mounted between the ceramic connector and the cap also prevents damage to the connector and prevents moisture entering into the connector.
