Abstract: An electrical connector is matably attached to an oxygen sensor having a hollow center terminal for exposing the inner electrode of the oxygen sensor to ambient air. The electrical connector comprises a nylon connector body having radially spaced shrouds at a plug-in opening which receives the oxygen sensor terminal. A silicone rubber seal sleeve disposed in the outer shroud sealingly engages the inner shroud and the insulator sleeve of the oxygen sensor to environmentally protect the interface between the oxygen sensor terminal and the mating terminal carried by the connector body. The plug-in opening is vented via grooves in the shrouds. A retaining clip carried by the outer shroud forms a splash shield for the vent inlet. The connector body has an enlarged lead receiving opening which is sealed by a seal sleeve molded on th lead.

Abstract: An electrical connector for a printed circuit board or the like comprises a connector body having two rows of longitudinal terminal receiving cavities respectively disposed on opposite sides of a lateral slot. Each cavity has a forward longitudinal opening and a forward side rib. A terminal having a U-shaped forward end piloted on the side rib is individually retained in each cavity. A resilient cantilevered tongue portion of the terminal extends rearwardly from the U-shaped forward end and is disposed in the lateral slot. The connector body also has two rearward lateral slots. Lock plates are longitudinally slid into each rear slot to a retained position whereat each lock plate prevents withdrawal of all of the terminals in one of the rows.
