An electrical connector adapter (40) is disclosed for electrically interconnecting a portable electronic component such as an MP3 player, CD player, or other portable device with sound or other equipment in a vehicle. The adapter (40) includes a one-piece insulating housing (60) having a system mating end (42) for interconnecting to a vehicle's electrical system and a component mating end (44) for interconnecting to a portable electrical component. Three electric contacts (62, 64, 68) are retained in three openings (90, 92, 94) respectively in the housing (60) and are arranged to electrically mate with a plug (54) of a portable electrical component.

A lever-type electrical connector assembly reduces the connection mating forces required to mate female and male connectors. The connector assembly employs a first connector with cam follower projections, a base housing with cam grooves ans a sliding guide rail, a slide lever housing including a sliding projection and a sliding guide rail, and a cover housing pivotally mounted on the base housing, the cover housing having a sliding projection. As the cover housing is rotated from an open to a closed position, it engages the sliding projection in the guide rail to permit rotation of the lever housing. This rotation engages the sliding projection in the guide rail. As the lever housing is rotated from an open to a closed position, it rotates the cam grooves to engage the cam follower projections thereby drawing the first connector into the base housing to a connected position.
