Abstract

An electrical connector for an automotive headlamp includes a connector housing formed from an insulating material and electrical terminals which are electrically conductive and inserted into the respective sleeves of the connector housing. Respective planar connecting portions of the electrical terminals are disposed in the same plane and are disposed to as to about a plane in which corresponding external terminals provided in the lamp are disposed. Thus, the length of the connector housing in the direction perpendicular to the plane of the planar connecting portions can be reduced, thereby reducing the width of the electrical connector. As a result, the overall height of the headlamp can be reduced.
