  • Patent number: 6322239
    Abstract: A vehicle lamp is provided with a feeder device for simplifying the labor of disposing feeder cords while improving accuracy. The vehicle lamp has a movable reflector tiltably supported by a lamp body via an aiming mechanism. A back cover is detachably fitted in an opening formed in the rear of the lamp body. The back cover includes a terminal for conducting the terminal of a feeder cord connected to a light source provided in the lamp body, and the terminal of a power supply cord connected to a power supply for supplying power to the light source.

  • Patent number: 6315611
    Abstract: A retaining projection 37 for engagement in a retaining groove 14, formed in a base portion 12 of a bulb 10, is formed on one of a pair of holder pieces 34 of a metal terminal 30, and a connecting projection 36 is formed on the other holder piece 34, and this connecting projection 36 is to be opposed to that portion of a lead wire 13 lying between its proximal end portion and its intermediate portion, and is projected toward the lead wire 13 so as to be held against the lead wire 13. With this construction, even if the base portion 12 is held between the holder pieces 34 and 34, with the distal end portion of the lead wire 13 displaced to be tilted, the connecting projection 36 never fails to be held against the proximal end portion of the lead wire 13, thereby positively achieving an electrical connection therebetween.

  • Patent number: 6254436
    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.

  • Patent number: 5664870
    Abstract: A vehicular lamp having a structure of electrical connection between a lamp bulb serving as a light source installed in a lamp body and an external power source for supplying electric power to the lamp bulb which includes a back cover detachably attached to a bulb insertion hole formed in a back surface of the lamp body and a relay connector connecting with both the lamp bulb and an external power source, and the relay connector is constituted by an internal electrical connection section disposed at an inside of the back cover for electrically connecting with the lamp bulb and an external electrical connection section disposed at an outside of the back cover for connecting with a harness for the external power source. The internal electrical connection section and the external electrical connection section are formed integrally with each other by a conductive terminal which penetrates the back cover.
