Abstract

A vehicle headlight is arranged to prevent moisture from entering into a lighting circuit and a lighting space. A back cover has a cover main body 19 fitted into a fitting portion 5 of a lamp body 2 and made of resin material and connection terminals 20 embedded in the cover main body (except a part of the terminals) and made of metal material and in which the cover main body and the connection terminals are molded integrally. Component inlaying portions in which electronic components that constitute a lighting circuit of a discharge lamp and are connected electrically to the connection terminals are inlaid respectively are provided to the cover main body. A part of the connection terminals protruding from the cover main body is formed as connector terminal portions of a power supply connector for supplying power to the discharge lamp.

Description

technical field [0001] The present invention relates to a vehicle headlamp. Specifically, it relates to the technical field of integrally molding the cover body and the connection terminal of the connector terminal part having the power connector to prevent moisture from entering into the lighting circuit and the space of the lamp.
