Patent ID: 8137117

Claim:
An electrical supply device for a discharge lamp of a motor vehicle headlight that comprises: an electronic module for converting source electric current into supply electric current for the discharge lamp; a housing that encloses said electronic module that comprises an electrically conductive material so as to form electromagnetic shielding; an electrical connection harness that is intended to electrically connect said electronic module with the discharge lamp; a shielding envelope comprising an electrically conductive material that surrounds said electrical connection harness so as to form electromagnetic shielding; said housing and said shielding envelope being electrically connected to a common reference electrical potential (−); wherein said housing and said shielding envelope are connected in parallel to said common reference electrical potential (−); wherein said housing further comprises: first connection means in which a first reciprocal connector electrically connected to said common reference electrical potential (−) is intended to be engaged mechanically in a first connected position; second connection means in which a second reciprocal connector of said electrical connection harness is intended to be engaged mechanically in a second connected position, said second reciprocal connector being surrounded by said shielding envelope of said electrical connection harness; said first connection means being arranged adjacent to said second connection means; and a contact element is arranged so as to electrically connect said common reference electrical potential (−) to said shielding envelope when said first and second reciprocal connectors simultaneously are in their said first and second connected positions, respectively.
