Abstract

The utility model discloses a wire harness for an automobile headlight, which comprises a main plug, wherein a plurality of connecting holes and a plurality of conductive sleeves are arranged on the main plug, each conductive sleeve comprises a vertical connecting part and a plurality of elastic sheets, the elastic sheets are arranged outside the vertical connecting parts in a spacing ring mode and are connected with the vertical connecting parts, one sides, close to orifices of the connecting holes, of the elastic sheets incline outwards, the conductive sleeves are inserted into the connecting holes, and the elastic sheets deform under the action of the outer walls of the connecting holes and are abutted against the outer walls of a wire harness core. When the conductive sleeve and the wire harness are synchronously inserted into the connecting hole, the elastic sheets deform towards the inner side of the connecting hole under the action of the wall of the connecting hole and are pressed on the wire harness core, so that the wire harness is locked by utilizing the elastic sheets, the mechanical locking capacity of the conductive sleeve on the wire harness is optimized, the connection reliability is improved, the elastic sheets are enclosed to form side walls matched with the wall of the connecting hole under the action of the connecting hole, the contact area between the elastic sheets and the wire harness core is increased, and the electrical performance is improved.
