Improved sealed vehicle lamp and assembly method therefor
摘要
A vehicle lamp assembly (27) has an opaque housing portion (10) and a light transmissive lens portion (35). The housing (10) includes a peripheral channel (21) for accepting a sealing adhesive (33) and a complementary peripheral tongue (29) on the lens portion (35). The bottom of the channel is characterized by a plurality of energy directors (25) which contact the tongue (29) and are locally upset by an ultrasonic weld apparatus to provide local welding between the lens and housing. The local welding provides fixtureless retention of the respective parts during the curing of the sealing adhesive. <IMAGE> <IMAGE>
