Abstract
A welding arrangement for plastic components includes a base member, a primary member abutting onto the base member and provided with a first positioning feature that engages a corresponding first positioning feature provided on the base member. A secondary member is vibration welded to the base member so as to at least partly interpose the primary member between the secondary member and base member. Because the welding is performed while the primary member is properly positioned relative to the base member on account of the first positioning feature cooperating with the corresponding first positioning feature, the positional precision of the primary member is ensured. The primary member may be additionally provided with a second positioning feature that engages a corresponding second positioning feature provided on the secondary member, so as to permit positional adjustment between them in a prescribed direction corresponding to a direction of movement of the vibration welding.
