Abstract: A method for producing a modular electrical connector assembly for a vehicle control unit, the connector assembly having a module carrier and at least two connector modules disposed side-by-side on the carrier. Each connector module has a connector housing collar and a plurality of contact elements disposed in a contact area within the connector housing collar. First, one of the connector modules is placed in an opening in the module carrier and positioned precisely relative to the module carrier. The connector module is pressed with a hold-down device against the module carrier retained in a holding device. In this state, the connector module is laser-welded to the carrier in an attachment region with a laser beam. Laser welding permits a reliably stable and fluid-tight, material-locking connection between the components, and an advantageous, space-saving placement of the attachment region laterally within the collar, with higher manufacturing precision and small manufacturing tolerances.

Abstract: A method for producing a modular electrical connector assembly for a control unit in a motor vehicle is provided. The connector assembly has a module carrier, as well as at least two connector modules which are disposed side-by-side on the module carrier. Each of the connector modules has a connector housing collar, as well as a plurality of contact elements which are disposed in a contact area within the connector housing collar. To produce the connector assembly, first of all, one of the connector modules is placed in an opening in the module carrier and is positioned precisely relative to the module carrier. The connector module is then pressed with the aid of a hold-down device, for example, against the module carrier retained in a holding device, for instance. In this state, the connector module is laser-welded to the module carrier in an attachment region with the aid of a laser beam.

Abstract: A modular electrical plug connector assembly for control units in a motor vehicle includes a module rack and at least first and second plug-in modules that are situated in the module rack and that each includes respective housings shaped to accommodate respective electrical plug connectors. The housings are provided with respective electrically conductive contact elements. The first and second plug-in modules are positioned relative to one each other in a predetermined manner in the module rack, and are inseparably connected to the module rack by a joining process.
