  • Patent number: 5462443
    Abstract: Plug-type connector for producing a contact connection between a flat module (i.e., a printed circuit board) and a component part (i.e., a loudspeaker) having electrical terminals. The plug-type connector can be quickly connected to the flat module in a problem-free manner. The plug-type connector can be attached in the desired direction of assembly so that robotics can be used in the fabrication. The plug-type connector is designed as an essentially U-shaped part that can be plugged onto the edge region of the flat module. The legs of the plug-type connector have hook-shaped, projecting securing portions directed toward one another that electrically contact with contact pads or tracks applied on the flat module.
