Abstract
A plug connector has a conducting metal housing and a plurality of signal lines in the form of connection pins disposed in rows and columns. A planar filter assembly includes a planar filter having a ground electrode and two opposed edges constructed as conductive side regions being connected to the ground electrode and being connected to ground through the housing. A substrate has openings formed therein each receiving a respective one of the connection pins. Capacitors are each disposed in the vicinity of a respective one of the openings for a respective one of the connection pins. Each of the capacitors has a first coating being connected to a respective one of the connection pins and being extended into a respective one of the openings, a second coating connected through the housing to ground, and a layer-like dielectric disposed between the first and second coatings. Contact inserts are each soldered in a respective one of the openings for retaining a respective one of the connection pins and each have at least two contact prongs electrically connecting a respective one of the connection pins to the first coating of a respective one of the capacitors.
