Abstract

A contacting unit has a housing consisting of a base plate and a cover plate with a plastic frame. A printed circuit board, having a strip plug for contacting a computer slot and a contact field for contacting a chip card, is mounted between cover plate and base plate that such between the printed circuit board and the base plate an insertion channel is defined and such that the strip plug is located at a first narrow side of the housing. The printed circuit board is secured by the plastic frame. The insertion channel has an insertion guide located at the opposite narrow housing side. The base plate and the cover plate are separate stamped sheet metal parts, and at least the longitudinal edges have inwardly bent tabs. The base plate has plastic holders for securing opposite ends of the strip plug. The insertion guide is a profiled plastic member having a length matching the length of the narrow side. It is connected to the base plate and has an insertion slot allowing passage of a chip card into the insertion channel. The profiled plastic member has a platform projecting into the housing and providing a support surface for the printed circuit board. The plastic holders and the profiled plastic member are injection molded onto the tabs of the base plate. The plastic frame is injection-molded to the tabs of the cover plate. The cover plate and the base plate are fastened to one another by an adhesive, ultrasound welding or hot-pressing.
