Abstract: A spring bushing for miniature plug-in connectors, has at least one housing chamber in a bushing housing, for accommodating a one-piece contact spring, the contact-giving spring tongues of which are bent out of a flat sheet-metal punched part, at least on one side, without coverage, whereby the one end of the sheet-metal punched part, a crosspiece that carries the spring tongues, forms a fixed connector, and the other free end forms the accommodation region for a contact blade. The insertion depth of the contact spring for a contact blade is equal to or less than its insertion width.

Abstract: A method for repair soldering of multi-pole miniature plug connectors on printed circuit boards, having signal contact pins in the SMT design and shroud pins in the THR design. The plug connectors have shrouds whose shroud pins project out on the back of the printed circuit board. Preforms are glued onto the SMD signal contact pins, and the repair plug connectors are set into THR holes of the board with their shroud pins. The signal contact pins are soldered using SMT technology. Subsequently, the shroud pins are soldered from the back of the board. The solder connects with the solder eyes of the solder holes on the back of the board, as well as flows into the ring gap between the metallized inside walls of the solder holes and the shroud pins in the circuit board, and produces a material-lock connection. Finally, the shroud pins that project out are shortened.

Abstract: A multi-pole, multi-row plug-and-socket connector with shielding, for placement on printed circuit boards, circuit cards, and similar electrical components, which can be used in an electrical or electronic system includes electrical contact parts for the transmission of signals, which possess a connection section on one end and an electrically conductive attachment section on the other end, as well as an electrical shielding, which possesses at least one electrically conductive contact section. The free ends of the electrically conductive attachment sections of the electrical contact parts are SMD contacts. The at least one electrically conductive contact section of the shielding is, at the same time, an attachment pin which projects into a passage hole of the printed circuit board when the plug-and-socket connector is disposed on the same, for the purpose of connective soldering using THR technology.

Abstract: A one-piece, multi-shank contact spring for miniature plug connectors, particularly for high-frequency signals, having a region that contacts a plug-in lead. The contacting region (A) extends all the way to the free end of a plugged-in plug-in lead.
