Patent No. EP4122056 (titled "Shielded Plug Connector Module") was filed by Harting Electric Stiftung on Mar 10, 2021. The application was issued on Feb 19, 2025.
A plug-in connector module comprises a cuboidal insulating body with parallel plug-in and cable connection sides linked by continuous contact chambers for conductive plug-in contacts. Two opposite narrow sides feature integrally moulded detent lugs of differing shapes or sizes to ensure correct orientation (polarization) within a modular frame. The module is form-fittingly surrounded by a peripheral shield element covering over 50% of both the broad and narrow sides, with openings at the plug-in and cable connection sides. Additionally, at least one separate shield transfer element is positioned on at least one broad side in electrical contact with the peripheral shield element to enhance shielding against high-frequency electrical and magnetic interference.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
