Definitions

  • the invention relates to a half-shell clamping sleeve, a round plug connector and a plug-in system with a round plug connector and a complementary plug-in element.
  • the invention is in the field of connector technology, in particular in the field of circular connectors for a push-pull connector system.
  • the circular connector often has a shielding element for that part of the circular connector in which, due to the contacting of cable cores of a cable with a connection element of the circular connector, no braided shield of the cable is arranged over the cable cores.
  • complete electrical shielding of all cable areas, the cable contact areas and the plug-in areas are an important prerequisite for enabling trouble-free operation.
  • the round plug connector for the area to be shielded often has a hollow cylindrical shield element which is firmly connected to a connection element of the round plug connector and which is arranged around the cable area to be shielded.
  • Reliable contact between the shielding braid of the cable and the shielding element of the circular connector is often a problem, since the shielding element is usually a rigid metal cylinder and contact with the shielding braid of the cable can be unintentionally released by moving the cable in the area of the circular connector.
  • One possibility for more reliable shielding is a configuration in which two metallic half-shells are used for electrical shielding are each aligned on the connection element of the circular connector and arranged around the cable and, in addition, a metallic clamping sleeve is aligned on the side of the metallic half-shells that is opposite the connection element.
  • the braided shield of the cable is clamped in by the metallic half-shells and the clamping sleeve.
  • the two aligned half-shells and the clamping sleeve are fixed in their arrangement.
  • the clamping sleeve closes when it is screwed around an insulation of the cable and forms a fixed connection between the circular connector and the cable.
  • a first aspect for achieving the object relates to a half-shell clamping sleeve for electrically shielding a cable in a circular connector, having a hollow, metallic half-cylinder; wherein a groove is formed in the longitudinal axis direction of the half cylinder on a first end face of the half cylinder; a second, opposite end face of the half-cylinder being designed as a clamping sleeve; and wherein the half-shell clamping sleeve is designed in such a way that, in a mounted state in a circular connector, the first end face of the half-cylinder can be positively aligned on a connection element of the circular connector, a cable connected to the connection element can be mechanically fixed by means of the clamping sleeve and the clamping sleeve with a braided shield of the Cable is electrically connectable.
  • an assembled state is understood to mean a state in which a round plug connector, which has at least one half-shell clamping sleeve according to the invention, is electrically connected to a cable.
  • at least one half-shell clamping sleeve is arranged in the circular connector, which is aligned with a positive fit on a connection element of the circular connector.
  • the clamping sleeve of the half-shell clamping sleeve fixes the cable mechanically and is electrically connected to the braided shield of the cable.
  • the half-shell clamping sleeve according to the invention provided for the electrical shielding of a cable replaces one of the half-shells and one half of the clamping sleeve, which are arranged in a conventional round plug connector for shielding a cable, as described above.
  • Two half-shell clamping sleeves thus replace the conventional two half-shells and the clamping sleeve, which are necessary for the configuration of a shielded circular connector.
  • Electrical shielding is understood to mean a closed sheath made of an electrical conductor, for example a wire mesh and / or a metal cylinder, around an object, which is also referred to as a Faraday cage.
  • This electrical shielding creates a field-free area within the closed envelope even in the case of external static electrical fields as a result of influence.
  • a closed sheath made of an electrical conductor also shields high-frequency alternating fields because eddy currents are induced on the surface of the shield, which counteract the external field according to Lenz's rule. In this case, however, the shielding effect is not ideal, but is characterized by finite shielding attenuation and penetration depths into the shield.
  • Shields made of non-ferromagnetic metal because of their finite conductivity, shield high-frequency alternating fields when the metal layer is significantly stronger and / or thicker than the penetration depth of the induced currents.
  • the shielding effect is not tied to a specific shape. Static or slowly varying magnetic fields, such as the earth's magnetic field, are protected by an electrical shield not shielded.
  • the cable is to be understood as a single-core or multi-core composite of cable cores and / or individual lines sheathed with insulating materials, which is used for the transmission of energy and / or information.
  • Different plastics are usually used as insulating materials, which surround the wires used as conductors and insulate them from one another.
  • Electrical conductors usually consist of copper, more rarely aluminum or suitable metal alloys.
  • the cable follows a mostly cylindrical or similar geometry and can contain additional layers of insulating material or metallic foils and / or braided shields in the overall structure for the purpose of electromagnetic shielding and / or mechanical protection.
  • the circular connector can be designed as a male or a female connector.
  • the plug connector can be designed as a plug socket or a plug socket.
  • the round plug connector can be connected in a plug-in area with a complementary plug-in element and / or a complementary plug connector, in particular a female or male round plug connector.

  • the wall thickness is preferably designed to enable shielding from high-frequency electromagnetic waves.
  • High frequency is understood to mean a frequency range from 3 MHz to 30 THz, and in particular the shortwave range from 3 MHz to 30 MHz, the VHF (Ultra Short Wave) and / or VHF (Very High Frequency) range from 30 MHz to 300 MHz, the UHF (Ultra High Frequency) range from 300 MHz to 3 GHz, the SHF (Super High Frequency) range from 3 GHz to 30 Ghz, the EHF (Extremely High Frequency) for 300 GHz to 3 THz and the THF (Tremendously High Frequency) range for 3 THz to 30 THz.
