Particularly in the area of data transmission, cables and connectors that have a high level of electromagnetic compatibility (EMC) are required.
  • EMC electromagnetic compatibility
  • cables and some of the cores they contain are sheathed with conductive wire, wire mesh and / or foil.
  • various means of shielding connection are used.
  • resilient elements made of electrically conductive materials are preferably used in order to transmit an electromagnetic shield from an electrically conductive cable via a connector to a mating connector.
  • spring washers are usually recommended, particularly with circular connectors.
  • corrugated spring washers for shield connection is particularly popular with circular connectors.
  • the object of the invention is to equip known circular connectors with push-pull locking to an element for shield connection, which can be produced easily and cost-effectively and can be used reliably.
  • the embodiment according to the invention proposes a round plug connector for releasably connecting lines, having at least one housing element for receiving at least one insulating body and at least one locking element for releasably connecting to a mating connector.
  • the housing element accommodates at least one circumferential spring element.
  • the spring element is made of an electrically conductive material for connecting an electromagnetic shield and is characterized in that the spring element has at least one ring held in at least one recess in the housing element and at least one essentially axially extending wing.
  • lines preferably refers to the electrically conductive cores of a cable.
  • an optical signal line or a combination of electrically conductive wire and / or optical signal line and / or a fluid line can be used.
  • the “housing element” means in particular at least one electrically conductive component of the circular connector, which is located in the connection area with a mating connector.
  • the housing element is very particularly preferably designed as a metallic sleeve.
  • a round plug connector can have various housing elements, for example a union nut for connecting the round plug connector to a strain relief and / or a cable outlet.
  • Plastic cylinders which have at least one through opening for receiving at least one contact element, are usually used as the insulating body.
  • the contact element establishes the connection between the electrical and / or optical and / or fluid transmission with a corresponding contact element.
  • the corresponding contact element is usually located in a mating connector corresponding to the circular connector or in a corresponding add-on housing.
  • a locking element is a component which interacts with the mating connector in such a way that undesired loosening of the connector is prevented.
  • the spring element according to the invention for shield connection comes into its own particularly advantageously when a so-called push-pull locking mechanism is used.
  • Such locking mechanisms are designed with latching shapes so that the respective latching shapes interact with one another when the plug connectors are plugged together.
  • release forms for example catch hooks
  • this connection can be easily released by applying a tensile force on the housing element provided for this purpose.

  • the recess is also particularly advantageously designed with at least one, essentially axially arranged pocket, which is designed to at least partially accommodate the wing of the spring element.
  • a preferred embodiment suggests that the wing of the spring element is aligned against the plug-in direction of the circular connector, so that the ring points in the direction of the mating connector. This means that when the circular connector is plugged into a mating connector, the mating connector is in any case first passed over the ring of the spring element before the wing of the spring element is reached and contacted.
  • This embodiment simplifies the plugging process of the circular connector with a mating connector and enables reliable contacting of the mating connector with the spring element.
  • a clever embodiment provides that the wing has at least one concave curvature which runs essentially outside an imaginary cylinder, the base area of which is formed by the inner diameter of the ring.
  • the wing arranged on the ring is shaped in such a way that it moves away from the housing element and the ring of the spring element. After reaching a maximum deflection, the wing continues to run away from the ring, but at least partially again towards the housing element.
  • This embodiment not only simplifies the plugging process of the circular connector with a mating connector, but also the release process of the plug connection, since locking elements are easily guided over the spring element.
  • the wing has at least one concave curvature, the highest deflection of which runs essentially outside an imaginary cylinder, the base area of which is formed by the outer diameter of the ring.
  • This embodiment ensures reliable contact between the mating connector and the spring element. In this way, the shield connection is ensured in a simple and effective way.
  • the wing of the spring element is shaped in such a way that the round plug connector is in contact with the spring element at two points on the housing element. The first contact point between the housing element and the spring element is the ring of the spring element. The second contact point is obtained when the circular connector is plugged in with a mating connector. The maximum deflection of the wing ensures that the wing comes into contact with the mating connector. This contact point in turn pushes the wing in the direction of the housing element of the circular connector, so that the end of the Wing comes into contact with the housing element, whereby the second contact point is at least produced, preferably reinforced.
  • the spring element has a number of wings which is identical to the number of locking elements, the number being greater than or equal to two.
  • the spring element is preferably designed with three, four or five wings.
  • an embodiment with at least six wings is provided. This embodiment enables both a secure locking of the circular connector with a mating connector and a stable shield connection.
  • a particularly clever embodiment recommends alternating the wings of the spring element and the same number of locking elements around the circumference of the housing element.
  • Both the shield connection and the locking of the circular connector with a mating connector are advantageously reinforced in this way.
  • This embodiment is particularly advantageous when using a push-pull locking mechanism. In this way, the locking elements and / or the locking forms of the mating connector safely come into contact both with the locking elements of the circular connector and with its spring element.
  • this embodiment provides that a radially circumferential locking hook of the mating connector can be brought into locking engagement with the locking elements of the circular connector, the spring element between the locking elements resting against these locking hooks of the mating connector and thus ensuring the connection of the screen.
  • the spring element is in electrically conductive connection with the housing element at least through the ring and is in electrically conductive connection with the mating connector at least when the wing is deflected.
  • This embodiment enables installation with a reduced installation space, in which the wing is made just so long that a curvature can be formed. In this case, however, the end of the wing is not pressed against the housing element of the connector even when it is plugged in. The end of the wing is therefore designed to float freely. In particular, this design enables the circular connector to be plugged more easily with a mating connector.
  • the spring element is in electrically conductive connection at least through the ring and at least one end region of the wing with the housing element and is in electrically conductive connection with the mating connector at least with a deflection of the wing.
  • This embodiment is basically a little longer than the previously mentioned embodiment, but offers the advantage of more secure contacting of circular connectors or the
  • the spring element has at least one ring, the wing of which is arranged on the ring, deformed by at least 60 ° against the insertion direction.
  • This embodiment enables the spring element to be seated more firmly on the housing element of the circular connector, which means that an embodiment with a free-floating wing can also be used more easily and securely.
  • a spring element is proposed here, the wings of which are reshaped essentially by 90 ° on the ring. Bending processes in particular are meant as forming, in particular roll bending, die bending or free bending and / or rounding, but possibly also rolling. The use of further forming processes is conceivable and usually known to the person skilled in the art. This results in a ring of the spring element aligned concentrically to the longitudinal axis with at least one at least essentially axially extending wing.
  • a refined embodiment also provides that the spring element is arranged in a recess in the housing element, the ring being inserted in a further recess in the housing element.
  • the spring element is essentially received in a recess in the housing element, the ring being arranged in a further recess, in particular a circumferential groove.
  • a particularly advantageous contact between the spring element and the housing element of the circular connector can be established through this recess in the recess.
