  • the threaded coupling element comprises a tooth system, the teeth of which are arranged next to one another in the circumferential direction and point with their tooth height in the axial direction.
  • the socket 11 can for example be attached to the component-fixed coupling element 171 or directly to the base plate 14.
  • the threaded coupling element 172 is basically designed in the form of a ring, the bush 11 being passed axially through the central opening of the threaded coupling element.
  • FIG. 6 shows an assembly view of the torque-controlled coupling 17 with the socket 11.
  • the component-fixed coupling element 171 is connected to the base plate 14.
  • the bushing 1 is in turn arranged within the thread-fixed coupling element 172 with the fastening thread 12 and is firmly connected to the component-fixed coupling element 171 and thus to the base plate 14.

  • a pawl 173 is arranged in a recess of the component-fixed coupling element 171, which is axially pretensioned by a spring 174 against the teeth of the thread-fixed coupling element. At its rear end, the spring 174 is supported against the coupling element which is fixed to the components. A distal end of the pawl 173 is due to the spring preload with the toothing of the threaded coupling element in engagement.
  • the threaded coupling element 172, the spring 174 and the pawl 173 are axially braced between the component coupling 171 and the carrier 13.
  • Each tooth of the toothing on the threaded coupling element 172 has a ramp-shaped first flank 1721, which is designed comparatively flat to the circumferential direction of the threaded coupling element 172 or the thread 12, as well as a steep second flank 1722, which is inclined steeply in relation to the circumferential direction of the threaded coupling element is or includes a larger angle with this circumferential direction than the ramp-shaped flank 1721.
  • the distal end of the pawl 173 has a ramp-shaped first flank 1731, which is arranged comparatively flat to the circumferential direction of the threaded coupling element 172 or the thread 12, as well as a steep second flank 1732, which is inclined steeply with respect to the circumferential direction of the threaded coupling element or includes a larger angle with this circumferential direction than the ramp-shaped flank 1731.
  • the pawl 173 is arranged in such a way that, depending on the direction, a s torque transmitted between the threaded coupling element and the component fixed coupling element or the circumferential force necessary for this, this circumferential force is transmitted between the ramp-shaped flanks 1721 and 1731 or the steep flanks 1722 and 1732 of the toothing on the threaded coupling element and the pawl.
  • the ramp-shaped flanks are oriented in the circumferential direction in such a way that the force transmission between the ramp-shaped flanks 1721 and 1731 takes place when the thread is screwed in or screwed on and tightened towards the end face of the connector.
  • a torque is applied in a direction in which the circumferential force is transmitted between the steep flanks 1722 and 1732, a torque can be transmitted that is essentially limited by the mechanical strength of the teeth of the threaded coupling element and the pawl.
  • the torque that can be applied or supported by the coupling 17 to tighten the thread is limited by the coupling, whereas the torque that can be applied or supported by the coupling to unscrew the thread is greater in any case than the maximum possible tightening torque. In this way it can be ensured that the thread is not overloaded and damaged when it is tightened, while on the other hand it is ensured that a threaded connection once established can be released again.
  • an opening can be provided in the connector housing through which a screwdriver or other suitable object can be inserted in order to block the relative movement of the threaded coupling element relative to the component coupling element.
  • FIGS. 9 to 12 Another exemplary embodiment at which the means for emergency blocking of the coupling are integrated directly in the plug connector is illustrated in FIGS. 9 to 12.
  • FIG. 9 shows a view similar to FIG. 6, with an end-face toothing 175 being arranged on the threaded coupling element 172 in addition to the toothing that interacts with the pawl 173, the teeth of which are arranged towards the front of the connector.
  • FIG. 10 shows a sectional view along the line designated by X-X in FIG. 9.
  • the front toothing 175 also has teeth which are asymmetrical in the circumferential direction of the threaded coupling element.
  • the flatter side of the teeth points in the same direction as in the case of the toothing that interacts with the pawl 173.
  • the carrier 13 has a toothing 135 which is complementary to the front-side toothing 175 of the threaded coupling element 172 and which likewise extends in an annular manner on the same radius as the toothing 175. It can easily be seen that if the toothing 175 engages in the toothing 135, it blocks the coupling in the same direction as the pawl in cooperation with the rear toothing of the threaded coupling element. This is shown in more detail in FIG. 11 as detail XI from FIG.
  • the toothings 175 and 135 on the installation unit come into engagement with one another in such a way that at least in the direction in which the steep tooth flanks interact, the rotation of the threaded coupling element 172 in the installation unit is blocked, such that the Loosening the screw connection between the installation unit and a consumer connection unit, or more generally two connectors, is made possible.
  • the interacting components are shown again in an exploded drawing.

Abstract

L'invention concerne un système de connexion (1) pour établir une connexion électriquement conductrice amovible, comprenant un connecteur femelle (10) et un connecteur mâle (20) compatible avec ledit connecteur femelle. Le connecteur femelle (10) comprend une douille (11) avec des ouvertures de contact concentriques annulaires et des éléments de contact disposés à l'intérieur des ouvertures de contact. Le connecteur mâle comprend une fiche (21) avec des éléments de contact qui peuvent être insérés dans les ouvertures de contact de la douille (11). Des éléments ferromagnétiques sont disposés concentriquement autour de la douille et de la fiche, les éléments ferromagnétiques du connecteur mâle et du connecteur femelle ayant une attraction mutuelle afin de produire une force de retenue entre les deux connecteurs.
