  • Plug connections with plugs, plug-in parts and / or connecting blocks according to the invention are required wherever no continuous conductors can be provided, so for example for couplings between railway wagons, etc.

  • the conductive partial area of the pin comes into contact with a conductive area of the sleeve.
  • the main contact area is only arranged on the side of the pin. If a contact is provided at the inner end of the sleeve for the pin to come into contact with the end face, the sleeve and the pin length must match exactly. This necessary match can only be achieved with a large amount of processing.
  • the known plugs with end contacts tend to break contacts when vibrating parts are connected.
  • the outer diameter of the pin and the inside of the sleeve must fit together so that the pin can be inserted and removed without great force and the lateral contact area lies sufficiently close to the sleeve. Again, this can only be achieved with a large amount of processing. Since the above pins are dirty on the side and on the end of the connector when not inserted, there is a risk that the Contact becomes bad, or the plug can no longer be inserted into the plug-in part.
  • the electrical lines are often used for the electrical supply of devices, such as measuring, control and drive units. From and to these devices, information must also arrive in parallel with the power supply. For example, in modern train compositions, wheel speeds and drive power are measured on individually driven wheels and curve radii and the corresponding optimal drive power are calculated in a central computer in order to control the drive power.

  • the connector should also protect the ends of the optical fibers in a corresponding manner, so that parallel electrical and optical fiber connections can be connected in a uniform manner without any problems.
  • a corresponding plug-in part belongs to the plug.

Abstract

L'invention concerne un connecteur (31), une partie enfichable (32) assortie et un bloc-raccord (30) pour connecteurs à fiches situés entre des lignes électriques (12a1) et des guides d'ondes lumineuses (12a3). Jusqu'à présent, les connecteurs présentaient l'inconvénient de permettre aux monteurs chargés de les installer, d'avoir relativement facilement accès, même par inadvertance, à la surface de contact de la broche de connexion (1e). Selon l'invention, il est prévu un ressort de rappel (6) qui ramène la broche (1e) dans une position protégée lorsque le connecteur est en position de repos.
