Definitions

  • the invention relates to a plug connection for optical fibers with a socket plug, which has at least one socket for receiving a plug pin and a mating connector, such as. B. a pin header for receiving the socket plug, a protective device for protecting the end face of the plug pin being arranged on the plug part, which can be moved from a closed position with a hidden end face of the plug pin into an open position with an exposed end face and the protective device when the plug part is inserted linearly into the mating plug is moved into the open position and when pulling out into the closed position and the movement of the protective device is effected by the interaction of a guide part and a control path between the protective device and the mating connector.
  • the protective device consists of a cover which is pivotably mounted on the plug part, which according to one embodiment variant is simply opened when the plug part is inserted into the mating connector, and according to a second embodiment variant is opened and at the same time is displaced in the direction of the plug part.
  • the design of the protective device as a pivotable cover has the disadvantage that it can easily open when handling the plug part. According to a further development, this is biased by a spring in the closed position, which means that it cannot be prevented, however, that the lid opens unintentionally when handling and contaminants thus reach the end face of the plug pin.
  • the protective device consists of two plates with openings, which are mutually displaced so that the two plates mutually cover their openings when unplugged. Both plates can be moved in the direction of insertion and are biased in their position by springs.
  • the one of the two plates, the openings of which are not aligned with the connector pins, can also be moved transversely to the direction of insertion and is also pretensioned by springs and is pushed over a guide link when the connector part is inserted into the mating connector until the openings of the two plates are aligned with the connector pins. At the same time, the two plates are also pressed in the direction of the connector pins, so that they can enter the mating connector through the openings in the plates.
  • This version of the protective device has the disadvantage that, in the case of multipole plugs, the plug pins cannot be arranged close to one another, since otherwise the openings in the two plates would be too large so that they could cover one another.
  • the invention is therefore based on the object of developing a generic plug connection in such a way that the risk of unintentional opening of the protective device when handling the plug part is minimized and nevertheless safe operation of the protective device is ensured over a large number of plug-in operations.
  • This object is achieved in that the protective device is displaceable perpendicular to the direction of insertion via a linear movement.
  • the protective device By designing the protective device as a slide, the risk of unintentional opening compared to the flap solution is significantly reduced.
  • the simple lateral linear displacement of the protective device can be done in a simple manner by the interaction of a guide part and a control path between the protective device and mating connector and without the use of any springs which limit the service life. Since the protective device is laterally displaced relative to the connector pins, these can also be arranged as closely as desired.
  • the protective device when the plug part is inserted into the mating connector, can first be displaced linearly perpendicular to the plug direction and then counter to the plug direction in the direction of the plug part.
  • the design is particularly advantageous if the plug pin is designed to lead in the plugging direction with respect to the plug part and a socket is formed in the mating plug, which projects inwards in the receiving direction.
  • the protective device is displaced by the two linear movements so that it does not hinder insertion of the connector pins into the receptacle sockets in the mating connector.
