Definitions

  • the invention relates to a connector with a connector and a mating connector, which can be plugged together to form the connector, according to claim 1 and an embodiment of such a connector according to the features of the preamble of claim 2.
  • plug-in connections which have a plug connector and a mating plug connector corresponding thereto, wherein these two plug connectors can be plugged together to form the plug connection.
  • the mating connector when it has been attached to the connector can be pulled by pivoting the lever into the housing of the connector, after the successful and finished pivoting operation of the lever, the mating connector is locked first locked in the housing of the connector and the mutually corresponding contact partners of connector and mating connector are electrically contacted with each other. Thereafter, the locking device is actuated in order to realize the further locking (secondary locking), so that it is no longer possible that the lever can move out of its assumed position after pivoting out, so that thereby the first locking during operation of the connector remains secured ,
  • the invention has for its object to provide a connector or a connector with a housing on which a pivotable lever is arranged, with the or the initially described
  • the invention describes a self-locking locking device according to claim 1, which is released by the end position of a retraction gate (e.g., lever) and locks the lever.
  • a retraction gate e.g., lever
  • Locking device is previously on a spring element, in particular a Leaf spring, tensioned and tension-free in end position (only a minimum residual tension on the leaf spring is possible).
  • a connector has a connector (shown in the figures) and a mating connector (not shown). These are put together and locked first. Thereafter, a secondary lock with the described locking device is required. This secondary locking can only take place after the initial locking and when the two connectors have been properly mated. After actuation of the locking device, an automatic end locking of the connector takes place. This end lock is only possible if previously the end position of the first lock and thus the system lock was performed, but the final hedge of the lock is done automatically and no additional handle or operation required.
  • the invention provides that further on the housing cooperating with the lever biased and displaceable locking device is arranged.
  • the pivoting of the lever causes entrainment of the mating connector for the purpose of introduction into the connector during the mating process.
  • the lever has been completely or almost completely pivoted, it causes the first locking of the mating connector in the connector and at the same time the mating operation is facilitated due to the lever forces acting.
  • a prestressing leaf spring is arranged between the housing and the locking device.
  • the locking device has at least one lever element and the lever at least one receiving space, wherein after the displacement of the locking device whose respective lever element is partially immersed in the associated receiving space.
  • the at least one lever element preferably exactly two mutually parallel lever elements, the locking device is initially in a position from which it can not be moved out. This causes in an advantageous manner that the at least one lever element does not block the pivoting operation of the lever. Only after the lever has been pivoted, a movement of the at least one lever element is released by the lever, so that by moving the locking device, the at least one lever element can dive into its associated receiving space of the lever. Once this is done, further pivoting of the lever, no matter in which direction, is blocked.
  • the at least one lever element has thus assumed its end position, it can be thought of setting it in its end position, in particular by a latching operation.
  • the outer geometry, in particular length and cross-section of that part of the at least one lever element, which dips into the associated receiving space of the lever corresponds in one embodiment almost the same internal geometry of the receiving space of the lever. It may be thought in an alternative embodiment that between the outer geometry of the free end of the lever member and the inner geometry of the receiving space of the lever, a certain amount of free space is available so that minimal movements of immersed in the receiving space of the lever part of the lever element are allowed can.
  • a rocker element cooperating with the at least one lever element of the locking device and the lever to be arranged on the housing.
  • rocker With this arranged on the housing rocker a first stop for the free end of the at least one lever element is realized on the one hand.
  • the rocking element cooperates in its first position with the free end of the at least one lever element and blocks a displacement of the locking device in the direction of the receiving space of the lever. This ensures that the locking device can only be moved when the lever from its first in his other, in particular in its final position, has been strigwen kt. Before a shift of the locking device is not possible.
  • the lever When the lever has been pivoted from its first to its further position, it actuates the rocker element, so that after reaching this further position, the free end of the at least one lever element is released. By this release, now the locking device can be moved, thereby making it possible that the free end of the at least one lever element and thus a part of which can dip into the associated receiving space of the lever. After completion of this sliding operation, the locking device is in its further position and thus sets the lever, ie, that it can not be pivoted from its second position taken back into its first position. At this point, it can be thought that the lever, in particular its at least one receiving space, and / or the locking device are designed and matched to one another so that the lever can be swiveled back a little bit.
  • This pivoting back has the advantage that the lever no longer acts on the rocker element and this is relieved.
  • the at least one lever element whose part is immersed in the receiving space of the lever, also relieved and is thus tension-free in the receiving space, but still blocked there is a further pivoting back of the lever.
  • This relief of the at least one lever element increases its service life, since material fatigue and external forces, for example in the form of vibrations, are avoided.
  • the fact that it is allowed that the lever from its further position, in particular its end position, may pivot a little way back, but not canceled by him caused first locking the mating connector in the connector.
  • the at least one entrainment geometry of the lever is designed with respect to the associated geometry of the mating connector such that it experiences no effect despite the piece being pivoted far backwards of the lever.
  • a receiving geometry for the locking device is arranged on the housing, which forms a stop geometry for the respective lever element.
  • the sliding locking device is permanently and captively secured to the housing.
  • the receiving geometry of the housing and the corresponding geometry of the locking device can be coordinated so that they come into contact with each other when the locking device has been moved for secondary locking of the lever.
  • a path barrier which can be perceived in particular by haptics, takes place during the displacement operation of the locking device for the purpose of secondary locking.

  • a cooperating with the connector 1 mating connector is available to form the connector, but not shown for the sake of clarity.
  • FIG. 1 and 2 the individual components of the connector 1 are shown.
  • This has a housing 2 whose geometry is only an example.
  • a contact carrier 3 is arranged, wherein housing 2 and contact carrier 3 are integrally formed or form two separate and interconnectable elements.
  • the contact carrier 3 has at least one contact chamber 4.
  • eight contact chambers 4 and in the upper row twelve contact chambers 4 are arranged in the lower row.
  • the arrangement in two rows and the number is only an example. There may also be more or fewer than the illustrated contact chambers 4. Also, only one row or more than two rows of contact chambers 4 may be present.
  • the Flebel 5 pivotally a Flebel 5 with a handle protection 6, which is optional for the purpose of better Flandhabung arranged.
  • the Flebel 5 each side of the housing 2 pivot points and has a driving end geometry 7 for a corresponding geometry (such as a pin) of the mating connector on the end.
