  • wiring or conductor harnesses which may consist by way of example of optical fiber cables, fluid conductors and/or electric cables.
  • electronic and optical systems have grown more complex and therefore increased the need for connectors including a plurality of terminals or poles.
  • a connector of the above-mentioned type is described for example in WO 2007/117533 A1 and in WO 2006/124127 A1 .
  • the shown electrical connectors comprise a lever which is connected pivotably to the housing of the connector.
  • the lever rotates within a range from a pre-engagement position to a final engagement position and has a recess configured to fit a protrusion arranged on a mating connector.
  • the lever includes a locking portion disposed on a beam thereof, having a latching detent to engage with an engaging portion of the housing in the engagement position of the lever.
  • US 6,648,667 B2 discloses a device for securing a first electrical connector mounted to an electronic module to a second electrical connector supported by a support structure.
  • the first electrical connector has a latch having a first and configured to engage the support structure and a lever portion to support a force on a first electrical connector. This force allows the first electrical connector to be urged towards the second electrical connector.
  • the connector is provided with a catch configured to secure the latch when the connectors are mated.
  • US 2006/0270257 A1 discloses a locking lever for a connector, each of the end parts of the lever having a cam track.
  • the locking lever can be pivoted into a position, in which one open end of each of the cam tracks can be positioned at a catch of the second plug part and a locking position in which each of the catches can be positioned in a locking portion of the cam track.
  • a groove extends along an end portion along the cam track to a allow for an elastic deformation, so that the catch can penetrate into the locking portion.
  • the elastic portion of the cam track comprises a recess for receiving the catch of the second pluck part, serving for locking the lever.
  • US 6,942,504 B2 and US 6,755,674 B2 also describe connector assemblies having a lever with a cam track. To lock the lever in a locking position, the shown levers are provided with resilient locking piece which engage with the housing of the connector.

  • the lever serves for rotating the pinion gear between a retain position at which the connector and the counter connector are next to each other and a release position at which the connector can be unmated.
  • a problem which arises in known connectors is that connectors can be released accidentally by external forces acting on the connector.
  • An external force can be exerted onto the connector, for example, through the housing or conductors connected to the connector.
  • the lever has at least one locking face, said locking face pointing substantially against the mating direction, the normal vector of the locking face passing the pivot axis on the locking face side of the lever.
  • An advantage of the solution is that external forces acting on the connector or wires connected to the connector, in particular forces which are directed at least partly against a mating direction of the connector, result in a closing force which holds the lever at the locking position or mating position, preventing the lever from pivoting into a release position. External forces acting on the connector are, at the locking position of the lever, transmitted through the locking face from the connector to a counter connector.
  • the position of the locking face side of the lever may depend on the mating direction or the guidance of the connector in relation to the counter connector.
  • the locking face side may be defined in relation to a plane, said plane comprising the pivot axis and extending in mating direction.
  • the resulting force affecting the locking face points to the pivot axis. Therefore, the resulting force can be divided up into two orthogonal forces: A holding force which has the direction of the normal vector of the locking face, and a closing force which points to a direction parallel or tangential to the locking face, said closing force pushing the lever in the direction of the locking position.
  • said lever is configured to transmit at the locking position a holding force from the connector to the counter connector, said holding force pointing substantially against the mating direction, the force vector of the holding force passing the pivot axis on the lever side.

  • the locking face and the counter locking face abut each other and transmit the external forces from the connector to the counter connector.
  • the holding force is realized by mating the locking face with the counter locking face, whereas the direction of the holding force corresponds to the normal vector of the counter locking face.
  • the lever may have a stop, said stop disposed to transmit at a release position of the lever an unmating force to the housing of the connector, said unmating force directed substantially against the mating direction.
  • the stop allows for using the lever as grip for pulling at the connector to unmate the connection.
  • the lever At the locking position of the lever, by pulling at the lever in a direction pointing against the mating direction the lever can be moved into the release position and serves as handle for disassembling the connection between the connector and the counter connector.
  • the connector can be unlocked and removed in one step by holding at the lever.
  • the lever can have at least one projection extending substantially in the mating direction and in the direction of the pivot, the locking face arranged at the projection.
  • the projection can extend into the housing of the counter connector, assuring the holding function of the locking face by disposing the locking face inaccessible from outside of the counter connector.

  • the window can be formed by an upper lever arm and to side arms, the upper lever arm and the side arms surrounding the conductors connected to the first and/or the counter connector.
  • the lever can form a closed frame.
  • the lever can be configured to abut an adjacent portion of the connector at the locking position and in a mating direction.
  • An advantage of this embodiment is that the adjacent portion of the connector provides a stop which clearly defines the locking position of the lever.
  • the connector can comprise guiding organs, the guiding organs extending in the mating direction and at least at a mating position of the connector engaging counter guiding organs of the counter connector, said guiding organs guiding the connector to the mating position.
  • the locking face and/or the counter locking face can be curved, the centre of the radius of curvature situated offset from the pivot in a direction pointing substantially against the mating direction and on the locking face side of the pivot.
  • a radius of curvature allows for reducing the distance between the locking face and the counter locking face without interfering the rotation of the lever from the release position to the locking position.

  • the centre C of the radius R is arranged offset from the pivot axis P, and has in a transversal direction T a distance X from the pivot axis P.
  • a movement of the connector 2 against the mating direction M at the locking position of the lever 5 may result from friction forces which are accidentally or unintentionally exerted on the wires (not shown) connected to the connector 2. If the connector 2 is moved upwards against the mating direction M, the locking face 9a of the lever 5 abuts the counter locking face 10a of the counter connector 3 at a touch point A. Irrespective of the direction of an external force exerted on the connector 2 or the counter connector 3, the connector 2 can at the mating position, due to the guiding protrusions 15, 16 and guiding recesses 13, 14 shown in Fig. 1 , only move against the mating direction M.
  • the lever Due to the connection to the pivot 4 the lever has a rotating degree of freedom allowing the lever 5 for rotating on the pivot axis P. Therefore, an external force which acts on the connector 2 and which is directed against the mating direction M results in a bearing force D.
