Definitions

  • the present invention relates to an electrical high power connection assembly, in particular for the connection of high power electrical cables to electrical devices, such as further high power cables or high power batteries, especially in the field of hybrid or electrical vehicles.
  • electrical cables of large cross section may be required. Since such relatively thick electrical cables are usually relatively stiff, movement and bending of such cables, upon assembly for example of a car wire harnesses, can create large forces acting on components connected to the cables. Such cable movement can result in twisting forces, i.e. forces causing a turning movement of the connector components.
  • the corresponding connectors have to be constructed such that they can withstand these forces, in particular twisting forces, without becoming disconnected from corresponding counter connectors. Since space in an engine compartment of an electrical or hybrid vehicle is usually very limited. At the same time, the electrical connectors also need to be sufficiently compact.
  • an electrical connector assembly is described in document DE 198 02 554 A1 .
  • an electrical connector assembly is described comprising a connector housing and a mate assist slider, which assembly is adapted to be connected to a corresponding counter connector.
  • the mate assist slider of the electrical connector assembly is provided with suitably angled cam slots which are adapted to receive corresponding cam pins of the counter connector housing.
  • the mate assist slider Upon mating the connector assembly to the counter connector, the mate assist slider is moved from an open position to a closed position, wherein the cam pins move along the angled cam slots. This movement of the cam pins along the angled cam slots results in a force which acts on the counter con- nector housing, causing the same to move towards the connector assembly, thereby facilitating the mating process.
  • an electrical connector assembly is described in document EP 2 312 705 A1 .
  • an electrical connector assembly is described comprising a housing and a mate assist slider, the electrical connector assembly being adapted to be mated to a corresponding counter connector.
  • cam pins of the counter connector housing are mounted resiliently, such that upon mounting the counter connector to the electrical connector assembly, the pins are deflected by corresponding tapered inserts of the cam slots of the mate assist slider.
  • the mate assist slider is moved out of the connector housing, such that, due to a movement of the cam pins along suitably angled cam slots, a force acts separating the connector assembly and the counter connector.
  • an electrical connector assembly which is adapted to be mated with a counter connector and which, preferably comprises the counter connector.
  • the electrical connector assembly com- prises a connector housing and a mate assist slider.
  • the mate assist slider is arranged moveable between an open position and a closed position on the connector housing.
  • the mate assist slider comprises at least one cam slot which is adapted to receive a corresponding cam pin of the counter connector which can, for example, be a corresponding cable connector or a connector of an electrical battery, for example of an electrical or hybrid vehicle.
  • the electrical connector assembly is adapted to transmit an electrical power of at least 10 kW, more preferably of at least 50 kW, even more preferably of at least 100 kW and most preferably of at least 150 kW.
  • the electrical connector assembly is for example adapted to transmit a current of 100 ampere at a voltage of 100 volts, and thus a high electrical power of 10 kW.
  • the counter connector is provided with a corresponding cam pin such that, upon mating the counter connector and the connector housing of the electrical connector assembly, the cam pin is received by the cam slot.
  • the cam slot is thus moved relative to the cam pin, such that, due to an interaction of the cam slot and the cam pin, a lever like force acts onto the cam pin.
  • the cam slot can be inclined with respect to a moving direction of the mate assist slider from the open position towards the closed position by a suitable angle, such that, due to the relative movement of the cam slot with respect to the cam pin, a lever-like force acts and the cam pin is pulled towards the connector housing.
  • the mate assist slider comprises at least one first twist prevention member which is adapted to interact with at least one second twist prevention member of the counter connector when the connector housing is mated with the counter connector and the mate assist slider is placed in the closed position.
  • the first twist prevention member and the second twist prevention member are adapted to prevent a movement of the counter connector with respect to the connector housing, in a direction essentially perpendicular to the moving direction of the mate assist slider from the open position towards the closed position.
  • perpendicular indicates an angle of 90° +/- 20°, preferably +/- 10°, even more preferably +/- 7,5° and most preferably +/- 5°.
  • parallel has to be understood in a corresponding sense as the term “perpendicular” within such typical tolerances.
  • the first twist prevention member and the second twist prevention member are adapted to prevent a movement of the counter connector away from the connector housing, when the connector housing is mated with the counter connector and the mate assist slider is placed in the closed position.
  • the first twist prevention member and the second twist prevention member provide a separate locking mechanism between the mate assist slider and the counter connector.
  • the mated position is additionally secured against the action of vibrations as they can occur upon operation of an en- gine or upon movement of an electrical or hybrid vehicle equipped with the electrical connector assembly.
  • one of the first twist prevention member and the second twist prevention member is a twist prevention latch.
  • one of the first twist prevention member and the second twist prevention member is a twist prevention recess which is adapted to receive the twist prevention latch.
  • the first twist prevention member i.e. the twist prevention member provided at the mate assist slider
  • the second twist prevention member i.e. the twist prevention member provided at the counter connector
  • Such the first twist prevention member and the second twist prevention member are ideally designed to provide the additional locking mechanism between the mate assist slider and the counter connector, since they are ideally designed to prevent a movement of the counter connector away from the connector housing, in particular, in combination with the locking mechan- ism provided already by the mate assist slider and the cam pin.
  • the mate assist slider comprises two side walls, a bottom wall and a back wall.
  • the back wall is positioned closest towards a cable connected to the connector assembly.
  • the mate assist slider has an essentially open box shaped form.
  • the mate assist slider is preferably provided on outer faces of the connector housing and thus, due to the essentially open box shaped form, preferably completes the outer surface of the connector housing, when placed in the closed position.
