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.
  • a difficulty which arises, for example, upon assembling corresponding wire harnesses is that bending of such cables is relatively difficult.
  • an electrical high power connection assembly is described in the European patent EP 0 858 128 B1 . Therein, an electrical high power connection assembly is described comprising one-piece rectangular contact terminals which are placed inside of a connector housing.
  • the contact terminals described therein are produced as a single solid piece by means of a die cast procedure.
  • the contact terminals are provided with a female terminal portion with a plurality of contact springs for the reception of a contact pin of an electrical device.
  • the contact terminal is provided with a press fit portion for the reception of a contact pin of a further electrical device.
  • a rectangular contact terminal for high power applications which consists of a connection member and a terminal element, wherein the terminal element can be press-fittingly inserted into an opening of the connection member, thereby forming the rectangular contact terminal.
  • the connector housing consists in two housing halves. Upon assembly of the high power connection assembly, in a first step, the rectangular contact terminals are inserted into a first housing half along a first insertion direction. In a further step, the second connector half, including corresponding counter terminal elements, is mated to the first connector housing half, wherein the terminal elements and the counter terminal elements are connected. Due to the insertion of the rectangular contact terminals into the first connector housing half, this connector housing half needs to be of relatively large construction.
  • an object of the present invention to provide an electrical high power connection assembly which allows to be assembled more easily and which is less susceptible to incorrect assembly. It is a further object of the present invention to provide an electrical high power connection assembly which minimizes the required installation space, while, at the same time, it allows to be used for high power electrical applications such as in the field of hybrid or electrical vehicles. Further, it is an object of the present invention to achieve all the above advantages with an inexpensive product, whereby the electrically conductive components can be preferably made from sheet metal.
  • an electrical high power assembly which comprises a connector housing with a first reception cavity which defines a first insertion direction and a second reception cavity which defines a second insertion direction.
  • the first insertion direction and the second insertion direction are essentially perpendicular to each other.
  • the term "essentially” indicates that expressions, such as perpendicular or 90°, are not to be understood in a strict mathematical sense but within the typical production tolerances.
  • perpendicular as well as 90° both, indicate an angle of 90° +/- 20°, preferably +/- 10°, even more preferably +/- 7,5° and most preferably +/- 5°.
  • the electrical high power connection assembly further comprises a connection member, which is adapted to be at least partially inserted into one of the reception cavities of the housing.
  • connection member is preferably an essentially right-angle bracket, or 90° angle bracket, comprising two essentially perpendicular terminal fastening portions, whereby each terminal fastening portion comprises an opening adapted to receive one terminal element, such that each of the terminal elements is oriented essentially along one of the insertion directions of the connector housing, when the terminal elements are received by the openings of the connection member and the connection member is positioned inside of the connector housing.
  • the two terminal elements are preferably each adapted to be electrically connected to a contact member of an electrical device, such as an electrical power supply or an electro motor as used in electrical or hybrid vehicles.
  • an electrical device such as an electrical power supply or an electro motor as used in electrical or hybrid vehicles.
  • At least one of the terminal elements is adapted to be press- fittingly connected to one of the terminal fastening portions.
  • connection member may for example be provided already placed in a pre-assembled position, e.g. inside of the connector housing, when the components of the electrical high power connection assembly are delivered to the harness maker.
  • the harness maker is thus only required to insert the corresponding part of a contact member of an electrical device into the respective reception cavities of the connector housing.
  • the electrical high power connection 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 high power connection assembly is for example adapted to transmit a current of 100 ampere at a voltage of 100 volts, and thereby a high electrical power of 10 kW.

  • ⁇ Fig. 2 shows an exploded perspective view of the assembly of Fig.
  • Figs. 3 to 6 show different embodiments of connection members adapted to be used in the assembly of Fig. 1 . It should be noted that, on figures, structural and/or functional elements which are common to different embodiments may have the same reference sign. Thus, unless otherwise stated, these elements have structural, dimensional and material properties which are identical. Figs. 1 and 2 illustrate a preferred embodiment of an electrical high power connection assembly.
