Definitions

  • the present invention relates to the technical field of electronics and more particularly to an electrical connector for a power electronics circuit, such as, for example, a power electronics circuit for an electric motor vehicle compressor.
  • the invention also relates to an electronic circuit comprising said electrical connector.
  • the use of electronic circuits in motor vehicles improves comfort and safety of use.
  • the electronic circuits can be previously housed in electronic modules which are then mounted inside the vehicle in dedicated housing. Once mounted, each electronic module is connected to the vehicle's electronic circuit via a connection interface present on its surface.
  • the connection interface is standardized to allow rapid connection of the electronic module to the electronic circuit of the vehicle.
  • the electronic module comprises electrical conductors for connecting the electronic circuit or circuits present in the electronic module to the connection interface.
  • the electrical conductors are generally electrical son whose first ends are welded for example on the printed circuit of the electronic circuit.
  • the flexibility of the electrical wires facilitates the connection of their second end to the connection interface, when the electronic circuit is maintained in the electronic module.
  • the vibrations induced by the rolling of the vehicle spread to all components of the vehicle, including electronic circuits and electrical wires. At these electronic circuits and electrical wires, the vibrations generate mechanical stresses that can in turn cause a break between the electrical wires and the printed circuit. According to another drawback, the vibrations of the vehicle can also cause the wire to hit the components present on the printed circuit and damage them.
  • the present invention proposes an electrical connector for a printed circuit comprising a support holding a connection element arranged to crimp a plug-type electrical connector.
  • the invention is characterized in that the support extends beyond the connecting element so as to form at least two plates, each plate supporting at one distal end one or more appendages extending at least partly in a direction opposite to that of the connecting element, the appendage (s) being intended to fit into a housing formed in the printed circuit.
  • the present invention provides an electrical connector for a printed circuit comprising a support holding a connection element arranged to crimp an electrical connector of the type of a RADSOK plug.

  • Each appendix is arranged to sink into the thickness of the printed circuit to ensure a better resistance to shear stresses between the electrical connector and the printed circuit.
  • the invention allows a better maintenance over time of the electrical connector on the printed circuit.
  • the electrical connector acts as a junction between the printed circuit and an electrical wire connected to a connection interface as described above.
  • the electric wire is not only soldered on the printed circuit but it is also crimped at the connection element.
  • the electrical connector can be configured so that its connection element is sufficiently far from the surface circuit board to limit the risk of contact between the electrical wire and the components on the printed circuit.
  • the electrical connector comprises several appendices for maintaining it on a printed circuit. Unlike a wire, it is not likely over time to hit other components on the printed circuit board.
  • the electrical connector according to the invention is more rigid than a single electrical wire, although maintaining a certain flexibility as will be demonstrated in the paragraphs below. Therefore, it is not necessary to cover the electrical connector with an insulating sheath to avoid a short circuit between the electrical connector and the other components. Thus, the connection of the conduction element with a printed circuit is made simpler and faster to implement than for an electric wire.
  • the plates extend radially with respect to the connection element. This allows in particular to minimize the size of the electrical connector in a direction normal to the surface of the printed circuit.

  • At least two plates are aligned so as to maintain the connection element above the printed circuit. More particularly, a first plate is located on a first side of the connection element and a second plate is located on a second side of the connection element, the first side being located opposite the second side by relative to the connection member, the first and second platen being collectively aligned with the connecting member.
  • the electrical connector may include several plates for the same purpose.
  • the electrical connector may comprise several plates arranged regularly or not around the connection element.
  • the support comprises an upper face vis-à-vis the connection element and a lower face vis-à-vis one or more appendices.
  • the connection element is positioned above the support while the appendages are arranged below said support.
  • At least one of the appendices of one or more of the plates is located at a lateral edge of the corresponding plate.
  • a plate has at least one appendix at two opposite side edges, to ensure a better stability of the platen vis-à-vis the printed circuit and reduce the risk of tearing.
  • At least one of the appendages of one or more of the plates is located at an edge delimiting the distal end of the corresponding plate.
  • distal means the end of a plate which is furthest from the connection element.
  • proximal is used below to refer to the end of a platen near or in contact with the connecting member.
  • the appendages are located closest to the distal end of a plate to allow the electrical connector to have greater flexibility vis-à-vis the printed circuit.
  • the electrical connector provides greater tolerance for crimping a plug-type electrical connector or an electrical wire having at one end a plug.
  • the flexibility of the plates makes it possible to damp the vibrations of the plug in order to preserve the printed circuit of said vibrations.
  • At least one of the appendages comprises an end of elongation perpendicular or substantially perpendicular to the corresponding plate to allow its anchoring in a corresponding opening of the printed circuit, for example by crimping.
  • crimping is completed by a solder or solder between at least one conductive portion of the printed circuit and at least a portion of the perpendicular or substantially perpendicular elongation end.
  • an end of at least one appendix is connected to the corresponding plate by means of a curved portion.
  • the curved portion promotes a preferred deformation of the appendix when a stress is exerted on the electrical connector. This alternative also provides greater flexibility of the electrical connector vis-à-vis the printed circuit.
