  • One way of increasing the current-carrying capacity of plug and cable connections is cooling, in particular active cooling of load contacts and lines.
  • cooling in particular active cooling of load contacts and lines.
  • connectors with integrated fluid cooling of the load contacts and charging cables with integrated cooling of the load lines are used.

  • a cooling module for a connector part in which that section of an electrical load cable that is electrically connected or connectable to the connector can be actively cooled.
  • This makes it possible to actively cool the load cable over its entire length, which means that, for example, the cross-section of the load cable can be reduced overall while the current carrying capacity remains the same. This enables high currents with reduced weight at the same time.
  • the connection of the electrical load line can be fully integrated into the coolant circuit, it is therefore not necessary to separate the cooling circuit from the electrical load line.
  • the connector part can be a high-current and/or high-voltage connector part.
  • the connector part is designed to conduct electrical currents with a power of 10 kW or more, in particular 50 kW or more, 135 kW or more, or 350 kW or more.

  • the recess is accessible via an access opening which is arranged separately from the opening for the coolant.
  • the access opening can be closed by the cover.
  • the electrical load line can first be connected to the connection area, whereupon the recess can then be closed by the cover.
  • the cover is e.g. screwed to the base body.
  • the lid comprises or consists of a plastic, which enables a further weight reduction.
  • a hose connector can be mountable or mounted at the opening, e.g. by means of a screw thread. This allows easy and safe installation.

  • An electrical load line that makes electrical contact with the connection area can be electrically connected to an electrical load contact to be mounted on the mounting surface via the material of the base body. This enables a particularly good electrical connection of the load contact to the load line.
  • the load contact is designed, for example, to be plugged into a counter-load contact.
  • the base body can be designed in one piece.
