Abstract

A plug-in connector part for connection to a mating plug-in connector part includes: a housing which has a plug-in portion for plug-in connection to the mating plug-in connector part; at least one contact element arranged on the plug-in portion and for electrically contacting an associated mating contact element of the mating plug-in connector part; a thermal conductor line connected to the at least one contact element; and a cooling body arranged in the housing and thermoconductively connected to the at least one contact element via the thermal conductor line in order to dissipate heat from the at least one contact element.

Claims

1. A plug-in connector part for connection to a mating plug-in connector part, comprising:

a housing which has a plug-in portion for plug-in connection to the mating plug-in connector part;

at least one contact element arranged on the plug-in portion and configured to electrically contact an associated mating contact element of the mating plug-in connector part;

a thermal conductor line connected to the at least one contact element; and

a cooling body arranged in the housing and thermoconductively connected to the at least one contact element via the thermal conductor line in order to dissipate heat from the at least one contact element,

wherein a first end of the thermal conductor line is plugged into an opening in a metal connecting piece and is connected to the associated contact element via the connecting piece.

2. The plug-in connector part according to claim 1, wherein the plug-in connector part has a plurality of contact elements arranged on the plug-in portion, each contact element being associated with a cooling body that is thermoconductively connected to the associated contact element via the thermal conductor line.

3. The plug-in connector part according to claim 1, wherein the thermal conductor line and/or the cooling body are comprised of metal.

4. The plug-in connector part according to claim 1, wherein a second end of the thermal conductor line is plugged into an opening in the cooling body.

5. The plug-in connector part according to claim 1, wherein the cooling body has a fluid channel through which a coolant can flow.

6. The plug-in connector part according to claim 1, wherein the cooling body has two fluid channels which are fluidically interconnected via a deflection line connected to the cooling body.

7. The plug-in connector part according to claim 1, wherein a fluid channel of a first cooling body associated with a first contact element is connected via a deflection line to a fluid channel of a second cooling body associated with a second contact element.

8. The plug-in connector part according to claim 7, wherein a first coolant line that is guided in a cable connected to the plug-in connector part is connected to the first cooling body in order to supply a coolant, and a second coolant line that is guided in the cable is connected to the second cooling body in order to conduct away the coolant.

9. The plug-in connector part according to claim 1, further comprising a plurality of cooling bodies interconnected via a connecting element and held at distance from one another by the connecting element such that the cooling bodies do not touch one another.
