Abstract

A plug-in connector part for connection to a mating plug-in connector part includes: a contact element for electrically contacting an associated mating contact element of the mating plug-in connector part. The contact element includes a contact portion for contacting the mating contact element of the mating plug-in connector part and a shank portion for connecting a load line for transmitting an electrical current. The contact element includes a channel, which extends in the contact element and to which at least one coolant line is fluidically connectable, for guiding a coolant through the contact element.

Claims

1. An assembly, comprising:

a plug-in connector part for connection to a mating plug-in connector part, the plug-in connector part comprising a contact element configured to electrically contact an associated mating contact element of the mating plug-in connector part, the contact element comprising a contact portion configured to contact the mating contact element of the mating plug-in connector part and a shank portion configured to connect a load line for transmitting an electrical current, and

a cable that is connected to the plug-in connector part and guides the load line connected to the contact element and at least one coolant line,

wherein the contact element includes a channel, which extends in the contact element and to which the at least one coolant line is fluidically connected, the channel being configured to guide a coolant through the contact element.

2. The assembly according to claim 1, wherein the contact element comprises an integral body that forms the contact portion and the shank portion and in which the channel is formed.

3. The assembly according to claim 1, wherein the shank portion is cylindrical.

4. The assembly according to claim 3, wherein the channel extends coaxially to the shank portion.

5. The assembly according to claim 1, wherein the channel comprises a first end to which a first coolant line is fluidically connectable, and a second end to which a second coolant line is fluidically connectable, the channel being configured to guide the coolant between the first end and the second end.

6. The assembly according to claim 5, wherein the contact element comprises an attachment connector that extends radially inside the shank portion and to which the first coolant line is connectable for fluidic connection to the channel.

7. The assembly according to claim 5, further comprising a connecting element that is attached to the contact element, is fluidically connected to the channel, and to which the second coolant line is connectable for fluidic connection to the channel.

8. The assembly according to claim 1, wherein the load line comprises an electrically conductive line casing, and the at least one coolant line is guided coaxially inside the line casing.

9. The assembly according to claim 8, wherein the line casing is pushed onto the shank portion of the contact element such that the line casing peripherally surrounds the shank portion at least in part.

10. The assembly according to claim 8, wherein the at least one coolant line that is guided coaxially inside the line casing is connected to the contact element such that the at least one coolant line is fluidically connected to the channel of the contact element.

11. The assembly according to claim 8, wherein a further coolant line is guided in the cable, which further coolant line extends outside the load line and is connected to the contact element such that the further coolant line is fluidically connected to the channel.
