Current-carrying lead and plug connector having such a current-carrying lead

A plug connector comprising:

• at least one current-carrying lead comprising at least two litz wires and further comprising an electrical insulation partially surrounding the at least two litz wires, wherein the electrical insulation comprises at least one reservoir that is closed off by at least one plunger and contains an electrically insulating sealing medium, wherein the at least one reservoir comprises at least one outlet nozzle and wherein the at least one plunger is configured to force the sealing medium through the at least one outlet nozzle into at least one sealing space adjacent to the at least one reservoir;
• at least one sealing device for the current-carrying lead, wherein the at least one sealing device comprises at least one sealing body comprising at least one elastically deformable sealing part comprising a first conical surface;
• at least one wedge slider provided with a second conical surface interacting with the first conical surface of the at least one elastically deformable sealing part;
• a securing part that axially secures the sealing body;
• wherein, by applying a force that is acting in a longitudinal direction of the current-carrying lead on the at least one wedge slider, the at least one elastically deformable sealing part is elastically deformed transversely to the longitudinal direction against the current-carrying lead;
• wherein the at least one wedge slider is guided in the securing part;
• and
• wherein the at least one wedge slider is pre-tensioned axially in the longitudinal direction by at least one pressure spring element actuatable by at least one pressure member.

A plug connector comprising:

• a current-carrying lead;
• a strain relief device providing a multi-point support for the current-carrying lead;
• wherein the strain relief device comprises a first pair of pressure members oppositely positioned relative to each other and further comprises a second pair of pressure members oppositely positioned relative to each other;
• wherein the first pair of pressure members are positioned angularly relative to the second pair of pressure members;
• wherein the first pair of pressure members and the second pair of pressure members are linked to each other such that the second pair of pressure members are forcibly guided by the first pair of pressure members;
• two pressure springs arranged between the first pair of pressure members.
