Title: PLUG CONNECTOR PART HAVING COOLED CONTACT ELEMENTS FOR CHARGING ELECTRICAL VEHICLES
Abstract:
A plug connector part (1) comprises a plug section (100, 101) for plugging connection to an associated counter plug connector part (40), and at least one contact element (11A, 11B) which is arranged on the plug section (100, 101) and has at least one electrically conductive contact section (111) for plugging connection to an associated counter contact element (41) of the counter plug connector part (40), and a shaft section (110) connected to the contact section (111) for securing an electrical line (20) to the contact element (11A,11B). In addition, a casing element (15) is provided which can be attached to the shaft section (110) of the at least one contact element (11A, 11B), and which has a body (150), a plug opening (158) formed in the body (150) for receiving the shaft section (110) and a cooling channel (159) formed in or on the body (150) and extending around the plug opening (158) for conducting a coolant. In this way, a plug connector part is provided which can provide an active cooling for a contact element in order to achieve a high current load capacity in spite of a comparatively small-dimensioned contact element.
