The conversion of the power network system voltage from 14 VDC to 42 VDC is accompanied by a discontinuous change of arcing energy produced during live intentional or accidental unplugging. It leads to an adaptation of the electrical breaking and connecting devices. For the connectors, it results in adding the capability of withstanding the arcing during live disconnection to the basic ones of high conduction and low insertion effort. To quantify this new capability and the correlated level of arc damage, the authors propose a global result that links the insertion criteria "insertion force" to the global arc parameter "arc energy". They put forward three zones of arc damage delimited by arc energy threshold values. As an extension of this result, the outline of an evaluation method of arc damage on connector is proposed. As intermediate results, the influence of the opening speed on the arc energy increasing is confirmed. Moreover, the influence of the erosion mechanism on the conduction behavior of the contact is investigated. To conclude, a short review of the different connector concepts is presented.
