“…Designs at the component level include: incorporating magnetic blast fields perpendicular to the arc [1], [3], [5], high disengagement speeds [1], [2], passive air flow directed to the arc through a small channel in the connector body [6], sacrificial contacts [7], and gassing polymers adjacent to the arcing terminals [1], [2]. The latter design builds on the technique of increasing the arc voltage by gas flow from thermally decomposing insulating walls [8]- [10].…”

Although connectors are generally not designed to disconnect electrical loads under power, in some circumstances they are mated and unmated under load. For instance, during repairs, diagnostic procedures, or when blown fuses are replaced under short circuit conditions. At dc system voltage levels significantly higher than the minimum arc voltage of metals such hot-disconnections may impact the reliability of the connection, the electrical distribution system, and automotive safety. Gassing polymers mounted onto connector terminals may reduce the damage resulting from disconnections under dc loads, and therefore enable connector designs with occasionally (forward running) arcing terminals.The authors discuss the effects of different types of gassing polymers on arc extinction and connector damage of standard automotive connectors.

“…In spite of total arc suppression being unrealistic; its reduction is envisaged and can be achieved by various methods (polymer out gassing [10,11], magnetic blowing [16], materials [17], etc…). The obtained results recommend than arc reduction effort should be focused on the second and mainly on the third zone.…”

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. This necessitates a modification of electrical breaking and connecting devices. For the connectors, it results in adding the capability of withstanding arcing during live disconnection to the basic characteristics of high conduction and low insertion effort. To quantify this new capability and the correlated level of arc damage, the authors propose to correlate the insertion criteria "insertion force" with the parameters "arc energy" and current level. Compared with our previous work, the introduction of the current parameter allows us to attribute the origin of the damage to the connector to the overheating of the contacts by heat conduction mechanisms supplied by the arc. As intermediate results, the influence of the opening speed and the contact coating on the arc energy increase is confirmed. The obtained results will help to characterize and to select arcresistant interconnection solutions in the field of the high power automotive applications.
