Abstract: In one embodiment, an anti-rotation device is designed to prevent de-coupling of an electrical connector pair. The connector pair includes (i) a first electrical connector having a barrel with male threads formed thereon and (ii) a second electrical connector having a nut with female threads formed therein that mate with the male threads of the first connector. The anti-rotation device includes a barrel-locking portion connected by an interconnecting portion to a nut-locking portion. The barrel-locking portion engages the barrel of the first electrical connector to prevent rotation of the anti-rotation device circumferentially around the barrel. The nut-locking portion engages the nut of the second electrical connector to prevent the nut from rotating and backing out. The anti-rotation device inhibits rotation of the nut relative to the barrel, thereby preventing de-coupling of the second electrical connector from the first electrical connector.

Abstract: An enclosure according to this invention comprises a thermally conductive wall mountable to a heat source. The enclosure is mounted such that heat transfers from the heat source to the thermally conductive wall. A bracket holds the item to be heated to at least one of the walls of the enclosure, such that the item is warmed by thermal conduction. A thermal pad may be interposed between the item and the mounting wall and, likewise, between the enclosure and the heat source. By this structure, heat is passed from the heat source to the enclosure and then to the item.
