Abstract: A protective element includes a base substrate, a fusible conductor, a heater, and a heater-attached substrate. The base substrate has a first electrode and a second electrode formed thereon, the first electrode and the second electrode each being connected to an external circuit. The fusible conductor is supported on a first surface thereof by the base substrate and connected to the first electrode and the second electrode. The heater is configured to fuse the fusible conductor by generating heat. The heater-attached substrate has the heater provided thereon. The fusible conductor has one contact with the heater-attached substrate and the one contact is positioned on a second surface of the fusible conductor, which is an opposite surface to the first surface.

Abstract: A power connector includes a housing having a front wall including a socket configured to receive a power plug. The power connector includes an electrical component held by the housing being electrically connected to a power contact in the socket. The electrical component is a heat generating component. The power connector includes an EMI enclosure coupled to the housing. The EMI enclosure has walls defining a chamber. The housing, power contacts, and electrical component are received in the chamber. The walls of the EMI enclosure provide EMI shielding for the electrical component. The EMI enclosure includes a flap extending from a wall of the EMI enclosure into the chamber having a flap thermal interface thermally coupled to the electrical component to dissipate heat from the electrical component.

Abstract: A single bolt fuse assembly and method to connect a single bolt fuse to a circuit or device are disclosed. The single bolt fuse assembly enables the single bolt fuse to be used on any electrical device having a hole suitable for receiving a threaded shaft and connectable to a circuit or device that electrically connects to a female battery or power cable. The apparatus includes a separate high-conductive metal terminal that mates with the stud that mechanically attaches the fuse between the electrical devices. The stud is insulated to avoid becoming part of the electrical circuit and to ensure proper operation of the fuse. By mechanically attaching the stud to the metal terminal, the stud is unlikely to get separated from the fuse.
