Electrical circuit protection device with high resistive bypass material
A fuse suitable for arc quenching is disclosed. The fuse incorporates a high-resistive material or element placed in parallel relationship with the fusible element to mitigate, minimize and/or prevent arcing during an overcurrent condition. By incorporating a high-resistive material or element in parallel with a fusible element an alternate or second path for current flow during an overcurrent condition is provided. As such, during normal operating conditions, current travels through the fusible element. However, during an overcurrent condition, the resistance through the fusible element increases. Once the resistance through the fusible element is greater than the resistance through the high-resistive material or element, the current will bypass the fusible element and travel through the high-resistive material or element. In this manner, arcing through the fusible element during the overcurrent condition can be prevented or minimized.

Wire nut (lug) fuse holder combination
A device is provided for use with an electrical apparatus. The device comprises a wiring lug having a side and a base configured to receive a mounting screw. The wiring lug is configured to connect with a wire. The device further comprises a shaped spring configured to apply a force to a fuse for maintaining an electrical connection between the fuse and the wiring lug thus eliminating a separate electrical bus part that in a typical installation would pass a current from a conductive fuse clip to the wiring lug. The shaped spring provides a fuse clip with one side defined by the shaped spring and other side defined by the side of the wiring lug to contact a ferrule on the fuse or contact a blade extending from the ferrule on the fuse.
POWER DISTRIBUTION CLIP ASSEMBLY
A power distribution assembly which may be a fuse clip or a switch includes a lug mounted to a block in association with a spring clip which confronts one side of the lug. A portion of the spring clip is mounted to the block and an upper spring arm of the clip is positioned on one side of the lug. The lug is mounted to the block and includes a downwardly projecting tang which is inserted through a slot in the bottom portion of the assembly to thereby couple the spring arm to the lug and block and to receive the end of the fuse or a blade between the spring arm and the lug.
HIGH VOLTAGE COMPACT FUSE ASSEMBLY WITH MAGNETIC ARC DEFLECTION
Fuse assemblies in the form of fuse blocks and fuse holders include embedded permanent magnet arc suppression features that facilitate higher voltage operation of fusible circuit protection without increasing the size of the fuse assemblies. The embedded magnets apply an external magnetic field upon an overcurrent protection fuse and produce an arc deflection force to enhance arc quenching capability of the fuse without increasing its form factor.
CONNECTOR
A connector includes a housing body, a shield shell that externally covers the housing body, a first connection terminal that is housed in the housing body, electrically connected to a first wire in the housing body, and electrically connected to a counterpart terminal when the connector is connected to a counterpart connector, and a circuit protection component that is interposed, in the housing body, between the first connection terminal and the first wire, and connects the first connection terminal and the first wire in series to protect a circuit. The housing body includes at least one thermal conductor that performs thermal conduction with the circuit protection component by being in contact with the circuit protection component.
DUAL ELEMENT FUSE AND METHODS OF MANUFACTURE
A dual element electrical fuse includes at least one high overcurrent fusible element and a low overcurrent fusible element connected to one another inside a housing. The low overcurrent fusible element includes a single sided circuit board and a releasable conductive element that more simply provides low overcurrent protection and manufacturing efficiency with improved quality.
High voltage compact fuse assembly with magnetic arc deflection
Fuse assemblies in the form of fuse blocks and fuse holders include embedded permanent magnet arc suppression features that facilitate higher voltage operation of fusible circuit protection without increasing the size of the fuse assemblies. The embedded magnets apply an external magnetic field upon an overcurrent protection fuse and produce an arc deflection force to enhance arc quenching capability of the fuse without increasing its form factor.
Shielded connector
The present invention provides a shielded connector that can reduce the entire size thereof while preventing an increase in the number of components. A shielding shell includes a shell body provided to an outer side of a housing, and a thermally conductive holding member that supports an insulating container portion of a fuse, so the heat generated by the fuse is dissipated to outside, thereby reducing the space between the housing and the fuse and reducing the entire size of the shielded connector. Also, the shielding shell functions as both a heat dissipation member and a magnetic shield, thus, an increase in the number of components can be prevented.
