Abstract
A switching device has an improved fastening arrangement to join an electrical insulating body with a conductive metal mounting piece or flange. The fastening arrangement involves a plurality of standard hardware fasteners. The quantity of fasteners required to join the insulating body and flange is dependent upon the desired strength of the joint and the size (or diameter if the insulating body is tubular shaped) of the insulating body.
Claims35
An electrical switching device disposed between a pair of conductors, the device comprising:
- a conductive switching portion for carrying current between the pair of conductors having one or more conductive mounting pieces wherein the conductive mounting piece has an interior surface and an exterior surface;
- an insulating body that comprises an interior surface defining a hollow interior and an exterior surface, and one or more ends wherein a portion of the interior or exterior surface of the conductive mounting piece contacts a portion of the hollow interior or exterior surface of the insulating body;
- and
- a plurality of fasteners securing one or more ends of the insulating body and the conductive mounting piece together, thereby forming a reversible joint capable of disassembly and reassembly therebetween.

An electrical switching device disposed between a pair of conductors, said device comprising:
- a switching, conductive portion for carrying current between said pair of conductors comprising a movable contact assembly and a stationary contact assembly wherein the movable contact assembly and the stationary contact assembly have at least one conductive flange with an exterior surface and an interior surface;
- a insulating tube disposed between the movable and stationary contact assemblies and having an interior surface, and an exterior surface, and one or more ends wherein a portion of interior surface or exterior surface of the insulating tube contacts a portion of the exterior surface or the interior surface of the conductive flange at one or more ends of the insulating tube;
- and
- a plurality of fasteners that engage the insulating tube and conductive flange such that the insulating tube and conductive flange are coupled together.
