摘要： An electrical cord clamp is disclosed for securing an end of an electrical cord to an electrical device or connector. The electrical cord clamp provides strain relief between the ends of the electrical conductors of the electrical cord and the terminals of the electrical device or connector. The cord clamp has a pair of clamping members tiltably coupled to a pair of housing halves of the electrical device for tiltably engaging the electrical cord upon installation thereon to pull the electrical cord towards the terminals of the electrical device or connector. One or more spring elements are preferably provided for normally biasing the clamping members to their original position prior to assembly within the electrical device or connector. In one embodiment, the spring elements are integrally formed with the cover halves. In other embodiments, clamping members are provided with one or more spring elements or arms.

摘要： An auxiliary switch for a circuit breaker of the split case type. The switch is capable of switching the rated interrupt current capacity of the breaker and is fitted in to the circuit breaker case so that the overall width is substantially equal to or less than the overall width of the circuit breaker. Several embodiments of the auxiliary switch disclose various features which contribute to increasing the interrupt current rating and/or down sizing the width of the auxiliary switch. Among them are: an early make, late break of the auxiliary contacts compared to the circuit breaker contacts; an inertia dampening fly wheel attached to the actuator of the switch to enhance the early make/late break feature; a wiping action between the moveable and stationary contacts of the auxiliary switch to clean off welding and debris deposited from arcing; dual auxiliary contacts to enhance the contact area with little impact on package size and width; and a positioning of the auxiliary actuator on the contact lever of the circuit breaker to prevent the spring forces acting on the actuator from affecting circuit breaker contact pressure.

摘要： A circuit breaker which has an auxiliary coil fitted onto the primary bobbin adjacent the pole piece having a dielectric auxiliary bobbin and a dielectric bobbin housing encapsulating the auxiliary coil and forming an encapsulated auxiliary coil assembly. Both the dielectric auxiliary bobbin and the dielectric bobbin housing are comprised of a polymeric material, preferably a liquid-crystal polymer. Preferably, the liquid-crystal polymer is an aromatic liquid-crystal polyester which is reinforced with about 30% glass and has a nematic liquid-crystal structure. Furthermore, it is preferred for the dielectric strength of the liquid-crystal polymer to be about 32 KV/mm to about 35 KV/mm.
