Abstract
Exemplary contact backings for vacuum interrupters are described.
Claims31
An electrode assembly of a vacuum interrupter, comprising:
- an electrical contact;
- a coil conductor;
- and
- a conductive circular member disposed between the electrical contact and the coil conductor, the conductive circular member comprising
- a first portion defined by a first diameter and a second diameter, the second diameter being larger than the first diameter and being substantially equal to an outside diameter of the coil conductor, the outside diameter of the coil conductor defining at least a portion of an outer periphery of the electrode assembly, and
- a second portion defined by the second diameter and a third diameter, the third diameter comprising a largest diameter of the circular member, the third diameter being larger than the second diameter and being substantially equal to an outside diameter of the electrical contact,
- wherein a cross-section of the second portion has a thickness that is greater than a thickness of a cross-section of the first portion.

An electrode assembly of a vacuum interrupter, comprising:
- an electrical contact;
- a coil conductor comprising a longitudinal axis that extends substantially perpendicular to a diameter of the coil conductor;
- and
- a contact backing disposed between the electrical contact and the coil conductor, the contact backing comprising a portion that extends in an axial direction outside the diameter of the coil conductor such that the portion of the contact backing surrounds at least a longitudinal portion of the coil conductor, the axial direction being substantially parallel to the longitudinal axis of the coil conductor, the portion of the contact backing defining at least a part of an outer periphery of the electrode assembly,
- wherein one of the contact backing and the coil conductor comprises a notch in which at least a portion of a protrusion of the other of the contact backing and the coil conductor is disposed.
