Latest Patents

Fred Erb's latest patents include "Floating Jaw Retention Springs for a Switch" and "Contactor Having a Z-Shaped Current Path for Blow-Out Force Reduction." The first invention solves the problem of loss of contact between the jaws of a stationary contact with a switchblade of a knife switch during lateral motion. This is particularly important under conditions such as short circuits, where electromagnetic forces can disrupt contact. The design features a base, a pair of electrically conducting jaws, and retention springs that maintain electrical contact even when the switchblade moves laterally.

The second patent focuses on reducing electromagnetic forces that tend to open contacts in an electromagnetic contactor. By providing a current flow path with a specific geometry, the invention minimizes the forces acting on the movable contact. This design includes a frame, stationary and movable contacts, and a flexible link that allows for partial cancellation of magnetic forces, thereby improving the reliability of the contactor.
