摘要： A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element. A sensing element facilitates an electrical connection between the first and second electrodes. A flux material is provided around the sensing element. In a preferred embodiment, the flux contains a first component that is a polar material and a second component that is a non-polar material. A spring element exerts a force on the sensing element. The sensing element resists the force applied by the spring element. Upon detection of an activation, or fault, condition, the sensing element loses resilience and no longer resists the force exerted by the spring element, resulting in the spring element severing the electrical connection between the first and second electrodes. The flux allows the spring element to sever the electrical connection without dragging the sensing element.

摘要： A controller circuit for activating and deactivating an electrical power converter that provides power to a device includes power input terminals on a primary side, and power output terminals on a secondary side, which are configured to provide power to the device. The controller circuit includes a detection circuit configured to determine whether the device is connected and, if connected, causes power to be routed to the electrical power converter to activate the electrical power converter. When the device is not detected, the electrical power converter is deactivated until the device is reconnected.

摘要： An electrical device includes two electrodes and a conductive polymer layer, containing a mixture of a polymer and a conductive filler, separating the electrodes. A oxygen barrier material containing a thermosetting polymer component is present on the exposed surface of the conductive polymer layer that is not in contact with the laminar electrodes. The oxygen barrier material may be a polyamine-polyepoxide material, and may provide for acceptable barrier properties over a wide range of humidity levels.

摘要： A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element between the first and second electrodes. A sliding contact is connected by a sensing element to the first electrode, second electrode, and heater element, thereby bridging and providing a conductive path between each. A spring element is held in tension by, and exerts a force parallel to a length of the substrate against, the sliding contact. A flux material is provided around the sensing element. Upon detection of an activation condition, the sensing element releases the sliding contact and the force exerted by the spring element moves the sliding contact to another location on the substrate at which the sliding contact no longer provides a conductive path between the first electrode, second electrode, and heater element. The flux allows the sliding contact to move without dragging the sensing material.

摘要： A reflowable thermal fuse includes a conduction element with first and second ends, disposed within a housing. The reflowable thermal fuse also includes an elastic element disposed within the housing and adapted to apply force on the conduction element in an activated state of the reflowable thermal fuse. A restraining element is utilized to secure the elastic element and prevent the elastic element from applying force on the conduction element in an installation state of the reflowable thermal fuse. Application of an activating current through the restraining element causes the restraining element to break and thereby release the elastic element and place the reflowable thermal fuse in the activated state.

摘要： A circuit protection device includes a housing, which includes first and second electrodes. The device includes a conductive slider inside the housing. At a first location within the housing, the slider provides an electrical connection between the first and second electrodes. At a second location within the housing, the slider does not provide the electrical connection. A spring is secured to and stretched between the slider and an inner side of the housing such that the spring is held in tension in an expanded state. The slider is held at the first location by a solder between the slider and the first and second electrodes. After the device is armed, detection of an over-temperature condition causes the solder to begin to melt and the spring to compress and pull the slider to the second location within the housing, thus severing the electrical connection between the first and second electrodes.
