    摘要: The present invention provides a relay with a shape memory alloy (SMA) wire driven mechanism. Conventional mechanical relays rely on electromagnetic principle to operate. Hence, magnetic fields of electromagnetic relays often interfere with magnetic fields of other electrical components, thus resulting in the components physically interfering with each other. The present invention utilizes the shape memory characteristics of a SMA wire to achieve the purpose of changing the operation of the relay. Specifically, when a SMA wire is heated, it restores to its original shape or original length. Comparing to conventional mechanical relays, the relay provided by the present invention does not magnetically interfere with other electrical components, and thus is able to function effectively. In addition, because the relay of the present invention does not require iron cores or coils, available space therein is increased and may be used to accommodate control circuits with various functions.

    摘要: Provided is a reusable fuse having an over-current prevention function. When an over-current that is greater than a reference level is supplied to the reusable fuse and temperature of a positive temperature coefficient thermistor is higher than a specific critical temperature, then an electric resistance of the positive temperature coefficient thermistor increases, a main spring is extended, and thus the spindle is moved toward a side of a housing due to a tensile strength of the main spring and is electrically disconnected from a first lead terminal, thereby continuously blocking flow of current between a second lead terminal and the first lead terminal. When the over-current subsides, then the positive temperature coefficient thermistor is cooled, the tensile strength of the main spring decreases, and thus the spindle is moved toward another side of the housing to be electrically connected to the first lead terminal, thereby allowing the reusable fuse to return to a normal operation state.

    摘要: A thermally activated electrical interrupt device incorporates a thermally activated portion (110) engaging with an electrical interrupt portion (120). The thermally activated material (114) expands when heated, causing an interrupt control rod (140, 180) to open an electrical contact (123, 125, 126/132, 134). When the interrupt device is placed into an interrupt state, a reset mechanism maintains the interrupt control rod (140) in the interrupt state until specifically reset.

    摘要: The thermal circuit breaker and switch has fixed and movable contacts, and non-conductive contact and trip actuators. The movable contact is provided on the free end of a lever arm that normally biases the movable contact toward its open position. The contact actuator transfers movement from a rocker or operator to the movable contact arm when no overload condition exists. The trip actuator is L shaped and rotates in a socket when engaged by a thermally sensitive bi-metallic element so as to allow one end of the contact actuator to float freely, allowing the movable contact arm's bias to open the circuit. The bi-metallic element is so positioned as to engage and rotate the trip actuator only when the bi-metallic element is deformed due to an overheat condition that occurs with an overcurrent. A compression spring acts between the upstanding legs of the trip actuator and the underside of the rocker thus biasing the rocker to the `off` position and biasing the trip actuator to the `reset` position. The rocker employs hooks or posts to engage and position the contact actuator to the reset position after being tripped or manually switched off.
