Thermoelectric power generation sheet with overload protection power supply terminal

Abstract

The invention relates to a thermoelectric power generation sheet. A thermoelectric power generation sheet with an overload protection power supply terminal comprises a power supply terminal, wherein the power supply terminal comprises an insulation body and a wiring copper foil, wherein the wiring copper foil is arranged in the insulation body, the wiring copper foil is electrically connected with a thermoelectric power generation unit and provided with a wiring hole passing through the interior of the insulation body, a wiring sleeve is connected to the wiring hole in a sliding way and comprises an insulation segment and a conductive segment, the insulation segment is arranged along the axial direction of the wiring sleeve, the conductive segment props against the wiring copper foil, an air cavity and an overload response air cylinder are arranged in the insulation body, the air cavity is used for heating through heat generated by the wiring copper foil, and the overload response air cylinder is used for driving through gas expansion in the air cavity and driving the conductive segment to be staggered from the wiring copper foil. The invention provides the thermoelectric power generation sheet which can be automatically disconnected during overload and can be automatically connected after normality and is provided with the overload protection power supply terminal, and the problem that a traditional thermoelectric power generation sheet cannot be automatically powered off after overload and cannot be automatically recovered after normality is solved.
