PTC THERMAL PROTECTOR

摘要

A thermal protector using a polymeric PTC element, with broad upper and lower surfaces, sandwiched between and held in intimate mechanical and electrical contact over subtantially its entire broad surfaces with inner broad surfaces of upper and lower plate-terminals. Electrical insulation between the upper and lower plate-terminal outside the area of contact of the plate-terminals and the PTC element electrically insulates the upper and lower plate-terminals from one another. The plate-terminals are clamped mechanically, preferably in such a way that the PTC element is biased continuously against the broad surfaces of the plate-terminals.
