Abstract

This product is an automobile air conditioning device that uses a PTC heater. The terminals are divided into multiple parts in order to suppress the thermal stress that occurs during the manufacturing process and during use, and the cracks that occur in the element due to the thermal stress. The joints are formed in a complex shape to prevent the cracks from extending to the solder that connects the joints of the parts and breaking the electrical path.
