Abstract
A Positive Temperature Coefficient (PTC) assembly, in which protrusions are formed on opposite longitudinal edges of an electrode terminal, PTC elements are held between the protrusions and are in contact with the electrode terminal, an insulating member is attached to an outer surface of the electrode terminal, and a rod cover houses therein the electrode terminal, the PTC elements and the insulating member. A simple structure is realized, fabrication costs are reduced, and a hollow space inside the rod cover is minimized, leading to improved heat transfer efficiency from the PTC elements to the rod cover, reduced noise and a slim structure.
