Definitions
- the present invention relates to a protective element.
- Protective element that cuts off the current that flows through the electronic / electrical device when an abnormality occurs in the electronic / electrical device, for example, when excessive current flows through such a device or when such a device becomes abnormally hot.
- Various protective elements such as bimetal elements, thermal fuse elements, PTC (positive temperature coefficient) elements, and the like are used.

- a thermal fuse element for example, Patent Document 2
- the bimetal element operates more frequently than the supply power increases, and the contact of the bimetal element deteriorates due to this frequent operation, and the original function may not be exhibited.
- the thermal fuse element melts easily due to the increased power supply, and the melting point of the thermal fuse element is higher than the melting point of the resin constituting the cigarette lighter socket, and the thermal fuse blows. Before doing so, I noticed that the resin around the cigarette lighter socket might melt.
- the present inventors examined the use of a disk-shaped polymer PTC element as a protective element for a cigarette lighter socket. Since the polymer PTC element does not have a mechanical contact like a bimetal element, even if the operation (trip) is repeated, the function is hardly deteriorated. In addition, since the resistance-temperature characteristic can be changed relatively freely, it can be operated at a temperature lower than the melting point of the resin constituting the cigarette lighter socket.
- an object of the present invention is to provide a protective element that does not hinder the expansion of the PTC element even when fixed by screws, caulking, or the like.
- the inventors have extended an electrode located on one main surface of the PTC element to a region where the PTC element is not present, and this extended portion is an object (for example, The present inventors have found that the above-mentioned problems can be solved by fixing the entire polymer PTC element to an object by attaching it to a substrate, more specifically a cigarette lighter socket.

Further, the second electrode 6 does not extend into the opening 8 beyond the edge of the PTC element. As a result, as shown in FIG. 1, when the protection element 1 is viewed from the second electrode 6 side, the extension 10 of the first electrode 4 can be seen in the opening of the PTC element 2.
