Electroceramic component
An electric component includes a first base body that connects to a first contact, and an ally conducting element positioned along a current path between the first contact and a second contact. The electrically conducting element melts when an operating voltage of the electric component is exceeded. The electric component also includes an electrically insulating material that substantially surrounds the electrically conducting element and that is arranged so as to prevent an electric flashover between regions of the current path that are bridged by the electrically conducting element.
1. An electric component comprising:
a first base body, which is comprised of ceramic;
a first contact that is on, and that connects to, the first base body;
a second base body, which is comprised of ceramic;
a second contact that is on, and that connects to, the second base body;
an electrically conducting element positioned along a current path between the first contact and the second contact, the electrically conducting element existing during normal operation of the electric component, and the electrically conducting element being meltable due to heating of at least part of the electric component when an operating voltage of the electric component is exceeded; and
an electrically insulating material substantially surrounding the electrically conducting element and arranged so as to prevent an electric flashover between regions of the current path that are bridged by the electrically conducting element;
wherein the electrically insulating material is between the first and second base bodies when the electrically conducting element exists during normal operation.
2. The electric component of claim 1 , wherein the electrically conducting element is thermally screened from the first and second contacts.
3. The electric component of claim 1 , wherein:
the first and second base bodies are bundled;
the electrically conducting element is in a space between the first and second base bodies; and
the first and second contacts contact the first and second base bodies, respectively, on sides of the first and second base bodies that face away from the space.
4. The electric component of claim 1 , further comprising an encapsulation that creates and encloses a hollow space for the electrically insulating material.
5. The electric component of claim 4 , wherein the encapsulation is heat resistant.
6. The electric component of claim 4 , further comprising a housing that surrounds the first and second base bodies, the electrically conducting element, the electrically insulating material, and the encapsulation, and that at least partially surrounds the first and second contacts.
7. The electric component of claim 1 , wherein the first and second base bodies include a varistor ceramic.
8. The electric component of claim 7 , wherein the varistor ceramic comprises ZnO.
9. The electric component of claim 1 , wherein the electrically insulating material drizzles or flows at least under certain circumstances.
10. The electric component of claim 1 , wherein the electrically insulating material comprises quartz sand or glass balls.
11. The electric component of claim 1 , wherein the electrically conducting element comprises solder.
12. The electric component of claim 1 , wherein the electrically conducting element comprises solder with a melting point between about 80° C. and 180° C.
