Abstract
A surge protection device includes a metal terminal and a spring. The metal terminal is located between two metal oxide varistors, where the metal terminal extends beyond the metal oxide varistors. The spring has a flat surface that is connected to the metal terminal using a soldering paste. The flat surface has a bend on one end which forms a gap between the flat surface and the metal terminal.
Claims9
A surge protection device comprising:
- a metal terminal comprising:
- a body disposed between two metal oxide varistors in direct contact with surfaces of the metal oxide varistors;
- a short terminal extending beyond outermost peripheries of the metal oxide varistors in a first direction parallel to the surfaces of the metal oxide varistors;
- and
- a long terminal extending beyond outermost peripheries of the metal oxide varistors in a second direction parallel to the surfaces of the metal oxide varistors and perpendicular to the first direction;
- and
- a spring comprising a flat surface, the flat surface to be coupled to the metal terminal using a soldering paste, the flat surface further comprising an opening to allow air bubbles forming in the soldering paste to be released during the coupling.
